Research on the intelligent controller of high-pressure air compressor for 86-paying instrument Yang Qiliang Xing Jianchun Wang Ping Liberation Army Engineering Workers Engineering College, Nanjing 210007 machine 8 Shen 1 internal structure model, standing the air compressor 86 plus communication language system The dumb island air compressor becomes an intelligent subject with self-management and control 1+ ​​diagnostic communication and communication capabilities, effectively overcoming the shortcomings of traditional manual and centralized monitoring methods.

i Introduction High air compressors are large-scale equipments that are widely used in industrial production and military fields. They use air as a medium to produce compressed air and provide high-pressure power sources for pneumatic mechanical pneumatic tools or other equipment. Before the squatting, the maximum exhaust pressure of the high-pressure air compressor can reach several tens of MPa, which is highly dangerous during the operation. The traditional artificial mechanical equipment suddenly disintegrates and other causes of personal injury; and the high-pressure air compressor is working noise. Extremely, it is difficult for technicians to monitor the operation status of the equipment during the field time, which makes it difficult to detect the signs of failure during the operation of the equipment. If the air compressor equipment fails or is damaged, both economically and militarily Cause serious damage.

In response to the above question, there has been a remote centralized monitoring scheme for air compressor units. This scheme uses the air compressor unit as the controlled equipment of the Tongtong, and uses computers and tools to implement monitoring of multiple units. It solves the problem that the monitoring and control of the unit operation and the safety of the operator cannot be performed remotely for a long time.

However, the shortcoming of this scheme is also obvious that the control logic set of more than one unit is on the monitoring computer of the station, resulting in a dangerous set, causing the failure of the application point, the chain between the units is realized by the monitoring machine, and there is no direct linkage mechanism; When there are more, the implementation of the machine monitoring program will become extremely complicated.

It can be transformed into a smart device from a traditional dumb device.

The human-printed controller is embedded in the device body, and each air-pressure device becomes an intelligent main body, and has the ability of self-management and control for self-diagnosis communication and communication. This implementation scheme distributes the control logic to separate devices for execution. The single device can run independently from the upper monitoring host, and the intelligent air compressor device can be white. Interacting with each other greatly reduces the complexity of implementation when monitoring multiple units.

The basic concept of 2 6 6 and the software and hardware system based on the 6-control principle and pre-moving ability m.Minsky published in 1986, the mental society Society, first proposed 6 plus, that the dishes in the society are negotiated The solution to this question is that the individual is the 6th 14.6 paying basis. The idea is to enable software to simulate human social behavior and cognition, that is, the evolutionary mechanism of organizational interaction in human society, and the way of cognitive thinking and problem-solving. . Compared with the traditional object concept, the six-pay concept has more knowledge, mobility and collaboration, and has stronger problem solving ability and autonomy.

The concept of distributed systems based on 1 has caused people to jump into the limitations of the client server system and adapt to the development of distributed application solicitation. From the perspective of development, the concept of 6 o'clock can be divided into the following reactive architectures in the distribution calculation according to the difference between the mechanism of the internal data structure of the six 1 and the zinc of the action decision. 6 The process of his reaction to related events, such as the Gaby group, facilitates the control system that activates a process based on the perceptron. The activity of the 8 post is caused by the stimulation of internal and external dishes.

Prudential architecture, 6 out of 636, such as the filter has a muffler function is sucked into the air compressor cylinder 6 through the reciprocating piston action, so that the inhaled air is allowed to shrink in the cylinder. From low pressure to high pressure, and then exhausted through the exhaust valve and the pipeline, the air with constant volume and pressure is obtained. Because the volume of air changes from small to high, the heat is generated. In order to improve the efficiency of the machine and reduce the energy consumption, the compressed air needs to be cooled and separated in the production process to separate the oil water and solid impurities, and then sent to the gas cylinder to facilitate the enthalpy. In some cases, there is a higher requirement for the quality of the compressed air, which requires post-treatment of the compressed air. If you use a dryer and a filter, you can get high quality air. In order to obtain the required pressure, the high-pneumatic machine usually has a 4-stage cylinder, which compresses the air in stages, and the process flows.

4 high-pressure air compressor 纟 6 pay design, 8 print 1 decision is made through the logic or quasi-logic of Keding template matching and symbolic operation, such as 4 people make decisions after careful consideration, flash this wave called Curtain-style architecture.

Mud-style architecture kisses 64. These two + systems are hierarchical and are in violation of the latter.

Based on the six seals of the screwing foot, a new research field 5 is intelligently screwed, meaning that the control is based on 6 payouts. The six-layer 6-pay interacts with the environment through sensors and actuators, and it has a feedback mechanism with traditional control and other control samples.

The principle of the ç½” foundation 6 3 3 high-pressure air compressor process principle of nature 1 mountain air in the atmosphere too force, after the air inlet 4.1 high-pressure air compressor Ming Hao intelligent controller hardware platform according to high-pressure air twisting machine The process flow scale determines the main monitoring parameters as the suction pressure, the fourth-stage exhaust gas, the exhaust gas volume, the cooling water flow, the cooling air pressure, the outlet air temperature, the cooling water temperature, the unit inlet cooling water pressure, the sewage valve control, and the state compressor operation state. Alarm status, etc., as well as operational control logic such as manual drain automatic stop and stop start control and emergency stop control.

The high m air compressor AgentJ controller hardware platform consists of two parts: 0051 Xian 655 distributed processing unit 10 module and local bus. 3.

VUUIliUjrf.; The valve is set to the singularity of the singularity, reported as a negative, the threshold is developed by embedded technology developed by the embedded high control computer, using the 10646廿 embedded operating system to provide liquid products The touch screen human-computer interaction interface provides an Ethernet interface to communicate with the host computer. The unit collects real-time data and status of each module, and completes the implementation of the processing control logic and protection functions such as delay, shut-off sewage valve, and the like. Although the simulation module is used for simulation, it mainly uses the analog input of ten cylinder temperature and pressure to input the nickname. The switch state acquisition module monitors the operating status of equipment such as dry valves. Switch 跫 control module, mainly used for operation control alarm output. The local bus is also a fieldbus.

4.2 The model structure of the high-pressure air compressor 486 According to the operating characteristics of the high-pressure air compressor unit, the high-pressure air compressor determines the operation health of the current unit to reason and diagnose the fault, and realize fault diagnosis and automatic protection. The fixed negotiation strategy cooperates with other units of six 86 pay to realize the real-world environment between the units through the sensor, and the output is reacted to the environment through the effector to achieve real-time control of the unit equipment.

Under the control of this hybrid architecture, the kernel scheduling is performed by the air compressor unit. Because each component must be executed, a synchronization mechanism is required to operate the entire 6-time time standard, and the timing of the entire system is maintained. Sex.

The perceptron and the real-time database perceptron component realize the collection of the operating parameters of the unit equipment, and store the collected data in a real-time database.

The real-time database dynamically stores the operating parameters of the device in the form of memory. The 8th print can automatically realize the maintenance of the real-time database, and the real-time library can be created to dynamically increase the real-time library size or reduce the real-time update and access of real-time data records.

Command Queues and Effector Effectors, also known as actuators, send control commands to the unit control unit via the effector to control the unit. To mention, for the execution efficiency and security of the instruction, a command queue is designed to realize the buffering and management of batch instructions, and at the same time, it can effectively prevent the loss of control commands.

The communicator and the human-machine interface communicator are the interfaces of the six-eighth printing and the other eight-in-1 communication, which is implemented by using 50-butyl technology to ensure the real-time and reliability of communication.

Human machine interface. Provide 010 Yang 161 his juice 3, image equipment operation process failure alarm information control button and other paintings, to achieve unit management and maintenance personnel on-site monitoring.

The human machine interface is also understood as a special communicator.

The knowledge base knowledge contains 8, the internal relative fixed and the need for global common domain knowledge, including air compressor unit related knowledge, such as the upper and lower limits of the exhaust pressure of the unit, etc.; the control knowledge base includes the execution of control logic The basic knowledge, such as the sensor's range parameter control related time parameters. The knowledge base can be updated online based on new changes in the kernel.

The control logic of the control logic high air compressor unit mainly includes: automatic blowdown control logic hand 6 start and stop air compressor control logic emergency stop control logic inlet valve control logic compressor speed and cooling water flow most dynamic control logic. Control logic algorithm execution, fault diagnosis and protection High air compressor unit six 8 printing 1 provides two levels of fault diagnosis primary over-limit judgment and report advanced intelligent algorithm based fault diagnosis.

The primary over-limit judgment and alarm, according to the data limit range set in the knowledge base, according to the equipment operating parameters collected in the real-time library, determine in real-time whether the equipment operating parameters exceed the limit or not, and use the same alarm level as the other six The printing 1 or the equipment operation management personnel are obviously abnormal, and in a serious case, the control command can be issued to forcibly stop the faulty equipment in the operation to automatically take other protection measures.

According to the operating characteristics of the high-pressure air-torque unit, Print 1 provides the unit's rapid protection strategy, including cooling water shortage report and protection oil pressure low report and protection of 1 to 4 exhaust temperature alarm and protection Class 1 to 4 exhaust pressure over alarm and protection motor short circuit or overload alarm and protection.

Negotiation strategy High-pressure air compressor units use multiple units in a joint operation mode. Therefore, the units need to adopt corresponding negotiation strategies to achieve coordinated operation. For the air compressor station, the main difficulty lies in how to control the number of start and stop of the unit to ensure that the pressure of the gas supply pipe can be stabilized at a given value. To this end, for the different situations, the following two units of the printing 1 negotiation strategy, a single 8-print 1 numbering strategy and a 6-plus group numbering strategy were developed.

The single printing 1 numbering strategy is applicable to the case when the number of air compressor stations is small. The main idea is to start and stop each of each fleet. For example, if the three units are used, the negotiation strategy is to assign a number to each of the six payouts, 16 for 261 and 36, and 31 to 86 for the air compressor to operate first, while the compressed air mains pressure is still low. Then, 186 pays 26 pays for negotiation, and 286 pays to start the air compressor; if 2 starts failing, then 1é‚›386 pays for consultation and the corresponding air compressor.

Still low, then 2 6 86, the first bamboo and 1 6 6 paid to start its air compressor 186 æ³” start failure, then negotiate with the 386 to start the corresponding air compressor. The air compressor of 3`l13Agent is first transported, and the pressure of the compressed air main pipe is still low. Then the start 3 is called 1 and the air compressor is started in consultation with 186; if 1; the start air compressor fails, then pay 26 Negotiate to move its air compressor. When the three tie machines are running and tripping, then it is necessary to immediately start the other standby 86 when the condition is notified.

In many cases, the idea is to group the groups, each group, number, good ancestor, one-person, one-generation, group, exercise the right to negotiate, each group of six 86 has the same behavior at the same time, at the same time stop. The air compressors of each group are activated in turn according to the group number. The group start strategy is a single six 8 sink 1 number strategy phase, no longer on.

5 high-pressure air compressor unit 4, the communication language is more than six 6 pay system, pass; = is to achieve six 86 deduction cooperation is to exchange some information, which requires the corresponding language to describe and describe these. The format of the six-in-1 communication language is the grammar and connotation, that is, the semantics. It supports the six-in-one-in-one interaction and understanding of these messages. Currently and the people. These words are based on speech act theory or order predicate theory and have a strict grammatical composition. Although the above several language systems are relatively complete, they are more cumbersome to implement, which is disadvantageous for sub-real-time communication scenarios.

In order to realize the real-time reliable unit 8-print communication system between the six 6 payers of the high-pressure air music unit. The basic statement is the control command statement 0010156 command to return the statement, 01301 feet 65 port 0 still 610 data request statement, 813 people 69 this 5, data return statement, 339, chat parameter modification language high pressure air jade unit printing 1 communication language The connection link of the object Qiu uses a point-to-point direct multiplication method, that is, the 7 protocol is used to directly establish a connection between the two parties. The communication connection is based on the basic operation of the network standard communication WinSk. socket Sockets to support the TCP1P protocol on the 0-to-5 series operating system, in order to treat the color-coded words as different. The endpoint of the seven-machine process for two-way communication. At the present time, the use of the connection to the Ding, twisting the sword, and recovering Connor here with the base control command command execution, the statement 0 data request statement 10 data return statement as an example to illustrate.

Control command statement 卞. To be used for six, ask each other to send control commands. Its language format is 5.

18, 1 note 6 pay X 6 is the head identifier of the statement, this statement uses the message processing module real-time database elimination, the queue high-pressure air compressor 8 sink 1 uses 0++ as a development tool to achieve. 9 is the software implementation structure of the high-pressure air compressor 6. It integrates a variety of advanced computer software development methods such as 1-way object technology multi-threading and its synchronization technology queue technology. In order to achieve the interaction of the public.

5, such as the format of the interface and the meaning of each part of the warfare is the same as the previous statement. Here, the 336 oil is used; 0, 6 means B, also the interface, the return value after executing the control command must have 0 command execution success, 1 communication card no response, 2 node response, etc.;

(3) Data request statement The data request statement is used for a certain 8-print 1 to take another relevant operational data. Its language format is 7.

Used as an identifier, the server first determines the header identifier to determine the type of the statement, and then executes the corresponding processing code. , also control the command 00, such as the module's address number such as 2, 3, etc., to specify which control module to send control commands; 03,0,16 Pan to 10 module specific command content, such as DOlON; CRC is the cyclic redundancy check Cycic ruler 6 cents 300, used to verify the correctness and integrity of the data transmission. This system uses the ç”™16 check algorithm Ding 3138 tail mark, when the server receives the mark, I think that the entire command string has been accepted, ready for the next step, and the wood statement is used as the end mark.

(2) Command Execution Return Statement The command execution return statement is used to return the success or failure of the execution of the control command by the receiving six 8, 1 to send 86. Its language 1 format 6.

The instrument journal data is taken from the database. , vote, page 8 is the same as the first two statements.

(4) Data Response Statement The data response statement is used to request the six prints to return to the requester, respond to the data request and return the data. Language format 8.

The format of the statement and each part are basically the same as the above statement. Only the software implementation end 61 of the high-pressure air compressor 48, 1 determines that the sent statement sent by the client 6 contains symbols, and prepares to retrieve data from the real-time database. .

Agent needs the requested data in the server-side Agent real-time library to measure the point number, the server-side 6 pays according to these numbers from the real-time number, the air compressor 6 deduction of the human-machine interface ± press machine Ting protection block air compressor control logic school Block high-pressure air compressor unit 86 pays for communication language only, object, 61-link link adopts protocol, realizes point-to-point point-to-point communication mode, and establishes connection directly in communication. The communication connection is implemented based on the Sl series 105 operating system. The network is the application standard, the socket. Socket 8, is also the network operation unit that supports the 71 protocol network, which is mainly divided into D, and 叩, two ways. When the deduction language is implemented, the full duplex mode of the connection is adopted to ensure the reliability of communication.

7 Application of intelligent controller for high-pressure air compressor for 66å’• A certain air compressor station has 8 sets of 6610 high-pressure air compressors, the highest art flow monitoring equipment control, etc. All the obvious data is paid through the interface six 6 Air compressor six 86 payment results.

The pressure of the row is up to 24.5 MPa, forming a complex air compressor group.

The actual composition of the air compressor station contains a low-pressure air compressor called 1.213, which is connected to the 872001. Eight air compressors transmit high earth gas to the pressure bottle through the mother symbol, and supply air through the high pressure gas cylinder.

According to the characteristics of the empty station, the phase control monitoring 5 distribution group base Dingshan small 6 when the computer control system structure 12. Zhongshan centralized monitoring six 86 pay and 8 high pressure air compressor the entire empty 1 station earth play people The machine interaction, surface, and bursting tools use T. industry control configuration software iFix, and its running platform is Windows XP operating system. Each unit assembly is based on the six-eight-in-1, pressure air compressor controller 502, high-pressure air compressor six, 6 o'clock, each independent and complex Lime logic to perform fault diagnosis and protection functions . The communication language of the high-voltage air-powered machine six 81 is based on the six-eight-print 1 communication proposed by the text along the ancient only, like 湮锵中,槲, Ding Yang, through the language in accordance with the negotiation strategy proposed in the text to achieve mutual negotiation and cooperation. Because the set monitoring 86 pays for the general configuration software, it does not support the 1 language system itself. In order to realize the high-pressure disc press 6 when 1 〃 set monitoring six 6 pay communication, specially developed to pay 6 pay, the 6 plus women hold redundant communication language, how can the 1 communication protocol be converted to 0 six agreement 1 Hong's kind of data access is discussed, and high-speed data exchange between them is realized.

Therefore, this control structure is a combination of centralized monitoring and decentralized control, and has been applied in the past. The centralized monitoring road monitoring and painting, but including the parameter monitoring parameter alarm work centralized monitoring, 6 pay interface people 6 æ³” high twist air nozzle high pressure air compressor island pressure air also machine, pressure empty melon machine Dang pressure curve, from 14 In the case of no, the pressure curve changes smoothly, and the base wood remains at around 24.5 MPa. Therefore, the air compressor group hybrid computer control system based on this intelligent controller for high-pressure air compressor realized by 86 pay has received good control effect.

8 Conclusions The intelligent design of the high-pressure air compressor unit is realized by the method of 86-oriented, and the intelligent equipment suitable for the operation of the high-pressure air compressor unit is characterized by self-autonomous self-diagnosis self-protection communication and communication, which effectively solves the problem. The traditional manual centralized monitoring of the group and the safety of the operators.

The intelligent controller of high-pressure air compressor unit based on six 8 printing 1 has been successfully applied in several high-pressure air compressor stations, which has good control effect and effectively improved the operation, management and maintenance of high-pressure air compressor station. .
