Automatic control system is the core of whole testboard, can complete pneumatic accessories output pressure, flow, pressure difference, electricity
The detection with electric current is pressed, and the negative pressure of vacuum test condition of simulated altitude is provided for aircraft fuel pump test system；System uses
Microcomputer control, the control of electric ratio and touch screen technology, realize the intelligentized control method of pneumatic accessories performance testing process.
Each state detection signal in scene can be received, the technical parameter of whole test process is recorded in real time, to the reality of collection
Data are surveyed compared with normal data, the automatic judgement for carrying out state of the art simultaneously analyzes record to various signal acquisition process,
With certain fault analysis and diagnosis function, and printing test result team integrated test system has independent manually and automatically control
Two ways processed, under automatic working method, system can perform corresponding process by parameter preset.Manually during control, operator
Member can facilitate the debugging of test system by button or touch-screen execute-in-place, manual mode.
Pneumatic accessories integrated test system is with programmable logic controller (PLC)（Abbreviation PLC）, ratio adjusting valve and touch-screen make
For the core of its automatic control system.
Test system working condition is controlled and adjusted, the automatic detection of pneumatic accessories performance, and energy can be completed
Work and test result to test system each several part carry out real-time display and printing.
Hardware components are mainly called out pressure ratio adjusting valve, touch-screen, printer, input/output module, pressure by PLC, just and become
Device, flow transmitter, electromagnetism on-off valve and each shift knob etc. is sent to form.
Such as Fig. 2, electromechanical gas integral and to be controlled using digital computer to pneumatic system be Fluid Transmission and Control
One important trend of technology development.Pneumatic proportional regulating valve has small volume, control accuracy height, requires low to source of the gas, output
Pressure, flow can not by load change be influenceed, there is pressure compensated performance, can by given input signal continuously, press
Pressure, flow of air-flow etc. are controlled to ratio, so as to realize the high-precision control of continuously adjustabe.
The regulation of annex output control normal pressure, using the Electric proportional pressure-reducing valve ITV2000 of Japanese certain company production, pressure
Power control range (0 ~ 0.49) MPa, the valve employs the feedback control of semiconductor pressure sensor and electronic loop, according to electric
Input signal can continuously, accurately control the output of normal pressure, so that output pressure change proportional to input signal, its
Input/output characteristic.
The combination valve mainly by gas supply electromagnetic valve, exhaust solenoid valve, pilot valve, diaphragm, supply valve port, pressure sensor and
Control loop forms.Its operation principle：When defeated people's signal increases, gas supply electromagnetic valve is connected, and exhaust solenoid valve disconnects.
Therefore, supply pressure is acted in pilot chamber by gas supply electromagnetic valve, the increase of guide's room pressure, acts on diaphragm
Above.Make to be opened with the supply valve port that diaphragm interlocks, a part for supply pressure reforms into output pressure.
This output pressure feeds back to control loop by pressure sensor and carries out action amendment, until output pressure with it is defeated
It is proportional to enter signal, to cause output pressure always change proportional to input signal.When malleation value reaches setting, output
To test accessories the performance detection of annex outlet pressure, flow and annex pressure difference will be carried out as technical conditions, control system.
Such as Fig. 3, the regulation of vacuum control pressure, using the vacuum Electric proportional pressure-reducing valve of Japanese certain company production
ITV2090, pressure control range (0 ~ 101) kPa.The change proportional to input signal of its output pressure, its input it is vast go out characteristic.
Transverse axis is expressed as when signal DC voltage is (0-5) V in use, being flowed into from signal source (4 ~ 20) mA DC current inside valve.
The combination valve is mainly by vacuum pressure electromagnetic valve, air magnetic valve, vacuum pressure valve core, diaphragm, pressure sensor and control
Loop composition processed.Its operation principle：When input signal increases, vacuum pressure electromagnetic valve is connected, and air magnetic valve disconnects.Then vavuum pump
Mouthful（VAC）Connected with pilot chamber, the pressure of pilot chamber becomes negative pressure, and the suction function is on the top of diaphragm.The result is that and film
The vacuum pressure valve core that piece interlocks is opened, and VAC mouths are connected with setting mouth (OUT), then sets pressure and become negative pressure.This negative pressure passes through pressure
Force snesor feeds back to control loop.Action is modified herein, until the vacuum pressure and input signal of the setting of OUT port
Proportional change, its block diagram.When negative pressure value reaches setting, export and give ac pump test system, test system will carry out mould
Intend the outlet pressure of high-altitude condition of negative pressure and the performance detection of operating current.
Such as Fig. 4, PLC programs use the Gx Developer softwares of certain company, the programming software have using it is simple,
Powerful feature, can online programming, facilitate control system debug and fault diagnosis.
PLC main program operational process, according to the characteristics of control system, after program initialization, first determine whether at the beginning
It is manual or automatic, if manually, then performing manual process, now, often presses a button on control panel, just perform
One corresponding action, is generally used for equipment debugging.Pressed if the select button on panel is pulled to automated location, control system
Default program is automatically performed test.Malleation ratio adjusting valve and negative pressure ratio adjusting valve are adjusted by setting value, malleation symbol
Close and test accessories are supplied to after requiring, pressure, flow or the pressure difference of the real-time recording attachment outlet of control system PLC, and to adopting
The measured data of collection compared with normal data, it is automatic carry out state of the art whether qualification determination and various signal acquisition process
Analysis record, and printing test result；Negative pressure is supplied to annex fuel pump test system after meeting the requirements, system is tested by fuel pump
System carries out the technical performance detection of simulated altitude.
Touch-screen selects the TPC1262H of Beijing company, and version configuration software is embedded in using WinCE operating systems and MCGS,
