Machine pneumatic accessories testing stand, computer become the core of test system, and control software is set using modularization, progressive structure
Meter, by KingView software development, the test for making pneumatic accessories of aircraft is more succinct reasonable, more intelligent.
The content of the invention
The present invention proposes a kind of pneumatic accessories of aircraft testing stand based on computer control, can be divided into test system and control
System two large divisions processed is, it can be achieved that pneumatic accessories air mass flow, pressure, electric current, voltage, time, angle, displacement and load electricity
The automatic measurement of the Common items such as resistance, test data handles by computer automatic analysis, result by computer output printing simultaneously
It automatically saves in the database.
The technical solution adopted in the present invention is：
The pneumatic accessories testing stand mainly includes air-channel system, circuit system and other test systems.
The test of the pneumatic accessories air path part mainly includes pressure test and flow rate test.
In the entire test system, computer and PLC constitute the major part of test system, the test of pneumatic accessories
Whole process is by computer monitoring, the main data acquisition of computer, processing, analysis, calculating, storage and drafting trial curve
Deng.
The computer control system is mainly by computer, printer, PLC, pressure-control valve, data conversion module, pressure
The compositions such as force snesor, flow sensor, differential pressure pickup, solenoid valve.
The monitor and control system software design is realized using configuration software, mainly including man-machine interface, parameter setting, experiment
Items selection, trystate monitoring, trial curve are drawn, result of the test printing and the work(such as historgraphic data recording, file management
Energy.
The beneficial effects of the invention are as follows：The testing stand uses the control mode of computer control PLC, and control software uses mould
Block, progressive structure design, by KingView software development.
Description of the drawings
Fig. 1 is the experimental bench system figure of the present invention.
Fig. 2 is the computer control system total figure of the present invention.
Fig. 3 is the software flow pattern of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, pneumatic accessories testing stand mainly includes air-channel system, circuit system and other test systems.
Pressure test and flow rate test are mainly included to the test of pneumatic accessories air path part.Pressure test is mainly pair
The test of the working range of pneumatic accessories pressure-regulating valve;Gas flow test, test event include inside and outside leakage rate and always let out
The small flow rate test such as leakage quantity.
Testing current, voltage tester and frequency test are mainly included to the test of pneumatic accessories circuit part.Pneumatic valve
Electrical component mainly have solenoid valve, electric notor and electricity turn round 3 type of valve, according to the CMM handbooks of pneumatic accessories, formulate testing stand
Circuit output parameter, main test accessories parameters such as electric current, voltage under given conditions.
Other tests：The test of some pneumatic valves needs to measure the opening degree of valve butterfly disk, that is, needs
The measurement of angle.The open angle of butterfly disk is usually no more than MO, is closed completely in AO, and 90 ° of whens open completely, during measurement,
Angular transducer is directly installed on the butterfly disk nail bar of test valve.Also the test of some pneumatic valves needs the work to valve
Dynamic component carries out the test of displacement, and moving range is no more than 200mm, and the displacement sensing that a range is 0 ~ 200mm may be selected
Device measures.
Such as Fig. 2, in entire test system, computer and PLC constitute the major part of test system, pneumatic accessories
Test is whole by computer monitoring, and the main data acquisition of computer, processing, analysis, calculating, storage and drafting experiment are bent
Line etc..Liquid crystal display is mainly used to carry out man-machine interface operation, state measurement parameter is shown, trial curve and the results show
Deng.Each pressure output/analog quantitys such as input port pressure and flow, temperature gathered by each sensor and pass through 16 it is high-precision
Degree A/D capture cards are sent to computer.PLC controller is communicated by RS-232 with computer.Each airline pressure is adjusted
The on-off models such as valve, the unlatching of flow control valve, electromagnetic valve switch state realize logic control and interlocking work(by PLC
It can so that system operatio is simple, safe and reliable.PLC controller presses each pressure-control valve, solenoid valve, flow control valve etc.
It is required that it is operated.
Computer control system is mainly passed by computer, printer, PLC, pressure-control valve, data conversion module, pressure
The compositions such as sensor, flow sensor, differential pressure pickup, solenoid valve.
Monitor and control system software design is realized using configuration software, mainly including man-machine interface, parameter setting, pilot project
The functions such as selection, trystate monitoring, trial curve drafting, result of the test printing and historgraphic data recording, file management.
Such as Fig. 3, testboard interface mainly includes 3 parts：First, parameter setting part before testing will test
Flow and parameters set storage in advance, in case test；Second, part of detecting carries out the test of all kinds of pneumatic accessories.Bag
It includes master switch control button, pressure regulating valve knob, the switch control knob of each valve of test and each sensor of display and passes through string
The data that oral instructions are returned, including each pressure, the numerical value of flow and temperature sensor is shown；3rd, test data record storage part,
Test data is write to test data list by the clock interval that PLC is determined, and test data list is preserved in the database.
Since the repair of pneumatic accessories of aircraft will be according to parts for maintenance handbook (COMPONENT MAINTENANCE
MANUAL related request), pneumatic accessories testing stand all must establish test and maintenance scheme according to the relevant criterion in handbook.This
Testing stand is exactly according to being required in CMM handbooks, to the pneumatic accessories progressive of low pressure and mass flow, the small flow operating condition of high-low pressure
It can test, by computer complete monitoring.
It is found by the analysis of each pneumatic accessories test process in CMM handbooks and requirement, the test per class attachment is all
It is made of test condition, the operation of each valve and corresponding time.Therefore, to ensure the generalization of test software, survey
Flow is tried by the way of time-event triggering.
In the test of attachment, since the test technology of all kinds of attachmentes is different, its test step in computer testing flow
Rapid and the triggered time number n is also different, therefore when designing test software using cycling come the knot of optimal inspection software
Structure.
