Be used for the display device of display controller to the Signal Processing result.
Also be provided with the source of the gas that inserts tested valve.
When the portable air valve of the utility model detects integrated system works, at first give drive plate, carry out signal by drive plate output again and give tested solenoid valve by the controller output control pulse, and then the break-make of control air-flow.Solenoid valve valve port setting pressure sensor detects the pressure signal that gas jet produces.Detection module will be gathered control signal, execution signal and actual signal, feed back to controller, compare display waveform on display device.
Described controller can adopt computer or single-chip microcomputer, and display device is generally display.
Certainly the data when gathering solenoid valve work must have source of the gas to import gas to solenoid valve, and source of the gas can adopt any device that pressed gas can be provided in the prior art.
The portable air valve of the utility model detects integrated system on function, can
A. to the input of drive plate control signal/go out;

C. drive plate is to the detection of solenoid control signal;
D. the pressure of solenoid valve output gas flow/gas speed detects;
E. the demonstration of each signal.
The portable air valve of the utility model detects integrated system, can on computer screen, clearly reflect the waveform, air pressure monitoring device of the waveform of output signal, the voltage that produce to drive or current signal inductive waveform, comprehensively judge qualification rate by rate of change, responsive speed etc. to the injection air pressure of air valve.
Description of drawings
Air valve CAT system of the present utility model, adopt " PC+AD/DA integrated circuit board " and phase inductive sensing, translation circuit to form the hardware system that signal takes place and gathers, special software in conjunction with establishment is formed the air valve test macro, to substitute signal generator of the prior art and X-Y recorder.Reduced hardware device like this, realized the quiet dynamic test of air valve equally, had that data acquisition, processing, performance graph show in real time, a function such as printing and data preservation.Reduced the volume of test board, be easy to carry, easy to operate, come into plain view.
Fig. 1 is the structured flowchart that the portable air valve of the utility model detects integrated system;
Fig. 2 is the circuit structure signal that the portable air valve of the utility model detects detection module in the integrated system.
Embodiment
Referring to Fig. 1, the portable air valve of the utility model detects integrated system, comprising:
Be used for carrying out the drive plate of signal to tested valve output;
Be used to respond to the pressure transducer of tested valve export pressure signal;
Be used for sending the controller of control signal to drive plate;
The detection module of be used to obtain described control signal, carrying out signal and pressure signal, detection module is handled the signal feedback of obtaining to controller;
Be used for the display device of display controller to the Signal Processing result.
The portable air valve of the utility model detects the mode that integrated system specifically adopts " PC+integrated circuit board ".PC has the fast advantage of data processing speed as controller, and has Presentation Function simultaneously.
Advantages such as drive plate directly links to each other with PC with the form of detection module with integrated circuit board, finishes the task of input, and this mode has portable practicality, and man-machine interaction is convenient.
Show the quality of judging air valve to the control of solenoid valve action and on interactive interface thereby utilize PC to finish.
When the portable air valve of the utility model detects the integrated system use, at first tested valve is inserted drive plate, pressure transducer is installed in the outlet of tested valve, export control signal to drive plate by PC through USB interface by software, drive plate is powered by the 24V stabilized voltage supply, receive after the control signal that PC transmits, can produce execution signal (promptly applying driving voltage) to tested valve, tested valve is carried out signal driving carrying out work, the air pressure that tested valve export produces produces pressure signal by pressure transducer, the detected module collection of pressure signal, detection module is acquisition controlling signal and carry out signal synchronously also, detection module is given controller with the signal feedback that collects, and compares, display waveform on the last display device.
Detection module can be changed sampled point by parameter configuration in gathering various signal process, acquisition range, and parameters such as matching range, for example:
Driving signal frequency:,, satisfy the demand of air valve test for low frequency and high frequency so in order to test comprehensively, drive signal is also wanted to regulate speed because of air valve is supported 1K even higher frequency of operation;
Acquisition range: strong and weak different because of different signals, the ratio of demonstration is just different, for the ease of observing, all is on the basis of time t at horizontal ordinate, and the span of ordinate is wanted and can be adjusted;
Matching range: count the due reference of different waveforms according to accumulation data and weigh waveform, compare with the waveform of each collection, can carry out the adjustment of measuring similarity according to the standard of 0%～100% (increasing progressively by 10%) in parameter configuration, satisfaction degree is represented final qualified amount by matching degree;
Matching degree: can export the qualified coupling ratio of the matching degree parameter reflection controller of 0%～100% (increasing progressively) at last, as thinking that this tests the quantitative judgement of air valve quality by 10%.
At last, controller is handled the signal that obtains, and shows the qualification rate of tested valve at last on display device by waveform.
