Background technique
Pressure diaphragm capsule is as certain model icing signaller main component.When carrying out detection test, it need to be made in certain gas
It works under the conditions of pressure；Atmospheric pressure value when recording work simultaneously, to judge whether pressure diaphragm capsule works normally；According to test demand, gas
Press strip part should be changed by regulation lift curve and rate of change；Test process need to be repeated as many times and carry out.Now without special test
Equipment, for its test；Manufacturing enterprise simultaneously records number by manually controlling air pressure change, artificial interpretation pressure diaphragm capsule working condition
According to method carry out detection test.Detection process is cumbersome, and measuring accuracy is not high, and test can only test a capsule stack effect every time
Rate is low.
Summary of the invention
The purpose of this utility model is: a kind of pressure diaphragm capsule detection device is designed, for solving current manual testing's efficiency
Lowly, the not high technical problem of precision.
To solve this technical problem, the technical solution of the utility model is:
A kind of pressure diaphragm capsule detection device, the detection device include: programmable logic controller (PLC), pressure sensor,
A/D module, pressure controller, pressure source；
The pressure source is connect with pressure controller；The pressure sensor output end is defeated with A/D conversion module
Enter end to be connected；The pressure controller is connected with tested pressure diaphragm capsule；The programmable logic controller (PLC) and A/D modulus of conversion
Block is connected by data line；The programmable logic controller (PLC) is connected with computer by connection.
The pressure source is made of vacuum pump and gas cylinder.
The detection device further include: computer, the computer is connect with programmable logic controller (PLC), for providing number
According to display and storage.
The pressure source is connect with pressure controller by sebific duct.
The pressure controller is connected with tested pressure diaphragm capsule by sebific duct.
The programmable logic controller (PLC) is connected with computer by RS232 connection.
The pressure sensor is used for the pressure of measuring air pressure environment, by A/D conversion module and sends programmable patrol to
Collect controller.
It is operated conveniently the beneficial effects of the utility model are: the utility model pressure diaphragm capsule automatic acquisition equipment has, from

Detailed description of the invention
Fig. 1 is the principles of the present invention block diagram.
Specific embodiment
The equipment of the utility model is described further with reference to the accompanying drawings and examples:
Pressure diaphragm capsule detection device as shown in Figure 1, comprising: programmable logic controller (PLC), pressure sensor, A/D mould
Block, pressure controller, pressure source；Vacuum source and gas cylinder are as pressure source；Pressure controller is to provide lift curve and variation speed
Rate provides the air pressure environment in test process to tested pressure diaphragm capsule；Pressure sensor is used for the pressure of measuring air pressure environment, by
A/D conversion module simultaneously sends programmable logic controller (PLC) to；Programmable logic controller (PLC) receives signal when pressure diaphragm capsule work；
Computer is connect with programmable logic controller (PLC), is shown and is stored for providing data.Programmable logic controller (PLC) selects Mitsubishi
FX3U-16M/R type, A/D conversion module select FX3U-4A/D type, and pressure sensor selects Xi'an outstanding really CYG1003T, pressure
Controller selects Druck PACE5000 type, gas cylinder to select full GB5099 type nitrogen cylinder, vacuum pump that VALUE is selected to leap type.
The application method of the utility model is as follows:
Two pressure diaphragm capsule pressure interfaces, pressure sensor interface, pressure controller output interface are connected using rubber tube；
Gas cylinder, vacuum pump are connected respectively to pressure controller positive pressure, negative port；Using RS232 communication line connection pressure controller with
Computer；Programmable logic controller (PLC) and computer are connected using private communication line；The output signal of pressure diaphragm capsule is connected to programmable
The input port of logic controller.After start-up operation, pressure controller exports certain air pressure；When pressure diaphragm capsule work, PLC
Automatically its output signal is received；Computer passes through the pressure of programmable logic controller (PLC) and A/D conversion module read work point simultaneously
And record preservation.After pressure controller completes an escalation process, progress is repeated, until stopping after completing setting testing time
Only.
