Fig. 1 is the operation principle block diagram of the utility model.
Specific implementation mode
Below in conjunction with Fig. 1, the content of the utility model is described in detail by specific embodiment.The air data system integrates
The FPGA boards that tester includes industrial personal computer, is arranged on industrial personal computer network interface, it is characterised in that：Further include being arranged in FPGA boards
Dynamic and static pressure execution circuit on I/O interfaces is arranged in the static pressure dynamic pressure port of dynamic and static pressure execution circuit output end, is arranged in static pressure
Capsule instrument on dynamic pressure port, the voltage analog module being arranged on the ports FPGA board RJ15 and sensor acquisition module,
The capsule instrument being electrically connected respectively with the static pressure dynamic pressure port output end of voltage analog module and dynamic and static pressure execution circuit, sound
The static pressure dynamic pressure port for pressing execution circuit and the input terminal of sensor acquisition module are electrically connected.Wherein, dynamic and static pressure execution circuit
For controlling the given of sound potential source and adjusting.
In use, variation and adjusting supply capsule instrument of the dynamic and static pressure execution circuit by air source.Sensor acquisition module
Acquisition in real time is exported to the dynamic and static pressure size of capsule instrument.After upstream industrial personal computer is by network interface and FPGA communications, by operating boundary
The software in face operates, and control instruction is sent, and FPGA boards send an instruction to the work of dynamic and static pressure execution circuit.Dynamic and static pressure executes electricity
Road, at pulse switch amount, controls instruction morphing dynamic and static pressure by relay and generates process, to realize the given of different air-flows.
And the sensor acquisition module configured on FPGA boards, the pressure size of dynamic and static pressure port output can be acquired in real time, configuration
Voltage analog module can simulate the analog voltage signal needed for tested capsule instrument.
