The proportional controller includes single-chip microcomputer, power driver module and power module, wherein single-chip microcomputer and power driver module It is connected, power driver module is used for coil power supply to drive armature motion；Power module is used to power to power driver module, Direction diode, current-limiting resistance and π type LC wave filters, the direction diode that the power module includes being sequentially connected are used for Infringement of the reverse power connection to circuit is avoided, the current-limiting resistance includes the protection that 2 power in parallel are 0.25W, resistance is 1 Ω Resistance, for preventing coil short from burning circuit board；The π types LC wave filters are used to weaken the Ripple Noise in circuit, and it is wrapped Include 2 capacitors and 1 inductor；2 bypass electric capacity also in parallel, current-limiting resistance and π types LC filtering before the direction diode 1 transient voltage suppressor is also parallel between device, for the voltage peak in suppression circuit；The power module it is defeated Go out end while as the stand-by power supply of built in pressure sensor, it is passed by relay, step-down transformer and the built-in pressure Sensor is connected；Power supply detector is provided with the normal work power supply of the built in pressure sensor, when Power supply detector detects During to the normal work power loss, transmission level signal to relay, relay in the presence of level signal adhesive from And the module that switches on power is powered to the circuit of step-down transformer to built in pressure sensor.

5. a kind of rotary type camera device according to claim 4, it is characterized in that, when built in pressure sensor detects Feedback pressure be less than setting pressure when, proportional controller increase coil output current, distance rod thrust increase, main throttling The aperture of mouth becomes big so that the output pressure increase of delivery outlet, now the first control valve or the second control valve are operated in decompression shape State；Conversely when the feedback pressure detected is more than setting pressure, proportional controller reduces output current, and the thrust of distance rod subtracts Small, primary choke is closed, and overfall is opened, and the air in pressure regulating cavity is discharged to air by overfall, and the pressure of delivery outlet reduces, Now the first control valve or the second control valve are operated in overflow situation.
