This can reach by following method, be that gig braking system monitoring device comprises two pressure sensors and a relay, this relay is connected with each sensor respectively, according to the present invention, this device also adds the controlled difference of pressure signal amplitude detection device that is one another in series, integrator and comparator unit, controlled difference of pressure signal amplitude differentiates that each input end of parts is connected with corresponding pressure sensor respectively, the mouth and the relay of comparator unit join, optional feature is connected the multi-vibrator of another input end of integrator in addition, and the voltage programmer that is connected with another input end of comparing unit.
If add a memory device again in the gig braking system monitoring device, that is just better, and the input end of this memory device should be connected with the mouth at comparator, and its mouth is then received on the relay.
Best, the controlled difference of pressure signal amplitude detection device in the gig braking system monitoring device includes one group of series connected differential amplifier and difference of pressure signal amplitude discriminator circuit.
Wise way is to adopt comparator as the comparing unit in the gig braking system monitoring device.
Following way is favourable, i.e. crystal triode of memory device installing in the gig braking system monitoring device, and its base stage is connected the mouth of comparator, and emitter is connected on the relay.Also install a control key, a lead-in wire of key is connected with transistorized emitter by the normal opened contact of relay, and another lead-in wire then is connected with transistorized collecting electrode.
The present invention can finish the pressure in each parts of brake system is carried out continuous control, thereby has improved the safety of gig work.
In addition, the present invention can find fault in the working process of brake system, thereby has improved the reliability of gig.
The present invention simultaneously can also find the fault in the brake system in advance, and this has just greatly shortened the time of finding the brake system fault.
Below in conjunction with accompanying drawing specific embodiments of the invention are set forth with explanation the present invention.
