Controller is connected with liquid level sensor, magnetic valve, power supply, indicator lamp respectively by signal wire.Detection switch one end It is connected with positive source, the detection switch other end is connected with controller.High pressure fuel source is by fluid pressure line by magnetic valve and inspection Survey is connected with fuel tank;
The course of work of the present invention:
Control whether detecting system works by a detection switch.Detecting system is according to detection when detection switch closes conjunction The signal that switch provides carries out body gesture detection, and then body gesture detecting system is stopped when detection switch disconnects, now Alarm lamp is state of going out.
When detection switch disconnects, all magnetic valves are off, detection fuel tank and its top in detecting system Air be in closed state, alarm lamp goes out;
When detection switch closes, liquid level sensor signal is detected first, is calculated by controller, judges detection fuel tank In fluid amount whether in allowed limits.
If 1) fluid amount is less in detection fuel tank, judge that each detection is with oil tank liquid level according to liquid level sensor signal The no lower limit less than allowed band;If liquid level is less than the lower limit of allowed band, warning light is bright;Now, detection oil The solenoid closure of box top, detection top of oil-tank and air are penetrated, while open the magnetic valve at oil inlet, ensure inspection Survey is in into oil condition with fuel tank, when fluid amount reaches in tolerance zone, is closed at magnetic valve oil inlet, termination detection oil Case oil-feed, warning light go out.
If 2) oily hypervolia in detection fuel tank, judge that each detection is with oil tank liquid level according to liquid level sensor signal The no upper limit more than allowed band;If liquid level exceedes the upper limit of allowed band, warning light is bright;Now, detection oil The solenoid closure of box top, detection top of oil-tank and air are penetrated, while open the magnetic valve at oil-out, ensure inspection Survey fuel tank is in state of draining the oil, and when fluid amount reaches in tolerance zone, closes magnetic valve at oil-out, termination detection oil Case is drained the oil, and warning light goes out.
For liquid level sensor, when the detection liquid level that liquid level sensor be present is too high, more than the scope of permission, this Times Alert signal lamp is bright;When each liquid level sensor detects liquid level all in allowed band, warning light goes out.
Body gesture is that controller is obtained by liquid level sensor signal of change.When body gesture is in allowed band, Warning light goes out.When body gesture exceedes in allowed band, warning light is bright.
The body gesture detecting system, vehicle stationary state under body posture can be not only detected, it is low also to can detect vehicle Speed body gesture when being travelled on complex road surface.The system can be applied to different type vehicle, reduce design and processing cost.
Beneficial effects of the present invention:
Body gesture, detection fuel tank are calculated with the liquid level of the liquid level sensor acquisition in fuel tank by detection In fluid can supplement and discharge, the magnetic valve of detection top of oil-tank can prevent the fluid in detection fuel tank from overflowing, together When dust cover prevent dust in air from entering detecting system.
