4-20mA signals that square is converted to standard by AD conversion module are used as the input of controller, then according to presetting number
Learn model to be calculated, the data after calculating use different lamps respectively compared with presetting alarming value, according to comparative result
Have color to represent, it is possible to when causing danger, dangerous play signal can be cut off, so as to ensure workbench personnel, set
Standby and vehicle safety.
The beneficial effects of the utility model are as follows：
1st, the utility model can carry out the torque or load in real time on detection bridge detection vehicle working platform by bearing pin
The numerical value of power, the result for the calculating that bearing pin data pass through controller are compared with setup parameter, can grasp exactly current
Real load situation.
2nd, the utility model causes the tilting moment of vehicle excessive on workbench it is possible to prevente effectively from answering because load is excessive
And caused vehicle unstable phenomenon, by bridge detection vehicle working platform weighing device, provide at different loads not
Same signal, so as to ensure personnel on bridge detection vehicle working platform, equipment and the safety of vehicle.
