Meter shafting all based on track traffic

The utility model provides a meter shafting all based on track traffic, including connecting the switch module between power module and signal amplification module, pass through the power supply that switch module control signal enlargies the module according to the external control signal, thereby cut off or the connection signal enlargies the signal connection between module and the meter operation module, and the signal connection between signal amplification module and the output module, be not it seems that meter axle sensor is cut off to the conventional art that kind is connected with the physics between the meter arithmetic unit, the problem of with high costs with the construction degree of difficulty big is solved. Above -mentioned meter shafting all based on track traffic is still including the switch detection module who is used for the detection switch module whether normally to work, avoid since the switch module take place unusual and lead to cut off the inefficacy, improve factor of safety.
