When the dynamic and static steady system of this vehicle was used for the weight of kinetic measurement vehicle, the quantity of described weighing device was two, and the front and back wheel of vehicle to be measured is successively by described weighing device.When the dynamic and static steady system of this vehicle was used for the weight of static measurement vehicle, the quantity of described weighing device was the twice of quantity of the wheel shaft of vehicle to be measured, and stationary vehicle to be measured is on weighing device.
The midline of described access bridge upper surface embeds the vehicle pass-through sign.
Described weighing platform lower end offers the second mounting groove, and described pressure transducer top is fixedly installed in the second mounting groove.
Described data transmitting module is data line, and this data line is delivered to data processing module with the information of A/D converter.
Described data transmitting module comprise radio transmitters, with the wireless receiver of radio transmitters coupling; Described radio transmitters and A/D converter are electrical connected, and described wireless receiver and data processing module are electrical connected; Described radio transmitters is placed in the first mounting groove.
The quantity of described pressure transducer is 2~8, adopts a plurality of pressure transducers can improve the measuring accuracy of system.
The beneficial effects of the utility model are as follows:
1, described pressure transducer is removably installed in the weighing platform lower end, when pressure transducer breaks down, and can be conveniently replaceable to its maintenance.
2, the dynamic and static weighing system of this vehicle is simple in structure, can be used for the weight of kinetic measurement vehicle, and weight that also can the static measurement vehicle is easy to use.
