Product Description

Product Description:

    At present, there are several forms of dynamic vehicle weighing in use in China: axle-weight type, curved plate type, quartz type, and vehicle type. The first three are local weighing, that is, by measuring the wheel, axle or axle weight of the vehicle, through the accumulation of the weight of the vehicle, its measurement results in addition to the limitations of the system itself, but also by the vehicle travelling mode, road conditions, and thus the general measurement error is larger, but also prone to frequent drivers that cheating driving caused by a larger error, seriously affecting the road owners or owners of the interests of the vehicle. 
The whole vehicle weighing can fundamentally improve the accuracy of measurement, to eliminate the occurrence of cheating driving behaviour, but the traditional vehicle weighing can only measure one vehicle at a time, which will seriously affect the traffic efficiency of the toll station, and therefore can ensure the necessary measurement accuracy, but does not affect the traffic efficiency of the whole vehicle type dynamic vehicle weighing is very suitable for China's weighing and charging system. 
Our dynamic toll collection system can be operated in two modes, each adapted to different accuracy requirements. There is no need to manually switch between the two modes, the installation of electric barriers that is automatically working in mode 1, without the installation (or close) of electric barriers will automatically work in mode 2.
Mode 1: One car, one pole mode That is, the first car on the scales to complete the measurement (without driving down the scales), open the entrance electric railing, the second car into the second car into the scales, wait for the second car completely into the scales to close the entrance railing, and wait for the first completed payment of fees to drive off the scales to complete the weighing of the second car immediately and can be open to the third car into the. This mode of operation requires another electric barriers or (and) traffic lights at the entrance, the control signal is provided by the control instrument, the efficiency of the passage is basically the same as the continuous follow-up, the measurement accuracy is generally better than 0.5 level.
It should be noted that if the vehicle following the entrance breaks into the weighing platform, the system will automatically process it according to mode 2. 
Mode 2: Continuous Following Mode This mode is basically the same as the normal axle scales, with no restriction on the passage of vehicles, and the weighing instrumentation divides and processes the vehicles entering the platform. The accuracy of the weighing in this mode is slightly lower than in mode 1, depending on the combination of vehicles. In general, a small vehicle following a large moving vehicle may have a large relative error. In contrast, vehicles that enter when the vehicle in front is stationary, or large vehicles that follow small vehicles, can achieve accuracy that is generally comparable to that of Mode 1. Typically up to Class 1. 
The control instrument supports both front mounting and cross booth mounting, the latter being generally more accurate, and also directly supports axle group scales.

Product system components :

 

1. Complete vehicle scales	Specially designed platform with additional axle identification
2. Weighing Controller	This is the brain of the system, made up of several microprocessors, responsible for processing the information of the platform, the axle recogniser (if configured), the vehicle separator, sending the weighing data to the computer, and sending the control signals to the electric barriers (if any)
3. Wheel and axle recogniser	It is used to identify whether the passing axle is single or double wheel, whether it is configured or not is decided by the system demand
4. Vehicle separator	It is used to indicate whether the vehicle is completely on the platform, usually using infrared light curtains, or ground sensing coils or similar equipment can also be used
