Description
Technical Field
The invention relates to the technical field of vehicle-mounted bearing, in particular to an intelligent vehicle-mounted weighing management system.
Background
In order to implement the relevant laws and regulations such as strict prohibition on overrun and overload, foreign scholars began to research the vehicle overload monitoring technology in the later 50 th of the 20 th century, and mature products including static whole vehicle measurement of a static weighing system and dynamic axle load detection of a dynamic weighing system were basically formed in the 90 th of the 20 th century. Dynamic axle weight sensing is also known as a weighbridge, a weighbridge-type force-transmitting induction electromechanical weighing system.
Weighing systems that are common today are static weighing systems, dynamic weighing systems and portable weighing apparatuses. The static weighing system is accurate in measurement, but is limited by space and time, so that the working efficiency is low; the weighing equipment of the dynamic weighing system is separated from the vehicle, so that the vehicle state cannot be monitored in real time; the portable weighing instrument needs to be placed according to the wheel spacing at every time, and the portable weighing instrument is troublesome to use. The three technologies have disadvantages, and along with the vigorous development of the logistics transportation industry, the prior art is more and more difficult to meet the market demand.
Many enterprises also stay in the traditional pure manual weighing mode, as shown in fig. 1, the vehicle needs to be weighed after being unloaded to the weighbridge, and then needs to be weighed again after being loaded with goods, and various information is manually input. Two or three weighers are required to be matched with one weighbridge, the required time of each weighing vehicle is different, the drivers need to get off the vehicle and communicate with the weighers after weighing, the weight of the vehicles and the unit information of the drivers are recorded, and the weighers also need to check whether the vehicles are completely weighed. The whole weighing process takes 2-3 minutes from the beginning to the end.
Also some enterprises have used dynamic vehicle-mounted weighing system now, as shown in fig. 2, be a dynamic weighing system's data acquisition panel, dynamic weighing system is through the strain gauge sensor data collection of many pieces of installations in the vehicle bottom to whether quick judgement has the problem of overload. The data terminal is driven along with the vehicle, namely, the vehicle is weighed in real time when the vehicle carries goods, the vehicle is monitored in real time when the vehicle drives away from a departure place and arrives at a destination, and the weight of the goods loaded and unloaded can be reflected in real time at the background when, where and where. The whole process is completed by a computer, no manual operation is involved, the faults can be reduced, and the fraud can be reduced.
The traditional pure manual weighing mode can only realize small-range spot inspection, so that a large part of freight vehicles escape from inspection and continue to be overloaded by ways of bypassing and the like, and the market competition is unfair; and various information is manually input, so that the labor cost is high, the working efficiency is low, the normal traffic of vehicles can be interfered, and the traffic is blocked.
The existing dynamic weighing system is characterized in that a plurality of sensors are arranged on axles or stressed key points, and the load of the whole truck is calculated by monitoring the deformation of each axle and each stressed key point.
