Weighing device for goods on freight cars

Abstract

The invention discloses a weighing device for goods on freight cars, comprising at least one weighing component and a processor. The weighing component comprises a weighing sensor (2), an elastic element (3), a bearing board (4) and a bearing frame (7). The elastic element (3) is loaded between the bearing board (4) and the bearing frame (7). The weighing sensor (2) comprises a sensing part (2.1),a measuring part (2.2) and a measuring circuit. The sensing part (2.1) is relatively fixed on the bearing board (4). The measuring part (2.2) is relatively fixed on the bearing frame (7). The longitudinal displacement of the bearing plate (4) drives the sensing part (2.1) to produce relative displacement relative to the measuring part (2.2). The signal output end of the measuring circuit is connected with the sampling signal input end of the processor. The weighing sensor is directly installed on a movable base. The weighing sensor can be directly placed under the goods in a car when needed,and can be directly taken away after use. The assembly and disassembly work and the cost for assembly and disassembly are avoided. The weighing device has a simple structure, and can realize remote monitoring.

Description

technical field [0001] The invention relates to the field of weighing, in particular to a weighing device for goods in a truck. Background technique [0002] During the transportation of goods by truck, due to vibration or theft, the goods of the owner are often lost, so it is necessary to detect the goods in a timely manner. The existing method of weighing goods is mainly to install an angle sensor on the suspension of the truck. The weight method carries out the weighing measurement of goods, but the angle sensor is difficult to install and remove. Other existing load cells need to be installed in the auto repair shop, which is expensive to install and disassemble, and because the truck is hired temporarily, it needs to be reinstalled and disassembled every time it is used, which is costly. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a weighing device for goods in a truck. [0004] ...
