Problems solved by technology
The total volume of incoming and outgoing goods traded by a steel factory reaches billions of tons each year. In actual use, the weighing platform is subjected to frequent or even brutal impacts from the outside of the car. Although it is protected by horizontal and vertical unbalanced loads, the weighing platform is unbalanced after being impacted. The protection may not be reset in time, which affects the authenticity of the measured load. The maintenance personnel have not discovered and dealt with it in time, especially at night, when there are few people on duty, there is no time to take care of it. This not only reduces the overbalance efficiency, but also has a huge measurement risk

The invention provides a monitoring device for a gap between a weighing platform of a truck scale and a roadbed. The monitoring device comprises a plurality of eddy current sensors, a gap monitor anda PLC. The eddy current sensor comprises a probe and a front-end processor, the probe is connected with the front-end processor, and the probes of the plurality of eddy current sensors are all arranged on the weighing platform. A plurality of target points are arranged at the end part of the roadbed, each target point corresponds to one probe, and the front-end processor is connected with the gapmonitor and can transmit a gap value measured by the probe to the gap monitor, and the gap monitor is connected with the PLC. The monitoring device can ensure that the angular difference of the weighing platform is eliminated on a reasonable pressed surface, the load is truly measured, the risk of material metering is avoided, and the direct economic loss or associated legal risk is further avoided.
Description
technical field [0001] The invention relates to the technical field of automatic instruments, in particular to a monitoring device for the gap between a weighing platform of a truck scale and a roadbed. Background technique [0002] Digital truck scales are important measuring instruments for bulk cargo vehicle weighing and trade settlement. Commercial and trade measuring instruments belong to the category of compulsory inspection stipulated by the state. After each inspection or debugging, they must pass the verification of the legal metrology verification institution before they are allowed to use. The total volume of incoming and outgoing goods traded by a steel factory reaches billions of tons each year. In actual use, the weighing platform is subjected to frequent or even brutal impacts from the outside of the car. Although it is protected by horizontal and vertical unbalanced loads, the weighing platform is unbalanced after being impacted. The protection may not be res...
