Magnetic field value measuring device and magnetic field value measuring method

Abstract

The invention discloses a magnetic field value measuring device and a magnetic field value measuring method. The magnetic field value measuring device comprises a first Hall sensor, a magnet and a second Hall sensor. The first Hall sensor and the second Hall sensor are connected with a processing unit in parallel, and one end of the processing unit is connected with an I / O interface; one end of the processing unit is connected with a first laser sensor and a second laser sensor in parallel, the first Hall sensor, the magnet and the second Hall sensor are used for measuring the distance value between the upper portion and the lower portion of the chassis, and one end of the processing unit is electrically connected with a result feedback module; the result feedback module is electrically connected with a display module and used for displaying a specific magnetic field value and monitoring the magnetic field value of the vehicle in real time, the specific magnetic field value d can be calculated through a formula according to the voltage values of the first Hall sensor and the second Hall sensor and the magnetic field value of the magnet, and the purpose of real-time monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of magnetic field value measurement, in particular to a magnetic field value measurement device and a magnetic field value measurement method. Background technique [0002] At present, the overload supervision of trucks is mainly in the charge of the road management department. The main method is to check roads and require the cooperation of weighbridges. They are usually installed at the entrances and exits of expressways, which greatly limits the control of trucks. This monitoring method cannot achieve flexible and real-time monitoring of the loading capacity of the truck, and its efficiency is extremely low, and it is easy to cause traffic accidents due to overloading. [0003] In the prior art, there is no method for estimating the weight of a truck through the magnetic field value. Therefore, we propose a magnetic field value measuring device and a magnetic field value measuring method. Contents of th...
