Problems solved by technology

[0003] In the prior art, the parameter management of explosion-proof automobiles on automobile power supply, motor, and electric rubber tires has higher safety requirements than the management of existing automobiles. The existing automobile instruments only display the quality of automobile power supply, motor, and electric rubber tires. For the field of explosion-proof vehicles, changes in the voltage, current, and temperature values ​​of the automotive power supply, motor, and motor controller at any stage will affect the safety of the entire explosion-proof vehicle at work, and drivers of explosion-proof vehicles need to have a comprehensive understanding of the vehicle. Parameters of automobile power supply, motor and electric rubber wheel block
However, the automotive instruments in the prior art not only take a single protective measure when the automotive power supply, motor, and electric rubber tires are affected by voltage, current, and temperature, but also cannot display them in time, so it is not conducive to the drivers in the industrial and mining scene. Maintenance, which in turn leads to a decrease in the service life of explosion-proof vehicles, affecting the safety of the entire industrial and mining implementation

Abstract

The invention discloses a parameter detection and alarm method and system for an explosion-proof automobile. The method comprises the following steps that voltage values, current values and temperature values of a power supply, a motor and a motor controller of the automobile are obtained and uploaded to a whole automobile controller through a CAN network; the vehicle control unit compares the voltage value with a plurality of preset voltage thresholds to obtain a voltage alarm level; the current value is compared with a plurality of preset current thresholds to obtain a current alarm level; the temperature value is compared with a plurality of preset temperature thresholds to obtain a temperature alarm level; and the vehicle control unit controls the instrument to display the alarm levelin real time and send out a corresponding alarm prompt. According to the invention, the vehicle control unit makes corresponding display and alarm prompts according to the voltage alarm level, the temperature alarm level and the temperature alarm level, so that a driver can make corresponding maintenance measures according to the alarm levels, and the safety of the explosion-proof vehicle during operation is improved.

Description

technical field [0001] The invention relates to the technical field of special automobiles, in particular to a method and system for detecting and warning parameters of explosion-proof automobiles. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, cars have entered thousands of households and become one of the main means of transportation for ordinary people's daily travel. It is indispensable, and the main factors affecting the life of the automotive power supply, motor, and electric rubber tire include voltage, current, and temperature. When the voltage, current, and temperature exceed the thresholds specified by the automotive power supply, motor, and electric rubber tire , The life of the motor and the motor controller is a threat. [0003] In the prior art, the parameter management of explosion-proof automobiles on automobile power supply, motor, and electric rubber tires has higher safe...
