The dynamic weighing and measuring system of the electric shovel used in the open-pit mine is designed to measure the mineral weight of the electric shovel in real time so as to improve the efficiency of mining,loading and transportation in the open-pit mine.Through the sensor network composed of angular displacement sensor,linear displacement sensor and force sensor,the data information of angle,tension and linear displacement of electric shovel used in open-pit mine is collected and transmitted to the signal processing module.The signal collected by the sensor is reasonably amplified and denoised by the signal preprocessing circuit.After the data is converted by A/D,combined with the angular and linear displacement data,the AT89C52 single-chip microcomputer conversion chip is triggered to read out the dynamic weighing measurement data.And the data is displayed in the LCD display screen in the corresponding form,and the dynamic weighing data processing is completed through the PC to realize the functions of measurement data display,limit alarm,personalized query and so on.The experimental results show that the system can realize the dynamic weighing and measurement of electric shovel in open-pit mine,and the energy consumption is low.When it is applied to the mining,loading and transportation industry of open-pit mine,the efficiency of mining,loading and transportation can be improved.
