Application of greedy algorithm in dynamic weighing system of electric shovel in open-pit

In order to prolong the life time of data transmission network and improve the effect of dynamic weighing，this paper studies the greedy algorithm to design the dynamic weighing system of electric shovel in open-pit coal mine，collects dynamic weighing data of electric shovel in open-pit coal mine through force sensor and angle sensor.The internal noise of the collected data is filtered by the signal processing circuit，and the processed data is transmitted to the wireless communication module in the way of output interface.The approximate greedy algorithm is used to optimize the data transmission distance and prolong the network life time.The data are collected by the force sensor and angle sensor controlled by single-chip microcomputer，and the limit alarm is realized according to the processing result of PC.The PC is used to process the data received by the single-chip microcomputer，and the dynamic weighing data of the electric shovel are obtained and displayed on the LCD display.The system can effectively collect the stress value when the electric shovel rotates.When the number of network rings is different，the network life time of data transmission is longer，the ratio is higher，and the effect of data transmission is better.The system can accurately weigh dynamically and effectively present the results of dynamic weighing.
