Temperature Monitoring System of Ground Coal Pile Based on Single Chip Microcomputer

摘要

The temperature of the coal heap is one of the reasons that cause spontaneous combustion of coal. Therefore, it has great significance to monitor the temperature of the coal heap on the ground timely.In this paper, we design a temperature monitoring system for the coal heap on the ground based on the single chip.We bury several digital temperature sensors in the coal heap and collect data through the AT89C52 single chip, and then use the up -computer software of the central computer to process them uniformly. Finally it is successful to detect the curve of the temperature of the coal heap in real time, and display the curve of temperature variation on the LCD screen. The system will send out warning messages automatically when it detect the anomalous temperature, and send warning messages to the monitor terminal timely though the GPRS network. Then it will take relevant measures to prevent the coal serf - ignition from occurring.
