摘要

针对井下环境温湿度监测存在温度漂移、不精确、传输损耗大等问题，提出了基于TMS320LF2812(DSP)的井下温湿度监测及光纤通信传输系统，通过对数字温度传感器的控制，实现井下温湿度监测与光纤通信传输。系统采用RS232串行通信，通过光通信上传数据。实际测试结果表明，该系统工作稳定，温度和湿度的测量精度可达0.1% rh和1%RH。可实现可靠的数据传输。

Research on Temperature and Humidity Monitoring under Mine Based on Optical Fiber Communication System

For the problem of temperature drift, inexact and great transmission loss of the monitoring of environment temperature and humidity under the mine, this paper proposes the temperature and humidity monitoring and optical fiber communication transmission system under the mine based on TMS320LF2812(DSP) by controlling the digital temperature sensor. The system adopts RS232 serial communication, uploads data by optical communication. Data are dealed with by host computer to improve the speed and capability of system .The actual test results show that the system can work stably ,the measuring accuracy of temperature and humidity is up to 0.1¿ and 1%RH. It can realize reliable data transmission.
