Based On The Atmega16 Mining Hydrological Intelligent Monitoring System Design

Water hazards is one of the five coal-mine natural disasters. Since the founding of China, hundreds of times coal-mine water hazards accidents have taken place in our country. A number of coal-mine water hazards accidents proved that water hazards was a serious threat to the safety of the coal-mine production and the miners'lives. Therefore, effective prevention and treatment of coal-mine water hazards has an important practical significance. "Coal-Mine Safety Regulations" (2004 edition) Section 252 has a clear requirement that the coal-mine with water hazards threaten need for sound hydrological monitoring systems. The traditional manual measurement method which measurement accuracy is low and real-time performance is poor and labor-intensive and more costly and low efficiency, can not detect the unusual timely. Therefore, it can not take measures timely to prevent disasters. In this situation, the coal-mine hydrological intelligent monitoring system produced and gradually developed.This paper presents a method for designing the coal-mine hydrological intelligent monitoring system based ATmegal6. The system can monitor the drilling water level and temperature and other parameters all day, and store the information on the monitoring computer. Once the danger appears,it can immediately alarm,and people all can take measures to ensure the safety of the mine and the miners. Therefore, the coal-mine hydrological intelligent monitoring system has an important role and practical significance for prevention and treatment of mine water hazards.The coal-mine hydrological Intelligent Monitoring System's work principles as follows: Firstly, the ATmega16 collects datas from the sensor HG500 and DS18B20, then passes the datas through the serial port to the GSM module TC35i. Secondly, the TC35i passes the datas in the form of the short message via GSM network to the monitoring and warning device. Finally, the monitoring and warning device sends the datas to the host computer through the computer serial port, and the host computer's hydrological monitoring software receives the datas and stores them.This paper presents the design processes of the coal-mine hydrological intelligent monitoring system's hardware and software. The key is the design processes of water temperature monitoring system's hardware and software. This is also my responsibility in the project's work. Water temperature monitoring system's hardware design include the DS18B20 with ATmegal6 interface circuit design and the TC35i and ATmegal6 interface circuit design. The software design mainly used the C language to configurate the ATmegal6's related register, and completed the collection of DS18B20's temperature datas, and sent the datas to the host computer through the serial port. This article also briefly introduced the design processes of the host computer software for the hydrological monitoring system. Finally, the article also gives a number of directions to improve the hydrological monitoring system.
