Research And Design Of Forest Fire Monitoring Technology Based On MSP430

Paper based on in-depth study of forest fire monitoring technology as well as the MSP430chip application technology, developed a low-power monitoring system for forest fire. for the characteristics of MSP430Chips, research and build the hardware and software functional modules, the corresponding optimal design. Build an experimental model, in the experiment to take the appropriate measures to reduce the interference of the environment on the sensor, the experimental data obtained verify the accuracy and feasibility of the system. And designed a data storage and management.Automatically using solar power system design, GPRS wireless communications, can be placed in the wild, without human duty. Wind speed, wind direction data acquisition using ultrasonic sensor to replace the traditional wind vane cup, in practical applications can eliminate mechanical wear and tear, reduces environmental interference, improve data collection accuracy. Temperature measurement using a new temperature sensor LM-Pt100, and used in circuit design, and two quad analog switch4052to prevent temperature drift of the resistance, to ensure the accuracy of temperature data, the temperature sensor’s power supply for the constant current source, the microcontroller pin, and by the divider, comparator, and a negative feedback circuit to ensure constant pressure to provide constant current. Humidity sensors used in test models for the Finnish HMP45D, has been tried in the country for many years, because of its relatively stable performance has been a large number of automatic weather stations using this sensor. Rainfall measured by tipping bucket rain sensor, rainfall can be converted into a pulse count, the collector of this pulse can be measured cumulative rainfall accumulated value.This is designed to clear modular design, various sensors, power, communications, data storage unit highly integrated, and per-minute interval data on forest fire automatic acquisition factor, and through the core components MSP43O appropriate treatment process and storage. The measured and calculated data through CDMA/GPRS wireless network to send to the central station computer data management by computer processing software for the professional on the corresponding data processing, and finally the fire and the fire danger rating forecast release.Paper design data management and delivery methods, data acquisition processor left a RS232C serial interface, you can take the appropriate action series notebook, you can set the data format. This release comes with the Ministry of Forestry on forest fire weather nationwide industry standard level (Linke pass word [1995] No.76) industry standards, listed in detail the line of fire rating and assessment formula, the standard fire insurance rating is the basis on which This calculation is based on the fire danger rating.
