FIELD: fire-prevention facilities.SUBSTANCE: invention relates to the field of instrumentation and can be used in detection of fires in forestry. Forest fire detection system comprises a unit of radio transmitter, a unit of radio receiver. Forest fire detection system is also provided with sensors of temperature and concentration of carbon dioxide, units of electric power supply the carbon dioxide concentration sensors, and a radio transmission device, a unit of switching on and off the electric power supply, the data conversion unit of the temperature and concentration of carbon dioxide and transferring them to the radio transmitter, the power control unit of the radio transmitter, the data processing unit of the temperature and concentration of carbon dioxide. Units of sensors of temperature and carbon dioxide, the electrical power unit of sensors, the unit of switching on and off the electric power supply, the unit of the radio transmitter, the power control unit of the radio transmitter are located directly in the zone of possible fire emergence. The unit of radio receiver is located at a distance in the radio range area of the radio transmitter. The electrical power unit is connected to the carbon dioxide concentration sensor and a unit of radio transmitter, the a unit of switching on and off the electric power supply is connected to the electrical power unit and the temperature sensor, the sensors of temperature and carbon dioxide concentration are connected with the data conversion unit of the temperature and concentration of carbon dioxide and transferring them to the radio transmitter, the power control unit of the radio transmitter is connected to the carbon dioxide concentration sensors and the unit of radio transmitter, the unit of radio transmitter is connected by the radio channel with the unit of radio receiver, the unit of radio receiver is connected to the data processing unit of the temperature and concentration of carbon dioxide, the data processing unit of the temperature and concentration of carbon dioxide is connected to the communication unit with the receiving operators.EFFECT: early local detection of emergence of forest fire and prompt non-contact notification about its emergence by the receiving operators.1 dwg |
