Fire detection search and rescue system and method based on millimeter waves

Abstract

The invention discloses a fire detection search and rescue system and method based on millimeter waves. The system comprises an environment acquisition device, a millimeter wave detector, a wireless transmitter and a monitoring terminal. The environment acquisition device is used for sending the acquired environment information to the wireless transmitter; the millimeter wave detector is used forcarrying out all-weather scanning on the environment to be detected so as to obtain characteristics and position information of a life body in the environment to be detected, and sending the characteristics and the position information of the life body to the wireless transmitter; the wireless transmitter reports all the collected information to the monitoring terminal through millimeter waves sothat the monitoring terminal stores the characteristics and position information of the life body; the monitoring terminal searches and rescues the life body based on the change by continuously comparing the change of the life body characteristics and the position information detected by the millimeter waves before and when the fire occurs. According to the system, accurate technical support can be provided in case of a fire, so that firefighters can accurately and quickly rescue trapped persons.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a millimeter wave-based fire detection search and rescue system and method. Background technique [0002] Fire usually causes great loss to people's lives and property, and fire detectors generally can only simply detect the environmental conditions, and cannot provide effective disaster information when the fire becomes larger. [0003] For example, when a fire breaks out in a building, the infrared sensor is easily disturbed by the heat source, resulting in poor passive infrared penetration, and the infrared radiation of the human body is easily blocked and difficult to be received by the detector. When the ambient temperature is close to the human body temperature, the infrared sensor or, install image transmission equipment in places that need to be monitored to obtain video information, and use algorithms to identify human targets in the video information. However, th...

Problems solved by technology

[0002] Fire usually causes heavy losses to people's lives and properties. Fire detectors can only simply detect environmental conditions, and cannot provide effective disaster information when the fire becomes larger.

[0003] For example, when a fire breaks out in a building, the infrared sensor is easily disturbed by the heat source, resulting in poor passive infrared penetration, and the infrared radiation of the human body is easily blocked and difficult to be received by the detector. When the ambient temperature is close to the human body temperature, the infrared sensor or, install image transmission equipment in places that need to be monitored to obtain video information, and use algorithms to identify human targets in the video information. However, the fire scene environment is often very complicated, and it is difficult to obtain video through the video system. Information to identify human targets; and at present, 3FG / 4G or Bluetooth technology is usually used to transmit the fire information obtained by the detector, the transmission is slow, and it is very likely that the collected information cannot be reported to the monitoring terminal in time

[0004] Rescuing trapped people after a fire is the most important link, but the existing detection and search and rescue system has the above defects, which cannot determine the location and vital signs of trapped people in the shortest time, resulting in missing the best rescue opportunity and causing loss of life
