Intelligent fire safety monitoring system and monitoring method based on millimeter-wave radar

Abstract

The invention discloses an intelligent fire safety monitoring system and monitoring method based on millimeter-wave radar. The monitoring system comprises an intelligent fire hazard early warning andrescue auxiliary module, a wireless transmit-receive device, a cloud server and a control terminal. The intelligent fire hazard early warning and rescue auxiliary module comprises a millimeter wave radar detection tracking device, a smoke detection device, a temperature detection device, a water sprinkling controller, a power supply device and an alarm device. When a fire occurs, the millimeter-wave radar detection tracking device detects user position information and state information and sends the information to the cloud server through the wireless transceiver; and the cloud server recordsthe information, judges the condition of field personnel and sends the information to the control terminal, and the control terminal can display the number of people indoors, the fire occurrence position, the personnel motion trail and the personnel health state. The system can effectively monitor the number and distribution conditions of indoor personnel when a fire occurs, tracks the motion trails of the indoor personnel, checks the respiratory signs of the indoor personnel, and does not involve the personal privacy of a user.

Description

technical field [0001] The invention belongs to the field of indoor positioning and fire protection, and in particular relates to an intelligent fire safety monitoring system and monitoring method based on millimeter wave radar. Background technique [0002] The frequency range of millimeter wave is between microwave and infrared, and millimeter wave radar has some advantages of microwave radar and photoelectric radar. At the same time, the millimeter-wave radar has the characteristics of small size, light weight, and strong anti-interference ability. In the event of a fire, the millimeter-wave radar is extremely capable of working in high-temperature and smoky environments. Therefore, the millimeter-wave radar can well count the number of people in the house and the respiratory signs of the people in the room, which is beneficial to help firefighters carry out Rescue work. [0003] So far, the technology of indoor intelligent monitoring is still not mature enough. Becaus...

AI Technical Summary

Problems solved by technology

However, people often cannot accurately grasp the specific occurrence of the fire in the process of calling the police, so the firefighting unit cannot accurately extinguish the fire according to the fire situation.

In addition, if there is no one on duty at the time of the fire, it will often cause the fire to spread and cause serious losses.
