Problems solved by technology

[0002] In the field of safety assurance in domestic high-risk places, there is already a system for collecting and transmitting the vital sign parameters and environmental parameters of high-risk places such as firefighters, but there is no system using wireless sensing technology, or even if it exists, the collection accuracy and freedom The networking is not ideal, and there is no anchor-free system for positioning personnel in high-risk places on site. Most systems have to pre-deploy nodes on site in advance, which loses the practicability of the system.

Embodiment Construction

[0023] As shown in the figure, in the system of the present invention,

[0024] 1. The watch module, including two wrist devices, collects pulse and heart rate data through skin contact electrodes and preprocesses them; short-range (ZIGBEE) receives data from other components and transmits it remotely (3G);

[0025] 2. The helmet module includes an additional helmet device, which collects the movement trajectory through radar, compass, height sensor, and acceleration sensor, and transmits it to the watch after preprocessing and short-range (ZIGBEE);

[0026] 3. The air exhalation module collects air exhalation pressure and ambient temperature through temperature and pressure sensors and transmits them to the watch in a short distance (ZIGBEE);

[0027] 4. The PDA module, including a handheld PDA device, obtains the movement trajectory of the designated personnel and the movement trajectory of the holder from the command center module, and completes the search function;

Abstract

The invention relates to a high-risk safety guaranteeing system of a digital wireless sensor network, and the high-risk place safety guarantee system is used for guaranteeing safety of firefighters, relief workers and the like in the high-risk places such as fire scenes and mine accident sites. The system comprises a wristwatch module, a helmet module, an air breathing module, a control centre module and a handheld PDA (personal digital assistant) module. According to the invention, the vital signs of people in the high-risk place and the field environment are monitored in real time with the IOT (Internet of things) technology, the real-time tracking and positioning of people in the high-risk place are realized, the field command and scheduling in the high-risk place are accomplished, and the life safety of the people is guaranteed.
