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

[0022] As shown in the figure, in the system of the present invention,

[0023] 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 parts and transmits them remotely (3G);

[0024] 2. The helmet module includes a helmet attachment device, which collects the motion trajectory through radar, compass, height sensor, and acceleration sensor, and transmits it to the watch after pre-processing the short-range (ZIGBEE);

[0025] 3. The air breathing module collects air pressure and ambient temperature through temperature and pressure sensors and transmits them to the watch in a short distance (ZIGBEE);

[0026] 4. The PDA module, including a handheld PDA device, obtains the movement trajectory of the designated person and the holder from the command center module to complete the search function;

[0027] 5. The command center module includes a command center sys...

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, andthe life safety of the people is guaranteed.

Description

Technical field [0001] The invention relates to a digital wireless sensor network safety guarantee system for high-risk places such as fires, mine accident scenes, etc., for safety guarantees for firefighters, disaster relief personnel, etc. Background technique [0002] At present, in the field of safety protection in high-risk places in China, there have been systems for collecting and transmitting vital signs and environmental parameters in high-risk places such as firefighters. However, the system using wireless sensing technology does not currently have or even if it exists, but the acquisition accuracy and freedom The networking is not ideal, and there is no system for anchor-free positioning of personnel in high-risk locations on the spot. Most systems require pre-arrangement of nodes on the spot, which loses the practicality of the system. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a digital wireless sensor n...
