Accurate positioning system with vital sign monitoring function

Abstract

The invention provides an accurate positioning system with a vital sign monitoring function. Hook-and-loop tapes are distributed on two sides of a silicon band fixed at the position of a wrist of a user, air bags are assembled on two sides of an end surface of one side of the silicon band, a flexible circuit board is assembled between the two air bags, a heart rate sensor for monitoring a heart rate is mounted on the rear side of each air bag, and a body temperature sensor for monitoring the body temperature of the user is arranged on the front side of each air bag. By addition of the heart rate sensors, vital signs are monitored. By the design, project design and deployment of emergency rescue are greatly facilitated; by the body temperature sensors, the body temperature of the user can be monitored in real time; with the aid of a wireless communication module, data are transmitted to external receiving equipment; a recognition card has low power consumption, and thus the endurance ofthe recognition card is prolonged; and operations of a first card reader, a second card reader and the recognition card are not affected by a working environment, thus, positioning accuracy is greatly improved, and the structure is simple and reliable.

Description

technical field [0001] The invention is an accurate positioning system with the function of monitoring vital signs, which belongs to the field of mining positioning equipment. Background technique [0002] In the existing technology, according to the requirements of the State Administration of Work Safety and the State Bureau of Coal Mine Safety Supervision "Notice on the Construction and Improvement of the "Six Major Systems" for Underground Coal Mine Safety and Avoidance" (An Jian Zong Mei Xiang [2010] No. 146) and other documents, the construction Improve the underground personnel positioning system, and do a good job in system maintenance and upgrading to ensure the safe and reliable operation of the system, as one of the necessary conditions for issuing (modifying, extending) the coal mine safety production license. The underground structure of the mine is complex, and there are many and scattered underground workers. In order to ensure the safety of underground personn...

AI Technical Summary

Problems solved by technology

The intensity of electromagnetic waves has a strong dependence on the working environment, resulting in poor positioning accuracy and a large degree of uncertainty; ultra-wideband technology is calculated by using the time-of-flight difference, and the positioning accuracy can reach a high level, but it also has the following disadvantages: 1. It requires at least 3 working base stations for positioning, which is not suitable for mine tunnel positioning; second, the ultra-wideband operating frequency is easy to interfere with other equipment; third, the power consumption is high, and the battery-powered portable identification card cannot meet the requirements of the mine.
