Wireless inclination sensor based on radio frequency identification and wheelchair with rollover detection function

Abstract

The invention belongs to the field of antenna technology and wireless communication, and discloses a wireless inclination sensor based on radio frequency identification, which is composed of a substrate, two antenna main bodies, a ball type inclination switch and two RFID chips, the single-side inclination angle of the ball type inclination switch reaches a critical value, the two pins on the side are in a conduction state, the antenna main body structures are communicated, the electronic product code of the RFID chip can be read by the RFID reader. The inclination condition of the corresponding sensor and whether the wheelchair rolls over or not can be judged according to the condition that the code is read by the RFID reader. The wireless inclination sensor based on radio frequency identification not only can monitor rollover, but also has the advantages of being simple in structure, low in cost, convenient to use, long in working time, long in working distance, high in adaptability and the like, thereby having wide application value and market potential, and the method is expected to assist in constructing an intelligent health monitoring and protecting system for community old-age care.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, in particular to a wireless tilt sensor based on radio frequency identification and a wheelchair with rollover detection. Background technique [0002] The world's population is aging rapidly due to longer life spans and lower birth rates. From 2000 to 2050, the proportion of the population over the age of 60 will double, from 11% to 22%. At the same time, the absolute number of people over 60 is projected to increase from 605 million to 2 billion. The healthcare needs of the elderly will be acute in the coming decades. However, the shortage of medical staff has become a serious social problem in many countries, and this problem is getting worse as the population ages. In order to solve the health problems of the elderly, smart medical devices are highly expected by the government, market, researchers and the public. Wheelchairs are commonly used medical equipment ...
