Action assisting and remote monitoring system for blind people

Abstract

The invention discloses an action assisting and remote monitoring system for blind people. The system comprises a portable device, a ZigBee networking module and an intelligent portable terminal, wherein the portable device includes a processor, a ranging module, a temperature measuring module, a gyroscope module, a prompt module and a communication module; the communication module includes a ZigBee module and a GSM / GPRS module; the ZigBee module and the ZigBee networking module perform wireless communication through an ad hoc network; the GSM / GPRS module and the intelligent portable terminal are connected by a GSM network. The system acquires obstacle information by the portable device and combines the ZigBee networking module to acquire the positioning and navigation information, so as to achieve action assistance; and the portable device sends the location information to the intelligent portable terminal to achieve the remote monitoring. The action assisting and remote monitoring system for blind people is simple to assemble, high in expansibility and convenient to use.

Description

technical field [0001] The invention relates to movement assistance and monitoring technology, in particular to a blind movement assistance and remote monitoring system. Background technique [0002] China is the country with the largest number of blind people in the world. There are about 450,000 new blind people every year. Visually impaired or totally blind people account for about 1 / 5 of the total number of blind people in the world. [0003] With the improvement of living standards, blind people's desire to know more about the world and better integrate into society is also growing stronger. Vision is the most intuitive way to understand the world, but due to physical defects, blind people cannot intuitively obtain external information through vision, which makes them inconvenient in study, life and work. [0004] With the continuous improvement of the level of social civilization, blind people are getting more and more attention from the society. The ...
