Abstract

The utility model relates to an intelligent positioning alarm crutch. The intelligent positioning alarm crutch comprises a GPS (global positioning system) positioning module, a master control module, a transmission module and an angle sensing module, and is characterized in that the master control module is respectively connected with the GPS positioning module, the transmission module and the angle sensing module. The GPS positioning module is utilized for determining the position of a user at any time, and the master control module is used for comparing the current longitude and latitude information with the path information pre-stored in the crutch and giving prompt information to help the user return to a preset range if the current longitude and latitude information exceeds the preset range. If the current longitude and latitude information exceeds a certain range, a short message can be sent to a guardian through the transmission module for alarming, and the content of help information contains current positioning information time and the like. The angle sensing module is utilized for sensing whether the crutch is inclined or not, and if the crutch is inclined with an old person who falls down over a certain period of time, the short message can be sent to the guardian for alarming and seeking help from the guardian, and the short message can be sent to the intelligent crutch at any time for inquiring the current position.

Description

Intelligence locating alarming crutch

Technical field

This utility model relates to a kind of crutch, especially intelligent locating alarming crutch.

Background technology

Along with some specific demands of the raising old people of social civilization level, blind person, amentia personage are worth further paying close attention to.Often find that the old people is because advanced in age, hypomnesis is not remembered own home's position, do not remember yet and children family between the road, dare not go out and can not walk up and down.Amentia personage disappears without a trace after leaving guardian's (relatives, nursing house, monitor center etc.), is difficult to seek; The blind person often departs from projected route etc. when the unit of going or trip.

Summary of the invention

In view of above reason, this utility model integrated application GPS location, GMS the fabrication techniques such as GPRS transmission, angular surveying a kind of intelligent locating alarming crutch.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of intelligent locating alarming crutch, comprise GPS locating module, main control module, transport module, angle sensor module, it is characterized in that main control module is connected with GPS locating module, transport module, angle sensor module respectively.The GPS locating module that utilizes is determined the position of user at any time, main control module will current latitude and longitude information and pre-stored routing information in crutch compare, get back to preset range if exceed preset range then provide information help user.Send short message alarm by transport module to the guardian if exceed certain limit, the help information content comprises the current locating information time etc.Whether utilize angle sensor module perception crutch to skew, if crutch founders above certain hour with the old man, send short message alarm to the guardian, the guardian that seeks help can send short messages to Intelligent crutch at any time and inquire about the current location guardian.

The beneficial effects of the utility model are, help user to get back to scope or the path of setting, when crutch skews above certain hour, send emergency and locating information from the trend guardian, trip to special population can provide effective help, has higher practicality.
