Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the architecture of the system includes one reference point 1 and multiple points to be positioned, and only two points to be positioned 21 and 22 are shown in the figure. The reference point 1 periodically sends ultrasonic signals and radio frequency signals, and the points to be located 21 and 22 receive ultrasonic signals and radio frequency signals continuously.

[0019] The schematic diagram of the reference point principle is as follows figure 2 As shown, it includes a radio frequency transmitting module 11 , multiple ultrasonic transmitting modules 12 , 13 , 14 and a timing module 15 . Adjacent ultrasonic modules form a certain angle, which can completely cover the area where the point to be located is located. The timing module controls the periodic signal transmission of the wireless radio frequency module and the ultrason...

Abstract

The invention discloses an ultrasonic wave and wireless-based jointed location method, relating to a location method. One datum point and a plurality of points to be located are included, wherein the datum point comprises an ultrasonic wave transmitting module, a wireless ratio transmitting module and a timing module; and each point to be located comprises an ultrasonic wave receiving module, a wireless radio receiving module and a main processing module for processing an ultrasonic wave and a wireless radio signal. The datum point periodically simultaneously transmits an ultrasonic wave signal and a wireless radio signal, the points to be located continuously receive the wireless radio signal; when the wireless radio signal is received, a corresponding timer is started and stops timing until the ultrasonic wave signal is received, and the main processing module processes the distance from each probe to the datum point, and figures a position of each point to be located, thus location is realized. The ultrasonic wave and wireless-based jointed location method has the advantages of simple structure, convenience for installation, low cost, multi-target location, strong interference and the like, and is very suitable for fields of intelligent location of families and enterprises.

Description

technical field [0001] The invention relates to a positioning method, in particular to a combined positioning method based on ultrasonic waves and wireless. Background technique [0002] Today's society is becoming more and more intelligent, and people's lives are gradually becoming intelligent, such as robots that take care of children, smart wheelchairs, and smart cleaning vehicles. Although these intelligent products are very convenient, they all need to be charged. Whether these machines can locate the location of the charger, automatically find the charger and charge it, this involves the problem of positioning. The ultrasonic positioning technology of the present invention can solve this type of problem. [0003] Currently common indoor positioning technologies include infrared technology, image recognition technology and ultrasonic technology. But the existing technology has many disadvantages: for example, the ultrasonic positioning based on the network environment...
