Ultrasonic wave and wireless-based jointed location method

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...

Problems solved by technology

However, the existing technologies have many disadvantages: as in the Chinese patent CN201010609587.8, the ultrasonic positioning based on the network environment is used. Although multiple targets can be located, the cost is relatively high due to the large number of installed devices.

Another example is that although only ultrasonic waves are used in Chinese patent CN200710026504.0, the cost is low, but the installation is more complicated, and four receiving devices need to be placed in four positions of the area to be positioned.
