Embodiment 1

[0030] Such as figure 1 As shown, a sound radio coordinated positioning device includes a positioning system 1 and a beacon group composed of two beacon units 2, the positioning system and the two beacon units are connected through communication, and the positioning system includes a radio receiving module 11, the first A sound receiving module 12 and a beacon identification module 13 , the beacon unit includes a radio transmitting module 21 , a sound transmitting module 22 and a second sound receiving module 23 .

[0031]When the beacon unit is triggered, the radio signal is transmitted through the radio transmission module, and the sound signal is transmitted through the sound transmission module, wherein the radio signal contains a wireless identification code, and the sound signal contains a voice identification code; the transmission frequency of the radio transmission module is 315MHz or 433MHz or 2.4 GHz; the sound transmitting module is a buzzer or a speaker; the secon...

Embodiment 2

[0046] The quantity of the beacon unit of embodiment 2 is three namely respectively B 0 , B 1 and B 2 , others are identical with embodiment 1.

[0047] The three beacon units are placed in sequence to form a right-handed triangle, with the z-axis facing upwards. Beacon Unit B 0 The location is the coordinate origin, the beacon unit B 1 The position is a point upward on the x-axis, beacon unit B 2 (Y positive side) on the xy plane (beacon plane). If the positioning system is constrained to move on the beacon plane, multiple sets of beacon pairs can be used to perform multiple positioning and combine the results to make the best estimate to improve the accuracy.

[0048] When three beacons are used, the coordinates of the locator in the three-dimensional space are determined according to the distribution of the beacons. Usually the solution coordinates may not be unique, and they are distributed in a mirror image with the plane where the beacon is located. At this time, ...

Abstract

The invention discloses a sound-radio cooperative locating device and method thereof. The device includes a positioning system and a beacon group composed of a plurality of beacon units. The positioning system is in communicational connection with the beacon units. The positioning system includes a radio receiving module, a first sound receiving module and a beacon recognizing module. Each beacon unit includes a radio transmitting module, a sound transmitting module and a second sound receiving module. Radio signals and sound signals are sent when the beacon units are triggered. The positioning system includes the radio signals and the sound signals of the beacon units and recognizes the received radio signals and the sound signals through the beacon recognizing module so as to locating the beacon units. The device provided by the invention is small in manufacture, low in product cost, small in size, flexible in mounting position, good in environment adaptability and insusceptible to environments. The device and the method provided by the invention can be applied to indoor and outdoor movable equipment widely, owing to the cooperative recognition of the sound signals and the radio signals.

Description

technical field [0001] The invention relates to a positioning technology, in particular to a sound radio coordinated positioning device and a method thereof. Background technique [0002] Most of the current positioning technologies rely on rotating laser rangefinders. The cost of choosing such devices is high, the volume is large, and the environmental requirements are high. For example, transparent objects such as glass cannot be detected. Contents of the invention [0003] In order to solve the problems of high cost, large size and high environmental requirements of the existing positioning technology, the present invention proposes a sound radio cooperative positioning device and its method, which have a simple structure and easy application, and can be realized through the cooperative identification of sound signals and radio signals Effective positioning in space. [0004] The technical solution adopted in the present invention is: a sound radio coordinated position...
