Sound guidance location system

Abstract

The present invention provides a sound guidance location system. The system comprises a sound generation module, a sound receiving module, a single-chip microcomputer A, a single-chip microcomputer B, a first wireless communication module, a second wireless communication module, a motor driving module and a sound-light alarm module. The sound generation module, the first wireless communication module, the motor driving module and the sound-light alarm module are connected with the single-chip microcomputer A; the sound receiving module and the second wireless communication module are connected with the single-chip microcomputer B; and the first wireless communication module and the second wireless communication module can mutually transmit data information. The sound guidance location system employs sound to take as a location carrier, the sound receiving module is configure to obtain the coordinate information of the position where a dolly is located, and the driving direction of the dolly is controlled according to the coordinate information so as to reach the purpose that the dolly is moved according to a certain setting track. The sound guidance location system is convenient in manufacturing, simple in circuit, fast in response, accurate to control and low in cost.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of guidance and positioning, in particular to a sound guidance and positioning system. [0003] 【Background technique】 [0004] Positioning and guidance technology is a very old technology. The ancient positioning method first used astrology. Later, due to the discovery of geomagnetic phenomena and the discovery of magnetic materials, there was a compass. The positioning and guiding role of the compass opened the age of human navigation. [0005] With the rapid development of modern electronic technology, especially the development of radio technology, positioning and guidance have a new leap. GPS global positioning system is the representative of today's positioning system. It is widely used and has high positioning accuracy. It has penetrated into various fields of military and civilian use. The positioning and guidance of military aircraft and missiles all rely on GPS positioning system. Radio p...

Problems solved by technology

[0006] The modern method of positioning and guidance using radio technology has the advantages of high precision and strong interference ability, but it also has the disadvantages of large investment, large weight and volume of equipment, and high maintenance costs.

Therefore, it is often not suitable to use radio positioning and guidance systems in environments such as garages, mines, and large buildings.
