Problems solved by technology

However, as the number of layers increases, both the ultrasonic positioning equipment and the amount of background data processing will increase, making the positioning method more complicated, even affecting the timeliness of positioning, and increasing the economic cost
In addition, the transmitter needs to transmit information such as ultrasonic emission time to the controller through other transmission technologies such as radio frequency, which also increases the complexity of the positioning method and system

Abstract

The invention discloses an indoor positioning method based on ultrasonic waves. The method comprises the steps that a mobile transmitting end transmits modulated ultrasonic waves; an ultrasonic wave receiving end group receives the modulated ultrasonic waves and transmits signal data to a controller; and the controller calculates the position of the mobile transmitting end according to the signaldata and preset rules. The invention furthermore discloses an indoor positioning system based on the ultrasonic waves. The system is characterized by comprising the mobile transmitting end, the ultrasonic wave receiving end group and the controller, wherein the ultrasonic wave receiving end group is connected with the controller, and the ultrasonic wave receiving end group is installed according to a specific position relation. By the adoption of the indoor positioning method and system based on the ultrasonic waves, the background data processing quantity can be reduced, so that positioning is more timely; and meanwhile, the quantity of ultrasonic positioning devices is reduced, and communication between the mobile transmitting end and the controller is not needed.

Description

technical field [0001] The present invention relates to an indoor positioning technology, in particular to an ultrasonic-based indoor positioning method and system Background technique [0002] In an open outdoor environment, the Global Positioning System (Global Positioning System, GPS for short) can provide very accurate positioning information. However, in industrial and agricultural production, military and national defense, it is sometimes necessary to perform positioning and monitoring in an indoor environment. For example, accurate indoor positioning information is required in the environment of robots, mobile vehicles, security protection, and mine operations to achieve efficient spatial control. Compared with the outdoor environment, the indoor environment is affected by building structure, internal layout and other artificial constraints, which have an impact on the accuracy and effectiveness of existing positioning systems, such as GPS positioning systems, especi...
