Abstract

The invention discloses a positioning signal repeater. The positioning signal repeater comprises a first central processing unit and a radio frequency transceiver, wherein the first central processing unit is in communication with the radio frequency transceiver through an SPI interface, the state signal output end of the radio frequency transceiver is connected with the state signal receiving end of the first central processing unit, the radio frequency transceiver comprises a second central processing unit, the second central processing unit is in communication with the first central processing unit through an SPI interface, the second central processing unit is connected with the first state signal receiving end and the second state signal receiving end of the first central processing unit through the first state signal output end and the second state signal output end respectively and connected with a power supply through a voltage stabilizing module, the second central processing unit is connected with a counter, a differential signal pin of the second central processing unit is connected with a differential signal receiving and sending module, the differential signal receiving and sending module is connected with an antenna, and the antenna is connected with an electronic tag and an AP machine through a wireless network.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning signal repeater used in a small area. Background technique [0002] In the field of real-time positioning technology, there are two types of satellite positioning systems, such as the GPS system and the domestic Beidou satellite positioning system, and precise positioning systems. Among them, satellite positioning is mainly used for vehicle-mounted positioning terminals in urban environments. The positioning accuracy is not high, and the error range is between several meters to tens of meters. Such accuracy cannot meet the requirements of precise positioning in small areas. However, with the development of Internet technology, the demand for positioning in indoor or park environments is also increasing, and the positioning accuracy requirements are gradually improving, and even need to reach a range of several meters or even centimeters, which results in the dev...
