Example Embodiment

[0055] The parameters of the positioning repeater are configurable. If the parameter configuration is the same as that of the positioning tag, the return data of the positioning tag can be received. The positioning repeater has the ability to receive positioning tag signals. The positioning repeater has unlimited signal transmission capability and can send the data of the received positioning tag. When the sending port is set to the same channel parameters as the positioning gateway, it can be received by the positioning gateway. The positioning repeater has one or more independent radio frequency links. If it is a link, the transceiver shares the same link resource, and it needs to switch between the transceiver functions (not sending when receiving, and not receiving when sending. ), if there are more than two link resources, the transceiver can be set on different links, and the transceiver does not conflict (reception and transmission do not affect each other). The positio...

Example Embodiment

[0087] Example 4, such as Figure 8 As shown, room 1 and room 2 are areas that need to be located, and the positioning gateway and anchor point manager are deployed in room 3.

[0088] The location tag 1 is in a room, and it scans and receives the broadcast information of the location anchor points 1, 2, 3, 4, and obtains its identity ID and corresponding signal strength value. Then send its ID value and the received anchor information together. Since it is not in the coverage of the positioning gateway, the positioning gateway cannot receive the information of the positioning tag, so a positioning repeater needs to be placed between room 1 and room 2, its function is to receive the information sent by the positioning tag and forward it to the positioning Gateway. All the status information broadcast by the positioning anchor can be received by the anchor manager (the transmission frequency of the status information of the positioning anchor is low, so it can be set to send its...

Abstract

The invention discloses an indoor positioning system which comprises a plurality of positioning anchor points which periodically transmit self ID information through encrypted/non-encrypted broadcastframes, a positioning label which is arranged on a target to be positioned and scans and receives the ID information of the positioning anchor points and the signal strength RSSI values correspondingto the positioning anchor points, and emits the information and values in a wireless mode, a positioning gateway which receives and sends out the information sent by the positioning label in a wireless mode, a positioning server which receives the ID information of the positioning anchor points, the signal strength RSSI values and the ID of the positioning label, searches the positioning information of the corresponding positioning anchor points through the received ID information of the positioning anchor points, calculating the distance value between the positioning label and each positioning anchor point through the received signal strength RSSI value, and obtaining the indoor positioning information of the positioning label through a positioning algorithm. According to the indoor positioning system, high positioning precision can be obtained, and the requirements of rapid large-area coverage can be met.

Description

technical field [0001] The invention relates to the technical field of positioning. More specifically, the present invention relates to an indoor positioning system. Background technique [0002] With the development and popularization of Internet of Things technology, the connection between people and everything has become increasingly close. As an inherent attribute of a thing, location is in increasing demand. Outdoors, GPS technology can meet the location requirements in most outdoor scenarios, so GPS-based positioning technology has been widely used. As for the indoor environment, since the GPS signal cannot be covered, it cannot be directly applied indoors. At the same time, the indoor environment is more complex than the outdoor environment, although there are already a variety of indoor positioning solutions, such as UWB ultra-wideband, Bluetooth gateway passive positioning, inertial navigation, RFID area detection, etc. However, the high construction cost has al...
