Problems solved by technology

Therefore, there is a problem: when the positioning beacon and the beacon node move, the above positioning algorithm will fail immediately, and when a large number of people locate the portable terminal or the mobile node quickly passes the positioning beacon and the beacon node, it is likely to cause card loss

Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see figure 1 , in an embodiment of the present invention, a wireless positioning sub-station and its working method, the system includes a wireless positioning sub-station 2, an identity card 3 and a base station 1, and the signal transmission mode between the wireless positioning sub-station, the identity card and the base station is wireless transmission. An identity in the identity card corresponds to the number of a wireless positioning sub-station. The embodiment...

Abstract

The invention discloses a wireless positioning substation and a working method thereof. A system comprises the wireless positioning substation, an identity card and a base station; a signal transmission mode adopted for the wireless positioning substation, the identity card and the base station with each other is a wireless transmission mode; an identity in the identity card corresponds to the serial number of one wireless positioning substation. The wireless positioning substation sends out low power signals and high power signals successively; if the low power signals are not received by the base station for continuous 6 times within the wireless signal coverage area of the base station, the wireless positioning substation starts sending out positioning information and the identity card receives the positioning information and transmits the positioning information to the base station; if the low power signals are received by the base station for continuous 6 times, the wireless positioning substation stops sending out the positioning information, and at the moment, the identity card automatically returns to the non-positioning state. The wireless positioning substation realizes mobile automobile transmission of desired information on demand, and therefore, the flexible requirements of different scenes on the deployment of the positioning accuracy on demand are met, and also a low-cost and high-accuracy positioning effect is realized.

Description

technical field [0001] The invention relates to the technical fields of personnel positioning, the Internet of Things, and wireless communication, and specifically relates to a wireless positioning sub-station and a working method thereof. Background technique [0002] The basic structure of the positioning system using RFID, ZigBee, Wi-Fi, UWB and other technologies is fixed deployment of card reader base stations, personnel carry positioning cards, and card reader base stations receive information from identity cards carried by personnel. Phase, ID card serial number and other information for identification and positioning. [0003] The above positioning process is based on the premise that there is no obstruction between the identity card and the card reader base station. However, in complex environmental conditions such as mines, construction tunnels, and storage yards, there are often various obstacles. Therefore, it is necessary to To achieve relatively accurate posit...
