[0003] However, the existing positioning method still has the following defects. First, the receiving device needs to receive the detection signal and calculate the positioning position corresponding to itself, so the receiving device must be able to process related calculations, so that the receiving device The required efficiency and cost remain high. Moreover, in order to achieve accurate positioning in the existing positioning methods, multiple wireless signal transmitters need to be set up in the fixed area. For example, multiple Bluetooth base stations are set up in a room, and the The signal release ranges of the wireless signal transmitters not only need to overlap with each other, but each wireless signal transmitter must continue to broadcast the detection signal, so the accuracy of positioning may be affected by the interference of the signals between these wireless signal transmitters. influences

[0024] see figure 1, a first embodiment of the positioning system of the present invention includes a server 1, a first gateway 11 connected to the server 1 through a communication network 100, and a plurality of first gateways 11 connected to the first gateway 11 through the communication network 100 respectively. The receiver 12 , an object to be positioned 13 , and a mobile tag 14 installed on the object to be positioned 13 . The mobile tag 14 utilizes bluetooth communication technology to continuously broadcast an identification message including a unique tag identifier. The first receivers 12 are arranged in a space and are respectively located in different positions. Each first receiver 12 uses Continuously receiving identification information from the mobile tag 14 within a communicable range, in this embodiment, the mobile tag 14 can be a Bluetooth low energy beacon (Bluetooth low energy beacon), such as Apple (Apple) iBeacon, or Netvox's Wireless Wearable Presence Ta...

The invention relates to a positioning system utilizing multiple wireless signal receivers. Continuously broadcast the identification message through the mobile tag, so that the first receiver that receives the identification signal can calculate the wireless signal strength with the mobile tag according to the identification message, and use the first gateway to calculate the current time according to the current time Select the first target receiver from all the wireless signal information received in the interval, and use the position of the first target receiver as the first positioning position of the object to be positioned in the current time interval, so as to achieve The effect of locating the object to be positioned reduces the hardware cost of the device installed on the object to be positioned, and also greatly reduces the interference of signals.
Description
technical field [0001] The invention relates to a positioning system, in particular to a positioning system utilizing multiple wireless signal receivers. Background technique [0002] In today's society, wireless signal transmission technology is developing rapidly, and positioning methods using wireless signal communication technology are also developing. At present, whether it is in the logistics industry or the medical industry, positioning methods are applied to know the current location of products or patients. The existing positioning method mainly uses a receiving device installed on an object to be positioned, a plurality of wireless signal transmitters arranged in a fixed area and located in different positions, and a communication network connected to the wireless signal transmitters. The positioning method mainly includes the following steps: for each wireless signal transmitter, the wireless signal transmitter continuously broadcasts a detection signal, when the ...
