Problems solved by technology

However, it can only have high accuracy when the person to be positioned is in a static state, and it cannot guarantee real-time precise positioning of the person to be positioned when the person to be positioned is in a real-time moving state

Embodiment 1

[0052] Such as figure 1 As shown, this embodiment provides a method for accurately positioning indoor personnel, and the method includes the following steps:

[0053] S10: Receive node information sent by each reference node in the monitoring area and record the time point when the node information is received; wherein, the node information includes identity information or location information of the reference node;

[0054] Specifically, in this step, each reference node in the monitoring area is set to send node information to the device, and the device receives node information after receiving a wireless signal of a specific frequency (the wireless signal can be transmitted by the person to be located) , The successful reception will record the time point when the node information was received. The content of the node information sent by the reference node can be the identity information of the reference node or the position of the reference node in the monitoring area; it should...

Embodiment 2

[0061] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the method provided in this embodiment further includes after step S20:

[0062] S30: Detect whether the node information is received again within a preset time when the time point when the node information was received last time is the start time point, if not, check whether the human sensor in the monitoring area has sensed Personnel presence

[0063] This step is set to check whether the human sensor in the monitoring area senses the presence of a person without receiving the node information again. This can avoid the inability to obtain the location of the person after the node-free information is sent, and directly default that no person exists. Further improve the intelligence and accuracy of the gateway to calculate and analyze the position of the personnel, and ensure the intelligent processing when the personnel changes from moving to static. Because in the normal state, peo...

Embodiment 3

[0074] The difference between this embodiment and Embodiment 2 is that in the method provided in this embodiment, the step S21 includes:

[0075] S211: Identify the node information, and if the node information is the identity information of each reference node, extract the location information of each reference node according to a preset identity information and location information comparison table to obtain the information of each reference node Location; if the node information is the location information of each reference node, the location of each reference node is acquired according to the location information of the reference node.

[0076] Since the configuration of the reference node is different, there may be differences in the node information content, so the gateway is required to be able to identify the node information content, and process data differentiated according to the content, improve data processing efficiency, and increase the adaptability and practicability...

Abstract

The invention discloses an indoor personnel accurate locating method and system. The method comprises the steps that S10: the node information transmitted by each reference node in a monitoring area is received and the time point of receiving the node information is recorded, wherein the node information includes the identity information or the position information of the reference node; and S20:the position of the personnel side to be located is calculated according to the node information and the time point. The system comprises a portable signal transmitter, multiple reference nodes and agateway. Multiple reference nodes are arranged in the monitoring area to acquire the data capable of representing the movement situation of the personnel to be located in real time, the data are processed and then the personnel to be located is accurately located so that real-time locating under the movement state of the personnel to be located can be realized, the hardware configuration requirement of the reference nodes is low and the cost can be saved. Besides, the method and the system also have the advantages of low energy consumption and high locating accuracy.

Description

Technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a method and system for accurately positioning indoor personnel. Background technique [0002] With the development of smart home technology, the demand for indoor positioning is increasing. Traditional positioning technologies such as Global Positioning System (GPS) and Beidou system are mainly used for outdoor open locations. The positioning system established by synchronous satellites is used for positioning. When indoors, due to the signal blocking from the received building, the indoor satellite signal reception is poor and accurate positioning cannot be completed. [0003] In response to the above problems, there have also been some schemes in the prior art that use wireless signals for indoor positioning. Some of these schemes require personnel to wear electronic tags and actively transmit signals (such as radio) to achieve positioning through the electronic tags. The...
