Embodiment 1

[0052] like figure 1 As shown, this embodiment provides a method for accurate positioning of indoor personnel, 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, after receiving a wireless signal of a specific frequency (the wireless signal can be transmitted by the person to be located), send node information to the device, and the device receives the node information , the successful reception will record the time point when the node information is received, and the content of the node information sent by the reference node can be the identity information of the reference node, or the location set by the reference node in the monitoring ar...

Embodiment 2

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

[0062] S30: Detect whether the node information is received again within a preset time when the last time the node information was received is the start time point, and if not received, check whether the human body sensor in the monitoring area senses any the presence of personnel;

[0063] Setting this step, when the node information is not received again, check whether the human body sensor in the monitoring area senses the existence of a person, so as to avoid the situation that the person's location cannot be obtained after no node information is sent, and the situation that no person exists directly by default occurs. It further improves the intelligence and accuracy of the gateway's calculation and analysis of the location of the personnel, and ensures intelligent processing when the personnel cha...

Embodiment 3

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

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

[0076] Due to the different configurations of reference nodes, there may be differences in the content of node information, so the gateway needs to be able to identify the content of node information, process data differently according to the content, improve data processing efficiency, and increase the adaptab...

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 accurate positioning of 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 in outdoor open spaces. The positioning system established by synchronous satellite is used for positioning. When indoors, due to the signal blocking of the building, the indoor satellite signal reception is poor, and accurate positioning cannot be completed. [0003] In view of the above problems, there are also some solutions for indoor positioning using wireless signals in the prior art. In these solutions, some require personnel to wear electronic tags, and actively transmit signals (such as radio) to achieve positioning through electronic tags. The positioning metho...
