Problems solved by technology

It does not require supervisors to be on duty continuously at the monitoring terminal, and can overcome false negatives due to human biological characteristics (such as visual fatigue, inability to concentrate for a long time, etc.). Identify a specific object among many objects, thereby reducing the work intensity of supervisors, enhancing rapid response capabilities, and improving management efficiency

Embodiment 1

[0136] An example of the above positioning method is Image 6 . See the icon on the lower right of the figure for the orientation position in the figure. A hexagon represents a house node, a circle represents an indoor node, a portrait and a triangle represent a person wearing a tag. The cell numbering rules in the picture are: when moving from the west side of the aisle to the east side, the first cell in the north is numbered I, the first cell in the south is numbered II, and moving eastward, the second cell in the south is numbered It is III, and the second cell in the north is numbered IV, that is, the cells are numbered by adding 1 to the order of the cells passing from west to east, "north, south, south, north". The actual number of the cell can be the same as the number of the above cell, or it can be numbered separately. The purpose of numbering the monitoring rooms is to lay the foundation for a simple and intuitive description of the monitoring network workflow be...

Embodiment 2

[0144] Another embodiment of the above positioning method is as Figure 7 . A hexagon represents a house number node, a pentagon represents a floor node, a portrait and a triangle represent a person wearing a tag. The installation position, numbering method and function of the house number nodes on the floor are the same as those in the cells and corridors, and will not be repeated here. There are two installation positions for floor nodes. One is installed directly above the first step of each staircase (0.8×H)m (H is the height of the floor, which does not affect the wireless transmission and reception of nodes, and can ensure that it is not easily damaged by moving objects), and each floor is installed One floor node; the other is installed at (0.8×H)m directly above the platform between floors, and a floor node is installed at each platform. The former floor node is directly named after F (Floor) plus the number of floors, such as F1, and the latter is named after the n...

Embodiment 3

[0150] Another embodiment of the above positioning method is as Figure 8 . A hexagon represents a house number node, a circle represents an indoor node, a square represents a cluster head node, a portrait and a triangle represent a person wearing a tag. Due to the large area of ​​the production area, the large number of people and the large flow of people, it is considered to divide the production area in advance. When dividing the area, try to divide each cluster area into a square with a side length of 10m. One cluster head node is installed in the center of the top wall of each cluster area, and one indoor node is installed in each of the four top wall corners. If the installation positions of indoor nodes in two cluster areas coincide, only one indoor node is installed. All cluster areas are numbered ①, ②, ③, etc. from left to right. The first cluster head node and the cluster head node of each cluster area are named after C and H followed by the cluster area number, s...

Abstract

The invention discloses a method for positioning multiple moving targets by a wireless sensor network syncretized with radio frequency identification (WSID), which comprises the following steps of: fixedly deploying WSID nodes at preset positions, electrifying and initiating the WSID nodes; configuring identification (ID) for each node by a base station respectively, establishing a position relation database of all nodes, and sending the ID of all the nodes and the position relation database to each node respectively; sending a data packet for establishing a network to each node by the base station, establishing the network, sending a data packet for establishing a cluster and determining a cluster head, and clustering the network; setting a WSID tag on a moving target, electrifying and initiating the tag, and computing the position coordinates of the moving target by self-correction positioning algorithm by the node and the tag on the moving target once the moving target provided with the tag enters a positioning area; and allowing the tag to send the position information of the moving target to the base station through the node by multi-hop routing, and sending the position information of the moving target to a monitoring terminal through networks such as Internet or GPRS or TD-SCDMA after the base station acquires the position information of the moving target.

Description

technical field [0001] The invention is applicable to multiple moving target monitoring in places such as prisons, detention centers, mental hospitals, drug rehabilitation centers, residential quarters, hospitals, nursing homes, kindergartens, etc., and particularly relates to a multi-moving target positioning method based on a wireless sensor network fused with radio frequency identification. Background technique [0002] The positioning of people as moving targets in places such as prisons, detention centers, mental hospitals and drug rehabilitation centers plays an extremely important role in the modern monitoring and management of public security prevention and control, investigation and detection, and emergency response in these places. It has always been an urgent problem that people need to solve. Key issues that have not been effectively resolved. Take the monitoring management of prison inmates and police officers as multiple moving targets as an example. Prison is...
