specific Embodiment approach 1

[0021] The RFID positioning algorithm of a kind of fire training process of the present embodiment, described method is realized through the following steps:

[0022] Step 1, set the RFID reader at any location to capture 1-3 RFID cards, the numbers of the RFID cards are a, b, c, and the positioning algorithm calculation formula of the space coordinate code n of the RFID card is: :

[0023]

[0024] Step two, such as figure 1 As shown in the schematic diagram of M space, the number of small areas m can be divided within the range of a, b, and c, Then the range of a, b, c is regarded as a minimum measurement space M, and M can be regarded as a In a cuboid, the three points a, b, and c are located on three vertices that are not adjacent to each other; the overall space Q of the training room is regarded as composed of a finite number of M, and M 1 The initial setting of the three points is 1, 2, 3, then the space is respectively a=1; b=2; c=3; a+b 2 =5; a+c 2 =10; b...

specific Embodiment approach 2

[0028] Different from Embodiment 1, the RFID positioning system in the fire training process of this embodiment is composed of three parts: RFID reader, RFID card, and client. The fetcher captures the nearby RFID card, reads the number of the RFID card, uses an RFID positioning algorithm in the fire training process to calculate the positioning space coordinate code and sends it to the client, and the client performs corresponding display after receiving it.

Embodiment approach 1

[0029] Implementation plan 1: A fire simulation training room A:

[0030] The training room is a double-layer structure, each floor is 48 square meters, and the top floor is the first floor. The RFID card layout is as follows: figure 2 for the first layer, image 3 for the second layer.

Abstract

The invention discloses an RFID positioning system for a fire-fighting training process and an algorithm thereof, and an RFID positioning system and an algorithm thereof. In the training process of anexisting firefighter in a firefighter indoor drilling training room, due to the characteristics of short displacement and high speed, a common RFID positioning system is low in positioning precisionand high in cost. According to the RFID positioning system for a fire-fighting training process and the algorithm thereof, in the personnel moving process, the RFID reader captures nearby RFID cards and reads the serial numbers of the RFID cards, an RFID positioning algorithm in the fire-fighting training process is adopted to calculate positioning space coordinate codes and send the positioning space coordinate codes to the client side, and the client side correspondingly displays the codes after receiving the positioning space coordinate codes. According to the RFID positioning system in thefire-fighting training process and the algorithm thereof, the positioning precision is 0.5 m, the cost is about 80% of that of a common RFID positioning system, and other performances are equal to orslightly higher than those of the common RFID positioning system.

Description

technical field [0001] The invention relates to an RFID positioning system and an algorithm for the fire training process. Background technique [0002] The firefighter's indoor drill training room is a training facility that uses simulation technology to simulate the real fire environment to train firefighters. Since the training room is usually located indoors and is based on a three-dimensional iron cage, the structural environment is complex, and the signal of the structure is seriously affected. Therefore, it is difficult to achieve accurate positioning with external positioning systems such as the GPS global positioning system, and the error is too large to meet the requirements of indoor positioning. In this case, indoor positioning technologies based on RFID, WiFi, ZigBee, etc. are usually used. Compared with other technologies, RFID has low requirements for hardware equipment, fast response speed, strong stability and high positioning accuracy, so it has become the...
