Example 5

The online dynamic identification method for the rail transit wheel identity and the loading position in the embodiment adopts the identification system in the embodiment 3 or 4, and the identification method comprises the following steps:

step one, train number and warehousing end position identification

When the train passes through the train number identification antenna 5, reading the electronic tags arranged below two ends of the train through the train number identification antenna 5, thereby obtaining the train number and the train warehousing end position;

step two, wheel identity information identification

When a train passes by, the electronic tags on the wheels of the train are sequentially read through the wheel identity recognition antennas 4 on the two sides of the track respectively, so that wheel identity information is obtained, the wheel identity information is sequentially numbered in the upper computer, and the mounting position of each wheel on the train is judged according to the train marshalling number, the naming mode and the end position orientation when the train is put in storage.

After the wheels are installed on the train, most of the wheels are shielded, only 1/4-1/3 are exposed outside, when the train moves forwards, the wheels move in two degrees of freedom, firstly, the wheels roll, secondly, the wheels move forwards along with the train, and the possibility that the wheels can be read by the antenna only when the installed electronic tags are exposed outside is achieved, so that the length of the antenna is larger than the circumference of the wheels, but the axle distance of the same bogie is smaller than the circumference of the wheels, the electronic tags of the two wheels enter the reading range of the antenna at the same time, the situation that the rear wheels are read firstly and the front wheels are read secondly can occur, and when the reading sequence of the wheels is reversed, the vehicle installation positions of the wheels are easy to judge wrongly. Therefore, after the car number, the warehousing end position and the wheel number are read, the following problems still need to be solved:

(1) the problem of how to match the wheel with the wheel position (namely the wheel is arranged at the vehicle mounting position) when reading missing does not occur;

(2) when the wheel is missed, the problem of matching the wheel with the wheel position is solved;

(3) when the rear wheel is read firstly and the front wheel is read secondly, the problem of how to correctly match the wheel at the mounting position of the vehicle occurs.

Since the first switch 601 and the second switch 602 are respectively installed at two ends of the wheel identification antenna 4, when the wheel triggers the first switch 601, it indicates that the wheel enters the reading area, when the wheel triggers the second switch 602, it indicates that the wheel leaves the reading area, and it is determined whether there is a wheel missing according to whether there is wheel information read within the time interval in which the first switch 601 and the second switch 602 are triggered, specifically, 6 groups of trains (including 6 cars, each car is installed with 2 bogies, each bogie has 2 wheel pairs, each wheel pair is formed by pressing 1 axle 8 and 2 wheels) are exemplified by the train with 48 wheels in total, 24 wheels on each side, and 8 wheels on each car).

The wheel positions on each side are numbered in sequence from 1 end position (cab at two ends of the train is respectively 1 end position and 2 end position), the left wheel of 1 shaft at 1 end position is numbered as 1, the left wheel is numbered as 3, 5, 7 and 9 … … 47 backwards in sequence, the right wheel of 1 shaft at 1 end position is numbered as 2, the left wheel is numbered as 4, 6, 8 and 10 … … 48 backwards in sequence, the wheel position numbers correspond to the wheel position names in the upper computer, for example, the known wheel position is 23, the upper computer is automatically matched to be the left wheel of 4 shafts of the C91 train (namely, the wheel numbers correspond to the installed positions, and the specific names of the wheels are different according to different wheel naming modes). When the train number identification antenna reads that the train warehousing end position is 1 end position, the antenna on the left side of the steel rail sequentially reads wheel positions 1, 3, 5, 7 and … … 47, and the antenna on the right side of the steel rail sequentially reads wheel positions 2, 4, 6, 8 and … … 48. When the train number identification antenna reads that the train warehousing end position is a 2-end position, the antenna on the left side of the steel rail sequentially reads wheel positions 48, 46, 44 and 42 … … 2, and the antenna on the right side of the steel rail sequentially reads wheel positions 47, 45, 43, 41 and … … 1. Therefore, when the wheels are not missed to read and are not read in sequence, the read wheels are easily matched with the wheel positions in sequence by combining the warehousing end positions, and finally matched with the positions of the vehicles.

When the wheel is missed, the upper computer not only needs to identify the position of the wheel which is missed, but also needs to supplement the number of the wheel which is missed, and the specific implementation mode is as follows: if no wheel information is read in during the triggering period of the first switch and the second switch, the missed reading can be generated, the in-train installation position of the missed reading wheel can be judged according to the train warehousing end position, and meanwhile, the upper computer can adopt two modes to fill in the missed reading wheel; and secondly, manually inputting the wheel number of the position.

Specifically, in this embodiment, the wheel identification antenna 4 is composed of three segments, a first antenna 401, a second antenna 402, and a third antenna 403, and a first switch 601 and a second switch 602 are respectively installed at the left end of the first antenna 401 and the right end of the third antenna 403. Since the wheel identification antennas 4 are arranged longer than the wheelbase of the bogie, there may be a case where two wheels enter the reading area at the same time. When this happens, the front wheel is necessarily located at the position of the third antenna 403, and is about to leave the reading area, and the rear wheel enters the reading area, so if the first antenna 401 reads the wheel number first and the third antenna 403 reads the wheel number later, it is considered that the rear wheel is read first and then the front wheel is read; if the third antenna 403 reads the wheel number first and the first antenna 401 reads the wheel number later, the front wheel is considered to be read first and the rear wheel is considered to be read later, and the judgment process is automatically completed in the upper computer.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
