[0028] In order to make the objects, technical solutions and advantages of the application clearer, the technical solutions in the application will be described clearly and completely in combination with the drawings in the application. Obviously, the described embodiments are some of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the application.

[0029] In the description of the embodiments of the application, the terms "first", "second", "third" are only used for description purpose, and cannot be understood as indicating or implying relative importance, and do not involve order.

[0030] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0031] The embodiments of the present application will be described below in conjunction with Figures 2 to 4 The axle counting system and the axle counting reset method provided by the present application are described.

[0032] Figure 2 is one of the structural diagrams of the axle counting system provided by the present application. The embodiments of the present application will be described below in conjunction with Figure 1 The axle counting system of the embodiments of the present application is described. As Figure 2 shown, the system comprises at least two sets of wheel sensors 101, a switching module 201 and an axle counting host 102; each set of wheel sensors 101 comprises two pairs of wheel sensors 101.

[0033] Specifically, unlike the conventional axle counting system which only comprises a single set of wheel sensors, the axle counting system provided by the embodiments of the present application redundantly configures wheel sensors, so that in the case that a single set of wheel sensors is interfered or fails to cause the axle counting reset to fail, the axle counting reset can be performed based on another set of wheel sensors, so that the track section can be normally reset to zero and the track section can be cleared, so that the corresponding turnout of the track section can be operated.

[0034] Optionally, the wheel sensor 101 is generally arranged outdoors.

[0035] Optionally, the switching module 201 is generally arranged indoors.

[0036] Optionally, the axle counting host 102 is generally arranged indoors.

[0037] At the first port and the second port of the target track section of the same track, one pair of wheel sensors and another pair of wheel sensors in one set of wheel sensors are arranged respectively.

[0038] The target track section is a section of track that needs to be reset. The target track section comprises two ports: a first port and a second port. It can be understood that the two tracks of the target track section correspond to each other, i.e. the first port of the first track of the target track section and the first port of the second track of the target track section are in the same coordinate, and the second port of the first track of the target track section and the second port of the second track of the target track section are in the same coordinate.

[0039] For any set of wheel sensors 101, the set of wheel sensors 101 can be arranged on the outer side of any one of the tracks in the pair of tracks. For any track section, the outer side of one of the tracks in the track section refers to the side away from the other track in the track section.

[0040] For any set of wheel sensors 101, one pair of wheel sensors 101 in the set of wheel sensors 101 can be arranged at the first port of the target track section, and the other pair of wheel sensors 101 can be arranged at the second port of the target track section, so that the axle host 102 can evaluate the wheel axle number returned by the set of wheel sensors 101 to generate the idle / occupied indication of the target track section. The axle host 102 can output the idle / occupied indication of the target track section through the relay contact state or the Ethernet interface.

[0041] Each set of wheel sensors 101 is connected to the switching module 201; the switching module 201 is used to connect one set of wheel sensors 101 in the at least two sets of wheel sensors 101 to the axle host 102.

[0042] Specifically, each set of wheel sensors 101 can be connected to the switching module 201 through a signal cable. The switching module 201 can be connected to the axle host 102 through a signal cable.

[0043] The switching module 201 can be used to connect one set of wheel sensors 101 in the axle system to the axle host 102, and the other sets of wheel sensors 101 are not connected to the axle host 102. That is, the axle host 102 can only be connected to one set of wheel sensors 101 in the axle system, and the specific set of wheel sensors 101 connected can be switched by the switching module 201.

[0044] It should be noted that when one set of wheel sensors 101 is connected to the axle host 102, the set of wheel sensors 101 is powered on and enters the working state; when one set of wheel sensors 101 is not connected to the axle host 102, the set of wheel sensors 101 is not powered on and does not enter the working state.

[0045] For the axle counting system provided by the embodiment of the present invention, when a set of wheel sensors 101 currently connected to the axle counting host 102 is interfered with or fails, resulting in a failure in axle counting reset, the switching module 201 can be used to switch the axle counting host 102 to be connected to another set of wheel sensors 101, and no longer be connected to the previously connected set of wheel sensors 101. Therefore, the axle counting host 102 can re-perform the axle counting reset operation based on the aforementioned other set of wheel sensors 101, reset the target track section normally, and clear the target track section, so that relevant operations can be performed on the switches corresponding to the target track section to avoid affecting the train's return.

[0046] In the embodiment of the present invention, multiple sets of wheel sensors serve as backup for each other. When axle counter reset fails due to interference or failure of a certain set of wheel sensors, the axle counter can be reset based on another set of wheel sensors. The track section can be reset to zero normally, the track section can be cleared, and relevant operations can be performed on the switches corresponding to the track section. The idle / occupied indication of the track section can be restored from an erroneous state to a correct state more quickly, and the problem of axle counter failure and occupation affecting switch operation or train reversal can be solved. The impact on train operation can be reduced, the safety of train operation can be improved, and the availability of wheel sensors can be enhanced.
