For example, the vehicle signal system is electrically connected to device 1 through cable 1, and is electrically connected to device 2 through cable 2. If the protective layer of cable 1 and cable 2 is damaged, resulting in the cores of the wires fitting together, when the on-board system sends a signal to device 1 through cable 1, the signal will be sent to device 2 simultaneously through cable 2, causing device 2 to receive an erroneous signal, which in turn causes the vehicle to malfunction and cause vehicle control disorder. At present, there is a lack of a device that can quickly determine that a cable has a cross-current fault, resulting in untimely handling of the cross-current fault, and there are major hidden dangers to the safe and stable operation of rail vehicles.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1As shown, the rail vehicle signal system line fault detection device provided by the utility model includes a plurality of warning units 1, one pole of each warning unit 1 is electrically connected to the vehicle signal system 2 of the rail vehicle, and the other pole of each warning unit 1 is electrically connected to the device 3 corresponding to the vehicle signal system 2 on the rail vehicle. The warning unit 1 has a power-on warning function, which means that when the vehicle signal system 2 sends a signal to the corresponding device 3, the warning unit 1 connected between the vehicle signal system and the corresponding device 3 performs a warning action. Assuming that the vehicle signal system 2 is connected to device A, device B, device C and device D through cables, under normal circumstances, when the vehicle signal system 2 sends a signal to device A, only device A can receive the signal and execute the corresponding instruction, and during the signal transmission process, the warning unit corresponding to device A will perform a warning action through the cable, and other warning units will not take action. Figure 2 As shown, when a cable cross-current occurs in the cables corresponding to device A and device B, both device A and device B can receive the signal and execute instructions. Since the detection device is usually close to the vehicle signal system, the cable cross-current failure usually occurs in the cable between the detection device and the device. Therefore, the warning unit corresponding to device B cannot be triggered at this time. The staff can determine that a cable cross-current failure has occurred in the lines corresponding to device A and device B by judging that the states of device A and device B and the corresponding warning units are inconsistent (that is, both device A and device B receive signals, but only the warning unit corresponding to device A is activated).
[0023] In an optional embodiment, the warning unit 1 is a light emitting diode, and the light emitting diode remains in a light emitting state when performing the warning action. The positive electrode of the light emitting diode is electrically connected to the output terminal of the vehicle signal system 2, and the negative electrode is connected to the device 3.
[0024] In an optional embodiment, the above device is installed on one side of the outgoing line end of the vehicle signal system 2 on the rail vehicle, and the outgoing line of the vehicle signal system 2 first passes through the light emitting diode of the detection device 3 and then is connected to each device 3 on the vehicle. By installing the detection device adjacent to the outgoing line end of the vehicle signal system 2, it is possible to avoid the detection device being unable to detect abnormalities due to a series current fault in the cable between the detection device and the vehicle signal system 2. Since the detection device 3 and the vehicle signal system 2 are located close to each other, the cable between the two is visible to the naked eye, and the staff can easily check this part of the cable without the help of the detection device 3.
[0025] In an optional embodiment, the device further comprises a processing unit, the processing unit having a plurality of input and output (IO) interfaces capable of acquiring the working state of the warning unit 1, and the input and output interfaces are electrically connected to the warning unit 1 in a one-to-one correspondence. The processing unit acquires the signal state of the corresponding warning unit 1 through the input and output interface, and thus acquires the action state information of the warning unit 1.
[0026] In an optional embodiment, the above-mentioned device also includes a communication unit electrically connected to the processing unit, and the communication unit has a communication port for communicating with the train control and management system 4 of the rail vehicle. Preferably, the communication port of the communication unit is connected to the train control and management system 4 (TCMS) of the rail vehicle through a hard line, and the action status information of the warning unit 1 is sent to the TCMS using Ethernet. After TCMS obtains the action status information of the warning unit 1, it compares the action status information of the warning unit 1 with the instruction execution status of the device 3. When the action status of the warning unit 1 is inconsistent with the instruction execution status of the device 3, it can be determined that a line series fault has occurred, and then an alarm is issued to remind the staff that the vehicle has malfunctioned and needs to be handled as soon as possible to avoid causing greater damage.
[0027] In an optional embodiment, the device further comprises a housing, and the processing unit, the communication unit and the warning unit 1 are installed inside the housing to protect the processing unit, the communication unit and the warning unit 1. An opening is provided on the surface of the housing for displaying the warning unit 1, and the staff can observe the operating status of the warning unit 1 through the opening.
[0028] In an optional embodiment, a plurality of marking areas are provided on the surface of the shell for identifying the lines corresponding to the warning unit 1, and the marking areas are located one by one on one side of the opening. For example, four marking areas A, B, C, and D can be set, corresponding to the warning units 1 corresponding to device 3A, device 3B, device 3C, and device 3D, respectively, to facilitate staff to identify faulty cables.
[0029] In an optional embodiment, the above-mentioned device also includes a buzzer electrically connected to the input and output interface of the processing unit. When TCMS determines that a cable series electrical fault has occurred, the cable fault determination result can be sent to the communication unit of the above-mentioned device. After receiving the cable fault determination result, the above-mentioned device can give a prompt by sounding a buzzer.
[0030] In an optional embodiment, the above device further includes the same number of fault indication units as the warning unit 1, and the fault indication units are electrically connected to the input and output ports of the processing unit one by one. Preferably, the fault indication unit can use an indicator light with a color different from that of the warning unit 1, and each indicator light corresponds to a cable. After the above device receives the cable fault determination result, the fault indication unit corresponding to the cable having the cable cross-current fault can be controlled to light up, so that the staff can determine which cables are damaged.
[0031] To sum up, the rail vehicle signal system line fault detection device provided by the utility model, when a cross-current fault occurs in the cable between the vehicle signal system and multiple devices, when the vehicle signal system sends a signal to one of the devices, the warning unit corresponding to the device in the detection device performs a warning action, and the other warning units do not take action. When the staff detects that the correspondence between the device that executes the signal and the warning unit is inconsistent, it can be determined that a cross-current fault has occurred in the cable, so that the staff can deal with the fault as soon as possible to avoid safety hazards.
[0032] The utility model also provides a rail vehicle, which includes any of the above-mentioned rail vehicle signal system line fault detection devices. It should be understood that the utility model does not limit the specific type of the rail vehicle. For example, the vehicle can be a motor vehicle, a diesel locomotive, a tram, etc. Since the rail vehicle is equipped with any of the above-mentioned rail vehicle signal system line fault detection devices, it also has corresponding technical effects.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.
[0034] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments.
