[0026] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements have the same or similar reference numbers and in which:

[0027] A train and its integrity detection system and method according to embodiments of the present application are described below with reference to the attached drawings.

[0028] Figure 1 is a structural block diagram of a train integrity detection system according to one embodiment of the present application.

[0029] As shown in Figure 1 , the detection system 1 comprises a first optical fiber detection module 10, a second optical fiber detection module 20 and a control module 30, wherein the first optical fiber detection module 10 and the second optical fiber detection module 20 are arranged between two carriages, as Figure 1The first and second carriages are described. The first fiber optic detection module 10 includes a first fiber optic transceiver 11 and a first fiber optic sensor head 12. The first fiber optic transceiver 11 is located near the first carriage, and the first fiber optic sensor head 12 is located near the second carriage. The first fiber optic transceiver 11 and the first fiber optic sensor head 12 are connected via a first fiber optic cable. The second fiber optic detection module 20 includes a second fiber optic transceiver 21 and a second fiber optic sensor head 22. The second fiber optic transceiver 21 is located near the second carriage, and the second fiber optic sensor head 22 is located near the first carriage. The second fiber optic transceiver 21 and the second fiber optic sensor head 22 are connected via a second fiber optic cable. The first fiber optic transceiver 11 and the second fiber optic sensor head 22 are connected via a third fiber optic cable, and the second fiber optic transceiver 21 and the first fiber optic sensor head 12 are connected via a fourth fiber optic cable. The control module 30 is connected to the first fiber optic transceiver 11 and the second fiber optic transceiver 21 respectively. The control module 30 is used to receive the switch signal output by the first fiber optic transceiver 11 and the switch signal output by the second fiber optic transceiver 21, and to determine whether the first carriage and the second carriage are intact based on the switch signal output by the first fiber optic transceiver 11 and the switch signal output by the second fiber optic transceiver 21.

[0030] Specifically, such as Figure 1 As shown, the detection system 1 in this embodiment can be installed between two carriages of the train, and the detection system 1 can be installed between every two carriages of the train to detect whether the connection between the two carriages is complete, thereby detecting the integrity of the train. In this embodiment, two fiber optic detection modules are set for redundant detection, namely the first fiber optic detection module 10 and the second fiber optic detection module 20 shown in Figure 1. The first fiber optic transceiver 11 of the first fiber optic detection module 10 is installed in the first carriage, and the first fiber optic sensor head 12 of the first fiber optic detection module 10 is installed in the second carriage. The first fiber optic transceiver 11 and the first fiber optic sensor head 12 are connected through a first fiber optic cable. Similarly, the second fiber optic sensor head 22 of the second fiber optic detection module 20 is installed in the first carriage, and the second fiber optic transceiver 21 of the second fiber optic detection module 20 is installed in the second carriage. The second fiber optic sensor head 22 and the second fiber optic transceiver 21 are connected through a second fiber optic cable. The first fiber optic transceiver 11 is also connected to the second fiber optic sensor head 22 via a third fiber optic cable, and the first fiber optic sensor head 12 is also connected to the second fiber optic transceiver 21 via a fourth fiber optic cable.

[0031] More specifically, the first fiber transceiver 11 in the first fiber detection module 10 sends an optical signal to the first fiber sensing head 12 through the first fiber, and the first fiber sensing head 12 can determine whether the first fiber is in a disconnected state or a connected state according to the optical signal after detecting the optical signal, and generate a corresponding switch signal according to the state of the first fiber, and then send the switch signal to the second fiber transceiver 21 through the fourth fiber. After receiving the switch signal corresponding to the state of the first fiber, the second fiber transceiver 21 can send the switch signal to the control module 30. The second fiber transceiver 21 in the second fiber detection module 20 sends an optical signal to the second fiber sensing head 22 through the second fiber, and the second fiber sensing head 22 can determine whether the second fiber is in a disconnected state or a connected state according to the optical signal after detecting the optical signal, and generate a corresponding switch signal according to the state of the second fiber, and then send the switch signal to the first fiber transceiver 11 through the third fiber. After receiving the switch signal corresponding to the state of the second fiber, the first fiber transceiver 11 can send the switch signal to the control module 30.

[0032] After receiving the switch signal sent by the first fiber transceiver 11 and the switch signal sent by the second fiber transceiver 21, the control module 30 can know the state of the first fiber and the second fiber. As can be understood, when the first fiber is completely connected to the first fiber transceiver 11 and the first fiber sensing head 12, the second fiber transceiver 21 can send a closed switch signal to the control module 30. Similarly, if the second fiber is also completely connected to the second fiber transceiver 21 and the second fiber sensing head 22, the first fiber transceiver 11 can send a closed switch signal to the control module 30. When the first fiber is disconnected, the first fiber sensing head 12 can send a disconnected switch signal to the second fiber transceiver 21, and the second fiber transceiver 21 sends the disconnected switch signal to the control module 30. Similarly, if the second fiber is disconnected, the first fiber transceiver 11 also sends a disconnected switch signal to the control module 30. It should be noted that if the first car and the second car are disconnected, the first fiber and the second fiber will be disconnected, and at this time the control module 30 receives a disconnected signal.

[0033] In some embodiments, referring to Figure 1 , when the switch signal output by the first fiber transceiver 11 and the switch signal output by the second fiber transceiver 21 are both disconnected signals, the control module 30 determines that the first car and the second car are not complete. Specifically, when the control module 30 receives a disconnected switch signal, it indicates that the first car and the second car are disconnected at this time, i.e., the train has a situation such as a train being thrown or a train being lost, and thus the detection of the completeness of the train can be completed.

[0034] In this embodiment, the first optical fiber and the second optical fiber have equal length, and the third optical fiber and the fourth optical fiber have equal length, wherein the length of the first optical fiber is greater than the length of the third optical fiber.

[0035] Specifically, as shown in Figure 1 , the first optical fiber and the second optical fiber have equal length, which can be selected according to the distance between two carriages in the train, and optionally, the length of the first optical fiber and the second optical fiber can be different for different types of trains. Of course, the length of the first optical fiber and the second optical fiber can also be longer than the distance between two carriages, so even if the first carriage and the second carriage are disconnected, the first optical fiber and / or the second optical fiber can still be used for buffering. When both the first optical fiber and the second optical fiber are disconnected, it is determined that the first carriage and the second carriage have been disconnected, and the train is not complete.

[0036] In one embodiment of the present application, as shown in Figure 2 , the first optical fiber detection module 10 further comprises a first analog detection object 13, which is arranged close to the second carriage and corresponds to the first optical fiber sensing head 12. The second optical fiber detection module 20 further comprises a second analog detection object 23, which is arranged close to the first carriage and corresponds to the second optical fiber sensing head 22. The first analog detection object 13 is used for sensing by the first optical fiber sensing head 12, so as to output an on-off signal through the second optical fiber transceiver 21. The second analog detection object 23 is used for sensing by the second optical fiber sensing head 22, so as to output an on-off signal through the first optical fiber transceiver 21.

[0037] Specifically, referring to Figure 2 , the first optical fiber sensing head 12 is correspondingly provided with the first analog detection object 13. For example, in the case that the first optical fiber is connected to the first optical fiber transceiver 11 and the first optical fiber sensing head 12, the first optical fiber transceiver 11 can send an optical signal to the first optical fiber sensing head 12. The first optical fiber sensing head 12 can detect the presence of the first analog detection object 13 after receiving the optical signal, and then output an on-off signal to the second optical fiber transceiver 21. The second optical fiber transceiver 21 further sends the on-off signal to the control module 30. The control module 30 can determine that the first optical fiber is currently in a complete connection state according to the on-off signal. The second analog detection object 23 has the same effect as the first analog detection object 13, which will not be described here.

[0038] In this embodiment, the first optical fiber transceiver 11 and the first optical fiber sensing head 12 constitute a first optical fiber sensor, and the second optical fiber transceiver 21 and the second optical fiber sensing head 22 constitute a second optical fiber sensor, and the first optical fiber sensor and the second optical fiber sensor have the same model.

[0039] For example, the first fiber sensor and the second fiber sensor are provided with a normally open relay, when the first fiber sensing head 12 receives the optical signal sent by the first fiber transceiver 11, the normally open relay can be controlled to be closed by detecting the first analog detection object 13, and then the closed switch signal is sent to the second fiber transceiver 21, and is sent to the control module 30 through the second fiber transceiver 21. If the first fiber is disconnected, the first fiber transceiver 11 cannot send the optical signal to the first fiber sensing head 12, so that the first fiber sensing head 12 cannot detect the presence of the first analog detection object 13, and the first fiber sensing head 12 generates an open switch signal according to the normally open relay, and then sends the open switch signal to the second fiber transceiver 21, and the second fiber transceiver 21 sends the open switch signal to the control module 30. It can be understood that the working mode of the second fiber detection module 20 is the same as that of the first fiber detection module 10, and the working process can be referred to the description of the working mode of the first fiber detection module 10, which will not be repeated here. More specifically, the first fiber sensor and the second fiber sensor in the embodiment are of the same type, so that the first sensor and the second sensor can interact more smoothly, and the detection speed of the train is further improved.

[0040] In an embodiment of the present application, as shown in Figure 3 The control module 30 includes a first vehicle controller 31 corresponding to the first car, a second vehicle controller 32 corresponding to the second car, and a ground area controller 33.

[0041] The first vehicle controller 31 is connected with the first fiber transceiver 11, and is used for receiving the first switch signal output by the first fiber transceiver 11; the second vehicle controller 32 is connected with the second fiber transceiver 21, and is used for receiving the second switch signal output by the second fiber transceiver 21; the ground area controller 33 is communicatively connected with the first vehicle controller 31 and the second vehicle controller 32, and is used for judging whether the first car and the second car are complete according to the first switch signal and the second switch signal.

[0042] Specifically, referring to Figure 3The control module 30 includes a first vehicle-mounted controller 31, a second vehicle-mounted controller 32, and a ground area controller 33. The first vehicle-mounted controller 31 is connected with the first fiber transceiver 11 to receive the first switch signal about the second fiber sent by the first fiber transceiver 11; the second vehicle-mounted controller 32 is connected with the second fiber transceiver 21 to receive the second switch signal about the first fiber sent by the second fiber transceiver 21. The first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 are further connected with the ground area controller 33 respectively, and the first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 further send the switch signal to the ground area controller 33 after receiving the switch signal, and the ground area controller 33 judges whether the first compartment and the second compartment are complete according to the first switch signal and the second switch signal. The specific judging mode can be referred to the above embodiment, and will not be described here. It should be noted that the ground area controller 33 can be connected with the first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 through wireless communication, and the first vehicle-mounted controller 31 can be connected with the second vehicle-mounted controller 32 through a vehicle-mounted network.

[0043] In an embodiment of the present application, as shown in Figure 4 The control module 30 includes a first vehicle-mounted controller 31 corresponding to the first compartment and a second vehicle-mounted controller 32 corresponding to the second compartment.

[0044] The first vehicle-mounted controller 31 is connected with the first fiber transceiver 11 to receive the first switch signal output by the first fiber transceiver 11; the second vehicle-mounted controller 32 is connected with the second fiber transceiver 21 to receive the second switch signal output by the second fiber transceiver 21; the first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 are connected in communication, so that one of the first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 judges whether the first compartment and the second compartment are complete according to the first switch signal and the second switch signal.

[0045] Specifically, referring to Figure 4 The control module 30 includes a first vehicle-mounted controller 31 and a second vehicle-mounted controller 32. The first vehicle-mounted controller 31 is connected with the first fiber transceiver 11 to receive the first switch signal about the second fiber sent by the first fiber transceiver 11; the second vehicle-mounted controller 32 is connected with the second fiber transceiver 21 to receive the second switch signal about the first fiber sent by the second fiber transceiver 21. The first vehicle-mounted controller 31 and the second vehicle-mounted controller 32 can be connected through wireless communication.

[0046] For example, when the first car of the train is the leading end, the second on-board controller 32 can send the received second switch signal to the first on-board controller 31, and the first on-board controller 31 can determine whether the first car and the second car are complete according to the first switch signal received by itself and the second switch signal sent by the second on-board controller 32. It can be understood that when the second car of the train is the leading end, the first on-board controller 31 can send the received first switch signal to the second on-board controller 32, and the second on-board controller 32 can determine whether the first car and the second car are complete according to the second switch signal received by itself and the first switch signal sent by the first on-board controller 31. Wherein, the specific determination method of whether the first car and the second car are complete according to the first switch signal and the second switch signal can refer to the above embodiment, which will not be repeated here.

[0047] In summary, the train integrity detection system of the embodiment of the present application can conveniently and quickly determine whether the train is complete, improve the real-time performance and detection accuracy of the train detection, and improve the anti-interference ability of the train integrity detection, while reducing the detection cost.

[0053] Specifically, as shown in the figure, Figure 1 The train in the embodiment is provided with two optical fiber detection modules for redundant detection, namely a first optical fiber detection module 10 and a second optical fiber detection module 20 shown in the figure, wherein the first optical fiber transceiver 11 of the first optical fiber detection module 10 is arranged in the first carriage, the first optical fiber sensing head 12 of the first optical fiber detection module 10 is arranged in the second carriage, and the first optical fiber transceiver 11 and the first optical fiber sensing head 12 are connected through a first optical fiber; similarly, the second optical fiber sensing head 22 of the second optical fiber detection module 20 is arranged in the first carriage, the second optical fiber transceiver 21 of the second optical fiber detection module 20 is arranged in the second carriage, and the second optical fiber sensing head 22 and the second optical fiber transceiver 21 are connected through a second optical fiber.

[0054] More specifically, the first fiber transceiver 11 in the first fiber detection module 10 sends an optical signal to the first fiber sensing head 12 through the first fiber, and the first fiber sensing head 12 can determine whether the first fiber is in a disconnected state or a connected state according to the optical signal after detecting the optical signal, and generate a corresponding switch signal according to the state of the first fiber, and then send the switch signal to the second fiber transceiver 21 through the fourth fiber. After receiving the switch signal corresponding to the state of the first fiber, the second fiber transceiver 21 can send the switch signal to the control module 30. The second fiber transceiver 21 in the second fiber detection module 20 sends an optical signal to the second fiber sensing head 22 through the second fiber, and the second fiber sensing head 22 can determine whether the second fiber is in a disconnected state or a connected state according to the optical signal after detecting the optical signal, and generate a corresponding switch signal according to the state of the second fiber, and then send the switch signal to the first fiber transceiver 11 through the third fiber. After receiving the switch signal corresponding to the state of the second fiber, the first fiber transceiver 11 can send the switch signal to the corresponding controller.

[0055] As shown in Figure 6 , the train integrity detection method comprises: S10, receiving the switch signal output by the first fiber transceiver and receiving the switch signal output by the second fiber transceiver. S20, determining whether the first car and the second car are complete according to the switch signal output by the first fiber transceiver and the switch signal output by the second fiber transceiver.

[0056] First of all, it needs to be pointed out that the train integrity detection method in this embodiment can be applied to the vehicle controller, such as Figure 1 the control module 30. Specifically, referring to Figure 1 and Figure 6, the control module 30 can know the state of the first optical fiber and the second optical fiber after receiving the switch signal sent by the first optical fiber transceiver 11 and the switch signal sent by the second optical fiber transceiver 21. As can be understood, when the first optical fiber is completely connected with the first optical fiber transceiver 11 and the first optical fiber sensing head 12, the second optical fiber transceiver 21 can send a closed switch signal to the control module 30. Similarly, if the second optical fiber is also completely connected with the second optical fiber transceiver 21 and the second optical fiber sensing head 22, the first optical fiber transceiver 11 can send a closed switch signal to the control module 30. When the first optical fiber is disconnected, the first optical fiber sensing head 12 can send a disconnected switch signal to the second optical fiber transceiver 21, and the second optical fiber transceiver 21 sends the disconnected switch signal to the control module 30. Similarly, if the second optical fiber is disconnected, the first optical fiber transceiver 11 also sends a disconnected switch signal to the control module 30. It should be noted that if the first car and the second car are disconnected, the first optical fiber and the second optical fiber will be disconnected, and at this time the control module 30 receives all disconnected signals. Therefore, in this embodiment, whether the first car and the second car are complete can be determined according to the switch signal output by the first optical fiber transceiver and the switch signal output by the second optical fiber transceiver.

[0057] In this embodiment, as shown in Figure 2 , the first optical fiber detection module 10 further comprises a first analog detection object 13, and the first analog detection object 13 is arranged close to the second car and corresponds to the first optical fiber sensing head 12. The second optical fiber detection module 20 further comprises a second analog detection object 23, and the second analog detection object 23 is arranged close to the first car and corresponds to the second optical fiber sensing head 22. The first analog detection object 13 is used for sensing by the first optical fiber sensing head 12, so as to output a switch signal through the second optical fiber transceiver 21. The second analog detection object 23 is used for sensing by the second optical fiber sensing head 22, so as to output a switch signal through the first optical fiber transceiver 21. As shown in Figure 6 , step S20 of determining whether the first car and the second car are complete according to the switch signal output by the first optical fiber transceiver and the switch signal output by the second optical fiber transceiver comprises: when the switch signal output by the first optical fiber transceiver and the switch signal output by the second optical fiber transceiver are both disconnected signals, it is determined that the first car and the second car are not complete.

[0058] Specifically, as shown in Figure 1 and Figure 6 , when the switch signals received by the control module 30 are all disconnected switch signals, it indicates that the first car and the second car are disconnected at this time, that is, the train has a situation such as train throwing or train loss, so that the detection of the completeness of the train can be completed.
