Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the protection scope of the present invention.

[0041] The following will describe Figures 1-5 the vehicle body separation and locking device, method and electronic device of the present invention.

[0042] As Figure 1 shown, the present invention provides a vehicle body separation and locking device, including:

[0043] Main air reservoir 111;

[0044] At least one locking module 120, as Figure 2 shown, the locking module 120 is fixed on the vehicle body 220, and continue to refer to Figure 1, the locking module 120 includes a locking solenoid valve 121, a pneumatic locking push device 122 that matches the locked structure fixed on the vehicle body 210, a separating solenoid valve 123, and a pneumatic separating push device 124 that matches the locked structure. The locking solenoid valve 121, the pneumatic locking push device 122, and the main air reservoir 111 are connected in series in sequence. The separating solenoid valve 123, the pneumatic separating push device 124, and the main air reservoir 111 are connected in series in sequence;

[0045] The locking control and monitoring module ( Figure 1 not shown in the figure) is electrically connected to the locking solenoid valve 121 and the separating solenoid valve 123, and is used to control the locking solenoid valve 121 to close based on a locking instruction, and control the separating solenoid valve 123 to close based on a separating instruction.

[0046] It can be understood that the vehicle body separation and locking device provided by the present invention can be applied to rail trains. Based on the characteristics of rail vehicles with separable vehicle bodies 210, 4 groups of locking modules 120 need to be installed on the chassis 220 corresponding to the vehicle body 210. These 4 groups of locking modules 120 are distributed in 4 different directions on the chassis 220 and are used to lock the vehicle body 210 when the vehicle body 210 is not separated. A locked structure is installed at the position on the vehicle body 210 corresponding to the locking module 120. The locking module 120 can perform a locking action or a separating action on the locked structure, thereby realizing the locking or separation of the vehicle body 210.

[0047] If the vehicle body 210 needs to be replaced, first automatically control the locking module 120 to perform a separating action. To achieve automatic control without adding additional control equipment, the locking module 120 is controlled by using the existing electric control and pneumatic control combination method of the vehicle.

[0048] The compressed air for controlling the locking module 120 to perform separating and locking actions comes from the main air reservoir 111. The main air reservoir 111 is an existing device of the vehicle. A branch is led out from the main air reservoir 111 to provide the compressed air required by the pneumatic locking push device 122 and the pneumatic separating push device 124.

[0049] In some embodiments, as Figure 3 shown, the locking control and monitoring module includes:

[0050] A circuit breaker 320;

[0051] A zero-speed relay 330;

[0052] Remote Input / Output Module (RIOM) 240, which includes a first point B1, a second point B2, a third point B3, and a fourth point B4, is used to connect the first point B1 to the third point B3 based on a locking instruction and connect the second point B2 to the fourth point B4 based on a separation instruction.

[0053] The power supply 310, the circuit breaker 320, the zero-speed relay 330, and the first point B1 are connected in series in sequence. The power supply 310, the circuit breaker 320, the zero-speed relay 330, and the second point B2 are connected in series in sequence. The third point B3 is connected to the locking solenoid valve 121, and the fourth point B4 is connected to the separation solenoid valve 123.

[0054] It can be understood that the locking control and monitoring module uses the existing Train Control and Management System (TCMS) and the 5G network module 220. The ground locking and separation instructions are sent to the vehicle control unit 260 through the 5G network module 220, and the vehicle control unit 260 controls the input / output module 240 to output locking and separation instructions.

[0055] The train control and management system includes: Vehicle Control Unit (VCU) 260, Ethernet Consist Network (ECN) 250, Remote Input / Output Module (RIOM) 240, 5G network module 220, main air reservoir 111, locking control and monitoring module, and 4 groups of locking modules 120.

[0056] Locking control process of the locking module 120: The power supply 310 outputs a DC voltage of 110V, which passes through the circuit breaker 320, and the current passes through the A1 and A2 contacts of the zero-speed relay 330. When the vehicle control unit 260 receives a locking instruction, it controls the first point B1 and the third point B3 of the input / output module 240 to conduct, and the voltage on the locking train line is 110V DC voltage. The locking solenoid valve 121 of the locking module 120 is connected in parallel to the locking train line. The locking solenoid valve 121 is energized to connect the air circuit, and the pressure of the main air reservoir 111 enters the pneumatic locking push device 122 to realize the automatic control of the locking module 120 to lock the car body 210. The zero-speed relay 330 ensures that only when the vehicle is in a zero-speed state can the input / output module 240 control the locking train line to be energized, that is, the locking instruction can only be executed when the train is in a stationary state.

[0057] Locking module 120 separation control process: The power supply 310 outputs a DC voltage of 110V, which passes through the circuit breaker 320. The current passes through the A1 and A2 contacts of the zero-speed relay 330. When the vehicle control unit 260 receives a separation instruction to control the second point B2 and the fourth point B4 of the input / output module 240 to conduct, the separation train line becomes a 110V DC voltage. The separation solenoid valve 123 of the locking module 120 is connected in parallel to the separation train line. When the separation solenoid valve 123 is energized, the air circuit is connected, and the pressure of the main air cylinder 111 enters the separation pushing device, realizing the automatic control of the locking module 120 to separate the locked car body 210. The zero-speed relay 330 ensures that only when the vehicle is in a zero-speed state can the input / output module 240 control the separation train line to be energized, that is, the separation instruction can only be executed when the train is stationary.

[0058] In some embodiments, the input / output module 240 further includes fifth points B51, B52, B53, B54;

[0059] The locking module further includes a first magnetic switch 340. The first end of the first magnetic switch 340 is electrically connected to the power supply 310 through the circuit breaker 320. The second end of the first magnetic switch 340 is connected to the fifth points B51, B52, B53, B54. The first magnetic switch 340 is used to close when the pneumatic locking pushing device 122 performs a locking action on the locked structure.

[0060] It can be understood that for locking state monitoring: A first magnetic switch 340 (i.e., the locking magnetic switch) is set in the locking module 120. When the locking is in place, the first magnetic switch 340 closes, and the 110V DC voltage passes through the circuit breaker 320 to the locking separation monitoring power supply line. The first magnetic switch 340 of the locking module 120 is connected in parallel to the locking separation monitoring power supply line. When the locking is in place and the first magnetic switch 340 closes, the input / output module 240 monitors a high level, and it can be considered that the locking module 120 is in the locking state.

[0061] Furthermore, the locking module 120 also contains a metal conductor. By sensing the closing action of the locking solenoid valve 121 or the separation solenoid valve 123 through the metal conductor, after sensing the closing action of the locking solenoid valve 121, the metal conductor will move to the first magnetic switch 340, and the first magnetic switch 340 closes. After sensing the closing action of the separation solenoid valve 123, the metal conductor will move to the second magnetic switch 350, and the second magnetic switch 350 closes.

[0062] In some embodiments, the input / output module 240 further includes sixth points B61, B62, B63, B64;

[0063] The locking module further includes a second magnetic switch 350. The first end of the second magnetic switch 350 is electrically connected to the power supply 310 through the circuit breaker 320. The second end of the second magnetic switch 350 is connected to the sixth positions B61, B62, B63, and B64. The second magnetic switch 350 is configured to close when the pneumatic separation pushing device 124 performs a separation action on the structure to be locked.

[0064] It can be understood that for separation state monitoring: a second magnetic switch 350 (i.e., separation magnetic switch) is provided in the locking module 120. When the separation is in place, the second magnetic switch 350 closes, and the 110V DC voltage passes through the circuit breaker 320 to the locking and separation monitoring power supply line. The second magnetic switch 350 of the locking module 120 is connected in parallel to the locking and separation monitoring power supply line. When the separation is in place, the second magnetic switch 350 closes, and the input / output module 240 monitors a high level, determining that the locking module 120 is in the separation state.

[0065] In some embodiments, the vehicle body separation and locking device further includes:

[0066] An indicator light 360, the indicator light 360, the second magnetic switch 350, the circuit breaker 320, and the power supply 310 are connected in series; the indicator light 360 is configured to be lit when both the second magnetic switch and the circuit breaker are closed.

[0067] It can be understood that when the second magnetic switch 350 closes, the indicator light 360 is lit, which can notify the user that the second magnetic switch 350 has closed.

[0068] In some embodiments, the number of the second magnetic switches 350 is at least two;

[0069] The locking control and monitoring module further includes:

[0070] Diodes 370, one diode 370 corresponds to each second magnetic switch 350, and the diode 370 is connected in series between the second magnetic switch and the indicator light 360, and the negative electrode of the diode 370 is connected to the indicator light; the diode 370 is configured to block the reverse current of the diode.

[0071] It can be understood that when the second magnetic switches 350 of the locking module 120 close, they are respectively connected to their respective diodes 370. After all the diodes 370 are connected in parallel, they are connected to the separation indicator light 360 of the locking module 120 at both ends. The diode 370 can prevent the influence of one second magnetic switch 350 closing on the input / output modules 240 of the other three.

[0072] In some embodiments, the vehicle body separation and locking device further includes: a cut-off ball valve 112 and a pressure reducing valve 113. The main air reservoir 111, the cut-off ball valve 112, the pressure reducing valve 113, and the locking module 120 are connected in series in sequence.

[0073] It can be understood that adding a cut-off ball valve 112 upstream of the branch line led out from the main air reservoir 111 can prevent air leakage in the pipeline or the locking module 120 from affecting the pressure of the main air reservoir 111, and further affecting the air for train braking and the pressure of the air springs, etc.

[0074] A pressure reducing valve 113 is arranged downstream of the cut-off ball valve 112 to make the control pressure adapt to the usage scenario of the locking module 120. The compressed air discharged from the pressure reducing valve 113 leads to the locking solenoid valve 121 and the separation solenoid valve 123 of the locking module 120. By controlling the energization and de-energization of the solenoid valves, the compressed air is controlled to enter the cylinders of the locking or separation pushing devices, realizing the locking and separation of the vehicle body 210 and the chassis 220.

[0075] In some embodiments, the number of the locking modules is 4, and the 4 locking modules are respectively fixed at different positions on the vehicle chassis.

[0076] It can be understood that the 4 locking modules are respectively fixed at 4 different positions on the front left, front right, rear left, and rear right of the vehicle chassis.

[0077] In summary, the vehicle body separation and locking device provided by the present invention includes: a main air reservoir 111; a locking module 120, the locking module 120 is fixed on the vehicle body 220, the locking module 120 includes a locking solenoid valve 121, a pneumatic locking pushing device 122 matching the locked structure fixed on the vehicle body 210, a separation solenoid valve 123, and a pneumatic separation pushing device 124 matching the locked structure. The locking solenoid valve 121, the pneumatic locking pushing device 122, and the main air reservoir 111 are connected in series in sequence, and the separation solenoid valve 123, the pneumatic separation pushing device 124, and the main air reservoir 111 are connected in series in sequence; a locking control and monitoring module, electrically connected to the locking solenoid valve 121 and the separation solenoid valve 123, for controlling the locking solenoid valve 121 to close based on a locking instruction, and controlling the separation solenoid valve 123 to close based on a separation instruction.

[0078] In the vehicle body separation and locking device provided by the present invention, by inputting an instruction to the locking control and monitoring module, the locking control and monitoring module is controlled to close the locking solenoid valve 121, and then the main air reservoir 111 is controlled to output compressed air to the pneumatic locking push device 122 to achieve the locking operation of the vehicle body and the chassis. Or, the locking control and monitoring module is controlled to close the separation solenoid valve 123, and then the main air reservoir 111 is controlled to output compressed air to the pneumatic separation push device 124 to achieve the separation operation of the vehicle body and the chassis. Therefore, in the present invention, by inputting a control instruction to the locking control and monitoring module, the locking and classification operations of the vehicle body and the chassis can be completed, realizing the intelligent control of the locking and separation of the vehicle body, and thus realizing the automatic replacement of the vehicle body.
