Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] At present, in the existing rail transit vehicle control system, during the standby power-on process, interaction failures often occur between the motion detection unit and the safety operation processing unit due to communication failures, which reduces the success rate of standby power-on and weakens availability. In addition, its power module usually controls the power on and off of the entire frame and lacks flexibility.

[0026] Based on this, a standby power-on device, a control method and a rail transit vehicle provided by an embodiment of the present invention can alleviate the above-mentioned technical problems.

[0027] To facilitate understanding of this embodiment, a standby power-on device disclosed in an embodiment of the present invention is first introduced in detail.

[0028] In a possible implementation manner, an embodiment of the present invention provides a standby power-on device, which is applied to rail transit vehicles, such as subways, light rails, monorail trains, trams, etc. Specifically, Figure 1 A structural schematic diagram of a standby power-on device is shown.

[0029] Among them, the motion detection unit communicates with the safety operation processing unit and the on-board central monitoring unit via wired communication; the discrete input and output acquisition unit also communicates with the motion detection unit;

[0030] Further, if Figure 1 As shown, the power module 10 includes a control board 101, and a switch circuit connected to the control board 101; the switch circuit includes a plurality of switch units 102, and the switch units 102 are respectively arranged on the connection paths between the power module 10 and the discrete input and output acquisition unit 20, the motion detection unit 30, the safe operation processing unit 40 and the vehicle-mounted central monitoring unit 50;

[0031] The control board 101 is connected to the external communication unit 60, and the external communication unit 60 is used to obtain power supply operation information and send a power supply signal to the power supply module 10 according to the power supply operation information;

[0032] The control board 101 is used to collect power supply signals, and control the power supply status of the discrete input and output acquisition unit 20, the motion detection unit 30, the safe operation processing unit 40 and the vehicle-mounted central monitoring unit 50 through the switch unit 102 according to the power supply signals.

[0033] The standby power-on device provided by the embodiment of the present invention includes: a power module, a discrete input and output acquisition unit, a motion detection unit, a safe operation processing unit, a vehicle-mounted central monitoring unit, and an external communication unit; wherein the motion detection unit communicates with the safe operation processing unit and the vehicle-mounted central monitoring unit by wire; the discrete input and output acquisition unit also communicates with the motion detection unit; the power module includes a control board, and a switch circuit connected to the control board; the switch circuit includes a plurality of switch units respectively arranged on the connection path between the power module and the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit; In addition, the external communication unit communicates with the control board, and when the power supply operation information is obtained, the power supply signal is sent to the power module according to the power supply operation information so that the control board controls the power supply status of the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the on-board central monitoring unit through the switch unit according to the power supply signal. Since the motion detection unit is wired with the safe operation processing unit and the on-board central monitoring unit, the failure rate of standby power-on due to wireless communication failure is reduced, and each unit is equipped with a switch unit to realize independent power on and off, making the configuration of the entire standby power-on device more flexible and improving the availability of the entire device during operation and maintenance.

[0034] In actual use, the above-mentioned power module 10, discrete input and output acquisition unit 20, motion detection unit 30, safe operation processing unit 40, vehicle-mounted central monitoring unit 50, and external communication unit 60 of the embodiment of the present invention are usually integrated in a preset cabinet, and the motion detection unit, the safe operation processing unit, the vehicle-mounted central monitoring unit, and the external communication unit constitute a safe multi-functional module of the standby power-on device; wherein the vehicle-mounted central monitoring unit and the external communication unit are arranged on the same sub-board; the sub-board includes processing units corresponding to the vehicle-mounted central monitoring unit and the external communication unit, respectively, and the functions of the vehicle-mounted central monitoring unit and the external communication unit are realized.

[0035] The safety multifunctional module is arranged on a function plug-in board, and the function plug-in board is arranged in a plug-in box of a preset cabinet. For example, the safety multifunctional module is arranged as a 6U standard plug-in board and installed in a 6U plug-in box. The discrete input and output acquisition unit can be arranged near the 6U plug-in box and arranged in the same preset cabinet as the safety multifunctional module.

[0036] For ease of understanding, Figure 1 On the basis of Figure 2 shows a schematic diagram of the structure of another standby power-on device, and, Figure 2 , a schematic diagram of a secure multifunctional module 200 is shown.

[0037] Furthermore, the above-mentioned switch unit of the above-mentioned embodiment of the present invention includes a MOS tube switch; the above-mentioned control board is also used to control the on-off state of the MOS (Metal Oxide Semiconductor Field Effect Transistor) tube switch according to the power supply signal to control the power supply state of the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit.

[0038] based on Figure 2 The standby power-on device shown in the figure combines multiple units in a preset cabinet. Through wired communication, the standby power-on failure rate caused by data packet loss caused by unstable wireless communication is reduced. Each unit is equipped with a MOS tube switch, which can realize the separate power on and off of each functional unit. It is not only flexible in configuration, but also improves the availability of the entire standby power-on device during operation and maintenance.

[0039] In actual use, the power module serves as the power supply for the entire standby power-on device and is mainly used for power conversion. Therefore, it is usually provided with a corresponding power conversion unit to convert the high-voltage power input from the power grid, for example, 110V to 24V or 110V to 5V, etc. The specific parameters and quantity of the power conversion unit can be set according to the actual usage of the corresponding board to realize the corresponding power conversion function, thereby supplying power to the entire standby power-on device.

[0040] Furthermore, the control board of the above-mentioned power module is usually an IO control board to collect the power supply signal output by the external communication unit, and the power supply signal is used to instruct the MOS tube switch of the switch unit to control the power on and off of the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit respectively.

[0041] In actual use, the above-mentioned motion detection unit, safe operation processing unit, vehicle-mounted central monitoring unit and external communication unit of the embodiment of the present invention respectively include their own processors, memories and input and output controls to facilitate the implementation of the functions of the corresponding units.

[0042] Further, if Figure 2 As shown, the discrete input-output acquisition unit includes an input-output control board; the discrete input-output acquisition unit is communicatively connected with the motion detection unit via the input-output control board 201 .

[0043] In addition, the motion detection unit communicates with the safety operation processing unit through a redundant wired network. The motion detection unit communicates with the vehicle-mounted central monitoring unit through a wired network.

[0044] In actual use, the power supply operation information acquired by the external communication unit includes power-off operation information so that the standby power-on device performs a power-off operation. Further, the power supply operation information also includes power-on operation information so that the standby power-on device performs a power-on operation.

[0045] Specifically, the step of the standby power-on device performing the power-off operation includes the following process:

[0046] (1) The motion detection unit sends a standby request to the safety operation processing unit;

[0047] (2) the safety operation processing unit is used to perform a standby check after receiving the standby request, and reply a check success signal to the motion detection unit after the check succeeds;

[0048] (3) The motion detection unit is also used to receive a verification success signal, confirm that the standby is successful, and send a standby success signal to the vehicle-mounted central monitoring unit;

[0049] (4) The on-board central monitoring unit is used to send power-off operation information to the external communication unit;

[0050] (5) The external communication unit is used to generate a power-off signal according to the power-off operation information, and send the power-off signal to the power module;

[0051] (6) The power module is used to control the switch circuit to disconnect according to the power-off signal, so as to perform a power-off operation on the discrete input and output acquisition unit, the motion detection unit, the safety operation processing unit and the on-board central monitoring unit.

[0052] In actual use, when the motion detection unit sends a standby request to the safe operation processing unit, it can be performed under the instruction of the discrete input and output acquisition unit or under the instruction of the vehicle-mounted central monitoring unit.

[0053] Usually, the discrete input and output acquisition unit can usually collect the standby signal acting on the vehicle. For example, the driver or the authorized vehicle staff can perform the standby operation through the corresponding operation control to generate the standby signal. At this time, the discrete input and output acquisition unit can collect the standby signal acting on the vehicle and output the collected standby signal to the motion detection unit; at this time, the motion detection unit is used to receive the standby signal sent by the discrete input and output acquisition unit and send a standby request to the safety operation processing unit;

[0054] Alternatively, the motion detection unit can detect the vehicle's driving information in real time during the operation of the vehicle, and the driving information includes speed information and / or position information; the on-board central monitoring unit is used to obtain the above-mentioned driving information, and judge the standby timing of the vehicle according to the driving information according to a preset processing logic, and generate a standby signal according to the standby timing, and send the standby signal to the motion detection unit; at this time, the motion detection unit is also used to receive the standby signal sent by the on-board central monitoring unit, and send a standby request to the safe operation processing unit.

[0055] Both of the above two methods can generate a standby request so as to perform the above power-off operation of the embodiment of the present invention.

[0056] Further, after the power-off operation, since the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit are all in a power-off state, only the external communication unit is still running. Therefore, when the standby power-on device performs the power-on operation, the power-on operation information is received through the external communication unit. Specifically, the power-on operation includes the following steps:

[0057] (1) The external communication unit is used to receive power-on operation information and send the power-on operation information to the power module;

[0058] (2) The power module is also used to control the closing of the switch circuit according to the power-on operation information, so as to perform the power-on operation on the discrete input and output acquisition unit, the motion detection unit, the safety operation processing unit and the vehicle-mounted central monitoring unit.

[0059] Specifically, after the power module receives the power-on operation information, the control board will control the various MOS tube switches included in the switch unit according to the power-on operation information to power on the discrete input and output acquisition unit, motion detection unit, safe operation processing unit and on-board central monitoring unit.

[0060] Furthermore, the motion detection unit is also configured with a memory; the memory is used to save the status data of the motion detection unit when the motion detection unit is powered off; the motion detection unit is also used to read the status data stored in the memory after power is turned on, and send a power-on request to the safe operation processing unit; the safe operation processing unit is also used to reply to the motion detection unit with a reply signal allowing power-on after receiving the power-on request, so that the motion detection unit performs a power-on operation after receiving the reply signal, to ensure that the motion detection unit can be fully powered on.

[0061] In summary, the standby power-on device provided in the embodiment of the present invention can set the power module, discrete input and output acquisition unit, motion detection unit, safe operation processing unit, vehicle-mounted central monitoring unit, and external communication unit in the same preset cabinet, and make the motion detection unit and the safe operation processing unit both located in the same plug-in box, and realize wired connection communication, thereby reducing the standby power-on failure rate caused by wireless communication failure, and each unit can be equipped with a MOS tube switch respectively to turn on and off the power separately, which not only has flexible configuration, but also improves the availability of the standby power-on device during operation and maintenance.

[0062] Further, based on the above embodiments, an embodiment of the present invention also provides a control method for a standby power-on device, which is applied to the above standby power-on device; specifically, the standby power-on device provided by the embodiment of the present invention includes: a power module, a discrete input and output acquisition unit, a motion detection unit, a safe operation processing unit, a vehicle-mounted central monitoring unit, and an external communication unit; the power module includes a control board, and a switching circuit connected to the control board; the switching circuit includes a plurality of switching units, and the switching units are respectively arranged on the connection path between the power module and the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit.

[0063] like Figure 3 A flow chart of a control method of a standby power-on device is shown, the method comprising the following steps:

[0064] Step S302, the external communication unit obtains power supply operation information, and sends a power supply signal to the power supply module according to the power supply operation information;

[0065] Step S304, the control board collects power supply signals, and controls the power supply status of the discrete input and output acquisition unit, the motion detection unit, the safe operation processing unit and the vehicle-mounted central monitoring unit through the switch unit according to the power supply signals.
