Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply of rail vehicles, in particular to a rail vehicle pantograph control device, method and rail vehicle. BACKGROUND

[0002] The pantograph is a device for rail vehicles to obtain high-voltage power, and if it fails, the vehicle will not be able to obtain power and will not be able to run.

[0003] Currently, a rail vehicle usually has two pantographs, which are installed on two carriages respectively. When operating the pantograph lifting, the staff can control the lifting of the pantograph of the current carriage and the pantograph of the opposite end carriage at the same time. The current commonly used pantograph control method is to set a pantograph selection switch, a pantograph lifting control button, a pantograph lowering control button and a relay and other components for logical control to realize the simultaneous control of the two pantographs, but the control circuit logic is complex, and many relays are carried, which results in a high failure rate and poor reliability. Moreover, during the process of the rail vehicle running through the pantograph power supply, only one pantograph is usually allowed to rise (if two pantographs are raised at the same time, the situation that two pantographs are damaged at the same time may occur in case of failure, the maintenance cost is increased, and when one pantograph runs alone, the carbon slide plate is only worn out, which is less worn out than the carbon slide plate worn out when two pantographs run at the same time, and can be used for a longer time), under the premise that the two pantographs cannot be raised at the same time, manual judgment is usually required, so that the safety of the rail vehicle power supply cannot be guaranteed.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] The following is combined Figures 1-3 The first embodiment of the present invention describes a pantograph control device for rail vehicles.

[0030] This embodiment of a rail vehicle pantograph control device includes: a local pantograph lifting unit 1, a remote pantograph lifting unit 2, and a network control unit 3. The network control unit 3 is used to receive local pantograph lifting commands sent by the local pantograph lifting unit 1 or remote pantograph lifting commands sent by the remote pantograph lifting unit 2, and control the lifting and lowering of the local pantograph and the remote pantograph according to their respective states, ensuring that at most one pantograph is in a raised state.

[0031] like Figure 1As shown in the figure, the rail vehicle pantograph control device comprises a local pantograph lifting unit 1, an opposite pantograph lifting unit 2, a network control unit 3, a key interlocking box 4, an electromagnetic valve 5 and a cab activation switch 6.

[0032] The local pantograph lifting unit 1 and the opposite pantograph lifting unit 2 are respectively connected with the input end of the network control unit 3. The local pantograph lifting unit 1 and the opposite pantograph lifting unit 2 are both self-resetting pantograph lifting buttons, and one press can send a pantograph lifting instruction (pulse signal) to the network control unit 3 and reset.

[0033] The network control unit 3 is used for receiving the local pantograph lifting instruction sent by the local pantograph lifting unit 1 or the opposite pantograph lifting instruction sent by the opposite pantograph lifting unit 2, and controlling the lifting of the local pantograph and the opposite pantograph according to the state of the local pantograph and the opposite pantograph, so as to ensure that at most one pantograph is in the lifting state. The output end of the network control unit 3 is connected to the local pantograph electromagnetic valve 5 and the opposite pantograph electromagnetic valve 5. Specifically, the network control unit 3 sends a local pantograph lifting instruction and a local pantograph lowering instruction to the local pantograph through the “local pantograph lifting” signal line and the “local pantograph lowering” signal line respectively, and sends an opposite pantograph lifting instruction and an opposite pantograph lowering instruction to the opposite pantograph through the “opposite pantograph lifting” signal line and the “opposite pantograph lowering” signal line respectively.

[0034] Among them, the local pantograph lifting signal line switch and the opposite pantograph lifting signal line switch connected with the output end of the network control unit 3 are interlocked. In this embodiment, the “local pantograph lifting” signal line and the “opposite pantograph lifting” signal line realize the interlocking function through the key interlocking box 4, so that the “local pantograph lifting” signal line and the “opposite pantograph lifting” signal line can be turned on and turned off at the same time. When the vehicle is being repaired, the staff rotates the key, the key interlocking signal is turned off, and even if someone mistakenly presses the pantograph lifting button, the pantograph cannot be lifted, which ensures the safety of the repair.

[0035] The electromagnetic valve 5 is used for controlling the lifting action of the corresponding pantograph, as shown in the figure. Figure 2 and Figure 3 In this embodiment, the electromagnetic valve 5 is a two-position three-way double-control electromagnetic valve 5, and the electromagnetic valve 5 is provided with a manual pantograph lifting button 51 and a manual pantograph lowering button 52. When receiving the lifting instruction, the 1A end of the electromagnetic valve 5 is excited, the input port K1 and the output port K2 are connected, and the exhaust port K3 is closed, so that the pantograph is lifted. When receiving the lowering instruction, the 1B end of the electromagnetic valve 5 is excited, the input port K1 is closed, the output port K2 and the exhaust port K3 are communicated, and the pantograph is lowered. In the case of network control unit 3 failure, the lifting instruction and the lowering instruction cannot be sent, and the pantograph can be controlled by the manual pantograph lifting button 51 and the manual pantograph lowering button 52 on the electromagnetic valve 5, so as to ensure the normal operation of the train.

[0036] Two carriages of the rail vehicle in the embodiment are respectively provided with a rail vehicle pantograph control device. Thus, the staff in the local carriage can simultaneously control the pantographs of the local and opposite carriages, and the staff in the opposite carriage can simultaneously control the pantographs of the opposite and local carriages.

[0037] The network control unit 3 comprises an instruction receiving module, a state judging module and an instruction sending module. The instruction receiving module is configured to receive a local pantograph lifting instruction or an opposite pantograph lifting instruction. The state judging module is configured to judge the states of the local pantograph and the opposite pantograph according to the pantograph lifting instruction, so as to determine the lifting action of the corresponding pantograph. The instruction sending module is configured to send a pantograph lifting instruction or a pantograph lowering instruction (pulse signal) to the corresponding pantograph according to the lifting action.

[0038] Specifically, when the instruction receiving module receives the local pantograph lifting instruction, the state judging module judges the state of the local pantograph. If the local pantograph is in the pantograph lifting state, it is determined that the local pantograph is in the pantograph lowering action, and the instruction sending module sends the pantograph lowering instruction to the local pantograph. If the local pantograph is in the pantograph lowering state, the state judging module judges the state of the opposite pantograph. If the opposite pantograph is in the pantograph lifting state, it is determined that the local pantograph is in the pantograph lowering action, and the instruction sending module does not send the instruction. If the opposite pantograph is in the pantograph lowering state, it is determined that the local pantograph is in the pantograph lifting action, and the instruction sending module sends the pantograph lifting instruction to the local pantograph.

[0039] When the instruction receiving module receives the opposite pantograph lifting instruction, the state judging module judges the state of the opposite pantograph. If the opposite pantograph is in the pantograph lifting state, it is determined that the opposite pantograph is in the pantograph lowering action, and the instruction sending module sends the pantograph lowering instruction to the opposite pantograph. If the opposite pantograph is in the pantograph lowering state, the state judging module judges the state of the local pantograph. If the local pantograph is in the pantograph lifting state, it is determined that the opposite pantograph is in the pantograph lowering action, and the instruction sending module does not send the instruction. If the local pantograph is in the pantograph lowering state, it is determined that the opposite pantograph is in the pantograph lifting action, and the instruction sending module sends the pantograph lifting instruction to the opposite pantograph.

[0040] In the process of judging the states of the local and opposite pantographs, the state judging module judges whether the corresponding pantograph is in the pantograph lowering state or the pantograph lifting state according to the collected signals. For example, when the state judging module receives the pantograph lowering in-position signal of the pantograph, it is judged that the pantograph is in the pantograph lowering state. When the state judging module does not receive the pantograph lowering in-position signal of the pantograph, receives the pantograph lifting in-position signal of the pantograph or receives the network voltage signal of the pantograph, it is judged that the pantograph is in the pantograph lifting state.

[0041] The network control unit 3 controls the lifting of the corresponding pantograph through the above program logic, guarantees the reliability of the pantograph operation, and ensures that the two pantographs cannot be lifted at the same time, thereby guaranteeing the power supply safety.

[0042] In the circuit structure of the embodiment, the local pantograph lifting unit 1 and the opposite pantograph lifting unit 2 are connected with the network control unit 3, so that the network control unit 3 receives the local pantograph lifting instruction sent by the local pantograph lifting unit 1 or the opposite pantograph lifting instruction sent by the opposite pantograph lifting unit 2. The control unit judges the states of the two pantographs according to the received instructions, analyzes according to the current pantograph state, sends pulse signals to the electromagnetic valves 5 of the local pantograph or the opposite pantograph through the four signal lines of the output end, and the electromagnetic valves 5 are excited after receiving the corresponding pulse signals, so as to control the lifting of the local pantograph and the opposite pantograph.

[0043] The control device for the pantograph of the rail vehicle provided in the embodiment is characterized in that a local pantograph lifting unit 1 for controlling the local pantograph of the local carriage, an opposite pantograph lifting unit 2 for controlling the opposite pantograph of the opposite carriage, and a network control unit 3 are arranged in the local carriage. The local pantograph lifting unit 1 and the opposite pantograph lifting unit 2 are connected with the network control unit 3, so that the network control unit 3 receives the local pantograph lifting instruction sent by the local pantograph lifting unit 1 or the opposite pantograph lifting instruction sent by the opposite pantograph lifting unit 2. The control unit judges the states of the two pantographs according to the received instructions, analyzes according to the current pantograph state, controls the lifting of the local pantograph and the opposite pantograph, and ensures that at most one pantograph is in the lifting state. The network control unit 3 analyzes the received lifting instruction in combination with the current pantograph state to control the lifting of the corresponding pantograph, which greatly optimizes the circuit structure compared with the existing control circuit logic, guarantees the reliability of the pantograph operation, and ensures that the two pantographs cannot be lifted at the same time through the pantograph state analysis, thereby guaranteeing the power supply safety.

[0044] In the embodiment, the network control unit 3 comprises an instruction receiving module, a state judging module, and an instruction sending module.

[0045] The instruction receiving module is configured to receive the local pantograph lifting instruction or the opposite pantograph lifting instruction.

[0046] The state judging module is configured to judge the states of the local pantograph and the opposite pantograph according to the pantograph lifting instruction, so as to determine the lifting action of the corresponding pantograph.

[0047] The instruction sending module is configured to send the lifting instruction to the corresponding pantograph of the pantograph lifting unit according to the lifting action.

[0048] The network control unit 3 processes the steps of the instruction, first receives the pantograph lifting instruction by the instruction receiving module. Then the state judgment module judges the pantograph state of the local and the opposite end according to the specific pantograph lifting instruction, to determine the lifting action of the corresponding pantograph, that is, the pantograph lifting instruction finally needs to be executed. Finally, the instruction sending module sends the pantograph lifting instruction or the pantograph lowering instruction to the corresponding pantograph. The network control unit 3 realizes the control of the double-end pantograph through the above modules and execution logic, which optimizes the circuit structure of the existing device and guarantees the reliability of the pantograph operation.

[0049] In the embodiment, when the instruction receiving module receives the local pantograph lifting instruction, the state judgment module judges the local pantograph state. If the local pantograph is in the lifting state, it is determined that the local pantograph is in the lowering action, and the instruction sending module sends the lowering instruction to the local pantograph. If the local pantograph is in the lowering state, the state judgment module judges the opposite pantograph state. If the opposite pantograph is in the lifting state, it is determined that the local pantograph is in the lowering action, and the instruction sending module does not send the instruction. If the opposite pantograph is in the lowering state, it is determined that the local pantograph is in the lifting action, and the instruction sending module sends the lifting instruction to the local pantograph.

[0050] When the instruction receiving module receives the opposite pantograph lifting instruction, the state judgment module judges the opposite pantograph state. If the opposite pantograph is in the lifting state, it is determined that the opposite pantograph is in the lowering action, and the instruction sending module sends the lowering instruction to the opposite pantograph. If the opposite pantograph is in the lowering state, the state judgment module judges the local pantograph state. If the local pantograph is in the lifting state, it is determined that the opposite pantograph is in the lowering action, and the instruction sending module does not send the instruction. If the local pantograph is in the lowering state, it is determined that the opposite pantograph is in the lifting action, and the instruction sending module sends the lifting instruction to the opposite pantograph.

[0051] The state judgment module first judges the lifting state of the pantograph corresponding to the instruction according to the received local pantograph lifting instruction or opposite pantograph lifting instruction. If the pantograph corresponding to the instruction is in the lifting state, it can be directly lowered. If the pantograph corresponding to the instruction is in the lowering state, it needs to be combined with the lifting state of the other end (opposite end) to judge. If the other end pantograph is in the lifting state, it means that there is at most one pantograph lifted on the rail vehicle, which cannot be lifted under the premise that the pantograph corresponding to the instruction is in the lowering state. At this time, it is determined that the pantograph corresponding to the instruction continues to be in the lowering action, that is, no instruction is sent. If the other end pantograph is in the lowering state, it means that there is no pantograph lifted on the rail vehicle, so the pantograph corresponding to the instruction can be lifted. Through the above judgment logic, it is ensured that the two pantographs cannot be lifted at the same time, which guarantees the safety of power supply.

[0052] In the embodiment, the state judging module judges the pantograph as a lowering pantograph state when receiving the lowering pantograph in position signal of the pantograph; and judges the pantograph as a raising pantograph state when not receiving the lowering pantograph in position signal of the pantograph, receiving the raising pantograph in position signal of the pantograph, and receiving the network voltage signal of the pantograph.

[0053] The state judging module needs to receive the lowering pantograph in position signal of the pantograph to judge the pantograph as a lowering pantograph state. When not receiving the lowering pantograph in position signal of the pantograph, or receiving the raising pantograph in position signal of the pantograph, or receiving the network voltage signal of the pantograph, one or more of the above three conditions are met, and the pantograph is judged as a raising pantograph state. This ensures accurate judgment of the pantograph raising and lowering state to avoid misjudgment of the pantograph raising and lowering state causing serious consequences.

[0054] In the embodiment, the network control unit 3 is connected to the local pantograph raising signal line switch and the opposite end pantograph raising signal line switch.

[0055] The local pantograph raising signal line switch and the opposite end pantograph raising signal line switch are interlocked, so that the local pantograph raising signal line and the opposite end pantograph raising signal line can be turned on and turned off at the same time. When the vehicle is being repaired, the two end pantograph raising signal lines are turned off at the same time, which can ensure that the pantograph cannot be raised even if someone mistakenly presses the pantograph raising and lowering button, thereby ensuring safety during repair.

[0056] In the embodiment, the network control unit 3 controls the raising and lowering of the local pantograph and the opposite end pantograph by sending a pantograph raising and lowering instruction to the electromagnetic valve 5.

[0057] The electromagnetic valve 5 is used to control the raising and lowering of the corresponding pantograph. By sending a pantograph raising and lowering instruction to the electromagnetic valve 5 to control the raising and lowering of the corresponding pantograph, the network control unit 3 is easy to control the pantograph, and the structure is simple and reliable.

[0058] In the embodiment, the electromagnetic valve 5 is a two-position three-way double-control electromagnetic valve 5, and the electromagnetic valve 5 is provided with a manual pantograph raising button 51 and a manual pantograph lowering button 52.

[0059] The two-position three-way double-control electromagnetic valve 5 is easy to cooperate with the pulse signal control of the network control unit 3. When receiving a pantograph raising instruction, the electromagnetic valve 51A is excited, the input port K1 and the output port K2 are connected, and the exhaust port K3 is closed, so that the pantograph is raised. When receiving a pantograph lowering instruction, the electromagnetic valve 51B is excited, the input port K1 is closed, the output port K2 and the exhaust port K3 are connected, and the pantograph is lowered. In the case of network control unit 3 failure, pantograph raising and lowering instructions cannot be sent, and the manual pantograph raising button 51 and the manual pantograph lowering button 52 on the electromagnetic valve 5 can be used to control the pantograph, thereby ensuring normal operation of the train.

[0060] In the embodiment, the local pantograph lifting unit 1 and the opposite pantograph lifting unit 2 are both self-resetting pantograph lifting buttons.

[0061] The reset pantograph lifting button used by the pantograph lifting unit can send a pantograph lifting instruction to the network control unit 3 once by pressing once and reset, which is simple in logic, easy to understand and easy for man-machine interaction.

[0062] As shown in Figure 4 The second embodiment of the present application also provides a pantograph control method of a railway vehicle, which is applied to the pantograph control device of the railway vehicle and comprises the following steps of:

[0063] When the network control unit 3 receives the local pantograph lifting instruction, the state of the local pantograph is judged, if the local pantograph is in the lifting state, a lowering instruction is sent to the local pantograph, if the local pantograph is in the lowering state, the state of the opposite pantograph is judged, if the opposite pantograph is in the lifting state, no instruction is sent, if the opposite pantograph is in the lowering state, a lifting instruction is sent to the local pantograph.

[0064] When the network control unit 3 receives the opposite pantograph lifting instruction, the state of the opposite pantograph is judged, if the opposite pantograph is in the lifting state, a lowering instruction is sent to the opposite pantograph, if the opposite pantograph is in the lowering state, the state of the local pantograph is judged, if the local pantograph is in the lifting state, no instruction is sent, if the local pantograph is in the lowering state, a lifting instruction is sent to the opposite pantograph.

[0065] During the normal operation of the railway vehicle, the key interlock box 4 is kept in the closed state, so as to ensure that the lifting and lowering instructions can be sent to the corresponding electromagnetic valves 5. The cab activation switch 6 is closed, the circuit of the pantograph control device is turned on, the local pantograph lifting unit 1 of the local car is used to control the local pantograph, and the opposite pantograph lifting unit 2 of the local car is used to control the opposite pantograph.

[0066] When the local pantograph lifting unit 1 is pressed, the network control unit 3 receives the local pantograph lifting instruction, judges the state of the local pantograph, if the local pantograph is in the lifting state, a lowering instruction is sent to the local pantograph, if the local pantograph is in the lowering state, the state of the opposite pantograph is judged, if the opposite pantograph is in the lifting state, no instruction is sent, if the opposite pantograph is in the lowering state, a lifting instruction is sent to the local pantograph, and the process of the single-time sending instruction of the local pantograph lifting unit 1 is ended.

[0067] When the pantograph raising and lowering unit 2 of the opposite end is pressed, the network control unit 3 receives the pantograph raising and lowering instruction of the opposite end, judges the state of the pantograph of the opposite end, and if the pantograph of the opposite end is in the raising state, sends a lowering instruction to the pantograph of the opposite end; if the pantograph of the opposite end is in the lowering state, judges the state of the pantograph of the self end, and if the pantograph of the self end is in the raising state, does not send an instruction, if the pantograph of the self end is in the lowering state, sends a raising instruction to the pantograph of the opposite end, and the process of the single-time sending instruction of the pantograph raising and lowering unit 2 of the opposite end ends.

[0068] The same is true for the instruction processing process of operating two pantographs of the opposite end.

[0069] Correspondingly, the embodiment further provides a railway vehicle, comprising the railway vehicle pantograph control device.

[0070] The railway vehicle provided by the embodiment can realize the structural optimization of the pantograph control circuit, improve the reliability, and guarantee the power supply safety, because the railway vehicle pantograph control device is adopted.

[0071] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.

The network control unit comprises an instruction receiving module, a state judging module and an instruction sending module; the instruction receiving module is used for receiving the local pantograph lifting instruction or the opposite pantograph lifting instruction; the state judging module is used for judging the states of the local pantograph and the opposite pantograph according to the pantograph lifting instruction, so as to determine the lifting action of the corresponding pantograph; and the instruction sending module is used for sending the lifting instruction to the corresponding pantograph of the pantograph lifting unit which sends the lifting instruction according to the lifting action. When the instruction receiving module receives the local pantograph lifting instruction, the state judging module judges the state of the local pantograph; if the local pantograph is in the lifting state, it is determined that the local pantograph is in the lowering action, and the instruction sending module sends the lowering instruction to the local pantograph; if the local pantograph is in the lowering state, the state judging module judges the state of the opposite pantograph; if the opposite pantograph is in the lifting state, it is determined that the local pantograph is in the lowering action, and the instruction sending module does not send the instruction; if the opposite pantograph is in the lowering state, it is determined that the local pantograph is in the lifting action, and the instruction sending module sends the lifting instruction to the local pantograph. When the instruction receiving module receives the opposite pantograph lifting instruction, the state judging module judges the state of the opposite pantograph; if the opposite pantograph is in the lifting state, it is determined that the opposite pantograph is in the lowering action, and the instruction sending module sends the lowering instruction to the opposite pantograph; if the opposite pantograph is in the lowering state, the state judging module judges the state of the local pantograph; if the local pantograph is in the lifting state, it is determined that the opposite pantograph is in the lowering action, and the instruction sending module does not send the instruction; if the local pantograph is in the lowering state, it is determined that the opposite pantograph is in the lifting action, and the instruction sending module sends the lifting instruction to the opposite pantograph. The state judging module judges that the pantograph is in the lowering state when a lowering-to-position signal of the pantograph is received; and the state judging module judges that the pantograph is in the lifting state when at least one of the following conditions is met: no lowering-to-position signal of the pantograph is received, a lifting-to-position signal of the pantograph is received, and a network voltage signal of the pantograph is received.
