[0050] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the specific technical solutions of the invention will be further described in detail below with reference to the accompanying drawings of the embodiments of this disclosure. The following embodiments are used to illustrate this disclosure, but are not intended to limit the scope of this disclosure.

[0051] This disclosure provides a fan control device, such as... Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the structure of a fan control device according to an exemplary embodiment. The device includes:

[0052] Control component 11, connected to the fan assembly 20, is used to control the wind speed of the fan assembly 20;

[0053] The control component 11 includes: a plurality of control lines 111;

[0054] Each of the control lines 111 includes at least:

[0055] First controlled switch 1111;

[0056] The remote controller 1112 is connected to the controlled end of the first controlled switch 1111 and is used to control the first controlled switch 1111 to close and conduct the control line 11; wherein, the different on / off states of the plurality of control lines 11 correspond to the different wind speed states of the fan assembly 20.

[0057] The fan control device shown in this embodiment can be applied within a fan assembly to automatically switch between multiple different wind speed states of the fan assembly. Here, the fan assembly can be a fan assembly equipped with an asynchronous motor; for example, the fan assembly can be a cooling fan of a high-speed train.

[0058] The wind turbine control device includes: a control component;

[0059] The control component is connected to the fan assembly, and the control component is used to control the speed of the motor in the fan assembly, thereby achieving the effect of increasing the wind speed of the fan assembly.

[0060] It should be noted that, in order to achieve speed regulation of the fan assembly in a simple and effective way, the motor speed can be changed by altering the number of stator pole pairs within the fan assembly.

[0061] The control component shown in this embodiment can be connected to the stator winding of the motor in the fan assembly. By changing the connection method of the stator winding in the motor, the number of pole pairs of the rotating magnetic field of the stator in the motor can be changed, thereby changing the speed of the motor.

[0062] The control component includes: multiple control lines;

[0063] Here, one end of the control circuit is connected to the stator winding in the wind turbine assembly. It can be understood that the control assembly also includes a power supply assembly, and the other end of the control circuit is connected to the power supply assembly.

[0064] Each of the control circuits includes: a first controlled switch and a remote controller;

[0065] The first controlled switch is connected in series in the control circuit, and the remote controller is connected to the controlled terminal of the first controlled switch. The remote controller controls the first controlled switch to close or open by sending a control signal to the controlled terminal of the first controlled switch, thereby turning the control circuit on or off.

[0066] It is understood that the first terminal of the first controlled switch is connected to the power conversion component, the second terminal of the first controlled switch is connected to the stator winding through the switching component, and the remote controller controls the closing of the first controlled switch to conduct the control circuit.

[0067] It should be noted that the power conversion component is an electrical device that changes the voltage, frequency, number of phases, or other electrical quantities and characteristics of a power system, such as a converter, rectifier, or boost converter. The first terminal of the first controlled switch is connected to the output terminal of the power conversion component to receive the signal output by the power conversion component.

[0068] The switching component refers to electrical equipment, control circuits, etc., that switch the connection mode of the stator windings. It can be understood that when the first controlled switch is closed, the control circuit is activated; at this time, based on the activation of the control circuit, the switching component can be used to switch the connection mode of the stator windings, thereby changing the speed of the motor.

[0069] like Figure 2 As shown, Figure 2 This is a schematic diagram of the internal circuit structure of a remote controller according to an exemplary embodiment; the remote controller includes: a first control button RC_ON, a second control button RC_OFF and a third control button (not shown in the figure), a first input terminal L / +, a second input terminal N / -, a built-in alarm contact and a built-in auxiliary contact.

[0070] The first input terminal L / + is connected to the first power supply component, and the external contact points of the first control button RC_ON and the second control button RC_OFF are respectively connected to the first power supply component 13. The first power supply component 13 is used to input positive voltage signals (e.g., +110V electrical signals) to the first input terminal L / +, the external contact points of the first control button RC_ON and the second control button RC_OFF.

[0071] The second input terminal N / - is connected to the second power supply component 14; the second power supply component 14 is used to input a negative voltage signal (e.g., an electrical signal of -110V) to the second input terminal N / -.

[0072] like Figure 3 As shown, Figure 3 This is a schematic diagram of the external circuit structure of a remote controller according to an exemplary embodiment. The external contact point of the first control button RC_ON of the remote controller 1112, which has multiple control branches, is connected to the first power supply component 13.

[0073] It should be noted that the remote controller is not affected by voltage. During the entire control process, even if the connection between the external contact of the first control button RC-ON in the remote controller and the first power supply component is occasionally disconnected, it will not affect its normal control of the first controlled switch.

[0074] In this embodiment of the present disclosure, the opening and closing state of the first controlled switch in each control line can be controlled by a remote controller in each control line, so as to realize the control of the on and off state of multiple control lines.

[0075] Considering that the different on / off states of multiple control circuits will affect the connection method of the stator windings inside the motor, thereby affecting the number of pole pairs of the rotating magnetic field of the stator inside the motor, and further affecting the speed of the motor.

[0076] Therefore, in this embodiment, the opening and closing state of the first controlled switch in the control circuit can be controlled by each remote controller, so that the connection mode of the stator winding in the motor of the wind turbine assembly can be switched by changing the on and off state of multiple control circuits, thereby completing the switching control of different wind speed states of the wind turbine assembly.

[0077] Optionally, such as Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the principle of one such control component according to an exemplary embodiment. The control circuit 111 includes at least:

[0078] The second controlled switch 1113 is connected in series with the first controlled switch 1111;

[0079] The device includes:

[0080] The control unit is connected to the controlled end of the second controlled switch 1113 of the plurality of control lines 111 respectively, and is used to control the second controlled switch 1113 to close and send control commands to the remote controller;

[0081] The remote controller is used to control the control line where the second controlled switch 1113 is located after receiving the control command.

[0082] In this embodiment of the disclosure, the control circuit includes: a second controlled switch;

[0083] The second controlled switch is connected in series with the first controlled switch in the control circuit.

[0084] It is understood that the first terminal of the first controlled switch is connected to the power conversion component, the second terminal of the first controlled switch is connected to the first terminal of the second controlled switch, and the second terminal of the second controlled switch is connected to the stator winding.

[0085] The control component includes: a control unit;

[0086] It should be noted that the control unit may be a device that controls the power conversion component (e.g., a converter).

[0087] The control unit is connected to the controlled terminal of the second controlled switch in the multiple control circuits respectively, and the control unit is used to control the opening and closing state of the multiple second controlled switches.

[0088] Considering that the different on / off states of the multiple control lines correspond to the different wind speed states of the wind turbine assembly, in this embodiment of the present disclosure, the control unit can control the closing of the second controlled switch of at least one of the multiple control lines and send control commands to the remote controller in the at least one control line;

[0089] After receiving the control command, the remote controller in the at least one control line controls the first controlled switch in the at least one control line to close, so that the first controlled switch and the second controlled switch in the at least one control line are both in the closed state, and the at least one control line is in the conducting state, so as to realize the switching of different wind speed states of the wind turbine components.

[0090] Optionally, such as Figure 4 As shown, the plurality of control lines 111 include: a first control line 111a and a second control line 111b;

[0091] The control component 11 includes:

[0092] The third controlled switch 1114 is connected to the control unit at its controlled end. The first end of the third controlled switch 1114 is connected in parallel with the second controlled switch 1113 of the first control line 111a, and the second end of the third controlled switch 1114 is short-circuited.

[0093] In this embodiment of the disclosure, the control component includes: a first control line and a second control line;

[0094] It is understood that both the first control circuit and the second control circuit include: a first controlled switch, a second controlled switch, and a remote controller; wherein the first controlled switch and the second controlled switch are connected in series, the remote controller is connected to the controlled terminal of the first controlled switch, and the controlled terminal of the second controlled switch is connected to the control unit of the control component.

[0095] The control component includes: a third controlled switch;

[0096] The controlled terminal of the third controlled switch is connected to the control unit, and the control unit controls the opening and closing state of the third controlled switch.

[0097] The first terminal of the third controlled switch is connected in parallel with the second controlled switch in the first control circuit, and the second terminal of the third controlled switch is short-circuited.

[0098] It should be noted that, within the first control circuit, the first end of the second controlled switch is connected to the second end of the first controlled switch, the second end of the second controlled switch is connected to the end of the stator winding, the first end of the third controlled switch is connected to the second end of the second controlled switch, and the second end of the third controlled switch is short-circuited.

[0099] In the second control circuit, the first end of the second controlled switch is connected to the second end of the first controlled switch, and the second end of the second controlled switch is connected to the tail end of the stator winding.

[0100] It should be noted that, as Figure 5 As shown, Figure 5 This is a schematic diagram of the internal wiring principle of a motor running at a first speed according to an exemplary embodiment; when the first control line is on, the second control line is off and the third controlled switch is off, the motor runs at the first speed, and the stator windings inside the motor are connected in series in a Y-shape, at which time the number of pole pairs of the stator rotating magnetic field is 2.

[0101] like Figure 6 As shown, Figure 6 This is a schematic diagram illustrating the internal wiring principle of a motor operating at a second speed according to an exemplary embodiment. When the first control line is disconnected, the second control line is connected, and the third controlled switch is closed, the motor operates at the second speed. The stator windings inside the motor are connected in parallel YY type, and the number of pole pairs of the stator rotating magnetic field is 1.

[0102] Here, the first rotational speed is less than the second rotational speed.

[0103] It is understood that by controlling the opening and closing states of the first controlled switch, the second controlled switch, and / or the third controlled switch, the wiring method of the stator winding in the motor can be changed, thereby changing the number of pole pairs of the stator rotating magnetic field and thus achieving the effect of changing the motor speed.

[0104] Optionally, the first controlled switch is a circuit breaker; the second and third controlled switches are contactors.

[0105] In this embodiment of the disclosure, the first controlled switch may be a circuit breaker, and the second and third controlled switches may be contactors.

[0106] It should be noted that the circuit breaker refers to a switching device capable of closing, carrying and switching current under normal circuit conditions, and capable of closing, carrying and switching current under abnormal circuit conditions within a specified time.

[0107] It should be noted that in the relevant technology, the circuit breaker can be opened automatically, but the circuit breaker needs to be closed manually. This means that during the switching of wind speed status of the wind turbine components, it is necessary to manually control the closing of the circuit breaker in the control circuit. On the one hand, since the switching process requires human control, human error may occur during the entire switching process, increasing the failure rate of the components. On the other hand, manually controlling the closing of the circuit breakers in different control circuits is cumbersome and has low reliability.

[0108] Therefore, in this embodiment of the present disclosure, a remote controller is used to automatically close the circuit breaker connected to it, thereby realizing the automatic closing of the circuit breaker.

[0109] For example, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the installation layout of a remote controller according to an exemplary embodiment. Within the control assembly, the remote controller 1112 and the circuit breaker 1111a are fixed together by a detachable connection, for example, the connection between the remote controller and the circuit breaker can be achieved by a snap-fit ​​connection.

[0110] Furthermore, the remote controller 1112 and the circuit breaker 1111a can be fixed on the guide rail 21 of the EMU. In order to limit the position of the circuit breaker 1111a and the remote controller 1112 on the guide rail 21, fixing baffles 22 can be installed on both sides of the circuit breaker 1111a and the remote controller 1112.

[0111] The contactor is a device that can quickly switch between DC and AC main circuits and frequently connect or disconnect high-current control circuits. The power conversion component (e.g., a converter) is connected to the coil of the contactor, and the control unit controls the converter to provide an electrical signal to the coil. When the coil of the contactor is energized, the coil current generates a magnetic field, which drives the contacts of the contactor to close under the action of the magnetic field.

[0112] In this embodiment of the disclosure, the control unit supplies power to the coils of contactors in different control lines within the control component by controlling the power conversion component, so that the contactors in different control lines are closed; the remote controller can automatically close the circuit breaker connected to it after receiving the control command from the control unit, so that the circuit breaker is automatically closed, so that multiple control lines within the control component are in different on / off states, thereby realizing automatic switching of different wind speed states of the wind turbine component.

[0113] Optionally, the remote controller includes:

[0114] A status indication unit is used to output the current status information of the remote controller;

[0115] The current status information is used at least to help the control unit determine whether to send the control command to the remote controller.

[0116] In this embodiment of the disclosure, the remote controller includes: a status indication unit;

[0117] Here, the status indication unit may be an indicator light or an indication signal output port, etc. This disclosure does not limit this.

[0118] The status indication unit can be used to output the current status information of the remote controller.

[0119] It should be noted that the remote controller has multiple different operating states, and the control of the circuit breaker by the remote controller may differ when the remote controller is in different operating states.

[0120] The current status information of the remote controller output by the status indication unit is used to indicate at least whether the remote controller can perform remote control operation on the circuit breaker.

[0121] The current status information can be used by the control unit to determine whether the remote controller can remotely control the circuit breaker based on the current status information of the remote controller, thereby determining whether it is necessary to send control commands to the remote controller.

[0122] It should be noted that if the current status information of the remote controller indicates that the remote controller cannot perform remote control operation on the circuit breaker, the remote controller cannot perform any operation on the circuit breaker even if the control unit sends control commands to the remote controller.

[0123] For example, taking the status indication unit as an indicator light, as shown in Table 1, Table 1 is an information correspondence table of the indication status and working status of a remote controller.

[0124] Table 1. Correspondence between indication status and working status of a remote controller.

[0125]

[0126] It is understood that the remote controller can remotely close the circuit breaker only when the indicator light is in a solid green or slow red flashing state.

[0127] This embodiment of the disclosure sets a status indicator element on the remote controller and uses the status indicator element to output the current status information of the remote controller, so that the control unit can determine whether to send a control command to the remote controller based on the current status information of the remote controller, thereby reducing the sending of invalid control commands.

[0128] This disclosure also provides a control method. Figure 8 This is a flowchart illustrating a control method according to an exemplary embodiment, such as... Figure 8 As shown, the method includes:

[0129] Step S101: The control unit sends a control command to the remote controller in the target control line and controls the second controlled switch of the target control line to close; the target control line is any one of multiple control lines.

[0130] In step S102, in response to the control command, the remote controller controls the first controlled switch in the target control line to close, thereby connecting the target control line to the wind turbine assembly; wherein, the different on / off states of the plurality of control lines correspond to the different wind speed states of the wind turbine assembly.

[0131] The control method shown in this disclosure can be applied to the fan control device shown in one or more of the above embodiments. By utilizing the cooperation between the various components in the fan control device, the automatic switching of different wind speed states of the fan components can be achieved.

[0132] In step S101, the target control line may be at least one of the multiple control lines of the wind turbine control device;

[0133] Since the different on / off states of the multiple control lines correspond to the different wind speed states of the wind turbine assembly, the on / off states of the multiple control lines corresponding to the target wind speed state of the wind turbine assembly can be obtained, and at least one control line in the conducting state when the wind turbine assembly is in the target wind speed state can be identified as the target control line.

[0134] The control unit in the wind turbine control device sends control commands to the remote controller in the target control line, and controls the second controlled switch in the target control line to close through the control unit.

[0135] Here, the sequence in which the control unit sends control commands to the remote controller within the target control line and controls the closing of the second controlled switch within the target control line can be adjusted according to the actual situation; alternatively, the control unit can control the closing of the second controlled switch within the target control line while simultaneously sending control commands to the remote controller within the target control line. This disclosure does not limit this aspect.

[0136] In step S102, after receiving the control command, the remote controller can control the first controlled switch in the target control line to close, so that the target control line is in a conducting state, thereby realizing the switching of the target wind speed state of the wind turbine component.

[0137] This embodiment of the present disclosure can control the on / off state of the target control line in the multiple control lines through the control unit and the remote controller in the multiple control lines, thereby switching the connection mode of the stator winding in the motor of the wind turbine assembly and completing the switching control of different wind speed states of the wind turbine assembly.

[0138] Optionally, the method includes:

[0139] The control unit controls the second controlled switch of the first control line to close and sends control commands to the remote controller of the first control line.

[0140] In response to the control command, the remote controller controls the first controlled switch of the first control line to close, and controls the fan assembly to operate at a first wind speed.

[0141] In this embodiment of the disclosure, the control component includes a first control circuit and a second control circuit;

[0142] The control unit can control the closing of the second controlled switch in the first control line and send the control command to the remote controller in the first control line.

[0143] After receiving the control command, the remote controller in the first control line controls the first controlled switch in the first control line to close. At this time, both the first controlled switch and the second controlled switch in the first control line are in the closed state, and the first control line is connected.

[0144] When the first control circuit is on, the second control circuit is off, and the third controlled switch is off, the stator windings inside the motor are connected in series in a Y-shape, the number of pole pairs of the stator rotating magnetic field is 2, the motor runs at a first speed, thereby causing the fan assembly to run at a first wind speed.

[0145] Here, the first wind speed state can be a low-speed operating state.

[0146] Optionally, the method includes:

[0147] The control unit controls the third controlled switch of the first control line and the second controlled switch of the second control line to close, and sends control commands to the remote controller of the second control line.

[0148] In response to the control command, the remote controller controls the first controlled switch of the second control circuit to close, and controls the fan assembly to operate at a second wind speed; wherein the second wind speed is higher than the first wind speed.

[0149] In this embodiment of the disclosure, since the first terminal of the third controlled switch is connected in parallel with the second controlled switch in the first control circuit, the second terminal of the third controlled switch is short-circuited.

[0150] The control unit can control the closing of the third controlled switch of the first control line and the second controlled switch of the second control line, and the control unit can send the control command to the remote controller in the second control line;

[0151] After receiving the control command, the remote controller in the second control line controls the first controlled switch in the second control line to close. At this time, both the first controlled switch and the second controlled switch in the second control line are in the closed state, and the second control line is connected.

[0152] When the first control line is disconnected, the second control line is connected, and the third controlled switch is closed, the stator windings inside the motor are connected in parallel YY type, the number of magnetic pole pairs of the stator rotating magnetic field is 1, the motor runs at the second speed, thereby causing the fan assembly to run at the second wind speed.

[0153] Here, the first wind speed state can be the high-speed operating state.

[0154] This embodiment of the invention allows control of the opening and closing states of the first controlled switch, the second controlled switch, and the third controlled switch within the first control line and / or the second control line via a control unit and a remote controller. This changes the wiring configuration of the stator windings within the motor, thereby altering the number of pole pairs in the stator rotating magnetic field, changing the motor speed, and achieving the effect of automatically switching the wind speed of the fan assembly.

[0155] Optionally, sending control commands to the remote controller via the control unit includes:

[0156] Obtain the current status information of the remote controller from the status indication unit of the remote controller;

[0157] When the current status information of the remote controller indicates that the remote controller is in a preset state, the control unit sends the control command to the remote controller.

[0158] In this embodiment of the disclosure, the control unit can obtain the current status information of the remote controller through the status indication unit of the remote controller.

[0159] Here, the status indication unit can output the current status information of the remote controller, which is at least used to indicate whether the remote controller can perform remote control operation on the circuit breaker.

[0160] Based on the current status information of the remote controller, it is determined whether the remote controller is in a preset state; if the current status information of the remote controller indicates that the remote controller is in a preset state, the control unit can send a control command to the remote controller so that the remote controller can control the circuit breaker connected to it to conduct after receiving the control command.

[0161] Here, the preset state can be set according to the actual situation, as long as the remote controller can perform remote control closing operation on the circuit breaker when the remote controller is in the preset state.

[0162] If the current status information of the remote controller indicates that the remote controller is not in a preset state, it means that the remote controller cannot perform remote control operation on the circuit breaker at present. The control unit can monitor the current status information output by the status indication unit of the remote controller until the current status information output by the status indication unit indicates that the remote controller is in a preset state, and then send control commands to the remote controller, thereby effectively reducing the sending of invalid control commands.
