背景技术Background technique

轨道车辆在走行轨上行驶时，如果需要对其上的动力电池进行充电，则轨道车辆需行驶至充电站，以对动力电池进行充电。然而，由于轨道车辆到达充电站的方向并不是固定的，例如，对于东西向的充电站，轨道车辆到达该充电站时，行驶方向可能是自西向东，也可能是自东向西，因此在充电时可能会出现充电正负极接反的情况，进而可能导致动力电池的损坏，影响车辆的安全性。When a rail vehicle is traveling on a moving track, if it needs to charge its power battery, the rail vehicle needs to travel to a charging station to charge the power battery. However, the direction in which rail vehicles reach the charging station is not fixed. For example, for a east-west charging station, when the rail vehicle arrives at the charging station, the driving direction may be from west to east or east to west. When charging, the positive and negative charges may be reversed, which may cause damage to the power battery and affect the safety of the vehicle.

作为一个实施例，如图4、图5所示，轨道车辆的充电控制装置100还包括电压检测器40。电压检测器40可设置在轨道车辆上，电压检测器40的一端与第一节点a相连，电压检测器40的另一端与第二节点b相连，电压检测器40用于在轨道车辆停靠在充电站，且控制器30在预设时间内未获取到行车方向时，检测充电装置直流侧的输出电压极性。应当理解，充电装置用于给轨道车辆提供其充电所需的直流电，充电装置直流侧即为与取流装置10相连的，可输出直流电的一侧。As an embodiment, as shown in FIGS. 4 and 5, the charging control device 100 for a rail vehicle further includes a voltage detector 40. The voltage detector 40 may be provided on a rail vehicle. One end of the voltage detector 40 is connected to the first node a, and the other end of the voltage detector 40 is connected to the second node b. The voltage detector 40 is used to charge the rail vehicle when it is parked. When the controller 30 does not obtain a driving direction within a preset time, the controller 30 detects the polarity of the output voltage on the DC side of the charging device. It should be understood that the charging device is used to provide the DC vehicle with the DC power required for charging, and the DC side of the charging device is the side that is connected to the current taking device 10 and can output DC power.

具体地，充电装置的充电槽和充电器之间可连接有接触器，该接触器为常开接触器。当轨道车辆停靠在充电站台，轨道车辆的充电刀片与充电槽连接后，如果控制器30在一定时间内未获取到行车方向，则控制器30可向充电装置发送行车方向信号异常信息，以使充电装置吸合接触器。此时，控制器30还用于获取充电装置直流侧的输出电压极性，并在输出电压极性为第一极性时，确定第一取流器11与充电装置的第一极相连，第二取流器12与充电装置的第二极相连，以及在输出电压的极性为第二极性时，确定第一取流器11与充电装置的第二极相连，第二取流器12与充电装置的第一极相连。Specifically, a contactor may be connected between the charging slot of the charging device and the charger, and the contactor is a normally open contactor. When the rail vehicle is docked at the charging station and the charging blade of the rail vehicle is connected to the charging slot, if the controller 30 does not obtain the driving direction within a certain time, the controller 30 may send the driving direction signal abnormal information to the charging device so that The charging device engages the contactor. At this time, the controller 30 is further configured to obtain the polarity of the output voltage on the DC side of the charging device, and determine that the first current collector 11 is connected to the first pole of the charging device when the output voltage polarity is the first polarity. The two current collectors 12 are connected to the second pole of the charging device, and when the polarity of the output voltage is the second polarity, it is determined that the first current collector 11 is connected to the second pole of the charging device, and the second current collector 12 Connected to the first pole of the charging device.

在一个示例中，电压检测器40可采用电压霍尔传感器。In one example, the voltage detector 40 may employ a voltage Hall sensor.

作为一个实施例，在第一开关组件21或第二开关组件22闭合后，电压检测器40还获取动力电池的电压极性，控制器30还用于根据动力电池的电压极性对第一开关组件21或第二开关组件22进行控制，以对动力电池与充电装置准确连接提供双重保证。As an embodiment, after the first switch component 21 or the second switch component 22 is closed, the voltage detector 40 further acquires the voltage polarity of the power battery, and the controller 30 is further configured to perform a voltage switch on the first switch according to the voltage polarity of the power battery. The component 21 or the second switch component 22 controls to provide a double guarantee for the accurate connection of the power battery and the charging device.

具体地，在一个示例中，如果控制器30根据行车方向控制第一开关组件21闭合之后，接收到电压检测器40获取到的动力电池的电压极性，且该动力电池的电压极性与行车方向矛盾，则控制器30控制第一开关组件21断开，充电结束；同理，如果控制器30根据行车方向控制第二开关组件22闭合之后，接收到电压检测器40获取到的动力电池的电压极性，且该电压极性与行车方向矛盾，则控制器30控制第二开关组件22断开，充电结束。Specifically, in an example, if the controller 30 controls the first switch assembly 21 to be closed according to the driving direction, the controller 30 receives the voltage polarity of the power battery obtained by the voltage detector 40, and the voltage polarity of the power battery and the driving If the directions are inconsistent, the controller 30 controls the first switch assembly 21 to open, and the charging ends. Similarly, if the controller 30 controls the second switch assembly 22 to close according to the driving direction, the controller 30 receives the power battery obtained by the voltage detector 40. If the voltage polarity is inconsistent with the driving direction, the controller 30 controls the second switch assembly 22 to be turned off, and the charging ends.

可以理解，如果电压极性与行车方向不矛盾，则允许充电，控制器30可向充电装置发送允许充电指令，以便充电装置吸合接触器，开始充电。It can be understood that if the voltage polarity does not contradict the driving direction, charging is allowed, and the controller 30 may send a charging permission instruction to the charging device, so that the charging device engages the contactor and starts charging.

在另一个示例中，当控制器30根据充电装置直流侧的输出电压极性控制第一开关组件21闭合之后，充电装置可断开充电槽与充电器之间的接触器，若控制器30接收到电压检测器40获取到的动力电池的电压极性，且该动力电池的电压极性与充电装置直流侧的输出电压极性不一致，则控制器30控制第一开关组件21断开，充电结束；同理，如果控制器30根据充电装置直流侧的输出电压极性控制第二开关组件22闭合之后，充电装置可断开充电槽与充电器之间的接触器，若控制器30接收到电压检测器40获取到的动力电池的电压极性，且该电压极性与充电装置直流侧的输出电压极性不一致，则控制器30控制第二开关组件22断开，充电结束。In another example, after the controller 30 controls the first switch assembly 21 to close according to the output voltage polarity of the DC side of the charging device, the charging device may open the contactor between the charging tank and the charger. The voltage polarity of the power battery obtained by the voltage detector 40 is inconsistent with the output voltage polarity of the DC side of the charging device, the controller 30 controls the first switch assembly 21 to be turned off, and the charging is completed. ; Similarly, if the controller 30 controls the second switch assembly 22 to be closed according to the output voltage polarity of the DC side of the charging device, the charging device may open the contactor between the charging tank and the charger, if the controller 30 receives the voltage The voltage polarity of the power battery obtained by the detector 40 is inconsistent with the output voltage polarity of the DC side of the charging device, the controller 30 controls the second switch assembly 22 to be turned off, and the charging ends.

在本申请的实施例中，参照图4、图5，开关电路20和取流装置10之间还可连接熔断器，以对充电控制装置100进行保护。In the embodiment of the present application, referring to FIG. 4 and FIG. 5, a fuse may be further connected between the switching circuit 20 and the current taking device 10 to protect the charging control device 100.

下面结合图2-图6，描述本申请实施例的轨道车辆的充电控制装置100的工作原理。The working principle of the charging control device 100 for a rail vehicle according to an embodiment of the present application is described below with reference to FIGS. 2 to 6.

如图2所示，当轨道车辆向右行驶时，行车方向信号规定为01，轨道车辆在充电站充电时，第一取流器11连接至该充电站的充电装置的正极，第二取流器12连接至充电装置的负极。如图3所示，当轨道车辆向左行驶时，行车方向信号规定为02，轨道车辆在充电站充电时，第二取流器12连接至该充电站的充电装置的正极，第一取流器11连接至充电装置的负极。As shown in Figure 2, when the rail vehicle is driving to the right, the driving direction signal is specified as 01. When the rail vehicle is charging at the charging station, the first current collector 11 is connected to the positive electrode of the charging device of the charging station, and the second current is taken. The charger 12 is connected to the negative electrode of the charging device. As shown in FIG. 3, when the rail vehicle is driving to the left, the driving direction signal is specified as 02. When the rail vehicle is charged at the charging station, the second current collector 12 is connected to the positive electrode of the charging device of the charging station, and the first current is taken. The charger 11 is connected to the negative electrode of the charging device.

可以看出，当轨道车辆的行车方向变化后，在充电站充电时，充电站的充电装置正负极没有发生变化，但是流至轨道车辆上的第一取流器11和第二取流器12的电流极性发生了变化，因此为保证充电装置的极性与动力电池正负极性一致，需要在轨道车辆上进行换流。It can be seen that when the traveling direction of the rail vehicle changes, the positive and negative poles of the charging device of the charging station do not change when charging at the charging station, but they flow to the first and second

current collectors

11 and 2 of the rail vehicle. The current polarity of 12 has changed, so in order to ensure that the polarity of the charging device is consistent with the positive and negative polarity of the power battery, it is necessary to perform commutation on the rail vehicle.

在一个实施例中，如图4所示，当轨道车辆右行，即行车方向信号为01时，控制器30控制第一开关KM1和第二开关KM2闭合，电压检测器40采集到的是正电压，充电装置的直流侧供电端与动力电池极性一致，可以充电。当轨道车辆左行，即行车方向信号为02时，控制器30控制第三开关KM3和第四开关KM4闭合，电压检测器40采集到的电压是0，充电装置的直流侧供电端与动力电池极性一致，可以充电。In one embodiment, as shown in FIG. 4, when the rail vehicle is driving to the right, that is, the driving direction signal is 01, the controller 30 controls the first switch KM1 and the second switch KM2 to be closed, and the positive voltage is collected by the voltage detector 40. , The DC-side power supply end of the charging device has the same polarity as the power battery and can be charged. When the rail vehicle goes to the left, that is, the driving direction signal is 02, the controller 30 controls the third switch KM3 and the fourth switch KM4 to be closed, the voltage collected by the voltage detector 40 is 0, the DC-side power supply terminal of the charging device and the power battery The polarity is consistent and can be charged.

具体地，当轨道车辆接收到到站信号后，轨道车辆的CCU(Central Control Unit，中央控制单元)发送行车方向信号给控制器30。如果行车方向信号为01，即轨道车辆右行，控制器30控制第一开关KM1和第二开关KM2闭合，此时电压检测器40采集到的电压信号是动力电池当前电压。若电压检测器40采集到正电压，则控制器30可向充电装置发送允许充电指令，以便充电装置的直流输出侧接触器吸合，输出电压进行充电；若电压检测器40采集到的电压是0，则说明动力电池极性与充电装置极性不一致，控制器30控制第一开关KM1和第二开关KM2断开，当然也可向充电装置发送禁止充电指令，以禁止充电。Specifically, after the rail vehicle receives the arrival signal, the CCU (Central Control Unit) of the rail vehicle sends a driving direction signal to the controller 30. If the driving direction signal is 01, that is, the right side of the rail vehicle, the controller 30 controls the first switch KM1 and the second switch KM2 to be closed. At this time, the voltage signal collected by the voltage detector 40 is the current voltage of the power battery. If the positive voltage is collected by the voltage detector 40, the controller 30 may send a charging permission instruction to the charging device so that the DC output-side contactor of the charging device attracts and the output voltage is charged; if the voltage collected by the voltage detector 40 is 0, it means that the polarity of the power battery and the polarity of the charging device are inconsistent. The controller 30 controls the first switch KM1 and the second switch KM2 to be turned off. Of course, a charging prohibition instruction can also be sent to the charging device to prohibit charging.

如果行车方向信号为02，即轨道车辆左行，控制器30控制第三开关KM3和第四开关KM4闭合，此时电压检测器40采集到的电压信号是动力电池当前电压。若电压检测器40采集到的电压是0，则控制器30可向充电装置发送允许充电指令，以便充电装置的直流输出侧接触器吸合，输出电压进行充电；若电压检测器40采集到正电压，则说明动力电池极性与充电装置极性不一致，控制器30控制第三开关KM3和第四开关KM4断开，当然也可向充电装置发送禁止充电指令，以禁止充电。If the driving direction signal is 02, that is, the left side of the rail vehicle, the controller 30 controls the third switch KM3 and the fourth switch KM4 to be closed. At this time, the voltage signal collected by the voltage detector 40 is the current voltage of the power battery. If the voltage collected by the voltage detector 40 is 0, the controller 30 may send a charging permission instruction to the charging device, so that the DC output-side contactor of the charging device attracts and the output voltage is charged; if the voltage detector 40 collects a positive voltage, The voltage indicates that the polarity of the power battery is different from the polarity of the charging device. The controller 30 controls the third switch KM3 and the fourth switch KM4 to be turned off. Of course, it is also possible to send a charging prohibition instruction to the charging device to prohibit charging.

当轨道车辆停靠在充电站，CCU故障未发送出行车方向信号时，例如，控制器30在预设时间(如3s)内未接收到行车方向信号时，控制器30暂不对第一开关组件21和第二开关组件22进行控制，充电装置直流侧的接触器吸合先行输出，电压检测器40采集到电压信号(即充电装置直流侧的输出电压极性)后，若为正，则控制器30控制第一开关KM1和第二开关KM2闭合，若为负，则控制器30控制第三开关KM3和第四开关KM4闭合。当然，在第一开关KM11和第二开关KM2，或者，第三开关KM3和第四开关KM4闭合后，电压检测器40还检测动力电池的电压极性，以进行双重判断。When the rail vehicle is parked at the charging station and the driving direction signal is not sent when the CCU fails, for example, when the controller 30 does not receive the driving direction signal within a preset time (such as 3s), the controller 30 does not temporarily switch the first switch assembly 21 Controlled with the second switch assembly 22, the contactor on the DC side of the charging device pulls in and outputs first, and the voltage detector 40 collects the voltage signal (that is, the output voltage polarity of the DC side of the charging device), and if it is positive, the controller 30 controls the first switch KM1 and the second switch KM2 to be closed. If negative, the controller 30 controls the third switch KM3 and the fourth switch KM4 to be closed. Of course, after the first switch KM11 and the second switch KM2, or the third switch KM3 and the fourth switch KM4 are closed, the voltage detector 40 also detects the voltage polarity of the power battery for double judgment.

在另一个实施例中，如图5所示，当轨道车辆右行，即行车方向信号为01时，控制器30控制第一单刀双掷开关SW1的不动端与第一动端连接，第二单刀双掷开关SW2的不动端与第二动端连接，电压检测器40采集到的是正电压，充电装置的直流侧供电端与动力电池极性一致，可以充电。当轨道车辆左行，即行车方向信号为02时，控制器30控制第一单刀双掷开关SW1的不动端与第二动端连接，第二单刀双掷开关SW2的不动端与第一动端连接，电压检测器40采集到的电压是0，充电装置的直流侧供电端与动力电池极性一致，可以充电。In another embodiment, as shown in FIG. 5, when the rail vehicle is driving to the right, that is, the driving direction signal is 01, the controller 30 controls the fixed end of the first SPDT switch SW1 to be connected to the first moving end. The fixed ends of the two single-pole double-throw switches SW2 are connected to the second moving end. The positive voltage is collected by the voltage detector 40. The DC-side power supply terminal of the charging device has the same polarity as the power battery and can be charged. When the rail vehicle is traveling to the left, that is, the driving direction signal is 02, the controller 30 controls the fixed end of the first SPDT switch SW1 to be connected to the second moving end, and the fixed end of the second SPDT switch SW2 to the first The moving end is connected. The voltage collected by the voltage detector 40 is 0. The DC-side power supply end of the charging device has the same polarity as the power battery and can be charged.

具体地，当轨道车辆接收到到站信号后，轨道车辆的CCU(Central Control Unit，中央控制单元)发送行车方向信号给控制器30。如果行车方向信号为01，即轨道车辆右行，控制器30控制第一单刀双掷开关SW1的不动端与第一动端连接，第二单刀双掷开关SW2的不动端与第二动端连接，此时电压检测器40采集到的电压信号是动力电池当前电压。若电压检测器40采集到正电压，则控制器30可向充电装置发送允许充电指令，以便充电装置的直流输出侧接触器吸合，输出电压进行充电；若电压检测器40采集到电压为0，则说明动力电池极性与充电装置极性不一致，控制器30控制第一单刀双掷开关SW1的不动端与第一动端之间的连接断开，第二单刀双掷开关SW2的不动端与第二动端之间的连接断开，当然也可向充电装置发送禁止充电指令，以禁止充电。Specifically, after the rail vehicle receives the arrival signal, the CCU (Central Control Unit) of the rail vehicle sends a driving direction signal to the controller 30. If the driving direction signal is 01, that is, the right side of the rail vehicle, the controller 30 controls the fixed end of the first SPDT switch SW1 to be connected to the first moving end, and the fixed end of the second SPDT switch SW2 to the second moving Terminal, the voltage signal collected by the voltage detector 40 at this time is the current voltage of the power battery. If the positive voltage is detected by the voltage detector 40, the controller 30 may send a charging permission instruction to the charging device so that the DC output side contactor of the charging device attracts and the output voltage is charged; if the voltage detected by the voltage detector 40 is 0 , It means that the polarity of the power battery is not the same as the polarity of the charging device, the controller 30 controls the connection between the fixed end of the first single-pole double-throw switch SW1 and the first moving end to be disconnected, and the The connection between the moving end and the second moving end is disconnected. Of course, a charging prohibition instruction can also be sent to the charging device to prohibit charging.

如果行车方向信号为02，即轨道车辆左行，控制器30控制第一单刀双掷开关SW1的不动端与第二动端连接，第二单刀双掷开关SW2的不动端与第一动端连接，此时电压检测器40采集到的电压信号是动力电池当前电压。若电压检测器40采集到电压0，则控制器30可向充电装置发送允许充电指令，以便充电装置的直流输出侧接触器吸合，输出电压进行充电；若电压检测器40采集到正电压，则说明动力电池极性与充电装置极性不一致，控制器30控制第一单刀双掷开关SW1的不动端与第二动端之间的连接断开，第二单刀双掷开关SW2的不动端与第一动端之间的连接断开，当然也可向充电装置发送禁止充电指令，以禁止充电。If the driving direction signal is 02, that is, the left side of the rail vehicle, the controller 30 controls the fixed end of the first SPDT switch SW1 to be connected to the second moving end, and the fixed end of the second SPDT switch SW2 to the first moving Terminal, the voltage signal collected by the voltage detector 40 at this time is the current voltage of the power battery. If the voltage detector 40 collects a voltage of 0, the controller 30 may send a charging permission instruction to the charging device, so that the DC output-side contactor of the charging device engages and the output voltage is charged; if the voltage detector 40 collects a positive voltage, It means that the polarity of the power battery is not the same as the polarity of the charging device. The controller 30 controls the connection between the fixed end of the first single-pole double-throw switch SW1 and the second moving end to be disconnected, and the second single-pole double-throw switch SW2 does not move. The connection between the mobile terminal and the first mobile terminal is disconnected. Of course, a charging prohibition instruction may also be sent to the charging device to prohibit charging.

当轨道车辆停靠在充电站，CCU故障未发送出行车方向信号时，例如，控制器30在预设时间(如3s)内未接收到行车方向信号时，控制器30暂不对第一开关组件21和第二开关组件22进行控制，充电装置直流侧的接触器吸合先行输出，电压检测器40采集到电压信号(即充电装置直流侧的输出电压极性)后，若为正，则控制器30控制第一单刀双掷开关SW1的不动端与第一动端连接，第二单刀双掷开关SW2的不动端与第二动端连接，若为负，则控制器30控制第一单刀双掷开关SW1的不动端与第二动端连接，第二单刀双掷开关SW2的不动端与第一动端连接。When the rail vehicle is parked at the charging station and the driving direction signal is not sent when the CCU fails, for example, when the controller 30 does not receive the driving direction signal within a preset time (such as 3s), the controller 30 does not temporarily switch the first switch assembly 21 Controlled with the second switch assembly 22, the contactor on the DC side of the charging device pulls in and outputs first, and the voltage detector 40 collects the voltage signal (that is, the output voltage polarity of the DC side of the charging device), and if it is positive, the controller 30 controls the fixed end of the first single-pole double-throw switch SW1 to be connected to the first moving end, and the fixed end of the second single-pole double-throw switch SW2 to be connected to the second moving end; if negative, the controller 30 controls the first single-pole The fixed end of the double throw switch SW1 is connected to the second moving end, and the fixed end of the second single pole double throw switch SW2 is connected to the first moving end.
