Within a split-type charger power distribution unit, there are multiple bus tie contactors; the more output branches, the more bus tie contactors are required. The more bus tie contactors there are, the greater the probability of installation errors, and the greater the risk of batteries from different charging circuits coming into contact due to incorrect closure of the bus tie contactors. Summary of the Invention

[0003] This invention provides a bus tie status monitoring system and method. The system monitors the working status of the bus tie contactor through the digital input terminals of the status monitoring unit, and analyzes the working status information, control information and feedback information to obtain the monitoring results of the bus tie contactor's location installation and line installation, which helps to improve the efficiency and accuracy of the detection.

[0022] If the working status information and the control information indicate inconsistent bus tie contactor status, but the control information and the feedback information indicate consistent bus tie contactor status, then the installation monitoring result is determined to be that the control line is installed incorrectly and the feedback line is installed correctly.

[0023] If the working status information and the control information indicate inconsistent bus tie contactor status, and the control information and the feedback information indicate inconsistent bus tie contactor status, then the installation monitoring results are determined to be incorrect control line installation and incorrect feedback line installation.

[0024] In one possible example, determining the action monitoring result of the bus tie contactor based on the operating status information and the control information includes:

[0043] To facilitate understanding of the technical solution of this application, the relevant technologies involved in this application will be introduced first.

[0044] See Figures 1-5 , Figure 1 This is an architecture diagram of a bus coupler status monitoring system provided in an embodiment of this application; Figure 2 This is a schematic diagram illustrating the connection between a status monitoring unit and a bus tie contactor provided in an embodiment of this application. Figure 3 This is a connection diagram of a status monitoring unit, a charging control unit, and a bus tie contactor provided in an embodiment of this application; Figure 4 This is a connection diagram of another state monitoring unit, charging control unit, and bus tie contactor provided in an embodiment of this application; Figure 5 This is a schematic diagram of a power output power and bus tie contactor provided in an embodiment of this application.

[0045] The bus tie status monitoring system 1 includes a status monitoring unit 10, a charging control unit 20, and a data processing unit 30, with the data processing unit 30 located inside the status monitoring unit 10. The status monitoring unit 10 is connected to the bus tie contactor and is used to collect the operating status information of the bus tie contactor, which connects any two power output circuits of the charging pile. The charging control unit 20 is connected to the bus tie contactor and transmits control information to and receives feedback information from the bus tie contactor. The data processing unit 30 is connected to both the status monitoring unit 10 and the charging control unit 20. The data processing unit 30 receives the operating status information from the status monitoring unit 10, and receives the control information and feedback information from the charging control unit 20. Based on the operating status information, the control information, and the feedback information, it determines the installation monitoring result of the bus tie contactor. When the installation monitoring result indicates an incorrect installation of the bus tie contactor or an incorrect wiring installation, the data processing unit generates an alarm message and transmits the alarm message and the operating status information to the charging control unit.

[0046] The status monitoring unit 10 includes a first digital input terminal and a second digital input terminal. The first digital input terminal is connected to the positive terminal of the power output circuit of the charging pile, and the second digital input terminal is connected to the negative terminal of the power output circuit of the charging pile. The status monitoring unit 10 is used to record the conduction status information of the digital input terminals and uses the conduction status information as the working status information of the bus tie contactor.

[0047] The control information is used to control the closing / opening of the bus tie contactor. The operating status information reflects the actual closing / opening status of the current bus tie contactor, and the feedback information is the closing / opening status reported by the bus tie contactor itself.

[0048] For an example, please refer to Figure 2 The charging pile includes three power output circuits: DC1, DC2, and DC3. Bus tie contactor K1 connects to two power output circuits, DC1 and DC2, and bus tie contactor K2 connects to two power output circuits, DC2 and DC3. The digital input terminals of the status monitoring unit 10 include DI1, DI2, and DI3. DI1 is connected to DC1, DI2 to DC2, and DI3 to DC3. The status monitoring unit 10 records the conduction status of the digital input terminals. The conduction status of the digital input terminals is the same as the conduction status of the three power output circuits (DC1, DC2, and DC3), which reflects the operating status of the bus tie contactors. For example, when K1 is closed, power output circuits DC1 and DC2 are connected, and DI1 and DI2 are also connected.

[0049] The number of power output circuits in the power distribution unit of the charging pile is not limited. For example, it can be 9, 12, 18, 24, etc. As the number of power output circuits increases, the number of bus tie contactors also increases, and the corresponding status monitoring unit 10 also increases.

[0050] In one possible example, there are multiple bus tie contactors, and the charging control unit is connected to multiple bus tie contactors respectively. The charging control unit is used to control the closing and opening of multiple bus tie contactors sequentially through the control information.

[0051] There are multiple condition monitoring units 10, each capable of monitoring one or more bus tie contactors. Each condition monitoring unit has a unique identification number. Please refer to [link / reference]. Figure 4 The diagram illustrates multiple bus tie contactors numbered 1-n, m status monitoring units 10, a data processing unit 30, and a charging control unit 20. Each status monitoring unit 10 can be connected to the positive and negative terminals of the bus tie contactor. The status monitoring unit acquires the status signals (operating status information) of the bus tie contactor, reflecting its actual state (closed / open). The charging control unit transmits control signals (control information) to the bus tie contactor and receives feedback signals (feedback information) from the bus tie contactor. The charging control unit 20 transmits the current control command (the current control signal transmitted to the bus tie contactor) and the current feedback status (the feedback signal from the current bus tie contactor) to the data processing unit 30. The data processing unit 30 analyzes the operating status information, feedback information, and control information to derive the installation monitoring results. If the installation monitoring results indicate an installation error in the bus tie contactor, the data processing unit 30 transmits the operating status information and error alarm information to the charging control unit 20.

[0052] The status monitoring unit 10 and the charging control unit 20 are connected via an RS-485 bus (A line and B line).

[0053] The charging control unit can sequentially control the closing and opening of multiple bus tie contactors through multiple control signals. For example, it can sequentially control the closing and opening of bus tie contactors K1-K22 at 5-second time intervals to ensure that only one bus tie contactor is in the closed state at any given time.

[0054] Please see Figure 3 The charging control unit 20 includes an output signal channel D0 and an input signal channel DI. The bus tie contactor includes a control signal port and a feedback signal port. The output signal channel D0 is connected to the control signal port of the bus tie contactor, and the input signal channel DI is connected to the feedback signal port.

[0055] Each bus tie contactor is connected to the charging control unit 20.

[0056] Among them, the control line refers to the line between the output signal channel D0 and the control signal port, and the feedback line refers to the line between the input signal channel DI and the feedback signal port.

[0057] In one possible example, the bus status monitoring system 1 includes an auxiliary power supply, which is connected to the status monitoring unit 10, the charging control unit 20 and the data processing unit 30 respectively. The auxiliary power supply is used to power the status monitoring unit 10, the charging control unit 20 and the data processing unit 30.

[0058] Both the status monitoring unit 10 and the charging control unit 20 include 12V+, 12V- and GND pins for connecting to the auxiliary power supply.

[0059] The auxiliary power supply output voltage can be 12V.

[0060] For an example, please refer to Figure 5 The charging pile includes power output circuits DC1-DC12. The positive terminals of output circuits DC1-DC12 are connected to the first digital input terminals DI1-DI12 of the status monitoring unit, and the negative terminals of output circuits DC1-DC12 are connected to the second digital input terminals DI13-DI24 of the status monitoring unit. The bus tie contactor parameters are as follows: the bus tie contactor between the first power output circuit DC1 and the second power output circuit DC2 is K1; the bus tie contactor between the second power output circuit DC2 and the third power output circuit DC3 is K2; and so on, the bus tie contactor between the third power output circuit DC3 and the twelfth power output circuit DC12 is K22. That is, each bus tie connects two output circuits respectively.

[0061] Please see Figure 6 , Figure 6 This is a flowchart of a bus coupler status monitoring method provided in an embodiment of this application. The bus coupler status monitoring method is described as follows: A data processing unit applied to the bus coupler status monitoring system includes:

[0062] Step S601: Obtain the working status information from the status monitoring unit.

[0063] Step S602: Obtain control information and feedback information from the charging control unit.

[0064] Step S603: If it is determined that the working stage of the bus tie status monitoring system is the inspection stage, then the installation monitoring result of the bus tie contactor is determined based on the working status information, the control information and the feedback information.

[0065] The working phase of the bus tie status monitoring system is the inspection phase, which indicates that it is uncertain whether the bus tie contactor is installed correctly and requires analysis and confirmation.

[0066] Step S604: If it is determined that the working stage of the bus tie status monitoring system is the operation stage, then the action monitoring result of the bus tie contactor is determined based on the working status information and the control information.

[0067] The working phase of the bus tie status monitoring system is the operation phase, which indicates that the bus tie contactor is installed correctly and no further analysis or confirmation is needed.

[0068] In one possible example, determining the installation monitoring result of the bus tie contactor based on the operating status information, the control information, and the feedback information includes the following steps: If the bus tie contactor status indicated by the operating status information and the control information is consistent, and the bus tie contactor status indicated by the control information and the feedback information is also consistent, then the installation monitoring result is determined to be that the bus tie contactor is installed correctly, the control line is installed correctly, and the feedback line is installed correctly; if the bus tie contactor status indicated by the operating status information and the control information is consistent, and the bus tie contactor status indicated by the control information and the feedback information is inconsistent, then the installation monitoring result is determined to be that the bus tie contactor is installed correctly, the control line is installed correctly, and the feedback line is installed correctly. If the installation monitoring results are inconsistent, the bus tie contactor is correctly installed, the control line is correctly installed, and the feedback line is incorrectly installed. If the working status information and the control information indicate inconsistent bus tie contactor status, but the control information and the feedback information indicate consistent bus tie contactor status, then the installation monitoring results are incorrect control line installation and correct feedback line installation.

[0069] For example, if the operating status information, control information, and feedback information all indicate that the bus tie contactor is closed / open, it means that the bus tie contactor is installed correctly (i.e., correctly installed between the corresponding two power outputs), and the control line and feedback line are also installed correctly. If the bus tie contactor status indicated by the operating status information is the same as that indicated by the control information, but the bus tie contactor status indicated by the feedback information is different from that indicated by the control information, then it is determined that the bus tie contactor is installed correctly, the control line is installed correctly, but the feedback line is installed incorrectly. That is, the wiring between the input signal channel DI and the feedback signal port is incorrectly installed. The data processing unit sends an alarm signal and operating status information to the charging control unit. You can check which bus tie contactor is currently closed and adjust it to the correct position. If the bus tie contactor status indicated by the operating status information differs from that indicated by the control information, but the bus tie contactor status indicated by the feedback information matches that indicated by the control information, then the bus tie contactor is correctly installed, but the control line is incorrectly installed (i.e., the wiring between the output signal channel D0 and the control signal port is incorrect). The feedback line is correctly installed. The data processing unit sends an alarm signal and operating status information to the charging control unit. Check which bus tie contactor is actually sampling closed and adjust it to the correct position. If the bus tie contactor status indicated by the operating status information differs from that indicated by the control information, and the bus tie contactor status indicated by the feedback information also differs from that indicated by the control information, then both the feedback line and the control line are incorrectly installed. The data processing unit sends an alarm signal and operating status information to the charging control unit. Check which bus tie contactor is actually sampling and feedback closed and adjust it to the correct position.

[0070] In one possible example, determining the action monitoring result of the bus tie contactor based on the operating status information and the control information includes the following steps: if the operating status information and the control information indicate the same bus tie contactor status, then the action monitoring result is determined to be no failure to operate and no erroneous operation; if the operating status information indicates the bus tie contactor status is closed and the control information indicates the bus tie contactor status is open, then the action monitoring result is determined to be a erroneous operation of the bus tie contactor; if the operating status information indicates the bus tie contactor status is open and the control information indicates the bus tie contactor status is closed, then the action monitoring result is determined to be a failure to operate of the bus tie contactor.

[0071] Among them, maloperation refers to the discrepancy between the actual action of the bus tie contactor and the action it performs as instructed by the control signal, while failure to operate refers to the bus tie contactor not performing an action after receiving a control signal.

[0072] As can be seen in this example, the data processing unit can obtain the working status information of the status monitoring unit, as well as the control information and feedback information of the charging control unit. According to the working stage of the bus tie status monitoring system, it can select and analyze the working status information, control information and feedback information accordingly to obtain the installation monitoring results or action monitoring results of the bus tie contactor, which is conducive to improving the monitoring efficiency and accuracy of the bus tie contactor.

[0073] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application, which is a data processing unit applied in a bus coupler status monitoring system; such as Figure 7 As shown, the electronic device includes a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory, and the one or more programs are configured to be executed by the processor according to the following instructions:

[0074] Obtain operational status information from the status monitoring unit;

[0075] Obtain control information and feedback information from the charging control unit;

[0076] If the working stage of the bus tie status monitoring system is determined to be the inspection stage, the installation monitoring result of the bus tie contactor is determined based on the working status information, the control information, and the feedback information.

[0077] If the working stage of the bus tie status monitoring system is determined to be the operation stage, then the action monitoring result of the bus tie contactor is determined based on the working status information and the control information.

[0078] As can be seen, in this example, the electronic device can obtain the working status information of the status monitoring unit, as well as the control information and feedback information of the charging control unit. According to the working stage of the bus tie status monitoring system, the electronic device can select and analyze the working status information, control information and feedback information accordingly to obtain the installation monitoring results or action monitoring results of the bus tie contactor, which is beneficial to improving the monitoring efficiency and accuracy of the bus tie contactor.

[0079] In one possible example, determining the installation monitoring result of the bus tie contactor based on the operating status information, the control information, and the feedback information includes the following steps: If the bus tie contactor status indicated by the operating status information and the control information is consistent, and the bus tie contactor status indicated by the control information and the feedback information is also consistent, then the installation monitoring result is determined to be that the bus tie contactor is installed correctly, the control line is installed correctly, and the feedback line is installed correctly; if the bus tie contactor status indicated by the operating status information and the control information is consistent, and the bus tie contactor status indicated by the control information and the feedback information is inconsistent, then the installation monitoring result is determined to be that the bus tie contactor is installed correctly, the control line is installed correctly, and the feedback line is installed correctly. If the installation monitoring results are inconsistent, the bus tie contactor is correctly installed, the control line is correctly installed, and the feedback line is incorrectly installed. If the working status information and the control information indicate inconsistent bus tie contactor status, but the control information and the feedback information indicate consistent bus tie contactor status, then the installation monitoring results are incorrect control line installation and correct feedback line installation.

[0080] In one possible example, determining the action monitoring result of the bus tie contactor based on the operating status information and the control information includes the following steps: if the operating status information and the control information indicate the same bus tie contactor status, then the action monitoring result is determined to be no failure to operate and no erroneous operation; if the operating status information indicates the bus tie contactor status is closed and the control information indicates the bus tie contactor status is open, then the action monitoring result is determined to be a erroneous operation of the bus tie contactor; if the operating status information indicates the bus tie contactor status is open and the control information indicates the bus tie contactor status is closed, then the action monitoring result is determined to be a failure to operate of the bus tie contactor.
