[0040] As briefly mentioned earlier, traditional electrical control panels require the installation of multiple circuit breakers. Installers typically need to record the device locations using pen and paper, and then configure the circuit breaker positions on the control panel after installation. This method is prone to discrepancies between the actual device installation locations and the software-defined locations when dealing with a large number of devices within the control panel, which can impact on-site control panel maintenance.

[0041] The circuit breaker positioning scheme provided by the embodiments of this disclosure solves or at least partially solves the aforementioned problems or other potential problems existing in the conventional technology. The circuit breaker positioning method provided by the embodiments of this disclosure, in response to receiving a position matching command, controls the first circuit breaker of a plurality of circuit breakers coupled to a control panel to trip; acquires at least two sound source angle information related to the tripping of the first circuit breaker, wherein the at least two sound source angle information are determined by at least two sound sensors located at different positions within the control panel based on at least two sound signals acquired during the tripping of the first circuit breaker; and determines the actual position information of the first circuit breaker based on the at least two sound source angle information.

[0042] In this way, the gateway device can sequentially control the circuit breakers installed in the control panel to disconnect, and determine the actual installation position of the circuit breaker (hereinafter referred to as actual position information) based on the sound emitted by the handle mechanism (or knob) when each circuit breaker disconnects. The gateway device of the control panel can also match the actual position information of the circuit breaker with the positions of multiple compartments in the control panel (hereinafter referred to as preset position information). In this way, the circuit breaker is associated with a given compartment in the control panel. By continuously repeating the above steps, multiple circuit breakers in the control panel can be associated with multiple compartments in the control panel, thus realizing the determination of the positions of multiple circuit breakers in the control panel. This improves the efficiency and accuracy of control panel installation and maintenance.

[0043] Figure 1 A schematic diagram of an apparatus 100 for implementing a circuit breaker positioning method according to some embodiments of the present disclosure is shown. Figure 1 As shown, the device 100 is arranged inside a control panel and includes at least two sound sensors 120 and a gateway device 110. The circuit breakers of the control panel are connected to the gateway device 110, which can assign communication addresses to multiple circuit breakers. In this way, the gateway device 110 can control a specific circuit breaker (e.g., the first circuit breaker) among multiple circuit breaker devices to perform a disconnection action.

[0044] The sound sensor 120 is adapted to acquire sound signals during the interruption of the circuit breaker in the control panel, and to determine the sound source angle information based on the sound signals using a computing chip inside the sound sensor 120. The sound source angle information is used to at least indicate the angle between the sound source location (i.e., the installation location of the first circuit breaker where the interruption occurs) and the sound sensor 120 relative to a predetermined direction (e.g., the direction of gravity).

[0045] Gateway device 110 is also connected to at least two sound sensors 120 and is adapted to acquire at least two sound source angle information related to the breaking of the first circuit breaker during the period when the first circuit breaker is controlled to break by gateway device 110. Gateway device 110 can process the acquired at least two sound source angle information to determine the actual position information of the first circuit breaker. The following description will primarily use an apparatus comprising two sound sensors as an example to illustrate the method and apparatus for locating circuit breakers. It should be understood that the same applies to the case where the apparatus comprises more than two sound sensors (e.g., three, four, etc.).

[0046] Figure 2 A schematic diagram of the internal structure of a cabinet 200 according to some embodiments of the present disclosure is shown. For example... Figure 2As shown, the control panel 200 has multiple compartments 210, each adapted to accommodate a circuit breaker 220. In some embodiments, two sound sensors 120 are respectively arranged at different locations within the control panel 200. Specifically, the two sound sensors 120 may be coupled to the same side of the control panel 200 near its edge. For example, the two sound sensors 120 may be arranged on the right side of the control panel 200 facing the user.

[0047] Figure 3 A schematic diagram illustrating the determination of the actual position information of a circuit breaker based on the angle information of two sound sources according to some embodiments of this disclosure is shown. Figure 3 As shown, if the first circuit breaker among the multiple circuit breakers 220 in the control panel 200 trips, the two sound sensors 120 in the control panel 200 acquire two sound source angle information. It should be understood that, due to the different installation positions of the two sound sensors within the control panel, the sound generated during the tripping of the first circuit breaker is transmitted to the two sound sensors, resulting in differences in intensity and timing between the two sound signals acquired by the two sensors. Therefore, the two sound sensors can determine the two sound source angle information based on their respective acquired sound signals.

[0048] Since the sound sensors 120 are arranged on the same side of the panel 200 near the edge, the gateway device 110 can determine the location of the circuit breaker that has broken within the panel 200 by using the two sound source angle information determined by the two sound sensors 120 respectively.

[0049] In some embodiments, the gateway device 110 can also determine the actual location information of the first circuit breaker based on the Time Difference of Arrival (TDOA) algorithm. The gateway device 110 determines the time delay difference between the arrival of the circuit breaker's acoustic waves at different sound sensors 120 based on the TDOA algorithm, calculates the distance difference using the time delay, and then uses the distance difference and the spatial geometric position of the sound sensors 120 to determine the location of the sound source. This can be divided into TDOA estimation (estimating the time difference of signal arrival at each microphone) and TDOA localization (using geometric relationships to determine the location of the sound source).

[0050] Figure 4 A flowchart of a process 400 for determining the location of a circuit breaker according to some embodiments of the present disclosure is shown. Figure 4As shown, in box 410, maintenance personnel install multiple circuit breakers and related electrical equipment (e.g., drawers) into multiple slots within the control panel, and connect the circuit breakers to gateway device 110 respectively. In box 420, gateway device 110 assigns communication addresses to each of the circuit breakers. It should be understood that gateway device 110 can assign addresses to circuit breakers as each circuit breaker is connected to gateway device 110. Gateway device 110 can also assign addresses to all circuit breakers uniformly after all circuit breakers are installed. In box 430, maintenance personnel can also import the control panel topology information into the gateway.

[0051] In some embodiments, the topology information includes the distribution of compartments in the cabinet where circuit breakers can be installed. Maintenance personnel can input topology information into the gateway device 110 by sending text, images, videos, etc., and the gateway device 110 determines the preset location information of multiple compartments within the cabinet based on the topology information. For example, maintenance personnel can take a photo showing the internal structure of the current cabinet and input the photo into the gateway device 110. The gateway device 110 can analyze the photo based on a data model to confirm the distribution of compartments inside the cabinet in the photo (i.e., the preset location information of multiple compartments). In some other embodiments, users can also manually input the topology information of the cabinet into the gateway device 110.

[0052] return Figure 4 In box 440, maintenance personnel switch all circuit breakers in the control panel to the closed state. In box 450, maintenance personnel send a location matching command to gateway device 110, which then detects the location of each circuit breaker. For example, gateway device 110 can disconnect circuit breakers one by one based on a pre-determined communication address and determine the actual location information of the currently disconnected circuit breaker based on the sound of the circuit breaker disconnecting. The actual location information reflects the actual installation position of the circuit breaker within the control panel. In some other embodiments, gateway device 110 can also match the actual location information of the circuit breaker with the preset location information of the compartments in the control panel, thereby associating the circuit breaker with the compartments of the control panel. This method completes the detection of the circuit breaker's location.

[0053] Gateway device 110 repeats the above detection steps and detects the location of all circuit breakers installed in the cabinet. In frame 460, gateway device 110 forms a device distribution interface based on topology information and the association between circuit breakers and their slots. The device distribution interface of the cabinet can reflect the specific slot location of each circuit breaker in the cabinet, and can prompt maintenance personnel by flashing, highlighting, or other methods when gateway device 110 operates a certain circuit breaker.

[0054] Figure 5A schematic block diagram of a circuit breaker location method 500 according to some embodiments of the present disclosure is shown. Method 500 can be performed by a gateway device 110 in apparatus 100.

[0055] like Figure 5 As shown in block 510, in response to receiving a location matching command, gateway device 110 controls the first circuit breaker of a plurality of circuit breakers coupled to the control panel to trip. In some embodiments, maintenance personnel can send a location matching command to gateway device 110. After receiving the location matching command, gateway device 110 can control the plurality of circuit breakers in the control panel to perform tripping operations sequentially. Gateway device 110 can control the circuit breakers to trip sequentially at predetermined time intervals. For example, gateway device 110 can control the first circuit breaker of the plurality of circuit breakers to trip, and control the second circuit breaker of the plurality of circuit breakers to trip 10 seconds after the first circuit breaker trips.

[0056] In some embodiments, before controlling the first circuit breaker to trip, the gateway device 110 may assign communication addresses to multiple circuit breakers connected to the gateway device 110. During the sequential tripping of multiple circuit breakers, the gateway device 110 may control the circuit breakers to trip in the order of the assigned communication addresses.

[0057] In box 520, gateway device 110 acquires at least two sound source angle information related to the breaking of the first circuit breaker. The at least two sound source angle information are determined by at least two sound sensors 120 located at different positions in the control panel based on sound signals acquired during the breaking of the first circuit breaker.

[0058] In some embodiments, the sound signal includes at least intensity information of the sound wave associated with the circuit breaker tripping and time information of the time when the sound wave is detected. The sound sensor 120 can determine the angle between the sound source location (the actual installation location of the first circuit breaker) and the sound sensor 120 relative to a predetermined direction based on the sound signal. After determining the sound source angle information based on the sound signal, the sound sensor can send the sound source angle information to the gateway device 110.

[0059] In block 530, gateway device 110 determines the actual location information of the first circuit breaker based on at least two sound source angle information. For example, gateway device 110 may combine the predefined positions of at least two sound sensors in the gateway device and solve for the intersection of at least two rays representing at least two sound source angle information to determine the actual location information of the first circuit breaker.

[0060] In some embodiments, the gateway device 110 may also determine the distance difference between the first circuit breaker and at least two sound sensors 120 based on the time delay difference of at least two sound signals, and determine the actual location information of the first circuit breaker based on the distance difference and the installation positions of at least two sound sensors 120.

[0061] In some embodiments, the gateway device 110 may also acquire topology information about the installation locations of circuit breakers in the control panel. Based on the topology information, the gateway device 110 determines multiple preset location information for multiple slots where multiple circuit breakers can be installed. In response to a match between the actual location information of a first circuit breaker and the preset location information of a given slot among the multiple slots, the gateway device 110 associates the first circuit breaker with the given slot. In some embodiments, the topology information may include at least one of text information, image information, and video information.

[0062] For example, maintenance personnel can input the topology information of the control panel into the gateway device 110 before issuing a location matching command. The maintenance personnel can input the information manually or send photos of the inside of the control panel to the gateway device 110. Based on the topology information input by the maintenance personnel, the control panel can determine the preset location information of multiple slots within the control panel for installing multiple circuit breakers. In this way, maintenance personnel can choose the appropriate method to input the topology information of the control panel into the gateway device according to the current work scenario, thereby improving the efficiency of control panel installation and configuration.

[0063] In some embodiments, the preset position information for each grid cell can be a range. For example, the preset position information for a given grid cell can be represented by a pair of coordinates (x1, y1) and (x2, y2) located diagonally opposite the grid cell.

[0064] After obtaining the actual location information of the first circuit breaker, the gateway device 110 can compare the obtained actual location information of the first circuit breaker with the preset location information of multiple grids to determine the given grid that matches the first circuit breaker. For example, if the determined actual location information of the first circuit breaker includes coordinates (x0, y0), and the coordinates (x0, y0) of the first circuit breaker are within the range defined by a pair of coordinates (x1, y1) and (x2, y2) of the given grid, then the first circuit breaker can be associated with the given grid. In some embodiments, the matched actual location information and the preset location information have a unique mapping relationship. In this way, the association between the first circuit breaker and the given grid is unique to each other; that is, a first circuit breaker is associated with a given grid, and the given grid is only associated with the first circuit breaker located therein. Through the association between the first circuit breaker and the given grid, maintenance personnel can more quickly and conveniently locate the required circuit breaker, improving the efficiency of internal maintenance and configuration of the control panel.

[0065] In some embodiments, the gateway device 110 issues a warning signal in response to a mismatch between the actual location information of the first circuit breaker and multiple preset location information of multiple grids. For example, if the gateway device 110 cannot find a grid that uniquely corresponds to the first circuit breaker from among the multiple grids, the gateway device 110 can send a warning signal indicating the location of the fault to the maintenance personnel so that the maintenance personnel can conduct timely inspections.

[0066] In some embodiments, the gateway device 110 can also determine the device distribution interface based on multiple preset location information of multiple slots in the cabinet. The device distribution interface can display the multiple slots of the cabinet and their locations in a graphical form. Maintenance personnel can determine whether the multiple slots and their locations determined by the gateway device 110 are correct based on the device distribution interface.

[0067] In some embodiments, associating a first circuit breaker with a given grid cell includes: the gateway device 110 determining the communication address of the first circuit breaker. The gateway device 110 associates the communication address of the first circuit breaker with preset location information of the given grid cell.

[0068] As mentioned above, gateway device 110 can determine the device distribution interface based on the preset location information of multiple grids. Gateway device 110 can also update the device distribution interface based on the association between the first circuit breaker and a given grid. Specifically, if gateway device 110 associates the first device with a given grid, it can highlight the associated first circuit breaker at the corresponding grid on the device distribution interface. For example, the device distribution interface can use highlighting, flashing, or other methods to indicate that the first circuit breaker has been associated at the corresponding grid location. In this way, maintenance personnel can more intuitively view the association between circuit breakers and grids within the control panel, and thus more quickly determine the location of relevant circuit breakers during subsequent maintenance or configuration of the control panel.

[0069] In some embodiments, the gateway device 110 can also send the association information between the first circuit breaker and a given compartment to a remote device. For example, the gateway device 110 can send the association information between the first circuit breaker and a given compartment to a remote server so as to remotely view and back up the installation information of the circuit breaker in the cabinet.

[0070] Return to reference Figure 1 In some embodiments, the gateway device 110 is configured to, in response to receiving a location matching command, control the first circuit breaker of a plurality of circuit breakers coupled to the control panel to trip; acquire at least two sound source angle information related to the tripping of the first circuit breaker, the at least two sound source angle information being determined by at least two sound sensors 120 located at different positions within the control panel based on sound signals acquired during the tripping of the first circuit breaker; and determine the actual location information of the first circuit breaker based on the at least two sound source angle information.

[0071] In some embodiments, the gateway device 110 is further configured to: acquire topology information of the cabinet regarding the installable location of the circuit breaker; determine multiple preset location information of multiple slots for installing the circuit breaker based on the topology information; and associate the first circuit breaker with the given slot in response to a match between the actual location information of the first circuit breaker and the preset location information of a given slot among the multiple slots.

[0074] In some embodiments, associating a first circuit breaker with a given grid cell includes: determining the communication address of the first circuit breaker; and associating the communication address of the first circuit breaker with preset location information of the given grid cell.

[0075] In some embodiments, topology information includes at least one of the following: text information, icon information, and video information.

[0076] In some embodiments, the gateway device 110 is further configured to issue a warning signal in response to a mismatch between the actual location information of the first circuit breaker and multiple preset location information of multiple grids.
