With the increasing number of power users, it is very important to use topology information reasonably to deal with intelligent power management. Therefore, the need to quickly obtain the topology information of the terminal equipment in the distribution network and the meter box is also increasingly urgent. However, the number of users in the low-voltage station area is large, the lines in the station area are complex, and there are many branch lines in the distribution and transformation station area. The acquisition of the topology structure between the components in the power grid meter box, such as the electricity meter and the switch before and after the meter, has always been Problems in electricity service.

At present, the common methods for identifying the topological relationship of components in the power grid meter box are: 1) Using the power carrier communication technology, this method has the influence of the transmission dead zone and the load of the distribution station area, channel interference and noise factors, and the length of the line has an impact on the communication channel. The longer the line, the greater the attenuation of the signal, which makes the identification accuracy and efficiency of the topology relationship relatively low; 2) Inject the power frequency signal into the distribution line, and use the acquisition device to detect the injected signal. This method involves Power consumption and safety issues; 3) Relying on the meter reading file of the centralized reading system to manage the meter in the station area, and recording the topology structure of the station area by the maintenance personnel in the low-voltage station area by opening the gate and manually drawing, this method is inefficient. , the accuracy is not high.

It can be seen that the existing technology for identifying topological relationships of components in a power grid meter box still has technical problems such as low identification accuracy, low identification efficiency, high power consumption, and poor security.

Thus, the present invention is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features disclosed in the embodiments of this application.

Embodiments of the present application provide a method, device, device, and storage medium for topology identification of meter box components, which will be described in detail below.

Firstly, the background of the realization of the present invention is briefly explained. With the increasing number of power users, the relationship between the components in the meter box is often chaotic, mainly the connection relationship between the front switch, the meter and the rear switch, and considering There is a serious problem of wire winding in the meter box, and most of the wires are located in the invisible area, which makes it impossible to simply identify the connection relationship of each element in the meter box based on the connection of the wires. Therefore, various auxiliary technical means are often required for identification, such as The common power carrier communication technology uses the means of injecting power frequency signals, and the above-mentioned technical means have more or less problems in terms of identification accuracy, identification efficiency and security. Based on this, the present invention proposes a method for identifying topology of meter box components, which is mainly used to realize the identification of the topology relationship among the switches in front of the meter, the electricity meter and the switches behind the meter in the meter box.

The meter box element topology identification method in the embodiment of the present invention is applied to the meter box element topology identification device, the meter box element topology identification device is set in the meter box element topology identification device, and the meter box element topology identification device is provided with one or more processing a processor, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the meter box element topology identification method; the meter box element topology identification device may be a terminal For example, a mobile phone or a tablet computer, the device for identifying the topology of the table box element can also be a server, or a service cluster composed of multiple servers.

As shown in FIG. 1, FIG. 1 is a schematic diagram of a scene of topology identification of meter box components according to an embodiment of the present application, and can also be understood as a structural diagram of each element in a meter box. Mainly includes the front switch 100, the electricity meter 200, the back switch 300 and the meter box element topology identification device 400 (the meter box element topology identification device 400 is integrated with a meter box element topology identification device), and the meter box element topology identification device 400 runs in The meter box element topology identification corresponds to the storage medium to perform the step of meter box element topology identification, that is, the meter box element topology identification method proposed by the present invention mainly runs independently on the meter box element topology identification device 400 .

Those skilled in the art know that in a meter box, a front-meter switch, an electricity meter, and a rear-meter switch need to be set in sequence on the circuit entering the household, that is, there is a circuit between the front-meter switch, the electricity meter, and the rear-meter switch on a line. topologically. In a meter box for multiple households, there are often multiple front-meter switches 100 , electricity meters 200 and rear-meter switches 300 having a topology relationship. However, in order to simplify the description, the present invention only takes a meter box composed of two front-meter switches 100, two electricity meters 200 and two rear-meter switches 300 as an example for description. , the meter box composed of the electricity meter 200 and the switch 300 behind the meter, the topology identification method of the meter box components adopted is essentially the same, which can be deduced by analogy.

The topology identification method of meter box components proposed by the present invention is mainly used to identify the topology relationship between the front switch and the meter and the topology relationship between the meter and the switch behind the meter. In other words, the front switch, the meter and the switch behind the meter can be identified. One-to-one topological relationship between the three.

In order to realize the present invention, it is usually necessary to improve the switch and the electric meter so that they have specific functions. For example, a wireless communication module needs to be added to the switch and the electric meter, so that it can search for nearby components or be detected by wireless communication on other components. module found. Or it is necessary to improve the meter and add a circuit switch inside it, so that it has the function of controlling the on-off of the circuit in the rear section, and for the switch in front of the meter, because it can be understood as a circuit that controls the on-off of the circuit in the rear section. circuit switch, so there is no need to add a circuit switch. In addition, it should be noted that there are electric meters and switches with corresponding functions in the prior art, so the above improvement is obviously achievable, and the invention of the present invention is not in the process of improving the electric meter. The above improved process is not described in detail.

Because the topology identification method of the meter box element proposed by the present invention can realize the identification of the topology relationship between the front switch and the meter, and can realize the identification of the meter and the switch behind the meter, therefore, the first element and the second element are used to refer to the identification subject respectively. And the recognized object, usually, the first element is the front switch or the meter, and the second element is the meter or the switch behind the meter, that is, when the first element, that is, the identification subject, is the front switch, the second element is the switch in front of the meter. The component, that is, the recognized object is usually an electric meter, and of course it may be a switch behind the meter. When the first element, that is, the identified subject is an electric meter, the second component is usually only a switch behind the meter, which is also related to the circuit. The connection relationship of each element in the household is related to the order, that is, the elements arranged on the front-end circuit can control the on-off of the latter-stage circuit through the circuit switch, so the identification subject often needs to be located in the front of the circuit, and the recognized object needs to be located in the back of the circuit. , to be controlled by the circuit switch of the identification body in the preceding paragraph.

In order to realize the identification and search of the component identity, each component will be associated with a wireless communication module. Usually, this association refers to setting a wireless communication module on the component. When a component is powered on, it will be connected to it. The associated wireless communication module will start to work, it can search for other wireless communication modules, and can also be searched by other wireless communication modules, and when it is powered off, the associated wireless communication module will stop working, that is, it cannot be Searched by the wireless communication module. It should be noted that when a wireless communication module and a circuit switch are installed on the component at the same time, the circuit switch needs to be arranged downstream of the wireless communication module, that is, the rear section. In this way, the circuit switch will only affect the rear section of the circuit, and It will not affect the work of its own wireless communication module. Taking the front switch as an example, the wireless communication module associated with the front switch needs to be installed in the front section of the front switch. Specifically, it can be powered by the voltage of the incoming line. At this time, the on-off of the front switch will not affect the switch. The operation of the wireless communication module associated with the switch in front of the meter will only affect the on-off of the circuit in the rear section, that is, it will affect the operation of the wireless communication module on the electric meter and the switch behind the meter.

In the embodiment of the present invention, the meter box element topology identification device 400 can be understood as an independent functional module, which can exchange information with meter box elements in some feasible ways, such as acquiring the search results of the wireless communication module on the element. The set of identification information and the state information of circuit switches. Specifically, after the element searches for the identification information set based on the wireless communication module, it will send the identification information set to the meter box element topology identification device 400, and will also send the state of the circuit switch associated with itself to the meter box element topology identification device 400. information. Or when a certain first element is predetermined and the association of the first element needs to be identified, the table box element topology identification device 400 can search for the identification information set through the wireless communication module set by itself, then the identification information A set may also be considered to be associated with the aforementioned predetermined first element. In addition, the meter box element topology identification device 400 can also determine the state of the circuit switch by detecting the position information of the gear position of the circuit switch. At this time, for details of the method for identifying the topology of the meter box element performed on the meter box element topology identification device 400, reference may be made to the content of the subsequent FIG. 2 and its explanation.

As another feasible solution, the meter box element topology identification device 400 does not exist independently, but is integrated in the identification body that can actively identify the association relationship, that is, the switch in front of the meter or the electricity meter. At this time, the switch or electricity meter in front of the meter will be used as the main body of the topology identification method of meter box components, and based on the topology identification method of meter box components, the relationship identification of the recognized object can be realized. At this time, with the switch in front of the meter or the electricity meter as the main body, the specific method of identifying the topology of the meter box components can refer to the following FIG. 9 and the content of its explanation.

In the embodiment of the present invention, the device 400 for identifying the topology of the meter box element is mainly used to: acquire the identification information set searched by the wireless communication module associated with the first element and the state of the circuit switch associated with the first element; if the identification information set In the identification information update or the state switching of the circuit switch, then determine the associated identification information associated with the state switching according to the update information of the identification information in the identification information set and the state switching information of the circuit switch; A second element corresponding to the association identification information is determined, and an association relationship is determined between the first element and the second element.

It can be understood that the meter box element topology identification device in the meter box element topology identification scenario shown in FIG. 1 , or the device included in the meter box element topology identification device does not constitute a limitation to the embodiment of the present invention, that is, the meter box The number and types of devices included in the scene identified by the component topology, or the number and types of devices included in each device do not affect the overall implementation of the technical solutions in the embodiments of the present invention, and can be regarded as the technical solutions claimed in the embodiments of the present invention. Equivalent replacement or derivation.

It should be noted that the schematic diagram of the scene of topology identification of meter box components shown in FIG. 1 is only an example, and the scene of topology identification of meter box components described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention. It does not constitute a limitation to the technical solutions provided by the embodiments of the present invention.

Based on the above scenario of meter box element topology identification, an embodiment of a meter box element topology identification method is proposed.

As shown in FIG. 2 , FIG. 2 is a schematic flowchart of a method for identifying the topology of a meter box element proposed by an embodiment of the application. In this embodiment, the method for identifying the topology of a meter box element mainly operates on the meter box element topology shown in the aforementioned FIG. 1 . On the identification device 400, it specifically includes steps 201-202:

201. Acquire a set of identification information searched by a wireless communication module associated with the first element and a state of a circuit switch associated with the first element.

The meter box element topology identification method in this embodiment is applied to the meter box element topology identification device. The type of meter box element topology identification device is not specifically limited. For example, the meter box element topology identification device may be a terminal or a server. The terminal is implemented in the manner of a terminal, so this embodiment takes a terminal as an example for description.

In this embodiment, the identification information set usually includes at least one identification information, and of course it may be an empty set, that is, there is no identification information. In the present invention, the identification information can be understood as the identification information of each element in the table box system, that is, for any identification information, the element corresponding to the identification information can be identified.

In this embodiment, it can be known from the foregoing that there are various implementations for acquiring the identification information set searched by the wireless communication module associated with the first element. For example, it can be sent by the first element itself after the identification information set is searched through the wireless communication module, or it can be pre-designated to identify a certain first element, and actively search for the identification information set through its own wireless communication module, Then the searched identification information set can be considered as being associated with the first element. Of course, there are other feasible solutions, and the present invention does not limit the specific acquisition method. Any acquired identification information set associated with the first element should be regarded as within the scope of protection of the present invention.

In this embodiment, the state of the circuit switch associated with the first element can also be realized in various ways, for example, in an active way, that is, the first element actively sends the state of its own circuit switch, or adopts a passive way That is, the state of the first element circuit switch is determined by judging the position information of the switch position of the first element circuit switch or by judging the circulation of the circuit current in the back stage of the first element circuit switch. Similarly, the present invention does not limit the specific method of obtaining the state of the circuit switch, and any method that can obtain the state of the circuit switch of the first element should be regarded as within the scope of protection of the present invention.

In this embodiment, considering the cost and actual working conditions, the wireless communication module usually refers to a low-power and short-range communication functional module, such as Bluetooth, Wifi, LoRa, etc., and in order to ensure the wireless communication associated with the first element The communication module can search for the identification information of other devices. Usually, the corresponding wireless communication module should be set on other components on the watch box.

In this embodiment, in order to simplify the description, the wireless communication module associated with the first element in the follow-up directly adopts the wireless communication module of the first element, and the circuit switches associated with the first element directly adopt the wireless communication module of the first element. The description of the circuit switch, wherein the circuit switch of the first element is not the circuit switch that controls the first element, but refers to the circuit switch arranged in the first element to control the on-off of the circuit in the later stage.

It should be noted that, in this embodiment, the identification information set and the circuit switch state are obtained continuously, or in other words, they are continuously obtained in the process of running, that is, executing the method for identifying the topology of the table box components, and in the follow-up. The topology identification of the meter box components is performed by using the continuously acquired identification information set and the change of the circuit switch state.

202. If the set of identification information is updated or the state of the circuit switch is switched, then according to the updated identification information in the set of identification information and the state switching information of the circuit switch, identify that there is a topology with the first element. The second element of the relationship.

In this embodiment, under normal circumstances, it is possible to identify a second element that has a topological relationship with the first element. That is to say, based on the updated identification information in the identification information set and the state switching information of the circuit switch, it is possible to fail to identify the second element that has a topological relationship with the first element. If there is a second element with a topological relationship, it means that there is no topological relationship between the element corresponding to the updated identification information in the identification information set and the first element, which can also be regarded as a topology of the table box in essence. identification of relationships. Considering that the purpose of the present invention is to identify the topological relationship of each element in the meter box, and at the same time to simplify the description, the embodiment of the present invention is only described for the situation that the topological relationship exists between the various elements, that is, The description can be made on the situation of identifying the second element that has a topological relationship with the first element according to the updated identification information in the identification information set and the state switching information of the circuit switch.

In this embodiment, it can be understood that under normal circumstances, when the circuit switch provided on the first element is placed in an off state, that is, the back-end circuit is in an open-circuit state, the second element on the back-end circuit and its set wireless communication If the module is not powered on, the wireless communication module of the first element cannot search for the identification information corresponding to the wireless communication module set on the second element. On the contrary, when the circuit switch set on the first element is placed in the closed state, that is, The back-end circuit is in an open state, the second element on the back-end circuit and its wireless communication module are powered on, and the wireless communication module of the first element can search for identification information corresponding to the wireless communication module set on the second element. Of course, when a special circuit connection method is used to realize the opening of the circuit switch in the front section, the circuit in the rear section is powered off, and the wireless communication module of the second element is powered on, the circuit switch in the front section is closed, the circuit in the rear section is powered on, and the wireless communication module of the second element is powered on. The communication module is not powered on. However, no matter which form is adopted, that is to say, the switching of the circuit switch state of the first element will affect the switching of the power-on state of the wireless communication module of the element on the subsequent circuit, so as to feedback and update the wireless communication module of the first element. In the searched identification information set, and the present invention is based on the switching of the circuit switch state and the association relationship between the update of the identification information set searched by the wireless communication module to realize the identification of the topological relationship of the meter box elements, That is, when there is a topological relationship between the first element and the second element, when the circuit switch state of the first element is switched, it will cause the on-off change of the wireless communication module on the second element. The identification information about the second element in the identification information set searched on the element will be updated.

It should be noted that, theoretically, when the circuit switch of only one first element is in the closed state, and the switch states of the remaining first elements are in the open state, it is also possible to directly display the identification information in the set. The identification information is directly determined as the corresponding associated identification information. However, considering that there are a large number of components in the multi-family meter box, if the switch state of each first component is set to the closed state in turn, and the switch state of the remaining first components is set to the open state to achieve For the identification of the relationship between the components of the meter box, most components need to be in a power-off state for a long time, which is not ideal for practical applications.

In this embodiment, since the topology identification of the meter box elements needs to depend on the state switching of the circuit switch, it will inevitably lead to the update of the identification information set. Therefore, the state switching of the circuit switch and the update of the identification information can be regarded as the two perspectives respectively. Judgment of topology identification of meter box components. In fact, considering that the state switching of the circuit switch of the first element leads to the update of the identification information in the identification information set searched by the wireless communication module of the first element, the state switching of the circuit switch is used to judge and update the identification information set. The judgment can be understood as two different identification modes, namely the active identification mode in which the circuit switch is actively controlled to perform state switching and the passive identification mode in which the update of the set of identification information is passively detected. For the specific content, please refer to the following FIG.

Further, after identifying the second element that has a topological relationship with the first element, it is usually written to the topological relationship database, that is, stored locally, so that the topological relationship database can be directly used for maintenance or maintenance in the future. maintenance work. Alternatively, the topology relationship between the first element and the second element may be uploaded to the master station based on a communication technology such as carrier wave, 4G/5G, or Beidou, that is, stored in the server to prevent data loss. Of course, it is also possible to update the topological relational database in real time and upload it to the master station when writing to the topological relational database to prevent data tampering.

The invention provides a method for identifying topology of meter box elements, which is to identify a second element that has a topology relationship with a first element according to updated identification information in an identification information set and state switching information of a circuit switch. Specifically, because the circuit switch associated with the first element will affect the continuity of the subsequent circuit of the element, thereby affecting the continuity of the subsequent circuit elements, the change of the identifier searched by the wireless communication module will be fed back. Therefore, when the state of the circuit switch is switched and a certain identification information in the identification information set changes, it can be considered that there is a topological relationship between the element corresponding to the changed identification information and the first element where the state of the circuit switch is switched, That is, a second element that has a topological relationship with the first element is identified. The method for identifying the topology of the components in the meter box proposed by the present invention is based on the change of the on-off state of the circuit switch and the change of the identification information set searched by the wireless communication module to realize the topological relationship identification of the components in the meter box, with good security and no It will be interfered by the line signal, and the recognition accuracy is high. In addition, the state of the circuit switch can be switched manually or automatically, and the identification can be automatically performed in combination with the change of the searched identification information set, and the identification efficiency is high.

As shown in FIG. 3 , FIG. 3 is a schematic flowchart of a method for determining the topology identification of a meter box element based on a meter box element topology identification mode proposed in an embodiment of the present application.

In some embodiments of the present application, an implementation scheme for executing different identification processes based on different topological identification modes of meter box components is proposed, which specifically includes steps 301 to 303:

301. Determine the identification mode of the topology identification of the meter box element.

In this embodiment, the topology identification mode of the meter box element includes a passive identification mode and an active identification mode. Combining with the description of the foregoing step 202, it can be known that the active identification mode refers to actively controlling the circuit switch to perform state switching to actively start the topology relationship identification process. , and the passive identification mode refers to passively detecting the update of the identification information set. When the update of the identification information set is detected, the process of topological relationship identification is started.

302, if the identification mode is a passive identification mode, when the identification information set is updated, identify the identification information with the first identification information according to the updated identification information in the identification information set and the state switching information of the circuit switch. The element exists in a topological relationship to the second element.

In this embodiment, when the passive identification mode is adopted, at this time, the process of identifying the topology relationship is started by detecting the update of the identification information set, and it is further judged whether there is a circuit switch associated with the update of the identification information set. State switching is used to identify a second element that has a topological relationship with the first element. For specific passive identification rules, please refer to FIG. 4 to FIG. 6 and the contents of their explanations.

303. If the identification mode is an active identification mode, then when the state of the circuit switch is switched, identify a connection with the first circuit switch according to the updated identification information in the identification information set and the state switching information of the circuit switch. An element exists in a topological relationship to a second element.

In this embodiment, when the active identification mode is adopted, the switching of the circuit switch is completed by actively issuing a switching instruction of the circuit switch state. Of course, the switching process can also be completed manually, and further switch the state of the circuit switch. Afterwards, a second element having a topological relationship with the first element is identified according to the updated identification information in the identification information set. For specific passive identification rules, please refer to FIGS. 7 to 8 and their explanations.

It should be noted that, for the multi-family meter box, the active identification mode usually needs to identify the association relationship for each first element in turn, that is, to switch the state of the circuit switch of each first element in turn, so as to complete the The relationship between the components in the entire meter box is identified, and the passive identification mode can monitor all the first components at the same time, and update and adjust the written topology relationship in combination with the updated identification information in the identification information set and the state switching information of the circuit switch. .

In the embodiment of the present application, a scheme of adopting different identification procedures for different topological identification modes of meter box elements is further proposed. Specifically, the active identification mode is suitable for periodic comprehensive identification, while the passive identification mode is suitable for the identification and update of the topological relationship of the meter box components in daily life. For example, the active identification mode is adopted every other quarter, and the switching of the circuit switch is completed by actively issuing the circuit switch state switching command, so as to complete the active identification of the topology relationship of the meter box components, and after the active identification process, switch to passive Identify the mode, and passively update and correct the topological relationship of the identified meter box components by using the accidental tripping and power failure that may exist in daily life. Through the combination of the active mode and the passive mode, the meter box components can be easily and accurately identified. topological relationship between them.

As shown in FIG. 4 , FIG. 4 is a flowchart of a step of determining associated identification information according to an identification information update in an identification information set proposed in an embodiment of the present application.

In the embodiment of the present application, a flowchart of steps for determining the associated identification information according to the identification information update in the identification information set in the passive identification mode is proposed, including steps 401 to 402:

401. When the identification information set is updated, determine whether the circuit switch has switched states within a first time period. When the circuit switch has switched states within the first time period, step 402 is performed; when the circuit switch has not switched states within the first time period, other steps are performed.

In this embodiment, the updating of the identification information set generally includes adding identification information or reducing identification information in the set. Since the identification information set and the state of the circuit switch are continuously acquired in this application, the update change of the identification information in the identification information set can be detected.

It should be noted that, in general, when the set of identification information searched by a first element is updated, that is, the identification information of a second element is added or reduced, it indicates that the wireless communication module of the second element is The on-off state is switched, and at this time, the identification information sets of all the first elements will be updated. Therefore, a subsequent step of judging whether the circuit switch has switched states within the first time period needs to be performed for each first element. If it is determined that the circuit switch of a certain first element has been switched within a period of time, it indicates that the switching of the circuit switch of the first element causes the wireless communication module of the second element to switch the on-off state. If it is determined that the circuit switch of a first element has not been switched within a certain period of time, it means that the wireless communication module of the second element has switched the on-off state and is not associated with the first element. Among them, considering that the switching of the switch state of the circuit will immediately lead to the on-off of the wireless communication module on the subsequent circuit, so as to quickly feedback in the identification information set, therefore, the time threshold set for the first time period is usually short, for example, it can be set to 2 second. And within the first time period refers to the first time period before the update time when the identification information set is updated.

402. Determine the element corresponding to the updated identification information in the identification information set as a second element that has a topological relationship with the first element.

When it is determined that the circuit switch of a first element has been switched within a period of time, it means that the switching of the circuit switch of the first element causes the wireless communication module of the second element to switch the on-off state, then There may be an association relationship between the second element corresponding to the updated identification information in the identification information set and the first element that has undergone switching of the circuit switch state within a certain period of time.

Further, considering that the identification information update mainly includes adding identification information and reducing identification information, and the switching of the circuit switch mainly includes switching from the open state to the closed state and from the closed state to the open state. Therefore, there are correspondingly two specific implementation solutions, which correspond to the subsequent explanations of FIG. 5 and FIG. 6 respectively.

As shown in FIG. 5 , FIG. 5 is a flowchart of another step of determining associated identification information according to the identification information update in the identification information set proposed in the embodiment of the present application.

In the embodiment of the present application, a flowchart of another implementation scheme for determining the associated identification information according to the identification information update in the identification information set in the passive identification mode is proposed, including steps 501 to 502:

501. When identification information is newly added to the identification information set, determine whether the circuit switch is switched from an open state to a closed state within a first time period. When the circuit switch is switched from the open state to the closed state within the first time period, step 502 is executed, and when the circuit switch is not switched from the open state to the closed state within the first time period, Perform additional steps.

502. Determine the element corresponding to the newly added identification information in the identification information set as a second element that has a topological relationship with the first element.

In the embodiment of the present application, when the identification information is newly added to the identification information set, it is necessary to judge whether the circuit switch is switched from the open state to the closed state within the first time period, because only when a certain circuit switch is operated by Only when the open state is switched to the closed state will the subsequent circuit be energized, so that the feedback is that the identification information is added to the identification information set. That is to say, even if a circuit switch undergoes state switching in the first time period, but is switched from the closed state to the open state, then considering the update information of the identification information in the identification information set and the switching information of the circuit switch state No correspondence, that is, it is considered that there is no corresponding relationship between the two elements.

As shown in FIG. 6 , FIG. 6 is a flowchart of another step of determining associated identification information according to the identification information update in the identification information set proposed in the embodiment of the present application.

In the embodiment of the present application, a flowchart of another implementation scheme for determining the associated identification information according to the identification information update in the identification information set in the passive identification mode is proposed, including steps 601 to 602:

601. When the identification information is reduced in the identification information set, determine whether the circuit switch is switched from a closed state to an open state within a first time period. When the circuit switch is switched from the closed state to the open state within the first time period, step 602 is executed; when the circuit switch is not switched from the closed state to the open state within the first time period, Perform additional steps.

602. Determine the element corresponding to the reduced identification information in the identification information set as a second element that has a topological relationship with the first element.

In the embodiment of the present application, based on the same reason, when the identification information is reduced in the identification information set, it is necessary to judge whether the circuit switch is switched from the closed state to the open state in the first time period, because only when a certain The circuit switch is switched from the closed state to the open state, which will cause the power of the rear circuit, so that the feedback in the identification information set reduces the identification information. That is to say, even if a circuit switch undergoes state switching in the first time period, but is switched from the open state to the closed state, then considering the update information of the identification information in the identification information set and the switching information of the circuit switch state No correspondence, it is also considered that there is no corresponding relationship between the two elements.

As shown in FIG. 7 , FIG. 7 is a flowchart of steps for determining association identification information according to a state switching update of a circuit switch proposed in an embodiment of the present application.

In the embodiment of the present application, a flowchart of steps for determining the associated identification information according to the state switching update of the circuit switch in the active identification mode is proposed, including steps 701 to 702:

701. Send a closing command to the circuit switch, so that the circuit switch is switched from an open state to a closed state.

In this embodiment, the active identification mode usually requires active control of the switching state of the circuit switch, such as opening and closing. Generally, electromagnetic technology can be used to automatically realize opening and closing by sending state switching instructions or other feasible methods. , it is also possible to manually open and close. Normally, it is preferable to realize the opening and closing automatically in order to realize the automatic identification of the whole automatic identification mode. The state switching instruction is sent to realize state switching control of the circuit switch on the first element, so as to facilitate subsequent determination of identification information associated with each first element.

In this embodiment, there are usually two ways to control the switching state of the circuit switch. One is to control the circuit switch to close, that is, to send a closing command, so that the circuit switch is switched from the open state to the closed state, and the other One is to open the control circuit switch, that is, to send an opening command, so that the circuit switch is switched from the state of being closed to the state of opening. Figure 7 shows the flow of sending the closing command.

702. Determine the element corresponding to the newly added identification information in the identification information set within the second time period as a second element that has a topological relationship with the first element.

Obviously, after the closing command is sent, that is, after the circuit switch is switched from the open state to the closed state, the corresponding back-end circuit should be switched to the power-on state, so the wireless communication module on the back-end element is powered, and the feedback is in the identification information. Identification information will be added to the set, and at this time, the element corresponding to the newly added identification information in the identification information set in the second time period can be determined as the second element that has a topological relationship with the first element, and The reduced identification information in the identification information set is not the second element that has a topological relationship with the first element. It should be noted that, similar to the first time period, considering that the switching of the switch state of the circuit will immediately lead to the on-off of the wireless communication module on the subsequent circuit, which will be quickly fed back to the identification information set, therefore, the second time period is usually set to The time threshold is also short, for example, it can also be set to 2 seconds. But different from the first time period, the second time period refers to the second time period after the closing command is sent to make the circuit switch switch from the open state to the closed state.

As shown in FIG. 8 , FIG. 8 is a flowchart of another step of determining the associated identification information according to the state switching update of the circuit switch proposed in the embodiment of the present application.

In the embodiment of the present application, a flow chart of the steps of another implementation scheme for determining the associated identification information specifically according to the state switching update of the circuit switch in the active identification mode is proposed, including steps 801 to 802:

801. Send an opening command to the circuit switch, so that the circuit switch is switched from a closed state to an open state.

Similar to the basic flow shown in FIG. 7 , FIG. 8 specifically shows the flow of sending an opening command.

802. Determine, in the identification information set, the element corresponding to the identification information reduced within the second time period as a second element that has a topological relationship with the first element.

Obviously, after the opening command is sent, that is, after the circuit switch is switched from the closed state to the open state, the corresponding back-end circuit should be switched to the off-state, so the wireless communication module on the back-end component is powered off, and the feedback is displayed in the logo. The identification information will be reduced in the information set. In this case, the element corresponding to the identification information reduced in the second time period in the identification information set may be determined as the second element that has a topological relationship with the first element, and the identification The newly added identification information in the information set is not the second element that has a topological relationship with the first element.

In addition, it should be emphasized that although the above describes the specific processes of sending the opening command and sending the closing command separately, in fact, considering that there may be misjudgments in one identification process, usually, it needs to be carried out multiple times. Identification, that is, it is necessary to send the closing command and the opening command in turn for a certain first element to compare the associated identification information obtained each time. Power on, record the second component identified at this time, and then send the closing command to turn on the power, record the second component identified at this time, and compare the two identified second components. When the two are exactly the same, then Indicates that there is no problem with the identified second element, otherwise, re-identification is required.

In this application, considering the actual application process, it should be ensured that the last command sent is the closing command under normal circumstances, so that the power supply can be normally supplied after the active identification of the topological relationship of the meter box components is completed.

As shown in FIG. 9 , FIG. 9 is a schematic flowchart of another method for identifying topology of meter box components proposed by an embodiment of the application. At this time, the meter box is not independently provided with a topology identifying device for meter box components, but The box element topology identification device is integrated on the first element, that is, on the front switch 100 and/or the electricity meter 200, that is, the method for identifying the topology of the meter box element in this embodiment mainly operates on the front switch 100 shown in FIG. 1 . and/or on the electricity meter 200, specifically including steps 901 to 904:

901. Search for identification information based on the wireless communication module to obtain an identification information set.

In the present application, in addition to the functions that the first element should have, a wireless communication module and a meter box element topology identification device should also be integrated, and a circuit switch should also be integrated for an electric meter.

In the present application, the first element may search the remaining wireless communication modules, that is, the identification information of the remaining elements, based on the wireless communication module, and obtain the identification information set.

902. Determine the state of the circuit switch based on the gear position information of the circuit switch.

In this application, for the switch in front of the meter, the state of the switch itself is obvious and can be determined directly, while for the electric meter with a built-in circuit switch, the state of the circuit switch can be determined by judging the gear position information of the circuit switch .

903. If the identification information set is updated or the state of the circuit switch is switched, identify a second element with a topology relationship according to the updated identification information in the identification information set and the state switching information of the circuit switch.

In the present application, the Xi'an process is essentially the same as step 202 in FIG. 2 , for details, please refer to the contents shown in FIGS. 3 to 8 and their explanations.

It can be understood that when the meter box element topology identification device is directly integrated on the first element, the first element can directly identify the second element having a topology relationship with the first element based on the foregoing collected information and rules.

The first element has a topological relationship with the second element.

In some embodiments of the present application, the topological relationship identification module 1002 includes:

Determine the identification mode of the topology identification of the meter box element; the identification mode includes a passive identification mode and an active identification mode;

If the identification mode is a passive identification mode, when the identification information set is updated, according to the updated identification information in the identification information set and the state switching information of the circuit switch, it is recognized that the first element exists the second element of the topological relationship;

Or, when the identification information is reduced in the identification information set, it is judged whether the circuit switch is switched from the closed state to the open state in the first time period; when the circuit switch is in the first time period When the closed state is switched to the open state, the element corresponding to the reduced identification information in the identification information set is determined as a second element that has a topological relationship with the first element.
