The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

The networking of the electric energy meters means that a plurality of electric energy meters and a first device are deployed in the same network, and the first device is used for realizing centralized management and monitoring on the plurality of electric energy meters.

In order to realize networking of the electric energy meters, the first equipment needs to acquire address information of each electric energy meter participating in networking. In the prior art, the addresses of the electric energy meters can be manually input into the first equipment during installation, the equipment is restarted to carry out networking, the mode of manually inputting the addresses of the electric energy meters is more in time consumption, the accuracy is low, and errors are easy to occur.

Based on the method, in the method, the first equipment and the plurality of electric energy meters are connected to the communication bus, the first equipment can acquire address data of each electric energy meter participating in networking from the communication bus, manual participation is not needed, and the efficiency of the first equipment for acquiring the addresses of the electric energy meters is improved. The electric energy meters participating in networking send the first address information based on the delay, so that the situation that the first equipment cannot obtain accurate electric energy meter address information due to the fact that signals of the address information are overlapped on a communication bus is reduced as much as possible, the accuracy of the received address information is guaranteed through inspection, the first equipment can acquire the electric energy meter addresses participating in networking rapidly and accurately, and networking efficiency is improved.

Fig. 1 is a schematic implementation flow chart of a networking method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps S101 to S106:

S101, first equipment broadcasts first information to a plurality of electric energy meters through a communication bus, wherein the first information is used for indicating the electric energy meters to send first address information to the first equipment based on delay time corresponding to the electric energy meters.

The first device is an electronic device having data collection, storage and signal processing capabilities. The first device may be, for example, a concentrator, or a power meter or other electronic device having concentrator functionality.

The first address information is determined by the power meter. The first address information includes: the first address data and the first check data of the electric energy meter; the first verification data is used for verifying the first address data.

The first check data may be odd check data, even check data, redundancy check data, or the like, which may perform odd check, even check, redundancy check, or the like, respectively, on the first address data.

Illustratively, the first parity data is odd parity data for odd parity of the first address data. I.e. the first check data is used to make the sum of the numbers of 1 in the first address data and the first check data odd. Assume that the first address data is: 1001, the first check data is: 1. thus, the first address information may include 5 bits, the first 4 bits are used to represent the first address data, the last 1 bit is used to represent the first check data, and the first address information is: 10011.

It should be noted that the number of bits of the first address data and the number of bits of the first check data are only an example of the present application, and do not constitute a limitation of the technical solution of the present application. In the present application, the number of bits of the first address data and the first check data may be determined according to actual conditions.

After the first device broadcasts the first information, part or all of the plurality of electric energy meters respond to the first information and send first address information to the first device based on corresponding delay. And responding the first information, and successfully sending the first address information to the first equipment, wherein the electric energy meter is the electric energy meter participating in networking.

In some embodiments, the time delay durations corresponding to different electric energy meters may be the same or different.

The method for determining the delay time length for transmitting the first address information by the electric energy meter is not limited. In some embodiments, the electric energy meter may generate the delay time length by using a preset algorithm, or may randomly select a time length within a time length range specified by the host. The duration range may be 0 to a preset duration mentioned below.

In some embodiments, the particular duration range may be carried in the first information. The host computer pre-determines a preset time length before sending the first information, determines a time length range according to the preset time length, and then adds the time length range into the first information and sends the first information to the electric energy meter.

S102, the first device receives second address information through a communication bus.

The first address information is transmitted through the communication bus and becomes second address information.

The second address information includes second address data and second check data.

The delay time of the first address information sent by the plurality of electric energy meters or the time when the plurality of electric energy meters send the first address information are related to the overlapping state of the signals of the plurality of first address information transmitted through the communication bus.

In some embodiments, the manner in which the electric energy meter transmits the first address information through the communication bus is serial transmission, i.e., the communication bus transmits one bit at a time. If the time delay duration/sending time difference of any two first address information is larger than a first threshold value, signals of the two first address information are not overlapped at all. If the difference between the delay time length/the sending time of any two pieces of first address information is greater than 0 and less than the first threshold, signals of the two pieces of first address information may partially overlap. If the delay time/the transmission time of any two pieces of first address information are identical, signals of the two pieces of first address information are completely overlapped.

The first threshold may be the same as a time period between transmission of a start bit in the first address information and transmission of a last bit of the first address information.

In other embodiments, the electric energy meter transmits the first address information through the communication bus in parallel, and the number of bits that can be transmitted by the communication bus at a time is the same as the number of bits of the first address information. In this case, if the delays/times of transmission of the first address information by the electric energy meters participating in the networking are different, the signals of the respective first address information do not overlap at all. If the delay/time of the first address information sent by any two electric energy meters participating in networking is the same, signals of the first address information sent by any two electric energy meters participating in networking are completely overlapped.

The overlapping state of the signals of the first address information is correlated with the acquired second address information.

As described above, if the signal of the first address information is not overlapped with the signal of the first address information sent by another electric energy meter participating in the networking, the second address information is one first address information on the communication bus.

If the signals of the plurality of first address information are overlapped (including the case of partial overlapping and complete overlapping), the second address information is address information obtained by overlapping the signals of the plurality of first address information on the communication bus. Specifically, the signal of the second address information is a composite signal obtained by superimposing the signals of the plurality of first address information.

Fig. 2A, 2B, and 2C show signal timing diagrams in three cases where signals of two first address information are completely non-overlapping, partially overlapping, and completely overlapping, respectively.

As shown in fig. 2A, the first address information sent by the electric energy meter 1 participating in the networking is 10101, the signal waveform thereof is S1, the first address information sent by the electric energy meter 2 participating in the networking is 11001, and the signal waveform thereof is S2. S1 and S2 do not overlap at all. Both S1 and S2 can be accurately received by the first device. I.e. the second address information currently received by the communication bus is a first address information. In which case the second verification data can successfully verify the second address data.

As shown in fig. 2B or fig. 2C, there is an overlap of S1 and S3, in which case neither S1 nor S3 can be received accurately.

Illustratively, in fig. 2B, the manner in which the power meter transmits the first address information is serial transmission. If the electric energy meter 1 is transmitting the 2 nd bit 0 of S1, the electric energy meter 2 starts transmitting the1 st bit 1 of S2. Thus, S1 and S2 partially overlap. After the electric energy meter 1 sends S1, the signal of the second address information corresponding to the first address information sent by the electric energy meter 1 and received by the first device is a composite signal S3 formed by overlapping all bits of S1 and part bits (2 nd to 4 th) of S2, and the second address information corresponding to S3 is: 10100.

The data structure of the second address information is the same as the data structure of the first address information, and the types of the second check data and the first check data are the same. In the second address information 10100, the first 4 bits correspond to second address data, the last bit corresponds to second check data, the number of 1 s in the second address data is 2, and the second check data is 0. The second verification data cannot successfully verify the second address data.

In fig. 2C, S1 and S2 are all overlapped, after the electric energy meter 1 and the electric energy meter 2 send the first address information, the signal S4 of the second address information corresponding to the first address information sent by the electric energy meter 1 or the electric energy meter 2 and received by the first device, S4 is a composite signal formed by overlapping all bits of S1 and all bits of S2, and the second address information is: 10001. wherein the first 4 bits 1000 correspond to the second address data, the last bit 1 corresponds to the second check data, and the second check data cannot successfully check the second address data.

S103, the first device verifies the second address data based on the second verification data; if the verification is successful, executing S104 to continue to verify the next second address data; if the verification fails, the first device determines that the second address information is address information obtained by superposition of signals of a plurality of first address information on the communication bus, and the second address information is not the first address information. In this case, the first device performs S101.

As described above, if the second verification data can successfully verify the second address data, it is indicated that the signal of the first address information sent by the current electric energy meter and the signal of the first address information sent by the other electric energy meters participating in the networking are not overlapped at all, and the first address information can be accurately received by the first device, and one second address information is identical to one first address information.

If the second verification data cannot successfully verify the second address data, it is indicated that the signal of the first address information sent by the current electric energy meter may overlap with the signals of the first address information sent by other electric energy meters participating in networking, and the second address information may be address information formed by overlapping a plurality of signals of the first address information, instead of the first address information itself. That is, the first address information may not be accurately received by the first device.

S104, the first device determines the second address information as first address information on the communication bus, and stores second address data in the second address information into a cache.

The cache may be a static random access memory (Static Random Access Memory, SRAM). Which has a high access speed.

SRAM is a volatile memory that relies on power supplied by a power source. Data in SRAM is also lost when power is lost.

S105, the first equipment performs verification based on the received second address information, and whether second address data corresponding to the first address data of all the electric energy meters participating in networking are successfully verified or not is determined; if yes, executing S106; otherwise, continuing to execute S101 to S105 until the second address data corresponding to the first address data of all the electric energy meters participating in networking are checked successfully.

S104 describes a procedure of checking one second address information received currently, S105 describes checking at least one second address information received subsequently.

The second address information is checked, that is, the second address data is checked using the second check data.

When the second address information is checked, it may be that the second address information is checked after being received. And if the verification is successful, storing the second address data into the cache, and then verifying the next address data, and the like until whether the second address data corresponding to the first address data of all the electric energy meters participating in networking are verified successfully or not. If the second address information received fails to be checked during the checking process, the process returns to S101 after the second address information fails to be checked, and the second address data received next does not need to be checked again.

In some embodiments, the verification of the second address data corresponding to the first address data of all the electric energy meters participating in the networking may be determined to be successful by the following method:

The first device checks all second address information received within a preset time after broadcasting the first information, and the second address information is checked successfully.

In some embodiments, the preset duration is related to the number of meters participating in the networking and a delay threshold for the meter transmission delay.

Specifically, the preset threshold is positively correlated with the number of electric energy meters participating in the networking. And the preset time length is larger than a delay threshold value of the transmission delay of the electric energy meter.

And S106, the first equipment writes all second address data in the cache into the first memory, and networking is carried out according to all second address data in the first memory.

If any second address data received is checked, and the check is unsuccessful, the second address data in the cache is not written into the first memory, and when the execution is returned to S101, all the second address data stored in the cache are released.

It will be appreciated that only after the second address data has been successfully verified, the second address data that has been fully verified is written into the first memory. And writing one instead of checking success, checking again, and checking success and writing again. The mode of writing the second address data into the first memory in batches can save the waiting time of the first memory, and is beneficial to saving electricity of the first memory.

The first Memory may be a nonvolatile Memory such as an EEPROM (ELECTRICALLY ERASABLE PROGRAMMABLE READ-Only Memory) FLASH Memory (Firmware, lighting-ACCELERATED STORAGE, hot-pluggable, FLASH) or a ferroelectric random access Memory (Ferroelectric Random Access Memory, FRAM), which does not lose data when power is turned off. And the stability of data storage is ensured.

After the second address data is written into the first memory, the second address data is always present if not actively deleted by the first device. After each power-on, the first equipment can perform communication connection and data interaction according to own requirements and the second address data and the electric energy meter corresponding to the second address data so as to realize management and control of the electric energy meter.

The electric energy meter sends first address information to the first device through the communication bus, and accordingly, the first device receives second address information. If the delays of the sending of the first address information by the electric energy meters are different, signals of the first address information on the communication bus are not overlapped, the second address information is the first address information, and the second address information can be checked successfully. If the delays of the first address information sent by any two electric energy meters are the same, signals of the first address information on the communication bus are overlapped, the second address information is formed by overlapping signals of a plurality of first address information, and verification of the second address information may fail. The networking method provided by the application checks the accessed second address information, and networking is performed when all the second address information corresponding to the first address information sent by the electric energy meter participating in networking is checked successfully. The whole process does not need to be manually participated, and automatic networking can be realized to improve networking efficiency. And the delay of the electric energy meter for sending the first address information does not need to be specially planned and calculated to ensure that the delay of each electric energy meter for sending the first address information is different. Even if the delay of the first address information is the same, the electric energy meter further checks the second address information after receiving the second address information, networking is performed only after the second address information corresponding to all the electric energy meters participating in networking is successfully checked, and networking accuracy is guaranteed while calculation resources of the electric energy meters are saved.

As described above, the communication bus is connected with the first device and the plurality of electric energy meters, address information of any electric energy meter may not be stored in the first device, address information of part of electric energy meters may also be stored in the first device, and electric energy meters not stored with address information are all electric energy meters needing networking. After the first device broadcasts the first information, ideally, each electric energy meter needing to be networked successfully sends the first address information to the first device to participate in the networking so as to participate in the networking.

In some special cases, for example: if a certain electric energy meter which needs networking is in poor contact with an interface connected with a communication bus, and data transmission is abnormal or data cannot be transmitted, the electric energy meter may not successfully send first address information to first equipment. And the second address data corresponding to the electric energy meter is not included in the second address data successfully checked by the first equipment. In this case, the first device needs to request the user whether to continue the networking operation, continue the networking operation according to the user instruction, or rebroadcast the first information to re-network.

The fig. 3 and 4 embodiments describe the process flow of the first device in the case where the user indicates that networking operation is allowed and the user indicates that networking operation is not allowed, respectively.

Fig. 3 is a schematic implementation flow chart of a networking method according to an embodiment of the present application. As shown in fig. 3, the networking method further includes S106a to S106b before S106 in the embodiment of fig. 1:

And S106a, the first equipment outputs a first request, wherein the first request comprises the total number of the second address data stored in the cache, and the first request is used for requesting a user to confirm whether networking is allowed for the electric energy meters corresponding to all the second address data.

The total number of the second address data stored in the cache is the number of the second address data which is received and checked successfully after the first device broadcasts the first information.

The first request may be output in the form of text prompt information or in the form of voice prompt information, which is not limited in the present application.

Illustratively, the first request is output in the form of a text prompt, and the first request may further include two options: allowing and disallowing continued networking.

And S106b, the first equipment receives a first instruction, and the first instruction indicates that networking of the electric energy meters corresponding to all the second address data is allowed.

The first instruction is sent by the user. In some embodiments, the user may send the first instruction to the first device in the form of voice. In other embodiments, the option for allowing to continue networking corresponds to a first instruction. The user may send the first instruction by touching the option or clicking a key corresponding to the option.

Illustratively, if the user sends the first instruction to the first device in the form of voice, the first device starts the voice detection function, and when voice information related to "allow to continue networking" is detected, S106 is performed.

Or if the user transmits the first instruction by touching/clicking the option/key associated with the first instruction, the first device performs S106 after detecting the touch/key operation of the user in the specific area.

In this embodiment, before writing the second address data in the buffer memory into the first memory for networking, the first device requests the user to determine whether to allow networking according to the number of the second address data, and if the user allows networking, S106 is executed to write the second address data into the first memory for networking.

Fig. 4 is a schematic implementation flow chart of another networking method of an electric energy meter according to the embodiment of the present application, fig. 4 mainly describes an execution flow of the first device when the user indicates that networking is not allowed, and fig. 4 further includes S106c after S106 a:

s106c, the first equipment receives a second instruction; the second instruction indicates that networking of the electric energy meter corresponding to the second address data is not allowed.

The first device returns to execute S101 in response to the second instruction.

The second instruction is sent by the user. In some embodiments, the user may send the second instruction to the first device in the form of voice. In other embodiments, the option that does not allow to continue networking corresponds to a second instruction. The user may send the second instruction by touching the option or clicking a key corresponding to the option.

Illustratively, if the user sends the second instruction to the first device in the form of voice, the second device starts the voice detection function, and when voice information related to "no network connection is allowed" is detected, S101 is executed.

Or if the user transmits the second instruction by touching/clicking the option/key associated with the second instruction, the first device performs S101 after detecting the touch/key operation of the user in the specific area.

In this embodiment, before writing the second address data in the buffer memory into the first memory to perform networking, the first device requests the user to determine whether to allow networking according to the number of the second address data, and returns to execute S101 if the user does not allow networking, and rebroadcasts the first information to reacquire the address data of the electric energy meters participating in networking.

In some embodiments, the user may send a fifth instruction, the fifth instruction indicating that the first device ends networking. The first device ends the current flow in response to the fifth instruction after receiving the fifth instruction.

As described in the previous embodiment, if the signal of the second address information is obtained by overlapping the signals of the plurality of first address information, the verification of the second address information may fail. However, the signal verification of the second address information obtained by superimposing the signals of the plurality of first address information is not excluded. For example, the signal S5 of one first address information 11001 and the signal S6 of the other first address information 10110 are superimposed in such a manner that the 2 nd bit to the 5 th bit of S5 are respectively superimposed with the 1 st bit to the 4 th bit of S6, and the second address information corresponding to the superimposed composite signal is 11001. In the second address information, although the second verification data may successfully verify the second address data. However, the second address information and the two first address information are not identical, and there is no electric energy meter which can correspond to the second address information among the plurality of electric energy meters.

To avoid this, it is necessary to determine whether the second address data can correspond to one of the plurality of electric energy meters after checking all the second address data.

Based on this, the embodiment of the application provides a networking method of an electric energy meter, and fig. 5 is a schematic implementation flow diagram of the networking method of the electric energy meter provided by the embodiment of the application. As shown in fig. 5, the method further needs to perform the following S1061a to S1062a before S106 a.

S1061a, the first device sends address acknowledgement response information to the communication bus in a unicast manner for each second address data in the cache, so that the communication bus transmits the address acknowledgement response information according to the second address data.

S1062a, the first device confirms whether all the second address data in the cache have corresponding address confirmation response information. If yes, executing S106a to request the user to indicate whether to continue networking; otherwise, S101 is performed to rebroadcast the first information to reorganize the network.

The conditions for executing S106a are specifically: the first device confirms that all second address data in the cache have corresponding address confirmation response information.

The conditions for executing S101 specifically include: and all the second address data in the first equipment confirmation buffer memory does not have corresponding address confirmation response information, or part of the second address data in the first equipment confirmation buffer memory has corresponding address confirmation response information.

For each second address data, if the first device receives address confirmation response information for the second address data, the first device determines that the second address data has the corresponding address confirmation response information. The second address data exists address confirmation response information indicates that one electric energy meter exists in the electric energy meters participating in networking and corresponds to the second address data.

If the first device does not receive the address confirmation response information for the second address data, the first device determines that the second address data does not have the corresponding address confirmation response information. The absence of the corresponding address confirmation response information of the second address data indicates that one electric energy meter which participates in networking does not exist in the electric energy meters corresponding to the second address data.

In this embodiment, before the first device requests the user to confirm whether to continue networking, for each second address data in the cache, it is determined whether the electric energy meter participating in networking exists in the electric energy meter corresponding to the second address data, and if the electric energy meter corresponding to each second address data exists, the networking operation is continuously executed. Otherwise, continuing to broadcast the first information to reacquire the address data of each electric energy meter participating in the networking.

In the embodiment of fig. 1, after the first device broadcasts the first information to the plurality of power meters via the communication bus, there are two cases: case 1: the first device receives at least one second address information through the communication bus within a preset time period. Case 2: the first device does not receive the second address information within a preset duration. The first device receives the second address information differently, and the first device executes the process.

The application provides a networking method of an electric energy meter, which aims at the two different conditions and shows two different processing flows of first equipment.

Fig. 6 is a schematic implementation flow chart of a networking method of an electric energy meter according to an embodiment of the present application, as shown in fig. 6, in case 1, a first device implements S102 through the following S1021. In case 2, the first device continues to return to executing S101 after S101.

S1021, the first device receives the second address information through the communication bus within a preset time period.

The preset time length is positively correlated with the number of the electric energy meters participating in networking, or the preset time length is correlated with the number of the electric energy meters needing networking.

And the slave electric energy meter sends the first address information to the first equipment based on the delay, and the delay generated by the slave electric energy meter participating in networking is smaller than or equal to a delay threshold value.

The preset time period is longer than the delay threshold.

It can be understood that if the number of electric energy meters participating in networking or needing networking is large, if each electric energy meter sends first address information to first equipment according to different delays, the first equipment needs to wait for a long time to receive second address information corresponding to the last first address information; in this case, the preset time period may be set longer. If the number of the electric energy meters participating in networking or needing networking is smaller, the waiting time of the first equipment for receiving the second address information corresponding to the last first address information is shorter; in this case, the preset time period may be set shorter.

In this embodiment, if the first device receives the second address information within the preset time period, the second address information is checked. If the second address information is not received after waiting for the preset time, rebroadcasting the first information.

Before S101 is not performed, the first device may be networked with some of the electric energy meters, and thus the first memory may store therein the third address data of the historically networked electric energy meters, or the first device may not store therein the third address data. The first memory has different storage states for the third address data, and the processing flow of the first device is different.

Fig. 7 is a schematic implementation flow diagram of the networking method of the electric energy meter, as shown in fig. 7, before S101, the method further needs to execute the following S101a to determine a storage state of the first memory for the third address data. When the first memory stores one or more third address data, S101 is performed. If the third address data is not stored in the first memory, the following S101b is performed.

S101a, the first device responds to a power-on operation and determines whether one or more third address data are stored in a first memory; if yes, executing S101b; otherwise, S101 is performed.

The third address data may be address data of an electric energy meter which is historically completed to form a network before the current power-on, and the electric energy meter may be connected to the communication bus at present or disconnected from the communication bus.

The conditions for executing S101b are specifically: one or more third address data are stored in the first memory.

The conditions for executing S101 are specifically: the third address data is not stored in the first memory.

S101b, the first equipment determines whether an electric energy meter corresponding to the third address data is on line or not according to each third address data; if all the corresponding electric energy meters in the one or more third address data are online, S101 is executed. If the corresponding electric energy meter in the one or more third address data is partially or entirely on-line, S101c is executed.

In some embodiments, the first device may determine whether the electric energy meter corresponding to the third address data is online by:

The first device sends an address confirmation request to the communication bus based on the third address data, and if response information for the address confirmation request can be received within a certain time, the electric energy meter corresponding to the third address data is determined to be online. If the response information for the address confirmation request is not received within a certain time, determining that the electric energy meter corresponding to the third address data is offline.

And S101c, the first equipment outputs a second request, wherein the second request is used for requesting a user to confirm whether the third address data corresponding to the offline electric energy meter are deleted or whether the electric energy meter corresponding to the third address data are online or not according to each third address data.

It will be appreciated that the electric energy meter corresponding to the third address data is offline, and it may be that the electric energy meter corresponding to the third address data is not on the communication bus, or is connected to the communication bus but is abnormally connected. At this time, the user may respond to the first request based on the state of the electric energy meter corresponding to the third address data.

If the electric energy meter corresponding to the third address data is not on the communication bus, the user can instruct the first device to delete the third address data. If the electric energy meter corresponding to the third address data is on the communication bus but is abnormally connected with the communication bus, a user can perform abnormal processing on the electric energy meter which is abnormally connected, so that whether the electric energy meter is on line is confirmed again after the electric energy meter works normally.

Specifically, if the user confirms that the third address data corresponding to the offline electric energy meter is deleted for the case where the corresponding electric energy meter in the one or more third address data is partially or entirely offline, the first device performs the following S101d to S101e, and if the user confirms that the electric energy meter corresponding to the third address data is again confirmed for each third address data for the case where the corresponding electric energy meter in the one or more third address data is partially or entirely offline, the first device performs the following S101f to S101g.

S101d, the first device receives a third instruction. The third instruction is used for indicating to delete third address data corresponding to the offline electric energy meter.

The electric energy meter is offline, i.e. the electric energy meter is not online.

S101e, the first equipment responds to a third instruction, deletes third address data corresponding to the offline electric energy meter, and then executes S101 to start networking operation.

It should be noted that, when the networking flow of S101 to S106 is executed, the electric energy meter that sends the first address information to the first device is the electric energy meter that participates in the networking, where the electric energy meter includes the electric energy meter that the history of connection on the communication bus is not successful in networking with the first device, and the memory of the first device has no address data stored therein.

S101f, the first equipment receives a fourth instruction, wherein the fourth instruction is used for indicating whether the electric energy meter corresponding to each third address data is on line or not.

Accordingly, the first device returns to execute S101b in response to the fourth instruction.

The embodiment of the application provides a networking method of an electric energy meter, which describes an interaction flow of the electric energy meter participating in networking and first equipment.

Fig. 8 is an interaction schematic diagram of a networking method of an electric energy meter provided by an embodiment of the present application, and fig. 8 illustrates a first device and any electric energy meter participating in networking as an example.

s801, the first device broadcasts first information to the electric energy meter through the communication bus.

Accordingly, the electric energy meter receives the first information.

The determination mode of the delay time length of the electric energy meter is not limited, and the delay time length can be randomly generated based on a delay threshold value, so that the generated delay time length is smaller than the delay threshold value.

S803, the electric energy meter detects that no data is transmitted on the current communication bus, and sends first address information to the first device based on the delay time length.

It will be appreciated that if the first device transmits the first address information when there is a data transmission on the communication bus, the signal of the first address information overlaps with the data signal on the bus after the first device transmits the first address information, and the data signal on the communication bus detected by the first device is different from the signal of the first address information.

And sending the first address information to the first device based on the delay time length, namely starting timing from 0, and sending the first address information when the timing time length reaches the delay time length.

If the electric energy meter detects that data transmission exists on the current communication bus, the electric energy meter waits for sending first address information based on delay time length when the data transmission exists on the communication bus.

S804, the first device receives the second address information through the communication bus.

S805, the first device verifies the second address data based on the second verification data; if the verification is successful, S806 is performed, otherwise S801 is performed.

S806, the first device stores the second address data in the second address information in the buffer, and S807 is executed.

S807, the first equipment performs verification based on the received second address information, and determines whether second address data corresponding to the first address data of all the electric energy meters participating in networking are successfully verified; if so, S807 is performed; otherwise, S801 is executed.

And S808, the first device writes all second address data in the cache into the first memory, and networking is performed according to all second address data in the first memory.
