Correspondingly, the data processing device is also used for acquiring the data of the sub-equipment indicated by the sub-equipment data acquisition request and feeding back the corresponding data to the server when the sub-equipment data acquisition request sent by the server is received; and when receiving the sub-equipment control request sent by the server, carrying out corresponding operation on the sub-equipment indicated by the sub-equipment control request according to the sub-equipment control request.

Referring to fig. 2, a schematic flow chart of a method for device addition provided in an embodiment of the present application is shown, where the method for device addition is applied to the system for device addition shown in fig. 1, where a sub-device in the system for device addition is a meter, a data processing apparatus is a meter data processing apparatus, and the following description is made by taking the sub-device as a meter and the data processing apparatus as a meter data processing apparatus for parsing, where the method for device addition specifically includes the following steps:

s201: the meter data processing apparatus sends a child device list synchronization request to the server.

In the embodiment of the application, the preset synchronization time for sending the sub-device list synchronization request to the server can be set in the meter data processing device in advance, and then the meter data processing device can detect the current time of the meter data processing device in real time, and when the current time is detected to reach the preset synchronization time, the sub-device list synchronization request can be sent to the server. Wherein the meter data processing device may be a gateway.

It should be noted that the identifier of the meter data processing device is carried in the child device list synchronization request, and for convenience of distinction, the identifier of the meter data processing device carried in the child device list synchronization request may be referred to as a second identifier.

It should also be noted that the identifier of the meter data processing device carried in the kid device list synchronization request may be a hash value of the meter data processing device, a timestamp, a version number of the meter data processing device, or the like.

S202: the server receives a sub-device list synchronization request sent by the meter data processing device, and acquires a first mark corresponding to the meter data processing device based on the sub-device list synchronization request.

In this application embodiment, if a user wants to add a corresponding new add sub-device to a meter data processing device, the association relationship between the meter data processing device and a meter to be added can be entered into a database of a server, and when the server receives the association relationship entered by the user, the server will store the received association relationship into the database after clearing the mark of the meter data processing device, which is stored in the database in advance.

In the embodiment of the present application, the identifier of the meter data processing device originally stored in the database may be a hash value, a timestamp, a version number of the meter data processing device, or the like.

It should be noted that the meter can be an intelligent water meter, an intelligent electric meter, a gas meter, an intelligent lock, and the like. When the strapping table is the water gauge, the strapping table data processing device can be a water gauge collector.

In the specific execution of step S202, upon receiving a sub-device list synchronization request from a meter data processing apparatus, the flag corresponding to the meter data processing device may be retrieved from the database in accordance with the kid device list synchronization request (for ease of distinction, the flag corresponding to the meter data processing device retrieved from the database may be referred to as the first flag), if the database stores the incidence relation between the newly added meter and the meter data processing device, the first flag stored in the meter data processing device in the database is 0, and when the first flag is compared with the second flag, it can be determined that the first flag and the second flag are not identical, a sub-device list file associated with the meter data processing apparatus may then be generated to add the corresponding meter to the meter data processing apparatus based on the generated sub-device list file.

If the incidence relation between the newly added meter input by the user and the meter data processing device is not stored in the database, the first mark stored in the meter data processing device in the database is not changed, at the moment, the first mark and the second mark are compared, the first mark and the second mark can be determined to be consistent, and further the meter corresponding to the meter data processing device in synchronization can not be needed.

Correspondingly, when receiving the sub-device list synchronization request sent by the meter data processing device, the server can acquire the first mark of the meter data processing device from the database through the meter data processing device according to the sub-device list synchronization request.

Further, in this application embodiment, if a user wants to delete a corresponding meter in the meter data processing device, the association relationship between the meter data processing device and the meter may be entered into the database of the server, and when receiving the association relationship entered by the user, the server will store the received association relationship into the database after clearing the mark of the meter data processing device, which is stored in the database in advance.

Correspondingly, when the server receives a sub-device list synchronization request sent by the meter data processing device, the server can acquire a first mark corresponding to the meter data processing device from the database according to the sub-device list synchronization request, if the incidence relation between the meter to be deleted and the meter data processing device, which is input by a user, is stored in the database, the first mark stored in the meter data processing device in the database is 0, at this time, the first mark and the second mark are compared, the first mark and the second mark can be determined to be inconsistent, and then a sub-device list file related to the meter data processing device can be generated, so that the corresponding meter can be deleted in the meter data processing device according to the generated sub-device list file.

It should be noted that the meter can send a corresponding registration command to the server by relying on a communication link of a website, after the registration is successful, a user can poll the registration state of the meter through the client, and if the registration state of the meter is determined to be the registration completion, a binding request can be sent to the meter, so that the association relationship between the meter and the client is established in the database.

S203: the server compares the first mark with the second mark; if the first flag and the second flag are not consistent, step S204 is executed.

In the process of specifically executing step S203, after the server obtains the second flag corresponding to the meter data processing apparatus from the database according to the received sub-device list synchronization request, the server may compare the first flag with the second flag, and if the first flag is consistent with the second flag, it may be determined that the database does not store the association relationship between the newly added meter entered by the user and the meter data processing apparatus, and then the corresponding meter may not be synchronized with the meter data processing apparatus.

If the first mark and the second mark are inconsistent, the incidence relation between the newly added meter recorded by the user and the meter data processing device stored in the database can be determined, and then a sub-device list file related to the meter data processing device can be generated, so that the corresponding meter is added to the meter data processing device according to the generated sub-device list file.
