It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be discussed further in subsequent figures.
Fig. 1 is a schematic flow chart of a data processing method according to an embodiment of the present disclosure. In some embodiments, the following data processing method is performed by an expansion device.
In step 101, a communication protocol parsing module in the extension device receives service data sent by a terminal device connected to the extension device.
In some embodiments, the communication protocol parsing module reads the content of a preset expansion device configuration file, and receives service data sent by a terminal device connected to the expansion device according to the content of the expansion device configuration file.
For example, the extended device configuration file includes at least one of a type of the extended module, an address of the extended module, communication interface configuration information of the extended module, a communication protocol type of the extended module and the terminal device, a communication address of the terminal device, and protocol point location information of the terminal device.
In step 102, the communication protocol parsing module processes the service data to obtain the device protocol point location data.
In step 103, the communication protocol parsing module sends the device protocol point location data to an expansion device configuration logic module in the expansion device.
In step 104, the extended device configuration logic module processes the device protocol point location data according to a preset configuration logic.
In the data processing method provided in the foregoing embodiment of the present disclosure, the communication protocol analysis module and the extended device configuration logic module are arranged in the extended device, so that the communication protocol analysis module processes the service data sent by the terminal device to obtain the device protocol point location data, and the extended device configuration logic module processes the device protocol point location data according to the preset configuration logic. Therefore, the expansion equipment can process the service data sent by the terminal equipment, thereby effectively reducing the load of the controller.
In some embodiments, the communication protocol parsing module sends the device protocol point location data to an expansion device main control module in the expansion device, and the expansion device main control module sends the device protocol point location data to the controller, so that the controller processes the device protocol point location data according to a preset configuration logic.
It should be noted that each expansion device can only process data within a preset range, and for data outside the preset range, the data needs to be submitted to the controller for processing. For example, an expansion device can process light related data for a given floor, but cannot process entrance related data for the entire building. The expansion device therefore needs to send access-related data to the controller.
In some embodiments, the extended device main control module sends the device protocol point location data to the controller in a timing transmission manner, so that the controller receives the device protocol point location data at regular time.
In addition, the expansion device main control module also sends the device protocol point location data to the controller under the condition that the device protocol point location data changes, so that the controller can process the changed device protocol point location data in time.
For example, if the difference between the value of a certain device protocol point location data at the current time and the value at the previous time is greater than a predetermined threshold, it is determined that the device protocol point location data is changed in transmission.
Fig. 2 is a schematic flow chart of a module configuration method according to another embodiment of the present disclosure. In some embodiments, the following data processing method is performed by an expansion device.
In step 201, after an expansion device main control module in an expansion device is started, an inquiry request is sent to a controller.
The query request includes attribute information of the expansion device, so that the controller queries an expansion device configuration file, an expansion device configuration logic file and a communication protocol analysis file corresponding to the attribute information.
In step 202, after receiving the query response sent by the controller, the expansion device main control module extracts an expansion device configuration file, an expansion device configuration logic file, and a communication protocol analysis file from the query response.
For example, the extended device configuration file includes at least one of a type of the extended module, an address of the extended module, communication interface configuration information of the extended module, a communication protocol type of the extended module and the terminal device, a communication address of the terminal device, and protocol point location information of the terminal device.

Under the condition that the expansion equipment is connected with a plurality of terminal equipment, the expansion equipment configuration logic file of the expansion equipment comprises the configuration among the plurality of terminal equipment connected with the expansion equipment.
In step 203, the expansion device main control module stores the expansion device configuration file, starts the expansion device configuration logic module by using the expansion device configuration logic file, and starts the communication protocol analysis module by using the communication protocol analysis file.
In some embodiments, the expansion device main control module extracts, from the query response, first verification information of the expansion device configuration file, second verification information of the expansion device configuration logic file, and third verification information of the communication protocol parsing file, in addition to the expansion device configuration file, the expansion device configuration logic file, and the communication protocol parsing file.
For example, the first check information may be check code, size of the extended device profile, and the like. The second check information may be check code, size of the extended device configuration logic file, and the like. The third check information may be check code, size of the communication protocol analysis file, and the like.
The expansion equipment main control module performs first verification on the expansion equipment configuration file by using the first verification information, performs second verification on the expansion equipment configuration logic file by using the second verification information, and performs third verification on the communication protocol analysis file by using the third verification information.
If the first check, the second check and the third check are successful, the expansion equipment main control module starts the expansion equipment configuration logic module by using the expansion equipment configuration logic file, and starts the communication protocol analysis module by using the communication protocol analysis file.
In some embodiments, if at least one of the first check, the second check and the third check is unsuccessful, the expansion device main control module sends check failure information to the controller, so that the controller resends the query response.
In some embodiments, if the first check, the second check, and the third check are all successful, the extended device main control module extracts the attribute information of the extended device from the extended device configuration file.
For example, the attribute information of the extension apparatus includes at least one of an address of the extension apparatus and a type of the extension apparatus.
And the expansion equipment main control module judges whether the attribute information is correct or not. And under the condition that the attribute information is correct, the expansion equipment main control module starts the expansion equipment configuration logic module by using the expansion equipment configuration logic file, and starts the communication protocol analysis module by using the communication protocol analysis file.
In some embodiments, in the case that the attribute information is incorrect, the expansion device main control module sends the verification failure information to the controller, so that the controller resends the query response.

The expansion device main control module 33 performs first verification on the expansion device configuration file by using the first verification information, performs second verification on the expansion device configuration logic file by using the second verification information, and performs third verification on the communication protocol analysis file by using the third verification information.
If the first check, the second check and the third check are successful, the expansion device main control module 33 starts the expansion device configuration logic module by using the expansion device configuration logic file, and starts the communication protocol analysis module by using the communication protocol analysis file.
