In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Fig. 1 is a flow chart illustrating a data processing method according to an embodiment of the disclosure. In some embodiments, the following data processing method is performed by the 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 analysis module reads the content of a preset configuration file of the extension device, and receives service data sent by a terminal device connected with the extension device according to the content of the configuration file of the extension device.
For example, the configuration file of the extension device includes at least one of a type of the extension device, an address of the extension device, configuration information of a communication interface of the extension device, a communication protocol type of the extension device 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 device protocol point location data.
In step 103, the communication protocol parsing module sends the device protocol point location data to an extended device configuration logic module in the extended 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 embodiments of the present disclosure, a communication protocol analysis module and an extension device configuration logic module are set in an extension device, so that service data sent by a terminal device is processed by the communication protocol analysis module to obtain device protocol point location data, and the extension device configuration logic module processes the device protocol point location data according to a preset configuration logic. Therefore, the expansion equipment can process the service data sent by the terminal equipment, so that the load of the controller is effectively reduced.
In some embodiments, the communication protocol analysis 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 data outside the preset range needs to be submitted to the controller for processing. For example, one extension device can process light related data of a specified floor, but cannot process entrance guard related data of the entire building. The expansion device therefore needs to send access related data to the controller.
In some embodiments, the extended device host module sends the device protocol point location data to the controller using a timing transmission manner, so that the controller receives the device protocol point location data at a timing.
In addition, the expansion equipment main control module also sends the equipment protocol point position data to the controller under the condition that the equipment protocol point position data is changed, so that the controller can process the changed equipment protocol point position data in time.
For example, if the difference between the value of the certain device protocol point data at the current time and the value of the previous time is greater than a predetermined threshold, the device protocol point data transmission change is determined.
Fig. 2 is a flow chart illustrating a module configuration method according to another embodiment of the present disclosure. In some embodiments, the following data processing method is performed by the expansion device.
In step 201, after the expansion device main control module in the expansion device is started, a query request is sent to the controller.
The query request includes attribute information of the extension device, so that the controller queries an extension device configuration file, an extension 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 the expansion device configuration file, the expansion device configuration logic file and the communication protocol analysis file from the query response.
For example, the configuration file of the extension device includes at least one of a type of the extension device, an address of the extension device, configuration information of a communication interface of the extension device, a communication protocol type of the extension device and the terminal device, a communication address of the terminal device, and protocol point location information of the terminal device.
For example, in the case where an extension device is connected to one terminal device, the extension device configuration logic file of the extension device includes the configuration of the one terminal device. In the case that an extension device is connected to a plurality of terminal devices, an extension device configuration logic file of the extension device includes a configuration among the plurality of terminal devices connected to the extension device.
In step 203, the expansion device master 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 master control module extracts the expansion device configuration file, the expansion device configuration logic file, and the communication protocol analysis file from the query response, and extracts the first check information of the expansion device configuration file, the second check information of the expansion device configuration logic file, and the third check information of the communication protocol analysis file from the query response.
For example, the first check information may be a check code, a size of an extended device configuration file, and the like. The second check information may be check code, size of configuration logic file of the expansion device, etc. The third check information may be check code, size of the communication protocol analysis file, etc.
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 host 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 both successful, the extension device master control module extracts the attribute information of the extension device from the extension device configuration file.
For example, the attribute information of the expansion device includes at least one of an address of the expansion device and a type of the expansion device.
And the main control module of the expansion equipment judges whether the attribute information is correct. And under the condition that the attribute information is correct, the expansion equipment main control module starts the expansion equipment configuration logic module by utilizing the expansion equipment configuration logic file, and starts the communication protocol analysis module by utilizing the communication protocol analysis file.
In some embodiments, in the event that the attribute information is incorrect, the expansion device host module sends verification failure information to the controller so that the controller resends the query response.

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