[0026] The embodiment of the present application provides a data upgrade processing method, which can be applied to a device group that communicates via an industrial field bus, wherein the industrial field bus can be an RS485 bus, a CAN bus, or a Profibus bus, etc. Figure 2 As shown, the method includes: Step S201: Any device in the device group receives firmware upgrade data; Device firmware refers to programs embedded in hardware devices, usually stored in non-volatile memory (such as ROM, EPROM, EEPROM or Flash Memory). The main function of firmware is to provide the basic instruction set required for the hardware device to start and run, and to realize the communication between the device and the operating system; The way in which any one of the devices receives the firmware upgrade data includes: receiving in a unicast manner or receiving in a broadcast manner; the unicast manner means that the firmware upgrade data is sent to a specific device; the broadcast manner means that the firmware upgrade data is sent to all devices in the device group; Step S202: For the device that receives the firmware upgrade data: In the case where the firmware upgrade data can be used for the firmware of the present device, the firmware upgrade data is used to upgrade the present device; in the case where the firmware upgrade data cannot be used for the firmware of the present device, a processing method for the firmware upgrade data is determined based on a receiving method of the firmware upgrade data; wherein the processing method includes: forwarding the firmware upgrade data to other devices in the device group via the industrial field bus, or discarding the firmware upgrade data.

[0027] The data upgrade processing method recorded in the embodiment of the present application supports, for any device in the device group, after receiving firmware upgrade data, forwarding the firmware upgrade data to other devices in the device group through a connection bus when the firmware upgrade data cannot be used for the firmware of the device itself, thereby facilitating other devices to perform upgrade operations based on the firmware upgrade data, overcoming the deficiency that only one device can be upgraded by performing one upgrade processing operation, and improving upgrade efficiency.

[0028] In an exemplary embodiment, the method further comprises: In the case that the firmware upgrade data can be used for the firmware of the device, after the device is upgraded using the firmware upgrade data, a processing method for the firmware upgrade data is further determined according to a receiving method of the firmware upgrade data.

[0029] In an exemplary embodiment, determining a processing method for the firmware upgrade data according to a receiving method of the firmware upgrade data may include: In the case where the firmware upgrade data is received via unicast, the firmware upgrade data is broadcast to other devices in the device group via the industrial field bus, wherein the unicast method includes at least one of: point-to-point transmission via wireless, point-to-point transmission via the industrial field bus, and point-to-point transmission via a serial port.

[0030] In this embodiment, when a device (represented by device A) in the device group receives the firmware upgrade data in a unicast manner, if the firmware upgrade data cannot be used for device A, device A forwards the firmware upgrade data to other devices in the device group, which is beneficial for other devices in the device group that need the upgrade data to perform firmware upgrade. If the firmware upgrade data can be used for device A, device A still forwards the firmware upgrade data to other devices in the device group, which is beneficial for other devices of the same type as device A in the device group to also use the upgrade data for firmware upgrade.

[0031] In another exemplary embodiment, determining a processing method for the firmware upgrade data according to a receiving method of the firmware upgrade data may include: In the case where the firmware upgrade data is received via broadcast, the firmware upgrade data is discarded; the broadcast mode includes: receiving via the industrial field bus broadcast and receiving via wireless broadcast. Exemplarily, the device with a Bluetooth communication module receives the broadcasted firmware upgrade data via a Mesh network.

[0032] In this embodiment, when a device in the device group (represented by device A) receives the firmware upgrade data by broadcasting, considering that other devices in the device group will also receive the firmware upgrade data, device A may subsequently discard the received firmware upgrade data.

[0033] In an exemplary embodiment, the firmware upgrade data includes: the type of device to which the firmware belongs and the upgrade firmware version number, Figure 3 A data packet format of firmware upgrade data is shown. Taking the bathroom field as an example, the type of equipment can be a panel (corresponding size, whether it is a touch panel, etc.), a controller, an amplifier, a light controller, etc.

[0034] Correspondingly, the method for determining whether the firmware upgrade data can be used for the firmware of the device includes: In the case where it is determined that the device type in the firmware upgrade data is the type of the present device, and the upgrade firmware version number in the firmware upgrade data is higher than the current version number of the firmware of the present device, determining that the firmware upgrade data can be used for the firmware of the present device; In the case where it is determined that the device type in the firmware upgrade data does not match the type of the device, and the upgrade firmware version number in the firmware upgrade data is equal to or lower than the current version number of the firmware of the device, it is determined that the firmware upgrade data cannot be used for the firmware of the device; Exemplarily, the type of device 1 and device 2 are both panel A, the current version number of device 1 is V10, and the current version number of device 2 is V11; device 1 receives firmware upgrade data containing panel A and version number V11 through the bus, and determines that the device type in the firmware upgrade data is consistent with the type of the current device and the version number is higher than the current version number of the current device, and then upgrades to version V11 according to the firmware upgrade data; device 2 also receives the firmware upgrade data through the bus. Although the device type in the firmware upgrade data is the same as the type of the current device, the version number is equal to the current version number of the current device, and then the firmware upgrade data will not be used for upgrading.

[0035] The embodiment of the present application also provides a data upgrade processing method, which is applied to a device group communicating through an industrial field bus, and a control device communicating with the device group, such as Figure 4 As shown, the method may include: Step S401: Control the device to send firmware upgrade data to at least one upgradeable device in the device group; The control device may send the firmware upgrade data to the upgradeable device through a preset communication mode, wherein the preset communication mode includes: at least one of industrial field bus communication and wireless communication; in each preset communication mode, the control device may select unicast or broadcast mode to send the firmware upgrade data; Step S402: Any upgradeable device in the device group processes the firmware upgrade data according to the data upgrade processing method described in any of the above embodiments.

[0036] The data upgrade processing method recorded in the embodiment of the present application supports, for any upgradeable device in the device group, after receiving firmware upgrade data, forwarding the firmware upgrade data to other upgradeable devices in the device group through a connection bus when the firmware upgrade data cannot be used for the firmware of the device, thereby facilitating other upgradeable devices to perform upgrade operations according to the firmware upgrade data, overcoming the deficiency that only one device can be upgraded by performing one upgrade processing operation, and improving upgrade efficiency.

[0037] In an exemplary embodiment, the method further comprises: Before the control device sends the firmware upgrade data to at least one upgradeable device in the device group, any upgradeable device sends its own device type and current firmware version number to the control device via broadcasting, wherein the broadcasting method includes at least one of broadcasting via the industrial field bus and broadcasting via wireless. The format of the data packet broadcasted by the upgradeable device can refer to Figure 3; Exemplarily, the data packet can be distinguished as a broadcast data packet or a unicast data packet by other data parts in the data packet, and the source of the data packet is an upgradeable device or a control device; The control device saves the received device type and the current firmware version number corresponding to the device type.

[0038] Through the scheme recorded in this embodiment, the control device can obtain the type and current version number of the upgradeable device, providing a reference for subsequently providing firmware upgrade data to the upgradeable device. If the control device obtains that the version number of a type of device recorded in the firmware upgrade data is smaller than the version number of the device of the same type recorded in itself, the control device can choose to ignore the obtained firmware upgrade data.

[0039] In another exemplary embodiment, when the control device communicates with the control group wirelessly, the method further includes: Before the control device sends the firmware upgrade data to at least one upgradeable device in the device group, any upgradeable device broadcasts its own device type and current firmware version number through the industrial field bus, and saves the received device type and the current firmware version number corresponding to the device type through the industrial field bus; if there are 3 upgradeable devices in the device group, each upgradeable device broadcasts its own device type and current firmware version number through the industrial field bus, then each upgradeable device can receive and save the device type and current firmware version number of the other 2 upgradeable devices; Under the condition that the preset conditions are met, any of the upgradeable devices sends the saved device type and the current firmware version number corresponding to the device type to the control device by wireless means; the preset conditions include: each time the upgradeable device establishes a link with the control device, or one or more of the following: each time the upgradeable device establishes a link with the control device, or each time the upgradeable device establishes a link with the control device; The control device saves the received device type and the current firmware version number corresponding to the device type.

[0040] Through the solution described in this embodiment, the control device can also understand the current version of the firmware of the upgradeable device in the device group, which provides a reference for subsequently providing firmware upgrade data to the upgradeable device in the device group.

[0041] In an exemplary embodiment, the storing of the received device type and the current firmware version number corresponding to the device type includes: if there are multiple current firmware version numbers corresponding to the device type, storing the lowest firmware version number. For example, if the stored current firmware version number of the upgradeable device A is V10, if the received current firmware version number of the upgradeable device A is V11, the stored current firmware version number of the upgradeable device A is still V10; if the received current firmware version number of the upgradeable device A is V9, the stored current firmware version number of the upgradeable device A is replaced with V9.

[0042] By saving the type of upgradeable device and the current firmware version number corresponding to the type, a reference can be provided for the firmware upgrade of the device. This saving method can also ensure that the firmware version numbers of the same type of upgradeable devices in the device group are basically the same after the upgrade operation, thereby making the functions of the same type of devices in the device group consistent.

[0043] In combination with the above-described embodiments, specific application examples are given below.

[0045] The upgradeable device B in the device group receives the firmware upgrade data via a CAN bus or an RS485 bus; The upgradeable device B determines whether the firmware upgrade data can be used for the device; When the upgradeable device B determines that the received firmware upgrade data can be used for the device, it performs a firmware upgrade operation on the device according to the firmware upgrade data; after performing the upgrade operation; When the upgradeable device B determines that the received firmware upgrade data cannot be used for the device, the upgradeable device B discards the firmware upgrade data.
