[0019] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

Similarly, the phrases "if it is determined" or "if it is controlled to" can be interpreted as meaning "once it is determined" or "in response to determining" or "once it is controlled to" or "in response to being controlled to" depending on the context.

[0023] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0024] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0025] As the level of intelligence increases, more and more smart devices appear in our lives, such as smart lamps, smart speakers, smart appliances, etc. Since these smart devices come from different manufacturers, they may use different protocols, which makes it difficult for users to use them and they need to download different apps to use them.

[0026] Based on the technical problems existing in the prior art, an embodiment of the present application provides a data conversion device, including: a main control unit 22, and an interface unit 21 and a communication unit 23 connected to the main control unit 22.

[0027] One end of the interface unit 21 is connected to the main control unit 22, and the other end is used to connect to the electrical device 10. After the interface unit 21 is connected to the electrical device 10, the interface unit 21 can forward the data exchanged between the electrical device 10 and the main control unit 22. The external device includes a server 31 and a user terminal device 32.

[0028] The main control unit 22 is connected to the interface unit 21 and the communication unit 23 at the same time, and can establish a communication connection with an external device through the communication unit 23 .

[0029] When the interface unit 21 is connected to the electrical device 10 for the first time, the interface unit 21 generates a connection information, which is sent to the server 31 after passing through the main control unit 22 and the communication unit 23. The server 31 will send the connection information to the user terminal device 32. The user terminal device 32 of the user is equipped with an APP. When the user terminal device 32 receives the connection information, it can find the connected electrical device 10 in the APP. The user can set the attribute information of the electrical device 10 on the APP, wherein the attribute information at least includes the manufacturer information of the manufacturer of the electrical device 10. The attribute information set by the user will be sent to the server 31 through the APP. The server 31 sends the attribute information to the conversion device according to the connection information, and the attribute information set by the user can be associated with the electrical device 10 through the connection information.

[0030] Next, the server 31 will send the attribute information to the main control unit 22 through the communication unit 23 of the conversion device. After receiving the attribute information, the main control unit 22 will determine the conversion protocol for data conversion of the electrical device 10 according to the attribute information, and notify the interface unit 21 of the conversion protocol, so that the interface unit 21 can use the conversion protocol to convert the data that the electrical device 10 needs to send into the data of the asynchronous receiver-transmitter serial port protocol (UART serial port communication protocol). At the same time, the interface unit 21 can also convert the data sent by the main control unit 22 to the electrical device 10 into data in a protocol format that matches the electrical device 10 according to the conversion protocol.

[0031] There are two conversion directions of the data conversion device in this application. One is to send the data that the electrical device 10 needs to output to the server 31 after conversion by the interface unit 21 and the main control unit 22. The other is that the user sends instructions to the electrical device 10 through the user terminal device 32 equipped with the APP or the server 31 sends data to the electrical device 10.

[0032] In the process of sending the data of the electrical device 10 to the server 31, the data output by the electrical device 10 is first converted into data of the UART serial communication protocol type by the interface unit 21 according to the conversion protocol, and the data of the UART serial communication protocol type is sent to the main control unit 22. After receiving the data of the UART serial communication protocol type, the main control unit 22 extracts key information from the data.

[0033] Since the data of the UART serial communication protocol type contains a designated flag bit, the main control unit 22 will identify the designated flag bit of the data after receiving the data of the UART serial communication protocol type, and extract the key information in the data according to the identified designated flag bit. The key data here includes: the type of the electrical device 10 and the data that the electrical device 10 needs to send out, etc.

[0034] In some embodiments, the main control unit 22 can send the extracted key data to the server 31, and then the server 31 sends it to the APP of the user terminal device 32, so as to realize real-time monitoring of the electrical device 10 through the APP. Of course, it can also be stored on the server 31, and when the user needs it, the user terminal device 32 can obtain historical data from the server 31, so that the user can easily understand the historical working status and current working status of the electrical device 10, which solves the problem in the prior art that it is difficult for users to understand the status of smart devices well because smart devices of different manufacturers use different protocols.

[0035] In the process of the user issuing instructions to the electrical device 10 through the user terminal device 32 equipped with the APP or the server 31 sending data to the electrical device 10, the user can edit instructions or other operation steps on the APP, send these edited contents to the server 31, and the server 31 sends them to the communication unit 23 of the conversion device. After receiving the data from the server 31, the communication unit 23 sends the data to the main control unit 22, and the main control unit 22 sends the data to the interface unit 21. The interface unit 21 converts the data into data of the device type of the electrical device 10 according to the conversion protocol, thereby completing the user's control of the electrical device 10 without the manufacturer's protocol, and solving the problem in the prior art that the smart devices of different manufacturers use different protocols, which makes it difficult for users to control the smart devices well.

[0036] Of course, it is also possible to preset control instructions in the server 31, and the server 31 sends data to the conversion device through the preset control instructions.

[0037] The data conversion device in the present application can be set to an independent power supply form, that is, the power consumption of the conversion device is supplied by itself, but this method will increase the size of the conversion device and there will be battery life problems. Therefore, in some embodiments, a power supply unit 24 is provided on the conversion device of the present application, and the power supply unit 24 is connected to the communication unit 23, the main control unit 22 and the interface unit 21. When the interface unit 21 is connected to the electrical device 10, the power supply unit 24 can draw power from the electrical device 10 and supply power to the main control unit 22, the interface unit 21 and the communication unit 23.

[0038] In order to allow the user to better understand whether the connection between the conversion device and the electrical device 10 and the user terminal device 32 is successful, in some embodiments, the conversion device further includes: a prompt unit 25.

[0039] The prompt unit 25 is connected to the main control unit 22, and is used to issue prompt information according to the control of the main control unit 22. The prompt information includes information that the external device is successfully connected to the electrical device 10 through the data conversion device.

[0040] When the electrical device 10 is successfully connected to the user terminal device 32 through the conversion device, the main control unit 22 controls the prompt unit 25 to send a reminder message. The prompt unit 25 can be an LED light, and the prompt message can be different light states or flashing states of the LED light. Of course, the communication unit 23 in this application can be WIFI, or it can be 5G, Bluetooth, other communication technologies of the Internet of Things, which is not limited in this application.

[0041] The data conversion device can convert data for electrical devices 10 from different manufacturers, making it convenient for users to use smart devices with different protocols and standards, and enabling devices from multiple different manufacturers to be controlled and used in a unified manner, providing users with a more convenient and intelligent smart home experience.

[0042] By using the server 31 as an intermediary to process and transmit the connection information, the user can select the manufacturer information of the connected electrical device 10 through the APP without directly operating the electronic device or electrical device 10. In this way, the usability and user experience of the system are greatly improved, and the smart home system is made more flexible and scalable.

[0043] like Figure 2 As shown, the interaction between the electrical device 10, the conversion device, the server 31 and the user terminal device 32 in this application is as follows:

[0044] When the conversion device is connected to the electrical device 10 for the first time, the conversion device will send connection information to the server 31, and the connection information will be sent to the user-end device 32 by the server 31. When the user-end device 32 receives the connection information, it can find the connected electrical device 10 through the APP on the user-end device 32, and the user can set the attribute information of the electrical device 10. The set attribute information will be sent to the server 31, and then sent to the conversion device via the server 31.

[0045] The main control unit 22 in the conversion device can determine the conversion protocol used by the interface unit 21 to implement data conversion based on the attribute information, and notify the interface unit 21 of the conversion protocol, so that the interface unit 21 can convert the data that the electrical device 10 needs to send into the serial port protocol data through the conversion protocol, and can also convert the data that needs to be input into the electrical device 10 into the data of the preset protocol of the electrical device 10.

[0046] After the configuration of the conversion device is completed, the data of the electrical device 10 can be obtained through the conversion device or the electrical device 10 can be controlled through the conversion device.

[0047] In the process of sending data from the electrical device 10, the interface unit 21 obtains the data sent by the electrical device 10, and then converts the data sent by the electrical device 10 into serial port protocol data through a conversion protocol. The main control unit 22 identifies the specified flag bit of the serial port protocol data, extracts key data from the serial port protocol data according to the specified flag bit, and sends the key data to the server 31.

[0048] When the electrical device is controlled through the conversion device, the user presets instructions or operation data in the user terminal device 32, and the instructions or operation data are sent to the server 31, and then sent to the conversion device via the server 31. The interface unit 21 in the conversion device converts the instructions or operation data into data of the preset protocol of the electrical device 10 according to the conversion protocol, and sends it to the electrical device 10 to realize the control of the electrical device.

[0049] Embodiment 2:

[0050] In view of the problems existing in the prior art, such as Figure 3 As shown, the present application provides a data conversion method, which is applied to electronic production equipment, and the electronic production equipment can be a server, a mobile terminal, a computer, a cloud platform, and a conversion device. The function implemented by the production equipment data processing provided in the embodiment of the present application can be implemented by calling a program code by a processor of the electronic production equipment, wherein the program code can be stored in a computer storage medium. The conversion method includes:

[0051] Step S1: In response to the access of an electrical device, the connection information of the electrical device is sent to an external device.

[0052] In some embodiments, step S1 “sending the connection information of the electrical device to an external device” includes:

[0053] Step S11: sending the connection information of the electrical device to a server, so that the server forwards it to a user terminal device, so that the user can select the attribute information of the electrical device through the connection information of the electrical device prompted by the user terminal device.

[0054] When the interface unit is connected to the electrical device for the first time, the interface unit generates a connection information, which is sent to the server through the main control unit and the communication unit. The user's client device is equipped with an APP, and the user can set the attribute information of the electrical device on the APP, where the attribute information at least includes the manufacturer of the electrical device. The attribute information set by the user will be sent to the server through the APP. Since there is connection information generated by the conversion device at this time, the attribute information set by the user can be associated with the electrical device through the connection information.

[0055] Step S2: receiving the attribute information of the electrical device fed back by the external device, wherein the attribute information of the electrical device is determined according to the connection information of the electrical device.

[0056] In some embodiments, step S2 of “receiving attribute information of the electrical device fed back by the external device” includes:

[0057] Step S21: receiving the attribute information of the electrical device forwarded by the server, wherein the attribute information of the electrical device is fed back by the user terminal device.

[0058] Step S3: Determine the data protocol applied by the electrical device based on the attribute information of the electrical device.

[0059] The server will send the attribute information to the main control unit through the communication unit of the conversion device. After receiving the attribute information, the main control unit will determine the conversion protocol for data conversion of the electrical device according to the attribute information, and notify the interface unit of the conversion protocol, so that the interface unit can use the conversion protocol to convert the data that the electrical device needs to send into the data of the asynchronous receiver-transmitter serial port protocol (UART serial port communication protocol). At the same time, the interface unit can also convert the data sent by the main control unit to the electrical device into data in a protocol format that matches the electrical device according to the conversion protocol.

[0060] Step S4: converting the data interacting with the electrical device according to the data protocol applied by the electrical device.

[0061] There are two conversion directions of the data conversion device in this application. One is to send the data that the electrical device needs to output to the server after conversion by the interface unit and the main control unit. The other is that the user sends instructions to the electrical device through the user terminal device equipped with the APP or the server sends data to the electrical device.

[0062] In some embodiments, step S4 "converting the data interacting with the electrical device according to the data protocol applied by the electrical device" includes:

[0063] Step S41: according to the data protocol used by the electrical device, convert the instruction sent by the main control unit into an instruction recognizable by the electrical device, wherein the instruction sent by the main control unit includes the control instruction sent by the external device.

[0064] Step S42: Sending a command recognizable by the electrical device to the electrical device.

[0065] When a user issues instructions to an electrical device through a user-end device equipped with an APP or a server sends data to an electrical device, the user can edit instructions or other operating steps on the APP, send these edited contents to the server, and the server sends them to the communication unit of the conversion device. After receiving the data from the server, the communication unit sends the data to the main control unit, and the main control unit sends the data to the interface unit. The interface unit converts the data into data of the device type of the electrical device according to the conversion protocol, thereby completing the user's control of the electrical device without going through the manufacturer's protocol. This solves the problem in the prior art that it is difficult for users to control smart devices well because smart devices from different manufacturers use different protocols.

[0066] Of course, it is also possible to preset control instructions in the server, and the server sends data to the conversion device through the preset control instructions.

[0067] In some embodiments, step S4 "converting the data interacting with the electrical device according to the data protocol applied by the electrical device" further includes:

[0068] Step S43: According to the data protocol applied by the electrical device, the data received from the electrical device is converted into data recognizable by the main control unit, and sent to the main control unit.

[0069] Step S44: the main control unit extracts data of a designated flag bit from the received data based on the attribute information of the electrical device, and determines the type and state of the electrical device according to the data of the designated flag bit.

[0070] In the process of sending the data of the electrical device to the server, the data output by the electrical device is first converted into UART serial communication protocol type data by the interface unit according to the conversion protocol, and the UART serial communication protocol type data is sent to the main control unit. After receiving the UART serial communication protocol type data, the main control unit will extract key information from the data.

[0071] Since the data of the UART serial communication protocol type contains designated flag bits, the main control unit will identify the designated flag bits of the data after receiving the data of the UART serial communication protocol type, and extract the key information in the data according to the identified special standard bits. The key data here include: the type of electrical equipment and the data that the electrical equipment needs to send out, etc.

[0072] In some embodiments, the main control unit can send the extracted key data to the server, which is then sent to the APP of the user terminal device, so that the real-time monitoring of the electrical equipment can be realized through the APP. Of course, it can also be stored on the server. When the user needs it, the historical data can be obtained from the server through the user terminal device, so that the user can easily understand the historical working status and current working status of the electrical equipment, which solves the problem in the prior art that it is difficult for users to understand the status of smart devices well because smart devices from different manufacturers use different protocols.

[0073] In order to allow the user to better understand whether the connection between the conversion device and the electrical device and the user-end device is successful, in some embodiments, the method further includes the steps of:

[0074] Step S5: outputting prompt information when receiving the attribute information of the electrical device, wherein the prompt information includes information that the external device is successfully connected to the electrical device through the data conversion device.

[0075] When the electrical device is successfully connected to the user-end device through the conversion device, the main control unit will control the prompt unit to send a reminder message. The prompt unit can be an LED light, and the prompt message can be different light states or flashing states of the LED light. Of course, the communication unit in this application can be WIFI, or 5G, other communication technologies of the Internet of Things, which are not limited in this application.

[0076] The data conversion method can convert data between electrical devices from different manufacturers, making it convenient for users to use smart devices with different protocols and standards, and enables devices from multiple different manufacturers to be uniformly controlled and used, providing users with a more convenient and intelligent smart home experience.
