[0034] Before introducing the OTA upgrading device, electronic equipment and OTA upgrading system of the present application, first introduce the related background information of the embodiments of the present application.

[0035] For NO-OS chip or electronic equipment (such as TV, pure display device, etc.) with NO-OS chip, since NO-OS chip cannot be OTA upgraded without operating system, it is necessary to ensure the stability of the related software program when production is completed. Once the software appears abnormal running or cannot normally run due to lower version, it is necessary to send engineers to the site to copy and upgrade the program by U disk, resulting in higher maintenance cost.

[0036] Based on this, the embodiments of the present application provide an OTA upgrading device, electronic equipment and OTA upgrading system. When the remote upgrading module is not configured with storage function, the first transmission path between the storage module and the remote upgrading module and the second transmission path between the storage module and the NO-OS chip to be upgraded are selected by the path switching module, so that the upgrading program is transmitted from the remote upgrading module to the storage module, and then transmitted from the storage to the NO-OS chip to be upgraded. When the remote upgrading module is configured with storage function, the remote upgrading module directly sends the obtained upgrading program to the NO-OS chip to be upgraded through the second transmission path. Thus, the OTA upgrading of the NO-OS chip to be upgraded is realized, the maintenance cost is reduced, the user experience is optimized, and the application range of the NO-OS chip is expanded.

[0037] The OTA upgrading device, electronic equipment and OTA upgrading system provided by the present application will be described in detail below.

[0038] First, the present application provides an OTA upgrading device, please refer to Figure 1 , Figure 1 is a module schematic diagram of the OTA upgrading device provided in the embodiments of the present application. The OTA upgrading device 100 includes a path switching module 110 and a NO-OS chip to be upgraded 120 connected in communication. The path switching module 110 and the NO-OS chip to be upgraded 120 can be used to connect the remote upgrading module 200 respectively.

[0039] When the remote upgrading module 200 is not configured with storage function, the OTA upgrading device 100 further includes a storage module 130.

[0040] The path switching module 110 is connected with the storage module 130, the remote upgrading module 200 and the NO-OS chip to be upgraded 120 respectively, so as to select the path between the first transmission path C1 between the storage module 130 and the remote upgrading module 200 and the second transmission path C2 between the storage module 130 and the NO-OS chip to be upgraded 120.

[0041] The remote upgrade module 200 can be configured to send the obtained upgrade program to the storage module 130 when the channel switching module 110 selects the first transmission channel C1, and send an upgrade instruction to the NO-OS chip 120 to be upgraded when the channel switching module 110 selects the second transmission channel C2, so that the NO-OS chip 120 to be upgraded obtains the upgrade program in the storage module 130 based on the second transmission channel C2.

[0042] When the remote upgrade module 200 is configured with a storage function, the remote upgrade module 200 connects the NO-OS chip 120 to be upgraded based on the second transmission channel C2 to send the obtained upgrade program to the NO-OS chip 120 to be upgraded through the second transmission channel C2.

[0043] In the embodiment, the remote upgrade module 200 has a network communication function, so that the upgrade program for the NO-OS chip 120 to be upgraded can be obtained from elsewhere based on the function.

[0044] The channel switching module 110 selects the first transmission channel C1 and the second transmission channel C2, which can be understood as that when the channel switching module 110 selects the first transmission channel C1, the second transmission channel C2 is in an open circuit state, and when the channel switching module 110 selects the second transmission channel C2, the first transmission channel C1 is in an open circuit state.

[0045] That is, based on the channel switching module 110, the first transmission channel C1 and the second transmission channel C2 are selectively conducted.

[0046] In the embodiment, the storage module 130 has a storage function, so that when the channel switching module 110 selects the first transmission channel C1, the remote upgrade module 200 can transmit the obtained upgrade program to the storage module 130 for storage based on the conducted first transmission channel C1.

[0047] When the channel switching module 110 selects the second transmission channel C2, the remote upgrade module 200 can send an upgrade instruction to the NO-OS chip 120 to be upgraded, so that the NO-OS chip 120 to be upgraded can read the upgrade program stored in the storage module 130 based on the conducted second transmission channel C2 in response to the upgrade instruction, thereby realizing OTA upgrade.

[0048] When the remote upgrade module 200 has a storage function, Figure 1The storage module 130 and the remote upgrade module 200 are connected by a dashed line, which can be understood as that the storage module 130 is built in the remote upgrade module 200, or the storage module 130 and the remote upgrade module 200 are the same unit module. Since the remote upgrade module 200 itself can store the upgrade program, it is no longer necessary to transmit the upgrade program to the externally connected storage module, and therefore, the first transmission path C1 can be omitted in this embodiment, that is, the path switching module 110 can always select the second transmission path C2.

[0049] Therefore, the remote upgrade module 200 can connect the NO-OS chip 120 to be upgraded based on the second transmission path C2, so as to send the obtained upgrade program to the NO-OS chip 120 to be upgraded through the second transmission path C2, and realize OTA upgrade of the NO-OS chip 120 to be upgraded.

[0050] The OTA upgrade device 100 provided by the embodiment of the present application, when the remote upgrade module 200 is not configured with a storage function, the first transmission path C1 between the storage module 130 and the remote upgrade module 200 and the second transmission path C2 between the storage module 130 and the NO-OS chip 120 to be upgraded are selected by the path switching module 110, when the first transmission path C1 is selected, the remote upgrade module 200 sends the upgrade program to the storage module 130 for storage through the first transmission path C1, when the second transmission path C2 is selected, the NO-OS chip 120 to be upgraded obtains the upgrade program stored in the storage module 130 based on the second transmission path C2, and the OTA upgrade of the NO-OS chip 120 to be upgraded is realized; when the remote upgrade module 200 is configured with a storage function, the remote upgrade module 200 can directly send the upgrade program to the NO-OS chip 120 to be upgraded through the second transmission path C2; compared with the related art which needs engineers to upgrade on site, the maintenance cost is greatly reduced, and the user experience is optimized.

[0051] Next, the various unit modules shown in Figure 1 and the specific implementation manner that can be used in actual application will be described in detail.

[0052] As shown in Figure 2 In some embodiments of the present application, the remote upgrade module 200 is in communication connection with a remote server 300, and the remote upgrade module 200 can be specifically used for: accessing the remote server 300 in response to a trigger instruction, so as to obtain the upgrade program stored in the remote server 300.

[0053] In the embodiment of the present application, the remote server 300 can be a server device provided by the developer of the NO-OS chip 120 to be upgraded, and the remote server 300 can be an independent server, or a server network or a server cluster composed of servers.

[0054] For example, the remote server 300 described in the present application includes but is not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of a plurality of servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0055] When the engineer updates the program of the NO-OS chip in an iterative manner, the corresponding upgrade program can be uploaded to the remote server 300 for OTA upgrade download.

[0056] The remote upgrade module 200 and the remote server 300 can realize network communication through any communication mode, including but not limited to mobile communication based on the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), such as Bluetooth, WIFI, Zigbee, etc.

[0057] In the embodiment, the trigger instruction can be an instruction issued by a user, an instruction issued by the remote server 300, or an instruction issued by another functional module connected with the remote upgrade module 200.

[0058] In a specific implementation, the NO-OS chip to be upgraded 120 is carried on an interactive flat panel display (IFPD), and when the NO-OS chip to be upgraded 120 needs to be upgraded, the user can select an upgrade icon corresponding to the NO-OS chip to be upgraded 120 on the desktop menu of the IFPD, and trigger the master module / MCU of the IFPD to issue a trigger instruction to the remote upgrade module 200 by clicking the upgrade icon, so that the remote upgrade module 200 can access the remote server 300 in response to the trigger instruction and obtain the upgrade program stored in the remote server 300.

[0059] In another specific implementation, when the engineer uploads a new upgrade program to the remote server 300, the remote server 300 can also issue a trigger instruction to the remote upgrade module 200 connected therewith, or the remote server 300 can automatically issue a trigger instruction to the remote upgrade module 200 after receiving the new upgrade program, so that the remote upgrade module 200 accesses the remote server 300 in response to the trigger instruction and obtains the upgrade program.

[0060] In yet another implementation mode, the remote upgrade module 200 can be further connected with a timer, which is pre-configured with a timing duration. When the timer starts working, it can send a trigger instruction to the remote upgrade module 200 to access the remote server 300 to realize the automatic detection of the timing update, whenever the accumulated duration reaches the timing duration.

[0061] In some embodiments of the present application, the path switching module 110 can be specifically configured to: in response to a first switching instruction, the first switching instruction can be used to indicate that the remote upgrade module 200 is ready to obtain the upgrade program, the first transmission path C1 is enabled.

[0062] In the embodiment, the first switching instruction can be an instruction issued by the NO-OS chip 120 to be upgraded. For example, when the remote upgrade module 200 receives a trigger instruction and is ready to obtain the upgrade program, an instruction is issued to inform the NO-OS chip 120 to be upgraded, so as to trigger the NO-OS chip 120 to be upgraded to send a first switching instruction to the path switching module 110; or after the device is powered on, the NO-OS chip 120 to be upgraded can also automatically send a first switching instruction to the path switching module 110; in general, as long as the first switching instruction is sent to trigger the path switching module 110 to act before the remote upgrade module 200 obtains the upgrade program.

[0063] After receiving the first switching instruction, the path switching module 110 can enable the first transmission path C1 between the storage module 130 and the remote upgrade module 200, so as to prepare for the transmission and storage of the upgrade program.

[0064] In order to ensure the security of the NO-OS chip to be upgraded and avoid the chip from being attacked or maliciously tampered, in some embodiments of the present application, the remote upgrade module 200 can be specifically configured to: when the path switching module 110 enables the first transmission path C1, based on the agreed communication protocol, the identity authentication is performed with the storage module 130, and after the authentication is successful, the obtained upgrade program is sent to the storage module 130.

[0065] In the embodiment of the present application, the remote upgrade module 200 can perform identity authentication on the storage module 130 located at the other end of the first transmission path C1. It can be understood that before the communication starts, the remote upgrade module 200 and the storage module 130 can agree on the communication protocol, and the agreed content includes but is not limited to the handshake protocol, the device unique identifier, the encryption and decryption algorithm used, etc. The specific agreement can be made according to the actual application scene, which is not limited here.

[0066] For example, after the first transmission path C1 is connected, the remote upgrade module 200 can send an authentication instruction to the storage module 130, and the storage module 130 can respond to the authentication instruction by sending a reply instruction carrying its own identification code to the remote upgrade module 200. After receiving the reply instruction, the remote upgrade module 200 can extract the identification code of the storage module 130 from it and compare the extracted identification code with the stored correct identification code. If the comparison is consistent, it can be considered that the currently connected storage module 130 is a trustworthy storage module, and the upgrade program can be sent to the storage module 130 for storage through the first transmission path C1.

[0067] In some embodiments of the present application, the path switching module 110 may be specifically configured to enable the second transmission path C2 in response to a second switching instruction, where the second switching instruction may be configured to indicate that the upgrade program has been stored in the storage module 130 .

[0068] In the embodiment of the present application, the second switching instruction may be an instruction issued by the NO-OS chip 120 to be upgraded.

[0069] For example, after the remote upgrade module 200 completes sending the upgrade program, it can send an instruction indicating the completion of the sending to the NO-OS chip 120 to be upgraded. The NO-OS chip 120 to be upgraded can then respond to the instruction and send a second switching instruction to the path switching module 110. Considering that there may be a certain delay in data transmission, after the remote upgrade module 200 completes sending the upgrade program, the NO-OS chip 120 to be upgraded can also send the second switching instruction to the path switching module 110 after a certain delay.

[0070] After receiving the second switching instruction, the path switching module 110 may switch from selecting the first transmission path C1 to selecting the second transmission path C2 in response to the second switching instruction, so as to prepare for obtaining the NO-OS chip 120 to be upgraded.

[0071] like Figure 3 As shown, in some embodiments of the present application, the path switching module 110 may include a USB switch 1101, the remote upgrade module 200 and the NO-OS chip 120 to be upgraded are respectively configured with a USB interface, and the USB switch 1101 is connected to the USB interface of the remote upgrade module 200 through a first USB extender 1102, and is connected to the USB interface of the NO-OS chip 120 to be upgraded through a second USB extender 1103.

[0072] In the embodiment of the present application, the USB switch 1101 may be any existing type of USB switch. The USB switch 1101 may have at least two channels, and the first transmission path C1 and the second transmission path C2 may be switched through the USB switch 1101 .

[0073] The first USB extender 1102 and the second USB extender 1103 can be any type of existing USB hubs. One USB port can be expanded to two or more USB ports through the USB extenders.

[0074] In this embodiment, the upgrade program can be normally transmitted by connecting the first USB extender 1102 to the USB interface of the remote upgrade module 200 and the second USB extender 1103 to the USB interface of the NO-OS chip 120 to be upgraded.

[0075] In some embodiments of the present application, the remote upgrade module 200 may include a main control chip configured with a communication unit, so that the main control chip can communicate with the remote server 300 storing the upgrade program through the communication unit.

[0076] The storage module 130 may include a USB controller, a microcontroller, or a system-on-chip having a flash memory function.

[0077] It can be understood that when the storage module 130 is a microcontroller, the microcontroller may include a storage unit, so that the storage unit can be used to act as a storage module to store the upgrade program; the same is true when the storage module 130 is a system-level chip, which will not be repeated here.

[0078] like Figure 4 As shown, in some embodiments, the remote upgrade module 200 can be configured with a storage function. Figure 4 The remote upgrade module 200 and the storage module 130 are connected by a dotted line, which can be understood as the storage module 130 being built into the remote upgrade module 200. Since the remote upgrade module 200 itself can store the upgrade program, there is no need to transmit the upgrade program to the external storage module. Therefore, the first transmission path C1 can be omitted in this embodiment, that is, the USB switch 1101 can always select the second transmission path C2.

[0079] That is to say, the remote upgrade module 200 can be directly connected to the USB switch 1101 and connected to the NO-OS chip 120 to be upgraded through the second USB extender 1103. After the NO-OS chip 120 to be upgraded receives the upgrade instruction, it can also access the remote upgrade module 200 through the second transmission path C2 to obtain the upgrade program to complete the OTA upgrade.

[0080] The OTA upgrading device 100 provided in the embodiments of the present application can be applicable to PC operating systems, such as Windows system, and the like, when the remote upgrading module 200 is not configured with a storage function; and can be applicable to Android systems, such as ColorOS, and the like, when the remote upgrading module 200 is configured with a storage function. The OTA upgrading device 100 of the embodiments of the present application can be configured according to actual application scenarios, thereby widening the application range of OTA upgrading.

[0083] The electronic device 400 is provided with the OTA upgrading device 100 of the above-described embodiments, thereby having all the beneficial effects of the OTA upgrading device 100 in any of the above-described embodiments, which will not be repeated here.

[0084] On the basis of the above-described embodiments, the embodiments of the present application further provide an OTA upgrading system, which can include the remote upgrading module 200 and the OTA upgrading device 100 or the electronic device 400 described above, wherein the remote upgrading module 200 is pluggable to the OTA upgrading device 100 or the electronic device 400.

[0085] In the embodiments, the remote upgrading module 200 can be carried on an open pluggable computer or an Android box, or the like, pluggable device. It can be understood that the open pluggable computer is a computer conforming to the open pluggable specification (OPS).

[0086] The OTA upgrading device 100 or the electronic device 400 can be configured with an interface compatible with the device interface of the pluggable device described above, to realize the plugging of the two, so that when the pluggable device configured with the remote upgrading module 200 is plugged into the OTA upgrading device 100 or the electronic device 400, the OTA upgrading of the NO-OS chip in the OTA upgrading device 100 or the electronic device 400 can be realized based on the remote upgrading module 200.
