[0066] The entertainment host is affected by the diverse user needs and numerous function modules, and there is strong coupling and dependency between the software of each function module. Compatibility and functionality issues need to be focused on in the late development and production stage. In actual vehicle production, since the inventory entertainment host is not powered on and cannot be connected to the network, it needs to be activated by the user after being assembled in the real car, and then upgraded, which takes a long time. It is a better choice to repair and upgrade the software of the entertainment host that has not been assembled through a mobile storage device (such as a U disk).

[0067] Most of the current common upgrading methods rely on manual operation. For inventory entertainment hosts, batch upgrading is mainly achieved through a special bench, which has functions such as power simulation, communication, flashing, and diagnosis, but requires manual participation in connection, confirmation, and recording. Specifically, the operator needs to copy the updated software to a U disk, go to the bench to upgrade the entertainment host, and manually confirm the status, connect the device, trigger the flashing, and verify the function. The bench upgrade also needs to connect the screen line, U disk interface line, and power harness. This method has three drawbacks: if the automatic upgrade mode of the bench is selected, the U disk is not removed in time after the upgrade is completed, and the system may misidentify and start the repeated upgrade. If the human interruption occurs during the secondary upgrade, the software copy transmitted to the entertainment host may not be properly removed, long-term occupying the storage space, affecting the normal operation of the entertainment host. If the manual trigger upgrade mode is selected, the host will wait for the upgrade dialog box to pop up after booting, wasting manpower. At the same time, the power harness plug-in requirement is relatively harsh. If the connection is not firm, it is easy to cause poor contact, resulting in upgrade interruption or failure. If the plug-in is too tight, the time consumption of the unplugging process increases, significantly reducing the overall work efficiency. Moreover, the numerous harnesses are tangled together, and multiple benches are placed on the workbench, which can easily cause short circuits during the replacement of the host, causing damage to the equipment.

[0068] The above artificial upgrading method is feasible, but has problems such as low efficiency, poor consistency, high labor cost, risk of missed upgrade or misoperation. In the context of large-scale production, a more efficient, traceable and automated software flashing solution is needed to improve production quality and response speed. In view of this problem, the upgrading tool and process are reformed, a set of portable and easy-to-use jigs is designed to realize fast upgrade to adapt to the frequent upgrade scene of entertainment software: first, the upgrading tool is reformed to upgrade multiple devices at a time. Second, reduce manual intervention, automatically record upgrade results, improve efficiency and facilitate version tracking.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0070] Embodiment one: The present application discloses a software upgrading method.

[0071] Specifically, please refer to Figure 1a The software upgrading method disclosed in the embodiment comprises the following steps:

[0072] Step 101: Connect multiple mobile storage devices and entertainment host groups on the jig.

[0073] The method of the embodiment is applied to a software upgrading jig disclosed in the present application. The jig is box-shaped, and the entertainment host can be placed in the jig when in use. The jig accurately designs multiple sets of power switches, USB interfaces, power interfaces and low voltage differential signaling (LVDS) interfaces for the entertainment host according to the mold of the entertainment host, as well as a set of high-definition multimedia interface (HDMI), universal asynchronous receiver transmitter (UART) interface, USB interface and power interface for the jig.

[0074] As an implementable solution, the interfaces of the jig can be as shown in Figure 1b Figure 1b The yellow rectangle in the upper right corner represents 8 USB interfaces for connecting 8 mobile storage devices on the jig. Figure 1b ​The left green ovals represent eight USB interfaces, and the eight green ovals correspond to the eight yellow rectangles in a one-to-one manner. The entertainment host and the tool are connected through the eight LVDS interfaces represented by the blue rectangles, the eight power switches represented by the purple rectangles are used to control the power supply of the eight entertainment hosts, and the eight power interfaces represented by the red rectangles are used to provide power for the eight entertainment hosts. In addition, the tool obtains power through the 220V power interface, and the tool and the electronic device (such as a computer) can be connected through the HDMI interface. One of the two UART interfaces is used to control the output of the HDMI interface, and the other is used to control the relay to control the power supply of the entertainment host.

[0075] In the method of the embodiment, the software to be upgraded is copied to a mobile storage device in a production environment, and the mobile storage device also stores an automatic upgrade script. After connecting multiple mobile storage devices to the tool, the software of multiple entertainment hosts can be upgraded and installed. As an implementable solution, eight mobile storage devices can be used to install software for a group of eight entertainment hosts, or less than eight entertainment hosts that do not form a group.

[0076] Step 102: controlling the tool to execute the automatic upgrade script to install the software in the entertainment host.

[0077] In the method of the embodiment, the tool can be controlled by an electronic device (such as a computer) to enter an automatic upgrade mode and execute an automatic upgrade script. As an implementable solution, the software interface on the computer for controlling the tool can be as shown in Figure 1c After connecting the entertainment host and the mobile storage device to the tool and turning on the power, the operator's name is input on the software in Figure 1c , the corresponding relay control port number is selected, the "Go" button in the lower right corner is clicked, the text on the button changes to "STOP", and the software installation of the entertainment host begins.

[0078] Step 103: obtaining the installation status of the software installed in the entertainment host.

[0079] In the method of the embodiment, after starting the software installation, the progress of the software installation of each entertainment host, the upgrade status of the entertainment host (i.e., the installation status of the software to be upgraded), and the time of the status change are all displayed in real time on the left side in the software interface shown in Figure 1c . Specifically, Figure 1cThe software shown collects the screens of 8 entertainment hosts in real time, and the screens of the entertainment hosts with serial numbers 1-4 and 5-8 are displayed in the upper right corner of the software interface in a cycle. The serial number of the entertainment host displayed in the upper right corner is highlighted on the left. When the user wants to view the screen of a certain entertainment host, click the corresponding number, and the upper right corner area switches to this column of entertainment hosts. As a realizable scheme, a preset number (such as 4) of entertainment hosts corresponding to the progress can be displayed on the first screen at the same time. The progress corresponding to the remaining entertainment hosts in the entertainment host group is displayed on the second screen at the same time. And the first screen and the second screen are alternately displayed according to the preset frequency.

[0080] In the method of the embodiment, the installation state of each installation result can be determined as installation success or installation failure. As a realizable scheme, the display interface of each entertainment host is obtained at a preset frequency, and the display interface is compared with the first picture and the second picture to obtain a comparison result. The first picture is a preset picture indicating installation success, and the second picture is a preset picture indicating installation failure. When the comparison result is that the similarity between the display interface and the first picture is greater than or equal to a preset value (such as 95%), it is determined that the entertainment host corresponding to the display interface is installed successfully. When the comparison result is that the similarity between the display interface and the second picture is greater than or equal to a preset value, it is determined that the entertainment host corresponding to the display interface is installed unsuccessfully.

[0081] As a realizable scheme, the display interface can be first cropped and compared with the first picture, and the display interface can be second cropped and compared with the second picture, so as to reduce the calculation amount during comparison. The first cropping can be cutting the title and the first row, and the second cropping can be cutting the picture at a specific coordinate in the lower right corner.

[0082] Step 104: in the case where the installation state is installation success, prompting to replace the entertainment host installed successfully.

[0083] In the method of the embodiment, when installation is successful, Figure 1c The "total number of upgrades today" in the lower left corner of the software interface will automatically increase by 1, and the "upgrade success rate" will also change accordingly when installation is successful or unsuccessful. When a certain entertainment host is installed and successful, the VIN code and version number of the entertainment host are saved to the local database, the power supply of the entertainment host is cut off, the color of the text box of the serial number of the entertainment host is changed, and the user can be prompted to replace the machine to continue installation through flashing. When all entertainment hosts are upgraded, click the "STOP" button in the lower right corner to end the upgrade, and the database is automatically saved. The user can view the status of the entertainment host upgraded today from the local database.

[0084] Step 105: in the case that the installation state is installation failure, prompting to perform reinstallation on the entertainment host with installation failure.

[0085] In the method of the embodiment, when an entertainment host fails to install, Figure 1c The software interface shown can prompt the user to perform reinstallation on the entertainment host with installation failure by changing the color of the text box of the entertainment host serial number.

[0086] The method of the embodiment installs the software to be upgraded in multiple entertainment hosts at one time through a software upgrade tool. The tool is convenient to carry and use, and can realize automatic and rapid software upgrade. Meanwhile, the installation state of each entertainment host can be obtained, prompting to replace the entertainment host with installation success or to perform reinstallation on the entertainment host with installation failure. The method of the application reduces manual intervention, saves labor cost and human error probability. The U disk does not need to be unplugged during one batch upgrade, avoiding the strict requirement of plugging and unplugging the power harness when replacing the entertainment host. Automatic, efficient, accurate and rapid software upgrade is realized, achieving the purpose of cost reduction and efficiency improvement, and being suitable for the scene of frequent software upgrade of the entertainment host.

[0087] Embodiment two: another software upgrade method is disclosed in the application, please refer to Figure 2 The method of the embodiment introduces the whole process of software upgrade.

[0088] Step 201: store the software to be upgraded and the automatic upgrade script to 8 U disks.

[0089] Step 202: connect the 8 U disks to the software upgrade tool through the interface, place the 8 entertainment hosts in the tool and connect them to the tool through the interface, and connect the computer to the tool through the interface.

[0090] Step 203: input the operator information in the software for controlling the tool on the computer, and check whether the information meets the requirements. If yes, go to step 204. If not, repeat step 203.

[0091] Step 204: operate the software interface for controlling the tool to start the automatic upgrade mode of the tool. The tool in the mode executes the automatic upgrade script to install the software to be upgraded in the 8 entertainment hosts.

[0092] Step 205: the tool collects the screen pictures of the 8 entertainment hosts in real time, displays the screen pictures with serial numbers 1-4 or 5-8 in the software interface of the computer at the same time, and cycles the display of the screen pictures with serial numbers 1-4 or 5-8 at a preset frequency.

[0093] Step 206: collect the screenshots of the screen pictures of the 8 entertainment hosts at a preset frequency.

[0094] Step 207: comparing the eight screenshots with the first picture representing installation success respectively, judging whether the similarity between the screenshots and the first picture is greater than or equal to a preset value. If yes, go to step 208. If no, go to step 209.

[0095] Step 208: powering off the entertainment host corresponding to the screenshot, prompting that the entertainment host is installed successfully, the entertainment host needs to be replaced, and recording installation success information.

[0096] Step 209: comparing the eight screenshots with the second picture representing installation failure respectively, judging whether the similarity between the screenshots and the second picture is greater than or equal to a preset value. If yes, go to step 210. If no, return to step 206.

[0097] Step 210: prompting that the screenshot corresponding to the entertainment host fails to install, the entertainment host needs to be replaced, and recording installation failure information.

[0120] Based on the above-mentioned software upgrading method, the application also discloses a software upgrading tool for realizing the above-mentioned method, which comprises a power conversion and distribution module, a video signal switching and collecting module and a mobile storage device interface expansion module.

[0121] The power conversion and distribution module is connected with multiple entertainment hosts through multiple interfaces and controls the power supply of each entertainment host through multiple channel relays.

[0122] The video signal switching and collecting module displays the installation state of the entertainment hosts in which the software to be upgraded is installed through a multi-channel video splitter.

[0123] The mobile storage device interface expansion module integrates multiple interfaces and provides an access channel for the mobile storage device.

[0124] In the tool of the embodiment, as an implementable scheme, the internal hardware of the tool can be as shown in the figure. Figure 3b The power conversion and distribution module provides independent and controllable DC power supply for eight entertainment hosts, and specifically, an industrial power adapter is used to convert 220V AC power supply into 12V DC power supply efficiently. The rated output of the adapter is 12V / 50A, and the total power is up to 600W, which provides sufficient power margin (calculated according to the no-load current of a single entertainment host ≤0.9A) for eight channels. The converted 12V power supply is connected to an 8-channel single-pole double-throw relay module. Each relay (one channel) independently controls the on-off of one power supply, and is connected to the corresponding entertainment host through the interface of the tool, thereby realizing the software-based accurate management of the power supply of each entertainment host.

[0125] Correspondingly, the video signal switching and collecting module expands the single computer display output into eight channels and realizes flexible gating and observation of the display pictures of each entertainment host. Specifically, an 8-in-8-out high-definition video splitter (such as an HDMI or DP splitter) is used as the signal expansion core. The tool of the embodiment communicates with the computer through a serial port (RS232 / RS485) or a USB interface. Eight LVDS signals are connected to eight LVDS-to-HDMI modules respectively, and the converted eight HDMI signals are input to an 8-in-8-out HDMI timing matrix switch. The computer sends instructions through the serial port or the USB port to select the read channel, and reads four channels at a time, thereby outputting the video signals of the entertainment hosts to the PC. The operator can simultaneously see the screens of four entertainment hosts on the computer software and monitor the real-time pictures of any host in time.

[0126] Correspondingly, the mobile storage device interface expansion module provides a dedicated and isolated mobile storage device (such as a U disk) access channel for each entertainment host. Specifically, eight LVDS-USB interface lines can be integrated inside the jig of the embodiment, with the LVDS end connected to the entertainment host and the USB end connected to the U disk. Before the entertainment host is upgraded, the U disk is inserted into the corresponding numbered interface on the jig. The interface forms a point-to-point connection with the entertainment host, effectively avoiding data conflicts and interference that may be caused by multiple entertainment hosts simultaneously accessing a single U disk, and ensuring the reliability and consistency of the upgrade process.

[0127] As an implementable solution, the entire use process of the jig of the embodiment is as follows: the software to be upgraded is stored in eight U disks according to the automatic upgrade script, and the U disks need to be mobile storage devices that can be recognized by the entertainment host. The U disks are inserted into the U disk interfaces on the jig, and the eight entertainment hosts are placed in the jig and connected in alignment. The UART and HDMI interfaces on the jig are connected to a computer, the software for controlling the jig on the computer is opened, the upgrade version, operator information, port number and other contents are confirmed, the power switch of the entertainment host on the jig is operated, and each entertainment host is powered on. Subsequently, the installation is started on the software interface for controlling the jig, and the installation status is observed. When a certain entertainment host is prompted that the installation is successful, the entertainment host is removed, and a new entertainment host to be upgraded is placed in the empty position in the jig. Correspondingly, when a certain entertainment host is prompted that the installation fails, the entertainment host is removed and marked as a failure, and a new entertainment host to be upgraded is placed in the empty position in the jig. After all the entertainment hosts are installed, the installation is ended on the software interface for controlling the jig, and an installation result table is output, and the installation is ended.

[0128] One jig in the embodiment can be operated by one person and supports simultaneous upgrade of eight racks. Only one set of jig, U disk and computer is needed during upgrade, without the need to carry additional tools, saving manpower and being easy to operate, thereby reducing costs and increasing efficiency for enterprises.
