[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the present application in combination with specific embodiments and with reference to the drawings.

[0029] It should be noted that, unless otherwise defined, technical terms or scientific terms used in the embodiments of the present application should be understood as the common meaning understood by a person with ordinary skills in the art to which the present application belongs. The terms "first", "second" and similar words used in the present application do not represent any order, number or importance, but are only used to distinguish different components. The terms "include" or "contain" and similar words mean that the elements or objects before the word cover the elements or objects listed after the word and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] As described in the background above, the touch screen of the vehicle-mounted control system in the related art is controlled by directly operating the screen through video monitoring software or using a separate control keyboard. For different vehicle-mounted control systems, especially for vehicle-mounted control systems applied to large road maintenance machinery video auxiliary systems and vehicle-mounted video monitoring systems, the video monitoring software may not be adapted to different vehicle-mounted control systems, and the operation may be inconvenient due to too small operation icons. Therefore, a control keyboard is separately added in most cases, especially for large road maintenance machinery, the operation platform has limited space, and the control keyboard occupies a large amount of space, increasing the difficulty of construction.

[0031] In addition, in the related art, the vehicle-mounted touch screen does not have a power soft protection function. Due to the particularity of the working environment, or due to operation habits or improper operation, the host of the vehicle-mounted system may be directly powered off. Since the smart device usually has a read-write hard disk, an SSD disk, an SD card or a NAND FLASH, an EMMC memory, accidental power failure may cause data loss, and in severe cases, the vehicle-mounted control system may not be able to complete the boot operation due to the disorder of the data of a certain key data sector of the system code, or the system may not start normally or may crash and report errors after starting.

[0032] Finally, for the application scenario of the vehicle-mounted control system, different sensors need to be connected to receive transmission signals of different sensors. Since the signal format of the sensor is different from the display format of the touch screen, the compatibility of the vehicle-mounted control system is low, and sensors that are adapted to the display format of the touch screen must be selected for signal acquisition, resulting in an increase in the cost of the vehicle-mounted control system.

[0033] Based on this, the utility model discloses a vehicle-mounted touch screen control system, comprising: host computer 1 is used to provide power supply, and receives the transmission signal of different sensor, signal converter 2 is connected with host computer 1, is used to convert the analog signal in transmission signal into digital signal, second power module 3 is connected with host computer 1 and signal converter 2 respectively, is used to receive the power -off signal of host computer 1, and provides spare power supply to signal converter 2, touch screen control module 4 is connected with host computer 1, signal converter 2 and second power respectively, is used to receive the transmission signal of host computer 1 and digital signal of digital converter, and generates corresponding user operation interface and the control button of adapting user operation interface according to transmission signal and digital signal, touch display 5 is connected with touch screen control module 4, is used to show user operation interface and control button.

[0034] In the embodiment, signal converter 2, second power module 3 and touch screen control module 4 are integrated into the vehicle-mounted touch screen control system, the analog signal in transmission signal is converted into digital signal by signal converter 2, so that the display format of transmission signal in different sensors is adapted to the format of touch display 5, effective display is realized, the compatibility of the vehicle-mounted touch screen control system is improved, and the incompatibility of old sensor signals with the vehicle-mounted touch screen control system is avoided.The second power module 3 provides spare power supply for signal converter 2 and touch screen control module 4, in the case that host computer 1 is powered off due to various reasons, such as improper operation or the use habit of the operator, the second power module 3 provides a "soft shutdown power module" with power-off current continuation function for signal converter 2 and touch screen control module 4, avoids the data loss caused by accidental power-off of the built-in SSD disk, SD card or NAND FLASH, EMMC and other memories of signal converter 2 and touch screen control module 4 in the process of signal conversion and generation of user operation interface, or the data disorder of a certain key data sector of the system code, and the vehicle-mounted touch screen control system cannot complete the boot operation, or the system cannot be normally started or crashes after starting and reports errors. Finally, the touch screen control module replaces the original physical button, saves the space occupation of the locomotive operation platform, and provides reasonable touch control buttons for the touch display 5 by using the control buttons adapted to the user operation interface, avoiding the small buttons in the related art due to the inadaptation of the touch display 5 of the vehicle-mounted touch control system in the related software.

[0035] In some embodiments, the signal converter 2 is used to convert the CVBS signal into the HDMI signal.

[0036] In some optional embodiments, as Figure 4As shown, signal converter 2 uses the MS1858E. The MS1858E includes an analog signal input terminal 21, an analog audio input / output terminal 22, a 27MHz crystal input / output terminal 23, a digital signal output terminal 24, a CVBS signal input control terminal 25, and an internal master / slave control mode configuration terminal 26. The MS1858E converts analog CVBS signals and S-Video signals to HDMI signals. The MS1858E is a single-chip device that integrates a 9-bit video analog-to-digital converter, a 24-bit audio converter, and an HDMI 1.3 version transmitter, supporting video scaling, frame rate conversion, and interlaced / progressive conversion. It is widely used in security monitoring, vehicle video, industrial control, and other fields.

[0037] It should be noted that the purpose of signal converter 2 is to provide greater compatibility, converting analog signals from sensors into digital signals. Not all sensors transmit analog signals; some may also transmit digital signals. The role of signal converter 2 is simply to convert analog signals into digital signals. Signals that are already digital can bypass signal converter 2 and be directly transmitted to the touchscreen control module.

[0038] In some embodiments, reference Figure 1 , Figure 3 As shown, the second power module 3 includes a power switching module 31 and an energy storage battery 32. The output terminal of the power switching module 31 is connected to the signal converter 2 and the touch screen control module 4, respectively. A charging circuit 33 is provided between the host 1 and the input terminal of the energy storage battery 32, and a discharging circuit 34 is connected to the output terminal of the energy storage battery 32. When the host 1 is powered on, the input terminal of the power switching module 31 is connected to the charging circuit 33. When the host 1 is powered off, the input terminal of the power switching module 31 is connected to the discharging circuit 34.

[0039] In this embodiment, the second power module 3 provides a "soft shutdown power module" with a power-off continuity function to the signal converter 2 and the touch screen control module 4 in the event of a sudden power failure of the host 1, thereby avoiding data loss or even failure to start normally due to direct power failure of the signal converter 2 and the touch screen control module 4 during operation.

[0040] In some embodiments, the power switching module 31 is a relay. A charging circuit 33 is connected between the energy storage battery 32 and the host 1, and the input of the power switching module 31 is also connected with the charging circuit 33. The host 1 charges the energy storage battery 32 and provides power for the touch screen control module 4 and the signal converter 2. In the case of power failure of the host 1, the power switching module 31 is connected with the discharging circuit 34, and the energy storage battery 32 continues to provide power for the touch screen control module 4 and the signal converter 2, avoiding the data loss or even the situation that the touch screen control module 4 and the signal converter 2 cannot start normally caused by direct power failure.

[0041] In some optional embodiments, the second power module 3 can be an UPS (Unnterruptible Power Supply).

[0042] In some embodiments, a first DC voltage reducer 35 is connected between the power switching module 31 and the host 1.

[0043] In some optional embodiments, as shown in FIG. 2, the first DC voltage reducer 35 reduces the 24V DC voltage to 12V DC voltage. Figure 3

[0044] The rated voltage of different devices or modules is different. For example, the rated voltage of the host 1 is 24V, and the rated working voltage of the signal converter 2 and the touch screen control module 4 is 12V. Through the first DC voltage reducer 35, the power supply to the signal converter 2 and the touch screen control module 4 is met, and the power failure protection of the signal converter 2 and the touch screen control module 4 is met.

[0045] In some exemplary embodiments, the first DC voltage reducer 35 can be a voltage reducer, a DC-DC converter, a linear voltage reducer, or a vehicle-mounted DC voltage reducer, etc.

[0046] In some embodiments, an alarm (not shown in the figure) is arranged between the power switching module 31 and the energy storage battery 32. The power switching module 31 is connected with the discharging circuit 34, and the alarm sends a power failure alarm signal to the touch screen control module 4 and the signal converter 2.

[0047] In the case that the discharging circuit 34 is connected, that is, the signal converter 2 and the touch screen control module 4 use the second power module 3 as a backup power supply, the alarm sends a power failure alarm signal to the signal converter 2 and the touch screen control module 4. The signal converter 2 and the touch screen control module 4 store data according to the power failure alarm signal, otherwise the signal converter 2 and the touch screen control module 4 do not know that the host 1 is powered off in the case that the second power module 3 continues to supply power.

[0048] ​In some exemplary embodiments, the alarm can be any alarm that sends an alarm signal, which is not specifically limited here.

[0049] In some embodiments, the touch screen control module 4 adopts an RK3586 mainboard, and an Ubuntu system is built-in the operating system.

[0050] In some exemplary embodiments, the RK3586 mainboard is built-in an Ubuntu system, and the Ubuntu system provides powerful command line tools and graphical user interfaces for managing file systems, installing software, configuring systems, and managing user interfaces, etc. The Ubuntu system is a desktop application-based operating system, which provides an intuitive and friendly graphical user interface, i.e., a user operation interface, to facilitate the control keys for displaying and controlling the user operation interface by the touch display in the embodiments of the application. The traditional physical keys are replaced, the operation table space is reduced, and the touch screen keys are larger and more reasonable in layout compared with the related art.

[0051] In some embodiments, a second DC voltage reducer is arranged between the touch screen control module 4 and the touch screen display.

[0052] The rated working voltages of different touch screen displays are not the same, and generally, the rated working voltage of the touch screen display is lower than that of the touch screen control module 4. Therefore, the second DC voltage reducer is arranged between the touch screen display and the touch screen control module 4.

[0053] In some exemplary embodiments, the second DC voltage reducer can be the same type of reducer as the first DC voltage reducer 35.

[0054] For example, the second DC voltage reducer reduces the DC voltage from 12V to 5V.

[0055] In some embodiments, a plurality of indicator lights 11 are arranged on the host 1 and connected between the host 1 and the signal converter 2, the second power module 3, and the touch screen control module 4, respectively, to display the working states of the signal converter 2, the second power module 3, and the touch screen control module 4.

[0056] In some exemplary embodiments, the indicator lights 11 are lit to indicate that the signal converter 2, the second power module 3, and the touch screen control module 4 are working. The indicator light 11 connected with the second power module 3 is not lit, indicating that the second power module 3 is in the working charging circuit 33 and the non-working discharging circuit 34. The indicator light 11 connected with the signal converter 2 is not lit, indicating that there is no analog signal in the current transmission signal, and the signal converter 2 is not needed to perform signal conversion.

[0057] In some embodiments, reference is made to Figure 2As shown, the sensor includes an axle temperature sensor 12 for transmitting axle temperature data to the touch screen display, a camera 13 for transmitting video data to the touch screen display, and a built-in controller 14 of the host 1 for displaying control buttons to the touch screen display.

[0058] It can be understood that, no matter the axle temperature sensor 12, the camera 13, or the built-in controller 14 of the host 1, they all display corresponding data to the touch screen display through the touch screen control module 4, and the touch screen control module 4 displays corresponding data and control buttons of the axle temperature sensor 12, the camera 13, and the built-in controller 14 on the touch screen display, so that the operator can perform corresponding control operations according to the corresponding data.

[0059] In some embodiments, the present application provides a vehicle comprising the vehicle touch screen control system of any of the above embodiments, and the vehicle includes but is not limited to large road maintenance machinery, freight cars, passenger cars, and family cars.

[0060] It should be understood by those skilled in the art that the above discussion of any of the embodiments is only exemplary and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples; the above embodiments or technical features in different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in detail for the sake of brevity.
