Abstract
The utility model discloses an automatic switch system of played video and back running video at a on-vehicle display terminal, including an MCU, an audio-visual video signal unit for providing a DVD audio-visual video signal for the MCU and a back running video signal unit for providing a back running video signal to the MCU, wherein the audio-visual video signal unit and the back running video signal unit are directly connected with the MCU; and a back running signal unit for providing a back running signal at a reverse gear for the MCU; a drive unit is connected on an output end of the MCU; and another end of the drive unit is connected with an on-vehicle liquid crystal display screen. The MCU and the back running signal unit are linked via a CAN interface. The system can be automatically switched to the back running video state so as to save time and energy of a driver and improve driving security.
Description
Technical field
The utility model relates to a kind of Vehicular video automatic switchover system, especially relates to a kind of vehicle-mounted display terminal displaying video and reversing video automatic switchover system.
Background technology
Existing vehicle-mounted display terminal is in the process of normal play DVD, if chaufeur need be moveed backward by the reversing video, then generally, chaufeur need be closed the DVD broadcast earlier and be opened the reversing video again, reversing finishes, close the reversing video, opening DVD plays, and this function that is the mode of employing button or the mode that adopts touch screen operation are play, moveed backward is switched all more loaded down with trivial details to chaufeur, inconvenient operation, disperse the chaufeur attention easily, the safety that influence is driven.As Chinese patent 200920152119.5 disclosed a kind of Vehicular multifunctional controllers, comprise input interface, output interface, master cock, control button, described input interface comprises AV COBBAIF, AV video interface, camera video and power interface, external audio input interface, general supply interface, USB input interface and SD card slot; Described output interface comprises: display audio, display video and power supply and direct supply output interface; Described master cock comprises total power switch, reversing video automatic transfer switch.
The utility model content
The purpose of this utility model provides a kind of vehicle-mounted display terminal displaying video and reversing video automatic switchover system, and the existing vehicle-mounted display terminal displaying video of solution need manually be operated the problem of finishing by chaufeur with the reversing video switch.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of vehicle-mounted display terminal displaying video and reversing video automatic switchover system, comprise MCU and the audio-visual video signal unit of the audio-visual vision signal of DVD be provided and provide the reversing video signal unit of reversing vision signal that the described audio-visual video signal unit and the video signal unit of moveing backward directly are connected with MCU to MCU to MCU; Also comprise to MCU the astern signal unit that hangs astern signal when reversing gear is provided, described MCU mouth is connected with driver element, and the driver element other end connects vehicle-mounted LCDs.
Further, connect by the CAN interface between described MCU and the astern signal unit.
For when automatic switchover system breaks down, still can switch, near chaufeur, be provided with the shifter of vehicle-mounted display terminal displaying video and reversing video switch.Described shifter is the touch button that is arranged on vehicle-mounted display terminal.
The beneficial effects of the utility model: owing to be provided with vehicle-mounted display terminal displaying video and reversing video automatic switching control equipment in this system, hang up when reversing gear, the DVD broadcasting pictures that vehicle-mounted display terminal is showing is switched the reversing video immediately, chaufeur need not button or touch screen operation, can be by the reversing of reversing video safety, save the time and efforts of chaufeur, improved the safety of driving.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model automatic switchover system principle of work block diagram.
Fig. 2 is the utility model automatic switchover system workflow diagram.
The specific embodiment
Embodiment 1, as shown in Figure 1, this vehicle-mounted display terminal displaying video and reversing video automatic switchover system, comprise MCU and the audio-visual video signal unit of the audio-visual vision signal of DVD be provided and provide the reversing video signal unit of reversing vision signal that the described audio-visual video signal unit and the video signal unit of moveing backward directly are connected with MCU to MCU to MCU.This system also comprises to MCU provides the astern signal unit that hangs astern signal when reversing gear, and connects by the CAN interface between described MCU and the astern signal unit.Described MCU mouth is connected with driver element, and the driver element other end connects vehicle-mounted LCDs.
As shown in Figure 2, start initialize routine when at first beginning and broadcast video signal is normally controlled normal play on vehicle-mounted LCDs by MCU.When chaufeur extension backward gear, produce a level signal, MCU detects the reversing instruction, preserves current broadcast state, and the video frequency switching module that calls among the startup MCU realizes that the video demonstration switches to from the demonstration of reversing camera reversing video.Reversing finishes, and the backward gear return also produces a level signal, and MCU receives this signal, and control returns to original broadcast state.If MCU does not detect reversing instruction, the audio-visual video of normal play always.Be implemented in to hang and need do not use the switching that just can realize picture by switching push button when reversing gear.
Embodiment 2, for when vehicle-mounted display terminal displaying video breaks down with reversing video automatic switchover system, still can switch the safety reversing.Near chaufeur, be provided with the shifter of vehicle-mounted display terminal displaying video and reversing video switch.Described shifter is the touch button that is arranged on vehicle-mounted display terminal.All the other are with embodiment 1.
