Description
Technical field
The present invention relates to automobile instrument field more particularly to liquid crystal instrument for automobile technologies.
Background technique
Currently, liquid crystal instrument and multimedia vehicle device integrated system more come with extensive use, multimedia system, while bringing instrument
Table safety problem.Therefore, it breaks down in system, when system in case of system halt, while the car is driving, instrument cannot go out
Screen is now put out, therefore can not restore normal by restarting system.
Following patent:
CN108608863A virtual instrument monitors emergency system and working method
A kind of method relevant to instrument emergency backup is proposed, but there are some problems:
1, patented method is for independent instrument system, and it is not suitable that addition virtual instrument, which monitors emergency system device,
With the multimedia integrated system of liquid crystal instrument and vehicle device；
2, the emergency backup system function started is limited, differs too much, can only be done in short-term with normal instrument function and effect
Emergency use, can not travel the long period in use；
3, the devices such as additional camera shooting are needed.
Instrument backup emergency measure, guarantee driving safety must be taken.
Summary of the invention
It is a kind of for full liquid crystal instrument and vehicle device multimedia integration collection the technical problem to be solved by the present invention is to realize
At system, provide a kind of method of liquid crystal instrument emergency display under thrashing situation, occur to realize in multimedia system therefore
Barrier starts corresponding emergency instrument display processing, meets driver and continues to drive needs.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of automobile instrument system, LVDS Switch
Module issues display signal, the received display signal of the automobile instrument display institute, the LVDS Switch mould to automobile instrument
The rgb interface of the rgb interface connection SOC module of block, the SOC module issue display signal, system to LVDS Switch module
Equipped with MCU, the MCU connection SOC module obtains the state heartbeat message of SOC module, the MCU connection LVDS Switch mould
Block, and send instrument emergency backup to LVDS Switch module and show signal, and control LVDS Switch module and SOC mould
The control signal of block on-off.
It is communicated between the MCU and SOC module by IPC
The MUC is MAC57HD chip.
The automobile instrument is liquid crystal instrument.
Control method based on the automobile instrument system:
SOC module sends display signal, the display that LVDS Switch module will acquire to LVDS Switch module in real time
Signal is sent to automobile instrument, the received display signal of automobile instrument display institute in real time；
SOC module sends state heartbeat message to MCU in real time, and when MCU can not receive the heartbeat message of SOC, then MCU is issued
Controlling signal disconnects LVDS Switch module with SOC module to LVDS Switch module, while MCU starts instrument
Emergency backup system, handles the display function of instrument, and MCU sends display signal, LVDS Switch to LVDS Switch module
The display signal of MCU is delivered to automobile instrument, the received display signal of automobile instrument display institute by module；
MCU starts in instrument emergency backup systematic procedure, if MCU is normally received the state heartbeat message of SOC module,
MCU issues control signal makes LVDS Switch module and SOC module restore to connect to LVDS Switch module, and closes MCU
Instrument emergency backup system, while SOC module restores to send display signal in real time to LVDS Switch module.
The MCU instrument emergency backup system removal automobile instrument show during interfaces transition animation effect, instrument
Table and vehicle device interaction content.
The advantage of the invention is that the liquid crystal instrument for automobile with backup emergency measure, weighs automatically when can break down again
It opens, guarantee driving safety.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is liquid crystal instrument for automobile functional block diagram.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
System is divided into two modules that can be in communication with each other of SOC and MCU, shares instrument liquid crystal by LVDS Switch
Display screen curtain, the function algorithm processing of instrument is realized in MCU under normal circumstances, and the display of instrument is SOC processing, LVDS
Switch receives the display signal of SOC, when MCU detects that SOC breaks down, and heartbeat message is not received in certain time,
MCU starts standby system, and switching LVDS Switch receives the display signal of MCU, opens instrument emergency backup function；When MCU is examined
When measuring SOC fault recovery, switching LVDS Switch receives the display signal of SOC again, and MCU closes standby system, instrument system
System restores normal.
Specifically as shown in Figure 1, system includes Jacinto 6SOC module and MAC57HD MCU module, display output all connects
It is connected on LVDS Switch, and LVDS Switch is controlled by MCU, instrument liquid crystal display screen, which receives, comes from LVDS Switch
Display signal.Between acinto 6SOC and MAC57HD MCU, software communication is done by IPC, SOC constantly sends shape to MCU
State heartbeat message.
Under normal circumstances, SOC is responsible for running multimedia vehicle system, while receiving MCU instrument message, and processing instrument is shown
Function, MCU are arranged LVDS Switch and are connected to SOC display output.
Under abnormal conditions, MCU can not receive the heartbeat message of SOC, and MCU starts instrument emergency backup system, handle instrument
Display function, and be arranged LVDS Switch disconnect SOC connection, connection MUC display export.
MAC57HD chip display performance can handle the instrument liquid crystal display screen of resolution ratio 1920x720, display effect completely
It is compared under fruit and normal display state, eliminates interfaces transition animation effect, instrument and vehicle device interaction content, remain exhausted big portion
Divide instrument function, can satisfy normal driving demand.
In MCU starting instrument emergency backup system, if SOC restores normal, MCU is normally received the state heartbeat report of SOC
Text, setting LVDS Switch disconnect MCU connection, restore connection SOC display output, and close MCU instrument emergency backup function,
System restores normal.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
