Description
Technical field
The utility model relates to vehicle-mounted control field, especially a kind of vehicle-mounted control plate.
Background technique
Currently, touch screen control plate in the market is broadly divided into two classes, one kind is industrial single-chip microcontroller, and dominant frequency generally exists
200Mhz, can be extremely low with power consumption hereinafter, inside is the characteristics of not having MMU controller, industrial single-chip microcontroller, but cannot connect high-resolution
Screen, only up to reach 1024*768, arithmetic speed is slow, is not suitable for use in the liquid crystal instrument of graph and image processing, audio-visual amusement
Etc. projects.Another kind of is the touch control equipment based on Android system, this equipment due to the starting of Android system it is slow, be not
Real-time system, so security performance is very poor.
Summary of the invention
The utility model aim is to provide a kind of high safety, high reliablity, real-time good vehicle-mounted liquid crystal instrument control
Making sheet.
To achieve the above object, use following technical scheme: the utility model mainly includes power module, bottom plate, core
Core, touch screen driving plate and touch LCD panel module；The power module is connected with bottom plate, bottom plate respectively with core board,
Touch screen driving plate, touch LCD panel module are connected；Core board output end is connected with touch screen driving plate, and touch screen driving plate is defeated
Outlet is connected with touch LCD panel module.
Further, the bottom plate includes DC/DC module, MCU processing module, CAN communication module and constant current source module.
Further, built-in in the soleplate MCU single-chip microcontroller, MCU single-chip microcontroller are connected progress with dc/dc module, CAN chip
Communication and data processing, and data are transmitted to core board by serial ports.
Further, the core board includes IMX6Q master chip, memory modules, emmc module, spi module, flash mould
Block.
Further, the touch screen driving plate and core board are attached by USB interface, and touch screen driving plate is used for
Drive touch LCD panel module.
Further, the touch LCD panel module is connected by TTL, Lvds interface with bottom plate.
Compared with prior art, the utility model has the advantages that
1, high safety, real-time is good, high reliablity, and graph and image processing is powerful.
2, the operating system of product is QNX6.6, Microkernel is used, so that the real-time of system, security reliability
It is more outstanding.IMX6Q master chip, there is powerful figure, and image processing function can carry out 3D processing and the audio-visual amusement of progress etc.
High performance operation.
3, all mal-conditions are adapted to substantially, as long as guaranteeing to work normally, all in -30 to 80 degree of dry environment
It is optimum state.
4, scalability is good, can external multiple interfaces screen, peripheral hardware excuse is abundant, and can cut out according to the actual situation
It cuts.8 layers of pcb design of core board, 4 layers of pcb design of bottom plate, have good heat dissipation and stability.
Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model.
Fig. 2 is that the utility model insole board with core board connect expander graphs.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, 2, the utility model mainly includes power module, bottom plate, core board, touch screen driving plate and touching
Liquid crystal screen module is touched, the power module is connected by dc/dc module with bottom plate, the 12V that dc/dc module exports power module
Voltage is converted into 5V voltage input to bottom plate；Built-in MCU single-chip microcontroller in the soleplate, MCU single-chip microcontroller and dc/dc module, CAN chip
It is connected and carries out communication and data processing, and data is transmitted to core board by serial ports.The core board includes IMX6Q main core
Piece, memory modules, emmc module, spi module, flash module.The touch screen driving plate and core board by USB interface into
Row connection, touch screen driving plate is for driving touch LCD panel module.The touch LCD panel module passes through TTL, Lvds interface
It is connected with bottom plate.
The workflow of the utility model approximately as:
External 12V working power, first passes through TPS5430(dc/dc), the voltage of 5v is exported to bottom plate and core board, and mcu is negative
Duty power management and sending and receiving CAN bus data are communicated with main control chip IMX6.IMX6Q mainly handles graph image, and
Screen output, periphery peripheral hardware driven management etc..Touch screen driving plate with core board is connected by usb, for driving touch screen,
Liquid crystal display is connected with TTL, lvds interface of bottom plate.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
