Background technology
In the special applications such as medical imaging, industry, a computer system is frequently necessary to connect more display terminals.This
A little display terminals are likely to be same model or different model, it is sometimes desirable to which all display terminals show same frame, need sometimes
Show different pictures.And existing DP signal distributors are typically only capable to meet one of which functional requirement, cannot be satisfied a variety of work(
It can demand.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of DisplayPort signals with configurable functionality
Distribution system realizes 1 to, 4 distributor functions using 3 DP distributor chip cascades, you can to connect 4 displays simultaneously
Device；Solves the different terminals display problem of a computer different pictures.
The utility model technical solution used for the above purpose is：
A kind of DisplayPort signal distribution systems with configurable functionality, including computer, DP distributors, MCU；
Wherein
Computer connects DP distributors by DP signal input interfaces, and DP signals are sent to DP distributors, DP distributors
DP signal output interfaces be separately connected four displays, DP signals are divided into four road signals, are separately sent to four displays；
MCU connects computer by USB interface, and MCU passes through I2C buses are connect with DP distributors, switching switch connection
MCU controls DP distributor operating modes.
The DP distributors include the first DP distributors, the 2nd DP distributors and the 3rd DP distributors；Wherein the first DP points
Orchestration by its DP signal input interface connect computer, by its DP signal output interface be separately connected the 2nd DP distributors and
3rd DP distributors；The DP signal input interfaces of 2nd DP distributors and the 3rd DP distributors are separately connected two displays, often
Platform display receives DP signals all the way.
Further include DC power supply translation circuit, electric power output voltage is converted into operating voltage needed for system.
The utility model has the advantages that and advantage：
The utility model has unusual wide-range power input voltage ability (DC 10V-30V), can be applicable in and different is
System environment, can extend multiple displays, and complete digital signal ensures the accuracy of multi-media signal.Can by USB interface or
Allocation model is configured to single data stream transmission mode (SST patterns) or multiple data stream transmission mode (MST) by switching switch, can be matched
Setting property makes using more flexible.
Description of the drawings
Fig. 1 is the system construction drawing of the utility model.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
It is the system construction drawing of the utility model as shown in Figure 1.
System includes computer and display.The computer is by DP distributors, the DP multimedias that computer is exported
Signal is sent on 4 displays.DP distributors connect computer DP interfaces by input interface, and 1 road DP signals are assigned as 4
Road DP signals, output interface are connected respectively to 4 displays.
The DP distributors include DP signals distribution chip, microcontroller (MCU) and DC power supply translation circuit (DC/
DC)；Wherein, DP signals distribution chip connection DP signal input ports and output port, realize the distribution function of DP signals；
Microcontroller distributes chip with DP signals by iic bus and connect, while microcontroller is connected by USB and computer
It connects or by I/O interfaces and switching switch connection.According to computer or switching switch setting, the work of DP signal distributors is controlled
Pattern (SST/MST)；
Power input voltage is converted to the operating voltage needed for DP other circuits by DC power supply translation circuit.
The DC power supply translation circuit of the DP distributors has wide scope input supply voltage ability.
Multi-media signal distribution system hardware is divided into 3 parts：It is DP distributors (Chip1-3), microcontroller (MCU), straight
Flow power converting circuit (DC/DC).
DP dispenser portions：It is cascaded using the STDP4320 chips of 3 MegaChips companies, realizes 1 to's 4
DP signal distribution functions.
Microcontroller part：Using the C8051F340 chips of Silicon Laboratories companies, as pattern configurations
Controller.Its iic bus interface is connect with the main new chip STDP4320 of DP distributors respectively, by configuration information write-in DP distribution
Device master chip.
Its I/O interface is connect with switching switch connection, USB interface with computer, realizes two kinds of user configuration sides respectively
Formula.
DC power supply translation circuit part：Using the RT8279 chips of RICHTEK companies, it is responsible for turning power input voltage
It is changed to the operating voltage needed for DP other circuits, and there is very wide power input voltage ability.
