Abstract
A kind of to show and communicate specific integrated circuit plate: middle position is equipped with main control chip, the communication interface circuit being connected with the PORT COM of the main control chip, the human-computer interaction interface being connected with the PORT COM of the main control chip；The peripheral circuit of the communication interface circuit and main control chip is distributed in circuit board two sides；Circuit board is dual platen, and the one side for being provided with main control chip is known as component side, and the main circuit in face where Master control chip spreads copper, and the back side in face also spreads copper where Master control chip.The utility model is double-sided PCB structure, component is distributed in the two sides of plank, to give high-frequency digital signal one complete return flow path, and reduce the wiring of DC network, and reduce grounding wire impedance, with to EMC(Electro Magnetic Compatibility, Electro Magnetic Compatibility) play certain shielding action, therefore the positive and negative large area of circuit board spreads copper.
Description
Technical field
The utility model relates to a kind of display and communication specific integrated circuit plates, are in particular a kind of industrial soft starts
Equipment integrated circuit board.
Background technique
With the development that electronic/electrical gas technology is maked rapid progress, MCU(Microcontroller Unit, single-chip microcontroller) in electricity
More and more extensive use in son/electrical equipment, the control and communication between each electronic equipment are also more and more.Industrial electric is set
Standby first requirement is exactly operational safety, reliable, then the communication between electrical equipment is particularly important.
Utility model content
In order to solve the above technical problems, the utility model provide it is a kind of display and communication specific integrated circuit plate.
The technical solution of the utility model specifically:
It is a kind of to show and communicate specific integrated circuit plate: the main control chip of middle position to be mounted on, with the main control chip
The communication interface circuit that is connected of PORT COM, the human-computer interaction interface being connected with the PORT COM of the main control chip；
The peripheral circuit of the communication interface circuit and main control chip is distributed in circuit board two sides；Circuit board is dual platen, is provided with master
The one side of control chip is known as component side, and the main circuit in face where Master control chip spreads copper, the back side in face where Master control chip
Spread copper.
Further: human-computer interaction interface uses high-resolution liquid crystal display.
It is further: the circuit trace width 8mil-30mil.
Compared with the existing technology, the technical effect of the utility model is that the utility model is double-sided PCB structure, first device
Part is distributed in the two sides of plank, to give high-frequency digital signal one complete return flow path, and reduces the wiring of DC network, with
And grounding wire impedance is reduced, and to EMC(Electro Magnetic Compatibility, Electro Magnetic Compatibility) play certain screen
The effect of covering, therefore the positive and negative large area of circuit board spreads copper.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1: the main control chip of the circuit board
2: man-machine interaction display screen
3: communication interface circuit.
Specific embodiment
It is a kind of to show and communicate specific integrated circuit plate such as Fig. 1, it is mounted on the main control chip 1 of middle position, with the master
The communication interface circuit 3 that the PORT COM of control chip 1 is connected, is connected man-machine with the PORT COM of the main control chip 1
Interactive interface.
The peripheral circuit of the communication interface circuit and main control chip is distributed in circuit board two sides.Wherein main control chip is outer
Enclose crystal oscillating circuit, driving circuit that circuit includes but is not limited to main control chip, protection circuit, filter circuit, amplifying circuit.
Preferred human-computer interaction interface uses high-resolution liquid crystal display.
The circuit board of the utility model is dual platen, and component side is provided with main control chip.
Component side large area where main control chip spreads copper, and also large area spreads copper at the back side of component side where main control chip.
The circuit trace width 8mil-30mil, above-mentioned each functional module use integrated circuit by peripheral circuit.
It is more clearly understood in order to which the technical problems to be solved in the utility model and effect is further described, below in conjunction with
The utility model is further detailed in accompanying drawings and embodiments.It should be appreciated that embodiment described herein is only used for
Bright the utility model, rather than limitation the scope of the utility model.
Referring to Fig. 1, this circuit board middle position is equipped with main control chip 1, the PORT COM phase with the main control chip 1
The communication interface circuit 3 of connection, human-computer interaction interface --- the high-resolution being connected with the PORT COM of the main control chip 1
Liquid crystal display.
The dedicated display of this soft starter and communication IC plate, the place of application is typically all that all kinds of interference are tighter
The industrial environment of weight, therefore when main control chip 1 is arranged, what is considered first is interference problem, and interference is exactly to refer to described
Main control chip 1 generate interference component or by cable transmitting come industrial field device other interference signals.Such as: it is brilliant
Open-minded, the start and stop of live high capacity motor of brake tube, the interference etc. of live frequency converter.
In the present embodiment, the main control chip 1 is placed in the middle position of entire plank first, plank it is positive and negative
Face large area spreads copper can both increase ground wire area in this way, reduce ground wire when paving copper face product is greater than board area half
Impedance reduces loop area, more communication transfer can be made reliable and stable, reduces from external various electromagnetic interferences etc..
Above-mentioned main circuit is the circuit and imput output circuit of main control chip connection
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
