In the intelligent control board, a control unit mainly used for controlling industrial equipment is connected through a communication cable with a human-computer interaction unit mainly used for human-computer interaction and data storage. In the control unit, a micro control unit (MCU) is connected with a power module, an N-path analogue input module, an N-path analogue output module, an N-path input and output switching value module and a communication module, wherein the power module supplies power to the MCU; the N-path analogue input module inputs a signal to the MCU; the N-path analogue output module outputs the signal processed by the MCU; the N-path input and output switching value module controls external equipment and feeds information back to the MCU; and the communication module realizes communication with the other modules. Compared with the prior art, the intelligent control board has the advantages and the beneficial effects that: 1, a control part and a human-computer interface are implemented separately; 2, difficulty in development and development cost are greatly decreased; 3, system complexity is decreased, and reliability is improved; 4, the control part and the human-computer interface can be arranged separately; and 5, the control part and the human-computer interface are more universal.

Description

A kind of Based Intelligent Control plate

Technical field

The utility model technical scheme relates to the Based Intelligent Control plate technique field that is used for Industry Control.

Background technology

Since coming out from computing machine, early stage user is to be main with the computer professional, but along with computing machine extensively gets into the people's work sphere of life, change has taken place in the computer user, and the domestic consumer of non-computer specialty has become user's main body.This great change becomes the availability issue of computing machine and becomes increasingly conspicuous.Which type of should be man-machine interface? How to go to build such interface? People begin to pay close attention to and study these problems.These problems had both related to the people and had also related to the relevant subject of computing machine and some, as: psychology, human factor (Human Factor s), sociology, linguistics etc.The development of Along with computer technology, the widening of application, thus brought different theoretical methods.Since the eighties; The research of man-machine interface has had unprecedented development, and popularizing rapidly of microcomputer played important impetus to this. at industrial control field, because the developing rapidly of microprocessor; Also brought the man-machine interface great variety; Command language formula interface from based on character mode is in the graphic user interface epoch up till now, and it makes man-machine interaction more natural.

The useful plc of present man-machine interface HIM (LCD colour liquid crystal display device) realizes, also has to realize based on the embedded controller of arm.The utility model with the arm microprocessor realize similar, so introduce the scheme that realizes based on the arm microprocessor.

1, the Graphics Design of man-machine interface is based upon on the embedded OS and realizes, data access is handled button simultaneously, control input, information such as output.This just requires microprocessor that the sufficiently high travelling speed internal memory enough big with expansion arranged, and need increase other functional chip, system complex simultaneously.

2, the pcb board based on arm must be a multilayer board, and it is with high costs to make a plate.

3, the system complex development and testing time cycle is long.

4, because the arm processor will be handled man-machine interface, also to handle button simultaneously, input, control informations such as output, reliability decrease.

The utility model content

The purpose of the utility model is: a kind of Based Intelligent Control plate of utility model, to overcome existing defective, realize that control section and man-machine interface can be installed separately, and versatility is better.

According to above-mentioned purpose, the technical scheme of the utility model is: a kind of Based Intelligent Control plate, this Based Intelligent Control plate is by mainly being used for controlling the control module of commercial unit and mainly being used for the man-machine interaction unit of man-machine interaction and data storage and linking to each other through communication cable.

Described control module is that MCU links to each other with power module, N road analog input module, N road analog output module, N road input amount module and communication module, electric power source pair of module MCU power supply; N road analog input module is that the MCU signal is imported; N road analog output module is the signal output after MCU handles; N road input amount module feeds back to MCU to the control of external unit; Communication module is realized the communication with other module.

Described man-machine interaction unit is that MCU links to each other with the HMI display module with power module, storage data module, communication module respectively; Electric power source pair of module MCU power supply; The HMI display module shows the MCU process result; The storage data module is stored data; Communication module is realized the communication with other module.

Described man-machine interface HIM uses the liquid crystal display that carries internal memory; Control flow just can be controlled through corresponding order with simple serial ports or spi mouth; Data storage uses special module to operate, and two parts come interaction data through communications protocol, and these two parts respectively have a microprocessor.

Described microprocessor is 8 or 16 microprocessors, and the pcb plate is a dual platen.

Described man-machine interface and data storage two parts are through the communication cable interaction data, and described two parts are for being installed separately, and control section is installed in the industry control scene, and the man-machine interface control section is installed in the place of being convenient to personnel operation.

Compared with prior art, advantage of the utility model and beneficial effect are:

1, control section and man-machine interface separately realize;

2, development difficulty and cost of development reduce widely;

3, system complexity reduces and has improved reliability;

4, control section and man-machine interface can be installed separately;

5, control section and man-machine interface versatility are better.

Embodiment

In conjunction with Fig. 1, be a kind of Based Intelligent Control plate embodiment block diagram, this Based Intelligent Control plate is along with the development of technology, new chip, the appearance of new functional module makes primary processor can handle prior data, peripherally handles through corresponding functional module.The utility model scheme is divided two parts control module part and man-machine interaction unit part; Control module part mainly is used for controlling commercial unit, and input amount, analog module are arranged.Man-machine interaction unit part mainly is used for man-machine interaction and data storage.Wherein man-machine interface HIM uses the liquid crystal display that carries internal memory, and control flow just can be controlled through corresponding order with simple serial ports or spi mouth, and data storage uses special module to operate.Two parts come interaction data through communications protocol, and these two parts respectively have a microprocessor, and the change of the system of each several part is simple relatively like this, available 8 or 16 microprocessors, and the pcb plate can be used dual platen, has reduced the plate-making cost.8 or 16 microprocessor relative arm processor development difficulties and cost of development have reduced greatly, want information processed to reduce owing to divide two parts to do every part simultaneously, and the system complexity reduction has so just improved reliability.Two parts are to come interaction data through communication cable, and two parts can be installed separately like this, and control section can be installed to the industry control scene, and the man-machine interface control section can be installed to the place of being convenient to personnel operation.
