Description
Technical field
The utility model relates to the Computer display technical field, relates in particular to a kind of centralized dynamic industrial LCD.
Background technology
Water treatment system is a huger system normally, relates to a lot of structures, pipeline, equipment and also has the technical parameter of the needs controls such as flow, temperature, pH value to show.Common way is with the method for configuration the water treatment industry process flow diagram to be accomplished above the computer with the configuration software of specialty, but be subjected to the restriction of computer monitor display area, usually all need Pagination Display, and can only a people check, in order to realize that many people watch simultaneously, a large-scale display device need to be set, complete the showing of whole technological process.General way is now: a large-scale display panel is set, upper iso-surface patch whole process chart, industrial secondary Displaying Meter is installed to this above large-scale display panel, signal by the output of the analog module above PLC 4-20ma, control the demonstration numeral of secondary Displaying Meter, like this, just can on large-scale display panel, show each technological parameter in real time.As for the demonstration of switching value, it then is the light on and off realization of controlling industrial pilot lamp by the switching value output point of PLC.The characteristics of this display packing are that reliability is high, easy to maintenance, shortcoming is that cost is very high, because take analog quantity and the switching value output point of a large amount of PLC, increase the quantity of PLC configuration output quantity module, simultaneously, the price of secondary Displaying Meter is also somewhat expensive, this causes the holistic cost of display screen to increase, and has limited promoting the use of of display screen.
Summary of the invention
The purpose of this utility model is to provide a kind of centralized dynamic industrial LCD, satisfy complete, concentrated, dynamically show under the condition of water treatment technological process, reduce the cost of manufacture of display screen.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of centralized dynamic industrial LCD, comprise master control display board and sub-panel, the master control display board links to each other with some sub-panels respectively, what of demonstration data volume are the quantity of sub-panel depend on, described master control display board and sub-panel include 8-bit microcontroller, the incoming traffic module, code switch, the LED charactron, LED light, digital pipe driving chip and pilot lamp drive chip, 8-bit microcontroller respectively with digital pipe driving chip, pilot lamp drives chip, code switch and incoming traffic module link to each other, digital pipe driving chip links to each other with the LED charactron, and pilot lamp drives chip and links to each other with LED light; 8-bit microcontroller also links to each other with the outputting communication module on the master control display board.
Described incoming traffic module and outputting communication module are the MAX485 chip, adopt two-wire system half-duplex operation mode.
Communication protocol between described master control display board and each sub-panel adopts MODBUS communication protocol.
Compared with prior art, the beneficial effects of the utility model are: with Micro Controller Unit (MCU) driving charactron display simulation amount data cheaply, drive IED lamp display switch amount data, after the master control display board receives the content that will show from industrial computer, can be simultaneously send different demonstration numerical value to each sub-panel of different I D number, realize complete, concentrated, dynamically show the purpose of water treatment technological process figure.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, it is a kind of centralized dynamic industrial LCD example structure synoptic diagram of the utility model, comprise master control display board and sub-panel, the master control display board links to each other with some sub-panels respectively, what of demonstration data volume are the quantity of sub-panel depend on, the master control display board links to each other with industrial computer, receives demonstration data and follow procedure and distributes to sub-panel.
See Fig. 2, the master control display board comprises that 8-bit microcontroller, incoming traffic module, code switch, LED charactron, LED light, digital pipe driving chip and pilot lamp drive chip, 8-bit microcontroller drives chip, code switch and incoming traffic module with digital pipe driving chip, pilot lamp respectively and links to each other, the incoming traffic module links to each other with the incoming traffic terminal, digital pipe driving chip links to each other with four LED charactrons, and pilot lamp drives chip and links to each other with LED light; 8-bit microcontroller also links to each other with the outputting communication terminal with the outputting communication module successively.LED light mostly is eight the tunnel most.Code switch is used for ID number of setting master control display board.
See Fig. 3, sub-panel comprises that 8-bit microcontroller, incoming traffic module, code switch, LED charactron, LED light, digital pipe driving chip and pilot lamp drive chip, 8-bit microcontroller drives chip, code switch and incoming traffic module with digital pipe driving chip, pilot lamp respectively and links to each other, the incoming traffic module links to each other with the incoming traffic terminal, digital pipe driving chip links to each other with four LED charactrons, and pilot lamp drives chip and links to each other with LED light; LED light mostly is eight the tunnel most.Because carrying out of task is different, the master control display board is different from the inner program of implanting of the 8-bit microcontroller on the sub-panel, and the Single Chip Microcomputer (SCM) program of each sub-panel is identical.The code switch of sub-panel is used for ID number of each sub-panel of setting.
