Abstract
The utility model provides an intelligent controller for driving an LED digital tube, which is characterized by comprising a microprocessor, wherein the microprocessor is connected with a host machine through a communication interface, is connected with an address/mode setting switch and drives an LED digital display unit through a driving unit. The utility model has the advantage that: 1, the driving unit is integrated on the controller, and the LED digital display unit comprises only a small number of discrete components, thereby reducing the cost and volume of the LED digital display unit; 2, a high-performance RISC reduced instruction set singlechip is used as a data operation and processing core, and the real-time response to the communication of the host computer and the accuracy of self data processing are ensured; 3, according to different application environments, the setting of the address/mode setting switch is changed, and different work modes are switched.
Description
Technical field
The utility model relates to a kind of intelligent controller of driving LED charactron.
Background technology
In Automatic monitoring systems, analog data mainly is to realize showing by the LED charactron display of all kinds of specifications.From present domestic applicable cases, along with LED light emitting diode kind is maked rapid progress, quality parameter improves constantly, the driver module that driving data shows also has continuous technological innovation and the update of the product that emerges in an endless stream.
Refresh form according to LED charactron video data, LED charactron display is divided into dynamic scan and two kinds of drive patterns of static scanning.Dynamic scan adopts software to circulate constantly and drives whole LED each points, utilizes the demonstration that effect reaches whole screen flicker free that persists of vision.Static scanning display application hardware latch display drive content is only carried out corresponding LED and is shown refresh scan when Data Update.Because two kinds of type of drive all have advantage separately, application is respectively arranged on driver module, but the means that realize are constantly released because of advanced person's components and parts and quality stage construction, Costco Wholesale great disparity up and down, each has something to recommend him competition situation appear in the lifting of application software on product is realized.
Make a general survey of the driver module production development that driving data shows from commercial chemical industry robotization control platform, substantially be update along the display element device, drive controlling from early stage transistor driving to the TTL integrated circuit, the application that extends into present large scale integrated circuit special chip all makes the driver module technology of LED demonstration towards high-efficiency multi-function, miniaturization and industrialized development.
The LED charactron display of present most producers has all disposed single-chip microcomputer separately, to realize that independently dynamically demonstration and host computer are realized display driver by the RS232/422 data-interface with making communications protocol by oneself.Be characterized in distributed control, single led charactron display volume is bigger, and cost is higher.In Automatic monitoring systems, a lot of occasions need intensive demonstration mass data, so just cause whole cost bigger, have increased user's input.
Summary of the invention
The purpose of this utility model is to provide a kind of control device of the driving LED charactron that reduces cost.
In order to achieve the above object, the technical solution of the utility model has provided a kind of intelligent controller of driving LED charactron, it is characterized in that: comprise microprocessor, microprocessor links to each other with host computer by communication interface, be connected with address/mode setting switch on microprocessor, microprocessor is by drive unit drives LED charactron display unit.
Further, described communication interface is the RS-485 interface, and described microprocessor is a RISC reduced instruction set computer single-chip microcomputer.
The utility model has the advantages that: 1, driver element is concentrated on the controller, on LED charactron display unit, only contain the minority resolution element, reduced the cost and the volume of LED charactron display unit.2, adopting high performance RISC reduced instruction set computer single-chip microcomputer is that data operation is handled core, has guaranteed the accuracy that the real-time responsiveness and its data of upper machine communication are handled.3, can change address/mode setting switch setting according to different applied environments, switch different working modes.
Description of drawings
The intelligent controller circuit block diagram of a kind of driving LED charactron that Fig. 1 provides for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the intelligent controller of a kind of driving LED charactron that provides for the utility model, comprise microprocessor, microprocessor links to each other with host computer by communication interface, be connected with address/mode setting switch on microprocessor, microprocessor is by drive unit drives LED charactron display unit.Wherein, communication interface is selected the RS-485 interface for use, and microprocessor is selected RISC reduced instruction set computer single-chip microcomputer for use, and other unit modules are available circuit or outsourcing product.
The utility model adopts SMD components and parts on hardware design, make the complete machine structure compactization.Driver element unification simultaneously concentrates on the intelligent controller, only contains the minority resolution element on the LED charactron display unit, reduces the cost and the volume of LED charactron display unit.
Adopting high-performance AVR series monolithic is that data operation is handled core, has guaranteed the accuracy that the real-time responsiveness and its data of upper machine communication are handled.Intelligent controller has extremely strong adaptability and dirigibility, can change address/mode setting switch setting according to different applied environments, switches multiple mode of operation.
