Abstract

The invention discloses an output point driving controller general for an LED dot matrix billboard. The output point driving controller is characterized by comprising a power module interface, a general LED data interface, an LED data decomposition circuit, a microprocessor, and an output point indicating and driving circuit. Alarm equipment is controlled by outputting alarm point state data input by the LED dot matrix billboard. The output point driving controller general for the LED dot matrix billboard can perfectly solve the problem of alarm of the LED billboard. The controller is not a complete LED billboard control system, and is a module controller which can be flexibly and additionally arranged on an available LED billboard control system. The controller is concise in circuit, small in size and capable of effectively avoiding the defects, and is flexibly and generally applied to the scheme of the available LED billboard control system.

Description

A kind of output point driving governor that is common to LED dot matrix billboard

Technical field

The present invention relates to a kind of output point driving governor of the LED of being common to dot matrix billboard.

Background technology

Along with the development of LED technology, market is increasing to the demand of LED dot matrix billboard, and the competition in market is more and more fierce, thereby causes GeLED banner system manufacturer reduced cost day by day.The function of billboard also more and more becomes popular, unitizes, but has the occasion of specific (special) requirements for some, and such as LED billboard will attach alarm lamp or hummer, these LED see that panel control system is helpless with regard to some.

Reach such effect, first kind of way is to find the LED with this class function to see panel control system; The second way is exactly to add extra IO o controller.The problem of the first scheme is that this class LED control system is very rare; The problem that the second brings is that the system realizing is very burdensome.And both common drawbacks are that price is also very expensive.

Particularly, for the transformation of some existing LED banner systems, the drawback of above two schemes is just more obvious.Versatility is poor, system is burdensome, expensive, for public users, be all difficult to accept.

Summary of the invention

The object of the invention is the defect that cannot directly report to the police for existing LED billboard, and a kind of output point driving governor that ready-made LED sees panel control system that is applied to is provided, for controlling panalarm according to the State-output of alarm set point on LED billboard.

The present invention for achieving the above object, adopts following technical scheme:

An output point driving governor that is common to LED dot matrix billboard, is characterized in that: described controller comprises power module interface, general LED data-interface, LED data decomposition circuit, microprocessor, output point indication and driving circuit;

Described power module interface, for from the power taking of external LED dot matrix billboard, is given other module for power supply;

Described general LED data-interface, for seeing that with external LED dot matrix panel control system plugs into, obtains alarm set point data-signal and offers subsequent conditioning circuit;

Described LED data decomposition circuit, decomposes the one or more alarm set point data-signals that obtain from described general LED data-interface, is transported to described microprocessor;

Described microprocessor is for delivering to output point indication and driving circuit the one or more alarm set point data procession decodings that obtain from described LED data decomposition circuit;

Described output point indication and driving circuit are for driving according to one or more alarm set point raw column data of described microprocessor transmission the external panalarm work of controlling.

Preferred: described output point indication and driving circuit are output as 8 tunnels, adopt relay mode to export.

The output point driving governor of LED dot matrix billboard of the present invention, just in time can perfectly solve the problem that LED billboard is reported to the police.This controller is not that a complete LED sees panel control system, and it is to add flexibly the module controller that ready-made LED sees panel control system to.This controller circuitry is succinct, volume is small and exquisite, can effectively avoid above-mentioned shortcoming, and is common to flexibly ready-made LED control system scheme.

Accompanying drawing explanation

Fig. 1 is principle of the invention block diagram.

Embodiment

A kind of output point driving governor of LED dot matrix billboard is mainly divided into power module interface as shown in Figure 1, general LED data-interface, LED data decomposition circuit, microprocessor, output point indicated and driving circuit.

Each functional module function is respectively:

1. power module interface, the 5V power filter that LED billboard is obtained is processed, thereby ensures the stable running of this controller.

2. general LED data-interface, realizes with external LED and sees plugging into of panel control system, obtains alarm set point data-signal, and data-signal is strengthened to driving force and buffering, thereby makes subsequent conditioning circuit can obtain reliable data-signal.

3. LED data decomposition circuit, decomposes the alarm set point data-signal of the LED data-interface acquisition from general, then gives microprocessor below.

4. microprocessor, the alarm set point data-signal procession decoding that will obtain from LED data decomposition circuit, and the processing such as jitter filtering, then deliver to the indication of rear class output point and driving circuit.

5. output point is indicated and driving circuit, and the signal controlling of being sent here by microprocessor, is specially 8 output reference mark, tunnel, and can be used for controlling the equipment such as 8 road alarm lamps or hummer.For convenient application and all kinds of input equipments, the output point here, we use the mode of relay output, and driving force and versatility are best.

This circuit working flow process is as follows:

1. controller powers on, microprocesser initialization and reset external circuit.

2. the status data of external LED billboard alarm set point light on and off, from general LED data-interface input, arrives LED data decomposition circuit after buffering.

3. LED data decomposition circuit is received after data, decomposites valid data, and is delivered to microprocessor.

4. microprocessor, by the decoding of data ranks, obtains directly controlling the signal of the indication of rear class output point and driving circuit.

5. the control signal that output point indication and driving circuit microprocessor are sent here is strengthened driving, pilot relay switch peripherals.

Claims

1. an output point driving governor that is common to LED dot matrix billboard, is characterized in that: described controller comprises power module interface, general LED data-interface, LED data decomposition circuit, microprocessor, output point indication and driving circuit;

2. the output point driving governor that is common to LED dot matrix billboard according to claim 1, is characterized in that: described output point indication and driving circuit are output as 8 tunnels, adopt relay mode to export.
