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
Technical field
The present invention relates to a kind of output point drive control device being common to led dot matrix billboard.
Background technology
With the continuous development of led technology, market is increasing to the demand of led dot matrix billboard, and the competition in market is got over
It is fiercer to come, thus leading to each led banner system manufacturer increasingly reduced cost.The function of billboard also increasingly moves towards popular
Change, unitized, but have the occasion of particular/special requirement for some, such as led billboard will attach alarm lamp or buzzer, these led
Kanban-control system is helpless with regard to some.
Reach such effect, first kind of way is to find the led Kanban-control system with this kind of function；Second side
Formula is exactly to add extra io o controller.The problem of the first scheme is that this kind of led control system is very rare；Second
The problem brought is that the system realized is very burdensome.And both are that price is also very expensive the drawbacks of common.
The drawbacks of especially for the transformation of some existing led banner systems, both the above scheme, just becomes apparent from.General
Property is poor, system is burdensome, expensive, is all difficult to accept for public users.
Content of the invention
Present invention aim at the defect that cannot directly be reported to the police for existing led billboard, one kind is provided to be applied to existing
Become an output point drive control device of led Kanban-control system, control for the State- output according to alarm point on led billboard
Warning device.
The present invention for achieving the above object, adopts the following technical scheme that
A kind of output point drive control device being common to led dot matrix billboard it is characterised in that: described controller includes power supply
Module interface, general led data-interface, led data decomposition circuit, microprocessor, output point instruction and drive circuit；
Described power module interface is used for from outside led dot matrix billboard power taking, to other module for power supply；
Described general led data-interface is used for plugging into outside led dot matrix Kanban-control system, obtains warning point data
Signal is supplied to subsequent conditioning circuit；
Described led data decomposition circuit, by the one or more warning points obtaining from described general led data-interface
According to signal decomposition, it is transported to described microprocessor；
Described microprocessor is used for carrying out the one or more warning point data obtaining from described led data decomposition circuit
Output point instruction and drive circuit is delivered to after ranks decoding；
Described output point instruction and drive circuit are used for the one or more alarm point row according to the transmission of described microprocessor
The external warning device of column data drive control works.
Preferred: described output point instruction and drive circuit are output as 8 tunnels, are exported using relay mode.
The output point drive control device of led dot matrix billboard of the present invention, just can perfectly solve asking of led billboard warning
Topic.This controller is not a complete led Kanban-control system, and it is flexibly to be added to ready-made led Kanban-control system
A module controller.This controller circuitry is succinct, compact, effectively can avoid disadvantages mentioned above, and flexibly lead to
For ready-made led control system scheme.
Brief description
Fig. 1 is principle of the invention block diagram.
Specific embodiment
A kind of output point drive control device of led dot matrix billboard is broadly divided into power module interface, general as shown in Figure 1
Led data-interface, led data decomposition circuit, microprocessor, output point instruction and drive circuit.
Each functional module function is respectively as follows:
1. power module interface, the 5v power filter that led billboard is obtained is processed, thus ensureing stablizing of this controller
Running.
2. general led data-interface, realization is plugged into outside led Kanban-control system, obtains warning point data letter
Number, and driving force and buffering are strengthened to data signal, so that subsequent conditioning circuit can obtain reliable data signal.
3. led data decomposition circuit, the alarm point data signal obtaining from general led data-interface is decomposed, then
Give microprocessor below.
4. microprocessor, the alarm point data signal procession obtaining from led data decomposition circuit is decoded, and
Jitter filtering etc. is processed, and is then delivered to the instruction of rear class output point and drive circuit.
5. output point instruction and drive circuit, is controlled by the signal that microprocessor is sent, specially 8 tunnel output control points,
And can be used to control the equipment such as 8 road alarm lamps or buzzer.Application and all kinds of input equipments for convenience, output here
Point, we use the mode of relay output, driving force and versatility best.
This circuit workflow is as follows:
1. electricity, microprocesser initialization and the external circuit that resets on controller.
2. the status data of outside led billboard alarm point light on and off inputs from general led data-interface, reaches after buffering
Led data decomposition circuit.
3. after led data decomposition circuit receives data, decomposite valid data, and be delivered to microprocessor.
4. data ranks are decoded by microprocessor, obtain directly controlling the instruction of rear class output point and drive circuit
Signal.
5. the control signal that output point indicates and drive circuit microprocessor is sent is strengthened driving, and control relay switchs
Ancillary equipment.
