Embodiment Construction

[0016] Such as figure 1 The output point drive controller of an LED dot matrix kanban is mainly divided into a power module interface, a general LED data interface, an LED data decomposition circuit, a microprocessor, an output point indication and a drive circuit.

[0017] The functions of each functional module are as follows:

[0018] 1. Power module interface, filter the 5V power supply obtained by the LED signboard, so as to ensure the stable operation of the controller.

[0019] 2. The universal LED data interface realizes the connection with the external LED kanban control system, obtains the data signal of the alarm point, and strengthens the driving force and buffering of the data signal, so that the subsequent circuit can obtain a reliable data signal.

[0020] 3. The LED data decomposition circuit decomposes the alarm point data signal obtained from the general LED data interface, and then sends it to the subsequent microprocessor.

[0021] 4. Microprocessor, the ...

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 [0001] The invention relates to an output point drive controller commonly used in LED dot-matrix kanbans. Background technique [0002] With the continuous development of LED technology, the market demand for LED dot-matrix kanban is increasing, and the market competition is becoming more and more fierce, which leads to the cost reduction of LED kanban system manufacturers. The functions of kanban are becoming more and more popular and unified, but for some occasions with special requirements, such as LED kanban with alarm lights or buzzers, these LED kanban control systems are somewhat powerless. [0003] To achieve this effect, the first way is to find an LED kanban control system with such functions; the second way is to add an additional IO output controller. The problem with the first solution is that this type of LED control system is very rare; the problem with the second solution is that the realized system is very cumbersome. And the common disadva...
