Embodiment Construction

[0016] Such as figure 1 The output point drive controller of the LED dot matrix billboard shown 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:

[0018] 1. The power module interface filters the 5V power obtained by the LED signboard to ensure the stable operation of the controller.

[0019] 2. The universal LED data interface realizes the connection with the external LED billboard control system, obtains the alarm point data signal, and strengthens the driving force and buffer of the data signal, so that the subsequent circuit can obtain the 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. The microprocessor will decode the alarm point ...

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 for LED dot matrix billboards. Background technique [0002] With the continuous development of LED technology, the market has more and more demand for LED dot matrix signage, and the market competition is becoming more and more fierce, which has led to increasingly reduced costs for LED signage system manufacturers. The functions of the billboards are becoming more and more popular and unified, but for some occasions with special requirements, such as LED billboards with warning lights or buzzers, these LED billboard control systems are somewhat powerless. [0003] To achieve this effect, the first way is to find an LED signage control system with this kind of function; 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 implemented system i...
