Embodiment Construction

[0009] see figure 1 , the present invention includes a host computer monitoring module, an Ethernet communication module, an MCU control module, an AC / DC power supply module, an LED driver module, a fuel gauge module and a memory module. The MCU control module uses a single-chip microcomputer as the main control chip. It receives the TCP data packet sent by the host computer through Ethernet, and after unpacking, outputs a PWM signal with a corresponding duty cycle to the LED driver module. In addition, the MCU control module receives the electricity meter sent The instantaneous power signal is processed into a TCP packet, and then sent to the host computer through Ethernet for real-time display. The input terminal of the AC / DC power conversion module is directly connected to the 220V voltage, and the output terminal can output a variety of DC voltages, respectively supplying power for the Ethernet communication module, MCU control module, LED driver module, and fuel gauge mod...

Abstract

The invention discloses an Ethernet light-emitting diode (LED) control system with acquirable electric quantity. The Ethernet LED control system comprises an upper computer monitoring module, an Ethernet control module, a micro control unit (MCU) control module, an alternating-current / direct-current (AC / DC) power module, an LED driving module, an electric quantity metering module and a storage module, wherein the upper computer monitoring module can remotely control the LED lamp and monitor the electric quantity of the system in real time; the Ethernet control module receives the data transmitted by the upper computer monitoring module and transmits the processed data to the MCU control module; the MCU control module outputs a pulse width modulation (PWM) signal in a corresponding duty ratio to control the output current of the LED driving module according to the received data; and the electric quantity metering module meters the power consumption of the system and transmits the processed power consumption to be displayed in real time through the MCU control module. The Ethernet LED control system can be directly connected with the LED lamp, can be used for scene illumination, stadium illumination and the like, can monitor the electric energy consumed by the circuit and judge the abnormality of the circuit in real time and is simple in equipment, low in cost and convenient to mount, operate, maintain and manage; and the operation is not limited by environment and distance.

Description

technical field [0001] The invention relates to an LED control system, in particular to an LED control system controlled by Ethernet and capable of real-time power collection. Background technique [0002] In recent years, LED has developed rapidly due to its advantages of high energy saving, long life, and environmental protection. High-power LED lighting fixtures have begun to be popularized and applied in road lighting, tunnel lighting, venue lighting and other places, and the corresponding demand for LED control systems has also had higher requirements. Not only the switch control, brightness adjustment and remote control of the LED lamps are required, but also the real-time monitoring of the power consumption of the system is required in order to save energy and judge the current working status of the system. At present, the LED control systems on the market do not have the functions of real-time monitoring of the power consumption of the system and judging whether the...
