Description

Bus-based lighting control device

technical field

The utility model relates to a lighting control device based on a bus.

Background technique

With the continuous development of modern building science and technology and the popularization of information equipment, the intelligentization of control equipment in modern buildings has become the trend of today's building development. However, for a long time, intelligent lighting equipment has been neglected in China, and most buildings still use traditional lighting control methods, which are not conducive to centralized monitoring and management, but also have low efficiency in the use of electric energy, wasting a lot of electric energy.

At present, some small lighting control systems appearing on the market can realize functions such as local and remote lighting control, area lighting, and timing switches, but their control functions are single, and to a large extent still belong to human control, and have not realized automation and intelligent control. Therefore, it is a market demand to develop a centralized and intelligently controlled lighting system.

Detailed ways

Below in conjunction with accompanying drawing and embodiment example the utility model is described further.

As shown in Fig. 1, the utility model provides a kind of lighting control device based on bus, it is characterized in that: comprise PC 1, bus interface module 2, MCU 3, switch circuit 4; Described PC 1 passes bus and bus Interface module 2 is connected with MCU 3, and the output terminal of described MCU 3 is connected with switch circuit 4.

In the first embodiment of the utility model, as shown in Figure 2, the MCU 3 is also connected to the infrared detection module 5, and the infrared detection module 5 adopts a passive infrared detection head to sense infrared radiation. Output high level, and when no one comes, output low level. The trigger signal is sent to the MCU through the inverter through the pre-drive buffer connected by four Schmitt triggers and the pulse width discriminator connected by the monostable trigger and the D flip-flop. The driving ability of the system is enhanced, and at the same time, it is guaranteed to be consistent with the logic potential output by the infrared detection element, and has anti-interference ability. In addition, the bus connection is adopted, and the system line is simple and expandable. Here, the bus of the utility model is also connected with a network interface module 6, so that network management and monitoring can be realized. It can be seen that the utility model can have two control modes, one is centralized control by PC, and the other is intelligent control by using an infrared detection module.

In order to achieve a better power-saving effect, LED lighting is used in current lamps. According to statistics, to achieve the same lighting effect, LED lights can save energy by 90% compared with incandescent lamps. LED has the characteristics of low energy consumption, long life, environmental protection and safety. Therefore, in the second embodiment, as shown in FIG. 4 , the switch circuit 4 is connected with an LED driving module 7 . In this embodiment, we use the AMC7140 driver chip to amplify the signal to a suitable potential to drive the lamp.
