Problems solved by technology

However, since the addresses of lamps are generally set during installation, it is inevitable to introduce human error in large-scale systems; in addition, because switches and jumpers will introduce additional hardware, it not only increases the cost, but also increases the volume of the lamp controller, which affects the control. The miniaturization of the device is also not conducive to the waterproof and dustproof of the lamps

Embodiment Construction

[0021] Based on the addressing method above, we have designed a set of "LED decorative lighting control system" that can be automatically addressed. In this case, the system consists of an addressing controller and several LED controllers. The addressing controller and LED controllers are connected to the same RS485 bus, which expands the DMX512 protocol; there is a pair of controllers between two adjacent controllers The lines are connected to each other and communicate with each other through the serial port. In this case, the addressing controller and the LED controller adopt the same hardware structure, and its structural diagram is shown in Figure 2. Serial port 1 is used to communicate with the upper-level controller, serial port 2 is used to communicate with the lower-level controller, serial port 1 of the addressing controller and serial port 2 of the last LED controller are idle.

[0022] In terms of specific protocol design, the start code (Start Code) byte of the D...

Abstract

An automatic addressable method for the distributed multiprocessor LED control system is the traditional RS485 added with a group of end-to-end control circuit, to make LED controller not only connect with the same RS485, but also link with each other to a chain. It completes address and addressing of the system microprocessor through software agreement to identify mapping of the address and the physical location of lamp. It is applicable to microcontroller addressable technology for the control of LED intelligent landscape lighting as well as the other intelligent systems or automation system requiring microcontroller address.

Description

technical field [0001] The invention belongs to the technical field of micro-controller addressing in light-emitting diode (LED) intelligent landscape lighting control, and is also applicable to the technical field that requires micro-controller addressing in other intelligent systems or automation systems. Background technique [0002] With the rapid development of microelectronics technology, the functions of microprocessors are getting stronger, their prices are getting cheaper, and their volumes are getting smaller and smaller, which makes distributed multi-microprocessing systems widely used. Lamps controlled by microprocessors can have communication functions, so the large-scale LED intelligent landscape lighting system constructed from this is widely used in landscape lighting such as buildings and entertainment venues. [0003] In the LED intelligent lighting control system, the existing technology usually uses the DMX512 protocol to give each lamp processor a unique...
