Description

Controlled terminal for intelligent lighting control system

Technical Field

The utility model relates to an illumination control technical field especially relates to a controlled terminal for wisdom illumination control system.

Background

At present, lighting control devices in the market mainly adopt a centralized wiring technology and a power carrier technology. The centralized wiring technology is mainly applied to indoor lighting or industrial lighting, and the power line carrier technology is generally used for controlling outdoor street lamps or landscape lamps. The traditional centralized wiring technology adopts modes of RS485, CAN bus and the like, and the implementation method is that all lighting devices to be controlled are connected by signal lines and are centralized on a master control device, and then a user carries out man-machine interaction through the master control device, so that the purpose of controlling the devices is achieved.

The power line carrier technology is a communication method that a line for transmitting power of an existing street lamp is used as a communication channel to transmit digital signals, and the signals are modulated onto a high-frequency carrier wave through an LC resonance circuit and a power amplification circuit to be transmitted. The street lamps only use the existing power line as a basic framework, have no more special requirements on the power transmission line, need to be additionally provided with street lamp centralized control equipment, realize the function of modulating, demodulating and converting power line carriers into corresponding signals, and realize data communication and equipment control.

In the power carrier technology, a distribution transformer has a blocking effect on power carrier signals, so that the power carrier signals can be transmitted only in the range of one distribution transformer area. The three-phase power line has great signal loss (10dB-30dB), when the communication distance is very close, different phases may receive signals, and the common power carrier signal can only be transmitted on the single-phase power line. Different signal coupling modes have different losses to the power carrier signal, and the coupling modes are wire-ground coupling and wire-neutral coupling. The line-to-ground coupling scheme has a power carrier signal loss of tens of dB less than the line-to-neutral coupling scheme, but the line-to-ground coupling scheme is not suitable for all local power systems. In addition, the power line has pulse interference, so that the power line causes high reduction of carrier signals. When the load on the power line is heavy, the line impedance can reach below 1 ohm, resulting in high reduction of the carrier signal. In practice, when the power line is empty, the point-to-point carrier signal can be transmitted over several kilometers. But when the load on the power line is heavy, only tens of meters can be transmitted.

The product of the centralized wiring technology adopts a mode of centralized additional wiring, and generally has higher manufacturing cost, longer construction period and complex after-sale maintenance. The installation of walking the line in advance promptly during house fitment, if the circuit damages, the house equipment control breaks down, and cost of maintenance is quite high. This is also a big problem that puzzles the popularization of smart homes. The centralized wiring technology has higher installation requirement, is complex and complicated to install, and is very inconvenient especially for intelligent transformation of traditional control.

Therefore, in order to realize an intelligent lighting control system which is simple to install, free of wiring, strong in expansibility, simple to maintain, free of pulse interference, stable in signal, low in loss and suitable for various regions, a controlled terminal for the intelligent lighting control system needs to be designed.
