Problems solved by technology

However, the working range of such systems is limited, and the system does not have scalability; the information exchange between devices adopts digital coding technology, which has the defects of complex implementation technology, poor anti-interference ability, and poor reliability.
[0004] In addition, there are some lighting control systems attached to the building automation system, which use specific protocols, such as Lonworks, BACnet, EIB, etc. These systems are rich in functions, large in scale, complicated to install and debug, must be constructed by professional technicians, and are expensive

Embodiment Construction

[0015] The intelligent lighting system based on radio frequency technology and power line carrier communication technology consists of a wireless remote controller, up to 16 wireless signal forwarding modules, power line receiving modules, and controlled lamps. Each forwarding module corresponds to a room that can support up to 16 power lines. Receiver module, so the system can set 256 groups of device addresses.

[0016] The wireless remote control adopts a working frequency of 315MHz (amateur frequency band), and the maximum control distance is 50m. The remote control uses the PT2262 encoding chip to encode the user's keys and transmits them through the transmitting circuit.

[0017] On the basis of setting 256 groups of addresses, the wireless remote control can realize six kinds of control functions, such as opening, closing, brightening and dimming for specific addresses, and full opening and closing for all controlled devices.

[0018] The power line receiving module de...

Abstract

The disclosed intelligent lighting system based on wireless RF and power line carrier communication technology comprises: a wireless remote controller to emit RF signal, a wireless signal transmit module to convert the received signal into line carrier signal and modulate to the line for transmission, a line receiving module to process signal as command, and the controlled lamp. With address as eight bits, this invention can control 256 devices conveniently.

Description

technical field [0001] The invention relates to a lighting control system, in particular to an intelligent lighting system based on wireless radio frequency technology and power line carrier technology. Background technique [0002] In traditional lighting control systems, energy flow and control flow are integrated, and lighting circuits are controlled through mechanical switches. If multi-point control is to be realized, additional wiring needs to be installed, the wiring workload is heavy, the safety is poor, and mobile centralized remote control cannot be realized. [0003] At present, there are still some small-scale special lighting control systems, and the control switches are connected by bus and wireless. However, this type of system has a limited working range, and the system does not have scalability; the information exchange between devices adopts digital coding technology, which has the defects of complex implementation technology, poor anti-interference abilit...
