摘要

An indoor power line transmission control system, includes: a transforming dimming controller (1), which is used to load, onto an electrical signal, a received dimming signal sent by a mobile terminal or input by a user in a touch-control manner, and send the electrical signal loaded with the dimming signal to a dimming driver (2); and the dimming driver, which is electrically connected with the transforming dimming controller and a dimming luminaire (3), and used to read the electrical signal loaded with the dimming signal, and adjust a gray scale of the dimming luminaire according to the read electrical signal. By replacing a normal switch with the transforming dimming controller and by using the dimming driver and transmitting the dimming signal to the dimming luminaire by means of a power line, flexibility of having no wiring, simple extension and smart dimming are realized and energy can be saved.

TECHNICAL FIELD

The present application relates to the field of smart home technologies, and in particular to an indoor power line transmission control system.

BACKGROUND

At present, with the development of the concept of smart home, we see more and more smart home implementation schemes, especially luminaire lighting schemes, which are divided into wireless schemes and wired schemes. The wireless schemes are based on Bluetooth, wifi, zigbee and the like. The wired schemes are based on analog electrical level, pwm, triac and the like. The existing wireless schemes allow for the flexibility of having no wiring and has the potential for continuous bursting in application forms, but DHCP is required to dynamically allocate an IP address and a software layer is required to bind a domain name each time the wireless terminal is started, making it necessary to have special associated software and technical guidance in setting up the application. In addition, due to the high complexity and the generally low reliability of the system, the user experience is poor. The existing wired schemes have better reliability and convenient configuration for use, but have a poor continuous expansion capability in application due to the fact that the control lines need to be arranged in advance during decoration with low flexibility and high cost. Further, the existing wireless/wired schemes have no dimming function to automatically adjust the power of the illumination according to ambient lighting, resulting in low energy consumption efficiency.

Therefore, the technical problem to be solved urgently is to integrate the advantages of the existing wireless and wired schemes so as to realize flexibility of having no wiring, simple extension, smart dimming, and thereby saving energy.
