Control information transmission system, control information sending and receiving method and equipment

Abstract

The embodiment of the invention discloses a control information transmitting system and a control information sending and receiving method and device. The control information transmitting system comprises a first device used for sending control information and a second device used for receiving the control information, wherein the first device and the second device are connected through a power line network, the first device is used for modulating the frequency of mains supply according to the control information so that an electricity signal can be obtained, the electricity signal is transmitted to the second device through the power line network, and the second device is used for demodulating the electricity signal so that the control information can be restored. According to the control information transmitting system and the control information sending and receiving method and device, transmission of the control information is achieved in the mode that the frequency of the mains supply is regulated, and the control information transmitting method is different from an existing control information transmitting method, and different solutions are provided for the transmission of the control information. The control information transmitting system and the control information sending and receiving method and device have the advantages of achieving low-cost transmission of the control information on the basis that an existing power line is not changed, and being particularly suitable for low-cost occasions, such as the occasion for intelligent lighting control over a lighting light source.

Description

technical field [0001] The invention relates to the technical field of intelligent lighting control, in particular to a control information transmission system, a method and equipment for sending and receiving control information. Background technique [0002] With the development of lighting technology, users have higher and higher requirements for lighting sources. For example, for household LED light bulbs, in addition to the functions of color temperature adjustment and brightness adjustment, it is also required to perform functions such as scene control, group control, and color adjustment. Due to the improvement of functional requirements for lighting sources, correspondingly higher requirements are put forward for intelligent lighting control systems that control these light sources. [0003] At present, in the intelligent lighting control system, for the transmission of lighting control information, wireless or wired methods can be used. The wireless method mainly ...

Problems solved by technology

But the cost of Bluetooth module or WIFI module is usually higher or even several times higher than the cost of lighting source, so it is not practical to apply Bluetooth module or WIFI module to the control of lighting source

Among them, the wired method mainly refers to the use of power line carrier communication (a power communication method using transmission lines as the transmission medium of carrier signals) to transmit lighting control information. This method requires at least one power line carrier communication module, and the current module The mainstream price ranges from 50 to 200 yuan, so there is also a problem of high cost in the way of using power line carrier communication to transmit lighting control information, and the home position of power line carrier communication usually needs to install a wave trap, which is also a problem. make it subject to certain limitations in the promotion of
