Problems solved by technology
[0003] However, in practical applications, it is found that when the controlled light source is a resistive load, the control terminal can basically generate an accurate coded power waveform signal, but when the controlled light source is a capacitive load or an inductive load, the coded power generated by the control terminal The waveform signal will be interfered by non-resistive load, which will cause the control terminal to fail to send accurate lighting control information

Embodiment Construction
[0055] Whether it is the present invention or the prior art, the architecture of the lighting control system can be as follows figure 1 As shown, it includes: a control terminal for sending lighting control information; a receiving terminal for receiving the lighting control information sent by the control terminal, and controlling the light source according to the lighting control information; a light source for being controlled by the receiving terminal. Wherein, the control end and the receiving end are connected by a power line, that is, the lighting control information is transmitted by the power line. figure 1 The mode shown is a one-to-one correspondence between the control terminal and the receiving terminal. In application, it is also possible to use a mode in which one control terminal corresponds to multiple receiving terminals at the same time. The light source controlled by the receiving terminal is also called a load.

The invention discloses an illumination control information sending method and device and an illumination control system. The illumination control information sending method comprises the steps that illumination control information is encoded, and an encoding control signal composed of a plurality of encode elements is obtained; according to the encoding control signal, a waveform changing circuit is controlled to be switched on and switched off to enable the waveform of a mains supply to produce hopping, and therefore an encoding electric waveform signal with the encoding control signal is generated; the encoding electric waveform signal is transmitted to a receiving end through a power line; the input of the waveform changing circuit is the mains supply, the output of the waveform changing circuit is an encoding electric waveform signal, the waveform changing circuit comprises a first in-phase control branch circuit and a second in-phase branch circuit, and the first in-phase control branch circuit and the second in-phase branch circuit are connected in parallel reversely and used for controlling the positive semi-circle waveform of the mains supply to be switched on and switched off and the negative semi-circle waveform of the mains supply to be switched on and switched off respectively. It is ensured that the waveform changing circuit produces the accurate encoding electric waveform signal whether a controlled light source is a resistive load or a capacitive load or an inductive load.
Description
technical field [0001] The invention relates to the technical field of intelligent lighting control, in particular to a lighting control information sending method, equipment and lighting control system. Background technique [0002] Chinese Invention Patent Publication (publication number: CN101553066A) discloses a lighting control method and its system, and specifically discloses the following technical solution: the control terminal encodes the received lighting control information according to a predetermined coding rule, and uses the coded The signal is used to control the turn-on and turn-off of the waveform changing circuit, so that the waveform of the AC signal jumps, and the encoded power waveform signal is generated, and the encoded power waveform signal is transmitted to the load terminal through the power line network. Since the transition information in the coded power waveform signal carries lighting control information, the load side only needs to decode the r...
