The DALI power temporary wave lighting control equipment adopts Manchester encoding to send information, and sends a frame in each half-wave period, wherein each frame consists of two bits or message start bits. A message consists of 16 frames of four bytes in succession. During normal operation, each half wave transmits a frame.

As shown in fig. 2, the circuit structure diagram of the power temporary wave lighting control device designed by the invention comprises a logic controller 6, a single live wire power taking module 9, a zero crossing detection circuit 8 and a data control circuit 7.

Example 2

The embodiment is a communication message used between the DALI power temporary wave lighting control device and the DALI power temporary wave light source. The DALI master transmits DALI forward frames to the DALI slave 2 over the DALI bus. As shown in fig. 4, the structure of the DALI forward frame includes 19bits, including a 1-bit start bit, an 8-bit address, 8-bit data, and a 2-bit end bit.

The DALI slave control circuit 2 transmits the DALI command of 1 byte to the power ripple circuit 3 through serial communication or other communication means. The power dip circuit 3 uses DLT protocol to dip DALI instructions and transmit DALI power dip light sources.

The frame structure in the DLT protocol includes a start bit, 3 information frames and 4 data frames. In the embodiment of the invention, the DALI power temporary wave lighting control equipment adjusts the light of the DALI power temporary wave light source through the brightness message. After receiving the DALI dimming instruction sent by the DALI slave control circuit 2, the DALI power temporary wave circuit 3 prepares to send a brightness message to the DALI power temporary wave light source. As shown in FIG. 5, the brightness message is shown in the first to third information frames, except for the parity bit p, the rest is temporarily unused, so that the brightness message can be set to 0 or 1 for convenience, the group is temporarily unused, and 8bits of DALI dimming instructions are put into 8bits from b1 to b8 in the first to fourth data frames; as shown in fig. 5, the DALI power temporary wave lighting control device tunes the DALI power temporary wave light source through a color temperature message. After the DALI power temporary wave circuit 3 receives the DALI toning instruction sent by the DALI slave control circuit 2, a color temperature message is ready to be sent to the DALI power temporary wave light source. As shown in FIG. 5, the color temperature message is set to "0" or "1" for convenience, and the first to third information frames are temporarily reserved except for the parity bit p, and the DALI color temperature instruction of 8bits is put into 8bits of b 1-b 8 in the first to fourth data frames.

Each data transmission starts with the Most Significant Bit (MSB).

Example 3

In this embodiment, the DALI power temporary wave light source matched with the present invention is connected to the DALI power temporary wave lighting control device through a power line, and receives the DALI dimming and toning instruction sent by the DALI power temporary wave lighting control device.
