Embodiment approach 1

[0056] Signal generation:

[0057] The multi-channel lighting control device transmits information by changing the time interval of alternating current zero crossing through the switch controller. The switch controller changes the zero-crossing time interval of the alternating current according to the control data to be sent, and forms an information flow to send out. Realize the transmission of data.

[0058] By artificially changing the zero-crossing time interval, there is a large difference between the changed time interval value and the original interval value to represent the existence of information. The switch controller in the present invention can control the on-off of the alternating current, when sending information, cut off the alternating current, produce a voltage and be the state of 0 volts, artificially produce a zero-crossing point t2, and the duration is fifteen times of the usual zero-crossing time interval one-third. In the present invention, the moment...

Embodiment approach 2

[0064] Signal generation:

[0065] The zero-crossing point of the alternating current is detected by the zero-crossing circuit, and the duration of the zero-crossing point is usually very short. The present lighting control device characterizes the presence of information by varying the duration of the zero crossing. The switch controller changes the zero-crossing duration of the alternating current according to the control data to be sent, and forms an information flow to send out. Realize the transmission of data.

[0066] Normally, the alternating current generates a zero-crossing point every half cycle, and the zero-crossing time detected by the zero-crossing circuit lasts very short, which is set to t1. When the information is to be transmitted, the zero-crossing duration is extended, and the duration is one-third of the half cycle One, set it to t0.

[0067] In the agreed communication protocol in the lighting control device, t0 is defined as data 0 and t1 is defined ...

Abstract

The invention, which relates to the illumination control field, discloses a multi-path illumination controlling apparatus using two alternating-current power lines for realizing power supplying and controlling. More particularly, the invention relates to a method and system capable of completing power supplying and communication controlling on multi-path illumination lamps only by using two alternating-current power lines. The whole multi-path illumination system, that is the multi-path illumination controlling apparatus, comprises a switch controller, a plurality of lamp controllers, two power lines and a plurality of lamps. An input terminal of the switch controller of the multi-path illumination controlling apparatus is connected with an alternating-current leading-in point; and an output terminal of the switch controller is connected with the two power lines to carry out line laying. A plurality of lamp controller installing points are arranged at the two power lines; input terminals of all the lamp controllers are connected to the two power lines; and illumination lamps are respectively installed at output terminals of all the lamp controllers. According to the invention, problems of many wires and complex wiring, long installing time, high using difficulty, poor flexibility, complex circuit during communication signal receiving and restoring, and high manufacturing cost can be solved.

Description

technical field [0001] The invention discloses a multi-channel lighting control device powered and controlled by two AC power lines, relates to the field of lighting control, and in particular relates to a method for completing power supply and communication control of multiple lighting lamps with only two AC power lines and system. Background technique [0002] At present, the commonly used lighting systems are laid in series with the three elements of switches, power cables, and lamps. But there is the following problem: when multi-channel lighting is to be implemented and lighting fixtures are to be individually controlled, at least one power line must be laid for each lighting fixture, and some need two. The consumption of power connection wires required for multi-channel lighting is considerable, and the wiring is complicated, time-consuming and heavy, and maintenance is quite difficult. In order to solve this wiring problem, people have developed several common contr...
