Abstract

The invention provides an intelligent controller used for public lighting facilities. A combined relay alternating current contactor provided with a wire head used for external connection is connected with an input terminal of a microcomputer photosensitive timer, an output terminal of the microcomputer photosensitive timer is connected with a relay coil J, a contact switch, a crystal diode, a resistor R, and a photoelectric diode through conducting wires, and is connected with a combined relay alternating current contactor coil at the same time; and the output terminal of the microcomputer photosensitive timer is further connected with a transformer, a rectifier, an electrolytic capacitor, a diode, the relay coil J, a crystal triode, and another diode. The public lighting facility intelligent controller can be used in cooperation with the lighting facilities, and is capable of presetting electricity service time limit in a using process, so that an aim of realizing intelligent control of switching on and off in manners of timing control and photosensitive regulation can be achieved, and electricity saving and public facility management are facilitated.

Example Embodiment

[0012] The embodiment of the drawing shows: the combined relay AC contactor 1 with the external wire head 8 is connected to the input end of the microcomputer photosensitive timer 3, and the output port of the microcomputer photosensitive timer 3 is connected to the relay coil J contact through a wire Switch 16, crystal diode 11, resistor R9 and photodiode 10 are connected to the combined relay AC contactor coil CJ15 at the same time; then connect the transformer 12, rectifier bridge 13, electrolytic capacitor 4, crystal diode 5, relay coil J2, transistor 6 And another crystal diode 5. The combined relay AC contactor coil CJ15 is provided with a wire connected to the combined relay AC contactor 1. The relay coil J contact switch 16 is provided with a wire connected to the relay coil J2, and the resistor 7 and the photosensitive resistor 14 form a loop with the rectifier bridge 13.
[0013] The working process of the lighting intelligent controller: preset the switch time limit of the microcomputer photosensitive timer 3 for electricity consumption every night, the lighting intelligent controller works normally, and the lighting appliances are used normally. When the rainy day comes, the light will drop. Although it is not within the preset power time limit, the microcomputer photosensitive timer 3 is turned on immediately. At the same time, the resistance value of the photoresistor becomes larger due to the drop of light. The transistor 6 is saturated and turned on, and the relay coil J2 When the power is turned on, the combined relay AC contactor coil CJ15 is turned on to turn on the lighting power supply. When the closing time is reached, the photosensitive timer 3 automatically cuts off the power, and the combined relay AC contactor coil CJ15 cuts off the lighting power. So as to achieve the purpose of intelligent lighting control.
[0014] In application, the three-phase AC power is introduced from the ABCN terminal at the upper end of the combined relay AC contactor 1, from K 1 K 2 K 3 Output on the N terminal to provide power for lighting appliances.
