Intelligent controller used for public lighting facilities

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.
