Embodiment Construction

[0012] Such as figure 1 As shown, an anti-interference photosensitive control light source system includes a photosensitive sensor 1, a microprocessor 2, an electronic switch 3 and a light source 4. There are multiple photosensitive sensors 1, usually 2-3 can achieve the purpose of the present invention , taking a street lamp as an example, multiple photosensitive sensors 1 are installed at different positions and angles.

[0013] The signal of the photosensitive sensor 1 is input into the microprocessor 2 , and the signals of multiple photosensitive sensors 1 are ANDed in the microprocessor 2 , and the result is used as a signal for the microprocessor 2 to control the electronic switch 3 .

[0014] Finally, the microprocessor 2 controls the electronic switch according to the signals of multiple photosensitive sensors 1, and the electronic switch 3 controls the on-off of the light source 4 (such as a street lamp).

[0015] Since the photosensitive sensor 1 is set in different...

Abstract

The invention discloses an anti-interference photosensitive control light source system which comprises photosensitive sensors, a microprocessor, an electronic switch and a light source, wherein signals of the photosensitive sensors are input into the microprocessor, the microprocessor controls the electronic switch according to the signals of the photosensitive sensors, the electronic switch controls turning on and turning off of the light source, a plurality of photosensitive sensors are arranged, the signals of the photosensitive sensors are all input into the microprocessor, the signals of the photosensitive sensors are calculated in the microprocessor, the results are used as a signal which enables the microprocessor to control the electronic switch, therefore, the photosensitive sensors can not all be interfered with even when an interference source exists in some direction or in some position, misjudgment of the microprocessor can not occur, and the light source can be accurately controlled by the system.

Description

technical field [0001] The invention relates to a photosensitive control light source system, in particular to an anti-interference photosensitive control light source system. Background technique [0002] Photosensitive sensors are a type of sensors that use the photosensitivity of photosensitive materials, and use the properties of resistance that changes its own resistance value due to light to play a role. [0003] There are many application examples of controlling the light source by using the photosensitive characteristics. For example, the photosensitive sensor collects a specific signal, and the signal is input to the microprocessor. The microprocessor controls the electronic switch according to the signal of the photosensitive sensor, and the electronic switch controls the light source. to control light sources such as street lamps. [0004] There are also many problems in the application of the above-mentioned light source control. Taking street lights as an examp...
