Problems solved by technology

[0005] But the above is only the ideal state of the street lamp work, if the powerful light emitted by the car parked for a long time on the roadside at night is collected by the photosensitive sensor, it will cause the misjudgment of the microprocessor to turn off the street lamp at this time, resulting in unnecessary Impact

Embodiment Construction

[0017] Take controlling street lights as an example:

[0018] (1) Multiple photosensitive sensors of the photosensitive sensor group of the street lamp control system (for example, the photosensitive sensor group has 3 photosensitive sensors) are installed at different geographical locations at different angles.

[0019] (2) Collect the signal values ​​of the photosensitive sensor group, and perform AD operations on the signal values ​​of each photosensitive sensor.

[0020] (3) An AND operation is performed on the signal values ​​of each photosensitive sensor of the above photosensitive sensor group after the AD operation.

[0021] If a certain photosensitive sensor has no signal output, it is judged that the output value of this sensor is "true", and if all photosensitive sensors have no signal output, then it is judged that the output value of this sensor is "false".

[0022] (4) If the result of the AND operation in step (3) is "true", the output value of the photosensiti...

Abstract

The invention discloses a photosensitive sensor set control system control method which comprises the following steps that (1) a plurality of photosensitive sensors of a photosensitive sensor set are respectively arranged in different geographic positions by different angles; (2) signal values of the photosensitive sensor set are collected, AD operation is carried out on the signal values of the photosensitive sensors; (3) AND operation is carried out on the signal values of the photosensitive sensors of the photosensitive sensor set after AD operation; (4) if the result value of AND operation in the step (3) is true, a photosensitive sensor set output value is true; if the result value of AND operation in the step (3) is false, the photosensitive sensor set output value is false; (5) the value obtained in the step (4) is used as a unique signal value of a control system to control the system. According to the method, an interference source can be effectively prevented from interfering the photosensitive sensors, and accordingly an accurate control value is output.

Description

technical field [0001] The invention relates to a control method of a photosensitive sensor group control 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 example, the ideal street light control is to turn off the street l...
