The bottom surface of cylinder, swing rod is shaft-like, and swing rod is arranged at the circle centre position of LED light source plate.
It is preferred that, downwards, LED light source plate is made up of LED light source plate LED and drive circuit, and LED is no less than eight.
It is preferred that, swing rod is fixed on the circle centre position of LED light source plate lower surface by hinge, and swing rod is shorter than the height of detection cylinder
Degree.
It is preferred that, sensor base plate is arranged on base plate by optical detecting unit according to matrix array mode.
It is preferred that, optical detecting unit includes phototriode, and the colelctor electrode of phototriode passes through biasing resistor and power supply
Positive pole VCC is connected, and the emitter stage of phototriode is connected to the ground, and the signal of the current collection extremely detection unit of phototriode is defeated
Go out to hold OUT.
The utility model has the advantages and positive effects of：By conventional levels instrument electronization and digitlization, it is easy to automatic
Regulation and control；Swing rod is arranged between sensor base plate and LED light source plate, and the detection unit for not covering part by swing rod is defeated
Go out high level, and the detection unit for covering part by swing rod exports low level, and because each detection unit is with array way
It can be obtained after being arranged in sensor base plate, therefore output signal of the single-chip microcomputer by detecting each detection unit by logical operation
Go out the horizontal direction position of current tested belt, sensor circuit be only made up of light source and multiple optical detecting units realize it is non-
