Description

technical field [0001] The invention belongs to the technical field of industrial cameras, in particular to a positioning circuit for a C3200 camera. Background technique [0002] Industrial cameras are also commonly known as video cameras. Compared with traditional civilian cameras (cameras), they have high image stability, high transmission capabilities, and high anti-interference capabilities. Most industrial cameras on the market are based on CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) chip camera. [0003] Most of the existing industrial cameras use electronic positioning technology. Electronic positioning: when the motor drives the runner to rotate (the rest of the runner is black, and the position corresponding to the positioning point of the runner is a through hole), the circuit board is positioned by three infrared sensors. When the infrared sensor When the emitted light reaches the position of the through hole on the wheel, the p...

Problems solved by technology

[0003] Most of the existing industrial cameras use electronic positioning technology. Electronic positioning: when the motor drives the runner to rotate (the rest of the runner is black, and the position corresponding to the positioning point of the runner is a through hole), the circuit board is positioned by three infrared sensors. When the infrared sensor When the emitted light reaches the position of the through hole on the wheel, the position of the through hole will reflect the light, and the rest of the position will be black to absorb light. The feedback signal to the circuit board changes, and the circuit board controls the stepper motor to stop rotating and reach the designated position. ; The existing electronic positioning device has the problem of inaccurate control
