Abstract

The invention relates to the technical field of a camera, particularly to a stepper motor system capable of detecting and error correcting through an angle sensor. A synchronous belt wheel is arranged on the lower end plane of the stepper motor; a motor axis and the friction-less angle sensor are arranged on the upper end plane of the stepper motor; and the friction-less angle sensor can detect a rotary angle of the stepper motor. By mounting the friction-less angle sensor on the upper end plane of the stepper motor, closed loop control on a camera which needs to perform a rotation motion on a monitoring system lens can be realized, so that a current or voltage signal in a real-time position can be obtained; the location of the lens can be solved by the signal and the speed ratio of the synchronous belt wheel on the motor, so that an effect of accurate positioning can be achieved; and automatic error correction is realized without being influenced by interference signals, mechanical vibration and air flow impact.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a stepper motor system for detection and error correction through an angle sensor. Background technique [0002] In the field of video surveillance cameras, such as dome cameras, bolt cameras, pan-tilt cameras, etc., where lens rotation is required, especially dome cameras, it is necessary to rotate up and down about 100 degrees on the vertical plane and 360 degrees on the horizontal plane. horizontal rotation movement. During use, due to the sudden power failure of the system or the interference of external signals, as well as frequent repeated positioning, external mechanical disturbances, such as strong winds, lightning and ground vibrations, will cause the stepper motor to lose steps, thereby accumulating positioning errors. [0003] At present, the method to eliminate the positioning error is to rely on the internal clock of the system to automatically perform a self-...
