Embodiment

[0023] Such as figure 1 As shown, the present invention consists of a light source 1, an optical element 2 connected to the light source 1, a receiver 3 connected to the optical element 2, a comparison unit 4 connected to the receiver 3, and a photoelectric conversion unit connected to the comparison unit 4 Unit 5, a signal processing unit 6 connected to the photoelectric conversion unit 5, a determination unit 7 connected to the signal processing unit 6, and an output port 8 connected to the determination unit 7.

[0024] Wherein, the light source 1 is used to continuously emit light beams to the detection target, which can be realized by using light emitting diodes or laser diodes. The receiver 3 is used to receive the light beam reflected by the detected target, and analyze the light beam to confirm whether the reflected light beam is the light beam emitted by the light source 1, which can be realized by using a photodiode or a phototransistor. The optical element 2 can en...

Abstract

The invention discloses a hybrid high-sensitivity photoelectric sensor system which comprises a light source (1), an optical element (2) connected with the light source (1), a receiver (3) connected with the optical element (2), a comparison unit (4) connected with the receiver (3), a photoelectric conversion unit (5) connected with the comparison unit (4), a signal processing unit (6) connected with the photoelectric conversion unit (5), a determination unit (7) connected with the signal processing unit (6), and an output port (8) connected with the determination unit (7). The hybrid high-sensitivity photoelectric sensor system has excellent anti-electromagnetic interference capability, and prevents the detection precision from being affected by the interference of a magnetic field. The hybrid high-sensitivity photoelectric sensor system is wide in frequency band width, high in sensitivity, excellent in linearity and minimal in dynamic error, and is more suitable for current production requirements.

Description

technical field [0001] The invention relates to a photoelectric sensor, in particular to a hybrid high-sensitivity photoelectric sensor system. Background technique [0002] As the global manufacturing industry becomes more automated, industrial sensors are key to increasing productivity and enhancing safety. Industrial sensors come in all sizes, shapes, and technologies—the most common are those designed with inductive, capacitive, optoelectronic, magnetic, and ultrasonic technologies. Each technology has its strengths and weaknesses, so which sensor to use depends on the requirements of the application. [0003] Photoelectric sensors are widely used in actual detection and control because of their high sensitivity and long detection distance. However, the photoelectric sensors currently used have poor linearity and large dynamic errors during use, and cannot meet the current production needs. Contents of the invention [0004] The object of the present invention is to...
