The invention discloses an emitter coupled logic type photoelectric sensor system based on stimulant logic control. The system comprises an output port (8), a light source (1), an optical component (2) in connection with the light source (1), a receiver (3) in connection with the optical component (2), a comparing unit (4) in connection with the receiver (3), a photo-electric conversion unit (5) in connection with the comparing unit (4), an emitter coupled type amplifying unit (6) in connection with the photo-electric conversion unit (5) and a judging unit (7) in connection with the output port (8). Between the emitter coupled type amplifying unit (6) and the judging unit (7) is further provided a stimulant logic control unit (9). According to the embodiments of the invention, the system is provided with an emitter coupled type amplifying unit which has an amplifying function and prevents the magnetic field of the system and the detected signals from interfering with each other, and therefore, the detected signals become more stable. Further, the introduction of a stimulant logic control unit enables the system to be higher in signal frequency processing.
Description
technical field [0001] The invention relates to a photoelectric sensor, in particular to an emitter coupled photoelectric sensor system based on excitation logic control. 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 detection accuracy of the currently used photoelectric sensors is not high, and cannot meet the current production needs. Contents of the invention [0004] The purpose of the present inven...
