Non-contact online type infrared photoelectric sensor detection instrument

Abstract

The invention discloses a non-contact online type infrared photoelectric sensor detection instrument. The instrument comprises a single-chip computer, a receiving detecting module which is connected with the single-chip computer and a transmission module; the receiving detecting module comprises a receiving detecting probe and feeds back a detecting signal of a to-be-detected target equipment sensor transmission tube to the single-chip computer, and a receiving detecting result is given by the single-chip computer; the transmission module comprises transmission detecting probe which is used for transmitting an infrared optical signal with a designated frequency and a non-contact type detecting probe which is used for transmitting an electromagnetic signal through a guiding wire when the infrared signal with the designated frequency is received by the detecting target equipment sensor receiving tube, the detection result is output to the single-chip computer by the non-contact type detection probe, the impulse number of the transmitted signal and the receiving number are compared by the single-chip computer and judged, whether or not a received signal is a signal with the designatedfrequency is determined, and the detection result is given. The instrument can meet the demand of the rapid positioning of a sensor of most brand equipment maintaining manufacturers.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a non-contact online infrared photoelectric sensor detector. Background technique [0002] At present, with the development of financial self-service machines, there is a huge amount of equipment. With the operation of the equipment and the accumulation of dust, the failure rate of infrared sensors is very high. The transmitter tube and receiver tube of the sensor are invisible and intangible because the media medium is infrared, which brings great inconvenience to maintenance personnel. Routine maintenance detection methods are either tested and confirmed by the substitution method, or tested and judged one by one with a multimeter. No matter which method is used, it is necessary to continuously switch between power-off and power-on to judge whether the infrared sensor is good or bad. The time has a great impact on the customer experience. [0003] Therefore, there is an ur...
