The four-in-one groove type photoelectric switch is compose of an infrared emitter, an infrared receiver, a signal shaping module, an XOR gate module, a triode Q1, a triode Q2, a rectifier bridge and a sampling resistor. The infrared emitter is corresponding to the infrared receiver in position, the infrared receiver is connected with the XOR gate module via the signal shaping module, the XOR gate module is connected with the triode Q1 and the triode Q2, a side input end of the rectifier bridge is connected with a power supply a end, the other side input end of the rectifier bridge is connected with a power supply b end, the power supply b end is connected with the XOR gate module via the sampling resistor, and the rectifier bridge is connected with the triode Q1. Positive and negative logic conversion and universality for a power supply anode load (NPN) and a power supply cathode load (PNP) are achieved through exchanges between an anode and a cathode. The four-in-one groove type photoelectric switch exhibits usage performance, the imbalance between market supply and demand that NPN type output photoelectric switches are demanded more than PNP type output photoelectric switches so that manufacturers do not want to produce large quantities of the PNP type output photoelectric switches is greatly reduced, the manufacturers no longer worry about product overstocking, and users can buy required products quickly and easily.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of grooved optoelectronic switch.
Background technology
Grooved optoelectronic switch is divided into single type grooved optoelectronic switch and two-in-one type grooved optoelectronic switch, early stage single type grooved optoelectronic switch, only export a kind of pattern: NPN type is often opened output, the normally closed output of NPN type, positive-negative-positive and often opened output, the normally closed output of positive-negative-positive; Two-in-one type grooved optoelectronic switch be the end of the nineties in last century manufacturer of some grooved optoelectronic switch by circuit engineering, improve, can realize that collection NPN type is often opened, the functions of normally closed output or collection positive-negative-positive is often opened, the two-in-one type grooved optoelectronic switch of the normally closed functions being output in.
At present, grooved optoelectronic switch is very extensive in the application of industrial automation, the optoelectronic switch demand of exporting due to NPN type on market is far longer than the optoelectronic switch that positive-negative-positive is exported, manufacturer is reluctant to produce in enormous quantities positive-negative-positive optoelectronic switch, in order to avoid cause overstocked stock, thereby user is not easy to purchase timely positive-negative-positive output photoelectric switch, thereby device fabrication and maintenance are brought to certain impact.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of four-in-one grooved optoelectronic switch.
The scheme of the utility model technical solution problem is to adopt infrared transmitter, infrared remote receiver, signal shaping module, XOR gate module, triode Q

2for positive-negative-positive.Its logical relation is that circuit passes through the sampling resistor of rectifier bridge input to the pin 2 input service voltage signals of XOR gate module, and when sampling resistor collection is high level, the direction of output signal is contrary with the signal logic of receiving tube; When sampling resistor collection is low level, the direction of output signal is identical with the signal logic of receiving tube.Utilize complementary circuit can export the principle that high level again can output low level, realize load and install flexibly, when load connects positive source, triode Q
1work, when load connects the power supply sodium utmost point, triode Q
2work; Comprehensive above-mentioned principle, realizes mixed logic conversion by transposing both positive and negative polarity, and general to positive source load (NPN), power cathode load (PNP).For example, while using, by load one end and triode Q
1emitter and triode Q
2emitter be connected, the load other end can connect power supply a end, when a end is anodal, sampling resistor collects low level, pin 2 low levels of XOR gate module, now unobstructed between infrared transmitter and infrared remote receiver, pin 1 high level of XOR gate module, pin 3 high level of XOR gate module, triode Q
2conducting, load conducting.
The utility model serviceability is reliable, has improved greatly this demand and supply contraction, and manufacturer no longer worries product overloading, and user also can conveniently purchase required product.
