Application of photoelectric sensor in cash counting machine

The photoelectric sensor is the core component of the money counter. What is the core component of the money counter? It is a photoelectric sensor. The use of money counters is becoming more and more widespread. It is not only used in banks, but also used in many corporate units. It is a very common office tool. Current banknote counters are generally miniaturized in structure, easy to operate, and durable. What makes the banknote counters is the photoelectric sensor, which is a kind of sensor on the banknote counter. The accurate collection of the number of banknotes by the banknote counter is the key to the counting of the banknotes to ensure that the number of banknotes cannot be missed. For this reason, the counter of the banknote counter adopts non-contact infrared photoelectric detection technology, which has the advantages of simple structure, high precision and fast response speed. The counting sensor of the money counter uses two sets of infrared photoelectric sensors. Each sensor is composed of an infrared light-emitting diode and a photosensitive triode that receives infrared light. There is a proper distance between the two. When no banknotes pass, the receiving tube is turned on by light, and the output is 0. When a banknote passes, the infrared light is blocked, the luminous flux of the receiving tube is insufficient, and the output is 1. After the banknote passes, the receiving tube receives the infrared light and conducts it again. In this way, a pulse signal is generated at the output of this part of the circuit. These signals are shaped and amplified by the follow-up circuit and then input into the single-chip microcomputer. The single-chip microcomputer drives the execution motor, and completes the counting and display accordingly. The reason why the banknote counter uses two sets of photoelectric sensors is to detect the integrity of the banknotes and prevent the remaining coins from being counted.

The photoelectric sensor is used to detect the counting of banknotes to realize the accumulation of the number of banknotes. The liquid crystal and external display are used to intuitively display the number of banknotes to the user, and can automatically alert the user when an abnormality occurs. With the development of commercial economy and the requirements of financial automation, the performance of photoelectric sensors can be further improved to meet the requirements.
