Photoelectric sensor

At present, currency counting machine is used more and more widely, but the bank commonly used equipment, but also gradually become the cash flow of the enterprises and institutions necessary office equipment. Now the currency counting machine general structure miniaturization, simple, durable, dba5a06dk and achievement counting machines is a photoelectric sensor, photoelectric sensor is the necessary cash registers teco electric motor ac.

Counting machine, accurate collection bill number is the key detector count, must ensure that the bill number can not be omitted, this counter currency count machine adopts the non-contact infrared photoelectric detection technology, gear motor has the advantages of simple structure, high precision and fast response etc.. Counting sensor for currency count machine adopts two groups of infrared photoelectric sensor. Each sensor consists of an infrared emitting diode and a receiving infrared phototransistor, there is a proper distance is left between the, when no bill through, receiving tube by the light and conduction, the output of 0. When there is money through the moment, blocking the infrared receiving tube, luminous flux, the output of 1. The bill passed, and received the infrared receiving tube conduction. This generates a pulse signal at the output end of the signal circuit, the circuit shaping amplifier input after the MCU, MCU driving motor, and complete the count and display. Counting machine adopt two sets of photoelectric sensor, in order to avoid the integrity test paper, 12 volt dc motors banknote is included in the teco dc motor speed control.

Through the photoelectric sensor to detect the cumulative count of money and then realize the bill number, the liquid crystal and the external display intuitively the bill number is displayed to the user, and the abnormal can automatically alarm to users. With the development of commercial economy and financial system, the performance of the photoelectric sensor must be further improved to meet the requirements PC Remote Control.
