Photoelectric coding counting device and photoelectric coding counter

Abstract

The invention discloses a photoelectric coding counting device and a photoelectric coding counter thereof, wherein the photoelectric coding counting device is provided with an infrared transmitting plate, a counter print wheel and an infrared receiver plate, and coding holes are arranged on the counter print wheel, and an infrared receiver tube can transform photoelectric signals into a group of binary codes according to whether infrared lights sent by an infrared transmitting tube pass through the coding holes and are received by the infrared receiver tube. The photoelectric coding counter comprises a counter bracket, a circuit board and five groups of photoelectric coding counting devices, wherein the circuit board is provided with a microprocessor, a photoelectric sampling circuit and a wireless transceiving circuit, wherein infrared receiver tubes in each group of photoelectric coding counting devices can transform the photoelectric signals of the infrared transmitting tubes in relative group into a group binary codes, each group of binary codes are transformed into some decimal digit value of the photoelectric coding counter after being decoded by the microprocessor, each decimal value can combine into an integral actual value, and the actual value is transmitted to a counter system through controlling the wireless transceiving circuit by the microprocessor. The device has simple structure design and accurate and reliable data collection, and can conveniently realize the wireless automatic meter reading and real-timely monitor the operation condition of a fuel gas meter.

Description

Technical field: [0001] The invention relates to a photoelectric coding and counting device based on a wireless sensor network and a photoelectric coding counter thereof, which are mainly used in metering and counting and metering information transmission of household membrane gas meters, and can conveniently form a wireless automatic meter reading network. Background technique: [0002] With the advancement of urbanization, the popularization and application of piped natural gas, and the increasing consumption of household membrane gas meters, the problems of production management, safety management, and meter reading management of gas operating enterprises have also become prominent. In order to adapt to the modern management of gas operating enterprises, there is an increasing demand for smart metering gas meters such as prepaid gas meters and remote automatic meter reading. At present, most of the counting sensor devices of smart gas meters are equipped with a reed switc...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the magnetic attraction between the magnet and the metal sheet of the reed switch, the transmission resistance of the character wheel increases and shakes, resulting in a decrease in the measurement sensitivity and measurement accuracy of the gas meter;

[0005] 2. Reed switches and Hall elements rely on magnetic attraction and magnetic polarity changes to generate electrical signal pulses, and external magnetic interference cannot collect signals;
