Abstract

The invention provides an optoelectronic data collection device of a mechanical pointer counter. The optoelectronic data collection device comprises a pointer, a pointer shaft key, a pointer output shaft, a dial, dial circles, dial marks, a positioning screw, a positioning hole, a positioning threaded hole, a counter gear box, a pointer position photoelectric sensing device, a serial communicator and a singlechip system, wherein the pointer position photoelectric sensing device comprises a light emission plate and a light receiving plate, as well as a diaphragm plate and a fan-shaped shade sheet located between the light emission plate and the light receiving plate. The pointer position photoelectric sensing device transfers the detected position of the pointer to the singlechip system; and the singlechip system processes the detected position via a singlechip procedure to obtain reading data of the counter and sends the reading data to the outside via the serial communicator. And meanwhile, the invention further provides a data processing method of the optoelectronic data collection device of the mechanical pointer counter. According to the device and the method, the requirement on the manufacturing process is low and the reading has no dead zone. The device and the method are applied to the instruments having the counter used for instruments such as water meters and gas meters in displaying, storing and sending the data to the outside.

Description

Technical field [0001] The invention relates to the technical application field of sensors and single-chip microcomputers, in particular to a mechanical pointer type counter photoelectric data acquisition device and a data processing method thereof. Background technique [0002] The mechanical pointer counter is a traditional counting device, which is widely used in various water and gas meters. Its performance is stable and reliable. However, because it does not have the ability to automatically output data, it is used as a display and storage. In the data industry, meter reading can only be done manually, which is time-consuming, labor-intensive, and costly. Summary of the invention [0003] In order to meet the needs of automatic meter reading and continue to maintain some of the basic advantages of mechanical pointer counters, the present invention installs a photoelectric sensor device between the counter gear box and the dial of the traditional mechanical pointer counter. T...
