Abstract

The invention provides a remote-transmitting meter two-dimensional encoding print wheel photoelectric direct reading device, which eliminates the defects of a plurality of detecting components, complex encoding algorithm and so on in the prior photoelectric direct reading device basically. The remote-transmitting meter two-dimensional encoding print wheel photoelectric direct reading device comprises a meter support, a print wheel axle, a multidigit encoding print wheel, a code reader and a decoder. In the technical essence of the invention, the encoding print wheel adopts a two-dimensional encoding print wheel with angles and brightness; the left side of the cylindrical face of the print wheel is provided with an encoding strip with discrete values from zero level to the ninth level or continuous analog values so that the values on the encoding strip correspond to the angles of the numbers from 0 to 9 on the right side of the cylindrical face; the code reader consists of an LED and a receiving triode. A brightness base sheet and a dynamic base code reader are fixed in a groove on the end of the frame of the code reader. The remote-transmitting meter two-dimensional encoding print wheel photoelectric direct reading device uses the two-dimensional encoding print wheel with angles and brightness and the unique direct reading device having self-correcting and calibration function, which is compact in structure and processed simply. Sensors are reduced; the cost is reduced; the volume is reduced; and values are ensured to be read correctly.

Description

technical field [0001] The present invention relates to a photoelectric code-reading device for remote meter code wheel, in particular to a remote meter with simple structure and automatic adjustment and calibration function applied to meters such as remote metering water meters, electric meters, and gas meters. The photoelectric direct reading device of the one-dimensional coding character wheel is different from the existing "angle one-dimensional coding character wheel" in that it adopts the "angle plus brightness" two-dimensional coding character wheel and its unique automatic adjustment photoelectric direct reading device. Background technique [0002] At present, with the rapid development of electronic digital technology, the traditional mechanical structures of meters such as water meters, electricity meters, and gas meters are gradually being replaced by mechanical-electrical-integrated coding wheel photoelectric direct-reading devices. According to relevant patent ...

Problems solved by technology

[0004] The object of the present invention is to provide a well-designed two-dimensional code wheel photoelectric direct reading device for remote meters, which not only fundamentally solves the problem of many detection devices, high cost, large volume, and problems existing in existing photoelectric direct reading devices. The coding algorithm is complex and other problems, and because of the two-dimensional coding character wheel with "angle plus brightness" and its unique direct reading device with automatic adjustment and calibration function, the code can be read only by using a sensor of one code reading point The value information corresponding to the angle on the character wheel can be translated into the corresponding coded character wheel number, so it has the advantages of significantly reducing sensor components, compact structure, simple processing, lower cost, smaller volume, and ensuring accurate readings.
