Abstract

The invention discloses a direct-reading photoelectric sensor and a metering device thereof. Due to the adoption of a photoelectric principle, no contact exists between a character wheel and a signal acquisition device during the rotation of the character wheel, and the metering of a gas meter is not influenced; and phenomena, such as fatigue and damage of the device, produced due to the contact can be prevented. A direct-reading meter reading system greatly saves electric energy consumption due to no power consumption at ordinary times. The direct-reading photoelectric sensor comprises a plurality of photoelectric panels, a plurality of character wheels, a plurality of carry gears and a master control board, wherein both surfaces of each of the plurality of photoelectric panels are provided with symmetrical light emitting tubes and light receiving tubes respectively; the light emitting tubes and the light receiving tubes of every two adjacent photoelectric panels are opposite to each other; the plurality of character wheels are arranged between every two adjacent photoelectric panels respectively; a wheel disc of each character wheel is provided with a cambered non-light tight groove which is concentric with the wheel disc; the plurality of carry gears are arranged between every two adjacent character wheels respectively and engaged with wheel rims of the character wheels on two sides; and the master control board is in signal connection with the plurality of photoelectric panels.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to a direct-reading photoelectric sensor and a measuring instrument thereof. Background technique [0002] With the development of science and technology, automation can be seen everywhere in people's lives. However, the management of water, electricity, gas, and heat, which are closely related to people's lives, is still in the manual stage. For example, manual meter reading is difficult, labor-intensive, and inefficient. , and the accuracy and timeliness cannot be reliably guaranteed, which has caused great trouble to both users and public utility management departments. For this reason, the technology of automatic meter reading has been paid more and more attention to by people, and it is particularly important how the metering instruments related to it send the metering value in the form of digital signals. [0003] Existing metering instruments are pulse-sending metering i...
