However, this method generally uses a gear to determine the value of the character wheel, because a disc has 360°, and it is impossible to accurately determine the value of its carry state simply from a gear, resulting in inaccurate readings, which may be accumulated over time. lead to bigger mistakes

Embodiment Construction
[0015] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises reading disk 1, and the side of reading disk 1 is provided with first circular ring 2 and second circular ring 3, and first circular ring 2 is provided with some shaded areas 4 and blank areas 5 evenly spaced, and the second circular ring The ring 3 is also provided with a shadow area 4 and a blank area 5 , five outer sensors 6 are arranged on the side of the second ring 3 , and one inner sensor 7 is arranged on the side of the first ring 2 . The central angles of the reading disk 1 corresponding to the shaded area 4 and the blank area 5 on the first ring 2 are 20° and 16° respectively. The second ring 3 is followed by a blank area 5 with a central angle of 108 °, a shadow area 4 with a central angle of 162 °, a blank area 5 with a central angle of 36 °, and a shadow area 4 with a central angle of 54 °. constitute. The two ends of the blank area 5 with a central a...

The invention relates to a character wheel counter of a thick-thin two-gear meter, and particularly relates to the character wheel counter of the thick-thin two-gear meter which is applicable to the metering of flow of gas, liquid, electricity and the like. The character wheel counter of the thick-thin two-gear meter comprises a reading disk, and is characterized in that a first circular ring and a second circular ring are arranged on the side surface of the reading disk, a plurality of shadow areas and blank areas are uniformly arranged on the first circular ring at intervals, shadow areas and blank areas are also arranged on the second circular ring, five outer sensors are arranged on the side surface of the second circular ring, and an inner sensor is arranged on the side surface of the first circular ring. The character wheel counter has the beneficial effects that through the comparison between two gears, a numerical value of the character wheel counter can be more accurately determined; and the character wheel counter is simple in structure, long in service life and easy to produce, thus making a great contribution to the metering of the flow of the gas, liquid, electricity and the like.
Description
(1) Technical field [0001] The invention relates to a character-wheel counter for a meter with two grades of thickness, in particular to a character-wheel counter for a meter with two grades of thickness, which is suitable for measuring the flow of gas, liquid, electricity, etc. (2) Background technology [0002] With the current technology, gas, water, and electricity meters all have the function of direct reading and remote transmission. It is no longer necessary for meter readers to go door-to-door to manually read meters. Only the sensors installed on the meters can be remotely transmitted to the computer. Meters usually used to measure the flow of gas, liquid, electricity, etc., its working principle is to pass gas, liquid, and dielectric through the flow detection device in the instrument, the flow detection device drives the transmission device, and then the transmission device drives the reading disc to rotate, When the character code is set on the reading disc, the ...
