Problems solved by technology

[0002] The gas meters widely used at present are generally ordinary gas meters with conventional mechanical counters. This kind of meter needs to be manually checked one by one and then record the gas consumption, and manual charging is adopted, which wastes a lot of manpower and material resources.

Embodiment Construction

[0016] Please also refer to Figure 1 to Figure 7 , IC card table signal acquisition device of the present invention comprises a conventional counter 1 and a signal conversion device 2 fixed on the conventional counter 1 .

[0017] The structure of the conventional counter 1 is the same as that of the existing counter, including a frame 11, 5 integer digit wheels 12, 3 small digit digit wheels, a character wheel shaft 16, 7 counter rotating wheels 17, and a counter rotating wheel shaft 18 . The number of teeth and the modulus of the five integer digit wheels 12 and the three decimal digit wheels are the same. The three decimal digit wheels are respectively 0.1 character wheel 13 , 0.01 character wheel 14 and 0.001 character wheel 15 . The character wheel shaft 16 and the counter rotating wheel shaft 18 are fixed on the frame 11 in parallel, the 5 integer-digit character wheels 12 and the 3 decimal-digit character wheels are sequentially set on the character wheel shaft 16, a...

Abstract

An IC card meter signal acquisition device comprises a conventional counter and a signal conversion device fixed on the conventional counter. An 'eight-teeth' driving wheel of the signal conversion device is in close fit with a driving shaft and matched with a toggle tooth on a 0.1 character wheel of the conventional counter, a modulus of the 'eight-teeth' driving wheel is identical with that of the toggle teeth on the 0.1 character wheel of the conventional counter, an 'inverse V-shaped' signal wheel of the signal conversion device is fixed and sheathed on an end of the driving shaft, the 'inverse V-shaped' signal wheel is equally divided into four equal parts, an infrared transmitting tube and an infrared receiving tube have equal height and are perpendicularly fixed on a circuit board face to face, and the 'inverse V-shaped' signal wheel is positioned between the infrared transmitting tube and the infrared receiving tube. The IC card meter signal acquisition device has advantages of simple structure and conversion of a reading of the conventional counter into an electronic signal for displaying the measurement reading, thus allowing to automatically acquire the reading of a gas meter by an IC card.

Description

【Technical field】 [0001] The invention relates to a gas flow meter, in particular to a signal acquisition device for an IC card gas meter used for measuring gas consumption in a gas pipeline. 【Background technique】 [0002] The gas meters widely used at present are generally ordinary gas meters with conventional mechanical counters. This kind of meters need to manually check the tables one by one and then record the gas consumption, and use manual charging, which wastes a lot of manpower and material resources. In order to solve this problem, there is an IC card gas meter. If the IC card is inserted into the gas meter, the monthly gas consumption and the equipment fee that needs to be paid can be calculated through the IC card, which greatly improves the work efficiency. and accuracy. When the data of the gas meter is read by the IC card, the reading of the conventional counter of the gas meter needs to be converted into an electronic signal to display the metering reading....
