Embodiment Construction

[0024] A high-precision direct-reading gas meter of the present invention such as figure 1 As shown, it is mainly composed of a housing 1, an air inlet 3 and an air outlet 2 provided on the housing 1, a battery box 7 installed in the housing 1, a counter 4, a master control circuit board 5 and an LCD display 6. A battery is housed in the battery box 7, which supplies power for the circuit part of the whole gas meter. The master control circuit board 5 carries out electrical control to the whole gas meter, and a processor 5-1 is mainly welded thereon. The air inlet hole 3 and the air outlet hole 2 communicate with the counter 4, and the counter 4 is pushed to count. The mechanical count value obtained by the counter 4 is returned to the processor 5-1 for digital processing to obtain a digital count value. The LCD display screen 6 is connected to the processor 5-1 to display the electronic count value processed by the processor 5-1.

Abstract

The invention discloses a high-precision direct-reading gas meter, comprising a counter and a processor, wherein the counter comprises a fixed bracket, a code disk consisting of two or more than two counting character wheels, and counting circuit boards. An axial run-through non-light-tight groove is arranged on the lateral surface of each counting character wheel; one counting circuit board is respectively arranged at the two sides of each counting character wheel, and seven pairs of infrared transmitting-receiving tube pairs are respectively arranged on the two counting circuit boards; and the processor is electrically connected with a transmitting circuit board and a receiving circuit board and is used for controlling the infrared transmitting tube to emit light, performing binary cycle encoding according to the level fed back by the infrared receiving tube, and converting into decimal count values to display or output. According to the high-precision direct-reading gas meter disclosed by the invention, not only the counting precision of the gas meter is increased and zero error is basically achieved, but also the precision requirements for manufacturing and mounting of counters are correspondingly reduced.

Description

technical field [0001] The invention relates to a gas meter, in particular to a high-precision direct-reading gas meter. Background technique [0002] Since the use of water, electricity and gas in the last century, metering meters have been introduced. The traditional gas meter uses the principle of mechanical counting. It can be understood from the metering principle of the gas meter that the rollers in the glass window of the gas meter are used To calculate the gas consumption, you can see from the outside of the gas meter that there is a scroll wheel with numbers in the small glass window. There are also seven digits on the scroll wheel, the four digits before the decimal point are black, and the last three digits are red. When using Qi, you can see the lowest number wheel turning slowly. When the lowest digit turns from 0 to 9, the digit wheel in front of it rotates once to increase the reading by one digit, which is the carry. Obviously, this is also a decimal counti...
