Embodiment 1

[0033] Such as figure 1 , figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the meter code wheel device includes a number wheel 3 and a code wheel 1, and 10 Arabic numerals from 0 to 9 are evenly distributed on the cylinder of the number wheel 3; the cylinder of the code wheel 1 There are twenty groups of end-to-end coding patterns evenly distributed on the top, each group of coding patterns is parallel to the transmission shaft 6, and each group of coding patterns is a five-digit binary bar coding pattern, and two adjacent groups of coding patterns have one digit and two digits. The value bar coding patterns are different, and every two groups of coding patterns correspond to an Arabic numeral; a transmission device 2 is arranged between the coding character wheel 1 and the digital character wheel 3; the coding character wheel 1 and the digital character wheel 3 Observation windows 5 are arranged on one side; a direct reading module 4 for reading the code of the e...

Embodiment 2

[0043] Such as image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the meter code wheel device includes a number wheel 3 and a code wheel 1, and 10 Arabic numerals from 0 to 9 are evenly distributed on the cylinder of the number wheel 3; the cylinder of the code wheel 1 There are twenty groups of end-to-end coding patterns evenly distributed on the top, each group of coding patterns is parallel to the transmission shaft 6, and each group of coding patterns is a five-digit binary bar coding pattern, and two adjacent groups of coding patterns have one digit and two digits. The value bar coding patterns are different, and every two groups of coding patterns correspond to an Arabic numeral; the coding character wheel 1 and the digital character wheel 3 are bonded together and installed on the transmission shaft 6 of the digital character wheel 3; Observation windows 5 are arranged on both sides of the character wheel 3 , and a direct reading module 4 for readi...

Abstract

The invention discloses a meter code character wheel device. The meter code character wheel device in a scheme comprises number character wheels and code character wheels; the code character wheels are connected with the number character wheels by transmissions; and an observation window is arranged on one side of each code character wheel and one side of the corresponding number character wheel. The meter code character wheel device in another scheme comprises number character wheels and code character wheels; the code character wheels cling to the number character wheels, and then are mounted on number character wheel transmission shafts; and observation windows are arranged on two sides of each number character wheel. A direct reading module is further arranged on the outer side of the observation window on one side of each code character wheel of the meter code character wheel device in each scheme and is used for reading code patterns of the code character wheel. The meter code character wheel device has the advantages that twenty groups of code patterns are distributed on cylindrical surfaces of the code character wheels of the meter code character wheel device in each scheme, during meter reading, the direct reading modules scan the code patterns and process the code patterns to obtain binary direct reading codes, and decoders in the direct reading modules correct errors of the direct reading codes of the adjacent high-order character wheels according to the direct reading codes of low-order character wheels in comparison with a corresponding high-order character wheel error-correcting code book, so that the problem of misreading during transition of adjacent numbers or linkage carry of two adjacent character wheels is solved.

Description

technical field [0001] The invention relates to a meter counter, in particular to an encoding character wheel device and a direct reading method for the meter counter. Background technique [0002] Direct-reading water meters include resistive, photoelectric, and camera types according to different direct-reading methods. [0003] The photoelectric direct reading remote water meter has the advantages of high reading accuracy, passive, no cumulative storage, anti-jitter, anti-electromagnetic interference, etc. At present, the photoelectric reading method of the character wheel is to install the photoelectric direct reading module on one or both sides of the end face of each character wheel, that is, the photoelectric direct reading module needs to be inserted between the character wheels, and it is not easy to completely isolate the photoelectric direct reading module from the character wheel Open, and the character wheel of this kind of wet water meter is set in the liquid,...
