This invention discloses an algorithm to prevent position detection jitter. It constructs a region PS centered on the vehicle body and its surrounding region PE. Region PE is further divided into sub-regions, namely a detection region and a critical region. The algorithm determines whether the current key's detection position is within region PS. If it is, the key position type remains unchanged, and it then determines whether the key has entered the PS detection region. If so, the position type is changed to PS region. Otherwise, it checks whether the current key's detection position is within region PE. If it is within PE, it continues to determine whether the key is within any of the sub-region detection positions. If so, it continues to determine whether the key has entered the sub-region detection region. If so, the key position type is changed to sub-region position type. If not within PE, the key position is set to an unknown region, and the algorithm then determines whether to update the current position type. This prevents misjudgment of the key position due to position jumps caused by interference.

This invention relates to the field of metering instrument data acquisition technology, specifically to an anti-interference coded reading sensor and reading method for water meters. The method involves mapping the resistance value of each code disk area to three mechanical connection states, corresponding to different operating conditions of the water meter's discontinuous gear mechanism. The width of the dividing line between the digits 9 and 0 on the code disk is greater than the width of the dividing lines between other digits. This results in a shorter time window and later triggering of the brush when passing through this critical zone, providing a clear timing distinction window for the carry-over action of the higher-order digits and effectively avoiding misjudgments when multiple digits carry over simultaneously. During reading, the resistance corresponding to different digits is measured, and a software algorithm based on gear rules and water flow constraints is used for state verification, eliminating illegal reading combinations caused by mechanical intermittents or water hammer reversal. This solves the problem of code skipping and errors in the carry-over critical zone of existing direct-reading sensors, improving the reliability and accuracy of electronic readings.
