Prepaid gas reading method

Abstract

The invention discloses a prepaid gas reading method. The method comprises the following steps: acquiring user information and system information; reading the relevant user information and system information: firstly, different reading intervals are adopted according to different periods: if the user balance before deduction is smaller than 0, reading is not conducted and a gas supply valve is closed, and reading is conducted if the user balance before deduction is larger than 0; secondly, automatic error correction is conducted, the previous reading is retained for comparison with the currentreading, and the current reading is discarded when the difference is much larger than the normal daily amount or the difference is negative; updating the user balance before deduction and conductingjudgement according to current system time: the next reading interval is the busy reading interval in the busy period, and the next reading interval is the leisure reading interval in the leisure period. According to the method, different reading intervals are adopted according to different busy or leisure periods, reading and deduction scientificity and accuracy are improved, and the risk of users' malicious arrearage is reduced in combination with a prepayment method.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to a prepaid gas reading method. Background technique [0002] Over the years, most of the direct-reading gas meters on the market are used for wired direct-reading, and all of them are post-paid models. It is characterized by accurate readings and extremely low power consumption when not reading normally. However, due to the complexity of the wired direct-reading wiring project, high cost, and inconvenient maintenance, it has restricted its promotion. In the current Internet of Things wireless spread spectrum technology, the "wireless direct reading" mechanism is introduced; because the wireless direct reading meter generally loads the reading circuit before uploading data, "directly reads" the readings on each character wheel of the counter, and then uploads the data To the concentrator, so the "direct reading" interval is one or several days, so although its power consumptio...

However, due to the complexity of the wired direct-reading wiring project, high cost, and inconvenient maintenance, its promotion is restricted.

In the current Internet of Things wireless spread spectrum technology, the "wireless direct reading" mechanism is introduced; because the wireless direct reading meter generally loads the reading circuit before uploading data, "directly reads" the readings on each character wheel of the counter, and then uploads the data To the concentrator, so the "direct reading" interval is one or several days, so although its power consumption is greatly reduced, but the timeliness of reading is lost, especially in the case of the current network table requiring the implementation of "prepaid" mode, This kind of reading with a large gap is difficult to reflect the real-time change of the "balance" at the meter end, which makes it difficult to accurately realize the prepaid mode in the wireless direct reading network meter
