Direct-reading gas meters in the market are mostly used for wired direct reading for many years, and all the direct-reading gas meters are in a post-payment mode. The device is characterized by accurate reading and extremely low power consumption when the reading is not carried out at ordinary times. But the wire direct-reading wiring project is complex, high in cost and inconvenient to maintain, so that the popularization of the wire direct-reading wiring project is restricted. In the existing emerging wireless spread spectrum technology of the Internet of things, a wireless direct reading mechanism is introduced; the wireless direct-reading meter generally loads a reading circuit to directly read the reading on each character wheel of the counter before uploading data, and then uploads the data to the concentrator, so that the direct-reading interval is one day or a plurality of days, the power consumption of the direct-reading meter is greatly reduced, but the timeliness of the reading is lost, and particularly, under the condition that the current network meter requires to implement a prepayment mode, the reading with larger interval is difficult to reflect the real-time change of balance at the meter end, so that the prepayment mode is difficult to accurately implement in the wireless direct-reading network meter.

S2, when reading is started, reading the balance X of the user before deduction and the current gas unit price A; when X is not more than 0, closing the gas supply valve; when X is larger than 0, sending a query instruction to a gas meter of a user terminal to obtain a current gas reading C, after the current gas reading C is obtained, reading a last gas reading B and a current gas unit price A, and calculating a specific calculation formula of a user balance Y after fee deduction, wherein the specific calculation formula comprises the following steps:
Y＝X-A*(C-B)；
if Y is less than or equal to 0, the balance of the user is insufficient and recharging is needed, and the gas supply valve is closed;
in this embodiment, if the current balance of the first user is 4 yuan, a query instruction is sent to a gas meter of a user terminal to obtain a current gas reading, and if the current gas reading is 51.3, the unit price of the current gas is 2 yuan per cube; the balance of the user after the user performs fee deduction is equal to 4-2(51.3-50) and equal to 1.4; because Y is greater than 0, the user does not need to recharge and does not need to close the gas supply valve; and if the current balance of the user B is 0 yuan, the gas supply valve is directly closed.
S3, updating the user balance X before deducting fee to be equal to the user balance Y after deducting fee and reading the current time T of the system, if the current time T of the system belongs to the idle time T0The idle reading interval △ t is passed0S2 will be repeated; if the current time T of the system belongs to the busy time period T1Then the busy hour reading interval △ t is passed1S2 is repeated.
