Problems solved by technology

The above gas meters each have some advantages and disadvantages, but there is a common problem: these gas meters cannot perform the billing of the amount that the gas company urgently needs, and cannot effectively support step-by-step pricing and time-of-use billing
However, this kind of gas meter cannot make adaptive changes in time when the gas company adjusts the price, and a large-scale modification procedure is required. Therefore, the adaptability of this scheme is low

Embodiment approach 1

[0025] During specific implementation, the optimized implementation scheme 1 is:

[0026] The monthly summary storage unit of gas usage, the daily summary storage unit of gas usage, and the detailed storage unit of daily gas usage all adopt a two-parameter partition structure of time stamp plus gas usage assignment, and the time stamp adopts year, month, day, hour and minute model;

[0027] The MCU has the following functions after calling the detailed data generation and storage instructions of gas consumption:

[0028] First, compare the latest generated timestamp with the timestamp of the last record in the monthly summary storage unit of gas usage, if not in the same month, create a new record in the monthly summary storage unit of gas usage, and assign the gas usage For the deduction amount, assign the time stamp as the clock signal to which it belongs; if it is the same month, update the last record of the monthly summary storage unit of gas usage, and assign the gas us...

example 1

[0033]Example 1: Set the minimum time period for generating detailed gas usage data on the gas meter, that is, the time period, to 5 minutes. A total of 3120 pulse signals were sent out. Generally speaking, 1000 pulse signals are 1 deduction amount, corresponding to the gas flow rate of 1 cubic meter used by the user, the components in the gas meter will work together in the following way:

[0034] During the period from 9:00 to 9:03, because the pulse metering module has sent 1000 pulse signals to the MCU in total; At 9:03, it is also sent to the gas usage detailed storage module. Under the control of the MCU, firstly, compare the timestamp of the last record of the monthly summary storage unit in the gas usage detailed storage module, that is, 7:02 on January 1, 2012, with the new timestamp, that is, 2012 At 9:03 on January 10, when it is confirmed that it is the same month, update the last record of the monthly summary storage unit, and the gas consumption will increase...

example 2

[0047] Example 2: Set the minimum time period for generating detailed gas usage data on the gas meter, that is, the time period, to 5 minutes. A total of 3420 pulse signals are sent out, and the components in the gas meter will work together in the following way:

[0048] During the period from 9:00 to 9:05, the pulse metering module has sent a total of 1300 pulse signals to the MCU. After reaching 1000 pulse signals, the MCU will send a deduction amount to the gas consumption detailed storage module; at the same time, the clock The signal is also sent to the gas consumption detail storage module at 9:05 on January 10, 2012. Under the control of the MCU, first, compare the timestamp of the last record of the monthly summary storage unit, ie, 7:05 on January 1, 2012, with the new clock signal, ie, 09:05 on January 10, 2012 , after confirming that it is the same month, update the last record of the monthly summary storage unit, and the gas consumption is accumulated by 1 cubi...

Abstract

A gas meter with a gas usage amount detail data generation and storage function mainly aims to solve the problem that an existing gas meter cannot effectively support multistep charging or time-sharing charging. The gas meter with the gas usage amount detail data generation and storage function is characterized in that the gas meter is provided with a clock module, a gas usage amount detail storage module and a program storage unit. The gas usage amount detail storage module comprises a monthly collection and storage unit, a daily collection and storage unit, and a daily detail storage unit. The clock module is controlled by a microprogrammed control unit (MCU) to provide the units of the gas usage amount detail storage module with timestamp signals. The MCU is a central controller with the following functions: being capable of receiving signals from a pulse metering module, calling stored instructions, and generating and storing gas usage amount detail data under the control of the instructions. The gas meter can generate the gas usage amount detail data in the meter, can charge in a system after acquiring the detail data, and achieves the multistep charging and the time-sharing charging for gas.

Description

technical field [0001] The invention relates to a gas meter. Background technique [0002] At present, the metering and charging methods commonly used in the city gas (pipeline gas, natural gas, etc.) industry are as follows: 1. The mechanical gas meter is used as the metering tool, and the meter is read manually. The difference between the meter reading and the meter reading this time, as the usage amount, multiplied by the unit price, can form the billing amount of this time; 2. The prepayment method using IC card gas meters for metering and billing. That is to say, the pre-stored gas consumption is automatically deducted when the unit deduction amount is reached. That is, when the user uses gas to reach a unit deduction amount, the gas meter will automatically subtract a unit deduction amount from the pre-stored value. Until the pre-stored value is exhausted; 3. Using remote gas meters for metering and billing. That is to use the mechanical gas meter as the base meter...
