The price plan command that control end transmits by step S1, communication module is to ladder gas price main control module, by the processor in ladder gas price main control module, the price plan in price plan instruction is stored in storer, and the table end clock information of clock chip can be carried out synchronous with the time of control end by processor, the system time of clock chip and the system time of control end are consistent; In practical application, communication module by mode Access Control ends such as IC-card, radiofrequency signal, internet, infrared signal, Bluetooth signal, Zigbee signals, and then receives the price plan instruction of control end and other instruction of necessity.
Count results is transferred to processor by the counting circuit in step S2, ladder gas price main control module, and by processor according to the cycle duration in price plan, the accumulative gas consumption in the record period duration is also stored in storer; Go out as shown in Figure 1, sensing device can be arranged on table end machinery or digital electronic unit on, such as be arranged on the magnetic part on base table mechanical counter character wheel, magnetic part and counting circuit are responded to and are produced pulse signal, and counting circuit according to setting, can carry out primary electron counting within a recurrence interval;
According to the initial prices ladder in price plan, calculation of price is carried out to count results by processor; Processor reads the accumulative gas consumption in storer in cycle duration, compare with the higher limit of initial prices ladder, judge whether the accumulative gas consumption in the current period duration exceeds the upper limit of initial prices ladder, if judged result is yes, then according to next the price ladder in price plan, calculation of price is carried out to count results, otherwise then continue to carry out calculation of price according to present price ladder to count results; The accumulative gas consumption of aforementioned processor generally in cycle duration reads the accumulative gas consumption in storer in cycle duration when reaching integer;
According to the time in clock chip, step S3, processor judge that whether current time is identical with the period end time in price plan, if judged result is yes, then think that current period terminates, accumulative gas consumption in cycle duration in storer is reset, and the initial prices ladder resetting to price plan carries out calculation of price to count results; Otherwise then continue to carry out calculation of price by present price ladder to count results.Aforesaid period end time refers to that Period Start Time adds cycle duration; The start time in such as cycle is on August 1st, 2015, period end time is after 12 months that start in the cycle, namely the time of end cycle should be on August 1st, 2016, after the aforesaid time arrives, namely the price unit price of initial price ladder is reset to, what use combustion gas carries out charging, starts the circulation of next cycle.
Above-mentioned price ladder can be regarded as the unit price of every cubic metre of combustion gas, multiple different price ladder (1 rank are comprised in a price plan, 2 rank, 3 rank ... N rank) and start time of invoicing periods and cycle duration, different price ladders and different combustion gas charging unit prices, and each unit price is equipped with a higher limit, in this, as the switching condition of multiple charging unit price, such as when the combustion gas use of X unit/cubic meter reaches 50 cubic metres, calculation of price is carried out according to the unit price of Y unit/cubic meter from the use amount of 51 cubic metres of combustion gas, generally, X < Y, namely in cycle duration, the gas quantity used is more, the unit price of combustion gas charging is higher.
Above-mentioned cycle duration is in units of the moon, and 0 represents 1 year, and the moon can be 1,2,3,4,6,12; The start time in cycle comprises the initial moon in cycle and cycle starting date, and the initial moon in cycle starts with 0, and 0 represents January, and 1 represents February, and by that analogy, 11 represent Dec; Cycle starting date with 0 start, 0 table 1 day, by that analogy, can arrange the end of month, the end of month default value 31.
