Content Description
The invention relates to a terminal intelligent water meter management method. More specifically, the present invention relates to a method for implementing remote meter smart meter ladder pricing.
Background of the invention
With the development of society, the use demand of tap water increases year by year. As a result, the National Water Development and Reform Commission will implement a unified deployment of energy price plans. Some water companies will implement a ladder-based price billing operation mode for terminal water meters. However, the current mainstream smart water meters do not have The function of ladder valuation, due to the differences in the time and the control end of some of the similar products on the market, cannot implement a unified price ladder adjustment and price adjustment in the pricing process, which results in inconsistent billing in the operation of the water company. Therefore, it is necessary to study and improve the functions of existing mainstream smart water meters.
Summary of the Invention
One of the objectives of the present invention is to provide a method for implementing remote metering of smart water meters in order to solve the above insufficiency in order to solve the problem that mainstream water meters in the prior art do not have the function of step pricing, and the time and the control end of the similar product table are different. , resulting in pricing and price adjustment is not uniform and other technical issues.
To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for implementing remote metering of smart meter ladders, which includes the following steps:
Step A, the wireless communication module transmits the price plan instruction sent from the control side directly to the table side to the main ladder price control module, and the IC card information exchange module reads the price plan instruction in the IC card and also transmits it to the ladder price main control module. The processor in the main control module of the ladder pricing stores the price plan in the price plan instruction into the memory, and the processor can synchronize the clock information of the clock chip of the front end with the time of the control end, so that the system time of the clock chip and the control end The system time is consistent.
Step B, the water flow measuring device transmits the counting result to the processor in the main control module of the ladder pricing, and the processor records the accumulated water consumption in the duration of the cycle according to the cycle duration in the price plan and stores it in the memory; The calculator calculates the price of the counting result according to the initial price ladder in the price plan; and the processor also reads the accumulated water consumption in the duration of the cycle in the memory and compares it with the upper limit of the initial price ladder to determine the current cycle duration. Whether the accumulated water consumption reaches the upper limit of the initial price ladder, if the judgment result is yes, then the price calculation is performed on the count result according to the next price ladder in the price plan, otherwise the price calculation is performed on the count result according to the current price ladder.
Step C: The processor determines whether the current time is the same as the end time of the cycle in the price plan according to the time in the clock chip. If the determination result is yes, the processor considers that the current cycle is over, and clears the accumulated water consumption during the cycle duration in the memory. , And reset to the initial price ladder of the price plan to calculate the price of the counter result; otherwise, continue to calculate the price of the counter result by the current price step.
As a preference, a further technical solution is: in step A, a price scheme instruction is transmitted between the wireless communication module and the control end through any one of the Internet, an infrared signal, a Bluetooth signal, a Zigbee signal, and a radio frequency signal.
A further technical solution is: the price plan in step A includes a current price plan and a new price plan, and the current price plan and the new price plan are respectively stored by the processor into the memory, and the processor reads the new price plan. The execution time is compared with the current time in the clock chip to judge whether the current time satisfies the execution time of the new price plan. If the judgment result is yes, the current price plan is replaced with the new price plan and executed, and if not, the execution continues. Current price plan.
In the step B, the processor calculates the price of the counting result according to the current price ladder, and after obtaining the calculation result, the calculation result is subtracted from the charging amount data in the memory. The processor in step B simultaneously records all the accumulated water consumption and the accumulated water consumption for the duration of the cycle and stores it in the memory, and the processor reads from the memory all the accumulated water consumption and the accumulated water consumption for the duration of the cycle. Output to monitor display.
The method for determining whether the current cycle ends in step C is as follows: the processor first judges whether the current day is the same as the cycle start date in the current price plan according to the time in the clock chip, and if the judgment result is no, continue to press the current The price ladder calculates the price of the counter result. Conversely, it continues to determine whether the condition of the initial month of the cycle is met by the following formula: mod(m+12-M, T)=0.
In the above equation, mod is the remainder function, M is the starting month of any period of the current price scheme, m is the current month of the time of the clock chip, T is the period duration in the current price scheme, and T is 12 The divisor, when the formula is established, considers that the period is over; otherwise, it continues to calculate the price according to the current price ladder.
In step A, the processor synchronizes the clock information of the clock chip with the time of the control end to set the clock information in the price plan instruction, and the processor synchronizes the clock information to the clock chip. In the step A, the processor synchronizes the clock information of the clock chip with the time of the control end: the control end synchronizes the current clock information to the clock synchronizer, and the clock synchronizer uses the internal clock function to take the current clock information as The starting point continues to run, and then the clock synchronization IC card is inserted into the clock synchronizer. The clock synchronizer writes the current clock information during continuous operation to the clock synchronization IC card, and then inserts the clock synchronization IC card into the IC card information exchange module. The read clock synchronizes the clock information in the IC card and synchronizes to the clock chip.
The method in which the processor in the step A synchronizes the clock information of the clock chip with the time of the control end is: the control end periodically sends the clock synchronization instruction directly to the wireless communication module of the table end, and the wireless communication module transmits the clock synchronization instruction to the processor The clock synchronization information in the clock synchronization instruction is synchronized to the clock chip by the processor.
Compared with the prior art, one of the beneficial effects of the present invention is that the terminal simultaneously synchronizes with the control terminal in the process of communicating with the control terminal, so that the time of the terminal is always consistent with that of the control terminal, so as to avoid the occurrence of both. Time deviation, resulting in pricing and price adjustment is not uniform; and the price plan is set with multiple price ladders, can accumulate water consumption for the duration of the cycle through the table processor, real-time judgment whether to start the next price ladder for billing, also According to the end time of the cycle in the price scheme, it is judged whether the current cycle should be ended. Except for time synchronization, the entire process is completed at the table side; meanwhile, the method for implementing remote metering of the smart water meter ladder provided by the present invention has simple steps. The realization of the ladder pricing also guarantees the consistency of time between the table and the control end, and can be implemented based on the existing smart water meter, and has a wide range of applications.
