[Meter's Latest Patent] Method for implementing the ladder metering of the smart meter of the Internet of Things

Content Description

The invention relates to a terminal intelligent water meter management method. More specifically, the present invention mainly relates to a method for implementing the ladder metering of the intelligent water meter of the Internet of Things.

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 the ladder metering of the smart meter of the Internet of Things in order to solve the above insufficiency in order to solve the problem that the mainstream meter in the prior art does not have the function of ladder 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.

In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for implementing the ladder metering of the intelligent water meter of the Internet of Things, which includes the following steps: Step A: The price scheme of the wireless communication module receiving the control end through the Internet of Things Orders, and the price plan instructions are transmitted to the main control module of the ladder pricing, and the processors in the main control module of the ladder pricing store the price plans in the price plan instructions into a memory, which can be used by the processor to clock the clocks of the clocks Synchronize with the time of the control end, so that the system time of the clock chip is consistent with the system time of the control end; Step B, the water flow measurement device transmits the counting result to the processor of the ladder price valuation main control module, and the processor according to the price plan The duration of the cycle. The cumulative amount of water used for the duration of the recording cycle is stored in memory.

The price calculation is performed by the processor according to the initial price ladder in the price plan; and the processor also reads the accumulated water consumption in the period of the cycle in the memory and compares it with the upper limit value of the initial price ladder to determine that the current cycle continues. Whether the accumulative water consumption in the time reaches the upper limit of the initial price ladder, if the judgment result is yes, the price calculation is performed on the count result according to the next price ladder in the price plan; otherwise the price calculation is continued according to the current price ladder. Step C: The processor judges 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 judgment result is yes, the current cycle is considered to be finished, and the accumulated water consumption in the cycle duration in the memory is cleared. Zero, and reset to the initial price ladder of the price plan, calculates the price of the counter result; otherwise it continues to calculate the price of the counter result by the current price step.

As a preference, a further technical solution is: in step A, the wireless communication module accesses the Internet of Things through any one of a Wifi signal GPRS signal, 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.

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 the same as 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 plan, it can be judged whether the current cycle should be ended. Except the time synchronization, the entire process is completed at the table side; meanwhile, the method for implementing the ladder metering of the intelligent water meter of the Internet of Things 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.
