[Instrument latest patent] IC card smart meter ladder pricing system

Content Description

The present invention relates to a water meter. More specifically, the present invention relates to an IC card smart meter ladder pricing system.

Background of the invention

With the development of society, the use demand of tap water has increased year by year. In response to the unified deployment of energy price plans by the National Development and Reform Commission, some water companies will implement a stepped price billing operation mode for terminal water meters, but currently 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, it is impossible to 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 an IC card smart meter ladder pricing system aiming at the above insufficiency in order to solve the problem that the IC card smart 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 exist. Differences have caused technical problems such as pricing and price adjustments that are not uniform.

To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an IC card smart water meter ladder pricing system, the system includes at least one IC card smart water meter and remote control system, and the remote control system An IC card module is provided for writing a price plan instruction into an IC card by an IC card module by a remote control system; the IC card intelligent water meter includes a ladder pricing main control module, an IC card information exchange module, a clock chip and water flow a measuring device, the ladder pricing main control module is respectively connected with an IC card information exchange module, a clock chip, and a water flow measuring device, and the ladder pricing main control module comprises a processor and a memory, and the processor is connected with a memory; The IC card information exchange module is used to read the price plan instruction in the IC card and transmit it to the processor; the water flow measurement device is used to transmit the water flow count result to the processor; and the processor determines the cycle duration in the price plan. Accumulated water usage for the duration of the recording cycle is stored in memory.

The processor is configured to store the price scheme in the price scheme instruction in a memory, and the processor can synchronize the clock information of the clock chip with the time of the remote control system so that the time of the clock chip is consistent with the time of the remote control system. According to the initial price ladder in the price plan, the price calculation is performed; and the processor also reads the accumulated water consumption in the cycle duration of 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.

The processor is further configured to determine whether the current time is the same as the end time of the cycle in the price scheme according to the time in the clock chip. If the determination result is yes, the current cycle is considered to be completed, and the accumulated water consumption in the cycle duration in the memory is considered. Cleared, 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: the price plan 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 to a memory, and the new price plan is read by the processor. The execution time is compared with the current time in the clock chip to determine whether the current time meets 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, otherwise the current execution continues. Price plan.

A further technical solution is: the memory also stores recharge data, which is used by the processor to calculate the price of the counting result according to the current price ladder, and after the calculation result is obtained, the value of the calculation result is recharged from the memory. Deducted from data. The processor in the ladder pricing main control module also accesses a display for the processor to simultaneously record all accumulated water consumption and accumulated water consumption for the duration of the cycle, store it in memory, and read it from the memory by the processor. All accumulative water consumption and accumulated water consumption for the duration of the cycle are shown on the display.

The processor judges whether the current cycle ends as follows: First, it is judged whether the current day is the same as the cycle start date in the current price scheme according to the time in the clock chip, and if the judgment result is no, the current price ladder pair count result is continued to be continued. The price calculation is performed, and conversely, the following formula is used to continue to determine whether the condition of the starting month of the cycle is satisfied: [0010] mod(m+12-M, T)=0.

Compared with the prior art, one of the beneficial effects of the present invention is that the smart meter of the IC card simultaneously synchronizes time with the remote control system in the process of information exchange with the remote control system, thereby making the smart meter of the IC card always and remotely controlled. The time of the system remains the same, avoiding the time deviation between the two, resulting in inconsistent pricing and price adjustment; and there are multiple price ladders set in the price plan, which can be used by the smart meter processor of the terminal IC card to accumulate water consumption according to the duration of the cycle. It is determined in real time whether to start the next price ladder for billing, and whether the current cycle should be ended can be judged according to the cycle end time in the price plan. In addition to time synchronization, the entire process is completed at the table side; meanwhile, the present invention provides The IC card smart meter ladder pricing system has a simple structure, and it also guarantees the time consistency between the IC card smart water meter and the remote control system in the system, and can be improved based on the existing IC card intelligent water meter. A wide range of applications.
