[Meter's latest patent] Internet of things smart meter with ladder pricing function

Content Description

The present invention relates to a water meter. More specifically, the present invention relates to an IoT smart water meter with a ladder pricing function.

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 IoT smart water meter with a ladder pricing function aiming at the above insufficiency in order to solve the problem in the prior art that the IoT smart water meter does not have the function of ladder pricing, similar to the time and control end of the product table. There are differences, resulting in technical problems such as pricing and price adjustment are not uniform.

In order to solve the above technical problems, the present invention adopts the following technical solutions: The invention provides an IOT intelligent water meter with ladder pricing function, comprising a ladder pricing main control module, a wireless communication module, a clock chip and a water flow measuring device The main control module of the ladder pricing is respectively connected with a wireless communication module, a clock chip, and a water flow measuring device. The main control module of the ladder pricing includes a processor and a memory, and the processor is connected with a memory; and the wireless communication is performed. The module passes through the internet of things access control terminal, and is used to receive the price instruction of the control terminal through the internet of things and transmitted to the processor; the water flow measurement device is used to transmit the flow count result to the processor; and the processor is based on the price plan. The duration of the cycle, recording the cumulative amount of water used for the duration of the cycle and storing it in memory.

The processor is configured to store the price plan in the price plan instruction in a memory, and the processor can synchronize the clock information of the clock chip with the time of the control end, so that the time of the clock chip is consistent with the time of the control end; according to the price plan The initial price ladder in the price calculation of the counting result; and the processor also reads the accumulated water consumption in the duration of the cycle in the memory, compares it with the upper limit value of the initial price ladder, and judges the accumulated water consumption in the duration of the current cycle. Whether to reach 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 performed on the count result according to the current price ladder; It is used to judge 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 judgment result is yes, the current cycle is considered to be completed, the accumulated water consumption in the cycle duration in the memory is cleared, and the reset is performed. Initial price ladder pair count to price plan If prices performed; otherwise proceed to step prices according to the counting result of the current price.

As a preference, a further technical solution is: the wireless communication module accesses the Internet of Things through any one of a Wifi signal, a GPRS signal, and a Zigbee signal. The price plan includes a current price plan and a new price plan. The current price plan and the new price plan are respectively stored by the processor to the memory for reading the execution time of the new price plan by the processor and the clock chip. The current time is compared to determine 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, otherwise the current price plan is continued to be executed.

The memory also stores recharge amount data, which is used by the processor to calculate the price of the counter result according to the current price step, and after the calculation result is obtained, the value of the calculation result is subtracted from the recharge amount data in the memory. 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. 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 condition of the start month of the cycle is continued to be determined 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.

The price plan instruction also includes clock information for the processor to synchronize the clock information to the clock chip. The manner in which the processor synchronizes the clock information of the clock chip with the time of the control end is that the control end periodically sends clock synchronization instructions to the data concentrator in the Internet of Things, and the data concentrator continues to run time according to the current clock information as a starting point, and periodically The clock synchronization instruction is sent to the wireless communication module, and the processor synchronizes the clock information in the clock synchronization instruction to the clock chip.

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 be used to determine whether to start the next price ladder for billing in real time by the table processor according to the accumulated water consumption during the cycle duration. The current cycle can be judged according to the end time of the cycle in the price plan. In addition to the time synchronization, the entire process is completed at the table side; meanwhile, the present invention provides a smart meter with a ladder pricing function and has a simple structure in the Internet of Things. In addition to realizing the pricing of the stairs, it also ensures the consistency of time between the table and the control end, and can be improved based on the existing intelligent water meter, and has a wide range of applications.
