Device capable of indicating current rate electricity price in real time indoors

Abstract

The invention relates to a device capable of indicating the current rate electricity price in real time indoors, which is characterized by comprising a single-chip microcomputer circuit, a red-yellow-green indicator light circuit, a power-off detection circuit, a power supply circuit, an infrared communication circuit, a clock circuit, a memory circuit and a key circuit, wherein the single-chip microcomputer circuit is connected with the red-yellow-green indicator light circuit, the power-off detection circuit, a power supply circuit, the infrared communication circuit, the clock circuit, thememory circuit and the key circuit. The device has the advantages of simple structure, convenient use, off-line operation and visual display, can indicate the current rate electricity price in real time indoors, not only facilitates users to save the electricity expense, but also can meet demand side management requirements for peak shaving and valley filling of power supply management departments.

Description

technical field [0001] The invention belongs to the field of smart grids, and is a device capable of indicating the current rate and price of electricity indoors in real time. Background technique [0002] With the popularization of smart energy meters to thousands of households, rate electricity pricing, also known as peak and valley electricity prices or time-of-use electricity prices, has begun to be implemented on a large scale. Through price signals, consumers are guided to adopt reasonable electricity consumption structures and methods. This active demand side management The method can enable the smart grid to achieve the purpose of peak shaving and valley filling, and can greatly improve the security and load rate level of the power grid. However, there are the following problems in practical applications. First, smart energy meters are installed outdoors, installed on utility poles, building exterior walls, corridors, basements, power distribution rooms, etc., making...

Problems solved by technology

However, there are the following problems in practical applications. First, smart energy meters are installed outdoors, installed on utility poles, building exterior walls, corridors, basements, power distribution rooms, etc., making it inconvenient for residential users to check the current bill of smart energy meters in real time. Rate electricity price; secondly, the parameter setting of tariff rate time period in many areas is complicated, and the rate electricity price is switched once every two hours, and can be switched 5-12 times a day, which is difficult for users to remember

As a result, in the actual application of tariff rates, most residential users still follow their inherent electricity consumption habits without reasonable planning for electricity consumption.

As a result, the power supply management department failed to achieve the purpose of peak-shaving and valley-filling. What's more serious is: the electricity consumption of users is in the high price range of the peak, and the electricity consumption has not changed. The accuracy of meter measurement is questioned and disputed
