Big customer charge calculating terminal

Abstract

The invention discloses a big customer charge calculating terminal. The big customer charge calculating terminal comprises a controller, an RS485 communication circuit, an RS232 maintenance circuit, an RTC real-time clock circuit and a key display unit, wherein the controller is connected with the RS485 communication circuit to provide an RS485 communication interface for the terminal; the controller is connected with the RTC real-time clock circuit for providing real-time time for the terminal; the controller is connected with the key display unit; a power circuit provides a power supply for other circuits; the controller is connected with the RS232 maintenance circuit. The big customer charge calculating terminal disclosed by the invention can be used for calculating total electric charges, initial meter charges, electrical degree charges and power factor adjusted electric charges for big industrial users, performing data statistic analysis operation according to a data source in a data memory module, recording electricity utilization habits of the users recently, guiding the users to use the electricity reasonably, and reducing the extra electric charge expenditure.

Description

technical field [0001] The invention relates to a large user fee calculation terminal. Background technique [0002] The scope of large-scale industrial electricity prices refers to those who use electricity as the driving force or use electricity for smelting, baking, welding, electrolysis, and electrification, and whose total transformer capacity is 315 kVA and above. In order to improve the utilization efficiency of electrical equipment and promote the rationalization and fair burden of industrial electricity consumption, all localities implement large-scale industrial electricity price policies for qualified industrial users. [0003] Large-scale industrial electricity charges include basic electricity charges, electricity charges and power factor adjustment charges. Among them, the electric charge charges are divided into lighting charges and power charges. Power factor adjustment charges first need to be calculated based on the read electricity to obtain the power fact...

Problems solved by technology

It can be seen from this that the calculation of large-scale industrial electricity bills is very complicated. Many customers often have doubts about the accuracy of their monthly electricity bills and charging details when they settle electricity bills. Therefore, users will inquire through various channels. The process of calculation and explanation will take a long time for both the user and the power supply department. With the increase of large industrial users, this part of the time will also increase, and the corresponding cost will also increase.

[0004] In practical applications, there are still users who do not have sufficient understanding of large-scale industrial electricity consumption, and have not adjusted according to their own actual conditions in terms of electricity usage reporting, distribution of electricity consumption time, and improvement of power factor, resulting in serious additional expenditures on monthly electricity bills, resulting in waste of funds And it is easy to make users feel afraid of large industrial electricity consumption
