Existing all kinds of electric energy collection systems, low-voltage collecting meter reading system are the Preliminary Applications of user data collection, in default of to collection
Effective analysis and utilization of data so that user side energy information accurate by marketing personnel, comprehensively can not be grasped and used, system
The quick comprehensive demand of modern electric marketing cannot be met.
Sale of electricity company must develop various flexible integration scenarios and be selected for user in sale of electricity side from now on, for example, customize
Change service, power consuming administrative system, with electrodiagnosis and energy management, demand response technology, distributed energy management, electric power property
Deng.This requires electricity consumption data metering module in sides such as electric parameter measurement, energy data metering, load record data time intervals
Face will as far as possible accomplish that data are accurate, packing density is big, transmission is reliable.Intelligent electric energy meter clearly not applys to sale of electricity company and sends out from now on
Used during exhibition.
Furthermore, it is contemplated that when the company of sale of electricity from now on large area installs electricity consumption data acquisition terminal, existing intelligent electric energy meter
High cost, the large area installed maintenance and intelligent electric energy meter is also govern the problems such as changing inconvenient are used.
So, sale of electricity company is badly in need of a inexpensive, convenient for installation and maintenance, readily replaceable and bent suitable for electric load
The measuring terminal and data collection station of line forecasting system and subsequent development.
