Abstract
The invention provides a method for identifying the full-scale jump of active electric measure, which relates to the technical field of an electric meter and solves the technical problem of correctly identifying the full-scale jump of the electric meter. The method comprises the steps that the latest 5 historic active electric values are obtained firstly, a 4-order runge-kutta interpolation method is used for calculating the current active electric theoretical value at the moment, the requirement that the current active electric measure reaches the full-scale jump according to the calculated current active electric theoretical value is, the largest output value of the current active electric meter and the current active electric real-time value which is obtained by real-time collection are judged, the full-scale jump operation of the active electric measure is conducted if the full-scale jump requirement is satisfied, and the current active electric real-time value at this moment is amended. By using the method provided by the invention, mistakes during the full-scale jump of the electric meter can be avoided.
Description
Technical field
The present invention relates to the watt-hour meter technology, particularly relate to a kind of technology of active electrical degree amount full scale redirect recognition methods.
Background technology
Under normal circumstances, watt-hour meter numerical value is that single step increases, and numerical value reaches full scale, and namely during maximum output valve, its numerical value will be again since 0 counting.
When the full scale redirect appears in the active electrical degree amount of watt-hour meter, must be at the maximum output number of this watt-hour meter of active electrical degree numerical value stack that collects, the data that just can not affect electricity are processed.But the situations such as error, communication data interruption, collection value jumping vanishing might appear in the active electrical degree Value Data that gathers, and these situations can cause the full scale redirect of watt-hour meter to make mistakes.
Make mistakes for the full scale redirect of avoiding watt-hour meter at present and also do not have effective method.
Summary of the invention
For the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides a kind of active electrical degree amount of correctly identifying and whether reaches full scale redirect requirement, the active electrical degree amount full scale redirect recognition methods that can avoid the redirect of watt-hour meter full scale to make mistakes.
In order to solve the problems of the technologies described above, a kind of active electrical degree amount full scale redirect recognition methods provided by the present invention is characterized in that, concrete steps are as follows:
