A Time Synchronization Method for Electricity Collection Terminal Based on Object-Oriented Communication Protocol

Abstract

The invention discloses an object-oriented communication protocol-based time synchronization method for electricity collection terminals, which specifically includes the following steps: S1, the concentrator sends a collection instruction to the electric energy meter to be read, S2, records the time T2 of the electric energy meter clock, S3. Calculate the difference between the clock time T2 of the electric meter and the sending time T1. S4. If the difference between T1‑T2 is within the range of ±10S, directly obtain the electric energy reading W1 at the reading time T2 of the electric energy meter. S5. If T1‑T2 The difference of T2 is not in the range of ±10S, first obtain the electric energy reading W2 at the reading time T2 of the electric energy meter, S6, if the difference is less than 1 / 3 of the electric energy value of the previous meter reading, upload the repair system, the present invention relates to electricity consumption The field of information collection technology. The time synchronization method of the electricity collection terminal based on the object-oriented communication protocol can realize simple and flexible operation through the object-oriented communication protocol, and it is easy to modify the module parameters online. The steps are simple, concise, convenient, and efficient, which greatly facilitates people's Collect electricity.

Description

technical field [0001] The invention relates to the technical field of electricity consumption information collection, in particular to a time synchronization method for a power consumption collection terminal based on an object-oriented communication protocol. Background technique [0002] The user electricity consumption information collection system is through the collection and analysis of the electricity consumption data of distribution transformers and end users to realize electricity consumption monitoring, implementation of ladder pricing, load management, line loss analysis, and finally automatic meter reading and peak-shifting power consumption , Electricity inspection (anti-stealing electricity), load forecasting and electricity cost saving purposes, the establishment of a comprehensive user electricity information collection system requires the construction of a system master station, transmission channels, collection equipment, and electronic energy meters. The ...
