Method for remotely and dynamically monitoring electric energy metering load

Abstract

The invention discloses a method for remotely and dynamically monitoring electric energy metering load. The method comprises the following steps of: (1) modularly encapsulating data according to the difference of operation frequency and monitoring authority to build a header, a CRC and a split key which correspond to the data; (2) transmitting an encapsulated data packet to a background processorauthorized by an allocation level through the internet, wherein the background processor splits the modular data packet according to the authority of an operation key, the verification of the data CRC and the verification of the split key, and performs the CRC verification and the fault tolerance processing on the split data; (3) building a matched data processing mode to correspond to the data packet one-to-one according to the operation frequency; and (4) processing, backing up and reporting abnormal data in a way of combining an arbitrating mechanism with self-healing capacity. By the method for remotely and dynamically monitoring the electric energy metering load, the management and the use of the electric energy metering load are more accurate, quicker and more effective, and the accuracy and the justification of electricity user checking are guaranteed.

However, the above two disclosed utility models do not involve the method of remote dynamic monitoring of electric energy metering loads

The Chinese invention with the publication number CN1690718A discloses a monitoring method for electricity balance in a power supply system, which is used for monitoring the input and output high-voltage electric energy metering devices of transformers, substation busbars, and local area networks in the power system. The monitoring of the balance of the input and output power of the power supply system, but the above-mentioned technical solution is only used for monitoring the high-voltage metering device, and does not involve the method of remote real-time monitoring of the dynamic load characteristics of the electric energy meter. So far, there is no disclosure at home and abroad that can meet the relevant requirements , An efficient and reliable method for remote and dynamic monitoring of electric energy metering loads, especially for electric energy meters embedded in the Linux operating system
