System for measuring and managing electric energy used for agricultural irrigation and drainage

Abstract

The invention relates to a system for measuring and managing electric energy used for agricultural irrigation and drainage, which comprises a prepaid card electricity meter, a meter reader, a card reader, a provincially unified key system, an electricity selling system and a non-contact intelligent CPU card serving as a storage medium. The same type of equipment adopts a unified technical specification and communication interface to ensure inter-equipment communication and realize the function of the system. A PSAM module with a storage key is arranged in the unified prepaid card electricity meter of an electricity selling terminal; and keys in the PSAM module and the intelligent CPU card are used for performing security authentication to realize the high-level management of recharging and avoid the possibility of selling the electricity privately. The unified key system strengthens the security system of the whole system and improves the technology level of preventing electricity stealing. The unified electricity selling system and WEB data representation and data mining technology improve the accuracy, the consistency and the generality of data and provide a reliable data basis for leaders from provincial and municipal top management departments and the unit.

Description

technical field [0001] The invention relates to an electric energy metering management system, in particular to an agricultural drainage and irrigation electric energy metering management system. Background technique [0002] At present, the status quo of agricultural drainage and irrigation electric energy metering management is that each electric card meter manufacturer has its own independent system, and choosing different manufacturers means using different systems. Such as IC card: At present, what users use is IC card, which is provided by various electric energy meter manufacturers. There are various types and cannot be used universally; the sales price of the card is relatively high. Power sales management system: Each manufacturer designs its own power sales software. The actual ideas are not unified, the functions are simple, independent of each other, and the mode is chaotic. Card Writer: The existing card reader is provided by the watch factory and has different...

Problems solved by technology

Such as IC card: At present, what users use is IC card, which is provided by various electric energy meter manufacturers. There are various types and cannot be used universally; the sales price of the card is relatively high

Electricity sales management system: each manufacturer designs its own electricity sales software, the actual ideas are not unified, the functions are simple, independent of each other, and the model is chaotic

Card Writer: The existing card reader is provided by the watch factory with different functions and cannot be used universally

The technical performance and technical parameters of the electric card meter designed by the manufacturer are not uniform, and many functions cannot be realized

Encryption system: At present, the encryption method is determined by the manufacturer. Some manufacturers have defective encryption functions or no encryption functions, and there are certain security issues.
