Problems solved by technology

[0002] With the acceleration of the intelligent construction of my country's power grid and the development of wireless sensor network technology, there have been many electric energy metering devices and remote meter reading and billing systems based on wireless sensor networks. With the increase in the number of data acquisition devices and coordinators, the collected and uploaded data has become increasingly large, resulting in communication congestion and data loss, which greatly affects the accuracy, real-time and reliability of energy billing. On the other hand, due to the current energy meter , The communication between the data acquisition device and the coordinator mostly does not take into account the security of data transmission, and the data is easy to be stolen and tampered with during the transmission process, causing users and power supply units to suffer economic losses

Abstract

A safe and remote wireless meter reading and charging system comprises smart meters, data collectors, coordinators and a management system, wherein each coordinator creates a wireless network with an independent network identity, the corresponding data collectors join the network, each smart meter selects one group of key and encryption algorithm (A) randomly from a key and encryption algorithm matching table, first encryption is performed on power utilization information, a power utilization information frame is generated, the corresponding data collector performs second encryption on the power utilization information frame to generate a new power utilization information frame and sends the power utilization information frame to the corresponding coordinator, and the power utilization information frame is resent if the corresponding data collector receives a resending request frame and analyzes that the network address of the data collector is contained in the frame; the management system monitors a time slot request sent by the coordinators and distributes sending time slots, when the sending time slots are started, the coordinators start to send the power utilization information frames after delaying for a time period and stop sending before the time slots are ended, and the management system performs encryption operation twice on the received power utilization information frames to obtain the power utilization information.

Description

technical field [0001] The invention relates to the field of safe remote meter reading and billing, in particular to a safe remote wireless meter reading billing system. Background technique [0002] With the acceleration of the intelligent construction of my country's power grid and the development of wireless sensor network technology, there have been many electric energy metering devices and remote meter reading and billing systems based on wireless sensor networks. With the increase in the number of data acquisition devices and coordinators, the collected and uploaded data has become increasingly large, resulting in communication congestion and data loss, which greatly affects the accuracy, real-time and reliability of energy billing. On the other hand, due to the current energy meter , Most of the communication between the data acquisition device and the coordinator does not take into account the security of data transmission, and the data is easy to be stolen and tampere...
