Electric energy measuring security chip information interactive device

Abstract

The invention discloses an electric energy measuring security chip information interactive device. The information interactive device comprises a chip loading device, a conveying device, a chip reading and writing device and a control system, wherein the chip loading device is used for transferring chips from a loading tube; the conveying device is in docking connection with the chip loading device and is used for conveying the chips; the chip reading and writing device is in docking connection with the conveying device and is used for conducting information interaction on the chips; the control system is connected with the chip loading device, the conveying device and the chip reading and writing device. The information interactive device controls the chip loading device, the conveying device and the chip reading and writing device to act in sequence through the control system to enable the devices to cooperate to complete information interaction of the electric energy measuring security chips and can achieve automatic loading, automatic conveying and automatic reading and writing of the chips to make a chip information interaction working assembly line operate without manual chiptaking, conveying, reading and writing. The labor intensity is reduced. The labor cost is saved. The production efficiency is improved. Moreover, the electric energy measuring security chip information interactive device implements automatic operation to enable the product quality to reach uniformity. The yield is increased.

Description

technical field [0001] The invention relates to the technical field of automation equipment, and more specifically, relates to an information interaction equipment of a safety chip for electric energy metering. Background technique [0002] As a security protection in the form of hard encryption, security chips can implement security functions such as data encryption and decryption, identity authentication, and MAC verification. Therefore, power grid companies have embedded security chips into smart meters to improve the security of smart meters. In order to ensure the safety and stability of the entire electric energy metering system, before the security chip is embedded in the smart meter, it is necessary to write the core key information and establish a file structure, so as to realize the legality verification of the source of the chip. [0003] In the prior art, when writing the core key information to the chip and establishing the file structure, the manual operation o...

[0004] However, it takes about 60 seconds to read and write a chip by using the above-mentioned manual operation to interact with the chip. According to the calculation of eight hours of normal work by a single person, the daily production capacity is only 480 pieces, and the reading and writing efficiency is low.

However, due to the large number of power grid users, the large number of smart meters installed and used, and the large demand for security chips, the traditional manual operation method is difficult to meet market demand.
