Safety industrial control system with fingerprint encryption

Abstract

A fingerprint encryption security industrial control system, which includes an industrial computer, a fingerprint collection module and an electric lock, the industrial computer also includes a BIOS with a fingerprint processing function, which integrates a standard BIOS, a fingerprint identification module, a fingerprint database and a main management module BIOS, the main management module includes entering the CMOS setting verification module, entering the system verification module, key lock opening module, electric lock control module and authority setting module. The industrial control system of the present invention is owing to adopt fingerprint encryption, enters CMOS setting and system and all will carry out fingerprint safety verification, therefore improves security; In addition because the BIOS of the fingerprint encryption security industrial control system of this system has fingerprint processing function includes key lock and open module Therefore, when the legal user needs to leave temporarily when the industrial computer is running normally, and then continue to operate after returning, he can use the button lock method, so that he does not need to shut down, which is very convenient; because the industrial computer box of the system is also equipped with an electric lock, the The BIOS with fingerprint processing function also includes an electric lock control module, so it can prevent the industrial control chassis from being opened illegally.

Description

【Technical field】 [0001] The invention relates to an industrial control system, in particular to a fingerprint encryption security industrial control system. 【Background technique】 [0002] The industrial control system is mainly used for process control in industrial technological transformation and industrial automation. Building materials, teaching and other fields. [0003] A kind of industrial computer can refer to the Chinese patent that the application number is 02117200.5, the title of invention is dual-bus industrial control machine and its control method, but the industrial computer disclosed in this patent does not adopt the encryption method like most existing industrial computers. At present, fingerprint encryption methods are rarely used on industrial computers, and even if there are applications, they are limited to permission verification such as file opening. That is to say, the entire industrial computer (including hardware and BIOS) has not changed, but a...

Problems solved by technology

The problem in this kind of startup process is: the password verification can be removed by powering off the CMOS, so that the system can enter the normal operation without verification, and there is no real anti-theft and anti-illegal boot function.

In addition, passwords may be leaked, stolen and forgotten.

[0005] In order to prevent the chassis of the industrial computer from being opened illegally, resulting in loss of hardware or information, the usual method is to lock the chassis with an ordinary mechanical lock, but it is difficult to keep the key, and it is easy to lose or imitate; There was a record of opening the box; in addition, when the key custody is handed over, for safety reasons, the lock must be changed, etc.
