Terminal equipment and configuration method thereof

Abstract

The invention discloses terminal equipment and a configuration method thereof. The configuration method comprises that: when the terminal equipment is powered up and started, a processing unit of the terminal equipment executes an initial part BIOS command to initialize a communication port and wait for receiving Tag information; and after the communication port is initialized, an RFID transmission unit reads the Tag information in a valid range and transmits the Tag information to the processing unit of the terminal equipment, and the processing unit of the terminal equipment executes a corresponding rear part BIOS command according to the Tag information for configuration. The method implements hardware configuration and operation authority setting on the terminal equipment in an RFID mode, meets the requirement that different users in an industrial field have different operation authorities on the same terminal equipment and the requirement that different operation modes have different hardware configurations, fully shows the characteristics of no influence of environment, hard damage, low cost, and intensified security of the system.

Description

technical field [0001] The present invention relates to the technical field of industrial automation, in particular to a terminal device and a configuration method thereof. Background technique [0002] With the development of computer information technology and the increasing popularity of computers, and in order to realize industrial automation and refined management, more and more industrial control sites use terminal equipment as the control system, and terminal equipment has become an indispensable part of industrial control. Moreover, different users have different requirements for operating permissions on the same terminal device, and different configuration requirements for different operation modes such as general operation, maintenance, and advanced management. [0003] In order to meet this demand, the Chinese patent No. 200510036827.9 discloses a "computer system and configuration method thereof". The memory device, the complete BIOS instruction of the system is...

AI Technical Summary

Problems solved by technology

[0005] 1) The cost of external memory is high;

[0006] 2) The external memory is electrically connected to the computer, which is easily damaged during the plugging process;

[0007] 3) The external memory is greatly affected by the environment (temperature, humidity, vibration, etc.);

[0008] 4) The security of the external memory is low: the stored key (that is, the rest of the complete BIOS) is easily copied; the interface of the computer connected to the external memory makes it possible to leak information / data;

[0009] 5) The computer BIOS program code is stored in the external memory. To modify settings, permissions, etc., professional software personnel are required to modify the BIOS code, which is inconvenient to maintain
