Safety control method applied to monitoring integrated instruction transmission

Abstract

The invention discloses a security control method applied to monitoring integrated instruction transmission. An application platform layer, an acquisition monitoring platform layer and a PLC control module are included, and the security control method comprises the following steps: establishing a security verification mechanism for issuing a control instruction on the application platform layer, and carrying out encrypted transmission on the content of the issued instruction; setting a safety lock mechanism for determining whether a control instruction is issued or not at the acquisition monitoring platform layer; carrying out check code setting on a message before the application platform layer issues an instruction, and carrying out check code proofreading on the acquisition monitoring platform layer; and adopting a handshake mechanism added in the communication process of the application platform layer and the acquisition monitoring platform layer to judge whether an instruction is issued to the PLC control module or not. Different operation mechanisms are arranged on the application platform layer and the acquisition monitoring platform layer, so that safety accidents caused by misoperation, control instructions issued by illegal clients in a simulation manner and instructions cracked after robbery are prevented. Serious damage to social order and public interests is avoided.

Description

technical field [0001] The invention relates to the technical field of monitoring integrated instruction transmission, in particular to a safety control method applied to monitoring integrated instruction transmission. Background technique [0002] With the promotion of smart water conservancy in my country, monitoring integrated command transmission is widely used in the water conservancy industry, mainly involving data collection and remote control of on-site monitoring equipment, including water quality, water level, rainfall, flow, weather, moisture, work conditions, Monitoring of data such as gold knots and automatic control of gates, etc. Monitoring integration instruction transmission mainly includes application platform layer, message middleware, collection and monitoring layer (OPC Client, OPC Server, IO driver), PLC, etc. The instruction transmission process is that the application platform layer sends messages to the message middleware, the collection and monitori...

AI Technical Summary

Problems solved by technology

[0003] The shortcomings of the existing technology are that the application platform layer does not carry out encryption control, which may easily lead to misoperation and issue wrong instructions; the collection and monitoring does not set up a security protection mechanism and legality judgment, which has potential safety hazards; and the instruction is not encrypted and transmitted, which is easy to The communication is hijacked, and the wrong command is issued after the command is cracked.
