Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The explosives production line or the emulsion explosives mixing vehicle monitors the production site data through the host computer. Such as figure 1 As shown, detection devices such as vibration sensors, temperature sensors and flow meters are set in the explosives production monitoring system to collect production data in the explosives production system and upload the production data to the PLC device. The PLC device controls the state, flow and temperature of the equipment in the production line. The upper computer realizes the system monitoring function through the PLC device, and monitors the production status. For brevity, figure 1 Only one PLC device is shown in the figure, but this does not limit the scope of the present invention. In the actu...

Abstract

The invention discloses a method for detecting the information security of a PLC in an explosive production system. The method comprises the steps of simulating an upper computer to generate a pseudo control message and send the pseudo control message to a PLC device in the explosive production system in a transmission and reception testing mode; acquiring response information which is fed back by the PLC device in the explosive production system for the pseudo control message; and judging whether the PLC device has a security hole or not according to the response information and an expected operation result of the pseudo control message. The method disclosed by the invention provides multi-angle reference for security detection for data uploaded by the PLC, security holes of the PLC information can be discovered quickly, and a targeted solving direction is provided.

Description

technical field [0001] The invention relates to the field of information safety detection in the civil explosive industry, in particular to a method for detecting the safety of PLC information in an explosives production system. Background technique [0002] The products of the civil explosive industry are highly dangerous explosives, and safety accidents occur frequently. In order to improve the efficiency and safety production level of the civil explosives industry, the state vigorously promotes the technology of industrial explosives mixed loading vehicles. Industrial explosives mixing trucks have high production efficiency, good adaptability, and strong mobility, but they are difficult to monitor, and it is easy to conceal and omit the explosives output. In the prior art, an industrial explosive mixing vehicle has been used, which greatly reduces the transportation and storage costs of the industrial explosive. However, the existence of under-reporting and omissions ca...
