Safety type industrial monitoring unit

Abstract

The invention relates to an industrial monitoring unit, and in particular relates to a safety type industrial monitoring unit which comprises a liquid crystal displayer, wherein a touch screen is arranged in the front of the liquid crystal displayer; the liquid crystal displayer and the touch screen are connected with a CPU (central processing unit); the CPU is connected with an internal memory and a program memory; a PLC (programmable logic controller) communication interface is connected with the CPU through a peripheral communication module; a video camera is connected with the CPU through a picture processing module; and the CPU is connected with an encryption device. When the safety type industrial monitoring unit provided by the invention needs to modify the operating conditions of scene equipment, the operating conditions of the scene equipment can be modified through the authorization of the encryption device, thereby enhancing the safety.

Description

technical field [0001] The invention relates to an industrial monitor, in particular to a safe industrial monitor. Background technique [0002] With the development of industrial automation, automation systems and automation equipment based on PLC, single-chip microcomputer and other equipment are becoming more and more popular, covering almost all automation fields. PLC has gradually become the main force in the industrial field because of its strong anti-interference ability, high reliability, high integration, and convenient use. Various monitors for PLC and other industrial equipment have also emerged as the times require, which greatly improves the monitoring of complex industrial sites. Monitoring automation and control convenience. [0003] In the face of complex industrial sites, it is necessary to closely monitor all aspects of the industrial process in order to detect hidden dangers in time and avoid major accidents. In addition, it is necessary to adjust the pro...

Problems solved by technology

[0004] At present, the methods to solve the above problems in the field of industrial monitoring include: a. Run monitoring software on PC to monitor on-site operating parameters, and run video capture software at the same time to monitor on-site conditions; b. Run monitoring software and video software on embedded platforms ; method a obviously cannot meet the harsh industrial environment requirements, the price is high, and the reliability is low

Although the b method can monitor the scene and parameters at the same time, the scene is huge, and it is difficult to capture comprehensive information with a single video acquisition

In addition, because the monitor can realize remote or on-site control of on-site parameters and adjust production parameters, there is a possibility of human factors misadjusting on-site, and the above two methods cannot avoid arbitrary modification by unauthorized personnel during operation. poor security
