Industrial explosion-proof human-computer interface

Abstract

The invention discloses an industrial explosion-proof human-computer interface, which comprises an explosion-proof upper cover and an explosion-proof tank. The explosion-proof upper cover comprises anexplosion-proof upper shell, a capacitive touch screen, explosion-proof tempered glass, a display screen pressing frame, and a display screen. The explosion-proof tank comprises an explosion-proof lower shell, a Zener safety barrier, a computer main board, a display screen backlight panel, a touch screen controller, and an explosion-proof cable gland. The industrial explosion-proof human-computerinterface is compact in structure, excellent in explosion-proof performance, convenient to mount and operate, and small in size, can be arranged on the production site with an explosion-proof requirement, can perform data monitoring and equipment control on the site, and can accurately and immediately control various parameters in conjunction with intuitive observation of site equipment. When theproduction is abnormal, an operator can arrive at the site immediately and perform site disposal within prime time, thereby improving the dealing efficiency.

Description

technical field [0001] The invention belongs to the field of industrial explosion-proof technology, and in particular relates to an explosion-proof man-machine interface used in explosion-proof areas in the fields of pharmacy and chemical industry. Background technique [0002] In the field of pharmaceutical and chemical industry, the site environment is complex, there may be flammable and explosive gases (especially in the explosion-proof area), and fire and explosion accidents are prone to occur. All the electrical equipment with explosion-proof properties are placed on the site. Remote control, put the general control interface in the central control room, away from the production site. However, such a distance is relatively long, and monitoring and operation are troublesome. When an abnormal situation occurs and control is required, it needs to go back and forth between the central control room and the site, which cannot achieve timely and accurate on-site control, and i...

Problems solved by technology

However, such a distance is relatively long, and monitoring and operation are troublesome. When an abnormal situation occurs and needs to be controlled, it needs to go back and forth between the central control room and the site, which cannot achieve timely and accurate on-site control, and is not conducive to improving production automation.
