Problems solved by technology

[0002] During the working process of mining electrical equipment, the working environment is harsh and the dust is very large. The data information displayed on the ordinary display screen cannot be clearly observed from a distance; in order to grasp the operating status of the equipment, the operator needs to display the corresponding status in real time through the display device and prompt information
During the working process of the equipment, when the user cannot make timely judgments and operations based on information observation, it is easy to cause damage to the main components, or even accidents

Abstract

The invention discloses a mine dot matrix display device. The mine dot matrix display device comprises a control drive board and a dot matrix display screen connected with the control drive board; the control drive board comprises a CPU, a row information drive module and a column information drive module; the row information drive module is connected with the CPU and used for displaying row information, and the column information drive module is connected with the CPU and used for displaying column information. The row information drive module comprises a plurality of first serial shift registers which are connected with one another, and one of the first serial shift registers is connected with the CPU. The mine dot matrix display device is an intrinsic safety type design, is low in power consumption and high in efficiency and can display the operation condition of equipment in real time.

Description

technical field [0001] The invention relates to a display device, in particular to a mining dot matrix display device. Background technique [0002] During the working process of mining electrical equipment, the working environment is harsh and the dust is very large. The data information displayed on the ordinary display screen cannot be clearly observed from a distance; in order to grasp the operating status of the equipment, the operator needs to display the corresponding status in real time through the display device and prompt information. During the working process of the equipment, when the user cannot make timely judgments and operations based on information observation, it is easy to cause damage to the main components, or even accidents. Therefore, in harsh and dusty environments, accurate, clear, and intuitive real-time display of equipment operating conditions is required, so that operators can remotely observe equipment conditions at the operating position. C...
