Description

monitor device

The present invention relates to a monitor suitable for industrial environments, especially a monitor that can make the overall volume of the monitor more compact and simple than conventional similar products, and can move multiple photoelectric devices at the same time.

A monitor is an electronic device that can be used to monitor and record live images in real time.

With the progress of society and the development of science and technology, monitors have become a part of daily life. They are widely installed in various places such as traffic intersections, homes, businesses, offices and factories. In addition to preventing potential accidents, they can also Ensure driving safety and environmental monitoring of the site.

Among them, since most of the monitors are installed outdoors, the monitors are exposed to the sun, rain and wind for a long time under long-term use outdoors, and the monitors are prone to corrosion and damage. , dust or other dirt is also easy to accumulate in the gap or lens, which will affect the use of the monitor.

In industrial monitors used in harsh environments, in order to protect the monitor and prolong the service life of the monitor, the known protection method is to set the monitor in a protective case, in addition to preventing the monitor from being directly exposed to the sun In addition to the basic requirements of rain, preventing the monitor from being destroyed or stolen, it is also required to have explosion-proof performance, so as to prevent the monitor from being damaged when a strong explosion occurs in the industrial environment, so as to protect the image acquired by the monitor. .

However, the known protective shells are often fixed structures, and the shells cannot be rotated according to requirements, so that the shooting angle of the camera of the monitor is limited.

In order to achieve a better monitoring quality, some known monitors have a wide-angle camera, a narrow-angle camera and a thermal imager installed in a transparent glass cover. Among them, when shooting at night or in a dark environment, infrared rays can be emitted through the thermal imager to assist shooting; however, when infrared rays are projected onto the transparent glass cover, they will affect the camera's shooting due to reflection and refraction. Therefore, for To reduce the impact of infrared rays on the camera lens, the transparent glass cover will be set to germanium glass; however, the hardness and strength of germanium glass cannot meet the current explosion-proof standards, which limits the position where the monitor can be installed again.
