Museum exhibit protection dimming glass terminal device and system

Abstract

The invention discloses a museum exhibit protection dimming glass terminal device and system. a circuit detection flash lamp which is formed by a phototransistor, an amplification circuit and a comparison circuit is utilized, a microcontroller immediately sends a command to shut down an alternating current power supply utilized by dimming glass after the abnormal strong light is produced, a shutdown signal is transmitted to an alternating current power supply controller through a photoelectric isolation chip, the dimming glass power supply turns off after amplification processing is performed on the shutdown signal through the alternating current controller to enable the dimming glass to be changed into the non-transparent power-off state, a laser projection signal is transmitted from the microcontroller, a laser projection device is directly driven by the laser projection signal after the laser projection signal is amplified through an amplifier to enable the content to be projected onto the dimming glass, and the laser projection signal shuts down through a microprocessor after a short delay prompt to enable the system to be restored into the normal display state. According to the museum exhibit protection dimming glass terminal device and system, the workload of the management personnel is reduced, communication cables do not need to be laid, the response is timely, the operating cost is low, the effect is good, and the popularization value is good.

Description

Technical field [0001] The invention relates to a dimming glass system for protecting museum exhibits, and belongs to the field of electronic technology and information technology. Background technique [0002] The exhibits in the museum are precious and sensitive to strong light. Due to the high color temperature, hard light quality, and strong breadth of the flash, it will cause damage to the exhibits, especially paintings, murals, silk and other cultural relics. The current museum management mainly relies on manpower, and the security guards are responsible for reminding visitors not to use flashlights. During the implementation process, there are problems such as untimely protection, low efficiency, and prone to friction. In today's rapid development of information and technology, such inefficient monitoring methods are obviously out of fashion. [0003] Liquid crystal glass is also called electronically controlled glass, photoelectric glass, and electronically controlled smar...

AI Technical Summary

Problems solved by technology

[0002] The exhibits in the museum are very precious and are very sensitive to strong light. Due to the high color temperature, hard light quality, and strong width of the flash, it will cause damage to the exhibits, especially to cultural relics such as calligraphy, painting, murals, and silk.

At present, museum management mainly relies on manpower, and security guards are responsible for reminding tourists not to use flashlights. During the implementation process, there are problems such as untimely protection, low efficiency, and prone to friction and quarrels.
