An alarm, alarm system and method for monitoring whether a confined space is damaged

Abstract

The invention discloses an alarm, an alarm system and a method for monitoring whether a confined space is damaged. The alarm includes a casing, a displacement detection sensor, a power control unit, a power supply circuit, a wireless transceiver unit, a humidity sensor, and an MCU operation / storage unit ;Through the wireless transceiver unit, the alarm device and the controller carry out wireless two-way communication, so that the alarm device can be completely installed inside the confined space, and the present invention will not destroy the original airtightness of the confined space, and will not affect the opening and closing of doors and windows, and at the same time , by cooperating with a displacement detection sensor and a humidity sensor, the displacement detection sensor is used to monitor whether the protected confined space is displaced or vibrated. When the confined space is found to be displaced or vibrated, the humidity sensor is immediately activated to detect the new relative humidity. On the one hand, it can reduce the power consumption of the equipment, on the other hand, it can effectively avoid misjudgment, and the reliability is greatly improved, thereby bringing convenience to users.

Description

technical field [0001] The invention relates to the technology in the field of alarm devices, in particular to an alarm, an alarm system and a method for monitoring whether a confined space is damaged. Background technique [0002] In contemporary buildings, advanced doors, windows, shop windows or glass are made of double-layer / multi-layer glass, which forms a closed space inside, which can better reduce heat transfer and achieve energy saving and noise reduction. [0003] Between two or more glass plates, there are frames filled with desiccant to form a sealed space; the closed space is usually filled with a mixture of dry air or an inert gas. Shop windows, office building windows, glass doors and windows in office buildings and residential buildings are often damaged by vandalism or intruders. Double / multiple glazed windows and doors are part of everyday life and the cost of repairing, removing and replacing them after damage is considerable. [0004] In order to protec...
