Embodiment Construction

[0006] Airtight anti-theft box processing: the bottom of the airtight anti-theft box can be processed with metal plate material, and the inside of the bottom of the airtight anti-theft box is processed with pressure sensor and signal transmitter fixed position parts. The side and top of the box are made of aluminum alloy frame and tempered glass plate through silica gel sealing process to form the main body of the airtight anti-theft box. Then the pressure sensor and the signal transmitter are fixed at the pre-set positions, and the air pressure solenoid valve is installed outside the bottom of the airtight anti-theft box, and the processing of the differential pressure anti-theft alarm system is completed.

Abstract

The invention discloses a differential pressure type anti-theft alarm system, and mainly relates to a remote alarm anti-theft purpose achieved through a differential pressure signal provided by a pressure sensor and a wireless transmission element. The anti-theft alarm system is suitable for occasions such as museums, pawnshops, valuable exhibition and sales, sealed safe boxes and the like. Knownanti-theft system devices all adopt infrared remote anti-theft alarm systems, and the alarm systems have the defect that an abnormal phenomenon that foreign matters block infrared rays cannot be identified. In order to overcome the defects of an existing anti-theft system product, the invention provides the differential pressure type anti-theft alarm system which not only can give an alarm remotely, but also can accurately judge the reason why the alarm is generated, and has an anti-corrosion protection function on articles in a box. The system is characterized in that a pressure sensor is arranged in a closed anti-theft box, and when the pressure of gas in the box is changed, a signal transmitter transmits a signal to the signal receiving alarm in a wireless mode to complete an alarm task.

Description

technical field [0001] The invention relates to a differential pressure anti-theft alarm system, which mainly relates to a differential pressure signal provided by a pressure sensor and a wireless transmission element to achieve the purpose of remote alarm and anti-theft. The anti-theft alarm system is suitable for occasions such as museums, pawnshops, exhibitions of valuables, and airtight safes. Background technique [0002] At present, the known anti-theft system devices all adopt infrared remote anti-theft alarm system, and its defect of this alarm system is: the definition of the abnormal phenomenon that the foreign object can not be identified to block the infrared ray. Contents of the invention [0003] In order to overcome the defects of existing anti-theft system products, the present invention provides a differential pressure anti-theft alarm system, which can not only remotely alarm, but also accurately determine the cause of the alarm. [0004] The technical s...
