An IoT home security system

Abstract

The invention discloses a home security system for the Internet of Things, which is mainly composed of a fire extinguishing box, a communication module and an external alarm device. The fire extinguishing box includes a cabinet body and a cabinet door, and the cabinet door is hinged on one side of the front opening of the cabinet body by a hinge. Above, the cabinet is provided with horizontal partitions, and the partitions are fixed and connected to the inner surface of the cabinet in the form of welding or bolting; a dry powder fire extinguisher is placed in the cabinet, and the NB-IOT wireless communication in the present invention Compared with the existing common communication modules, the module has low cost and high data transmission speed. At the same time, it can be multiplexed with the existing cellular base stations, so the cost of use is lower. At this time, when the communication module has signal interference, the whole can be Correspondingly realize the alarm, and the external alarm device is relatively independent, and the overall electric control equipment is less, so not only the cost is low, but also the stability is high.

Description

technical field [0001] The invention relates to the field of indoor security, in particular to an Internet of Things home security system. Background technique [0002] The existing indoor small fire extinguishing devices are mostly water valves connected to tap water. Some of the water connection valves use pressure detection modules, and data transmission is carried out in the form of wireless transmission. Since wireless transmission is easily interfered by external signals, when the water pressure is insufficient There may be cases where the alarm information cannot be fully received, which makes it difficult for the inspectors to detect. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems. [0004] An Internet of Things home security system is mainly composed of a fire extinguishing box, a communication module and an external ala...

Problems solved by technology

[0002] Most of the existing indoor small fire extinguishing devices are water valves connected to tap water. Some of the water valves use pressure detection modules and transmit data through wireless transmission. Since wireless transmission is easily interfered by external signals, when the water pressure is insufficient It may happen that the alarm information cannot be fully received, which is difficult for inspectors to detect
