Angle detection intelligent alarm device with dual-mode communication function

Abstract

The invention discloses an angle detection intelligent alarm device with a dual-mode communication function. The angle detection intelligent alarm device comprises an integrated circuit chip, an acceleration sensor, a gyroscope, a power supply module, a charging module, a local area radio frequency communication module and a narrow-band Internet of Things communication module which jointly form the intelligent alarm device. According to the invention, acceleration values and angular velocity values of X / Y / Z direction axis of a monitored object are collected through a gyroscope and an acceleration sensor, a microcontroller calculates the sum of the three-axis data values, and when the rotation angle within a short time is larger than a set safety angle value, it is judged that an alarm situation occurs, so that a door is opened; and a dual-mode communication function is realized in two communication modes of local area radio frequency communication and narrowband Internet of Things, sothat the device has the characteristics of small size, convenience in installation, low cost, low power consumption, concealment, safety and high counter-reconnaissance capability.

Description

technical field [0001] The invention relates to an angle detection intelligent alarm device with a dual-mode communication function, belonging to the field of intelligent security. Background technique [0002] The common smart security devices on the market now include door magnetic alarms, smart cameras, human body induction alarms, etc., which are mainly targeted at anti-theft, but they cannot provide effective, accurate, and timely alarms, and are easy to be discovered and thus affected by decoders. Waiting for interference, the effect is not good. [0003] The main anti-theft alarm equipment currently on the market: [0004] 1. Magnetic door alarm: It senses the position change of the object by sensing the strength of the magnetic field. The door magnetic alarm is usually composed of a switch and a magnet. It must be installed at the crack of the door. When the door is opened, the magnetic force between the switch and the magnet disappears and the alarm is triggered....
