Displacement monitor based on NB-IOT

Abstract

The invention discloses a displacement monitor based on NB-IOT. The monitor comprises a housing, the surface of the housing is provided with a power switch, and the bottom surface of the housing is provided with an NB-IOT antenna; a microcontroller is arranged in the housing; the microcontroller is connected with a signal transmission module, a sensing module, a three-mode positioning module, a timing module and a battery module. The microcontroller is used for receiving and sending a power switch instruction, receiving information of the sensing module, the three-mode positioning module and the timing module and sending alarm information to the signal transmission module. According to the invention, the NB-IoT is constructed in the cellular network; the displacement monitor has the advantages of being wide in coverage, multiple in connection, high in speed, low in cost, low in power consumption, excellent in architecture and the like; the basic requirement for real-time monitoring ofarticles can be met effectively by being combined with the sensing module, the functions of real-time monitoring and alarming, data collection, transmission, low power consumption, full-coverage networking and the like can be realized, and the displacement monitor based on NB-IOT can be widely applied to various fields needing displacement monitors.

Description

technical field [0001] The invention relates to a displacement monitor, in particular to a displacement monitor based on NB-IOT, and belongs to the field of fixed object supervision. Background technique [0002] In daily life, there are a large number of equipment such as unmanned vending machines, beer cabinets, express cabinets, etc., which are often moved or stolen, and the asset owner cannot grasp the status of the assets. Through the method of manual inspection, the accuracy and real-time , cost control aspects, are difficult to meet the demand. [0003] The technical monitoring methods currently on the market mainly include: [0004] 1. Monitoring method based on GPS positioning: that is, the displacement distance is measured by the GPS signal where the item is located, but most of the retail cabinets are indoors, and the equipment cannot work without a GPS signal. GPS accuracy (such as displacement behavior of 10 meters or less) is also too coarse for object moveme...
