The device comprises a power supply module for supplying power to the device, a first memory for storing identifying information of a liquefied petroleum gas steel cylinder, a temperature sensor for monitoring a surface temperature of the liquefied petroleum gas steel cylinder and generating a digital signal of temperature information, a first processor connected to the first memory and the temperature sensor and used for generating a first monitoring signal comprising temperature information and identifying information of the liquefied petroleum gas steel cylinder, and a first transmitter connected to the first processor and used for transmitting the first monitoring signal.

Description

Technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a device and system for monitoring liquefied petroleum gas cylinders. Background technique [0002] As an efficient energy source, LPG is widely used in daily production and life. In recent years, accidents of LPG cylinders have occurred from time to time. The main reasons are unqualified cylinders, LPG leakage, high-temperature baking, accidents during transportation, and illegal gas supply. [0003] At present, the safety issues of LPG cylinders mainly rely on the users’ own safety awareness and manual inspections. The reliability is poor. Large-scale inspections require a lot of manpower and material resources, low efficiency and poor real-time performance, and accidents cannot be dealt with in time. . [0004] Wireless sensor network is a self-organizing network, which has the characteristics of flexible deployment, low networking cost, and safe and reliable data transmission...
