The invention provides a grain storage temperature monitoring system and method based on the narrow-band Internet of Things. The grain storage temperature monitoring system comprises two or more temperature monitoring units and a narrow-band Internet of Things wireless communication node, wherein the narrow-band Internet of Things wireless communication node comprises a control module, a power supply management module, a narrow-band Internet of Things wireless communication module and a storage module. According to the technical scheme, signal transmission is carried out through a narrow-band Internet of Things technology, and the grain storage temperature monitoring system has the effects of low power consumption, long node service life, large-scale terminal number management, large-range signal coverage, high information safety and the like. Through a DS18B20 temperature sensor, temperature in a granary is automatically collected, and the narrow-band Internet of Things wireless communication node transmits information to a control side in certain time intervals or when the temperature exceeds a threshold value. When a temperature value exceeds a set value, the control side controls a centrifugal fan, an air exhaust window and an air conditioner to carry out cooling processing so as to achieve a purpose of intelligent control.
Description
technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a system and method for monitoring the temperature of a granary based on narrowband Internet of Things. Background technique [0002] In the existing granary temperature monitoring and control system, the temperature sensor is used to detect the temperature in the granary, and then the detected signal is transmitted to the control terminal through wireless transmission, and then the temperature in the granary is detected. Cool down with fans to keep the temperature in the granary within the specified range. However, the existing communication technologies are wireless communication technologies such as Zigbee technology, GPRS and WiFi. The data accuracy rate of such communication technologies is relatively low, and the power consumption is relatively large. At the same time, its wireless sensor needs to carry an additional battery for power supply. The granary i...
