The system to monitor temperature of granary using narrowband internet of things (IOT) is disclosed in the present invention.
The invention is realized as follows: a temperature monitoring device based on a narrow-band Internet of things granary, including two or more temperature monitoring units and a narrow-band Internet of things wireless communication node;
One of the narrowband IoT wireless communication nodes is electrically connected to a plurality of the temperature monitoring units; the narrowband IoT wireless communication node includes a control module, a power management module, a narrowband IoT wireless communication module, and a storage module. The power management module Respectively connected with the control module, the narrowband Internet of Things wireless communication module, the storage module and the temperature monitoring module, and the control modules are respectively connected with the narrowband Internet of Things wireless communication module, the storage module and the temperature monitoring module;
The power management module is used to control the output voltage of the power supply and supply power to the module and the temperature monitoring unit of the narrowband Internet of Things wireless communication node.
Further, the narrowband Internet of Things wireless communication module uses a narrowband Internet of Things communication technology, and its structure includes a Quectel BC95 chip, and the Quectel BC95 chip is used for signal processing and data transmission.
Further, the number of the temperature monitoring units is more than four.
Further, the storage module is an SRAM storage module, a DRAM storage module or an SDRAM storage module.
Further, the control module is a low-power single-chip microcomputer.
Further, it also includes a monitoring pole, and the narrowband Internet of Things wireless communication node is arranged at one end of the monitoring pole.
Further, a handle is provided at one end of the monitoring rod, and the handle is provided at the same end as the wireless communication node of the narrowband Internet of Things.
The invention has the following advantages: different from the existing granary temperature monitoring device, the energy loss is large, and the signal transmission is unstable. This technical solution is based on the narrowband Internet of Things granary temperature monitoring device, through the narrowband Internet of Things (narrowband NB-IoT) technology for signal management, storage and transmission, and its effects have low data rate transmission, large-scale terminal number management and a large range Signal coverage and other advantages. Narrowband NB-IoT has good signal coverage performance and can efficiently transmit data; its uplink gain is higher than other existing wireless communication technologies; its energy consumption is much smaller than other existing wireless communication technologies, and its battery life is longer than 10 years; reading time is less than 1 second, authorized spectrum, service quality can be guaranteed, transmission distance is greater than 10 kilometers; user fees are low; its information transmission security is stronger than Wi-Fi and other wireless communication technologies, and it can prevent the leakage of public information.
One narrowband IoT wireless communication node is connected to multiple temperature monitoring units to save the cost of using multiple wireless communication nodes. The DS18B20 temperature sensor is used to automatically collect the temperature in the granary. The DS18B20 temperature sensor is distributed on the monitoring rods at equal intervals to realize the temperature collection of grains of different depths and the even distribution of multiple monitoring rods in the granary, making the temperature The collection is more accurate. At the same time set the temperature value of the granary, lower than the set temperature value, the narrowband IoT wireless communication node will transmit the temperature information and serial number to the narrowband IoT wireless communication base station at regular intervals, and the base station then transmits the information to the control center.
When the temperature value exceeds the set value, the NB-IoT wireless communication node immediately transmits the information to the NB-IoT wireless communication base station, and the base station then transmits the information to the control center. The control center will send out an alarm signal and control the centrifugal fan, exhaust window and air conditioner to cool down to keep the temperature within the set range. At the same time, the power management module can be used to reasonably control and deliver power to ensure the reasonable use of battery power without connecting to the mains, which improves its mobile performance. At the same time, it can also provide external power for the temperature monitoring unit.
