Ultra-low power consumption soil near-earth wireless sensor system based on paas platform

Abstract

The invention discloses an ultra-low power consumption soil near-ground wireless sensing system based on a PaaS platform and a use method thereof. The system includes several sensors installed in the soil, and a signal transceiver module is arranged in the sensor, and the signal transceiver module passes LoRa The wireless communication sends the signal to the LoRaWan gateway, and the LoRaWan gateway is connected with the PaaS platform and the user group in turn; the sensors include soil moisture sensors, soil salinity sensors, and rainfall sensors. An ultra-low power consumption soil near-earth wireless sensor system based on the PaaS platform of the present invention enables the sensor nodes to have ultra-low power consumption, which meets the requirement of a single battery for a single power supply to maintain the node for a long time; integrates LoRa communication technology to build an ultra-low Power consumption, long-distance transmission node network, give full play to the economic value of existing sensors.

Description

technical field [0001] The invention relates to an ultra-low power consumption soil near-ground wireless sensor system and a use method based on a PaaS platform, and belongs to the field of soil monitoring. Background technique [0002] With the development of modern sensor technology and communication technology, data acquisition equipment and systems based on various soil near-ground sensors are widely used in the acquisition of various physical and chemical parameters of field soil. These devices or systems are usually deployed in the wild environment. In practical applications, they face the shortcomings of cumbersome wiring, high operating costs, and inconvenient installation and maintenance; Relying on battery power to support long-term field work is not convenient for the construction of long-distance mass connections and application deployment. [0003] For example, in some soil moisture monitoring systems, communication interfaces such as 485 or SDI-12 are used in ...

AI Technical Summary

Problems solved by technology

The communication module is often independent of the sensor device. The power consumption of the communication module can meet the battery power supply, but the sensor device is still based on the traditional application design, and the power consumption cannot meet the long-term battery power supply. A lot of maintenance work, the advantages of LoRa technology are not really reflected

Self-built sensor systems based on private clouds also face high costs for design, installation, deployment, and upgrades, and cannot meet the increasing demand for sensor connection and management requirements for multi-application data and devices.
