Hydrological monitoring device and method based on narrowband Internet of Things (NB-IoT)

Abstract

The invention provides a hydrological monitoring device based on narrowband Internet of Things (NB-IoT), which comprises a front-end multifunctional acquisition circuit (1), an MCU processor system (2), an intelligent strategy uploading processing mechanism (3), an NB-IoT module (4) and a storage unit (5); the MCU processor system (2) reads parameters configured on the storage unit (5) and selectsdifferent front-end acquisition circuits (1) which can be connected with various types of sensors and can be used for hydrological monitoring instruments which are conventionally used at present, theintelligent strategy uploading processing mechanism (3) is a control program stored on the MCU processor system (2), and selects whether to start the NB-IoT module (4) to transmit data or not, when the NB-IoT module (4) does not work, the NB-IoT module (4) is low in power consumption and keeps in a dormant state, and only one lithium battery is required for conventional monitoring frequency for several years. The hydrological monitoring device based on NB-IoT can embody the advantages of the NB-IoT and the measurement data of the sensors is transmitted to a cloud platform or a server throughthe NB-IoT, so that hydrological monitoring can be spread in a large area.

Description

technical field [0001] The invention belongs to the technical field of hydrological monitoring, and is mainly aimed at data collection and transmission of various sensors, such as data collection and remote transmission of water level sensors, rainfall sensors, flow rate sensors, PH value sensors, turbidity sensors, water quality analyzers, etc., specifically relates to A hydrological monitoring device and method based on the collection and transmission of NB-iot narrowband Internet of Things sensor data. Background technique [0002] Hydrological monitoring refers to a complex and comprehensive system engineering that monitors, measures, analyzes and warns of the temporal and spatial distribution and variation of natural water through scientific methods, and is a comprehensive discipline. Before the reform and opening up, data collection in my country was generally manual. After the rapid development of technology in the past ten years, the degree of automation and moderniz...

Problems solved by technology

Relatively speaking, in some relatively remote or other types (water channels, sewage outlets) and other hydrological monitoring points, it cannot be realized due to the limited power supply or telemetry distance. A bigger problem is that the original initial signal output by the front-end of various sensor manufacturers basically has corresponding specifications. , but the data transmission protocols are inconsistent, resulting in the inability to upload data uniformly

At present, traditional monitoring and measuring points are generally in the form of monitoring stations, and GPRS is mainly used for data transmission. Because of its high power consumption, solar energy must be used to supplement electricity.

This makes the whole monitoring station relatively large, especially in remote areas where transportation and installation are inconvenient, and the target of the solar panel battery is too large and eye-catching, easy to be damaged and stolen, and the maintenance cost is high
