Remote monitoring system

Abstract

The invention discloses a remote monitoring system. The remote monitoring system comprises a sensing layer, a network layer, and an application layer, wherein the sensing layer comprises a power supply unit, a main control unit, and a sub-control unit; the power supply unit is used for providing a power source; the main control unit is arranged by a river and mainly comprises a master controller and an NB-IoT module; the sub-control unit is arranged on a ball screw capable of moving up and down, and mainly comprises a sub-controller; the network layer comprises an internet-of-things platform;the application layer comprises a client and a mobile terminal; the sensing layer and the network layer are in network connection based on the LwM2M protocol; and the network layer and the applicationlayer exchange data through an API (Application Program Interface). Due to the adoption of the scheme, a manager can realize functions such as remote monitoring (of river water quality and the like),sensor fault alarm and remote setting of monitoring parameters through a PC (Personal Computer) and a mobile phone; and the system has the advantages of low power consumption, low cost, stability andreliability.

Description

technical field [0001] The invention relates to the field of ecological environment protection, in particular to a remote monitoring system. Background technique [0002] The traditional river water quality monitoring collection terminal is installed in a fixed position in the river water. Although the river water is diffuse, for some places with complex water environment, deep water area and slow water flow, once the water environment is polluted, due to Different diffusion rates will lead to different degrees of pollution in the upper, middle and lower layers of the river, resulting in inaccurate detection, untimely alarm, and incomplete assessment; at the same time, in the later stage of pollutant diffusion, pollutants are likely to gradually deposit and become rich. Collected to the bottom of the water, if the water quality monitoring collection terminal is installed in the middle and upper layers of the river, once the pollutants are deposited in the lower layer of the ...

[0002] The traditional river water quality monitoring collection terminal is installed in a fixed position in the river water. Although the river water is diffuse, for some places with complex water environment, deep water area and slow water flow, once the water environment is polluted, due to Different diffusion rates will lead to different degrees of pollution in the upper, middle and lower layers of the river, resulting in inaccurate detection, untimely alarm, and incomplete assessment; at the same time, in the later stage of pollutant diffusion, pollutants are likely to gradually deposit and become rich. Collected to the bottom of the water, if the water quality monitoring collection terminal is installed in the middle and upper layers of the river, once the pollutants are deposited in the lower layer of the water, the alarm will be released due to the detection of no pollution, which will seriously damage the ecological environment and threaten people's lives.

[0003] River water quality collection terminals are generally installed at the corners, intersections, and sewage outlets of rivers. For the same river, there are generally multiple monitoring sections. The traditional method is to simultaneously collect water quality status data from multiple sections, that is, each collection terminal It is in working condition for a long time, which often increases the loss of power consumption and shortens the hardware life of each section

For the sensor of the acquisition terminal, long-term work will lead to failure. For the fault detection of the sensor, the traditional solution is to diagnose the fault when the sensor does not return data. If the fault is only detected in this way, the fault will often be missed. The reported situation is that the sensor is faulty but the data exceeds the value but the fault is not detected
