Water source remote monitoring system based on NB-IoT

Abstract

The invention provides a water source remote monitoring system based on NB-IoT. The water source remote monitoring system comprises a monitoring controller, a data acquisition device and a remote monitoring center, wherein the data acquisition device is connected with the monitoring controller; the remote monitoring center is connected with the monitoring controller through a cloud platform; the monitoring controller is connected with the data acquisition device through the wire communication of an RS-485 serial port or the wireless communication of a 470 MHz module; the monitoring controlleris communicated with the cloud platform through an NB-IoT wireless network module to realize wireless remote reporting of the acquired data; and the remote monitoring center accesses to the cloud platform through a TCP / IP network to obtain the acquired data reported by the monitoring controller. The water source remote monitoring system realizes on-line precise monitoring of water sources well, aninformationalized and intelligentized monitoring managing platform is established, and meanwhile, the engineering construction investment cost, the wireless communication power consumption cost and the data transmission flow cost of water source monitoring, operating and managing are greatly reduced.

Description

technical field [0001] The invention relates to an NB-IoT-based remote monitoring system for water resources. Background technique [0002] In the prior art, the wireless data transmission of the water resource remote monitoring controller adopts GPRS, CDMA, and 4G wireless network transmission, and the GPRS, CDMA, and 4G wireless network communication modules consume a lot of power, and usually need an external 220V mains and a transformer to convert it into a DC power supply , or an external solar power generation device to supply power to GPRS, CDMA, and 4G wireless communication modules. The investment in mains power supply or solar power generation devices in project construction is relatively high, and the communication module’s energy consumption costs are high during operation. The wireless communication module needs to pay a fixed traffic usage fee, and the usage cost is high. NB-IoT is a low-power wireless communication module, which is powered by a lithium batter...
