NB-IoT-based wide-area direct-connecting online monitoring system

Abstract

The present invention provides a Narrow Band Internet of Things (NB-IoT)-based wide-area direct-connecting online monitoring system, which specifically comprises a measurement module, a collection andprocessing module, a NB-IoT data remote transmission communication module, a power supply module, a server terminal and a viewing terminal, wherein the measurement module measures physical parameters, the collection and processing module receives the data of the measurement module, the NB-IoT data remote transmission communication module remotely transmits the data to the server terminal, and a user accesses the server terminal through the viewing terminal so as to real-timely acquire the measured data.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and municipal energy, and specifically relates to a wide-area direct-connected online monitoring system based on the cellular narrowband Internet of Things (NB-IoT). Background technique [0002] In the fields of heating and air conditioning, water supply and drainage, etc., the pressure, temperature, flow and other parameters of the traditional water system are mostly measured by mechanical instruments, which realize the reading, collection and recording of measurement data through dial display, manual reading, and paper and pen recording. , and the operating personnel then manage the operation of the system according to these read or recorded data. With the development of automatic control technology, automatic instruments are used to measure and collect parameters such as pressure, temperature, flow and water quality in many heating and air-conditioning or water supply and draina...

Problems solved by technology

On the one hand, this method enables real-time data collection, which is a necessary link for the system to realize self-control; Without exception, power supply is required, which has become an important restrictive factor for its wide application. Either it should be placed near a power supply that is convenient for power connection, such as in the water supply station of a thermal station; or it will cost a lot to install a separate line for power supply, which is relatively expensive. Large, even limited by site conditions can not be realized; or set battery power and use Zigbee, Thread and other low-power chip networking, but these chip solutions can not directly achieve long-distance communication, and the system composition is complex, if directly using mobile phones Chip (DTU) communication, battery power and life are limited, regular replacement is cumbersome and costly

With the demand for the development of smart cities, the real-time monitoring and control requirements of municipal systems such as heating and air conditioning, water supply and drainage in the future will increase. It is necessary to install relevant instruments to realize online monitoring. Obviously, the existing solutions are difficult to meet its large-scale application and development.
