Intelligent urban sewage monitoring system based on NB-IoT

Abstract

The invention discloses a municipal sewage intelligent monitoring system based on NB-IoT, and belongs to the technical field of sewage purification, which deploys PH value, turbidity, dissolved oxygen, conductivity, water pressure and other detection units at each joint of a municipal sewage pipe network to systematically manage an intricate sewage city pipe network. Detected data and indexes aretransmitted through the NB-IoT module, so that the power consumption is low, and the cost is low; the intelligent monitoring platform comprises a big data processing algorithm of machine learning. Theurban sewage pipe network is managed in grades; aiming at the problem of massive access in NB-IoT, the invention designs a dynamic priority NB-IoT random access algorithm based on a sewage level fora sewage monitoring system, so that access competition outside a priority group can be avoided, processing equipment with relatively serious pollution can be preferentially accessed, and pollution source aggravation or diffusion is avoided.

Description

technical field [0001] The invention relates to an NB-IoT-based urban sewage intelligent monitoring system, which belongs to the technical field of sewage purification. Background technique [0002] With the acceleration of urbanization and industrialization, the human demand for water resources is expanding at an alarming rate, and the pollution of water resources is also becoming more and more serious. The amount of urban sewage discharge in my country is increasing day by day, and the composition of sewage is becoming more and more complex. Generally, it includes domestic sewage, industrial wastewater and runoff sewage. It will cause irreversible ecological pollution. my country's sewage treatment started late, with a poor foundation and high requirements. Effective sewage treatment and secondary recycling of sewage are very important to the environment and ecology. Considering that the current urban sewage pipe network is intricate and has no rules and regulations in ma...

Problems solved by technology

[0003] NB-IoT (Narrowband Internet of Things, Narrow band Internet of Things) is based on cellular networks and can be directly deployed on existing networks. Both the industrial chain and network coverage have advantages, and are suitable for highly targeted vertical application fields of the Internet of Things. For urban sewage treatment, there has been no research on the application of narrowband Internet of Things to urban sewage treatment systems.
