Four-Faith NB-IoT-based Intelligent Garbage Bin Networking Solution

Introduction
The traditional garbage collection method has many disadvantages, such as large quantities, wide distribution, high labor cost, and some garbage collection points are remote, requiring a lot of manpower and material resources. In addition to causing serious waste of resources, there are many shortcomings in real-time, accuracy, and applicability. If the use of garbage stations could be monitored in real-time, health management departments could arrange personnel for operations more reasonably.

With the increasing development of urban residential construction and rural small-town construction, the distribution of garbage points is increasing, and the garbage collection system of urban health departments has become more complex. How to collect garbage reasonably and accurately has become an urgent problem to be solved. Understanding the use of garbage station is a crucial key, so remote data collection has become an important part of the garbage system. Wireless transmission solutions are essential. In recent years, with the development of NB-IoT network technology, this technology can be used to efficiently implement remote garbage monitoring systems, which not only have broad coverage, low communication costs, and efficient, real-time remote data reading, but also improve the planning of the health management system for recycling stations and solve the problem of scattered placement that is difficult to manage.

Solution Introduction
The remote supervision solution for intelligent garbage bins in smart cities fully utilizes the new generation of high-tech technologies such as wireless IoT, cloud computing, and mobile internet to provide society with a fast, accurate, and convenient detection system. Through wireless NB-IoT technology, data from infrared sensors, mist temperature sensors, smoke sensors, odor sensors, and other sensors can be transmitted to the WEP service system or mobile APP system in a timely, fast, and accurate manner. Relevant personnel can be notified to handle situations such as full garbage bins or fires in garbage bins, greatly saving labor costs and addressing a series of environmental and sanitation issues. The wireless intelligent garbage system is implemented by NB-IoT technology for ultra-long-range wireless data transmission and can easily receive and send information. It consists of "one platform, countless nodes", that is, one service management platform and countless intelligent garbage bins.

Topology

Terminal layer: 
A NB-IoT terminal with sensors is installed in the trash can. The NB-IoT terminal uses NB-IoT technology to directly transmit data to a remote cloud server through UDP protocol. When the management personnel receive the data, they can arrange personnel to handle the garbage. 
Implementing business functions: garbage alarm, temperature alarm, heartbeat function, etc. 

1.Garbage alarm:
The device periodically collects the garbage capacity in the trash can and reports it to the platform and notifies relevant personnel to handle the garbage when the garbage capacity exceeds the set value, achieving rapid and timely response. 

2.Temperature alarm: 
The device periodically collects the temperature in the trash can, reports it to the platform and notifies relevant personnel to handle the garbage when the collected temperature exceeds the set value, achieving fire prevention purposes. 

3.Heartbeat function: 
The device can be set to report a heartbeat packet at regular intervals (default is once every hour), which includes the device's battery voltage and operating status, and can be used to determine whether the device is operating normally.

Network layer:
NB-IoT is an emerging technology in the IoT field, which supports low-power devices to connect to wide-area cellular networks, also known as Low-Power Wide-Area Network (LPWAN). NB-IoT features low cost, low power consumption, wide coverage, and large-scale connection.

Platform layer: 
It realizes personnel login management, real-time monitoring, data analysis, system event management, personnel management, etc., which can display information quickly, timely, and accurately and push relevant information to responsible personnel, achieving timely garbage handling.

Application layer: 
The mobile app client supports mobile remote monitoring of all alarm information and processing functions.

Solution Value:

Smart management, cost-saving
Simple management: Real-time and stable wireless intelligent data collection saves manpower and management costs.

Quick garbage disposal effectively alleviates the impact of garbage on the environment and daily life.
