The LoRa-based Solution of Trash Can Online Monitoring System Helps the Construction of Smart CityThe LoRa-based Solution of Trash Can Online Monitoring System Helps the Construction of Smart City Background With the rapid growth of urbanization in China, a lot of garbage is generated every day, and garbage bins and garbage stations have become an indispensable part of urban environmental protection management to store garbage and avoid environmental clutter. However, the management of garbage bins and garbage stations has always been a pain point in urban management, and there are mainly the following problems. 1. There are often too many garbage overflows in the garbage cans, resulting in cluttered and scattered garbage, affecting the appearance of the city. 2. The internal temperature of the garbage is too high or there are cigarette butts. It is easy to produce garbage spontaneous combustion, there is a certain fire hazard and endanger public safety. 3. The overflowing state of the trash can mainly relies on manual regular inspections, which cannot be known in time. There is a lag in cleaning, or the trash can is not full or empty, causing the garbage collection and transportation truck to run in vain, wasting manpower and material resources.
The above problems are in urgent need of technical improvement, and the online trash bin monitoring system came into being, which can help city managers to better manage their services according to the waste level and condition of each trash bin. Solutions The garbage bin online monitoring system is a system based on long-distance wireless communication technology LORA, Internet of Things, and big data. It is mainly composed of LoRa sensor, LoRa industrial gateway, garbage online monitoring and management platform, mobile phone APP, etc., to realize the overall monitoring and management of trash cans and the surrounding environment. 1. System functions The overflow state of the trash can is collected in real time through the LoRa sensor built into the trash can lid. Data such as garbage space occupancy status and trash can tilting status are transmitted to the LoRa gateway through the LoRa network, and the trash can data is uploaded to the trash can online monitoring cloud platform in real time through the 4G network. The manager can more intuitively understand the overflowing situation of each trash can through the computer or APP, which is convenient for arranging garbage collection and transportation vehicles or cleaning personnel to clean up, and plan the best recycling route for the garbage collection and transportation vehicles. 2. System advantage
LoRa low power wide area network has the advantages of low power consumption, long distance, anti-interference and so on. Wireless communication is achieved with the lora sensor installed in the trash can through the HKT LoRa gateway, and the collected data is uploaded to the trash can online monitoring center through the 4G network. Managers can directly access the gateway or network server to monitor and manage all data. At the same time, multiple lora sensor data is sent through one gateway, saving 4G traffic fees.
When the garbage bin is full, the LoRa sensor will send data to the HKT LoRa gateway, and the LoRa gateway will then send the information to the online monitoring center. After receiving the information, the management center will conduct garbage recycling according to the location of the garbage bin.
HKT LoRa gateway supports access to online monitoring center and cloud management platform. Through the cloud management platform, unified monitoring of the running status of terminal equipment scattered in different locations can be realized, and the terminal running status and online network status, equipment failure, and traffic usage can be grasped in real time, thereby reducing operating costs. |
