Research on a kind of intelligent garbage bin combined with solar street light
Published in Lin Liu, Automotive, Mechanical and Electrical Engineering, 2017
The sensor nodes collect data through the integrated sensor module on a node, and these data are then transmitted over the network to the coordinator node. The coordinator node is responsible for collecting data transmitted over the network, and sending the data directly to the host computer through the serial port or through the network to achieve remote data transmission. Then the relevant departments can develop a simple data management centre software through the database technology. After receiving the data from the sensor network, the data centre is capable of completing the analysis and storage of the data (Hai Ma, 2010). After the data are processed by computer, the information platform will launch realtime information to the sanitation workers. With the help of this information, the sanitation workers can decide which trash needs cleaning up, and which does not need cleaning up, eliminating the trouble of performing a daily patrol and improving efficiency.

Although there is a large number of sensor types, only a few are suitable for RTC of drainage systems. These include rain gauges, water level gauges, flow rate gauges, and water quality sensors. In general, requirements include long-term resistance to water and chemicals, the suitability for continuous recording, remote data transmission, long life or continuous energy source, robustness, and reliability.

conditions (seasonal cycle), and "short" acquisition on a trigger basis (records 3'35" long at a sampling frequency of 100 Hz), when the signal, on one of the acceleration channels, exceeds the predefined threshold (meaningful event, e.g. earthquake) either in time or frequency domain. The system is equipped with a router for remote data transmission to the central server of the University of Padova.

The usefulness and stability of the system were verified through field tests and experiments. However, we found that the system is still in its infancy, and can be regarded only as a quasi-real-time system. There is room to further optimize it in terms real-time processing and remote data transmission to satisfy the demands of real-time processing. Although the research here is mainly based on prevalent algorithms and related technologies, we also make major contributions to the relevant areas: (1) We show how to implement the key algorithms and modules mentioned above, e.g. the improved YOLOv4 target detection algorithm and the data transmission module, and how to combine, integrate, and optimize different parts to build an interactive, shared, and quasi-real-time target detection system based on images acquired from UAVs. (2) We provide a complete development paradigm for similar application systems (such as other applications of target detection), where this has guiding significance for research in the area. These contributions can help promote developments in target detection, especially in real-time target detection based on UAVs.

This article describes a low-cost electronic survey meter made locally and composed of microcontroller boards, a DHT11 sensor, a ZP 1200 Geiger-Müller detector, and XBee S2C wireless modules for remote data transmission. In operation, a system consisting of a PC interacting with the XCTU application (installed on the PC) and the XBee S2C receiver module connected to the PC is used to view the data measured in real time by the developed device. This instrument transmit across a range of more than 1200 m in vacuum.[21] The measurements were carried out in confined spaces (dwellings) from January 2 to February 6, 2022 in the city of Yaoundé-Cameroon. The developed device and the reference instrument were deployed simultaneously. The data obtained from the two devices were used to perform a statistical analysis in order to verify the accuracy of the developed instrument. The data obtained from the measurement are also discussed by comparison to the standards of the International Atomic Energy Agency.[22]

The main control station includes a collecting instrument, a battery and a remote data transmission device, which are arranged on the shore to achieve data timing acquisition and remote transmission functions. The water surface electrode is composed of an electrode cable, a power cable and a floating ball, and monitors the mixing and diffusion processes of the freshwater after being discharged into the sea. When being laid, cable ties are used to fix the electrode cable to the power cable and to arrange the float ball at intervals of 5–10 m. The wire block is connected to the sea bottom with a rope to fix the electrode system, and a buoy is placed to mark the position of the joint. The underwater electrode system is also composed of an electrode cable and a power cable to monitor the brackish water exchange process in the sediment layer. When the tidal flat area is laid with cables, they are directly buried at a depth of 20–30 cm; the water part is directly laid on the seabed surface and is fixed by the raft block at intervals of 5–10 m. The electrode system is usually laid on the shoreline slope, or it can be laid out in parallel according to the monitoring needs.
