Cloud Computing and Internet of Things in the Evaluation of Ecological Environment Quality in Rural Tourist Areas in Smart Cities

With the increase of tourist environment, the real-time monitoring of ecological environment has become a concern. This study mainly discusses the application of cloud computing and Internet of things in the evaluation of ecological environment quality of rural tourism areas in a smart city. In this study, the real-time monitoring of the atmosphere, water, and meteorological data is collected through the GPRS data transmission module and then sent back to the local server by the GPRS network, and the obtained non-real-time and real-time data are used to establish the ecological monitoring database, the database analysis of its information, and get real-time data, monthly data, and longer cycle data. In the cloud GIS platform, there are multiple subnodes. The split tasks can be processed by each subnode through a map, and the results after processing can be summarized through reduce, which completes the implementation process of the whole idea of map reduce. Monitoring station management is mainly to establish monitoring stations in rural tourism areas and collect first-hand environmental monitoring data by using temperature, humidity, infrared, ultrasonic, and other sensors and cameras. The monitoring objects are the air quality, water quality, meteorology, etc. of the scenic area, mainly showing the location of monitoring stations and the placement of sensors. At the same time, an LED screen is set at the monitoring station to display the air quality data of the scenic spot. The data content is introduced into the DPSIR model, combined with social and economic data; according to the ecological health grading evaluation standard, the evaluation score and health grade are obtained and the ecological health status of rural tourism area is judged and evaluated. When the amount of data is less than 500 MB, there is little difference between the storage speed of the cloud GIS platform and single machine, but with the continuous increase of the amount of data, the storage speed of the cloud GIS platform is significantly higher than that of a single machine. This study is helpful in improving the ecological environment quality of rural tourism areas.

Mobile intelligent terminal speaker identification for real-time monitoring system of sports training

Mobile intelligent terminal speaker identification for real-time monitoring system of sports training is presented in this manuscript. The purpose of speaker recognition is to use speaker’s voice characteristics to identify the speaker’s identity. No two people in the world have exactly the same voice characteristics, because from the perspective of the human physiological structure, different people’s vocal shapes, throat sizes, and other factors related to pronunciation are different, which makes it possible to recognize speech by speech. From the technology level, the proposed framework contains the four core aspects, namely: speaker identification, motion gesture detection, heart rate detection and breath detection. In the information collection part, we adopt the ZigBee + WIFI wireless transmission, GPRS data transmission and Bluetooth communication joint framework to capture the accurate data to rrealize the dual-network dual-pass function, the TD-SCDMA receiver must also work at the same time when the GSM radio module of the terminal is working. In the speaker identification part, we propose the novel deep neural network framework and revise the architecture. The experiment compared with the other state-of-the-art models have proven the robustness of the proposed framework.

The Establishment of Distributed Photovoltaic Power Station Data Collection System

The massive access of distributed photovoltaic power station poses a great challenge to the safe operation of the power grid, and the real-time and accurate data transmission is the first trouble to be solved. In this paper, through the establishment of distributed photovoltaic power station data collection system, a set of voltage transformer and current transformer are used to collect data on scene, through middle register at the same time guarantee the data synchronization, through the AD converter is converted to a digital signal after through the WiFi or GPRS data transmission based on conditions in the field. A distributed photovoltaic power station in Jincheng area as an example, it represents that the system has a certain advantage in data realtime, accuracy, overcome the previous system synchronization, real-time data transmission and low accuracy of shortcomings, at the same time in many related power grid applications have a certain role in promoting.

Greenhouse monitoring and control applications using Wireless Sensor Networks (WSN) ZigBee modules, GPRS data transmission, and CAN bus communication are presented and classified, highlighting the communication specific benefits. Remote monitoring/command and supervisory control and data acquisition (SCADA) systems are analyzed and classified offering to users the following advantages: local and remote visualizations of process data, access to process set-points, optimal control strategies, database data recording, report generations and alarm management. Image processing is another development direction for greenhouse facilities, with promising results for insect monitoring, chlorophyll content estimation, identification, classification and harvesting of fruits. The analysis and classification in appropriate categories of recent contributions, using significant application examples referred in the paper, offers a vision for the greenhouse environment monitoring and control based on modern solutions and technologies, ideas for new applications and relevant research opportunities to optimize the greenhouse processes.

A Survey of GSM Technology to Control Remote Devices

This work describes the different design and implementation of a GSM based remote systems. All existing systems either use GSM or GPRS technologies; however, GSM is the basic way of communication. Due to global GSM roaming facility and good network capability, there is virtually no requirement to build additional network. GSM based SMS services are very cheap and affordable; therefore transmission of data based on SMS in real-time applications has become very popular. GPRS data transmission speed is much faster than normal text message, approx 28 to 32 SMS per/min may be achieve over GPRS. This study explores different tools and technique being used to control communication network through SMS. We also critically review the merit and demerit of various existing solutions. The results of the study are reported in this paper.
