Monitoring Information

The detection of nitrate pollutants is a widely used strategy for protecting water sources. Although ion-selective electrodes (ISEs) have been considered for the determination of ion concentrations in water, the accuracy of ISE technology decreases owing to the signal drift and decreasing sensitivity over time. The objectives of the present study were: (1) to develop an online water monitoring system mainly consisting of an Arduino board-based Internet-of-Things (IoT) device and nitrate ISEs; and (2) to propose a self-diagnostic function for monitoring and reporting the condition of the ISEs. The developed system communicates with the cloud server by using the message queuing telemetry transport (MQTT) protocol and provides monitoring information through the developed cloud-based webpage. In addition, the online monitoring system provides information on the electrode status, which is determined based on a self-diagnostic index (SDI, with a range of 0–100) of the electrode drift and sensitivity. The diagnostic method for monitoring and reporting the electrode status was validated in a one-month-long laboratory test followed by a field test in a stream near an agricultural facility. Moreover, a self-diagnostic index (SDI) was applied in the final field experiments with an accuracy of 0.77.

In order to increase the management efficiency and decrease the maintenance costs in the traditional dust monitoring system, a novel real-time remote monitoring system using the Internet of Things and cloud server is proposed in this paper. The system includes several sensor nodes, a sink node and Cloud Server. The high-precision dust probe, temperature and humidity sensors, water flow sensors and hydrogen transmitters are integrated together into a sensor node to access the metal polished environmental information. Then, the collected information is transmitted to sink-node using the 2.4G wireless network. The sink-node uploads data to the Cloud Server through the 4G network and TCP Socket. Based on the Browser/Server (B/S) model, a remote monitoring system is developed by using Tencent Cloud Server, C# language, and SQL database. As a result, the on-site metal polishing environmental information is obtained via the App and Web page.

Monitoring Information

Based To solve the problem of incomplete monitoring information,single function and low extensibility of public bus monitoring system,a remote digital monitoring system of public bus based on embedded platform is designed. Bus stop announcer,CAN controller,satisfaction evaluator and other vehicle electronic equipment are integrated into vehicle terminal,which collect,transmit and feedback real time data such as the location of bus,bus station information,running state parameters,satisfaction and vehicle scheduling information. The remote monitoring center receives the data and generates the visualizations webpage at the same time. Bus remote monitoring system is established,and the operation efficiency and security of public bus is improved.After large amounts of running and tests,result of the test indicates the monitoring data received from this system is reliable and stabilized.

The implementation of remote monitor in workshop can improve the production efficiency and contribute to the production management. In this paper, a remote monitoring system of air-jet loom workshop based on B/S structure is designed. The system adopts wireless networking mode in hardware and mainly consists of data acquisition module, database service module and Web service module in software. The data acquisition module is implemented with Visual C++. MySQL is chosen as the database management to design database service module. The Web service module is developed on the platform of asp.net and it is released on the IIS platform of cloud server, so that users can visit the Web site through browser clients. Different yarn materials need to be configured with different parameters. The loom computer can send requests to the cloud server for parameters. The system can analyze the types of yarn materials according to the requests and configure different parameters. This will be quite convenient for workers to change yarn materials.

The article is focused on the data of the carried works on studying biological efficiency of fungi Triazole 50% on sowing the winter wheat against yellow rust as well as on the height, development and fertility of the wheat. On May 5, 2019 from 9 to 10 o’clock under the temperature 21-23 field experiments of Triazol 50% CS manufactured by the firm “Agroximstar” (Uzbekistan) were carried out on winter wheat as a protector of seeds of winter wheat of Pervitsa sort against the disease of yellow rustin the irrigated conditions in an experimental field of the Institute “Istiklal” of Andijan district of Andijan region. The aim of the given research is to study biological-farming efficiency and determination of optimal norms of preparation expenses and to study the influence of fungicide on the height and development as well as on the fertility of the wheat. The received data showed that the preparation Triazole 50% CS effected on the pathogen of yellow rust favorably and besides that it didn’t effect on seed growth and energy of growth negatively.
