Equipment management is one of the key factors of coal mining safe-production, the traditional equipment management methods can no longer meet the real-time and automation needs of modern management. Based on fault diagnosis, sensor network and wireless communication technology, this article proposes a new modern equipment spot-inspection maintenance (ESIM) system for coal mining, and further explains the three-level logical model and construction method of it. The ESIM can achieve the requirements of real-time monitoring, automation control and intelligent analysis, which helps improve scientific management of coal equipment.

The development of telecommunications plays an essential role in the economy, as it affects the opportunities for communication between economic actors at both the national and global levels. Today mobile communication companies, which provide quality communication and information retrieval opportunities through the variety of their services, technological features and tariff plans, are important telecommunication providers. The aim of the present research is to examine the leading mobile communication service providers in Latvia by employing the theoretical findings of communication technology and telecommunications.The research used the following methods: monographic, induction and deduction, graphic, comparison, as well as competitiveness assessment based on the competitiveness index.The research described the theoretical aspects of telecommunications, examined the leading mobile communication service providers in Latvia, their most important financial performance indicators, services and tariff plans offered as well as assessed their competitiveness.Examining the mobile tariff plans and the services included therein, it was found that they were quite similar. However, an examination of each offer in more detail revealed that there were many nuances that were important to the client and that should be paid attention to.After assessing the competitiveness of the leading mobile communication providers, it was concluded that Latvijas Mobilas Telefons scored the highest number of points, Bite Latvija was in second place and Tele 2 took third place. An assessment of the key factors of competitiveness for the providers revealed that the company Latvijas Mobilais Telefons needed to improve the positions where its competitors had higher ratings: its discount system, the prices of services and the supply of services.

Aim; To solve the problem of innovation laboratory instrument management and improve laboratory management level. Method; It is necessary to do an excellent job in managing innovative laboratory equipment by improving the equipment management system, functional division management, appointment registration, and strengthening the construction of management teams to guarantee the cultivation of innovation and entrepreneurship capabilities of undergraduates. Results; The number of innovative experimental projects approved and the number of project groups that the laboratory can accept at the same time was increased significantly. The utilization rate of laboratory equipment has increased, and the vacancy rate has decreased. Conclusion; Excellent instrument management can significantly improve the efficiency of scientific research in the innovation laboratory.

Abstract: In the world of technology that is increasing, then as humans we will not be separated from the process improvement that occurs. From year to year, it is certain that this increase will certainly. Increasingly rapidly occurring in communication technology. Communication technology has also penetrated the military world, especially in MQTT-based communications. In this research, MQTT-based technology is applied to implement real time tracking system on android. This system is used to send the longitude and latitude coordinates of the personnel so that these points can be known directly via android. From this pure experimental research method, the coordinate point data will continue to be monitored and the existence can be known continuously. This system is designed on a VPS server or Virtual Private Server, so that all devices even though none of the networks can communicate with  each  other  as  long  as  they  have  access  rights  for application user.

Abstract The companies engaged in brown coal mining are looking for ways of managing the mining process as efficiently as possible. The principal mining technology used for brown coal mining in our country, but also in Germany and Poland, are wheel excavators. The evolving GNSS technology has enabled designing and realisation of systems for determining the spatial position of the excavator wheel. The visualisation of the wheel's spatial position and tracking of its real-time motion is performed in the Czech Republic by the program Mine Model developed by the company KVASoftware. One of the most important tasks of mine surveyors is the calculation of the volumes of the extracted masses. The described system performs this task in real-time. This article describes an application that is used to automate volume calculations.

For factory automation, devices and machine make a lot of space has become crowded and full of workers makes the operation of the pipeline space is limited, the problem of accidents become more frequent as the frequency will gradually floating surface have to seriously. The combination of embedded systems based on ZigBee technology to enhance the quality of research objectives of industrial safety, in addition to the general control inherent in using the system outside the ZigBee wireless technology to a remote control. Industrial application platform measurements have the thickness of the degree of screening, vibration sensor, weight classification, current sensing, energy monitoring, load switching, temperature monitoring, and carbon dioxide concentration. From the existing literature found in this study combined with embedded ZigBee for industrial real-time measurement system is an innovative technology. In this study, in addition to the discussion platform, the data for statistical measurement and analysis are also discussed in detail, through wired and wireless synchronization of the system measurement and monitoring, will be able to reach a real-time and can improve the safety of plant safety monitoring.

In this paper, the design scheme, technical route and system structure of the interactive marine incinerator operation training system based on Web3D are proposed based on the study of the marine engine room simulator project. The virtual reality technique, visual C# and IE real-time interaction technology are introduced to the marine incinerator operation training system and the development thoughts of the interactive marine incinerator operation training system based on Web3D are elaborated based on the 3D modeling optimization and real-time interaction technology. This study is a new type of marine engineering training mode, it can better meet the STCW convention in Manila amendments on incinerator equipment management requirements.
