Influence on the Training Mode of Talents in Fire Engineering Colleges Based on OBE

The reform of the domestic fire control system has brought about strong social demand for innovation in terms of updating the fire control engineering education system. There are many existing problems in terms of the training of engineering talents at local fire engineering colleges, including unclear training objectives, an unreasonable curricular system, an overly standardized teaching method, the neglect of students' personal development, the limited practical capability of engineering teachers, overly standardized evaluation methods, and too great of an emphasis on learning results, etc.; all of which relate to the concept of so-called "outcome-based education" (OBE). We propose the following modifications in terms of the OBE training model employed by local fire engineering colleges: the strengthening professional construction, the definition of training objectives, the alteration of the curriculum system, the adjustment of curriculum content, the reform of teaching methods, increased attention to students' needs, the assembly of a contingent of teachers, the improvement of evaluation systems, and the cultivation of applied fire engineering talents for the society.

Experimental Validation of the Mean Pitch Theory

There are several types of exterior ballistic models used to calculate projectile’s flight trajectories. The most complex 6 degree of freedom rigid body model has many disadvantages to using it to create firing tables or rapid calculations in fire control systems. Some of ballistic phenomena can be simplified by empirical equations without significant loss of accuracy. This approach allowed to create standard NATO ballistic model for spin stabilized projectiles named Modified Point of Mass Model (PM Model). For fin (aerodynamically) stabilized projectiles like mortar projectiles simple Point of Mass Model is commonly used. The PM Model excludes many flight phenomena in calculations. In this paper authors show the mean pitch theory as an approximation of the natural fin stabilised projectile pitch during flight. The theory allows for simple improvement of accuracy of the trajectories calculation. In order to validate the theory data obtained from shooting of supersonic mortar projectiles were used. The comparison of accuracy between simple PM Model and PM Model including mean pitch theory were shown. Results were also compared with the angle of response theory.

Designing a Firing Control System on S-60 57mm Cannon

The firing system on the S-60 57mm cannon uses the foot of the cannon crew, which is very dangerous with the position of the crew on top of the cannon when firing. So, a firing system that can be remotely controlled by a computer is required. The design of the S-60 57mm gun firing control system uses a personal computer (PC) as the firing command input, with data communication using WiFi received by the Atmega8535 microcontroller as a voltage regulator for solenoids. The solenoid has a tensile force to drive the hydraulic system where the actuator functions to drive the firing cylinder. Accelero sensor MMA7361, as a variable controller in firing, provides input data simulating the tilt position of the cannon, the position of the 0g sensor is simulated by the cannon in a balanced position. From the test results, there is a difference in sensor designation data with arc angles i.e., angle X by 2.83 degrees and angle Y by 1.86 degrees. The magnetic field produced by the solenoid 0.53 T can attract a maximum load of 20 kg. By changing the distance ratio of mechanical lever to 39.11 cm and 8.89 cm, the solenoid can drive an 88-kg firing cylinder.

Fire safety standards: major changes in 2021

Методика многокритериальной оценки эффективности принятия решений при тушении пожаров на объектах нефтегазовой промышленности

For successful fighting large fires, it is required to develop new and improve existing decision-making mechanisms with the objective to increase the efficiency of actions of the involved fire-fighting units. When making decisions, the fire extinguishing manager must consider the efficiency of possible solutions. Assessment of the efficiency of each possible option is predictive and depends on the system of criteria used. The decision-making process in such conditions is associated with the use of formalized multi-criteria selection procedures, which, in fact, implement multi-criteria optimization. When choosing a multi-criteria solution, the fire extinguishing manager proceeds from his subjective ideas about the importance of the tasks to be solved at each site. Therefore, it is advisable for each fire protection object to develop its own management decision support system that allows to implement multi-criteria optimization based on the preferences of the fire extinguishing manager. The chosen solution option should ensure that several goals of the fire control system are achieved at once. Methodology is considered related to multi-criteria assessment, which can be used for an objective study of the actions of personnel to extinguish a fire for using them rationally in future. The proposed multi-criteria model for making managerial decisions makes it possible to study a wide class of problems of supporting the control of the fire extinguishing process based on the results of monitoring the actions of fire-fighting units. Practical application of the theoretical results in the form of a management information support system allows reducing the subjectivity and improving the efficiency of the management decision-making process when extinguishing fires.

Simplification Options for More Efficient Using of Angular and Linear Measuring Rules for Fire Control

The Army of the Czech Republic is part of a broad military (security) alliance (such as NATO, EU, UN), and is deployable both on its territory, but also on the territory of the states of the members of the alliance, or anywhere in the world. The article focuses on inference of principles and limits for more efficient using of mile rule in school and combat condition. The Linear and Angular issues (which contains mile rule) in perspective Artillery Fire Control System called PVNPG-14M are the important area of the present defence research of Fire Support Department of University of Defence in Brno. The efficient using of artillery rules is necessary condition for the case without automated command, control, and information systems. Only under conditions of comparable efficiency can tasks of the required quality be fulfilled in the event of a malfunction of the automated system. Decision-making processes carried out by the commanders in the present and in the upcoming future depend on the correct application of the presented rules. The paper defines appropriate Linear and Angular variables for common use by Artillery and Mechanized commanders. The presented results are based on the analysis performed in the classroom and at the same time during live combat exercises.

Rotational Drive-Versus-Quality and Video Compression-Versus-Delay Analysis for Multi-Channel Video Streaming System on Ground Combat Vehicles

The multi-channel video streaming system is an essential device for future ground combat vehicles. For the system, the application of digital interfaces is required instead of the direct analog method to support selectable multiple channels. However, due to the characteristics of the digital interfaces that require en/decoding and signal conversion, the system should support the ability to adapt to quality and delay requirements depending on how video data is utilized. To support addressed issue, this study designs and emulates the multi-channel compressed-video streaming system of ground combat vehicle's fire control system based on commercial standards. Using the system, this study analyzes the quality of video according to the rotational speed of the acquisition device and Glass-to-Glass (G2G) delay between video acquisition and display devices according to video compression rates. Through these experiments and analysis, this paper presents the design direction of the system having scalability on the latest technology while providing high-quality video data streaming flexibly.

A Task-Driven Applicable Theory of Autonomous Load Control

Following manual manipulation to manual remote control, special vehicles are now developing towards task-oriented autonomous load control. Based on the original remote load control system, an autonomous control system architecture composed of “decision-making layer-planning layer-control layer-executive layer” was proposed in this paper, and the “task chain-action chain-instruction chain” autonomous task load control method was devised. This theory transforms the remote fire control system that receives operating instruction and controls units, into a task-driven load system that receives tasks to realize automatic/autonomous control. This provides theoretical support for the autonomous combat of unmanned equipment in the future.

The Problem of Fire Control by Automatic Fire Extinguishing System

According to Article 117 of Russian Federal Law 123 of 2008, there is a class of objects historical buildings, exhibition complexes, energy facilities, etc. For these objects, it is not so necessary to eliminate the fire with automatic fire extinguishing systems, as to contain it until the arrival of fire departments. However, this law does not specify certain requirements for automatic installations, the main working substance of which is water and the solutions. The current situation makes it difficult to design, install and test automatic fire control systems. Given this, as well as the foreign experience and domestic developments in the field of automatic fire extinguishing systems, it is important to conduct a special research work. In this work, it is necessary both to conduct several fire tests in terms of the development of a fire with a limited water supply intensity, and to develop a draft of standard “Water automatic fire containment installations. General technical requirements. Test methods”.

ОБҐРУНТУВАННЯ ПРОПОЗИЦІЙ ЩОДО НЕОБХІДНОСТІ ВВЕДЕННЯ ПРОФІЛАКТИЧНОГО ОБСЛУГОВУВАННЯ АВТОМОБІЛЬНОЇ ТЕХНІКИ

The article substantiates the proposals that affect the need for the introduction of preventive maintenance of automotive equipment. Ensuring the operability of the car during operation is especially important for the road transport used today in the east of Ukraine. The purpose of this article is to avoid the above disadvantages, to ensure the performance of the car during operation, especially for road transport used today in the East of Ukraine, this is possible through preventive maintenance. The failure rate parameter is determined for cars that are divided into service groups depending on their operating time and service life. We will take admissible value of parameter of a stream of failures of the car as a criterion of an estimation of time of its faultless work. The lists of works on increase of reliability of the car are established for those elements of the car which, according to results of statistical research, most often lead to loss of the last working capacity. The implementation of preventive maintenance of automobiles during operation will ensure the maintenance of a given level of reliability by preventing failures by determining the residual life of the failure-free operation of vehicle systems and assigning optimal lists of additional work to increase the efficiency of system elements. An example of this is the fulfillment of the tasks of technical support of troops (forces) during an anti-terrorist operation, involving specialists from state enterprises. Such a positive experience needs to be built up and in parallel to equip cars with special devices that are not available in the repair facilities of repair units. As long as the staffing of repair units with such devices continues, it is necessary to create and send staffed teams from state enterprises to military units to carry out adjustment work not only on fire control systems, stabilizers, but also on diesel engine fuel equipment and more, especially Soviet-made equipment. The implementation of preventive maintenance of the car will allow: – reduce vehicle downtime to eliminate failures by preventing them; – reduce the number of current repairs; – reduce operating costsю. Keywords: tuning up (maintenance and repair) of motor vehicles, vehicles operability, reliability, preventive maintenance.

A Vision on Intelligent Medical Service for Emergency on 5G and 6G Communication Era

Emergency service is the most important research field for welfare of human kind. Some examples are ambulances and fire control truck. However, these conventional emergency services are not equipped with appropriate equipment to provide high QoS. For instance, conventional medical emergency services include ambulances with drivers and oxygen supplies only. Another example is the conventional fire control systems that only include fire control truck, which is not suitable for current scenario due to various challenges, for instance, road traffic. In addition, accidental services are unsatisfactory in current and future emergency services. Emergency service is required by anyone at anytime and anywhere. Therefore, it is the time to redefine and restructure the conventional emergency service for saving more lives. Due to the advent of wireless communication technology, it is possible to provide the emergency service on the spot in nearly real-time to save lives. Moreover, integration of Artificial Intelligence with smart devices can change the definition of emergency services. In this chapter, we envision the various emergency services to advance the healthcare services. Besides, we envision the impact of emergency services on healthcare with the help of Artificial Intelligence, 5G and 6G communication technology.
