For the mechanical parts of helicopter easily damaged and often inducing accident, the key system to ensure flight safety of helicopter and achieve the on-condition maintenance is HUMS. In the paper the key technologies of HUMS are researched including position optimizing of the sensors, flight safety monitoring and diagnosing technology, the method of setting threshold, and it is dissertated in detail...
Motor systems are critical equipment in modern industry. To make the equipment maintenance more efficient, this paper proposes an online and remote machine condition monitoring and fault diagnosis system for motor system based on WIA-PA (Wireless network for Industry Automation — Process Automation). The system continuously monitors the status of the target motor systems using wireless vibration transmitters...
In order to strengthen the security guarantee and improve the scientific management level of important equipments, the intelligent internet of things for equipment maintenance (IITEM) was presented in this paper. IITEM collects the static and dynamic information of electrical and mechanical equipments by all kinds of sensors, and standardizes various types of information, so as to suit the information...
Power machinery and key equipments are regarded as the monitoring objects. Remote fault diagnosis system based Web is proposed using multi monitoring methods in dredger, which gives a comprehensive consideration of monitoring technology about performance parameters, lubricant oil, vibration and instantaneous speed. The modern ship maintenance management mode of ??two modes, three levels and four methods??...
The allocation of maintenance action timing highly affects the useful life length of the maintained equipments, direct costs of maintenance and consequently production costs. A reliable maintenance system is critical for any corporation to keep acceptable level of profit and competition. This paper describes a design of an intelligent maintenance which can help maximising the availability of the system...
This paper deals with the testing of instrumentation loops (ILs) in gas turbines during scheduled maintenance. To both guarantee safe operation and save costs on periodical changing of cables, an innovative measurement device that monitors the status of the IL and indicates whether a replacement is necessary, has been developed. The goal of the research described in this paper is twofold: First, the...
Structural health monitoring is a vital part in the management of bridges, particularly as the structures begin to age. Detecting structural faults through the use of sensors is an emerging field that has seen considerable efforts this past decade. Similarly, the use of sensors in bridge management systems provides valuable data on the condition of bridges and external factors affecting the deterioration...
The rotating machinery for engineering process and materials science has become faster and lightweight recently. The machinery has been required to run for longer periods of time and reliable operations. Because machine breakdowns and consequent down times severely affect the productivity of factories or the safety of products and process success depends on the reliability and the efficiency of related...
In order to take any proper maintenance actions the transformers conditions should be acquired. Since the transformer performance is limited by its main insulation condition, we focus on the thermal monitoring. As the transformer failure statistic rises, the root cause and ways to solve the problem should be found. Based on failure modes and effect analysis overloaded, external disturbances and ambient...
