condition monitoring

Industrial communication benefits from wireless systems, which is more flexible, easily scalable and low in maintenance compared to wired systems. Hence, wireless systems are of interest to many producing companies in various industries. However, industrial applications vary broadly in their requirements regarding a communication system. Thus, applications are categorized by their typical requirements, and suitable wireless systems are proposed. Based on these considerations, methods for comparing different wireless systems are reviewed and thereby, the decision making process is supported.

Throughout the whole lifecycle, maintenance activities generally have to be fulfilled regarding technical systems. In logistics networks the creation of value at the nodes by means of rapid turnover is important, so that the availability of the production factor “machine” is essential. The increase in efficiency of support processes encompasses among others the maintenance of machines and installations. Within the paper, a procedure model with case study is presented, which illustrates the change-over to a condition-based maintenance strategy in the seaport surrounding.

Today, the maintenance of pump systems is based mainly on either a breakdown strategy or a time-based maintenance strategy. There are several disadvantages of these strategies: the required availability often is not reached, unscheduled downtimes occur and costs increase because of necessary redundant resources. In future, the requirements of a plant for efficient and cost-effective operation can only be reached through predictive maintenance. In this context, the combined use of technologies like RFID (Radio Frequency Identification) and condition monitoring techniques is a possible solution to increase the efficiency of operation and maintenance. This is accompanied by significant technology-driven organizational changes in maintenance as simplification of work procedures, additional personnel qualification requirements and decentralization of maintenance activities, i.e. on-site maintenance of pumps. Thus, the efficiency and effectiveness potentials of maintenance will be realized ...
