Data acquired by numerous wireless sensors in a large industrial setting is communicated to the operations center via nodes in defined geographic cells where the signals from the sensors may be depowered to naturally attenuate below the perception of most other receiving nodes in the industrial system. It would be optimal that signals would attenuate sufficiently such that most signals in a cell are not discernible to receiving nodes in adjacent cells, but some sensors near the boundary of a cell will probably have to be set at sufficient power that the nearest adjacent receiving cell would necessarily perceive the signal. Data rejection protocols would exclude data from outside a cell and the advantage of the invention is that it minimizes the volume of errant signals leading to more reliable and robust data for operators.

A method and system for monitoring a rail vehicle are provided. The method includes: a local device acquires current operating data and historical operating data of a rail vehicle from a controller of the rail vehicle, herein the local device, which is connected with the controller, is a portable testing device; the local device obtains fault information according to the current operating data and the historical operating data, herein the fault information includes at least one of a fault code and a fault description; the local device obtains a maintenance plan corresponding to the fault information, herein the maintenance plan is obtained through a remote device or a server side; and the local device maintains the rail vehicle according to the maintenance plan. The disclosure solves a technical problem in the traditional art that a troubleshooting process of a rail vehicle is difficult, and when the rail vehicle has a fault, the fault cannot be solved timely.

A web services-based communication system and technique uses an information server to facilitate the communication of process control data and analysis results between a plurality of web services coupled to a communication network. A graphical user interface coupled to the network enables users to store user profile information and configuration information in a database within the information server. The information server uses the configuration information and the profile information to control the operations of a scheduler and a router within the information server to enable users to selectively view process control information via the graphical user interface and to route process control information to appropriate ones of the web services.

An alert notification device of a dental processing machine includes a receiver, a first extractor, and a notifier. The receiver receives error information from the dental processing machine. The first extractor extracts from the error information received by the receiver, as first extracted error information, error information that occurred in a predetermined first time. The notifier notifies a management device to be used by a maintenance company to perform maintenance of the dental processing machine, of an alert concerning the first extracted error information.

Disclosed is an information processing device including: a first communication unit configured to permit communication with a remote maintenance device that remotely operates machine tools; a second communication unit configured to permit communication with the machine tools; an operation unit including a remote maintenance switch; and a control unit configured to, according to whether the remote maintenance switch is in an ON state or an OFF state, determine whether or not to permit communication for remotely operating the machine tools by the remote maintenance device, and control connection and disconnection between the remote maintenance device and the machine tools. Accordingly, it is possible to perform remote maintenance on machine tools while maintaining the confidentiality of information indicating the operation state of the machine tools.

A resource allocation system for a production facility stores: a production schedule assigning production tasks to machines of the production facility, each production task comprising a production time window during which a machine is occupied with the production task; a maintenance schedule assigning maintenance tasks to service resources, each maintenance task comprising a maintenance time window during which a machine is occupied with the maintenance task; and a maintenance plan comprising maintenance rules for generating maintenance tasks, the maintenance rules at least comprising a scheduling rule from which a time after which a machine has to be maintained is derivable. The resource allocation system is configured for determining maintenance tasks for machines based on the maintenance rules, wherein the time window of a maintenance task for a machine is determined from a previous maintenance task, the scheduling rule for the machine and the production tasks for the machine, such that the time window of the maintenance task does not overlap with the production tasks.
