Computer-aided dispatch

Abstract: A cellular phone type network tracks public safety workers and their vehicles for computer aided dispatching and automatic vehicle and personnel locating. A worker carried repeater unit communicates by radio with nearby cells, sending periodic identifying signals. The network locates the unit position by methods used for 911 caller locating. A vehicle mounted mobile data terminal with input and display is in short range wireless communication with the repeater unit to communicate therethrough with the network. A panic button on the repeater unit initiates rapid emergency signals to the network to both call for help and locate the worker/vehicle.

Abstract: This paper provides a review of the subject of electric power dispatching. In Section I we show where dispatching fits into the hierarchy of power system operating and planning problems. Section II provides an overview of the issues, concerns and practices of dispatching. Sections III-V are devoted to the algorithmic aspects of dispatching. Finally, in Section VI we highlight the conclusions reached in the proceeding sections and identify a number of research needs.

Abstract: A computer aided dispatch system is provided for use in a trunked communication system. The system comprises at least a master file node and a plurality of user nodes. The master file node contains a data record for each subscriber on the trunked communication system. Each data record has a plurality of fields that may assume various values. Each dispatcher "attaches" to a particular value of at least one field in any of the data records. The master file node maintains the records for each subscriber and automatically transmits an updated record to each dispatcher attached to the subgroup in which the subscriber operates. In this way, dispatchers are continuously provided the latest subscriber status even though the responsibility for monitoring the status of a particular subscriber unit may dynamically pass from dispatcher to dispatcher.

Abstract: Systems and methods for dynamically integrating disparate computer-aided dispatch (CAD) systems are disclosed. The systems and methods provide bi-directional interoperability between disparate CAD systems and maintain stateful ongoing interactions between interconnected CAD systems. Information objects in one CAD system are associated and bound to related objects in other CAD systems through a centralized information hub that transforms data items intelligently to facilitate communication and interaction between the CAD systems connected to the hub. The described systems and methods maintain complete and current perspectives of all relevant information for each CAD system connected to the information hub, thereby eliminating the need for point-to-point intelligence maintained by the CAD systems about the other interconnected CAD systems. As information updates are passed from CAD systems to the information hub and back out to other CAD systems, the information hub transforms and evaluates the information updates ensuring that only necessary information updates are forwarded.
