Abstract
A vehicle tracking system central host comprises a memory cache processor for managing a plurality of memory caches and a storage device linked with the memory cache processor, for receiving messages from the memory caches and writing them to a database. There are n receiver ports each for receiving message packets of an associated protocol from remote vehicle on-board tracker units. There are also n receiver processors, each associated with a port and each receiver processor being for: reading message packets received at the associated port, performing initial processing of the message packets including adding headers to provide processed messages, and writing the processed messages to a log dedicated to the receiver processor. There re also n decoders, each associated with a receiver processor log and being for (a) instantiating a service object for each log, (b) executing each service object to instantiate a message object in which data from a current message is written as attributes of the message object such that instantiation of the message object normalizes the message and the normalized fields include a vehicle identifier field, and (c) executing each service object to repe…
