Abstract

A system for use in monitoring the statuses of a plurality of similar type objects includes transmitting terminals, logic structure and display structure. When used to monitor the status of a hotel room, information identifying the hotel room, and its status, including whether the room is vacant and not made up, vacant and made up, and occupied, is shown on a display. Information identifying a particular room and describing its status is transmitted from any transmitting terminal to the logic. Selected transmitting terminals, such as the cashier'"'"''"'"'s terminal, are given priority in the transmission of data to the main logic over all other transmitting terminals. Structure is provided for indicating errors in the displayed status of a given room resulting from conflicting data relating to that room being received from the transmitting terminals. The system can detect a false report that the room is vacant, or a false report that the room is occupied. Because a hotel contains numerous types of rooms, structure is provided for displaying simultaneously all the rooms of a given type. Both the room clerk and housekeeper have a separate display. The information on the clerk'"'"''"'"'s display is capable of being corrected or updated not only by new information from the transmitting terminals but also by information placed into the system by the clerk and the cashier. Structure is provided to enable the clerk to change the status of any room to any status that may be desired. The clerk'"'"''"'"'s display also shows running counts of total rooms occupied, total rooms vacant, total number of rooms scheduled to be vacated and total number of rooms reserved for new occupants. To prevent the system from failing to operate when all the data expected from a transmitting terminal fails to be received, structure is provided for automatically restarting the system.
