A REMOTE CONTROL AND MONITORING SYSTEM, FOR AIR TRAFFIC CONTROL APPLICATIONS. CAN BE USED IN BOTH AIRPORT AND WIDE AREA APPLICATIONS. THE MULTI-ACCESS SYSTEM CONSISTS OF A NUMBER OF STANDARD SOFTWARE AND HARDWARE MODULES THAT INTERCONNECT TO FORM A COMPLETE REMOTE CONTROL AND MONITORING SYSTEM. ROUTINE INSPECTIONS AND CHECKS FOR AN ENTIRE AIR TRAFFIC CONTROL NETWORK CAN BE CARRIED OUT BY COMPUTER TERMINALS REMOTE FROM THE RADIO SITES. CAN ALSO PROVIDE CONSTANT WATCH ON BUILDING SYSTEMS SUCH AS INTRUDER AND FIRE MONITOR EQUIPMENT USING OPERATIONAL AND MAINTENANCE DATA FROM CONNECTED EQUIPMENT TO PRESENT INFORMATION IN A CLEAR GRAPHICAL FORMAT TO ENGINEERS AT A REMOTE MAINTENANCE POSITION. THE EQUIPMENT PROVIDES THE HUMAN-MACHINE INTERFACE TO THE SYSTEM AND CONSISTS OF A COMPUTER INSTALLED WITH SOFTWARE WHICH COMMUNICATES DIRECTLY WITH THE REMOTE SITES. MULTIPLE UNITS CAN BE INTERCONNECTED TO PROVIDE REDUNDANCY OR FALLBACK COVERAGE WHEN A MAINTENANCE CENTRE IS CLOSED. REMOTE SITE EQUIPMENT COMPRISES DATA ROUTERS, WHICH COLLATE AND DISTRIBUTE CONTROL AND MONITORING INFORMATION FROM MULTIPLE AIR TRAFFIC CONTROL RADIOS AND ARE LOCATED AT EACH RADIO SITE WITHIN THE NETWORK. INFORMATION IS RELAYED BACK TO THE MAINTENANCE CONTROL CENTRE VIA A LOW BANDWIDTH DATA LINK.

EACH MACHINE IN THE PRODUCTION LINE COMMUNICATES WITH THE LINE CONTROLLER, TO MANAGE OPERATION OF THE LINE. IT INCLUDES A COMPUTER TO COMMUNICATE TO THE INDIVIDUAL MACHINES IN THE PRODUCTION LINE. THE LINE CONTROLLER DETECTS EACH MACHINE IN THE PACKAGINE LINE, THUS RECOGNISING ITS IDENTITY AND PRODUCTION INFORMATION. THE USER THEN CONFIGURES THE LINE LAYOUT GRAPHICALLY AND ENTERS THE PRODUCTION PARAMETERS.

A NUMERICAL CONTROL PANEL WITH A BUILT IN AUTOMATIC DATA PROCESSOR FOR AN ELECTRIC WELDING MACHINE. IT IS THE USERS INTERFACE WITH THE MACHINE. IT DISPLAYS ALL THE INFORMATION GIVEN TO THE USER AND/OR REQUIRED BY THE USER. IT STORES ALL THE WELD CALCULATIONS FOR EACH PIPE. IT TAKES THE ELECTRICAL BINARY SIGNALS FROM THE COMPUTER UNIT AND DISPLAYS THEM IN A READABLE AND USABLE FORM TO THE USER. IT PROVIDES THE USER WITH A VARIED CONTROL OF THE MACHINE VIA SWITCHES AND POTENTIOMETERS THAT VARIES THE DEGREES OF USE. IT CAN TRANSLATE THE MANUALLY ENTERED PIPE SIZE AND DO THE CALCULATIONS FOR PRESSURES AND TIMINGS REQUIRED FOR EACH PROCESS, THEN AUTOMATICALLY CARRIES THEM OUT WITH VARIED INPUT BY THE USER. IT CARRIES OUT ALL THE INFORMATION THEN SENDS IT TO THE COMPUTER IN BINERY CODE.
