The Cape Cod Canal Ship Traffic Control System is designed to make maximum use of presently available radar, TV, microwave and communications equipment. The system is divided into four functional subsystems described below. Radar provides the means of detecting and observing vessels up to twelve miles from the canal entrances. Radar data is transmitted via microwave link to the Control Center at Buzzard's Bay. A 16 inch PPI Display Unit is provided to display video and control the radar. A second display, slaved to the first, is the source for daylight viewing display mounted in the operator's console. Observation of interior canal activities takes place through low light level closed circuit television. Up to eight camera locations provide simultaneous displays at the operator's console. The video is transmitted over a second parallel microwave link. Cameras can be panned, tilted, and zoomed remotely from the control center. The Control Center operator controls four channels of Maritime VHF radio and two Army Maintenance channels. All channels are constantly monitored. There is an intercom facility to permit communication between the console and the remote radar sites or the radio transmitter site. The Control and Alarm Subsystem permits operator control of traffic lights at the canal entrances. If a traffic lamp fails to light, a standby bulb is illuminated and the operator receives a failure indication. In the event of a microwave link failure, the traffic lights automatically switch to RED and control of the lights reverts to the remote site. Alarms are provided at the console to indicate remote site power failure, intrusion, or fire and microwave link failure.
