SHIP MOVEMENT CONTROL SYSTEM Russian patent published in 1994 - IPC

FIELD: devices for avoiding collisions of movable objects. SUBSTANCE: system has two separated receiving-transmitting sets 1 connected one to the other through radio channel. Each set has receiving-transmitting aerial 2 antenna relay 3, receiver 4, phone set 5, transmitter 6, two pulse generators 7 and 8, indicator 9, AND gate 10, control unit 11, threshold device 12, square pulse generators 13-15, adder 16, data processing unit 17, counter 18, code-to-code converter 19, groups of flip-flops 20, 21, group of OR gates 22, OR gates 23-25, registers 26, 27, delay member 28. Type of manoeuvre of sea vessel coming from the opposite direction (or passing vessel) is determined in the systems 1-3 minutes later beginning of its tracking. Besides, systems performs basic functions of secondary locator: it may determine location, set and parameters of moving objects which are in the zone of reception. EFFECT: widened functional reliability. 3 dwg
