A branch of Peninsula Eastern Shipping, Europe's largest shipping company, began producing the first advanced marine "black box" on March 26, 1992. This black box can provide important clues to the mysterious disappearance of ships on the sea.
This voyage recorder that records sound, radar and other data on a tape day and night is based on black boxes used on airplanes. This sturdy black box uses eight-track tape to continuously record the various sounds of the ship's engine control room and the background sound of its vessel as it sails. Dates, time, compass and radar were recorded simultaneously. The entire system is installed in an extremely sturdy, corrosion-resistant, waterproof tweezers that are half a meter square. The "black box" weighs 90 kilograms and is usually placed in the wheelhouse. In addition, the tape can be packed in a fireproof and waterproof fast floating tweezers on the deck. If the vessel unfortunately sinks into the sea, the seawater pressure will automatically cause the raft to surface. The dice are equipped with electronic pointing targets that help locate.
