When a ship meets with an accident, the peripheral device can be disengaged conveniently. The mainframe adopts a metal shell body with a separate seal compartment type, the data memorizer of the peripheral device is sealed in the metal shell body, the whole recorder can not be injured by explosion, combustion and impact, and navigation information data can be ensured to be obtained completely. The peripheral device is made of buoyancy material, can float to water surface, send signals, can not sink in deep water along with the ship and is easy to discover and salvage.
Description
The utility model relates to a kind of voyage data recorder of ship.
Voyage data recorder of ship is important information data in a kind of real-time collection storage vessel navigation, for reveal will the time instrumentation that reproduces.Registering instrument is made of sensor, satellite receiver and main frame, sensor acquisition to aeronautical data and after central processing unit, the signal processing circuit of the satellite-signal that receives of satellite in main frame handle, be stored in the storer in the main frame.Boats and ships can be salvaged this registering instrument after having an accident and sinking, and read the data in the storer, and the various sail informations of a period of time before and after taking place with the acquisition accident help the definite culprit of investigation.The main frame of this registering instrument is fixed on the hull, and in the time of at the bottom of hull sinks to than deep water, difficult salvaging obtains.And marine incident generally all is accompanied by blast, burning, impacts, because main frame does not have effective protective device, inner storer is damaged easily, can not obtain complete information.
The purpose of this utility model is a kind of voyage data recorder of ship that has the peripheral hardware memory storage of design, and when boats and ships have an accident, this peripheral hardware memory storage can be separated with main frame, is convenient to obtain the sail information data.
For this purpose, the utility model adopts following technical scheme: voyage data recorder of ship, comprise power supply and the signals collecting receiver that is connected by transmission cable, main frame, in the external device of data-carrier store is housed.
The signals collecting receiver comprises sensor and preposing signal process circuit thereof, satellite receiver.
Main frame comprises parting seal cabin formula metal shell and is located at host circuit in the housing that host circuit comprises signal processing circuit, central processing circuit, the interior storage circuit that is linked in sequence, and the serial communication interface circuit that is connected with central processing circuit.
External device comprises by the shell that constitutes of fire prevention buoyant material, is located at the metallic cylinder in the shell and is sealed in data-carrier store and signal generator in the cylinder.Data-carrier store is made up of the serial communication interface circuit that is linked in sequence, signal processing circuit and storage circuit, and this serial communication interface circuit is connected with the serial communication interface circuit of host circuit by transmission cable.Signal generator comprises that signal takes place, base shakes, phase modulation, frequency multiplication, emission control, power amplification and high-frequency filter circuit.
Since the main frame of registering instrument with in data-carrier store is housed external device be connected by departing transmission cable, when boats and ships have an accident, external device can conveniently take from.Main frame adopts the data-carrier store of parting seal cabin formula metal shell, external device to be sealed in the metal shell, and the damage that whole registering instrument can not exploded, burn, impacts guarantees the complete sail information data that obtain.And external device is made of buoyant material, can shift to voluntarily on the water surface behind the Offhost, can not sink under water with ship, is easy to find to salvage.
Below in conjunction with drawings and Examples the utility model is described in further detail.
