Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
As shown in fig. 1, the unmanned ship navigation data recorder described in this embodiment includes a sensor interaction unit 1, a data acquisition unit 2, and a data recording unit 3.
The sensor interaction unit 1 realizes data interconnection and intercommunication by adopting an Ethernet, converts RS422, CAN, AD/DA and I/O control signals into PCIE signals and then interconnects with the data acquisition unit 2. The hardware interfaces supported by the sensor interaction unit 1 comprise an Ethernet port, a serial port, a CAN interface, a SerDes interface, an SDI interface, an MT optical fiber interface and a VGA/HDMI/DVI video display interface, and support communication protocols such as CAN J1939, TCP/UDP, NEMA0183 and the like. In this embodiment, the sensor interaction unit 1 is configured to collect data of the unmanned surface vehicle autonomous control chassis, the data exchange device, the environmental data recording unit, and the audio data recording unit, and transmit the collected data to the data collection unit through the ethernet interface. The data collected by the sensor interaction unit 1 comprise command data, decision data, navigation data, state data, load data, environment data, audio data and the like on the unmanned ship.
The data acquisition unit 2 is realized based on a four-core CPU adopting an ARM architecture, and the four-core CPU is connected with the signal acquisition amplifier and the digital-to-analog conversion module and is used for processing, classifying, analyzing and encrypting the data acquired by the sensor interaction unit 1. Once the data acquisition unit 2 judges that the unmanned surface vehicle state is an accident state, the data acquisition unit sends flooding or out-of-control alarm information to the data recording unit, and simultaneously triggers the ejection device 3-2.
The data recording unit 3 is used for storing, backing up, processing and encrypting unmanned ship data and comprises a protective box 3-1, and the protective box 3-1 is installed at the stern of an upper deck of the unmanned ship. The top of the protection box 3-1 is provided with a protection box cover 3-4. An ejection device 3-2 and a black box 3-3 are arranged in the protection box 3-1, and the ejection device 3-2 is arranged at the bottom of the black box 3-3. The black box 3-3 is connected with the data acquisition unit 2 through an electric disconnecting-plugging 3-5.
