Abstract


Navigable channel depth is to determine the ability of the key factors, accurate and timely information release channel depth can make a reasonable stowage cargo ship, the ship sailed to improve the safety and economic benefits. In order to better grasp the channel depth information, the introduction of channel depth real-time monitoring system concept. Channel depth real-time monitoring system consists of multiple control points, a monitoring center. Each control point is equipped with a depth sounder and ship Automatic Identification System (Automatic Identification System, abbreviated AIS). Depth sounder as a measurement sensor, monitoring points depth information regularly collected, processed and sent to AIS, sent to the monitoring center via AIS. Monitoring center by the shipborne AIS, PC machines and related electronic chart software. Monitoring point from the measured depth to the monitoring center of the visual display, the entire monitoring process is done automatically, to achieve real-time, to effectively perform real-time monitoring system channel depth functional purpose. To complete the monitoring points in the depth sounder data collection work, the water depth data are encoded and transmitted out after sending AIS. Authors using VB for applications with serial communication function MScomm control, using depth sounder asynchronous serial transmission, the sounder output data sent through the post processor AIS. Monitoring points to complete the work on data collection and encoded by the AIS emitted after the monitoring center through various monitoring points AIS receiver depth and location information. For AIS received information that needs to go through an application control center after decoding, to extract the depth and location of the monitoring point parameters. AIS monitoring center through various monitoring points decoded depth and location data, the need to develop application software so that it ECDIS electronic chart visually displayed. ECDIS development software has many, we use MapInfo MapX is the company to provide users with powerful analysis capabilities map ActiveX controls products. MapX provides a variety of tools, properties, and methods to achieve the monitoring point depth display is very easy. Real-time monitoring system is the channel depth sounder measured the depth of information and communication functions of AIS work together to achieve real-time monitoring channel depth of a system, using the system can be measured in real time the various monitoring points bathymetric data, as will these changes The data is saved, you can also be used to analyze the changes in channel depth, which is a pioneering AIS applications. The composition of the system, working principle and its implementation method through theoretical analysis and experimental verification is feasible.
