As shown in FIG. 1, the marine trial run measurement and analysis system according to the present invention includes a DGPS reception device, a DGPS satellite signal, and a measurement signal of various navigation equipment, which receive a satellite signal including ship position and speed information from a DGPS satellite. A navigation interface device that collects and converts analog signals (heading angle, rpm, BHP, wind speed, wind direction, wave height, tidal current, etc.) into digital signals, and converts the digital measurement signals and satellite signals from the navigation interface devices. It consists of a host computer for commissioning that receives and analyzes and calculates the ship's maneuverability test according to user-set conditions

Looking at the detailed configuration of such a sea trial test measurement and analysis system, as shown in Figure 2, the DGPS receiving device 110 receives the satellite signal including the position and speed information of the vessel from the DGPS satellite, and the measurement by various navigation equipment A navigation interface device 120 for converting a signal and the received satellite signal into a digital signal for communication between systems, measurement means 130 for receiving digital measurement signals and satellite signals from the navigation interface device 120; The digital measuring signal and the satellite signal are received from the measuring means 130 and analyzed and computed according to user setting conditions to selectively control maneuverability tests such as speed test, turning test, zigzag test, stopping test and spiral test. Analysis means 140 is performed to output a test result report.

The measurement means 130 includes information transmission determination means 131 which determines whether to transmit or stop the digital measurement information and satellite information to the analysis means 140.

The analyzing means 140 is an antenna position adjusting means 141 for adjusting the position of the antenna for receiving satellite information from the DGPS, and when information having directionality such as a rudder angle, a heading angle, and a wind direction is received with a sign in an opposite direction Directional information correcting means 142 for correcting this, a use speed selecting means 143 for selecting one of a log speed and a DGPS speed as a speed to be used when performing a trial run, and the speed test, turning test and zigzag.

Referring to the process of performing a trial run by the marine trial run measurement and analysis system according to the present invention configured as described above are as follows.

First, when power is supplied to the system, analog measurement signals such as engine RPM, wind speed, wind direction, rudder angle, heading angle, and BHP measured by various navigation equipments are input to the navigation interface device 120 in real time. At 110, the DGPS satellite signal including the position and speed information of the ship received from the DGPS satellite is input to the navigation interface device 120.

The navigation interface device 120 converts various measurement signals and DGPS satellite signals into digital signals for system-to-system communication, and also transmits them to the measurement means 130 in real time.

The measurement means 130 displays the information transmitted from the navigation interface device 120 based on a preset data reception state output form, that is, DGPS speed, latitude, longitude, GPS time, BHP, rudder angle, and the like. When information transmission is determined through the transmission determining unit 131, the digital measurement information and satellite information received are transmitted to the analyzing unit 140 again.

Implementation of such a measuring means 130 can provide a better convenience to the user by making and using a dedicated program.

For example, in the case of developing a dedicated program for Windows, if a user double-clicks the shortcut icon while the dedicated program is installed on the computer and the shortcut icon is registered on the Windows desktop, the program is driven to operate the navigation interface device (120). Display the DGPS speed, latitude, longitude, GPS time, BHP, rudder angle, etc. from the monitor. In addition, when the left button of the mouse is clicked while the mouse point is located at the information transfer button on the screen, the digital measurement information and satellite information are transmitted to the analyzing means 140.

The test shall be either non-reverse propulsion or inertia stop.

As described above, a test of the corresponding item selected through the test item selecting means 144 is performed while various conditions are input, and the moving distance calculating means 146 calculates the distance between the start point and the end point of the DGPS satellite information by a robin method. To calculate the moving distance of the ship, the total moving distance of the ship is selected by either one of the cumulative distance and the linear distance. That is, the cumulative distance of the position moved every second from the starting point is calculated as the total moving distance, or the total moving distance is calculated as the linear distance of two points in the latitude and longitude of the measurement start point and the end point.

The distance (L) calculation formula by the robin method is as follows.

The robin method employed here is less accurate than other distance calculation methods and has a high degree of accuracy with an error of about 20 m in the 500 km distance calculation.
