Inland river intelligent navigation mark position monitoring method

Abstract

The invention provides an inland river intelligent navigation mark position monitoring method. The method comprises steps that the data transmitted by a navigation mark terminal is received, and the data comprises longitude / latitude values of the dynamic position of the navigation mark terminal; gauss-kruger projection forward calculation is employed to solve the dynamic position of the navigation mark terminal and a gauss plane coordinate corresponding to the base point position; a distance between the dynamic position and the base point position is calculated according to the gauss plane coordinate; the distance is compared with an offset distance threshold, if the distance is greater than the offset distance threshold, drift alarm is carried out, if the distance is not greater than the offset distance threshold, the position of the navigation mark terminal is determined to be normal. Through the method, a problem of imprecise calculation of the navigation mark terminal is solved, accuracy and timeliness of drift alarm are improved, error alarm and missed alarm can be avoided, and guarantee is provided for ship navigation safety.

Description

technical field [0001] The embodiments of the present invention relate to the field of navigation mark monitoring, and in particular to a method for monitoring the position of an inland river intelligent navigation mark. Background technique [0002] The malfunction of the navigation mark refers to the loss of the navigation aid function of the navigation mark that should have been functioning, including buoy drift, sinking, light extinguishing, sign collapse and other serious damage. When the buoy management and maintenance personnel find that the buoy is abnormal, they should restore it in time, otherwise it will cause a great threat to the safety of the ship's navigation. Buoy drift is the most serious situation in the abnormal situation of buoys, which will bring great harm to the safety of ship navigation. In my country's inland rivers, ship collision and flood impact are the main reasons for buoy drift. After the navigation mark drifts, it is easy to cause the ship t...

Problems solved by technology

[0004] Due to the weak computing power of the microprocessor of the navigation mark intelligent terminal itself, this alarm mode does not use projection transformation when calculating the distance, but uses various approximate algorithms, so the error is large, resulting in false alarms or no alarms. Occurs frequently, not only brings errors and confusion to management, but also poses a threat to navigation safety
