Problems solved by technology

First of all, the abnormality of some aids to navigation is regional, and the calculation at the RTU end cannot be judged by combining the data of adjacent RTUs
Secondly, the abnormality of some navigation marks is a gradual change process (such as the position deviation of the navigation mark), but the rule-based method is less flexible, and the alarm effect is poor in such scenarios

Embodiment Construction

[0035] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0036] The present invention provides a hybrid intelligent detection method for navigation mark alarm, please refer to figure 1 and figure 2 , whose steps include:

[0037] 1. Discover similar sites based on historical data; it specifically includes the following steps:

[0038] 1.1 For historical timing data, use each site as an element of clustering, select the basic information features and historical timing data features of each site, and calculate the value (or value) of each feature corresponding to each site according to the selected features Group). Wherein the basic information features include longitude, latitude, historical water level, historical temperature and other information of the site. The characteristics of the historical timing data ...

Abstract

The invention provides a hybrid navigation mark alarm intelligent detection method comprising the steps that 1) similar stations are discovered according to historical timing data and historical alarm data so as to obtain similar station division and similar station data; 2) alarm model training is performed according to the similar station division and similar station data, the historical alarm data and the historical timing data of a previous period of time of the alarm moment so as to generate a secondary alarm model; 3) the real-time alarm data and the historical timing data of a previous period of time of the alarm moment are inputted to the secondary alarm model so as to perform alarm result judgment; and 4) the alarm model in the step 2) is corrected according to the alarm result and the artificial feedback alarm result. According to the method, the navigation mark abnormity can be alarmed through combination of the data mining method and the artificial feedback under the premise of fully using the domain knowledge. Besides, the accuracy of alarm judgment can be effectively enhanced by the method.

Description

technical field [0001] The invention relates to the fields of waterway and water transport, in particular to a hybrid intelligent detection method for navigation mark alarm. Background technique [0002] Based on the Internet of Things and big data analysis, the navigation beacon telemetry and remote control system comprehensively uses modern information processing technologies such as wireless digital communication GPRS technology, Beidou and GPS positioning technology, microprocessor technology, and embedded systems to realize automatic monitoring of the working conditions of navigation lights. Automatic monitoring and analysis of high-precision navigation mark displacement positioning, automatic monitoring and analysis of the working conditions of navigation mark auxiliary equipment. [0003] In the buoy telemetry remote control system, the remote terminal unit (RTU) can collect the status of the buoy in real time and return it to the control center at regular intervals. ...
