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 with figure 2 , The steps include:

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

[0038] 1.1 Regarding historical timing data, each site is taken as an element of the cluster, the basic information characteristics and historical timing data characteristics of each site are selected, and the values ​​(or numerical values) of each feature corresponding to each site are calculated according to the selected characteristics. group). The basic information features include the longitude, latitude, historical water level, historical temperature and other information of the site. The histo...

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 field of waterways and water transportation, and in particular to a hybrid type navigation mark alarm intelligent detection method. Background technique [0002] The navigation mark telemetry and remote control system based on the Internet of Things and big data analysis, comprehensively using wireless digital communication GPRS technology, Beidou and GPS positioning technology, microprocessor technology, embedded system and other modern information processing technologies to realize automatic monitoring of navigation lights. And analysis, automatic monitoring and analysis of high-precision navigation mark displacement positioning, automatic monitoring and analysis of the working condition of navigation mark accessory equipment. [0003] In the remote control navigation system, the remote terminal unit (RTU) can collect the status of the navigation mark in real time and return it to the control center regularly. However, due to f...
