Design And Development Of Remote Monitoring System For Marine Gas Electric Hybrid Power

With the development of marine hybrid power technology,the data requirements for the design,development and performance optimization of new hybrid power systems are getting higher and higher.The traditional form of on-board monitoring cannot transmit and process data in a timely and effective manner,and the data of ships underway and test benches cannot be effectively utilized,forming "data islands" one by one.Therefore,it is of great practical significance to realize remote monitoring,connect "isolated islands" and give full play to the value of data.Taking the ship’s gas-electric hybrid power system as the monitoring object,carry out the design and development of the remote monitoring system.The main tasks are as follows:First,analyze the structure of the ship’s gas-electric hybrid power system and the remote monitoring data scene,combine the two organically,and determine the overall requirements of the remote monitoring system.Combined with the interactive use cases between users and the remote monitoring system,the functional requirements analysis is carried out,and the remote monitoring system is divided into five functional modules: user management,equipment management,data access,real-time data processing and operation data visualization.Secondly,combined with the concept of remote monitoring of the Internet of Things,the structure of the remote monitoring system of the ship’s gas-electric hybrid is designed.The data access adopts the HTTP protocol,and the access data semantics and access process are designed.According to the large amount of data,continuous occurrence,multi-source and heterogeneous flow data characteristics of the hybrid power system,the technology selection is carried out,and the hybrid power operation data processing flow is designed.Using components such as Kafka and Flink to complete the process development,it solves the problem of mismatch between the rate of consumers and producers in the process of data processing and the multiplexing of multiple intermediate parameters of hybrid indicators,and also ensures the accuracy of data processing without loss,and excavates hybrid power Valuable information.According to the design specifications of the Web backend,the design of the database table,interface and task execution process of each module is completed in turn.Finally,develop the remote monitoring system.Complete the deployment of the operating environment,and conduct functional and performance tests.In the function test,each function module completes the test operation.In the performance test,the average response time under the designed 100 concurrency is no more than 90 ms.In the load test with 1000 concurrency,the average response time does not exceed 1200 ms.In the data processing test,the simulated data access and real-time data processing module did not generate data backlog,indicating that the data can be processed in time.The test results show that the remote monitoring system meets the design requirements.With the increase of hybrid power systems added to monitoring,a scale effect has been formed,and the operation data in the remote monitoring system will exert great potential to promote the development of marine gas-electric hybrid power in terms of design and development,actual operation and daily maintenance.
