Automated generation of environmental reports - a case study
A variety of documents generated within the scope of environmental reporting are based on similar and partly overlapping information. However, in the majority of cases information collected for a particular environmental document cannot be reused for other objectives and if then only with huge additional work input. Data need to be updated on a regular basis, e.g. according to the report period. Therefore computer aided and automated reporting would make good sense. This paper introduces an approach of partly automated environmental reporting. The focus thereby lies on automated conversion of environmental assessment data to XML (Extensible Markup Language) format and integration into environmental reports, which will be shown with the software tool Umberto.
Standardisation of XML-based DTDs for Corporate Environmental Reporting: Towards an EML
Discussions concerning companies’ environmental aspects gained considerable importance and challenged business in recent years. Comprehensible and authentic as well as customised corporate environmental reporting requires substantial quantities of relevant information. In order to automate corporate environmental reporting, the presented approach focuses on structuring and standardising environmental documents using the eXtensible Markup Language (XML). In a more detailed fashion, the contribution is dealing with the harmonisation of three current XML-based document type definitions (DTDs) proposed for internet-based corporate environmental reporting. From an academics’ point of view, this harmonisation is thought to be a considerable effort: firstly, for contributing to the discussion of standardising corporate environmental reporting taken as a whole, and secondly, for stimulating the processes towards shaping an Environmental Markup Language (EML). From a practitioners’ perspective, such a standardised XML-based DTD contributes to employ Internet technologies and Internet services productively for corporate environmental reporting. Reporting companies and their target groups are enabled to exploit the huge opportunities and media-specific technical benefits efficiently. The paper is structured in four parts: The first part deals with the design process used to develop each DTD. In the second part, the three DTDs are presented in a more detailed fashion. Based on this, the third part refers to the process of harmonisation of the proposed DTDs. The paper ends with a conclusion.
Fault Diagnosis and CAN Bus/Ethernet Redundancy Design of a Monitoring and Control System
The ship monitoring system is used to monitor and control the working status of various equipment on the ship. The navigational safety of the ship is affected directly by the stable working of the monitoring system. In this paper, a ship monitoring system with fault-type judgment function and bus redundancy is designed to improve system reliability and reduce fault checking cost. A redundant Ethernet/CAN bus communication network is constructed in the system, which connects multiple simulation nodes. The simulation node can simulate the faults that may occur during the communication process and feeds back the fault information to the host computer. The host computer will analyze and display the corresponding fault type on the user interface with the feedback information is received. The system reconfigures the network route autonomously when the simulation node has a communication fault. Routing of fault nodes can be switched to redundant routing, and the load balancing of the communication network can be maintained. Through experimental tests, the system can accurately locate faults and achieve fast switching of redundant routes between buses. Hence, the reliability of data transmission is improved.
