Research And Design On Portable Monitoring Device For Petrochemical Production Process

In this paper, hardware and software design and development of the respective one of the petrochemical production process applied to a portable Monitoring and Control device, the monitoring of their production process presents a new solution. Monitor the hardware implementation process, including hardware design and selection, as well as integrated design and implementation of integration. On the composition of the monitor in each component and their functions are achieved by a detailed description of the layout through the rational design of the hardware integrated into the monitoring of the shell, taking into account the external interface, and earthquake-resistant, heat dissipation and so on. Software portion of the concrete implementation steps, including the database, interface and application development. Among them, the database is the core content of the Monitor, the topic selected PI database system as a monitor in the core database, on this basis, develop appropriate to their interface with the monitoring software. Finally, the turn to complete the software part of the integration.The Monitor, when used, the fault diagnosis instrument access through an Ethernet interface, petrochemical production plants DCS system, or via a plug-type multi-channel AD / DA data acquisition device direct access to on-site signal meter cabinet. Monitor small size, light weight, easy to carry, to solve the fault diagnosis technology to actual industrial field application bottlenecks, especially for systems with DCS or PLC or smart meter petrochemical production facilities, with a network cable can plug the advantages of a to use very convenient.After Aspen Dynamic simulation of the production process to test the practical effect of this Monitor, through testing can see that the Monitor can be successfully interact with the host connected to the data, real-time to reflect the production process running at the same time, when the key parameters change, the ability to achieve real-time alarm. Troubleshooting software installed by analyzing the data in the database can display diagnostic results, for technical staff or operators for reference. Monitor can be basically achieved the previous design features.
