Safe-Protection System Development For Offshore Platform Based On VC++

Offshore petroleum development has strategic meaning to our country's economy development. With offshore petroleum exploration technology raising continuously, our country has already built up more than 100 offshore petroleum platforms. Petroleum platform construction needs very huge investment, and production environment is very bad. Offshore Platform is a place with a lot of dangers. Once accident takes place, the loss brought to society will be disastrous. So developing safe-protection monitoring system for offshore platform has realistic meaning to secure offshore platform petroleum production.The hazard gas monitoring system is a subsystem of offshore platform safe-protection monitoring system. The function of offshore platform safe-protection monitoring system was given a brief introduction before introducing the hazard gas monitoring system for offshore platform. The next chapters introduced the gas sensor's type choosing, the gas sensor's installation, hazard gas' alarm value definition, and the communication structure design of the hazard gas monitoring system. Then the function of hazard gas monitoring system for offshore platform was introduced in details. The technology such as the multi-threading, the database operating used in the hazard gas monitoring system design were introduced in the last two chapters in details.Hazard gas monitoring system based on VC++ can show real-time monitoring data in data form or in data curve; the historic data can be checked out from database and can also be shown in data form or in data curve; when accident happens, the alarm data can be saved in database effectively and can be checked out any time. All data's effectively saving and management was realized by using ADO database operation technology to connect and operate SQL server database.
