Abstract:
In this paper, the service and management system for field geological survey developed by combining domestic remote sensing satellites with Beidou navigation and positioning satellite technology was discussed. Positioning and real-time communication to the personnel in field geological survey can be achieved through the hand-held terminal to guarantee their safety. Management, command and emergency rescue for field geological survey can be accomplished through field survey situation analysis, operation route administration and the spatial information display platform. According to the management characteristics of field geological survey, and based on the grid pattern design, six kinds of nodes were set up including operation management center node, remote sensing data service center node, professional application center node, regional center node, field station node and mobile node. The operation management center node and remote sensing data service center node were unitary, while the others were multi-node design. The construction standards for various types of nodes were established being favor of the promotion and application of the system in future. The system has a good application prospect in improving the efficiency of geological survey, strengthening security of field operators and raising the level of geological information management.

Abstract:
There are three main disadvantages of geological survey in the northeast China as below:firstly, It's very hard to communicate each other when the people worked in dispersed locations; secondly, high fluidity was difficult to manage and arrange; thirdly, it's very dangerous when entering unfamiliar areas. Beidou satellite technology made all these problems solved in a certain extent. It's not only making people communicate each other by text message without mobile phone, but also can take interactive multi-route business strategy. The security warning plan database stored in the Beidou satellite service system can be targeted to the terminal area of security demands by pushing safety instructions and emergency disposal program. Workers through Beidou satellite module can get all the information, bulletin and messages timely they need in the area that communication signals do not cover.

Abstract:
The format of production data from field geological survey is various and changes quickly. Customizing software depending on the different interface of production data is the traditional processing mode, and the level of software reuse is low. Appling plug-in technology to the operation management and security safeguard system for field geological survey can retain the framework of the main program, and achieve the functions of processing, storage and query of production data in field geological survey by different plug-in programs meeting the different needs. That can be used in the subsequent system expansion for convenient, safe loading and unloading to plug-in function modules, so as to adapt to needs of different types of outcome data in field geological survey, and improve system reusability and scalability.
