Cloud service Cloud service is a series of cloud services specially designed for measuring users. It mainly focuses on mobile internet and data management applications. Based on the measured location data, it can realize the integration of internal and external measurements through the Internet experience. It can build independent management for users. Private cloud service.
Five major service modules 1. Equipment management Provides equipment management modules, allowing users to know the existing equipment configuration, attendance status and health status. At the same time, it provides advanced functions such as remote upgrade of equipment, remote registration and remote equipment;
2.Equipment monitoring Real-time monitoring of the equipment operation status, through the electronic base map to intuitively understand the equipment location information, user information, and measurement range, so that equipment can be traced, queryable, and coordinated;
3. Data management provides a cloud storage service, including user trajectory information, control point information, parameter information, trajectory monitoring during the measurement period, data fusion and interface conversion, task completion statistics and other functions;
4. Collaborative work Under the same project, the measurement data of all working members can be shared in real time, and the data of other project members can be intuitively viewed on the handbook, so that the measurement process can achieve no missed test, no retest, and help test
5. User management takes people as the object, establishes the project organization structure, sets the object permissions according to the structure, and realizes "what can be done" and "what is being done" management.
