T/CCPEF 065-2020 Low-orbit satellite forest pest and disease data management specification
Basic Information
Scope
Scope: This standard describes the process of acquiring, transmitting, and receiving data from low-orbit satellites, processing the data on a management platform, and modeling pest and disease monitoring. It also sets forth the basic requirements for data management. This standard applies to the use of low-orbit satellites for remote sensing monitoring of forest pests and diseases, as well as for reference designs of operational systems and application systems. Main technical content: Providing broadcast data services enables low-orbit satellite IoT systems to offer area-based broadcast services. When the system needs to broadcast data, the ground gateway station sends the data to be broadcast to the satellite and registers the location area where the data will be sent. The satellite calculates the time when it will fly over this area based on its flight orbit. When the satellite flies over this area, it sends the corresponding broadcast data to the corresponding terminal. In areas without communication or networks in the field, satellite terminal users who have installed satellite IoT terminals can send text messages to the outside world. "Short messages" are actually equivalent to the "short messages" that people usually use nowadays. Short messages can send information of up to 140 characters. When a handheld terminal sends a short message, the current location information can be sent to the platform or other terminals at the same time, and the platform and terminals can analyze or display the latitude and longitude of the sender. When receiving communication information, audible, visual, or symbolic prompts are given according to the settings, and the communication time, sender's address, and communication message are displayed in real time. The accuracy evaluation model compares the sample plots of forest pests and diseases on the ground with the disaster occurrence degree in the corresponding remote sensing monitoring area, and calculates the accuracy rate of
