1. A national forest resources continuous inventory cloud platform, comprising:
a perception layer device, comprising a tree diameter measuring sensor, an environmental sensor, a tilt sensor and a data collection terminal comprising a processor and a memory, configured to collect and obtain types and radial growth of sample trees and temperature and humidity environmental factors of an inventory sample plot, store and transmit collected information to a network layer device;
the network layer device, comprising a communication relay apparatus, a communication base station, a communication receiving apparatus, and a device for completing optical fiber communication and Internet transmission, configured to gather data collected by the perception layer device, and transmit the data to a platform layer device;
the platform layer device, comprising a computing server including a processor for building a computing resource pool, a storage server for building a storage resource pool, and a network server and a gateway for building a network resource pool, configured to provide computing, storage and network resources for the national forest resources continuous inventory cloud platform
wherein the data collection terminal is configured to obtain server side information, connect to the communication relay apparatus and the tree diameter measuring sensor on survey site for restoration of sample trees on the inventory sample plot and collection, input and computing of data, configure and manage the communication relay apparatus and the tree diameter measuring sensor on site, receive device maintenance information by patrol personnel, survey changes of the inventory sample plot, and update devices;
wherein the platform layer device is configured to
summarize and count inventory sample plot data that are surveyed and collected by the data collection terminal and automatically collected by monitoring devices, check a logical relationship between survey cards, analyze overall sampling accuracy, count achievement reports, and provide survey form templates that the data collection terminal need to download and related data table configuration functions;
supervise statuses of communication relay apparatuses and tree diameter measuring sensors arranged in all inventory sample plots, establish a grid management system for investigators and forest rangers, carry out patrol tasks for inventory sample plots, and confirm device maintenance and update results;
carry out forest resources monitoring, ecosystem evaluation and important index assessment, and provide visual data display and sharing services based on basic data and evaluation results; and
wherein the data collection terminal is configured to
provide a user with interactive modes based on map operations, and provide basic map operation functions of translation, zoom-in, zoom-out, and hierarchical display, and advanced map operation functions comprising positioning, navigation, track collection, and photographing;
download survey forms comprising sample plot cards of previous national forest resources continuous inventory, an inventory sample plot database, and field survey record forms, as well as basic data and tables comprising satellite remote sensing images, inventory technical rules, dominant tree species maps, and unitary volume tables;
input basic information of the inventory sample plot, sample plot positioning and arrangement, survey records of sample plot factors, measured maps of fixed sample trees, tree height measurement records, forest disaster survey records, vegetation survey records, underwood survey records, natural regeneration survey records, sample plot change survey records during a review period, unformed afforestation land survey records, bamboo scale record charts, miscellaneous bamboo sample survey record charts, economic tree species survey record charts, and track photo recorded information;
measure types of mobile signals on site, select communication relay, test strengths of mobile signals or Beidou signals, and test a success rate of data transmission by communicating with a communication receiving end;
connect to the communication relay apparatus, set a data collection frequency, determine start time and start duration of the communication relay apparatus and the tree diameter measuring sensor, and estimate a theoretical monitoring time length according to a data collection frequency set by the user and battery capacity;
connect to the tree diameter measuring sensor, and after confirming the correct connection, input information of a surveyed sample tree, including a sample tree number, a standing tree type, a tally type, a tree species name, a tree species code, an early diameter at breast height, a forest layer, a cross-angle land type serial number, an azimuth angle, and a horizontal distance;
trigger background communication events of the tree diameter measuring sensor and the communication relay apparatus after the information of the surveyed sample tree is input, wherein the tree diameter measuring sensor transmits the device number and the survey input sample tree information to the communication relay apparatus for storage;
survey of all sample trees is completed, connect to the communication relay apparatus, obtain all tree diameter sensor data stored in the communication relay apparatus to the data collection terminal, compare the tree diameter sensor data with previous survey and surveillance data, check whether there are missing data, check abnormal change data, and check whether the tree diameter measuring sensor currently installed has low battery capacity;
when receiving an inventory sample plot patrol task issued by a provincial or national user, view patrol task information comprising the number of a patrolled inventory sample plot and main patrol content, submit patrol task personnel and a time schedule after acknowledgment, and receive provincial or national task completion acknowledgment information after patrol; and
fill in patrol task completion after the inventory sample plot is patrolled on site, fill in update information factors for a device to be updated, or retest the inventory sample plot and arrange monitoring devices, and provide on-site patrol results and photos.
