calculating the deviation value of the acquisition precision data of each point position by adopting a Grabbs test method or a kurtosis test method;
judging whether the deviation value of the point position acquisition precision data is larger than an observation threshold value, if so, judging that the point position acquisition precision data is abnormal data, and if not, judging that the point position acquisition precision data is standard data.
3. The method for quickly and dynamically updating the GIS data of the drainage facility based on the handheld RTK equipment according to claim 2, wherein the preset precision is 0.05m.
4. The method for quickly and dynamically updating the GIS data of the drainage facility based on the handheld RTK device according to claim 3, wherein the using the portable handheld RTK device calibrated by the test to perform the point location acquisition on the urban drainage network specifically includes:
connecting the mobile terminal equipment with the portable handheld terminal RTK equipment through Bluetooth or a data line, and logging in the integrated operation module on the mobile terminal equipment;
determining the region type of the region to be acquired, and determining an acquisition target point position of the region to be acquired based on the region type of the region to be acquired and the calibration point position data;
and the portable handheld RTK equipment is perpendicular to the position above the acquisition target point, and acquires the elevation and coordinates to obtain a measurement result.
5. The method for quickly and dynamically updating the drainage facility GIS data based on the handheld RTK device according to claim 4, wherein the drainage facility GIS data management platform dynamically updates the urban drainage pipe network data based on the measurement result specifically comprises:
transmitting the measurement result to a facility inspection and data error correction subsystem;
summarizing the data error problems found in the measurement results based on the data error correction function in the facility inspection and data error correction subsystem and the drainage facility GIS display subsystem to obtain error summarized data;
the error summary data is imported into a drainage facility GIS data standardization management subsystem, and the reported data error problem is checked;
if the auditing is passed, carrying out standardized processing and correction on the urban drainage pipe network data, updating and releasing new urban drainage pipe network data service, and feeding the auditing result back to field inspection personnel;
if the auditing is not passed, the auditing result is fed back to the mobile terminal to carry out data verification and submission again.
