A screening and correction method for real-time rendezvous data of photoelectric theodolite

Abstract

The invention relates to a method for screening and correcting real-time rendezvous data of a photoelectric theodolite, belonging to the technical field of measurement and control. The method includes: screening the angle measurement data of a photoelectric theodolite received by a real-time rendezvous program of a photoelectric theodolite, and then performing a zero-cross jump on the data Correction and earth curvature correction to obtain angle measurement data that meets the requirements of intersection. Among them, the data screening also includes the process of eliminating time abnormal data. After inspection, the invention can effectively preprocess the data, ensure the normal operation of the photoelectric theodolite data real-time rendezvous program, and meet the needs of the measurement and control system for the photoelectric theodolite data real-time rendezvous.

Description

technical field

[0001] The invention relates to a photoelectric theodolite in the measurement and control technology, in particular to a processing of real-time data of the photoelectric theodolite. Background technique

[0002] The photoelectric theodolite is the main measurement and control equipment today. It is based on the electrification of the optical theodolite to realize the synchronous real-time recording of the image of the measured target, the azimuth angle and the elevation angle at the time of measurement. The photoelectric theodolite is used in the tracking and measurement of stationary and moving targets, and is widely used in aircraft test measurements (such as satellite launches, aircraft tests, etc.). While capturing the target image, it can record accurate angle measurement information in real time, and can obtain the accurate central axis offset of the target through the interpretation and processing of the target image afterwards, so that it can be supe...

[0028] A detailed description and explanation will be given below in conjunction with the accompanying drawings.

[0029] as attached figure 1 As shown, a method for screening and correcting real-time rendezvous data of a photoelectric theodolite shown in the present invention is realized through the following steps.

[0030] Step 1: Read the SID, BID, DID, photoelectric theodolite tracking status code ZT, angle measurement data and target miss amount in the PDXP data packet according to the PDXP protocol format and task interface file, and judge the read data and the preset in the rendezvous program Whether the value or range of values ​​matches, filter out the data packets that meet the requirements, and discard the data packets that do not meet the requirements;

[0031] PDXP is a data transmission protocol stipulated by the national military standard, and the realization process of the present invention is completed based on this protocol. Normally, the PDXP data protoco...
