Differential data transmission mode scheduling method, equipment, medium and product

Abstract

The invention relates to the technical field of differential data transmission, and discloses a differential data transmission mode scheduling method which comprises the following steps: checking a differential data transmission state between handheld equipment and a CORS base station according to a preset polling mechanism; judging whether the differential data transmission state between the handheld device and the CORS base station is an abnormal state or not, if yes, controlling the handheld device to send a radio station switching command to a GNSS receiver, wherein the radio station switching command is used for commanding the GNSS receiver to start the built-in radio station, and the built-in radio station is connected with the CORS base station to obtain differential data sent by the CORS base station. According to the differential data transmission mode scheduling method, intelligent switching of the differential data transmission modes is achieved, the stability of differential data transmission can be guaranteed in the field measurement process in areas such as mountainous areas with poor network environments, and the field measurement efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field differential data transmission, particularly to a transmission scheduling method, apparatus, medium and product for difference data. Background technique [0002] Operation process is performed in the measured outside the industry, the GNSS receiver will be corrected based on the measurement data received by the differential data, to thereby obtain accurate measurement data. Currently, most of the GNSS receiver to receive the difference data by the handheld device: a handheld device connected via a network to a first base station, and receives the differential data CORS; handheld device then transmits the received difference data to the GNSS receiver. However, when the measured outside the industry for mountain or unmanned geographical environment, prone to poor network signal even disconnected from the network, base station or CORS abnormality occurs, then it will cause differential data transmission int...

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a method for scheduling differential data transmission, which can solve the existing method of transmitting differential data through handheld devices, and has the stability of differential data transmission It is not high, and the limitation of the measurement environment is relatively large, which greatly reduces the efficiency of field measurement.

[0004] The second purpose of the present invention is to provide an electronic device, which can solve the existing method of transmitting differential data through a han
