Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1, the method for scheduling transmission modes of differential data in the present application is applied to a process of transmitting differential data among a handheld device, a CORS base station, and a GNSS receiver, and specifically includes the following steps:

and setting parameters, namely setting a handbook network parameter on the handheld device before the operation of field measurement is started, wherein the handbook network parameter is used for network connection between the handheld device and a CORS base station, and radio station parameters are built in the GNSS receiver. At the beginning of operation, the default handheld device is in network connection with the CORS base station through the handbook network parameters, the handheld device is connected with the GNSS receiver through the Bluetooth, the handheld device acquires differential data sent by the CORS base station, and the handheld device transmits the differential data to the GNSS receiver through the Bluetooth. The Bluetooth is a Bluetooth module arranged in the handheld device and the GNSS receiver, and the handheld device is a terminal device which is handheld and can be a mobile phone terminal.

And checking the transmission state, namely checking the differential data transmission state between the handheld equipment and the CORS base station according to a preset polling mechanism. In this embodiment, the default initial differential data transmission mode is that the handheld device acquires differential data sent by the CORS base station, and the handheld device transmits the differential data to the GNSS receiver through bluetooth, so that the step is to poll the differential data transmission state between the handheld device and the CORS base station according to units of each second, specifically, check whether the network connection between the polling handheld device and the CORS base station is normal, thereby obtaining a network connection state, and poll whether the CORS base station outputs the differential data, thereby obtaining a differential data output state.

Judging the transmission state, namely judging whether the differential data transmission state between the handheld device and the CORS base station is an abnormal state, when the network connection state is that the network is not normally connected or the differential data output state is that the CORS base station does not output differential data, judging that the differential data transmission state is the abnormal state, at the moment, further performing a first differential delay step, receiving feedback information which is sent by a GNSS receiver autonomously and contains a first differential delay, judging whether the first differential delay in the feedback information reaches a first preset differential delay threshold value, if so, performing an intelligent scheduling step, and if the first differential delay does not reach the first preset differential delay threshold value, returning to continuously performing the transmission state checking step, wherein the numerical range of the first preset differential delay threshold value for judging the first differential delay in the embodiment is 5-30 seconds, preferably 10 seconds, that is, when the GNSS receiver receives the differential data, if the differential data is not received, a first differential delay may be generated, where the first differential delay is a time when the GNSS receiver does not receive the differential data during the transmission process of the handheld device acquiring the differential data sent by the CORS base station. The specific value of the first preset differential delay threshold value can be set by a measurer in the application process. When the first differential delay does not reach the first preset differential delay threshold value, the first differential delay sent by the GNSS receiver is continuously judged at the moment, because the handheld device cannot transmit differential data with the CORS base station temporarily at the moment, and the intelligent scheduling operation is not performed temporarily at the moment. And when the differential data transmission state is not an abnormal state, namely the differential data transmission can be normally carried out, returning to execute the transmission state check.

The step realizes that the differential data transmission mode is switched from the network connection transmission of the handheld device and the CORS base station to the direct differential data transmission of the GNSS receiver through the built-in radio station and the GNSS receiver.

In this embodiment, after the intelligent scheduling, the method further includes:

judging the radio station state, namely judging whether the radio station connection state between the GNSS receiver and the CORS base station is normal or not, if so, not needing processing, and if not, executing a second differential delay judgment step;

and judging the second differential delay, receiving feedback information containing the second differential delay sent by the GNSS receiver autonomously, and when the second differential delay in the feedback information reaches a second preset differential delay threshold, in this embodiment, the numerical range of the second preset differential delay threshold is 5 to 30 seconds, preferably 10 seconds. If yes, executing a network switching step, and if not, not needing processing; the second differential delay in this embodiment is a time when the GNSS receiver does not receive the differential data in the process of transmitting the differential data with the CORS base station via the radio station, and records a duration time when the differential data is not received, and records the duration time as the second differential delay.

And switching networks, namely when the hand book in the handheld device has a network, indicating that the network between the handheld device and the CORS base station can be recovered to be normal, and controlling the handheld device to be in network connection with the CORS base station at the moment, and controlling the GNSS receiver to close the built-in radio station. At this time, the mode of differential data transmission is switched from station transmission between the GNSS receiver and the CORS base station to network transmission between the original handheld device and the CORS base station.

The present invention also provides an electronic device comprising: a processor;

a memory; and a program, wherein the program is stored in the memory and configured to be executed by the processor, the program comprising instructions for performing a method of transmission scheduling of differential data as described herein.

The present invention also provides a computer readable storage medium having a computer program stored thereon, the computer program being for execution by a processor of a method of scheduling transmission of differential data as described herein.

The invention also provides a computer program product comprising a computer program which, when executed by a processor, implements a method of scheduling transmission of differential data as described herein.
