Problems solved by technology

However, GPRS data can only be transmitted through the 2G network, and the speed is relatively slow; moreover, due to the different network coverage of different operators, it may happen that the GPRS data of the RTK base station is provided by operator A, but in the actual operation site A operator's The network coverage is not good, which seriously affects the communication efficiency of the RTK base station

Embodiment Construction

[0054] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a data communication method of the present application, which may specifically include the following steps:

[0056] Step 101, detecting the current network status of the RTK base station;

[0057] Usually, before using the plant protection UAV for plant protection work, it is necessary to set up an RTK base station near the work site. RTK (Real-time kinematic, carrier phase differential technology) is a differential method for real-time processing of carrier phase observations of two measurement stations, which can send the carrier phase collected by the reference station to the user receiver, so as to calculate the coo...

Abstract

The invention provides a data communication method, device and system. The method comprises that a present network state of an RTK base station is detected; and when the network state satisfies a preset condition, RTCM data is sent to a mobile terminal, and the mobile terminal forwards the RTCM data to a server. The problem that in the prior art, the RTK base station cannot transmit the RTCM data to the server timely due to poor coverage of 2G network is solved; the mobile terminal forwards the RTCM data sent by the RTK base station; and network connection advantages of the mobile terminal itself can be used fully, the data transmitting speed from the RTK base station to the server is improved, and the accuracy and timeliness of data communication are ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, to a data communication method, a data communication device, and a data communication system. Background technique [0002] Unmanned aircraft, referred to as Unmanned Aerial Vehicle (UAV), is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. UAVs are widely used and are often used in agricultural plant protection, urban management, geology, meteorology, electric power, emergency rescue and disaster relief, video shooting and other industries. [0003] With the development of UAV plant protection technology, and UAV plant protection has the characteristics of small damage to crops and high utilization rate of pesticides, more and more farmers or farmers have begun to use UAVs for plant protection operations, especially the use of plant protection Drones spray pesticides and fertilizers, etc. [0004] I...
