Problems solved by technology

The disadvantage of this solution is that the hardware cost is high, and the hardware design is solidified, so it is more difficult to change it, which will eventually lead to usage limitations and compatibility, and it is impossible to store, call, and classify data on a unified public platform
[0004] The second solution is limited to the differences in the hardware of different mobile phones, and the mobile phone only has the GPS function and does not have the Beidou function, and GPS is generally only used for navigation, and the positioning accuracy is not high. Even the best mobile phone finally measures and calculates the area. The error is also very large

Embodiment Construction

[0029] The invention discloses a Beidou measurement system based on a mobile phone module. The system includes a Beidou positioning terminal, a smart phone and a cloud server. In order to better understand the technical solution, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] like figure 1 As shown, a mobile phone module-based Beidou measurement system consists of a positioning terminal, a smart phone, and a cloud server.

[0031] The positioning terminal has a USB interface, and is connected to a smart phone through a USB data cable.

[0032] The smart phone embedded client control software can start the positioning terminal, and extract the original observation value of the Beidou satellite received by the positioning terminal through the USB data line, that is, the original code, carrier phase, ephemeris data, Beidou system time, reception The original coordinates of the aircraft antenna, the original motion...

Abstract

A Beidou measurement system based on a mobile phone module is composed of a positioning terminal, a smart phone and a cloud server. Client control software is embedded in the smart phone; through a USB data line, an original observation value of a Beidou satellite received by the positioning terminal is extracted, and power is supplied to the positioning terminal. The smart phone client includes aplurality of usage modes which are an acre value setting module, a vehicle width setting module, a slope setting module, a unit price setting module and a factory setting module. A cloud server system includes an identity authentication module, an original observation value data storage module, an RTK access module and an analysis and calculation module. The cloud server obtains the data receivedby the smart phone control software through a wireless network for analysis and calculation, and feeds back analysis and calculation results to the smart phone client; and the cloud server can obtainan access RTK differential technology through various methods, analyzes and calculates the original observation value to obtain corrected position information, and finally the area is measured accurately.

Description

technical field [0001] The invention relates to the field of tillage measurement by agricultural locomotives, in particular to a Beidou measurement system based on a mobile phone module. Background technique [0002] At present, there are two types of mumeters on the market, one is a single mumeter device, and the other is to use a mobile phone client to measure the area. [0003] The first scheme is a single mu meter, which uses mu meter equipment to collect, analyze, and calculate the original observation values ​​of Beidou satellites, which involves complex calculations, less data storage, and higher requirements for the main chip and EEPROM . To ensure high accuracy of position data, special hardware needs to be designed to correct the data by using RTK carrier phase difference technology. The disadvantage of this solution is that the hardware cost is high, and the hardware design is fixed, so it is more difficult to change it, which will eventually lead to usage limit...
