Problems solved by technology

However, this type of method needs to transmit marked content, which increases the additional burden of data transmission and reduces the transmission efficiency.
Moreover, this method needs to be used synchronously by the sending end and the receiving end. If a device in the system wants to use this method to transmit data, the device interacting with it will also change accordingly.
The UAV system has strict requirements on real-time and transmission efficiency, and there are many devices in the system, so changing the communication method involves more content and is more difficult

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0033] First, define the type and format of the protocol file according to the actual situation of the UAV system, and formulate the protocol file according to the transmission protocol. In this example, the suffix of the text protocol file is defined as .frm. The protocol file specifies the serial number, data type, transmission coefficient, name, unit, normal value range, alarm value range, and effective value range of the UAV data item. The serial number of the data item is an integer type, the value is unique, and the same serial number value cannot appear. The data type is defined as an enumerated type, including BOOL (Boolean), CHAR (single-byte integer), BYTE (single-byte unsigned integer), SHORT (double-byte integer), WORD (double-byte signed integer), LONG (four-byte integer), ULONG (four-byte unsigned integer). The transmission coeff...

Abstract

The invention discloses an unmanned aerial vehicle multi-protocol transmission data analysis method, which can complete dynamic multi-protocol data analysis under the conditions of not changing programs and not increasing extra transmission data. According to the method, a text protocol file is read mainly through control software during running, and an unmanned aerial vehicle transmission protocol is automatically obtained. Control software uses a unified data structure to store transport protocols and real-time data. When an unmanned aerial vehicle system modifies the transmission protocol,only the text protocol file needs to be modified, and control software does not need to be modified. In the research, development and upgrading process of the unmanned aerial vehicle, the method can be used to reduce a large amount of work caused by transmission protocol change and improve the flexibility and maintainability of the unmanned aerial vehicle system under the condition of not changingthe transmission mode of the system and not reducing the transmission efficiency.

Description

technical field [0001] The invention relates to a multi-protocol transmission data analysis method applied to an unmanned aerial vehicle system, belonging to the field of automatic control of unmanned aerial vehicles. Background technique [0002] The protocol of UAV data transmission is usually solidified in the program of the control software. When the transmission protocol is changed, the program must also be changed accordingly. During the development or upgrade of drones, the transmission protocol is often changed. Along with this, the programs that control the software are often changed. Changing the program frequently requires a lot of work, and changing the program frequently adds uncertainty and various risks to the system. [0003] In recent years, there have been many studies based on data exchange formats such as XML or JSON, which can make data transmission independent of programming languages. However, this type of method needs to transmit the marked content...
