Problems solved by technology

This process requires a lot of computing resources, and because the parameters of different types of sensors are different (such as the speed of sensor collection information, the protocol of sensor and processor communication, the speed of sensor and processor communication, etc.), the joint debugging process of multiple sensors is relatively complex. Complicated, increasing the difficulty of development for developers

Embodiment Construction

[0032] The present invention is described in detail below in conjunction with accompanying drawing:

[0033] This application aims at the deficiencies of the existing sensor information collection system, and provides a new type of sensor information collection method, which reduces the computing pressure of the processor in the circuit, and at the same time reduces the development pressure of developers.

[0034] The acquisition circuit of the multi-sensor information acquisition and navigation system of the present application has multiple data input and output interfaces including IIC interface, SPI interface, UART interface and FSMC interface, and can connect different sensors as required. This multi-sensor information acquisition and navigation system will Automatically identify the type of sensor, data and communication mode, and perform corresponding calculations on the data, and finally package and send the acquired raw data and processed data to the host computer throu...

Abstract

The invention discloses a multi-sensor information acquisition navigation system and method.The multi-sensor information acquisition navigation system comprises an information acquisition unit.The information acquisition unit transmits acquired information to a processor unit, and the processor unit packages the information and transmits the information to an upper computer after further processing the information.The processor unit comprises a filter module, a posture calculation module, an inertial navigation module and a control module of a gyrostabilizer.Needed algorithms are built in the processor unit to perform operation processing on the acquired information, the processing speed is high, and meanwhile the operation burden of the upper computer is relieved.

Description

technical field [0001] The invention relates to a multi-sensor information collection and navigation system and method. Background technique [0002] In the research and development process of intelligent water vehicles, it often occurs that data from multiple sensors must be collected and processed at the same time. If all the sensors are connected to the central processing unit, developers need to program all the sensors separately to process the data collected by each sensor. This process requires a lot of computing resources, and because the parameters of different types of sensors are different (such as the speed of sensor collection information, the protocol of sensor and processor communication, the speed of sensor and processor communication, etc.), the joint debugging process of multiple sensors is relatively complex. Complicated, increasing the difficulty of development for developers. Contents of the invention [0003] In order to solve the deficiencies in the...
