A method for measuring and controlling the state of a vehicle

Abstract

The invention relates to an automobile state measurement and control method, and belongs to the field of unmanned vehicles. The invention discloses an automobile state measurement and control method.The state measurement system comprises a platinum resistance temperature sensor module, a resistance-current conversion module, a signal conditioning circuit, an analog switch, an analog-digital conversion module, a storage module, an FPGA controller, a single chip microcomputer, an online calibration module, a power module, and an interface circuit; the platinum resistance temperature sensor is connected to the resistance-current conversion module; and the resistance-current conversion module is connected to the signal conditioning circuit. The invention is directed to the research of the special unmanned vehicle measurement and control technology, and the network RTK has great technical advantages in high-precision positioning; and the application of the network RTK technology in the special unmanned vehicle measurement and control can greatly improve the operation precision, so that it is possible to use the unmanned vehicle in any scene, and the environmental adaptability of special unmanned automobiles can be greatly improved.

Description

technical field [0001] The invention patent relates to a vehicle state measurement and control method, which belongs to the field of unmanned vehicles. Background technique [0002] In terms of civilian use, unmanned driving technology can improve the safety of vehicles. By installing processors and various sensor devices, unmanned vehicles can realize the perception of the road environment, report various dangerous situations to the driver, and give early warnings. Prompt, or in the case of imminent danger, it can intelligently and quickly take corresponding safety measures. [0003] On the basis of investigating the global battle of GPS positioning accuracy, methods and application research, a method of synchronous observation with multiple GPS receivers is proposed, and some of the instruments are fixed as reference stations, and the rest of the instruments can be used as mobile stations for observation, and then The orbits of the satellites will be corrected using the b...

AI Technical Summary

Problems solved by technology

[0004] There are still deficiencies and defects in the construction of continuous operation reference stations in my country, which can be summarized as follows: because the competent department of surveying and mapping has not issued a standard for the construction and service of continuous operation reference stations, there are technical obstacles that data, services and other resources cannot be shared; the CORS system The construction is independent, resulting in network coverage and service gaps in the CORS system; the CORS system actually built lacks unified management, so there are uneven distribution of reference stations in each system, and there are ultra-short and long sides. Accuracy suffers severely
