Abstract

A real-time operating system for sensor data processing includes the application layer, an application frame layer, a runtime system and the system kernel. The application framework layer comprises amessage processing module and a sensor management module, the run-time system includes a run-time system interface, a virtual machine and a support library, the sensor management module assigns a thread to process the sensor data for each type of sensor, and the thread data comes from the bottom of the polling thread, and the Polling thread directly reads the sensor raw data from the kernel and returns to the upper thread for further processing.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a sensor data processing real-time operating system. Background technique [0002] The main purpose of the time-sharing system is to allow multiple computer users to share system resources, and to respond and serve online users in a timely manner. It has only weak real-time functions and is clearly different from real-time operating systems. Specifically, for a time-sharing operating system, the time requirements for software execution are not strict, and errors in time generally do not cause disastrous consequences. For a real-time operating system, the main task is to process events in real time. Although events may arrive at unpredictable times, the software must be able to respond within a strict time limit when an event occurs (system response time). The same should be true under peak loads, where a timeout of the system's response can mean fatal failure. In addi...
