Real-time task scheduling control method, system and device and readable storage medium

The invention discloses a real-time task scheduling control method, system and device and a readable storage medium, and the method comprises the steps that a real-time task scheduling system receivesa task request, and the task request carries a key value; judging whether a current limiting threshold value needs to be configured or not according to the key value; if so, judging whether a key value is initialized or not; if the key value is not initialized, submitting the task request to the real-time task execution controller after the key value is initialized; if the key value is initialized, obtaining a current current limiting number of the key value; after adding one to the current limiting number, judging whether a current limiting threshold value is reached or not, if so, subtracting one from the current limiting number, and submitting the task request to a real-time task waiting queue; and if not, submitting the task request to the real-time task execution controller. Data flow limiting is achieved th
