Method of scheduling realization of master and slave machines in Internet-of-things terminals and device

Abstract

The invention discloses a method of scheduling realization of master and slave machines in Internet-of-things terminals and a device. The method includes a step of scheduling description table configuring, a step of scheduling running and a step of internal scheduling mechanism realization. After a scheduling description table is configured, firstly a task control block of a scheduling module is created, then a scheduler thread is started, and a time slot value is set for notifying the scheduling module of starting scheduling running. The step of internal scheduling mechanism realization is realized through two threads of a sub-scheduling thread and a work / pausing thread. The sub-scheduling thread is used for lowest-level sub-scheduling realization. The work / pausing thread is used for realization of upper-level work and pausing. According to the method, a common scheduling module is used, thus a master and slave machine scheduling mechanism can be enabled to be easily and quickly realized to reduce the amount of code modification due to synchronization protocol modification and improve synchronization protocol development speed, and development time of a product from demand purposing to market sales is shortened.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a scheduling device of a master-slave machine in an Internet of Things terminal and an implementation method thereof. Background technique [0002] In the scheduling of IoT terminals, if the relationship between the master and multiple slaves is a star network, when the master synchronously controls the functions of the slaves, the master and the slaves can communicate through wires. In order to improve real-time response, a A time-sharing scheduling mechanism. In order to realize the time-sharing scheduling mechanism, it is necessary to schedule according to the predefined scheduling configuration on the basis of high-precision software timer. [0003] There are many existing master-slave scheduling implementation methods, generally through hardware coding, using the most primitive method, directly driving the synchronization signal in the form of a h...

Problems solved by technology

Such a scheduling method is only designed for the protocol it implements. After changing the design of the protocol superframe, the scheduling needs to be reconfigured, and the code cannot be reused basically. Although it implements the scheduling function, it is not a module.
