Frequency converter based on UCOS control and management

Abstract

The invention discloses a frequency converter based on UCOS control and management, comprising a central processing unit, a signal acquisition unit, a display unit, a keyboard unit, a communication unit, an external signal processing unit, a protection unit, a driving unit and a main power unit. The central processing unit runs a uCOS real-time operating system, and uses a mailbox, a semaphore, and a message queue to coordinate and synchronize tasks. The tasks include a signal acquisition task, a PWM driving task, a panel display task, a keyboard scan task, a communication read-write task, andan external signal processing task, a motor algorithm processing task, a system task. The frequency converter based on UCOS control and management has a reasonable and clear coordination and synchronization relationship between tasks, improves the resource utilization rate of a main chip, improves system response time, and is improved in performance.

Description

Technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter based on UCOS control and management. Background technique [0002] At present, the inverters are all bare-metal programs running a main program. The inverter control program with this architecture has complex structure, low real-time performance, and poor stability. It is also difficult to develop new functions in the later stage, and it is often important to re-development. This leads to repeated development and reduces development efficiency, which not only prolongs the product development cycle but also increases development costs. [0003] uCOS operating system (Micro Control Operation System) is a ROM-based, cuttable, preemptive, real-time multitasking kernel, with a high degree of portability, especially suitable for microprocessors and controllers, can be rigorously tested The real-time operating system for spacecraft has the characteristics o...
