【摘要】：自备电源作为一种脱离电网工作的电源系统，可广泛应用于一些特殊条件和环境下的用电设备。自备电源由多个子模块构成，与用电设备一起构成一个复杂而庞大的全系统。为了保证全系统的正常工作，电源系统本身必须能够稳定可靠地运行。由于电源系统组成复杂，为了确保其供电的可靠性，控制系统需要及时了解各个子模块的实时状态和关键参数，同时各个子模块必须能够快速准确地响应控制指令，，以协调全系统的运行，这些都对自备电源控制器系统的自动化程度提出了很高的要求。于是本文提出以高性能的DSP芯片作为主处理器，以硬件资源丰富的FPGA芯片作为协处理器完成对自备电源系统的监测和控制功能。首先，本文介绍了全系统的主要组成和功能，由此提出自备电源控制系统的设计。主要是以DSP+FPGA的双CPU为核心，详细展开外围的通信、监测、保护、控制和人工操作等硬件电路的设计，主要包括SCI、CAN、1553B通信，I/O控制，电压检测，信号传输，显示和按键以及UPS和蓄电池等内容。硬件设计完成后，就是控制功能的实际实现了，即软件设计，主要需要完成三方面的工作，包括：程序设计、通信协议的软件实现以及控制策略、流程和关键参数的确定，这些工作都要经过大量的重复调试，不断修正。最后，对全系统进行了联机调试，根据所得的实验结果表明，自备电源控制系统的设计能够满足系统的控制和监测要求，系统的设计在理论和实际上都是可行的，可推广应用于工程实际当中。
[Abstract]:As a kind of power supply system, self-provided power supply can be widely used in some special conditions and environment. The self-provided power supply is composed of several sub-modules. In order to ensure the normal operation of the whole system, the power system itself must be able to operate stably and reliably. In order to ensure the reliability of its power supply, the control system needs to know the real-time state and key parameters of each sub-module in time. At the same time, each sub-module must be able to respond to the control instructions quickly and accurately. In order to coordinate the operation of the whole system, all of these put forward a very high requirement for the automation of the self-supply controller system. Therefore, the high performance DSP chip is proposed as the main processor in this paper. The FPGA chip, which is rich in hardware resources, is used as coprocessor to monitor and control the self-supply power system. Firstly, this paper introduces the main components and functions of the whole system, and puts forward the design of the self-provided power supply control system. The main core is the DSP FPGA double CPU, and the peripheral communication is carried out in detail. Monitoring, protection, control and manual operation of the hardware circuit design, including SCII-CAN 1553B communication I / O control, voltage detection, signal transmission. Display and buttons as well as UPS and battery content. After the completion of hardware design, it is the actual realization of control function, that is, software design, mainly need to complete three aspects of work, including: program design, communication protocol software implementation and control strategy. Process and key parameters of the determination, these work after a large number of repeated debugging, constantly revised. Finally, the on-line debugging of the whole system is carried out. The experimental results show that the design of the self-provided power supply control system can meet the control and monitoring requirements of the system. The design of the system is feasible both in theory and in practice, and can be popularized and applied in engineering practice.
