【摘要】：随着互联网的发展,人们的办公自动化的水平越来越高。各行各业出于对供电连续性、提高供电安全性等方面的要求,越来越多的使用双电源自动切换设备来减少供电短路所带来的损失。同时随着世界人口的不断增长和世界经济的高速发展,人类消耗的化石资源越来越多,对环境的损害也越来越大。如何在保证供电连续性的前提下减少传统能源的消耗成为了一个课题。本设计的初衷为保证供电连续性的情况下尽可能的使用太阳能、风能等绿色能源从而减少对传统能源的依赖。传统的双电源切换装置以市电为中心,以发电机或绿能为备用电源。本文以设计一个以绿能为中心,以市电为备用电源的双电源自动切换装置为目标,从而节约资源保护环境。本文采用了STC12C5A60S2为主控单元的系统解决方案和性能指标。使用傅氏差分算法对采样值经行计算,以满足采样误差不超过±0.1V的要求。软件方面,在uvision平台下以绿能使用最大化为根本核心进行编程,最后使用protues软件对系统设计进行验证仿真,并得出验证波形。通过对protues提取出的验证波形进行分析,并将验证结果与本文设计之初的预期结果进行对比,很好的证明了本文提出的设计方法的正确性,可为相应的工程设计提供指导。
[Abstract]:With the development of Internet, the level of office automation is getting higher and higher. Due to the requirements of continuity of power supply and safety of power supply, more and more industries use automatic switching equipment of double power supply to reduce the loss caused by short circuit of power supply. At the same time, with the continuous growth of the world population and the rapid development of the world economy, more and more fossil resources are consumed and the damage to the environment is becoming more and more serious. How to reduce the consumption of traditional energy under the premise of ensuring the continuity of power supply has become a topic. The original intention of this design is to reduce the dependence on traditional energy by using green energy such as solar and wind energy as much as possible to ensure the continuity of power supply. The traditional double-power switching device centers on electricity and takes generator or green energy as backup power. The aim of this paper is to design a double power automatic switching device with green energy as the center and municipal power as the backup power, so as to save resources and protect the environment. This paper adopts STC12C5A60S2 as the main control unit of the system solution and performance indicators. Fourier difference algorithm is used to calculate the sampling value in order to satisfy the sampling error of 卤0.1V. In terms of software, the core is to maximize the use of green energy on uvision platform. Finally, protues software is used to verify and simulate the system design, and the verification waveform is obtained. By analyzing the validation waveform extracted by protues, and comparing the verification results with the expected results at the beginning of this paper, the correctness of the design method proposed in this paper is well proved, and it can provide guidance for the corresponding engineering design.
