【摘要】：由于传统的单片机开关电源节能控制系统设计不完善,可靠性和抗干扰能力均偏低。因此,构建可靠性和抗干扰能力较高的单片机开关电源节能控制系统,该系统由节能控制模块和单片机监控模块组成。节能控制模块由滤波器、脉冲宽度调制电路和变压器组成。滤波器将单片机开关电源中初始直流电的不正常波形除去,再经由脉冲宽度调制电路将其转换成方型波,并输出到变压器中进行单片机开关电源的节能控制,最终使其以低能耗直流电的形式输出到单片机监控模块。单片机监控模块为低能耗直流电提供数据显示功能,并对单片机开关电源进行实时监控。软件给出系统对节能控制模块的控制流程图,以及检测单片机开关电源是否需要进行节能控制的代码。实验结果表明,所设计的系统具有较高的可靠性和抗干扰能力。
[Abstract]:Because of the imperfect design of the traditional energy-saving control system of single-chip microcomputer switching power supply, the reliability and anti-jamming ability are low. Therefore, the energy-saving control system of single-chip microcomputer switching power supply with high reliability and anti-interference ability is constructed. The system is composed of energy-saving control module and single-chip microcomputer monitoring module. Energy-saving control module consists of filter, pulse width modulation circuit and transformer. The filter removes the abnormal waveform of the initial DC in the SCM switching power supply, then converts it into square wave through the pulse width modulation circuit, and outputs it to the transformer for energy-saving control of the single-chip microcomputer switching power supply. Finally, it is output to MCU monitoring module in the form of low energy consumption DC. Single-chip microcomputer monitoring module provides data display function for low energy consumption DC, and real-time monitoring of single-chip microcomputer switching power supply. The software gives the control flow chart of the system to the energy-saving control module and the code to detect whether the switch power supply of the single-chip microcomputer needs to control the energy-saving. The experimental results show that the designed system has high reliability and anti-jamming ability.
