基于ARM的双电源信号采集及切换控制技术
[Abstract]:With the development of social economy and the improvement of people's life, the continuity of power supply is becoming more and more important. In order to ensure the continuity of power supply, many important occasions are equipped with two power sources. The automatic switching switch of dual power supply can effectively and accurately realize the switching between the two power sources. The continuous development of modern science and technology has promoted the progress of the overall level of low-voltage electrical appliances to a great extent. The automatic switch of double power supply occupies a very important position in the field of low-voltage electrical appliances, so its importance continues to improve. Performance is also constantly improving, widely used in a variety of important load occasions. Based on the careful study of the working principle of double power automatic switching switch, the hardware circuit is designed and the software program is written in this paper. Based on the embedded Linux system, the driver and application program of the device are written to collect the voltage and frequency signals of the power supply, and the collected results are displayed on the LCD screen. If there is a failure, the microprocessor control switching control device realizes the switching between the common power supply and the standby power supply. In addition, the hardware and software anti-interference measures of dual power automatic switching switch are also studied. The dual power supply signal acquisition system designed in this paper can detect the voltage and frequency signals of the two power sources in real time and accurately, and display the results on the LCD screen. At the same time, the advanced ARM chip and embedded Linux system are applied in this design, which increases the reliability, intelligence and efficiency of the double power automatic switch, improves the overall value of the device, and can be applied to the industrial field.
