摘要:
电源是一切电子设备的心脏,是保障电子设备正常运行的关键,但目前针对地震观测台站使用电源的相关研究较少,本文在分析目前台站电源存在问题的基础上,开发设计了适用于台站的通用智能电源控制器,该控制器以STM32F107微处理器为核心,设计了相应的信号采集、电压控制及驱动电路,整机功耗约0.6W、工作电压范围DC7~23V,其通过外接方式即可对台站原有供电系统进行功能扩展和优化,满足低功耗、易操作、高可靠等设计要求,具有较好的推广价值。

Abstract:
Power is the heart of all electronic equipment as well as the key to ensure the normal operation of electronic equipment. However, there is no enough previous research on the power supply used in seismic stations. Based on the analysis of the existing problems of power supply in seismic stations, a general intelligent power controller is developed and designed in this paper. The control system is with microprocessor as core designed the corresponding signal acquisition, voltage control and drive circuit. The device has about 0.6 watts of power consumption and operating voltage range from 7 to 23 volts, and is capable of expanding and optimizing the original power supply system function of the station through external connection, which meets the design requirements of low power consumption, easy operation, and high reliability.
