摘要
根据野外监测仪器的特点,设计了一种电源电路,抗干扰能力强、运行稳定可靠并且功耗低。系统采用普通电池供电,要求能保证一年的正常工作时间,这就需要进行合理的芯片选择和系统电源设计。采取了多电源供电,利用特定的信号来唤醒系统功能单元的电源。此电源设计方案已经应用于地下水数据传输系统中,并保证了系统在野外的长期可靠运行。
Based on the characteristics of the field monitoring equipment, a power supply circuit was designed. It had strong anti-interference capability and better stability and reliability. A battery-powered was used. A year＇s time running was required. Chips and the design of the system power supply were required to choose. The multi-power supply was used. The specific signal was used to wake up the system power. The power was applied in the the groundwater data transmission system. It was used in the field measuring for a long time.
