英文摘要The invention relates to a power supply circuit which can be used to provide working electric energy for a WIA wireless adapter through a HART bus. The power supply circuit of the invention comprises a voltage drop control module, a system power supply module, a charging control module, an energy storage element, an energy storage monitoring module, a microprocessor, and a WIA power supply module. The voltage drop control module is used to provide a stable voltage for the system power supply module. The system power supply module is used to supply power to the microprocessor and charge the energy storage element. The charging control module is used to realize the charging function of the energy storage element. The energy storage element is used to store the electric energy. The energy storage monitoring module is used to transfer the voltage value of the energy storage element to the microprocessor on a real-time basis. The microprocessor is used to control the charging control module to charge the energy storage element, and control the WIA power supply module to supply power to a WIA wireless communication module. The WIA power supply module is used to provide the electric energy for the WIA wireless communication module. According to the invention, according to the HART bus physical layer protocol, appropriate electric energy is derived from the 4-20mA current loop bus on which an HART instrument is located for supplying power to the WIA wireless communication module.
