摘要： The present application discloses a HART circuit and a method for determining the state of the field interface thereof. The HART circuit includes a control interface, an adjustable power supply module, a first HART module, an isolation module, and a field interface. The first HART module is connected to the control interface. The first HART module is configured to generate a first control signal when receiving a first inquiry signal from the control interface. The adjustable power supply module is connected to the control interface and the first HART module. The adjustable power supply module is configured to output a first power signal to the control interface and, in response to the first control signal, modulate the first power signal into a first HART signal. A first terminal of the isolation module is connected to the control interface. The isolation module is configured to isolate a signal from the first terminal of the isolation module and couple the isolated signal to a second terminal of the isolation module. The field interface is connected to the second terminal of the isolation module.

摘要： In a power supply system, a single photocoupler can be used for two types of signal transmission. A switching power supply includes a first switching element connected between a primary winding of a transformer for the switching power supply and the ground, a shunt regulator serving as an output voltage detection circuit configured to detect an output voltage on a secondary winding side of the transformer, a photocoupler configured to transmit the output voltage to a control circuit, a second switching element configured to receive a stop signal for stopping operation of the switching power supply, and a photocoupler drive circuit configured such that when the second switching element has received the stop signal, power output from a low-frequency transformer power supply or the switching power supply is supplied to the photocoupler, and the stop signal is transmitted to the control circuit via the photocoupler.
