Patent attributes
A signal monitoring system includes four sensors, a multiplexer, a signal converting circuit, and a monitor chip. The multiplexer is electrically connected to the sensors for receiving the signals from the sensors. The multiplexer includes two selecting ports for selecting one of the sensors to communicate with the multiplexer, and a data bus for transmitting the signals generated by the selected sensor. The signal converting circuit includes an ADC electrically connected to the multiplexer for converting analog signals output therefrom to digital signals, and an MCU electrically connected to the ADC and the multiplexer. The MCU includes a digital port electrically connected to the monitor chip for outputting digital signals thereto, and a timer electrically connected to the monitor chip for outputting pulse signals thereto. The monitor chip is for processing the digital signals or pulse signals. A related signal monitoring method is also disclosed.
