According to the daily broadcast and emergency broadcast switching circuit provided by the invention, an emergency control signal GPIOCTR from an emergency broadcast system control chip passes through a triode Q1 in a peripheral circuit of an analog switch U1, and then a GPIO signal is input to an IN1 pin of the analog switch U1; if the GPIOCTR is at a high level, the GPIO input to the IN1 pin is at a low level, and an audio signal passes through an NC channel, namely a rheostat RW1, so that adjustable output of volume is realized; if the GPIOCTR is at a low level, the GPIO which passes through the triode Q1 and then is input to the IN1 pin is at a high level, and an audio signal passes through an NO channel, so that a data signal received from the COM1 pin is directly output at the maximum volume; according to the application, the high level and low level switching of the GPIOCTR signal output by the control chip is matched with the analog switch U1, so that the switching of two broadcast modes can be accurately and quickly realized, and the daily broadcast and the emergency broadcast can be accurately processed and played.

This utility model relates to the field of pet equipment technology, specifically to a pet activity monitoring collar with a removable battery. Under normal circumstances, when the accelerometer detects that the collar is stationary and has been placed there for 10 minutes, the accelerometer will promptly transmit this detected state signal to the main control MCU. Upon receiving the signal, the main control MCU will immediately enter sleep mode, thereby reducing energy consumption and achieving energy saving. However, once the accelerometer senses that the collar has moved, it will immediately receive this dynamic change signal and quickly transmit the signal to the main control MCU, thereby controlling the main control MCU to start from sleep mode. After the main control MCU is awakened, it will activate the audio IC through its control function. When the audio IC is activated, it will output an analog signal to the speaker device, ultimately enabling the stored voice commands to be played clearly and accurately for further operation or command transmission.
