■ Functions
(1) Power mode switching
AC/DC switching: When the external power supply is disconnected, it can automatically switch to the built-in battery power supply to ensure that the device is powered on and data is continuously collected.
Signal feedback: When the battery is low or the charging power is disconnected, the power status signal can be sent to the mainboard in time.
(2) Power distribution
Multi-channel transmission: The different voltages (such as 12V, 5V) output by the power board are distributed to modules such as the display, sensor, and data processing unit.
Anti-interference design: Shielded cables reduce electromagnetic interference (EMI) and prevent signal noise from affecting the accuracy of fetal heart rate (FHR) monitoring.
(3) Safety protection
Protect the mainboard and power module, and disconnect when the current is abnormal (such as short circuit) to prevent abnormal current from damaging the mainboard and causing greater losses.
Physical protection: Wear-resistant outer skin design to prevent internal wires from being damaged by repeated bending or friction.

■ Common faults and diagnosis
(1) Fault phenomenon
1. The device still cannot be turned on after repeated power switching (power switching failure).
2. The device does not charge when connected to the power supply or the power display is abnormal.
3. The device intermittently powers off/restarts
4. The screen flickers or the sensor signal is unstable
(2) Diagnostic steps
Appearance inspection: Observe whether the cable sheath is damaged and whether the plug is oxidized or loose.
Power-on test: Check whether the wire is open or short-circuited.
Replacement test: Replace the same type of cable to check whether it is powered on.
■ Replacement steps
1. Disconnect the device power supply.
2. Open the device housing and locate the power switching cable (usually connecting the power board and the motherboard).
3. Record the original cable interface location, unplug the old cable and replace it with a new one.
4. Reassemble the device and test it.
