Water supply system capable of detecting faucet malfunction using water flow rate

A water supply system, comprising:

• a sensor faucet comprising an infrared sensor, an electromagnetic valve for turning on or shutting off water supply, and a fault indication unit;
• a water flow rate sensor configured between the electromagnetic valve and a water outlet of the sensor faucet to detect a water flow rate and a water flow duration of the sensor faucet;
• and
• a processing unit electrically connected to the electromagnetic valve;
• wherein data of the water flow rate and the water flow duration transmitted by the water flow rate sensor to the processing unit;
• the processing unit analyses the data;
• when the water flow rate is normal and the electromagnetic valve operates properly, the processing unit determines that the sensor faucet is functioning correctly;
• if the water flow rate does not meet a set value or the water flow duration exceeds a preset time, and the infrared sensor of the sensor faucet detects activity but no water is discharged, the processing unit determines that the sensor faucet is faulty;
• and, the processing unit generates a signal to the fault indication unit, which generates a fault alert for a management personnel.
