Abstract

A water leak sensor management method includes a water leak sensor being installed in a underground pipe. The method includes detecting an operation time of the water leak sensor through a timer in a sleep mode, changing the sleep mode into a standby mode in the operation time of the water leak sensor to detect a sensor measuring procedure, and performing an operation for a transceiving component of the water leak sensor and determining whether the water leak sensor receives an external command or changes the standby mode into an operation mode based on the sensor measuring procedure.

Claims

1. A method for managing a water leak sensor coupled to a pipe, the method comprising:

detecting an operation time of the water leak sensor that is in a sleep mode;

causing the water leak sensor to change from the sleep mode to a standby mode according to the detected operation time;

detecting a sensor measuring procedure when the water leak sensor changes to the standby mode;

performing an operation for a transceiving component of the water leak sensor based on the detected sensor measuring procedure; and

determining whether the water leak sensor receives an external command or changes from the standby mode into an operation mode based on the detected sensor measuring procedure.

2. The method of claim 1, wherein while the water leak sensor is in the sleep mode, the method further comprises:

supplying power to a real time clock (RTC) while the water leak sensor blocks power to the transceiving component.

3. The method of claim 1, wherein while the water leak sensor is in the sleep mode, the method further comprises:

providing battery status of the water leak sensor to a control server when a battery level of the water leak sensor is less than a threshold level, wherein the battery status causes the control server to adjust the operation time of the water leak sensor.

4. The method of claim 1, further comprising:

supplying power to the transceiving component when the operation time of the water leak sensor is detected.

5. The method of claim 1, further comprising:

waiting, during a specific time interval, for the receiving of the external command when the sensor measuring procedure operates as a manual mode.

6. The method of claim 5, further comprising:

performing a shutdown on the transceiving component when the external command is not received and changing from the standby mode to the sleep mode.

7. The method of claim 5, further comprising:

changing from the standby mode to the operation mode to initiate supply of power to a sound sensing component when the external command is received.

8. The method of claim 7, wherein the external command corresponds to at least one of a water leak sound data collection command, a water pressure data collection command, and a flow velocity data collection command for the pipe.

9. The method of claim 8, further comprising:

obtaining data relating to the pipe according to the external command;

transmitting a digital signal to a control server through an antenna, wherein the digital signal corresponds to the obtained data; and

blocking power to the sound sensing component after the transmitting of the digital signal; and

changing the operating mode to the sleep mode when the blocking of the power to the sound sensing component is not completed after a specific time.

10. The method of claim 1, further comprising:

changing from the standby mode to the operation mode when the sensor measuring procedure operates as an automatic mode and analyzing a batch file predetermined by a user to start to supply power to an operation component related to the batch file, and

wherein the operation component corresponds to a sound sensing component.

11. The method of claim 10, further comprising:

sensing vibration of a sound wave of the pipe through an acceleration sensor of the sound sensing component during the operation mode; and

outputting an electric charge corresponding a vibration level of the sensed vibration.

12. The method of claim 11, further comprising:

converting the electric charge into a voltage and amplifying the voltage via an amp of the sound sensing component.

13. The method of claim 12, further comprising:

transmitting a digital signal to a control server through an antenna, wherein the digital signal corresponds to the amplified voltage; and

blocking power to the sound sensing component after the transmitting of the digital signal; and

changing from the operating mode to the sleep mode when the blocking of the power for the sound sensing component is not completed after a specific time.

14. The method of claim 1, wherein the pipe is underground.

16. The water leak sensor of claim 14, wherein while the water leak sensor is in the sleep mode, the operation time detecting unit is further configured to supply power to a real time clock (RTC) while the water leak sensor blocks power to the transceiving component.
