Background Technology

[0003] The vibration detection device detects vibration from the object to be detected and transmits the detected vibration signal to the server. The server analyzes the transmitted vibration signal and determines whether the vibration signal is a normal vibration signal or a vibration signal caused by a malfunction.

[0004] When the signal being analyzed is a signal caused by a leak, a vibration detection device is installed in the piping. Vibration detection devices are installed at one point and another point on the piping, respectively, and are spaced apart from each other by a predetermined distance. If a leak occurs in the piping between the one point and the other point, the vibration signal caused by the leak is transmitted to the vibration detection device installed at the one point and the vibration detection device installed at the other point, and the speed at which the vibration signal is transmitted varies depending on the location of the leak. The server calculates the location of the leak based on the difference in vibration signals transmitted from the separated vibration detection devices.

[0005] At this time, time synchronization between the vibration detection device at one point and the vibration detection device at another point is required to detect the accurate time difference. For time synchronization, the leak detection device receives a radio broadcast signal, modulates the radio broadcast signal with the vibration signal, and transmits it to the server. The modulated signal can utilize LTE communication.

[0006] The vibration detection device requires an antenna for receiving radio broadcast signals and an LTE communication antenna for transmitting modulated signals to a server.

[0028] The sensor antenna (100) is installed in a vibration sensor device. The sensor antenna receives a radio broadcast signal, modulates the radio broadcast signal and the detected vibration signal, and transmits them to a server.

[0029] The sensor antenna (100) includes a connection connector (110), a coaxial cable (120), a split space (130), a radio antenna (140), and an LTE antenna (150).

[0030] Referring to the drawing, the connection connector is installed at one end of the coaxial cable, and the split space is installed at the other end of the coaxial cable. A coaxial cable is connected between the connection connector and the split space, and a radio antenna and an LTE antenna protrude from the split space. The radio antenna line and the LTE antenna line are each electrically connected to a connection pin provided in the connection connector.

[0031] The sensor antenna is installed in a signal processing system. FIG. 1 is a configuration diagram of a signal processing system according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the sensor antenna according to the present invention installed in a vibration sensor device. The signal processing system detects a vibration signal caused by leakage from a pipe buried underground.

[0032] The signal processing system includes a first vibration sensor device (310), a second vibration sensor device (320), and a server (500). Sensor antennas are installed in the first vibration sensor device and the second vibration sensor device.

[0033] According to an embodiment, a first vibration sensor device (310) is installed at a first point (A) of a pipe (PP) buried underground, and a second vibration sensor device (320) is installed at a second point (B) spaced apart from the first point by a predetermined distance. The first point and the second point may be areas exposed above ground.

[0034] The first vibration sensor device and the second vibration sensor device are connected to a server via communication. The server receives a first signal and a second signal transmitted from the first vibration sensor device and the second vibration sensor device, respectively, and detects a leakage signal based on the first and second signals.

[0035] The first and second vibration sensor devices have the same internal structure. Hereinafter, the first vibration sensor device (310) and the second vibration sensor device (320) may be simply referred to as the vibration sensor device (300).

[0036] FIG. 3 is a configuration diagram of a vibration sensor device according to one embodiment of the present invention.

[0037] The vibration sensor device (300) may be configured to include a case, a vibration sensor (301) installed in the case, a receiver (302), a modulator (303), a transmitter (304), and a connection connector (305). Additionally, a battery may be further installed to provide power necessary for operating the vibration sensor, the modulator, the receiver, and the transmitter.

[0038] The vibration sensor detects vibration signals transmitted from the pipe. The detected vibration signal is input to the modulation unit. Additionally, the receiver is connected to a radio antenna and receives an over-the-air radio signal from the radio antenna. The received over-the-air radio signal is input to the modulation unit. The over-the-air radio signal may be an FM radio broadcast signal or an AM radio broadcast signal.

[0039] The modulation unit modulates the detected vibration signal and the received radio wave signal to generate a transmission signal. The transmission signal generated by the modulation unit is input to the transmitter, and the transmitter sends the transmission signal to the server via the LTE antenna. The server receives the transmission signal and demodulates it to obtain the radio wave signal and the vibration signal. After synchronizing the radio wave signal, the server calculates the time difference between the vibration signals.
