Generally, the current-triggered seismic surveying apparatus includes a trigger for informing the start point of the seismic wave collection, a plurality of water depth detectors for sensing the seismic wave, And a probe main body for collecting, monitoring, and storing the received elastic wave data.

Conventionally, a wired method using a trigger wire is adopted to transmit a trigger signal to the probe body in the trigger. In the conventional wired method, installation is not easy as the distance between the trigger and the main body of the probe is large, and when there is an obstacle such as a road or a building between the main body of the probe and the probe, the installation is not easy.

In view of such a problem, a device and a method for wirelessly transmitting and receiving a trigger signal have been proposed.

Korean Patent No. 10-063808 (Registered on Feb. 9, 2007) discloses a method and device for transmitting an acoustic wave generation signal in a seismic wave sensing to a receiving unit by remote wireless communication. A trigger signal for detecting the acoustic wave generation signal is transmitted to a remote And transmission through wireless communication is described.

More specifically, Korean Patent Registration No. 10-063808 discloses an acoustic wave generating signal detecting apparatus for detecting an acoustic wave generating signal and a wireless signal generating means for transmitting a wireless signal corresponding to an acoustic wave generating signal using an acoustic wave generating signal provided from the acoustic wave generating signal detecting apparatus And a wireless communication device for receiving a wireless signal, the wireless communication device comprising: a receiver for generating a trigger pulse signal when a received wireless signal corresponds to an acoustic wave generated signal; And a receiver control unit to which a signal is supplied.

A photocoupler is provided in the transmission unit. The photocoupler at this time informs the time when the elastic wave signal is detected and supplied. When a driving signal is applied by the photocoupler, a signal corresponding to a specific character is transmitted from the micom to the wireless communication transmitter .

The reception unit generates a trigger pulse signal when a signal corresponding to a specific character received through the wireless communication transmission apparatus is received, and upon receiving the generated trigger pulse signal, the reception unit control apparatus receives the first acoustic wave signal .

Although the above-mentioned patent describes that the trigger signal can be transmitted by 'remote wireless communication', a specific example of wireless communication is not described, and the 'remote wireless communication' Amplitude Modulation) and SSD (Single Side Band), there is a possibility that noise may be introduced due to surrounding facilities or components of the ground.

For example, in an environment where a high-voltage line passes, a high current region such as an industrial complex, or a region where minerals such as magnetite, iron ore, tourmaline, or coal are induced to change magnetic fields or electric fields, It may happen that the viewpoint can not be detected.

Another problem with the above patent is that it can not automatically detect the exact position of the trigger sensor that detects the trigger. The position of the trigger sensor indicates that the first seismic wave is detected at the corresponding position, which is an important factor in preparing the time and distance table for analyzing the section of the stratum. Conventionally, the user inputs the position information directly at the position of the trigger sensor There is a problem that the reliability is deteriorated.

In addition, since the body of the probe and the trigger sensor are far from each other and smooth communication is required between the workers on both sides, workers use a radio or a mobile phone to communicate with each other. However, There is a problem in that communication can not be smoothly performed due to the deterioration of the communication quality.

The tree rejection 100 is for detecting an initially generated seismic wave and transmitting the seismic wave detection point to the probe main body 200.

For this, the tree rejection unit 100 includes a trigger sensor unit 110 for detecting an elastic wave, a digital processing unit 120 for converting an analog trigger signal into a digital trigger signal, And a wireless digital transmission / reception unit 140 for transmission.

In addition, a GPS sensor 130 is included to detect the accurate position of the trigger sensor unit 110.

The trigger sensor unit 110 may use at least two of an accelerometer, a mercury switch, a pressure gauge, and a water depth detector, an accelerometer, a mercury switch, a pressure gauge, and a water depth detector.

When an acoustic wave is detected by the trigger sensor unit 110, the trigger sensor unit 110 generates an analog trigger signal, which is an analog current signal. The analog trigger signal is input to the digital processing unit 120 and converted into a digital trigger signal .

The digital processing unit 120 may convert the digital signal into a digital signal through a pulse generator or an encoder, or may generate and output a predetermined digital signal using a microprocessor. The above promised digital signal may be a digital signal of a specific length of '011010', and the reference time (O. Omsec) at which the elastic wave is initially received by the input of the digital trigger signal or the promised digital signal can be set.

Next, under the control of the controller 150, the current position information detected by the GPS sensor 130 is transmitted to the wireless digital transceiver 140 along with the digital trigger signal.

The wireless digital transceiver 140 converts the digital trigger signal and the position information data into a wireless digital communication signal in accordance with the set digital communication method and transmits the wireless digital communication signal.

Next, the wireless digital transmission / reception unit 210 provided in the probe main body unit 200 receives the wireless digital communication signal transmitted from the tree rejection unit 100, and transmits the digital trigger signal, which is two components of the received wireless digital communication signal, Separate location information data.

In the above configuration, the tree rejection 100 has only a function of wireless digital transmission, and the probe main body unit 200 can perform a desired operation even if it has only a wireless digital receiving function. However, It is preferable that the tree reject 100 and the probe main body 200 can transmit and receive wireless digital signals in both directions.
