The present invention is designed and manufactured so that seismic recorder and seismic sensor can be selected and combined regardless of the product (model), and correspond to three signal components such as east, west, north and south, and up and down directions detected from the seismic sensor. Design and manufacture the signal generator that generates the signal, and input the signal from the sensor cable to the seismic recorder and observe the positive or negative signal component shown in the seismic recorder to verify that the seismic sensor cable and seismic recorder are always operating normally. It relates to a device for checking whether or not.

Conventionally, the seismic sensor cable and the seismic recorder were separated and inspected. In the case of the seismic sensor cable, a multimeter was used to measure the resistance between the pins and the pins of the cable to check for short circuits. In this case, use a signal generator to connect the plus or minus signal to the seismic recorder's signal input to check whether the recorder is operating normally. When checking by the method of confirming the polarity of the recorded waveform by giving a shock, there is a problem that can damage the sensor, it takes a relatively long time. In addition, there is a problem that can damage the recorder when the signal component input during the inspection of the seismic recorder is too large or input the signal to the wrong pin number. There was a problem that it was impossible to purchase the manufacturer's product every time (the equipment should be installed and operated on site as soon as possible to observe the aftershock after the earthquake occurred) and it caused budget waste.

The technical problem to be achieved by the present invention was to recognize the problems of the prior art as described above, and to connect the recorder and the earthquake detection sensor to replace and operate a number of different equipment with each other, as described above Change the 12V voltage supplied from the seismic recorder into a 5V constant voltage source that is low enough to not damage the recorder, and use it to design and build a signal generator that can generate positive 5V or negative 5V. It is used as an input signal to check the normal operation of the sensor cable, and it can be connected to the cable connector to selectively check the three signal components representing the east, west, north and south directions that can be detected by the sensor. Plug in each signal using the signal generator And to export the negative signal to the seismic recorder recording system to quickly check the sensor cable and the normal operation of the seismic recording system, by configured such that it can be checked whether the correct response for each of the signal it is an object.

Prior to examining the configuration of the present invention, the seismic recorder and seismic sensor used for the earthquake research are to find the exact direction of the epicenter by measuring signals corresponding to three signal components such as east, west, north and south, and up and down directions. However, the important signal component in locating the epicenter by these three signals is the magnitude and polarity of the first one of the signals. The seismic recorder and seismic sensor cable must be checked at all times to ensure that the magnitude and polarity of the original signals of each of these signals can always be obtained without error. According to the present invention, a signal generator for generating signals corresponding to three signal components, such as east, west, north and south, and up and down directions detected from the earthquake sensor, regardless of the seismic recorder or the product (model) of the earthquake sensor. Design / fabrication and input the signal from the earthquake sensor cable to the earthquake recorder and check whether the earthquake sensor cable and the earthquake recorder are operating normally by observing the positive or negative signal component displayed on the earthquake recorder. Implement a device that can. More specifically, the constituent means for achieving the present invention, the signal generator for generating a signal necessary to check the seismic recorder is a voltage of 5V, which is low enough to not damage the recorder 12V voltage supplied from the seismic recorder The signal generator was designed / manufactured using 7805, a commercial electronic device that generates a 5V constant voltage source for use as a constant voltage source, and an input capable of checking a seismic recorder by generating a voltage of plus 5V or minus 5V. Make a check signal. In order to make a more stable check signal generator, high frequency components were filtered to remove noise, convert the signal to a desired size, and stabilize the signal by using a capacitor and a resistor to perform a stable operation. In addition, regardless of the product (model) of the seismic recorder and seismic sensor, the seismic recorder and seismic sensor cable fastening part (corresponding to the host and host shown in FIG. 2) can be connected to the cable. The seismic recorder and the earthquake sensor cable connection part and the earthquake recorder and the earthquake sensor cable that need to be inspected by the signal generator and the connector designed and manufactured above are designed. Connected. The signal generator includes an X terminal for transmitting signal components in the east-west direction to the seismic recorder, a Y terminal for transmitting signal components in the north-south direction to the seismic recorder, and a Z terminal for transmitting signal components in the vertical direction to the seismic recorder. The operator can easily select as needed to check each signal. The method of exporting the signal to the recorder for checking the seismic recorder and the seismic sensor cable includes first generating a positive 5V or a negative 5V from the signal generator and checking the seismic recorder and the seismic sensor cable in the east-west direction. To do this, lift up the X toggle switch on the front of the generator and the red LED will light up and a positive polarity signal will be sent to the recorder, and the recorder will display a positive component. When the light is on and a signal with negative polarity is transmitted to the recorder and a negative signal appears on the recorder, it means that the seismic recorder and earthquake sensor cable in the east-west direction are operating normally. The method of checking the seismic recorder and seismic sensor cable for the north-south direction and the up-down direction is carried out using the Y toggle switch in the north-south direction and the Z toggle switch in the up-down direction. Same as check for sensor cable. The structure that connects the seismic recorder and earthquake detection sensor cable designed / manufactured so as to be used regardless of the product (model) of the seismic recorder and the earthquake detection sensor (earthquake recorder and earthquake detection sensor cable connection part) is the The EPISENSOR earthquake detection sensor, CMG40T earthquake detection sensor, Q330 recorder and EPISENSOR earthquake detection sensor and CMG40 earthquake detection sensor are fastened to each other to have four different connector fastening structures according to the pin structure of the connector. Designed / manufactured. At this time, the LED is turned on by using the power signal from the recorder so that the connector can be always checked correctly. If the LED is lit, the connector is normally inserted.
