Abstract
Description
Technical Field
[0001] The utility model relates to local equipment of a seismic exploration system, in particular to an independent storage time-interrupted signal receiver used in the seismic exploration system. Background Art
[0002] A telemetered digital seismograph is a seismograph that records remotely from an observation point via wired or wireless connections. It is commonly used in oil and gas exploration. For example, the 428XL fully digital network remote-controlled seismograph is a telemetered digital seismograph commonly used to detect whether there is oil and natural gas in the stratum.
[0003] In practical applications, remote digital seismographs and remote explosive devices together form a seismic exploration system, such as Figure 1 As shown, a traditional seismic exploration system includes a telemetered digital seismograph, a local remote detonator, and a remote remote detonator. The local remote detonator is located close to the telemetered digital seismograph, while the remote remote detonator is located farther away. The telemetered digital seismograph and the local remote detonator are connected by wired communication (alternatively, short-range wireless communication is used), while the local and remote remote detonators are connected by long-range wireless communication. During operation, the telemetered digital seismograph sends a command to the local remote detonator, which transmits the command information to the remote remote detonator. Upon receiving the command signal, the remote remote detonator generates a timer signal that directly reflects the quality of the data acquisition process and transmits the timer signal to the local remote detonator. The local remote detonator then transmits the timer signal to the telemetered digital seismograph. After receiving the returned timer signal, the telemetered digital seismograph proceeds to the next control step. Therefore, the timer signal is crucial to the entire seismic exploration system.
[0004] The defects of the above-mentioned traditional seismic exploration system are: the telemetry digital seismograph has a time window for receiving time-interruption signals. If the return time of the time-interruption signal exceeds the time window set by the telemetry digital seismograph, the telemetry digital seismograph will not be able to receive the time-interruption signal. In actual use, the remote detonator may have a time-interruption signal return time delay due to its own reasons or other human reasons. In this case, the telemetry digital seismograph cannot receive the time-interruption signal; at the same time, the telemetry digital seismograph can only receive time-interruption signals with the same acquisition parameters as its own, and cannot obtain time-interruption signals with smaller sampling intervals and higher accuracy, resulting in limited application; in addition, in actual applications, the telemetry digital seismograph sometimes gets stuck, in which case the telemetry digital seismograph cannot receive the time-interruption signal. Utility Model Content
[0005] The purpose of the present utility model is to provide an independent storage time-interrupted signal receiver for a seismic exploration system that can ensure time-interrupted signal reception in order to solve the above-mentioned problem.
[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0007] A standalone storage time-interrupt signal receiver for a seismic exploration system comprises a housing and a cover mounted on the housing, as well as a battery, a time-interrupt signal acquisition circuit, a clock synchronization circuit, a clock synchronization antenna, a storage circuit, and a memory card. The battery, the time-interrupt signal acquisition circuit, the clock synchronization circuit, and the storage circuit are each disposed within the housing. The clock synchronization antenna is mounted on the outer wall of the housing, the inner end of the clock synchronization antenna correspondingly connected to the clock synchronization circuit. A data input interface, a data output interface, and a data storage interface are provided on the outer wall of the housing. The inner end of the data input interface and the signal output end of the clock synchronization circuit are respectively connected to the signal input end of the time-interrupt signal acquisition circuit. The signal output end of the time-interrupt signal acquisition circuit is respectively connected to the input end of the storage circuit and the inner end of the data output interface. The memory card is mounted on the data storage interface and electrically connected to the output end of the storage circuit. The power output end of the battery is respectively connected to the power input end of the time-interrupt signal acquisition circuit, the clock synchronization circuit, and the storage circuit. Each of the aforementioned circuits refers to a circuit assembly or circuit module formed by mounting conventional resistor elements with related functions on a circuit board.
[0008] Preferably, in order to transmit the time-interrupt signal to the telemetry digital seismograph or other electronic devices of the user through wireless communication, the independent storage time-interrupt signal receiver for the seismic exploration system also includes a local wireless communication circuit and a local wireless communication antenna. The local wireless communication circuit is placed in the shell, the power input end of the local wireless communication circuit is correspondingly connected to the power output end of the battery, the signal input end of the local wireless communication circuit is connected to the signal output end of the time-interrupt signal acquisition circuit, and the signal output end of the local wireless communication circuit is connected to the inner end of the local wireless communication antenna. The local wireless communication antenna is installed on the outer wall of the shell and is parallel to the clock synchronization antenna. The local wireless communication antenna and the clock synchronization antenna are horizontally polarized antennas and vertically polarized antennas, respectively.
[0009] Preferably, according to actual needs, the local wireless communication circuit is a Wi-Fi communication circuit or a Bluetooth communication circuit, and the local wireless communication antenna is a Wi-Fi communication antenna or a Bluetooth communication antenna.
[0010] Preferably, in order to facilitate assembly and improve the isolation effect between the circuits, the shell is separated into multiple independent installation cavities by partitions, and the battery, the time-interrupt signal acquisition circuit, the clock synchronization circuit, the storage circuit and the local wireless communication circuit are respectively placed in the multiple installation cavities.
[0011] Preferably, in order to further improve the signal shielding effect of the intermittent signal acquisition circuit to avoid electromagnetic interference, the installation cavity where the intermittent signal acquisition circuit is located is installed with a Permalloy shielding cover.
[0012] Preferably, in order to facilitate the charging function, the battery is a rechargeable battery, a power interface is installed on the outer wall of the shell, and the inner end of the power interface is connected to the battery.
[0013] The beneficial effects of the present invention are:
[0014] The utility model integrates a battery, a time-interruption signal acquisition circuit, a clock synchronization circuit, the battery, the time-interruption signal acquisition circuit, the clock synchronization circuit, the storage circuit, and the storage circuit in a shell to form an independent power supply and independent storage time-interruption signal receiver. When in use, the time-interruption signal receiver is connected to a telemetered digital seismograph and a local remote detonator for corresponding communication. The time-interruption signal returned by the remote remote detonator can be independently received, and the analog time-interruption signal is processed (such as sampling, filtering and amplifying) by the time-interruption signal acquisition circuit to convert the tiny analog weak signal into a digital signal with obvious characteristics. The second pulse received by the clock synchronization circuit is Time information (such as GPS, Beidou and other satellite time information, which can be calibrated in real time to ensure the high precision of the synchronized time stamp) is sent to the time-interruption signal acquisition circuit to bind the time-interruption signal with the time stamp, and finally the time-interruption signal is saved in the memory card for the user to retrieve at any time. At the same time, the time-interruption signal is transmitted to the telemetry digital seismograph. This ensures that the time-interruption signal can be reliably received when the time-interruption signal is delayed, the time-interruption signal interval or accuracy does not match the telemetry digital seismograph, or the telemetry digital seismograph itself is stuck, avoiding the problem of serious impact on the entire seismic exploration system due to the inability to receive the time-interruption signal.
