Seismic receiving devices are placed in the sea to receive artificial or natural seismic waves, monitor and record different types of seismic waves, and provide data for studying geographical information under the sea, understanding the ocean, developing seabed minerals, and studying seabed structures. However, the release success rate of existing seismic receiving devices is low, and some seismic receiving devices cannot be released and floated, which affects the recovery of seismic receiving devices and the collection of data. Summary of the invention

[0003] The main purpose of the embodiments of the present application is to propose a release method, system, electronic device and storage medium for a seismic receiving device to improve the release success rate of the seismic receiving device.

[0008] If the power level of the release power supply is lower than the set power threshold, the acquisition power supply in the seismic receiving device is called to drive the constant current source circuit to output current, so as to blow the fuse connected between the cathode and anode of the constant current source circuit, thereby disconnecting the release mechanism from the counterweight block.

[0027] In response to the timed release instruction, the step of obtaining the power level of the release power supply in the seismic receiving device is executed, and it is determined whether the power level is lower than a set power threshold.

[0028] In some embodiments, before obtaining the power of the release power supply in the seismic receiving device in response to the hydroacoustic release instruction and determining whether the power is lower than a set power threshold, the method further includes the following steps:

[0030] When the count value of the timer is equal to the waiting time, the response to the hydroacoustic release instruction is executed to obtain the power of the release power supply in the seismic receiving device, and determine whether the power is lower than the set power threshold.

[0031] In some embodiments, the method further comprises the following steps:

[0032] receiving and responding to a stop release instruction, controlling the constant current source circuit to stop outputting current;

[0033] Alternatively, when it is detected that the external power source is connected, the constant current source circuit is controlled to stop outputting current.

[0034] To achieve the above object, another aspect of the embodiment of the present application provides a release system for a seismic receiving device, the system comprising:

[0055] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Depending on the context, the words "if" and "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determination".

[0057] The terms "at least one", "multiple", "each", "any", etc. used in this application, at least one includes one, two or more, multiple includes two or more, each refers to each of the corresponding multiple, and any refers to any one of the multiple.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0059] Before describing the embodiments of the present application in detail, some terms and related technologies that may be involved in the embodiments of the present application are first described. The following explanations apply to some terms and related technologies in the embodiments of the present application:

[0060] Fusing: The process in which a metal sheet (wire) is disconnected after a current is passed through the metal sheet (wire) in a seawater electrolyte environment, accelerating the electrolytic chemical reaction.

[0061] Ionization: Chemical ionization refers to the process in which electrolytes dissociate into oppositely charged and freely moving ions in aqueous solution or molten state. There are two types of ionization in aqueous solution: complete ionization and incomplete ionization. Strong electrolytes are completely ionized in aqueous solution, while weak electrolytes are incompletely ionized in aqueous solution.

[0062] Electrolysis: Electrolysis is the process in which anions and cations in an electrolyte solution move to the two poles and undergo redox reactions after electricity is applied.

[0063] The vast ocean provides humans with abundant food and mineral resources, but also brings disasters such as earthquakes, volcanic eruptions and tsunamis. Seismic receiving devices are placed in the sea to receive artificial or natural seismic waves, monitor and record different types of seismic waves, and provide data for studying geographical information under the sea, understanding the ocean, developing seabed minerals, and studying seabed structures. However, the release success rate of existing seismic receiving devices is low, and some seismic receiving devices cannot be released and floated, which affects the recovery of seismic receiving devices and the collection of data.

[0064] The seismic receiving device can monitor and record different types of seismic waves. The seismic receiving device may include: an acoustic acquisition module, a release module, a power module, a positioning module, a buoyancy module, a protection module, a sinking weight module, etc. Among them, the release module may include an electric control part and a mechanical structure part, and the release mode includes a timed release and an acoustically controlled release. The embodiment of the present application may adopt a dual power supply, a dual release mode, and release by receiving a control command through a hydrophone to improve the release success rate.

[0065] The prior art has the following problems:

[0066] 1. The release failed due to insufficient power, single-channel release failure, or the acoustic collection module failed to receive the release command normally.

[0067] 2. There is a deep-sea crosstalk problem: the coupling, mutual inductance and mutual capacitance between the signal ground of the seismic receiving device and the seawater ground cause noise on the ground line. Capacitive coupling causes coupling current, while inductive coupling causes coupling voltage. There is a crosstalk problem to the ground, and the fuse cannot be completed, resulting in unsuccessful release.

[0068] In order to solve at least one problem existing in the prior art, the embodiments of the present application provide a release method, system, electronic device and storage medium for a seismic receiving device. The technical solution of the present application includes: collecting water acoustic signals, identifying water acoustic signals to obtain water acoustic release instructions; in response to the water acoustic release instructions, obtaining the power of the release power supply in the seismic receiving device, and judging whether the power is lower than the set power threshold; if the power of the release power reaches the set power threshold, calling the release power to drive the constant current source circuit to output current to melt the fuse connected between the cathode and anode of the constant current source circuit, so that the release mechanism is disconnected from the counterweight; if the power of the release power is lower than the set power threshold, calling the acquisition power in the seismic receiving device to drive the constant current source circuit to output current to melt the fuse connected between the cathode and anode of the constant current source circuit, so that the release mechanism is disconnected from the counterweight. In this embodiment, the release power or the acquisition power can be called to drive the constant current source circuit to output current for fusing. When the release power is insufficient, the acquisition power can be called to supply power; and the constant current source circuit can output a constant current, which improves the success rate of fuse release.

[0069] Reference Figure 1 The embodiment of the present application provides a method for releasing a seismic receiving device, which may include but is not limited to S100 to S130, as follows:

[0070] S100: Collecting an underwater acoustic signal, and identifying the underwater acoustic signal to obtain an underwater acoustic release instruction.

[0071] It is understandable that when the seismic receiving device is in the seawater, it can collect the hydroacoustic signal in the seawater and determine whether the hydroacoustic signal is a hydroacoustic release instruction.

[0072] Furthermore, this embodiment provides an optional seismic receiving device, the structure of which is as follows: Figure 2 shown.

[0073] Figure 2 The structure shown can be placed in a sealed glass ball. The density of the entire ball is less than that of seawater, and the ball can be suspended in seawater or float on the sea surface.

[0074] The transducer and the hydrophone are connected to the acoustic signal decoding circuit of the release control board, the acquisition power supply and the release power supply are connected to the power control circuit of the release control board, and the release mechanism is connected to the anode and cathode of the constant current source circuit of the release control board through the release line. The release mechanism is connected to the counterweight block, which can keep the seismic receiving device in the seawater and sink to the seabed to receive seabed seismic signals.

[0075] Therefore, collecting the water acoustic signal may further include:

[0076] Collecting a first hydroacoustic signal by means of a transducer in the seismic receiving device;

[0077] Alternatively, the second hydroacoustic signal is collected by a hydrophone in the seismic receiving device.

[0078] Add a hydrophone to monitor the water acoustic release command. When the transducer cannot obtain the water acoustic release command normally, the hydrophone can be used to receive the water acoustic release command and complete the release, thereby improving the release success rate.

[0079] In addition, before collecting the water acoustic signal, the embodiment of the present application may further include:

[0080] The anti-interference circuit in the seismic receiving device is used to remove the received noise signal.

[0081] This embodiment can solve the problem of ground crosstalk, ensure that the fuse release is completed normally, and improve the release success rate.

[0082] Furthermore, identifying the underwater acoustic signal to obtain an underwater acoustic release instruction may include:

[0083] The first hydroacoustic signal is filtered and decoded in sequence by using an acoustic signal decoding circuit in the seismic receiving device to obtain a first device code and a first command code; if it is detected that the first device code is consistent with the local device code, and the first command code is a release command code, the first hydroacoustic signal is identified as the hydroacoustic release command;

[0084] Alternatively, the acoustic signal decoding circuit is used to perform limiting amplification, bandpass filtering and decoding on the second underwater acoustic signal in sequence to obtain a second device code and a second command code; if it is detected that the second device code is consistent with the local device code, and the second command code is a release instruction code, the second underwater acoustic signal is identified as the underwater acoustic release instruction.

[0085] Specifically, the onboard deck machine can send a hydroacoustic release command, which is converted into an acoustic signal and transmitted to the seabed through the seawater. The transducer and the hydrophone receive the acoustic signal transmitted through the seawater, and the acoustic signal is decoded by the acoustic signal decoding circuit to identify whether the decoding result is a hydroacoustic release command.

[0086] Among them, the frequency range of the water acoustic signal collected by the hydrophone is relatively wide.

[0087] The transducer can be used for underwater acoustic communication. The signal frequency range is relatively narrow. After receiving the signal, filtering can be performed to achieve the purpose of anti-interference. In the case of transducer communication failure, a hydrophone can be used to receive the signal, and the underwater acoustic communication instructions can be received by software filtering. The acoustic decoding circuit first performs limiting amplification, and then performs bandpass filtering. The filtered signal software is judged, and the decoded data is the control command code.

[0088] The decoded data includes the device code and the command code. If the decoded device code is consistent with the local device code of the seismic receiving device, it means that the seismic receiving device is controlled. The command code includes the release command code, the stop release command code and the status query command code. If the command code is consistent with the release command code, it is a release command.

[0089] S110: In response to the hydroacoustic release instruction, the power level of the release power supply in the seismic receiving device is obtained, and it is determined whether the power level is lower than a set power threshold.

[0090] It can be understood that in order to determine whether the power of the released power source meets the fuse release condition, this embodiment can detect and determine the remaining power of the released power source.

[0091] Further, refer to Figure 3 , obtaining the power of the released power supply in the seismic receiving device, including S111 to S113:

[0092] S111: acquiring the voltage of the release power supply as a sampling voltage through an analog-to-digital conversion circuit;

[0093] S112: Substituting the sampled voltage into a voltage calculation formula to calculate the voltage of the released power supply;

[0094] S113: determining the amount of power of the released power source according to the voltage of the released power source;

[0095] The voltage calculation formula is:

[0096] V VCC =(R+10K) / R×V ADC ;

[0097] Among them, V VCC is the voltage of the release power supply, R is the resistance, K is, V ADC is the sampling voltage.

[0098] In addition, before S110, the embodiment of the present application may further include:

[0099] S101: Set the waiting time and start the timer to count;

[0100] When the count value of the timer is equal to the waiting time, the response to the hydroacoustic release instruction is executed to obtain the power of the release power supply in the seismic receiving device, and determine whether the power is lower than the set power threshold.

[0101] It can be understood that the timer counts the remaining time, and when the counting stops, that is, the current time is the set timing time, the release operation process can be started.

[0102] In this embodiment, a timed release can be set before responding to the underwater sound release command to release the fuse, so that after a certain period of time, the fuse is released in response to the underwater sound release command. The overall step flow can be referred to Figure 4 .

[0103] S120: If the power of the release power source reaches the set power threshold, the release power source is called to drive the constant current source circuit to output current to blow the fuse connected between the cathode and anode of the constant current source circuit, so that the release mechanism is disconnected from the counterweight.

[0104] S130: If the power level of the release power supply is lower than the set power threshold, the acquisition power supply in the seismic receiving device is called to drive the constant current source circuit to output current, so as to blow the fuse connected between the cathode and anode of the constant current source circuit, thereby disconnecting the release mechanism from the counterweight block.

[0105] For ease of understanding, an overall description of S120 and S130 is given below:

[0106] After receiving the hydroacoustic release command, the seismic receiving device can start the release operation process. After the release operation is started, it is judged whether the power of the release power supply meets the release. If the power meets the release power supply, the release power supply is used. If the power does not meet the release power supply, the acquisition power supply is used. The power of the release power supply can be judged according to the voltage. When the voltage of the release power supply is lower than the set voltage threshold, it is considered that the remaining power is insufficient. The set voltage threshold can be determined according to the maximum working voltage and total power of the release power supply. The release power supply is mainly used for release. The function of the acquisition power supply is mainly to supply power when the hydrophone and the transducer collect hydroacoustic signals. The purpose of setting two power supplies can improve the success rate of fuse release, and the release process has less impact on the collected hydroacoustic signals. The release power supply basically does not consume electricity during the process of collecting hydroacoustic signals, making the sending and receiving of the release command more reliable. During the release process, the release power supply will not affect the acquisition power supply. When the power of the release power supply is insufficient, the acquisition power supply can continue to provide power as a backup power supply, so that the fuse release can proceed normally, which can improve the recovery rate of the seismic receiving device.

[0107] After the power supply is selected, the constant current source circuit is driven to output a constant current to blow the fuse. After the fuse is blown, the release mechanism automatically unhooks and separates from the counterweight block. The release mechanism and the seismic receiving device float to the sea surface for recovery.

[0108] The embodiment of the present application can improve the release success rate by using dual power supplies. When one power supply is insufficient, the other power supply is started to perform fuse release. A constant current source circuit outputs a stable fuse current, thereby improving the fuse release success rate.

[0109] In addition to actively receiving the underwater sound release command to perform fuse release, the embodiment of the present application can also realize timed fuse release, that is, the embodiment of the present application can also include the step of setting a timed release command, including S141~S143. The overall step flow can refer to Figure 5 .

[0110] S141: Setting the timing release time;

[0111] S142: Calculate the difference between the timer release time and the current time;

[0112] S143: Start the timer to count;

[0113] When the count value of the timer is equal to the difference, the embodiment of the present application further includes:

[0114] S144: In response to the timed release instruction, the step of obtaining the power level of the release power supply in the seismic receiving device is executed, and determining whether the power level is lower than a set power threshold.

[0115] Exemplarily, both the count of the timer and the difference value may be calculated using seconds as a unit.

[0116] By setting a timed release instruction, the fuse release can be completed when the seismic receiving device cannot receive the hydroacoustic release instruction, thereby improving the release success rate.

[0117] The embodiment of the present application may further include the step of stopping the release:

[0118] receiving and responding to a stop release instruction, controlling the constant current source circuit to stop outputting current;

[0119] Alternatively, when it is detected that the external power source is connected, the constant current source circuit is controlled to stop outputting current.

[0120] Exemplarily, the deck machine sends a stop release command to the seismic receiving device. After receiving the stop release command, the seismic receiving device can control the constant current source circuit to stop outputting current; or, when the seismic receiving device detects that it is connected to an external power supply, it can control the constant current source circuit to stop outputting current.

[0121] Next, the solution of the embodiment of the present application will be described in detail and explained in conjunction with specific application examples:

[0122] Reference Figure 6 , this embodiment provides an example flow chart of a release method of a seismic receiving device.

[0123] Specifically, this embodiment may include the following steps:

[0124] Step 1: Set the timer release time, and save the timer time to the internal storage medium of the seismic receiving device;

[0125] Before launching the seismic receiving device, it is necessary to set the specific timed release time in the form of year, month, day, hour, minute, and second. The timed release time is compared with the current time to obtain the total number of seconds of the two time differences and save it to the internal storage medium. At the same time, the second-level timer is started to count. When the count value is equal to the total number of seconds stored, it is determined that the timed release time has been reached.

[0126] T1: current time, T2: release time.

[0127] The sample code is as follows:

[0128] T1 = time(null);

[0129] DT=difftime(T2,T1).

[0130] Step 2: The transducer receives an underwater acoustic release command, or the hydrophone receives an underwater acoustic release command, and sets a timed release time to start a release operation.

[0131] Set two frequencies f1 and f2. If the received signal frequency meets f1, it represents bit0, and if it meets f2, it represents bit1. The device code consists of two bytes, a total of 16 bits, and the command code consists of 2 bytes, a total of 16 bits. There is also 1 XOR check bit, which uses XOR check. Decode the hydroacoustic signals received by the transducer or hydrophone respectively in the above manner to obtain 33 bits of data, and if the verification passes, the device code and command code are obtained. When the decoded device code is consistent with the local device code, and the command code is a release command code, the release operation is started. The device code and release command code in the hydroacoustic release command can be configured through the host computer.

[0132] Step 3: Start the release operation.

[0133] Determine whether a timer is started for the release operation. If so, wait until the count stops and then go to step 4. If not, go directly to step 4.

[0134] Step 4: Check and release the power supply.

[0135] The voltage of the release power supply is obtained by the ADC (analog-to-digital conversion circuit) on the release control board. The sampled voltage obtained by ADC sampling is V ADC , the voltage of the released power supply is obtained by the following calculation formula:

[0136] V VCC =(R+10K) / R×V ADC ;

[0137] Among them, V VCC To release the voltage of the power supply, R is the resistor, K is, V ADC is the sampling voltage.

[0138] The amount of power released is then determined based on the power supply of the released voltage.

[0139] Step 5: If the power of the released power source reaches the set power threshold, the released power source is used for fuse release; if the power of the released power source is lower than the set power threshold, the collected power source is used for fuse release.

[0140] When the power of the released power reaches the set power threshold, the collection power relay is closed and the release power relay is opened. When the power of the released power is lower than the set power threshold, the release power relay is closed and the collection power relay is opened.

[0141] Step 6: Add an anti-interference circuit to drive the constant current source circuit to fuse.

[0142] The constant current source circuit outputs a constant fusing current, which is energized to the fuse connected to the cathode and anode of the release mechanism. The fuse in the seawater produces an electrolytic reaction under the action of the energization and melts in the seawater. The constant current source circuit can stably output a fusing current greater than 1000mA in seawater.

[0143] Step 7: The fuse is blown and the release mechanism is unhooked and released.

[0144] After the fuse is blown, the release mechanism is unhooked under the gravity of the counterweight block, and the seismic receiving device floats to the sea surface under the buoyancy of seawater, waiting to be recovered.

[0145] Step 8: Stop releasing.

[0146] After the seismic receiving device is recovered, it can be stopped and released in two ways:

[0147] 1. Send a stop release command through the deck machine to stop the release;

[0148] 2. Connect an external power source to the seismic receiving device to stop the release.

[0149] This embodiment realizes fuse release by combining the electronic control part and the mechanical structure part, and realizes dual power supply release, timed release and acoustic release coexist, uses two sensors, hydrophone and transducer, to simultaneously receive hydroacoustic release instructions, and combines chemical fusing with mechanical uncoupling to achieve a high success rate of release.

[0150] This embodiment adopts the following technical means:
