Description
Technical Field

[0002] With the rapid development of geophysical exploration technology, the challenges faced by seismic exploration operations are increasing day by day. In particular, the complexity of the surface of the exploration work area has increased significantly, posing higher requirements for the acquisition equipment in field construction. In most irregular three-dimensional exploration operations, due to the irregularity of the layout, the demand for power stations has increased sharply, and the supply of existing power stations often cannot meet the demand, making the problem of insufficient power stations more prominent.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.
[0033] In related seismic data acquisition systems, in order to efficiently and accurately capture information on underground geological structures, ground electronic devices of multiple seismic exploration instruments, namely field data acquisition units (abbreviated as acquisition stations), are set up. They are arranged on a predetermined ground and are interconnected through physical lines to form closely collaborating arrays (i.e., secondary arrays).
[0034] To support the normal operation of these acquisition stations, a power station is also set up in the system. As the center of energy supply, the power station is responsible for providing necessary electrical energy to each acquisition station. They are usually deployed at key positions in the array, and one is set up every certain number of acquisition stations to ensure stable and reliable power supply for the entire array.
[0035] When the system needs to cover a wider area or perform more complex exploration tasks, multiple secondary arrays are set up. Data aggregation and exchange between these arrays are achieved through cross stations. As the hub of data transmission, the cross station can receive data from acquisition stations in different arrays and integrate and transmit it to the instrument vehicle.
[0036] The instrument vehicle, as the control center of the entire seismic data acquisition system, is responsible for collecting data from each array and cross station and performing functions such as data storage, preliminary processing, and analysis.
[0037] However, with the rapid development of geophysical exploration technology, the surface of the current seismic exploration work area is becoming increasingly complex, and the usage of acquisition equipment in field construction has increased significantly compared to before. Especially during the construction of most irregular three-dimensions, due to the irregular array, more power stations are required, and the problem of insufficient power stations is more prominent.
[0038] Therefore, some field exploration teams have tried to adopt non-standard solutions, that is, using cross stations and power stations of other models or series to replace the power station functions of the original design. Although this method alleviates the urgent need for equipment shortage to a certain extent, its side effects are also obvious: it limits the data transmission rate, especially the transmission rate of the secondary array is limited to a relatively low level, thus seriously affecting the channel-carrying capacity of the power station and unable to fully exert the performance advantages of advanced seismic exploration equipment.
[0039] Specifically, some field teams use the cross - station and power - station of 408UL to replace the function of the 428XL power - station for construction operations to solve the problem of insufficient 428XL power - station equipment. However, in such a mixed - use situation, the transmission rate of the secondary array can only run at 8 Mbps, which severely restricts the channel - carrying capacity of the power - station and cannot maximize the advanced performance of the 428XL instrument. At the same time, it also affects the construction efficiency of the seismic - data acquisition project.
[0040] In view of this, an embodiment of the present application provides a device for enhancing the channel - carrying capacity of a seismic exploration instrument.
[0041] As Figure 1 - Figure 2 shown, a device for enhancing the channel - carrying capacity of a seismic exploration instrument includes: a boost module, and the boost module is used to boost the voltage of the accessed power supply.
[0042] Specifically, the enhancement device is arranged in the secondary array, and the direct external power supply (a 12 - V battery) of the enhancement device is then connected to other devices in the secondary array. Therefore, when in use, the enhancement device can be regarded as a power - station.
[0043] Among them, the boost module includes a boost circuit 1 and a hot - swap interface. The boost circuit 1 can boost the 12 - V voltage to 24 - V voltage. The boost circuit 1 is connected to the power supply through the hot - swap interface. The hot - swap interface has at least two. The two hot - swap interfaces can ensure that the device will not lose its effect when replacing the battery. The boost circuit 1 adopts a PWM (Pulse Width Modulation) power - supply design. The PWM power - supply has the characteristics of stable output voltage, fast response speed, strong anti - interference ability, and strong noise - resistance ability, and is suitable for complex field seismic - data acquisition scenarios.
[0044] Specifically, when in use, the battery is connected to the boost circuit 1 through a hot - swap interface. When the battery runs out of power and needs to be replaced with a new one, the output terminal of the new battery can be directly inserted into the idle hot - swap interface on the boost circuit 1. Then, the battery with insufficient power is pulled out to complete the replacement of the battery. During this process, the power supply to the enhancement device will not disappear, so that replacing the battery will not affect the use of the enhancement device. It ensures that the acquisition operation will not be interrupted due to replacing the battery. After the voltage of the battery is boosted by the boost circuit 1, the boost circuit 1 delivers the power to the self - locking circuit 2.
[0045] Specifically, the input end of the self - locking circuit 2 is connected to the boost module, and the self - locking circuit 2 is used to control the output of the power supply boosted by the boost module.
[0046] After the voltage of the storage battery is boosted by the boost circuit 1, it is transmitted by the boost circuit 1 to the self-locking circuit 2. Subsequently, the self-locking circuit 2 transmits the power to the device interface 3, and the device interface 3 is used to connect the seismic exploration instruments in the secondary array. And since the enhancement device is installed in the secondary array, at least two such device interfaces 3 need to be provided to connect the second array. To meet the requirements of connecting to multiple device interfaces 3 respectively, the self-locking circuit 2 includes multiple output terminals, and at least two device interfaces 3 are connected to different output terminals of the self-locking circuit 2, that is, each device interface 3 is connected to an output terminal of the self-locking circuit 2.
[0047] In the seismic data acquisition system, the power supply station supplies power unilaterally. Each power supply station takes itself as the starting point and supplies power in one direction in the secondary array, and the power supply directions of each power supply station are the same (mostly starting from the instrument vehicle and supplying power in the direction away from the instrument vehicle in the secondary array), so as to connect with each other to form a complete power supply chain. Therefore, it is necessary for the self-locking circuit 2 to control the power supply to the device interface 3 through the opening and closing of itself and each device interface 3. That is, only the direction of the device interface 3 connected to the self-locking circuit 2 will be powered. Thus, the power supply direction is controlled.
[0048] In order to judge the direction where the instrument vehicle is located, so as to ensure that the power supply direction of the enhancement device is the same as that of other power supply stations and supply power in the direction away from the instrument vehicle. The enhancement device is also provided with a logic judgment circuit 4 to judge the direction where the instrument vehicle is located. The output terminal of the logic judgment circuit 4 is connected to the self-locking circuit 2, and the input terminal of the logic judgment circuit 4 is connected to the device interface 3. And the logic judgment circuit 4 includes multiple input terminals, and at least two device interfaces 3 are connected to different input terminals of the logic judgment circuit 4. The logic judgment circuit 4 is used to control the disconnection of the self-locking circuit 2 and the device interface 3 according to the power-on signal input by the device interface 3.
[0049] That is, each device interface 3 is respectively connected to different input terminals of the logic judgment circuit 4, so that the logic judgment circuit 4 can distinguish each different device interface 3.
[0050] Specifically, during operation, the instrument vehicle sends a power-on signal to the secondary array to start each device. When the power-on signal is transmitted to one of the device interfaces 3 of the enhancement device, the power-on signal is transmitted from this device interface 3 to the logic judgment circuit 4. After receiving the power-on signal transmitted from this device interface 3, the logic judgment circuit 4 sends an instruction to the self-locking circuit 2 to disconnect the self-locking circuit 2 from the device interface that transmitted the power-on signal, so that the self-locking circuit 2 does not supply power to the device interface that transmitted the power-on signal. Then, the self-locking circuit 2 supplies power to other device interfaces that have not received the power-on signal and supplies power to the acquisition stations in the direction away from the instrument vehicle.
[0051] Specifically, in an alternative embodiment, there are two device interfaces 3, and the two device interfaces 3 include a first interface and a second interface. The logic judgment circuit 4 is configured to control the disconnection of the self-locking circuit 2 from the first interface and maintain the connection between the self-locking circuit 2 and the second interface according to the power-on signal input from the first interface. Alternatively, the logic judgment circuit 4 is configured to control the disconnection of the self-locking circuit 2 from the second interface and maintain the connection between the self-locking circuit 2 and the first interface according to the power-on signal input from the second interface.
[0052] Specifically, when the power-on signal appears at the first interface, the first interface transmits the power-on signal to the logic judgment circuit 4. After receiving the power-on signal transmitted from the first interface, the logic judgment circuit 4 sends an instruction to disconnect from the first interface to the self-locking circuit 2. The connection between the self-locking circuit 2 and the first interface is disconnected, and the self-locking circuit 2 does not supply power to the first interface. The power supply direction locking function is realized.
[0053] When the power-on signal appears at the second interface, the second interface transmits the power-on signal to the logic judgment circuit 4. After receiving the power-on signal transmitted from the second interface, the logic judgment circuit 4 sends an instruction to disconnect from the second interface to the self-locking circuit 2. The connection between the self-locking circuit and the second interface is disconnected, and the self-locking circuit 2 does not supply power to the second interface.
[0054] Further, in order to adapt to the existing ground electronic equipment of seismic exploration instruments, the device interface 3 is an integrated port that can supply power and transmit data simultaneously, so that the device interface 3 can supply power and transmit information simultaneously.
[0055] Further, in order to process and transmit the information passing through the enhancement device, the enhancement device is provided with a data transmission circuit 6. The data transmission circuit 6 is connected to the device interface 3, and the data transmission circuit 6 is used to transmit the data collected by the seismic exploration instrument. Among them, the data transmission circuit 6 uses a 10 / 100M digital signal transmission transformer with a 1:1 transmission ratio, which minimizes signal distortion and reduces signal loss. The data transmission rate reaches 100 Mbps and is compatible with transmission rates of 8 Mbps and 16 Mbps.
[0056] Since the channel capacity of the power station is increased, the arrangement length between two power stations is increased (after increasing the channel capacity, more acquisition stations can be directly set between two power stations). In a complex construction environment, especially during thunderstorm weather, induced current is likely to be formed, causing extensive damage to ground electronic equipment. Therefore, the enhancement device is provided with at least two isolation circuits 5, and the isolation circuits 5 are connected to the corresponding device interfaces 3. That is, each device interface 3 is correspondingly connected to an isolation circuit 5. The isolation circuit 5 is used to limit the current passing through the enhancement device.
[0057] Specifically, in the connection between the self-locking circuit 2 and the device interface 3, the self-locking circuit 2 is first connected to the first input end of the isolation circuit 5 and then connected to the device interface 3 from the first output end of the isolation circuit 5.
[0058] In the connection between the logic judgment circuit 4 and the device interface 3, the logic judgment circuit 4 is first connected to the second output end of the isolation circuit 5 and then connected to the device interface 3 from the second input end of the isolation circuit 5.
[0059] In the connection between the data transmission circuit 6 and the device interface 3, the data transmission circuit 6 is first connected to the isolation circuit 5 and then connected to the device interface 3 from the isolation circuit 5. That is, the components in the enhancement device that need to be connected to the device interface 3 must first be connected to the isolation circuit 5 and then connected to the device interface 3, so that the components inside the enhancement device are isolated by the isolation circuit 5. When the induced current in the secondary arrangement path exceeds the limited current (lightning strike or other faults), the isolation circuit 5 will instantaneously disconnect the data transmission path and power transmission until the fault is eliminated and the current returns to normal before reconnecting.
[0060] As Figure 1 - Figure 2 shown, specifically, when in use, the enhancement device is installed and connected to the secondary arrangement (in this embodiment, the enhancement device is provided with two device interfaces 3). When the secondary arrangement needs to work, a look operation is performed on the server side of the instrument vehicle for two secondary arrangements ( Figure 2Power on the 10 - wire and 20 - wire (in the middle) and check the on - off status. When the device interface 3 near the instrument vehicle in the enhancement device receives a power - on signal, the device interface 3 transmits the power - on signal to the logic judgment circuit 4. After receiving the power - on signal transmitted by the device interface 3, the logic judgment circuit 4 issues an instruction to the self - locking circuit 2, causing the self - locking circuit 2 to disconnect from the device interface 3 that has received the power - on signal until the power - on signal disappears. And at this time, the self - locking circuit 2 is in a connected state with other device interfaces 3 that have not received the power - on signal, realizing the locking of the power supply direction.
[0061] Then the boost circuit 1 boosts the external 12V power supply voltage to 24V and transmits it to the device interface 3 connected to the self - locking circuit 2 through the self - locking circuit 2. Then this device interface 3 supplies power to the acquisition station connected to it. Compared with the 12V power supply station of the source, this enhancement device boosts 12V to 24V, enabling more acquisition stations to be set between this enhancement device and the next power supply station (24V can drive more acquisition stations to work compared to the condition of 12V). In this way, the required number of power supply stations is reduced, solving the problem of insufficient power supply stations. At the same time, this enhancement device is provided with the data transmission circuit 6 to ensure the efficiency of information transmission, ensuring that the overall bandwidth capacity will not be weakened due to the use of this enhancement device.
[0062] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0063] It should also be noted that in this text, terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, relative terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations, nor can they be construed as indicating or implying relative importance. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.

Specific examples are used in this text to elaborate on the principles and implementation manners of the present application. The description of the above embodiments is only for helping to understand the present application, and the content of this specification should not be construed as a limitation to the present application. At the same time, for those of ordinary skill in the art, according to the present application, there will be various forms of changes in the specific implementation manners and application scopes. It is not necessary and impossible to list all the implementation manners here, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
