Description

Technical Field

[0001] Embodiments of the subject matter disclosed herein relate generally to docking stations configured to receive multiple wireless seismic acquisition nodes for testing, recharging, and data downloading, and more particularly to docking stations having docking stations with interchangeable plugs for accommodating different types of wireless seismic acquisition nodes. Background Art

[0002] Land seismic data acquisition and processing generates contours (images) of geophysical structures beneath the earth's surface, known as the subsurface. Although such contours do not provide the exact location of oil and gas reservoirs, such contours indicate the presence or absence of such reservoirs to those trained in the art. Therefore, providing high-resolution images of the geophysical structures beneath the earth's surface is an evolving process.

[0003] Reflection seismology is a geophysical exploration method used to determine the subsurface properties of the Earth, which is particularly useful in the oil and gas industry. Terrestrial reflection seismology is based on the use of a controlled energy source that sends energy into the Earth. By measuring the time it takes for the reflection to return to multiple receivers distributed over the area of ​​interest, the depth of the features that caused this reflection can be assessed. These features may be associated with subsurface hydrocarbon deposits.

[0004] A system for recording reflections of seismic waves from geological structures present in the subsurface utilizes multiple seismic nodes. Seismic nodes can provide good data because they facilitate data acquisition using wide azimuth geometry. Wide azimuth coverage helps image beneath complex overburden formations, such as those associated with salt bodies. Seismic nodes can also provide multi-component data.

[0005] like Figure 1As shown, for a given seismic survey 100, hundreds (if not thousands) of wireless seismic nodes 110 are distributed over an area of ​​interest 120 to record seismic signals. The wireless seismic nodes 110 may be arranged over the area 120 according to a given ordered pattern or in any other manner. The wireless seismic nodes 110 are configured to exchange data between wireless seismic nodes in an ad-hoc network. In one embodiment, the wireless seismic nodes 110 communicate with a general controller 130 and may receive instructions or commands from the controller. In another embodiment, a collector 140 having its own antenna 142 and processing capability 144 may move around each node and collect stored seismic data. Each seismic node 110 includes dedicated electronics housed inside the node and at least one antenna 112 extending outside the housing. The recording of seismic signals may be achieved in various ways, for example, in short time periods repeated over long time periods or continuously over long time periods. Regardless of the method selected for recording seismic data, wireless seismic nodes have a limited amount of electrical power for operation and also have a limited amount of memory for recording seismic data. Electrical power constraints are further exacerbated by the need for nodes to communicate between themselves and / or with acquisition devices that may pass through the area of ​​interest to collect the stored seismic data and / or with one or more servers for various reasons (not of concern to this article). In one embodiment, the wireless seismic node is configured to receive GPS signals to provide timestamps for the recorded data and / or also to obtain the geographic coordinates of the node. All of these actions deplete the limited electrical energy stored by each node, and ultimately the node's battery is depleted and needs to be recharged.

[0006] When the wireless seismic nodes are operating at low power, the wireless seismic nodes require intervention from the operator of the seismic survey. Typically, for this situation, the operator of the seismic survey collects all the seismic nodes and carries the seismic nodes to a maintenance facility to recharge the seismic nodes or the operator drives a vehicle equipped with a power source, connects the power source to each seismic node, and recharges the batteries of the seismic nodes. U.S. Patent No. 7,668,044 discloses a system configured to receive a plurality of identical wireless seismic nodes for battery recharging and data downloading, such as Figure 2 As shown, this figure corresponds to the reference Figure 1 H, the entire contents of which are incorporated herein by reference. System 200 includes a plurality of charging assemblies 193 connected to respective ports 190. Seismic nodes are attached to ports 190 for recharging. The flow of recharging energy can be regulated by power breaker 191. System 200 also includes a power supply 187 for each charging assembly 193. Data flows from charging assembly 193 to host 183. Figure 2Also shown is a data reduction computer 140 which is connected to the host computer 183 and is configured to perform analysis of the received data.

[0007] However, this system has some problems due to the following reasons. Figure 1 D and Figure 1 As shown in FIG. E (not reproduced herein), the handle and antenna of the seismic node need to be removed before placing the seismic node into the recharging system described in the reference. Figure 1 F (not reproduced herein). For thousands of seismic nodes, the operation of removing the antenna and handle of each seismic node is itself a cumbersome and time-consuming process, which is undesirable. In addition, the reference discloses a method for Figure 1 The system shown in F recharges a single type of seismic node. Since some seismic acquisition systems include more than one type of wireless seismic nodes that are constructed with different components and different plugs for connecting to the recharging system, the system proposed by this reference is limited to those seismic acquisition systems that use a single type of seismic node. If another type of seismic node is used, the system in this reference cannot handle the problem.

[0008] Therefore, there is a need for a system that can quickly accommodate multiple seismic nodes without the need to assemble / disassemble any portion of the node. In addition, there is a need for a system that can accommodate different types of seismic nodes. Summary of the invention

[0045] The following embodiments are described with reference to the accompanying drawings. The same reference numerals in different drawings represent the same or similar elements. The following detailed description does not limit the present invention. The scope of the present invention is actually defined by the appended claims. For simplicity, the following embodiments are discussed with respect to a docking station that can be reconfigured to selectively accommodate multiple wireless seismic nodes of two different types, and the docking station is used to test the nodes, recharge the batteries of the nodes, and / or download seismic data of the nodes. However, the embodiments to be discussed next are not limited to docking stations that can be selectively reconfigured to accommodate and process only two types of seismic nodes, but the docking station can be constructed to accommodate and process two different types of seismic nodes at the same time or to accommodate and process other types of seismic nodes in addition to the two types.

[0046] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0047] According to an embodiment, the docking station is integrated with a plurality of docking stations, and a plurality of docking stations can be reconfigured to accommodate different types of seismic nodes. Each docking station has a docking port, which is configured to establish electrical contact with the corresponding autonomous wireless seismic node. The docking port can be quickly removed from the docking station, and another docking port suitable for another seismic node can be attached to the docking station to cooperate with the other seismic node. In one application, each docking port includes two electrical contacts on one side and the same electrical connection portion, the two electrical contacts are used to cooperate with the appropriate seismic node, and the electrical connection portion is used to connect to the docking module of the docking station. The electrical connection portion is configured to slide in and out of the docking module, and the docking port can be attached to the docking module by screws. The docking station has a joint mechanism for mechanically connecting to the seismic node, thereby maintaining the established electrical connection between the docking port of the docking station and the seismic node. The assembly or disassembly of the seismic node is not involved in the docking or disengagement process. In other words, it is not necessary to physically access the interior of the seismic node to recharge the battery and / or download seismic data from the seismic node. The docking station is configured to not only recharge the batteries of the seismic nodes, but also to collect seismic data from the seismic nodes, test the seismic nodes, update the firmware of the seismic nodes, or reconfigure the software of the seismic nodes. The single integrated control unit of the docking station is configured to achieve all of these functions with one docking operation. The details of the docking station will now be discussed with reference to the accompanying drawings.

[0048] Before discussing the details of the new docking station, a brief discussion of the two types of autonomous wireless seismic nodes is deemed appropriate. The autonomous wireless digital field unit (DFU) 300 or digital node in Figure 3 . The seismic node is constructed to communicate (wirelessly) using a transceiver and an antenna, i.e., wirelessly, and also to operate independently of a common control unit of the entire seismic survey, i.e., autonomously. The digital node 300 has a housing 302, a handle 304 (e.g., a rope) attached to the housing 302, and a spike 306 removably attached to the housing 302. The handle 304 is optional and is constructed to provide an operator of the node with a means for carrying the digital node. The spike 306 is constructed to have a sharp tip 306A for penetrating the ground, thereby achieving a good connection between the ground and a seismic sensor (e.g., a MEMS sensor) located within the housing.

[0049] The housing 302 is composed of two parts, a base 310 and a cover 320. The cover 320 is attached to the base 310 so that the housing 302 forms a sealed internal chamber 312 (discussed later). It should be noted that the chamber 312 is formed within the base 310 and has an open side 312'. The cover 320 is configured to close the open side 312' and seal the chamber 312 when attached to the base 310. The cover 320 can be attached to the base 310 in various ways. Figure 3The illustrated embodiment shows that the cover is attached to the base 310 with screws 322. Any type of screws can be used. In this embodiment, four screws are used. However, it will be understood by those skilled in the art that more or fewer screws can be used. It should be noted that, as discussed later, the handle 304 is attached to the base 310, rather than to the cover 320, because the same base is used for other types of sensors. In addition, the nail 306 is attached to the base. In this embodiment, the cover 320 has only one element, namely the external connection plug 330 (which will be discussed in more detail later), and is configured to cooperate with the corresponding docking port of the docking station. The external connection plug 330 has a first pin 332 and a second pin 334 for electrically connecting to the docking port. The first pin 332 and the second pin 334 are surrounded by a protective skirt 336, which is configured to not only absorb impact, but also prevent water from entering the chamber 312. Furthermore, the cover 320 has a rigid band 338 formed around the protective skirt 336 to prevent any accidental impact on the pins 332 and 334 .

[0050] The base 302 is shaped as a box with a groove-type recess 340 formed around three sides of the box. The recess 340 is shaped to conform to a human hand so that an operator of the node can easily operate the node. This feature also implies the size of the base 310 (less than 20 cm) for fitting the operator's hand. In this way, it is easy to operate the node.

[0051] Figure 4A An autonomous wireless simulated field unit (AFU) node 400, or simulated node herein, is shown, which shares the same base 310 as the DFU node 302. Thus, the AFU node 400 has a housing 402 including the base 310 and another cover 420. The handle 304 is the same handle as the handle of the DFU node 302. The base 310 has the same recess 340 for operator convenience. The cover 420 is attached to the base 310 by screws 322 that are the same as the screws of the DFU node 302. However, for reasons that will be discussed later, the external connection plug 430 of the AFU node is different from the external connection plug 330 of the DFU node. Figure 4B The housing 402 is shown having a receiving unit 350 formed in the base 302 and configured to receive the nail 306. The receiving unit 350 may have threads 352 that match corresponding threads on the nail 306 so that the nail 306 can be removed as needed. For the ADU unit 400, no nail is required, so Figure 4A and Figure 4B The housing 402 is shown without the spikes 306. Thus, the spikes 306 may be added or removed relative to the base 310 as desired.

[0052] Figure 5An exploded view of the interior of the housing 302 of the node 300 and the various electronic and non-electronic components stored by the base 310 is shown. With respect to the interior of the base 310, it should be noted that the interior of the base 310 defines a chamber 312 that is open only through one face 312' that is configured to be completely covered by the cover 320 when attached to the base 310. As shown, within the chamber 312, there is a first guide 314 that extends linearly along a first direction X. The first guide 314 can be made of the same material as the base 310 or a different material. In one embodiment, the first guide 314 and the base 310 are both made of plastic or a composite material. However, in another embodiment, the first guide 314 and the base 310 are made of metal.

[0053] The chamber 312 may also include a second guide 316, which may extend parallel to the first guide 313. Both the first guide and the second guide extend along opposite sides (or faces) of the base 310, and the first guide and the second guide are configured to guide various elements into the base. For example, the first guide 314 is configured to guide the main electronic board 510 into the chamber 312, and the second guide 316 is configured to guide the battery pack 530 into the chamber 312. The main electronic board 510 includes a printed circuit board on which one or more electronic devices 512 are added. The electronic device 512 may include an integrated circuit 514 used as a controller, a memory device 515 (e.g., a removable SD card or any other equivalent storage device) configured to store the collected seismic data, a single antenna 516, a transceiver 517, and a GPS module 518. Other electronic devices may be included as necessary. The antenna 516 is connected to a transceiver 517, which is configured to establish wireless communication with a collector device and / or with neighboring nodes and / or with a global control unit, while the GPS module 518 receives GPS signals that may include time stamp and location information. In one application, the digital node 300 includes a single transceiver and a single antenna to communicate with other nodes and with the collector device. As will be discussed later, the processor 514 can coordinate one or more functions of the node 300.

[0054] The entire main electronic board 510 can be connected to a dedicated buffer or damping element 520A and 520B, and the assembly is inserted into the cavity 312 along the first guide 314. Therefore, the damping elements 520A and 520B directly contact the first guide. The damping element is made of a damping material, that is, a material that absorbs the kinetic energy caused by the impact and converts the kinetic energy into other forms of energy (such as heat). Examples of such materials are rubber or soft plastic or composite materials. Each damping element can be implemented as a beam fixed at the end of the damping element, but the rest of the beam is allowed to oscillate to reduce the impact. The purpose of the damping element is to absorb any kinetic energy that may otherwise be transmitted to the main electronic board (for example, if the node falls on the ground) or from the internal vibration caused by the transportation of the node, so that the electronic devices on the main electronic board are not damaged. In this way, there is no hard point contact between the main electronic board and the base. The damping element has a second purpose, which is related to the alignment of the main electronic board with the external connection plug 330, which will be discussed later.

[0055] Figure 6 Only the base 310 and the main electronic board 510 attached to the respective guides and the battery pack 530 within the chamber 312 are shown. It should be noted that the battery pack 530 is much smaller than the batteries previously used for seismic nodes. For example, a typical battery previously used for seismic nodes includes 10 cells, while the battery pack 530 may include only 4 cells. This is because the main electronic board 510 has been optimized to include fewer electronic components and / or low-power processing elements. In addition, the processor 514 is a low-power microcontroller, and the power efficiency of all electronic devices has been improved. In addition, only one transceiver is used to perform the following two items: (1) multi-hop routing with other nodes and (2) local data exchange with the collector device (i.e., long-distance and medium-distance operations), which also requires less energy. The combination of all these factors allows the DFU node 300 or AFU node 400 to use a smaller battery than existing seismic nodes.

[0056] Figure 6 The main electronic board 510 is also shown to have two or more connection strips 522 on one side, so that when the cover 320 is attached to the base 310 , the connection strips 522 will automatically engage with corresponding electrical connectors of the external connection plug 330 . Figure 6 It is also shown that the second guide 316 may include an additional guide 316' configured to support the weight of the battery pack 530. The additional guide 316' provides a rigid bottom tray that is configured to withstand collisions of the node with the ground and also ensure a good connection. The rigidity of the bottom tray can be used to eliminate vibration modes. The additional guide 316' can be configured with the second guide 316 to ensure that the battery pack 530 is clamped or snapped in place without the need for additional fastening devices. Figure 6 It can also be seen in the figure that a hole 610 is formed in one side of the base 310. This hole can be used to attach a rope or line so that the entire node 300 can be easily transported when deployed in the field.

[0057] Back to Figure 5 , the battery pack 530 has its own shock absorbers 532A and 532B attached to the battery pack, and these shock absorbers engage with the second guide 316, as shown. Figure 6 As shown, the battery pack is fixed to the inside of the base 310. The shock absorbers 532A and 532B not only protect the battery 530 from various unexpected impacts (e.g., the node falls to the ground) and internal vibrations caused during transportation, but also allow the size of the battery pack to expand due to the charging / discharging process and / or temperature. Figure 5 and Figure 6 Both show electrical connections 534 that electrically connect the battery pack 530 to the main electronic board 510 for power supply. Figure 5 and Figure 6 In the illustrated embodiment, electrical connections 534 are fixedly attached to the battery pack 530 and removably connected to the main electronics board 510 via connectors 536. It should be noted that by placing the battery pack 530 on the bottom of the base 310, the center of gravity of the entire node is lowered due to the second guide 316 being located below the first guide 314, which is desirable because it makes the node more stable and less prone to falling toward the ground when the spikes 306 are not fully embedded in the ground.

[0058] Figure 5 Also shown is a sensor device 540 which is configured to be attached to the base 310 via screws 542 . Figure 6A sensor device 540 is shown attached directly to the wall of the base 310. This is because the sensor 544 attached to the plate 546 of the sensor device 540 needs to detect any parameter related to the particle motion to record the parameter. It should be noted that in this embodiment, the plate 546 includes an analog-to-digital converter for converting the analog signal recorded by the sensor 544 into a digital signal. Therefore, the signal sent to the main electronic board 510 by the sensor device 540 is a digital signal. For this reason, the sensor device 540 is also referred to as a digital sensor device here. The particles of the ground where the nail 306 is placed vibrate due to the generated seismic waves. The vibration of these particles is transmitted to the sensor device 540 through the nail and the base. In order to record these particle vibrations, a good connection between the sensor 544 and the base 310 is necessary. The sensor 544 is configured to detect at least one of the displacement, velocity or acceleration of the particle. In one embodiment, the sensor 544 is a micro-electromechanical system (MEMS) as follows, which is configured to determine the acceleration along a single axis or three mutually perpendicular axes. Any other type of sensor can be used to determine the parameters related to particle vibration. Also like Figure 6 As shown, the sensor device 540 is electrically connected to the main electronic board 510 via an electrical connection 550. In this embodiment, the electrical connection 550 is fixedly attached to the main electronic board and removably attached to the sensor device. Therefore, when the assembly is modified to form an AFU unit as described later, the sensor device 540 is removed and the electrical connection 550 is not attached to any component. In one embodiment, if the electrical connection 550 is made to be removably attached to the main electronic board, the electrical connection can also be removed for use in the AFU unit.

[0059] Figure 5 Also shown is a seal 560 placed between the cover 320 and the base 310 for sealing the chamber 312. Figure 5 The node 300 is shown to optionally include a desiccant material 570 attached to the cover 310 and a radio frequency identification (RFID) tag 572 also attached to the cover 310. The desiccant material 570 is used to absorb moisture from inside the chamber 312, while the RFID tag 572 provides a unique ID for the node, making it easy to identify which node is placed where. It should be noted that during a land seismic survey, hundreds if not thousands of nodes (or even tens or hundreds of thousands of nodes) may be placed over the area of ​​interest, and tracking all of these nodes is a considerable task. By having each node tagged with an RFID having a unique ID, the task of identifying the node is made easier.

[0060] Figure 5It is also shown that the nail 306 can be used with the sealing ring 307 to attach to the outside of the base 310. To prevent the nail 306 from being separated from the base 310, the nail 306 can be fixed to the receiving unit 350 (see Figure 3 ).in addition, Figure 5 and Figure 6 It is shown that a soft molded protective cover 311 can be provided on a portion of the base 310 to further prevent any undesirable kinetic energy caused by a fall from being transmitted to the node, thereby protecting the electronic device. Figure 6 As shown, the ends of the soft molded protective cover 311 may be over molded to further enhance the protection.

[0061] As will be discussed later, Figure 5 It is also shown that the cover 320 may have notches or slots 324 formed on opposing sides so that the node can be attached from a docking station to a docking station and remain in place for recharging the battery and transferring data.

[0062] As discussed previously, the base 310 may be used not only for the DFU node 300 but also for Figure 4A and Figure 4B In other words, the same base 310 can be used for different types of nodes, that is, the bases are interchangeable for these nodes. Figure 7 As shown, the base 310 has the same construction as the base 310 of the DFU node 300. Even, the electronic components placed in the base 310 are almost similar to the electronic components of the DFU node 300. More specifically, Figure 7 The same main electronic board 510 and battery pack 530 are shown inserted, along with their shock absorbers, into guides formed in the base. For the AFU node, there is no sensor device 540, since a different sensor is attached to the node. Therefore, the sensor device 540 and the electrical connection 550 of the sensor device 540 are omitted in the AFU node 400. In one embodiment, in addition to the cover 320, the sensor device 540 and the electrical connection 550, Figure 5 All other components shown are present in Figure 7 Therefore, all these common components will not be discussed again here.

[0063] The cover 420 is different from the cover 320 of the DFU unit 300 in its external connection plug 330. The cover 420 has a different external connection plug 430 that is configured to be attached to one or more external sensors (not shown), such as a seismic detector, via a thread 432. The external connection plug 430 is Figure 8 4 and includes a pin 810 disposed in a hole 812 formed in a half body portion 814 of the connection plug 430. The half body portion 814 of the connection plug only occupies half of the connection plug. The other half is a recess 816 from which a tubular member 818 rises to the same level as the half body portion 814. A hole 820 with a tubular metal contact 822 is formed inside the tubular member 818 to receive a pin from an external sensor (discussed later).

[0064] exist Fig.9A and Fig. 9B 4 shows a connection mechanism 900 that mates with the connection plug 430. In one application, the connection mechanism 900 is attached to an external sensor. Fig.9A A connection mechanism 900 is shown having a metal pin 902 and a metal tubular member 904 configured to mate with the tubular metal contact 822 and the pin 810, respectively. The body 906 of the connection mechanism 900 is configured with a raised half portion and a recessed half portion to mate with the corresponding recessed half body portion 916 and raised half body portion 914 of the connection plug 430, respectively. A sleeve 910 is attached to the connection mechanism 900 and configured to threadably engage with corresponding threads 432 formed on the outer surface of the connection plug 430. Fig. 9B A connection mechanism 900 is shown which also has a cable 920 that transmits information and / or power from the pin / tubular member to a sensor 930 attached to the cable. In this regard, Fig. 9B A connection mechanism 900 and a sensor 930 (eg, a geophone) are shown, the sensor 930 being attached to a cable 920 of the connection mechanism 900. Although Fig. 9B Only a single sensor 930 is shown attached to the cable 920, but there may be multiple sensors attached to the cable. In another embodiment, an external sensor(s) 930 may be attached to the connection plug 430 by a connection mechanism similar to the connection mechanism 900 but without the sleeve 910. The external sensor 930 records the analog data that is thus transmitted to the main electronics board 510. For this reason, the seismic node 400 is an analog field unit. Those skilled in the art will appreciate that, although Fig.9A and Fig. 9B A KCK2 type connector is described, but other connectors may be used as long as the connection mechanism and the connection plug on the cover of the node are constructed to mate with each other. The choice of a KCK2 type connector in these figures is reasonable because conventional sensors 930 in the industry already have this type of connection, and therefore, it is expected that the new node 400 will be backward compatible with existing sensors. However, this historical reason does not prevent other types of connections from being used for the AFU node 400.

[0065] Based on the above description of the DFU node 300 and the AFU node 400, it should be noted that regardless of the type of sensor that needs to be deployed for land seismic surveying, the same base 310 is used. The unique and common base 310 of these different types of seismic nodes is used by being able to connect and process different types of seismic nodes. Fig.10 The docking station 1000 (also referred to as a docking stand) shown in FIG. Fig.10 The docking station 1000 shown in the exploded view includes a frame 1010, which is configured to hold all other components. The frame 1010 can be formed as a cabinet that can stand on the floor. For safety, the frame can be attached to the wall by screws (not shown). In one embodiment, the frame 1010 has one or more hooks 1012 so that the frame 1010 can be transported to the desired location with a crane. The frame can be made of plastic, composite material or metal.

[0066] Fig.10 It is also shown that the docking station 1000 includes a network connection device 1020, which can include various electronic devices for connecting the docking station to the Internet or a private or public communication network. For example, in one embodiment, the network connection device 1020 includes an Ethernet switch for connecting to the Internet. In another embodiment, the network connection device 1020 may include a router, a satellite communication device, a base station connected to a wireless telephone network, or any other device for connecting to a communication network. If the privacy of the data is concerned, the network connection device 1020 may include an encoding mechanism (software and / or hardware) for encoding the data. The network connection device 1020 can also be configured to connect only to a private network operated by the operator of the docking station 1000. In one embodiment, the network connection device 1020 is connected to a server 1090. It should be noted that the server 1090 can be located in the docking station, near the docking station, or away from the docking station.

[0067] Internally, the network connection device 1020 is connected to a collector-charger module (HCM) 1030, which serves as the brain of the docking station 1000, and for this reason, the collector-charger module is also referred to as a control module. The internal structure of the HCM module 1030 will be discussed in more detail later. In one embodiment, the HCM module 1030 is configured to slide into the frame 1010 along a dedicated track 1032. In another embodiment, the HCM module 1030 is attached to the frame 1010 by screws. In another embodiment, the HCM module 1030 is configured to slide along the track 1032 and then connected to the frame 1010 by screws.

[0068] Fig.11AThe front of the HCM module 1030 is shown with a plurality of ports and indicators, in which an on and off switch 1110 for the module is provided, a corresponding LED indicator 1110A that is illuminated when the HCM is powered and is dark when the HCM is not powered, a docking station universal power switch 1112 configured to cut off power to all elements of the docking station 1000, another LED indicator 1114 configured to display the status of the HCM module (i.e., whether there are any problems with the module), a video port 1115 for providing, for example, a video signal associated with the docking station, a power port 1116 for a monitor discussed later, a fast communication port 1118 for connecting to a monitor, and a USB port 1119 for servicing the HCM module. It will be appreciated by those skilled in the art that more or fewer ports and indicators may be added to the HCM module or that the ports may be redistributed on another face of the module.

[0069] Fig. 11B The back side 1100B of the HCM module 1030 is shown, and this side also holds a plurality of ports. For example, the back side includes a power input port 1120 that receives external power. This power is then transmitted to a power output port 1122 so that power is supplied to other elements of the docking station 1000. Fig.11A The power switch 1112 shown in FIG. 1 is configured to turn on and off the electrical connection between the port 1120 and the port 1122. Fig. 11B As shown, the back side 1100B may also include a first network port 1130 and a second network port 1132, the first network port 1130 being used to connect to the network connection device 1020, and the second network port 1132 may also be connected to the network connection device 1020 or to other elements of the docking station 1000. The back side may also have a power output port 1134 for service, for example, a 12V output connector for service power, and optionally a fuse 1136 for the power output port 1134.

[0070] Fig. 11C 1030. Some of these components include a PC card 1140, which includes at least a processor 1142 and a memory 1144. In one embodiment, the PC card 1140 may be a computer board. The processor 1142 is configured to control charging and data collection / transfer of the various nodes 300 and / or 400. In addition, the processor 1142 may be configured to update the firmware of the node and / or test the node. Fig.10 As shown, the memory 1144 may be configured to store various commands and instructions for updating nodes, testing nodes, charging batteries of nodes, and controlling data transfer from nodes to the server 1090 .

[0071] To achieve these capabilities, a power transformer 1150 is provided within the HCM module 1030 and generates a low voltage (e.g., 12V) that is used to feed the electronics within the HCM module 1030 and also to feed the electronics of each docking module 1050. Those skilled in the art will appreciate that any other voltage may be generated. The low voltage from the power transformer 1150 is fed to the electronics of each docking module 1050. In one application, such as Fig.11D As shown, power cables or wires 1152 extend from the HCM module 1030 to a central power strip 1154, and each docking module 1050 can be connected to the power strip 1154 with a corresponding power cable 1051 to receive the voltage of the power strip (e.g., 220V, but other values ​​are also possible). Fig.11D It is also shown that the HCM module 1030 is connected to the network connection device 1020 via two network cables 1138 (fewer or more cables, such as Ethernet cables, may be used), while each docking module 1050 is connected to the same network connection device 1020 via a corresponding network cable 1053 (e.g., Ethernet cables). In this way, a network is established between the HCM module and the docking module, and data and / or commands can be exchanged between these elements.

[0072] With these networks and electrical connections between the various docking modules 1050 and between the docking modules and the HCM module 1030, data transmitted from each docking module to the HCM module can be encoded so that the data source at the HCM module 1030 (i.e., which node and docking module each portion of the data originated from) is known. Fig.11E The coding scheme discussed above allows all docking modules 1050 to have the same electrical configuration, i.e., each of the six docking modules 1050 is identical. To avoid having to configure the docking station 1000 any time a docking module 1050 is added or removed (or in the case of maintenance), a specific cable 1160 (e.g. Fig.11D As shown) connects the power port 1134 of the HCM module 1030 to each corresponding power port 1055 of the docking module 1050.

[0073] Fig.11EA portion of the electrical configuration of the docking station 1000, various electrical connections between the HCM module 1000 and the docking module 1050, and some of the internal electrical connections of the docking module 1050 are shown. It should be noted that each docking module 1050 has a 16-pin electronic board 1057. The electronic board 1057 may also include a processor 1052 and a memory 1054. Other components may be present on the electronic board 1057. In this embodiment, the power cable 1160 extending from the HCM module 1030 to each docking module 1050 has a ground line 1160A connected to pin 7 of the electronic board 1057 of the first docking module 1050-1, and also has a signal line 1160B connected to pin 16. Fig.11E 1050-2, and pin 16 is internally connected to pin 8. In addition, the figure also shows that pin 7 is connected to pin 15 of the second docking module 1050-2 through ground line 1160A, and pin 8 is electrically connected to pin 16 of the second docking module 1050-2 through signal line 1160B. These power connections are then repeated for subsequent docking modules 1050-3 to 1050-6.

[0074] Fig.11E Also shown is a shunt conductor 1056 that connects pin 6 to pin 14 of the first docking module, pin 5 to pin 13 of the second docking module, and so on. The shunt conductor 1056 implements a unique pin connection for each docking module. This unique connection is read by the processor 1052 of each docking module and converted into a level (LEVEL) code that identifies the level of the corresponding docking module in the docking station, where the top docking module 1050-1 is LEVEL=1 and the bottom-most docking module 1050-6 is LEVEL=6. Names and / or other values ​​can be used for this parameter, as long as the position of the docking module in the docking station is identified.

[0075] In addition, each docking module 1050 has a processor connected to six docking stations, and the processor 1052 is configured to identify each of the six docking stations, and the docking station is encoded with a parameter location (LOCATION) with a value of 1 to 6. Other names and other values ​​of this parameter can be used. When the seismic data from each node 300 is downloaded to the docking module 1050, the processor 1052 in each docking module is configured to generate a value of the LEVEL parameter and a value of the LOCATION parameter, so that each batch of seismic data downloaded from the node is marked with the value of the LEVEL and LOCATION parameters. Then, the seismic data is transmitted to the HCM module together with these values ​​by each docking module, for example, along the network cable 1053 and the network connection device 1020.

[0076] Back to Fig.10, the docking station 1000 also includes a screen or monitor 1040 attached to the frame 1010. The screen 1040 can be a touch screen. The screen 1040 is connected to the power port 1116 of the HCM module 1030 by a cable and is connected to the port 1118 by a communication cable to send commands to the processor 1142 located in the module 1030. For example, the screen 1040 can be a touch screen, allowing the operator of the docking station to view all nodes connected to the docking station, the battery level of the docking station, the amount of seismic data that has been transferred from the node to the docking station, the status of the node, the firmware version of the node, and any other information related to the node. The operator can use the touch screen 1040 to update the firmware of a given node or node group. The operator can also use the touch screen to reconstruct the software of a given node or node group. In one application, the operator can use commands directly input by the touch screen to run various tests on a given node or node group. The operator can stop or start the seismic data transfer from the node to the server 1090 associated with the docking station 1000 at any time through the touch screen 1040. In another application, screen 1040 is configured to provide an operator with a visual indication / signal regarding the status of a node or group of nodes. For example, the screen may display all nodes that are currently charging in red and all nodes that are fully charged in green. Many other indications and various parameters associated with the nodes may be displayed by screen 1040.

[0077] The docking station 1000 also includes a plurality of docking modules 1050 . Fig.10 Six different docking modules 1050 are shown. However, depending on the application, the docking station can be configured with more or fewer docking modules. Reference numeral 1050 is used herein to indicate a universal docking module, while reference numeral 1050-1 is used to indicate a specific docking module. In this embodiment, the docking modules are connected to the frame 1010 by screws. However, the docking modules can be attached to the frame by other means such as clips, or the docking modules can slide into a dedicated track.

[0078] Each docking module 1050 has the same configuration and is capable of receiving: (1) only DFU nodes, (2) only AFU nodes, or (3) a mix of DFU and AFU nodes. The same docking module 1050 can be reconfigured to accept one of the node configurations (1) through (3). Fig.10 Each docking module 1050 is shown with 6 docking stations 1060, but the docking modules can be sized to have fewer or more docking stations. Reference numeral 1060 is used herein to refer to the docking stations as a whole. When referring to a specific docking station, reference numerals 1060-1, 1060-2, etc. will be used.

[0079] Fig. 12AThe docking station 1000 is shown as being configured with an analog port 1080 for receiving an AFU node 400, and Fig. 12B A docking station is shown configured with a digital port 1070 for receiving a DFU node 300. Not shown is a configuration where the same docking station is configured to receive both a DFU and an AFU node. It should be noted that the same docking station is used for both configurations except that different ports of the docking station are used to accommodate one node or the other. In addition, Fig. 12A and Fig. 12B Each of the indicators 1210 is shown to be fixed to the frame 1010, indicating the docking module in a visible manner, and is independent of the docking module. In one embodiment, the indicator 1210 is a physical label. In another embodiment, the indicator 1210 is an LCD display controlled by the HCM module 1030, and the displayed value can be modified / changed by the operator of the HCM module as needed.

[0080] The docking module 1050 may be configured as follows: Fig.13A The receiving DFU node 300 is shown, or Fig. 13B The receiving AFU node 400 is shown, or Fig. 13C The shown accommodates a mix of DFU and AFU nodes. Fig.13A The first configuration of the docking module 1050 shown is referred to herein as a digital configuration and utilizes a digital port 1070 ( Fig.13A Only two docking stations are marked, but all docking stations have the same construction). Fig. 13B The second configuration of the docking module 1050 shown is referred to herein as an analog configuration and uses the analog ports 1080 ( Fig. 13B Only two docking stations are marked, but all docking stations have the same construction). Fig. 13C The third configuration of the docking module 1050 shown is referred to herein as a hybrid configuration and uses a digital port 1070 for the docking station 1060-2 and an analog port 1080 for the docking station 1060-5. Fig. 13C Only two docking stations are labeled, but a first subset of all docking stations may have digital ports and a second subset of all docking stations may have analog ports, where the first and second subsets may be equal to or less than the entire set of docking stations for a given docking module.

[0081] FIG. 13A to FIG. 13CEach of the figures also shows that each docking station includes a receiving portion 1062, which is configured to receive the cover 320 or 420 of the DFU or AFU node. The cross-sectional shape of the receiving portion 1062 is exactly the same as the shape of the cover 320 or 420. The receiving portion 1062 can be made of plastic or rubber or a composite material, and can have a certain depth so that the entire cover of the DFU node and the AFU node fits within the receiving portion. In addition, the figures show that each receiving portion 1062 has a pair of protrusions 1064 (only one protrusion is visible in the figures) formed on the opposite walls of the receiving portion to mate with the recess 324 (see Figure 5 ) are joined so that a good and stable mechanical connection is achieved between each node and the corresponding docking station of each node.

[0082] Fig.14A The docking station 1060 and its receiving portion 1062 having a pair of protrusions 1064 are shown in greater detail. Fig.14A Also shown is a digital port 1070 having a first electrical tubular member 1072 and a second electrical tubular member 1074 configured to mechanically and electrically engage with the first pin 332 and the second pin 334 of the cover 320 of the DFU node 300. In addition, in this embodiment, Fig.14A The digital port 1070 is shown attached to the housing 1062 by three screws 1076. Those skilled in the art will appreciate that more or fewer screws, or even other means of securing the digital port to the housing, may be used within the scope of the present invention. Fig. 14B The digital node 300 is shown attached to the housing 1062. It should be noted that in one embodiment, the cover 320 of the node may be completely within the housing such that only the base 310 is visible. Fig. 14C Pad 1064 is shown removed from receptacle 1062. Two pads 1064 may be attached to beam 1410 by side beams 1412. Side beams 1412 are made of a resilient material so that pads 1064 may move slightly toward and away from the cover of the node as the node enters or leaves the receptacle.

[0083] Fig.15 A docking station 1050 is shown having a housing 1510 configured to receive six docking stations 1060 . Fig.15 Also shown are the digital port 1070 and the analog port 1080 removed from the respective receiving portions 1062. As discussed previously, the digital port and the analog port are interchangeably attached to the receiving portions. The digital port and the analog port are configured to slide into corresponding recesses 1061 formed in the receiving portion 1062 of each docking station 1060. Fig.15The outer shape of the digital port and the analog port is shown to be the same so that the digital port and the analog port fit into the same recess 1061 in the docking station 1060. In this embodiment, the cross-section of the outer shape of the digital port and the analog port is triangular. However, the cross-sectional shape of these ports can also be rectangular, square, diamond or any other shape. In one embodiment, the color of the digital port is different from the color of the analog port so that the operator of the docking station can recognize at a glance what type of port is being used. In addition, when the ports need to be swapped, by having the analog port and the digital port have different colors, the operator of the docking station is prevented from installing the wrong port.

[0084] exist Fig.16 1000 , and includes a digital port 1070 (and / or an analog port 1080), a housing 1510, and a docking station 1060. Although the docking station 1060 is configured to fit into a corresponding slot 1012 in the housing 1510, the docking station is mechanically attached to the plate 1610, for example, by screws. The docking module 1050 also includes electrical components 1620. Among the electrical components 1620, there is a power transformer 1622, which is configured to step down the input voltage (220 or 110V) to a given low voltage (e.g., 5V), which is distributed to each docking station for recharging the respective nodes. In this regard, it should be noted that each docking module 1050 can have a power port attached to the back of the support housing 1640, which is configured to be connected to an electrical outlet present in the docking station 1000. For example, the power output port 1122 of the HCM module 1030 can be connected to a power strip located in the frame 1010 of the docking station 1000, and the power strip can include multiple electrical sockets, one for each docking module. The low voltage end of the power transformer 1622 is connected to each of the digital port or analog port of the docking station for the module through the electrical contacts discussed later. The docking module 1050 can also include a printed circuit board 1630, which includes at least a processor 1632, and the functions of the processor 1632 include, but are not limited to, monitoring the status of each node, the battery power of the node, coordinating the seismic data transfer from the node to the server, updating the software application of the node, and testing the node. The processor 1632 is a local processor. The processor 1632 (in one embodiment, there are more processors in each docking module) can cooperate with the global processor 1142 of the HCM module 1030 to achieve all these functions.

[0085] All of these electronic components are placed in a housing bracket 1640, which can be a metal box with a lip 1642 having one or more holes that allow the entire docking module to be attached to the frame 1010 of the docking station 1000 by screws. In one embodiment, the housing bracket 1640 is configured to mate with the housing 1510 so that one side of each of these elements engages each other using a clamp-like system 1644, while the opposite sides of the two elements can be engaged by screws or equivalent means. A power port 1646 can be secured to the back of the housing bracket 1640 to be connected to the housing 1510 through the above description of the power port. Fig.11D The discussed cable 1051 receives voltage (e.g., 12V as discussed above with respect to the HCM module) from a power strip 1154 located within the docking station. A communication port 1648 (e.g., an Ethernet port or any other port that allows data communication) may also be attached to the back of the housing bracket 1640 and is connected to the housing bracket 1640 by a power cord 1154 disposed within the docking station. Fig.11D The cable 1053 discussed in the above is connected to the network connection device 1020 to obtain access to the Internet or an internal network for transferring seismic data from the node to the server. In one embodiment, the server can be located anywhere, away from or close to the docking station. In one application, the server can be located inside the docking station. Regardless of where the server is located, the server is connected to the network connection device 1020 directly or through a private network or through the Internet to receive seismic data from each node.

[0086] Regarding the digital port 1070 and the analog port 1080, Fig.17A and Fig. 17B They are shown in an exploded view in FIG. Fig.17A The digital port 1070 is shown to include a body 1710 having a triangular cross-section. As discussed above, the body 1710 may have other shapes as long as the recess 1061 formed in the receiving portion 1062 of the docking station 1060 has the same cross-sectional shape. Fig.14A As shown, the body 1710 has three holes 1712 configured to receive corresponding screws 1076. As discussed above, the body 1710 may have only two or more than three holes depending on the shape of the body. The body 1710 has an inner lip 1714 formed in the central portion, the inner lip 1714 configured to protect the first tubular pin 1072 and the second tubular pin 1074. In one embodiment, the first tubular pin and the second tubular pin are identical.

[0087] The first and second tubular pins 1072, 1074 may be configured to have threads 1076 at one end, the threads 1076 being configured to engage with corresponding washers 1716 and nuts 1718 to secure the tubular pins to the body 1710. The electrical connection portion 1720 may have two wires 1722, which are configured to enter the ends of the tubular pins 1072 and 1074 and be crimped therein to achieve electrical connection. The electrical connection portion 1720 is configured to have a header 1724, which, for example, is connected to the printed circuit board 1630 (see FIG. 1 ) of the docking module 1050. Fig.16 ) connection. In fact, Fig.16 The digital port 1070 and its rear electrical connection 1720 are shown. The rear electrical connection 1720 is configured to be wirelessly attached to the printed circuit board 1630. The use of the term "wireless" in this paragraph means that no manual connection is required between the header 1724 and the printed circuit board 1630, as the header 1724 is configured to simply slide onto receiving contacts on the printed circuit board 1630 to make an electrical connection. In this regard, Figure 5 and Figure 7 The connection between the rear pins of the cover 320 or 430 and the band 522 is also wirelessly achieved, i.e., no manual connection is required between these elements to achieve electrical connection. With this wireless connection, after the screws of the digital port 1070 are removed, the digital port 1070 can be simply removed from the corresponding receiving portion, and the analog port 1080 can be inserted into the appropriate position.

[0088] Emulate port 1080 in Fig. 17B 1070. The cross-section of body 1730 is the same as that of body 1710, since both bodies must fit into the same recess 1061 in receptacle 1062. However, body 1730 has a half 1734 in place of lip 1714 that occupies approximately half of a recess 1736 formed in body 1730. The other half of recess 1736 is empty. This configuration of analog port 1080 corresponds to Fig.9A 17. In this regard, it should be noted that pin 902 of connecting mechanism 900 will fit into tubular pin 1738 of electrical portion 1740, which is fitted into body 1730. In addition to having tubular pin 1738, electrical portion 1740 also has pin 1742, which fits into tubular member 904 of connecting mechanism 900. It should be noted that the construction of connecting mechanism 900 is also used for Figure 4A The cover 420 is connected to the external connector 430, except the sleeve 910. Fig. 17B, tubular pin 1738 and pin 1742 are attached to a retaining portion 1744, which is made of plastic, for example, and is configured to keep these elements separated from each other. Tubular pin 1738 and pin 1742 extend through the entire retaining portion 1744 and have corresponding rear pins 1738A and 1742A, respectively. Rear pins 1738A and 1742A can be connected to transition element 1746 and also connected to wire 1722 of electrical connection portion 1720. Rear pins 1738A and 1742A, transition element 1746 and wire 1722 can be crimped together to achieve good mechanical and electrical connection. Because digital port 1070 and analog port 1080 share the same electrical connection portion 1720, digital port 1070 and analog port 1080 can be easily interchanged and placed in storage portion 1062.

[0089] Fig.18 An operational docking station 1000 having multiple docking modules 1050 disposed in the same frame 1010 is shown. A touch screen 1040 is attached to the top of the frame 1010 so that the operator of the docking station can easily monitor the various modules. In one application, the touch screen 1040 displays all docking modules 1050, but also displays all docking stations 1060 so that the status of each node 300 and / or 400 is known. In addition, the docking stations 1060 are distributed in the docking modules 1050 so that the DFU node 300 can be placed into the corresponding docking station 1060 together with the pins 306 of the DFU node 300, that is, the pins 306 do not have to be removed before attaching the node to the docking station. Fig.18 The pegs 306 are shown extending between two docking stations located below the current docking stations. This means that the base 310 is configured with a receiving unit 350 having an attachment peg 306 that is offset from the cover 320 or 420 by a distance sufficient to allow the receiving unit 350 to remain outside of the receiving portion 1062 of the docking station 1060. This new feature speeds up the process of placing a node into a docking module, saving time.

[0090] Reference now Fig.19 Methods for recharging seismic nodes and / or transferring seismic data from nodes to a server are discussed. In step 1900, a group of autonomous wireless seismic nodes is retrieved from the field after a seismic survey has been performed. In step 1902, the group of seismic nodes is divided into a first subgroup 300 of digital seismic nodes and a second subgroup 400 of analog seismic nodes. In one application, the first subgroup is empty and the second subgroup is equal to the group. In another application, the second subgroup is empty and the first subgroup is equal to the group. In another application, both the first subgroup and the second subgroup are non-zero.

[0091] In step 1904, the first subgroup of the digital seismic node is placed in the corresponding docking module, and the subgroup of the simulated seismic node is placed in the other corresponding docking modules of the docking station. The digital seismic node and the simulated seismic node share the same base. The digital seismic node has a nail attached to the base, while the simulated seismic node does not have such a nail. The nail is located outside the docking station of the docking module, and the digital seismic node is placed in the docking station of the digital seismic node. In step 1906, the processor of the HCM module determines the power level of the battery of each node and starts charging the battery. In step 1908, the seismic data stored in the seismic node is transferred from each node to the server through the HCM module. In step 1910, the processor of the HCM module runs one or more software instructions for the seismic node. The software instructions may include test related instructions, or update instructions, or other instructions applied to the seismic node and known in the art. In step 1912, the processor of the HCM module collects various information from the docked seismic node, and displays the docked seismic node and related information on a monitor attached to the docking station. At step 1914, the operator may interact directly with the monitor as a touch screen and initiate one or more software commands.

[0092] At step 1916, one type of node is removed from the docking station, and the docking station of these nodes can be reconfigured to receive another type of node. This step includes removing the first type of connection port from the docking station and placing the second type of connection port into the docking station. No other preparatory steps are required to convert the docking module from receiving one type of node to receiving another type of node.
