Description

Technical Field

[0001] This application relates to the field of electromagnetic signal acquisition technology, and in particular to a multi-angle, multi-directional sensor integrated data acquisition device. Background Technology

[0002] Natural electromagnetic pulse signals are radio waves generated by natural objects or phenomena. By collecting and analyzing these natural electromagnetic pulse signals, we can obtain information about the geological conditions of certain areas, which is of great help to geological exploration.

[0003] Because natural electromagnetic pulse signals have strong directionality during propagation, the sensors in the acquisition device are usually required to be directly facing the signal source to improve signal quality. However, achieving perfect alignment is very difficult. In actual operation, it is often necessary to constantly adjust the orientation of the sensor and judge the accuracy of the direction by the intensity of the acquired signal, which results in very low acquisition efficiency. Utility Model Content

[0004] This application provides a multi-angle, multi-directional sensor integrated data acquisition device to solve the problem of low acquisition efficiency caused by adjusting the direction of the sensor in the prior art.

[0005] This application provides a multi-angle, multi-directional sensor integrated data acquisition device, including:

[0006] The box-shaped structure is a hollow cube without a top.

[0007] The partition is located inside the box near the bottom.

[0008] There are multiple mounting plates, which are connected end to end by hinges. The mounting plates located at the edges are also connected to the inner top of the box by hinges.

[0009] Multiple sensors are mounted on a mounting plate.

[0010] The bottom end of the strut is set on the top surface of the partition, and the top end is connected to a mounting plate or a hinge between two adjacent mounting plates. The strut is a telescopic structure. When the strut is extended, the mounting plate rotates to the outside of the box and multiple mounting plates form a curved structure. When the strut is shortened, the mounting plate rotates to the inside of the box.

[0011] The processing board is located between the partition and the inner bottom surface of the box. The processing board is equipped with a processing unit and a storage unit. The processing unit and the storage unit are connected. The processing unit is also connected to the sensor. After the processing unit acquires the natural electromagnetic pulse signal collected by the sensor, it stores it in the storage unit.

[0012] In one possible implementation, each mounting plate is an arc-shaped structure, and multiple mounting plates rotate to the outside of the housing to form a semi-cylindrical structure.

[0013] In one possible implementation, each hinge is equipped with a torsion spring, which is compressed when the mounting plate rotates inward or outward. Once the mounting plate has rotated inward or outward to its designated position, the spring force keeps the connection between two adjacent mounting plates smooth.

[0014] In one possible implementation, each mounting plate is also provided with a side plate at its edge, the side plate being close to the inner side of the housing, and the side plates connecting two adjacent mounting plates being located in different vertical planes.

[0015] In one possible implementation, the side panel has dust-proof brushes on its surface near the inner side of the housing.

[0016] In one possible implementation, the enclosure has an air inlet and an air outlet on opposite sides, and an air inlet pipe and an air outlet pipe on the inner side of the enclosure at positions corresponding to the air inlet and air outlet, respectively, with a cooling fan installed in the air inlet pipe or air outlet pipe.

[0017] In one possible implementation, the air inlet and air outlet are respectively located on the two sides where the enclosure connects to the mounting plate. Both the air inlet pipe and the air outlet pipe are arc-shaped plates, and both the air inlet pipe and the air outlet pipe face the mounting plate. The airflow generated by the cooling fan enters through the air inlet pipe, passes through the mounting plate, and finally flows out through the air outlet pipe.

[0018] In one possible implementation, dust screens are installed on both the air inlet and outlet.

[0019] In one possible implementation, a signal conditioning board is also provided between the partition and the inner bottom surface of the enclosure. The signal conditioning board is connected between the sensor and the processing unit. The signal conditioning board has a conditioning circuit for amplifying, filtering and analog-to-digital conversion of the natural electromagnetic pulse signal.

[0020] In one possible implementation, the top of the housing is provided with a flange, and the device also includes a top cover that is inserted into the outside of the flange when the mounting plate is rotated into the housing.

[0021] The multi-angle, multi-directional sensor integrated data acquisition device disclosed in this application has the following advantages:

[0022] Multiple sensors with different angles are mounted on an arc-shaped mounting plate. This eliminates the need to adjust the orientation of the sensors to accurately face the signal source when collecting natural electromagnetic pulse signals. Only a rough adjustment of the angle of the acquisition device is required, ensuring that at least one sensor is accurately facing the signal source. This saves time that would otherwise be wasted on adjusting the sensor angles. Furthermore, the mounting plate is a movable structure that flips outward to form an arc shape when in use and flips back into the housing when not in use, effectively reducing the size of the device.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Figure 1-3 This is a schematic diagram of a multi-angle, multi-azimuth sensor integrated data acquisition device provided in an embodiment of this application. This embodiment of the application provides a multi-angle, multi-azimuth sensor integrated data acquisition device, including:

[0030] The box 100 is a hollow cube structure without a top.

[0031] The partition 110 is located inside the housing 100 near the bottom surface;

[0032] There are multiple mounting plates 300, and the multiple mounting plates 300 are connected end to end by hinges 302. The mounting plates 300 located at the edge are also connected to the inner top of the box 100 by hinges 302.

[0033] Multiple sensors 310 are mounted on the mounting plate 300.

[0034] The bottom end of the support rod 107 is set on the top surface of the partition 110, and the top end is connected to a mounting plate 300 or a hinge 302 between two adjacent mounting plates 300. The support rod 107 is a telescopic structure. When the support rod 107 is extended, the mounting plate 300 rotates to the outside of the box 100. Multiple mounting plates 300 form a curved structure. When the support rod 107 is shortened, the mounting plate 300 rotates to the inside of the box 100.

[0035] The processing plate 112 is disposed between the partition 110 and the inner bottom surface of the housing 100. The processing plate 112 is provided with a processing unit and a storage unit. The processing unit and the storage unit are connected. The processing unit is also connected to the sensor 310. After the processing unit acquires the natural electromagnetic pulse signal collected by the sensor 310, it stores it in the storage unit.

[0036] For example, the partition 110 may be parallel to the inner bottom surface of the housing 100, forming a cubic space between it and the inner bottom surface of the housing 100 for accommodating the processing plate 112. It should be understood that the bottom plate of the housing 100 needs to have an openable structure to facilitate the installation of the processing plate 112.

[0037] In the embodiments of this application, the mounting plate 300 is provided with multiple through holes, each for inserting a sensor 310. Therefore, the receiving end of the sensor 310 is exposed outside the mounting plate 300, while the wiring terminal is located in the space between the mounting plate 300 and the housing 100. Each sensor 310's wiring terminal is connected to a data line, which passes through a wire hole on the partition 110 and connects to the processing unit on the processing board 112. The processing unit encodes the natural electromagnetic pulse signal transmitted by the data line and stores it in a storage unit so that after the device is brought back to the laboratory, the data in the storage unit can be read through the data interface provided on the outer side of the housing 100 for subsequent analysis.

[0038] Furthermore, the processing unit can be an STM32 series microcontroller, while the storage unit can be a mechanical hard drive or a solid-state drive. A metal shielding layer is also required on the inner side of the enclosure 100 to shield electromagnetic signals from outside the enclosure 100, preventing adverse effects on electronic devices such as the processing board 112.

[0039] The support rod 107 is preferably an electrically telescopic rod, with its bottom end rotatably connected to the top surface of the partition 110, and its top end rotatably connected to the bottom surface of the mounting plate 300 or a hinge 302. This rotatable connection allows the support rod 107 to swing slightly left and right during extension or retraction when the resistance on both sides is inconsistent, ensuring that the mounting plate 300 can rotate inward or outward normally.

[0040] Furthermore, the number of mounting plates 300 can be even or odd. If there is an even number, there must be at least four, and if there is an odd number, there must be at least three. When an even number of mounting plates 300 is used, one hinge 302 will be located in the center, and the strut 107 can be connected to this centrally located hinge 302. When an odd number of mounting plates 300 is used, one mounting plate 300 will be located in the center, and the strut 107 can be connected to the center of the bottom surface of this mounting plate 300.

[0041] In the embodiments of this application, each mounting plate 300 has an arc-shaped structure, and multiple mounting plates 300 rotate to the outside of the housing 100 to form a semi-cylindrical structure. With this shape of mounting plate 300, each mounting plate 300 has the same size and shape.

[0042] Furthermore, each hinge 302 is provided with a torsion spring. When the mounting plate 300 rotates inward or outward, the torsion spring is compressed. When the mounting plate 300 rotates inward or outward into place, the elastic force of the torsion spring keeps the connection between two adjacent mounting plates 300 smooth.

[0043] During the pushing and pulling process, the distance between the connection point of the mounting plate 300 and the support rod 107 and the connection point of the mounting plate 300 and the housing 100 will change. At this time, the hinge 302 between the two connection points needs to rotate to adapt to this change in distance. After rotating to the correct position, the mounting plate 300 needs to return to its initial state, that is, to form a semi-cylindrical structure. At this time, the torsion spring needs to provide elastic force. Under the action of this elastic force, the mounting plate 300 will rotate in the opposite direction to the pushing and pulling process, and stably maintain the semi-cylindrical structure state.

[0044] It should be understood that the above embodiments are illustrated using a semi-cylindrical mounting plate 300 as an example. In other embodiments, the mounting plate 300 may also be formed into a conical or hemispherical structure to adapt to different needs.

[0045] Furthermore, two control buttons can be installed on the outer surface of the housing 100. These control buttons are connected to the support rod 107. When it is necessary to flip the mounting plate 300 to the outside of the housing 100 for the acquisition of natural electromagnetic pulse signals, the extension button can be pressed. At this time, the support rod 107 will start to extend. After it extends to a suitable length, the extension button can be released. After the acquisition work is completed, the compression button can be pressed. At this time, the support rod 107 will start to shorten. After it shortens to a suitable length, the shortening button can be released.

[0046] In one possible embodiment, each mounting plate 300 is further provided with a side plate 301 at its edge. The side plate 301 is close to the inner side of the housing 100, and the side plates 301 connected on two adjacent mounting plates 300 are in different vertical planes.

[0047] For example, the side panel 301 and the mounting plate 300 are vertically connected, and the bottom end of the side panel 301 is inserted into the inside of the housing 100, so that when the mounting plate 300 is located outside the housing 100, it will also form a relatively enclosed space with the housing 100, reducing the possibility of external dust and other debris entering the inside of the housing 100.

[0048] Furthermore, in order to improve the dustproof performance of the side panel 301, a dustproof brush is provided on the surface of the side panel 301 near the inner side of the housing 100.

[0049] Because the hinge between the two connection points of the mounting plate 300 rotates at a small angle during inward or outward rotation, and this rotation reduces the included angle between adjacent mounting plates 300 (i.e., the rotating hinge forms a protrusion between the two mounting plates 300), if the side plates 301 on these two mounting plates 300 are placed in the same vertical plane, the mounting plate 300 will be unable to rotate due to interference between the two side plates 301. Therefore, this application places the two adjacent side plates 301 in different vertical planes. However, this arrangement of different planes creates a large gap between the side plate 301 and the inner surface of the housing 100, allowing dust to enter. To solve this problem, this application provides a dustproof brush. In its natural state, the dustproof brush can fill the gap between the side plate 301 and the inner surface of the housing 100, reducing the possibility of dust entering. When the side plate 301 rotates, a portion of the dustproof brush undergoes elastic deformation due to the pressure of the side plate 301, thus not affecting the rotation of the side plate 301. After the side panel 301 rotates back to its initial position, the dustproof brush will restore its shape and fill the gap once again.

[0050] In one possible embodiment, the housing 100 is provided with an air inlet 102 and an air outlet 105 on opposite sides, and an air inlet pipe 103 and an air outlet pipe 104 are provided on the inner side of the housing 100 at positions corresponding to the air inlet 102 and the air outlet 105, respectively, and a cooling fan 106 is provided in the air inlet pipe 103 or the air outlet pipe 104.

[0051] For example, the air inlet 102 and the air outlet 105 are respectively provided on the two sides of the housing 100 connected to the mounting plate 300. The air inlet pipe 103 and the air outlet pipe 104 are both arc-shaped plates, and the air inlet pipe 103 and the air outlet pipe 104 are both facing the mounting plate 300. The airflow generated by the cooling fan 106 enters from the air inlet pipe 103, passes through the mounting plate 300, and finally flows out from the air outlet pipe 104.

[0052] To avoid interference between the side panel 301 and the air inlet pipe 103 and air outlet pipe 104 when the side panel 301 rotates into the housing 100, a certain distance needs to be maintained between the air inlet pipe 103 and air outlet pipe 104 and the other two inner sides of the housing 100. This distance must be at least equal to the distance between the side panel 301 and the inner sides of the housing 100. Therefore, when the side panel 301 rotates into the housing 100 along with the mounting plate 300, the side panel 301 will be inserted into the gap between the air inlet pipe 103 and air outlet pipe 104 and the inner sides of the housing 100.

[0053] With the use of arc-shaped air inlet pipe 103 and air outlet pipe 104, air entering horizontally from air inlet 102 will rotate 90 degrees to become vertically upward flowing air. This air flows upward along the inner side of the housing 100. When it comes into contact with the semi-cylindrical mounting plate 300, it will flow along the inner side of the mounting plate 300. In this process, it will carry away the heat generated by the sensor 310 during operation. The air that has absorbed the heat will flow vertically downward along the inner side of the housing 100, and finally, after being guided by air outlet pipe 104, it will become horizontal again and flow out horizontally from air outlet 105.

[0054] Furthermore, dustproof nets are installed on both the air inlet 102 and the air outlet 105.

[0055] In one possible embodiment, a signal conditioning board 111 is also provided between the partition 110 and the inner bottom surface of the housing 100. The signal conditioning board 111 is connected between the sensor 310 and the processing unit. The signal conditioning board 111 has a conditioning circuit, which is used to amplify, filter and perform analog-to-digital conversion on the natural electromagnetic pulse signal.

[0056] For example, since natural electromagnetic pulse signals are relatively weak and contain a certain amount of noise, after processing by the conditioning circuit, a digital signal suitable for direct processing by the processing unit can be obtained.

[0057] In addition to the processing board 112 and the signal conditioning board 111, a battery and a power board can also be installed in the space between the partition 110 and the inner bottom surface of the housing 100. After the battery outputs 12V or 24V power, the power board converts it into the voltage required by the processing unit, storage unit, sensor 310, cooling fan 106 and support rod 107, so that the device in this embodiment can be used normally in the field.

[0058] In one possible embodiment, the top of the housing 100 is provided with a flange 101, and the device also includes a top cover 200, which is inserted into the outside of the flange 101 after the mounting plate 300 is rotated into the housing 100.

[0059] For example, the cross-sectional dimension of flange 101 is smaller than that of housing 100. Therefore, the outer surface of flange 101 is recessed relative to the outer surface of housing 100, but the inner surface of flange 101 is flush with the inner surface of housing 100. The cross-section of top cover 200 is a rectangular ring. The inner dimension of the rectangular ring is the same as the outer dimension of the cross-section of flange 101, and the outer dimension of the rectangular ring is the same as the outer dimension of the cross-section of housing 100. Therefore, top cover 200 can not only fit perfectly into the outside of flange 101, but also be flush with the outer surface of housing 100.

[0060] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0061] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
