Description

Technical Field

[0001] This utility model relates to the field of satellite signal receiving technology, and more specifically, to an integrated device for BeiDou-2 and BeiDou-3. Background Technology

[0002] In recent years, with the development of navigation systems and the gradual implementation of the BeiDou military-to-civilian conversion concept, the application prospects of the BeiDou system are infinitely broad, providing effective support for civilian satellite navigation technology. To accelerate the application of the BeiDou-3 satellite navigation system in ground equipment such as telemetry, tracking, and command (TT&C) and data transmission, and radar, and to expedite the transformation of the new functions and capabilities of the BeiDou-3 system into the capabilities of ground equipment, in accordance with navigation-related requirements, it is necessary to upgrade and transform the time and frequency and navigation positioning equipment of the BeiDou-2 system and foreign navigation systems such as GPS.

[0003] Currently, most second-generation chassis equipment has a single-layer layout. When there are many components, boards, and modules, the arrangement of a single layer or chassis is limited, and most are designed to be used in two interconnected chassis. Therefore, the extra chassis increases production costs. In addition, the equipment also has disadvantages such as low installation integration, inconvenient application, and high production costs. As a result, many products have to use two chassis for internal modules due to insufficient internal space. The chassis does not have portability, and the rack installation space is occupied, resulting in a certain waste of resources.

[0004] Furthermore, there are limitations in the application scenarios and environmental conditions. Some cabinets, with limited installation space, may prevent equipment from being installed, used, or used inconveniently. During maintenance, since the equipment needs to communicate with each other to function, if a component in one cabinet fails and needs to be disassembled, some functions in another cabinet will also become unusable. Some system equipment will then be put on standby due to functional defects, resulting in significant waste of resources, increased time costs, and project delays. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated device for BeiDou-2 and BeiDou-3, which has a high degree of integration.

[0006] This utility model is achieved through the following technical solution:

[0007] An integrated device for BeiDou-2 and BeiDou-3 includes a chassis, a partition, a third-generation signal receiving mechanism, a second-generation signal receiving mechanism, a spatiotemporal isolation plate, and a power supply.

[0010] Two spatiotemporal isolation plates are fixedly installed on the top of the partition, wherein the first spatiotemporal isolation plate is used to isolate the third-generation signal receiving mechanism, and the second spatiotemporal isolation plate is used to isolate the second-generation signal receiving mechanism.

[0011] The power supply is fixedly installed on the inner bottom surface of the chassis, and provides power to both the second-generation and third-generation signal receiving mechanisms.

[0012] Furthermore, the chassis includes a cover plate, a bottom plate, a front plate, a back plate, and two side plates; the two side plates are fixed to the bottom plate with screws, and the two sides of the partition are respectively fixedly connected to the corresponding side plates with screws.

[0013] Multiple locking blocks are fixedly installed on the opposite sides of both side plates, and an L-shaped baffle that cooperates with the locking blocks is provided on the bottom surface of the cover plate.

[0014] The front plate and back plate are fixedly connected to the corresponding end faces of the two side plates by screws.

[0015] Furthermore, the cover plate, bottom plate, front plate, back plate, and two side plates are all integrally molded structures.

[0016] Furthermore, the third-generation signal receiving mechanism includes a code receiving module, a common-view comparison module, and a navigation signal generation module.

Through partitions and spatiotemporal isolation plates, it achieves a high degree of integration and compactness of the second-generation signal receiving mechanism and the third-generation signal receiving mechanism in the upper and lower parts of the chassis, and also achieves physical electromagnetic isolation between the two-generation signal receiving mechanisms, thereby improving the portability of the device.

[0022] In addition, by integrating second-generation and third-generation signal receiving mechanisms into the chassis, this equipment can be used to receive signals from the BeiDou-2 and BeiDou-3 systems, improving the utilization rate of the equipment. Furthermore, when receiving signals from the BeiDou-2 and BeiDou-3 systems, the number of devices required and the size of the equipment are effectively reduced.

[0033] Example 1

[0034] As attached Figure 1 and attached Figure 2 The aforementioned integrated device for BeiDou-2 and BeiDou-3 includes a chassis 1, a partition 2, a third-generation signal receiving mechanism 3, a second-generation signal receiving mechanism 4, a spatiotemporal isolation plate 5, and a power supply 6. The partition 2 is fixedly installed inside the chassis 1, and the inner cavity of the chassis 1 is divided into upper and lower parts by the partition 2, thereby achieving physical isolation between the two parts of the space inside the chassis 1.

[0035] The inner top surface of the chassis 1 is fixedly provided with a third-generation signal receiving mechanism 3 for receiving Beidou-3 system signals; that is, the third-generation signal receiving mechanism 3 is located in the upper half of the space of chassis 1, so that this third-generation to second-generation conversion device can still receive signals sent by Beidou-3 system.

[0036] In addition, the third-generation signal receiving mechanism 3 includes a code receiving module, a common-view comparison module, and a navigation signal generation module. The code receiving module is responsible for receiving signals from the corresponding Beidou-3 satellites. The common-view comparison module is used for time synchronization and comparison of Beidou-3 signals. The navigation signal generation module is used to generate navigation signals for convenient subsequent processing and output.

[0037] The bottom surface of the chassis 1 is fixedly provided with a second-generation signal receiving mechanism 4 for receiving Beidou-2 system signals. That is, the second-generation signal receiving mechanism 4 is located in the lower half of the space of chassis 1. Through the second-generation signal receiving mechanism 4, this device can realize the function of receiving Beidou-2 system signals and complete the third-generation to second-generation conversion operation.

[0038] In addition, the second-generation signal receiving mechanism 4 includes a GNSS receiving board 401, a combiner 402, a time measurement board 404, and a counting board 403. The GNSS receiving board 401 is used to receive GNSS signals, including BeiDou, GPS, etc. The combiner 402 is used to combine signals from different sources. The time measurement board 404 is used to perform time measurement and calibration. The counting board 403 is responsible for counting and data processing.

[0039] In addition, the counting board 403 processes signals including but not limited to pulse signals and frequency signals. It can be used to count the number of signals received within a specific time period, or to perform other types of signal processing and calculations. During the BeiDou-2 signal reception process, the counting board 403 helps verify the integrity and accuracy of the signal, ensuring reliable signal transmission.

[0040] Two spacetime isolation plates 5 are fixedly installed on the top of the partition 2, wherein the first spacetime isolation plate is used to isolate the third-generation signal receiving mechanism 3, and the second spacetime isolation plate is used to isolate the second-generation signal receiving mechanism 4.

[0041] Two spatiotemporal isolation boards 5 physically isolate different functional modules, such as the receiver, combiner 402, time measurement board 404, etc., from other components. This avoids mutual interference between different modules, ensures that each module can work normally, and improves the overall stability and reliability of the equipment. Furthermore, the spatiotemporal isolation board 5 achieves signal isolation between the second-generation signal receiving mechanism 4 and the third-generation signal receiving mechanism 3 through the isolation circuit etched on its surface.

[0042] Furthermore, electromagnetic interference between different modules is a common problem in electronic devices. The spatiotemporal isolation plate 5, through its material properties such as metallic shielding, can effectively block the propagation of electromagnetic waves, reduce electromagnetic interference between modules, and ensure signal purity and accuracy, which is particularly important for navigation and positioning equipment.

[0043] In particular, the spacetime isolation panel 5 helps to achieve functional zoning within the equipment, making the internal structure clearer and facilitating maintenance and upgrades. In this equipment, two spacetime isolation panels 5 are installed on the upper layer, which not only achieves physical isolation but also provides independent space for different functional modules, helping to improve the integration and modularity of the equipment.

[0044] Furthermore, for navigation systems like BeiDou, signal purity directly affects positioning accuracy. The spatiotemporal isolation board 5 ensures isolation between different signal channels, avoiding signal crosstalk and thus guaranteeing high-quality signal transmission. This is crucial for achieving signal isolation and time-frequency consistency verification functions.

[0045] The power supply 6 is fixedly installed on the inner bottom surface of the chassis 1, and the power supply 6 provides power to the second-generation signal receiving mechanism 4 and the third-generation signal receiving mechanism 3 respectively.

[0046] It should be noted that the second-generation signal receiving mechanism 4 and the third-generation signal receiving mechanism 3 are functionally and spatially independent of each other. Therefore, if the second-generation signal receiving mechanism 4 or the third-generation signal receiving mechanism 3 fails, when the chassis 1 is opened for maintenance, it is only necessary to cut off the power supply to the faulty mechanism, and the other signal receiving mechanism can still work, thus ensuring the continuity of project processing.

[0047] Example 2

[0048] The chassis 1 includes a cover plate 101, a bottom plate 102, a front plate 103, a back plate 104, and two side plates 105; the two side plates 105 are fixed to the bottom plate 102 by screws, and the two sides of the partition 2 are respectively fixedly connected to the corresponding side plates 105 by screws.

[0049] Multiple locking blocks 11 are fixedly installed on the opposite sides of the two side plates 105, and the bottom surface of the cover plate 101 is provided with an L-shaped baffle that cooperates with the locking blocks 11.

[0050] The front plate 103 and the back plate 104 are respectively fixedly connected to the corresponding end faces of the two side plates 105 by screws;

[0051] The assembly process of chassis 1 is as follows: First, fix the two side panels 105 to the base plate 102 with screws. Then, fix the second-generation signal receiving mechanism 4 on the base plate 102. Next, fix the partition 2 between the two side panels 105 with screws. Then, install the space-time isolation plate 5 on the partition 2. Then, fix the third-generation signal receiving mechanism 3 on the cover plate 101. Then, place the cover plate 101 on top of the two side panels 105. By pushing and pulling, the bent part of the L-shaped baffle of the cover plate 101 is engaged with the locking block 11. Finally, complete the wiring between the second-generation signal receiving mechanism 4 and the third-generation signal receiving mechanism 3, the power supply 6, the front plate 103 interface and the back plate 104 interface. Finally, by installing the front plate 103 and the back plate 104 on the corresponding end faces of the two side panels 105, a complete cubic chassis 1 is formed.

[0052] Because the cover plate 101 uses a push-pull structure during installation, the use of screws is reduced, making it very convenient and quick to install and maintain.

[0053] In particular, the cover plate 101, bottom plate 102, front plate 103, back plate 104 and two side plates 105 are all integral molded structures, which have the advantages of high strength, good rigidity and strong impact resistance.

[0054] In addition, the main plate 103 is equipped with a display screen 7, a switch 8, and a handle 9. The display screen 7 can be used to display the working status of the second-generation signal receiving mechanism 4 and the third-generation signal receiving mechanism 3, as well as basic information such as the received satellite signals. The switch 8 is used to control the start and stop of the device, that is, the power switch 8 of the power supply 6. The handle 9 is located at both ends of the main plate 103, which facilitates the operation of workers when installing or disassembling the main plate 103.

[0055] As needed, the back plate 104 is equipped with a fan 10, which can realize the circulation of air inside and outside the chassis 1, thereby reducing the temperature inside the chassis 1 and effectively extending the working life of the components inside the chassis 1.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
