Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless communication technology, specifically to a Beidou communication and positioning one-line antenna. Background Technology
[0002] BeiDou short message communication, as a type of wireless communication, is widely used in rail transit, vehicle and ship applications, emergency rescue, and other fields. It is particularly useful in remote areas without public network coverage, such as oceans, mountains, deserts, and the Gobi Desert.
[0003] In related technologies, short message communication used on high-speed trains currently typically employs passive and active antennas. Passive antennas, lacking electronic components and complex circuits, are more stable and reliable, but their reception and transmission of weak signals, as well as their anti-interference performance, are relatively poor. Active antennas, compared to passive antennas, offer significant improvements in the reception and transmission of weak signals and their anti-interference performance. However, the complex electronic circuits within active antennas can experience mutual interference, making it impossible to ensure normal reception and transmission of short message communication, resulting in poor stability. Furthermore, active antennas have complex wiring and are difficult to install.
[0004] Therefore, for short message communication using active antennas, there is an urgent need for a BeiDou communication and positioning one-line antenna that adopts an active one-line communication method to meet the functions of receiving and transmitting short message communication and receiving GNSS satellite signals, thereby improving the stability and reliability of communication and accurate satellite signal reception. Utility Model Content
[0005] The purpose of this utility model is to provide a Beidou communication and positioning one-line antenna to solve at least one aspect of the problems and defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A Beidou communication and positioning one-line antenna, comprising:
[0008] The base and the outer cover, wherein an active circuit board is provided on the top of the base;
[0009] The top of the active circuit board is electrically connected to a first receiving array and a second receiving array that are stacked together.
[0010] The base has an RF port at its bottom, and the active circuit board is electrically connected to the RF port.
[0011] The BeiDou communication and positioning one-line antenna according to this scheme has at least the following technical effects:
[0012] This Beidou communication and positioning one-line antenna connects the first and second receiving arrays to an active circuit board, and then connects the active circuit board to the radio frequency port. Using an active one-line communication method, only one feeder line is needed between the active circuit board and the radio frequency port to meet the functions of receiving and transmitting short message communication and receiving GNSS satellite signals. It greatly simplifies wiring, reduces construction difficulty, ensures the ability to receive and transmit weak signals and the ability to resist interference, and improves the stability and reliability of communication and accurate satellite signal reception. Thus, it provides communication support for related industries and operations, rescue and other activities in special environments.
[0013] As a further embodiment of this utility model: the first receiving array is a Beidou short message communication receiving array, the second receiving array is a shared array of Beidou short message communication transmitting array and satellite positioning signal receiving array, and the second receiving array is stacked on top of the first receiving array.
[0014] The first receiving array is for BeiDou short message communication, while the second receiving array is a shared array for both BeiDou short message communication transmission and satellite positioning signal reception. The second receiving array is stacked on top of the first receiving array. The first receiving array is dedicated to receiving BeiDou short message communication signals, while the second receiving array is responsible for both transmission and positioning signal reception. Their functions are clearly defined and work in tandem. During short message communication, the first receiving array focuses on receiving information, while the second receiving array transmits, improving communication efficiency and accuracy. Furthermore, the second receiving array can also receive satellite positioning signals, enabling the device to obtain accurate location information while communicating, ensuring the coordinated operation of communication and positioning functions. Simultaneously, this multi-functional integration reduces complex wiring, making the antenna structure more compact and meeting the space-constrained requirements of high-speed rail applications.
[0015] As a further embodiment of this utility model: a cover plate is provided on the top of the second receiving array, and fasteners are provided on the cover plate. The cover plate connects the signal pins of the second receiving array and the signal pins of the first receiving array to the active circuit board respectively through the fasteners.
[0016] By installing a cover plate on top of the second receiving array, and fasteners on the cover plate, the signal pins of the second receiving array and the signal pins of the first receiving array are connected to the active circuit board respectively through the cover plate and the fasteners. This ensures a stable connection between the signal pins of the first receiving array and the signal pins of the second receiving array and the active circuit board, preventing the signal pins from becoming loose or disconnected from the active circuit board due to vibration or impact during the operation of the high-speed train. This ensures the stable operation of Beidou short message communication and satellite positioning signal reception and transmission functions.
[0017] As a further improvement of this utility model, a waterproof rubber pad is provided at the bottom of the base.
[0018] By installing a waterproof rubber pad at the bottom of the base, water and moisture can be effectively prevented from seeping into the antenna, avoiding electrical short circuits or corrosion of the antenna components due to water seepage, which could lead to equipment failure. In addition, the waterproof rubber pad has a certain degree of elasticity, which can play a role in buffering and shock absorption, reducing the vibration and impact of the antenna during high-speed rail operation, and ensuring the stability and reliability of the antenna function.
[0019] As a further improvement of this utility model, a waterproof and breathable valve is provided at the bottom of the base and on one side of the radio frequency port.
[0020] During operation, high-speed trains frequently experience changes in altitude and temperature. To prevent pressure differences between the inside and outside of the antenna caused by these environmental changes—excessive pressure differences could damage the antenna's internal sealing structure and electronic components—a waterproof and breathable valve is installed at the bottom of the base, near the RF port. This valve allows air to enter and exit the antenna, maintaining a pressure balance between the inside and outside. Simultaneously, the antenna generates heat during operation. When the ambient temperature drops, internal moisture can easily condense into water droplets, affecting the performance of electronic components and potentially causing short circuits. The waterproof and breathable valve allows moisture to escape from the antenna, keeping the internal air dry, reducing the likelihood of condensation, lowering the risk of equipment failure due to humidity, ensuring antenna performance stability, and extending the antenna's lifespan.
[0021] As a further embodiment of this utility model: the base is provided with a groove, and the edge of the outer cover is embedded in the groove.
[0022] Because the base has grooves, the edge of the outer cover is embedded in the grooves. The grooves provide a stable connection between the base and the outer cover, making the outer cover and the base tightly connected and not easy to separate. This can effectively resist the vibration or impact of high-speed train operation, prevent the outer cover from shaking or falling off, and provide long-term stable protection for the first and second receiving arrays, thereby ensuring the stability of short message communication reception, transmission and GNSS satellite signal reception functions.
[0023] As a further improvement of this utility model, a sealing ring is also provided in the groove.
[0024] Because a sealing ring is also provided in the groove, the sealing performance at the connection between the base and the outer cover can be effectively improved, preventing moisture, dust and other substances from entering the antenna. This provides a relatively closed and clean environment for the electronic components inside the antenna, preventing corrosion of key components such as the active circuit board, the first receiving array and the second receiving array, and ensuring the antenna's performance and lifespan.
[0025] As a further improvement of this utility model, the outer cover is made of a composite material with good weather resistance and impact resistance.
[0026] Because the outer casing is made of a composite material with good weather resistance and impact resistance, preferably modified nylon, the casing can be used for a long time under different climatic conditions without significant performance degradation, ensuring the integrity of its appearance and the stability of its performance. Furthermore, the casing can withstand large impact forces without being damaged, effectively protecting the internal components of the antenna. At the same time, modified nylon has high wave transmittance, allowing electromagnetic waves to pass through the casing smoothly, ensuring the signal transmission quality of the antenna, thereby ensuring the normal operation of the antenna.

[0041] like Figure 1-3 The present invention, as shown in the embodiment, provides a Beidou communication and positioning one-line antenna, comprising: a base 1 and an outer cover 2. An active circuit board 3 is provided on the top of the base 1. A first receiving array 4 and a second receiving array 5 are electrically connected to the top of the active circuit board 3 respectively. An RF port 6 is provided at the bottom of the base 1, and the active circuit board 3 is electrically connected to the RF port 6.
[0042] Specifically, this Beidou communication and positioning one-line antenna electrically connects the first receiving element 4 and the second receiving element 5 to the active circuit board 3, and then electrically connects the active circuit board 3 to the radio frequency port 6. Using an active one-line communication method, only one feeder line is needed between the active circuit board 3 and the radio frequency port 6 to meet the functions of receiving and transmitting short message communication and receiving GNSS satellite signals. This greatly simplifies wiring, reduces construction difficulty, ensures the ability to receive and transmit weak signals and the ability to resist interference, and improves the stability and reliability of communication and accurate satellite signal reception. Thus, it provides communication support for related industries and operations, rescue and other activities in special environments.
[0043] According to an embodiment of the present invention, the first receiving array 4 is a BeiDou short message communication receiving array, and the second receiving array 5 is a shared array for both BeiDou short message communication transmitting array and satellite positioning signal receiving array. The second receiving array 5 is stacked on top of the first receiving array 4.
[0044] Specifically, the first receiving array 4 is a BeiDou short message communication receiving array, while the second receiving array 5 is a shared array for both BeiDou short message communication transmission and satellite positioning signal reception. The second receiving array 5 is stacked on top of the first receiving array 4. The first receiving array 4 is dedicated to receiving BeiDou short message communication signals, while the second receiving array 5 is responsible for transmission and positioning signal reception. Their functions are clearly defined and they cooperate effectively. During short message communication, the first receiving array 4 focuses on receiving information, while the second receiving array 5 transmits, improving communication efficiency and accuracy. Furthermore, the second receiving array 5 can also receive satellite positioning signals, enabling the device to obtain accurate location information while communicating, ensuring the coordinated operation of communication and positioning functions. Simultaneously, it achieves multi-functional integration, reduces complex wiring, and makes the antenna structure more compact, meeting the space-constrained application requirements of high-speed trains.
[0045] Furthermore, such as Figure 3 and Figure 4 As shown, a cover plate 7 is provided on the top of the second receiving array 5, and a fastener 8 is provided on the cover plate 7. The cover plate 7 connects the signal pins of the second receiving array 5 and the signal pins of the first receiving array 4 to the active circuit board 3 through the fastener 8.
[0046] Specifically, a cover plate 7 is installed on the top of the second receiving array 5, and fasteners 8 are installed on the cover plate 7. The cover plate 7 connects the signal pins of the second receiving array 5 and the signal pins of the first receiving array 4 to the active circuit board 3 through the fasteners 8. This ensures that the signal pins of the first receiving array 4 and the signal pins of the second receiving array 5 are stably connected to the active circuit board 3, preventing the signal pins from becoming loose or disconnected from the active circuit board 3 due to vibration or impact during the operation of the high-speed train. This ensures the stable operation of the Beidou short message communication and satellite positioning signal reception and transmission functions.
[0047] Furthermore, such as Figure 5 As shown, a waterproof rubber pad 9 is provided at the bottom of the base 1.
[0048] Specifically, by setting a waterproof rubber pad 9 at the bottom of the base 1, water and moisture can be effectively prevented from seeping into the antenna from the bottom of the base 1, avoiding electrical short circuits or corrosion of the antenna components due to water seepage, which could lead to equipment failure. In addition, the waterproof rubber pad 9 has a certain degree of elasticity, which can play a role in buffering and shock absorption, reducing the vibration and impact of the antenna during high-speed rail operation, and ensuring the stability and reliability of the antenna function.
[0049] Furthermore, a waterproof and breathable valve 10 is provided at the bottom of the base 1 and on one side of the radio frequency port 6.
[0050] Specifically, high-speed trains frequently experience changes in altitude and temperature during operation. To prevent pressure differences between the inside and outside of the antenna caused by these environmental changes—excessive pressure differences could damage the antenna's internal sealing structure and electronic components—a waterproof and breathable valve 10 is installed at the bottom of the base 1, located on one side of the RF port 6. By controlling the waterproof and breathable valve 10, air can enter and exit the antenna, achieving a balance of pressure inside and outside the antenna. Simultaneously, the antenna generates heat during operation. When the ambient temperature drops, internal moisture can easily condense into water droplets, affecting the performance of electronic components and even causing short circuits. The waterproof and breathable valve 10 allows moisture to escape from the antenna, keeping the internal air dry, reducing the possibility of moisture condensation, lowering the risk of equipment failure due to humidity, ensuring antenna performance stability, and extending the antenna's lifespan.
[0051] According to an embodiment of the present invention, a groove is provided on the base 1, and the edge of the outer cover 2 is embedded in the groove.
[0052] Specifically, since the base 1 is provided with a groove, the edge of the outer cover 2 is embedded in the groove. The groove provides a stable connection between the base 1 and the outer cover 2, making the outer cover 2 and the base 1 tightly connected and not easy to separate. It can effectively resist the vibration or impact of the high-speed train during operation, prevent the outer cover 2 from shaking or falling off, and provide long-term stable protection for the first receiving array 4 and the second receiving array 5, thereby ensuring the stability of the short message communication reception, transmission and GNSS satellite signal reception functions.
[0053] Furthermore, such as Figure 4 As shown, a sealing ring 11 is also provided in the groove.
[0054] Specifically, since a sealing ring 11 is also provided in the groove, it can effectively improve the sealing performance at the connection between the base 1 and the outer cover 2, prevent moisture, dust and other substances from entering the antenna, provide a relatively closed and clean environment for the electronic components inside the antenna, prevent corrosion of key components such as the active circuit board 3, the first receiving array 4 and the second receiving array 5, and ensure the performance and life of the antenna.
[0055] It should also be noted that the outer cover 2 is made of a composite material with good weather resistance and impact resistance; the specific composite material is modified nylon.
[0056] Specifically, because the outer cover 2 is made of a composite material with good weather resistance and impact resistance, specifically modified nylon, the outer cover 2 can be used for a long time under different climatic conditions without significant performance degradation, ensuring the integrity of its appearance and the stability of its performance. Furthermore, the outer cover 2 can withstand large impact forces without being damaged, effectively protecting the internal components of the antenna. At the same time, modified nylon has high wave transmittance, allowing electromagnetic waves to pass smoothly through the outer cover 2, ensuring the signal transmission quality of the antenna, thereby ensuring the normal operation of the antenna.
[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
