Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protection equipment more particularly, relate to a portable terminal of big dipper receiver. BACKGROUND

[0002] At present, the application field of unmanned aerial vehicle (UAV) is continuously expanding with the rapid development of UAV technology, from aerial surveying and mapping to logistics distribution, from emergency rescue to agricultural plant protection, UAV plays an important role in various industries. In the UAV system, accurate positioning and stable communication are crucial, which highly depends on the performance of ground Beidou receiver and its supporting antenna.

[0003] At present, the common integration mode of ground Beidou receiver and high-precision antenna, communication antenna is to be integrated with ground command and control station. However, this mode has many disadvantages. First of all, the ground command and control station is usually large in size and complex in structure, which is not easy to move. In the early test stage of UAV system, the positioning accuracy, communication stability and other key performance indicators of UAV need to be tested repeatedly in different places and different environments. However, due to the difficulty of rapid migration of ground station, the test team has to spend a lot of time and effort to rebuild the test environment, which seriously affects the test efficiency of UAV system in the early stage. For example, when testing the influence of signal shielding of UAV in mountainous environment on positioning, due to the fixed position of ground station, it is not flexible to choose the best test point, which leads to incomplete test data and difficulty in accurately evaluating the positioning performance of UAV in complex terrain.

[0004] Secondly, this integrated mode reduces the practical efficiency of Beidou differential positioning and short message link. In actual application, UAV needs to obtain high-precision positioning information in real time to ensure flight safety and accurate task execution, and relies on short message link to realize reliable communication with the ground. However, the fixed integration mode of ground station, receiver and antenna makes the signal transmission susceptible to environmental interference, and it is difficult to quickly adjust parameters according to the actual flight scene, which affects the signal quality and transmission efficiency of Beidou differential positioning and short message link. In some UAV operation scenes with high requirements for positioning accuracy, such as power inspection and surveying and mapping, the UAV cannot accurately identify the target position due to insufficient positioning accuracy, which increases the operation risk and error. In terms of communication, the low efficiency of short message link may cause delay or interruption of command transmission, affecting the flight control of UAV.

[0005] In addition, the conventional Beidou receiver has significant problems in security, structural design and portability. In some special environments with high requirements for equipment security, such as places with flammable and explosive substances, ordinary receiver terminals lack explosion-proof design and have serious safety hazards. Once an accident occurs, it may cause serious accidents. The existing portable terminal also has defects in structural design. The internal components are not arranged reasonably, which makes the connection and operation between components inconvenient, affecting the use efficiency of the equipment. The data transmission interface, power interface and other interfaces on the panel are distributed randomly, and the user cannot quickly and accurately find the corresponding interface when performing data transmission or power connection, wasting a lot of time. At the same time, the installation and layout of the antenna are not scientific, and different function antennas interfere with each other, affecting the signal receiving and transmitting performance of the Beidou receiver, and thus reducing the accuracy of positioning and communication. The size and weight of the conventional terminal are not reasonably designed, and the operator carries it inconveniently in the scene that needs to be moved frequently, increasing the work burden.

[0006] In summary, it is of great practical significance to develop a Beidou receiver portable terminal that is safe and reliable, reasonably structured, easy to carry, and can effectively solve the problem of ground station integration, which will greatly promote the wide application and development of unmanned aerial vehicle technology in more complex scenarios.

[0045] In this embodiment, the antenna 5 is a Beidou RNSS high-precision antenna, and the antenna 6 is a Beidou RDSS communication antenna. The Beidou RNSS high-precision antenna is an antenna used for receiving signals of the Beidou satellite navigation system, which has the characteristics of high precision, high sensitivity, strong anti-interference ability, etc. The Beidou RNSS high-precision antenna determines the position, speed and time of the receiving device by receiving and processing signals sent by the Beidou satellite. Specifically, after receiving the satellite signal, the antenna converts it into an electrical signal, which is then transmitted to the Beidou receiver through a cable. The Beidou receiver amplifies, filters and decodes the signal, and finally obtains the positioning information. The Beidou RNSS high-precision antenna can provide centimeter-level or even millimeter-level positioning accuracy. The Beidou RDSS communication antenna is an antenna used for the Beidou satellite navigation system, mainly used to realize the communication function between the Beidou satellite and the ground user. The Beidou RDSS communication antenna can receive radio frequency signals from the Beidou satellite through specific antenna structure and circuit design. These signals contain navigation information, short message data, etc. sent by the satellite; the received radio frequency signal is amplified by a low-noise amplifier to improve the quality and strength of the signal. Then, the signal is filtered by a filter to remove noise and interference signals. Next, the signal is demodulated and decoded to convert it into a digital signal for subsequent processing and analysis; when sending short messages or other data is needed, the Beidou RDSS communication antenna will convert the encoded and modulated digital signal into a radio frequency signal and transmit it through the antenna. The transmitted radio frequency signal can be received by other ground users after being forwarded by the satellite.

The PPS interface (second pulse interface) is used for high-precision time synchronization. The network transmission interface 12 is used for transmitting Beidou differential positioning information and unmanned aerial vehicle platform flight control remote control telemetry data.

[0048] In this embodiment, the network transmission interface 12 is an RJ-45 interface.
