Description

Technical Field

[0001] The utility model relates to the technical field of antenna equipment, in particular to an active wired antenna equipment with a Beisan short message function. Background Art

[0002] Currently, the active wired Beisan short message products on the market are all equipped and designed by separating the Beisan frequency band single antenna from the Beisan equipment through the SMA interface. The Beisan frequency band single antenna is placed on the roof or in an open space outdoors, and the Beisan host equipment is all indoors. This easily causes a long distance, which causes great problems for the performance of the Beisan frequency band single antenna. The main problems are:

[0003] 1. The increase in the length of the Beisan antenna caused by the long-distance installation of equipment will cause a significant loss in the gain of the Beisan antenna signal, which may easily cause the Beisan host device to be unable to send and receive short messages normally;

[0004] 2. The length of the single antenna in the northern three frequency bands will result in high equipment costs, thick wires, and difficulty in installation;

[0005] 3. If you use an active single antenna in the Northern Band 3, it will cause more wires to be pulled, and the cost of using pure copper-uranium wire will be higher;

[0006] 4. This type of product generally adds ARM master control to increase the risk of product design and increase costs. Utility Model Content

[0007] 1. Technical Problems Solved

[0008] The technical problem to be solved by the utility model is that the existing Beisan antenna equipment has large gain loss, high cost and is difficult to install.

[0011] The antenna device includes a power module, a data conversion module, a BeiDou module and a BeiDou antenna.

The data conversion module is signal-connected to the power module and the BeiDou module. The BeiDou module is signal-connected to the BeiDou antenna. The BeiDou module is also signal-connected to a BeiDou card.

[0018] 2. Combine the single antenna of the Beisan frequency band with the Beisan module to make an active wired antenna device with Beisan short message function, which communicates with the indoor Beisan host through the RS422 serial port, solving the problems of high cost of long-distance cable pulling and large antenna gain loss;

[0019] 3. Use a common data cable with power supply and RS422 to solve the problems of multiple cables, high cost, thick cables and difficult installation;

[0023] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0024] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The utility model will now be further described in conjunction with the accompanying drawings.

[0028] Combined with Figure 1 The antenna device includes a power module, a data conversion module, a Beisan module and a Beisan antenna. The power module is electrically connected to the Beisan host, the data conversion module and the Beisan module. The data conversion module uses the chip SIT3490E. The power module is connected to the Beisan host via RS422. The data conversion module is signal-connected to the power module and the Beisan module. The Beisan module integrates an RDSS RF transceiver chip, a power amplifier circuit and an LNA amplifier circuit. The Beisan module is signal-connected to the Beisan antenna, and the Beidou card is also signal-connected to the Beisan module.

[0029] The BeiDou 3 antenna is mainly used to connect BeiDou satellites to the network and transmit BeiDou 3 short message data;

[0030] The BeiDou-3 module integrates RDSS RF transceiver chip, power amplifier and LNA amplifier, which can realize the BeiDou-3 regional and BeiDou-2 short message data communication functions.

[0031] The data conversion chip uses SIT3490E, which is mainly used to convert the TTL level of the Beisan short message data into the RS422 level required by the Beisan host.

[0032] The power module mainly solves the Beisan short message data communication, power supply wire, and connection function with the internal Beisan host.

[0033] Beidou cards are mainly used for user identity authentication and device identification before they can access the network and send and receive short message data normally.

[0034] When in use, the Beisan short message process is sent through the Beisan host. The Beisan host connects the short message data to the external active wired antenna device with Beisan short message function through a wire with power supply and RS422 function. The data is converted by the data conversion chip SIT3490E and sent to the Beisan module. Then, the Beisan antenna transmits it to the Beidou satellite, and then the short message data is transmitted to the user or user platform for Beidou short message data communication.

[0035] By connecting to the Beisan short message data through the Beisan host, when the user or user platform sends short message data, after the active wired antenna device with Beisan short message function is connected to the network, the user or user platform can directly send short message data. After the Beisan antenna receives the satellite short message data, it is transmitted to the Beisan module. After the data is converted by the data conversion chip SIT3490E, it is connected to the internal Beisan host device through a cable with power supply and RS422 function for Beidou short message data communication.

[0036] The utility model and its implementation are described, and such description is not restrictive. The drawings are only one of the implementations of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and implementation example similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
