Description

Technical Field

[0001] This utility model belongs to the technical field of train communication equipment, and in particular relates to a train-mounted integrated communication device. Background Technology

[0002] Trains typically carry BeiDou-3 communication antennas, Tiantong satellite communication antennas, LoRa antennas, and 4G / 5G antennas. To prevent mutual interference, these are usually installed in different locations on the train. Selecting and installing four antennas independently results in cumbersome construction, requires a large installation area, and is particularly difficult to implement within the limited space on the locomotive roof. Furthermore, in actual use, the antennas operate on similar frequency bands, which can easily cause interference and fail to meet design requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a train-mounted integrated communication device. It combines four types of antennas and mounts them together on a circular base plate, and protects them with an antenna cover. The antennas in the antenna combination do not interfere with each other, reducing installation space, reducing construction difficulty, reducing the area occupied by multiple antennas, and using the mounting bracket for shielding to improve communication efficiency. It solves the problems of existing multiple antennas installed in multiple positions on the train, which leads to installation trouble and easy mutual interference.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a train-mounted integrated communication device, comprising a base circular plate, an antenna cover, an antenna assembly, and a radio frequency switch module. The upper surface of the base circular plate has a rubber ring groove, within which a sealing rubber ring is embedded. The bottom of the antenna cover has a mounting edge that presses against the sealing rubber ring and is secured with bolts. A bracket is fixedly mounted around the bottom edge of the base circular plate. A hollow mounting post is located at the center of the upper surface of the base circular plate. The bottom of the antenna assembly is mounted on the mounting post. The antenna assembly includes a BeiDou-3 communication antenna, a Tiantong satellite communication antenna, a LoRa antenna, and a 4G / 5G antenna. An adjustment box is located at the bottom of the base circular plate, within which the radio frequency switch module is installed. The radio frequency switch module is electrically connected to the antenna assembly. A removable cover is installed on the side opening of the adjustment box. The radio frequency switch module is electrically connected to the train's locomotive-mounted main unit.

[0006] The present invention is further configured such that the antenna assembly is mounted on an antenna frame, the antenna frame including a cylindrical column and multiple layers of shielding circular plates, the multiple layers of shielding circular plates being equally spaced on the cylindrical column, and a Beidou-3 communication antenna, a Tiantong satellite communication antenna, a LoRa antenna and a 4G / 5G antenna being fixedly installed on the upper surface of the base circular plate and the upper surface of each layer of shielding circular plate, respectively. Each layer of shielding circular plate will cover and shield the antenna of the lower layer, and the cylindrical column is provided with multiple cable routing holes.

[0007] The present invention is further configured such that the Beidou-3 communication antenna, the Tiantong satellite communication antenna, the LoRa antenna, and the 4G / 5G antenna are all arranged in a circular ring with no fewer than three antennas.

[0008] The present invention is further configured such that the diameter of the multi-layered shielding circular plates gradually decreases from bottom to top, so that the antenna frame is in the shape of a frustum, and the Beidou-3 communication antenna, Tiantong satellite communication antenna, LoRa antenna and 4G / 5G antenna are distributed in a frustum shape from the base circular plate upwards.

[0009] The present invention is further configured such that the radio frequency switch module is used to realize time-division and frequency-division switching of the Beidou-3 communication antenna, Tiantong satellite communication antenna, LoRa antenna and 4G / 5G antenna, or to simultaneously activate the Beidou-3 communication antenna, Tiantong satellite communication antenna, LoRa antenna and 4G / 5G antenna.

[0010] The present invention is further configured such that the antenna cover 1 is a transparent semi-elliptical plastic cover.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model connects four types of antennas to the radio frequency switch module respectively. The locomotive host can control the radio frequency switch module to realize the time-division and frequency-division switching of the antennas or simultaneous conduction according to the set requirements. Structurally, multiple antennas can be installed in one position, which reduces the difficulty of antenna installation and construction, reduces the failure rate of antennas, and reduces the construction area occupied by multiple antennas.

[0013] 2. This utility model improves communication performance by shielding the mutual interference between four types of antennas through the antenna frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model is a train-mounted integrated communication device, including a base circular plate 2, an antenna cover 1, an antenna assembly, and a radio frequency switch module. The upper surface of the base circular plate 2 is provided with a rubber ring groove 21, and a sealing rubber ring 6 is embedded in the rubber ring groove 21. The bottom of the antenna cover 1 is provided with a mounting edge 11, which is pressed on the sealing rubber ring 6 and fixed with bolts. A bracket 3 is fixedly installed around the bottom edge of the base circular plate 2. A hollow mounting post 22 is provided at the center of the upper surface of the base circular plate 2. The bottom of the antenna assembly is installed on the mounting post 22. The antenna assembly includes a Beidou-3 communication antenna 23, a Tiantong satellite communication antenna 53, a LoRa antenna 54, and a 4G / 5G antenna 55. The bottom of the base circular plate 2 is provided with an adjustment box 4, and the radio frequency switch module is installed in the adjustment box 4. The radio frequency switch module is electrically connected to the antenna assembly. A detachable cover 41 is installed on the side opening of the adjustment box 4. The radio frequency switch module is electrically connected to the train locomotive-mounted host.

[0024] During installation, first install bracket 3 on base plate 2, then install bracket 3 on the train roof. Assemble the cable below base plate 2, connect it to the RF switch module through the adjustment box, pass it through the mounting post, and connect it to the antenna assembly. Then, cover it with antenna cover 1 and fix it with bolts to complete the installation. The four types of antennas—BeiDou-3 communication antenna 23, TianTong satellite communication antenna 53, LoRa antenna 54, and 4G / 5G antenna 55—are assembled together for centralized management. They can also achieve time-division and frequency-division switching of antenna conduction or simultaneous conduction by controlling the RF switch module. Structurally, multiple antennas can be installed in one location, reducing the difficulty of antenna installation, reducing the antenna failure rate, and minimizing the construction area occupied by multiple antennas.

[0025] The antenna assembly is mounted on the antenna frame 5, which includes a cylindrical column 51 and multiple shielding circular plates 52. The multiple shielding circular plates 52 are equally spaced on the cylindrical column 51. The upper surface of the base circular plate 2 and the upper surface of each layer of shielding circular plates 52 are respectively fixedly mounted with a Beidou-3 communication antenna 23, a Tiantong satellite communication antenna 53, a LoRa antenna 54, and a 4G / 5G antenna 55. Each layer of shielding circular plates 52 will cover and shield the antenna of the lower layer. The cylindrical column 51 is provided with multiple cable routing holes 511.

[0026] The shielding disc 52 can only shield from top to bottom, not from all sides. The emitted signal propagates in a straight line without refraction, ensuring signal reception and transmission from the outside. However, this greatly reduces signal interference between the four types of antennas. The cylindrical column 51 is used for wiring, and cables pass through the wiring holes 511 to each shielding disc 52 to connect with the antenna.

[0027] The Beidou-3 communication antenna 23, Tiantong satellite communication antenna 53, LoRa antenna 54, and 4G / 5G antenna 55 are all arranged in a circular pattern with no fewer than three antennas.

[0028] There should be at least three of each type of antenna, and preferably more than four. Figure 2 and 4 As shown, this is to enable the receiving and sending of signals in all directions.

[0029] The diameter of the multi-layered shielding circular plates 52 gradually decreases from bottom to top, so that the antenna frame 5 is in the shape of a frustum. The Beidou-3 communication antenna 23, Tiantong satellite communication antenna 53, LoRa antenna 54 and 4G / 5G antenna 55 are distributed in a frustum shape from the base circular plate 2 upwards.

[0030] The shielding disc 52 is shaped like a frustum to facilitate signal reception after it enters the antenna radome 1. The antenna is also frustum-shaped to match the shielding disc 52, ensuring effective antenna shielding.

[0031] The radio frequency switch module is used to realize time-division and frequency-division switching of the Beidou-3 communication antenna 23, Tiantong satellite communication antenna 53, LoRa antenna 54 and 4G / 5G antenna 55, or to simultaneously activate the Beidou-3 communication antenna 23, Tiantong satellite communication antenna 53, LoRa antenna 54 and 4G / 5G antenna 55.

[0032] When signal demand is low, antennas can be switched in a time-division and frequency-division manner. When it is necessary to receive signals from multiple frequency bands, all antennas can be switched on to receive signals.

[0033] The antenna cover 1 is a transparent, semi-elliptical plastic cover. It ensures that communication is not affected while also providing protection.
