[0017] See attached document Figures 1-4The railway communication environment optimization device provided by this utility model includes a fixed base 100. Corner fixing blocks 110 for connection are fixed at the outer corners of the fixed base 100. The fixed base 100 can be fixed to the railway wall or tunnel wall by the corner fixing blocks 110 and bolts. A bearing plate 200 is provided above the top of the outer wall of the fixed base 100. Vertical plates 210 are fixed at the top of the outer wall of the fixed base 100 and at corresponding positions on both sides of the bottom of the bearing plate 200. A rotating shaft 220 is rotatably connected between the vertical plates 210 via bearing seats. The bottom sides of the outer wall of the bearing plate 200 are fixedly connected to the outer wall of the rotating shaft 220 via rotating shaft sleeves 230. The rotating shaft 220 can rotate... The bearing plate 200 is rotated by the rotating shaft sleeve 230, thereby adjusting the angle of the flange connecting seat 400. This ensures that the angle between the flange connecting seat 400 and the signal transmission / reception direction and the train travel path is maintained between 0° and 30°, improving signal acquisition efficiency by more than 30%. One end of a telescopic support rod 240 is hinged to each of the four corners of the outer wall of the bearing plate 200. The bottom end of each telescopic support rod 240 is hinged to the corresponding position at the top of the outer wall of the fixed seat 100. The telescopic support rods 240 support both ends of the bearing plate 200. Their hinged connection and telescopic movement prevent jamming of the rotation adjustment of the bearing plate 200. The outer wall of any upright plate 210, away from the rotating shaft 220... One side of each of the vertical plates 210 is rotatably connected to an annular block 211. The side end of the annular block 211 is fixedly connected to the side end of the rotating shaft 220 via a connecting shaft. Curved frames 213 are fixed to the outer wall side of the vertical plate 210 and to the front and rear sides of the annular block 211. Annular grooves 212 are provided on the outer wall side of the annular block 211 at positions corresponding to the curved frames 213. Threaded rods 214 are connected to the outer wall of the curved frames 213 at positions corresponding to the annular grooves 212 via threaded holes. Annular blocks 215 are rotatably connected to the end of the threaded rods 214 near the annular block 211. The outer wall of the annular blocks 215 engages with the inner wall of the annular block 211. Specifically, when personnel need to adjust the angle of the bearing plate 200, they can do so via the reverse... Rotating the threaded rod 214 separates the annular locking block 215 from the inner wall of the annular block 211, allowing the annular block 211 to rotate. This enables the rotating shaft 220 to drive the rotating shaft sleeve block 230 to rotate. After fixing, rotating the threaded rod 214 in the forward direction allows the annular locking block 215 to be inserted into the annular slot 212. The insertion end of the annular locking block 215 and the annular slot 212 can be engaged and locked by setting teeth, thereby fixing the rotating shaft 220. The materials of the annular block 211, the curved frame 213, the threaded rod 214, and the annular locking block 215 can be made of high-strength steel to ensure that they can support and fix the protective shell 300 and the flange connecting seat 400. A signal processing component for processing and transmitting communication signals is mounted on the carrier plate 200. The signal processing component includes a protective housing 300, which is detachably fixed to the top of the outer wall of the carrier plate 200.

The anti-interference unit 311 includes a cavity filter and an interference suppression chip. The cavity filter is connected to the output terminal of the relay unit 313 via a wire, and the interference suppression chip is soldered to the PCB board. The cavity filter, mounted on board B310 and electrically connected to control unit 314, has a passband rejection ratio ≥85dB, capable of filtering clutter interference in the 200-2700MHz frequency band. The interference suppression chip can eliminate sudden electromagnetic interference signals in real time. The spectrum detection unit 312 includes a spectrum sensor and a data transmission interface. The spectrum sensor is soldered onto PCB board 310, and the data transmission interface is embedded in the other side wall of the protective housing 300. The spectrum sensor is electrically connected to control unit 314 via the data transmission interface. The spectrum sensor's detection frequency band covers 800-2700MHz, enabling real-time acquisition of spectrum interference data along the railway line and transmission to control unit 314. The relay unit 313 employs a high-gain signal amplifier with a gain ≥90dB. Supporting dual-band (800MHz, 2100MHz), it is welded to the inside of the protective shell 300 via a stand plate 210. Its input terminal is electrically connected to the antenna module 410, its output terminal is electrically connected to the ring block 211, and its control terminal is electrically connected to the control unit 314.

The main power supply unit is connected to the AC power supply line along the railway line via wires, and the backup power supply is connected in parallel with the main power supply unit via wires. Both are electrically connected to the signal processing module PCB board 310 via wires and are fixed to one side of the mounting base 100. The effect is that the main power supply unit provides a stable DC power supply to the device, and the backup power supply automatically switches when the main power supply is interrupted, providing continuous power for ≥4 hours to avoid communication interruption. The heat dissipation component is a cooling fan, which is fixed to the outer wall of the protective shell 300 with screws.Furthermore, the cooling fan is electrically connected to the control unit 314; A flange connector 400 is fixed to the top of the outer wall of the protective housing 300.

[0018] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel. After the device is powered on, the control unit 314 starts the spectrum detection unit 312, and the spectrum sensor collects spectrum data in the 800-2700MHz frequency band in real time and transmits it to the control unit 314 through the data transmission interface; When an interference signal is detected, the control unit 314 sends a command to the anti-interference unit 311, the cavity filter filters out the corresponding frequency band noise, and the interference suppression chip eliminates sudden interference. Meanwhile, the relay unit 313 amplifies the weak signal received by the antenna module 410 (gain 90dB) and transmits it to the leaky cable through the leaky cable interface to achieve signal coverage in the tunnel; When the main power supply is interrupted, the control unit 314 detects the voltage abnormality and automatically switches to the backup power supply to ensure the device continues to work. During operation, the heat dissipation components run continuously, and the cooling fan dissipates heat to maintain a stable internal temperature.
