[0038] In this application, two fixing seats 312 are oppositely arranged on the side of the connecting plate 301 away from the connecting shaft 306. The fixing seats 312 on adjacent connecting plates 301 are rotatably connected to the connecting member 317. A through hole is formed in the fixing seat 312, and a plug rod 313 is penetrated through the through hole. The plug rod 313 is slidably matched with the fixing seat 312.

[0040] As Figure 2 shown, in this application, the limiting mechanism includes a first limiting slide rail 201. Two second limiting slide rails 202 are oppositely arranged on both sides of the first limiting slide rail 201. A first moving body 203 is slidably connected to the first limiting slide rail 201. A second moving body 204 is slidably connected to the second limiting slide rail 202. A second sliding groove 205 is formed on the top surface of the second moving body 204. Connecting rods 206 are arranged on both sides of the first moving body 203, and the connecting rods 206 are slidably matched with the second sliding groove 205.

When the connecting rods 206 move, they will push the second moving body 204 to move along the second limiting slide rail 202. The installation cylinder surrounded by the connecting plate 301 is abutted by the two second moving bodies 204 to improve the installation stability.

[0041] In a possible embodiment, a threaded rod can also be used to replace the hydraulic rod, so that the threaded rod is in threaded cooperation with the base 2, and the end of the threaded rod extends to the outside of the base 2.

[0042] In this application, both of the two second limit sliding rails 202 are inclined, and the ends close to the outer side of the installation groove are close to each other; the inclination of the second limit sliding rails 202 enables the two second moving bodies 204 to move obliquely when moving, so as to realize the clamping action.

[0043] The connecting rod 206 includes a horizontal portion and an inclined portion which are connected to each other. The inclined portion is in sliding fit with the second sliding groove 205.

The inclined portion of the connecting rod 206 is arranged to facilitate the cooperation with the second moving body 204, so that the second moving body 204 can move obliquely, and it is convenient for the mutual sliding between the second moving body 204 and the inclined portion during movement.

[0044] In this application, multiple groups of anti-slip ridges 316 are arranged on the inner side of the connecting plate 301 to increase the friction between the connecting plate 301 and the installation column body.

[0045] In the synchronous timekeeping system of this application, the master clock source adopts a temperature-compensated crystal oscillator, and its frequency stability does not exceed 0.5 ppm to ensure the high precision and stability of the clock source; among them, through the GNSS receiving module, global time synchronization is realized to ensure that the system time is consistent with the global standard time, and the accuracy and reliability of time synchronization are improved; clock drift calibration circuit module: designed with an automatic clock drift calibration circuit, which can monitor the drift situation of the clock source in real time and automatically calibrate it to maintain the accuracy and stability of the system time; backup power management module: integrated with a backup power management unit to provide continuous power support for the system in case of main power failure or power outage, ensuring that the system can operate normally and maintain time synchronization. The present invention provides a design of a synchronous timekeeping system with high precision and high stability. By integrating a temperature-compensated crystal oscillator, a GNSS receiving module, an automatic clock drift calibration circuit module, and a backup power management module, the accuracy and reliability of time synchronization are improved, and it can be applied to various application scenarios of the Internet of Things and communication systems.

[0046] In the spread spectrum communication system of this application, the DSSS (Direct Sequence Spread Spectrum) modulation module uses a 63-bit spreading code to ensure that the system processing gain reaches 18 dB, and the chip rate is set to 2 Mcps to improve the data transmission rate and anti-interference ability; Frequency planning module: Operating frequency band: Select 470 - 510 MHz as the operating frequency band of the system, which is suitable for a variety of wireless communication applications. Channel bandwidth: The bandwidth of each channel is 2 MHz to ensure the stability and efficiency of data transmission. Number of sub-channels: 16 sub-channels are planned within the given frequency band to meet the needs of multi-user simultaneous communication and improve the spectrum utilization rate. Adaptive power control module: Power level setting: The maximum transmit power is 20 dBm to ensure a stable communication connection even at long distances or in complex environments; The power adjustment step is 2 dB to achieve fine power adjustment to adapt to different communication environments; The dynamic range reaches 30 dB to ensure that the system can operate normally under various signal strengths. RSSI monitoring strategy: The sampling period is 100 ms to monitor the Received Signal Strength Indicator (RSSI) in real time to quickly respond to signal changes; The decision threshold is set to -95 dBm as a reference for adjusting the transmit power; The handover hysteresis is 3 dB to avoid frequent power adjustments caused by signal fluctuations and improve the system stability.

[0047] This device integrates and installs the synchronous time synchronization system and the spread spectrum communication system in the housing 1, and uses satellite signals, such as GNSS or Beidou, to perform unified time synchronization on various systems to ensure that the clocks are completely unified, providing an accurate time reference for the systems in fields such as power and communication, and ensuring the normal operation of the systems and the accuracy of data.

[0048] Improve anti-interference ability: By expanding the signal spectrum width, enhance the anti-interference and confidentiality of the communication system.

[0049] Achieve precise measurement: Have high-precision measurement capabilities, suitable for application scenarios such as navigation and positioning. Ensure communication security: The characteristics of low detection probability and concealment help to ensure the security of the communication process.

[0050] When in use, the device is installed on the mounting column at the target position through the mounting structure 3. For outdoor installation, it can also be fixed on the tree trunk, and the installation is convenient. During installation, first select a plurality of connecting plates 301 according to the diameter of the column to be installed, connect the plurality of connecting plates 301 end to end, pull the insertion rod 313 outward so that the connecting member 317 enters the inside of the fixed seat 312. At this time, the spring 314 is compressed. Push the connecting member 317 between the two fixed seats 312, release the insertion rod 313, and under the elastic force of the spring 314, push the insertion shaft 315 into the hole of the connecting member 317 to realize the rotational connection between the fixed seat 312 and the connecting member 317. When connecting the last two connecting plates 301, you can choose to remove the hanging rope 307 on some of the connecting plates 301 from the connecting shaft 306, then slide the movable plate 302 relative to the connecting plate 301 so that the last two connecting plates 301 can be in contact connection, and then hang it on the inner sleeve shaft 309 through the hanging rope 307. Rotate the inner sleeve shaft 309 to wind the hanging rope 307 so that the hanging rope 307 is in a taut state, thereby realizing the stable installation of the connecting plate 301. Finally, adjust the limiting mechanism in the base 2 so that the ends of the two second moving bodies 204 are in contact with the outer wall of the mounting column, further improving the installation stability and preventing the connecting plate 301 from slipping.
