Description

Technical Field

[0001] The present invention relates to the technical field of tunnel monitoring, and in particular to a tunnel deformation monitoring and early warning system and a tunnel monitoring method. Background Art

[0002] The tunnel deformation monitoring system is mainly used for tunnel safety monitoring during the construction or operation period. It uses convergence meters, laser rangefinders and other measuring devices to measure and monitor the settlement and deformation of the tunnel vault.

[0003] In the existing technology, the traditional system has only a single sensor measurement device at the local end, which only collects data but does not perform local data judgment, processing, or on-site linkage. The threshold judgment and early warning of the traditional monitoring system must be processed by a remote server platform, industrial computer, etc., and it is impossible to conduct real-time on-site analysis and judgment and make on-site linkage. It is necessary to use the platform for early warning interpretation and cannot run independently, that is, it cannot work offline. There are problems with untimely and delayed early warnings. In extreme cases, if the collection end cannot communicate normally with the platform, the early warning will be lost, which will cause the risk of monitoring loss. Summary of the invention

[0011] According to one aspect of the above technical solution, the distance between the first fixing mechanism and the second fixing mechanism is 50m-150m, and the distance between the second fixing mechanism and the third fixing mechanism is 250m-350m.

[0012] According to one aspect of the above technical solution, the alarm control module includes a first alarm controller MCU arranged on the second fixing mechanism, and a second alarm controller MCU arranged on the third fixing mechanism.

[0015] The present invention also provides a tunnel monitoring method, which is implemented by using the tunnel deformation monitoring and early warning system as described above, and comprises the following steps:

This design structure can realize local collection, local analysis and judgment, and local linkage, thereby improving the real-time performance and early warning function of the monitoring system. If the collected data is lower than the threshold, it proves that the distance of the monitored position in the tunnel meets the requirements, and the timing mechanism triggers the processing mechanism to sleep normally, waiting for the next time the timing mechanism wakes up the processing mechanism for collection. While collecting data through the laser rangefinder component, the collected data will be synchronously transmitted to the storage mechanism through the processing mechanism for storage, and the collected data will be synchronously transmitted to the external platform server through the communication component, so that the changes in data can be recorded through the storage mechanism, trends can be analyzed, and external staff can also be informed of the tunnel distance measurement situation, so as to make strategic responses according to the actual situation.

[0033] See also Figure 1 to Figure 2 , shown is a tunnel deformation monitoring and early warning system in the first embodiment of the present invention, including a first fixing mechanism, a monitoring mechanism arranged in the first fixing mechanism and the tunnel, an alarm device arranged in front of the first fixing mechanism, and a processing mechanism, a storage mechanism 4, a timing mechanism, and a transmission mechanism arranged on the first fixing mechanism, the monitoring mechanism includes a laser rangefinder component arranged on the first fixing mechanism, and a reflector component arranged in the tunnel, the transmission mechanism includes a communication component and a first LoRa transmission component 1 arranged on the first fixing mechanism, the laser rangefinder component is electrically connected to the processing mechanism, the processing mechanism is electrically connected to the storage mechanism 4, the timing mechanism, the communication component, and the first LoRa transmission component 1 respectively, the communication component is electrically connected to the external platform server, and the first LoRa transmission component 1 is electrically connected to the alarm device.

[0034] See also Figure 3 The tunnel detection method implemented by the above-mentioned tunnel deformation monitoring and early warning system includes the following steps:

[0035] S10, generating an alarm at irregular intervals according to the work granularity through the timing mechanism to wake up the processing mechanism to perform collection work;

[0036] S20, the processing mechanism starts the laser rangefinder assembly to emit laser toward the reflector assembly in the tunnel and collect data;

[0037] S30, using the threshold judgment module built into the processing mechanism to perform threshold judgment on the collected data, and if the collected data exceeds the threshold, the alarm device is linked to the alarm through the first LoRa transmission component for early warning linkage;

[0038] S40, if the collected data is lower than the threshold, the timing mechanism triggers the processing mechanism to perform normal sleep;

[0039] S50, synchronously transmitting the collected data to the storage mechanism for storage through the processing mechanism, and synchronously transmitting the collected data to the external platform server through the communication component.

[0040] It can be understood that the present invention sets a first fixing mechanism and an alarm device located in front of the first fixing mechanism, and sets a processing mechanism, a storage mechanism 4, a timing mechanism, and a transmission mechanism on the first fixing mechanism. Since the processing mechanism is electrically connected to the storage mechanism 4, the timing mechanism, the communication component, and the first LoRa transmission component 1 respectively, an alarm can be generated irregularly according to the working granularity through the timing mechanism to wake up the processing mechanism irregularly for collection work. When the processing mechanism is awakened, a laser is emitted toward the reflector assembly in the tunnel through the laser rangefinder assembly and data is collected. The collected data can be subjected to a threshold judgment through a threshold judgment module built into the processing mechanism. If the collected data exceeds the threshold, it proves that the distance of the monitored position in the tunnel does not meet the requirements, that is, through the first LoRa transmission Component 1 links the alarm device to perform early warning linkage. This design structure can realize local collection, local analysis and judgment, and local linkage, thereby improving the real-time performance and early warning function of the monitoring system. If the collected data is lower than the threshold, it proves that the distance of the monitored position in the tunnel meets the requirements, and the timing mechanism triggers the processing mechanism to sleep normally, waiting for the next time the timing mechanism wakes up the processing mechanism for collection. While collecting data through the laser rangefinder component, the collected data will be synchronously transmitted to the storage mechanism 4 for storage through the processing mechanism, and the collected data will be synchronously transmitted to the external platform server through the communication component, so that the changes in data can be recorded through the storage mechanism 4, trends can be analyzed, and external staff can also be informed of the tunnel distance measurement situation, so as to make strategic responses according to the actual situation.

[0041] The present invention can realize local collection, local analysis and judgment, and local linkage, thereby improving the real-time performance of the monitoring system and optimizing the early warning function.

[0042] Specifically, in this embodiment, the processing mechanism is the main control controller MCU2, the communication component is the 4G communication module 5, and the timing mechanism is the RTC clock module 6; the tunnel deformation monitoring and early warning system also includes a power supply mechanism 3 arranged on the first fixing mechanism, and the power supply mechanism 3 is used to supply power to each component on the first fixing mechanism.

[0043] It can be understood that the main controller MCU2 has excellent processing capabilities and can coordinate multiple electronic components to achieve stable operation of the system. The 4G communication module 5 has fast and efficient transmission capabilities, so that the collected data can be quickly transmitted to the external platform server, allowing the staff to understand the tunnel situation from a first-person perspective. The power supply mechanism 3 supplies power to all components on the first fixed mechanism.

[0044] Furthermore, the laser rangefinder assembly includes a first laser rangefinder 7 and a second laser rangefinder 8 arranged at the front end of the first fixing mechanism, the reflector assembly includes a first reflector 9 arranged at the tunnel vault and a second reflector 10 arranged at the side wall of the tunnel, the first laser rangefinder 7 emits laser toward the first reflector 9, and the second laser rangefinder 8 emits laser toward the second reflector 10.

[0045] It can be understood that the function of the first laser rangefinder 7 is to hit the laser on the first reflector 9 at the tunnel vault, so as to achieve the distance measurement at the tunnel vault. The function of the second laser rangefinder 8 is to hit the laser on the second reflector 10 at the tunnel side wall, so as to achieve the distance measurement at the tunnel side wall. The first laser rangefinder 7 and the second laser rangefinder 8 divide the work of distance measurement and transmit the data to the main controller MCU2 at the same time.

[0046] Furthermore, the alarm device includes a second fixing mechanism arranged in front of the first fixing mechanism, and a third fixing mechanism arranged in front of the second fixing mechanism, and the second fixing mechanism and the third fixing mechanism are both provided with an alarm control module, an information display module, a second LoRa transmission component, and an alarm response module; the alarm control module includes a first alarm controller MCU12 arranged on the second fixing mechanism, and a second alarm controller MCU16 arranged on the third fixing mechanism; the second LoRa transmission component includes a first LoRa transmitter 11 arranged on the second fixing mechanism, and a second LoRa transmitter 15 arranged on the third fixing mechanism, and the first LoRa transmitter 11 and the first alarm control The second LoRa transmitter 15 is electrically connected to the second alarm controller MCU16; the information display module includes a first LED information display board arranged at the front end of the second fixing mechanism, and a second LED information display board 17 arranged at the front end of the third fixing mechanism, the alarm response module includes a first sound and light alarm 14 arranged on the second fixing mechanism, and a second sound and light alarm 18 arranged on the third fixing mechanism, the first LED information display board 13 and the first sound and light alarm 14 are both electrically connected to the first alarm controller MCU12, and the second LED information display board 17 and the second sound and light alarm 18 are both electrically connected to the second alarm controller MCU16.

[0047] It can be understood that by arranging the second fixing mechanism and the third fixing mechanism in sequence in front of the first fixing mechanism, when the first laser rangefinder 7 detects that the distance at the tunnel vault is abnormal, or the second laser rangefinder 8 detects that the distance at the tunnel side wall is abnormal, the main controller MCU2 can link the first LoRa transmission component 1 to transmit the signal to the first LoRa transmitter 11 on the second fixing mechanism and the second LoRa transmitter 15 on the third fixing mechanism, and then respectively map the alarm information on the first LED information display board 13 and the second LED information display board 17 through the first alarm controller MCU12 and the second alarm controller MCU16, and broadcast the danger information through the first sound and light alarm 14 and the second sound and light alarm 18, so as to prompt the passing vehicles.

[0048] Preferably, the distance between the first fixing mechanism and the second fixing mechanism is 50m to 150m, and the distance between the second fixing mechanism and the third fixing mechanism is 250m to 350m. In this embodiment, the distance between the first fixing mechanism and the second fixing mechanism is 100m, and the distance between the second fixing mechanism and the third fixing mechanism is 200m to 300m.

[0049] It can be understood that by installing two sets of alarm devices in front of the first fixing mechanism, drivers and passengers in passing vehicles can be more certain of the danger ahead, and the distance is appropriate, giving drivers and passengers more reaction time.

[0050] It should be noted that the first fixing mechanism, the second fixing mechanism and the third fixing mechanism may be an integrated system fixedly arranged beside the rails.

[0051] In summary, the tunnel deformation monitoring and early warning system in the above embodiments of the present invention can realize local collection, local analysis and judgment, and local linkage, thereby improving the real-time performance of the monitoring system and optimizing the early warning function.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
