[0036] The electric telescopic rod 6 is driven by the controller 7, the controller 7 is wirelessly connected with the host computer 1, when a large amount of garbage accumulation is detected at a certain position of the pipeline, the host computer 1 predicts the fault point and the blockage condition, optimizes and adjusts the control strategy, and drives the controller 7 to open the movable baffle 8 closest to the blockage point through a wireless network, and when the gas flow rate reaches a set threshold value, the maintenance opening baffle is closed, and the load carrying capacity of the blockage point is greatly improved.

[0037] As Figure 2 shown, the vibration sensing system further comprises a protective sleeve 15 arranged along the outer wall of the garbage pneumatic pipeline 9, and the optical fiber sensor 10 is arranged in the protective sleeve 15.

Further preferably, the dredging and maintenance component is arranged in the turning area of the pipeline or the area prone to blockage.

[0040] The application also provides a garbage pneumatic pipeline dredging method based on the above garbage pneumatic pipeline dredging system, comprising the following steps:

[0041] Step 1: Real-time acquisition of vibration signals on the garbage pneumatic pipeline by the optical fiber sensor 10;

[0042] Step 2: The host computer 1 receives the vibration signals and analyzes the accumulation of garbage in the garbage pneumatic pipeline according to the vibration signals by using a deep learning algorithm;

[0043] Step 3: The host computer 1 judges according to the mapping threshold value and sends a control instruction to the controller 7 through a wireless network, and simultaneously alarms and prompts the fault point on the user interface; the mapping threshold value is a pre-set garbage accumulation amount;

[0044] Step 4: After receiving the control instruction, the controller 7 starts the electric telescopic rod and opens the corresponding movable baffle 8; when the gas flow reaches a predetermined value, the baffle is closed, and the pipeline is dredged by using the instantaneous pressure.

[0045] Specifically, when the controller 7 arranged on the site receives the instruction, the electric telescopic rod 6 is controlled to open the movable baffle 8 on the corresponding maintenance opening. When the gas flow in the garbage pneumatic pipeline 9 reaches a predetermined value, the movable baffle 8 is closed, and the pipeline is dredged by using the instantaneous pressure.

[0046] It needs to be further explained that: the existing garbage pneumatic conveying system can generally collect the dynamic pressure in the garbage pneumatic pipeline 9. If the dynamic pressure decreases significantly, it indicates that there is a blocked place in the pipeline. Open the access door baffle in front of the blocked point, and the airflow in the pipeline will flow, and the dynamic pressure will rise. When it rises to the set value, the baffle can be closed. The instantaneous pressure generated by closing the baffle is used to achieve the purpose of dredging the pipeline.

[0047] Further comprising the following steps:

[0048] Step 5, the laser 11 generates a laser beam, the photoelectric converter 3 converts the optical signal into an electrical signal, and then the data acquisition card 2 converts the electrical signal into a digital signal, and the digital signal is transmitted to the host computer 1 by wireless transmission. Specifically, one end of the optical fiber sensor 10 is provided with a laser 11, which is used to generate a laser beam as a light source of the sensor. The other end of the optical fiber sensor 10 is provided with a photoelectric converter and a data acquisition card. The photoelectric converter is used to convert the optical signal into an electrical signal, and then the data acquisition card converts the electrical signal into a digital signal, and the data is transmitted to the host computer by wireless transmission.

[0049] Step 6, the host computer 1 substitutes the digital signal into the deep learning model for analysis, and locates the garbage blockage position by the difference between the backscattering signals of the adjacent two periods, and obtains the blockage position; Specifically, the central control system installed in the host computer 1 substitutes the data into the deep learning model for analysis, and realizes accurate positioning of the garbage blockage position by analyzing the difference between the backscattering signals of the adjacent two periods.

[0050] Step 7, the host computer 1 sends a control instruction to the controller 7 through a wireless network to open the nearest movable baffle 8 from the blockage position. Specifically, after accurate positioning, the central control system sends a control instruction to the on-site controller through a wireless network to open the movable baffle 8 on the access door closest to the blockage point.

[0051] Further comprising the following steps:

[0052] Step 8, after the movable baffle 8 is closed for 2-4 seconds, the optical fiber sensor continues to detect the garbage state. If it is detected that there is still a large amount of garbage accumulation, the host computer 1 opens the movable baffle 8 again to change the gas flow rate in the pipeline, and uses the instantaneous pressure to dredge the pipeline again to realize higher blockage point carrying capacity.

[0053] The application also provides a garbage pneumatic pipeline dredging method, which helps the operator to judge whether there is a large amount of garbage accumulation in the pipeline and automatically dredges after locating the blockage point; realizes timely discovery and early warning of the blockage in the pipeline, so that the staff does not need to blindly find the blockage position when the pipeline is blocked, and the blockage point can be accurately found through the positioning technology of the sensor, greatly improving the safety and reliability of the garbage pipeline; realizes the automatic dredging function, and when the system is conveying garbage, if a large amount of garbage accumulation occurs, the staff does not need to operate, and the system will timely dredge, greatly improving the work efficiency.

[0054] The above merely describes the preferred embodiments of the application and is not intended to limit the application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
