Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to an intelligent control system for fog cannons. Background Technology

[0002] Currently, traditional fog cannon equipment mostly relies on manual operation or single sensor control, making it difficult to achieve intelligent and precise dust suppression. Existing systems generally suffer from simple control logic and weak multi-device coordination capabilities. For example, they cannot automatically adjust spray parameters when dust concentration exceeds the standard, require manual switching of operating modes under different working conditions, and lack efficient data exchange mechanisms between devices, resulting in low dust suppression efficiency and high energy consumption.

[0003] Furthermore, existing fog cannon equipment suffers from insufficient adjustment precision in its mechanical structure. For example, traditional gimbals use open-loop control, which cannot provide real-time feedback on the spray angle, resulting in significant deviations in the water mist coverage area. High-pressure atomization systems lack closed-loop pressure regulation, making it difficult to adapt to different water qualities and environmental conditions. Additionally, existing equipment generally lacks integrated disinfection functions, failing to meet the hygiene and epidemic prevention needs of special scenarios. Utility Model Content

[0019] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0021] like Figure 1 As shown, the present invention proposes an intelligent control system for fog cannons, which mainly consists of a control unit 1, a communication hub 5, a data acquisition module 2, an execution module 3, and an auxiliary module 4.

[0022] The control unit 1 has a built-in RS485 communication module 101 and a multi-channel I / O interface 102. The RS485 communication module 101 is used to communicate with the communication hub 5 and exchange data through the MODBUS RTU protocol. The multi-channel I / O interface 102 is used to connect various sensors and actuators in the system to control them and acquire data.

[0023] The communication hub 5 serves as the communication center between the various modules of the system. It connects to the RS485 communication module 101 of the control unit 1 via the MODBUS RTU protocol. Simultaneously, it also communicates bidirectionally with the data acquisition module 2, execution module 3, and auxiliary module 4 via RS485 branch lines 601, 602, and 603, respectively, enabling data transmission and command delivery between the modules.

[0024] Data acquisition module 2 includes a dust concentration sensor 201, a multi-parameter meteorological sensor 202, a high-definition camera 203, and an angle encoder 204. These sensors and devices collect environmental data in real time, such as dust concentration, meteorological parameters, images of the work area, and the rotation angle of the servo pan-tilt unit 302. The collected data is transmitted to the communication hub 5 via an RS485 branch line 601, and then transmitted by the communication hub 5 to the control unit 1 for processing. Specifically, the dust concentration sensor 201 and the multi-parameter meteorological sensor 202 are connected to the analog input module of the control unit 1 via signal cables, and the high-definition camera 203 is connected to the image acquisition module of the control unit 1 via a video signal line.

[0025] The execution module 3 includes a high-pressure atomizing device 301, a servo gimbal 302, and a centrifugal fan 303. The control unit 1 sends control commands to the execution module 3 via a multi-channel I / O interface 102 based on data from the data acquisition module 2. The water inlet of the high-pressure atomizing device 301 is connected to the solenoid valve group 403 of the auxiliary module 4 via a pipe to obtain a water source. The air outlet of the centrifugal fan 303 is coaxially arranged with the spray channel of the high-pressure atomizing device 301, providing power for the spray and enabling the water mist to be sprayed further. The rotation axis of the servo gimbal 302 is mechanically connected to the spray head of the high-pressure atomizing device 301, enabling horizontal rotation and pitch adjustment of the spray head. An angle encoder 204 is installed at the rotation joint of the servo gimbal 302, providing real-time feedback on the rotation angle of the servo gimbal 302, forming a closed-loop control with the control unit 1 to ensure the accuracy of the spray direction. Meanwhile, the multi-channel I / O interface 102 of the control unit 1 is also electrically connected to the limit switch group of the servo gimbal 302, the pressure sensor of the high-pressure atomizing device 301, and the frequency converter of the centrifugal fan 303, respectively, to monitor and control the status of these devices.

[0026] Auxiliary module 4 includes a hypochlorous acid generator 401, a level sensor 402, and a solenoid valve assembly 403. The output of the hypochlorous acid generator 401 is connected to the mixing interface of the solenoid valve assembly 403 via a pipe, allowing the hypochlorous acid solution to be mixed with water for disinfection or other functions as needed. The level sensor 402 monitors the water level in the tank and is connected to the digital input module of the control unit 1 via a signal line. When the water level is too low or too high, it sends a signal to the control unit 1, enabling the control unit 1 to take appropriate measures, such as stopping the operation of the high-pressure atomizing device 301 or issuing an alarm. The solenoid valve assembly 403 controls the flow of water and the mixing ratio of the hypochlorous acid solution according to the instructions of the control unit 1.

[0027] When the system is powered on, the control unit 1 first performs a self-test and establishes communication connections with each module through the communication hub (5) to complete the initial configuration. The data acquisition module 2 starts to monitor the data of the dust concentration sensor 201, the multi-parameter meteorological sensor 202, the high-definition camera 203 and the angle encoder 204 in real time, and transmits it to the control unit 1 for fuzzy algorithm analysis through the RS485 branch line 601. The control unit 1 generates control commands based on the data and drives the execution module 3 to adjust the spray parameters: the high-pressure atomizing device 301 achieves pressure regulation through the plunger pump and the venturi nozzle group, the centrifugal fan 303 achieves speed control through the frequency converter, the servo gimbal 302 achieves precise positioning through the horizontal rotation mechanism and the pitch adjustment mechanism, and the angle encoder 204 provides real-time feedback to form a closed-loop control. The hypochlorous acid generator 401 in the auxiliary module 4 dynamically mixes disinfectant with the atomizing system through the solenoid valve group 403, and the liquid level sensor 402 monitors the water tank status and triggers the protection mechanism. The system supports MQTT protocol and cloud communication to realize remote status monitoring, parameter adjustment and fault diagnosis. When the operation is completed, control unit 1 shuts down the actuators in sequence and terminates data acquisition, thus completing the system shutdown process.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
