The slope seat 32 is tilted to facilitate the automatic trolley 3 to move to the base station seat 2. A sealing cover 34 located outside the base station seat 2 and in contact with the base station seat 2 is installed and fixed at the push rod of the electric push rod 33.

[0083] When the push rod of the second electric push rod 33 is in a fully retracted state, the two sealing covers 34 are in contact with each other and closely fit with the outside of the buffer outer cover 22;

[0084] The outer side of the sealing cover 34 is bonded with sealing rubber to improve the sealing effect when the sealing cover 34 is combined and prevent the entry of rainwater.

[0085] To sum up, the usage of this environmental gas monitor is:

[0086] 1. When in use, each base station seat 2 is installed and fixed at each monitoring point by tightening screws. After that, when monitoring is carried out, the automatic trolley 3 is located on the base station seat 2, and the sealing cover 34 is driven to move and fit closely with the buffer outer cover 22 by starting the electric push rod 23 (thereby, the sealing cover 34 locks and fixes the buffer outer cover 22, and the automatic trolley 3 is locked and fixed on the base station seat 2. At the same time, the sealing cover 34, the base station seat 2 and the buffer outer cover 22 form a closed space to protect the automatic trolley 3 and prevent the automatic trolley 3 from being affected by the external environment);

[0087] 2. After the automatic trolley 3 is locked and fixed on the base station seat 2, the air pump 7 is started to work and the air pump 7, the air pipe 8, the connecting pipe 6 and the telescopic rod 5 are connected to each other (at this time, the exhaust valve 9 is in a closed state, and the gear block 20 and the rack 15 are in a separated state), so that gas is filled into the telescopic rod 5, and the telescopic rod 5 is pushed to fully extend under the action of atmospheric pressure. After the telescopic rod 5 is fully extended, the electromagnet 13 is started to work to adsorb and fix the connection nodes of each hollow sleeve after extension, so as to achieve the locking and fixation of the telescopic rod 5 after extension, and then realize the meteorological environment monitoring after the monitoring box 1 is unfolded;

[0088] Third, after the monitoring of this fixed point is completed, the electromagnet 13 is powered off and the exhaust valve 9 is opened. Under the gravity of the monitoring machine case 1, the telescopic rod 5 is compressed and contracted to discharge the gas. At the same time, as the telescopic rod 5 contracts, the monitoring machine case 1 moves down synchronously, so that when the monitoring machine case 1 moves down to the bottom, the buffer seat 14 contacts the buffer rubber block 21 to buffer the impact force, so as to avoid the monitoring machine case 1 from falling and being damaged. After the monitoring machine case 1 is completed, the electric push rod 16 is set to work. During the process of the electric push rod 16 pushing the movable seat 17 to move upward, the rotating connection between the rotating rod 18 and the movable seat 17 and the tooth block 20 is utilized, and the linear limiting movement of the tooth block 20 by the guide limit seat 19 is used, so that when the movable seat 17 moves upward, the tooth block 20 is pushed to move and mesh with the rack 15, thereby realizing the locking and fixing of the monitoring machine case 1;

[0089] Third, after the monitoring machine chassis 1 is folded and locked, the electric push rod 2 33 is started to drive the sealing cover 34 to move in the opposite direction and unfold. At the same time, the automatic trolley 3 is started to move through the ramp seat 32 to move away from the base station seat 2 to the ground. At this time, the forward threaded rod 27 and the reverse threaded rod 28 are driven to rotate by the dual-axis output motor 26. The threaded connection between the forward threaded rod 27 and the reverse threaded rod 28 and the threaded moving frame 29 is utilized, and the automatic trolley 3 moves the threaded moving frame 29 in a linear limit manner, so that the forward threaded rod 27 and the reverse threaded rod 28 rotate, and the two threaded moving frames 29 are driven to move and unfold. , and simultaneously drive the auxiliary stabilizing wheels 30 to unfold and support on the ground for auxiliary support rolling, so as to ensure that after the monitoring machine chassis 1 is shrunk and fixed, the auxiliary stabilizing wheels 30 are unfolded and rolled, so as to improve the stability of the overall movement on the ground, and then facilitate the automatic trolley 3 to drive the entire equipment to move to the base station seat 2 of the next monitoring point in a stable moving state. At the same time, during the movement of the automatic trolley 3, the shock-absorbing ball 25 is in the space composed of the outer annular groove 24 and the inner annular groove 23 between the base 4 and the buffer cover 22, so as to reduce the amplitude of the movement, avoid the overall monitoring machine chassis 1 from shaking significantly during the movement, and further improve the stability of the movement;

[0090] Finally, when the automatic trolley 3 moves to the next base station seat 2, the dual-axis output motor 26 is started to drive the forward threaded rod 27 and the reverse threaded rod 28 to rotate in the opposite direction, so that the auxiliary stabilizing wheel 30 is retracted, and the automatic trolley 3 drives to the next base station seat 2, repeats steps one and two, and monitors the next monitoring point, thereby realizing mobile multi-point monitoring, improving the comprehensive accuracy of data monitoring, and avoiding the defect of high maintenance cost of multiple fixed-point monitoring.

[0091] This application is based on the automatic line of the automatic car 3 moving to each fixed base station seat 2, there is the following system,

[0092] 1 Line Modeling

[0096] Camera: used for image processing and line recognition.

[0097] LiDAR: used for environment modeling and obstacle detection.

[0098] Infrared sensors, cameras and laser radar are all installed on the automatic car 3

[0099] 2. Path Planning

[0100] Path planning algorithm: According to the line model, a path planning algorithm (such as A* algorithm, Dijkstra algorithm, etc.) is used to generate the motion path of the small automatic car 3.

[0101] Coordinate system: A coordinate system is established according to the specific positions of each base station 2 to facilitate the positioning and navigation of the automatic vehicle 3 on the path.

[0102] 3. Motion Control

[0103] Motion model: A motion model is established according to the motion characteristics of the automatic car 3 (such as speed, acceleration, turning radius, etc.).

[0104] Control algorithm: Implement control algorithms (such as PID control, fuzzy control, etc.) to ensure that the automatic car 3 moves smoothly along the planned path.

[0105] Motor control: The motor drives the automatic car 3 to move forward, turn and stop.

[0106] 4. Fixed-point parking

[0107] Parking position identification: an identification (such as a mark of a specific color, a QR code, etc.) is set at the target parking position so that the automatic car 3 can identify it.

[0108] Precise positioning: Use sensors (such as ultrasonic sensors, laser sensors, etc.) to measure distances to ensure that the automatic car 3 can accurately reach the parking position.

[0109] Parking control: When approaching the parking position, the vehicle gradually decelerates until the automatic vehicle 3 completely stops at the designated position.

[0110] The identification structure is arranged on the base station seat 2 .

[0111] 5. Feedback and Adjustment

[0112] Real-time feedback: The position and state of the automatic car 3 are monitored in real time through sensors, and dynamic adjustments are made.

[0113] Error correction: If the automatic car 3 deviates from the predetermined path, the control system should be able to automatically adjust the direction to get back on track.

[0114] 6. Testing and Optimization

[0115] Test: Test the performance of the automatic car 3 in a real environment and observe its effect of moving along the line and parking at a fixed point.

[0116] Optimization: Based on the test results, adjust the control parameters and algorithms to improve the stability and accuracy of the automatic car 3.

[0117] 7. Software Implementation

[0118] Programming: Use a suitable programming language (such as C++, Python, etc.) to write control programs that integrate functions such as sensor data processing, path planning, and motion control.

[0119] Debugging: Perform debugging during actual operation to ensure the reliability and response speed of the system.

[0120] The above system controls are all direct applications of existing technologies.

[0121] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
