During the transportation of these dangerous goods, it is very important to ensure the safety of the transport vehicles, among which the safety of the vehicle chassis is the top priority. However, there are many problems in the chassis inspection and maintenance of existing dangerous goods transport vehicle inspection stations. The traditional inspection stations have the following technical problems in the inspection of vehicle chassis:

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. A complete set of integrated control systems for dangerous goods transport vehicles is constructed in the present invention. The hardware and software parts of the inspection station work closely together to form a highly integrated and collaborative control system. Through standardized data interfaces and communication protocols, data can be transmitted and processed in real time and accurately between the various parts. From information collection and verification when the vehicle enters the inspection station, to comprehensive inspection and data processing analysis in the inspection area, to monitoring and management in the detention area, and overall coordination in the office area, all-round coverage of inspection and management of dangerous goods transport vehicles is achieved. This comprehensive, accurate and efficient service model not only improves the work quality and efficiency of the inspection station, but also provides a strong guarantee for the safety of dangerous goods transportation. Through remote control of the chassis monitoring mechanism, the chassis of the transport vehicle can be quickly scanned and photographed. There is no need for the inspectors to observe the bottom of the vehicle with the naked eye for a long time, which greatly shortens the inspection time. The cooperation of the camera and the lighting can quickly obtain a comprehensive and clear chassis image, upload it to the high-definition display screen for staff to observe and back up, so as to quickly complete the preliminary inspection and significantly improve the overall work efficiency of the inspection station.

[0020] 2. Reduce the frequency of inspectors entering the bottom of the vehicle, greatly reducing potential safety risks. The remote operation and image transmission function of the chassis monitoring mechanism eliminates the need for inspectors to be in the small and dangerous space under the vehicle chassis. This effectively avoids casualties that may be caused by accidental vehicle movement, falling chassis parts, etc., and provides more reliable protection for the life safety of inspectors.

[0021] 3. Inspectors can judge the chassis condition based on the clear, comprehensive and accurate images taken by the chassis monitoring mechanism. These high-definition images can clearly show the details of chassis damage, cracks, etc., allowing inspectors to make more accurate judgments and avoid misjudgments caused by incomplete or unclear observations. This ensures that only vehicles with real safety hazards are deemed unqualified, improving the accuracy and reliability of the inspection.

[0022] 4. When the camera on the mobile seat captures a chassis problem that needs further confirmation, it will stay at the location of the problem. This allows maintenance personnel to quickly reach the problem point after entering the maintenance tunnel, without spending time looking for it, and can directly carry out maintenance work. This precise positioning function significantly reduces the time and energy spent by maintenance personnel in finding problems, greatly improving the efficiency of maintenance work.

[0023] 5. The chassis monitoring mechanism has excellent flexibility and adjustability, and can meet the needs of a variety of complex maintenance scenarios. When a higher position needs to be inspected, the mechanism can be tilted or extended to act as a ladder, making it convenient for maintenance personnel to climb to the appropriate height. For locations at different heights and difficult to reach, such as the connection between the transport compartment and the front of the vehicle, the inclination, length and height of the ladder can be flexibly adjusted to ensure that maintenance personnel can safely and conveniently reach the designated location for maintenance work.

[0024] 6. When there are multiple problem points on the chassis, maintenance personnel can hang the chassis monitoring mechanism on the side of the maintenance tunnel. This will free up walking space in the tunnel for other maintenance personnel and will not hinder their maintenance work. This allows multiple maintenance personnel to perform maintenance operations without interfering with each other at the same time, greatly improving the progress and efficiency of the overall maintenance work.

[0025] 7. A wireless charging power source is installed in the mobile base. After the chassis monitoring mechanism completes its work and resets, the wireless charging panel on the maintenance tunnel can charge its power source. This design ensures that the chassis monitoring mechanism is always in a standby state with sufficient power and can be put into the next inspection or maintenance task at any time, avoiding the situation where the equipment cannot operate normally due to insufficient power, and improving the availability and reliability of the equipment.

DETAILED DESCRIPTION

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] See also Figure 1-Figure 8 The present invention provides an integrated inspection station for dangerous goods transport vehicles, including a hardware part and a software part. The hardware part includes an import and export gate module, a detection area site, a detention area site, an office area site, a data transmission line, and a monitoring device. The software part includes a central control software, a data acquisition and analysis software, a monitoring and tracking software, and a database management software. The hardware part and the software part are connected through a standardized data interface and a communication protocol to form an integrated control system for dangerous goods transport vehicles. The import and export gate module includes a vehicle identification component, a gate drive component, a control unit, a communication module, a sensor component, a power supply module, a display and indication component, and a mechanical structure component. The detention area site includes a detention area foundation, a vehicle fixing device, and a site monitoring device. An office space is built on the office area site, and an operation terminal and a high-definition display screen are set in the office space. The data transmission line adopts a hybrid transmission technology of wired and wireless.

[0037] When a dangerous goods transport vehicle drives towards the inspection station, the import and export gate module starts working first. The license plate recognition camera and RFID reader in the vehicle identification component quickly read the vehicle's license plate information and pre-installed electronic tags, while the infrared vehicle detector senses the arrival of the vehicle. This information is transmitted to the control unit, which communicates with the central control software through the communication module to verify the legality of the vehicle and the scheduled inspection information. If the vehicle is legal, the control unit drives the gate drive component to raise the gate, and the display and indication component displays a signal that allows passage.

[0038] The inspection area, which consists of the inspection area foundation 1 and the inspection area light steel structure canopy 2, is equipped with high-definition imaging inspection equipment, gas composition analysis equipment, and vehicle structure flaw detection equipment. After the vehicle enters the inspection area, the inspection work is fully launched. The high-definition imaging inspection equipment in the inspection area performs a full-scale scan of the vehicle's appearance to capture subtle damage and abnormalities. The gas composition analysis equipment collects gas samples around the vehicle to analyze whether there is a dangerous gas leak. The vehicle structure flaw detection equipment uses ultrasonic or other non-destructive testing technology to check the integrity of the vehicle structure. The data collected by these devices are quickly and stably transmitted to the data acquisition and analysis software through a mixed wired and wireless data transmission line.

[0039] The data acquisition and analysis software uses data analysis algorithms and pre-trained models to perform real-time processing and intelligent analysis of massive detection data. It can quickly identify potential safety hazards and immediately feed back the analysis results to the central control software. Among them, the data analysis algorithm uses a convolutional neural network (CNN) algorithm based on deep learning for the analysis of image data, such as vehicle appearance images obtained from high-definition imaging detection equipment. Through multi-layer convolution and pooling operations, features in the image, such as the shape, location and degree of damage, are automatically extracted. For the data collected by the gas composition analysis equipment, principal component analysis (PCA) and cluster analysis algorithms are used. PCA is used to reduce the data dimension and extract the main components, and cluster analysis is used to classify the gas composition data to determine whether there is an abnormal combination of gas components, indicating potential leakage risks; in terms of pre-trained models, for the damage detection of vehicle appearance, a convolutional neural network model is trained using a vehicle image data set labeled with various types and degrees of damage. The model learns the characteristic patterns of different damages and can quickly and accurately identify the damage in the new input image. For the analysis of gas composition, a classification model based on historical gas composition data and corresponding safety / hazard labels is pre-trained. This model can determine whether the newly collected gas composition data is within a safe range. In terms of vehicle structure flaw detection, a model trained based on flaw detection signal samples of known structural defects is established. This model can determine whether there are hidden dangers in the vehicle structure based on new flaw detection signals.

[0040] The monitoring equipment monitors the situation in the detection area and the detention area throughout the process. The video images captured by the high-definition camera are transmitted to the monitoring and tracking software through the data transmission line. The monitoring and tracking software uses image recognition technology and positioning algorithms to track the location and status of the vehicle in real time. Once abnormal behavior or situation is found, an alarm will be immediately issued and relevant information will be recorded.

[0041] In the detention area, vehicle fixing devices ensure the stable parking of detained vehicles, and site monitoring equipment closely monitors the status of vehicles. Monitoring data is also transmitted to monitoring and tracking software to achieve comprehensive supervision.

[0042] In the office area, staff can obtain detailed information about each area of ​​the testing station in real time through operating terminals and high-definition display screens. As the core of the entire system, the central control software coordinates and controls the operation of each hardware part based on the results of the data acquisition and analysis software, the feedback of the monitoring and tracking software, and the preset workflow and rules.

[0043] The database management software is responsible for safely and efficiently storing all inspection data, vehicle information, and system operation history. Through standardized data interfaces and communication protocols, the hardware and software parts work closely together to form a highly integrated and coordinated integrated control system for dangerous goods transport vehicles, providing comprehensive, accurate, and efficient services for the inspection and management of dangerous goods transport vehicles.

[0044] The detection area site includes a detection area foundation 1 and a detection area light steel structure canopy 2. Two maintenance tunnels 11 are dug on the ground of the detection area foundation 1. A bottom monitoring mechanism is installed in each maintenance tunnel 11. The bottom monitoring mechanism includes a moving seat 13 and a sliding seat 12. The front end of each maintenance tunnel 11 is a slope, and a wireless charging panel 8 is installed at the rear end of each maintenance tunnel 11. Pulley grooves 5 are opened at the upper ends of the inner walls on both sides of each maintenance tunnel 11, and a disengagement groove 7 is opened at the rear end of each pulley groove 5. A pulley clamping strip 6 is fixed to the bottom of each pulley groove 5. A strip groove 10 and a group of equidistant slots 9 are opened at the lower ends of the inner walls on both sides of each maintenance tunnel 11. Four groups of clamping slots 4 are opened on the ground of the detection area foundation 1;

[0045] A full-angle monitoring device is installed on the light steel structure canopy 2 in the detection area. When the monitoring device installed on the light steel structure canopy 2 in the detection area recognizes that the vehicle enters the site and stops, the double-end output shaft controllable synchronous motor in the mobile seat 13 is remotely controlled to start, and the two output shafts of the double-end output shaft controllable synchronous motor rotate, and the entire bottom monitoring mechanism is driven to move along the pulley card strip 6 through the roller 17. The monitoring component on the mobile seat 13 includes two lighting lamps and a steerable camera. During the movement, the camera on the mobile seat 13 cooperates with the lighting lamp to scan and shoot the chassis of the transport vehicle, and uploads it to the high-definition display screen for staff to observe and back up. The preliminary inspection does not require the operator to enter the bottom of the vehicle for naked eye observation, and the chassis of the transport vehicle can be quickly and remotely detected, thereby improving the detection efficiency and reducing the frequency of detection personnel entering the chassis of the transport vehicle, thereby improving safety. The chassis image captured by the camera is clear and comprehensive, which is also helpful for later viewing and comparison;

[0046] The moving seat 13 is equipped with a double-end output shaft controllable synchronous motor and a power supply. The two output shafts of the double-end output shaft controllable synchronous motor pass through the two ends of the moving seat 13 respectively and rollers 17 are fixed at the ends. The wheel surface of each roller 17 is provided with an annular groove 16, wherein two connecting seats 22 are fixedly connected to the bottom surface of the moving seat 13, and an equidistant pedal 20 is fixed between the two connecting seats 22. The opposite surfaces of the two moving seats 13 are fixedly connected with L-shaped limit plates 3, and each limit plate 3 is provided with a group of circular holes 18. The second pedal 20 from the bottom to the top is penetrated by a rod groove 23, and the two ends of the rod groove 23 pass through the two connecting seats 22 respectively. Two limit rods 26 are movably sleeved in the rod groove 23, and a spring 26 is fixedly connected between the two limit rods 26. 7. The bottom surface of the second pedal 20 from bottom to top is provided with a strip-shaped bottom groove 25, and the adjacent ends of the two limit rods 26 are fixedly connected with the lever 32, and the lever 32 is stuck in the bottom groove 25, wherein the bottom surfaces of the two limit plates 3 are fixedly connected with the bottom plate 21, and during the movement of the moving seat 13, the ends of the two limit rods 26 are stuck in the strip groove 10, and the groove wall of the strip groove 10 does not contact the limit rod 26, and does not affect the movement of the moving seat 13. When the image taken by the camera on the moving seat 13 shows that the chassis of the transport vehicle is damaged, cracked, or other conditions that are not conducive to safe transportation, the inspection personnel can directly declare the inspection unqualified or arrange for maintenance personnel to enter the chassis of the transport vehicle for further confirmation based on the situation displayed in the image, so as to avoid misjudgment and improve the inspection effect;

[0047] Two side hanging plates 14 are also fixed on the moving seat 13, and the bottom surface of each side hanging plate 14 is fixedly connected with a hanging tooth 15. When the hanging tooth 15 is engaged with the slot 4 at the corresponding position, the moving seat 13 and the connecting seat 22 are both in contact with the inner wall of the maintenance tunnel 11. Vertical long grooves 19 are penetrated on both sides of the frame body composed of the moving seat 13 and the connecting seat 22. Connecting frames 35 are fixedly connected on both sides of the bottom of the sliding seat 12. A pair of connecting pieces 28 are fixedly connected to the top surface of the sliding seat 12. Vertical long rods 29 are fixedly connected to the two connecting pieces 28. The two long rods 29 are movably sleeved with the two long slots 19 respectively. An equidistant pedal 2 36 is fixedly connected between the two connecting frames 35. A bottom groove 2 33 is opened on the bottom surface of the bottom pedal 2 36. A horizontal rod groove 2 30 is penetrated by the bottom pedal 2 36. The two ends of the rod groove 2 30 penetrate the two connecting frames 35 respectively. There are two limit rods 31, and a spring 34 is fixedly connected between the two limit rods 31. The proximal ends of the two limit rods 31 are fixedly connected with the same lever 32. The lever 32 on the limit rod 31 is stuck in the bottom groove 33, wherein the separated ends of the two limit rods 31 are respectively stuck in the circular holes 18 on the two limit plates 3, the moving seat 13 and the sliding seat 12 are fitted, and the two connecting seats 22 are respectively fitted with the two connecting frames 35. The disengagement groove 7 is used to take the chassis monitoring mechanism out of the maintenance tunnel 11. When the chassis monitoring mechanism completes the work, the remote control moving seat 13 is reset. A wirelessly rechargeable power supply is installed in the moving seat 13. The power supply provides power for the camera, the lighting and the communication components. After the moving seat 13 is reset, the wireless charging panel 8 installed on the maintenance tunnel 11 is close to the power supply in the moving seat 13 for charging, so that the chassis monitoring mechanism is always in standby state.

[0048] Working principle: When a dangerous goods transport vehicle drives towards the inspection station, the import and export gate module starts working first. The license plate recognition camera and RFID reader in the vehicle identification component quickly read the vehicle's license plate information and the pre-installed electronic tag. At the same time, the infrared vehicle detector senses the arrival of the vehicle. This information is transmitted to the control unit. The control unit communicates with the central control software through the communication module to verify the legality of the vehicle and the scheduled inspection information. If the vehicle is legal, the control unit drives the gate drive component to raise the gate, and the display and indication component displays a signal allowing passage;

[0049] After the vehicle enters the inspection area, the inspection work is fully launched. The data collected by each inspection equipment is quickly and stably transmitted to the data acquisition and analysis software through a mixed wired and wireless data transmission line. The data acquisition and analysis software uses data analysis algorithms and pre-trained models to process and intelligently analyze massive inspection data in real time, quickly identify potential safety hazards, and immediately feed back the analysis results to the central control software. The monitoring equipment monitors the inspection area and the detention area throughout the process. The video images taken by the high-definition camera are transmitted to the monitoring and tracking software through the data transmission line. The monitoring and tracking software uses image recognition technology and positioning algorithms to track the location and status of the vehicle in real time. Once abnormal behavior or situation is found, an alarm is immediately issued and relevant information is recorded;

[0050] In the detention area, vehicle fixing devices ensure the stable parking of detained vehicles, and on-site monitoring equipment closely monitors the status of vehicles. The monitoring data is also transmitted to the monitoring and tracking software to achieve comprehensive supervision;

[0051] In the office area, staff can obtain detailed information of each area of ​​the testing station in real time through operating terminals and high-definition display screens. The central control software, as the core of the entire system, coordinates and controls the operation of each hardware part based on the results of the data acquisition and analysis software, the feedback of the monitoring and tracking software, and the preset workflows and rules;

[0052] The database management software is responsible for safely and efficiently storing all inspection data, vehicle information and system operation history records. Through standardized data interfaces and communication protocols, the hardware and software parts work closely together to form a highly integrated and coordinated integrated control system for dangerous goods transport vehicles, providing comprehensive, accurate and efficient services for the inspection and management of dangerous goods transport vehicles.

[0053] When the monitoring equipment installed on the light steel structure canopy 2 in the detection area recognizes that the vehicle enters the site and stops, the double-end output shaft controllable synchronous motor in the remote-controlled mobile seat 13 is started, and the two output shafts of the double-end output shaft controllable synchronous motor rotate, and the entire bottom monitoring mechanism is driven to move along the pulley card strip 6 through the roller 17. The monitoring component on the mobile seat 13 includes two lighting lamps and a steerable camera. During the movement, the camera on the mobile seat 13 cooperates with the lighting lamp to scan and shoot the situation of the chassis of the transport vehicle, and uploads it to the high-definition display screen for staff to observe and back up. The preliminary inspection does not require the operator to enter the bottom of the vehicle for naked eye observation, and the situation of the chassis of the transport vehicle can be quickly and remotely detected, thereby improving the detection efficiency and reducing the frequency of detection personnel entering the chassis of the transport vehicle, thereby improving safety. The chassis image captured by the camera is clear and comprehensive, which is also helpful for later viewing and comparison;

[0054] During the movement of the moving seat 13, the ends of the two limit rods 26 are stuck in the strip groove 10, and the groove wall of the strip groove 10 does not contact the limit rod 26, which does not affect the movement of the moving seat 13. When the image taken by the camera on the moving seat 13 shows that the chassis of the transport vehicle is damaged or cracked, which is not conducive to safe transportation, the inspection personnel can directly declare the inspection unqualified or arrange maintenance personnel to enter the chassis of the transport vehicle for further confirmation based on the situation displayed in the image, so as to avoid misjudgment and improve the inspection effect;

[0055] When the mobile seat 13 captures a chassis problem that needs further confirmation, it will stay at the problem location. After the maintenance personnel enter the maintenance tunnel 11, they can quickly reach the problem location, which reduces the time for finding the problem location and improves work efficiency.

[0056] After the maintenance personnel arrive at the problem point, according to the problem point and the height of the chassis of the transport vehicle, if the maintenance personnel can directly inspect and repair in the maintenance tunnel 11, the movable seat 13 can be reset. If the maintenance personnel cannot directly contact the problem point in the maintenance tunnel 11, they can pull the lever 32 on the limit rod 1 26 to make the two limit rods 1 26 disengage from the strip groove 10, and then deflect the entire chassis monitoring mechanism clockwise so that the limit rod 1 26 can be inserted into the nearest slot 9. At this time, the entire chassis monitoring mechanism is in an inclined state and acts as a ladder. The chassis monitoring mechanism is not easy to deviate. The maintenance personnel can climb up with the help of the pedals on the chassis monitoring mechanism, so that they can contact the problem point for maintenance;

[0057] If the chassis monitoring mechanism is in a tilted state and acts as a ladder, it still cannot reach the height of the problem point, such as the connection area between the transport carriage and the front of the vehicle. There is enough space for operation, but because the connection point is located in the middle part, it is not easy to enter from both sides of the transport vehicle. At this time, the lever 32 on the two limit rods 31 can be moved to make the two limit rods 31 disengage from the circular hole 18. At this time, the connecting frame 35 loses the restriction and can slide upward, and maintains the same direction with the connecting seat 22 under the restriction of the limit plate 3. According to the location of the problem point, a certain height is extended so that the limit rod 31 is aligned with the nearest circular hole 18 and inserted, and the position of the connecting frame 35 can be fixed, so as to achieve the effect of extending the height of the ladder, further improving the scope of application of the chassis monitoring mechanism for maintenance, and the extended ladder, the limit rod 31 is inserted into the circular hole 18 to provide longitudinal limitation, and the long rod 29 slides in the long groove 19 to provide lateral limitation, providing multiple force points, so as to achieve the effect of maintaining the stability of the extended ladder;

[0058] When the chassis of the transport vehicle needs to be repaired and parts are inspected, the commonly used method is that the maintenance personnel carry out maintenance in the middle position of the chassis in the maintenance tunnel 11, and on the ground, the maintenance personnel lie down under the chassis to inspect both sides of the chassis, and cancel the limit by toggling the lever 32 on the limit rod 26, and deflect the chassis monitoring mechanism until the end of the limit rod 26 can be stuck in the pulley groove 5 and supported by the pulley clamping strip 6. At this time, the chassis monitoring mechanism is in a nearly horizontal state, and the height difference with the ground is very small. The personnel who are repairing the chassis of the transport vehicle can adjust the chassis monitoring mechanism to a horizontal state. Through the two sides of the maintenance tunnel 11, the maintenance personnel can smoothly move from one side of the chassis to the other side when performing maintenance under the chassis, avoiding the maintenance personnel having to climb out of the chassis after completing maintenance on the left side of the chassis, walk to the other side of the chassis, and then enter under the chassis to perform maintenance on the other side. It can also help the maintenance personnel to directly lie on the chassis monitoring mechanism to perform maintenance at the middle position of the chassis after completing maintenance on both sides of the chassis, without having to climb out of the chassis and then enter the maintenance tunnel 11 to perform maintenance at the middle position of the chassis, thereby improving convenience and maintenance efficiency, reducing the frequency of maintenance personnel entering and exiting the chassis, and also helping to reduce safety risks;

[0059] If there are multiple problem points, after entering the maintenance tunnel 11, the maintenance personnel can move the chassis monitoring mechanism upward to disengage the annular groove 16 on the roller 17 from the pulley clamping strip 6, and then horizontally deflect the chassis monitoring mechanism, and according to the situation, the chassis monitoring mechanism is engaged with the clamping groove 4 through the hanging teeth 15, so that the chassis monitoring mechanism is hung on the side of the maintenance tunnel 11. The maintenance personnel can climb as usual without hindering other maintenance personnel from walking in the maintenance tunnel 11, which is convenient for multiple maintenance personnel to perform maintenance at the same time;

[0060] When the chassis monitoring mechanism completes its work, the remote control mobile seat 13 is reset. A wirelessly rechargeable power source is installed in the mobile seat 13. The power source provides power for the camera, the lighting, and the communication components. After the mobile seat 13 is reset, the wireless charging panel 8 installed on the maintenance tunnel 11 is close to the power source in the mobile seat 13 for charging, so that the chassis monitoring mechanism is always in a standby state;

[0061] The integrated control system for dangerous goods transport vehicles of the present invention can quickly inspect and repair the chassis of the transport vehicle by remotely controlling the chassis monitoring mechanism, thereby improving the operating efficiency of the inspection station and the safety of personnel.
