When the vehicle blocks the first grating module and the second grating module at the same time, the quick inspection system accurately and automatically avoids the cab through high-speed delay calculation, and the X-ray The rays are immediately turned on to scan and detect the car body; the X-ray receiving column is installed on the other side of the lane and is located directly opposite the X-ray transmitting box, which is used to receive the fan-shaped X-ray beam, and through photoelectric conversion, signal processing, etc., quickly generate X-ray detection images and display them on the terminal computer screen; the indicator light is composed of blue, yellow and red bar-shaped indicator lights and is installed on the X-ray transmitting box; the client terminal is used to control the use of the quick inspection system, and the client terminal is composed of a host, a display, an operating keyboard and a control mouse. The overall installation is relatively simple during setup, the safety during use is more reliable, and the operation is more convenient. There is no need for staff to conduct separate inspections around the vehicle. Remote and accurate detection is achieved through automation, which effectively improves the efficiency of inspection work, speeds up the travel of green-pass vehicles, avoids congestion caused by manual inspections and the occurrence of missed inspections and wrong inspections, and effectively reduces labor costs and time costs.
[0009] Its working principle is that the Green Pass Quick Test System adopts transmission X-ray detection technology. A ray source emission box is fixedly installed on one side of the entrance of the Green Pass, and a linear array detector receiving column is fixedly installed on the other side. Under normal circumstances, the Green Pass is used as a general channel to allow non-Green Pass detection vehicles to pass. When the Green Pass vehicle that needs to be detected enters the channel, first press the "Reservation" button, which notifies the system terminal that the vehicle needs to be tested. At this time, the lifting machine will lower the lifting bar (usually in the raised state), and the terminal control room will lift the lifting bar after confirming that there is no vehicle in the channel, and reserve the vehicle to enter the Green Pass detection area. At this time, the camera subsystem captures the vehicle license plate and front photo, and monitors the vehicle's driving status in real time. When the first set of gratings detects the position of the vehicle's front end, the system begins to record the vehicle's current position and time to prepare for the accurate calculation of the cab's avoidance. The system accurately calculates the cab's avoidance distance based on the position and vehicle speed. When the vehicle's front end is detected by the second set of gratings, the system quickly and accurately calculates the driving speed to determine the cab's avoidance distance and the precise X-ray initial emission time. Then the X-ray unit is immediately started to scan and detect the cargo compartment (the cab has entered the safe area at this time). When the second set of gratings detects the rear of the vehicle, the system stops scanning and the ray detection ends. At this time, the terminal control display screen displays the vehicle box detection results, loading rate, vehicle information, etc. Due to the different densities of the loaded goods, the ray transmittance is different, so the signal strength received by the linear array detector is also different. After signal processing and image processing, the outline and loading status of the goods can be clearly displayed on the terminal screen. The toll collector determines the type of loaded goods based on the X-ray image displayed on the screen, and finally determines whether the vehicle meets the conditions for green pass vehicle toll reduction based on the automatically calculated loading rate. The system provides direct evidence for free release or reasonable charging, and the detection image is stored in the terminal server for later verification of relevant information.
[0010] Its inspection process is that when the vehicle drives to the green pass fast inspection channel, it is ready to be inspected. First, press the "Appointment" button to prepare for inspection. This process is the vehicle inspection process; when the lifting bar lifts the horizontal bar and the vehicle enters the green pass detection area, the camera subsystem captures the vehicle license plate (including license plate recognition) and front photos, while monitoring the vehicle's movement in real time, and the side of the vehicle is also photographed. When the first set of gratings detects the front of the vehicle, the system begins to record the current position and time to prepare for the accurate calculation of the cab avoidance, and reminds the staff that the vehicle is about to start scanning and detection. This process is a vehicle pre-inspection. When the vehicle moves forward and the front of the vehicle is detected by the second set of gratings, the vehicle speed can be accurately calculated (the distance between the two sets of gratings is fixed), thereby determining the time when the X-ray scan starts (cab avoidance distance), and turning on the warning light at the same time. Once the avoidance distance is reached, the cold cathode X-ray instantly starts scanning the cargo compartment. After the linear array receiving column opposite the channel receives the light signal, it is processed and the detection result is displayed on the system terminal screen. The toll collector determines the type of loaded goods based on the display and the automatically calculated loading rate, and finally decides whether the vehicle meets the conditions for toll reduction and exemption for green-pass vehicles. This process is the X-ray cargo compartment detection process. When the first set of gratings detects that the rear of the vehicle has moved forward and left, the lifting bar machine drops the bar to ensure that no other vehicle enters the detection area during the detection process. When the second set of gratings detects the rear of the vehicle, the system stops scanning, the X-ray warning light goes out, and the ray detection ends. This process is the end of the detection process. When the vehicle detection is completed, the driver logs in the relevant information and the vehicle leaves the toll booth. The toll collector presses the "Confirm" button, the lifting bar machine is lifted, and the system returns to the waiting state. At this time, if a vehicle has made an appointment, the detection process is repeated to complete the green-pass detection.
[0011] Preferably, the first grating module and the second grating module use grating components of the same specification, so that the overall cost is lower and the selection of grating modules is more convenient.
[0012] Preferably, the operation keyboard includes a letter key, direction keys and function keys, and the function keys include an "OK" key: save the current test result and end the test, and enter the next waiting for inspection state. "Exit" key: the current toll collector exits the system and waits for the next toll collector to log in. "Green Pass Appointment" key: open the appointment green pass detection reminder. "Amount", "Goods" keys: cursor selection. If you press the "Amount" key, you can enter a specific amount. "Cancel" key: delete content, used when input errors occur or information needs to be modified. "Certificate" key: call up the high-speed scanner to collect certificate information. "Lift the bar" and "Lower the bar" keys: control the bar lifter to lift or lower the bar.
[0013] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
