Description

Technical Field

[0001] The present invention relates to the field of vehicle epidemic prevention, and in particular to an automatic vehicle epidemic prevention system and an epidemic prevention method thereof. Background Art

[0002] As the global epidemic continues, the demand for engineering epidemic prevention technology has increased rapidly. The epidemic prevention in the construction area is highly controllable, and the difficulty of technological innovation is relatively small. However, in comparison, engineering commuting vehicles have become a key link in epidemic prevention control, but they are also a difficult link in supervision. This is mainly manifested in:

[0003] Frequent vehicle movement. When construction vehicles are outside the construction site, the risk of external cross-infection is high due to frequent movement, making it difficult to systematically and comprehensively control;

[0004] The number of passengers changes greatly. When the construction vehicles are out, the number of passengers may change frequently because they get on and off the vehicles at any time. If external personnel and project personnel ride in the same vehicle, there will be a greater epidemic prevention and safety risk, which will be very difficult to supervise.

[0005] There are so many vehicles and engineering vehicles that it is very difficult to supervise them by personnel and systems. A reliable and comprehensive automated supervision method must be adopted;

[0006] Disinfection is difficult. As a separate, enclosed epidemic prevention unit, engineering vehicles have high disinfection requirements. It is very difficult to carry out effective epidemic prevention and disinfection. A humane, intelligent, and full-coverage disinfection method must be adopted to ensure epidemic prevention safety.

[0007] At present, epidemic prevention supervision is usually carried out by epidemic prevention personnel on the people in the vehicle, but due to the above-mentioned reasons, supervision is often difficult and the epidemic prevention risks are very high; on the one hand, it is very difficult to avoid omissions in supervision; on the other hand, the full-time epidemic prevention personnel who supervise the vehicles themselves also face great epidemic prevention risks.

DETAILED DESCRIPTION

[0036] Embodiment 1:

[0037] like Figure 1-9 In the invention, an automated epidemic prevention system for vehicles is disclosed, comprising an integrated central control system, an on-board identification control terminal and an in-vehicle disinfection system. The in-vehicle disinfection system comprises a storage tank 3 for storing disinfectant and a spraying device 1 with variable direction. The spraying device 1 is connected to the storage tank 3. The on-board identification control terminal monitors and records the driver and passenger behaviors in real time. After the journey is over, the integrated central control system directs the spraying device 1 to spray and disinfect the driver and passenger's sitting position, touching position, coughing position, etc. at designated locations.

[0038] In a preferred embodiment, the in-vehicle disinfection system further includes an air pump 2 and an atomizing device 4 , the storage tank 3 is connected to the atomizing device 4 , and the air pump 2 drives the atomized disinfectant in the atomizing device 4 to enter the spraying device 1 .

[0039] The atomizing device 4 uses ultrasound to refine the disinfectant into fine mist. The air pump 2 pumps in fresh air, carrying the fine mist disinfectant into the spraying device 1 for spraying. The fine mist is easier to diffuse in the car, and can also avoid directly spraying the disinfectant to cause the car to be too humid. At the same time, it can replenish fresh air in the car and reduce the density of germs.

[0040] In a preferred embodiment, the spraying device 1 includes a structural tube 101 and a spraying head 102. The spraying head 102 is arranged in the structural tube 101. The spraying head 102 includes a balloon 107. A plurality of swingable fins 108 are provided at one end of the balloon 107. The plurality of fins 108 are arranged in a ring shape to form an injection port 114. A flexible neck 111 is provided at the other end of the balloon 107.

[0041] The volume and cross-sectional area of ​​the inner cavity of the balloon 107 are larger than those of the injection port 114. When the airflow passes through the inner cavity of the balloon 107 and reaches the injection port 114, the pressure increases suddenly, thereby increasing the injection force. The balloon 107 is provided with a flexible neck 111 made of materials such as rubber or silicone, which has a certain hardness and elasticity. The flexible neck 111 is connected to a fixed connecting block 113. The balloon 107 can swing around the flexible neck 111 to change the spraying direction of the spray head 102. A single fin 108 can swing independently around the connection with the balloon 107. A plurality of fins 108 can move in unison, and the injection port 114 can be opened or contracted, so that a wide range of spraying or fixed-point spraying can be selected. A plurality of fins 108 can also be partially opened and partially contracted, or uniformly swung in one direction.

[0042] In a preferred embodiment, the fin 108 is provided with a fin elastic portion 117 , and a spring ring 112 is sleeved on the outside of the spray head 102 near the fin elastic portion 117 , and the outer side of each fin 108 is connected to the outer wall of the balloon 107 through the nearest spiral spring coil of the spring ring 112 .

[0043] In the preferred embodiment, a plurality of first direction-changing bags 109 arranged circumferentially and a plurality of second direction-changing bags 110 arranged circumferentially are provided on the outside of the spray head 102. The first direction-changing bags 109 are provided on the outside of the balloon 107, and the second direction-changing bags 110 are provided on the outside of the fin plate 108. The volumes of the first direction-changing bags 109 and the second direction-changing bags 110 are variable and may be one or more small airbag cavities. An air control unit 5 is also provided, and the first direction-changing bags 109 and the second direction-changing bags 110 are connected to the air pump 2 via the air control unit 5.

[0044] The spring ring 112 mainly serves to constrain the fin plate 108 to its original state. The injection port 114 is originally in the shape of a trumpet. When the second direction-changing bag 110 is inflated, it squeezes the fin plate 108, causing the spring ring 112 to be pulled or compressed to undergo elastic deformation. The injection port 114 contracts, and the volume of the second direction-changing bag 110 is reduced when the air is exhausted. The spring ring 112 resumes its ring shape and pulls the fin plate 108 to reset. The working principle of the first direction-changing bag 109 is similar to that of the second direction-changing bag 110.

[0045] In the preferred embodiment, a first booster tank 103 is further provided, one end of the first booster tank 103 is connected to the atomizing device 4, and the other end of the first booster tank 103 is connected to the inner cavity of the spray head 102. A one-way valve 105 and a control valve 106 are respectively provided at both ends of the first booster tank 103.

[0046] In the preferred embodiment, the balloon 107 is further provided with a clamping cavity 115, and the fin plate 108 is further provided with an injection seam 116. The injection seam 116 of each fin plate 108 is connected to the clamping cavity 115. A second booster tank 104 is also provided, and a one-way valve 105 and a control valve 106 are respectively provided at both ends of the second booster tank 104. The clamping cavity 115 is connected to the air pump 2 through the second booster tank 104.

[0047] Since the cross-sectional area of ​​the injection slot 116 is much smaller than that of the injection port 114, the injected air is concentrated and the injection distance is long. Multiple injection slots 116 jointly inject an annular air curtain, and the range of the injection air curtain also changes with the swing angle of the wing plate 108, but it is always on the outside of the atomized disinfectant. The annular air curtain and the atomized disinfectant can work simultaneously or separately, and the injection slot 116 continuously injects low-pressure fresh air to reduce the density of germs and cool down the vehicle. When the vehicle is disinfected, the annular air curtain has a higher injection speed than the atomized disinfectant and is more concentrated, so it is sprayed farther and drives the nearby air to flow forward. At this time, after the atomized disinfectant is sprayed, the front and outside air have less obstacles to the injection, and there is a blockage with the annular air curtain. The external airflow cannot directly enter the atomized disinfectant laterally to form turbulence. In summary, the annular air curtain greatly increases the spray distance of the atomized disinfectant.

[0048] The first booster tank 103 and the second booster tank 104 mainly play the role of pressure storage and pressure boosting to further improve the spray force. The first booster tank 103 stores atomized disinfectant, and the second booster tank 104 stores fresh air.

[0049] In the preferred solution, the integrated central control system includes a real-time positioning terminal, a wireless interaction module, a computing storage unit and an in-vehicle communication module. The vehicle-mounted identification control terminal includes an integrated rearview mirror 6, which includes a touch screen mirror 601, a built-in camera and an infrared temperature measuring device, and also includes a display terminal, which includes a central control screen 8 and an external display screen 7 arranged outside the vehicle.

[0050] In the preferred solution, a tilted driver camera 602 and a passenger camera 603 are provided at both ends of the touch screen mirror 601, the display terminal also includes a rear display screen 9, and the on-board identification control terminal also includes a rear camera, which is built into the rear display screen 9.

[0051] The real-time positioning terminal facilitates real-time monitoring of the vehicle's position. The wireless interaction module is mainly used for communicating with the cloud server. The computing storage unit is the CPU of the epidemic prevention system. The in-vehicle communication module is mainly used for interactive communication among various electronic devices in the vehicle. The central control screen 8 is mainly used for operation of the front driver. The external display screen 7 is mainly used to display information to the outside. The main driver's camera 602 and the co-driver's camera 603 are mainly used to shoot the main driver and co-driver's positions. The rear display screen 9 is mainly used for passenger operation, and the rear camera is mainly used to shoot the rear passengers.

[0052] The prevention method is:

[0053] S1. Automatically identify the driver and passengers through automatic photo taking by the camera, compare with the data in the cloud server, confirm the driver and passengers' historical health status and recent travel history, and determine whether they have been in contact with the epidemic area;

[0054] S2. Monitor the expressions and movements of the driver and passengers to ensure that they do not cough or do other actions. At the same time, use an infrared temperature measuring device to detect the temperature of the driver and passengers to determine their current health status. If symptoms such as fever and cough occur, report them to the cloud server immediately.

[0055] S3: Analyze the destination location to determine whether it passes through an epidemic area. If so, re-plan the route to avoid it intelligently.

[0056] S4. After the trip, based on the monitored driver and passenger behaviors, such as coughing direction, door handle contact location, etc., the entire vehicle is disinfected and contaminated locations are disinfected locally.

[0057] Embodiment 2:

[0058] Integrated central control system. It consists of display unit, operation and storage unit, receiving and sending unit, and various chips, and is equipped with communication card when necessary. It is arranged in the background control center to uniformly control and manage various vehicle identification control terminals, receive information from vehicle identification control terminals, and send relevant instructions to them.

[0059] Vehicle identification control terminal. It is composed of a camera, an integrated storage and computing device, an integrated signal receiving and sending device, a display touch control screen, an external display screen, and various chips, and a communication card is configured when necessary.

[0060] The signal transmission and reception between the integrated central control system and the vehicle identification control terminal can select and reasonably adopt various modulation technologies and multiplexing technologies. Selectively use appropriate models of analog-to-digital converters, baseband chips, intermediate frequency chips, radio frequency chips, etc. to process, transmit and receive signal sources. To achieve reliable communication effects. The integrated central control system and the vehicle identification control terminal are equipped with computing software to process and transmit information.

[0061] The in-vehicle epidemic prevention and disinfection terminal consists of a disinfection liquid storage tank, a delivery pipe, a control signal line, a spray pump and a spray nozzle.

[0062] Mobile control terminals are specialized terminal control devices or various types of control terminal devices such as mobile phones and computers.

[0063] Working principle of vehicle identification control terminal.

[0064] The in-vehicle identification control terminal consists of a camera, an integrated storage and computing device, an integrated signal receiving and sending device, a display touch control screen, an external display screen, etc.

[0065] The rearview mirror in the car has been subversively designed to have comprehensive functions such as rearview mirror, touch screen, camera, calculation, recognition and processing, and amplification. The display touch control screen is integrated with a camera, which faces the inside of the car to dynamically identify the people in the car. The display touch control screen integrates storage and calculation devices, signal receiving and sending devices, calculation and processing software, and various chips, etc., and a communication card is configured when necessary. The inward-facing camera integrated on the display touch control screen captures the situation of people in the car in real time and uninterruptedly. The video signal is processed by the analog-to-digital converter, baseband chip, intermediate frequency chip, radio frequency chip, etc. built in the in-car identification control terminal and then transmitted to the integrated central control system. The software and hardware built into the integrated central control system can analyze the video signal and compare it with the engineering personnel base library pictures stored in the system library to identify and confirm the identity of the people in the car. If it is confirmed that the person does not belong to the engineering personnel or the temporary outsider in the warehouse, an alarm message will be sent to the management personnel.

[0066] The external display screen faces the outside of the vehicle. The display screen can be a single display screen or can be combined with the front windshield or side glass of the vehicle to display directly on a certain area of ​​the vehicle glass. The external display screen is connected to the vehicle identification control terminal through wires and signal lines.

[0067] The in-vehicle identification control terminal has the function of comprehensively and preliminarily judging the symptoms and terrorist attack dangers. Specifically, a large number of facial expression features of various typical symptoms and corresponding facial dot matrix information are pre-entered in the background database of the integrated central control system for identification and comparison. With the support of the system, the vehicle identification terminal camera will capture the facial dot matrix information of the passengers, the in-vehicle identification control terminal, and compare it with the facial expression dot matrix of various typical symptoms in the above-mentioned background database, so as to preliminarily judge the suspected symptoms of the personnel. Symptom judgment also combines the infrared rays of the camera to measure the temperature of the personnel. Combined with the camera's recognition and comparison of features such as coughing movements and painful expressions for comprehensive judgment, the recognition software in the system can also realize the comprehensive analysis function of multiple photos, that is, through the comprehensive analysis of a person's specific movements in multiple consecutive photos, the physical and mental conditions of the person can be analyzed.

[0068] If a terrorist suddenly breaks into the car and takes the occupants hostage, the in-car identification control terminal will collect video and audio signals through cameras and microphones, and then compare them with the characteristic images, videos, and audios of terrorist attacks that have been pre-entered into the background database of the integrated central control system as comparison templates. If it is determined to be a dangerous situation such as robbery or terrorist attack, an emergency alarm signal will be sent to the integrated central control system so that the background personnel can respond in time.

[0069] The above comparison principle is described as follows: The principle of the integrated central control system for comparing and discovering symptoms and terrorist attacks is to identify the basic characteristics of these conditions and behaviors.

[0070] For example, the factors of illness are: fever (infrared sensing detection and other methods, not detailed here), shortness of breath (focus on movement characteristics and frequency), coughing (movement characteristics and frequency), discomfort (collecting and comparing feature points of facial distortion), etc.

[0071] For example, the elements of a terrorist attack are: holding a weapon (collecting weapon feature points and comparing them with feature photos in the image library), a ferocious face (collecting facial feature points and comparing them with feature photos in the image library), holding people in the car hostage (collecting feature points such as strangling the neck and using the weapon against others and comparing them with feature photos in the image library), verbally threatening people in the car (comparing and identifying the tone of threatening audio and key words), etc.

[0072] The in-vehicle identification control terminal also serves as a vehicle safety reminder.

[0073] Vehicle rear-end collision prevention. The in-vehicle identification control terminal can track the driving conditions of the rear vehicle in real time through the rear glass. When the system determines that a rear-end collision may occur with the vehicle behind, it will promptly send a voice prompt to the rear driver through the external speaker installed at the rear of the vehicle, and can also flash the border light strip to warn the driver of the vehicle so that the driver of the vehicle can avoid it.

[0074] Vehicle tailgating monitoring. The in-vehicle identification control terminal can also identify the rear or surrounding vehicles through the display touch control screen camera or the vehicle's panoramic parking camera, and analyze whether the rear or surrounding vehicles are tailgating vehicles through the integrated central control system analysis software. If it is a permitted trailing vehicle, no alarm will be triggered; if it is not a permitted vehicle, it will be determined as a tailgating vehicle and an alarm will be triggered to the driver and the backend, who will conduct further analysis, judgment and appropriate disposal.

[0075] External display function.

[0076] An external display screen is set up, that is, a dual-screen display inside and outside. The external display screen can display brief information of the driver and passengers in the car identified by the system. External inspectors can understand brief information of the people in the car through the display screen, so that the people in the car do not need to get off the car for inspection, meeting the safety and epidemic prevention requirements of contactless inspection. The external display screen is connected to the in-car identification control terminal with wires and signal lines, and only realizes the function of the display.

[0077] Determination of driver and passenger movement trajectory.

[0078] The movement trajectories of drivers and passengers are accurately monitored. Only through strict monitoring can the effect of strict epidemic prevention and control be achieved.

[0079] In addition to configuring a GPS positioning device in the vehicle identification control terminal to monitor the vehicle's driving trajectory, the vehicle needs to declare its movement trajectory in advance before going out. If the actual travel trajectory deviates from the predetermined trajectory or does not stop at the specified location, the system will automatically determine it as a violation. The system will automatically enter the violation information and send a text message to the person responsible. If the vehicle breaks down, it should be reported on the touch screen of the identification terminal. The occupants of the vehicle cannot leave the driving seat and are monitored by the camera of the identification terminal to avoid being judged as a violation.

[0080] This patent can also accurately monitor the movement of the driver and passengers. When the vehicle is parked, the driver and passengers can be monitored by the vehicle's built-in panoramic parking camera when they are around the vehicle. When the driver and passengers have unsafe contact with outsiders without maintaining social distance, the vehicle identification control terminal will issue an audible and visual alarm and send a screenshot and violation information to the integrated central control system.

[0081] When drivers and passengers need to go out on foot, they need to declare the reason, destination and time of the trip on the vehicle identification control terminal. They can only travel after approval. After approval, the travelers need to associate their mobile phones with the vehicle identification control terminal. The association method can be any appropriate method, such as entering their phone number in the vehicle identification control terminal. In this way, the vehicle identification control terminal can monitor the trajectory and duration of the travelers' activities through their phones. If there is a deviation from the predetermined trajectory, illegal detention in the middle, or excessive detention, the vehicle identification control terminal will issue an audible and visual alarm and send a screenshot and violation information to the integrated central control system.

[0082] Driver control.

[0083] Identify and control the driver. The vehicle identification terminal can also realize the permission control of the driver. When the vehicle identification terminal recognizes through the camera that the person in the driver's seat is not the driver permitted by the system library, the vehicle identification terminal sends an alarm message to the system. At the same time, the integrated central control system sends a control command to the vehicle identification terminal to prohibit the vehicle from starting. The vehicle identification terminal connects with the vehicle's own control system through electrical signals and data signals, and sends a command to the vehicle's own control system to prohibit the vehicle from starting, thereby preventing unauthorized personnel from operating the vehicle.

[0084] Working principle of the in-vehicle epidemic prevention and disinfection terminal.

[0085] Automated and intelligent epidemic prevention and disinfection in the car.

[0086] The in-vehicle epidemic prevention and disinfection terminal consists of a disinfection liquid storage tank, a delivery pipe, a spray pump, a control signal line, and a spray nozzle. In principle, the disinfection liquid storage tank and the spray pump are arranged close to the engine. The spray pump is powered by the battery or generator in the vehicle. The spray pump is connected to the computing and storage device built into the in-vehicle identification control terminal through a control signal line. One or more spray nozzles are arranged at appropriate locations in the vehicle.

[0087] Set the in-vehicle disinfection mode or disinfection restrictive conditions on the display touch control screen or on mobile phones, computers and other terminal devices that are connected to the in-vehicle epidemic prevention and disinfection terminal. For example, how many times a day, what time period, and what conditions are met to start disinfection. The in-vehicle identification control terminal starts to enter the disinfection program according to the time and conditions. If the vehicle is still driving during the scheduled disinfection period, the disinfection will be postponed. When the disinfection starts, the system first confirms that the vehicle is in a stopped state. The identification terminal camera first confirms that there are no people or other animals in the car and there are no other conditions that are not suitable for disinfection, and then raises the window to avoid forgetting to close the window when parking, which affects the disinfection effect. When the disinfection starts, the battery in the car powers the spray pump, and the spray pump sprays the disinfection liquid in the disinfection liquid storage tank into the car through the spray nozzle. At the same time, the air conditioning system in the car starts, sucks the disinfection liquid into the air conditioning duct, and disinfects the duct. The disinfection in the car can also be started at any time through the mobile control terminal.

[0088] Introduction to the principle of spray nozzles

[0089] One-way air inlet valve and booster tank. The disinfectant sent from the spray pump and delivery pipe to the spray nozzle first passes through the one-way valve and then enters the booster tank. Through the one-way valve and the accumulated pressure of the booster tank, it can reach the required pressure set by the system, realizing the requirements of pressurized injection and fixed-point disinfection.

[0090] Pressure-controlled exhaust valve. The outlet of the booster tank is connected to the pressure-controlled exhaust valve, which is connected to the master control system of the device. The master control system controls the pressure value of the pressure-controlled exhaust valve according to the mode set by the user. When the set pressure value is reached, the pressure-controlled exhaust valve opens, and the disinfectant is sprayed out into the swing ventilation ball hinge.

[0091] Swing ventilation ball hinge. The swing ventilation ball hinge and the jet fin plate together achieve the effect of guiding high pressure jet. The swing ventilation ball hinge is connected to the pressure controlled exhaust valve through a transition soft curtain to avoid leakage. The transition soft curtain is made of soft and airtight material and is connected to the pressure controlled exhaust valve and the swing ventilation ball hinge respectively. The swing ventilation ball hinge can slide up and down on the ball hinge slot to adapt to the swing of the swing ventilation ball hinge. The ball hinge slot is fixed on the rigid delivery pipe, so that the swing ventilation ball hinge can change direction on the rigid delivery pipe. The direction changing of the swing-ventilated ball hinge is achieved through the first direction-changing bag. When the swing-ventilated ball hinge needs to change direction, one or more of the dozen first direction-changing bags surrounding the circumference of the swing-ventilated ball hinge are inflated under the action of the system air tank according to the command control of the master control system. After the inflated air bag becomes larger, it squeezes the air bag working plate on its upper part, and the air bag working plate fixed on the swing-ventilated ball hinge pushes the swing-ventilated ball hinge to achieve directional angle swing. The first direction-changing bag is made of highly elastic materials such as rubber and soft plastic, and is lined with spring steel wire mesh. When the swing-ventilated ball hinge needs to return to its position, after the first direction-changing bag is deflated, it returns to its position under the action of the returning force of the spring steel wire mesh inside the air bag, driving the swing-ventilated ball hinge to return to its position.

[0092] Jet fins. The jet fins are composed of several to dozens of vertical plates, one end of which is connected to the swing ventilation ball hinge by a hinge. The outer opening of the jet fins can be closed or expanded as needed. The closing or expanding is completed by the second direction-changing bag arranged on the outside and the spring ring arranged on the inner circle under the control of the central control system. When the jet fins need to be closed, the central control system controls the air tank to inflate one or several of the second direction-changing bags arranged on the outside of the jet fins. The airbags become larger and push the fins to achieve partial or overall closing of the jet fins. Moreover, when the jet fins are in the closed state, combined with the joint action of the pressure-controlled exhaust valve, the injection pressure can be further ensured. After the fin airbag is deflated under the action of the central control system, on the one hand, the second changing bag has the same structure as the first changing bag, and under the action of the spring steel wire mesh arranged inside it, the second changing bag retracts to leave space for the fin to return; on the other hand, under the action of the spring ring inside the jet fin, the jet fin opens and returns, and the spring ring is compressed when the jet fin is closed. When the second changing bag is deflated, the spring ring pushes the jet fin to open and return under the action of the return expansion force.

[0093] The principle of fixed-point spraying and disinfection.

[0094] In general, the whole space is disinfected without differentiation by spraying nozzles in the car, which adopts low-pressure diffusion combined with all-round swinging. However, if fixed-point or key area disinfection is required, it can be achieved through the joint action of the central control system and the spray nozzles. Assuming that the rear door handles in the car need to be accurately disinfected, the central control system first calculates the angle at which the spray nozzle needs to swing and the injection pressure value determined according to the distance and other related parameters through the relative position of the door handles in the car. Then, the one-way air intake valve, the boost tank, and the pressure-controlled exhaust valve are used to ensure that the disinfection liquid-gas mixture reaches the predetermined pressure value, and then the ventilation ball hinge and the injection fin plate are swung to the corresponding angle to align with the door handle position, so as to achieve precise spraying and disinfection.
