Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, and in particular to an intelligent transport vehicle based on face recognition. Background Art

[0002] In the auto parts industry, various transport vehicles are often used in workshops to transport goods over short distances. They play an important role in loading, unloading, stacking and delivering goods. Since transport vehicles are also powered vehicles, they must be certified and cannot be used by non-designated personnel. Conventional transport vehicle management technology is generally managed by manpower, which is relatively vague and does not meet the practical safety prevention and control requirements.

[0003] In other fields, facial recognition systems based on biometric technology are generally used for security protection. This technology has been widely used in government, military, banking, social welfare security, e-commerce, security and defense and other fields. However, for the auto parts industry, especially for transport vehicles in workshops, its application is not common. It can be learned from the publicly available technical information on the market that there is a technology that proposes a vehicle control system with facial recognition. After the vehicle is opened with a physical key, a secondary verification is performed using a mobile phone APP to determine whether the person is a qualified driver. The actual control logic is unreasonable. It actually sets operational obstacles for qualified drivers, while qualified drivers can directly ignite with a physical key. There is also a technology that proposes to set a protective door on the side of the vehicle cab. , only after passing the facial recognition and cooperating with Bluetooth technology can the protective door be opened to get on the car. This technology can indeed prevent non-qualified drivers from opening the door to get on the car, but it still sets up operational obstacles for qualified drivers. At the same time, the situation of changing drivers midway after the qualified driver ignites the car cannot be effectively controlled, so this technology also has loopholes. In addition, there is a technology that proposes to install a facial recognition device in the cab. After ignition, the vehicle cannot operate the walking system. The walking system can only be operated after recognition by the facial recognition device, that is, the ignition part and the walking system are independently controlled, and the facial recognition device does not control the ignition part. Due to its technical limitations, facial recognition must be enabled after ignition, which is a secondary verification, a waste of time, and not intelligent enough, so there are also major disadvantages;

[0004] In addition, existing transport vehicles often encounter the problem of limited clearance height when passing through various workshops. Usually, the operators rely on their own skills and experience to judge the clearance height, which leads to very high experience requirements for the operators;

[0005] To sum up, it is necessary to develop a truly intelligent and safe smart transport vehicle in combination with a face recognition system to address the safety and control defects of workshop transport vehicles in the existing technology, while solving the problem of requiring manual experience to judge the height.

[0038] Working principle: The control box 30 is provided with a system for operating the intelligent transport vehicle, which supports wireless communication with the upper computer of the management center. The facial information of the transport vehicle and the driver can be entered into the mobile phone APP applet corresponding to the system. The system automatically counts down the annual inspection time according to regulations, and displays a reminder in the system one month before the expiration. At the same time, the system is used to control the driving qualification of the transport vehicle, record and identify unsafe driving behaviors, and issue warnings. The system can count the mileage, status, number of violations, etc. of the transport vehicle by time dimensions such as weeks, months, and years. The system can also cooperate with the common electronic fence technology and speed monitoring technology on the market to monitor the operating range of the transport vehicle. When an alarm occurs, the warning light 31 flashes and the speaker in the intercom 32 gives a prompt. The microphone in the intercom 32 can record the sound during driving and can also communicate with the monitoring center. The active face recognition integrated machine 34 is independently powered by the second battery pack 5. It is in a dormant state when not used daily. It is awakened by the signal of the pressure sensor module 6. After being awakened, it is quickly driven by the third electric telescopic rod 33 to extend the shaft to drive the lifting and adjustment, and is captured and recognized by the second camera 26. After recognition, the control box 30 will have the following operations: if the driving permit information and annual inspection information are passed, the prompt sound reminds that the transport vehicle is about to be powered on and started; if the driving permit information is passed and the annual inspection information is about to expire, the prompt sound reminds that the transport vehicle is about to be powered on and reminds the annual inspection expiration time; if the driving permit information is passed but the annual inspection information is expired, the prompt sound reminds that the transport vehicle will not be started and please inspect it annually;If the driving permit information is not passed, a prompt sound will be sounded to remind the transport vehicle not to start, and a warning will be issued at the same time. The prompt sound reminds non-permitted drivers that they are not allowed to operate special equipment. The active face recognition integrated machine 34 is very fast when performing recognition. Permitted drivers whose annual inspection has not expired do not need to perform the ignition action after getting on the vehicle. The vehicle can be recognized and started while fastening the seat belt, which is very intelligent. During the operation of the transport vehicle, the driving behavior is monitored by the third camera 27. When it is detected that the permitted driver has left, the vehicle automatically turns off to avoid being used by non-permitted drivers and to avoid safety accidents. A common wireless charging and discharging plate on the market is set on the ground in the transport vehicle parking area. After the transport vehicle is parked, it can be charged through the wireless charging receiving plate 29. The second battery pack 5 box control box 30 is independently powered. The information of the person getting on the vehicle is recognized through the pressure sensor module 6 to wake up the active face recognition integrated machine 34. The image captured by the first camera 13 can be displayed on the display screen 11. The passing of the transport vehicle can be observed through the first camera 13 without the need for empirical judgment. It can be intuitively seen that the first electric extension The extension of the retracted rod 14 can drive the installation box 8 to rise and fall, which is actually to adjust the height of the first distance sensor 16 and the first laser indicator 17. When it is unclear whether the lowest height of the high obstacle in the area to be passed is available for passing, the transport vehicle is placed directly at the area to be passed, and the light beam emitted by the first laser indicator 17 confirms the detection height of the first distance sensor 16, and the first electric telescopic rod 14 extends the axis to drive the height adjustment, so that the first distance sensor 16 measures the position of the door frame or wall of the area to be passed and the first distance sensor 16 is in a horizontal state. The second electric telescopic rod 25 drives the movable box 10 to rise until the light beam emitted by the second laser indicator 19 hits the lowest point of the high obstacle. The control box 30 collects the distance information detected by the first distance sensor 16, the distance information detected by the second distance sensor 18, and the angle information detected by the inclination sensor 20, and the passable height can be calculated and displayed on the display screen 11, which overcomes the disadvantage of judging the height by experience in the prior art and greatly improves safety. ;
