[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0029] Forklifts are highly standardized and versatile, and are widely used in factories, mines, warehouses, stations, ports, airports, freight yards, circulation centers and distribution centers. They can also enter cabins, carriages and containers to load and unload, stack, destacker and carry out short-distance transportation of finished parts, packages, pallets, containers and other containers. They are indispensable equipment for pallet transportation and container transportation.
[0030] The main working attachment of a forklift is the cargo fork. After being equipped with other working attachments, it can also be used for loading and unloading bulk cargo, non-packaged cargo, long and large cargo, and for short-distance transportation. Forklifts are widely used. They are not only widely used in road transportation, railway transportation, and water transportation, but also in material storage and transportation, postal services, and military departments.
[0031] Forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment. They are widely used in various sectors of the national economy, such as stations, ports, airports, factories, warehouses, etc. During the Second World War, forklifts were developed. With the rapid development of the economy, the material handling of most enterprises has been separated from the original manual handling, and replaced by mechanized handling mainly based on forklifts. Therefore, for a long period of time in the past, the demand for forklifts has been growing at a double-digit rate every year.
[0032] Forklifts have the following advantages:
[0033] 1. Improve material operation efficiency, reduce labor intensity, and improve working conditions; save labor and improve labor productivity. According to the economic benefit analysis of forklift use, one forklift can replace the physical labor of 8 to 15 loading and unloading workers. When the forklift is operating, the loading, unloading, stacking, and handling of goods can be mechanized by relying solely on the driver's operation without the auxiliary labor of loading and unloading workers. This not only ensures the safe production of the enterprise, but also greatly reduces the labor occupied and the labor intensity, thereby greatly improving the operation efficiency and achieving significant economic benefits.
[0034] 2. Shorten operation time and speed up material turnover, thereby increasing the utilization rate of vehicles and ships and improving production efficiency.
[0035] 3. Make full use of space and save warehouse area. When using forklifts, goods can be piled higher, currently reaching more than 10 meters (m), which can increase the warehouse volume utilization rate several times.
[0036] 4. Use pallets and containers to hold goods, which simplifies the packaging of goods, saves packaging materials, reduces loading and unloading costs, and improves operating efficiency and the safety of goods.
[0037] 5. Using forklifts can relieve heavy physical labor, reduce cargo damage and worker injuries, and improve the safety of operations.
[0038] 6. Forklift operation can reduce damage to goods, improve the safety of operations, and achieve safe loading and unloading.
[0039] 7. Compared with large loading and unloading machinery operations, forklift operations have the advantages of low cost and low investment.
[0040] Therefore, forklifts should be preferred in logistics loading and unloading operations. Forklifts play a very important role in the industrial logistics system. It can be said that without forklifts, express delivery, logistics, warehousing, and factories will even be paralyzed. With the continuous increase in labor costs, it is inevitable to replace manual labor with machinery.
[0041] However, since forklifts are easy to drive, there are often illegal behaviors such as driving without a license during daily use, which can easily cause safety hazards. In order to solve the above problems, the utility model provides a multifunctional forklift, and the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings.
[0042] Figure 1 Schematic diagram of an optional multifunctional forklift shown in the embodiment of the utility model. Figure 1 The multifunctional forklift in this embodiment includes a face recognition device 1 and a controller 2, and the face recognition device 1 is connected to the controller 2.
[0043] Wherein, the face recognition device 1 is used to perform face recognition on the collected facial image of the driver;
[0044] Controller 2 is used to control the multi-functional forklift to start when the face recognition is passed.
[0045] In an optional embodiment, the controller 2 is an onboard computer or a vehicle controller, including control of the vehicle body, battery, braking system, drive system, etc.
[0046] In some embodiments, after the multifunctional forklift is unlocked and the entire vehicle is powered on, the face recognition device 1 starts and triggers the face recognition function. When a face is detected, the face recognition device 1 collects face data and performs matching verification.
[0047] In some embodiments, the face recognition device 1 is also used to collect face image data; extract feature information of the face image, wherein the feature information may be a scale invariant feature transform (SIFT) feature, an affine scale invariant feature transform (ASIFT) feature, a contour feature, etc.; match the feature information with pre-stored feature information, wherein the pre-stored feature information is feature information of a driver with authority to drive a multi-functional forklift; and confirm that the matched face has passed face authentication.
[0048] It is understandable that when the face recognition device 1 successfully performs face recognition system comparison, a face recognition pass signal is sent to the controller 2. When the controller 2 receives the face recognition pass signal, the engine of the multi-functional forklift can be ignited and started.
[0049] In some embodiments, the face recognition device 1 includes an artificial intelligence (AI) camera, which is used to: collect the facial image of the driver, analyze and process the collected facial image of the driver, and compare the processed facial image with the facial image of a driver who can drive a multi-functional forklift.

If the camera sealing glass on the camera housing needs to be cleaned, the second motor can be started, and the camera housing can be driven to rotate by the second motor to move the camera sealing glass on the camera housing to the bottom of the cleaning mechanism. At the same time, the spring on the supporting component will push the cleaning mechanism downward, so that the cleaning mechanism is tightly attached to the camera housing, and the camera sealing glass is cleaned by the sponge block on the cleaning mechanism.
