In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this specification, "multiple" means two or more, unless otherwise explicitly and specifically defined.

[0029] Example 1: Figure 1-Figure 10As shown, a commercial vehicle intelligent rotary lock system based on the Internet of Things includes a trailer 1, a battery pack 2, a locking system 3 and a monitoring system. The trailer 1 is composed of a body 11 and a front 12 connected together. A mounting position is arranged at the rear side of the front 12. The front 12 is detachably connected to the body 11 through the mounting position. The locking system 3 includes a braking system locking unit, a compartment locking unit 32 and a box door locking unit 33. The braking system locking unit is used to lock the braking system of the trailer 1. A container 5 is fixedly installed on the top of the body 11. A side of the container 5 close to the rear of the body 11 is provided with The double-opening door 6 has a locking rod 7 on the outside of the door 6. The locking rod 7 is vertically arranged. A plurality of bearings are arranged in the middle of the locking rod 7. Each bearing is fixedly connected to the door 6 through a bearing seat. Because the locking rod 7 is fixedly installed on the outside of the door 6 through the bearing, the locking rod can rotate axially. A handle 8 is fixedly installed in the middle section of the locking rod 7. A padlock 9 corresponding to the handle 8 is arranged on the door 6. A lock head 10 is sleeved on the top end and the bottom end of the locking rod 7. A color difference ring is bonded to the periphery of the lock head 10. The car locking unit 32 is used to fix the container 5 on the top of the vehicle body 11. The door locking unit 33 includes a shell 331, a fixing seat 332, a fill light 333 and a camera 334. The shell 331 is fixedly installed on the top of the rear of the vehicle body 11, and the fixing seat 332 is fixedly installed inside the shell 331; the top of the shell 331 is provided with a locking hole corresponding to the lock head 10 at the bottom end of the locking rod 7. The locking hole is used for the door to drive the locking rod 7 to move when the door is closed, and the lock head 10 at the bottom end of the locking rod 7 can be inserted into the shell 331, and then through the handle 8 controls the locking rod 7 to rotate, and the lock head 10 at the bottom end of the locking rod 7 rotates synchronously, and then the handle 8 on the locking rod 7 is locked by the padlock 9. The locking hole is only used to allow the lock head 10 and the locking rod 7 to enter and exit the housing 331 at a certain angle. After the lock head 10 is inserted into the housing 331 from the locking hole, the locking rod 7 is rotated to change the angle of the lock head 10 inside the housing 331. At this time, the lock head 10 cannot pass through the locking hole to leave the housing 331. The locking rod 7 must be rotated to change the angle of the lock head 10 before it can pass through the housing 331 again.At this time, the camera 334 and the fill light 333 are controlled to work. The fill light 333 is fixedly installed on the housing 331 of the camera 334. The camera 334 is fixedly installed inside the housing 331. The camera 334 is used to obtain a real-time image of the lock head 10 at the bottom of the locking rod 7. Because a color difference circle is provided on the lock head 10 at the bottom of the locking rod 7, it is possible to know whether a person opens the door 6 while driving through the real-time monitoring of the camera 334 and the relative positions of the handle 8 and the padlock 9. When the camera 334 recognizes that the locking rod 7 rotates while driving, it notifies the braking system locking unit to lock the braking system of the vehicle to ensure that the vehicle stops at a uniform speed, and issues an alarm for remote notification. The car body locking unit 32 is composed of a plurality of data-sharing smart rotary locks 32A. A plurality of accommodating grooves are evenly spaced on both sides of the top of the car body 11 along the length direction of the car body 11. A smart rotary lock 32A is provided inside each accommodating groove. The smart rotary lock 32A includes a servo motor The servo motor 32A1 is provided with a round rod 32A2 and a locking block 32A3. One end of the round rod 32A2 is fixedly connected to the output shaft of the servo motor 32A1 through a coupling. The locking block 32A3 is sleeved on the end of the round rod 32A2 away from the servo motor 32A1. The servo motor 32A1 is fixedly installed at the bottom of the accommodating groove. The output shaft of the servo motor 32A1 is located at the top of the servo motor 32A1. The top periphery of the locking block 32A3 is axially uniformly provided with a plurality of downwardly penetrating grooves. The bottom surface of the locking block 32A3 is arranged in an arc shape. The bottom of the container 5 A positioning block 13 is provided with a plurality of corresponding accommodating grooves, and a locking hole connected to the accommodating groove is provided at the bottom of the positioning block 13. A plurality of protrusions formed integrally with the positioning block 13 are evenly arranged circumferentially at the inner bottom end of the locking hole. When the servo motor 32A1 drives the round rod 32A2 to rotate, the locking block 32A3 rotates axially. Since the bottom end surface of the locking block 32A3 is arc-shaped, it can slide well into the accommodating groove at the bottom of the positioning block 13, and as the locking block 32A3 rotates, the bottom end surface of the locking block 32A3 and the bottom of the positioning block 13 are locked. The top surfaces of the protrusions in the receiving grooves are attached to each other and pressed against each other, thereby achieving the purpose of locking the positioning block on the vehicle body. When it is necessary to loosen, it is only necessary to control the locking block 32A3 to rotate in the opposite direction so that the locking block 32A3 is located at the intervals between the multiple protrusions. At this time, when the container is lifted, the container will not be locked on the vehicle body due to the action of the positioning block 13. Therefore, in fact, the locking block 32A3 and the multiple protrusions in the receiving grooves of the positioning block 13 form a mutually staggered canine structure. Multiple front cameras and multiple front ranging radars are arranged at the top of the front of the vehicle 12. ;

[0030] like Figure 1-Figure 10As shown, the top end of the locking rod 7 is sleeved with an automatic rotator 14, one side of the automatic rotator 14 is fixedly connected to the vehicle door 6, and the automatic rotator 14 is used to rotate the locking rod 7. The automatic rotator 14 includes a sealing cover 141, an electric motor 142, a cam 143, a connecting rod 144 and a disc 145. The sealing cover 141 is sleeved on the top end of the locking rod 7 through a sealing bearing, and the outer side of the sealing cover 141 is bolted and fixed to the vehicle door 6. The disc 145 is sleeved on the segment of the locking rod 7 located inside the sealing cover 141, and the electric motor 142 is fixedly installed. At the inner bottom of the sealing cover 141, the output shaft of the electric motor 142 is located at the top of the electric motor 142, and the cam 143 is sleeved on the output shaft of the electric motor 142. A cylindrical protrusion is vertically arranged on the top periphery of the cam 143. One end of the connecting rod 144 is rotatably connected to the cylindrical protrusion, and the other end of the connecting rod 144 is hinged and fixed to the disc 145. The automatic rotator 14 is used to realize automatic control of the locking rod 7, further reducing the risk of manual intervention, so that the internal cargo of the entire container is better protected and the safety of the cargo is improved.

[0031] like Figure 1-Figure 10 As shown, the cross section of the lock 10 is rectangular, a concave hole penetrating from front to back is arranged in the middle position of one side of the lock 10, the periphery of the lock 10 is arranged with an acute angle chamfered shape, a first pressure sensor is arranged at the bottom end of the lock 10, and the first pressure sensor is used to detect the contact pressure between the surface of the lock 10 and the inner wall of the shell 331, a second pressure sensor is arranged at the bottom of the locking block 32A3, and a third pressure sensor is arranged at the bottom of the positioning block 13. The first pressure sensor, the second pressure sensor and the third pressure sensor are all connected to the monitoring system wired electrical signal through a wiring harness, and numerical scales are arranged at equal intervals on the surface of the color difference circle. A visual monitoring system, a distance comparator, a power controller and a protection module are arranged inside the cab of the front of the vehicle 12. The front camera, front ranging radar, and visual monitoring system are all connected to the distance comparator by wired electrical signals, the distance comparator is connected to the power controller by wired electrical signals, the protection module is arranged inside the power controller, the protection module is used to provide instantaneous cooling for the power controller when the power controller is overloaded, the power controller is connected to the driving system of the front of the vehicle 12 and the braking system of the vehicle body 11 by wired electrical signals, the power controller is connected to the braking system locking unit by wired electrical signals through a wiring harness, the first pressure sensor, the second pressure sensor, and the third pressure sensor can provide comparison of the monitoring data of the camera 334 and the servo motor 32A1 through the detection of pressure values, so as to avoid the problem of failure of the entire system due to failure of a single detection method.

[0032] like Fig.10As shown, it can be seen that a hole corresponding to the lock head 10 is provided on the housing 331, and the hole facilitates the lock head to enter the interior of the housing 331. The color difference ring is fixedly sleeved on the bottom end of the lock head 10. Because the position of the camera 334 is relatively fixed to the position of the housing 331, when the locking rod 7 is locked in the door, the position of the lock head 10 at the bottom end of the locking rod 7 in the interior of the housing 331 is also relatively fixed, so the interior of the housing 331 can be photographed by the camera 334. Because the position of the color difference ring is also relatively unchanged, when someone wants to open the door, the locking rod 7 must be rotated. At this time, the locking rod changes, and the position of the color difference ring in the interior of the housing 331 also changes. Because the surface of the color difference ring is evenly coated with a variety of different colors around the circumference, it can be judged through the photos taken by the camera. When the image comparison finds that the position of the color difference ring changes, an alarm is directly issued, and the locking system 3 on the vehicle is controlled to lock the vehicle, and when Fig.10 It can be seen that a horizontal plane is a cross section, and the downward top view projection of the lock head 10 is a rectangle, so the cross section of the lock head 10 is a rectangle.

[0033] like Figure 7-Figure 9 As shown, the locking block 32A3 is a cross-shaped structure, and the corresponding protrusions of the bottom receiving groove of the positioning block 13 are also cross-shaped structures evenly arranged axially, so the locking block 32A3 and the multiple protrusions in the receiving groove of the positioning block 13 form a mutually staggered canine structure.

[0034] Specific implementation process: Through the braking system locking unit, the carriage locking unit 32 and the box door locking unit 33 of the locking system, the vehicle's driving route, the opening and closing of the box door of the container 5 on the vehicle, and the locking of the box body of the container 5 and the vehicle body 11 can be remotely controlled with the cooperation of the program. When the vehicle deviates from the route, the braking system of the vehicle is directly locked through remote commands or internally set commands, and without remote commands, the door 6 of the container 5 cannot be opened manually, and the container 5 cannot be separated from the vehicle body 11, which greatly ensures the safety of the transported goods.

[0035] During actual use, the camera 334 needs to be set with a timer switch, and the timer switch also controls the fill light, so that the position of the color difference circle is photographed through the cooperation of the camera 334 and the fill light.
