Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic flow chart of a battery pack transportation method according to an embodiment of the present invention, including:

s101: and acquiring a first drawing number of a battery pack on the AGV and a second drawing number of the real vehicle.

In this embodiment, acquiring the first drawing number of the battery pack on the AGV specifically includes: and acquiring a first code number on the battery pack, and acquiring the first drawing number according to the first code number.

In a specific embodiment, the first code number is a re-protection code number, and the re-protection code number may be a re-protection bar code or a re-protection two-dimensional code.

In this embodiment, the obtaining of the second drawing number of the real vehicle specifically includes:

acquiring a chassis number of a first real vehicle, and acquiring a chassis number of a corresponding real vehicle queue according to the chassis number of the first real vehicle;

and acquiring the second figure number corresponding to each real vehicle in the real vehicle queue according to the chassis number of the real vehicle queue.

In a specific embodiment, the first real vehicle locks the chassis number every day, then obtains the real vehicle queue according to the chassis number of the first real vehicle, then obtains the chassis number corresponding to the real vehicle queue, and obtains the second map number corresponding to each real vehicle through the chassis number of the real vehicle queue. The real vehicle queue is obtained through RFID collection when each real vehicle passes through the point position of the production line.

In this embodiment, the first drawing number is an actual part drawing number, and the second drawing number is a preset part drawing number required by the current real vehicle queue.

In a specific embodiment, the first figure number of the battery pack is acquired at a preset frequency, so that the response interval time between the first figure number and the second figure number can be ensured every time, and the problem that the battery pack is not matched with the real vehicle queue due to the fact that the first figure number is acquired quickly and repeatedly can be effectively avoided.

S102: when the first graph number and the second graph number are compared successfully, the battery pack is judged to be the battery pack required by the real vehicle, and then a first signal is sent to the AGV trolley, so that the AGV trolley transports the battery pack to a first destination and then loads the battery pack onto the real vehicle.

Wherein the first signal includes location information of the first destination.

In this embodiment, the first drawing number and the second drawing number are successfully compared, and it is determined that the battery pack is the battery pack required by the real vehicle, which means that the actual part is the preset part required by the current real vehicle queue. A first signal is sent to the AGV cart to cause the AGV cart to normally route the battery pack to a first destination. After the AGV trolley transports the battery pack to the first destination, the battery pack on the AGV trolley is loaded onto the real vehicle; therefore, after the comparison is successful, the AGV trolley smoothly sends the battery pack required by the real vehicle to the first destination, and the battery pack can be effectively and correctly loaded onto the corresponding real vehicle.

In this embodiment, the AGV transports the battery pack to a first destination, specifically:

when the first graph number and the second graph number are compared successfully, the battery pack is judged to be the battery pack required by the real vehicle, and then the first signal is sent to the AGV trolley, so that the AGV trolley transports the battery pack to the first destination after the position information of the first destination is compared successfully with the first preset position information. The first destination is the position of the corresponding real vehicle of the battery pack.

In this embodiment, on the basis that the first drawing number and the second drawing number are compared successfully, the position information of the first destination is compared with the first preset position information for verification, and the first preset position set by the AGV is matched with the position of the first destination where the real vehicle is located, so that the AGV can accurately send the battery pack required by the real vehicle to the position where the real vehicle is located, correct assembly is guaranteed, and the problem of wrong battery pack loading caused by deviation between the first preset position and the first destination position is avoided.

S103: when the comparison between the first graph number and the second graph number fails, the battery pack is judged to be not the battery pack required by the real vehicle, and then a second signal is sent to the AGV trolley so that the AGV trolley stops transporting the battery pack.

In this embodiment, when the comparison between the first drawing number and the second drawing number fails, the method further includes: after the AGV trolley stops running, when a chassis line detects that the battery pack is not loaded on the real vehicle, the chassis line stops running; wherein the chassis line is used for transporting the real vehicle.

Specifically, since the AGV stops transporting the battery pack, that is, the AGV stops running, the AGV cannot smoothly transport the battery pack to the first destination on time, and thus cannot load the battery pack onto the real vehicle at the first destination. Therefore, when the real vehicle is transported to pass through the first destination, the control module of the chassis line can detect whether the real vehicle is provided with the battery pack. When the control module of the chassis line detects that the real vehicle is not loaded with the battery pack, the assembly between the real vehicle and the battery pack is judged to be unsuccessful, and then the chassis line stops to stop transporting the real vehicle. In one embodiment, in addition to automatically detecting whether a battery pack is loaded on a real vehicle, the automatic detection method may also manually detect whether a battery pack is loaded on a real vehicle passing through a first destination; the manual detection of whether the battery pack is loaded on the real vehicle is a common technical means for those skilled in the art, and is not described herein again.

In this embodiment, when the comparison between the first and second numbers fails, the AGV is required to stop running and the chassis line is required to stop because:

if the AGV trolley is stopped, the chassis line continues to run, so that the AGV trolley successfully compared in the future continues to transport the battery pack to a corresponding destination, the queue sequence of the AGV trolleys is disturbed, the queue sequence of the AGV trolleys cannot correspond to the sequence of the real vehicle queue on the chassis line one by one, and the work order is further disturbed. If the battery pack is continuously transported by the AGV, the AGV cannot be conveniently searched by a worker and is subjected to manual exception handling. Therefore, when the comparison between the first drawing number and the second drawing number fails, the AGV trolley stops running and the chassis line stops, the mismatching of more battery packs caused by disordered trolley queues can be effectively avoided, and quick workers can find the trolley with the comparison error and perform corresponding manual exception handling.

In this embodiment, if the comparison between the first drawing number and the second drawing number fails, it is determined that the battery pack is not the battery pack required by the real vehicle, which means that the actual part is not the preset part required by the current real vehicle queue. Therefore, the AGV trolley is controlled to stop running so as to prevent the AGV trolley from sending a battery pack which is not needed by the real vehicle to a first destination and then mistakenly loading the battery pack on the real vehicle; meanwhile, the trolley with the comparison error can be conveniently found by the staff, corresponding manual exception handling is carried out, and the enterprise management cost is reduced.

In one embodiment, the AGV trolley stops after the first graph number and the second graph number fail to be compared. So a signal is sent to the management department so that the related staff can place the battery pack required by the real vehicle on the AGV trolley and then control the AGV trolley to recover the normal operation.

To further illustrate the battery pack transportation apparatus, please refer to fig. 2, fig. 2 is a schematic structural diagram of a battery pack transportation apparatus according to an embodiment of the present invention, including: an acquisition module 201 and a transportation module 202.

The obtaining module 201 is configured to obtain a first drawing number of the battery pack on the AGV and a second drawing number of the real AGV.

In this embodiment, the obtaining of the second drawing number of the real vehicle specifically includes:

acquiring a chassis number of a first real vehicle, and acquiring a chassis number of a corresponding real vehicle queue according to the chassis number of the first real vehicle;

and acquiring the second figure number corresponding to each real vehicle in the real vehicle queue according to the chassis number of the real vehicle queue.

The transportation module 202 is configured to, when the first graph number and the second graph number are successfully compared, determine that the battery pack is the battery pack required by the real vehicle, send a first signal to the AGV, so that the AGV transports the battery pack to a first destination and then loads the battery pack onto the real vehicle; when the first picture number and the second picture number fail to compare, judge the battery package is not the required battery package of real car, then to the AGV dolly sends the second signal, so that the AGV dolly stops transporting the battery package.

In this embodiment, the first signal includes location information of the first destination.

In this embodiment, when the comparison between the first drawing number and the second drawing number fails, the method further includes:

after the AGV trolley stops running, when a chassis line detects that the battery pack is not loaded on the real vehicle, the chassis line stops running; wherein the chassis line is used for transporting the real vehicle.

To better explain the battery pack transportation system, please refer to fig. 3, fig. 3 is a schematic composition diagram of a battery pack transportation system according to an embodiment of the present invention, including: AGV cart 301, chassis line 302, and battery pack transport 303.

when the control signal is the second signal, controlling the AGV trolley 301 to stop running; wherein the second signal is sent by the battery pack transport 303 to the AGV cart 301 when the comparison of the first and second image numbers fails.

In a specific embodiment, an IO board advtech ActiveDAQ Pro control (AdvAI) calling module is embedded in software of the AGV to realize control of the AGV. The embedding process specifically comprises the following steps: adding an AdvAI control in a tool box of the software of the AGV trolley through a specified path, and installing a Device Manager and a driver; linking the control on the software page form; and completing the configuration of the AdvAI control attributes and completing the calling module program of the AdvAI control port specifically called by different instructions of the software.
