As described above, in actual operation, the first battery 121 and the second battery 122 installed in the automated handling device 1 have a power value greater than the warning power value in an initial operating state, and the control module 14 is in the power state. After detecting the power of the first battery 121 and the second battery 122, the detection module 13 defines a higher battery in the first battery 121 and the second battery 122 as a high-power battery, and defines the other as a low-battery battery, and then the control module 14 uses the output control circuit 123 to control the high-battery battery to discharge at the first discharge speed, and control the low-battery battery to be larger than the first The second discharge speed of the discharge speed is discharged to avoid a gradual decrease in the power gap between the high-battery battery and the low-battery battery.

Then, when the low-battery battery is continuously discharged, the control module 14 detects that the low-battery battery is lower than the warning power value by the power detecting module 13, and the control module 14 uses the timing unit 142 to calculate the current command. The execution time difference between the execution time and the execution time of the next instruction execution time is further determined whether the instruction execution time difference is greater than the determination time interval stored by the storage unit 141. When the instruction execution time difference is greater than the determination time interval, the control module 14 The battery replacement demand signal S3 is transmitted to the battery exchange station 3 via the central host 2 via the carrier communication module 16.

After the automatic handling device 1 receives the permission to replace the battery signal, the control module 14 controls the driving module 11 to drive the automated handling device 1 to move to the battery exchange station 3, thereby causing the battery exchange station 3 to use the battery replacement module 34 to lower the battery. The battery is exchanged with the charging completion battery 311a.

On the other hand, when the battery exchange station 3 receives the battery replacement demand signal S3, and none of the plurality of batteries to be replaced has the charging completion battery 311a, the battery exchange station 3 sends a no-charge completion battery signal. The automatic handling device 1 is arranged to cause the control module 14 to further determine whether the amount of the high-power battery is lower than the warning power value. When it is determined that the power of the high-power battery is also lower than the warning power value, the control module 14 determines whether the difference between the current instruction execution time and the instruction execution time of the next instruction execution time is greater than the determination time interval. When it is judged that the amount of the high-battery battery is higher than the warning power amount, or the command execution time difference is smaller than the judgment time interval, the automatic handling device 1 continues to perform the carrying operation.

However, when the command execution time difference is greater than the judgment time interval, the control module 14 transmits the battery replacement demand signal S3 to the battery exchange station 3 again, and the battery exchange station 3 uses the charging module 31 to determine the plurality of batteries to be replaced again. Whether the charging completion battery 311a is included, and when it is determined that the charging completion battery 311a in the battery to be replaced is one, the low battery is preferentially exchanged with the charging completion battery 311a, and if the charging completion battery 311a is two or more, the battery is The exchange station 3 can simultaneously replace the high-battery battery and the low-battery battery with the charge-completed battery 311a.

As described above, the battery management method of the present invention mainly controls the first battery 121 and the second battery 122 provided in the automatic handling device 1, so that the discharge rate of the lower battery is faster than the higher battery, thereby effectively The power of the first battery 121 or the second battery 122 is prevented from being too close. Then, when the power of at least one of the first battery 121 or the second battery 122 is lower than the warning power value, the battery exchange station 3 is notified to replace the low battery. However, when the battery exchange station 3 does not have the battery 311a completed, it is detected whether the high-power battery with a higher power is lower than the warning power value, and then the automatic handling device is enabled when the high-power battery is lower than the warning power value. Automatic to battery exchange station 3 to replace low battery with High battery.

Please continue to refer to the third figure. The third figure shows the relative positional relationship between the automated handling device, the central host and the battery exchange station. As shown in the figure, in practical use, three battery exchange stations 3 (only one of which is shown) are disposed in a battery exchange area R1, and three automatic handling devices 1 (only one is shown) are located. A working area R2. Further, the center host 2 is electrically connected to the automated handling device 1 and the battery exchange station 3.

As described above, when the automated handling device 1 detects that the low-battery battery or the high-battery battery is lower than the warning power value, the automated handling device 1 sends the battery replacement demand signal S3 to the central host 2, and the central host 2 will again The battery replacement demand signal S3 is sent to the battery exchange station 3. However, when the plurality of battery exchange stations 3 return the rechargeable battery 311a, the central host 2 can be based on the position of the automated handling device 1 and each of the battery exchange stations 3. The position is to return the information of the battery exchange station 3 closest to the automated handling device 1 and having the charge-completed battery 311a to the automated handling device 1 so that the automated handling device 1 can move to the nearest battery exchange station 2 for battery exchange. In addition, in other embodiments, the automated handling device 1 can also be directly communicatively coupled to the battery exchange station 3 without centralized management through the central host 2.

In summary, since the automatic handling device in the prior art uses the uninterruptible power system to urgently supply power when the battery is dead, so that the automatic handling device can continue to perform the carrying work, or return to the charging station for charging, When the automatic handling device is charged, the handling work cannot be performed, which affects the overall working efficiency; in contrast, Since the battery management system provided by the present invention can control the discharge rate of the first battery and the second battery to be lower than the lower battery, the low battery can be discharged more quickly, and then the battery is low. When the battery's power is lower than the warning power value, ask the battery exchange station whether there is a battery that has been fully charged, and then exchange the low-power battery of the automatic handling device, so that the automatic handling device can effectively maintain the power for a long time, thereby enabling The automated handling device continuously performs the handling work.

The above is only a preferred embodiment of the present invention and does not impose any limitation on the present creation. Any person skilled in the art can make any form of equivalent replacement or modification to the technical means and technical content disclosed in the present invention without departing from the technical means of the present invention. The content is still within the scope of this creation.
