[0017] The present invention will be further described below with reference to specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the protection scope of the present invention.

[0018] The present utility model patent will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-4As shown, this utility model provides a warehouse safety detection system, including: a movable workbench 1, which is movably mounted on a track 10; an optical communication component 3, which is mounted on one side of the movable workbench 1 and electrically connected to a controller 2; and a detection component 4, which is mounted on the other side of the movable workbench 1 and electrically connected to the controller 2 or the optical communication component 3, for feeding back an electrical signal to the controller 2 or the optical communication component 3 when an obstruction is detected between the end point of the track 10 and the other side of the movable workbench 1.

[0020] Specifically, an optical communication component is installed on one side of the travel direction of the movable workbench 1. When personnel are performing maintenance work in the area on one side of the movable workbench 1, the communication path of the optical communication component 3 is blocked by the personnel. At this time, if the controller 2 sends a control signal to move the movable workbench 1, the optical communication component 3 cannot receive the control signal from the controller 2 because the communication path is interrupted. Therefore, the movable workbench 1 cannot be controlled by the controller to move, thus avoiding the risk of being bumped when someone is performing maintenance work in the area on one side. A detection component 4 is installed on the other side of the travel direction of the movable workbench 1. When personnel are performing maintenance work in the area on the other side of the movable workbench 1, the detection component 4 can detect the presence of personnel in the area and send an electrical signal to the optical communication component 3. The optical communication component 3 (with no obstructions on one side, allowing normal communication) then sends this electrical signal to the controller 2. Alternatively, a transmission line can be connected between the controller 2 and the detection component 4, allowing the feedback electrical signal to be sent directly to the controller 2. Upon receiving the electrical signal, the controller 2 sends a control signal to the optical communication component 3 to stop the movable workbench 1. If the movable workbench 1 has already been moved under the control of the controller before the maintenance personnel enter the area, it will stop moving upon receiving the control signal. If the optical communication component 3 receives the control signal from the controller 2 to move the movable workbench 1 after the maintenance personnel have entered the area, it will enter the moving state. However, if the detection component 4 still detects personnel at this time, it will send another control signal to stop the movable workbench 1, thus preventing the risk of collision when personnel are performing maintenance work in the other area.

[0021] It is worth noting that the movable workbench 1 moves on the track 10 inside the automated warehouse, and it consists of a movable chassis and a workbench. The workbench is equipped with ladders, detection devices and other equipment to assist personnel in positioning, placing or retrieving items.

[0022] In this embodiment, the optical communication component 3 includes an optical communication transmitter 5 and an optical communication receiver 6. The optical communication transmitter 5 is installed on one side of the movable workbench 1, and the optical communication receiver 6 is installed at the origin and electrically connected to the controller 2. The optical communication transmitter 5 and the optical communication receiver 6 are communicatively connected. The detection component 4 includes a detection transmitter 7 and a detection receiver 8. The detection transmitter 7 is installed on the other side of the movable workbench 1, and the detection receiver 8 is installed at the endpoint and electrically connected to the controller 2 or the optical communication transmitter 5.

[0023] When personnel enter one side of the area to carry out maintenance work, the communication signal emitted by the communication transmitter 5 is blocked by the maintenance personnel, and the communication receiver 6 cannot receive the control signal sent by the controller 2 to the communication transmitter 5, so it cannot control the movement of the movable workbench 1.

[0024] When personnel enter the other area (between the detector transmitter 7 and the detector receiver 8) for maintenance work, the light signal emitted by the detector transmitter 7 is blocked, and the detector receiver 8 cannot receive the light signal. This results in an electrical signal being generated and fed back to the communication transmitter 5, which then sends it to the communication receiver 6. The communication receiver 6 then sends it to the controller 2, or it can directly feed back to the controller 2. Upon receiving the electrical signal, the controller 2 sends a control signal to stop the movable workbench 1 from moving. This can, to a certain extent, prevent the occurrence of danger in the other area.

[0025] Those skilled in the art should understand that the controller 2 is a PC industrial computer; the start and stop control of the movement of the movable workbench 1 is implemented through the PC industrial computer.

[0026] Furthermore, it also includes an alarm 9, which is electrically connected to the detection receiver 8; when the detection receiver 8 generates an electrical signal, it also transmits the electrical signal to the alarm 9, and the alarm 9 sounds an alarm upon receiving the signal, serving to remind personnel. Those skilled in the art should understand that the alarm 9 can be an audible and visual alarm 9, emitting both sound and light as a reminder.

[0027] In this embodiment, preferably, the detection components are multiple units arranged horizontally at equal intervals; the multiple detection components 4 are arranged horizontally on the side of the movable workbench 1, so that they can cover the entire width of the movable workbench 1, effectively increasing the coverage area of ​​the detected area, so that even if the personnel are not between one set of transmitters and receivers, they can still block the other set of transmitters and receivers, effectively avoiding the occurrence of danger.

[0028] Furthermore, the distance between two adjacent detection components is 10cm-15cm; even further, the height of the detection components from the ground is 40cm-50cm; this distance and height are determined based on the relatively thin legs of humans, so that when a person enters between the two sets of detection components (even if they deviate from the waist position, the thickness of other positions such as the buttocks and abdomen will only be greater, so it is easier to cause obstruction in the above situation), the reception of the light signal can be successfully blocked, thereby triggering the movable workbench 1 to stop, which further improves the safety of personnel maintenance operations.

[0029] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. All technical solutions obtained by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the present invention.
