Each of the above-described devices is used in cooperation with the related devices and control system inside the housing 1 of the logistics object container.
Referring to fig. 2, a schematic diagram of an internal structure of a logistics object container provided in a first embodiment of the present application is shown. The logistics object container provided in the first embodiment of the application further comprises a multilayer logistics object placing area 201 arranged inside the shell 1 except for the shell 1, and the logistics object placing area 201 is distributed or uniformly distributed on two sides inside the shell 1.

In daily life, common logistics object container is the goods from carrying the cabinet or the express delivery is from carrying the cabinet, and at this moment, the logistics object just is goods or express delivery parcel respectively. Specifically, in the first embodiment of the present application, an express self-service delivery cabinet is taken as an example to describe the logistics object container provided in the first embodiment of the present application.

Since it is a conventional technical means to control the relevant equipment to operate through the controller, it is not described here. The motor 205 is a motor having a lifting function, and can enable the transmission device 203 to have a lifting function, and when the transmission controller 204 sends a lifting or lowering command to the rear motor 205, the motor 205 can drive the transmission device 203 to lift to a specified position.
Referring to fig. 3, a schematic diagram of a robot arm structure provided in an embodiment of the present application is shown. A robot 300 is disposed on the logistics transfer platform 206, and the robot 300 includes a telescoping mechanism 301 and a manipulator 302. After receiving the instruction to acquire the package, the transmission controller 204 will first send a lifting instruction to the transmission device 203, and after the transmission device 203 is lifted to a designated position, the transmission controller 204 will further send a grabbing instruction to the robot 300.

It should be noted that, in order to prevent the express packages from slipping off the logistics transfer platform 206, the shielding pieces 303 may be disposed on the left and right sides of the logistics transfer platform 206. The robot arm 300 is further provided with an extension stopper 304 and a contraction stopper 305 for limiting the extension distance of the extension mechanism 301.

When the manipulator 302 places the grasped express package on the logistics transfer platform 206, the transmission controller 204 sends a descending instruction to the transmission device 203, and controls the transmission device 203 to descend to the logistics object access opening 102. In this way, the relevant personnel can obtain the express package at the logistics object access opening 102. The principle of placing the express package in the storage compartment 202 is similar to the principle of obtaining the express package from the storage compartment 202, and will not be described in detail here. However, it should be noted that before the express package is placed in the storage compartment 202, the size specification of the express package needs to be determined, and then the express package needs to be reasonably allocated to the storage compartment 202 with the corresponding size specification.
Referring to fig. 4, a schematic diagram of a measurement grating configuration provided in a first embodiment of the present application is shown. The express delivery self-service cabinet that provides in this application embodiment one still is provided with measurement grating 106 on its casing 1, and measurement grating 106 sets up on the left side of the human-computer interaction display screen for measure the size and specification of express delivery parcel.

Specifically, after the relevant person inputs or selects a corresponding instruction on the human-computer interaction display screen 101, the human-computer interaction interface can send the corresponding instruction to the respective controller in the above devices through the computer control system, so as to control the devices to execute the input or selection of the corresponding instruction on the human-computer interaction display screen 101 by the relevant person. Man-machine interaction technology is now widely used and will not be described in detail here.
When the related personnel obtains the logistics objects in the logistics object container or stores the logistics objects in the logistics object container, the logistics object access port 102 is needed to be passed through. Referring to fig. 5, a schematic diagram of a control circuit link provided in a first embodiment of the present application is shown. In order to ensure the safety of the logistics objects, the interaction window 501 capable of being automatically opened and closed is arranged on the logistics object access port 102, and when the related personnel access the logistics objects, the closed interaction window 501 in the logistics object container needs to be controlled to be automatically opened first, and then the logistics objects can be obtained from the logistics object container or stored in the logistics object container. After the storing or retrieving operation is completed, the interactive window 501 is automatically closed. However, when the interactive window 501 is automatically closed, personal safety problems such as pinching and the like often occur. Therefore, in order to prevent the similar situation from occurring, in the first embodiment of the present application, a control circuit for controlling the interactive window 501 to open or close is provided, so as to control to keep opening in the state that the interactive window 501 is already opened during the automatic closing process, or stop closing and re-open during the automatic closing process of the interactive window 501, or directly automatically close the interactive window 501. In order to distinguish the opening of the closed interactive window 501, and the interactive window 501 is kept open in the state that the interactive window 501 is already opened, or in the process that the interactive window 501 is automatically closed, the closing is stopped and the opening is performed again, and the opening of the interactive window 501 in the originally closed state is called as opening.
The control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application includes: a controller 502 and at least two signal output units 503 connected to the controller. Wherein, the signal output unit is used for sending a control signal for instructing to open or close the interactive window 501 in the logistics object container to the controller 502. The controller 502 is configured to control the interactive window 501 to open or close according to control signals sent by at least two signal output units 503.
It should be noted that the interactive window 501 is provided with a movable fan 504 which can move back and forth, left and right, or up and down, and the opening or closing of the interactive window 501 is actually realized by the movement of the movable fan 504. In the first embodiment of the present application, an interactive window 501 provided with a movable fan 504 capable of moving up and down is specifically taken as an example, and a detailed description is given of a control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application. Here, the interactive window 501 may be set in advance to be closed when the active fan 504 moves downward, and to be opened when the active fan 504 moves upward. Of course, the reverse arrangement is also possible.
When the control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application is provided, the controller 502 and the different signal output units 503 need to be connected in series, and each form an independent control link. The signal output unit 503 in each control link individually sends a control signal for instructing to open or close the interactive window 501 in the logistics object container to the controller 502. The control circuit provided in the first embodiment of the present application must include a controller 502 and at least two signal output units 503 connected to the controller 502. That is, the control circuit must include two or more control links. The signal output unit 503 in each control link individually sends a control signal to the controller 502 for instructing to open or close the interactive window 501 in the physical distribution object container, and simultaneously acts on the controller 502, and then the controller 502 is used for controlling the interactive window 501 to open or close according to all the control signals received by the controller 502.
Since the controller 502 is connected with at least two signal output units 503, each signal output unit 503 can form a separate control link with the controller 502. In this way, the control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application can simultaneously control the opening or closing of the interactive window 501 through a plurality of control links. Therefore, the link redundancy of the control circuit is increased, the plurality of control links control the opening or closing of the interactive window simultaneously, the fault tolerance rate and the stability of the control circuit can be increased, the link redundancy of the control circuit for controlling the opening or closing of the interactive window 501 is further improved, and the safety and the reliability of the opening or closing control of the interactive window 501 are improved.
The control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application includes, in the at least two signal output units 503, at least one first signal output unit 505, where the first signal output unit 505 is an object sensor, and the object sensor generates the control signal by sensing whether there is an object in the safety control range of the interactive window 501, and sends the control signal to the controller 502. That is, the control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application may all be the first signal output unit 505, or only one first signal output unit 505 may be provided, and then, the remaining signal output units 503 are the non-body sensor type signal output units 503.
It should be noted that, if the object sensor senses that an object exists in the safety control range of the interactive window 501, a control signal for instructing to open the interactive window 501 (the movable fan 504 moves upward) is generated; alternatively, the object sensor generates a control signal for instructing to close the interactive window 501 (the movable fan 504 moves down) if it senses that there is no object within the safety control range of the interactive window 501. Among them, the object sensor is preferably an infrared sensor. Because infrared sensor is convenient for install, when generating the sensing signal, directly whether there is relevant operating personnel through the response moreover, so, to preventing that operating personnel from appearing the incident such as tong, compare in other object inductors more effectively.
Of course, the object sensor may also be a gravity sensor. At this time, the gravity sensor needs to be installed on the logistics transportation platform 206 for sensing whether the logistics transportation platform 206 has extra gravity to determine whether the logistics object on the logistics transportation platform 206 has been taken away, if the gravity sensor determines that the logistics object has not been taken away, it is determined that an object exists within the safety control range of the interactive window 501, and a control signal for instructing to open the interactive window 501 (the movable fan 504 moves upward) is generated. Otherwise, it is considered that there is no object within the safety control range of the interactive window 501, and a control signal for instructing to close the interactive window 501 (the movable fan 504 moves down) is generated. Of course, when there are two or more object sensors in the at least two signal output units 503, all of the object sensors may be infrared sensors or gravity sensors, or both of the object sensors may exist.
Although there are various types of object sensors, the sensing principle of the various types of object sensors is mostly similar, that is, by sensing whether there is an object within the safety control range of the interactive window 501, a control signal is generated and sent to the controller 502. If the types of the signal output units 503 in all the control links in the control circuit are all the same, although the link redundancy of the control circuit can be improved, the execution mode of the control links of the control circuit is single, and therefore, the safety and reliability of the control circuit for controlling the opening or closing of the interactive window 501 cannot be well guaranteed. In order to better ensure the safety and reliability of the control circuit for opening or closing the interactive window 501. The control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application further includes at least one second signal output unit 506 in the at least two signal output units 503, where the second signal output unit 506 is configured to generate a control signal according to a current of the driving device 507 and send the control signal to the controller 502, and the driving device 507 is configured to drive a gate (i.e., a movable fan 504) of the interactive window 501 to open or close.
Since the drive device 507 controls the movement of the active fan 504 to be blocked, the current flowing through the drive device 507 is different from the current flowing through the active fan 504 when the movement of the active fan 504 is normal. Therefore, the second signal output unit 506 is used for generating a control signal according to the current of the driving device 507 to determine whether the movement of the active fan 504 is blocked, and sending the control signal to the controller 502.
Referring to fig. 6, a schematic diagram of a current collection of a control circuit according to a first embodiment of the present application is shown. The second signal output unit 506 includes a current collecting subunit 508 and a voltage converting subunit 509. The collecting end of the current collecting subunit 508 is connected to the output end of the driving device 507, the output end of the current collecting subunit 508 is connected to the input end of the voltage converting subunit 509, and the output end of the voltage converting subunit 509 is connected to an input end of the controller 502. Specifically, the current collecting subunit 508 is configured to collect current passing through the driving device 507, and the voltage converting subunit 509 is configured to convert the current collected by the current collecting subunit 508 into a voltage value, and generate a control signal according to the voltage value and send the control signal to the controller 501.
It should be noted that, in the control circuit for controlling the opening or closing of the interactive window provided in the first embodiment of the present application, the voltage conversion subunit 509 is used to convert the acquired current of the current acquisition subunit 508 into a voltage value, in such a manner that the current acquisition subunit 508 is set as a resistor, and the resistor is connected in series with the driving device 507, at this time, the current flowing through the resistor is the current of the driving device 507. Then, the voltage value across the resistor is measured by using the voltage conversion subunit 509, so that the current collected by the current collection subunit 508 can be converted into a voltage value.
Before converting the current collected by the current collecting subunit 508 into a voltage value, a voltage threshold needs to be preset according to the operation condition of the driving device 507, and when the voltage value converted by the voltage converting subunit 509 exceeds the preset voltage threshold, a control signal for instructing to open the interactive window is generated; alternatively, the voltage value converted by the voltage conversion sub-unit 509 does not exceed the preset voltage threshold, and then a control signal for instructing to close the interactive window is generated.

Finally, the voltage conversion sub-unit 509 is connected in series with the controller to form a current control link. When the voltage value converted by the voltage conversion sub-unit 509 exceeds a preset voltage threshold, the signal "1" is output, otherwise, the signal "0" is input. When both control links send out a "0" signal, the control signal sent by the controller 501 for instructing to close the interactive window 504 is denoted as "0", and at this time, the active fan 504 is closed. Otherwise, the control signal sent by the controller 501 for instructing to open the interactive window 504 is recorded as "1", and at this time, the active fan 504 is opened.

Specifically, when the controller 501 sends a control signal (signal "1") for instructing to open the interactive window 504, the driving control unit controls the driving device 507 to rotate clockwise, and at this time, the movable fan 504 is opened. When the controller sends a control signal (signal '0') for instructing the switch to close the interactive window 504, the driving control unit controls the driving device 507 to rotate counterclockwise, and at this time, the movable fan 504 is closed. Wherein, the drive control unit is an H-bridge drive chip.
