Description

Technical Field

[0001] The embodiments of the present invention relate to express delivery technology, and in particular, to an express warehouse circuit. Background Art

[0002] Traditional express lockers show people a human-machine interaction panel in the middle and compartment lockers on the left and right. People go to the interaction panel to operate the compartment door, walk to the opened compartment to deposit or take out parcels, and close the door after depositing or taking out parcels. However, traditional express lockers can no longer meet people's current requirements for the intelligence and convenience of express lockers.

[0003] Express warehouses, which are like stereoscopic warehouses, have become a better choice. Their human-computer interaction panels are similar to express cabinets. The difference is that the storage and retrieval of items are not allocated to the slots, but the delivery and reception can be completed in front of the panel, that is, there is only one access port in front of the panel. When storing items, the access port is opened, and the express or items are placed on the access port tray. After that, the access port is closed, and the internal motion mechanism of the express warehouse will automatically transfer the express or items to the appropriate location. When picking up items, you only need to wait at the access port for a few seconds. The internal motion mechanism of the express warehouse will automatically transfer the express or items to the access port. After the access port door is opened, the express or items are taken away, and the access port is automatically closed. In addition, the internal sensors of the express cabinet can measure the weight and volume of the delivered items, allocate appropriate space, improve space utilization, and increase storage capacity.

[0004] Although express warehouses are more convenient and automated than express cabinets. However, the existing smart warehouses have complex internal mechanics, structures, and electrical systems, which are bound to fail and require maintenance. Therefore, express warehouses will have maintenance doors. Some maintenance doors are designed to be integrated with the front human-machine interaction panel, with only one door. This reduces costs, but is inconvenient for maintenance and will affect the electrical equipment of the interactive panel. To enter the express warehouse for maintenance, the entire interactive panel needs to be opened. During maintenance, the interactive function cannot work properly and lacks linkage. Only after the maintenance is completed can the panel maintenance door be closed for testing. The maintenance and repair of such express warehouses is very inconvenient. Summary of the invention

[0030] Embodiment 1

[0031] like Figure 1 As shown, a first embodiment of the present invention provides an express warehouse circuit, which includes a first power supply 100, a distribution box 200 and a working motor 300 connected in series in sequence.

[0032] Specifically, the express warehouse circuit also includes a main control board 400 and a maintenance gate circuit 500. The first power supply 100 provides a first working voltage to the working motor 300 of the express warehouse through the distribution box 200, and the distribution box 200 includes a first relay 210; the main control board 400 is used to provide a first control voltage to the first relay 210 to control the closing of the first relay 210 according to whether the first working voltage is received; the maintenance gate circuit 500 includes at least one travel switch, and the maintenance gate circuit 500 is connected in series between the first power supply 100 and the main control board 400, and the at least one travel switch is used to selectively provide the first working voltage to the main control board 400.

[0033] In this embodiment, the maintenance door circuit 500 includes two travel switches, namely, a first travel switch 510 and a second travel switch 520. Correspondingly, two maintenance doors are arranged on the left and right sides of the exterior of the express warehouse, which are electrically connected to the first travel switch 510 and the second travel switch 520, respectively. When the maintenance personnel opens any one of the maintenance doors, the corresponding travel switch will be disconnected, a short circuit will be formed between the first power supply 100 and the main control board 400, and the first working voltage will not be provided to the main control board 400. The main control board 400 stops providing the first control voltage to the first relay 210 according to the preset algorithm control, and the first relay 210 will be disconnected, and a short circuit will be formed between the first power supply 100 and the working motor 300, and the working motor 300 will stop working. In this way, the working motor 300 in the express warehouse will automatically stop working after the maintenance personnel opens the maintenance door, which facilitates the maintenance personnel to carry out maintenance work.

[0034] Furthermore, the express warehouse circuit also includes an emergency switch 600, a touch screen 700, an industrial computer 800 and a second power supply 110. The distribution box 200 also includes a second relay 220, which is connected in series between the first relay 210 and the working motor 300. The working motor 300 will work only when the second relay 220 receives the first working voltage. The touch screen 700 is the human-machine interaction panel on the express warehouse. The touch screen 700 is used to send a first control signal according to the user's operation on the touch screen 700; the industrial computer 800 includes a wireless communication module 810, which is used to receive a second control signal sent by the monitoring background 900. The industrial computer 800 is used to send a third control signal to the main control board 400 according to the first control signal and / or the second control signal, and the main control board 400 is used to provide the first control voltage to the first relay 210 according to the third control signal. The second power supply 110 is used to provide the second working voltage to the main control board, and the emergency switch 600 is connected in series between the first relay 210 and the second relay 220. The main control board 400 is connected in parallel between the emergency switch 600 and the second relay 220, and the first relay 210 is also used to provide the first working voltage to the main control board 400.

[0035] When the express warehouse is operating normally, the first working voltage provided by the first power supply 100 flows through the first relay 210 and the emergency switch 600, and then flows into the second relay 220 and the main control board 400, that is, the first relay 210 provides the first working voltage to the working motor 300 and the main control board 400. When the maintenance personnel may need the working motor 300 of the express warehouse to continue working after the maintenance door is opened in order to test the working condition of the express warehouse, the maintenance personnel can send a first control signal through the touch display screen 700, or request the monitoring background 900 to send a second control signal, and control the main control board 400 to continue to provide the first control voltage through the third control signal, so that the working motor 300 of the express warehouse continues to work. In addition, the main control board 400 is pre-set to stop providing the first control voltage if it does not receive the first working voltage provided by the first power supply 100 or the first working voltage provided by the first relay 210. When an emergency occurs, the maintenance personnel can press the emergency switch 600 to form a circuit break between the first relay 210 and the main control board 400, that is, the first relay 210 will stop providing the first working voltage to the main control board 400, and the main control board 400 will also stop providing the first control voltage to the first relay 210, the first relay 210 will be disconnected, and the working motor 300 will also stop working. Further, the main control board 400 is also used to control the wireless communication module 810 to send the first monitoring signal to the monitoring background 900 when the first working voltage is not received.

[0036] Optionally, the working motor 300 includes a servo motor 310, an AC motor 320, a stepper motor 330 and a push rod motor 340. The second relay 220 includes a DC relay 222 and an AC relay 221, wherein the DC relay 222 is used to provide a DC working voltage to the stepper motor 330 and the push rod motor 340 according to the first working voltage, and the AC relay 221 is used to provide an AC working voltage to the servo motor 310 and the AC motor 320 according to the first working voltage. The AC relay 221 is also connected to a 220V AC power supply 120. When the AC relay 221 receives the first working voltage, the AC relay 221 is closed, and the AC power supply 120 can provide an AC working voltage to the servo motor 310 and the AC motor 320. In this embodiment, the first working voltage is DC 24V, the first control voltage is DC 12V, the second working voltage is DC 12V, and the AC working voltage is AC 220V.

[0037] Preferably, the express warehouse circuit also includes a signal light (not shown in the figure), which is electrically connected to the main control board 400. When the main control board 400 does not receive the first working voltage, the signal light is controlled to go out to indicate maintenance personnel. The main control board 400 includes a third relay 430, a first photoelectric coupler 410 and a second photoelectric coupler 420. The first photoelectric coupler 410 is used to optically isolate the first working voltage from the first power supply 100, and the second photoelectric coupler 420 is used to optically isolate the first working voltage from the first relay 210 to achieve control of the signal light by the main control board 400. The third relay 430 is used to close according to the control of the main control board 400 to provide the first control voltage to the first relay 210.

[0038] For example, Figure 2 As shown, after the first working voltage VCC_24V is connected to the main control board, it is connected to the interface 1 of the first photoelectric coupler U1 after passing through the terminal CN1 and the resistor R2, the capacitor C1 is connected in parallel between the interface 1 and the resistor R2 and grounded, the interface 2 of the first photoelectric coupler U1 is connected in parallel between the capacitor C1 and the ground wire, and the second working voltage is converted to provide the third working voltage VCC_3V3 to the signal light LED1, that is, the third working voltage is 3.3V, and the third working voltage VCC_3V3 flows into the signal light LED1 after passing through the resistor R1 and the resistor R3, the interface 4 of the first photoelectric coupler U1 is connected in parallel between the resistor R1 and the resistor R3, the signal light LED1 is grounded, and the interface 3 of the first photoelectric coupler U1 is connected in parallel between the signal light LED1 and the ground wire. When the first working voltage is present, the paths between interface 3 and interface 4 of the first photocoupler U1 are disconnected through the optical coupling isolation of the first photocoupler U1, and the third working voltage VCC_3V3 flows into the signal light LED1, and the signal light LED1 lights up. When the first working voltage is not present, the third working voltage VCC_3V3 passes through interface 3 and interface 4 and is grounded, and the signal light LED1 does not light up.
