Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent storage, in particular to an intelligent shelf system and an electronic warehouse. BACKGROUND

[0002] With the development of manufacturing and transportation industry, as a key link to improve the efficiency of manufacturing and transportation, the traditional warehouse adopts manual picking, and the electronic material needs manual picking, which is low in efficiency, large in labor demand and prone to errors. In order to reduce labor cost, enterprises use intelligent shelves to reduce labor demand. The current intelligent shelves use LED (Light Emitting Diode) indicator lights and two-dimensional code positioning to assist picking, but the indicator light does not have the function of detecting whether the indication of the LED indicator light is correct in the process of assisting picking. If individual LED lights fail, it is easy to cause the situation of missing goods. At the same time, the two-dimensional code positioning auxiliary picking increases the photoelectric detection system. This local detection system needs to configure photoelectric transceiver diodes for each storage position and use multiple MCU processors to detect the tray, which leads to complex system control and high hardware cost. SUMMARY

[0003] To solve the above technical problems, the present application provides an intelligent shelf system and an electronic warehouse, which at least solve one of the above problems.

[0004] The first aspect of the present application provides an intelligent shelf system, which comprises at least one shelf, a controller and a plurality of indicator lights. Each shelf comprises at least one storage position, and each storage position is provided with one indicator light. The plurality of indicator lights are divided into a plurality of groups, and the signal transmission between each indicator light in each group is in a serial manner. The two ends of each group are connected with the controller. The controller is used to control the indicator light corresponding to the storage position where the corresponding material is stored to light up after receiving the material demand instruction, and receive the feedback signal of the state of the circuit where the indicator light is located. The state of the circuit where the indicator light is located includes normal and fault.

[0005] The second aspect of the present application provides an electronic warehouse, which comprises a server and the above intelligent shelf system. The shelves are connected through connection lines, and the server is connected with a production management system. The server is used to receive the instructions sent by the production management system and transmit them to the intelligent shelf system, and receive the material information and / or shelf state in the intelligent shelf system.

[0006] The intelligent shelf system and the electronic warehouse provided by the application, since each group of indicator lights transmits signals in a serial manner, when the circuit where the group of indicator lights is located fails, the controller cannot receive feedback signals, at this time, the controller sends a failure warning to a reminding device, thereby avoiding the situation that the staff do not know that the circuit where the group of indicator lights is located fails and cause the goods to be missed; meanwhile, since the interconnection and intercommunication between the production management system and the intelligent shelf are realized through the server, it is not necessary to set up a photoelectric detection system and multiple MCU processors, thereby reducing the complexity of system control and the hardware cost.

Those skilled in the art can understand the specific meaning of the above-mentioned term in the application according to the specific circumstances.

[0014] Please refer to Figure 1 , Figure 1 The structural schematic diagram of the electronic warehouse provided by an embodiment of the present application is shown.

[0015] As Figure 1 shown, in an embodiment, the electronic warehouse 1 comprises a server 2 and a smart shelf system 3; the smart shelf system 3 comprises at least one shelf 30. The shelves 30 are connected through connection lines 4 between the shelves 30 and between the shelves 30 and the server 2. The server 2 is connected with a MES system 5 (Manufacturing Execution System, production management system). The server 2 is used to receive the instructions sent by the production management system 5 and transmit them to the smart shelf system 3, and receive the material information and / or the shelf state in the smart shelf system 3.

[0016] In the embodiment, the interconnection and intercommunication between the MES system 5 and the smart shelf 30 are realized through the server 2, so it is not necessary to set up an optoelectronic detection system and a plurality of MCUs (Microcontroller Unit, single-chip microcomputer) to control the smart shelf system 3 and obtain the material information and / or the shelf state in the smart shelf system 3, thus reducing the control complexity of the smart shelf system 3 and the hardware cost.

[0017] Among them, the connection relationship between the server 2 and the MES system 5 can adopt wired connection, or wireless connection such as WIFI connection, RJ45 Ethernet connection, etc.

[0018] Specifically, the MES system 5 is a software system, which is operated through a smart terminal, which can be but is not limited to a tablet.

[0019] Specifically, in an embodiment, the server 2 can adopt an edge server, which is configured as an ARM Cortex-A55 CPU, a 4+32GB memory mainboard, a Linux system, and a structure size of 150mmx102mmx22mm, etc. It can be understood that in other embodiments, other configurations of edge servers can be adopted, which are not limited to the configurations exemplified in the embodiment. The edge server is configured with two RS485 modules, RS485 is a commonly used communication standard in the industry, which can connect two groups of RS485 networks to realize redundancy. Compared with the traditional X86 computer as the server in the prior art, the edge server is small in size, low in power consumption, and cheap in price, and does not need to be placed in a remote computer room.

[0020] Further, in an embodiment, the server 2 is arranged in the shelf 30. It can be understood that in other embodiments, the server 2 can also not be arranged in the shelf 30, but arranged in the same electronic warehouse 1 independently of the smart shelf system 3.

[0021] Please refer to the accompanying drawings Figure 2 , Figure 2 The structural block diagram of the smart shelf system provided in an embodiment of the present application is shown.

[0022] As Figure 2 shown, further, in an embodiment, the smart shelf system 3 comprises a communication module 35; the communication module 35 is used for connecting communication with the server 2, the communication module 35 is used for receiving the instruction sent by the server 2, and sending the material information and the shelf state in the shelf 30 to the server 2.

[0023] Specifically, the smart shelf system 3 comprises a plurality of shelves 30, and each shelf 30 is provided with a communication module 35, the communication module 35 comprises an RS485 controller 31, an RS485 input interface 352 and an RS485 output interface 353, the connection line 4 can adopt but is not limited to RS485 bus, the connection line 4 has a plurality of roots, and the shelves 30 are connected in series in a daisy chain type between the shelves 30 and between the shelf 30 and the server 2, that is, one end of the first connection line 40 is connected to the server 2, and the other end is connected to the RS485 input interface of the first shelf, one end of the second connection line 40 is connected to the RS485 output interface of the first shelf, and the other end is connected to the RS485 input interface of the second shelf, and the connection is sequentially connected until one end of the last connection line 40 is connected to the last shelf 30, and the other end is connected to the server 2.

[0024] Specifically, each shelf 30 comprises at least one storage layer 301, and usually a plurality of storage layers 301.

[0025] Please refer to the accompanying drawings Figure 1 and Figure 2 , in an embodiment, the smart shelf system 3 comprises at least one shelf 30, a controller 31 and a plurality of indicator lights 32; each shelf 30 comprises at least one storage position 302, each storage position 302 is provided with one indicator light 3201, the plurality of indicator lights 32 are divided into a plurality of indicator light groups 320, and each indicator light group 320 is connected to the controller 31 at both ends in a serial manner; the controller 31 is used for controlling the indicator light 3201 corresponding to the storage position 302 storing the corresponding material to be on and controlling the indicator light 3201 corresponding to the storage position 302 storing the corresponding material to be bright after receiving the material demand instruction, and receiving the feedback signal of the state of the circuit where the indicator light 3201 is located; wherein, the state comprises normal and fault.

[0026] In this embodiment, since the signal transmission between the indicator lights 3201 in each indicator light group 320 is in a serial manner, when the circuit where the indicator light group 320 is located fails, the controller 31 cannot receive the feedback signal, at this time, the controller 31 will send a failure warning to a reminding device, so as to avoid the situation that the staff does not know that the circuit where the indicator light group 320 is located fails, and causes the goods to be missed.

[0027] In this embodiment, since the signal transmission between the indicator lights 3201 in each indicator light group 320 is in a serial manner, when the circuit where the indicator light group 320 is located fails, the controller 31 cannot receive the feedback signal, at this time, the controller 31 will send a failure warning to a reminding device, so as to avoid the situation that the staff does not know that the circuit where the indicator light group 320 is located fails, and causes the goods to be missed.

[0028] In this embodiment, since the signal transmission between the indicator lights 3201 in each indicator light group 320 is in a serial manner, when the circuit where the indicator light group 320 is located fails, the controller 31 cannot receive the feedback signal, at this time, the controller 31 will send a failure warning to a reminding device, so as to avoid the situation that the staff does not know that the circuit where the indicator light group 320 is located fails, and causes the goods to be missed.

[0029] In this embodiment, since the signal transmission between the indicator lights 3201 in each indicator light group 320 is in a serial manner, when the circuit where the indicator light group 320 is located fails, the controller 31 cannot receive the feedback signal, at this time, the controller 31 will send a failure warning to a reminding device, so as to avoid the situation that the staff does not know that the circuit where the indicator light group 320 is located fails, and causes the goods to be missed.

[0030] Specifically, each shelf 30 comprises at least one storage layer 301, each storage layer 301 comprises at least one storage position 302, and each storage position 302 is provided with one indicator light 3201. A plurality of indicator lights 32 corresponding to the storage positions 302 of each storage layer 301 are divided into a plurality of large groups, i.e., one indicator light large group 320 corresponding to one storage layer 301. For example, one shelf 30 has 7 storage layers 301, each storage layer 301 has 200 storage positions 302, and there should be 1400 indicator lights 3201 in total, which are divided into 7 large groups, each large group having 200 indicator lights 3201 (the number is only for illustration). All the indicator lights 3201 in each large group are connected in series for signal transmission, and the two ends of each indicator light large group 320 are connected to the controller 31 through the connectors 33. By dividing the plurality of indicator lights 32 into a plurality of large groups and connecting the indicator lights 320 at the two ends of each large group to the two ends of the controller 31, the refresh speed of signal transmission can be improved compared with connecting the two ends of the plurality of indicator lights 32 to the two ends of the controller 31 without grouping. It can be understood that in other embodiments, the plurality of indicator lights 32 can also be grouped without being divided into one indicator light large group 320 corresponding to each storage layer 301, which is not limited here.

[0031] In one embodiment, the circuit connections of the indicator lights 3201 in each indicator light large group 320 are connected in parallel; the signal output end of the controller 31 is connected to the starting indicator light 3201a in one indicator light large group 320 through the first end connector 331, and the signal input end of the controller 31 is connected to the end indicator light 3201z in the indicator light large group 320 through the end connector 332; the first power supply (not marked) is connected in parallel across the two ends of the first end connector 331, and the second power supply (not marked) is connected in parallel across the two ends of the end connector 332.

[0032] Specifically, the controller 31 includes a plurality of GPIO ports (General Porpose Input Output), which can be controlled by software to be input ports or output ports. Since the two ends of each group of indicator lights 320 are connected with the controller 31, when the indicator lights 32 are divided into 7 groups, the controller 31 includes at least 14 GPIO ports, at least 7 output ports, and at least 7 input ports. Correspondingly, when the indicator lights 32 are divided into M groups, the controller 31 includes at least 2M GPIO ports. Further, the head connector 331 includes a first connector 3310 and a second connector 3311, the output ports of the controller 31 are connected with the first connector 3310, the tail connector 332 includes a third connector 3320 and a fourth connector 3321; the first connector 3310 is connected with the second connector 3311 through a three-wire cable, the second connector 3311 is connected with the starting indicator light 3201a in the large group of indicator lights 320, the last indicator light 3201z in the large group of indicator lights 320 is connected with the third connector 3320, the third connector 3320 is connected with the fourth connector 3321 through a three-wire cable, and the fourth connector 3321 is connected with the input ports of the controller 31, thereby forming a signal closed-loop feedback. After receiving the material demand instruction, the controller 31 controls the corresponding indicator light 3201 of the storage location 302 where the corresponding material is stored to light up, and receives the feedback signal of the state of the circuit where the indicator light 3201 is located. One of the three-wire cables is a data line for transmitting signals, and the other two are power supply lines, one of which is connected with the positive electrode and the other of which is connected with the negative electrode.

[0033] Specifically, the controller 31, the first connector 3310 and the fourth connector 3321 can be located on the same mainboard, the mainboard is powered by a power supply, and the two pins of the first connector 3310 and the two pins of the fourth connector 3321 are connected in parallel on the mainboard. Therefore, the first power supply and the second power supply can be the same power-on mainboard. It can be understood that in other embodiments, the first power supply and the second power supply can also be different power-on mainboards or different directly powered power supplies.

[0034] It can be understood that the "first end connector 331 is connected with the first power supply at both ends, and the tail connector 332 is connected with the second power supply at both ends" actually means that the first connector 3310 in the first end connector 331 is directly connected in parallel with the first power supply, and the fourth connector 3321 in the tail connector 332 is directly connected in parallel with the second power supply; the first connector 3310, the second connector 3311 and the third connector 3320 are indirectly connected in parallel with the second power supply; and the second connector 3311, the third connector 3320 and the fourth connector 3321 are indirectly connected in parallel with the first power supply.

[0035] Since the power supply circuits between the indicator lights 3201 in the indicator light group 320 are connected in parallel, and when the number of indicator lights 3201 in the indicator light group 320 is large, for example, one indicator light group 320 has 200 (the number is an example) indicator lights 3201, the circuit must be longer, if there is only one power supply in the entire power supply circuit, the voltage drop in the circuit will be larger, therefore, the voltage drop at the indicator light 3201 far away from the power supply in the circuit of one indicator light group 320 is larger, which can easily cause the indicator light 3201 far away from the power supply to not work normally, therefore, by connecting the two pins of the first connector 3310 and the two pins of the fourth connector 3321 in parallel on the mainboard, the problem of voltage drop at the end of the circuit is solved by double power supply, and the reliability of the intelligent shelf system 3 is further improved.

[0036] Further, in an embodiment, when the indicator light group 320 set on one layer of storage layer 301 is relatively long, each indicator light group 320 is further divided into a plurality of indicator light groups (not marked), for example, 200 indicator lights 3201 are set on one layer of storage layer 301, which can be divided into 8 indicator light groups, each group has 25 indicator lights 3201, which is more convenient for production and manufacturing. Among them, the indicator lights 3201 in each group are arranged on a circuit board (the circuit board can be a PCB board or an FPC board), and each circuit board is provided with a connector 33, and the two connectors 33 are connected by a three-wire cable.

[0037] In an embodiment, the controller 31 controls the brightness, extinction and display color of each indicator light 3201 in an indicator light group 320 by sending 24xN+n bit data, and simultaneously detects whether the circuit where the indicator light group 320 is located is normal; wherein N is the number of indicator lights in the indicator light group 320, and n is a positive integer. For example: one indicator light group 320 has 200 indicator lights 3201, then the controller 31 controls the brightness, extinction and display color of each indicator light 3201 in an indicator light group 320 by sending 24x201 bit data, and simultaneously detects whether the circuit where the indicator light group 320 is located is normal (the data is only an example).

[0038] Further, each indicator light 3201 extracts 24-bit data controlling its brightness, extinction and display color in turn, and the 24xN+n-bit data is read by the indicator light group, and the last n-bit data is read by the controller 31 to determine whether the circuit where the indicator light group 320 is located is normal. It can be understood that the 24-bit data is extracted by each indicator light 3201, and then 24-bit data is less. For example, an indicator light group 320 has 200 indicator lights 3201, and the controller 31 controls the brightness, extinction and display color of each indicator light 3201 in the indicator light group 320 by sending 24x200+n-bit data. When the 24x201-bit data is transmitted to the starting indicator light 3201a in the group, the starting indicator light 3201a extracts 24-bit data to the data latch in the driving chip, and the remaining 24x200-bit data is transmitted to the next indicator light 3201 after being processed in the chip. After the last indicator light 3201 extracts the data, there are still n-bit data, which are transmitted from the input port of the controller 31 to the controller 31. When the controller 31 can receive the n-bit data, it indicates that the circuit where the indicator light group 320 is located is normal. When the controller 31 does not receive the n-bit data, it indicates that the circuit where the indicator light group 320 is located is faulty.

[0039] Specifically, the n-bit data can be 24-bit data.

[0040] Please refer to Figure 2 With Figure 3 , Figure 3 A schematic diagram for controlling the display color of the indicator light by 24-bit data.

[0041] As Figure 3 shown, in the 24-bit data, every 8 bits correspond to control R, G, B three primary colors. For example, when you want to control an indicator light to display red, R7~R0 is high, G7~G0 is low, and B7~B0 is low. Then the indicator light 3201 is lit in red. By adjusting the control data bits of RGB three primary colors, the indicator light 3201 can display different colors, such as red, orange, green, blue, etc.

[0042] In an embodiment, the brightness and extinction of the indicator light 3201 are controlled by using unipolar return-to-zero code. The unipolar return-to-zero code means that when a "1" code is sent, i.e. high level, a positive current is sent to control the indicator light 3201 to be bright; when a "0" code is sent, i.e. low level, no current is sent, and the indicator light 3201 is extinguished.

[0043] In an embodiment, the controller 31 is further configured to control the indicator lights 3201 corresponding to the storage locations storing the materials required by the same project to display the same color, and control the indicator lights 3201 corresponding to the storage locations storing the materials required by different projects to display different colors, after receiving the material requirements of multiple projects at the same time.

[0044] For example, project A requires materials A1, A2 and A3, project B requires materials B1, B2, B3 and B4, and project C requires materials C1, C2 and C3. The controller 31 controls the indicator lights 3201 corresponding to the storage locations storing A1, A2 and A3 to display green, controls the indicator lights 3201 corresponding to the storage locations storing B1, B2, B3 and B4 to display red, and controls the indicator lights 3201 corresponding to the storage locations storing C1, C2 and C3 to display blue. The staff can take the materials of the three projects at the same time, for example, the staff holds three boxes, one box for each project, and selects the shortest path to take the materials according to the indication of the indicator lights 3201. The staff sees the storage locations with bright green, red and blue lights and puts the materials in the storage locations into different boxes. Compared with the indicator lights that can only display one color, the staff can only take the materials of one project at a time, for example, the staff first takes the materials of project A according to the indicator lights 3201, and then needs to go back to take the materials of project B, and then goes back to take the materials of project C. The staff needs to go back and forth repeatedly, which wastes a lot of time. Therefore, in this embodiment, the controller 31 controls the indicator lights 3201 corresponding to the storage locations storing the materials required by the same project to display the same color, and controls the indicator lights 3201 corresponding to the storage locations storing the materials required by different projects to display different colors, so that the staff can take the materials of multiple projects at the same time, and the work efficiency is improved.

[0045] Please refer to Figure 4 , Figure 4 The structural schematic diagram of the intelligent shelf system provided in another embodiment of the present application.

[0046] In another embodiment, the intelligent shelf system 3 further comprises warning lights 34, the warning lights 34 are arranged on the shelf 30, the controller 31 is electrically connected with the warning lights 34, and the controller 31 is configured to control the warning lights 34 corresponding to the shelf 30 storing the corresponding materials to light up after receiving the material requirement instruction.

[0047] Specifically, the warning lights 34 can be arranged at the top of the shelf 30, so that the staff can easily see them. In other embodiments, the warning lights 34 can also be arranged at the side of the storage layer 301 at a high position in the shelf 30.

[0048] Since there are generally many shelves 30 in the electronic warehouse 1, and the indicating light 3201 is arranged at the storage site 302, the staff cannot see the indicating light 3201 at a glance, therefore, by arranging the warning light 34 and arranging the warning light 34 at the top of the shelf 30, the staff can see the warning light 34 at a glance, and after finding the shelf corresponding to the warning light 34, the staff can find the required material according to the indicating light 3201, which is more convenient and fast.

[0049] In another embodiment, the warning light 34 is used to flash when the shelf 30 where the warning light 34 is located has a fault other than the fault of the warning light 34 itself, to alert the staff that the shelf 30 has a fault. Specifically, different colors can be used for flashing according to different fault locations.

[0050] For example, the warning light 34 is used to flash when the indicating light 3201 on the same shelf 30 as the warning light 34 has a fault, and the indicating light 3201 flashes in red when it has a fault.

[0051] Specifically, when the indicating light 3201 has a fault, the controller 31 not only controls the warning light 34 to flash, but also sends a fault warning to the server 2, the server 2 forwards the fault warning to the MES system 5, and the MES system 5 prompts the maintenance personnel to perform maintenance.

[0052] Further, when the maintenance personnel is maintaining the indicating light 3201, the maintenance personnel can enter the maintenance mode by clicking a maintenance button on a terminal (such as a tablet) or pressing a maintenance physical button arranged on the shelf 30, and the shelf 30 where the indicating light 3201 having a fault is located displays all the indicating lights 3201 in the order of displaying a first color, switching to a second color, and switching to a third color, so as to facilitate the maintenance personnel to observe the fault point.

[0053] In another embodiment, the controller 31 is further configured to control the warning lights 34 corresponding to the shelves 30 storing the materials required by the same project to display the same color, and control the warning lights 34 corresponding to the shelves 30 storing the materials required by different projects to display different colors, after receiving the material requirements of multiple projects at the same time.

[0054] Among them, the warning lights 34 corresponding to the shelves 30 storing the materials required by different projects displaying different colors can be that one warning light 34 includes multiple lamp beads, each lamp bead displays a color independently, when one shelf 30 stores the materials required by both project A and project B, two lamp beads of the warning light 34 are lit and display different colors respectively; or by arranging multiple warning lights 34 on one shelf 30, when one shelf 30 stores the materials required by both project A and project B, two warning lights 34 are lit and display different colors respectively.

[0055] Specifically, the process of the electronic warehouse 1 placing materials is as follows:

[0056] First, the corresponding number of shelves 30 is configured in the electronic warehouse 1 as needed, the number of each shelf 30 and the number of each storage site 302 are written into the server 2 through software, and the written number information is uploaded to the MES system 5 and stored in the intelligent shelf 30; secondly, a terminal device is used to enter the MES system 5, click to place materials in the MES system 5, and scan the code on the material with the terminal device, the MES system 5 automatically allocates an empty storage site 302 to the material (the automatic allocation principle can be to allocate the same material in an area or randomly allocate, which is not limited here), then the warning light 34 on the shelf 30 corresponding to the empty storage site 302 lights up with the corresponding color, at the same time, the indicating light 3201 corresponding to the empty storage site 302 also lights up with the corresponding color (the color displayed by the indicating light 3201 can be the same as or different from the color displayed by the warning light 34, usually the same), the worker finds the empty storage site 302 according to the indication of the warning light 34 and the indicating light 3201, puts the material into the empty storage site 302, and clicks to confirm, then the MES system 5 stores the corresponding relationship between the material and the empty storage site 302.

[0057] Compared with the prior art, a two-dimensional code is pasted on each storage site, the worker scans the two-dimensional code of the storage site first, and then scans the material code to correspond and place the material, and some storage sites are small, so the distance between the pasted two-dimensional codes is small, therefore, the scanning gun is easy to scan the adjacent two-dimensional code, resulting in misplacement. In the embodiment, the storage site does not need to be pasted with a two-dimensional code, which reduces the workload, and when placing the material, only the material code needs to be scanned, and the two-dimensional code of the storage site does not need to be scanned, which reduces the probability of misplacement of the material.

[0058] The number of each shelf 30 and the number of each storage site 302 are written into the server 2 by software, and the addresses of each shelf 30 and each storage site 302 need to meet the requirement of uniqueness. In one embodiment, the number of each shelf 30 and the number of each storage site 302 on the shelf 30 are determined according to the number of shelves 30 and the number of storage sites 302 on each shelf 30. For example, when the number of shelves 30 is less than 1000, the number of shelves 30 can be completed by only three digits, for example, when the number of shelves 30 is 999, the number can start from 001 and be numbered to 999 in turn. Correspondingly, after determining the number of the shelf 30, the number of each storage site 302 is numbered according to the number of storage sites 302, for example: a shelf 30 has 1400 storage sites, the number of the shelf 30 is 001, and the number of the storage sites of the shelf 30 is 001XXXX, XXXX starts from 0001 to number the storage sites 302, and ends at 1400 (all numbers are for illustration only).

[0059] Specifically, the process of picking materials in the electronic warehouse 1 is as follows:

[0060] When there is a production demand, the staff issues a material demand work order through the MES system 5, the corresponding indicator light 3201 of the storage site 302 corresponding to the material on the work order and the warning light 34 on the shelf 30 where the material is located are lit in corresponding colors. The staff first finds the corresponding shelf 30 according to the guidance of the warning light 34, and then finds the corresponding storage site 302 according to the guidance of the indicator light 3201 to take out the material, and clicks to complete the delivery on the terminal. The corresponding indicator light 3201 is extinguished, and the storage site 302 is marked as an empty storage site 302 by the MES system 5.

[0061] The above is the implementation of the embodiments of the present application. It should be noted that for ordinary skilled persons in the technical field, without departing from the principles of the embodiments of the present application, a number of improvements and refinements can be made, which are also considered within the protection scope of the present application.
