Description

Technical Field

[0001] The invention belongs to the field of logistics sorting, and in particular relates to a logistics sorting trolley structure and a numbering method thereof. Background Art

[0002] In the field of logistics sorting, logistics sorting equipment can generally be divided into linear narrow-belt sorting machines and circular cross-belt sorting machines. The cargo parcels need to be scanned by the package supply table and then transferred to the trolley via the conveyor belt. After the cargo parcels run to the designated grid on the sorting machine, the trolley moves to sort the cargo parcels.

[0003] For example, a package supply system and method disclosed in patent CN202410673646.X specifically introduces the working principle and method of a logistics sorting machine, wherein the import module, narrow-band sorting module, and main control module described in detail need to calculate the package supply and package drop paths through data algorithm analysis; For example, a cross-belt control method, system, computer equipment, and storage medium disclosed in patent CN113333298A introduces receiving barcode data sent by a scanning device when detecting that the motion parameters of a cross-belt trolley are consistent with preset parameters; determining the target cross-belt trolley number corresponding to the barcode data according to the cross-belt trolley data and the preset parameters; sorting and controlling the corresponding objects according to the barcode data and the target cross-belt trolley number, and when calculating the data, it is necessary to ensure that the trolley number is accurate;

[0004] According to the existing technology, the number of the trolley is set by the dial of the driver. When assembling and debugging the sorting machine, the dial setting is performed manually. Since the dial address is usually calculated in binary, the installation and debugging personnel need to be familiar with binary calculation, which affects the installation and debugging progress.

[0005] During the debugging process, due to the limited dial address, that is, the maximum address is 31, when the number of carts in the sorting machine is greater than 31, group control is required; if the lead car is to be changed, all the cart dials need to be manually reset according to the existing technology, which seriously reduces the debugging and maintenance efficiency. Therefore, a solution is needed to solve the above problems.

[0006] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0007] In order to solve the above problems, the purpose of the present invention is to provide a logistics sorting trolley structure and its numbering method, which sets the software address number of the infrared photoelectric driver address through an external photoelectric emission module and judges the status of the sorting trolley through the return code.

[0008] To achieve the above-mentioned purpose, the present invention proposes a logistics sorting cart structure, including a sorting cart, a communication transmitting unit and a driving unit, the driving unit is provided with a receiving module, the communication transmitting unit is provided with a transmitting module, the sorting cart is installed on a logistics line, and the driving unit is installed on the sorting cart, the communication transmitting unit is fixedly installed in the logistics line, when the sorting cart passes through the communication transmitting unit during the movement of the logistics line, the transmitting module and the receiving module are emitted from each other and information is exchanged.

[0009] In one example, the communication transmitting unit is an infrared photoelectric transmitter.

[0010] In one example, the driving unit is an infrared photoelectric driver.

[0011] In one example, the receiving module is a photoelectric receiver.

[0012] In one example, the transmitting module is a photoelectric transmitter.

[0013] A method for numbering a logistics sorting trolley structure, the method comprising the following steps:

[0014] S1: Set the dial address of the driving unit of the expected number one sorting cart to 1, start the logistics line, make the sorting cart follow the logistics line, and make the driving unit of each sorting cart pass through the communication transmitting unit in turn;

[0015] S2: When the running speed of the sorting trolley is stable, the dial addresses of all the driving units are set to 0, and the write address instruction is sent to number each of the sorting trolleys in sequence;

[0016] S3: Since the dial code of the first sorting trolley is set to 1 first, the communication transmitting unit will automatically identify the driving unit carried by the first sorting trolley, and write its vehicle software address as 1, and then set the software addresses of the subsequent driving units in turn in order, so as to realize the automatic numbering of the sorting trolleys;

[0017] S4: After the communication transmitting unit sends the write address instruction, the driving unit will return a code to the communication transmitting unit, which is transmitted to the host computer via the bus. The count value is verified by the return code, and the number of the sorting carts actually assembled in the logistics line is combined to determine whether the automatic encoding is set successfully.

[0018] S5: If the return code check count value does not match the actual number of the sorting carts, it is determined that there is an omission. Based on the uniform operation speed of the equipment when setting the address, the pitch of the adjacent sorting carts is consistent, so that the return code time interval of each driving unit to the communication transmitting unit is also consistent. Based on this feature, if the time interval between two adjacent return codes exceeds the range, the sorting cart with the problem can be quickly located according to the corresponding address in the return code;

[0019] S6: The driving unit returns a code to the communication transmitting unit, and the count value is compared with the input value. If there is an abnormal return code and the number of cyclic writing is less than 2, the number is rewritten starting from the time when the first sorting trolley passes by, and the newly written number will overwrite the original number;

[0020] S7: After the second number is written, if the return code is still abnormal and the number of cyclic writes is greater than 2, it is determined that the sorting trolley hardware fails. The return code time interval is calculated by the running speed and the trolley pitch, thereby determining the position of the faulty sorting trolley and stopping the machine for manual troubleshooting.

[0021] The logistics sorting trolley structure and numbering method thereof proposed by the present invention can bring the following beneficial effects:

[0022] 1. Using infrared photoelectric device communication transmission to replace the traditional manual dialing steps can greatly save numbering time and improve the numbering efficiency of sorting carts when facing a large number of sorting carts. The numbering error rate can be reduced by setting the return code, which can improve the installation and debugging progress;

[0023] 2. In the case of hardware damage to the sorting cart, the problem sorting cart can be quickly located through the return code, which greatly shortens the troubleshooting time and improves the efficiency of debugging and maintenance;

[0024] 3. The software address is used for numbering, which breaks through the address quantity limitation of traditional mechanical dialing. There is no need to set groups during debugging, and the sorting trolley address corresponding to the number is unique. When there is a problem with the sorting trolley, accurate and rapid positioning can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1 to Figure 6 As shown, an embodiment of the present invention proposes a logistics sorting cart structure, including a sorting cart 1, a communication transmitting unit 2 and a driving unit 3, a receiving module 5 is installed in the driving unit 3, a transmitting module 4 is installed in the communication transmitting unit 2, the sorting cart 1 is installed on the logistics line 6, and the driving unit 3 is installed on the sorting cart 1, and the communication transmitting unit 2 is fixedly installed in the logistics line 6. When the sorting cart 1 passes the communication transmitting unit 2 during the movement of the logistics line 6, the transmitting module 4 shoots at the receiving module 5 and exchanges information.

[0038] Specifically, the communication transmitting unit 2 may be an infrared photoelectric transmitter.

[0039] Specifically, the driving unit 3 may be an infrared photoelectric driver.

[0040] Specifically, the receiving module 5 may be a photoelectric receiver.

[0041] Specifically, the transmitting module 4 can be a photoelectric transmitter. A method for numbering a logistics sorting trolley structure comprises the following steps:

[0042] S1: Set the dial address of the infrared photoelectric receiver of the expected number one sorting trolley 1 to 1, start the logistics line 6, make the sorting trolley 1 move along the logistics line 6, and make the infrared photoelectric driver of each sorting trolley 1 pass the infrared photoelectric transmitter in turn;

[0043] S2: When the running speed of the sorting trolley 1 is stable, set the software addresses of all infrared photoelectric drivers to 0, and start sending write address instructions to number each sorting trolley 1 in sequence:

[0044] As shown in Table 1 and Table 2,

[0045]

[0046] Table 1 Transmitter module address modification instructions

[0047]

[0048] Table 2 Receive module return code

[0049] The address of the transmitting module is 1 (set by the transmitting module dial), and the address of the infrared photoelectric driver is written as 1;

[0050] Send command: 83 01 01 00 00 00 00 00

[0051] Receive return code: 99 01 00 00 01 01 01 00

[0052] The address of the infrared transmitter module is 1 (set by the transmitter module dial), and the address of the infrared photoelectric driver is written as 2;

[0053] Send command: 83 01 02 00 00 00 00 03

[0054] Receive return code: 99 02 00 00 01 02 01 00

[0055] And so on, until the required number is written;

[0056] The above can be used to determine whether the current sorting cart address is correct and whether the writing is successful through the Byte2 address;

[0057] The above can be judged by Byte5 counting whether the sorting vehicle has received the instruction;

[0058] The above can be counted by Byte6 to know the number of sorting carts that have been written successfully, and combined with the actual number of sorting carts to determine whether there are any omissions;

[0059] The above can be used to determine whether the sorting trolley has a fault through the content of Byte4, and B7-B0 can correspond to a fault information respectively;

[0060] The host computer will display the sent command and the received return code, and add a timestamp before the command, thereby calculating the time interval between two adjacent commands and determining the missing position;

[0061] Due to the free protocol and the reserved bits in the message, the address can be expanded infinitely in theory, and other status displays or functions can be added according to needs;

[0062] The number one sorting vehicle will be identified in the above writing process, and the number writing will start when it communicates with the transmitting module;

[0063] or

[0064] The address of the transmitter module is 1 (set by the transmitter module dial), and the address of the infrared photoelectric driver is written as 0;

[0065] Send command: 83 01 00 00 00 00 00 01

[0066] Receive return code: 99 01 00 00 01 01 01 00

[0067] When the address is set to 0, the host computer determines the time T0 required for all sorting carts to be set to 0 by combining the number of sorting carts input and the equipment running speed. When the actual time T1>T0 (ensuring that all sorting carts are set to 0), the host computer prompts that the setting to 0 is completed and starts the next step of writing the address;

[0068] In the above writing method, the first sorting cart that receives the instruction sent by the host computer is set as number 1;

[0069] S3: Since the dial of the number one sorting trolley 1 is set to 1 first, the infrared photoelectric transmitter will automatically identify the infrared photoelectric driver carried by the number one sorting trolley 1, and write its car software address to 1, and then set the subsequent infrared photoelectric driver software addresses in order, so as to realize the automatic numbering of the sorting trolley 1;

[0070] S4: After the infrared photoelectric transmitter sends the write address instruction, the infrared photoelectric driver will return the code to the infrared photoelectric transmitter, which is transmitted to the host computer via the bus. The count value is verified by the return code, and the number of sorting carts 1 actually assembled in the logistics line is combined to determine whether the automatic encoding is set successfully.

[0071] S5: If the return code check count value does not match the actual number of sorting carts 1, it is judged that there is an omission. Based on the uniform operation speed of the equipment when setting the address, the pitch of adjacent sorting carts 1 is consistent, so the return code time interval of each infrared photoelectric driver to the infrared photoelectric transmitter is also consistent. Based on this feature, if the time interval between two adjacent return codes exceeds the range, the problem sorting cart 1 can be quickly located according to the corresponding address in the return code;

[0072] S6: The infrared photoelectric driver returns a code to the infrared photoelectric transmitter, and the count value is compared with the input value. If there is an abnormal return code and the number of cycle writes is less than 2, the number will be rewritten starting from when the first sorting cart 1 passes by, and the newly written number will overwrite the original number;

[0073] S7: After the second number is written, if the return code is still abnormal and the number of cyclic writes is greater than 2, it is determined that the hardware of sorting trolley 1 is faulty. The return code time interval is calculated by the running speed and trolley pitch, thereby determining the position of the faulty sorting trolley 1 and stopping the machine for manual troubleshooting.

[0074] Working principle: An infrared photoelectric driver is installed on each sorting trolley, and an infrared photoelectric transmitter is fixedly installed in the logistics line. When the sorting trolley runs in the logistics line, it will pass by the infrared photoelectric transmitter. At this time, the photoelectric transmitter and the photoelectric receiver will shoot at each other and exchange information.

[0075] Any sorting trolley is selected as the number one sorting trolley, and its infrared photoelectric driver dial code is set to 1. The command is sent through the host computer. The infrared photoelectric transmitter will first set the software address of the infrared photoelectric driver on all sorting trolleys to 0, and then the host computer sends a command again to set the software address of the sorting trolley. After the infrared photoelectric transmitter recognizes the number one sorting trolley, it writes the software address to the infrared photoelectric driver in sequence from 1. After the double software address is written, the host computer will use the infrared photoelectric driver to judge the number of return codes of the infrared photoelectric transmitter, and locate the position of the problem trolley in combination with the time interval of the return code. After confirmation, the numbering of the logistics sorting trolley is completed. If there is an abnormal return code, it is judged as omission, and the numbering cycle is repeated again. If there is no abnormality after the cycle, it is judged to be numbering. If there is still an abnormal return code, the return code time interval is calculated by the running speed and the trolley pitch, the position of the faulty sorting trolley is determined, and the machine is stopped to troubleshoot.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
