The server 12 is configured to search preset notch information based on the cargo information acquired by the scanning device 11, obtain target unloading notch information corresponding to the cargo information, and send the target unloading notch information to the single chip microcomputer; the single chip microcomputer 14 controls the executing mechanism to automatically unload the goods to the target unloading stop based on the acquired target unloading stop information and the address information of the unloading stop. The single chip microcomputer 14 can be arranged at the end of the transportation unit, can also be arranged at the end of the goods unloading notch, and can also be respectively arranged at the end of the transportation unit and the end of the goods unloading notch. The wireless transceiver 13 is used for wireless communication between the single chip microcomputer and the server 12.
In this embodiment, the number of the scanning devices 11 is one, the server 12 is connected to the scanning devices 11 and the wireless transceiver 13 by wires, and the transportation unit and the unloading stop are respectively provided with a single chip microcomputer. The automated sorting system 10 is adapted to interact with the transport units and the discharge gates to automatically discharge the cargo on the transport units to the discharge gates for the cargo.
It should be noted that, the present embodiment is suitable for the transportation unit to move along the track to the vicinity of the wireless transceiver 13, and when the transportation unit detects that the inside of the transportation unit has the unloading information, the transportation unit does not receive the target unloading slot information sent by the server 12, and if the inside of the transportation unit does not have the unloading information, the transportation unit receives and analyzes the target unloading slot information.
The server 12 may be connected to the scanning device 11, the transport unit, and the one-chip microcomputer of the unloading bay through RS232 ports.
In this embodiment, only one server 12 is provided, and broadcasts all the corresponding transportation units to issue the target unloading slot information, but in a variation of this embodiment, there may be a plurality of servers 12 to adapt to a sorting usage scenario with a plurality of tracks and a plurality of transportation units.
The sorting system provided by the embodiment is suitable for controlling the transport unit and the unloading stop on the track so as to realize the automatic unloading of the goods on the transport unit to the unloading stop of the goods. Wherein the scanning device 11 has the function of identifying the goods on the transport unit. The goods can be preset with identification function such as bar code, two-dimensional code, etc., and the scanning device can be a bar code recognizer, a two-dimensional code recognizer, a camera, etc. corresponding to the goods identification, when the scanning device 11 can not detect the goods information, the goods information can also be identified through manual scanning. The cargo information may be directly transmitted from the scanning device 11 to the server 12. The server 12 may obtain the cargo information and its corresponding notch information (i.e., target unloading notch information).
The preset relationship between the goods information and the stop information can be preset or can be formed by real-time input for storage. When the preset information is set in advance, the server 12 inputs the cargo information and the preset notch information, and then, after the scanning device 11 detects the cargo information, the server 12 receives the cargo information and calls the preset notch information corresponding to the cargo information as the target unloading notch information. When the real-time input is formed by the storage, the server 12 generates the target unloading notch information randomly or according to a preset function (for example, sequentially according to the unloading notch codes) after receiving the cargo information detected by the scanning device 11, and stores the cargo information and the generated target unloading notch information.
Further, the single chip microcomputer 14 includes a reader/writer and a memory. The memory is suitable for storing the notch information of the unloading notch; the reader-writer is suitable for rewriting the notch information to the memory according to an external instruction, or inquiring and outputting the notch information stored in the memory.
After receiving the cargo information sent by the scanning device 11, the server 12 may also query the target unloading notch information from the preset information based on the cargo information, or generate the target unloading notch information in real time based on the cargo information. The notch information is generated based on the code of the discharge notch, i.e. representing the code of the discharge notch.
In this embodiment, the single chip microcomputer is further configured to control the unloading shelves to send address information of the unloading shelves in a wireless transmission manner, and the unloading shelves may also send the address information independently in a wireless transmission manner. The address information of the unloading port is the code information of the unloading port.
The transport unit runs along a predetermined track after receiving the target discharge slot information transmitted from the server 12. And receiving the address information of the unloading shelves in the operation process, and automatically unloading the cargos on the vehicle to the unloading shelves generating the corresponding address information of the unloading shelves under the condition that the single chip microcomputer at the transport unit end judges that the received target unloading shelves information is consistent with the address information of the unloading shelves.
In this embodiment, the judgment of whether the received target unloading notch information is consistent with the address information of the unloading notch may be performed in the single chip of the unloading notch end, and the single chip of the unloading notch end sends the unloading instruction to the transport unit according to the judgment result. The single chip microcomputer at the end of the transport unit can also independently receive the address information sent by the unloading shelves in the operation process, judge whether the received address information of the unloading shelves is consistent with the target unloading shelves, automatically unload the goods on the vehicle to the unloading shelves generating the address information if the received address information of the unloading shelves is consistent with the target unloading shelves, and finish the unloading action. The single chip microcomputer at the end of the transport unit can also send the information of the target unloading notch to the single chip microcomputer at the end of the unloading notch; and after receiving the target unloading stop information, the single chip microcomputer at the unloading stop end compares the received target unloading stop information with the address information of the single chip microcomputer, and controls the actuating mechanism to automatically unload the goods to the target unloading stop when the comparison result is completely consistent.
In addition, an optical sensor is arranged at the unloading notch and used for detecting whether goods fall in or not; if the cargo is detected to fall, the unloaded information is generated and sent to the server 12. Under the condition that a plurality of unloading shelves have the same address information, an optical sensor arranged on the unloading shelves detects whether the goods on the unloading shelves are full; and if the goods in the unloading shelves are full, the unloading shelves stop receiving the target unloading shelves information sent by the transport units.
Further, in the present embodiment, the short-range wireless communication is adopted between the transportation unit and the unloading gate to ensure the accuracy of the unloading position and the effectiveness of the wireless communication. Specifically, the method comprises the following steps:
the server 12 end is provided with a wireless transceiver 13, and the target unloading notch information is sent to the single chip microcomputer at the transportation unit end through the wireless transceiver 13. The transport unit end is also provided with a wireless transceiver 13 for receiving target discharge gate information.
It should be noted that the wireless transceiver 13 may be disposed in a plurality of ways around the track, so that the transportation unit can effectively obtain information. The radio 13 may be controlled using a PC serial line.
The discharge operation information generated in the one-chip microcomputer at the transport unit side may be generated based on two pieces of information, one of which is discharge information in the transport unit and the other of which is address information of a discharge slot in the transport unit in accordance with the target discharge slot information. Of course, in a specific embodiment, the detection processes of the two pieces of information may be various:
in a first variation, the single chip microcomputer at the end of the transport unit detects that the inside of the vehicle has unexecuted unloading information, and then receives the address information of the unloading notch wirelessly transmitted by the single chip microcomputer at the end of the unloading notch, and when the comparison target unloading notch information is consistent with the received address information of the unloading notch, the single chip microcomputer at the end of the transport unit generates the unloading operation information;

in a third variation, the single chip microcomputer at the end of the transport unit does not detect the existence of the unloading information again in the process of generating the unloading operation information, and when the comparison target unloading notch information is consistent with the received unloading notch information, the single chip microcomputer at the end of the transport unit directly generates the unloading operation information.
The transport unit in the above embodiments is a trolley, such as a transport vehicle, capable of independent operation and independent discharge.
The transportation unit of the invention independently receives the target unloading shelves information corresponding to the cargo information, and independently interacts the information with the current corresponding unloading shelves, and automatically unloads the cargo to the target unloading shelves under the condition that the obtained target unloading shelves information is consistent with the address information of the unloading shelves. The transport units and the unloading shelves in the technical scheme of the invention can independently carry out information interaction, carry out information transmission with the server, receive scheduling information and return instructions of the server, carry out operation and unloading according to the received information independently by each transport unit, feed back information, and greatly improve unloading efficiency and reduce system damage rate because the unloading instructions are independently generated and controlled.
