when a goods transportation terminal continuously receives a first number of inquiry signals, the goods transportation terminal determines that the goods transportation terminal is stably communicated with the goods processing terminal;

and the goods transportation terminal receives the identification information sent by the goods processing terminal and compares the identification information with the package information.

The judgment of whether stable communication is established or not and the comparison between the identification information and the package information are given to the freight terminal for doing so, so that the real-time communication between the freight terminal and the server can be omitted, the electromagnetic interference in space is further reduced, and meanwhile, the cost is greatly saved. Furthermore, the receipt information is also sent to the goods processing terminal by the goods transportation terminal, and then sent to the server by the goods processing terminal, because the goods processing terminal is usually fixedly arranged, and has the advantages of convenience in erection and low cost no matter wired communication or wireless communication is carried out with the server.

The first number ranges from 10 to 20, inclusive, such as any of 10.0, 12.0, or 20.0; the transmission interval of adjacent interrogation signals ranges from 10 microseconds to 100 microseconds, such as any one of 10.0 microseconds, 56.2 microseconds, or 100.0 microseconds. Reducing the sending interval of the inquiry signal as much as possible is beneficial to quickly establishing stable communication connection between the cargo processing terminal and the cargo transportation terminal, and the parameter range is an optimal range value after theoretical calculation and actual inspection, and can be adjusted correspondingly according to actual needs, which is not described herein again.

Furthermore, the inquiry signal comprises the identification information, so that the cargo transportation terminal can directly read the identification information in the inquiry information after continuously receiving the first amount of inquiry information and compare the identification information with the package information, the process is further simplified, and the working efficiency of the program is improved.

The logistics sorting method provided by the invention receives the package information; when a cargo transportation terminal continuously receives a first number of inquiry signals, determining that the cargo transportation terminal is stably communicated with the cargo processing terminal, wherein the cargo transportation terminal sequentially passes through a plurality of cargo processing terminals along a preset line, the cargo processing terminals circularly send the inquiry signals, and the radiation ranges of the inquiry signals of different cargo processing terminals are not overlapped; receiving identification information sent by the cargo processing terminal, and comparing the identification information with the package information; and when the identification information accords with the package information, starting an action unit of the cargo transportation terminal to finish a preset action. According to the goods processing terminal, the inquiry signals are sent ceaselessly according to the preset interval, and the goods conveying terminal determines to establish stable communication connection after receiving a certain number of inquiry signals, so that the goods conveying terminal is ensured to be in a stable communication range, and the possibility of program errors caused by unsmooth communication is reduced; in addition, a plurality of goods processing terminals with non-overlapping inquiry signal ranges are arranged, so that program error report caused by mutual interference of signals from different goods processing terminals is avoided, the stability of program operation is improved, the problem of anti-interference communication is solved, and the use cost is reduced.

On the basis of the first specific implementation manner, the step after the preset action is completed is further processed, and the step includes:

step S201: package information is received.

Step S202: when a goods transportation terminal continuously receives a first number of inquiry signals, it is determined that the goods transportation terminal is in stable communication with the goods processing terminal, wherein the goods transportation terminal sequentially passes through a plurality of goods processing terminals along a preset line, the goods processing terminals circularly send the inquiry signals, and the radiation ranges of the inquiry signals of different goods processing terminals are not overlapped.

Step S203: and receiving the identification information sent by the cargo processing terminal, and comparing the identification information with the package information.

Step S204: and when the identification information accords with the package information, starting an action unit of the cargo transportation terminal to finish a preset action.

Step S205: and after the preset action is completed, receiving receipt information sent by the cargo transportation terminal.

The difference between this embodiment and the above embodiment is that, in this embodiment, after the preset action is completed, the cargo transportation terminal sends the confirmation information again, and the remaining steps are the same as those in the above embodiment, and are not described herein again.

In this embodiment, after the preset action is completed, the goods transportation terminal sends the receipt information, which is equivalent to recording the processing result of the goods on a case, and once the goods are sorted in error, backtracking can be performed according to the receipt information to find problems.

Further, the response piece information is received when the identification information does not correspond to the package information. Since the cargo transportation terminal passes through the cargo processing terminals in sequence, even if the cargo transportation terminal does not interact with the cargo processing terminal (i.e. the action unit is not started), the receipt information passing through each cargo processing terminal can be recorded as data at each time point, so as to achieve the effect of monitoring the cargo, for example, the cargo transportation terminal should pass through the cargo processing terminals No. 1, No. 2, and No. 3 in sequence, and process the cargo at the cargo processing terminal No. 5, but the final cargo is not sent to the cargo processing terminal No. 5, but the receipt information sent by the cargo transportation terminal at the cargo processing terminals No. 1 and No. 2 is left in the system, but there is no subsequent receipt information, so that the cargo processing terminal is likely to fail between the cargo processing terminal No. 2 and the cargo processing terminal No. 3, so that the goods are not delivered to the No. 3 goods processing terminal. Furthermore, the receipt information comprises time information, and more bases for handling the freight transportation terminal are provided for workers.

According to the goods processing terminal, the inquiry signals are sent ceaselessly according to the preset interval, and the goods conveying terminal determines to establish stable communication connection after receiving a certain number of inquiry signals, so that the goods conveying terminal is ensured to be in a stable communication range, and the possibility of program errors caused by unsmooth communication is reduced; in addition, a plurality of goods processing terminals with non-overlapping inquiry signal ranges are arranged, so that program error report caused by mutual interference of signals from different goods processing terminals is avoided, the stability of program operation is improved, the problem of anti-interference communication is solved, and the use cost is reduced.

The following provides a complete flow of practical application of a specific embodiment, and a schematic structural diagram of a corresponding logistics sorting device is shown in fig. 4, wherein the cargo transportation terminal and the cargo processing terminal communicate with each other by using infrared rays, a circuit block diagram of the infrared communication device is shown in fig. 5, a logistics trolley 1 (i.e., the cargo transportation terminal described above, corresponding to a mobile-end infrared communication device) transports logistics packages to move on a guide rail, when the logistics packages pass through aphotoelectric switch 4, ablocking piece 3 triggers thephotoelectric switch 4 to generate a trigger pulse, and a packagebarcode scanning device 2 photographs and identifies barcodes of the logistics packages, and sends a trigger signal and a barcode identification result to ahost server 6 to process the triggering signal and the barcode identification result. Thehost server 6 processes the bar code identification result information to generate command information, converts the command information into a TCP packet, and sends the TCP packet to the off-board communication board 8 through an internet port TCP/IP protocol.

The off-board communication board 8 mainly comprises an FPGA and a network port protocol chip W5300, wherein the FPGA controls the chip W5300 to perform network communication with thehost server 6, and the network port information sent by thehost server 6 is converted into an RS422 serial port by using a TCP/IP protocol and sent to the fixed-endinfrared communication device 9 at the position of the cargo outlet node 5 (i.e., the cargo processing terminal described above, corresponding to the fixed-end infrared communication device). Firstly, the fixed endinfrared communication device 9 stores the received command information in a cache, then circularly transmits an inquiry signal, wherein the inquiry signal can be a fixed code pattern, when the logistics trolley 1 does not move to the position above the goods exit node 5, the mobile endinfrared communication device 10 does not receive the inquiry signal, and once the logistics trolley 1 enters the area of the goods exit node 5 in the moving process, the mobile endinfrared communication device 10 starts to receive the inquiry signal. In order to ensure that the mobile-sideinfrared communication device 10 enters a stable communication area, the reception signal of the mobile-sideinfrared communication device 10 is determined here, and it is considered that it enters a stable communication area when it continuously receives N (10 here) inquiry signals. At this time, the mobile-sideinfrared communication device 10 transmits a response signal of one byte downward. When the fixed endinfrared communication device 9 receives the response signal, the command information in the cache is sent out, after the mobile endinfrared communication device 10 receives all the command information, the command information is transmitted to the execution mechanism of the trolley, and after the execution mechanism of the trolley executes the command, a piece of return information is returned to the mobile endinfrared communication device 10. At this time, the mobile terminalinfrared communication device 10 sends the return information downward to the fixed terminalinfrared communication device 9, and the fixed terminalinfrared communication device 9 returns the received return information to thehost server 6 through the off-board communication board 8, thereby completing a communication closed loop.
