[0044] like Figure 1 As shown, Figure 1 This is a flow chart of a method for detecting inverted goods based on RFID technology according to an embodiment of the present invention;

[0045] Reference Figure 1 The embodiment of the present invention provides a method for detecting cargo inversion based on RFID technology, comprising:

[0046] like Figure 2 As shown, an electronic tag 1 is provided on the outer side of the target cargo package, the electronic tag 1 is provided with a first electrode contact 2 and a second electrode contact 3, the first electrode contact 2 is connected with a conductive chain 4, the electronic tag 1 has a circuit-on state in which the conductive chain 4 is spread out in the direction of gravity and is in contact with the second electrode contact 3, and a circuit-off state in which the conductive chain 4 is gathered away from the direction of gravity and is separated from the second electrode contact 3;

[0047] In some embodiments, the conductive chain 4 is provided with a plurality of conductive balls 5 , which are connected in sequence, and the second electrode contact 3 is provided with an arc-shaped recess 6 , the curvature of which matches that of the conductive ball 5 .

[0048] S10: In response to the cargo inversion detection signal, control the RFID reader to start reading the electronic tag 1;

[0049] When the conductive chain 4 is unfolded in the direction of gravity and is in contact with the second electrode contact 3, the electronic tag 1 is in a circuit-on state, the target goods are placed upright, and the RFID reader can read the electronic tag 1. When the conductive chain 4 is gathered away from the direction of gravity and separated from the second electrode contact 3, the electronic tag 1 is in a circuit-off state, the target is inverted, and the RFID reader cannot read the electronic tag 1. In this way, according to the on-off of the internal circuit of the electronic tag 1 and the status of the electronic tag 1 identified by the RFID reader, it is detected whether the target goods are inverted.

[0050] S20: Acquire the current number of electronic tags 1 recognized by the RFID reader in real time;

[0051] Every time the RFID reader reads and identifies an electronic tag 1, the current number of electronic tags 1 increases by one. If the RFID reader does not read the electronic tag 1, the current number of electronic tags 1 does not increase or is not updated.

[0052] S30: Determine whether the current number of electronic tags 1 meets a preset condition;

[0053] S41: If the current number of electronic tags 1 meets the preset conditions, the goods are placed correctly information is sent;

[0054] S42: If the current number of electronic tags 1 does not meet the preset conditions, a goods inversion alarm message is sent.

[0055] In some embodiments, it further comprises:

[0056] Detecting that the target cargo is in a loading state, and in response to a cargo inversion detection signal, obtaining single loading and unloading data of the target cargo;

[0057] According to the single loading and unloading data, the preset condition is determined to be the number of preset electronic tags 1 recognized by the RFID reader within a set period;

[0058] If the increment of the current number of electronic tags 1 in the interval setting period meets the preset number of electronic tags 1, the goods are placed correctly information is sent;

[0059] If the increment of the current number of electronic tags 1 in the interval setting period does not meet the preset number of electronic tags 1, a goods inversion alarm message is sent.

[0060] During the loading stage before the target goods are transported, the electronic tag 1 structure and detection method designed above are used to determine whether the target goods are inverted during loading into the carriage, and timely detection and discovery are made, and an inversion alarm message is sent in time to remind the staff.

[0061] Usually, different target goods have different loading times. For this, the preset number of electronic tags 1 that the RFID reader recognizes within a set period is designed as needed. For example, if the number of target goods loaded within a set period is m, the corresponding number of electronic tags 1 is also m. If all goods are placed upright, the preset number of electronic tags 1 recognized by the RFID reader within the set period is m. In this way, the inverted goods situation is determined based on whether the current number of electronic tags 1 recognized by the RFID reader within the set period meets the preset number of electronic tags 1, and the inverted goods information is sent in a timely manner.

[0062] In some embodiments, detecting that the target cargo is in a loading state further includes:

[0063] Get the total increment of the current number of electronic tags 1 within N set periods;

[0064] Determine the total number of preset electronic tags 1 corresponding to N set periods;

[0065] If the total increment of the current number of electronic tags 1 meets the preset total number of electronic tags 1, the goods are placed correctly information is sent;

[0066] If the total increment of the current number of electronic tags 1 does not meet the preset total number of electronic tags 1, a goods inversion alarm message is sent.

[0067] Obtain the total increment of the current number of electronic tags 1 within multiple set periods, and determine the total number of preset electronic tags 1 corresponding to multiple set periods. Compare the two to determine whether the target goods loaded on the vehicle are inverted within multiple set periods, so as to further improve the detection accuracy of inverted goods.

[0068] In some embodiments, it further comprises:

[0069] Detecting that the target goods are in a warehousing state, and in response to a goods inversion detection signal, obtaining single-time shelf-loading data of the target goods;

[0070] According to the single-time shelf-loading data, determining that the preset condition is the number of single-time electronic tags 1 recognized by the RFID reader;

[0071] If the current number of electronic tags 1 matches the number of single electronic tags 1, the goods are placed correctly information is sent;

[0072] If the current number of electronic tags 1 does not meet the preset number of electronic tags 1 per time, a goods inversion alarm message is sent.

[0073] In some implementations, detecting that the target goods are in a warehousing state further includes:

[0074] Determine the target shelf based on the target goods information, and monitor the pressure sensor information on the target shelf in real time;

[0075] When the pressure value detected by the pressure sensor increases, a cargo inversion detection signal is generated.

The electronic tag 1 has a circuit-on state in which the conductive chain 4 is unfolded toward the direction of gravity and is in contact with the second electrode contact 3, and a circuit-off state in which the conductive chain 4 is gathered away from the direction of gravity and is separated from the second electrode contact 3.

[0082] In some embodiments, the determination module is further configured to:

[0083] If the increment of the current number of electronic tags 1 in the interval setting period meets the preset number of electronic tags 1, the goods are placed correctly information is sent;

[0084] If the increment of the current number of electronic tags 1 in the interval setting period does not meet the preset number of electronic tags 1, a cargo inversion alarm message is sent; wherein, when the target cargo is detected to be in a loading state, a single loading and unloading data of the target cargo is obtained in response to the cargo inversion detection signal;

[0085] According to the single loading and unloading data, the preset condition is determined to be the number of preset electronic tags 1 recognized by the RFID reader within a set period.
