A method for identification of inbound and outbound warehouses

Abstract

The present invention relates to the field of warehouse management, in particular to a method for identification of entering and leaving the warehouse. Specifically, two sensors are respectively arranged on the outer side of the warehouse door and the inner side of the door to replace the traditional one sensor. In addition, by timing, when one of the two sensors When the sensor first recognizes the sensing signal, timing starts; when another sensor recognizes the sensing signal, the first timing duration is obtained; if the first timing duration is less than the first preset time, and another sensor recognizes the sensing signal, Explain that the material moves from the sensing area of ​​one sensor to the sensing area of ​​another sensor. In order to eliminate the phenomenon of misreading, this step is added: restart the timing and judge that the sensor that first recognizes the sensing signal is within the second preset time range Whether the induction signal is recognized, if the induction signal is no longer recognized, it can be determined that the material is out of the warehouse or in the warehouse, if it is recognized, it is likely to be misread.

Description

technical field [0001] The invention relates to the field of warehouse management, in particular to a warehouse-in and out-recognition method. Background technique [0002] The traditional warehouse management system uses a sensor in the door area, which is associated with the system's counting system (such as a counter), and the electronic tag (the electronic tag is composed of a chip and an antenna, and each electronic tag has a unique ID number and user data) area) is set on the material, when the warehouse keeper picks up the material and enters the sensing area of ​​the sensor, the sensor recognizes the product information and other data sent by the electronic tag, triggers the counting system connected to it, and judges whether it is by the parity counted by the counting system Outbound or Inbound. [0003] However, there are misreading phenomena in this kind of warehouse management system, specifically: when the warehouse keeper picks up the materials and enters the ...

Problems solved by technology

[0003] However, there are misreading phenomena in this kind of warehouse management system, specifically: when the warehouse keeper picks up the materials and enters the sensing area of ​​the sensor, he finds that the materials have been picked up incorrectly and needs to return for replacement. At this time, because the warehouse keeper is in the sensing area, the counting system has already After the counting is completed, the warehouse keeper returns to the warehouse to replace the materials. If the judgment result of the counting system is that the warehouse keeper has picked up a certain material and left the warehouse, but in fact the warehouse keeper has not left the warehouse, resulting in misreading Happening

[0004] There is currently no solution to this misreading phenomenon
