Embodiment 1

[0043] The connection structure of the logistics label is as follows figure 1 shown.

[0044] The controller is the master device, and the logistics tag is the slave device. The controller and the logistics tag use the Sub-1GHz wireless signal of the shared channel to communicate. The logistics label has the functions of wireless signal sending and receiving and monitoring.

[0045] This embodiment provides a method for reading batch logistics labels, including the following steps:

[0046] S1. The logistics label receives a read instruction sent by the controller, the read instruction includes a maximum value of a random number, and generates a random number not greater than the maximum value.

[0047] Specifically:

[0048] (1) All logistics tags enter the state of receiving instructions after startup.

[0049] (2) The controller initiates a read instruction, which includes a maximum value of a random number whose size is approximately equal to the number of logistics l...

Embodiment 2

[0075] The features of this embodiment that are the same as those of Embodiment 1 will not be described in detail. The features of this embodiment that are different from Embodiment 1 are:

[0076] The time to start monitoring is random number × unit time (for example, 1.5 milliseconds).

Abstract

The present invention relates to a reading method of batch logistics labels and a logistics label system. The method comprises the steps of: receiving a reading command sent by a controller, and generating a random number being not larger than an maximum value; performing wireless signal monitoring, finishing monitoring if there are logistics label signals, and sending response signals if valid wireless signals are not received; entering a state of receiving response confirmation if other logistics labels monitor the response signals; receiving the response confirmation signals by the logistics labels sending the response signals, and quitting a reading command process; and allowing the logistics labels without sending the response signals to repeatedly perform the steps until all the logistics labels send the response signals and receive the response confirmation signals sent by the controller. Through adoption of the wireless signal monitoring technology, the reading method of batchlogistics labels and the logistics label system monitor wireless signals around are valid or not, employ the random number to diverge the wireless signal monitoring duration to effectively control theprobability of conflict generation of the logistics electronic labels sending wireless signals, and employ the wireless signal response confirmation mechanism to effectively reduce the active numberof the logistics electronic labels.

Description

technical field [0001] The invention belongs to the field of logistics, and in particular relates to a method for reading batch logistics labels and a logistics label system. Background technique [0002] As e-commerce penetrates into people's daily life, more and more people purchase daily necessities through online shopping, and the use of logistics labels for logistics management is becoming more and more common. When multiple logistics tags communicate with the reader, the wireless signals interfere with each other and cause data collisions. How to quickly and effectively read the information in the batch logistics labels has become a difficult problem. Common methods include enumeration and signal anti-collision algorithms. The enumeration method is inefficient and requires a lengthy process when the tag ID number is long. The signal anti-collision algorithm is relatively complicated, and it is generally difficult to master, and when the number of logistics labels is...
