Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings, which are illustrated in the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 18.

As shown in fig. 1, the intelligent warehousing method according to an embodiment of the present invention includes:

step 100: acquiring a wake-up signal sent by a transmitting device;

the wake-up signal can be transmitted in a one-to-one manner or in a one-to-many manner, so that the wake-up signal transmitted by the transmitting device is acquired, and compared with a scanning or reader reading manner, the number of the wakened objects can be one or more, that is, the wakened objects can be wakened at the same time, and the working efficiency is greatly improved.

It can be understood that the transmitting device is arranged at the warehouse door or the position near the warehouse door, or the position where the object must pass through for entering and exiting the warehouse, so that the electronic tag 10 on the object can acquire the wake-up signal, the transmitting distance can be shortened, and the wake-up sensitivity can be improved.

Optionally, the wake-up signal is transmitted at a fixed interval, and the interval is in a range of 10ms to 500ms, preferably 200 ms.

Step 102: awakening the electronic tag 10 arranged on the object to be put in or taken out of the warehouse according to the awakening signal;

through set up the electronic tags 10 that can acquire the wake-up signal on waiting to go into and go out the object in storehouse, be convenient for when the object passes through emitter, electronic tags 10 on the object can acquire the wake-up signal and awaken up, be convenient for carry out the discernment work of its position through electronic tags 10 on every object initiative like this, rather than reading or scanning electronic tags 10 on each object through reading the ware or scanning, when making a plurality of objects pass through emitter position department simultaneously, electronic tags 10 on every object can both be awaken up and independently work separately, avoid the condition of misidentification or omission, the batch object goes out the warehouse entry efficiency and the rate of accuracy of discernment by a wide margin, and reduce the omission rate of discernment.

Step 104: determining the awakening time and the position of the object when the electronic tag 10 is awakened;

by determining the awakening time and the position of the object when the electronic tag 10 is awakened, basic data can be provided for determining the direction of the object entering and exiting the warehouse conveniently; in addition, the mode of waking up the electronic tag 10 by transmitting the wake-up signal is also beneficial to quickly searching the warehousing objects.

Step 106: the electronic tag 10 sequentially receives the wake-up signals transmitted by the plurality of transmitting devices;

step 108: determining each position of the object at each awakening moment according to each awakening signal;

step 110: determining the sequence of the object passing through a plurality of positions according to the sequence of the plurality of awakening moments;

step 112: determining the direction of the object entering or exiting the warehouse according to the sequence of the object passing through a plurality of positions

By arranging the plurality of transmitting devices at different positions on the line where the object is required to pass in and out of the warehouse, when the object passes through the different positions, the electronic tag 10 arranged on the object can be awakened for many times, the position of the object is determined at each awakening moment, and then the object can be judged to be in or out of the warehouse according to the sequence of passing through the different positions.

The electronic tags 10 are awakened, the positions of the objects are determined, and the in-out direction is judged according to different sequences of the positions where the objects pass after being awakened for multiple times, because the positions and the sequences of the positions where the objects pass are independently determined by the electronic tags 10 on each object, namely the in-out direction of each object is independently judged by the electronic tags 10, but the electronic tags 10 are not scanned one by a reader or scanning equipment, when the objects are simultaneously put in and taken out of a warehouse, the work originally completed by the reader or scanning equipment is respectively borne by the electronic tags 10 on each object, so that the accuracy of object identification and the accuracy of judgment of the in-out and warehousing directions of the objects are improved, omission is avoided, and the working efficiency is greatly improved.

It should be pointed out that even if two batches of objects are simultaneously delivered from the warehouse and the other batch of objects are delivered into the warehouse in the same warehouse entry channel or the same warehouse door, the technical scheme of waking up the electronic tag 10 in the application can accurately identify and judge the warehouse entry and exit directions of the two batches of objects in a very short time, and the warehouse entry and exit working efficiency and the operation convenience are greatly improved. In the prior art, due to the technical scheme that the objects are scanned one by adopting the reader or the scanning equipment to read the information of the electronic tags 10 on each object, the efficiency is low, and the electronic tags are easily interfered by other nearby electronic tags 10 to cause error reading.

As shown in fig. 2, the intelligent warehouse entry management method according to an embodiment of the present invention includes:

step 200: acquiring a first wake-up signal sent by a first transmitting device;

the first emitting device is arranged at a first position, the first position is arranged at a warehouse door, when an object passes through the warehouse door, the electronic tag 10 on the object can acquire the first wake-up signal sent by the first emitting device 20, and if the object is a plurality of objects, the plurality of objects can acquire the first wake-up signal at the same time.

Preferably, the signal transmitted by the first transmitting device is a low-frequency signal, or the first transmitting device is a low-frequency transmitting device.

Step 202: awakening the electronic tag 10 arranged on the object to be put in or taken out of the warehouse according to the first awakening signal;

step 204: determining a first awakening moment when the electronic tag 10 is awakened and the position number of the object;

the position of each transmitting device is numbered, and the wake-up signal transmitted by each transmitting device comprises the position number, so that when an object passes through the transmitting device, the electronic tag 10 on the object is awakened, and meanwhile the number of the position, namely the position number of the position where the object is located, can be received, and the position where the object is located can be determined;

in the present application, the first position is numbered odd 1;

the first awakening signal comprises a position number, so that the position of the object is expressed in a numbered mode, computer programs are simplified, the operation speed is improved, and the structure and the configuration of the first single chip microcomputer 104 are simplified, so that the cost can be reduced, the size of the first single chip microcomputer 104 is reduced, and the space is saved on the premise of ensuring the operation efficiency.

Step 206: determining the position of the object at the first awakening moment according to the parity of the position number;

judging the parity of a number, without pre-storing a database in the first single chip 104, the judgment logic is simpler, therefore, the position of the object at the first awakening moment is determined according to the parity judgment of the position number, the judgment logic is simple, and no complex operation is needed, so that the structure of the first single chip 104 on each electronic tag 10 can be simplified, the cost of the first single chip 104 is reduced, and the occupied space of the first single chip 104 is reduced.

Specifically, at the first wake-up time, the position number in the acquired first wake-up signal is 1, which is an odd number, so that it can be determined that the object is at the first position, i.e., at the door of the warehouse.

Step 208: acquiring a second wake-up signal emitted by the second emitting device 22;

the second emitter 22 is located at a second location, which is located outside the warehouse door, 5 meters from the first location.

Preferably, the signal transmitted by the second transmitting means is a low frequency signal, or alternatively, the second transmitting means is a low frequency transmitting means.

Step 210: awakening the electronic tag 10 arranged on the object to be put in or taken out of the warehouse according to the second awakening signal;

step 212: determining a second awakening moment when the electronic tag 10 is awakened and the position number of the object;

the second position is numbered 2.

Step 214: determining the position of the object at the second awakening moment according to the parity of the position number;

the position number 2 in the second wake-up signal acquired by the electronic tag 10 is an even number, and thus it is determined that the object is located at the second position, i.e. outside the warehouse door.

Step 216: determining the direction of the object entering and exiting the warehouse according to the sequence of the object passing through the two positions;

the object passes through a first position at the warehouse door and then passes through a second position outside the warehouse door, and therefore the object is determined to be delivered from the warehouse.

It can be understood that if at the first wake-up time, the position number in the first wake-up signal acquired by the electronic tag 10 is 2, and at the second wake-up time, the position number in the second wake-up signal acquired is 1, the position thereof at the first wake-up time is the second position; the position at the second awakening moment is the first position, namely the object firstly passes through the second position outside the warehouse door and then passes through the first position at the warehouse door, and the direction of the object entering and exiting the warehouse is the warehouse entry.

Further, if a plurality of objects are delivered from different directions, for example, two batches of objects, one batch of objects is delivered from the warehouse, and the other batch of objects is delivered from the warehouse, the low frequency transmitting device is adopted to transmit the wake-up signal, so that the electronic tags 10 on the objects respectively identify the positions of the objects, and therefore the two batches of objects do not need to stay for waiting for scanning or being read when passing through the position of the warehouse door, but are delivered into or withdrawn from the warehouse door according to the whole vehicle transportation mode, the efficiency of delivering the objects into or withdrawn from the warehouse is greatly improved, the identification accuracy is improved, and the leakage rate is reduced.

Furthermore, if the warehouse is provided with a plurality of doors, the position numbers of the doors where the transmitting devices are located are odd numbers, the positions where the transmitting devices outside the doors are located are even numbers, and whether the numerical values of the position numbers are the same or not, the entering and exiting directions of the objects can be rapidly judged through the parity and the sequence of the position numbers, so that the position information corresponding to each position number does not need to be prestored, and the logic of judging the positions of the objects is simplified.

It can be understood that when the warehouse has a plurality of gates, numbering is performed according to the above manner, and meanwhile, numbering of different values is performed on each position, and a position database corresponding to the position number is established, so that when the direction of the object entering and exiting the warehouse is judged, a specific entering and exiting route of each object can be determined through the position database corresponding to the position number, so as to facilitate retrospective management afterwards.

Specifically, for example, the warehouse has 2 gates, the number of the position of the No. 1 gate is 11, and the number of the position outside the No. 1 gate is 12; the number of the No. 2 door position is 21, and the number of the No. 2 door position is 22; the object A enters the warehouse from the door 1, the warehousing route can be embodied by the number 1211, the ex-warehouse can be embodied by the number 2122, the ex-warehouse route can be embodied by the number 2, so that the in-warehouse and out-warehouse route of the object A can be rapidly determined when tracing management is needed, meanwhile, in the judgment of the in-warehouse and out-warehouse direction of the object A, the warehousing direction is determined only by judging the parity and the sequence of the position numbers or directly judging the parity of the number at the position passed last, and the judgment logic is greatly simplified.

Step 218: storing the information of the direction of the object to enter or exit the warehouse;

the information of the warehouse-in and warehouse-out directions of the objects is stored in the electronic tag 10, so that the logistics path of the objects can be inquired and traced through the electronic tag 10 on the objects at any time, and the convenience of warehouse management is improved.

Step 220: the information of the direction of the object to enter or exit the warehouse is transmitted to the cloud platform 30.

Through the warehouse entry and exit direction information who sends the object to cloud platform 30, send the warehouse entry and exit information of a plurality of objects for cloud platform 30 to guarantee the timeliness and the accuracy of inventory information, still be favorable to establishing through cloud platform 30 that the operation speed is faster, the bigger control center of memory space, further promote the efficiency of storage intelligent management work.

step 304: determining a first wake-up time and a first wake-up signal strength when the electronic tag 10 is woken up;

the strength of the first wake-up signal is determined, other information does not need to be additionally added in the first wake-up signal, the setting or configuration requirements on the transmitting device can be simplified, and the operation difficulty or the equipment cost is reduced.

Step 306: determining a first preset intensity corresponding to the intensity of the first wake-up signal;

a plurality of preset intensities are prestored in the system, after the first awakening signal is received and the intensity of the first awakening signal is determined, the first preset intensity corresponding to the first awakening signal can be determined through simple size comparison, and the judging mode is simple, convenient and efficient.

Step 308: determining a first preset position corresponding to the first preset intensity according to the first preset intensity;

step 310: determining the position of the object at the first awakening moment according to the first preset position;

the preset strength corresponding to each preset position is prestored in the system, and the preset position, namely the position of the object, can be quickly determined as long as the preset strength corresponding to the strength of the received wake-up signal is determined, so that the mode of determining the position of the object is quick and simple.
