Detailed Description
To further illustrate the various embodiments, the invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1, the invention discloses a method for positioning an electronic price tag, comprising the following steps:
a1, arranging a resistance wire and a lead wire on each layer of the shelf along the length direction of the layer, and sequentially connecting the resistance wires on each layer in series through the lead wires of each layer.
Specifically, in this embodiment, the resistance wire is made of a copper foil material, and may be manufactured by using an existing circuit board processing process, which is easy to manufacture and has a low cost.
In order to improve the positioning accuracy, it is necessary to improve the resistance value of the resistance line per unit length along the length direction of the layer, for this reason, in this embodiment, the structure of the resistance line is preferably a structure in which a plurality of oblique waveform structures with one open side are sequentially open and alternately arranged up and down along the length direction of the guide rail, so that the resistance value per unit length of the resistance line along the length direction of the layer is maximized, and by adopting this structure, the electrical contact effect between the voltage reading port and the resistance line can be improved, and good electrical contact can be achieved, and of course, in other embodiments, the resistance line can also be formed by other back-and-forth bending structures such as a square wave, a sawtooth wave.
In this embodiment, the conductive wire is preferably made of a copper foil material, and may be manufactured by using an existing circuit board processing technology, which is easy to manufacture and low in cost. The wire is of a linear structure and is arranged in parallel with the resistance wire at intervals, so that the circuit structure is simple and easy to realize.
And A2, applying a constant voltage source to the resistance wire and the lead wire after series connection.
Specifically, one end of the resistor line and one end of the conducting wire after being connected in series are connected to a reference potential, and in this embodiment, preferably, the other end of the resistor line and the conducting wire are connected to an output end of the constant voltage source.
The constant voltage source has the advantages over the constant current source: the resolution of AD can be fully utilized by the shelf rows with different layers. The detailed description is as follows: when 8 layers or 4 layers are used for the shelf, the cross voltage on the resistance wires connected in series is fixed (such as 3.3V); the constant current is constant current, and when the layer number is small, the voltage of the uppermost layer is only about 1.5V. The constant voltage top layer is always 3.3V and in any case the maximum resolution of AD can be used to locate the electronic price tag.
And A3, acquiring a voltage A on the resistance wire and a voltage B on the lead wire corresponding to the position of the electronic price tag through the electronic price tag, acquiring the layer position of the layer where the electronic price tag is located through the voltage B, and acquiring the transverse position of the layer where the electronic price tag is located through the difference value of the voltage A and the voltage B.
Specifically, because the resistance of the wire is small, the voltage B on the wire at different positions of the same layer is substantially the same, so the layer position (i.e., the layer number) of the layer where the electronic price tag is located can be converted through the voltage B, and because the voltage values at various positions on the resistance wire are different, the transverse position (i.e., the layer number) of the layer where the electronic price tag is located can be converted through the difference between the voltage a and the voltage B.
Because the resistance value of every resistance line all can have certain error, consequently, if adopt many resistance lines directly to establish ties and fix a position, the error of every resistance line will add up, can make the voltage error on the resistance line of keeping away from the ground end bigger and bigger, lead to fixing a position inaccurately. The layer position (namely the layer number) of the layer where the electronic price tag is located through the voltage B on the conducting wire, the transverse position (namely the layer number) of the layer where the electronic price tag is located is obtained through the difference value of the voltage A and the voltage B, error accumulation of a plurality of resistance lines can be avoided, and the locating accuracy is improved.

The electronic price tag 1 uploads the ID and the library bit (the position of the several layers) automatically identified by the voltage of the resistance wire 21 and the conducting wire 22 at the detected position to the base station 3, and the base station 3 sends the ID and the library bit to the background server 4 through the router 6.
1.3. The handheld terminal 5 binds the shelf number, the ID of the electronic price tag 1 and the commodity bar code, the goods are automatically uploaded to the background server 4, and the background server 4 automatically generates a shelf diagram (a shelf layout diagram).
Secondly, aiming at a new store, a mode of newly installing electronic price tags and then placing commodities is realized, and commodity information is customized through a background:
2.1. the exhibitor can directly design the layout in the background or import the commodity display layout drawing to form a visual grid drawing (shelf row drawing) and send the visual grid drawing to the handheld terminal 5.
2.2. After the base station 3 and the guide rail 2 are well distributed, site constructors confirm the quantity and distance of the electronic price tags 1 placed on each layer of each shelf according to the layout of the handheld terminal 5, bind the ID and shelf number of one of the price tags 1 on the handheld terminal 5, and upload the ID and shelf number to the background server 4.
2.3. The background server 4 downloads the commodity information to the corresponding electronic price tags 1 in batches according to a preset shelf chart (shelf ranking chart).
2.4. The tally clerk puts the commodity according to the commodity information displayed by the electronic price tag 1, and the handheld terminal 5 can provide a function of quickly checking the commodity placement correctness so as to prevent the commodity from being misplaced.
When the tally personnel exchange the electronic price tags 1 at will (exchange up and down and exchange left and right), the electronic price tags 1 automatically identify the change of the storage positions through detecting the voltage of the resistance lines 21 and the conducting wires 22 at the positions, and send the change to the background server 4, the background server 4 carries out price tag displacement early warning, informs managers and other actions, so that the position monitoring and locking of the electronic price tags (commodities) on the goods shelf are realized, the tally personnel are prevented from buying and selling gold layers privately, the storage positions of the commodities are adjusted randomly, and a brand new solution is provided for the retail internet of things.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
