In one embodiment, the identity information may include: the number and identification of the electronic price tag; the operating parameter information may include: the identification, the working channel and the electronic price tag type of the group to which the electronic price tag belongs; the operating state information may include: a data receiving state of the electronic price tag, a display state of the electronic price tag screen, and temperature information of an electronic price tag installation environment.
During specific implementation, the identity information, the working parameter information and the working state information can be stored in the electronic price tag in advance, and can also be information obtained in real time, for example, whether the display state of the electronic price tag screen is normal or not, or a tiny temperature sensor is arranged in the electronic price tag, and the temperature information of the installation environment of the electronic price tag is sensed in real time. Therefore, the electronic price tag can also transmit the real-time working state information of the electronic price tag and the information sensed in real time.
In specific implementation, in order to solve the technical problem that information of an electronic price tag cannot be tracked, a safe heartbeat mechanism is introduced in the embodiment of the present invention, when an electronic price tag system is installed in a supermarket, the electronic price tag reports information of the electronic price tag according to a certain mechanism (preset condition), and the information of the electronic price tag may include: the identity information, the working parameter information and the working state information are collected by the base station, the electronic price tag information is collected and sent to the server, namely the electronic price tag is installed, the electronic price tag information (the identity information, the working parameter information and the working state information) can be sent out in a heartbeat package mode in the working process of the electronic price tag, and the server can know the working state of the electronic price tag at any time according to the information of the heartbeat package and can track the information of the electronic price tag at any time.
The preset condition for sending the electronic price tag heartbeat packet by the electronic price tag can be various, and a few examples are described below.
First, in one embodiment, the electronic price tag is specifically configured to periodically transmit electronic price tag heartbeat packets.
In a specific implementation, the electronic price tag may send the electronic price tag heartbeat packet in a timing manner, for example, once every 10 minutes, and the like. The method is suitable for the use process of the electronic price tag after the electronic price tag is installed, so that the server can know the working state of the electronic price tag at any time, can track information of the electronic price tag at any time, and updates the information of the electronic price tag sent in real time into the server.
Secondly, in an embodiment, the electronic price tag is specifically configured to send the electronic price tag heartbeat packet after receiving report notification information sent by a server.
In a specific implementation, the electronic price tag may report information of the electronic price tag after receiving a notification from the server, for example, before the electronic price tag is used, the server sends an information reporting notification to all the electronic price tags through the base station, the notification reports the information of the electronic price tag, after the electronic price tag receives the notification, the information of the electronic price tag is reported to the server, and the server stores the information of the electronic price tag.
Thirdly, in one embodiment, the electronic price tag is specifically configured to send the electronic price tag heartbeat packet under the control of the magnetic control switch.
In specific implementation, the electronic price tag may include a magnetic switch, and after an operator manually triggers the magnetic switch, the electronic price tag may transmit information of the electronic price tag. Of course, the magnetic switch may be: when the electronic price tag is turned on, the total magnetic control switch is triggered, and the electronic price tag can forward the information of the electronic price tag to the server through the base station for storage.
In the use process of the conventional electronic price tag, the inventor finds that the business excess is mostly chain business, so that the problem of stock exchange of the price tag among different stores of the same customer exists, and the electronic price tag is the asset of the customer, so that the management of the electronic price tag is disordered, and the asset is lost.
Since the inventor considers this technical problem, in one embodiment, the electronic price heartbeat package further includes: a first security code representing a restricted use area of the electronic price tag, the first security code representing a store;
the server is specifically configured to match the first security password with a pre-stored security password when the electronic price tag heartbeat packet is received for the first time, and store the identity information, the working parameter information and the working state information or update the stored identity information, the working parameter information or the working state information when the first security password is consistent with the pre-stored security password.
In specific implementation, when the electronic price tag in the embodiment of the invention is taken from one store to another store for use, due to the difference of the first security passwords of the electronic price tag, when the electronic price tag is used in another store, the electronic price tag sends the electronic price tag heartbeat packet containing the first security password, the server of the store matches the received first security password according to the stored security password, and if the stored security password is not consistent with the received first security password, the server can send the electronic price tag invalidation notification message to the electronic price tag through the base station; the electronic price tag is also used for displaying the electronic price tag failure notification information. The electronic price tag cannot be used in the store. Therefore, the electronic price tag cannot be used in any store except the original store, the problem of 'goods mixing' of the store can be effectively controlled, the asset management of the store is improved, and loss is avoided. Meanwhile, the electronic price tag can be prevented from being stolen by setting the first security password.
In the use process of the existing electronic price tag, the inventor also finds that the electronic price tag has the same problem because the business surpasses and has the anti-theft problem, but the mechanism of the general anti-theft tag is different from the mechanism of the price tag, and the anti-theft tag has poor effect, so that the anti-theft effect is poor. Theft prevention here means that persons in other storefronts are prevented from stealing the electronic price tag of the store.
Since the inventor considers the technical problem, in one embodiment, the server is further configured to generate and store a second security password when the identity information, the operating parameter information and the operating state information are received for the first time;
the base station is also used for forwarding the second security password to the electronic price tag;
the electronic price tag is also used for storing a second security password; the second security code is used for representing the uniqueness of the electronic price tag in the limited use area;
the server is also used for matching the received second security password with the stored security password when receiving the electronic price tag heartbeat packet, and sending electronic price tag failure notification information to the electronic price tag through the base station when the received second security password is inconsistent with the stored security password;
the electronic price tag is also used for displaying the electronic price tag failure notification information.
During specific implementation, when the electronic price tag is transported to a customer site, and after a server and a base station are installed, before the electronic price tag is installed, in order to solve the problem that price tag information cannot be obtained, the electronic price tag information can be sent to the server through the base station at the first time in a safe heartbeat packet mode, the server can collect all information of the electronic price tag of a store, and can randomly generate a new safe password, namely a second safe password, so that the passwords of different stores and customers are different. The new security code (second security code) is sent to the electronic price tag by means of networking or updating packet, and the electronic price tag and the server both store the second security code. By the way, the system completes the collection process of the safety heartbeat (electronic price tag information, identity information, working parameter information, working state information and the like), and all electronic price tags of the store enter a normal working state. As the base stations are installed in all shops and no dead angle is covered, the price tags are taken to any position in the shop by the shop, the system can receive the safe heartbeat (electronic price tag information, identity information, working parameter information, working state information and the like) of the price tags, and effective price tag management and control can be realized.
The first security code represents a storefront and the second security code enables the electronic price tag to be unique at the storefront.
According to the anti-theft method, the electronic price tag is installed on the spot of a customer store, a certain loss proportion exists, the original anti-theft measures are insufficient in protection of the price tag, the anti-theft mode is changed for improving the anti-theft of the price tag, and based on the first safety password and the second safety password, the price tag is guaranteed to be unusable after leaving the store, so that the price tag enters a failure mode. When the price tag is taken to a store and the security password is updated (the second security password is generated), the electronic price tag has uniqueness which is the uniqueness associated with the store, and once the price tag is taken away from the store, the price tag cannot be used in any other environment due to the fact that the first security password and the second security password are inconsistent, and finally the electronic price tag is invalid.
In the use process of the existing electronic price tag, the inventor also finds that a one-dimensional code is arranged on the surface of the price tag, and the one-dimensional code is the identity information of the price tag, but due to space limitation, the one-dimensional code cannot be too long and cannot include all price tag working parameters. The identity information on the surface of the price tag can only be used for binding the price tag and the commodity. When price tags are bound with commodities, base stations are bound synchronously, ID information of the base stations needs to be input manually in the prior art, and therefore the implementation process is complex and difficult to operate.
In order to solve the technical problem, in one embodiment, the server is further configured to calculate signal strength of an electronic price tag heartbeat packet of the same electronic price tag sent by a plurality of base stations, and establish a binding relationship between the base stations and the electronic price tags according to a calculation result;
the base station is specifically configured to forward the electronic price tag heartbeat packet to the server according to the binding relationship.
In one embodiment, the server is specifically configured to: establishing a binding relationship between the base station which sends the electronic price tag heartbeat packet and the electronic price tag which sends the electronic price tag heartbeat packet, wherein the base station has the maximum signal intensity;
the base station is specifically configured to forward the electronic price tag heartbeat packet to the server according to the binding relationship.
In specific implementation, the electronic price tag information sent by the electronic price tag can be sent to the server through the base stations at the same time, the server can judge the signal intensity of the electronic price tag information sent by the base station, and can bind the base station corresponding to the strongest signal with the electronic price tag for sending the electronic price tag information according to ranking of the signal intensity, so that automatic binding is realized, manual input of the ID of the base station in the prior art is not needed, and the labor cost is saved.
As shown in fig. 2, when the electronic price tag 2 transmits the electronic price tag information again after the automatic binding, the electronic price tag information is transmitted through the base station 1 to which the electronic price tag information is bound. Of course, the server may consider the busy degree of the base station 1 in addition to the signal strength, if there are more electronic price tags for transmitting the electronic price tag information through the base station 1, it may consider to transmit through another base station 2, and the signal strength for transmitting the electronic price tag information through the base station 2 is not the strongest and may be ranked second, but the busy degree of the base station 2 is lower than the busy degree of the base station 1. Meanwhile, when the position of the product bound by the electronic price tag is changed by a tally clerk, the ID information of the base station does not need to be input manually, and the optimal base station (which can be optimal in signal intensity and busyness) can be found for the electronic price tag again through judgment of the server.
Compared with the technical scheme of manually inputting the ID information of the base station in the prior art, the technical scheme of automatic binding in the embodiment of the invention does not need to manually input the ID information of the base station, and can bind a proper base station for the electronic price tag at any time.
In one embodiment, the base station is embodied as a wireless access point AP.
