Referring to fig. 2, fig. 2 is a schematic flow chart of a method for networking based on an electronic price tag according to another embodiment of the present invention. In the present embodiment, a plurality of gateways are involved, and the execution agent is represented by a home gateway in order to distinguish the gateways.
The differences between the present embodiment and the embodiment corresponding to fig. 1 are S202 to S203, S205, in the present embodiment, S201 and S204 are completely the same as S101 and S102 in the embodiment corresponding to fig. 1, and specific reference is made to the description related to S101 and S102 in the embodiment corresponding to fig. 1, which is not repeated herein. It should be noted that S205 is juxtaposed with S203-S204, and S205 is not executed after S204. The specific implementation is subject to the actual situation, and is not limited thereto. S202-S203, S205 are specifically as follows:
s202: sending a query request to a gateway in the group; the query request is used for querying whether the gateway receives the heartbeat packet.
The gateways in the group refer to other gateways in the same local area network as the local end gateway, and a user can configure each gateway in advance so that the gateways establish communication connection in the same local area network. The query request is used for querying whether other gateways in the group receive the heartbeat packet broadcasted by the electronic price tag.
It should be noted that the electronic price tag here refers to an electronic price tag corresponding to the identification information acquired by the home gateway at this time. The gateway sends a query request to other gateways in the group, specifically, the local gateway analyzes the acquired heartbeat packet, extracts data contained in the heartbeat packet, and generates the query request based on the extracted data. I.e. what data is contained in the heartbeat packet and what data is correspondingly contained in the query request. For example, a heartbeat packet may include: the query request also correspondingly comprises data such as identification information of the electronic price tag, the type of the electronic price tag, display identification information of content displayed on the current interface of the electronic price tag, a channel where the electronic price tag is located and the like.
The local gateway sends the inquiry request containing the data to other gateways in the group, and when the other gateways receive the inquiry request, the other gateways inquire whether the data contained in the inquiry request exist in the respective gateways. If the same data is found in a certain gateway in the group, the gateway in the group receives the heartbeat packet broadcasted by the electronic price tag; if a certain gateway in the group does not find the same data, it indicates that the gateway in the group does not receive the heartbeat packet broadcast by the electronic price tag.
Further, in order to increase the query rate, the data contained in the query request may be reduced. Specifically, when the home gateway generates the query request, only part of data in the heartbeat packet, such as the identification information of the electronic price tag, may be extracted. And sending the query request containing the identity identification information to other gateways in the group, and querying whether the identity identification information of the electronic price tag exists in each gateway when the other gateways receive the query request. If the identity identification information of the electronic price tag is found in a certain gateway in the group, the gateway in the group receives the heartbeat packet broadcasted by the electronic price tag; if a certain gateway in the group does not find the identity identification information of the electronic price tag, it indicates that the gateway in the group does not receive the heartbeat packet broadcast by the electronic price tag.
When the query result is that no other gateway in the group receives the heartbeat packet, executing S203-S204; when the query result is that any other gateway in the group receives the heartbeat packet, S205 is executed.
S203: when the query result returned by the gateway based on the query request is that the heartbeat packet is not received, sending processing prompt information to the gateway; and the processing prompt information is used for prompting the gateway to forbid processing of the heartbeat packet.
After receiving the query request, the gateways in the group query the data in the respective gateways according to the data contained in the query request, and when a certain gateway in the group queries the data, the gateway in the group receives the heartbeat packet broadcasted by the electronic price tag; when a gateway in the group does not inquire the data, the gateway in the group does not receive the heartbeat packet broadcast by the electronic price tag. And when the gateways in the group do not receive the heartbeat packet broadcasted by the electronic price tag, generating a query result without receiving the heartbeat packet based on the query request, and returning the query result to the local-end gateway.
The local gateway returns the inquiry results based on the inquiry request that the heartbeat packet is not received, and the inquiry results that the heartbeat packet is not received are returned to the local gateway. At this time, the home gateway transmits processing prompt information to other gateways in the group. Wherein the processing prompt information is used for prompting other gateways in the group to prohibit processing the heartbeat packet. After receiving the processing prompt information sent by the local gateway, the other gateways in the group do not perform any processing on the heartbeat packet even if the heartbeat packet is subsequently received, do not perform any processing on the electronic price tag for sending the heartbeat packet at the same time, and do not establish communication connection with the electronic price tag for sending the heartbeat packet.
When all query results returned by the home gateway based on the query request do not receive the heartbeat packet, after sending the processing prompt information to other gateways in the group, executing S204, where S204 is completely the same as S102 in the embodiment corresponding to fig. 1, and please refer to the description related to S102 in the embodiment corresponding to fig. 1, which is not described herein again.

And when the other gateways in any group receive the heartbeat packet based on the query result returned by the query request, the home terminal gateway does not process the heartbeat packet and does not establish communication connection with the electronic price tag. It can be understood that, as long as any one of the other gateways in the group returns a query result based on the query request as having received the heartbeat packet, the home gateway does not process the heartbeat packet and does not establish a communication connection with the electronic price tag.
Specifically, after receiving the query request, the gateways in the group query the data in their respective gateways according to the data included in the query request, and when any one of the gateways in the group queries the data, generate a query result that has received the heartbeat packet, and return the query result to the home-end gateway. At this time, the home gateway does not process the heartbeat packet, that is, the home gateway does not perform any processing on the heartbeat packet, for example, does not perform processing operations such as analysis, acquisition, compression and the like on the heartbeat packet; nor establish a communication connection with the electronic price tag. Correspondingly, the gateway which has received the heartbeat packet as a query result can analyze, acquire, compress and the like the heartbeat packet, and establish communication connection with the electronic price tag broadcasting the heartbeat packet.
It should be noted that, the query result is the gateway that has received the heartbeat packet, a method for processing the heartbeat packet is the same as a method for processing the heartbeat packet by the home-end gateway, and a method for establishing a communication connection with an electronic price tag that broadcasts the heartbeat packet is the same as a method for establishing a communication connection between the home-end gateway and the electronic price tag, which may specifically refer to specific implementation processes of S101 and S102 in the embodiment corresponding to fig. 1, and details thereof are not repeated here.
It should be further noted that, when the other gateways in any group return a query result based on the query request that the heartbeat packet has been received, the home gateway does not process the heartbeat packet and does not establish a communication connection with the electronic price tag. At this time, the home gateway may monitor the predetermined channel again, and wait for a new heartbeat packet.
