Problems solved by technology

It can be seen that such a communication method is likely to generate a large number of invalid queries, which not only increases the burden on the ESL server, but also increases the service delay of the ESL with real service needs, and the ESL with service needs cannot be served due to various exception handling. This leads to low reliability, stability, and work efficiency of the ESL system, and also increases the useless power consumption of the ESL, resulting in a short service life of the ESL's own battery, requiring frequent replacement of new ESLs, and increasing investment costs.

Abstract

The invention discloses a data communication system and a communication method thereof, and an electronic shelf label system and a communication method thereof. The communication system comprises a wireless access device as a client and an ESL as a server. The communication method of the communication system comprises the following steps: scanning the corresponding ESL according to the destinationESL address; sending a service request to the ESL; and sending a display message to the ESL to update the display content. The ESLS comprises a data push source, a ESL server, a wireless access device, and an ESL. The communication method of the ESLS comprises the following steps: when the commodity information is needed to update, a commodity information message is sent to the ESL server and forwarded to the wireless access device; and the wireless access device sends a service request to the ESL after scanning the corresponding ESL according to the destination ESL address and sends the display message to the ESL to update the display content. The invention can improve the stability, reliability and the communication processing efficiency of the ESLS, and can make the ESL achieve the effect of low power operation and power saving; the invention can be widely used in the technical field of ESL.
