A communication channel switching method for dual communication modules

Abstract

The present invention relates to a method for switching communication channels of dual communication modules, comprising the following steps: S01: after the system is powered on and initialized, determine which communication module is currently used, and power on the current communication module; S02: determine the current communication module Whether the module networking has timed out, if not timed out, then normal network use, if timed out, then determine whether the automatic switching function is turned on, if turned on, then enter step S03, if turned off, return to step S02; S03: record the status information of the current communication module, and It is judged whether the current communication module is repeatedly switched, if it is repeatedly switched, the automatic switching function is turned off, and the target communication module is powered on, and if it is not repeatedly switched, the target communication module is powered on. The invention adds a secondary communication module to the intelligent door lock, and switches to another communication module when one of the communication modules has no network, so as to make full use of the advantages of the dual communication modules.

Description

technical field [0001] The invention relates to the technical field of intelligent door locks, in particular to a method for switching communication channels of dual communication modules. Background technique [0002] At present, the field of smart door locks in China is developing rapidly, and the communication technology of smart door locks is becoming more and more diversified. With the maturity of NBIOT (Narrow Band Internet of Things, narrowband Internet of Things) technology, its low power consumption, large capacity, and wide coverage are gradually favored by smart door locks. [0003] The Chinese patent application publication number CN108242097A discloses a smart door lock system based on narrowband Internet of Things technology, including smart door locks, service background, mobile phone APP client and PC system management client. Under the premise of low power consumption, the management and real-time monitoring of the door body, locks and battery status are re...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: NBIOT signals are susceptible to environmental interference, and it is impossible to ensure that every area can be quickly connected to the NBIOT core network, and there may even be a situation where the network cannot be connected for a long time. When the NBIOT module searches the network in the active state , the power consumption is relatively large. When the network is not good, the search time is longer, and the time in the active state is longer, which consumes more power, which has a great impact on the timeliness and power consumption of communication.
