Problems solved by technology

When the wireless channel is disconnected, these configuration processes can only be realized by the operator through commands on the debugging interface (serial interface), and this can only be achieved with a certain background in wireless network technology. Difficult, almost impossible, for the vast majority of consumers of IoT home devices

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] like figure 1 As shown, the present invention is a method for re-connecting after network disconnection based on the embedded Wi-Fi module of the Internet of Things.

[0027] like figure 2 As shown, the embedded WIFI module adopts a low-power embedded WIFI module, including a hardware part and a software part. The hardware part includes a microcontroller chip 1, a WIFI chip 2, a program memory chip 3, a filter 4, a first crystal oscillator 5, The second crystal oscillator 6 and the power switch tube 7, the WIFI chip 2 and the microcontroller chip 1 are connected by data signals, the microcontroller chip 1 and the program memory chip 3 are connecte...

Abstract

The invention discloses a network breakdown re-access method based on an internet of things embedded Wi-Fi module. The method comprises the steps that the Wi-Fi module is powered on in an STA mode; whether a designated router is searched for or not is judged, and if the designated router is searched for, the Wi-Fi module has access to the designated router; if the designated router is not searched for, the module waits for a while, is automatically switched to an AP mode, and works for a while in the AP mode, whether the designated router is searched for or not is continuously judged, and if the designated router is not searched for, the steps are continuously circulated; if the designated router is searched for, the module is switched back to the STA mode and has access to the designated router. Due to an outage or a network breakdown or poor signals, the router can not be connected with the internet. When the power grid is restored and reconnection is required, the technical scheme is adopted, the complexity caused when home use consumer products like a smart home deal with the Wi-Fi network faults is greatly reduced, and the most critical problem of the popularization of an internet of things Wi-Fi device is solved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a method for reconnecting after network disconnection based on an embedded Wi-Fi module of the Internet of Things. Background technique [0002] The Internet of Things revolution is enabling more and more new devices to connect wirelessly to home networks and the cloud. However, for most of these terminal devices without keyboards or touch screens, such as home appliances, lights, thermostats, treadmills, electronic scales, etc., when these products work in the wireless base station (STA) mode, the wireless router is powered off After the network connection is interrupted due to reasons such as poor signal or poor signal, how to make it successfully reconnect to the Wi-Fi network is a huge obstacle preventing it from becoming a widely deployed connected home product. For these products working in the wireless base station (STA) mode, if they want to re-connect to ...
