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
The invention belongs to the technology of Internet of things field, particularly a kind of suspension based on the embedded Wi-Fi module of Internet of Things cut-in method again.
Background technology
The Internet of Things revolution makes more new equipment be able to be connected to family expenses networking and high in the clouds with wireless mode.Yet these terminal equipments that there is no keyboard or touch-screen for great majority, as household appliances, lamp, thermostat, treadmill, the equipment such as electronic scale, when these products that are operated under wireless base station (STA) pattern, after encountering the former thereby network disconnecting that causes such as wireless router outage or poor signal, how making its success again be connected to Wi-Fi network is but to hinder it to become the huge obstacle that widespread deployment connects homebrew.Be operated in these products under wireless base station (STA) pattern, want accessing Internet network again, must at first complete network configuration process, this comprises the wireless router that selecting properly is to be accessed, set cipher mode and cryptographic algorithm, then input correct password, last ability access network, passage connects.These layoutprocedures in the situation that radio channel disconnect, can only in the upper mode by order of debugging interface (serial line interface), just can realize by operating personnel, and this is need to have certain radio network technique background just can realize, exhausted large a part of consumer group for the Internet of Things housed device, very difficult, can realize hardly.
Summary of the invention
In order to address the above problem, the invention provides a kind of suspension based on the embedded Wi-Fi module of Internet of Things cut-in method again.
A kind of suspension based on the embedded Wi-Fi module of Internet of Things in the present invention is cut-in method again, it is characterized in that:
The S1:Wi-Fi module powers on the STA pattern;
S2: judge whether to search Designated Router: as do not search, S3 turned; As search, turn S7;
S3: wait for a period of time, module automatically switches to ap mode;
S4: module is worked a period of time under ap mode;
S5: judge whether to search Designated Router: as search, S6 turned; As do not search, turn S4;
S6: module is switched back the STA pattern;
S7: module is connected into Designated Router.
In such scheme, described ap mode is the wireless access dot pattern, is the Centroid of a wireless network.
In such scheme, described STA pattern is the wireless site pattern, is the terminal of a wireless network.
In such scheme, a period of time in described S3 is one minute.
In such scheme, a period of time in described S4 is one minute.
Advantage of the present invention and beneficial effect are: the invention provides a kind of suspension based on the embedded Wi-Fi module of Internet of Things cut-in method again.The present invention compared with prior art, has the following advantages and beneficial effect:
1, suspension of the present invention cut-in method again, can reduce to greatest extent the operation of manpower intervention, and the internet of things equipment (as router outage or damage, router is changed new password) in any suspension situation that guarantees to be operated under the STA pattern can correctly take back network.
2, suspension of the present invention cut-in method again, make to lose the STA equipment that network connects, and ap mode can automatically switch back.Thereby provide a wireless intervention passage easily, and realize that (intelligent terminal or PC are operated in the STA pattern for point-to-point configuration to this Wi-Fi module, and the Wi-Fi module is operated in ap mode, can directly match and carry out wireless connections), greatly reduced configuration step and the complexity of Wi-Fi.
3, suspension of the present invention cut-in method again, make to be operated in the internet of things equipment under ap mode, search Designated Router that can loop cycle.For example, as again searched Designated Router (this router powers on again or repairs), this equipment STA pattern that can automatically switch back, and re-establish and be connected with this Designated Router.Whole differentiation process all completes automatically, without any operation of manpower intervention.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the suspension of the present invention flow chart of cut-in method again;
The hardware system block diagram that Fig. 2 is the embedded WIFI module of the present invention.
In figure: 1, microcontroller chip 2, WIFI chip 3, program storage chip 4, filter

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention more clearly is described, and can not limit the scope of the invention with this.
As shown in Figure 1, the present invention is a kind of suspension based on the embedded Wi-Fi module of Internet of Things cut-in method again.
As shown in Figure 2, embedded WIFI module adopts low-power-consumption embedded WIFI module, comprise hardware components and software section, hardware components comprises microcontroller chip 1, WIFI chip 2, program storage chip 3, filter 4, the first crystal oscillator 5, the second crystal oscillator 6 and power supply switch tube 7, WIFI chip 2 adopts data-signal to be connected with microcontroller chip 1, microcontroller chip 1 adopts Serial Peripheral Interface (SPI) to be connected with program storage chip 3, WIFI chip 2 is connected with power supply switch tube 7 respectively with microcontroller chip 1, WIFI chip 2 is connected with the first crystal oscillator 5 with filter 4 respectively, microcontroller chip 1 is connected with the second crystal oscillator 6,
Software section comprises module interface administrative unit, application program module, web page server, miniaturization ICP/IP protocol stack, WIFI driver module, bottom hardware interface driver and real time operating system module, the real time operating system module is as framework, and module interface administrative unit, application program module, web page server, miniaturization ICP/IP protocol stack, WIFI driver module and bottom hardware interface driver are integrated on the real time operating system module.
Use the combination of low-power-consumption embedded WIFI module hardware part and software section, can realize very easily this method:
The S1:Wi-Fi module powers on the STA pattern;
S2: judge whether to search Designated Router: as do not search, S3 turned; As search, turn S7;
S3: wait for a period of time, module automatically switches to ap mode;
S4: module is worked a period of time under ap mode;
S5: judge whether to search Designated Router: as search, S6 turned; As do not search, turn S4;
S6: module is switched back the STA pattern;
