Description

Method for starting WiFi based on non-contact mode

Technical Field

The invention belongs to the technical field of WiFi starting, and particularly relates to a method for starting WiFi based on non-contact.

Background

With the development of science and technology, WiFi is always available in people's life, and mobile phones, computers, ipads and even wearable devices (terminal devices) have WiFi functions. However, with the expanding demand, wireless internet access devices (APs), such as routers, etc., are used to meet the needs of people, expand the WiFi transmission power, improve the wall-through technology of WiFi, etc., so that radio electromagnetic waves exist around the life of people all the time, and people feel that the health of the people is affected by the existence of more or less radiation, especially in a sleeping state.

The invention is needed, so some AP devices have developed a function of turning off WiFi, and a user may set a time period for turning off WiFi according to the needs of the user, for example, a time period of 23:00 to 6:00 is set to turn off WiFi, then WiFi is turned off in the time period, and a terminal device cannot search for a WiFi hotspot, so that on one hand, people can sleep without interference of WiFi, and on the other hand, there is a problem: if someday in this time slot, how do someone want to connect WiFi with terminal device for surfing the internet? This problem is also to be solved.

The existing methods have three kinds, and each method has certain problems.

The method comprises the following steps of: a computer is connected with a router to turn on WiFi, but the steps are too complicated;

the second method comprises the following steps of: some AP equipment is provided with a WiFi control key, WiFi can be started through the key, but the AP equipment needs to go to the position of a router to control, if the AP equipment is not in a room, the AP equipment runs to a next door to influence rest of other people, and the AP equipment is complicated;

the third method is controlled by a cellular network of the mobile phone: some APs support remote access, i.e. server control of APs connected through the cellular network of the handset, but this requires the cellular network, and if there is only one iPad, it cannot be implemented well.

Therefore, the method of the invention is to adopt one and simple operation to meet the requirements of people in order to remove the series of complicated and tedious modes.

Disclosure of Invention

The present invention is directed to a method for turning on WiFi in a contactless manner, so as to solve the problems mentioned in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

a method for starting WiFi based on non-contact mode comprises the following specific steps:

in the process of developing the AP, a function is added, the function is mainly started when a user sets WiFi to be turned off at fixed time, when the WiFi is turned off, a sending device is turned off through a software strategy, a receiving device of the WiFi is reserved, the WiFi can be turned off, the user cannot search the WiFi and cannot generate electromagnetic waves, and the purpose that the user sets the WiFi to be turned off at fixed time is also achieved; during the period of closing WiFi, the receiving module of AP can search surrounding broadcast information regularly;

(II) reserving a WiFi starting function interface when APP of the user terminal is developed, wherein the interface is started only during the WiFi closing period, otherwise, the function is not required to be started;

and thirdly, when the WiFi is closed, the user opens the WiFi hotspot of the terminal equipment, the terminal equipment enters the APP, and when the function of 'opening the WiFi' is clicked, the APP can send broadcast information through the hotspot of the terminal.

The broadcast information policy is detailed as follows:

1. the broadcast message comprises a section of encrypted ciphertext preset with the AP, the encryption mode is only known by the AP, namely after the AP receives the message, the AP successfully decodes the message to know that the message is a command for starting the WiFi sent by a user, so that the WiFi can be started, otherwise, the message is not considered;

2. presetting an unusual broadcast network segment, wherein the network segment is only known by an AP and a terminal APP; this is done in order to keep more people from knowing the broadcast message, which is then a password, in order to further increase security considerations;

3. a channel is also preset for message broadcasting, so that unnecessary information broadcasting is reduced on one hand, and a safety mechanism is added on the other hand.

Compared with the prior art, the invention has the advantages that:

1. the method of the invention is realized in a pure software mode without adding any hardware equipment, and does not need extra economic expense of users;

2. the method is designed at the angle of the user, and one-button simple operation is adopted, so that convenience is brought to the use of the user;

3. although the method of the invention adopts a very common mode of broadcasting, a multi-layer security mechanism is designed in the using process of the method to ensure the security of the user information.

Detailed Description

The technical solution of the present invention will be described in further detail with reference to specific embodiments.

The invention discloses an embodiment of a method for starting WiFi based on non-contact, which comprises AP service program development and terminal equipment APP development, wherein the AP service program development specifically comprises the following steps:

step 1: packaging a software function interface;

voidSet _ wifi _ send _ off (); // turn off WiFi Transmission device

voidSet _ wifi _ send _ on (); // turn on WiFi Transmission device

voidwifi _ timer _ on (); whether the WiFi timing function is started or not;

step 2: writing an application process, the rough software development framework is as follows:

the development of the terminal APP specifically comprises the following steps:

step 1, packaging a software interface;

void click wifi on check (); // click on WiFi function

voidConnect _ wifi _ check (); // WiFi of whether or not to connect corresponding AP

voidHotPoint _ on _ check (); // whether to connect to a mobile phone hotspot

voidaion _ boardcast (); v/timed broadcast WiFi on command

After a user opens a mobile phone APP, detecting whether a WiFi function is clicked to open or not;

step 2, a service program rough framework;

as shown in fig. 1, when the WiFi is turned off during the operation of the AP service program, the sending device is turned off by a software policy, and a receiving device of the WiFi is left, so that the WiFi is turned off; during the period of closing WiFi, the receiving module of AP can search surrounding broadcast information regularly; and if the received designated message is successfully decoded and verified, starting the WiFi sending device.

As shown in fig. 2, in the APP application phase of the user terminal, when the user is in the WiFi off period, the user opens the WiFi hotspot of the terminal device, enters the APP, and clicks the "WiFi on" function, the APP sends broadcast information through the hotspot of the terminal, and detects whether the corresponding APWiFi is connected.

The invention belongs to short-distance operation and is suitable for different types of terminal equipment; and the receiving and sending module of WiFi is used as an entry point, the original mode of starting WiFi is optimized, convenience is brought to users, and the common mode suitable for short-distance broadcasting is used, so that short-distance communication is realized.
