All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 2, a wireless connection method includes the following steps:
s1: the first wireless device and the second wireless device turn on a wireless connection mode.
As shown in fig. 4, the first wireless device and the second wireless device are devices having wireless connection functions such as bluetooth or WiFi, in this embodiment, the first wireless device is a barcode reading device capable of scanning barcodes, such as a handheld barcode scanning gun, a desktop barcode scanner, a mobile data terminal, a portable barcode scanner, and the second wireless device is a device having an electronic display screen, such as a notebook computer, a tablet computer, a mobile data terminal, and the like.
And wireless connection programs are arranged in the first wireless connection device and the second wireless connection device, and an operator clicks a program starting button to enable the devices to enter a wireless connection working state. The execution unit of the device can control the wireless switch state of the device according to the program, read the MAC code of the device, modify and display the wireless connection name of the device, execute searching and matching and perform other preset rules and flows.
S2: and the first wireless equipment generates a target name according to a preset rule and displays the target name and a local MAC address generating bar code on a local display screen.
In step S2, the target name generated each time a wireless connection is established is unique and not repeated.
As shown in fig. 5, in this embodiment, the first wireless device is a tablet computer, the second wireless device is a handheld code scanning gun, and the first wireless device executes a predetermined program to generate a hotspot name (SSID), which is a target name, according to a preset rule: ABCD 123. The preset rule can set different coding rules according to requirements, including length limitation, character type limitation and the like, and can also take the connection initiating time and the equipment model as part of the target name.
The first wireless device also reads a native MAC code, in this embodiment, the native MAC code is 28: F5:37:71:4B:20, and adds the generated target name ABCD123 to obtain a code word content: ABCD 12328: F5:37:71:4B:20, and the first wireless device generates a barcode according to the content of the code words and displays the barcode on a local display screen.
If the requirement on the safety is not high, only the MAC address of the first wireless equipment can be used as the code word content, in this case, fixed target names are required to be agreed in advance between the equipment, or the target names are generated according to the MAC address in the code word content by using a method agreed in advance.
Because the bar code scanning device including the handheld code scanning gun needs to scan the bar code frequently in the using process, in order to distinguish the set code from other bar codes related in the normal using process, some specific contents can be added in the code word content to be used as an identifier or some parameters (such as adding specific code marks, different code system types and the like) different from other bar codes used in the service flow can be added in the bar code generating process, so that the second wireless device can quickly judge that the bar code is the wireless connection function bar code.

S5: and the first wireless equipment and the second wireless equipment respectively generate authentication information according to the content of the bar code and a preset rule, wherein the rule is that the character string is converted into the authentication information participating in the wireless connection setting through an algorithm.
In the step S5, the authentication information is security information, including a bluetooth paired PIN code or a WiFi connection encryption authentication method and password.
The authentication is defined as the operation of inputting a PIN code to pair in the Bluetooth connection process, and the operation of setting an encryption authentication mode, a WiFi password and the like in the WiFi connection process. The authentication information is information related to safety in the wireless connection process and comprises a Bluetooth pairing PIN code, a WiFi encryption authentication mode, a WiFi password and the like. The authentication information generation rule is an algorithm agreed by the two devices in advance, and can be built in a factory stage or downloaded in a state that the devices are connected to an official party. The algorithm can generate authentication information through calculation according to the content of the bar code, and the algorithm can generate the authentication information through numerical operation and character conversion.
In this embodiment, according to the barcode content ABCD 12328: F5:37:71:4B:20, the authentication information generated by the authentication information generation rule is that the WiFi encryption mode is WPA2 and the password is 17B40282F 573. And the two pieces of equipment respectively change the WiFi encryption mode of the two pieces of equipment into the WPA2, and the second equipment sends the password to the first wireless equipment.
S6: and the first wireless equipment and the second wireless equipment exchange authentication information of both sides in a wireless signal transmission mode and carry out matching, and when the authentication information is matched with each other, connection is established, otherwise, connection is refused.
In this embodiment, the second wireless device receives the password sent by the first wireless device and compares the password with the password calculated by the local device, and the password is correct and the connection is successful.
In the step S6, after the authentication information is successfully matched, the second wireless device sends a request to the first wireless device to verify the MAC address, and compares whether the MAC address of the first wireless device is consistent with the MAC address in the barcode recorded in the step S3, if so, the connection is successful, otherwise, the connection is rejected.
In order to prevent other devices from being illegally or unintentionally wrongly connected by means of screen capture and the like, a MAC address verification stage can be added.
After the connection is successful, when a new device needs to be connected, the first wireless device and the second wireless device negotiate with each other whether to disconnect the current connection, and after the disconnection, the steps from S1 to S6 are executed again to complete the wireless connection of the new device.
According to the wireless connection method, the operation process of the equipment is simple and quick, the searching process does not need to be participated in too much manpower, and the accuracy and the high efficiency are realized; the authentication information is automatically generated by the equipment according to a preset rule, safety information such as a password and the like does not need to be recorded manually or input manually, and the safety is high.
