The general AP devices can support the wireless bridging function. When the user is in use, the user needs to enter the device management interface to manually perform a series of operations to complete the bridging. Generally, the manual operation of the user takes at least one minute, and if the number of the devices is large, the consumed time is increased along with the increase of the number of the devices, which undoubtedly increases the use time of the user and brings inconvenience to the user. In addition, the user always performs repeated actions in the operation process, and the operation is relatively complicated and inflexible.

Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
As shown in fig. 2, a point-to-multipoint automatic bridging method includes the following steps:
s1, each AP device starts a primary SSID and a corresponding secondary SSID;
s2, the AP device scans wireless signals of other surrounding AP devices, if a secondary SSID of one AP device is scanned and a corresponding primary SSID is not encrypted, the mac address of the scanned AP device is compared with the mac address of the AP device, and if the mac address of the scanned AP device is larger than the mac address of the AP device, the AP device is set to a STATION mode and is bridged to the scanned AP device; and if the mac address of the scanned AP equipment is smaller than the mac address of the AP equipment, the AP equipment is used as an AP mode to encrypt the main SSID of the AP equipment.
As shown in fig. 2, the point-to-multipoint automatic bridging method provided by the present invention specifically includes the following processes:
1. after the AP equipment is restored to the factory setting, two SSIDs, namely a primary SSID and a secondary SSID, are started, and the secondary SSID is named specially;
2. after being started, the AP device scans surrounding wireless signals in the background, and the following situations can be classified:
a. only one specially named secondary SSID is scanned, and the corresponding primary SSID is not encrypted; then the mac address of the device is compared to the size of its mac: if the mac address of the equipment is larger than the mac address of the equipment, setting the equipment into a static mode and bridging the equipment; if the mac address of the equipment is smaller than the equipment, the equipment is used as an AP mode to encrypt the main SSID of the equipment;
b. scanning one or more special SSIDs, only one corresponding main SSID is encrypted, and directly setting the SSIDs to a STATION mode to bridge to encrypted equipment;
c. if the special SSID is not scanned, no operation is performed;
d. scanning a plurality of special SSIDs, wherein the corresponding main SSIDs are not encrypted, or more than one of the corresponding main SSIDs are encrypted, and no operation is performed at the moment;
3. the indicator light of the device may flash during the process of starting scanning, and if the device is in the AP mode and there is a client connection, the indicator light may be set to a normally on mode, indicating that the one-to-one bridging process is completed, and if the AP device is in the client mode, the indicator light may flash all the time.
4. If no special SSID is scanned all the time, the device will not be scanned within one minute of factory reset.
5. After one-to-one bridging is completed, the device in the AP mode starts timing for 3 minutes, keeps the starting state of the secondary SSID and waits for being bridged by other APs;
6. and repeating the processes 1 and 2 in the starting process of the rest devices within 3 minutes, and smoothly bridging to the device in the AP mode, wherein the one-to-many automatic bridging is completed.
An AP device typically has two modes, an AP mode and a STATION mode. The special SSID name used in bridging is a fixed string plus its mac address, which ensures that the name is not duplicated. The password encrypted by the primary SSID is set to a value associated with the mac address, which ensures that the password is immediately available after being scanned by another device.
As shown in fig. 1, the operation method of the point-to-multipoint automatic bridging method provided by the present invention includes the following steps:
1. a user powers on and resets two devices at the beginning (more than two reset devices cannot exist in the surrounding environment);
2. when the indicator lights of the two devices start to flash, the automatic bridging process is started;
3. wait for a maximum of one minute, with the indicator light of one device becoming constantly on. If one minute is exceeded, no indicator lamp becomes normally on, the automatic bridging fails, and the resetting and the re-operation are needed;
4. when one equipment indicator lamp is turned on, any multiple equipment can be reset simultaneously within 3 minutes or in batches;
5. the device which is just reset can flash after being started, and if the indicator light is still in a flashing state after one minute, the one-to-many automatic bridging is finished. Otherwise, the automatic bridging process is abnormal (for example, the power-off of the normally-on device can result in the failure of bridging success).
As shown in fig. 2, the functional design flow of the point-to-multipoint automatic bridging method provided by the present invention is as follows:
1. the equipment which is recovered from factory settings can start the secondary SSID after being powered on, and the indicator light is set to be in a flashing state;
2. the device starts scanning for surrounding radio signals for a maximum of 1 minute. If the time exceeds 1 minute, the secondary SSID is turned off and the indicator light is turned off, and the automatic bridging process is ended;
3. if no special SSID is scanned, scanning continues. When the special SSID is scanned, the corresponding main SSID name can be obtained;
4. if one or more corresponding primary SSIDs are available, but only one is encrypted, setting the equipment into a STATION mode, closing the secondary SSID, and then encrypting and bridging the SSID;
5. if the number of the corresponding main SSIDs is one and only one, and the corresponding main SSIDs are not encrypted, judging the mac address corresponding to the SSID and the size of the mac address of the equipment;
6. if the mac address of the equipment is smaller than the mac address of the corresponding primary SSID, setting the mac address of the equipment to a STATION mode, and closing the secondary SSID;
7. if the mac address of the device is greater than the mac address of the corresponding primary SSID, the device is set to the AP mode, and fig. 3 shows a processing sub-flow thereof.
As shown in fig. 3, the sub-process of setting the AP device to the AP mode according to the point-to-multipoint automatic bridging method provided by the present invention is as follows:
1. setting the equipment into an AP mode, and encrypting a main SSID;
2. judging whether a client is connected or not, if no client is connected all the time within one minute, turning off the secondary SSID, turning off an indicator light of the equipment, and ending the sub-process;
3. if the client is successfully connected within one minute, the indicator light is set to be normally on;
4. and after waiting for 3 minutes, closing the secondary SSID, and completing automatic bridging.
The ❶ and ❷ illustrations shown in FIGS. 2 and 3 are as follows:
❶, the naming rule of SSID is that the fixed character string is added with the mac address of the equipment, and the difference of the mac address between the primary SSID and the secondary SSID is only 1, so the primary SSID can be obtained according to the secondary SSID;
❷ the encryption key of the primary SSID is a value calculated from its mac address using a fixed algorithm, such as the md5 algorithm.

1. automatic bridging is realized, and the bridging function of the equipment is simple and convenient to operate and easy to use. Originally, a user can complete the bridging function only by carrying out operation of multiple steps on an equipment management interface, and after the method and the device are used, the user only needs to reset the equipment. The plurality of operation steps are simplified into only one operation step, so that the use difficulty of a user is greatly reduced, the operation steps are simplified into a great variety, and the bridging function is simple and easy to use.
2. The bridging among dozens of devices is more rapid, and the time consumption of a user is controlled within 30 seconds and 4 minutes at most.
