Description

Automatic numbering method for equipment based on SSID broadcast

Technical Field

The invention belongs to the technical field of electronic information, relates to an automatic numbering method for equipment, and particularly relates to an automatic numbering method for equipment based on SSID (service set identifier) broadcasting.

Background

At present, the traditional equipment number distribution method is carried out by adopting a mode of manually inputting instructions, and the equipment numbers are manually configured during production, debugging and installation so as to meet the serial requirements of the equipment on the numbers in use. The manual configuration equipment numbering workload is large, the efficiency is low, a large amount of labor cost is wasted, meanwhile, the error probability is high, and the conditions of numbering vacancy, numbering repetition, numbering error and the like occur occasionally. Once the device number is wrong, the use convenience is reduced, even the device is in failure, and the like.

Therefore, a method capable of solving the inconvenience of manual numbering of the equipment is urgently needed in the market, and is used for reducing the complexity and the configuration deployment difficulty of equipment numbering and avoiding the situations of numbering error, repeated numbering, discontinuous numbering and the like.

At present, many internet of things devices adopt a Wi-Fi mode to configure and link users, but a traditional Wi-Fi device only broadcasts a fixed SSID to the users when in use, and when the users own a plurality of devices at the same time, each device cannot be distinguished through the SSID. Generally, if a user uses a mobile phone, a computer, or other configuration device to access a Wi-Fi signal transmitted by an internet of things device, a plurality of devices use the same ESSID (extended service set identification code), which may cause link collision. The connection of a user can be randomly accessed into certain Internet of things equipment with a relatively strong signal, or the Wi-Fi access points with the same ESSID and different BSSIDs (basic service set identification codes) are considered as different AP access points of the same network to be merged and displayed, and the user repeatedly skips and roams in Wi-Fi signals of different equipment during connection. The user can not know which equipment is specifically accessed through the Wi-Fi information, and even can not be normally connected with the equipment for operation.

Some newer internet of things devices can add part of unique information of devices such as BSSID (basic service set identification code), MAC address, Serial Number (Serial Number) of the devices into SSID (service set identifier) of the devices for transmitting Wi-Fi access point signals, so that users can distinguish corresponding device access points and avoid the connected devices from entering a roaming mode.

Disclosure of Invention

The invention discloses an automatic numbering method for equipment based on SSID (service set identifier) broadcasting, which aims to solve the problems that equipment ESSID is not visual repeatedly, the equipment is numbered manually and the like. The method combines the SSID with the number of the equipment, can automatically complete the generation of the equipment number when in use, and configures part of the SSID as the equipment number.

The purpose of the invention is realized by the following technical scheme:

an automatic numbering method for equipment based on SSID broadcast comprises the following steps:

s1, when the equipment is started, scanning the SSID of the nearby access point;

s2, filtering the scanned access points with the same SSID head into a table;

s3, judging whether the access points contain the access points with the same SSID head; if not, go to step S4; if yes, go to step S5;

s4, executing step S7 after creating the access point with SSID as 1 serial number name;

s5, sequencing the access point serial numbers with the SSID heads;

s6, after the access point with the SSID serial number of the minimum vacant name or the next access point with the maximum serial number name is created, executing the step S7;

and S7, storing SSID information.

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

1. the method of the invention uses the SSID broadcast characteristic of Wi-Fi, when the device starts configuration, the SSID information broadcast by the former device is automatically searched, and the SSID broadcast information of the device is configured and deployed according to the scanned SSID information, thereby realizing the automatic and ordered grouping function of the device.

2. The method can reduce the complexity of equipment numbering, reduce the requirements on workers during equipment numbering, avoid various problems and accidents caused by wrong equipment numbering, avoid the waste of a large amount of manpower resources and manpower cost of equipment configuration personnel in heavy equipment numbering related work such as equipment numbering generation, equipment numbering burning, equipment numbering recording, equipment numbering verification and the like, and automatically complete equipment numbering work.

3. The method can avoid the problems that when the Wi-Fi access point is connected, the nearby Wi-Fi access points with a large number of same BSSIDs with different ESSIDs are used as an Extended Service Set (ESS) to be merged and displayed, and the Wi-Fi access points roam to other Wi-Fi access points in a connecting mode, so that the connection is stable and reliable, the phenomenon that the information such as an excessively random SSID, an MAC address and a serial number is used as a seed for SSID generation, and the phenomenon that a user is confused about the equipment access point due to the fact that the excessively random SSID access point name is generated can be avoided.

4. The method of the invention can realize automatic sequential marshalling among the devices, sort the devices according to the starting sequence of the devices, automatically scan and identify the prior devices by the later started devices, calculate and determine the marshalling number information of the devices, and add the devices into the whole device marshalling.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings, but not limited thereto, and any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention shall be covered by the protection scope of the present invention.

The invention provides an automatic numbering method of equipment based on SSID broadcast, as shown in figure 1, the method comprises the following steps:

s1, when the equipment is started, scanning the SSID of the nearby access point;

s2, filtering the scanned access points with the same SSID head into a table;

s3, judging whether the access points contain the access points with the same SSID head; if not, go to step S4; if yes, go to step S5;

s4, executing step S7 after creating the access point with SSID as 1 serial number name;

s5, sequencing the access point serial numbers with the SSID heads;

s6, after the access point with the SSID serial number of the minimum vacant name or the next access point with the maximum serial number name is created, executing the step S7;

and S7, storing SSID information.

When the method for automatically numbering the devices based on the SSID broadcast is used, the devices needing automatic numbering are sequentially started according to the numbering sequence defined by the requirement, firstly, the first started device cannot detect the existing device grouping, and the first started device is used as the first device of the device grouping to establish the device grouping. The second enabled device defines itself as device number two of the device group when the scan detects the device group created by device number one. The third enabled device defines itself as device group number three device when the scanning detects the device group access point information created by device number two. If the second equipment is closed for some reason, the serial number of the second equipment is vacant. The fourth enabled device defines itself as the second device of the device group or defines itself as the fourth device to complement the device group when the scanning detects the device group created by the first device. The equipment marshalling takes the starting sequence during configuration as a serial number, so that the problems of large workload, low efficiency and high error probability of configuring equipment serial numbers can be solved, and the situations of error numbering, repeated numbering, discontinuous numbering and the like are avoided.

Example (b):

when a user needs to connect to an SSID access point of a specific device during use, for example, the same access point name is adopted or the user cannot know which specific device among a plurality of devices sends an access point signal, the user with the random access point name cannot quickly and accurately find the SSID access point of the device to be connected when the devices are more, and the user needs to compare the random SSID, MAC address and serial number of the device word by word, which is time-consuming and labor-consuming. The roaming scheme for a device connection resulting from the same ESSID (extended service set identifier) used by an access point is shown in fig. 2. The access point name is too random to cause device connection confusion as shown in fig. 3. The schematic diagram of the SSID of the wireless access point of the device after applying the method of the present invention is shown in fig. 4. The invention uses the SSID broadcast characteristic of Wi-Fi, when the device is started, the SSID information broadcast by the former device is automatically searched, and the SSID broadcast information of the device is configured and deployed according to the scanned SSID information, thereby realizing the automatic and ordered grouping function of the device.
