The server is specifically used for being responsible for access verification and realizing the binding of the user equipment application and the intelligent equipment; the server is generally deployed in a computer room, processes and analyzes uplink and downlink data through a script file, and communicates with the user equipment and the intelligent equipment through network connection.
The embodiment of the invention provides a network distribution method, which can be specifically executed by an intelligent device, and as shown in fig. 2, the method comprises the following steps:
s1, the intelligent device monitors the broadcast of the router and acquires the service set identification (ssid) signal.
In this embodiment, the smart device may record a channel corresponding to each ssid signal according to the obtained ssid signal. And then switching channels at specified time intervals until a specified number of data packets are received in the currently accessed channel. Wherein the wireless communication module of the smart device enters a Sniffer mode. For example: the intelligent device obtains a surrounding ssid signal through the wireless communication module entering the Sniffer mode, and records a related channel. And the intelligent equipment switches the channel every 300ms and monitors the empty packet. And if all the channels are switched and the appointed packet cannot be acquired, re-acquiring the channels and re-starting to switch the channels to monitor the data packet.
And S2, after acquiring the specified number of data packets from the ssid signal, accessing the current channel according to the acquired ssid signal.
Wherein the specified number of packets contain the same address tag, and the address tag points to the user equipment.
For example: after acquiring the specified number of data packets from the ssid signal, accessing the current channel according to the acquired ssid, including:
and detecting the number and the frame length of the data packets acquired from the ssid signals, and accessing the current channel when the specified number of data packets with the same frame length are acquired in an accumulated manner.
Specifically, the accessing the current channel when the specified number of data packets with the same frame length are obtained accumulatively includes: and accessing the current channel when the specified number of data packets with the same frame length are obtained in an accumulated mode and the frame length of the data packets is the shortest length. Such as: if the data packets with the same frame length are acquired for 6 times or more (the data packets contain address marks), the channel is locked, and the data packets are analyzed.
For another example: after acquiring the specified number of data packets from the ssid signal, accessing the current channel according to the acquired ssid, including:
and detecting the address marks of the data packets acquired from the ssid signals, and accessing the current channel when the specified number of data packets with the same address marks are acquired in an accumulated manner.
Specifically, when the specified number of data packets with the same address identifier are obtained in an accumulated manner, accessing the current channel includes: and when the specified number of data packets with the same frame length are obtained accumulatively and the frame length of the data packets is the shortest length, detecting whether the data packets with the basic frame length are received within a preset time length, and if so, accessing the current channel. Such as: and if the intelligent equipment acquires 10 data frames from the same user equipment and router in an accumulated mode, locking the channel. Within the next 2 seconds, if the data frames with the basic length can be acquired (for example, 20 shortest data frames with the same length are acquired in an accumulated mode), the data packet analysis is started, otherwise, the channel is switched.
And S3, analyzing the data packet received through the current access channel.
Wherein the data packet includes: and the user equipment sends a multicast packet and a broadcast packet to the router. Specifically, the data sending logic may be loaded by the user equipment: the user equipment simultaneously transmits a multicast packet (which may also be referred to as a multicast data frame) and a broadcast packet (which may also be referred to as a broadcast data frame) through the router at a designated period. And after the whole multicast packet and the broadcast packet are sent, judging whether the sending time exceeds the sending period or not, if not, continuing to send the whole multicast packet or the broadcast packet. Specifically, the data structure of the broadcast packet and the data packet is described as follows:
and the intelligent equipment acquires the transmitted information according to the length of the received broadcast packet sent by the router. For example: data sent by the router is mapped into 64 lengths after being processed by base64, for example: 0-25 parts of A-Z, 26-51 parts of a-Z, 0-9 parts of 52-61 parts of +:62,/: 63 and a tail part which are filtered. The base64 encoding table maps base64 encoded characters to 0-64 numeric values. The transmission format is a json string, and the entire json string is base64 encrypted before transmission.
For the multicast packet, 339.0.0.0-239.255.255.255 are locally manageable addresses. The upper 24 bits of the multicast MAC address are 0x01005e, the 25 th bit is 0, i.e. the upper 25 bits are a fixed value. The first 4 bits of the IP multicast address are 1110, representing a multicast identity, while only 23 of the last 28 bits are mapped to a MAC address. In the embodiment, 23 bits after the multicast ip address is adopted to construct data. Wherein, the characters are all visible characters, the range is 0-128, and 3 bytes of data can be sent each time. The transmission format is a json string and only the values are base64 encrypted before transmission.
And the user equipment automatically stops when the total time sent reaches the maximum timeout time (30 s by default, and can be set to 30s, 60s and 80s), and returns a message that the intelligent equipment fails to connect the router. When sending a data packet, the user equipment locally starts mdns, and when finding that there is a specified data packet (json format, data contains mac, product type number (pid), deviceid, that is, APP distribution network characteristic data replied by the intelligent equipment), stops sending the data, and returns a message that the intelligent equipment is successfully connected with the router.
And S4, after the password is obtained according to the analysis result, the distribution network characteristic data is sent to the user equipment through the router.
And the distribution network characteristic data is used for informing the user equipment that the distribution network is successful.
Specifically, after obtaining the password according to the analysis result, sending the distribution network feature data to the user equipment through the router includes:
after obtaining the password according to the analysis result, mdns (start multicast DNS) and register the local network service. After receiving a request for inquiring local network service sent by user equipment, sending distribution network characteristic data to the user equipment, wherein the distribution network characteristic data is in a json format and comprises the following steps: mac address, product type number (pid), and device identity (deviceid). Specifically, the local network service may be a "snink" _ tcp.local "service, which is used for home appliance discovery based on short-range wireless network communication in a region.
When the user equipment starts to send a broadcast or multicast data frame, the multicast DNS (mdns) is started, and a request for inquiring the local network service is sent out at a specified period. After obtaining the ssid and the password, the intelligent device connects with the router by using the ssid and the password, starts mdns after the router is successfully connected, and registers the local network service. After receiving the request for inquiring the local network service, the intelligent device replies distribution network characteristic data (in json format, the data comprises mac address, product type number (pid) and deviceid) to the user equipment through the wireless network of the router.
Further, from the beginning of monitoring the broadcast of the router until a time threshold is exceeded, if the ssid and the password are not successfully acquired, the wireless communication module of the intelligent device is switched from the Sniffer mode to the AP mode. And receiving the ssid and the password sent by the user equipment in the AP mode. For example: as shown in the schematic view of figure 3,
when the intelligent device obtains the ssid and the PassWord (PassWord) by broadcasting or multicasting for more than 45 seconds, if the time is not successful, the intelligent device closes the sniffer mode of the wireless communication module and enters the ap mode.
The tcp listening service (port number: 62210) is started on the wireless communication module.
A user equipment, such as a smart phone, connects to the ap mode wireless communication module, and sends a json string containing an ssid and a password to the wireless communication module (for example, the json string may be specifically encoded as { "ssid": XXXX "," pwd ": XXXX").
The wireless communication module receives and parses the transmitted json string.
After obtaining the ssid and the password, the wireless communication module replies a json string containing the uuid (Unique Identifier of the ue, or called Unique Identifier of the ue), the product type number (pid), and the address of mac to the mobile phone (for example, the json string herein may be specifically encoded as { "uuid": XXXX "," product type number (pid) ": XXXX", "mac": XXXX ").
The embodiment of the invention provides a network distribution method, which can be specifically executed by user equipment and comprises the following steps:
and the user equipment sends the data packet to the intelligent equipment through the router. And receiving the distribution network characteristic data sent by the intelligent equipment through the router, and judging that the intelligent equipment successfully distributes the network after receiving the distribution network characteristic data.
Wherein the data packet includes a multicast packet and a broadcast packet sent by the user equipment to the router, the data packet includes an address tag pointing to the user equipment, the data packet broadcasts a service set identification (ssid) signal, and the data packet is broadcast on a channel by the router. And the intelligent equipment accesses a channel according to the acquired ssid and acquires the password of the router and then sends the distribution network characteristic data.
In a traditional network distribution scheme of the intelligent device, how to enable the intelligent device to obtain an SSID and a password of a router is a problem that the intelligent device needs to solve in a network distribution process, however, due to the consideration of cost control, many intelligent devices are not provided with input and output devices such as a touch screen. Therefore, it is usually necessary to change the smart device itself to the AP mode, connect the mobile phone to the smart device in the AP mode, notify the SSID of the smart device by the mobile phone, and then convert the smart device to the normal mode to connect the router. The switching from the AP mode to the normal mode needs to be restarted, and the time consumption is long;
in this embodiment, the smart device monitors the broadcast of the router and obtains a service set identifier (ssid) signal; after acquiring a specified number of data packets from the ssid signal, accessing a current channel according to the acquired ssid signal; and analyzing the data packet received through the current access channel to obtain a password, accessing to a router, and sending distribution network characteristic data to the user equipment through the router to inform the user equipment of successful distribution network. Therefore, in the process of connecting the router, the conversion process of the communication mode is omitted, the wireless communication module is prevented from being restarted, the consumed time of the distribution network is saved, and the problem that the connection is judged to be the failure of the distribution network due to overtime is solved. Therefore, the operation burden of the after-sale service system is reduced, and particularly the labor cost of after-sale service personnel is reduced.
An embodiment of the present invention further provides a distribution network system, as shown in fig. 1a and fig. 1b, in a coverage area of a wireless signal of a router, including:
