The specific network identification code generating function can be set in advance as needed. For example, when a networked device is activated, it generates one or more network identifiers with a specific prefix.

In another embodiment of the present invention, the network identification code of the networked device may be the network identification provided by the network service provider ISP according to the network identification sent by the user after receiving the ID that meets the uniqueness condition transmitted by the user. A verification key is generated by a corresponding relationship between the code and a preset setting, and the network identification attribute and the verification key attribute of the connected device are set according to the network identification code and the generated verification key.

For example, the user can set the network identification code of the connected device through a computer, a mobile phone, and other devices and enter the value of the network identification code through the service interface of the ISP of the network service provider used. The ISP can determine whether the value of the network identification code entered by the user meets the conditions, for example, determine whether the network identification code entered by the user is unique.

Step S210: The search module 201 searches for a service setting identifier ID broadcasted by a networked device, and the pre-shared key verification key corresponding to the network identifier set in the networked device is identified by the network identifier Generated with the corresponding correspondence.

In this embodiment, the network identification code broadcast by the networked device may be dynamically generated by the networked device at startup.

In this embodiment, the verification key corresponding to the network identification code set in the networked device is generated by the network identification code and a preset correspondence relationship, for example, the preset correspondence relationship is a function Key (ID).

In step S211, the first calculation step 202 calculates a verification key corresponding to the network identification code according to the correspondence between the network identification code and the connected peripheral device, wherein the connected peripheral device Correspondence relationships stored in the same correspondence relationships exist in the preset correspondence relationships.

The correspondence relationship stored in the network-connected peripheral device has the same correspondence relationship in the preset correspondence relationship. Therefore, for any network identification code, the connected peripheral device can generate the same authentication key as the connected device, and then the network identification code and the authentication key can be used to establish a connection with the connected device.

In another embodiment of the present invention, the network peripheral method may include the following steps: The judging module 206 judges whether the network identification code satisfies a preset condition; if the network identification code satisfies a preset condition, the triggering module 207 triggers the first computing module 202 according to the network identification code and The correspondence relationship stored in the networked peripheral device calculates a verification key corresponding to the network identification code.

In this embodiment, when a network identification code is searched, a judgment is performed first, and then a verification key calculation is performed. Calculate only when the network identifier meets the conditions to avoid invalid calculations. For example, when searching for a network identification code broadcast by the first networked device, first determine whether the prefix of the network identification code is a preset character, and if so, perform calculation of a verification key.

Step S212: The sending module 203 sends a connection request to the networked device according to the network identification code and the verification key corresponding to the network identification code calculated by the networked peripheral device, so that the networked device After the networked device is connected to the networked peripheral device, the network is accessed via the networked peripheral device.

In this embodiment, after obtaining the network identification code of the connected peripheral device and calculating the authentication key, a connection request is sent to the connected device. Specifically, the request may include the network identification code and the Verify key information.

In step S213, when the first networking module 204 receives the verification pass message returned by the networked device, it confirms that a connection is established with the networked device.

In this embodiment, the network-connected device verifies the network identification code and verification key sent by the network-connected peripheral device. If the verification is successful, a message indicating that the connection is established through verification is returned. After receiving the message, the connected peripheral device can confirm that the connection with the connected device is successfully established.

In another embodiment of the present invention, the corresponding relationships stored in the networked peripheral devices include M corresponding relationships, where M is greater than 1 and M is a positive integer. In the network connection method of the present invention: The first calculation module 202 calculates an i-th verification key corresponding to the ID according to the i-th correspondence between the network identification code and the M correspondences, where i is a positive integer and an initial value Is 1.

The sending module 203 sends a connection request to the first networked device according to the network identification code and the i-th verification key.

If the second computing module 205 receives the verification failure message returned by the first networked device, let i = i + 1, and trigger the first computing module based on the network identifier and the network connection. The i-th correspondence relationship stored in the peripheral device calculates an i-th verification key corresponding to the network identification code.

In this embodiment, if the correspondence relationship stored in the connected peripheral device includes more than one correspondence relationship, when the verification key is calculated according to the network identification code, the verification key may be sequentially calculated and based on the verification key obtained by each calculation. A connection request is sent to the networked device. If a message that the networked device fails to pass the verification is received, calculation is performed according to the next correspondence relationship until a connection is established with the networked device.

Step S214: After establishing a connection with the networked device, the transmission module 210 establishes a connection with the server according to the address of the server, and transmits the device identification codes of the networked peripheral device and the networked device to The server is allowed to perform permission verification.

In step S215, if the permission verification is passed, the communication module 211 performs network communication with the server.

The server is a server to be accessed by the network-connected peripheral device. The address of the server may specifically be a network address of the server.

The device identification codes of the connected peripheral device and the connected device may also be referred to as the device ID of the connected peripheral device and the device ID of the connected device, and may be used to uniquely identify the connected peripheral device and the connected device. And transmitting the identification code of the connected peripheral device and the connected device to a server to enable the server to perform permission verification.

Specifically, the server can store in advance the correspondence between the device identification code of the user and the electronic device and the device identification code of the networked device. When the permission verification is performed, it can be verified whether the electronic device and the networked device are both For a device that a user is entitled to use, if yes, it is determined that the permission verification is passed; if not, it is determined that the permission verification is not passed.

When permission verification is passed, network communication is performed with the server. For example, you can upload and download information.

In another embodiment of the present invention, a corresponding network service operation may also be performed according to the network communication permission allocated by the server according to the device identification code of the connected peripheral device. That is, the server can determine which network services permission rights the network peripheral device has based on the device identification code of the network peripheral device, and assign the network service permission rights to the network peripheral device. Corresponding network business operations are performed according to the assigned permissions.

In another embodiment of the present invention, the network connection method further includes: if the permission authentication fails, the receiving module 212 receives the ID of the second networked device transmitted by the server, wherein the first The pre-shared key verification key corresponding to the network identification code set in the two networked devices is generated by the network identification code and the preset correspondence relationship.

The fourth networking module 213 establishes a connection with the second networked device according to the correspondence between the network identification code of the second networked device and the saved peripheral device.

In this embodiment, the above-mentioned second networked device may be a networked device that is stored in the server and belongs to the same user as the networked peripheral device.

Because the pre-shared key verification key corresponding to the network identification code set in the second networked device is generated by the network identification code and the preset correspondence relationship, therefore, for the same The network identification code, the same authentication key as that of the second networked device can be generated in the networked peripheral device, and then a connection can be established with the second connected device.

The event notification may be that when the web camera detects object movement or the hour decibel exceeds the preset alert value, the web camera captures the current screen and reports a monitoring event and screenshot to the server.

The event recording when offline can be: when the network camera is not connected to the network, if it detects that the object moves or the decibel exceeds the alert value, you need to save the event video, upload the video to the network after obtaining the network connection The server.

The server corresponding to the network camera can notify the user of the occurrence of the event when receiving the monitoring event notification, and guide the user to browse the real-time image data. The server can also record real-time images into event clips when receiving a monitoring event notification. After the event clip images are generated, an impact analysis is performed to determine the number of faces that can be positively detected in the movie. Into one Step by step, the server can also calculate the number of unique people appearing in the event clip image based on the number of faces that can be detected positively in the movie.

For another example, the connected peripheral device is the scanning device of the POS machine. When the scanning device of the POS machine is connected to the network through the connected device and passes the permission authentication on the corresponding server, the scanning device of the POS machine can be real-time ) To record the items and quantities of the products sold and upload them to the server.

The scanning device of the POS machine can also record the inventory situation of various items in the store's warehouse and upload it to the server.

The scanning device of the POS machine can also record the consumption situation of individual customers by means of member ID and upload it to the server.

The server corresponding to the scanning device of the POS machine can automatically order from the supplier when the inventory of specific products is insufficient after receiving the sold product items and quantities, and the inventory of various items in the store's warehouse, to maintain the stability of the supply of goods .
