Description
Technical field
The present invention relates to video network applied technical field, specifically, relate to a kind of wireless connections collocation method for NVR and IPC.
Background technology
In recent years, along with the fast development of IP network, Video Surveillance Industry had also entered the full networked epoch. Fast universal along with wireless network, IPC(web camera) and NVR(Network Personal Video Recorder) between be connected the connected mode that starts too to occur wireless WIFI. Under wireless connections mode, NVR is equivalent to WAP (AP, AccessPoint), and IPC is equivalent to wireless client device (STA, Station).
The step of setting for fear of wireless network encrypting and authenticating is too loaded down with trivial details, reaches the object of quick access of radio network in Practical Project use procedure, conventionally all adopts WPS(Wi-FiProtectedSetup) mode carries out automatically to code. Standard WPS connects PIN code and the two kinds of modes of PBC of being divided into.
Be limited to the product form of IPC, if adopt the mode of PIN code to carry out WPS connection, need to be connected in the control page of IPC and carried out manual input operation by external devices, cause actual disposition process operation complexity, the equipment relating to be numerous;
If carry out WPS connection by the mode of PBC, need on NVR and IPC, all increase a dedicated button, as the connection flip flop equipment of WPS, increase hardware cost;
WPS connects the impact such as the factor that also can be subject to interference in wireless environment to code, reduces code success rate.
Summary of the invention

(S23) NVR replys and replys the encrypted tunnel radio configuration information that IPC asks;
(S24) IPC sets up encryption connection by the encrypted tunnel radio configuration information and the NVR that receive, carries out transmission of streams of video data.
In order to prevent Joint failure, in described step (S21), if IPC and NVR set up non-encrypted connection failure, IPC again attempts setting up non-encrypted connection with NVR after a setting-up time t1.
And, in the time setting up the number of times of non-encrypted connection failure and reach setting threshold, IPC stop connecting with NVR or IPC after a setting-up time t2 more again trial set up non-encrypted connection with NVR.
Further, in described step (S23), after IPC receives the encrypted tunnel radio configuration information of NVR reply, it is stored in IPC.
In order to improve the efficiency of wireless connections configuration, in described step (S20), IPC connects before non-encrypted passage, verifies as follows:
(S20a) whether to check in IPC the radio configuration information of storage encryption passage, if so, carry out next step, continue to carry out otherwise jump to step (S20);
(S20b) IPC sets up encryption connection by the encrypted tunnel radio configuration information of having stored to NVR request, if successful connection is carried out transmission of streams of video data, otherwise entered next step;
(S20c) repeated execution of steps (S20b) after a setting-up time t3, in the time entering the number of times of step (S20c) and reach setting threshold, jumps to step (S20) and continues to carry out.
Wherein, unless using other all radio configuration information outside the encrypted tunnel radio configuration information of ipc memory storage all as the encrypted tunnel radio configuration information of having stored. In the time that the number of the encrypted tunnel radio configuration information of having stored detecting in described step (S20a) is greater than 1, carry out successively in order described step (S20b) ~ (S20c) by these information sortings and to it, wherein, when the information of attempting connecting for this collating sequence last time, described step (S20c) is replaced by following steps:
(S20c ') repeated execution of steps (S20b) after a setting-up time t3 is attempted the connection of current information, in the time entering the number of times of step (S20c ') and reach setting threshold, jumps to step (S20b) and carries out the connection of next information is attempted.
Connect and the stability of transfer of data in order to improve, in described step (S24), in the time that IPC and NVR successfully set up encryption connection, non-encrypted between IPC and NVR is connected disconnection.
Compared with prior art, the present invention has following beneficial effect:
The present invention sets up two passages separately and realizes the data transmission security of IPC wireless connections in NVR, avoided loaded down with trivial details encrypting and authenticating simultaneously, IPC can be connected with NVR automatic quick, thereby to the stable transfer of video data stream, not only do not need to be equipped with extras, nor need to increase hardware cost, data transmission security and stability are also effectively ensured, and the present invention is skillfully constructed, novel unique, simple in structure, with low cost, easy to use, be with a wide range of applications, be applicable to applying.
