Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.
Rear end equipment in the embodiment of the present invention may include controller, interchanger or the server with store function
Deng.Below by taking rear end equipment is NVR as an example, the several ways of rear end equipment access IPC in the prior art are introduced:
First way:It is that NVR and IPC specifies IP address first, then on NVR by way of configuring, by IPC's
The information such as IP address and the user name of login user, password are added in the digital channel configuration item of the NVR of correspondence mappings, NVR
It based on the access protocol between IPC, is logged in by verification, realizes access IPC.
As it can be seen that first way is by specifying IP address, the mode being then reconfigured to realize that NVR accesses IPC.This side
Formula needs user's manual configuration, user experience poor.Furthermore IPC in the market itself, can only substantially without user interface
The IP address that IPC is known or changed by auxiliary tool, this requires users to have the knowledge background of this respect, i.e., to user
It is more demanding, and manual configuration carry out operation be also more troublesome.
The second way:NVR sends ARP broadcast messages to one or more IPC, and the response for receiving each IPC feedbacks disappears
Breath, the response message carry the IP address, subnet mask and port numbers of IPC itself.The sound that NVR is fed back according to the IPC of reception
Message is answered, the negotiation that IP address is carried out to IPC is changed, and after determining IP address, corresponding IPC is accessed with mode of unicast.
The third mode:It is similar with the second way, it can only pass through dynamic host configuration protocol between NVR and IPC
The mode of (Dynamic Host Configuration Protocol, DHCP) network negotiates the scheme of access, no longer superfluous here
It states.
Above-mentioned existing second and third kind of mode:In small application scene, such as when only separate unit NVR, access is more manual
Configuration is facilitated.But in relatively large application scenarios, for example there is when more NVR, and it is impracticable.This is because there are more
When NVR, the situation of IPC and NVR correspondence confusions are will appear in broadcast negotiation, i.e. IPC does not know which corresponding NVR, and
Which platform IPC that NVR does not know access yet is.It is even more that can not access for specified NVR and specified IPC, at this time also
It is to need manual modification IP address, is more troublesome.Moreover, because PC and NVR correspondences are chaotic so that NVR can not know IPC
Username and password correspondence, in order to enable NVR accesses IPC, IPC can use, it will usually be arranged to more IPC
Unified default authentication user name password, to which there are security risks.
In consideration of it, an embodiment of the present invention provides a kind of methods of NVR connections IPC, wherein NVR can periodically be sent out
The first request message is sent, to obtain the MAC Address for the not connected IPC for being located at same multicast network with NVR.Again by acquisition
MAC Address is compared with MAC Address in default mapping relations, if there is the MAC Address phase with acquisition in default mapping relations
The first same MAC Address, then it represents that there is also the IPC not connect with NVR.So NVR can by with the first MAC Address pair
The digital channel answered is established with not connected IPC and is connected.Without being configured to IPC, do not need manual modification IPC's yet
IP address, the used time is less, NVR can be made to access IPC quickly.
Technical solution provided in an embodiment of the present invention is introduced with reference to the accompanying drawings of the specification.
Fig. 1 is referred to, the embodiment of the present invention provides a kind of connection method, for connecting rear end equipment and web camera
IPC, this method can be executed by rear end equipment, and the flow of this method is described as follows:
S101:Rear end equipment periodically sends the first request message, and the first request message is for obtaining not connected IPC
MAC Address, wherein not connected IPC is located at same multicast network with rear end equipment;
S102:The first response message that the not connected IPC of rear end equipment reception is fed back according to the first request message, first
Response message carries MAC Address;
S103:Rear end equipment judges whether MAC Address and the first MAC Address in default mapping relations are identical, wherein pre-
If mapping relations are used to indicate the correspondence of the data channel of rear end equipment and the MAC Address for each IPC to be accessed;
S104:If identical, rear end equipment is established by digital channel corresponding with the first MAC Address and not connected IPC
Connection.
One rear end equipment can access more IPC, accordingly, provide another rear end equipment connection IPC's again below
Method, this method can be executed by IPC, and the flow of this method is described as follows:
S201:IPC receives the first request message that rear end equipment is sent, wherein the first request message is for obtaining IPC's
MAC Address, IPC and rear end equipment are located at same multicast network;
S202:According to the first request message, end equipment feeds back the first response message to IPC backward, and the first response message carries
The MAC Address of IPC, wherein the data channel of rear end equipment is corresponding with the MAC Address for each IPC to be accessed, MAC Address with
First digital channel corresponds to, and IPC is connect by the first digital channel with rear end equipment.
By taking rear end equipment is NVR as an example, the major function of NVR is and to provide video by IPC transmission digital video code streams
The management such as storage, preview and the playback of code stream.In general, forming a monitoring node, multiple monitoring by the IPC of NVR and its access
Node forms distributed network, to realize Distributed Multi-tier Structure network environment.
One NVR may include multiple digital channels, and the digital channel of NVR can be connect by NVR with IPC, realize that NVR connects
Enter IPC.One digital channel can connect an IPC.The video image of IPC acquisitions can be converted to compressed video bit stream transmission
The video code flow of IPC transmission is received, storage, preview, playback and the forwarding of video code flow are provided to NVR, NVR.
In the prior art or by above-mentioned first way, or by the connection of second way realization NVR and IPC, but
Be the IP address for being required for manual modification IPC, be more troublesome, in addition encounter can not manual modification IPC when, just do not realize NVR
With the connection of IPC.
In consideration of it, the NVR in the embodiment of the present invention can will need the digital channel of the MAC Address and NVR that access IPC to build
Vertical mapping relations, and preserve the verification information for logging in each IPC.Specified multicast network can be added in NVR, same each IPC
The multicast network can also be added.Each IPC can access DHCP networks before the multicast network is added, automatic to obtain respectively
IP address.If also having the IPC not connect with NVR, i.e. digital channel also available free NVR in the multicast network.Due to not
The IPC of connection may more than one, so NVR can periodically send the first request message at this time, with to not connected IPC
The MAC Address of the not connected IPC of acquisition request.Even if not connected IPC more than one, can also obtain all not connected
The MAC Address of IPC.Sending the duration in the period of the first request message can preset, and can be 10 seconds, can also be 20
Second or other possible values, are not restricted here.
If there is no idle digital channels in the digital channel of NVR, that is, in the multicast network NVR with positioned at should
Each IPC in multicast network has connected, at this point, NVR can stop sending the first request message.So far, NVR can also be true
The corresponding MAC Address for being set to the digital channel configuration of NVR has all matched, at this point, NVR can exit multicast network.
Each not connected IPC can receive the first request message of NVR transmissions, if first in not connected IPC
IPC receives the first request message of NVR transmissions, then can feed back the first response message according to the first request message, wherein the
One response message carries the MAC Address of the first IPC.NVR receives the first response message of the first IPC feedbacks, can be from the
The MAC Address of the first IPC of carrying is obtained in one response message.NVR may determine that the MAC Address of the first IPC and default mapping
Whether the first MAC Address in relationship identical, wherein default mapping relations are used to indicate the data channel of NVR and to be accessed
The correspondence of the MAC Address of each IPC, the data channel of NVR and the MAC Address for each IPC to be accessed can be one by one
Corresponding, can also be a data channel of NVR can correspond to the MAC Address of multiple IPC.
When the MAC Address of the data channel of NVR and each IPC to be accessed can be corresponded, the first number of NVR
Word channel is corresponding with the first MAC Address, can be with if NVR determines that the MAC Address of the first IPC is identical as the first MAC Address
Think that the first IPC should be connect with the first digital channel of NVR.If the MAC Address and the first MAC Address of the first IPC are not
It is identical, then can consider that the first IPC is not the IPC being connect with this NVR, wherein the first MAC Address can be default mapping
Any one MAC Address in relationship.
When a data channel of NVR corresponds to the MAC Address of multiple IPC, such as the first data channel of NVR and four
MAC Address corresponds to, and this four MAC Address are the MAC Address of the first IPC, the 2nd IPC, the 3rd IPC and the 4th IPC respectively.
In same multicast network, if the first IPC, the 2nd IPC, the 3rd IPC and the 4th IPC are in not-connected status, work as NVR
After sending the first request message, the first IPC, the 2nd IPC, the 3rd IPC and the 4th IPC with respectively feeding back the MAC of itself to NVR
Location.And NVR receive the first IPC, the 2nd IPC, the 3rd IPC and the 4th IPC feedback MAC Address at the time of may it is identical,
It may be different.If NVR receives the MAC Address of the first IPC, the 2nd IPC, the 3rd IPC and the 4th IPC feedbacks simultaneously,
NVR can be established with any one IPC therein and be connected.If NVR receives the first IPC, the 2nd IPC, the 3rd IPC and the 4th
Have successively at the time of the MAC Address of IPC feedbacks, then NVR can be connect with the IPC of earliest feedback MAC Address.
Since each IPC can be by MAC Address unique mark, then the NVR each IPC to be accessed can also pass through
MAC Address unique mark.If the MAC Address of the first IPC is identical as the first MAC Address, NVR can be by with the first MAC
Corresponding first digital channel in location is established with not connected IPC and is connected.And first response message in addition to carrying the first IPC
Except MAC Address, the IP address of the first IPC can also be carried.The IP address of first IPC is to be added in DHCP networks to obtain automatically
, therefore manual setting is not needed, NVR can know the IP address of the first IPC by the first response message, and then pass through IP
The digital channel of address and NVR carry out pairing connection.
When NVR establishes connection by the first digital channel corresponding with the first MAC Address with not connected IPC, NVR is first
It can determine the item types that NVR is used, further according to determining item types, determine to be used between not connected IPC
Access protocol, the IPC not accessed according still further to determining access protocol request access.
In the embodiment of the present invention, item types can serve to indicate that the scope of business that NVR is used.Such as item types can be with
Including public security security protection and enterprise's security protection or other possible security protections.The access protocol that different item types use is also
It is different.For example, if item types are public security security protections, access protocol can be 28181 agreement of standard GB/T, if item
Mesh type is enterprise's security protection, then access protocol can be professional standard ONVIF agreements.Or sometimes NVR can be with regard to user
Oneself defines access protocol, it is also assumed that being privately owned access protocol.
In the prior art, NVR is specified informs that IPC connected to it this accesses to be used are assisted using a kind of access protocol
View, access way are single.NVR in the embodiment of the present invention can support a variety of access protocols, different item types to correspond to phase
Same or different access protocol.NVR determines the access to be used between not connected IPC according to determining item types
When agreement, the first access protocol corresponding with type of identifying project can be selected from least one access protocol of storage.It can
In the embodiment of energy, the item types of NVR can be set in advance in NVR, and the access protocol that NVR is supported can with item types
To establish mapping relations, it is stored in NVR.As NVR it needs to be determined that when the first access protocol, the item types of NVR can be obtained,
And determine the first access protocol according to mapping relations.
If NVR will be communicated with IPC, NVR if, needs to inform selected first access protocols of IPC, so as to IPC
The first access protocol is selected, is communicated with NVR based on the first access protocol.In possible embodiment, NVR can be to not connecting
The IPC connect sends the second request message, and the second request message can carry the mark of the first access protocol, not connected for informing
IPC use the first access protocol connect.
By taking not connected IPC is the first IPC as an example, the first IPC receives the second request message that NVR is sent, and can obtain
Second request message, which is used to indicate NVR, will use the first access protocol, such as the second request message to carry the first access protocol
Mark, to which the first IPC determines that access protocol to be used is the first access protocol according to the mark of the first access protocol.First
IPC can determine whether to agree to use the first access protocol according to the second request message, and send the second response message to NVR,
Wherein, the second response message can serve to indicate that whether the first IPC agrees to use the first access protocol, to inform NVR, first
Whether IPC agrees to use the first access protocol.
NVR receives the second response message that the first IPC is sent, and the second response message is parsed, to whether know the first IPC
Agree to use the first access protocol.If the second response message indicates that the first IPC agrees to use the first access protocol, NVR
The message that connection is established in request can be sent to the first IPC, the first IPC is accessed using the first access protocol for asking.First
IPC receives the message that connection is established in the request that NVR is sent, can by the first access protocol, according to the IP address of the first IPC with
The first data channel in NVR establishes connection.When establishing connection, NVR can be carried out according to the log-on message of the first IPC of preservation
Verification, after being verified, NVR and the first IPC are established and are connected.
If the second response message indicates that the first IPC is disagreed using the first access protocol, NVR can be again to the
One IPC sends the second request message, wherein second request message can carry the mark of the second access protocol, to inform the
One IPC is connected using the second access protocol.At this point, the second access protocol that the first IPC can be carried according to the second request message
Mark, to according to the mark of the second access protocol determine that access protocol to be used is the second access protocol.
NVR can receive the second response message of the first IPC transmissions, the second response message be parsed, to know the first IPC
Whether agreement uses the second access protocol.If the second response message indicates that the first IPC agrees to use the second access protocol,
NVR can send the message that connection is established in request to the first IPC.If the second response message indicates that the first IPC disagrees use
Second access protocol, then NVR can send the second request message to the first IPC again, wherein second request message can be with
The mark for carrying third access protocol, to inform that the first IPC is connected using third access protocol.Or the first IPC of request is informed
Which kind of access protocol used.As it can be seen that the NVR in the embodiment of the present invention can be negotiated to be connect using which kind of before connecting IPC with IPC
Enter agreement, access way is more flexible.
In conclusion the NVR in the embodiment of the present invention realizes the MAC of configuration its digital channel and each IPC to be accessed
Which IPC addresses has also not connected by MAC Address determination in the pre-connection.If NVR has determined which IPC is not connected,
And not connected IPC can feed back the first response message to NVR, the first response message further includes IP in addition to including MAC Address
Location, the IP address so as to be fed back by IPC establish connection.During this, does not need manual setting or change the IP of IPC
Address, it is more convenient, NVR can be made to access each IPC quickly.
In addition, even if in relatively large application scenarios, for example there is when more NVR, provide through the embodiment of the present invention
The method that NVR accesses IPC may be implemented every NVR determination and be connect with which platform IPC, i.e., the correspondence of clear NVR and IPC,
