To access NVR by mobile client in the wide area network, the video image of each IPC is checked.But supervised in video as deployment
During control system, since the user of a large amount of average family video monitoring systems is for the basic conception of IP and network and using not
Very clear, when mounted often there are such-and-such problem, user it is expected only to need to plug cable, opening electricity after taking equipment
Source can be used.
Although it can accomplish to be linked into IPC for NVR the and IPC equipment in the video monitoring system of mainstream at present
After egress router, NVR scans for find IPC after the power is turned on, and user only needs to add the management to IPC in man-machine interface
.Even if IPC uses third-party equipment, NVR can also be communicated by ONVIF agreements or proprietary protocol with IPC, modification
Its IP address simultaneously adds the management to IPC.But although the IPC equipment of some producers supports automatic discovery, does not support to change
IP, or also need to restart after IP is changed, have to wait for, lose time in restarting process, influence the usage experience of user.
The content of the invention
The object of the present invention is to provide a kind of network video recorder and its method for automatically accessing IPC, to avoid network

Embodiment
Technical solution of the present invention is described in further details with reference to the accompanying drawings and examples, following embodiments are not formed
Limitation of the invention.
The method that a kind of network video recorder of the present embodiment automatically accesses IPC, applied in video monitoring system
NVR, the video monitoring system of the present embodiment can be received including being linked into the NVR of one outlet router and IPC, IPC at the same time
The broadcast message of NVR, in addition video monitoring system further include video monitoring server, egress router and video monitoring server
It is connected with wide area network, client accesses NVR by mobile client.Since the IPC equipment of some third party manufacturers is provided with static state
IP address, if the static ip address and the NVR that set, not in the same network segment, NVR can not communicate with the IPC,
Need to modify to its IP address for, in the same network segment, but the IPC of some producers may not support to carry out it with NVR
IP address is changed, or needs to restart after changing its IP address, and operation is more complicated, therefore the side that the present embodiment proposes
Method can need not carry out IP address modification to it, it becomes possible to access these IPC and normal use.
A kind of network video recorder of the present embodiment automatically accesses the method flow of IPC as shown in Fig. 2, including step：
Step S1, NVR sends ARP broadcast messages, and receives the response message of each IPC feedbacks, which carries
IP address, subnet mask and the port numbers of IPC oneself.
Address resolution protocol, i.e. ARP (Address Resolution Protocol), are to obtain physics according to IP address
One ICP/IP protocol of address.ARP request comprising target ip address is broadcast to the institute on network by host when sending information
There is host, and receive return message, the physical address of target is determined with this；Receive and return after message by the IP address and physically
Location is stored in the machine arp cache and retains certain time, and next time directly inquires about arp cache to economize on resources when asking.In this reality
Apply in example, NVR is broadcast the message by sending ARP, and inquiry is connected to all IPC under same router.As shown in Figure 1, and NVR
ARP broadcast messages can be received by being equally linked into IPC1, IPC2, IPC3 of egress router, and be responded, and be returned
Response message.In the response message, the IP address, subnet mask and port numbers of IPC oneself is carried, port numbers include letter here
Port numbers used by order communication, can also include Media Stream port numbers.So that in subsequent step, NVR passes through these ports
Number with IPC carry out signalling communication, if including Media Stream port numbers in the lump in the response message, can also directly carry out media
The request of stream.
Step S2, according to the IPC response messages of reception, judge to send the IPC of the response message IP address whether with from
The IP address of body network interface card is in the same network segment, if yes then enter in next step；Otherwise one is added on itself network interface card to be somebody's turn to do with sending
The virtual ip address of the same network segment of IP address of the IPC of response message, and the IPC and an increased virtual ip address are tied to
The network interface card of itself, into next step.
After the response message of IPC is received, NVR gets the IP address and subnet mask of each IPC, can judge it accordingly
IP address whether with the IP address of itself network interface card whether in the same network segment, if in the same network segment, then it represents that can be mutual with the IPC
It is logical, directly carry out the operation of next step.Assuming that in Fig. 1 the IP address of IPC1 and IPC2 be respectively 192.168.1.8 and
192.168.1.9, with the IP address (192.168.1.10) of NVR all in the same network segment, and IPC3 (172.168.1.8) with
The IP address of NVR is not in the same network segment.Then for IPC1 and IPC2, it need not be operated, be directly entered down after judgement
One step.And for IPC3, since its IP address and NVR be not in the same network segment, then need to add on the network interface card of NVR one with
The virtual ip address of the same network segment of IP address of IPC3, and the IP address of IPC3 and the virtual ip address added are tied to certainly
Preserved after the network interface card of body, will not also to be lost after device powers down.
Specifically, according to the network interface card quantity of NVR, there are following two embodiments：
Embodiment one, Single NIC situation, i.e. NVR only have a network interface card.NVR passes through after the response message of IPC3 is received
Judge to learn the IP address of IPC3 and the IP address of itself not in the same network segment, then in the identical network segments of IPC3
(172.168.1.2~171.168.1.254) chooses an IP address, for example 172.168.1.30, NVR are carried out to the IP address
Continuous ping, if ping differences (no response reaches default number), then it is assumed that the IP address can use, this IP address is made
It is added to the network interface card of NVR for virtual IP address, subsequently with the communication of IPC3, is carried out by the virtual ip address.If ping leads to,
Change an IP and continue ping, until finding a suitable virtual IP address, or establish and distributed IP management information tables, carry out idle
IP is inquired about, and searches an IP address being not used as virtual IP address, which is not described herein again.
Embodiment two, more network interface card situations, i.e. NVR have multiple network interface cards.What is different from the first embodiment is that for multiple network interface cards
Situation, since NVR is there are multiple network interface cards such as network interface card 1, network interface card 2, the IP address of network interface card 1 is 192.168.1.10, but network interface card 2
IP address be 172.168.1.10.In this case, received response message is docked, first has to that the response message will be sent
IPC IP address compared with the IP address of each network interface card, network interface card and the IPC have been checked whether in the same network segment, if only
There are the IP address of a network interface card and the IP address of the IPC in the same network segment, then bind the IPC and the network interface card；If multiple nets
The IP address of card and the IP address of the IPC in the same network segment, then according to the IPC of the binding on every piece of network interface card how much, loaded
Equilibrium, selects the minimum network interface cards of binding IP C to bind the IPC.If none of network interface card and the IPC in the same network segment, then select
The minimum network interface cards of binding IP C are selected, IP address or virtual IP address are added on the network interface card to bind the IPC.
Such as：For IPC1 and IPC2, its IP address is with network interface card 1 in the same network segment, IPC1 and IPC2 and NVR
Normal communication can be carried out by network interface card 1, IPC1 and IPC2 are tied to network interface card 1 and communicated；The IP address of IPC3 with
The IP address of network interface card 2 can carry out normal communication in the same network segment, then IPC3 and NVR by network interface card 2, and IPC3 is tied to net
Card 2 is communicated.
But when network interface card 2 is not provided with IP address, or its IP address set is also the 192.168.1.* network segments, similarly
IPC1 and IPC2 and NVR can carry out normal communication by network interface card 1, but the IP address of IPC3 and network interface card 1 is in the same network segment,
At this time need to check the IPC that network interface card 1 and network interface card 2 are bound, select the few network interface card of binding relationship, such as network interface card 2 is come with adding IP
Location or virtual ip address, IPC3, network interface card 2, the IP address of addition or virtual ip address binding are communicated.
It should be noted that if network interface card is not provided with IP address, its IP address and the IP address of IPC3 can be configured
The same network segment, without adding virtual ip address.
Step S3, corresponding IPC is added with mode of unicast.
Intercommunication between IPC and NVR is established by step S2, then can be sent by mode of unicast to IPC and establish matchmaker
The process of body stream connection, generally includes following process：
Pre-configured device authentication information is sent to IPC with mode of unicast, is authenticated.The device authentication that NVR is sent disappears
Breath can use the standard agreement such as ONVIF or PISA, can also use proprietary protocol, using the IP of the IPC of step S1 acquisitions
Location and port numbers are sent.If do not receive authentication OK responses or response failure, then it is assumed that corresponding equipment is not IPC, may
It is PC office computers or other equipment, or the operating right without this IPC, for being bundled with the corresponding device and virtual IP address
Network interface card, deletes the binding relationship of the corresponding device and virtual IP address, directly terminates；If it have received authentication OK responses, then it represents that right
The equipment answered is IPC.
Being configured after the response that the authentication is passed is received to IPC sending devices and obtain information, IPC is responded thereto, so that
The information such as equipment time and its video configuration of IPC are obtained, and the configuration of adaptability is carried out to it, or according to default configuration
Directly it is configured, such as to configure its equipment time synchronous with NVR, configures its resolution ratio, code stream type, frame per second, interframe
Every etc. information, or IPC configures meet demand in itself, then need not can be configured.
It should be noted that during adding corresponding IPC with mode of unicast, for the IPC ability for needing to be authenticated
Pre-configured device authentication information is sent, is authenticated；Then directly it is added for the IPC that need not be authenticated.And such as
The configuration information of IPC known to fruit, then directly can configure it and be added, it is not necessary to sending device by default configuration
Configuration obtains information.
By the above process, NVR successfully with the addition of IPC, and following NVR can ask the various Media Streams of IPC
Summation receives, to carry out follow-up Media Stream analysis or storage etc..
Fig. 3 shows the structure diagram of the present embodiment network video recorder, including equipment discovery module, network configuration
Module, configuration management module.Wherein：
Equipment discovery module is used to send ARP broadcast messages, and receives the response message of each IPC feedbacks, by response message
In IP address, subnet mask and the port numbers of the IPC that include notify to Network conf iotag module and configuration management module；
Network conf iotag module be used for judge transmission the response message IPC IP address whether the IP address with itself network interface card
In the same network segment, do not operate if it is；Otherwise an IP with the IPC of the transmission response message is added on itself network interface card
The virtual ip address of the same network segment in location, and by the IPC with increased virtual ip address be tied to the network interface card of itself；
The IPC that configuration management module is used to find to equipment discovery module adds corresponding IPC with mode of unicast.
Further, if network video recorder has at least two network interface cards, Network conf iotag module is additionally operable to：
The IP address of the IPC of the response message will be sent compared with the IP address of each network interface card, checked whether network interface card
With the IPC in the same network segment, if the IP address of only one network interface card and the IP address of the IPC should in the same network segment, binding
IPC and the network interface card；If the IP address of multiple network interface cards and the IP address of the IPC are in the same network segment, then according on every piece of network interface card
Binding IPC how much, carry out load balancing, select the minimum network interface card of binding IP C to bind the IPC；If none of net
Card in the same network segment, then selects the minimum network interface cards of binding IP C with the IPC, and one is added on the network interface card, and the response disappears with transmission
The IP address of the same network segment of IP address of the IPC of breath, and the IPC and the IP address added are tied to the network interface card.
Or：The IP address of the IPC of the response message will be sent compared with the IP address of each network interface card, checked whether net
Card with the IPC in the same network segment, if the IP address of the IP address of only one network interface card and the IPC in the same network segment, are bound
The IPC and the network interface card；If the IP address of multiple network interface cards and the IP address of the IPC are in the same network segment, then according to every piece of network interface card
On binding IPC how much, carry out load balancing, select the minimum network interface card of binding IP C to bind the IPC；If none of
Network interface card and the IPC then select the minimum network interface cards of binding IP C, one are added on the network interface card with sending the response in the same network segment
The virtual ip address of the same network segment of IP address of the IPC of message, and the IPC and the virtual ip address added are tied to the net
Card.
After network configuration is completed, configuration management module is able to unicast and leads to IPC according to the configuration of Network conf iotag module
Letter, when adding corresponding IPC with mode of unicast, performs following operation：
Sending device authentication information is authenticated, if not receiving authentication OK responses to the IPC for sending the response message
Or response failure, then for being bundled with virtual IP address, delete the binding relationship with virtual IP address；
After the authentication is passed, configured to the IPC sending devices and obtain information, and it is matched somebody with somebody according to the response of the IPC
Put, or directly it is configured according to default configuration.
So as to which NVR is after successfully IPC is added, medium stream request is carried out to IPC with receiving, and receive the media of IPC transmissions
Stream is analyzed or stored.
