Embodiment
Be described in further details technical solution of the present invention below in conjunction with drawings and Examples, following examples do not form limitation of the invention.
A kind of network video recorder of the present embodiment accesses the method for IPC automatically, be applied to the NVR in video monitoring system, the video monitoring system of the present embodiment comprises NVR and IPC being simultaneously linked into an egress router, IPC can receive the broadcast of NVR, in addition video monitoring system also comprises video monitoring server, egress router is connected with wide area network with video monitoring server, and client accesses NVR by mobile client.IPC equipment due to some third party manufacturer is provided with static IP address, if the static ip address arranged and NVR be not in the same network segment, then NVR cannot communicate with this IPC, need to its IP address modify into NVR at the same network segment, but the IPC of some producer may not support to carry out the amendment of IP address to it, or need to restart after revising its IP address, operation more complicated, therefore the method that the present embodiment proposes can not need to carry out the amendment of IP address to it, just can access these IPC and normal use.
A kind of network video recorder of the present embodiment accesses the method flow of IPC as shown in Figure 2 automatically, comprises step:
Step S1, NVR send ARP broadcast, and receive the response message that each IPC feeds back, and this response message carries the IP address of IPC oneself, subnet mask and port numbers.
Address resolution protocol, i.e. ARP (Address Resolution Protocol) are ICP/IP protocol according to IP address acquisition physical address.When main frame sends information, the ARP comprising target ip address is asked the All hosts be broadcast on network, and receive return messages, determine the physical address of target with this; After receiving return messages by this IP address and physical address stored in retaining certain hour in the machine arp cache, directly inquire about arp cache to economize on resources during request next time.In the present embodiment, NVR is by sending ARP broadcast, and inquiry is connected to all IPC under same router.As shown in Figure 1, IPC1, IPC2, IPC3 of being linked into egress router same with NVR can both receive this ARP broadcast, and responds, and returns response message.In the response message, carry the IP address of IPC oneself, subnet mask and port numbers, port numbers comprises the port numbers that signalling communication adopts here, also can comprise Media Stream port numbers.So that in subsequent step, NVR carries out signalling communication by these port numbers and IPC, if include Media Stream port numbers in the lump in the response message, then also directly can carry out the request of Media Stream.
Step S2, according to the IPC response message received, the IP address judging the IPC of this response message of transmission whether with the IP address of self network interface card at the same network segment, if yes then enter next step; Otherwise add on self network interface card one with the virtual ip address of the same network segment in IP address of IPC sending this response message, and by the network interface card that this IPC and the virtual ip address that increases are tied to self, enter next step.
After receiving the response message of IPC, NVR gets IP address and the subnet mask of each IPC, can judge accordingly its IP address whether with the IP address of self network interface card whether at the same network segment, if at the same network segment, then representing can intercommunication with this IPC, directly carries out next step operation.Suppose that the IP address of IPC1 and IPC2 in Fig. 1 is respectively 192.168.1.8 and 192.168.1.9, with the IP address (192.168.1.10) of NVR all at the same network segment, and the IP address of IPC3 (172.168.1.8) and NVR is not at the same network segment.Then for IPC1 and IPC2, do not need to operate after judgement, directly enter next step.And for IPC3, because its IP address and NVR be not at 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 in IP address of IPC3, and preserve, also can not lose after device powers down after the IP address of IPC3 and the virtual ip address added are tied to the network interface card of self.
Particularly, according to the network interface card quantity of NVR, there are following two embodiments:
Embodiment one, Single NIC situation, namely NVR only has a network interface card.NVR is after receiving the response message of IPC3, by judging to learn that the IP address of IPC3 and the IP address of self be not at the same network segment, then in the network segment that IPC3 is identical, (172.168.1.2 ~ 171.168.1.254) chooses an IP address, such as 172.168.1.30, NVR carries out continuous print ping to this IP address, if ping difference (reaching default number of times without response), then think that this IP address can be used, this IP address is added to the network interface card of NVR as virtual IP address, the follow-up communication with IPC3, is all undertaken by this virtual ip address.If ping leads to, then change IP and continue ping, until find a suitable virtual IP address, or set up distributing IP management information table, carry out idle IP inquiry, search one not by the IP address that uses as virtual IP address, repeat no more here.
Embodiment two, many network interface cards situation, namely NVR has multiple network interface card.With embodiment one unlike, for the situation of multiple network interface card, because NVR exists multiple network interface card such as network interface card 1, network interface card 2, the IP address of network interface card 1 is 192.168.1.10, but the IP address of network interface card 2 is 172.168.1.10.In this case, to the response message received, first the IP address of IPC and the IP address of each network interface card that send this response message to be compared, look into and see if there is network interface card and this IPC at the same network segment, if only have the IP address of the IP address of a network interface card and this IPC at the same network segment, then bind this IPC and this network interface card; If have the IP address of the IP address of multiple network interface card and this IPC at the same network segment, then how many according to the IPC of the binding on every block network interface card, carry out load balancing, select the minimum network interface card of binding IP C to bind this IPC.If neither one network interface card and this IPC are at the same network segment, then select the minimum network interface card of binding IP C, this network interface card adds IP address or virtual IP address to bind this IPC.
Such as: for IPC1 and IPC2, its IP address and network interface card 1 at the same network segment, IPC1 and IPC2 and NVR can carry out proper communication by network interface card 1, IPC1 with IPC2 is tied to network interface card 1 and carries out communicating; The IP address of IPC3 and the IP address of network interface card 2 are at the same network segment, then IPC3 and NVR can carry out proper communication by network interface card 2, IPC3 are tied to network interface card 2 and carry out communicating.
But when network interface card 2 does not arrange IP address, or its IP address arranged is when being also the 192.168.1.* network segment, in like manner IPC1 and IPC2 and NVR can carry out proper communication by network interface card 1, but the IP address of IPC3 and network interface card 1 is not at the same network segment, at this time need the IPC checking that network interface card 1 and network interface card 2 are bound, select the network interface card that binding relationship is few, such as network interface card 2 adds IP address or virtual ip address, IPC3, network interface card 2, the IP address of adding or virtual ip address binding is communicated.
It should be noted that, if network interface card does not arrange IP address, then can configure the same network segment in IP address of its IP address and IPC3, and do not need to add virtual ip address.
Step S3, add corresponding IPC with mode of unicast.
Establish the intercommunication between IPC and NVR by step S2, then can send by mode of unicast the process set up Media Stream and connect to IPC, generally include following process:
Send pre-configured device authentication information with mode of unicast to IPC, carry out authentication.The device authentication message that NVR sends can adopt the standard agreements such as ONVIF or PISA, also can adopt proprietary protocol, and IP address and the port numbers of the IPC adopting step S1 to obtain send.If do not receive authentication OK response or respond unsuccessfully, then think that corresponding equipment is not IPC, may be PC office computer or other equipment, or there is no the operating right of this IPC, for the network interface card having bound this corresponding device and virtual IP address, delete the binding relationship of this corresponding device and virtual IP address, directly terminate; If have received authentication OK response, then represent that corresponding equipment is IPC.
To IPC transmitting apparatus configuration obtaining information after receiving the response that authentication passes through, IPC responds it, thus the information such as the equipment time of acquisition IPC and video configuration thereof, and adaptive configuration is carried out to it, or directly it is configured according to the configuration preset, such as configure its equipment time synchronous with NVR, configure the information such as its resolution, code stream type, frame per second, frame period, or the configuration of IPC own satisfies the demands, then can be configured.
It should be noted that, adding with mode of unicast in the process of corresponding IPC, for needing the IPC carrying out authentication just to send pre-configured device authentication information, carrying out authentication; Then directly add for not needing the IPC carrying out authentication.And if the configuration information of known IPC, then can by preset configuration directly it be configured and add, do not need transmitting apparatus configure obtaining information.
By said process, NVR successfully with the addition of IPC, and following NVR just can ask the various Media Streams of IPC and receive, to carry out follow-up Media Stream analysis or storage etc.
Fig. 3 shows the structural representation of the present embodiment network video recorder, comprises device discovery module, Network conf iotag. module, Configuration Manager.Wherein:
