For the monitor terminal of net, making way for the user of public network, actively it is conducted interviews but be not a nothing the matter.
Such as when former typically monitors network, the private network of structure includes NVR equipment and some IPC equipment；This
A little IPC equipment receive the control and management of NVR equipment, and thereon the backward NVR equipment of electricity is registered；NVR equipment has UPnP work(
Can, but IPC does not but possess UPnP functions.When public network user needs actively to access these IPC, such as carry out as in background technology
Signing in of being previously mentioned carry out on its interface configuration parameter when changing, will be helpless.
The characteristics of inventor makes full use of the current monitoring network：NVR has UPnP functions；User needs what is accessed not have
The IPC for having UPnP functions is required to be connect to NVR registrations and is controlled and manages before the method solution easy-to-use to design a set of simplicity
The problem that text is mentioned is accessed the active of IPC solving public network user.
Following examples are illustrated by taking previously mentioned NVR and IPC as an example, but it is understood that can not be in this, as
Limitation of the invention.
With reference to Fig. 2, the embodiment of the present invention is described in detail.
S21, NVR to NAT device sends the port mapping that UPnP controls message request itself, the port information after the mapping
Public network user will be supplied to make it log in the NVR.
NVR is opened after UPnP, obtains a private network IP address from Dynamic Host Configuration Protocol server first, is then sent to NAT router
UPnP controls message request carries out port mapping.
S22, NAT device are received after the request of NVR, reply 200OK after mapping success is carried out to port therein and is given
NVR, represents and successfully 25118 ports are successfully mapped to into NVR.Please join an example of the reply message of Fig. 4.
NAT router successfully carries out port mapping to NVR.Now the user in public network can manually be informed this NVR's
Public network IP and port, then just can directly log in this NVR.One of the UPnP control message structures that NVR sends out to NAT router
Example please join Fig. 3.In the control message, NVR requires that NAT device is mapped to the port of itself for 25118.
The public network address for assuming NAT router is 222.100.10.1, then public network user is input in browser
222.100.10.1:25118 can just log in NVR.
The backward NVR of the upper electricity of S23, IPC is registered.
Not supporting on the IPC of UPnP in same private network after electricity, from Dynamic Host Configuration Protocol server IP address or static configuration is obtained
Registered to NVR after IP address；IPC can add the NVR with ONVIF agreements, and other modes are also not excluded for certainly.
S24, NVR receive the registration message of IPC.
NVR is received after the registration message of IPC, can know correspondence IPC's by ARP message or directly by registration message
MAC Address.In order to distinguish the information of each IPC well, NVR can be locally generated title, the IP address of a storage IPC
With the IPC tables of MAC Address corresponding relation.
It should be noted that the follow-up certification to IPC is carried out in the way of MAC Address binding.This is because when the private of IPC
After the change of net IP address situations such as (such as IPC restart or Dynamic Host Configuration Protocol server is restarted), NVR refreshes IPC according to MAC Address immediately
Table, is so avoided that and cause list item to refresh failure when the private net address for reacquiring conflicts with the private net address before other IPC
The problems such as risk.
Table 1 is an example of the IPC tables that NVR is locally preserved：
| Sequence number | IPC encodes (title) | MAC Address | Private network IP address | Public network IP address and port |
| 1 | HIC2421E | 48ea6306350e | 192.168.1.3 | / |
| 2 | HIC3401S | 48ea6306860e | 192.168.1.4 | / |
| …. | …. | …. | …. | …. |
Table 1
Have recorded two information for being registered to the IPC on NVR in the example of table 1, including the title of IPC, MAC Address,
Private network IP address information.
S25, NVR send the port mapping that improved UPnP control messages ask IPC to NAT device.
NVR constructs new UPnP control messages, is then sent to the port that NAT router request is registered in the IPC on NVR
Mapping.In one example, the new UPnP control messages carry the port of the private network IP address, MAC Address and mapping of IPC.
In fact, the port information of mapping can not be carried, because NAT device completely can be with oneself on one's own initiative by one's own port
Resource allocation is to IPC.Also, MAC Address can not also be carried.And the private network IP address of IPC needs to carry in the control message
In, so that forming the map information comprising the IPC private network IP address and port to be asked on NAT device, such user exists
When public network accesses the IPC, NAT device can just be addressed to the IPC.According to the example of table 1, two IPC have been registered on NVR, institute
With the information that NVR carries the two IPC in the new UPnP control messages of construction, an example of Fig. 5 control messages please be join
Son.
S26, NAT device parse the new UPnP control messages, need the port of mapping to be reflected one by one each IPC
Penetrate.
NAT router can be recognized correctly when receiving new UPnP control messages, and mapping is needed to each IPC in the message
Port mapped one by one.After mapping success, NAT router replys 200OK to NVR, represents successfully by the port of IPC
Mapped.Please join an example for replying message of the NAT router shown in Fig. 6.The IPC of entitled HIC2421E successfully reflects
Port is penetrated for 25119；The IPC success mapped ports of entitled HIC3401S are 25120.
S27, NVR receive the port information of the IPC after NAT device mapping, and are supplied to user to make it port information
IPC can be accessed.
NVR is received after the port information of the IPC after mapping, can pass through the use that message is directly sent it in public network
Family.User in public network is received after port information, just can be with conjunction with the public network address (identical with the public network address of NVR) of IPC
Directly access the IPC in private network.If NVR is not aware which user needs to access IPC or needs to access the use of IPC
Family is a lot, and port is notified that the method for each user seems comparatively laborious by this.
So, here using another kind to NVR, for user operation all very easily methods：NVR is being received
After the port information of the IPC after NAT device mapping, the button of correspondence IPC titles is generated in the WEB interface of itself, work as user
When clicking on, the URL comprising the IPC ports can be automatically generated.Please join Fig. 7, on the interface of NVR, have one it is entitled
The button of the IPC of HIC2421E, when user clicks on, in the browser of user, will generate " http://
222.100.10.1:25119 " URL.So user just can directly pass through NAT router and (IPC be preserved on NAT router
Map information：25119 corresponding private network IP address 192.168.1.3) it is addressed to corresponding IPC and conducts interviews.Here IP
Address 222.100.10.1 is the public network IP address of NAT router, corresponds to after the private network IP address mapping for being also equipment in private network
Public network IP address, 25119 be HIC2421E mapping after port.
NVR can be stored in the IPC port informations after mapping in the corresponding list item of local IPC tables, please join table 2；Then
The corresponding port informations of each IPC according to recording in the IPC tables refresh the button of correspondence IPC in WEB interface.These buttons can
Just to produce after IPC is registered on NVR, after the port information for obtaining mapping the clicking operation of button is associated with
The address port information of IPC.
| Sequence number | IPC encodes (title) | MAC Address | Private network IP address | Public network IP address and port |
| 1 | HIC2421E | 48ea6306350e | 192.168.1.3 | 222.100.10.1:25119 |
| 2 | HIC3401S | 48ea6306860e | 192.168.1.4 | 222.100.10.1:25120 |
| …. | …. | …. | …. | …. |
Table 2
For user, it can be signed in on NVR equipment according to existing mode.If to enter to the IPC under NVR
The change of row relevant configuration, it is only necessary to after NVR is signed in, clicks on the button of correlation IPC on the interface of NVR, just can be automatically
The interface for signing in IPC on, it may be said that extremely facilitate.In addition, the interface of the IPC of user's access is unrelated with NVR, so this behaviour
Work will not take the CPU and internal memory of NVR.
It should be noted that can exchange sequencing between some steps in above-mentioned flow process, such as step S21
And step 23 between.
