S401: all video monitoring terminals are to network interconnection apparatus, network interconnection request port mapping, and obtain the IP address;
Because all video monitoring terminals are all only torn the UPNP agreement open, equipment is after being connected to in-house network, equipment can add port mapping to router by the UPNP agreement at first automatically, in this process, the equipment that at first is mapped to 80 ports is promptly as the main equipment in all video monitoring terminals, and the terminal that is registered to other ports is then as slave unit.
S402: all video monitoring terminals are sent the DDNS register requirement to the DDNS server;
May there be multiple devices in in-house network, the user generally will visit any equipment wherein, therefore every equipment all must have unique sign to distinguish, be generally domain name and the user imports in browser, company or unit generally have only a domain name, but equipment is in the increase that does not stop, replacing, if every increase or to change an equipment all be that it distributes new domain name, this is unpractical, and the introducing of DDNS technology just can solve this problem by recycling DDNS so.The user only need know the current domain name of the equipment that he visits, and just can visit this equipment in the in-house network by key in this domain name in browser.
In this step, the mode that terminal obtains DDNS can have multiple, peanut shell, 3322 or well-known DDNS service such as BIND9, but those access waies expend too big, therefore in the present invention, employing is provided with a special-purpose DDNS DDNS server in local area network (LAN), handled by its unified processing from the equipment DDNS, as long as in the agreement of DDNS and the domain name registration of equipment room definition request dynamic.
S403:(3) DDNS server application for registration DDNS, and whether notice video monitoring terminal succeeds in registration;
In case succeed in registration, then slave unit uses when main equipment domain-name information bag is redirected for main equipment.
S404:(4) user side is by internet access video monitoring terminal.
Because, user side can only pass through the domain name access node, therefore user side can be imported the DDNS that needs access node in browser, promptly be connected to 80 ports (80 ports are default ports that domain name connects) of network interconnection apparatus, network interconnection (for example router), because 80 ports are defined as main equipment, then this moment, main equipment can be inquired about the domain name tabulation that is stored in equipment all in the main equipment, what determine that the user will visit is that equipment, if main equipment, just do not need to do redirected, direct and user browser connects, if slave unit, then be redirected to the slave unit of appointment again by main equipment, the slave unit of appointment has just been set up with user's browser and has been connected like this, connect the foundation back and just can use http protocol to communicate, user side comes control appliance by http protocol
In step 401, main equipment is not changeless, after former main equipment rolls off the production line, need compete main equipment again, how knowing that main equipment rolls off the production line can regularly send heartbeat packet to main equipment by slave unit, main equipment is replied after receiving heartbeat packet, if surpassing predefined number of times (for example 3 this), slave unit do not receive that heartbeat replys then think that main equipment rolls off the production line, this moment is 80 original port mapping of deletion earlier, slave unit is promptly competed 80 mapped port again afterwards, and the video monitoring terminal of competing 80 ports once more is promptly as the main equipment in the new mapping.
In system, network interconnection apparatus, network interconnection might be replaced, and all of the port mapping will not exist behind the replacing router, so need provide a kind of mechanism to guarantee can reset automatically after router is changed, the assurance system can also normally move, and can realize by following manner
(1) whether main equipment needs regular check 80 port mapping record to exist and points to self, if there is no then need add map information again, if 80 port mapping pointed to other slave units (for example since 80 port mapping by manual modification, perhaps some other special circumstances), then need stop to reply, so that other equipment go again the read port mapping table to obtain correct master server IP or remove to compete again master server.
(2) whether slave unit regular check self port mapping exists, and does not then solve router and re-registers port mapping if do not exist.
In sum, adopt system and method for the present invention, user terminal can need not to adopt VPN by the Internet, can realize visiting the far-end video monitoring equipment, and can improve access to netwoks efficient; Adopt fault tolerant mechanism, can avoid making the problem that system can not normally move because the network interconnection apparatus, network interconnection replacing causes port mapping not exist; Adopt competition mechanism to determine the port of external reference, and utilize redirection mechanism to realize the accuracy of access means; Can make things convenient for the user largely, and not need higher cost.
More than disclosed only be several preferred embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection range of the present utility model.
