Embodiment Construction

[0027] As shown in FIG. 1 , the multi-IP communication system of the present invention includes an embedded device 10 and a monitoring center 20 . The embedded device 10 communicates with the monitoring center 20 through TCP / IP protocol.

[0028] The embedded device 10 is provided with a storage module 11 and a drive module 12 , and of course also includes other modules, such as a processing module, an image acquisition module, a power supply module and the like. There are multiple groups of network parameters stored in the storage module 11 , for example, n groups of network parameters, n greater than 1, used to initialize the TCP / IP protocol stack in the drive module 12 and communicate with the monitoring center 20 . When it is necessary to change the network parameters, it is only necessary to call each group of network parameters in turn, reinitialize the TCP / IP protocol stack of the driver module 12, and try to establish a TCP connection with the monitoring center 20 unti...

Abstract

The invention relates to a multi-IP communication method and system. And the system comprises embedded equipment and monitoring center, where the embedded equipment is stored with multiple groups of network parameters and when requiring to communicate with the monitoring center, calls first group of network parameters to initialize TCP / IP protocol stack and tries to make TCP link with the monitoring center; after succeeding in making the TCP link in the set time, communicates with the monitoring center by TCP / IP protocol; if TCP link is unable to be made in the set time, calls the next group of network parameters, re-initializes the TCP / IP protocol stack and retries to make TCP link with the monitoring center; if the TCP link is unable to be made, continues to call the next group of network parameters until succeeding in making the TCP link. And it can automatically change the network parameters in an extremely short time, make link between the embedded equipment and the monitoring center and assures real-time online of the embedded equipment.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and system for realizing multi-IP communication. Background technique [0002] Existing embedded devices, such as some terminal devices with camera monitoring, only provide a set of network parameters when there is only one network interface. In a monitoring system, there are often tens of thousands of such terminal devices. [0003] Due to the actual situation, for example, telecom, mobile, China Unicom and other communication companies have scattered computer rooms. In order to balance the network load, it is often necessary to change the IP address of the local access network equipment at a specified time point. Therefore, the IP must be changed before the specified time point, or the IP must be changed on site after that time point, otherwise the monitoring center will not be able to access the device when the time point comes and the original IP i...
