IPC automatic detection and connection method based on ARP protocol and ONVIF standard

Abstract

The invention discloses an IPC automatic detection and connection method based on an ARP protocol and an ONVIF standard. The method is applied in an NVR-IPC network. An ARP monitoring module and an ONVIF detection module are configured in an NVR (Network Video Recorder); the ARP monitoring module monitors the ARP message in the network; when the ARP monitoring module monitors an ARP request message from an ICP, the configuration information of the ICP is obtained from the message; the NVR builds connection with the IPC through AN configuration information and communicates with the IPC; the ONVIF detection module broadcasts in the network periodically; after the unconnected IPC receives the broadcasted message, a connection request is sent to the NVR; the NVR obtains the configuration information of the IPC through the received connection request; the NVR builds connection with the IPC through the configuration information and communicates with the IPC. According to the method provided by the invention, the address resolution protocol and the ONVIF standard are utilized skillfully; the NVR can locally and automatically discover the IPCs connected with the NVR and build communication connection with the IPCs; especially under a condition that the network configuration information of the IPCs are set, the configuration convenience of the NVR-IPC network is greatly improved.

Description

technical field [0001] The invention relates to the field of video network application technology, in particular to an IPC automatic detection connection method based on the ARP protocol and the ONVIF standard. Background technique [0002] NVR is the abbreviation of Network Video Recorder (Network Video Recorder). The main function of NVR is to receive the digital video stream transmitted by IPC (IPCamera network camera) equipment through the network, store and manage it, so as to realize the advantages of distributed architecture brought by networking. [0003] During the use of NVR-IPC networking, there are often cases where the IPC is damaged and needs to be replaced. When the configuration of the replaced IPC is inconsistent with the original IPC configuration or the current network configuration, it will not be able to communicate The NVR needs to communicate with each other. At this time, it needs to be configured manually. However, the steps of manually configuring...

Problems solved by technology

However, in practice, due to various external reasons, some IPCs cannot be directly connected to the new NVR-IPC network after the network settings have been made. As a result, these IPCs cannot be used directly, and cumbersome manual work is required. configuration process
