Method for discovering equipment in local area network based on UDP broadcast

Abstract

The invention discloses a method for discovering equipment in a local area network based on UDP broadcast, which comprises the following steps that: an NVR sends a UDP broadcast message in the local area network, and searches an IPC to be added in the local area network through the sent UDP broadcast message, so that the IPC in the local area network returns IPC equipment information correspondingto the IPC; the NVR receives IPC equipment information returned by the IPC and displays the received IPC equipment information, so that a user can confirm whether to add the IPC corresponding to theIPC equipment information to an equipment management list corresponding to the NVR or not; the NVR receives an addition confirmation instruction triggered by a user, and adds the IPC equipment information to an equipment management list corresponding to the NVR according to the addition confirmation instruction; and the purpose of discovering the IPC equipment to be added in the local area networkby using the UDP broadcast message is achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for discovering devices in a local area network based on UDP broadcast. Background technique [0002] Network Video Recorder (NVR), the most important function is to receive the digital video code stream transmitted by the network camera (IP Camera, IPC) equipment through the network, and store and manage the received digital video code stream, so that Realize the advantages of distributed architecture brought by networking. In actual use, one NVR usually needs to manage multiple IPCs, and each of the managed IPCs needs to be configured one by one. The traditional configuration method is that for NVR, when technicians manually add multiple IPCs for management, they need to manually enter information such as the manufacturer, IP address, port, account, password, etc. corresponding to each IPC. The adding process is cumbersome. Multiple IPCs are also prone to omi...
