Embodiment Construction
[0043] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0044] The embodiment of the present invention provides a device discovery method, such as figure 1 As shown, the method performs the following steps:
[0045] Step 1: determining the first Internet Protocol IP address in the preset URL range configured by the user;
[0046] Step 2: sending a device search request with the first IP address as the destination address;
[0047] Step 3: Obtain device information of all terminal devices according to the received feedback information sent by the terminal device corresponding to the first IP address based on the device search request.
[0048] The working principle of the above technical solution is: in the step 2, the ...

The present invention provides a device discovery method and system. The method performs the following steps: Step 1: Determine the first Internet Protocol IP address in the preset network address range configured by the user; Step 2: Use the first Internet Protocol IP address as The destination address sends a device search request; Step 3: Obtain device information of all terminal devices according to the received feedback information sent by the terminal device corresponding to the first IP address based on the device search request. According to the method of the present invention, the first Internet Protocol IP address in the preset network address range configured by the user is determined, and the device search request is sent with the first Internet Protocol IP address as the destination address, and then according to the received IP address corresponding to the first Internet Protocol The terminal device with the IP address obtains the device information of all terminal devices based on the feedback information sent by the device search request, improves the efficiency of the communication device in device discovery, and improves the stability of device discovery.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a device discovery method and system. Background technique [0002] When adding multiple front-end IPCs (IP Cameras, network cameras), when the device and the IPC are located in a network based on DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol), the device scans out the IPCs located in the network, and will scan Add the IP address of the IPC to the management list, for each IPC in the management list, obtain the video information of the IPC, determine whether to add the IPC, if not, delete the IPC from the management list. [0003] In an unsubnetted network, the central management node can complete the discovery of all sensor nodes in the network through the above-mentioned simple broadcast (multicast), but this is not applicable in a subnetted network, broadcast (multicast ) message will be shielded by the subnet router so that sens...
