Description

Device discovery method and electronic device Technical Field The present application relates to the technical field of electronic devices, and in particular, to a device discovery method and an electronic device. Background Currently, the internet application is expanding from the consumption field to the production field, and is deeply fused with the economic fields of the entities such as industry, energy and the like. The new generation industrial network takes' equipment networking and network interconnection (internet protocol, IP) as key characteristics, and each equipment can be accessed into the industrial network through an Ethernet or wireless fidelity (WIRELESS FIDELITY, wi-Fi) network, so that the new generation industrial network has the capabilities of fully sensing data deeply, transmitting interactive data in real time and deploying artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) computing power as required. In an actual industrial application scenario, a scenario that data collection or service cooperation needs to be performed between 2 short-distance devices through a network often occurs, for example, a machine tool a needs to perform service cooperation with a machine tool B beside the machine tool a. Although all of the 2 machine tools are connected to the network through an ethernet network or Wi-Fi, the service cooperation of the two requires one party to discover the other, i.e. the device discovery. With the increasing production scale, the number of devices connected in the same network is increasing, and how to implement high-efficiency devices in a large number of devices has been found to be a problem to be solved urgently. Disclosure of Invention The application provides a device discovery method and electronic equipment, which can discover the short-distance devices in the same network more conveniently and rapidly aiming at the scene of connecting a plurality of devices in the same network, and are beneficial to improving the discovery efficiency of the short-distance devices in the same network. In a first aspect, the application provides a device discovery method, which can be applied to a first device, wherein the first device and a second device are located in a first network, and the device discovery method comprises the steps of receiving a first broadcast message through the first network, wherein the first broadcast message comprises first identification information of the second device, and sending a first response message to the second device through the first network when the first message is received through a wireless network and second identification information included in the first message is matched with the first identification information, wherein the first response message is a response to the first broadcast message. Based on the technical scheme, after the first device receives the first broadcast message through the first network, the first response message can be replied only when the first message is received and the second identification information included in the first message is matched with the first identification information, but the first response message is not replied for all broadcast messages, so that the discovery device is initiated to distinguish the short-distance device from the long-distance device, and the device discovery efficiency is improved. In some possible implementations, when a first message is received over the wireless network and the second identification information included in the first message matches the first identification information, sending a first response message over the first network to the second device includes sending the first response message over the first network to the second device when the first message is received over the wireless network and the second identification information included in the first message is the same as the first identification information. With reference to the first aspect, in certain implementation manners of the first aspect, the method further includes ignoring the first broadcast message when the first message is not received through the wireless network. With reference to the first aspect, in certain implementations of the first aspect, before receiving the first message over the wireless network, the method further includes sending a second message over the wireless network, the second message for discovering devices surrounding the first device. Based on the technical scheme, the first device can actively search the surrounding devices to acquire the second identification information of the surrounding devices, and can selectively send the first response message by judging whether the second identification information is matched with the first identification information in the first broadcast message, so that the distance of the surrounding devices can be further differentiated. With reference to the first aspect, in certain implementations of the first aspec
