S14: and if response information returned by the target communication address is received, analyzing the response information to obtain the equipment type, and recording the target communication address and the equipment type.
If the target communication address has the device, the device sends response information corresponding to the request frame to the monitoring host according to a pre-agreed communication protocol, that is, if the monitoring host receives the response information returned by the target communication address, the device exists in the target communication.
After receiving the response information returned by the target communication address, the monitoring host may analyze the response information to obtain the device type (temperature and humidity device, air conditioner, fan, etc.) of the device in which the target communication address exists, and may record and store the target communication address and the analyzed device type to automatically determine the connection relationship between the monitoring host and the device, and then, execute step S15.
If no device exists in the target communication address, the monitoring host does not receive the response information returned by the target communication address, and in this case, step S15 may be executed, that is, if the response information returned by the target communication address is not received, step S15 is directly executed.
In order to further improve the efficiency of determining the connection relationship between the monitoring host and the device, the monitoring host may determine whether response information returned by the target communication address is received within a preset time period, that is, if response information returned by the target communication address is received within the preset time period, the monitoring host may analyze the response information and record the target communication address and the device type, and then execute step S15, and if response information returned by the target communication address is not received within the preset time period, the monitoring host may directly execute step S15, so as to avoid the occurrence of a situation of waiting for the response information for a long time, thereby improving the efficiency of determining the connection relationship between the monitoring host and the device.
