Internet of Things subsystem integrated access method, Internet of Things system, device and medium

The invention discloses an Internet of Things subsystem integrated access method, an Internet of Things system, equipment and a medium. The method is applied to an Internet of Things platform, the Internet of Things platform is connected with a plurality of subsystems, each subsystem is connected with a plurality of sub-devices, and the method comprises the steps that the Internet of Things platform calls a customized subsystem universal interface to communicate with the subsystems so as to complete control over the subsystems; and/or the Internet of Things platform calls a self-defined sub-device universal interface to communicate with the sub-device so as to complete control of the sub-device. Therefore, a unified access mode is realized, and the control program can adapt to access of subsystems and sub-devices of different manufacturers only through one-time coding. 本申请公开了一种物联子系统集成接入的方法、物联网系统、设备及介质。方法应用于物联网平台，物联网平台连接多个子系统，每个子系统连接多个子设备，方法包括步骤：物联网平台调用自定义的子系统通用接口，与子系统进行通信，以完成对子系统的控制；和/或物联网平台调用自定义的子设备通用接口，与子设备
