Data access method, data receiving method, device, system, equipment and medium

Abstract

This application discloses a data access method, a data receiving method, an apparatus, a system, a device, and a medium. The data access method is applied to a gateway and includes: acquiring configuration information of cloud device components; the cloud device component configuration information includes a system shadow and device component shadows corresponding to the real target system, the shadows containing communication connection information between the device components and the gateway; establishing a communication connection between the gateway and the corresponding device components based on the communication connection information; acquiring measurement data of multiple device components, mapping the measurement data of each device component to the device component shadow, obtaining device component shadow data; integrating the multiple device component shadow data based on the system shadow, and sending the obtained system data to the cloud device. The scheme disclosed in this application integrates the data of each device component in the real system into the real system's system data based on the device component shadow and the system shadow before reporting it to the cloud device, thereby reducing the complexity of system access and management.
