Abstract:A Remote Control System for the new type of absorption refrigeration unit is designed which gains access to the cloud platform. The system is designed to solve the problem of distributed sensors, multi-protocol of heterogeneous networks and cloud platform access for local devices, which achieves the data sharing and remote monitoring between cloud platform and control filed. Through field bus technology, the intelligent node is designed and the CAN sensor network is constructed in the control field. Through the embedded technology, an embedded cloud gateway is designed which uses the data cache frame as the buffer for the multi-protocol conversion. The wireless module is used to establish the access to the cloud platform and use the EDP protocol to connect the control field with the cloud platform. In the cloud platform, the cloud monitoring platform of the refrigeration unit is designed. Through the registration of device and monitoring interface design, the access equipment is mapped in the cloud platform, and the data from the control field is automatic updating in the cloud platform. The system uses the method of cloud platform access for local devices, which completes the experiment data sharing and remote monitoring for new absorption refrigeration.
