The Ebyte IoT management platform, because of its simplicity, easy operation and stable operation, takes it as the role of the "Smart Management System" in the "Smart Fresh Air System" project, and completes the implementation of the Smart Fresh Air System project through the following steps:1. Device accessWhere environmental data collection is required, complete the installation and access of relay equipment. CAN ModuleThe relay device is used to connect the sensor and the intelligent management system to realize the transmission of data and control instructions. (For the relay device access process, please refer to the device access and configuration tutorial)2. Collect data and reportInstall the required sensors (such as temperature, humidity, and air quality detection) at the designated location, and connect them to the relay device. The relay device starts data collection and reporting according to the configuration parameters in the smart management system.3. Process scheduling (data processing in the workflow engine)After the data IO service of the smart management system receives the data, it will be delivered to the data processing process for processing. Such as: data operation, data storage, event triggering, etc.a), alarm (send alarm notification)When the data of the data point meets the user's preset value of the alarm trigger for the data point, the trigger node in the process will trigger the alarm event, and call the processing rules for the event to complete the subsequent actions, and send an alarm notification to the designated contact people and so on.b), linkage (send commands to the device)When the data of the data point meets the user's preset value of the linkage trigger for the data point, the trigger node in the process will trigger the linkage event, and call the processing rule for the event to complete the subsequent behavior, and issue the linkage instruction to the specified equipment, etc. In this scheme, the linkage function is mainly used to issue the start, stop and adjustment commands of the fresh air system to the control system of the fresh air system, so as to realize the linkage reaction after the environmental state changes.Of course, in specific applications, more sensors or data acquisition terminals (such as cameras with face recognition) are needed to realize the functions of person identification and preference control. Wireless modem The setting method is similar to the above, so no special description will be given.
