1. Program introduction
This solution is an air conditioner remote monitoring solution based on the Industrial Internet of Things. It reads the air conditioner controller through the 4G gateway and uploads the data to the cloud platform. Users can use their mobile phones and computers to remotely view relevant data and remotely control. At the same time, this solution also supports phone, SMS, WeChat, and email alarm functions. When an abnormality occurs in the air conditioner, the system will automatically send an alarm message to the administrator to facilitate timely handling of abnormal situations.
2. System architecture
This solution is mainly divided into four parts: air conditioning controller, 4G gateway, cloud platform and alarm system. The air conditioning controller communicates with the 4G gateway through the Modbus RTU communication protocol, and the 4G gateway uploads the read data to the cloud platform. When an abnormality occurs in the air conditioner, the alarm system will automatically send alarm information to the administrator, who can receive it through phone calls, text messages, WeChat, emails, etc.
3. Hardware equipment
Air conditioning controller : Air conditioning controller with Modbus RTU communication protocol
4G gateway : a gateway device that uses 4G network for data transmission
Cloud platform : Use cloud platforms such as Alibaba Cloud for data storage and remote access
Alarm system : Alarm system that supports phone, SMS, WeChat, and email alarm functions
4. Software implementation
4.1 Modbus RTU communication
The Modbus RTU communication protocol is used for data transmission between the air conditioning controller and the 4G gateway. On the 4G gateway, the data of the air conditioning controller is read through the serial port and uploaded to the cloud platform.
4.2 Data upload
The 4G gateway uploads the read air conditioning controller data to the cloud platform through the 4G network. The cloud platform can use the IoT platform of cloud service providers such as Alibaba Cloud for data storage and management.
4.3 Alarm system
When an abnormality occurs in the air conditioner, the alarm system will automatically send alarm information to the administrator, who can receive it through phone calls, text messages, WeChat, emails, etc. The alarm system can be implemented using third-party service providers such as Alibaba Cloud SMS, WeChat official accounts, etc.
5. Summary
This solution is an air conditioner remote monitoring solution based on the Industrial Internet of Things. It reads the air conditioner controller through the 4G gateway and uploads the data to the cloud platform. Users can use their mobile phones and computers to remotely view relevant data and remotely control. At the same time, this solution also supports phone, SMS, WeChat, and email alarm functions. When an abnormality occurs in the air conditioner, the system will automatically send an alarm message to the administrator to facilitate timely handling of abnormal situations. This solution can improve the use efficiency and management level of air conditioners, and reduce the impact of air conditioner operation failures on production and life.
