Classroom Air Conditioning Energy Saving Monitoring Solution
Achtergrond
Schools, as large public institutions, have numerous and varied buildings. Currently, air conditioning is installed in almost all school buildings, resulting in a large number of units widely distributed. The use of air conditioning leads to energy waste and a lack of unified management. It is necessary to implement refined management and energy consumption control of the school's air conditioning system to achieve energy conservation and emission reduction.
Eisen van de klant
- Gegevensverzameling
The system needs to remotely collect real-time operating status (on/off, cooling/heating mode) and temperature and humidity sensor data for each air conditioner as the basis for intelligent start/stop decisions.
- Data Integration
The system must support data integration with the school's academic management system via a standard API interface, automatically synchronizing class schedules for all classrooms.
- Afstandsbediening
The system needs to remotely collect real-time operating status (on/off, cooling/heating mode) and temperature and humidity sensor data for each air conditioner as the basis for intelligent start/stop decisions.
- Visuele analyse
The platform needs to visually display the real-time status (online, offline, running, off, abnormal) of all air conditioners, organized by floors and teaching buildings.
Technische oplossing
This solution utilizes the ZHC493C 4G RTU device from IOTROUTER for air conditioner and sensor data acquisition, data transmission, and remote control. The IOTROUTER Cloud platform is used for online monitoring and data analysis. The cloud platform seamlessly integrates with the school's academic affairs system to obtain real-time classroom usage information. During non-class periods, the platform automatically sends a power-off command to the corresponding classroom's DTU.
A remote control switch is added to the power supply side of the existing air conditioner control panel to control the power on/off of the control panel, thus enabling control of the air conditioner's on/off state according to preset time periods.
The RTU monitors the actual operating current of the air conditioner through digital input (DI) to determine its status; it remotely controls the power supply by connecting a relay output (DO) contact to the air conditioner's power control circuit. The RTU device connects to the server via GPRS, supporting multiple devices simultaneously accessing the internet.
ZHC493C 4G RTU Introduction
The ZHC493C is a CAT1 LTE wireless remote control RTU with "remote control" at its core, balancing flexibility and reliability. It supports JSON, Modbus RTU/TCP protocols, integrates one relay output, two dry/wet node inputs, and one analog input (4~20mA), and provides TCP_Client/MQTT_Client functionality.
ZHC493C fully considers user needs:
1)It supports timed triggering, data triggering, and periodic reporting;
2)It has local logic and inter-device logic control capabilities;
3)A hardware watchdog ensures long-term stable operation;
4)Network registration packets and heartbeat mechanisms guarantee reliable communication;
5)Remote configuration and upgrades make maintenance more convenient;
IOTRouter focus on user experience, making system integration simpler and operation more intuitive, helping customers easily achieve remote and local control. The ZHC493C is not just a device, but a highly efficient and reliable remote monitoring solution.
