First, the central air conditioning concentrator produced by the background:

Central air-conditioning system is an important component of modern buildings, is the main monitoring object of building automation system is also one of the main management contents of building intelligent system. Central air-conditioning energy consumption accounted for more than 50% of the total building energy consumption, building automation system energy-saving focus. Central air-conditioning through computer centralized control, to achieve the central air-conditioning energy measurement billing, monitoring and management, in order to meet the indoor environment comfort conditions, to minimize the central air-conditioning operation energy consumption, to achieve a balance of comfort and energy saving. The system can monitor the temperature and energy condition of each area or room in real time, and can be remotely intervened and regulated for rooms with low temperature, easily reaching reasonable energy management.

Second, the central air conditioning concentrator to achieve the function

Central air conditioning concentrator for all indoor machines for centralized switching, setting, monitoring and management, can support mobile phone APP remote monitoring of air conditioning status. Record air conditioning switch machine time, temperature, fault and other parameters, and can calculate and count the power consumption of each indoor machine, easy to analyze and manage energy saving and provide household billing data. And historical data power-down does not disappear, hardware, cloud multi-data protection. For customers with prepaid features, customized prepaid plans can be provided to automatically lock the air conditioner after the pre-existing air conditioning charges have been used. Fully from the air-conditioning users, property management, air-conditioning maintenance operation point of view, to obtain their own required data.

Central monitoring and management of all air conditioners in a single unit or group includes:

• 1, Real-time query and control: switch machine status, operating mode, wind speed and temperature;
• 2, Switch machine history query;
• 3, Alarm fault history query;
• 4, Cumulative run time query;
• 5, Energy consumption data statistical analysis;
• 6, Prepaid function.
• 7, Central air conditioning billing function.

Third, the central air conditioning concentrator use scene

1, Central air-conditioning household metering

Self-locking: When the user does not pay the air conditioning fee, the air conditioning can be locked through the system, the user can not lift it.

Electricity data measurement accuracy: air conditioning data every 1 minute, every 5 minutes storage, in order to ensure accuracy at the same time, the minimum limit to prevent data omission. Computer anomalies do not affect billing, air conditioning power statistics and allocation data will be stored in real time on the gateway FLASH memory, monitoring computer power down or failure does not affect normal billing. The multi-stage distribution storage of electricity charge data uses air-conditioned data collector, centralized data collector, manages the redundant storage of computer triple data, and avoids data loss caused by computer hard disk failure and other problems.

2, Intelligent control energy-saving system

IoT temperature and humidity transmission technology: Use IoT technology to transfer temperature and humidity values collected in the room to the cloud.

According to the room temperature value and humidity value, intelligently adjust the room temperature, not only to meet the user's physical comfort but also to achieve energy-saving effect.

Air conditioning operation tracking technology: according to user needs to set up automatic switch machine, no manual switch machine.

3, Smart home

At the same time, the central air conditioning, new air, underfloor heating connected to the smart home system, so as to achieve a gateway to three devices at the same time control.

To solve the problem that the VRV central air conditioning protocol is not open and the smart home protocol is not unified, all air conditioning is converted into the same protocol, the interfaces are: mesh, WIFI, KNX, RS485, UART, etc., support Zigbee and other wireless module embedding, all communication interface can support air conditioning, underfloor heating, new wind;

Fourth, FETMX6UL-C core board recommended reasons

• 1, Support multi-serial port;
• 2, Support can interface;
• 3, Support 2 network outlets, local communication and external communication separate;
• 4, Integration of a variety of protocols: KNX (self-developed KNX protocol module), Bacnet, Modbus, TCP/IP;
• Down: connect external data collectors or device terminals via network outlets, WIFI, KNX, RS485, UART, zigbee and other modules;
• Up: through the network port or 4G, upload data to the local server and cloud platform, cloud platform data processing through the interface or mobile phone APP to achieve the control of the device and data monitoring.
