Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to an intelligent device for wireless networking and centralized control of HVAC terminal equipment. Background Art

[0002] In public building central air conditioning systems, water-based central air conditioning is widely used in large commercial buildings, hotels, hospitals, and other places. Fan coil units are widely used in terminal systems to achieve heat and cold exchange. These devices are numerous and independent, and daily operation and control are decentralized and haphazard. Without dedicated personnel, they are essentially in a state of random use, resulting in severe energy waste. Networked thermostats, which centrally manage and control traditional thermostats, can effectively solve the problem of centralized management and control of fan coil units in property management.

[0003] Existing conventional thermostats cannot centrally control and manage decentralized fan coil units, and cannot solve the problems of random opening, random setting, forgetting to turn off, and missed turning off. In addition, the functions are relatively simple. Thermostats that use a serial communication bus for network management require laying communication cables for communication, which is cumbersome to use. Therefore, an intelligent device for wireless network centralized control of HVAC terminal equipment is needed to solve the above problems. Utility Model Content

[0009] As a preferred solution, the main control module is used to convert and store the data uploaded from the temperature and humidity detection module, and then transmit it to the gateway through a wired or wireless network and receive various instructions issued by the gateway. The clock module is used to provide precise time through the built-in high-precision clock chip, thereby realizing unified time distribution on the cloud platform.

[0010] As a preferred solution, the valve control module is used to directly control the relay, thereby affecting the high, medium and low states of the terminal valve, as well as the cold and hot selection. The power supply module is used to transform the universal AC220v 50HZ mains electricity into 5V to the relay, and then into 3.3V to the temperature and humidity detection module, valve control module, touch interaction module and main control module.
