Problems solved by technology
The key components of the FFU unit are the fan and the control device. Most of the existing control devices use conventional control methods, including manual multi-stage speed regulation, distributed control speed regulation, and computer group control. These control methods require manual intervention. And control, if it is to be regulated on site, it will bring inconvenience to the operation, the staff need special clean clothes and gloves to enter the clean room, it is difficult to realize the control operation

The invention relates to a FFU intelligent voice control device and a control method, and belongs to the technical field of air purifying equipment control. Aiming at making-up of defects in the priorart, the FFU intelligent voice control device and control method are provided. An intelligent voice identifying unit is provided for controlling a fan control unit; and data is transmitted through alocal area network to realize synchronous intelligent voice group control of multiple FFUs. The FFU intelligent voice control device and control method have the following beneficial effects: the efficient and intelligent control of the FFUs can be realized through specific voice without needing manual setting and operation by workers, so that the control device and the control method are suitablefor application in such engineering as clean rooms and clean factory buildings, can meet efficient control application demands in different purifying application places, and achieve excellent economicand social benefits.
Description
technical field [0001] The invention relates to an FFU intelligent voice recognition control device and a control method, belonging to the technical field of air purification equipment control. Background technique [0002] The full name of FFU in English is (Fan Filter Unit), and the Chinese name is fan filter unit, also known as fan filter unit. The FFU fan filter unit can be modularly connected and used. The use of FFU is widely used in clean rooms, clean benches, clean production lines, assembled clean rooms and local class 100 applications. FFU is equipped with primary and high-efficiency two-stage filters. The fan sucks the air from the top of the FFU and filters it through primary and high-efficiency filters, and the filtered clean air is sent out at a uniform speed of 0.45M / S±20% on the entire air outlet surface. Suitable for obtaining a high level of cleanliness in various environments. [0003] As a new type of fan purification control device, the fan filter uni...
