Problems solved by technology

In addition, non-contact control can be realized through Bluetooth technology and infrared human-sensing technology, but the cost is very high
[0003] Especially, when people are in places with frequent flow of people (such as waiting rooms, noisy public places such as hotels), the operating states and operating modes such as the target temperature and wind speed required by the air conditioner are constantly changing. If the ambient temperature is relatively high, the target temperature is lower and the wind speed gear is higher. When there are few people and the ambient temperature is lower, the target temperature is higher and the wind speed gear is lower. To meet the ambient temperature requirements of the personnel in the site, special staff are required to continuously adjust the target temperature, which wastes manpower and the adjustment is not accurate enough

Embodiment 1

[0032] This embodiment provides an air conditioner that can realize automatic control, and the air conditioner includes an air conditioner body, a sound collection module disposed on the air conditioner body, a sound processing module, a memory, and a main control module. In this embodiment, the sound processing module is an FFT module. In order to facilitate timing, the air conditioner body is also provided with a timing module.

[0033] For the above-mentioned air conditioner, this embodiment also provides an automatic control method for the air conditioner based on sound signals. Such as figure 1 As shown, the specific steps of the method are:

[0034] Step A, pre-store the effective spectrum range in the FFT module, the effective spectrum range is preferably [10dB, 70dB]. There are four pre-stored spectrum areas in the main control module, which are the first pre-stored spectrum area [10dB, 25dB), the second pre-stored spectrum area [25dB, 40dB), the third pre-stored sp...

Embodiment 2

[0041] This embodiment provides an air conditioner and a control method thereof. The structure of the air conditioner is basically the same as that of the first embodiment, including an air conditioner body, a sound collection module, a sound processing module, a memory and a main control module arranged on the air conditioner body. Its control method is also basically the same as Embodiment 1. The sound collection module of the air conditioner collects the ambient sound and transmits the ambient sound signal to the sound processing module. The sound processing module converts the environmental sound signal into a frequency domain signal and stores it in the memory. The module controls the switch of the air conditioner according to the frequency domain signal or controls the air conditioner to operate according to the operating state corresponding to the frequency domain signal.

[0042] The difference is that the main control module of this embodiment extracts the ambient tem...

Abstract

The invention discloses an automatic air conditioner control method based on a sound signal and an air conditioner and relates to the technical field of refrigerating and heating equipment. The automatic air conditioner control method is designed for solving the problems that existing air conditioners which can be controlled automatically are low in control precision, high in equipment cost and the like. The automatic air conditioner control method based on the sound signal comprises the steps that a sound collection module of the air conditioner collects environment sounds and transmits the environment sound signal to a sound processing module; the sound processing module converts the environment sound signal into a frequency domain signal and stores the frequency domain signal into a storage device; a master control module controls the air conditioner to be turned on and off or controls the air conditioner to run in the operation state and / or the operation manner corresponding to the frequency domain signal according to the frequency domain signal. The invention further provides the air conditioner adopting the control method. According to the air conditioner control method, air conditioner parameters do not need to be manually set, automatic control over the air conditioner is achieved, a user can use the air conditioner conveniently, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heating equipment, in particular to an automatic control method of an air conditioner based on sound signals and the air conditioner. Background technique [0002] The switch of the air conditioner and the conversion of the operating mode are generally operated by controllers such as remote controllers and wire controllers. The buttons on the panel of the air conditioner control the switch and operation mode of the air conditioner. In the prior art, the operator must control the air conditioner through the buttons on the controller or the keys on the indoor unit, and the operator sends control commands through the control buttons. In addition, non-contact control can be realized through Bluetooth technology and infrared human-sensing technology, but the cost is very high. [0003] Especially, when people are in places with frequent flow of people (such as waiting rooms, noisy public pl...
