Problems solved by technology

[0004] Due to the special environment of the fresh air controller, its power supply is often affected by the wire-controlled fresh air purifier (high-voltage static electricity) during use, which inevitably interferes with the touch IC. The IC will perform a lot of filtering and voltage stabilization, but occasionally there will be false touches

Embodiment Construction

[0020] Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. These embodiments are only typical examples of applying the technical solutions of the present invention, and all technical solutions formed by adopting equivalent replacements or equivalent transformations fall within the protection scope of the present invention.

[0021] The invention discloses a program control method for fresh air controller touch buttons, such as figure 1 As shown, the program control method includes the following steps:

[0022] S1: After the MCU is initialized, the MCU refers to the micro control unit. After the system is initialized, the system timer is turned on. Since the timer can run independently of the MCU, it does not occupy the resources of the MCU. After the MCU initialization is completed, the button scanning starts, and the error correction function is processed first. The er...

Abstract

The invention discloses a program control method for a touch key of a fresh air controller. The method comprises the following steps that: S1: after completing initialization, a MCU judges whether a key value is equal to a previous key value, and if the MCU judges that the key value is unequal to the previous key value, a timer is interrupted, counting is subjected to zero clearing, the key value is stored, and returning is carried out again to carry out error correction function processing; and S2: if the MCU judges that the key value is equal to the previous key value, whether the key value is valid is judged, if the key value is judged to be invalid, the timer is interrupted, counting is subjected to zero clearing and returning is carried out again to carry out error correction function processing, and if the key value is judged to be valid, the next step is carried out. The technical scheme of the invention solves the problem of false touch; and a touch control program of the fresh air controller is subjected to special processing which includes operations of preventing shaking, counting, correcting errors and the like, so that in the using process of the fresh air controller, a power supply of the fresh air controller cannot be influenced by the drive-by-wire fresh air controller, a touch IC is interfered and meanwhile, the service life of the fresh air controller is also greatly prolonged.

Description

technical field [0001] The invention relates to a program control method for touching keys of a fresh air controller, belonging to the technical field of fresh air systems. Background technique [0002] The fresh air controller is a multifunctional home intelligent air quality and environmental monitoring and control product, which can effectively monitor the real-time changes of indoor air quality and temperature and humidity in real time, and intelligently control the fresh air system to monitor the indoor air quality and ambient temperature and humidity. Adjustment, always maintain the best indoor air quality and environment. [0003] Touch keys are widely used in home appliances due to their relatively long service life and high-grade appearance. However, due to its high requirements on the stability of the power supply, if there is a large ripple during use, it is easy to be misoperated. If the distance from the touch source to the panel fluctuates at the critical poi...
