Embodiment 1
[0034] Such as figure 1 As shown, an air-conditioning control method includes the following steps,
[0035] Obtain the instantaneous voltage Vac of the AC input terminal; judge whether there is no zero-crossing signal according to the instantaneous voltage Vac of the AC input terminal; running load; otherwise, continue to obtain the instantaneous voltage Vac at the AC input.
[0036] The present invention effectively solves the problem of surge current generated when the air conditioner is powered off in a short period of time, and improves the reliability of the entire air conditioner.
Embodiment 2
[0038] Such as figure 2 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that an air-conditioning control method specifically includes the following steps:
[0039] S1. Obtain the AD sampling value Z of the AC input terminal in real time 1 ;
[0040] Specifically, because the voltage waveform at the AC input terminal is an input waveform with a sine wave change. Therefore, to obtain the AD sampling value Z of the AC input terminal in real time 1 ,Z 1 The range 0-1023.
[0041] It should be noted that by obtaining the voltage of the AC input terminal and then judging the slow start, there is no need to install any additional equipment or devices, which can effectively save costs.
[0042] S2, through the value of the AC input voltage V X AD sampling value Z 1 Calculate the instantaneous voltage Vac at the AC input terminal;
[0043] V ac =(Z 1 -2 n-1 ) / 2 n-1 A 1 ;
[0044] Among them, Z 1 The range is: 0-1023, n is the num...
Embodiment 3
[0060] A control device, including a relay module, which is used to change the state of the circuit; when the power is off, the circuit connection on both sides is disconnected; when the power is on, the circuit connection on both sides is closed;
[0061] The control module obtains the instantaneous voltage Vac of the AC input terminal; judges whether there is no zero-crossing signal according to the instantaneous voltage Vac of the AC input terminal; if yes, then judges that the air conditioner is powered off, and sends a power-off signal to the control device, and the control device turns off the relay module and the load of the air conditioner; otherwise, continue to obtain the instantaneous voltage Vac of the AC input terminal; after judging that the air conditioner is powered off, continue to determine whether the instantaneous voltage Vac of the AC input terminal has a zero-crossing signal, and if so, the timing has a zero-crossing signal duration of T X , the duration ...
