Regulation and control method for electrochromic device and electronic device

An electronic device, comprising:

• a processor and a memory, wherein the memory is coupled to the processor, and the memory is configured to store a computer program code, wherein the computer program code comprises computer instructions which, when executed by the processor, cause the electronic device to perform the following:
• receiving a transmittance regulation signal of the electrochromic device, wherein the transmittance regulation signal carries a target gear value for transmittance of the electrochromic device, wherein the electrochromic device is configured with a plurality of gears and the plurality of gears is set in accordance with a changing order of the transmittance of the electrochromic device;
• acquiring a current gear value of the electrochromic device;
• and
• determining, according to the target gear value, the current gear value, and a stable state gear value of the electrochromic device, a target voltage regulation manner to regulate the transmittance of the electrochromic device according to the target voltage regulation manner;
• wherein a stable state of the electrochromic device is a state corresponding to an open circuit voltage of 0 V of the electrochromic device;
• wherein the determining, according to the target gear value, the current gear value, and the stable state gear value of the electrochromic device, the target voltage regulation manner comprises:
• determining a switching direction of the transmittance of the electrochromic device according to the target gear value, the current gear value, and the stable state gear value;
• and
• wherein the switching direction of the transmittance of the electrochromic device comprises:
• the current gear value is located on a side of the stable state gear value opposite to a side of the stable state gear value where the target gear value is located on, or, the current gear value is located on a side of the stable state gear value same as a side of the stable state gear value where the target gear value is located on.
