Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0034] In the prior art, in the practical application of realizing device state transition based on the relationship between external voltage and light transmittance, it is necessary to add a photosensor to detect the transmittance, which is cumbersome to operate, high in cost, and hinders the field of view. Generally, a square wave with alternating positive and negative voltages is used to switch the device between coloring and fading, so as to adjust the light transmittance of the device. This method has the problem that the voltage is too high to cause damage to the dev...

Abstract

The invention relates to a control method and system of an electrochromic device, computer equipment and a storage medium. The control method comprises the steps of according to the difference between the initial state and the expected state of the electrochromic device, applying an initial voltage in the corresponding direction to the electrochromic device; from the initial voltage, reducing a voltage value applied to the electrochromic device to reach an expected state; and applying a maintaining voltage, wherein the maintaining voltage is obtained according to the light transmittance of the electrochromic device in the expected state. By means of the control method, the direction of the voltage needing to be applied for device state transition can be rapidly and accurately judged, and on the premise that the device is protected against loss, rapid transition and accurate regulation and control of the state of the electrochromic device are achieved.

Description

technical field [0001] The present application relates to the technical field of electrochromic devices, in particular to a control method, system, computer equipment and storage media for electrochromic devices. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties (reflectivity, light transmittance, absorptivity, etc.) of materials undergo stable and reversible changes under the action of an external electric field, and appear as reversible changes in color and transparency in appearance. Devices made of electrochromic materials are called electrochromic devices, which generally consist of at least five layers of thin films on a transparent substrate, including the underlying transparent conductive layer, electrochromic layer, ion conducting layer (electrolyte layer), and ion storage layer. and the top transparent conductive layer. Under the action of an external electric field, the ions in the ion storage layer are driven thro...
