The processor is used for selecting first sample data comprising a larger temperature value from the multiple groups of sample data, and taking the control time in the first sample data as the first control time.
Next, a control method of the electrochromic device is explained. The control method can be used for controlling the electrochromic device, can also be used for controlling the electrochromic device 32 arranged on the electronic equipment 100, and can also be used for controlling the electrochromic devices arranged on other electronic equipment. Please refer to fig. 9, which discloses a flowchart of a control method according to an embodiment of the present application. The control method may include:
step S0901: and if the electrochromic device accords with the preset electrifying requirement in the first state, acquiring a first temperature and control time algorithm of the electrochromic device.
For the electrochromic device, the electrochromic material is arranged in the electrochromic device and can show different color changes under different control voltages. For example, applying a control voltage to an electrochromic device may cause the electrochromic device to assume a colored state or a bleached state. Wherein the colored state is to exhibit a color such that the electrochromic device achieves a certain standard, e.g., achieves an opaque color. The faded state is a transparent state.
In order to maintain the color state or the fading state of the electrochromic device, the open circuit voltage of the electrochromic device needs to be maintained within a certain voltage range. For example, an initial control voltage is applied to the electrochromic device, and the electrochromic device is electrified, so that coloring of the electrochromic device is realized; in the electricity supplementing operation, the open-circuit voltage of the electrochromic device needs to reach the standard of the upper color state, so that the electrochromic device can be always in the upper color state. For example, an initial control voltage is applied to the electrochromic device, and the electrochromic device is electrified, so that the color fading of the electrochromic device is realized; in the electricity supplementing operation, the open circuit voltage of the electrochromic device needs to reach the standard of the fading state, so that the electrochromic device can be always in the fading state. For example, an initial control voltage is applied to the electrochromic device, and the electrochromic device is electrified, so that coloring of the electrochromic device is realized; in the electricity supplementing operation, the open circuit voltage of the electrochromic device needs to reach the standard of the fading state, so that the electrochromic device can be in the fading state. For example, an initial control voltage is applied to the electrochromic device, and the electrochromic device is electrified, so that the color fading of the electrochromic device is realized; in the electricity supplementing operation, the open-circuit voltage of the electrochromic device needs to reach the standard of a fading state, so that the electrochromic device can be in a coloring state.
For an electrochromic device, the open-circuit voltage and the transmittance of the electrochromic device are in a nonlinear positive correlation. In addition, electrochromic devices are similar to a capacitor and are not completely isolated, and thus have a certain amount of natural leakage. Then, in the presence of natural leakage rate, the open-circuit voltage of the electrochromic device cannot be maintained after the initial control voltage is powered on. In the maintenance state of the electrochromic device, the open circuit voltage is lower as the time is longer, and the open circuit voltage approaches zero when the time is sufficiently long.
Therefore, in order to maintain the upper color state or the fading state of the electrochromic device, the electrochromic device needs to be powered up frequently, so that the open-circuit voltage of the electrochromic device is recovered, and the upper color state or the fading state of the electrochromic device is maintained. For example, the electrochromic device is in the upper color state, and can be subjected to a complementary operation so as to maintain the upper color state or the lower color state. For example, the electrochromic device is in a bleached state, and can be subjected to a complementary operation so as to maintain the bleached state or the bleached state.
In one embodiment, the first state may be a colored state or a faded state.
Here, the preset power-on condition may be controlled by a user, that is, when a control instruction is received, the preset power-on condition may be considered to be satisfied. Of course, periodic energization is also possible. For example, at intervals of time, e.g., 12h, 24h, 48h, etc., it is considered to reach the preset energization condition. Of course, the preset power-on condition may also be an open-circuit voltage of the electrochromic device, and when the open-circuit voltage is lower than the open-circuit voltage threshold, it is considered that the preset power-on condition is reached. Of course, the preset power-on condition may also be a control command input by the signal input device 101 (shown in fig. 6). The preset power-on condition may be other conditions, such as ambient light intensity, on/off of the electronic device, and the like. And will not be described in detail herein.
It is to be understood that the preset power-on condition may include a preset power-on condition and a preset power-on condition. The color change can be carried out when the preset electrifying condition is reached, for example, the upper color state and the lower color state are mutually converted. The state can be maintained when the preset power supply condition is reached, for example, the first state is the coloring state, and the coloring state is maintained, for example, the first state is the fading state, and the fading state is maintained.
In one embodiment, the control time algorithm is configured to fit a plurality of sets of sample data including the control time and the temperature of the electrochromic device using a least squares method.
In this embodiment, a use experiment is performed on a standard electrochromic device, so that the standard electrochromic device performs power-on operation or power-on operation at different temperatures under the same control voltage. The preset energization condition in the above-described embodiment may be adopted. Multiple sets of sample data were measured during the experiment. The sample data may include temperature, control time. Of course, the sample data may also include control voltages.
And finding different control time at different temperatures in the sample data, and performing function fitting on the temperature and the control time by adopting a least square method so as to obtain a control time algorithm. When the electrochromic device is conveniently controlled, the corresponding control time can be obtained directly according to the temperature so as to carry out power-on operation or power-supplementing operation on the electrochromic device.
In the fitting process, known discrete groups of sample data comprising the control time and the temperature of the electrochromic device are placed in a function, and the fitting coefficient of each temperature value in the function is adjusted, so that the difference (least square meaning) between the function and the control time in the known discrete groups of sample data is minimum.
Step S0902: and acquiring a first control time by using the first temperature based on a control time algorithm.
In the first control time obtaining process, the first temperature can be directly substituted into the control time algorithm to obtain the first control time. Of course, the first temperature may be further processed and then substituted into the control time algorithm to obtain the first control time.
Step S0903: and applying a control voltage to the electrochromic device within the first control time to enable the electrochromic device to be in a second state.
And performing electricity supplementing operation on the electrochromic device, and applying control voltage to the electrochromic device for a first control time. The system or electronic device may assume that the electrochromic device is in the second state after the power-up operation.
The second state is a colored state or a faded state. The first state may be the same as the second state. The first state may also be different from the second state.
The first state is different from the second state. For example, an electrochromic device may be in a colored state and remain in a bleached state after power-up. For example, an electrochromic device may remain in a bleached state and remain in a colored state after power-up.
The first state is the same as the second state. For example, the electrochromic device may be in the colored state and remain in the colored state after power is applied. For example, an electrochromic device may be in a bleached state, which is maintained after power is applied.
In one embodiment, please refer to fig. 10, which discloses a flowchart of a control method in another embodiment of the present application. Before step S0901, the control method further includes:
step S1001: and if the electrochromic device accords with the preset electrifying requirement in the first state, acquiring the control voltage.
For an electrochromic device, the electrolyte mass transfer efficiency of a discoloring material layer in the electrochromic device is increased due to overhigh temperature and overhigh voltage, the efficiency of charge transfer is correspondingly improved, and further the reaction speed is increased, so that the requirements of charge and reaction can be met by shorter control time and lower control current under the condition of overhigh temperature of the electrochromic device, and the service life of the electrochromic device is influenced due to overhigh voltage and overlong charging time. In addition, too high a voltage will cause transient currents to damage the electrochromic device to some extent. Moreover, the mass transfer efficiency of the electrolyte in the color-changing material layer is reduced due to the reduction of temperature, and the mass transfer efficiency and the conduction efficiency are reduced, so that the response time is too long. Therefore, the corresponding voltage and the response time are determined for different temperatures. So as to more efficiently, safely and accurately control the electrochromic device. Blind manual setting is avoided.
In the embodiment, a use experiment is performed on the standard electrochromic device, so that the standard electrochromic device performs power-on operation or power-supplementing operation at different temperatures under different control voltages. The preset energization condition in the above-described embodiment may be adopted. Multiple sets of sample data were measured during the experiment. The sample data includes temperature, control time, and control voltage.
The temperature is not the same as the control time at different control voltages found in the sample data. Therefore, different control time algorithms can be formed for different control voltages based on temperature and control time. And then the control time algorithm and the control voltage form a preset corresponding relation such as an index relation. The electrochromic device can be controlled more accurately. The electrochromic device is more accurately powered on or supplemented with electricity.
It is understood that the control voltage may be any value in the data measured in the experiment, and the data measured in the experiment may be stored in the related electronic device, or may be stored in the corresponding memory, and when necessary, the data is retrieved to control the voltage output by the electronic device to control the electrochromic device. Of course, the control voltage may also be a single value, and may be stored in the associated electronic device, or may be stored in a corresponding memory, and when necessary, the control voltage data may be retrieved to control the voltage output by the electronic device to control the electrochromic device. In addition, the voltage of the electronic equipment output control electrochromic device can also be non-adjustable voltage, namely the control voltage is formed by the property limitation of devices such as electronic equipment, batteries and the like.
Accordingly, step S0901 may include:
step S1002: and if the electrochromic device accords with the preset power-on requirement in the first state, acquiring a control time algorithm of which the first temperature and the control voltage have a preset corresponding relation.

Therefore, when such electrochromic devices are in a faded state, the replenishing operation described in the above embodiments can be employed. When the electrochromic device is in a colored state, the electricity supplementing operation can be completed in a mode of enabling the open-circuit voltage to be 0 through short-circuit. Of course, the power supplementing operation in the above embodiment may be adopted.
In one embodiment, the control time algorithm is configured to fit a cubic function to a plurality of sets of sample data including control time and temperature by a least squares method.
Of course, the control time algorithm may be a quadratic function, a quartic function, or a quintic function, in addition to a cubic function. And will not be described in detail herein.
