[0001] This invention relates to the field of glass technology, and in particular to a driving system and method for smart glass. Background Technology

[0002] Smart glass is a type of glass that can change its light transmittance (i.e., gradually switch between a transparent and opaque state) through methods such as electronic control, temperature control, light control, or pressure control. Currently, the main control method for smart glass is manual control, requiring operators to manually control the glass via an app, remote control, or control switch.

[0003] While existing dimming glass control methods can achieve dimming, they cannot adjust based on required energy consumption and real-time remaining energy, resulting in low energy efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a driving system and method for smart glass that can ensure the continuity and stability of driving and improve energy utilization.

[0005] To address the aforementioned technical problems, this invention provides a driving system for smart glass, comprising:

[0006] The dimming glass includes cholesteric liquid crystal glass, and the dimming glass has operating modes including full-color mode and glass mode;

[0007] The processor includes glass driving functionality for driving the dimming glass into different operating modes;

[0008] Driving the dimming glass into the full-color mode includes: converting the cholesteric liquid crystal glass from the P state to the FC state by combining real-time driving power consumption and current remaining power, or converting the cholesteric liquid crystal glass from the FC state to the P state by combining real-time driving power consumption and current remaining power.

[0009] Driving the dimming glass into the glass mode includes: converting the cholesteric liquid crystal glass from a P or FC state to an H state by combining real-time driving energy consumption and current remaining power, or converting the cholesteric liquid crystal glass from an H state to a P state, or converting the cholesteric liquid crystal glass from an H state to an FC state by combining real-time driving energy consumption and current remaining power.

[0010] In one embodiment of the present invention, the step of combining real-time driving power consumption and current remaining power to convert the cholesteric liquid crystal glass from the P state to the FC state includes:

[0011] Obtain the environmental data of the current state of the dimming glass and calculate the current power consumption required for driving based on this. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, use battery power supply; otherwise, use external power supply.

[0012] Set the driving parameters required to convert the cholesteric liquid crystal glass from the P state to the FC state: the first voltage HV1, the first frequency FQ1, and the first waveform logarithm PN1. Output a driving waveform according to the current driving parameters to make the cholesteric liquid crystal glass change its state.

[0013] In an embodiment of the present invention, the value range of the first voltage HV1 is 10V ≤ HV1 ≤ 60V, the value range of the first frequency FQ1 is 1Hz ≤ FQ1 ≤ 500Hz, and the value range of the first waveform logarithm PN1 is 1 ≤ PN1 ≤ 1000.

[0014] In an embodiment of the present invention, converting the cholesteric liquid crystal glass from the FC state to the P state by combining the real-time driving energy consumption and the current remaining power includes:

[0015] Obtain the environmental data of the current state of the dimming glass and calculate the current power consumption required for driving based on this. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, use battery power supply; otherwise, use external power supply.

[0016] Set the driving parameters required to convert the cholesteric liquid crystal glass from the FC state to the P state: the second voltage HV2, the second frequency FQ2, and the second waveform logarithm PN2, where HV2 < HV1; output a driving waveform according to the current driving parameters to make the cholesteric liquid crystal glass change its state.

[0017] In an embodiment of the present invention, the value range of the second frequency FQ2 is 100Hz ≤ FQ2 ≤ 20KHz, and the value range of the second waveform logarithm PN2 is PN2 ≥ 10.

[0018] In an embodiment of the present invention, converting the cholesteric liquid crystal glass from the P or FC state to the H state by combining the real-time driving energy consumption and the current remaining power requires continuous driving, including:

[0019] Step 1: Set the driving operation time t, the time interval n, and the driving parameters required to convert the cholesteric liquid crystal glass from the P or FC state to the H state: the third voltage HV3, the third frequency FQ3, where HV3 > HV1;

[0020] Step 2: Obtain the current environmental data of the dimming glass and calculate the power consumption required for the state transition operation time t. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, the battery power supply is used; otherwise, the external power supply is used. Continuously output the drive waveform for time t / n according to the current drive parameters.

[0021] Step 3: Determine whether a state transition is needed. If not, repeat step 2. If so, stop outputting the drive waveform and perform other state transitions.

[0022] In one embodiment of the present invention, the value range of the third frequency FQ3 is 1Hz≤FQ3≤500Hz.

[0023] In one embodiment of the present invention, the cholesteric liquid crystal glass is switched from the H state to the P state to stop the current driving waveform output and directly enter the termination process.

[0024] In one embodiment of the present invention, the step of combining real-time driving energy consumption and current remaining power to convert the cholesteric liquid crystal glass from the H state to the FC state includes:

[0025] Set the duration t5 for reducing the third voltage HV3 to 0V;

[0026] The current environmental data of the dimming glass is obtained and the power consumption required for the current drive is calculated in combination with the duration t5. The required power consumption is compared with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, the battery power supply is used; otherwise, the external power supply is used.

[0027] Keeping the third frequency FQ3 unchanged, the cholesteric liquid crystal glass is switched state by outputting a drive waveform that reduces the third voltage HV3 to 0V within time t5.

[0028] The present invention also provides a driving method for smart glass, comprising:

[0029] S1: Keep the processor in standby mode under the driving system of the smart glass. In standby mode, the processor continuously detects whether the dimming glass needs to switch working modes.

[0030] S2: Obtain the current environmental data of the dimming glass, identify the state transition that the cholesteric liquid crystal glass needs to perform when the dimming glass performs a working mode switch, and determine the type of state transition that the cholesteric liquid crystal glass needs to perform.

[0031] If the cholesteric liquid crystal glass needs to be converted from the P state to the FC state, from the FC state to the P state, or from the H state to the FC state, then execute S3; if the cholesteric liquid crystal glass needs to be converted from the H state to the P state, then execute S4; if the cholesteric liquid crystal glass needs to be converted from the P or FC state to the H state, then execute S5.

[0032] S3: Calculate the power consumption required for the corresponding state transition based on the current environmental data of the dimming glass, compare the required power consumption with the current remaining power of the power supply battery, if the required power consumption is less than the current remaining power, the battery power supply is used, otherwise the external power supply is used, the processor outputs the drive waveform according to the drive parameters required for different state transitions, and executes S1.

[0033] S4: The processor stops the output of the current driving waveform and executes S1;

[0034] S5: Set the processor's driver execution time t and time interval n;

[0035] S6: Calculate the power consumption required for the state transition to run for time t based on the current environmental data of the dimming glass. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, the battery is used for power supply. Otherwise, the external power supply is used. The processor continuously outputs the drive waveform for time t / n according to the drive parameters required for the state transition.

[0036] S7: The processor detects whether the dimming glass needs to switch its working mode. If so, it executes S2; if not, it reacquires the current environmental data of the dimming glass and executes S6.

[0037] The technical solution of the present invention has the following advantages compared with the prior art:

[0038] This invention divides the dimming glass into different working modes according to the application scenario. By combining real-time driving energy consumption and current remaining power, and by using driving waveforms to perform different state transitions on the cholesteric liquid crystal glass, the different working modes can be switched. While ensuring the continuity and stability of driving operation, energy utilization is effectively improved. Attached Figure Description

[0040] Figure 1 This describes the microstructure of the colored dimming glass in this invention.

[0041] Figure 2 This is a functional block diagram of the processor in this invention.

[0043] Figure 4 This is a flowchart illustrating the workflow steps of the method of the present invention. Detailed Implementation

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0045] Example 1

[0046] This invention discloses a driving system for smart glass, including dimming glass and a processor.

[0047] The dimming glass includes cholesteric liquid crystal glass, and the dimming glass has two working modes: full-color mode and glass mode. When the dimming glass is in the full-color mode, the cholesteric liquid crystal glass displays color as pixels. When the dimming glass is in the glass mode, the cholesteric liquid crystal glass adjusts its brightness according to the real-time light intensity.

[0048] like Figure 1 As shown, the cholesteric liquid crystal glass includes an upper glass substrate, a blue dimming film, a green dimming film, a red dimming film, and a lower glass substrate. The blue, green, and red dimming films are located between the upper and lower glass substrates, and are cholesteric liquid crystals. In this embodiment, the blue, green, and red dimming films are sequentially arranged between the upper and lower glass substrates, and their arrangement can be adjusted as needed.

[0049] like Figure 2 As shown, the processor includes a glass driving function for driving the dimming glass into different operating modes. Driving the dimming glass into the full-color mode includes: switching the cholesteric liquid crystal glass from a P state to an FC state based on real-time driving power consumption and current remaining power, or switching the cholesteric liquid crystal glass from an FC state to a P state based on real-time driving power consumption and current remaining power. Driving the dimming glass into the glass mode includes: switching the cholesteric liquid crystal glass from a P or FC state to an H state based on real-time driving power consumption and current remaining power, or switching the cholesteric liquid crystal glass from an H state to a P state, or switching the cholesteric liquid crystal glass from an H state to an FC state based on real-time driving power consumption and current remaining power.

[0050] Cholesteric liquid crystals possess three different molecular arrangements: a planar texture (P-state), a focal conic texture (FC-state), and a homeotropic texture (H-state). When a cholesteric liquid crystal is in the P-state, it exhibits Bragg reflection of light under certain conditions due to its helical structure. Bragg reflection refers to the periodic reflection of light at the interface between two different media. Applying a certain electric field to the P-state allows the cholesteric liquid crystal to transition to the FC-state. The FC-state is a multi-domain structure with a disordered helical distribution, but the helical structure within each domain still exists. The FC-state scatters incident light. Applying a sufficiently high voltage to the cholesteric liquid crystal transforms it into the transparent H-state. When the voltage in the H-state rapidly drops to zero, the cholesteric liquid crystal transitions to the P-state; when the voltage is gradually decreased, the H-state transitions to the FC-state. Both the P-state and the FC-state can exist stably under certain conditions. The reflection state in the P-state and the scattering state in the FC-state form a contrasting state.

[0051] The step of combining real-time driving energy consumption and current remaining power to convert the cholesteric liquid crystal glass from the P state to the FC state includes:

[0052] The system acquires the current environmental data of the dimming glass and calculates the power consumption required for the current drive. It compares the required power consumption with the remaining battery power. If the required power consumption is less than the remaining battery power, battery power is used; otherwise, external power is used. The system sets the driving parameters required to switch the cholesteric liquid crystal glass from the P-state to the FC-state: a first voltage HV1, a first frequency FQ1, and a first waveform logarithm PN1. The system outputs a driving waveform according to the current driving parameters to switch the cholesteric liquid crystal glass state. The waveform logarithm refers to the value after taking the logarithm of the waveform. The first voltage HV1 ranges from 10V to 60V, the first frequency FQ1 ranges from 1Hz to 500Hz, and the first waveform logarithm PN1 ranges from 1 to 1000.

[0053] The step of combining real-time driving energy consumption and current remaining power to convert the cholesteric liquid crystal glass from the FC state to the P state includes:

[0054] Obtain the environmental data of the current state of the dimming glass and calculate the power consumption required for the current drive accordingly. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, use battery power supply; otherwise, use external power supply. Set the drive parameters required to convert the cholesteric liquid crystal glass from the FC state to the P state: the second voltage HV2, the second frequency FQ2, and the second waveform logarithm PN2, where HV2 < HV1. Output the drive waveform according to the current drive parameters to make the cholesteric liquid crystal glass change its state. The value range of the second frequency FQ2 is 100 Hz ≤ FQ2 ≤ 20 KHz, and the value range of the second waveform logarithm PN2 is PN2 ≥ 10.

[0055] Combining the real-time drive energy consumption and the current remaining power to convert the cholesteric liquid crystal glass from the P or FC state to the H state requires continuous driving. Therefore, it includes:

[0056] Step 1: Set the drive running time t (usually 1 min ≤ t ≤ 60 min), the time interval n (usually 2 ≤ n ≤ 10), and the drive parameters required to convert the cholesteric liquid crystal glass from the P or FC state to the H state: the third voltage HV3, the third frequency FQ3, where HV3 > HV1, and the value range of the third frequency FQ3 is 1 Hz ≤ FQ3 ≤ 500 Hz;

[0057] Step 2: Obtain the environmental data of the current state of the dimming glass and calculate the required power consumption Py (P3) for the state transition operation for t time accordingly. Compare the required power consumption Py with the current remaining power Pb of the power supply battery. If the required power consumption is less than the current remaining power (i.e., Py < Pb), use battery power supply; otherwise (i.e., Py ≥ Pb), use external power supply, and continuously output the drive waveform for t / n time according to the current drive parameters;

[0058] Step 3: Determine whether a state transition is required. If not, re-execute Step 2; if so, stop outputting the drive waveform and perform the transition to other states.

[0059] Converting the cholesteric liquid crystal glass from the H state to the P state is to stop the output of the current drive waveform and directly enter the end process.

[0060] Combining the real-time drive energy consumption and the current remaining power to convert the cholesteric liquid crystal glass from the H state to the FC state includes:

[0061] Set the duration t5 for reducing the third voltage HV3 to 0V (typically 1s≤t5≤30s); acquire the current environmental data of the dimming glass and calculate the power consumption required for the current drive based on the duration t5; compare the required power consumption with the current remaining power of the power supply battery; if the required power consumption is less than the current remaining power, use battery power; otherwise, use external power supply; keep the third frequency FQ3 unchanged, and output the drive waveform according to reducing the third voltage HV3 to 0V within the time t5 to switch the state of the cholesteric liquid crystal glass.

[0062] In this embodiment, the environmental data includes temperature and humidity data, ambient light intensity data, and date and time data. The dimming glass also includes a solar panel, which is uniformly arranged around the cholesteric liquid crystal glass; when external power is required, power is supplied through the solar panel.

[0063] like Figure 3 The diagram shown is a general reference waveform used in this invention, where the upper electrode corresponds to the upper glass substrate and the lower electrode corresponds to the lower glass substrate.

[0064] Example 2

[0065] like Figure 4 As shown, the present invention also discloses a driving method for smart glass, comprising the following steps:

[0066] S1: Keep the processor in standby mode under the driving system of the smart glass in Embodiment 1. In standby mode, the processor continuously detects whether the dimming glass needs to switch working modes. If it needs to switch modes, execute S2. If it does not need to switch modes, keep the processor in standby mode.

[0067] S2: Obtain the current environmental data of the dimming glass, identify the state transition that the cholesteric liquid crystal glass needs to perform when the dimming glass performs a working mode switch, and determine the type of state transition that the cholesteric liquid crystal glass needs to perform.

[0068] If the cholesteric liquid crystal glass needs to be converted from the P state to the FC state, from the FC state to the P state, or from the H state to the FC state, then execute S3; if the cholesteric liquid crystal glass needs to be converted from the H state to the P state, then execute S4; if the cholesteric liquid crystal glass needs to be converted from the P or FC state to the H state, then execute S5.

[0069] In this embodiment, the power consumption required for the cholesteric liquid crystal glass to perform different state transitions is as follows: The power consumption required to transition from the P state to the FC state is P1. The power consumption required to transition from the FC state to the P state is P2. The power consumption required to transition from the P / FC state to the H state is P3. Since this state requires continuous driving, P3 here is related to the actual driving time. The power consumption required to transition from the H state to the P state is P4, which is usually approximately equal to 0. The power consumption required to transition from the H state to the FC state is P5.

[0070] S3: Calculate the required power consumption Px (P1, P2, or P5) for the corresponding state transition according to the environmental data of the current state of the dimming glass, compare the required power consumption with the current remaining power Pb of the power supply battery. If the required power consumption is less than the current remaining power, use battery power supply; otherwise, use external power supply. The processor outputs a driving waveform according to the driving parameters required for different state transitions and executes S1;

[0071] S4: The processor stops the output of the current driving waveform and executes S1;

[0072] S5: Set the driving running time t and time interval n of the processor;

[0073] S6: Calculate the required power consumption Py (P3) for the state transition to run for t time according to the environmental data of the current state of the dimming glass, compare the required power consumption Py with the current remaining power Pb of the power supply battery. If the required power consumption is less than the current remaining power (i.e., Py < Pb), use battery power supply; otherwise (i.e., Py ≥ Pb), use external power supply. The processor continuously outputs a driving waveform for t / n time according to the driving parameters required for this state transition;

[0074] S7: The processor detects whether the dimming glass needs to perform a working mode conversion. If so, execute S2; if not, re-obtain the environmental data of the current state of the dimming glass and execute S6.

[0075] In this embodiment, the driving experiment of the dimming glass is carried out using the method of the present invention. The specific driving parameters set are as follows:

[0076] The driving parameters required to transition from the P state to the FC state are HV1 = 32V / FQ1 = 10Hz / PN1 = 20;

[0077] The driving parameters required to transition from the FC state to the P state are HV2 = 24V / FQ2 = 1KHz / PN2 = 1000;

[0078] The driving parameters required to transition from the P / FC state to the H state are HV3 = 50V / FQ3 = 60Hz;

[0079] The driving condition required to transition from the H state to the P state is to stop the output of the original waveform;

[0080] The driving conditions required for the transition from H state to FC state are that the original 60Hz remains unchanged, and the voltage drops from 50V to 0V within a time t5 = 5s.

[0081] At room temperature of 25°C, the power consumption required for each state transition drive (P3 value is the power consumption evaluated based on a 10-minute drive) is shown in Table 1:

[0082] Table 1. Power Consumption Required for Each State Transition Driver

[0083]

[0084] Advantages of this invention compared to existing technologies:

[0085] 1. This invention divides the dimming glass into different working modes according to the application scenario. Combining real-time driving energy consumption and current remaining power, the cholesteric liquid crystal glass is subjected to different state transitions through driving waveforms to achieve switching between different working modes. While ensuring the continuity and stability of driving operation, it effectively improves energy utilization.

If the cholesteric liquid crystal glass needs to be converted from the P state to the FC state, from the FC state to the P state, or from the H state to the FC state, then execute S3; if the cholesteric liquid crystal glass needs to be converted from the H state to the P state, then execute S4; if the cholesteric liquid crystal glass needs to be converted from the P or FC state to the H state, then execute S5. S3: Calculate the power consumption required for the corresponding state transition based on the current environmental data of the dimming glass, compare the required power consumption with the current remaining power of the power supply battery, if the required power consumption is less than the current remaining power, the battery power supply is used, otherwise the external power supply is used, the processor outputs the drive waveform according to the drive parameters required for different state transitions, and executes S1. S4: The processor stops the output of the current driving waveform and executes S1; S5: Set the processor's driver execution time t and time interval n; S6: Calculate the power consumption required for the state transition to run for time t based on the current environmental data of the dimming glass. Compare the required power consumption with the current remaining power of the power supply battery. If the required power consumption is less than the current remaining power, the battery is used for power supply. Otherwise, the external power supply is used. The processor continuously outputs the drive waveform for time t / n according to the drive parameters required for the state transition. S7: The processor detects whether the dimming glass needs to switch its working mode. If so, it executes S2; if not, it reacquires the current environmental data of the dimming glass and executes S6.
