[0001] This invention relates to the field of intelligent glass curtain walls, and in particular to an intelligent glass curtain wall system. Background Technology

[0002] A glass curtain wall is a building exterior or decorative structure composed of glass and a load-bearing system that does not share the load of the main structure. It serves multiple functions, including reflection, heat resistance, and visibility. Glass curtain walls typically have single-layer or double-layer glass structures.

[0003] In existing technologies, glass curtain walls are mainly implemented using glass technologies such as polymer dispersed liquid crystal (PDLC), suspended particle dimming (SPD), and electrochromism (EC). However, these existing glass curtain walls typically cannot be functionally converted for different application scenarios and lack dimming capabilities; furthermore, the display functions of glass curtain walls are usually only implemented within a small area and cannot be uniformly managed across a large number of building curtain walls. Summary of the Invention

[0011] In one embodiment of the present invention, the glass node comprises cholesteric liquid crystal glass.

[0012] 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 dimming film, green dimming film, and red dimming film are located between the upper glass substrate and the lower glass substrate, and the blue dimming film, green dimming film, and red dimming film are cholesteric liquid crystals.

[0013] In one embodiment of the present invention, the building processing unit includes a building processor, the functions of which include:

[0014] Cloud platform integration enables the building processor and the cloud platform to interact with each other;

[0015] Control information processing: The control information sent from the cloud platform is processed and then transmitted to the block processing unit.

[0016] Image information processing adapts the target display image of the glass curtain wall to all glass nodes in the current building and decomposes them to obtain the target display state of each glass node, and transmits the control information of the target display state to each block processing unit;

[0020] In one embodiment of the present invention, the block processing unit includes a block processor, the block processor having the following functions:

[0021] Solar-powered control, using solar energy to power the glass nodes;

[0050] 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.

[0051] Reference Figure 1As shown, this invention discloses an intelligent glass curtain wall system, including at least one building module and a cloud platform. The building module includes glass nodes, and the glass nodes have two operating modes: full-color mode and glass mode. The cloud platform is connected to the building module and manages the operating modes of the glass nodes through the building module. The cloud platform connects to all building modules wirelessly or via wired connection, achieving unified management of all glass nodes under the building module. The system is simple to operate and control, easy to maintain, and can be widely used in industries such as intelligent buildings.

[0052] When the glass nodes are in the full-color mode, each glass node displays color as a pixel. Specifically, the blue, green, and red dimming films are controlled to be in either the P-state or FC-state. In this state, each glass node is a pixel, displaying color under side lighting. This mode is primarily used for displaying images at night. The glass nodes themselves do not emit light; however, the colors switched by the RGB dimming films can be seen under side lighting at night. The side lighting is typically white light.

[0053] When the glass nodes are in the specified glass mode, each node transforms into a dimming glass, adjusting its brightness according to real-time light intensity. Specifically, the blue, green, and red dimming films are controlled to be in either the FC (Flash-Couple) or H (H) state. In this state, each glass node functions as a dimming glass, eliminating the need for a side light source. In the H state, the glass nodes are transparent, allowing light to enter the room; in the FC state, they are in a scattering state, providing privacy protection and infrared radiation protection. This mode is primarily used during the day as smart glass.

[0054] 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.

[0055] When the cloud platform manages the working mode of the glass node through the building module, the management modes used include: single-point mode, multi-point mode, and central control mode.

[0056] Single-point mode: control is performed on a single glass node, which can be operated by remote control or other means.

[0057] Multi-point mode: Control multiple glass nodes in the same scene (such as an office), which can be operated by remote control or other means.

[0058] The master control mode is used to control all glass nodes under at least one building module, mainly by operating the status of all glass nodes through the cloud platform.

[0059] like Figure 2 As shown, the building module includes a building processing unit and at least one block processing module. The block processing module includes a block processing unit and at least one glass node. The block processing unit is connected to the glass node and controls the operation of the glass node; the building processing unit is connected to the block processing unit and controls the operating mode of the glass node through the block processing unit.

[0060] In this embodiment, each building module corresponds to a building with a glass curtain wall. Each building consists of one building processing unit and x block processing modules. Each block processing module consists of one block processing unit and multiple glass nodes. The glass nodes in the block processing module are denoted by Nij, where subscript i indicates the floor of the building in which the glass node is located within the actual glass curtain wall, and subscript j indicates the building in which the glass node is located within the actual glass curtain wall. In this embodiment, the glass nodes of the first floor are N11, N12, ..., N1a; the glass nodes of the second floor are N21, N22, ..., N2b; and the glass nodes of the h-th floor are Nh1, Nh2, ..., Nhg. Each glass node in each floor is set as needed and may or may not be present. The block processing unit is denoted by HBk, where subscript k indicates the building in which the block processing unit is located within the actual glass curtain wall. In this embodiment, the block processing units are HB1~HBx, and the total number is x = max{a, b, ..., g}. Each block processing unit controls the state of a row of nodes. Taking HB1 as an example, it can control the state of nodes N11 to Nh1.

[0061] In this embodiment, the glass node includes cholesteric liquid crystal glass and multiple solar modules. 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 dimming film, green dimming film, and red dimming film are located between the upper and lower glass substrates. The blue dimming film, green dimming film, and red dimming film are cholesteric liquid crystals. Figure 7 As shown, in this embodiment, the blue, green, and red dimming films are sequentially arranged between the upper and lower glass substrates. The arrangement order of the blue, green, and red dimming films can be adjusted as needed. The solar energy modules are uniformly distributed around the cholesteric liquid crystal glass to provide operating energy to the cholesteric liquid crystal glass. Figure 3 As shown, in this embodiment, each cholesteric liquid crystal glass has a solar module distributed around its perimeter. Taking node N11 as an example, there are four solar modules S111~S114 around its perimeter.

[0062] In this embodiment, the building processing unit includes a building processor, such as... Figure 4 As shown, the building processor's functions include cloud platform integration, control information processing, image information processing, and block processing unit control.

[0063] The cloud platform integration involves enabling the building processor and the cloud platform to interact via wired or wireless means. In this embodiment, the building processor interacts with the cloud platform via Ethernet, WiFi, 5G, or other means.

[0064] The control information processing involves processing the control information sent from the cloud platform and then transmitting it to the block processing unit; the control information includes synchronization timestamps, light source drivers, glass drivers, etc.

[0065] Image information processing involves adapting the target display image of the glass curtain wall to all glass nodes in the current building and decomposing it to obtain the target display state of each glass node. The control information of the target display state is then transmitted to each block processing unit. The adaptation method involves decomposing the target display image into pixels corresponding to the glass curtain wall, and using the extracted R / G / B color grayscale of each pixel as the target display state of each glass node.

[0066] The block processing unit control is to control the block processor in the block processing unit to work.

[0067] In this embodiment, the block processing unit includes a block processor, such as... Figure 5 As shown, the functions of the block processor include: solar energy control, power input / output control, and mounted node control.

[0068] Solar control involves controlling the operation of the solar module to power the glass node using solar energy.

[0069] The power input and output control is as follows: when the solar power is insufficient, an external power source is used to power the glass node; the power supply prioritizes the solar module, and the external power source is used only when the solar power is insufficient, with the power output provided to the node for backup.

[0070] The mounting node control involves enabling the block processor and the building processor in the building processing unit to interact via wired or wireless means, obtaining control information, and then distributing it to each mounted glass node. In this embodiment, the block processor interacts with the building processor via Ethernet, WiFi, 5G, or other methods.

[0071] In this embodiment, the glass node includes a node driver, such as... Figure 6 As shown, the functions of the node driver include: power input control, solar energy control, communication protocol control, light source driving, glass driving, and synchronization timestamp control.

[0072] The power input control is as follows: select an external power supply based on the actual power demand of the glass node;

[0073] Solar power control involves selecting solar power supply based on the actual power demand of the glass nodes.

[0074] The communication protocol control is as follows: a suitable low-power protocol is selected to enable the node driver and the block processor in the block processing unit of the building module to interact with each other; the low-power protocol used in this embodiment is a long-distance low-power protocol such as LoRa, so that the block processor is in a constant transmitting state and the node driver is in a constant receiving state, thereby saving power consumption.

[0075] The light source is driven by controlling the glass node to enter the full-color mode;

[0076] The glass driver is: to control the glass node to enter the glass mode.

[0077] Synchronization timestamp control works as follows: When processing image information, the building processor in the building module sets the timestamp information for each glass node, packages it, and then transmits it to each glass node through the processor in the block processing unit; the glass nodes synchronize according to the received timestamp information, so that the switching pace of all nodes is kept consistent, which can create a dynamic change effect.

[0078] Advantages of this invention compared to existing technologies:

[0079] This invention utilizes glass technology based on a three-layer superposition of CLC (Cholesteric-Liquid-Crystal) and RGB layers. By setting two different operating modes for the glass nodes—full-color mode and glass mode—it can display color images in full-color mode and function as smart dimming glass in glass mode. It combines the functions of color image display and smart dimming glass, offering features such as privacy protection and infrared radiation protection. Furthermore, by managing the operating status of all glass nodes under all building modules through a cloud platform, it enables unified management of large-scale, cross-building curtain walls, making it widely applicable.
