Patent Application
20220197101
The present disclosure is directed to systems that include non-light-emitting variable transmission devices, and more specifically to data collection for non-light-emitting variable transmission devices and methods of using the same.
A non-light-emitting variable transmission device can reduce glare and the amount of sunlight entering a room or passenger compartment. Conventionally, an electrochromic device can be at a particular transmission state. For example, the electrochromic device may be set to a certain tint level (i.e. a percentage of light transmission through the electrochromic device), such as full tint (e.g. 0% transmission level), full clear (e.g. 63%+/−10% transmission level).
As the electrochromic device continues to switch between tint and clear states, parameters that control the device too can change with use. For instance, variations in the voltages needed, the resistance within the device, or the power necessary to run multiple devices can change from a first point in time when the device is installed to months later when the device has been operational on a continuous basis. Knowing and understanding the changes can help optimize performance of the device. However, running diagnostics on the device can be costly, interrupt day to day operations of the device, and can inhibit the purpose of the device. As such, a need exists for a better control strategy for an electrochromic device.
Embodiments are illustrated by way of example and are not limited in the accompanying figures.
Skilled artisans appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the invention.
The following description in combination with the figures is provided to assist in understanding the teachings disclosed herein. The following discussion will focus on specific implementations and embodiments of the teachings. This focus is provided to assist in describing the teachings and should not be interpreted as a limitation on the scope or applicability of the teachings.
The terms “normal operation” and “normal operating state” refer to conditions under which an electrical component or device is designed to operate. The conditions may be obtained from a data sheet or other information regarding voltages, currents, capacitances, resistances, or other electrical parameters. Thus, normal operation does not include operating an electrical component or device well beyond its design limits.
The term “color rendering”, when referring to an electrical device, is intended to refer to the amount of light transmission permitted through an electrochromic window for a space to keep the color within the space within a wavelength of between 680 nm and 720 nm.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
The use of “a” or “an” is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural, or vice versa, unless it is clear that it is meant otherwise.
The use of the word “about”, “approximately”, or “substantially” is intended to mean that a value of a parameter is close to a stated value or position. However, minor differences may prevent the values or positions from being exactly as stated. Thus, differences of up to ten percent (10%) for the value are reasonable differences from the ideal goal of exactly as described.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The materials, methods, and examples are illustrative only and not intended to be limiting. To the extent not described herein, many details regarding specific materials and processing acts are conventional and may be found in textbooks and other sources within the glass, vapor deposition, and electrochromic arts.
A system can include one or more non-light-emitting, variable transmission devices; and a processor coupled and configured to provide control signals to the non-light-emitting, variable transmission devices.
The systems and methods are better understood after reading the specification in conjunction with the figures. System architectures are described and illustrated, followed by an exemplary construction of a non-light-emitting, variable transmission device, and a method of controlling the system. The embodiments described are illustrative and not meant to limit the scope of the present invention, as defined by the appended claims.
Referring to
The system 100 can be used to regulate the transmission of an insulated glazing unit (IGU) installed as part of architectural glass along a wall of a building or a skylight, or within a vehicle as well as to evaluate the performance of the one or more IGU's. As depicted, the system 100 can include a processor 110, a router 120, and a frame panel 150.
As illustrated in
As seen in
The system can be used with a wide variety of different types of non-light-emitting variable transmission devices, as described in more detail with respect to
In one embodiment, the processor can evaluate and log the types of data received from the one or more non-light emitting, variable transmission devices. In one embodiment, the processor 110 can evaluate the total message rate for the system. In one embodiment, the total message rate can include the amount of signals going to and coming from the one or more non-light-emitting, variable transmission devices that the system can handle. In one embodiment, the total message rate can include control signals to the one or more non-light emitting, variable transmission devices and performance signals from the one or more non-light emitting, variable transmission devices.
The processor 110 can then determine if a first request for data can be sent based on a threshold amount for sending requests, where the threshold amount is a percentage of the total message rate. In one embodiment, the total message rate is the maximum amount of messages that can be received and sent within a system. In one embodiment, the total message rate can be measured. In another embodiment, the total message rate can be calculated using a model. The first data can include performance information, such as voltage thresholds to switch the device from a clear state to a tint state, reflectance information, lighting and radiation information, information regarding one or more variable characteristics of glass, log information related to manual overrides. In one embodiment, the threshold amount can be set to 95% of the total message rate. For example, if the total message rate is 100 signals/minute, and the threshold amount is 95% then a current message rate of 90 signals/minute would be below the threshold amount. Thus, if the system, and in particular the current message rate, is below 95 signals/minute then a first request for data can be sent from the processor to the one or more non-light emitting, variable transmission devices. In another embodiment, the threshold amount can be set to 90% of the total message rate, such as 85% of the total message rate, or 80% of the total message rate, or 75% of the total message rate, or 70% of the total message rate, or 65% of the total message rate.
In another embodiment, and as seen in operation 204, the processor can send a first request to collect a first data from the one or more non-light emitting, variable transmission devices without first determining the current message rate. Instead, the processor can send a first request to collect a first data from the one or more non-light emitting, variable transmission devices. Then, as seen in operation 206, the processor can determine whether either the first data is received or a first-time out frame is reached. In such an embodiment, the system is self-limiting to ensure that the request for data collection does not interfere with the performance of the one or more devices. In one embodiment, the first-time out frame is 10 minutes, such as 8 minutes, or 5 minutes, or 3 minutes, or 1 minute. In one embodiment, if the first request for a first data set is sent after the current message rate is determined to be below the set threshold amount and the data is received, then a second request for a second data set can be sent. In another embodiment, if the first request for a first data set is sent after the current message rate is determined to be below the set threshold amount and the data is not received before the first time-out range is received, then the first data can be requeued and a second current message rate calculation can be performed to determine if the second current message rate is below the threshold amount. If the second current message rate is below the threshold amount, a second request for a second data set can be sent. If the second current message rate is above the threshold amount, the system does not send any more requests until the current message rate is below the threshold amount.
In one embodiment, if the first data is received without first determining the message rate and the threshold amount and before the first-time out frame is reached, then send a second request to collect a second data from the one or more non-light emitting, variable transmission devices is sent, as seen in operation 208. In a second embodiment, if the first-time out frame is reached before the first data is received, then the first request for the first data is requeued and a second request to collect a second data from the one or more non-light emitting, variable transmission devices is sent, as seen in operation 208. In another embodiment, if the first-time out frame is reached before the first data is received, then the first request for the first data is requeued and the current message rate can be determined. If the current message rate is below the threshold amount, a second request for a second data set can be sent. If the current message rate is above the threshold amount, the system does not send any more requests until the current message rate is below the threshold amount.
In another embodiment, the processor can send a first request to collect a first data from the one or more non-light emitting, variable transmission devices after first determining the message rate or threshold amount. In one embodiment, the threshold amount has not been reached and a first request is sent. The operations can proceed as seen above by then determine whether either the first data is received or a first-time out frame is reached and so on. In one embodiment, the processor can requeue a request until the request is fulfilled. For example, if a first request is not fulfilled, the processor can send a second request different from the first request and requeue the first request. If the second request is fulfilled, the processor can move on to an unfulfilled request, which may include the first request. The processor may continue until all requests are fulfilled. By requeing a request, the processor ensures that the priority is control of the non-light emitting, variable transmission devices and that requests for data do not adversely affect the performance of the devices. The data that is collected can subsequently be analyzed and used to adjust and control the performance of the one or more non-light-emitting, variable transmission devices.
