Description

Technical Field

[0001] The present invention relates to the technical field of edge computing gateways, and in particular to an edge computing gateway with intelligent scene linkage. Background Art

[0002] Traditional lighting control often relies on fixed switching modes or simple timing functions, which cannot meet users' needs for personalization and intelligence. With the advancement of Internet of Things technology, more and more smart devices are being integrated into home networks. How to achieve efficient control of lamps and their intelligent linkage with scenes has become an urgent problem to be solved. The edge computing gateway generally used for lamp management and control cannot determine whether the current lamp status is reasonable, such as keeping the lights on when no one is around or turning on strong lights during the day; it also does not have the function of predictive abnormality judgment. Therefore, the present invention provides an edge computing gateway with intelligent scene linkage, which predicts possible faults of the lighting system through historical data, and provides the function of scene-linked lamp status rationality judgment.

[0003] For example, the patent application with publication number CN112565451A discloses a DALI gateway and DALI lamp control system, which includes a power module, an MCU control module, a WIFI module, and a DALI conversion module; the MCU control module is connected to the DALI conversion module and the WIFI module respectively; the power module is connected to the DALI module, the MCU control unit, and the WIFI module respectively. The WIFI module is used to connect to an external control device via a WIFI network. The external control device sends control instructions to the DALI gateway to adjust the lamps. The external device is connected via the WIFI network to achieve wireless isolation. Even if a lamp controlled by a DALI gateway fails, it will not affect the other lines. The configuration is simple and flexible and is not restricted by the line. Secondly, most existing smart devices have WIFI functions. By connecting to the DALI gateway, users can control lamps through the WIFI network, enriching the use scenarios of the DALI system. However, this patent still has the problem raised by this background technology: it is impossible to determine whether the current lamp status is reasonable.

[0004] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person of ordinary skill in the art.

[0042] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0043] This embodiment introduces an edge computing gateway for intelligent scene linkage. Figure 1 The edge computing gateway includes a communication module, a status verification module, a fault prediction module, and a control module; wherein:

[0044] The communication module includes a first communication unit and a second communication unit; wherein the first communication unit is used to communicate with the lamp, sensor, and controller to collect scene data and lamp status data; the second communication unit is used to communicate with the Internet of Things platform;

[0045] The scene data includes space occupancy status, date tag, and time point; wherein the space occupancy status includes whether there is someone or not, which is determined based on a human body sensor; the date tag includes working day and non-working day;

[0046] The lamp status data includes switch status, light brightness, lamp temperature, real-time power consumption, usage time, and turn-on time; wherein, the switch status includes on and off; light brightness is collected by light sensors arranged around the lamp; lamp temperature is collected by temperature sensors arranged around the lamp; real-time power consumption is the real-time power consumption of the lamp; usage time is the cumulative time of the lamp from installation to the current moment; turn-on time refers to the cumulative time the lamp has been turned on this time.

[0047] The state verification module determines whether the lamp is in an abnormal state based on the scene data and the lamp state data; the abnormal state includes abnormal switch state and abnormal brightness;

[0048] The state verification module includes a first processing unit, a first state unit, and a second state unit;

[0049] The first processing unit is used to process the scene data and the lamp status data, including cleaning and standardizing the lamp status data, and encoding the scene data and the standardized lamp status data into feature vectors;

[0050] The first state unit is configured with a first state model for determining whether the lamp has an abnormal switch state. The first state model is a trained support vector machine whose input includes space occupancy status, date tag, time point, and switch state (these data are input into the support vector machine in the form of feature vectors), and whose output is a determination result of whether the lamp has an abnormal switch state. The state verification module is configured with a state verification strategy, specifically as follows: when the lamp has an abnormal switch state, the first state unit sends a first prediction instruction to the fault prediction module, which responds to the first prediction instruction and returns the probability of an electrical connection fault or a control circuit fault. The first state unit is configured with a first fault probability threshold. If the probability of an electrical connection fault or a control circuit fault is lower than the first fault probability threshold, a switch state abnormality prompt is sent to the IoT platform via the second communication unit. The IoT platform is responsible for interacting with the user. If the IoT platform returns information for adjusting the switch state, the first state unit sends a switch state adjustment control instruction to the control module. The control module responds to the control instruction and generates a control signal to adjust the switch state. If at least one of the probabilities of an electrical connection fault or a control circuit fault is not lower than the first fault probability threshold, a corresponding fault prompt is sent to the IoT platform via the second communication unit. The collaboration process between modules is as follows Figure 2 shown.

[0051] The second state unit is configured with a second state model for determining whether the lamp has abnormal brightness. The second state model is a trained support vector machine whose input includes the space occupancy status, date label, time point, and light brightness (these data are input into the support vector machine in the form of feature vectors), and the output is the determination result of whether the lamp has abnormal brightness.

[0052] The state verification strategy also includes: when there is abnormal brightness of the lamp, the second state unit sends a second prediction instruction to the fault prediction module, the fault prediction module responds to the second prediction instruction and returns the probability of lamp aging or light source failure; the second state unit is configured with a second fault probability threshold, if the probability of lamp aging or light source failure is lower than the second fault probability threshold, a brightness abnormality prompt is sent to the Internet of Things platform through the second communication unit; if the Internet of Things platform returns information for adjusting the brightness of the lamp, the second state unit sends a control instruction for adjusting the brightness of the lamp to the control module, the control module responds to the control instruction and generates a control signal to adjust the brightness of the lamp; if at least one of the probabilities of lamp aging and light source failure is not lower than the second fault probability threshold, a corresponding fault prompt is sent to the Internet of Things platform through the second communication unit.

[0053] Collect historical data, where any piece of historical data includes the scene data and the corresponding lamp status data; train the first state model and the second state model based on the historical data, and save the trained model parameters to a file; add labels of normal switch status and abnormal switch status to each piece of historical data used to train the first state model; add labels of normal brightness and abnormal brightness to each piece of historical data used to train the second state model; when the status verification module determines whether the lamp is in an abnormal state, load the model parameters from the file, and make an abnormal state judgment of the lamp based on the model parameters.

[0054] Support vector machines are machine learning algorithms particularly well-suited for high-dimensional data and small sample datasets. When determining abnormal switch status and brightness, support vector machines are well-suited to multidimensional features and exhibit good generalization capabilities. If a light is on when no one is using the space, this may indicate an abnormal state; if a light is off when someone is occupied, this may also indicate an abnormal state. Usage habits may vary on different days. For example, usage patterns differ significantly between weekdays and weekends. Lights may be used for extended periods on weekdays, but not on weekends. Usage habits and needs vary across time periods. For example, lights are typically unused late at night, so turning them on may indicate an anomaly. Furthermore, light brightness requirements vary depending on the occupancy status of the space, the day, and the time of day. By learning from historical data, support vector machines can accurately determine whether a light is in an abnormal state.

[0055] The fault prediction module performs fault prediction of the lamp based on the lamp status data;

[0056] The fault prediction module includes a second processing unit and a prediction model unit;

[0057] The second processing unit is used to process the lamp status data; the details are as follows:

[0058] Performing data cleaning on the lamp status data;

[0059] The brightness attenuation index is calculated based on the brightness of the light as follows:

[0060] Extract M consecutive cleaned data of light brightness and establish a time series of light brightness with a length of M, where M is a positive integer. Calculate the brightness attenuation index based on the time series of light brightness using the following formula:

[0061]

[0062] Where D represents the brightness attenuation index; b i The i-th element in the time series of the light brightness, i.e., the light brightness at the i-th time point; bi+1 Represents the i+1th element in the time series of the light brightness.

[0063] The luminance decay index reflects the degree of luminance decay over time. It is a standardized measure of luminance change, eliminating variations between individual luminaires. The luminance decay index of different luminaires can be directly compared, contributing to a unified standard. By tracking the changing trends of the luminance decay index, it is possible to more accurately determine whether a luminaire is aging.

[0064] The power consumption fluctuation index is calculated based on the real-time power consumption, and the method is as follows:

[0065] Extract N consecutive cleaned real-time power consumptions and establish a time series of real-time power consumption of length N, where N is a positive integer; perform n sliding interceptions on the time series of real-time power consumption using a time window of fixed length, and calculate the average of the real-time power consumption of the n sliding interceptions; let the length of the time window be m, then any sliding interception will obtain m consecutive real-time power consumptions; average the m consecutive real-time power consumptions to obtain the average of the real-time power consumption of this sliding interception; calculate the power consumption fluctuation index, using the following formula:

[0066]

[0067] Where F represents the power consumption fluctuation index; p j represents the mean value of real-time power consumption captured by the jth sliding operation; p k The kth element in the time series representing the real-time power consumption, that is, the real-time power consumption at the kth time point;

[0068] The Power Fluctuation Index reflects the degree of fluctuation in a luminaire's power consumption relative to its average power consumption. This allows for more sensitive detection of abnormal power consumption fluctuations, and thus, more sensitive identification of electrical connection issues. Furthermore, the Power Fluctuation Index is a standardized measure of power consumption variation, eliminating variations between individual luminaires.

[0069] Encode the lamp temperature, usage time, on time, brightness decay index, and power consumption fluctuation index into a feature vector;

[0070] The prediction model unit is configured with a fault prediction model for predicting lamp faults; the output of the fault prediction model is the probability of occurrence of each type of fault in the lamp, and the fault types include electrical connection fault, control circuit fault, lamp aging, light source fault, and lamp overheating;

[0071] Causes of electrical connection failure include poor contact of wires, loose plugs, etc., which may cause the lamp to shut down abnormally and consume too much energy. It is necessary to check and tighten the connection terminals or replace the connection wires; control circuit failure is caused by failure of relays or switching elements in the control circuit, which may cause the lamp to fail to shut down normally. Users need to check and replace relays or switching elements; lamp aging is due to the cumulative use time of the lamp being too long. As the opening time increases, the brightness of the light will gradually decrease; light source failure can also cause abnormal light brightness; due to long opening time, poor heat dissipation, ambient temperature and other reasons, by monitoring the temperature around the lamp, it is possible to predict whether the lamp is at risk of overheating.

[0072] The input of the fault prediction model includes the characteristic vector of the lamp temperature, usage time, opening time, brightness attenuation index, and power consumption fluctuation index; the fault prediction model is a multi-layer perceptron, referring to Figure 3 , including an input layer, a hidden layer, and an output layer; wherein the input layer is used to receive the characteristic vectors of lamp temperature, usage time, on time, brightness decay index, and power consumption fluctuation index as input variables; the hidden layer is used to extract the characteristics of the input variables; and the output layer calculates and outputs the probability of each fault type based on the characteristics of the input variables. Multilayer perceptrons can capture nonlinear relationships in data and are suitable for lamp fault prediction, because the occurrence of faults is often not a simple linear relationship. Multilayer perceptrons can process high-dimensional data and are suitable for multiple feature inputs. They are suitable for the fault prediction task of the present invention, processing multiple input features and simultaneously outputting the probabilities of multiple faults.

[0073] The fault prediction module is configured with a prediction assistance strategy, specifically as follows: the input of the multi-layer perceptron also includes a lamp status code; the lamp status code includes a switch status abnormality code and a brightness abnormality code; the fault prediction module performs lamp fault predictions at a fixed period and sends the probability of each fault to the IoT platform via the second communication unit, wherein the switch status abnormality code and the brightness abnormality code are both set to 0; if the fault prediction module receives the first prediction instruction, the switch status abnormality code is set to 1; if the fault prediction module receives the second prediction instruction, the brightness abnormality code is set to 1. Based on the prediction assistance strategy, when the lamp is in an abnormal situation that does not match the scene, a more targeted fault prediction can be made based on the specific abnormal situation, thereby improving the accuracy of the fault prediction.

[0074] The control module is used to generate a control signal, and the control signal is used to control the state of the lamp.

[0075] The control module includes an instruction parsing unit and a control signal unit;

[0076] The instruction parsing unit is used to parse the control instruction and obtain the adjustment amount of the lamp state; the control signal unit generates a control signal based on the adjustment amount of the lamp state.

[0077] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the purpose and scope of protection of the present invention, which are all protected by the present invention.
