Description

Technical Field

[0001] This application relates to the field of emergency equipment technology, and in particular to an eyewash station control method, device, equipment and storage medium. Background Technology

[0002] Eyewash stations are emergency protective devices used in laboratories, factories, medical institutions, and other similar locations. They are primarily used to quickly and urgently rinse the eyes when personnel come into contact with harmful substances such as corrosive chemicals or pollutants. They are key emergency equipment for preventing chemical injuries to the eyes of workers and ensuring workplace safety.

[0003] Currently, most eyewash stations use standardized water flow parameters to rinse users' eyes. However, in actual emergency situations, different users have varying degrees of eye contamination and tolerance to water flow, resulting in inconsistent cleaning effectiveness of the standardized eyewash method in some cases.

[0004] Therefore, how to improve the eye rinsing effect of eyewash stations for different users is an urgent problem to be solved. Summary of the Invention

[0005] The main objective of this application is to provide an eyewash station control method, device, equipment, and storage medium, which aims to improve the eyewash station's eye rinsing effect for different users.

[0006] To achieve the above objectives, this application provides an eyewash station control method, the eyewash station control method comprising: During the eye rinsing process, the eye opening and closing degree and pupillary response parameters of the subject are monitored. Based on the eye opening and closing degree and the pupil response parameters, the water flow parameters are dynamically determined; The object to be rinsed is rinsed with water according to the water flow parameters.

[0007] In one embodiment, the step of monitoring the eye opening and pupillary response parameters of the object being rinsed includes: Obtain a facial image of the object being rinsed; Perform eye key point detection on the facial image and extract the feature point set of the eye region; The eye opening degree is determined based on the relative distance between the upper and lower eyelids in the feature point set; The pupil response parameters are determined based on the displacement and / or area change of the pupil size relative to the initial pupil size in the feature point set, wherein the initial pupil size is the pupil size of the subject being rinsed collected before the start of the current eye rinsing, or the historical pupil size of the subject being rinsed.

[0008] In one embodiment, the step of dynamically determining the water flow parameters based on the eye opening and closing degree and the pupillary response parameters includes: The current stage of the rinsing process is obtained, and the preset reference water flow parameters corresponding to the stage are determined. The stage is one of the following in chronological order: a rapid rinsing stage, a gentle rinsing stage, and a soothing massage stage. The water flow parameters are determined based on the eye opening and closing degree and the pupil response parameters, with the preset benchmark water flow parameters as the upper limit.

[0009] In one embodiment, the step of determining the water flow parameters based on the eye opening and closing degree and the pupillary response parameters includes: Based on the eye opening and closing degree, the water flow rate within the current control cycle is determined; Based on the pupil response parameters, the water flow intensity within the current control cycle is determined; The water flow rate and the water flow intensity are used as the water flow parameters.

[0010] In one embodiment, the step of determining the water flow rate within the current control cycle based on the eye opening degree includes: Determine the frequency of eye opening and closing between open and closed eyes within a preset time period prior to the current moment; When the switching frequency is greater than the preset frequency, the water flow rate in the current control cycle is determined according to the switching frequency, wherein the switching frequency is negatively correlated with the water flow rate; When the switching frequency is less than or equal to the preset frequency, the water flow rate within the current control cycle is determined based on the eye opening and closing degree, wherein the eye opening and closing degree and the water flow rate are positively correlated.

[0011] In one embodiment, the step of determining the water flow intensity within the current control cycle based on the pupil response parameters includes: The pain stress level of the subject being rinsed is determined based on the pupillary response parameters. The water flow intensity within the current control period is determined based on the pain stress level, wherein the pain stress level and the water flow intensity are negatively correlated.

[0012] In one embodiment, the method further includes: During the process of rinsing the eyes of the object being rinsed, a monitoring image of the object being rinsed is acquired; The posture and / or movement trajectory of the object being rinsed are identified based on the monitoring images; When the posture is detected as a falling posture, the movement trajectory meets a preset static timeout condition, or the movement trajectory meets a preset violent struggle condition, a safety response operation is executed, wherein the safety response operation includes at least one of pausing flushing, reducing water flow intensity, and issuing an alarm signal.

[0013] Furthermore, to achieve the above objectives, this application also provides an eyewash station control device, the eyewash station control device comprising: The monitoring module is used to monitor the eye opening and closing degree and pupil response parameters of the object being rinsed during the process of rinsing the eyes. The determination module is used to dynamically determine the water flow parameters based on the eye opening and closing degree and the pupil response parameters; The rinsing module is used to rinse the eyes of the object being rinsed according to the water flow parameters.

[0014] In addition, to achieve the above objectives, this application also proposes an eyewash station, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the eyewash station control method described above.

[0015] In addition, to achieve the above objectives, this application also provides a storage medium, which is a computer-readable storage medium, on which a program implementing an eyewash station control method is stored, and the program implementing the eyewash station control method is executed by a processor to implement the steps of the eyewash station control method as described above.

[0016] In addition, to achieve the above objectives, this application also provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the eyewash station control method described above.

[0017] This application provides an eyewash station control method. During the process of rinsing the eyes of the subject, the method monitors the eye opening and closing degree and pupil response parameters of the subject. Then, based on the monitored eye opening and closing degree and pupil response parameters, the method dynamically determines the water flow parameters. Finally, the method rinses the subject's eyes according to the dynamically determined water flow parameters.

[0018] In summary, this application, by monitoring the eye opening and closing degree and pupillary response parameters of the subject in real time during eye irrigation and dynamically determining water flow parameters based on these two physiological feedback indicators, enables the eyewash station to adaptively match individual differences among users in terms of contamination levels, pain sensitivity, and stress responses. This allows for more intense or longer-lasting effective irrigation for users with heavier contamination or higher tolerance, while ensuring irrigation safety. Simultaneously, it automatically reduces water flow stimulation for users with lighter contamination or lower tolerance to avoid secondary injury. This improves the eye cleaning effect and irrigation comfort for different individuals, overcoming the problem of incomplete irrigation or over-stimulation for some users caused by a "one-size-fits-all" approach under fixed parameter modes. Therefore, it enhances the adaptability and irrigation efficiency of the eyewash station in complex emergency scenarios. Attached Figure Description

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0025] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Currently, most eyewash stations use standardized water flow parameters to rinse users' eyes. However, in actual emergency situations, different users have varying degrees of eye contamination and tolerance to water flow, resulting in inconsistent cleaning effectiveness of the standardized eyewash method in some cases.

[0027] Therefore, how to improve the eye rinsing effect of eyewash stations for different users is an urgent problem to be solved.

[0028] The main solution of this application is: during the process of rinsing the eyes of the object being rinsed, monitoring the eye opening and closing degree and pupil response parameters of the object being rinsed; dynamically determining the water flow parameters based on the eye opening and closing degree and pupil response parameters; and rinsing the eyes of the object being rinsed according to the water flow parameters.

[0029] This application monitors the eye opening and closing degree and pupil response parameters of the subject in real time during eye rinsing, and dynamically determines the water flow parameters based on these two physiological feedback indicators. This allows the eyewash station to adaptively match individual differences among users in terms of contamination level, pain sensitivity, and stress response. Thus, while ensuring rinsing safety, it provides more intense or longer-lasting effective rinsing for users with heavier contamination or higher tolerance. Simultaneously, it automatically reduces water flow stimulation for users with lighter contamination or lower tolerance to avoid secondary injury. This improves the eye cleaning effect and rinsing comfort for different individuals, overcoming the problem of incomplete rinsing or excessive stimulation for some users caused by a "one-size-fits-all" approach under fixed parameter modes. Therefore, it enhances the adaptability and rinsing efficiency of the eyewash station in complex emergency scenarios.

[0030] It should be noted that the execution subject of the method in the various embodiments of the eyewash station control method of this application can be an eyewash station control system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, personal computer, mobile phone, etc., or an eyewash station capable of realizing the above functions, etc. This embodiment does not specifically limit it. The following uses the eyewash station control system (i.e., controller) as the execution subject as an example to describe this embodiment and the following embodiments.

[0031] Based on this, this application proposes a first embodiment of an eyewash station control method, please refer to... Figure 1The eyewash station control method includes steps S10 to S30: Step S10: During the process of rinsing the eyes of the subject, monitor the eye opening and closing degree and pupil response parameters of the subject.

[0032] Eye opening / closing refers to the quantitative representation of the relative distance or degree of opening between the user's upper and lower eyelids. It reflects the user's eyelid closure state, specifically manifested as open, half-open, or closed eyes, or their continuous variations. Pupil response parameters are the quantitative representation of the dynamic changes in the user's pupils relative to a baseline state during rinsing. They reflect the physiological response of the pupils to water flow stimulation or pain stress, specifically manifested as changes in pupil size, such as contraction or dilation. Monitoring refers to the repeated acquisition, updating, and output of eye opening / closing and pupil response parameters at a preset sampling frequency throughout the rinsing process.

[0033] Throughout the entire process of the eyewash station starting to rinse and the water flow acting on the user's eyes, the controller continuously collects image signals of the user's facial area through a visual sensor and processes the image signals in real time. It extracts the relative distance between the upper and lower eyelids as the eye opening and closing degree, and at the same time extracts the position or area information of the pupil boundary and calculates its change relative to the baseline state as the pupil response parameter. This monitoring step is not executed once, but is continuously repeated during the rinsing process to ensure that the controller can capture any dynamic changes in the eye state over time.

[0034] In this embodiment, step S10 may include: Step S101: Obtain a facial image of the object being rinsed; Step S102: Perform eye key point detection on the facial image and extract the feature point set of the eye region.

[0035] A facial image refers to the digital image data output by a visual sensor after imaging the facial area of ​​a subject being washed. It contains at least effective pixel information capable of identifying the eye region and extracting eye features, serving as the raw data source for subsequent eye keypoint detection and pupil parameter extraction. Eye keypoint detection refers to the process of locating and marking anatomically significant feature positions (such as the inner and outer corners of the eyes, the upper eyelid margin, the lower eyelid margin, and the pupil center) in a facial image using a pre-defined image processing algorithm or machine learning model. The feature point set refers to the set of two-dimensional coordinate points output by the eye keypoint detection algorithm, representing the positions of various key features in the eye region, which are used for subsequent calculations of eye opening and closing and pupil parameter extraction.

[0036] During the rinsing process, the controller controls the vision sensor to image the facial area of ​​the object being rinsed at a preset acquisition frequency, acquiring a digital image containing facial features. Subsequently, the controller inputs the facial image into a pre-trained eye key point detection model. This model analyzes the facial image using algorithms such as convolutional neural networks, locating the key feature points of the left and right eye regions within the face area, including the upper eyelid key point, lower eyelid key point, inner corner of the eye, outer corner of the eye, and the center point or boundary point of the pupil. The two-dimensional coordinates of each key point together constitute the feature point set of the eye region.

[0037] Step S103: Determine the eye opening degree based on the relative distance between the upper and lower eyelids in the feature point set.

[0038] Relative distance refers to the vertical distance or its representation value between the upper and lower eyelid feature points in the feature point set, which is used to quantitatively reflect the degree of eyelid opening. Eye opening degree refers to a quantitative value determined based on the relative distance between the upper and lower eyelids, used to characterize the user's current eyelid opening degree. Its specific form can be a continuous value, or it can be a discrete state level such as open eye, half-open eye, and closed eye, which is divided by comparing with a preset threshold.

[0039] The controller locates feature points in the upper eyelid region and the lower eyelid region from the feature point set, calculates the vertical distance or Euclidean distance between them, and uses this distance value as a quantitative representation of the eye opening degree.

[0040] Step S104: Determine the pupil response parameters based on the displacement and / or area change of the pupil size relative to the initial pupil size in the feature point set, wherein the initial pupil size is the pupil size of the object being rinsed collected before the start of the current eye rinsing, or the historical pupil size of the object being rinsed.

[0041] Pupil size refers to the quantitative value representing the size of the pupil from a set of feature points; its specific form can be the radius, diameter, or area of ​​the pupil. Displacement change refers to the amount by which the pupil's center position shifts relative to its initial position during rinsing. Area change refers to the amount by which the pupil's area changes relative to its initial area during rinsing; it reflects the pupil's constriction or dilation response. Initial pupil size refers to the pupil size value used as a benchmark for comparing pupil changes; it can be the pupil size acquired in real-time before the start of the current eye rinsing session, or it can be a historical pupil size of the subject pre-stored in a storage medium. Pupil response parameters are quantitative values ​​determined based on the change in pupil size relative to the initial pupil size, used to characterize the degree of physiological response of the pupil to rinsing stimuli or pain stress.

[0042] The controller extracts pupil boundary feature points or pupil center and radius information from the feature point set to determine the current pupil size; then it obtains the initial pupil size; the controller calculates the displacement change (shift in pupil center position) and / or area change (contraction or dilation of pupil area) of the current pupil size relative to the initial pupil size, and outputs this change as a pupil response parameter. It should be understood that the larger the value of this pupil response parameter, the more significant the physiological response of the pupil, i.e., the higher the user's pain stress level.

[0043] Step S20: Dynamically determine water flow parameters based on the eye opening and closing degree and the pupil response parameters.

[0044] Water flow parameters refer to the set of control variables characterizing the flushing water flow, including at least water flow rate and / or water flow intensity. Water flow rate controls the amount of water passing through the nozzle assembly per unit time, while water flow intensity controls the impact force or velocity of the water flow. Dynamic determination means that the water flow parameters are not set once before flushing begins and remain unchanged, but rather are continuously updated and adjusted according to preset control logic based on real-time feedback from eye opening and closing and pupillary response parameters during the flushing process.

[0045] After acquiring the current eye opening and pupil response parameters from the monitoring steps within each control cycle, the controller processes them according to the preset control logic: It determines the water flow rate based on the current eye opening value; for example, a larger water flow rate is determined when the eye opening is large (eyes open), and a smaller water flow rate or zero is determined when the eye opening is small (eyes closed or half-open). It also determines the water flow intensity level based on the change in the pupil response parameters and the direction of change; for example, a lower water flow intensity is determined when the pupil response parameters indicate a high level of pain stress, and a higher water flow intensity is determined when the stress level is low. Finally, it combines the water flow rate and water flow intensity into the water flow parameters for the current control cycle and outputs them to subsequent execution steps.

[0046] Step S30: Rinse the eyes of the object being rinsed according to the water flow parameters.

[0047] The controller acquires the water flow parameters output during the current control cycle, converts these parameters into drive signals that can be recognized by the various actuators in the water supply pipeline (such as solenoid valves, flow regulating valves, pressure regulators, etc.), and sends drive commands to the corresponding actuators so that these actuators can work together according to the water flow rate and water flow intensity specified in the water flow parameters, thereby generating a water flow with target characteristics at the nozzle assembly outlet and continuously acting on the user's eyes.

[0048] In one feasible implementation, before rinsing the eyes of the person being rinsed, the position of the eyewash nozzle assembly is adjusted based on the user's eye position and interpupillary distance to ensure the nozzle is aimed at the user's eyes. Specifically, as... Figure 2 The diagram shows the structure of an eyewash station (due to its symmetrical structure, only one side is shown). The eyewash station includes a wall-mounted base 01, a horizontal rotation mechanism 02, a pitch adjustment mechanism 03, an interpupillary distance adjustment mechanism 04, a nozzle assembly 05, and a sensor module 06 (including a microwave radar sensor, a millimeter-wave radar sensor, and a vision sensor). The horizontal rotation mechanism, mounted on the wall-mounted base, includes a horizontal turntable driven by a first motor, which continuously rotates the nozzle assembly in the horizontal plane to match the user's horizontal azimuth angle. The pitch adjustment mechanism is linked to and supported by the horizontal rotation mechanism, and includes a pitch shaft driven by a second motor, which moves the nozzle assembly in the vertical plane to match the user's vertical elevation angle. The rotation of the horizontal rotation mechanism causes the pitch adjustment mechanism and its supported components to rotate together in the horizontal plane, achieving coordinated movement in both the horizontal azimuth and vertical elevation angles. The interpupillary distance adjustment mechanism is located at the end of the pitch adjustment mechanism and serves as the final stage of the adjustment chain, including a horizontal adjustment component driven by a third motor. This system is used to adjust the relative distance between the two nozzles in the horizontal direction to match the user's interpupillary distance. This ensures that while the overall position of the nozzle assembly is aligned with the eye position, the water outlet distance between the two nozzles is also adapted to the user's individual structural parameters. The first motor of the horizontal rotation mechanism and the second motor of the pitch adjustment mechanism both adopt a hollow shaft structure, with the water supply hose passing through the inside of each hollow shaft to ensure that the pipeline is not twisted or tangled during multi-axis coordinated movement. The controller calculates the three-dimensional coordinates of the eye position into horizontal rotation angle, pitch angle, and interpupillary distance adjustment values, and drives the horizontal rotation mechanism, pitch adjustment mechanism, and interpupillary distance adjustment mechanism to move in coordination, so that the water outlet direction and the point of water flow of the nozzle assembly are precisely aligned with the center of the user's eyes, while the distance between the two nozzles matches the user's interpupillary distance.

[0049] The nozzle assembly adopts a constant flow buffer nozzle structure, which is installed at the end of the multi-axis adjustment mechanism. It is used to convert the water flow delivered by the water supply pipeline into a gentle laminar water curtain that meets safety standards and is then output to the user's eyes. The constant flow buffer nozzle has a flow stabilization structure inside, which can maintain the stability of the water flow and flow pattern when the external water pressure fluctuates, and avoid the drastic change in water flow impact force caused by water pressure fluctuations. At the same time, the constant flow buffer nozzle can be configured with a single nozzle or a double nozzle structure to adapt to the water output requirements of different flushing modes.

[0050] Furthermore, a digital pressure transmitter is integrated at the water inlet pipe. This digital pressure transmitter is electrically connected to the controller and is used to collect water pressure data in the water inlet pipe in real time and transmit the water pressure signal to the controller. After receiving the water pressure signal, the controller compares it with a preset safe pressure threshold. When the water pressure is lower or higher than the safe threshold, the controller determines that the water supply pressure is abnormal and stops the flushing operation and / or issues an alarm signal to avoid poor flushing effect due to insufficient water pressure or secondary damage to the user's eyes due to excessive water pressure.

[0051] A fast-opening and closing solenoid valve is installed in the water supply pipeline. This solenoid valve is electrically connected to the controller and is directly controlled by the controller. It responds to the control signal output by the controller to realize the millisecond-level opening and closing operation of the water flow. When the controller determines that flushing needs to start, it outputs an opening signal to the solenoid valve. The solenoid valve completes the opening action within a few milliseconds, allowing the water flow to quickly reach the nozzle assembly. When the controller determines that flushing needs to be paused or terminated, it outputs a closing signal to the solenoid valve. The solenoid valve completes the closing action within a few milliseconds, realizing the rapid cutoff of the water flow.

[0052] This application embodiment monitors the eye opening and closing degree and pupil response parameters of the subject in real time during eye rinsing, and dynamically determines the water flow parameters based on these two physiological feedback indicators. This allows the eyewash station to adaptively match individual differences among users in terms of contamination level, pain sensitivity, and stress response. Thus, while ensuring rinsing safety, it provides more intense or longer-lasting effective rinsing for users with heavier contamination or higher tolerance. Simultaneously, it automatically reduces water flow stimulation for users with lighter contamination or lower tolerance to avoid secondary injury. This improves the eye cleaning effect and rinsing comfort for different individuals, overcoming the problem of incomplete rinsing or over-stimulation for some users caused by a "one-size-fits-all" approach under fixed parameter modes. Therefore, it enhances the adaptability and rinsing efficiency of the eyewash station in complex emergency scenarios.

[0053] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S20 may include: Step S201: Obtain the current stage of the rinsing process and determine the preset reference water flow parameters corresponding to the stage, wherein the stage is one of the rapid rinsing stage, the gentle rinsing stage, and the soothing massage stage arranged in chronological order. Step S202: Using the preset reference water flow parameter as the upper limit, determine the water flow parameter based on the eye opening and closing degree and the pupil response parameter.

[0054] The current stage of the rinsing process refers to the rinsing rhythm state determined by the time interval within the preset total rinsing time, based on the current rinsing time. It characterizes the macroscopic progress of the rinsing process over time. The rapid rinsing stage refers to the time interval at the beginning of the rinsing process, where a high-flow rinsing mode is used to quickly dilute and flush away harmful substances in the initial stage of contact with the eyeball. The gentle rinsing stage refers to the time interval after the rapid rinsing stage, where a medium-flow rinsing mode is used to continue rinsing with a gentler water flow after the harmful substances have been initially diluted. The soothing massage stage refers to the time interval at the end of the rinsing process, where a low-flow pulse or intermittent water flow is used to simulate a gentle massage effect at the end of rinsing to relieve eye discomfort.

[0055] Preset reference flow parameters refer to a set of flow parameter values ​​that are pre-associated and bound to each stage, serving as the reference for flow control in that stage. These include reference flow rate and / or reference flow intensity, and are used to set an upper limit reference value for flow control in that stage. "Using the preset reference flow parameters as the upper limit" means that when actually determining the flow parameters, the final output flow rate and / or flow intensity will not exceed the value corresponding to the preset reference flow parameters. In other words, the preset reference flow parameters serve as the maximum value constraint for the actual control quantity.

[0056] The controller first obtains the duration of the current rinsing process and determines whether it is currently in the rapid rinsing stage, the gentle rinsing stage, or the soothing massage stage based on the duration. Then, based on the determined stage, it reads the preset reference water flow parameter corresponding to that stage from the preset stored data. This reference water flow parameter represents the maximum water flow value that can be used under ideal conditions (i.e., when the user's eyes are fully open and there is no pain stress). Finally, the controller uses this preset reference water flow parameter as an upper limit constraint and determines the actual output water flow parameter within the range not exceeding this upper limit based on the currently monitored eye opening and pupil response parameters. That is, when the eye condition is good, the output is close to the upper limit, and when the eye condition is poor (eyes closed or significant pain stress), the output is lower and further away from the upper limit.

[0057] In one feasible implementation, the controller starts timing when rinsing begins and determines the current stage based on the current rinsing time: when the rinsing time is between 0 and 5 seconds, it is determined to be a rapid rinsing stage, and the controller uses 90% of the rated flow rate as the preset reference water flow rate for this stage and 100% of the rated water flow intensity as the preset reference water flow intensity value for this stage, so as to quickly flush away harmful substances from the surface of the eyeball; when the rinsing time is between 5 and 20 seconds, it is determined to be a gentle rinsing stage, and the controller uses 60% of the rated flow rate as the preset reference water flow rate for this stage and 60% of the rated water flow intensity as the preset reference water flow intensity value for this stage, and dynamically adjusts the reference water flow rate and / or reference water flow intensity for this stage based on the real-time monitoring results of eye opening and closing; when the rinsing time is between 20 and 30 seconds, it is determined to be a soothing massage stage, and the controller controls the water flow to be output in a low-flow pulse or intermittent water flow mode, and the corresponding reference water flow intensity is reduced to 30% of the rated value. The time length and baseline flow / intensity ratio of each stage mentioned above are only examples. In actual applications, they can be adjusted according to the specific model of the eyewash station, water supply conditions, and usage scenarios.

[0058] In this embodiment, step S202 may include: Step A10: Based on the eye opening and closing degree, determine the water flow rate within the current control cycle; Step A20: Based on the pupil response parameters, determine the water flow intensity within the current control cycle; Step A30: The water flow rate and the water flow intensity are used as the water flow parameters.

[0059] The current control cycle refers to the time unit corresponding to the controller executing one complete "monitor-decision-execution" cycle. It is a preset fixed time length used to discretize the continuous eye irrigation process into multiple control intervals arranged sequentially in time. Water flow rate refers to the amount of water passing through the nozzle assembly outlet per unit time, used to control the amount of irrigation water. Water flow intensity refers to the impact force or velocity of the water flow, used to control the gentleness of the irrigation water flow. Water flow rate and water flow intensity together constitute the water flow parameters, corresponding to the "quantity" and "force" dimensions of the irrigation water flow, respectively.

[0060] After acquiring the eye opening and pupil response parameters for the current control cycle, the controller makes independent decisions based on these two monitored parameters: It determines the water flow rate for the control cycle based on the current value of the eye opening, setting a higher flow rate when the eye opening is large and a lower flow rate when the eye opening is small; it determines the water flow intensity for the control cycle based on the current value of the pupil response parameter, setting a lower flow intensity when the pupil response parameter indicates a high level of pain stress and a higher flow intensity when the stress level is low; then, it combines the determined water flow rate and flow intensity into the water flow parameters for the current control cycle, serving as a unified instruction for flushing execution within that control cycle.

[0061] In this embodiment, step A10 may include: Step A101: Determine the switching frequency of the eye opening and closing degree between open and closed eyes within a preset time period before the current moment; Step A102: When the switching frequency is greater than the preset frequency, the water flow rate in the current control cycle is determined according to the switching frequency, wherein the switching frequency is negatively correlated with the water flow rate; Step A103: When the switching frequency is less than or equal to the preset frequency, the water flow rate in the current control cycle is determined according to the eye opening and closing degree, wherein the eye opening and closing degree and the water flow rate are positively correlated.

[0062] The preset duration prior to the current moment refers to a time window formed by looking back a fixed period of time from the current moment. It is used to extract historical data on eye opening and closing within a recent period as an analysis sample for switching frequency statistics. Switching frequency refers to the ratio of the number of times the eye opening and closing alternates between open and closed states within the aforementioned preset duration time window to the preset duration. It is used to characterize the frequency of blinking or the instability of eyelid state.

[0063] The preset frequency refers to the pre-set switching frequency threshold, which is used to distinguish whether the user's eye condition changes fall within the normal physiological blinking range or the range of abnormally frequent stress-induced eye closure. When the switching frequency exceeds this threshold, it indicates that the user's eye condition changes too frequently and may be in a state of severe pain or extreme discomfort.

[0064] A negative correlation refers to the inverse relationship between switching frequency and water flow rate; that is, the higher the switching frequency, the lower the water flow rate, and vice versa. This is used to actively reduce the water flow rate when eye closure occurs frequently to avoid exacerbating discomfort. A positive correlation refers to the unidirectional relationship between eye opening and closing degree and water flow rate; that is, the greater the eye opening and closing degree (the more open the eyes), the greater the water flow rate, and the smaller the eye opening and closing degree (the more closed the eyes), the lower the water flow rate. This is used to adjust the water flow rate according to the actual degree of eye opening when the eye condition is stable.

[0065] The controller first acquires historical data on eye opening and closing within a preset time frame prior to the current moment. It then calculates the switching frequency by dividing the total number of times the eye opening and closing switch between open and closed within that time window by the preset time frame. Next, it determines whether this switching frequency is greater than the preset frequency. If the switching frequency is greater than the preset frequency, it indicates that the user is frequently blinking or closing their eyes, potentially indicating choking or pain stress. In this case, the controller determines the water flow rate within the current control cycle based on the switching frequency, with a higher switching frequency resulting in a lower water flow rate to reduce water stimulation. If the switching frequency is less than or equal to the preset frequency, it indicates that the user's eyelid state changes are within the normal range. In this case, the controller directly determines the water flow rate based on the current eye opening and closing; a higher eye opening (more open eyes) results in a higher water flow rate, and vice versa.

[0066] Thus, by introducing the frequency of eye opening and closing within a preset time as a criterion, this embodiment of the application can distinguish between normal physiological blinking and stress-induced frequent eye closing caused by pain or choking on water. It adopts two strategies for different situations: negative correlation adjustment of switching frequency and positive correlation adjustment of opening and closing degree. This avoids controlling the water flow in the conventional way when there is severe pain or extreme discomfort. In this way, the flow rate is actively reduced to relieve discomfort when the eye condition is unstable, and precise adjustment is maintained when the eye condition is stable, thereby improving the safety and comfort of water flow control.

[0067] In this embodiment, step A20 may include: Step A201: Determine the pain stress level of the subject being rinsed based on the pupillary response parameters; Step A202: Determine the water flow intensity within the current control cycle based on the pain stress level, wherein the pain stress level and the water flow intensity are negatively correlated.

[0068] Pain stress level is a quantitative indicator, determined based on pupillary response parameters, used to characterize the degree of physiological pain or discomfort experienced by the subject at a given moment due to water flow stimulation. It reflects the user's eye sensitivity and tolerance to the rinsing stimulus. A negative correlation refers to the inverse relationship between pain stress level and water flow intensity; that is, a higher pain stress level corresponds to a lower determined water flow intensity, and vice versa. This is used to automatically reduce the water flow impact to alleviate discomfort when the user exhibits strong pain stress, while maintaining sufficient rinsing effectiveness when the user has good tolerance.

[0069] After acquiring the pupil response parameters for the current control cycle, the controller compares these parameters with multiple preset stress level thresholds or calculates them using a preset mapping relationship, converting them into a level value that characterizes the current level of pain stress. Then, the controller determines the water flow intensity for the current control cycle based on this pain stress level, mapping according to the rule that the higher the pain stress level, the lower the water flow intensity. For example, when the user exhibits significant pupil constriction (indicating a high level of pain stress), the controller reduces the water flow intensity to reduce the water flow impact; when the user's pupil response is stable (indicating a low level of pain stress), the controller maintains or increases the water flow intensity to ensure the rinsing effect.

[0070] For example, such as Figure 3 The diagram shows the control process of the eyewash station. During the eyewash process, the eye opening and closing degree and pupil response parameters of the subject are monitored in real time. At the same time, the current stage of the rinsing process is obtained. The preset reference water flow parameters (including reference water flow rate and reference water flow intensity) corresponding to the current stage are used as the upper limit. Based on the currently monitored eye opening and closing degree and pupil response parameters, the water flow parameters are determined. The eyewash is performed on the subject according to the water flow parameters within the current control cycle.

[0071] Thus, this embodiment divides the rinsing process into multiple stages arranged in chronological order and sets corresponding preset reference water flow parameters for each stage. Simultaneously, it independently determines the water flow rate and water flow intensity based on eye opening and closing degree and pupil response parameters. The determination of the water flow rate comprehensively considers the frequency of eye opening and closing and the current opening degree, while the determination of the water flow intensity is based on the pain stress level represented by the pupil response parameters and is adjusted inversely. This achieves coordinated adaptive control of the rinsing water flow in both macroscopic time rhythm and microscopic real-time feedback dimensions. This ensures the targeted rinsing effect at each stage and proactively reduces water flow stimulation when the user experiences frequent eye closure or pain stress, thereby improving the safety, comfort, and effectiveness of the rinsing process.

[0072] In this embodiment, the eyewash station control method of this application further includes: Step B10: During the process of rinsing the eyes of the object being rinsed, a monitoring image of the object being rinsed is acquired.

[0073] Monitoring images refer to image data collected by visual sensors during the rinsing process that covers the user's body area to observe their overall posture and movement. Their field of view is larger than that of facial images used for eye monitoring, and includes at least the user's head, shoulders, and torso area, for subsequent posture recognition and motion trajectory analysis.

[0074] During the rinsing process, in addition to acquiring facial images with a narrower field of view for monitoring eye opening and pupil response parameters, the visual sensor also simultaneously acquires monitoring images of body areas including the user's head, shoulders, and torso with a wider field of view. The controller continuously acquires these monitoring images at a preset acquisition frequency and outputs them to subsequent posture recognition and motion trajectory analysis steps.

[0075] Step B20: Identify the posture and / or motion trajectory of the object being rinsed based on the monitoring image.

[0076] Posture refers to the shape and orientation of the body being washed in space. It is extracted from the monitoring image through human key point detection and is used to characterize whether the user is currently standing, sitting, or in a fallen state. Motion trajectory refers to the path formed by the change in position of the body or body part of the object being washed over time in the monitoring image sequence. It is extracted from the monitoring image sequence through inter-frame tracking and differential analysis and is used to characterize whether the user's motion characteristics meet preset abnormal conditions.

[0077] The controller inputs the acquired monitoring images into a pre-trained posture recognition model. This model performs key point detection and posture classification on the human body region in the image and outputs the user's current posture category (such as standing posture, sitting posture, or falling posture). At the same time, the controller performs position tracking and motion analysis on the human body region in multiple consecutive monitoring images, calculates the displacement, movement speed, and movement direction of the human body contour or human body key points in the image coordinate system, and forms motion trajectory features.

[0078] Step B30: When the posture is detected as a falling posture, the movement trajectory meets a preset static timeout condition, or the movement trajectory meets a preset violent struggle condition, a safety response operation is executed, wherein the safety response operation includes at least one of pausing flushing, reducing water flow intensity, and issuing an alarm signal.

[0079] A falling posture refers to an abnormal body position determined by posture recognition, indicating that the user's body has lost its normal upright position and is either lying down or about to fall. A stationary timeout condition is a preset condition that triggers an abnormal judgment when the user has not made any effective displacement or posture change within a preset time period; it is used to identify whether the user has lost the ability to move due to unconsciousness, fainting, or other reasons. A violent struggle condition is a preset condition that triggers an abnormal judgment when the user's movement amplitude and speed exceed a preset threshold; it is used to identify whether the user is making dangerous involuntary movements due to severe pain or panic. Safety response operations refer to protective actions automatically executed by the controller after recognizing the above abnormal postures or movement trajectories to ensure user safety; these include at least one of the following: pausing flushing to stop the water flow impact, reducing the water flow intensity to reduce the level of irritation, and issuing an alarm signal to notify on-site personnel to intervene.

[0080] After acquiring the results of posture recognition and motion trajectory analysis, the controller matches these results against preset abnormal conditions: determining whether the current posture is a fall posture, whether the motion trajectory meets the static timeout condition, and whether the motion trajectory meets the violent struggle condition. When any of the above conditions are met, the controller determines that the user is currently in a dangerous state and then selects at least one from the preset set of safety response operations to execute. For example, it can pause rinsing to completely eliminate the water flow impact, reduce the water flow intensity to reduce stimulation while maintaining rinsing, issue an audible and visual alarm signal to notify surrounding personnel to intervene, or combine the above actions. The safety response operations continue to be executed until on-site personnel manually reset or the controller detects that the user's state has returned to normal.

[0081] In one feasible embodiment, the eyewash station is equipped with a human-machine interface panel, which includes at least a digital display screen, multi-color LED status lights, and / or an audible and visual alarm. The digital display screen shows the current water pressure, eye opening and closing status, pupil response status, and the current operating mode of the system in real time. The multi-color LED status lights indicate different operating states of the system (e.g., standby, running, alarm). The audible and visual alarm is triggered by the controller when a system abnormality occurs (e.g., abnormal water pressure, equipment malfunction, abnormal user status, etc.), emitting an audible and visual warning signal.

[0082] The eyewash station is also equipped with a data interface for connecting to an IoT module to enable data communication between the eyewash station and external devices. Through this data interface and the IoT module, the controller can upload water pressure data, eye monitoring data, and device operating status data to a remote server or monitoring terminal for remote monitoring, data recording, and fault diagnosis by management personnel. At the same time, the data interface also supports receiving remote commands to enable predictive maintenance and remote system upgrades.

[0083] The eyewash station is also equipped with a voice interaction module, which includes at least a microphone and a speaker, used to collect the user's voice commands and provide voice feedback to the user, respectively. When the recognized voice command is from a preset command set, the controller executes the corresponding control operation; the preset command set includes at least one or more of the following: stop rinsing, continue rinsing, request help, and adjust water flow.

[0084] Thus, this embodiment of the application acquires monitoring images and identifies the user's posture and movement trajectory simultaneously during the rinsing process. It automatically executes safety response operations in three abnormal situations: falling posture, prolonged stillness, and violent struggle. By associating water flow control and alarm mechanisms with the user's real-time safety status, it effectively prevents the risk of choking and suffocation due to loss of consciousness during rinsing and the risk of secondary injury due to violent struggle, significantly improving the safety guarantee capability of the eyewash station in emergency scenarios.
