Description

Technical Field

[0001] The present invention belongs to the technical field of centralized control rooms, and in particular relates to a dynamic lighting method and system for a centralized control room that takes into account adaptation to the natural rhythm of the human body. Background Art

[0002] Due to the special nature of the work in the centralized control room, the main control room of the power plant must have someone on duty at night to monitor the panels. Long-term "working against the clock" will affect the physical and mental health of the staff on duty. For example, most accidents occur in the early morning when physiological activity is at its lowest. Since the human body's system responsible for controlling 24-hour rhythms is the suprachiasmatic nucleus of the hypothalamus located behind the eyes, the adverse effects of shift work can be mitigated through healthy lighting design. Healthy lighting takes into account the impact of light on the human body's biological rhythms and improves people's work efficiency by simulating the cyclical changes of natural light.

[0003] Current approaches to healthy lighting, such as those used in control rooms, automatically adjust illuminance and color temperature based on time to simulate natural light, such as sunrise and sunset. This helps improve staff mood and ensure work efficiency. However, while these lighting methods can automatically adjust illuminance and color temperature, they fail to consider the time periods of the control room's shift schedules, the actual work needs of staff in different areas of the control room, and the impact of outdoor lighting conditions on contrast and color temperature. As a result, the adjusted illuminance and color temperature do not provide a comfortable level of comfort for staff and do not meet the work lighting needs within the control room. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a dynamic lighting method and system for the control room that takes into account the adaptation to the natural rhythm of the human body. The present invention dynamically adjusts the illuminance and color temperature of the lighting equipment in the control room according to the time stage of the cycle time; and further adjusts the illuminance and color temperature in the human rhythm lighting layout area and the four-season rhythm lighting layout area according to the length of time the operator maintains the posture and the outdoor lighting conditions; takes into account the time cycle characteristics of the control room scheduling, as well as the actual work needs of the staff in different areas of the control room and the outdoor lighting conditions and other effects on the contrast and color temperature. The adjusted illuminance and color temperature are adapted to the environment of each area of the control room, thereby improving the lighting comfort and being able to better meet the needs of work lighting and the like.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, the present invention provides a method for dynamic lighting in a control room that takes into account the natural rhythm of the human body, comprising:

[0007] Obtain a cycle time for the control room work schedule and outdoor lighting parameters;

[0008] The cycle time is divided into four time stages according to the time variation patterns of sunrise, steady state after sunrise, sunlight intensity at noon, and the decline of sunlight intensity; and the control room is divided into human rhythm lighting layout area and four seasons rhythm lighting layout area;

[0009] According to the time stage of the cycle time, the illumination and color temperature of the lighting equipment in the control room are dynamically adjusted; and according to the length of time the operator maintains the posture and the outdoor lighting parameters, the illumination and color temperature in the human rhythm lighting layout area and the four-season rhythm lighting layout area are further adjusted respectively; among them, the illumination and color temperature in the time stage corresponding to the sunrise are lower than the illumination and color temperature in the time stage corresponding to the sunlight intensity; the illumination and color temperature in the time stage corresponding to the sunlight intensity are lower than the illumination and color temperature in the time stage corresponding to the stable state after the sunrise; the illumination and color temperature in the time stage corresponding to the stable state after the sunrise are lower than the illumination and color temperature in the time stage corresponding to the sunlight illumination at noon.

[0010] Furthermore, the illuminance and color temperature in the time period corresponding to the sunrise are 400lx and 3600k respectively; the illuminance and color temperature in the time period corresponding to the stable state after the sunrise are 600lx and 4800k respectively; the illuminance and color temperature in the time period corresponding to the noon sunlight illuminance are 650lx and 5300k respectively; and the illuminance and color temperature in the time period corresponding to the sunlight intensity are 450lx and 4000k respectively.

[0011] Furthermore, the control room is divided into human rhythm lighting layout area, four-season rhythm lighting layout area and visiting activity lighting layout area; in the human rhythm lighting layout area, when the operator maintains a posture for more than the preset time, the local lighting above the operator will be compensated by the stepless dimming method of slowly lowering the color temperature value and increasing the illuminance value based on the current rhythm lighting parameters.

[0012] Furthermore, as the posture holding time increases, the color temperature value is reduced and the illuminance value is increased, until the color temperature value is reduced to the minimum value of the preset range and the illuminance value is increased to the maximum value.

[0013] Furthermore, in the seasonal lighting layout area, adjust the seasonal lighting parameters in the non-operation station operation area: current illuminance = 300 + outdoor illuminance value / 100*2, current color temperature = outdoor color temperature*0.9.

[0014] Furthermore, the human body rhythm lighting layout area covers the operation area of the operation station, the four seasons rhythm lighting layout area covers the activity area around the operation station, and the visiting activity lighting layout area is set in the rear area of the overall space of the control room.

[0015] In a second aspect, the present invention further provides a dynamic lighting system for a control room that takes into account the natural rhythm of the human body, including:

[0016] The data acquisition module is configured to obtain a cycle time of the work schedule in the control room and outdoor lighting parameters;

[0017] The cycle time segmentation module is configured to divide the cycle time into four time stages according to the time variation patterns of sunrise, steady state after sunrise, noontime sunlight illumination, and decline of sunlight intensity; and to divide the control room into human rhythm lighting layout areas and four seasons rhythm lighting layout areas;

[0018] The lighting control module is configured to: dynamically adjust the illuminance and color temperature of the lighting equipment in the control room according to the time stage of the cycle time; and further adjust the illuminance and color temperature in the human rhythm lighting layout area and the four-season rhythm lighting layout area according to the length of time the operator maintains the posture and the outdoor lighting parameters; among which, the illuminance and color temperature in the time stage corresponding to the sunrise are lower than the illuminance and color temperature in the time stage corresponding to the sunlight intensity; the illuminance and color temperature in the time stage corresponding to the sunlight intensity are lower than the illuminance and color temperature in the time stage corresponding to the stable state after the sunrise; the illuminance and color temperature in the time stage corresponding to the stable state after the sunrise are lower than the illuminance and color temperature in the time stage corresponding to the sunlight illumination at noon.

[0019] In a third aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the dynamic lighting method for a control room that takes into account adaptation to the natural rhythm of the human body as described in the first aspect.

[0020] In a fourth aspect, the present invention also provides an electronic device comprising a memory, a processor, and a computer program stored in the memory and capable of running on the processor. When the processor executes the program, the steps of the dynamic lighting method for the control room that takes into account adaptation to the natural rhythm of the human body as described in the first aspect are implemented.

[0021] In a fifth aspect, the present invention further provides a computer program product, which includes a computer program. When the computer program is executed by a processor, it implements the steps of the dynamic lighting method for the control room that takes into account adaptation to the natural rhythm of the human body as described in the first aspect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the cycle time is divided into four time stages according to the time variation law of the sunrise, the stable state after the sunrise, the sunlight illumination at noon and the decline of the sunlight intensity; and the human body rhythm lighting layout area and the four-season rhythm lighting layout area are divided in the control room; then, the illumination and color temperature of the lighting equipment in the control room are dynamically adjusted according to the time stage of the cycle time; and the illumination and color temperature in the human body rhythm lighting layout area and the four-season rhythm lighting layout area are further adjusted according to the length of time the operator maintains the posture and the outdoor lighting conditions; taking into account the time cycle characteristics of the control room scheduling, as well as the actual work needs of the staff in different areas of the control room and the outdoor lighting conditions and other effects on contrast and color temperature, the adjusted illumination and color temperature are adapted to the environment of each area of the control room, thereby improving the lighting comfort and being able to better meet the needs of work lighting, etc.

[0024] 2. In the present invention, in the human body rhythm lighting arrangement area, when an operator maintains a posture for longer than a preset time, the local lighting above the operator is compensated by a stepless dimming method that slowly reduces the color temperature and increases the illuminance based on the current rhythm lighting parameters. As the posture is maintained for longer, the color temperature is reduced and the illuminance is increased, until the color temperature is reduced to the minimum value and the illuminance is increased to the maximum value within the preset range. In addition, in the four-season lighting arrangement area, the four-season lighting parameters in the non-operating station work area are adjusted according to the outdoor lighting conditions. Through dynamic adjustment, the connection between the lighting parameters and the personnel and the environment is further increased, thereby further alleviating problems such as work fatigue of the personnel.

[0025] 3. The present invention improves on traditional directional zoned lighting to achieve intelligent dynamic lighting that reflects the natural cycle characteristics of the human body, and tailors lighting solutions for operators in each duty cycle period.

[0026] 4. Based on the changing weather characteristics of the four seasons, the present invention sets up a four-season rhythm lighting arrangement in the non-operation station operation area, connecting the indoor and outdoor space environment feelings in the form of lighting, which is beneficial to the physical and mental health of indoor duty personnel and improves the lighting comfort for the staff in the control room.

[0027] 5. This invention is based on mature LED and sensor technologies and can be easily integrated into existing control rooms, reducing the probability of errors in production tasks and greatly improving work efficiency. It breaks through the design thinking of conventional control room lighting and sets three major lighting areas based on the special environmental space and duty time mechanism. The light intensity and color temperature are optimized accordingly to improve the work comfort of control room operators, relieve fatigue, and enhance concentration.

[0028] 6. The present invention realizes fully automated intelligent control work, provides an effective method for human body rhythm, resets the human body clock according to the changes in human biological rhythm, resists the influence of nature's "time divider", and finds a work rhythm that suits the human body's 24-hour natural cycle. Excellent lighting that is consistent with the employees' work cycle rhythm not only has a huge impact on work behavior, but also improves work efficiency and reduces the chance of production accidents.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0040] Example 1:

[0041] Humans are highly sensitive to light, and the so-called "biological clock" or "circadian rhythm" exists in every cell and organ of the human body. It resides in the suprachiasmatic nucleus (SCN), located in the anterior hypothalamus, above the optic chiasm. Based on the amount of light it receives, it regulates the body's natural 24-hour cycle. It controls when to sleep and when to be active. For example, light exposure 1.5 to 2 hours before waking up in the morning determines the body's wakefulness time and body temperature. This brain region is also responsible for regulating body temperature, alertness, and the normal secretion and function of hormones from day to night. Furthermore, the body's learning and memory abilities, mood, and work efficiency are significantly influenced by the circadian rhythm. Currently, lighting systems designed for control room installations only meet a single standard of illuminance of 300 to 500 lux, a uniformity of no less than 0.7, and no glare, with a glare limit of Level I. However, this single lighting environment cannot compensate for the adverse effects of the human body's natural cycle.

[0042] As the "brain" and "nerve center" of power generation at power plants, the centralized control room is not only responsible for monitoring, managing, and coordinating power generation operations, but also plays a vital role in emergency response and information sharing during emergencies. Due to the specialized nature of centralized control room work, personnel must monitor and monitor the panels in the power plant's main control room at night. This long-term "working against the clock" can negatively impact the operator's physical and mental health. Most accidents occur in the early morning, when physiological activity is at its lowest in the body's natural 24-hour cycle. Because the body's system responsible for controlling 24-hour rhythms is located in the suprachiasmatic nucleus of the hypothalamus, behind the eyes, lighting design can mitigate the adverse effects of shift work.

[0043] Based on this, this embodiment provides a dynamic control room lighting method that adapts to the human body's natural rhythms. This method creates a flexible lighting space, enhances comfort, and complements human rhythms, thereby helping employees better concentrate and making their work easier. Dynamic lighting can be adjusted according to employees' shift times and their own biorhythms. By controlling the lighting, an environment based on the employees' natural 24-hour cycles is created. Furthermore, excellent lighting that aligns with the rhythm of employees' work cycles not only significantly impacts work behavior, but also improves work efficiency and reduces the likelihood of production accidents.

[0044] Optionally, in this embodiment, the hardware parts that may be used include a control module (duty time preset device, work cycle time control device), a sensor module (human body data acquisition device, infrared thermal sensing device), an intelligent light source module (color temperature, integrated RGB), etc.; the software part may include a dynamic lighting algorithm (based on the conclusions calculated based on human body rhythms, adjusting lighting parameters according to different time periods and different behavior patterns), a user interaction interface, etc., which work together to coordinate.

[0045] In this embodiment, a cycle time for the work schedule is first determined; then, the cycle time is divided into four time stages according to the time variation patterns of sunrise, stable state after sunrise, noon sunlight illumination, and decline in sunlight intensity; finally, the illumination and color temperature of the lighting equipment in the control room are dynamically adjusted according to the time stage of the cycle time; wherein, the illumination and color temperature in the time stage corresponding to sunrise are lower than the illumination and color temperature in the time stage corresponding to sunlight intensity; the illumination and color temperature in the time stage corresponding to sunlight intensity are lower than the illumination and color temperature in the time stage corresponding to the stable state after sunrise; and the illumination and color temperature in the time stage corresponding to the stable state after sunrise are lower than the illumination and color temperature in the time stage corresponding to sunlight illumination at noon. Optionally, the work mode can be preset according to the duty characteristics of the control room requiring 24-hour three-shift operation. The three-shift work mechanism is divided into three shift cycles according to 24 hours. Each cycle is divided into four time periods: A, B, C and D (A period is 8:00-10:00, B period is 10:00-12:00, C period is 12:00-14:00, and D period is 14:00-16:00). Different lighting parameters are set for each time period to compensate for the physiological rhythm characteristics of the operators at that time, so as to solve the adverse effects of individual differences in different time periods on work status and human health, and at the same time improve working conditions to a certain extent.

[0046] According to the work duty cycle and the changes in human biological rhythm, the lighting compensation method is used to simulate the time changes of morning, noon and evening in a day to adapt to the operator's human rhythm.

[0047] Each duty cycle is divided into two-hour segments, and the infinitely changing lighting is set to 4 modes:

[0048] Period A (8:00-10:00) is "wake-up mode": soft lighting simulates the morning sunrise, injecting vigor and vitality into the control room. At this time, blood pressure and heart rate increase, and body temperature also rises.

[0049] Time period B (10:00-12:00) is the "vitality mode": the light is bright and even, simulating the stable state after the sun rises. At this time, the human body is full of energy and vitality, which is the most suitable time for work.

[0050] Period C (12:00-14:00) is "focus mode": illuminance gradually decreases while color temperature stabilizes. This simulates the intensity of midday sunlight. Since the human body needs rest and is prone to fatigue at this time, the color temperature is temporarily lowered to adapt to the body's rhythmic mechanism, helping on-duty personnel quickly adjust their physical state and enter a focused work mode.

[0051] Period D (2:00 PM - 4:00 PM) is "Relax Mode": During this time, the simulated sunlight intensity begins to decrease. Human body temperature rises, and work capacity and efficiency reach their peaks, nearing the end of the shift cycle. By gradually adjusting the color temperature and reducing the brightness, a transition to the warmer Relax Mode can be achieved.

[0052] Periods A, B, C, and D can be defined as the first, second, third, and fourth time periods, respectively. The first time period can be understood as the first time period within the entire cycle from start to finish in different shift phases; the fourth time period can be understood as the last time period within the entire cycle from start to finish in different shift phases.

[0053] In this embodiment, Figure 1 and Figure 2 As shown, the control room is divided into three areas: human rhythm lighting, seasonal lighting, and visitor activity lighting. In the human rhythm lighting area, if an operator maintains a posture for longer than a preset duration, the local lighting above the operator is compensated by a stepless dimming method based on the current rhythm lighting parameters, slowly decreasing the color temperature and increasing the illuminance. As the posture is held for longer, the color temperature decreases and the illuminance increases, until the color temperature reaches the minimum and illuminance reaches the maximum within the preset range. In the seasonal lighting area, seasonal lighting parameters are adjusted for non-operating station work areas: current illuminance = 300 + outdoor illuminance value / 100 * 2, and current color temperature = outdoor color temperature * 0.9. It is understood that the outdoor lighting parameters, such as illuminance and color temperature, can be understood as the lighting parameters of the control room's outdoor lighting, moonlight (at night), sunlight (during the day), or other light sources.

[0054] Optionally, in the human rhythm lighting arrangement area: the human body data collection device is combined with relevant working postures to determine the activity type of personnel in the control room and dynamically adjust the lighting parameters; when the infrared thermal sensing device determines that the operator maintains a posture for a long time, the local lighting above the operator is based on the current rhythm lighting parameters and uses an infinitely variable light method to slowly reduce the color temperature value (current color temperature * 0.8) and increase the illuminance value (current illuminance * 1.5) to perform lighting compensation, which has the effect of relieving fatigue. In the four-season lighting arrangement area: the outdoor ambient light feedback device is used to adjust the four-season lighting parameters in the non-operating station operation area. Its dynamic lighting algorithm is: current illuminance = 300 + outdoor illuminance value / 100 * 2, current color temperature = outdoor color temperature * 0.9. In the visiting activity lighting arrangement area: the infrared thermal sensing device is used to determine whether there is a visiting activity in the current period, and the lighting parameters of the rear area of the overall space of the control room are adjusted.

[0055] The human body rhythm lighting layout area covers the operation area of the operation station, the four seasons rhythm lighting layout area covers the activity area around the operation station, and the visiting activity lighting layout area is set in the rear area of the overall space of the control room.

[0056] In this embodiment, the human body data collection device makes judgments based on the following sample table, using a stepless dimming method to provide lighting compensation, dynamic prompts, and fatigue relief. Activity types and related postures are shown in Table 1.

[0057] Table 1 Activity types and related postures

[0058] Activity Type Typical working posture Sitting posture Duration Monitor instruments on the console Sitting, standing Lean back and relax Long (main posture) Monitor vertical screen and simulation screen Sitting, standing Lean back and relax Long (main posture) Manipulate the controller on the console Sitting, standing Upright, forward-leaning Irregular - short term Operate the vertical on-screen controller stand -- Short-term Logging data to the console sit Lean forward Occasional, short-term Use a writing tablet to record data on the vertical screen stand Handle operation ticket Sitting, standing Upright, forward-leaning Irregular-Irregular Adjustment and control instruments Sitting, standing Lean forward Occasional, short-term repair Standing, kneeling, squatting, bending over Irregular

[0059] For the activity type corresponding to a long time, the following steps are executed: lower the color temperature value (current color temperature * 0.8) and increase the illuminance value (current illuminance * 1.5); as the posture time increases, the color temperature value is lowered (current color temperature * 0.8) and the illuminance value is increased (current illuminance * 1.5) until it reaches the minimum color temperature value and the maximum illuminance value in the preset range.

[0060] like Figure 2 As shown, the structure of the control room has certain particularities compared to other office spaces. In the control center, there are at least fixed sitting workstations. In this embodiment, the space where the dynamic lighting part is applied mainly includes one or more visual display terminals (VDTs), communication tools, and workstation spaces including space for managing and placing documents. The layout of the control center's operating area is usually set as shown in the figure below (two rows facing the large screen: one row for operators on duty in the front and one row for supervisors' desks in the back). In addition to this operating area, the surrounding space may be set up with a rest and activity area, which is dynamically adjusted according to the real-time characteristics of the natural weather in the four seasons. Therefore, the coverage area of the human body rhythm lighting compensation part is the operating area of the operating station, the coverage area of the four-season rhythm lighting layout area is the activity area around the operating station, and the visiting activity lighting layout area is mainly set in the rear area of the overall space of the control room.

[0061] Example 2:

[0062] This embodiment provides a dynamic lighting method for a centralized control room that takes into account the natural rhythm of the human body, which supplements and further illustrates the embodiment.

[0063] First, the face recognition system at the entrance of the control room is used to determine whether the person entering is a person on duty; when it is determined that the person in the current control room is an on-duty operator, the rhythmic cycle lighting parameters that conform to the period of the current duty cycle are output according to the preset data of the duty time; further confirm whether the current time is the initial period of the group of duty cycles. If it is confirmed that the person entering is during period A of the duty cycle, it will automatically adjust to the initial settings of the control mode and output the lighting parameters; if the current time of face recognition is not the initial period of the duty cycle, the lighting parameters will not be changed and the current mode will be maintained.

[0064] If the facial recognition system at the entrance of the control room determines that the person entering is not a staff member on duty, it will further confirm whether the current behavior is consistent with the visit behavior of an outsider based on the analysis of the number of people collected by the sensor. If the visit activity is confirmed within the time period, the lighting mode will be automatically adjusted to the display mode and the lighting parameters will be output; if the sensor analysis shows that the person entering does not meet the visit behavior of an outsider, the lighting parameters under the default mode will be output.

[0065] Control mode: Based on the work duty cycle and the changes in human biological rhythm, the lighting compensation method is used to simulate the changes in the morning, noon and evening time of the day to adapt to the operator's human rhythm.

[0066] During the first time period (A period, 8:00-10:00): illuminance = 400lx, color temperature = 3600k; during the second time period (B period, 10:00-12:00): illuminance = 600lx, color temperature = 4800k; during the third time period (C period, 12:00-14:00): illuminance = 650lx, color temperature = 5300k; during the fourth time period (D period, 14:00-16:00): illuminance = 450lx, color temperature = 4000k.

[0067] Default mode: Illuminance = 300 lx, Color temperature = 5000 k. Display mode: Illuminance = 450 lx, Color temperature = 4800 k. Intelligent control: Combines facial recognition and image acquisition.

[0074] The lighting control module is configured to: dynamically adjust the illuminance and color temperature of the lighting equipment in the control room according to the time stage of the cycle time; and further adjust the illuminance and color temperature in the human rhythm lighting layout area and the four-season rhythm lighting layout area according to the length of time the operator maintains the posture and the outdoor lighting parameters; among which, the illuminance and color temperature in the time stage corresponding to the sunrise are lower than the illuminance and color temperature in the time stage corresponding to the sunlight intensity; the illuminance and color temperature in the time stage corresponding to the sunlight intensity are lower than the illuminance and color temperature in the time stage corresponding to the stable state after the sunrise; the illuminance and color temperature in the time stage corresponding to the stable state after the sunrise are lower than the illuminance and color temperature in the time stage corresponding to the sunlight illumination at noon.
