Example 1
As shown in fig. 1, the embodiment provides a smelting factory intelligent lighting control method based on production process requirements, which mainly comprises the following steps:
s1: obtaining production scene information of each process section on a production line of a smelting factory, wherein the production scene information comprises the requirement of a production process on illumination;
since the production process of the smelting industry generally comprises a plurality of process sections from raw materials to metallurgical finished products, a plurality of process sections are arranged in an on-line installation and generation mode of the smelting factory, and the process sections are arranged in a production workshop according to the sequence of the smelting and generation process. For example, a smelting plant generally comprises a coking process section, a sintering process section, a steelmaking process section, a continuous casting process section, an oxygen production process section and a steel rolling process section which are arranged in sequence.
Because different generating processes have different requirements on the illumination effect, the step obtains the requirements on the illumination effect required by each process.
S2: determining the brightness of the corresponding light source and the illumination set color temperature of each process section according to the production scene information of each process section;
the requirements of the respective process as described above for the lighting effect comprise at least the desired color temperature of the illumination of the respective process segment, i.e. the aforementioned illumination setting color temperature. The illumination setting color temperature may be set in advance empirically. For example, in a low color temperature environment of 5500K to 6500K, the human eyes are not easy to fatigue and have high comfort, and the human eyes have high identification degree in a high color temperature environment of 7500K to 9500K, but the eyes are easy to fatigue when watching for a long time. The equipment of the coking process and the sintering process is huge and mostly an automatic process, less personnel are needed, and the common illumination is basically adopted without considering the intelligent illumination requirement. The steelmaking process section and the casting process section are completed in a large workshop environment, and a skilled engineer is required to monitor the production engineering to ensure the product quality, so that the color temperature of the process sections is often set higher.
S3: acquiring the corresponding relation between each illumination light source and each process section;
a number of illumination sources are provided in the production plant, which are distributed in different locations in the production plant. Each process section has a corresponding illumination source for providing illumination thereto. The light source that provides illumination for a certain process segment is herein referred to as the illumination light source corresponding to that process segment.
S4: and controlling the light source brightness and the color temperature of each illumination light source when providing illumination according to the illumination set color temperature corresponding to each process section and the corresponding relation between each illumination light source and each process section.
The step controls the illumination light sources for providing illumination for each process section, so that the illumination light sources can illuminate for the corresponding process sections according to the set color temperature, and the color temperature of the illumination light sources can automatically adapt to the production requirements of the process sections.
In order to more accurately control the color temperature of each process section, the embodiment can also detect the environmental color temperature of each process section in real time. In this regard, as shown in fig. 2, the intelligent lighting control method for a smelting factory based on production process requirements of the present embodiment further includes the following steps:
s5: acquiring actual environment color temperatures of all process sections acquired by an environment sensor;
In this embodiment, environmental sensors capable of detecting environmental color temperatures may be provided at corresponding positions of each process segment in advance, and environmental color temperatures of each process segment are acquired by using these sensors in this step. In particular, a plurality of environment sensors can be allocated to each process section.
S6: comparing the actual ambient color temperature of each process section with the corresponding illumination setting color temperature to obtain a comparison result;
the present step compares the actual color temperature detected by the environmental sensor with the illumination setting color temperature, and as a result of the comparison, there are 3 cases where the actual color temperature is lower than the illumination setting color temperature, the actual color temperature is higher than the illumination setting color temperature, and the actual color temperature is equal to the illumination setting color temperature.
S7: and maintaining or adjusting the color temperature of each illumination light source according to the comparison result.
If the actual color temperature is lower than the illumination setting color temperature, the current color temperature of the illumination light source is regulated up, if the actual color temperature is higher than the illumination setting color temperature, the current color temperature of the illumination light source is regulated down, and if the actual color temperature is equal to the illumination setting color temperature, the current color temperature is kept unchanged.
In addition to the above-mentioned method for automatically adjusting the color temperature of the illumination source, the present embodiment also provides a method for enabling production management personnel to manually adjust the color temperature of the illumination source according to actual needs. In this regard, as shown in fig. 3, the intelligent lighting control method for a smelting plant based on the production process requirements in this embodiment further includes the following steps:
S8: acquiring and displaying the illumination setting color temperature and the actual environment color temperature corresponding to each process section on a display device;
in order to facilitate the field manager to grasp the actual color temperature and the illumination setting color temperature of the environment in which each process section is located, this step may be displayed on the display device. The display device includes, but is not limited to, a computer display screen, a touch display screen, and a display screen of a mobile terminal. In the specific display, different process sections can be displayed in different areas, and then the illumination set color temperature and the actual environment color temperature of each process section are displayed at the positions corresponding to the process sections.
S9: acquiring a manual color temperature adjusting instruction;
the user may input a manual adjustment instruction of the color temperature to the control system via the input device, which instruction may be a target adjustment value of the color temperature of the illumination, for example to adjust the color temperature of some illumination sources to 6000K. It may also be a target adjustment of the color temperature of the illumination, for example by reducing the color temperature of some illumination sources by 100k.
S10: and adjusting the color temperature of each illumination light source according to the illumination light source adjusting instruction.
As an alternative but advantageous embodiment, as shown in fig. 4, S2 is described in this example: determining the brightness of the light source and the set color temperature of the illumination corresponding to each process segment according to the production scene information of each process segment further comprises the following steps:
S21: determining the basic color temperature corresponding to each process section according to the production scene information of each process section;
for example, if the requirement of the coking process section for the color temperature of the illumination source is 6000k, the base color temperature corresponding to the coking process section is set to 6000k. For example, if the color temperature requirement of the lighting color light source in the sintering process section is 7000K, the basic color temperature corresponding to the sintering process section will be 7000K.
S22: acquiring adjacent relations among all process sections on a production line;
wherein the adjacent relationship between the individual process segments refers to the preceding process segment and/or the following process segment of each process segment. Wherein the adjacent relation between the process sections of smelting production is shown in figure 5.
S23: and determining intermediate transition color temperatures in gradient distribution between each adjacent process section on the basis of the basic color temperatures corresponding to each process section according to the adjacent relation between each process section.
Although the basic color temperature is the color temperature most suitable for the production scene of each process section, the basic color temperature between two adjacent process sections may be different, if the illumination color temperature corresponding to each process section directly adopts the basic color temperature, the environment color temperature at the junction of the two process sections is suddenly changed, and thus discomfort is caused to field personnel. As shown in fig. 6, fig. 6 shows the situation that the color temperature between two adjacent process segments is in gradient transition, and the higher the gray scale in fig. 6 is, the higher the color temperature is.
In this regard, the color temperature between two process segments is set on the basis of the basic color temperature between two adjacent process segments, so that the color temperature between the two process segments is gradually transited in a gradient increasing or gradient decreasing manner. For example, the coking process section has a basic color temperature of 6000K and the sintering process section has a basic color temperature of 7000K. The color temperature value of the intermediate transition color temperature between the coking process section and the sintering process section is gradually increased from the coking process section towards the sintering process section until the basic color temperature of the sintering process section is reached. By adopting the method, the color temperature between two adjacent process sections can be gradually transited, and the discomfort of field personnel caused by sudden change of the environmental color temperature is avoided.
S24: determining the illumination brightness requirements corresponding to each process section according to the production scene information of each process section;
the illumination brightness required by different process segments is often different, and the illumination brightness meeting the requirements of each process segment is obtained in this step.
S25: acquiring the natural brightness of each process section;
the brightness value of the natural light irradiated to each process section can be detected by a brightness sensor in the implementation.
S26: and determining the brightness of the light source corresponding to each process section according to the natural brightness and the illumination brightness requirement of each process section.
If the brightness of the natural light is enough, the brightness of the light source does not need to be increased, and if the brightness of the natural light is smaller than the illumination brightness requirement, the brightness of the light source can be increased, so that the total brightness of the natural light and the illumination light source meets the illumination brightness requirement.
In this embodiment, the production line at least includes a coking process section, a sintering process section, a steelmaking process section, a continuous casting process section, an oxygen production process section, and a steel rolling process section.
As shown in fig. 5, at S21: according to the production scene information of each process section, determining that the basic color temperature of the coking process section is 6000K, the basic color temperature of the sintering process section is 7000K, the basic color temperature of the steelmaking process section is 9000K, the basic color temperature of the continuous casting process section is 6000K, the basic color temperature of the oxygen production process section is 6000K, and the basic color temperature of the steel rolling process section is 7500K in the basic color temperatures of the process sections.
In this embodiment, the color temperature control of the illumination environment of each process segment is set according to the process characteristics. For example, the refining temperature of the steelmaking process is high, about 1500-2500 ℃, the water temperature of continuous casting and casting steel is up to 1500 ℃, the steel rolling process temperature is about 1000 ℃, and the rest working sections are mostly in a conventional room temperature environment.
As an alternative but advantageous embodiment, in this example, said S23: the step of determining the gradient distributed intermediate transition color temperature between each adjacent process segment based on the corresponding basic color temperature of each process segment according to the adjacent relation between each process segment further comprises the following steps:
s231: acquiring a preset color temperature difference threshold value;
the difference in color temperature is felt by the field staff as they travel from the area illuminated by one illumination source to the area illuminated by the other illumination source. If the color temperature difference is large, the field staff is influenced, so that the field staff cannot work normally. The color temperature difference threshold in the step is a color temperature difference threshold which does not affect the working personnel and can not work normally, and the threshold can be set through experiments or experience.
S232: acquiring the difference value between the number of illumination light sources between two adjacent process sections and the corresponding basic color temperature;
for example, the basic color temperatures between two adjacent process segments are Tq and Th, respectively, and the difference between the basic color temperatures corresponding to the two adjacent process segments is Tq-Th. The illumination source between two adjacent process segments refers to a light source for illuminating an area between two adjacent process segments, to which an on-site worker will pass when traveling from one process segment to the other process segment.
S233: calculating the number of required illumination light sources according to the difference value between the basic color temperatures and a preset color temperature difference threshold value;
the number of illumination sources required refers to the minimum number of illumination sources used in the case of satisfying the color temperature difference threshold requirement. Let the difference between the basic color temperatures be Tq-Th, the color temperature difference threshold Y, the number of required illumination sources n= |tq-th|/Y.
S234: judging whether the number of the required illumination light sources is larger than the number of the illumination light sources between two adjacent process sections;
s235: if yes, taking all illumination light sources between two adjacent process sections as target illumination light sources;
if the number of the required illumination sources is larger than the number of the illumination sources actually provided between the two adjacent process sections, the fact that the illumination sources actually provided between the two adjacent process sections cannot completely meet the requirement of a chromatic aberration threshold value is indicated, and all the illumination sources between the two adjacent process sections are fully utilized, so that the influence of chromatic aberration between the two adjacent illumination sources on staff is reduced.
S236: if not, selecting the same number of illumination sources as the required illumination sources from the illumination sources between two adjacent process sections as target illumination sources.
If the number of illumination sources required is smaller than the number of illumination sources actually present between two adjacent process segments, it is shown that the number of illumination sources actually present between two adjacent process segments may be satisfactory. At this time, a part of illumination light sources can be selected from the light sources between two adjacent process sections for generating the illumination effect of the color temperature gradient, and the number of the illumination light sources actually used for illumination is the same as the number of the required illumination light sources, so that the requirement of a color difference threshold can be met, the number of the illumination light sources can be reduced, and the energy is saved.
Since the requirement of the color difference threshold cannot be completely met even if all the illumination sources between two adjacent process segments are used when the number of illumination sources required is greater than the number of illumination sources actually present between the two adjacent process segments, this is an alternative but advantageous embodiment, in S235: if so, taking all illumination light sources between two adjacent process sections as target illumination light sources, and then further comprising the following steps:
s237: acquiring a person reference travelling speed and calculating the color temperature adaptation Time between each adjacent target light source, setting the absolute value of the color temperature difference between the two adjacent target light sources as delta T, and then obtaining the color temperature adaptation Time Time=k×delta T α ×e (β×ΔT) Wherein k, α and β are parameters;
when a worker enters a range irradiated by one target light source into a range irradiated by the other target light source, a certain adaptation time is needed to adapt to the color temperature difference between the two target light sources, and the time needed by the worker to adapt to the color temperature difference between the two target light sources is calculated by using the model. The parameters k, α and β in the foregoing model can be determined experimentally.
S238: determining a reference travel distance of the person in the irradiation range of each target light source according to the reference travel speed of the person and the color temperature adaptation time between each adjacent target light source;
wherein the personnel reference speed is the speed of the personnel walking on the production site, and the speed can be set empirically. Let the person reference travel speed be V, the reference travel distance s=v×time.
S239: and determining a travel path of a person from the current target light source irradiation area to the next adjacent target light source irradiation area according to each target light source irradiation range and the corresponding reference travel distance, and enabling the difference value between the distance of the travel path and the reference travel distance to be positioned in a section (0, a), wherein a is a positive number.
The value of a can be set empirically, and a certain redundancy is generally ensured, but in order to save time, the value of a can also be set to a smaller positive number. The difference between the distance of the travelling path and the reference travelling distance is within the interval (0, a), so that the travelling time of a person towards the area irradiated by the next target illumination light source according to the planned travelling path is longer than the adaptation time of human eyes to the color temperature difference, and the color temperature difference before adaptation can be achieved before the person reaches the next color temperature position.
In order to meet the requirement of the travelling distance, the travelling path can be planned to be in a folded line shape or an S shape, the distance between adjacent folding lines can be set according to the length of the travelling path, and in general, the longer the travelling path is, the shorter the distance between the adjacent folding lines is, and conversely, the longer the distance between the folding lines is.
In order to solve the problem of insufficient number of illumination light sources, as an alternative but advantageous implementation manner, the illumination light sources are strip-shaped, the illumination light sources between each two adjacent process sections are arranged in a fan shape, and after the illumination light sources are arranged in a fan shape, the illumination ranges of the illumination light sources also form a fan-shaped area because the illumination ranges of the strip-shaped illumination light sources are generally rectangular.
The S23: the step of determining the gradient distributed intermediate transition color temperature between each adjacent process segment based on the corresponding basic color temperature of each process segment according to the adjacent relation between each process segment further comprises the following steps:
S231B: acquiring the number of illumination sources between adjacent process sections;
S232B: obtaining a difference value between the basic color temperatures corresponding to the two adjacent process sections;
S233B: determining the color temperature difference between each adjacent illumination light source in two adjacent process sections according to the difference value between the basic color temperatures and the number of the illumination light sources between the adjacent process sections;
and if the number of the illumination light sources is n and the difference value between the basic color temperatures corresponding to the two adjacent process sections is Tq-Th, the color temperature difference between each adjacent illumination light source in the two adjacent process sections is (Tq-Th)/n.
S234B: determining the color temperature of each illumination light source in two adjacent process sections according to the basic color temperature corresponding to the two adjacent process sections and the color temperature difference between each adjacent illumination light source;
for two adjacent illumination sources, the color temperature of the latter illumination source is equal to the sum of the color temperature of the former illumination source and the color temperature difference between the adjacent illumination sources, e.g. the color temperature of the former illumination source is Tk and the color temperature of the latter illumination source is T (k-1), then there is T (k-1) =tk+ (Tq-Th)/n.
S235B: calculating color temperature adaptation Time according to the current color temperatures of two adjacent illumination light sources, and setting the color temperature difference distribution of two adjacent target light sources as Tf and Ta, wherein DeltaT= |Tf-Ta|, then the color temperature adaptation Time Time=k multiplied by DeltaT α ×e (β×ΔT) Wherein k, α and β are parameters;
S236B: acquiring an included angle of two adjacent illumination light sources on a horizontal plane;
because the illumination light sources are in fan-shaped arrangement, a certain included angle is formed between the illumination light sources. In the step, after the illumination light sources are projected onto the horizontal plane, the included angle of the projection of two adjacent illumination light sources on the horizontal plane is used as the included angle of the two adjacent illumination light sources on the horizontal plane.
S237B: and determining the annular area of the personnel travelling between two adjacent process sections according to the color temperature adaptation time and the included angle of the two illumination light sources on the horizontal plane.
Different annular areas correspond to different advancing times, and the time for adapting to the color temperature difference in the advancing process of a person can be controlled by selecting a specific annular area, so that the field staff can adapt to the influence caused by the color temperature difference before advancing to the irradiation area of the next illumination light source.
As an alternative but advantageous embodiment, the step S237B: determining the annular region traveled by a person between two adjacent process segments according to the color temperature adaptation time and the angle between two adjacent illumination sources on the horizontal plane further comprises the steps of:
s2371: acquiring a personnel reference travelling speed;
the person reference travel speed may be set empirically and typically may choose to be somewhat faster than walking.
S2372: the travel distance S required to accommodate the color temperature difference is calculated from the person reference travel speed and the color temperature adaptation time.
Let the person reference travel speed be V, the travel distance s=v×time.
S2373: determining an inner arc length LI and an outer arc length LO of the annular region according to the travel distance required for adapting to the color temperature difference, wherein S is smaller than LI and smaller than LO;
the medial arc length LI may be determined first in practice, and may be empirically set when shorter than the travel distance is desired. When the inner arc length is determined, the outer arc length can be obtained by adding the redundancy value of the arc length on the basis of the inner arc length, and the redundancy value can be set according to experience.
S2374: determining a starting point position and an ending point position of the annular region in the length direction of the illumination light source according to the inner arc length and the outer arc length;
and setting an included angle between the illumination light sources as gamma, wherein gamma is an angle of radian, wherein the radius corresponding to the inner arc length is RI=LI/gamma, the radius corresponding to the outer arc length is RO=LO/gamma, the center of the fan shape is taken as a reference point, and the position away from the reference point along the length direction of the first illumination light source is taken as an end position.
S2375: and determining the annular region where people travel between two adjacent process sections according to the inner arc length and the outer arc length of the starting point position and the end point position.
In the specific implementation, the illumination area of the illumination light source can be divided into a plurality of circular rings with different radiuses, each circular ring is numbered, then the on-site personnel are prompted according to the circular ring where the determined circular ring area is located, and the on-site personnel are informed of the number of the circular ring where the circular ring area is located in a video or voice mode.
The field staff can travel in the annular area determined by the method, so that the field staff can quickly pass through the area with gradient change of the color temperature, and the field staff can fully adapt to the difference of the color temperature in the traveling process.
The invention can also utilize the natural light source to illuminate the production site, and adjust the brightness of the illumination light source according to the brightness of the natural light source, thereby ensuring that the illumination effect of the production site meets the generation requirement and saving energy.
