Description

  The present invention relates to a work environment control system, a work environment control method, and a work environment control program for controlling a work environment for an operator to perform various works.

Accordingly, as indicated by the dotted line in FIG. 6, when the arousal level on the horizontal axis of the graph of FIG. 4 is specified, the illuminance on the horizontal axis of the graph of FIG. Will be specified. Similarly, although illustration of details is omitted, the vertical axis of the other graph shown in FIG. 5 is also shown on the same scale as the vertical axis of the graph of FIG. Thus, the temperature and humidity are uniquely specified. In this embodiment, psychophysiological correlation information and physiological environment correlation information are described separately. However, both may be integrated around the same vertical axis as psychophysiological environment correlation information.

  The biorhythm environment DB 15d of FIG. 2 is a biorhythm environment information storage unit that stores information (biological rhythm environment information) for specifying a work environment at each time according to the biorhythm of the worker. For example, as shown in FIG. 7, this biological rhythm environment information is configured as a different graph for each of a plurality of environment types. Each graph is a graph in which the horizontal axis represents time and the vertical axis represents a numerical value corresponding to each environmental target. For example, the graph shown in the forefront in the example of FIG. 7 is a graph of environmental target = illuminance, and the numerical value on the vertical axis = illuminance. In other words, this graph data shows a change in illuminance according to time, and an ideal change in illuminance in order to properly adjust the biological rhythm of the worker. Similarly, although the detailed illustration is omitted, in the graph of environmental target = temperature, the numerical value of the vertical axis = temperature, which is a change in temperature according to time, in order to properly adjust the biological rhythm of the worker It shows the ideal temperature change. In addition, the graph data of environmental target = humidity is the numerical value on the vertical axis = humidity, and shows the change in humidity according to the time, which is ideal for properly adjusting the biological rhythm of the worker. ing.

  The physiological normality determination table 15e of FIG. 2 stores physiological normality correlation information storage means for storing information (physiological normality correlation information) for specifying the correlation between the physiological state of the worker and the physiological normality of the worker. It is. For example, as shown in FIG. 8, the physiological normality correlation information includes a numerical range that can be taken by a physiological target (here, an electrocardiogram HF) set by the physiological target setting unit 16 b and the operator's physiological corresponding to the numerical range. Normal degree of normality (here, three levels of abnormality, caution, and normal) are associated with each other.

  The information stored in each of the DBs 15a to 15d and the table 15e in FIG. 2 is preliminarily system-managed based on, for example, academic papers on known psychology, physiology, work environment, biological rhythms, data obtained through experiments, and the like. Stored in each DB. In particular, the information stored in each of the DBs 15a to 15d stores data personalized for each worker, and is stored in association with a worker ID for uniquely identifying the worker. The specific configuration of the storage unit 15 is arbitrary, and can be configured using rewritable recording means such as HD (Hard Disk).

(processing)
Next, processing executed in the work environment control system 1 will be described. 9 and 10 are flowcharts of the work environment control process in the work environment control system 1. It should be noted that the control unit 14 of the work environment control server 10 performs control that is not specified. Step is abbreviated as “S”.

  First, when an operator enters the work room, the work environment control process is automatically started. After entering the room, the operator selects the work type of the work he / she performs in the terminal device 5. Although the specific method of this selection is arbitrary, for example, it is performed by displaying a list of work types on a monitor (not shown) provided in the terminal device 5 and selecting a desired work type from the list. In the following description, it is assumed that work type = office paperwork processing is selected.

  After the work type is selected in this way (SA1, Yes), the worker sets the work amount of the work he / she performs in the terminal device 5. Although the specific method of this setting is arbitrary, for example, the control unit 14 causes the monitor (not shown) provided in the terminal device 5 to display a work amount setting frame that matches the work type selected in SA1, and this setting is performed. This is done by setting a desired work amount on the frame. In the following description, it is assumed that the amount of work = the number of processes per unit time = 10 is input.

  When the work amount is selected in this way (SA2, Yes), the psychological target setting unit 16a of the goal setting unit 16 determines these based on the work type selected in SA1 and the work amount set in SA2. A psychological target corresponding to the work target specified by the work type and the work amount is set with reference to the work psychological correlation information stored in the work psychological correlation DB 15a (SA3). Specifically, the psychological target setting unit 16a corresponds to the work type (here, paperwork processing) selected in SA1 from different graph data stored in the work psychology correlation DB 15a for each of the work types. A graph to be selected is selected, and the selected graph is referred to, and the arousal level that is a physiological target corresponding to the work amount (here, 10 cases) set in SA2 is specified. Note that the work psychological correlation information stored in association with the worker ID of the worker is used as the work psychological correlation information referred to at this time. The identification of the worker ID is arbitrary. For example, the worker ID stored in advance in an ID tag (not shown) held by the worker is read by a tag reader (not shown) and transmitted to the work environment control server 10, or This is performed by the worker inputting his / her worker ID to the terminal device 5 (the identification of such a worker ID and the acquisition of information associated with the worker ID from the storage unit 15 are as follows. The same applies to information acquisition from the unit 15).

  Next, the physiological target setting unit 16b of the target setting unit 16 sets a physiological target that is a physiological state corresponding to the psychological target set in SA3 with reference to the psychophysiological correlation information stored in the psychophysiological correlation DB 15b. (SA4). Specifically, the physiological target setting unit 16b refers to a graph stored in the psychophysiological correlation DB 15b, and specifies an electrocardiogram HF that is a psychological target corresponding to the arousal level set by the psychological target setting unit 16a.

  Next, the environmental target setting unit 16c of the target setting unit 16 sets an environmental target that is a work environment corresponding to the physiological target set in SA4 with reference to physiological environment correlation information stored in the physiological environment correlation DB 15c. (SA5). Specifically, the environmental target setting unit 16c refers to each of the different graphs stored in the physiological environment correlation DB 15c for each type of environment, and corresponds to the electrocardiogram HF set by the physiological target setting unit 16b. Identify target illuminance, temperature, and humidity.

  After that, the device control unit 17 controls the environment control device for adjusting the work environment based on the environmental target set in SA5 (SA6). Specifically, the device control unit 17 generates a control signal in a predetermined format including the illuminance set by the environmental target setting unit 16c, and transmits the generated control signal to the lighting device 6. The lighting device 6 that has received the control signal controls the illuminance of the lighting device 6 so as to match the illuminance included in the control signal. Thereafter, the illuminating device 6 maintains the illuminance in the work room at the illuminance set in SA5 by performing feedback control based on the monitoring result while monitoring the illuminance in the work room via an illuminance sensor (not shown). Thus, the lighting device 6 is controlled (SA7).

  In addition, the device control unit 17 generates a control signal in a predetermined format including the temperature and humidity set by the environmental target setting unit 16 c and transmits the generated control signal to the air conditioner 7. The air conditioner 7 that has received this control signal adjusts the temperature and humidity of the air conditioner 7 so as to match the temperature and humidity included in the control signal (SA8, SA10). Thereafter, the air conditioner 7 performs feedback control based on the monitoring result while monitoring the temperature and humidity in the work chamber via a temperature sensor and a humidity sensor (not shown), so that the temperature and humidity in the work chamber are SA5. The air conditioner 7 is controlled so as to be maintained at the set temperature and humidity (SA9, SA11). As a result, the environment of the working room is automatically adjusted according to the psychological goal that matches the work goal of the worker and the environmental goal corresponding to the physiological goal.

(Processing-biological rhythm adjustment processing)
Next, as shown in FIG. 10, a biological rhythm adjustment process is executed (SA12). This biological rhythm adjustment process is a process for adjusting the environmental target set by the environmental target setting unit 16c according to the time at that time with reference to the biological rhythm environment information stored in the biological rhythm environment DB 15d. . A flowchart of this biological rhythm adjustment process is shown in FIG.

  First, the biological rhythm adjustment unit 18 selects an environmental target (in this case, illuminance, in this case) corresponding to the current time obtained by a known method from different graphs stored in the biological rhythm environment DB 15d for each type of environment. Temperature and humidity) are acquired, and this environmental target is set as a reference value (SB1). Then, the biological rhythm adjustment unit 18 again returns a plurality of times stored in the biological rhythm environment DB 15d every time a predetermined time interval (for example, 30 minutes) elapses until the work environment control process ends (SB2, Yes). An environmental target (here, illuminance, temperature, and humidity) corresponding to the current time acquired by a known method is acquired from a graph that is different for each type of environment, and this environmental target is set to the current value ( SB3).

  The biological rhythm adjustment unit 18 obtains the ratio of the reference value to the current value every time the current value is set at predetermined time intervals (SB4), and the ratio is set in SA5 in FIG. A new environmental target is calculated by multiplying the target, and this environmental target is reset as an environmental target for optimizing the biological rhythm of the worker (SB5). And the apparatus control part 17 controls the apparatus for environmental control similarly to SA6-SA11 of FIG. 9 based on the environmental target reset by SB5. 9 and 10, for convenience, the biological rhythm adjustment process is shown only between the control of the environmental control device (SA6 to SA11) and the normality monitoring process (SA13) described later. As described above, setting of the current value, calculation of the ratio, setting of the environmental target, and the like are repeatedly performed every time a predetermined time interval elapses until the work environment control process is completed.

  For example, as shown in FIG. 7, the illuminance is maintained at about 2500 lx from 9 o'clock to 15 o'clock, and at a constant rate of about 700 lx at 18:00 from 15 o'clock to 18 o'clock. It is preferable to reduce the pressure and maintain about 700 lx after 18:00 in order to optimize the biological rhythm of the worker. Therefore, in this embodiment, the ratio of the illuminance change at each time is reflected in the work environment. Therefore, for example, after the environmental target is performed in SA5 in FIG. 9, when the time at which SB1 in FIG. 11 arrives is 10:00, the illuminance = 2500 lx is set as the reference value in SB1, Thereafter, until 15 o'clock, illuminance = 2500 lx is set as the current value every time SB3 is repeated at a predetermined time interval, and the ratio of the reference value to the current value = 1 (= 2500/2500) is obtained in SB4.

  Here, when the illuminance is 1800 lx, which is the environmental target set in SA5 of FIG. 9, the illuminance = 1800 lx is obtained as a multiplication result by multiplying the illuminance = 1800 by the ratio = 1 in SB5 of FIG. Then, the multiplication result is set to illuminance which is an environmental target for optimizing the biological rhythm of the worker. That is, in this example, the illuminance = 1800 lx, which is the environmental target set in SA5 of FIG. 9, is maintained from 10:00 to 15:00. Thereafter, when SB3 of FIG. 11 is performed between 15:00 and 18:00, the current value is set between illuminance = 2500 and 700 lx, and the ratio of the reference value to the current value in SB4 = 0.28 or more. Since it is less than 1 (= 2500 to 700/2500), in SB5, the illumination result = 1800lx, which is the environmental target set in SA5 of FIG. 9, is multiplied by the ratio = 0.28 or more to less than 1 to obtain the multiplication result. Illuminance = 1800 to 504 lx, and the multiplication result is set to illuminance which is an environmental target for optimizing the biological rhythm of the worker. This completes the biological rhythm adjustment process. By performing such biological rhythm adjustment processing, it is possible to perform environmental control that reflects changes in environmental targets for optimizing biological rhythms based on the environmental targets set in SA5 of FIG. Become.

(Process-normality monitoring process)
Thereafter, as shown in FIG. 10, normality monitoring processing is executed (SA13). This normality monitoring process is a process for correcting the environmental target set by the environmental target setting unit 16c based on the physiological normality of the worker or outputting guidance for the worker. A flowchart of the normality monitoring process is shown in FIG.

  First, in the working room, the sensor 2 outputs the physiological information of the worker corresponding to the physiological target (here, electrocardiographic data for calculating the electrocardiogram HF) to the receiver 3. The receiver 3 transmits the physiological information received from the sensor 2 to the work environment control server 10. When receiving the physiological information (SC1, Yes), the normality determination unit 19 of the work environment control server 10 determines the physiological normality of the worker based on the received physiological information. Specifically, the normality determination unit 19 calculates a physiological target (here, an electrocardiogram HF) from the physiological information, and the normality corresponding to the physiological target is stored in the physiological normality determination table 15e. The determination is made with reference to the correlation information (SC2).

  Next, the physiological state normalization unit 20 adjusts the environmental target set in SA5 of FIG. 9 or the environmental target in SA12 of FIG. 10 based on the physiological normality of the worker determined by the normality determination unit 19. If so, the adjusted environmental target (hereinafter, current environmental target) is corrected (SC3). Specifically, the physiological state normalization unit 20 maintains the current environmental target as it is when the normality determined by the normality determination unit 19 is normal, and the normal environmental target when the normality is caution. Is corrected by a predetermined method that reduces the physiological burden on the worker. When the normality = abnormal, the current environmental target is set, and the physiological burden on the worker is greater than when the normality = attention. Further, it is corrected by a predetermined method that is reduced. For example, when the normality = attention, the physiological state normalizing unit 20 decreases the illuminance at the current environmental target by a predetermined ratio (for example, 30%). Further, for example, when the normality = abnormal, the physiological state normalizing unit 20 sets the illuminance, temperature, and humidity in the current environmental target to predetermined values that the operator can most relax (for example, illuminance = 700 lx). , Temperature = 27 degrees, humidity = 50%). And the apparatus control part 17 controls the apparatus for environmental control similarly to SA6-SA11 of FIG. 9 based on the illumination intensity, temperature, and humidity which are the environmental targets reset in this way.

  The physiological state normalizing unit 20 outputs guidance for the worker based on the worker's physiological normality determined by the normality determining unit 19 (SC4). Specifically, the physiological state normalization unit 20 does not output guidance when the normality level determined by the normality level determination unit 19 is normal, but when the normality level is caution, the operator voluntarily A guidance voice (such as “Please slow down the work pace”) is output through the speaker 4 to encourage attention to health and relaxation. If the normality is abnormal, the worker A guidance voice for prompting the user to immediately stop and take a break (such as “stop work and take a break for 10 minutes”) is output via the speaker 4. This completes the normality monitoring process. By performing such normality monitoring processing, the environmental target can be corrected to an environmental target capable of maintaining the normality of the worker's physiology, and the physiological safety of the worker is ensured. Is possible.

(Processing-target correction processing)
Thereafter, the target correction process of FIG. 10 is executed (SA14 to SA21). First, when the worker feels discomfort during work (SA14, Yes), the type of discomfort and the degree of discomfort are input via the terminal device 5. Although the specific input method of these information is arbitrary, for example, a list of types of environments (in this case, illuminance, temperature, humidity) controlled by the environmental control device on a monitor (not shown) provided in the terminal device 5 And display a slide bar to input the degree of discomfort (or desired illuminance, temperature, humidity increase or decrease rate), select the desired environment type from this list, and Enter the degree of discomfort by sliding. The information inputted in this way is the terminal device 5 as environmental target correction information (comfort information for specifying the comfort felt by the worker) for correcting the environmental target set by the environmental target setting unit 16c. To the work environment control server 10.

  The environmental target correction unit 21d of the work environment control server 10 that has received this environmental target correction information via the input / output IF 11 sets in SA5 of FIG. 9 based on the environmental target correction information received via the input / output IF 11. If the environmental target is adjusted in SA12 of FIG. 10, the adjusted environmental target is adjusted, or if the environmental target is adjusted in SA13 of FIG. The current environmental target). For example, when the environment type = illuminance is selected by the operator and the degree of discomfort = 20% increase rate is input by the operator, the environmental target correction unit 21d determines the illuminance at the current environmental target. Increase illuminance by 20%. Similarly, the environmental target correction unit 21d also resets the temperature and humidity based on the environmental target correction information (SA15). Thereafter, the process proceeds to SA5 in FIG. 9, and the device control unit 17 sets the environment control device in the same manner as SA6 to SA11 in FIG. 9 based on the illuminance, temperature, and humidity that are the environmental targets reset as described above. To control. Thereafter, SA5 to SA15 are repeated until the worker does not feel uncomfortable. When the worker does not feel uncomfortable (SA14, No), the process proceeds to SA16.

  Thus, apart from the biological rhythm adjustment processing and normality monitoring processing, the target correction based on discomfort is performed even when an environment corresponding to the biological rhythm and an environment that maintains normality can be constructed. The subjective comfort of the worker may not always be high. In such a case, it is preferable to optimize the worker's work environment by changing the environment in consideration of the worker's subjectivity. It is because it is considered. Therefore, by performing such processing, it is possible to construct a work environment in which the worker feels subjectively comfortable.

  Next, in SA16, the physiological target correcting unit 21c determines whether the physiological target set in SA4 of FIG. 9 has been achieved based on the physiological target correction information received via the input / output IF 11 (SA16). ). That is, like the normality monitoring process, the electrocardiogram data received from the sensor 2 is continuously transmitted from the receiver 3 to the work environment control server 10 as physiological target correction information for correcting the physiological target. The physiological target correction unit 21c of the work environment control server 10 that has received the physiological target correction information via the input / output IF 11 is set based on the physiological target correction information received via the input / output IF 11 in SA4 of FIG. A physiological value (here, an electrocardiogram HF) that matches the physiological target is calculated. Then, the physiological target correcting unit 21c compares the calculated electrocardiogram HF with the physiological target set in SA4 (here, the electrocardiogram HF), and if the two do not match each other, the physiological target is not achieved. (SA16, No), the physiological target set in SA4 is feedback-controlled so that they are the same as each other (SA17). For example, when the calculated electrocardiogram HF is lower than the electrocardiogram HF set in SA4, the physiological target correction unit 21c resets an electrocardiogram HF higher than the electrocardiogram HF set in SA4 as a physiological target.

  Then, when the physiological target correcting unit 21c corrects the physiological target, the environmental target setting unit 16c sets the environmental target corresponding to the corrected physiological target in the same manner as SA5. Further, the device control unit 17 controls the environment control device in the same manner as SA6 to SA11 based on the environmental target set in this way. Thereafter, SA4 to SA17 are repeated until it is determined that the physiological target is achieved. If it is determined that the physiological target is achieved (SA16, Yes), the process proceeds to SA18. By performing such processing, it is possible to construct a work environment for achieving the set physiological target.

  Next, in SA18, the psychological target correcting unit 21b determines whether or not the psychological target set in SA3 of FIG. 9 has been achieved based on the psychological target correction information received via the input / output IF11 (SA18). ). That is, the worker periodically inputs his / her psychological state to the terminal device 5. Although the specific input method of this information is arbitrary, for example, on the monitor (not shown) provided in the terminal device 5, the character indicating the type of psychology (here, the arousal level) set in the psychological target, A slide bar for inputting the degree of the psychological state according to the type is displayed, and the degree of the psychological state is input by sliding the slide bar. Information input in this way is transmitted from the terminal device 5 to the work environment control server 10 as psychological target correction information for correcting the psychological target.

  The psychological target correction unit 21b of the work environment control server 10 that has received the psychological target correction information via the input / output IF 11 determines the degree of the psychological state specified by the psychological target correction information received via the input / output IF 11 (here Then, the degree of arousal) is compared with the psychological goal set in SA3 (here, the degree of arousal). If the two do not match each other, the psychological goal is not achieved (SA18, No). The psychological target set in SA3 is feedback-controlled so as to be the same as each other (SA19). For example, when the specified awakening level is lower than the awakening level set in SA3, the awakening level higher than the awakening level set in SA4 is reset as a psychological target.

  Then, when the psychological target correcting unit 21b corrects the psychological target, the physiological target setting unit 16b resets the physiological target corresponding to the corrected psychological target in the same manner as SA4. Further, when the physiological target correcting unit 21c resets the physiological target, the environmental target setting unit 16c resets the environmental target corresponding to the reset physiological target in the same manner as SA5. Furthermore, the device control unit 17 controls the environment control device in the same manner as SA6 to SA11 based on the environmental target reset as described above. Thereafter, SA3 to SA19 are repeated until it is determined that the psychological goal is achieved. If it is determined that the psychological goal is achieved (SA18, Yes), the process proceeds to SA20. By performing such processing, it is possible to construct a working environment for achieving the set psychological goal.

  Next, in SA20, the work target correction unit 21a determines whether or not the work targets set in SA1 and SA2 in FIG. 9 have been achieved based on the work target correction information received via the input / output IF 11. (SA20). That is, the worker periodically inputs his / her work state to the terminal device 5. The specific input method of this information is arbitrary. For example, on the monitor (not shown) provided in the terminal device 5, the work type selected in SA1, the character indicating the work amount set in SA2, and the current amount for the work amount Display a slide bar to input the degree of work (for example, the ratio of the number of processed items per unit time to the target number of processed items per unit time), and slide this slide bar to change the work status. input. Information input in this way is transmitted from the terminal device 5 to the work environment control server 10 as work target correction information for correcting the work target.

  The work target correction unit 21a of the work environment control server 10 that has received the work target correction information via the input / output IF 11 is a work amount that is a work state specified by the work target correction information received via the input / output IF 11. (Here, the number of processes per unit time) is compared with the amount of work set in SA2, and if the two do not match each other, it is assumed that the work target has not been achieved (SA20, No). The work targets set in SA1 and SA2 are feedback-controlled so that they are the same as each other (SA21). For example, when the number of processes per unit time specified is smaller than the number of processes per unit time set in SA2, the number of processes per unit time set in SA2 is set as the work amount that is the work target. Reset the number of processing per unit time that is larger than that.

  Then, when the work target is reset, the psychological target setting unit 16a resets the psychological target corresponding to the reset work target similarly to SA3. In addition, when the psychological target correcting unit 21b resets the psychological target, the physiological target setting unit 16b resets the physiological target corresponding to the corrected psychological target in the same manner as SA4. Further, when the physiological target correcting unit 21c resets the physiological target, the environmental target setting unit 16c resets the environmental target corresponding to the reset physiological target in the same manner as SA5. Furthermore, the device control unit 17 controls the environment control device in the same manner as SA6 to SA11 based on the environmental target reset as described above. Thereafter, SA2 to SA21 are repeated until it is determined that the work target has been achieved. If it is determined that the work target has been achieved (SA20, Yes), the process proceeds to a learning process of SA22. By performing such processing, it is possible to construct a work environment for achieving the set work goal.

(Processing-Learning process)
Finally, the learning process will be described (SA22). This learning process is stored in the work psychology correlation information stored in the work psychology correlation DB 15a, the psychophysiology correlation information stored in the psychophysiology correlation DB 15b, or the physiological environment correlation DB 15c, according to the correction result in the target correction process. This is a process for updating physiological environment correlation information. That is, when the environmental target, physiological target, psychological target, or work target is corrected in the target correction process, the corrected content is sequentially stored as correction history information in the storage unit 15, and the recorded correction history A learning process is executed based on the information. A flowchart of this learning process is shown in FIG.

  Specifically, the learning processing unit 22 calls the work target (work amount here) corrected in SA21 in FIG. 10 from the correction history information recorded in the storage unit 15 (SD1). By adding a plot that matches the work target and the psychological target (here, the arousal level) set when SA3 in FIG. 9 is first executed to the graph that is the work psychological correlation information of the work psychological correlation DB 15a. The work psychological correlation information is updated (SD2). The work psychological correlation information to be updated here is work psychological correlation information associated with the worker ID (the identification of the worker ID is performed by a method similar to the method described in relation to SA3 in FIG. 9). Hereinafter, regarding the update of the psychophysiological correlation information and the physiological environment correlation information, the information associated with the worker ID is similarly updated). Thereafter, when the psychological target is first set in SA3 in the subsequent work environment control processing, a regression curve that specifies the correlation between the work amount and the psychological target is recalculated, and the psychological target is referenced with reference to the regression curve. Is set, the work amount corrected in SA21 of FIG. 10 is reflected in the psychological target.

  Next, the learning processing unit 22 calls the psychological target (here, the arousal level) corrected in SA19 in FIG. 10 from the correction history information recorded in the storage unit 15 (SD3), and the called psychological target. Is added to the graph which is psychophysiological correlation information in the psychophysiological correlation DB 15b by adding a plot that matches the physiological target (here, the electrocardiogram HF) set when SA4 in FIG. 9 is first executed. The physiological correlation information is updated (SD4). Thereafter, when the physiological target is first set in SA4 in the next work environment control process, a regression curve that specifies the correlation between the psychological target and the physiological target is recalculated and obtained by referring to the regression curve. Is set, the psychological target corrected in SA19 of FIG. 10 is reflected in the physiological target.

  Next, the learning processing unit 22 calls (SD5) the physiological target corrected in SA17 in FIG. 10 (here, the electrocardiogram HF) from the correction history information recorded in the storage unit 15, and the called physiological target. And a plot that matches the environmental targets (here, illuminance, temperature, and humidity) set when SA5 in FIG. 9 is first executed is added to the graph that is physiological environment correlation information of the physiological environment correlation DB 15c. Thus, physiological environment correlation information is updated (SD6). Thereafter, when the environmental target is first set in SA5 in the next work environment control process, the regression curve for specifying the correlation between the physiological target and the environmental target is recalculated, and the environmental target is referenced with reference to the regression curve. Is set, the physiological target corrected in SA17 of FIG. 10 is reflected in the environmental target. This completes the learning process, and the work environment control process of FIGS. 9 and 10 ends.

(effect)
As described above, according to the present embodiment, the physiological target corresponding to the psychological target of the worker is automatically set, the environmental target corresponding to the physiological target is automatically set, and the environment target is set based on the environmental target. Since the control equipment is automatically controlled, it is an environment that corresponds to the psychological goal of the worker, and the worker performs the work in consideration of the correlation between the psychology and the physiology of the worker and the correlation between the physiology and the environment. It is possible to construct a work environment suitable for performing.

  In addition, a psychological target corresponding to the worker's work target is automatically set, and a physiological target corresponding to the psychological target is automatically set.

  In addition, since the environmental target is automatically corrected based on the physiological normality of the worker, it is possible to construct a working environment suitable for maintaining and improving the physiological normality of the worker. In addition, since guidance to the worker is automatically output based on the physiological normality of the worker, advice and caution for maintaining and improving the physiological normality of the worker are given to the worker. Can do.

  In addition, psychophysiological correlation information or physiological environment correlation information is automatically corrected according to the result of correcting the target. Therefore, the accuracy of these information can be improved every time the target is corrected, and the work environment can be improved. It can be constructed with higher accuracy.

The components of the work environment control system 1 described above are functionally conceptual, and need not be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured. For example, the terminal device 5 is provided with all or part of the functions of the work environment control server 10 or all or part of the functions of the work environment control server 10 in an ASP (Application Service Provider) format via an arbitrary network. May be provided.

(Control when multiple workers work)
In the present embodiment, a case where one worker performs work in one work room has been described. However, when a plurality of workers perform work in one work room, work environment control is similarly performed. Can do. For example, when the lighting device 6 and the air conditioner 7 can be individually controlled for each worker, the above-described work environment control can be performed for each worker. In addition, when the lighting device 6 and the air conditioner 7 cannot be individually controlled for each worker, the environmental goal corresponding to the work goal of each worker is individually identified and integrated based on these environmental goals. An environmental target may be calculated by a predetermined method (for example, an average value of illuminance for each worker is calculated as an integrated environmental target), and environmental control may be performed based on the integrated environmental target.

(About entering information about workers)
The information described as input by the worker may be input by a third party other than the worker (for example, an administrator who manages the worker), or automatically input by automatic detection by various sensors. May be. In the latter case, for example, instead of the worker inputting his / her work state, the amount of input information of the work result for the terminal device 5, the desk or chair used by the worker, or the input to the terminal device 5 Occasionally used keyboard vibration (acceleration measured by accelerometer), mouse acceleration and clicks used at the time of input to terminal device 5, enrollment rate, change rate of worker's head position, voice intermittent rate (especially work Or the like may be automatically acquired as a working state.

(About identification of worker's psychology)
Moreover, although the said embodiment demonstrated as what sets a psychological target automatically based on an operator's work target, you may make it an operator also set a psychological target. In this case, the operator may input a numerical value such as the degree of arousal to the terminal device 5, but the “awakening mode”, “relaxation mode”, “creativity mode”, “aggressive mode”, “paper processing mode” ”,“ Research mode ”, etc., a mode in which an operator selects one mode and the psychological target corresponding to the selected mode is stored in the storage unit 15 in advance. You may determine based on correlation information with a psychological target. For example, when “wake mode” is selected, the highest level of wakefulness (wake level = 10 in the example of FIG. 4) is set as a psychological target, and when “relax mode” is selected, the lowest level It is conceivable to set the arousal level (awakening level = 0 in the example of FIG. 4) as a psychological target. By selecting in such a mode, the operator can input a psychological target more easily and intuitively.

(Considering biological rhythm)
For example, the physiological environment correlation DB 15c may store, as physiological environment correlation information, a three-axis graph of a physiological target, an environmental target, and a time, which includes an environmental target that matches the biological rhythm. In this case, the environmental target setting unit 16c acquires an environmental target that corresponds to the physiological target and matches the current time from the physiological environment correlation DB 15c, and performs device control based on the acquired environmental target. The unit 17 may control the environment control device.
