The work management system 1 of the present invention is working by acquiring the biological information of the worker and setting the work that the worker can perform at the present time based on the health condition of the worker grasped from the biological information. The purpose is to prevent serious accidents caused by work mistakes due to changes in physical condition, and to carry out work efficiently without delay due to excessive work restrictions.

[Embodiment 1]
First, the work management system 1 of the first embodiment according to the present invention will be described.

<Structure of Embodiment 1>
As shown in FIG. 1, the work management system 1 of the first embodiment includes a work management unit 10, a biological information acquisition unit 20, and an environmental information acquisition unit 30.

As a hardware configuration, the work management unit 10 includes a processor that realizes a predetermined function by executing a program, and a plurality of peripheral devices (input unit 10a, display unit 10b, communication unit) connected to the processor via a bus. The functions of each part are realized by a terminal device such as a PC (Personal Computer) equipped with (10c, etc.).

The input unit 10a is composed of an input device such as a mouse or a keyboard. The display unit 10b is composed of a display device such as an LCD (Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display. The communication unit 10c is composed of a network interface that controls wired or wireless communication with another device via a communication network NW according to a predetermined protocol.

As shown in FIG. 1, the work management unit 10 includes a physical condition determination unit 11, a health condition determination unit 12, a work selection unit 13, and a work setting unit 14. The functions of the physical condition determination unit 11, the health condition determination unit 12, the work selection unit 13, and the work setting unit 14 are realized by the control unit 15 composed of various processors such as a CPU, ROM, and RAM. .. In addition, the work management unit 10 includes a storage unit 16, and the physical condition determination unit 11 and the health condition determination unit 12 determine the current state (physical condition and health condition) of the worker. To be equipped with.

The physical condition determination unit 11 determines the current physical condition of the worker based on the biological information of the worker acquired by the biological information acquisition unit 20, and acquires the physical condition information indicating the determination result. The physical condition information is an index value indicating the current physical condition of the worker, and is set based on the biological information acquired by the biological information acquisition unit 20. Since the physical condition information is acquired along with the input of the biological information, the physical condition information is sequentially acquired while the worker is performing the work, and is output to the health condition determination unit 12.

For example, the physical condition information is based on the biological information (body temperature, blood pressure, pulse rate, respiratory rate) when the health condition is good, and the evaluation result is based on whether the biological information value is higher or lower than the corresponding reference value. It is also possible to set a predetermined index value based on this.

The work shown at this time is an act performed by the worker to obtain a predetermined result by moving the whole body or a part of the body (hands, feet, etc.), as well as an act of determining whether or not there is an execution instruction of this act. It includes. That is, the work includes not only the work performed using the body but also the work performed using the brain.

One example is work in a gas supply facility.
After receiving a liquid gas tanker that carries liquid gas, this gas supply facility stores this liquid gas in a tank, which is a storage, and produces gas from the liquid gas as needed and supplies it to the demand source. It is a facility.

At this gas supply facility, liquefied natural gas (LNG) composed of methane, ethane, etc., and liquefied petroleum gas (LPG) composed of propane, butane, etc. are transported by a liquid gas tanker. In this case, the unloading arm of the receiving facility provided at the berth of the ship sucks up these liquefied gases (liquefied natural gas and liquefied petroleum gas) and stores them in a storage (LNG tank, LPG tank).

The gas supply facility is provided with a control system consisting of one or more control devices, each of which is a pump provided within the facility (specifically, a "gas production facility"). By controlling equipment such as vaporizers and heat conditioners, it is possible to manufacture and supply gas (natural gas), which is an energy substance, from raw materials that are liquefied gas (liquefied natural gas and liquefied petroleum gas) stored in storage. Manage and control.

In this control device 300, liquefied natural gas and liquefied petroleum gas stored in storage (LNG tank, LPG tank) are sucked up by a pump, and these liquefied gas is passed through a vaporizer (vaporizer) through a pipe. , Return this liquefied natural gas or liquefied petroleum gas to gaseous natural gas. Then, the heat control device adjusts the amount of heat that differs depending on the components constituting the natural gas. Through such processing, the control system will produce and supply the necessary natural gas.

Of course, in this control system, in addition to these devices, many other devices are controlled by the control device to stably produce and supply gas.

For example, in this control system, the boil-off gas generated in the LNG tank or the LPG tank is sucked by a gas compressor (BOG compressor), and the boil-off gas is sent to the reliquefaction device.

Then, in this reliquefaction device, the boil-off gas is reliquefied, and the reliquefied liquefied gas is passed through the vaporizer. The natural gas produced by being returned to gas by this vaporizer is temporarily stored in a hangar called a holder, and if necessary, the odorant is deodorized by the gas and supplied to the demand source. At this time, the required pressure (high pressure, medium pressure, low pressure) is adjusted through a plurality of governors provided in various places, and the required amount of gas is supplied through the piping by adjusting various adjusting valves. ..

As the work performed by the worker in the gas supply facility as shown above, each control device is instructed to execute the process performed by each control device. In addition, a wide range of work such as the work of actually opening the regulating valve, the work of inspecting gas leaks at the gas supply facility, and the work of cleaning are applicable.

Subsequently, the health condition determination unit 12 shown in FIG. 1 is the current health condition of the worker based on the physical condition information input from the physical condition determination unit 11 and the reference physical condition information stored in the storage unit 16. And acquire health condition information showing the judgment result. Since the health condition information is acquired along with the input of the physical condition information, it is sequentially acquired while the worker is performing the work and is output to the work selection unit 13.

The health condition information is an index value indicating the current health condition of the worker, which is set based on the result of comparing the physical condition information and the reference physical condition information. The health condition information is, for example, a difference value between the index value of the physical condition information and the index value of the reference physical condition information.

Since the good physical condition of a worker differs from worker to worker, the index value of the standard physical condition information to be set also naturally differs from worker to worker. That is, the health condition information indicating the health condition of the worker is the information set for each worker by the physical condition information of the individual worker and the standard physical condition information of the individual worker.

The work selection unit 13 uses the health condition information input from the health condition determination unit 12, the worker information of the corresponding worker in the worker information database, and the work environment information input from the environment information acquisition unit 30. Based on this, among the tasks that the worker is in charge of, the tasks that can be performed in the current health condition of the worker are selected. The work selection unit 13 outputs work selection information indicating the selected work to the work setting unit 14.

When selecting a work, the work selection unit 13 collates the work environment information acquired by the environment information acquisition unit 30 with the environmental impact data stored in the storage unit 16 to create a work environment for each work site. Know how much it will affect the work, and make a comprehensive judgment including the degree of influence of the work environment on this work, the health condition information of the workers, and the worker information of the workers. This makes it possible to appropriately select the work that can be performed in the current health condition of the worker.

In addition, the work selection unit 13 selects work that can be performed by the worker in the current health state each time the health state information is input from the health state determination unit 12. Since the work selection unit 13 grasps the health condition of the worker while the worker is working, when it is detected that a predetermined change has occurred in the health condition of the worker, the worker Reselect the work that can be performed in the current state of health, and change the work from the previously selected work. When the selected work is changed, the work selection unit 13 outputs the work selection information after the selection change to the work setting unit 14.

The work selection unit 13 reselects the currently set work when the health condition of the worker has not changed to the extent that the work needs to be changed. That is, work changes are made only when it becomes difficult for the worker to perform the current work.

The work setting unit 14 sets the work to be performed by the worker based on the work selection information selected by the work selection unit 13. The work setting unit 14 notifies a predetermined notification destination of the execution work information indicating the set work. The notification destination is, for example, an external terminal 100 such as a management server operated by an observer or a mobile terminal possessed by an observer or a worker.

In addition, when the work is changed from the initially set work due to the change in the health condition of the worker, the work setting unit 14 includes the work change information indicating that the work has been changed, as well as the changed execution work information. It is also possible to notify the observer and the like at the same time. As a result, the observer can simultaneously grasp that the work contents of the worker have been changed and the changed work contents at the same time. Can encourage changes to work.

The storage unit 16 is composed of a storage device such as a flash memory or an HDD (Hard Disk Drive), for example. The storage unit 16 contains various programs executed by the work management system 1, a worker information database that summarizes work ability information for each worker, and standard physical condition information used when determining the health condition of the worker. Various information necessary for operating the work management system 1 such as work influence degree data used for knowing the influence degree on work in the work environment is stored.

The worker information database is a data group in which worker information including work ability information indicating the work ability of each worker such as the age and work skill level of the worker is associated with each worker. The work ability information is an index value indicating the work skill level set in consideration of the number of years of service, the experience record for the work such as the number of years of experience of each work, and the strength / weakness of the work.

For example, in the case of a worker who has 15 years of service and 2 years of work experience and a worker who has 10 years of service and 7 years of experience, the latter has a higher work skill level. Work capacity information is set high. In addition, since the work ability information also considers the strengths and weaknesses of the work, even if the workers have the same work experience and years of service, the value of the work ability information may differ depending on the work content. There is also.

The reference physical condition information is an index value indicating the good physical condition of the worker, and is set in consideration of the work environment (environmental factors such as season, weather, temperature, humidity, etc.) of the work site during the work time zone. The reference physical condition information is set based on the biological information when the worker's health condition is checked in advance with the biological information and the biological information when the worker is in a good health condition and the work environment information in the working time zone.

The environmental impact data is an index value indicating the impact of the work environment on the work. When the index value of the environmental impact data is low, it is unlikely to affect the work and it is unlikely to interfere with the work execution, and when the index value of the environmental impact data is high, it is highly likely to affect the work. Indicates that it tends to interfere with performance. For the environmental impact data, the index value according to the impact of work is determined from the combination of "season", "weather", "temperature", and "humidity" which are environmental elements.

-season-
For the seasons, index values are set for each of the four seasons (spring, summer, autumn, and winter). For example, the seasonal index value is set to have a higher degree of influence on work in "winter" than in "spring".
-weather-
For the weather, for example, index values are set for each of the four states of "fine", "cloudy", "rain", and "snow". As for the index value of the weather, for example, "snow" is set to have a higher degree of influence on the work than "fine".
-temperature-
For the air temperature, an index value indicating the degree of influence on the work is set every 1 ° C. or every predetermined temperature range. As an example of the temperature range, for example, "5 ° C or lower", "6 ° C to 10 ° C", "11 ° C to 15 ° C", "16 ° C to 20 ° C", "21 ° C to 25 ° C", "26 ° C to 30". Set in 5 ° C increments such as "° C", "31 ° C to 35 ° C", and "35 ° C or higher".
-Humidity-
For humidity (relative humidity), an index value indicating the degree of influence on work is set every 1% or every predetermined humidity range. As an example of the humidity range, for example, "20% or less", "21% -40%", "41% -60%", "61% -80%", "81% or more" in 20% increments. Set the index value.

The environmental impact data shows the degree of impact on the work of work environment A, for example, when the season is "spring", the weather is "fine", the temperature is "20 ° C", and the humidity is "40%", and the season is "". Comparing the degree of influence on the work of work environment B of "winter", the weather of "snow", the temperature of "2 ° C", and the humidity of "50%", the degree of influence of work environment B is higher than that of work environment A. Since it becomes high, the index value is naturally set high.

The biological information acquisition unit 20 monitors the biological information of the worker. The biological information acquisition unit 20 is various sensors capable of acquiring the biological information of the worker, and can be configured by, for example, a wearable device worn on a part of the worker's body. When the biological information acquisition unit 20 acquires the biological information of the worker, it outputs it to the physical condition determination unit 11.

In the first embodiment, the biological information has four types of body temperature, blood pressure, pulse rate, and respiratory rate, but it is also possible to include biological information other than these. The biometric information may include at least one biometric information that can grasp the health condition of the worker.

The biometric information acquisition unit 20 of the first embodiment is configured to constantly acquire the biometric information of the worker who is working at least during the working time zone, but the acquisition timing is the health state of the worker during the working time zone of the worker. It is also possible to have a configuration in which changes in the above are acquired at predetermined intervals (for example, 1 minute intervals) that can be known.

The environmental information acquisition unit 30 acquires work environment information indicating environmental elements (season, weather, temperature, humidity, etc.) of the work site during the work time zone in which the work is performed. The environment information acquisition unit 30 outputs the acquired work environment information to the work selection unit 13.

The work site is a place where workers work, and there are many outdoors and indoors depending on the work content. Therefore, the environment information acquisition unit 30 may be configured to be able to acquire work environment information for each site where the work is performed. The environmental information acquisition unit 30 can also detect information on temperature and humidity with a sensor such as a thermo-hygrometer installed at the work site. Further, the information on the season and the weather can be detected by using, for example, a rainfall sensor, a snowfall sensor, and a sunshine sensor, or the information provided by a public institution or the like may be acquired.

<Processing operation of the first embodiment>
Next, the operation of the work selection process in the work management system 1 of the first embodiment will be described with reference to FIG. The operations described below are presented with step elements in an exemplary order, and are not limited to the specific order in which they are presented. Therefore, as long as there is no contradiction in the processing results of the flowchart shown in FIG. 2, the order can be changed.

As shown in FIG. 2, the biological information acquisition unit 20 first acquires the biological information of the worker, and outputs the acquired biological information to the physical condition determination unit 11 (ST1). The physical condition determination unit 11 acquires physical condition information indicating the current physical condition of the worker based on the input biological information, and outputs the acquired physical condition information to the health condition determination unit 12 (ST2).

The health condition determination unit 12 compares the input physical condition information with the reference physical condition information stored in the storage unit 16 to acquire the health condition information indicating the current health condition of the worker, and has acquired the health condition information. The health condition information is output to the work selection unit 13 (ST3).

Next, when the environment information acquisition unit 30 acquires the work environment information of each work site, it outputs the acquired work environment information to the work selection unit 13 (ST4). The work selection unit 13 includes the input health condition information, the worker information of the corresponding worker in the environmental impact data and the worker information database stored in the storage unit 16, and the work site in charge of the worker. The work that can be performed by the worker is selected based on the work environment information for each work, and the work selection information indicating the selected work is output to the work setting unit 14 (ST5).

In ST5, the work environment information for each work site is collated with the environmental impact degree data stored in the storage unit 16, and the degree of influence of the work environment on the work is known for each work site. Then, while considering the degree of influence of the work environment, the work that can be performed by the worker is comprehensively judged based on the health condition and work ability of the worker, and the work is selected.

Next, the work setting unit 14 sets the work to be performed by the worker based on the work selection information (ST6), and notifies the notification destination such as the worker or the observer of the work information indicating the set work. (ST7). When the execution work information is notified, it is determined whether or not a predetermined change has occurred in the health condition of the worker (ST8).

In ST8, if a predetermined change occurs in the health condition of the worker (ST8-Yes), it is determined that the work needs to be reselected (ST9), and the process returns to ST2 and is acquired by the biological information acquisition unit 20. The current physical condition information of the worker based on the new biological information is acquired, and the work selection process is performed according to the physical condition information.

On the other hand, when a predetermined change has not occurred in the health condition of the worker (ST8-No), it is determined whether or not the work in charge of the worker has been completed (ST10).

In ST10, when the work in charge of the worker is completed (ST10-Yes), the process is terminated.

On the other hand, if the work in charge of the worker is not completed (ST10-No), the process returns to ST8 again to determine whether or not the current health condition of the worker has changed.

<Action and effect of embodiment 1>
As described above, the work management system 1 of the first embodiment described above acquires the biological information of the worker, and acquires the physical condition information indicating the current physical condition of the worker from the biological information. Next, based on the acquired physical condition information and the standard physical condition information of the worker, the health condition information indicating the current health condition of the worker is acquired, and this health condition information and the worker information of the worker are used. , Select the work that the worker can currently perform based on the work environment information for each work site. Then, the selected work is notified to the notification destinations such as workers and observers.

The work is not stopped depending on the health condition of the person, and the work can be carried out efficiently.

Further, since the work management system 1 of the first embodiment sequentially monitors changes in the health condition of the worker during the work, if the health condition of the worker changes and the physical condition deteriorates, the work is immediately performed. It can be changed, and when the physical condition is recovered, the work can be shifted to the work that has been restricted until now, and the decrease in work efficiency can be suppressed.

[Embodiment 2]
Next, the work management system 1 of the second embodiment according to the present invention will be described.
In the work management system 1 of the second embodiment, the same configurations as the work management system 1 of the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and different configurations and processing functions will be mainly described.

<Structure of Embodiment 2>
In the work management system 1 of the second embodiment, a new function of determining whether or not the worker is performing the work according to the work selected in the first embodiment is newly added.

In order to realize this function, in the work management system 1 of the second embodiment, as shown in FIG. 3, a motion detection unit 40 for detecting the action range and the action content of the worker is added. Further, as shown in FIG. 3, the work management unit 10 has a motion analysis unit 18 that analyzes information about the motion content during work detected by the motion detection unit 40, and a motion analysis unit 18 based on the analysis results of the motion analysis unit 18. A work content determination unit 19 for determining whether or not the worker is performing the set work is added.

Further, the storage unit 16 of the second embodiment stores basic operation pattern information for each work for determining whether or not the work performed by the worker is a set work. The basic operation pattern information is information indicating a basic operation procedure according to a work procedure and an operation pattern at the time of work when a worker performs a certain work, and is set for each work content. The basic motion pattern information includes a feature motion pattern that extracts only characteristic motions in the work, in addition to an overall motion pattern that indicates the motion of the entire work.

The motion analysis unit 18 analyzes the action range and motion pattern of the worker from the motion analysis information including the position information and the motion information detected by the motion detection unit 40, and determines the work content using the analysis result as the motion analysis information. Output to unit 19. The motion analysis process includes a motion pattern of the work currently being performed by the worker from the motion analysis information detected by the motion detection unit 40 (an overall motion pattern in the task and a feature motion pattern showing a characteristic motion in the task). ) Is analyzed, and motion analysis information including these motion patterns is acquired as the analysis result.

The work content determination unit 19 is based on work selection information indicating the work selected by the work selection unit 13, motion analysis information input from the motion analysis unit 18, and basic motion pattern information stored in the storage section 16. , It is determined whether or not the work currently being performed by the worker is a set work. The work content determination unit 19 grasps the work content that the worker should currently perform from the implementation work information indicating the work selected by the work selection unit 13, but it is sufficient if the set work content can be grasped. For example, it is also possible to use the execution work information set by the work setting unit 14.

The work content determination unit 19 first confirms the work content from the work selection information selected by the work selection unit 13. Next, the work content determination unit 19 collates the work content with the basic operation pattern information corresponding to the set work stored in the storage unit 16 and the operation analysis information input from the operation analysis unit 18. , Determine whether the worker is performing the set work. The work content determination unit 19 outputs predetermined notification information based on the determination result to the external terminal 100.

The work content determination method is set when the matching ratio (match rate) between the preset basic motion pattern and the motion pattern included in the motion analysis information analyzed by the motion analysis unit 18 is equal to or greater than a predetermined rate. It is also possible to determine that the work done has been done. In addition, the validity of the work content is determined by the match rate between the overall motion pattern included in the motion analysis information and the overall motion pattern included in the basic motion pattern information, or the feature motion pattern and the basic motion pattern information included in the motion analysis information. At least one of the matching rates with the included feature motion patterns may be evaluated.

The notification information from the work content determination unit 19 may include information that notifies the worker and prompts the worker to stop the work. In addition, the notification information may include information prompting the user to change from the work currently being performed to the work that should be performed originally. Further, the notification information to the observer can include information indicating that the worker is performing a work different from the set work.

The motion detection unit 40 detects the position information indicating the action range of the worker and the motion information corresponding to the motion during the work. When the motion detection unit 40 detects the position information and the motion information of the worker, the motion detection unit 40 outputs these information to the motion analysis unit 18 as motion analysis information.

The motion detection unit 40 is composed of, for example, a wearable device worn on a part of the worker's body. Wearable devices include, for example, an accelerometer (for example, a three-axis accelerometer capable of measuring linear acceleration in three directions of the X-axis, Y-axis, and Z-axis) and an angular velocity sensor (for example, three of the X-axis, Y-axis, and Z-axis). It is also possible to mount various sensors such as a 3-axis gyro sensor that can measure the rotational angular velocity in the direction, and detect motion information indicating the behavior (movement content) of the worker's body movement over time from the output of these sensors. It is possible.

Further, the motion detection unit 40 can mount a position sensor such as GPS (Global Positioning System) on the wearable device, and can detect the position information during work from the output of the sensor over time.

<Processing operation of the second embodiment>
Next, the operation of the work determination process in the work management system 1 of the second embodiment will be described with reference to FIG. The operations described below are presented with step elements in an exemplary order, and are not limited to the specific order in which they are presented. Therefore, as long as there is no contradiction in the processing results of the flowchart shown in FIG. 4, the order can be changed.

First, the motion detection unit 40 detects the position information indicating the work position of the worker and the motion information indicating the motion content during the work, and outputs these information to the motion analysis unit 18 as motion analysis information (ST21). ). The motion analysis unit 18 analyzes the motion pattern according to the work currently being performed by the worker using the motion analysis information from the motion detection unit 40, and the motion analysis information indicating the analysis result is used as the work content determination unit. Output to 19 (ST22).

The work content determination unit 19 uses the work selection information input from the work selection unit 13, the motion analysis information input from the motion analysis unit 18, and the basic motion pattern information stored in the storage unit 16. It is determined whether or not the work currently being performed by the member matches the set work (ST23).

In ST23, if the work currently being performed by the worker matches the set work (ST23-Yes), it is determined that the work set by the worker is being performed, and the process is terminated.

On the other hand, if the work currently being performed by the worker does not match the set work (ST23-No), it is determined that the worker is performing work other than the set work. Then, the work content determination unit 19 notifies the notification destinations such as the worker and the observer of the predetermined notification information (ST24), and ends the process. The notification information includes, for example, a notification prompting the user to stop the work, a notification prompting the change to the set work, and the like.

<Action and effect of embodiment 2>
As described above, the work management system 1 of the second embodiment analyzes the motion pattern related to the work currently being performed by the worker from the motion analysis information from the motion detection unit 40, and uses the analysis result as the motion analysis information. get. The work content determination unit 19 performs the work set by the worker using the operation analysis information, the work selection information input from the work selection unit 13, and the basic operation pattern information stored in the storage unit 16. Whether or not it is determined. Then, when the work content determination unit 19 determines that the set work is not being performed as a result of the determination, the work content determination unit 19 notifies the worker or the observer of predetermined notification information such as a notification prompting the cancellation or change of the work. ..

For example, when a worker performs work other than the set work, there is a risk of causing a work mistake due to a sudden change in physical condition, and the work mistake may lead to a serious accident. However, in the work management system 1 of the second embodiment, it is possible to grasp whether or not the worker is performing work other than the set work, and even if different work is performed, the work is promptly performed before a work error occurs. Since it is possible to cancel or change the work contents, it is possible to prevent accidents due to work mistakes.
