Abstract
Description
Technical Field
[0001] The present invention relates to a work safety management system for managing the safety status of workers engaged in work including indoor work.
Background Art
[0002] Indoor facilities that require work centered on indoor work, such as factories, distribution centers, logistics centers, construction sites, large shopping malls, etc., exist in various locations. In these indoor facilities, workers mainly perform work indoors. Of course, they also work outdoors as well as indoors. However, although there is movement between indoors and outdoors, the work is often centered indoors.
[0003] In these indoor facilities, depending on their respective characteristics, the types and situations of indoor work by workers change.
[0004] For example, in a factory, workers perform indoor work in accordance with the production line and product movement routes. Depending on the type and location of the production line, or the type of product, etc., there are characteristics such as places and time zones where workers tend to concentrate, and changes in the movement routes of workers. Also, because it is a factory, distinctions such as working hours and break times are likely to be clearly defined. On the other hand, due to changes in the work content, etc., the times when workers start and end work in the indoor facility vary widely.
[0005] In indoor facilities such as distribution centers and logistics centers, workers often move to various places. Also, the ways of movement vary, and the movement routes of workers are very likely to become complex. Also, the movement between indoors and outdoors is likely to increase. Due to the complexity of the movement routes of each worker, workers may temporarily concentrate at a certain position or route. Also, like in factory work, the movement and work load of workers are large, and it is possible that the fatigue of workers increases.
[0006] In addition, in indoor facilities such as distribution centers and logistics centers, due to the heavy labor burden, workers may take frequent breaks and end up working outside of regular business hours. Also, going outside may also result in working outside of regular business hours. The same applies to large shopping malls and the like.
[0007] At construction sites and job sites, as construction and work progress, the structure of indoor facilities has the characteristic of changing. For example, at a building construction site, as the construction progresses, the number of floors increases, the areas are partitioned, and the structure changes three-dimensionally. Along with this structural change, the work content, movement routes, moving locations, workplaces, etc. of workers change. In addition, the number of workers at a certain workplace is also likely to fluctuate.
[0008] On the other hand, at construction sites and job sites as well, there are also many entries and exits between indoor facilities and the outdoors, including break times and interruption times. Similar to the work in other indoor facilities, workers may be engaged in work as a business indoors, and workers engaged in work as a business indoors may also be outside the indoor facility during non-business hours (before the start of business, after the end of business, break times). When they are outside like this, it is outside of regular business hours and is the private time of the workers.
[0009] Even in the state related to indoor work, there is private time as well as the case of being in the middle of indoor work.
[0010] Also, as described above, many workers are involved in various works in indoor facilities, and various changes and fluctuations occur in work content, movement routes, workplaces, density of people, work situations, etc. In addition, the structural changes of indoor facilities due to the characteristics of indoor facilities and the structural complexity, etc. are also added.
[0011] That is, in a wide variety of indoor facilities, many workers are engaged in various types of work, and the situation where it is difficult to grasp the work safety of these workers is increasing.
[0012] On the one hand, due to recent developments such as the labor shortage and the reform of working styles, there is an increasing demand for maintaining and managing the safety and health of workers. For example, in addition to preventing injuries and accidents to workers at construction sites and work sites, safety due to fatigue and the like is also being demanded.
[0013] This is the same even in cases such as when carrying heavy loads or using transportation equipment at distribution centers and logistics centers. This is because workers are exposed to physical burdens and risks due to the nature of the work and the characteristics of indoor facilities.
[0014] In addition, due to recent climate change, there are concerns about the risk of workers suffering from heat stroke and other symptoms during work. Or, there are concerns about problems of infectious diseases such as the novel coronavirus. That is, not only the safety of workers, but also the management and assurance of their health conditions are being demanded. This is the same not only at construction sites and distribution centers, but also at shopping malls and the like.
[0015] Several technologies for managing the safety and health of workers have been proposed (see, for example, Patent Documents 1, 2, 3, 4, and 5).

Summary of the Invention
Problems to be Solved by the Invention
[0017] Patent Document 1 discloses a health information management system in which, when a communication device 2 receives vital data from a measuring device 3, a string generation unit 21 that generates a first string and a second string according to a predetermined logic, a transmission unit 22 that associates the first string with the vital data and transmits it to a PHR data server 1 and transmits the second string to a user's mobile terminal 4. The PHR data server 1 includes a temporary registration unit 13 that temporarily registers by associating the first string sent from the communication device 2 with the vital data, a PHR service unit 11 that requests the user to input the second string at a service site, collates the input second string with the temporarily registered first string according to the above logic, and when the first string corresponding to the second string is obtained, a permanent registration unit 15 that associates the vital data associated with the first string with user information and registers it in a permanent registration vital DB 122.
[0018] Patent Document 1 discloses a technique for receiving vital data, which is an indicator of an operator's health status, and linking it with a server to perform health management of the operator. However, it has problems such as it being difficult to obtain the position information of an operator in an indoor facility. Also, since it relies on vital data, there is a problem that health management based on the working status of the operator cannot be performed.
[0019] Patent Document 2 discloses a safety management system 1 that includes a positioning device (GPS receiver 10) attached to a helmet 2 and measuring the position of the helmet. A terminal 3 communicably connected to the positioning device receives the position of the helmet measured by the positioning device and transmits a first warning signal when the position of the helmet is within a preset danger area 100. A warning generation device (alarm device 30) is attached to the helmet and communicably connected to the terminal, and discloses a safety management system that receives the first warning signal and generates a warning.
[0020] However, Patent Document 2 has the same problems as Patent Document 1. In addition, since it is based on the terminal attached to the helmet, there is also a problem that it is difficult to grasp the position indoors. Moreover, there is a problem that safety management based on the actions of workers such as work content, work status, and movement routes cannot be ensured reliably.
[0021] Patent Document 3 discloses a wearable sensor system having a first wearable sensor terminal 2 that acquires information related to cardiac function from a living body, a second wearable sensor terminal 3 that acquires information related to blood flow from the living body, and a determination device 1 that determines the state of the living body against heat stroke based on the information related to cardiac function acquired by the first wearable sensor terminal 2, the information related to blood flow acquired by the second wearable sensor terminal 3, and the information related to the temperature of the geographical position of the living body.
[0022] Patent Document 3 also has the same problems as Patent Documents 1 and 2. In addition, there is a problem that it is not possible to distinguish between private time when the worker is not at work and work time for safety management.
[0023] Patent Document 4 discloses a work analysis device including a coordinate information acquisition unit (5, 6) that detects the part coordinates and the existence position coordinates of the joint part of the worker, a work content extraction unit (9, 10) that extracts, as work content information, the procedure and movement route of the work operation and the time required therefor accompanying a series of works of the worker based on the part coordinates and the existence position coordinates acquired by the coordinate information acquisition unit (5, 6), a work content analysis unit (12) that analyzes the work content performed by the worker based on the work content information obtained by the work content extraction unit (9, 10) and determines the presence or absence of non-standard work deviating from the standard work, and a feedback unit (14) that prompts the worker to return to the standard work when it is determined by the work content analysis unit (12) that the work is non-standard work.
[0024] Patent Document 5 discloses an activity recording device (11) including a work specifying unit (12) that specifies the work of an operator (20), a position specifying unit (13) that specifies the position of the operator (20) from the position coordinates of the operator (20), a state specifying unit (14) that specifies the state of the work of the operator (20) from the position specified by the position specifying unit (13), and a recording unit (15) that records the work, position, and state as activity data in association with activity times, and further, the position specifying unit (13) includes a position estimating unit and a position correcting unit.
[0025] Patent Documents 4 and 5 also have the same problems as Patent Documents 1 to 3.
[0026] Among Patent Documents 1 to 5, there are also documents that disclose the collection of vital data. Alternatively, there are documents that disclose technologies for detecting the position information of workers. Combining these may lead to technologies for performing safety management of workers.
[0027] However, each of the prior arts and their combinations still leave the following problems in the safety management of workers.
[0028] (Problem 1) It is not possible to distinguish the private time before or after an operator starts or finishes indoor work and collect the position and health information of the operator. Therefore, consideration for the privacy of the operator is not possible.
[0029] (Problem 2) Safety management based on the movement routes and work routines of operators cannot be performed.
[0030] (Problem 3) When an abnormality occurs to an operator, it is not possible to notify the surrounding operators instead of the manager. Therefore, it is not possible to rescue the operator at an early stage.
[0031] Due to such problems, there has been a technical problem that safety management of operators including their health conditions is insufficient to cope with the structural characteristics of indoor facilities and the work characteristics of indoor work.
[0032] An object of the present invention is to provide a work safety management system that manages the health and safety of workers in accordance with the structural characteristics of indoor facilities and the work characteristics of indoor work.
Means for Solving the Problems
[0033] In view of the above problems, the work safety management system of the present invention includes a work state detection unit that detects that a worker is in a work state while working in an indoor facility, a position detection unit that receives the position information of a worker in an indoor facility based on a mobile terminal possessed by the worker and a communication device installed in the indoor facility, and detects the worker's position, a health information detection unit that receives the health index information of a worker transmitted from the mobile terminal and detects the worker's health information, a safety state determination unit that determines the safety state of the worker based on the worker's position detected by the position detection unit and the worker's health information detected by the health information detection unit, The position detection unit and the health information detection unit operate when the work state detection unit determines that the worker is in a work state, The communication device includes beacon terminals installed at multiple locations in the indoor facility. The position detection unit detects the position information of the worker based on the communication between the mobile terminal and the beacon terminal and the communication between the beacon terminal and the GPS signal, The position detection unit and the health information detection unit can ensure the privacy of the worker by operating only when the worker is in a work state, The safety state determination unit determines at least one of the normal state, health risk state, work abnormality state, accident occurrence state, and missing state of the worker, The determination result of the safety state determination unit is notify, and make a judgment on at least one of the normal state, health risk state, work abnormality state, and accident occurrence state of the worker further provided with a notification unit that notifies other workers (hereinafter, "surrounding workers") who are around the worker who is the subject of the safety state determination. When the safety state determination unit cannot detect the worker's position and the worker's health information of a certain worker, it determines that the mobile terminal possessed by the worker is not operating. judge
Effects of the Invention
[0034] The work safety management system of the present invention can detect the location information of workers and grasp the location, movement route, and work status prediction of workers even in indoor facilities where GPS radio waves cannot reach. By combining this location information with health index information, the health status of workers can be predicted or grasped.
[0035] At this time, during the private time of workers, such as before starting work or after finishing work in indoor facilities, by enabling the collection of worker location information and health index information to be stopped, consideration can be given to the privacy and personal space of workers.
[0036] In addition, based on the movement routes and work routines of workers, the safety of workers in terms of health and compliance with work safety procedures by workers can also be managed. Thereby, safety management can be carried out for individual workers and surrounding workers including those around the worker.
[0037] Also, when an abnormality occurs to a worker, in addition to the worker, people around the worker, i.e., bystanders, can also be notified of the occurrence of the abnormality. Thereby, early rescue of the worker with the abnormality can be made possible, or depending on the abnormal situation, bystanders can be prepared so as not to suffer secondary damage.

[0043] In the work safety management system according to the third invention of the present invention, in addition to the first or second invention, the working state detection unit detects the start and end of work of the worker in the indoor facility based on the communication with the portable terminal at the detection device provided at the entrance and exit of the indoor facility, Based on the start and end of the work, it is possible to detect whether the worker is in the working state or the non-working state.
[0044] With this configuration, based on entry and exit, it is possible to determine whether the worker is in the working state in the indoor facility.
[0045] In the work safety management system according to the fourth invention of the present invention, in addition to the third invention, the entrance and exit of the indoor facility further includes the detectable device capable of communicating for detecting the passage of the portable terminal.
[0046] With this configuration, it is possible to easily detect the working state by communication at entry and exit.
[0047] In the work safety management system according to the fifth invention of the present invention, in addition to any one of the first to fourth inventions, it further includes a signal receiving unit for receiving the combined result of the communication signal at the beacon terminal and the GPS signal, The signal receiving unit identifies the position of the worker based on the GPS signal based on the position of the worker inside the indoor facility obtained by the communication of the beacon signal with the portable terminal and the positioning position on the GPS of the beacon terminal. The position detection unit detects the position of the worker by receiving the information specifying the position of the worker from the signal reception unit.
[0048] With this configuration, even in an indoor facility, the position of the worker can be detected.
[0049] In the work safety management system according to the sixth invention of the present invention, in addition to any one of the first to fifth inventions, the portable terminal can transmit the health index information from the portable terminal by being carried by the worker.
[0050] With this configuration, health indexes such as vital data of the worker can be obtained.
[0051] In the work safety management system according to the seventh invention of the present invention, in addition to any one of the first to sixth inventions, the health index information includes at least one of the vital data of the worker, the temperature, humidity, discomfort index, and heat stroke index around the worker.
[0052] With this configuration, a wide range of indexes affecting the health state of the worker can be grasped. Based on this grasp, problems such as the health state can be judged early and surely.
[0053] In the work safety management system according to the eighth invention of the present invention, in addition to any one of the first to seventh inventions, a movement line detection unit that detects the work movement line of the worker based on the position detection result of the worker by the position detection unit is further provided. The movement line detection unit outputs the work movement line to the safety state determination unit.
[0054] With this configuration, normality and abnormality based on the work movement line of the worker can be grasped. Based on this grasp, problem behaviors and dangerous states of the worker can be judged.
[0055] In the work safety management system according to the ninth invention of the present invention, in addition to any one of the first to eighth inventions, the safety state determination unit determines at least one of a normal state, a health risk state, a work abnormality state, an accident occurrence state, and a missing state of the worker.
[0056] With this configuration, various states regarding the safety of the worker can be determined.
[0057] In the work safety management system according to the tenth invention of the present invention, in addition to the ninth invention, a notification unit is further provided that notifies the determination result of the safety state determination unit to the administrator and other workers (hereinafter, "surrounding workers") who are around the worker who is the subject of the safety state determination.
[0058] With this configuration, it is possible to prompt the surrounding workers to provide assistance, etc.
[0059] In the work safety management system according to the eleventh invention of the present invention, in addition to the ninth invention, the safety state determination unit determines the work abnormality state of the worker based on the work route, when the work route is significantly different from the original route, it is determined that there is a problem with the work state of the worker, and it is regarded as the work abnormality state.
[0060] With this configuration, early measures can be taken against work problems.
[0061] In the work safety management system according to the twelfth invention of the present invention, in addition to any one of the first to eleventh inventions, the safety state determination unit determines, based on the worker positions of a plurality of the workers, a state in which a certain number or more of the workers are concentrated as a concentrated state, and the notification unit notifies the workers in the concentrated state to keep a distance from each other.
[0062] With this configuration, problems caused by the concentrated state can be avoided.
[0063] In the work safety management system according to the 13th invention of the present invention, in addition to any of the 1st to 12th inventions, when the safety state determination unit cannot detect the worker position and the worker health information of a certain worker, it is determined that the mobile terminal possessed by the worker is inoperative, The notification unit notifies the surrounding workers of the worker to activate the worker's mobile terminal.
[0064] With this configuration, it is possible to avoid a state where the safety management of workers becomes impossible.
[0065] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0066] (Embodiment 1) (Work of Workers in Indoor Facilities) FIG. 1 is a schematic diagram showing an image of the working state of a worker in an indoor facility. The indoor facility 100 is various facilities that require work centered on indoor work, such as factories, distribution centers, distribution centers, construction sites, large shopping malls, and the like. Such facilities, the indoor facility 100 that requires work by workers inside, are in various places. The worker 200 enters the indoor facility 100 and performs various works inside the indoor facility 100.
[0067] If the indoor facility 100 is a factory, the worker performs work in the manufacturing process, transportation work on the production line, etc. Or, the worker may perform cleaning work. If the indoor facility 100 is a construction site, the cleaner 200 performs construction work, cleaning work, etc. If the indoor facility 100 is a distribution center, a distribution center, etc., the worker 200 performs work such as loading, shipping, inspection and transportation associated therewith.
[0068] In addition, the worker 200 starts working by entering (entering the building) the indoor facility 100 and ends the work by leaving the indoor facility 100. That is, the worker 200 is in a working state while inside the indoor facility 100, and is not working while outside the indoor facility 100. That is, by managing entry and exit, it is possible to determine whether the worker 200 is in a working state or a non-working state.
[0069] In FIG. 1, a state where the worker 200 is performing various operations inside the indoor facility 100 is shown. Also, a state of entering and leaving the indoor facility 100 is shown. In the case of a working state, there is also a state of normal work, which is also shown.
[0070] On the other hand, in the above-described indoor facility 100, various accidents also occur to the worker 200. In FIG. 1, a state where the worker 200 has fallen and a state where the worker 200 has been involved in an accident are shown. There may be normal work, accidents such as a falling state or an accident state, or work that is not an accident but has deviated from normal work.
[0071] In this way, in the indoor facility 100, the worker 200 may be working smoothly and normally, there may be work errors, or there may be a possibility of being involved in various accidents. In the indoor facility 100, it is difficult to grasp the situation from the outside, and at a construction site, etc., the internal structure of the indoor facility 100 changes day by day. In such a situation, it is difficult to detect the working state and accidents of the worker 200 at an early stage. Also, at the same time as early detection, if it is an accident state, it is also necessary to rescue the worker 200 at an early stage.
[0072] On the one hand, since it is an indoor facility 100, even if the worker 200 owns a mobile terminal, communication with the GPS signal is impossible. For this reason, the position of the worker 200 cannot be grasped. As a result, there is a problem that it is difficult to grasp various states of the worker 200. As described above, if various states of the worker 200 cannot be grasped, it will cause problems for the safety and health of the worker 200.
[0073] In view of such a situation and background, the present invention aims to manage the safety state of the worker 200 working inside the indoor facility 100 even when external GPS communication cannot be directly used. Also, in consideration of the privacy of the worker 200, it is also considered not to over-manage the worker 200 when not in a working state.
[0074] (Overall Summary)
[0075] FIG. 2 is a block diagram of the work safety management system according to Embodiment 1 of the present invention. FIG. 2 also shows the relationship between the work safety management system 1 and the indoor facility 100 it manages. The work safety management system 1 manages the safety state of the worker 200 in the indoor facility 100.
[0076] In FIG. 2, the work safety management system 1 is shown to be outside the indoor facility 100 and manage the safety state of the worker 200. The work safety management system 1 may be provided outside the indoor facility 100 in this way and managed from the outside. Alternatively, it may be provided inside the indoor facility 100 and managed from the inside. The physical location of the work safety management system 1 is not particularly limited. As long as the necessary work safety management can be performed, its physical location can be anywhere.
[0077] The work safety management system 1 may be realized by various devices and facilities capable of executing processing, such as a computer, a dedicated device, a mixture of these and software, a server device, etc. As described above, it may also be realized by a mixture of hardware and software. Further, it may be realized by being incorporated into general-purpose devices such as a computer or a server device.
[0078] The work safety management system 1 includes a work state detection unit 2, a position detection unit 3, a health information detection unit 4, and a safety state determination unit 5. Also, although related to the above, when the work safety management system 1 is incorporated into general-purpose devices such as a computer or a server device, these elements may be realized by hardware, software, etc.
[0079] Also, in FIG. 2, although it is shown that the physical positions of the indoor facility 100 and the work safety management system 1 are separated, some or all of the elements of the work safety management system 1 may also be provided inside the indoor facility 100. For example, at least a part of the elements constituting the work state detection unit 2 may be provided inside or at the periphery of the indoor facility 100.
[0080] The work state detection unit 2 detects that the worker 200 is in a work state of working in the indoor facility 100. That is, it can detect whether the worker 200 is working in the indoor facility 100 or is outside the indoor facility 100 and not in an indoor work state. When managing the safety state of the worker 200 by this work state detection unit 2, in the case where it is not in the work state inside the indoor facility 100, that is, in a private state, it can be set not to be in a managed state. That is, by not performing excessive management in the private state, respect for the personality of the worker 200 can be achieved.
[0081] The working state includes the situation where the worker 200 is inside the indoor facility 100 (for example, a construction site or a distribution center). When inside the indoor facility 100, since the worker 200 is considered to be in a state of serving the work, if the worker 200 enters the indoor facility 100, the working state detection unit 2 determines that the worker 200 is in the working state. Conversely, if the worker 200 exits the indoor facility 100, the working state detection unit 2 determines that the worker 200 is not in the working state.
[0082] Figure 4 is a block diagram showing the detection of the working state by the working state detection unit 2 in the first embodiment of the present invention. Near the entrance and exit of the indoor facility 100, a detection device 21 is provided. The detection device 21 has a communication function capable of communicating with the mobile terminal 300 held by the worker 200. The mobile terminal 300 is a smartphone, mobile phone, tablet terminal, etc. provided to the worker 200 for personal use or for work.
[0083] The detection device 21 is provided near the entrance and exit of the indoor facility 100 and can communicate when the mobile terminal 300 held by the worker 200 comes close. For example, communication can be performed by a function such as short-range communication such as Bluetooth (registered trademark). In this communication, if the detection device 21 detects that the mobile terminal 300 approaches the indoor facility 100, it means that the worker 200 is entering the indoor facility 100. If the detection device 21 detects that the mobile terminal 300 moves away from the indoor facility 100, it means that the worker 200 is exiting the indoor facility 100.
[0084] By the fact that the specific movement direction is entering or leaving the room rather than the approaching or leaving direction, the detection device 21 can also detect the entry and exit of the worker 200.
[0085] The detection device 21 can detect whether the worker 200 starts or ends work in the indoor facility 100 based on communication with the mobile terminal 300. The work status detection unit 2 can detect whether the worker 200 is in a working state or a non-working state based on the start and end of work detected by this detection unit 21. When it can be detected that the worker is in a working state, the work safety management system 1 performs position detection and safety management of the worker 200 in the indoor facility 100.
[0086] In this way, by making the detection of the work status of the worker 200 by the work status detection unit 2 a prerequisite for safety management, safety management considering the privacy of the worker 200 can be performed.
[0087] That is, the position detection unit 3 and the health information detection unit 4 operate only when the worker is in a working state. By such an operation, it is possible to ensure the privacy of the worker 200.
[0088] Also, as shown in FIG. 4, it is also preferable that the detection device 21 is provided at the entrance and exit of the indoor facility 100. By being provided at the entrance and exit, it is possible to detect whether the worker is in a working state based on the detection of entry and exit.
[0089] The position detection unit 3 receives the position information of the worker 200 in the indoor facility 100 based on the mobile terminal 300 held by the worker 200 and the communication device 400 installed in the indoor facility 100. Based on the reception of this position information, the position of the worker 200 in the indoor facility 100 is detected.
[0090] The worker 200 is inside the indoor facility 100. The worker 200 holds the mobile terminal 300, but in the indoor facility, the mobile terminal 300 may not be able to communicate directly with the GPS signal. Therefore, the position detection unit 3 detects the position of the worker 200 in the indoor facility 100 based on the communication device 400 installed in the indoor facility 100 and the mobile terminal 300. At this time, the position of the worker 200 in the indoor facility 100 may be detected by combining the beacon terminal and the GPS signal.
[0091] Here, with the configuration as shown in FIG. 3, it is also suitable for the position detection unit 2 to detect the position of the worker 200. FIG. 3 is an explanatory diagram for explaining position detection in the first embodiment of the present invention. The communication device 400 is installed at necessary locations in the indoor facility 100. For example, the communication device 400 may be installed at a position corresponding to a partition, a living room, etc., which can be an address for detecting the position of the worker 200.
[0092] As shown in FIG. 3, the communication device 400 includes a beacon terminal 410. The portable terminal 300 communicates with this beacon terminal 410. This is because the portable terminal 300 and the beacon terminal 410 can communicate even inside the indoor facility 100. They may communicate by signal communication such as the Bluetooth (registered trademark) standard. Since an address corresponding to the position in the indoor facility 100 is assigned to the beacon terminal 410, the position of the worker 200 inside the indoor facility who holds the portable terminal 300 can be known by receiving the beacon terminal 410.
[0093] The beacon terminal 410 can communicate with a GPS signal 420 (which can be considered as a GPS signal source. It is a device that can obtain the position as the GPS position. Or it may be a device or device that can be associated with the position on the map). This is because the beacon terminal 410 is network-connected to the device of the GPS signal 410. By connecting the beacon terminal 410 and the GPS signal 420, the position of the worker 200 who holds the portable terminal 300 that communicates with the beacon terminal 410 can be known.
[0094] Here, a signal receiving unit 32 is further provided to receive the combined result of the communication signal of such a beacon terminal 410 and the GPS signal 420. The signal receiving unit 32 receives the position of the worker 200 in the indoor facility 100 obtained by the communication of the beacon signal with the portable terminal 300. And the signal receiving unit 32 receives a GPS signal based on the positioning position (position in geographical positioning) of the beacon terminal 410 on the GPS.
[0095] The signal receiving unit 32 outputs this result to the position detecting unit 3. Based on this result, the position detecting unit 3 detects the position of the worker 200 within the indoor facility 100. That is, the position is detected based on the information specifying the position of the worker 200 from the signal receiving unit (information specified from the correlation between the beacon signal and the GPS signal).
[0096] In this way, even inside the indoor facility 100, the position detecting unit 3 can detect the position of the worker 200.
[0097] The mobile terminal 300 can collect the health index information of the worker 200 and output it to the beacon terminal 410. Alternatively, if possible, it can be output to the signal source device or network device related to the GPS signal 420. The health index information includes at least one of the vital data of the worker 200, the temperature, humidity, discomfort index, and heat stroke index around the worker 200. The vital data includes the body temperature, blood pressure, respiratory rate, heart rate, etc. of the worker 200.
[0098] Since the mobile terminal 300 is held by the worker 200, it can measure the health index information including vital data, etc. This measurement is performed continuously. That is, the continuously measured health index information is transmitted to the health information detecting unit 4 through the beacon terminal 410 or the like. The health information detecting unit 4 can detect the worker health information transmitted through such a communication path.
[0099] Since the mobile terminal 300 is held by the worker 200, the collected health index information can be transmitted from the mobile terminal 300.
[0100] FIG. 5 is a block diagram of the work safety management system according to Embodiment 1 of the present invention. It shows a state including the configurations of FIGS. 3 and 4. The health information detecting unit 4 can receive the health index information from the communication device 400 via the signal receiving unit 32 as shown in FIGS. 3 and 4. Alternatively, the health index information may be received through the communication path with the communication device 400. The receiving path may be selected according to the configuration of the network connection. By this reception, the worker health information can be detected.
[0101] The health information detection unit 4 outputs the received worker health information to the safety state determination unit 5 after performing necessary processing or in its original state. The position information detection unit 3 also outputs the detected position information of the worker to the safety state determination unit 5.
[0102] The safety state determination unit 5 determines the safety state of the worker 200 based on the worker position, which is the position of the worker 200, and the worker health information. As described above, these operate only when the worker 200 is in the working state.
[0103] The safety state determination unit 5 can determine whether the worker 200 is in a safe working state, whether any abnormalities have occurred, whether the worker is in a dangerous state, or whether an abnormality or danger is approaching. Also, when making the determination, the position of the worker 200 is included. As a result, it is possible to quickly grasp which worker 200 at which location has a safety problem. With this early grasp, the work safety management system 1 can quickly provide assistance to the worker 200 at a certain position.
[0104] (Determination of safety state) The safety state determination unit 5 determines at least one of the normal state, health - dangerous state, work - abnormal state, accident - occurrence state, and missing - information state of the worker 200.
[0105] (Normal state) Based on the worker position and worker health information of the worker 200, it can be determined that the worker 200 is in a normal state without problems. For example, when there is the following information, the safety state determination unit 5 can determine that it is in the normal state.
[0106] Vital data: within the normal range. Surrounding information: Temperature, humidity, etc. are within the normal range. The discomfort index, etc. is also within the normal range.
[0107] If such conditions are met, it can be determined as the normal state. In addition, Operator position information: It is in an appropriate position in view of the work content of Operator 200.
[0108] If there is no abnormality in the position where such an operator 200 is located, it is also preferable to determine that it is in a normal state in combination with the operator health information. By adding such elements, the normal state of the operator 200 can be judged more accurately. In particular, if the indoor facility 100 is a construction site, a distribution center, etc., by taking into account the overall health status, surrounding environment, working position, etc., it is accurately judged to be in a normal state.
[0109] If it is in a normal state, an administrator who manages the work safety management system 1 can grasp the safety of the operator 200. Based on this grasp, it can be considered that there is no problem with the continuation of the work by the operator 200.
[0110] (Healthy dangerous state) Based on the operator position and operator health information of the operator 200, it can be judged that there is a health problem occurring or a potentially healthy dangerous state for the operator 200. For example, when there is the following information, the safety state determination unit 5 can judge that it is in a healthy dangerous state.
[0111] Vital data: Any one index or a certain number of types of indexes are out of the normal range. For example, the body temperature is higher than the normal temperature, or the heart rate is rising, etc.
[0112] Surrounding information: The discomfort index exceeds the normal range, or the heat stroke index is high. Or the temperature and humidity are in a very high state, etc.
[0113] In such a state, there is a risk that the operator 200 may collapse due to heat stroke or overwork. Or there is also a possibility of being in that state. In such a case, actions to ensure the safety of the operator 200 are required of the administrator or other operators 200. For example, rescuing or first-aiding the operator 200. Of course, asking the operator 200 to take a rest, etc.
[0114] Furthermore, a health risk state may be determined taking into account the location information. Location information: When location information different from the original working position of the worker 200 is detected. In particular, when it is in a position significantly different from the work flow (including breaks, etc.), or is located in a dangerous area.
[0115] The administrator of the work safety management system 1, other workers 200, or persons related to this work safety management system 1 rescue the worker 200 in a health risk state. Thereby, health damage to the worker 200 can be minimized or prevented from occurring. In particular, there is an advantage in that actual health damage is not caused by being able to perform rescue at a stage when a dangerous state is likely to occur.
[0116] (Abnormal work state) Based on the worker position and worker health information of the worker 200, it can be determined that an abnormal work state has occurred or may occur to the worker 200. For example, in the following cases, the safety state determination unit 5 can determine that it is an abnormal state of the worker.
[0117] Location information: Judging from the work content and its characteristics of the worker 200, the worker 200 is not in the position where he / she should be. Or, the worker 200 has entered a dangerous area. Surrounding information: States such as abnormal high temperature or abnormal humidity (dry or humid).
[0118] In such a state, there is a possibility that the worker 200 is not performing the work that should be done in an appropriate place, or is mistakenly working in a dangerous area. For this reason, the worker 200 may be involved in danger or an accident. Or, there is also a possibility that the worker 200 is taking an unfavorable action.
[0119] The administrator of the work safety management system 1 is required not to neglect the risks and unfavorable conditions of such 200 workers. Therefore, the safety status determination unit 5 determines that the worker 200 is in an abnormal working state.
[0120] By notifying this determination result, the administrator and other workers 200 can take appropriate actions. Alternatively, by notifying the worker 200, the worker 200 can also be urged to improve the situation.
[0121] Also, by taking into account the case where an abnormal value is found in any of the health indicators included in the vital data, it is also advisable to determine an abnormal working state. For example, when the heart rate is high and the position where the worker 200 is located is unfavorable, there is a concern that some inappropriate behavior is being carried out. The safety status determination unit 5 determines the possibility of such inappropriate behavior as an abnormal working state.
[0122] Of course, in terms of preventing the worker 200 from being involved in danger, it is also preferable that an abnormal working state is determined.
[0123] Also, as shown in FIG. 6, it is also preferable to further provide a movement route detection unit 7 that detects the work movement route of the worker 200 based on the position detection result of the worker 200 by the position detection unit 3. FIG. 6 is a block diagram of the work safety management system in Embodiment 1 of the present invention. The movement route detection unit 7 is further provided.
[0124] The movement route detection unit 7 can detect the movement route, which is the movement path of a certain worker 200. By continuously connecting the worker positions, the work movement route can be detected. The movement route detection unit 7 outputs the movement route detection result of the worker 200 to the safety status determination unit 5. The safety status determination unit 5 can also determine the abnormal working state of the worker 200 when there is an abnormality in the work movement route.
[0125] If the work flow is significantly different from the original flow, the safety status determination unit 5 may determine that there is a problem with the working state of the worker 200 and that it is an abnormal working state. The fact that the work flow is significantly different means that the worker 200 may be performing incorrect work or undesirable work. Alternatively, there may be a problem with the health state, causing an abnormality in the work flow.
[0126] From this perspective, it is also preferable for the safety status determination unit 5 to determine an abnormal working state based on the abnormality of the work flow detected by the flow detection unit 7. If an abnormal working state is determined, it is possible to ensure the safety of the worker 200 and correct the work.
[0127] (Accident occurrence state) The safety status determination unit 5 can determine the accident occurrence state based on the position information of the worker 200 and the worker health information. For example, in the following cases, it can be determined as the accident occurrence state.
[0128] Vital data: Abnormal decrease in heart rate, etc. States such as decrease in blood pressure, etc. Position information: There is no change in the position of the worker 200 for a certain period of time or more.
[0129] In such cases, the worker 200 may have fallen or may be complaining of illness or the like. Alternatively, the worker 200 may be involved in an accident during work. Leaving these unattended is not preferable from the perspective of ensuring the safety of the worker.
[0130] Also, when the work flow in the flow detection unit 7 is an abnormal flow (staying in one place or moving to a place not related to work), there is also a possibility that the worker 200 is involved in an accident or injury. Also in this case, the safety status determination unit 5 can determine that it is an accident occurrence state, either in combination with other information or independently.
[0131] (Missing state) The safety status determination unit 5 can determine a missing status where the whereabouts of the worker 200 become unknown based on the position information of the worker 200, the health information of the worker, and the work route.
[0132] For example, when the work route is interrupted and the worker does not remain inside the indoor facility 100, it can be determined as a missing status. Or, when the position information disappears, it can be determined that the worker 200 is in a missing status.
[0133] The fact that the whereabouts are unknown means that the worker 200 may be involved in an accident or incident, or may be slacking off work. Leaving such a situation unattended is not preferable in terms of safety management or business management.
[0134] By determining the missing status, the safety status determination unit 5 can prompt appropriate responses by the administrator.
[0135] (Determination by combination of multiple elements) The safety status determination unit 5 determines the status of the worker 200 based on the position information, the health information of the worker, etc. as described above. As described above, it may be determined based on a certain element, or may be determined based on a combination of multiple elements. Or, it may be determined based on a single element. Also, when based on multiple elements, this combination may be processed in various ways. Also, if necessary, the reference elements may be changed.
[0136] By determining the safety status through such flexible processing, an appropriate determination of the safety status can be made.
[0137] Also, it may be determined for states other than the normal state, the health hazard state, the work abnormality state, the accident occurrence state, and the missing state described above. These can also be corrected and improved retrospectively.
[0138] (Notification unit) As shown in FIG. 7, it is also preferable to further include a notification unit 8 that notifies the determination result of the safety state determination unit 5. FIG. 7 is a block diagram of the work safety management system according to Embodiment 1 of the present invention.
[0139] The notification unit 8 notifies the result of the safety state determination unit 5. It notifies the administrator of the work safety management system 1. Or it notifies other workers 200. By this notification, the administrator and other workers 200 can know that there is a problem with a certain worker 200. Based on this recognition, corresponding work can be taken.
[0140] As described above, the work safety management system 1 in Embodiment 1 can accurately determine the safe state and dangerous state of the work state while considering the privacy of the worker 200. Also, even in an environment where the GPS signal cannot be directly received in the indoor facility 100, the combination of beacon communication and GPS signal can surely grasp the position of the worker 200. Based on this position information and health information, the state of the worker 200 can be determined more accurately.
[0141] Due to the accuracy and real-time nature of such determination, the safety of the worker can be appropriately managed. As a result, industrial accidents and the like can be prevented.
[0142] (Embodiment 2)
[0143] Next, Embodiment 2 will be described. In Embodiment 2, various ideas and variations will be described.
[0144] (Notification to surrounding workers by the notification unit) As shown in FIG. 7, the work safety management system 1 includes a notification unit 8. As described in Embodiment 1, the notification unit 8 notifies the determination result of the safety state determination unit 5 to the administrator or the like. This is because the safety management of the worker 200 can be performed by notifying the administrator. Also, if there is a dangerous state for the worker 200, it can lead to the rescue of the worker 200 and the like.
[0145] Here, in addition to the administrator, it is also preferable for the notification unit to notify other workers (hereinafter referred to as "peripheral workers") who are near the worker 200 targeted for safety status judgment. For example, in FIG. 1, there is a worker 200 in an accident state or a fallen state. The safety status judgment unit 5 determines that this worker 200 is in an accident occurrence state.
[0146] If it is in an accident state, it may be too late if the administrator recognizes it and then starts rescue activities. Also, there may be situations where the administrator cannot go to the rescue. The notification unit 8 notifies the peripheral workers. By this notification, the peripheral workers can immediately rescue or evacuate the worker 200 in an accident occurrence state or the like.
[0147] Based on the worker's health information and position information, the safety status judgment unit 5 can determine at least one of the fall, weakened consciousness, and sudden change in physical condition of the worker 200 as an accident occurrence state. If there is a sudden drop in blood pressure, a sudden drop (or sudden increase) in heart rate, etc., it can be determined that there is a fall or sudden change in physical condition. The safety status judgment unit 5 determines this as an accident occurrence state.
[0148] Upon receiving this judgment result, the notification unit 8 notifies the peripheral workers of the judgment result. The peripheral workers can rescue the worker 200 in an accident occurrence state. It is also preferable for the notification unit 8 to notify the peripheral workers of the accident occurrence state together with a rescue request. Upon receiving this, the peripheral workers will rescue or evacuate the worker 200 facing the accident.
[0149] By being notified to the peripheral workers, earlier rescue and the like become possible compared to the administrator. This is because the peripheral workers are closer to the worker 200 in an accident state than the administrator and can respond earlier. By such a response, the safety of the worker 200 can be ensured more reliably.
[0150] FIG. 8 is a schematic diagram showing notification to peripheral workers in Embodiment 2 of the present invention. As shown in FIG. 8, a certain worker is in a state where an accident has occurred. The notification of this accident-occurring state is given to the peripheral workers of the worker 200 in this accident-occurring state. Further, in the notification, it is also notified that it is occurring at a certain position around the peripheral workers and a rescue request.
[0151] In FIG. 8, a certain worker is in an accident-occurring state where he has fallen or had an accident. The safety state determination unit 5 that has determined this notifies the peripheral workers through the notification unit 8. Based on this notification, the peripheral workers rescue the worker in the accident-occurring situation.
[0152] (Determination of crowded state) In the indoor facility 100, the workers 200 may become crowded. If the workers 200 become crowded, there is a concern that it may hinder the work or cause an accident during the work. Also, when an infectious disease is prevalent, crowding is not preferable as a measure against infectious diseases. It is preferable from the viewpoint of work safety management that such a crowded state can also be determined.
[0153] The safety state determination unit 5 can obtain information from the traffic line detection unit 7 and the position detection unit 3. Based on the worker positions of a plurality of workers 200, a state where a certain number or more of workers 200 are crowded is determined as a crowded state. By detecting that a certain number or more of workers 200 are concentrated in a certain range, it can be determined that it is a crowded state.
[0154] That is, the crowded state can be determined by the worker density at a certain location. The criteria for the certain number and worker density for determining this crowded state may be determined as appropriate. It may be determined in various ways depending on the type of the indoor facility 100, the type of work of the workers 200, the external environment, empirical values, etc. Also, it may be changed according to the situation.
[0155] Further, based on the work trajectories of multiple workers 200 from the trajectory detection unit 7, the density state may be determined. If multiple work trajectories are concentrated, or if it is predicted that multiple work trajectories will concentrate in the same direction and at the same time period, it is determined as the density state.
[0156] When the safety state determination unit 5 determines this density state, it outputs it to the notification unit 8. The notification unit 8 notifies this density state to the worker 200. By passing through the communication device connected to the network, it is possible to notify the density state to the mobile terminal of the worker 200, etc. (Notification to surrounding workers is also possible through the same route).
[0157] In this notification, the worker 200 in the density state is also instructed to keep a distance. By this notification, the worker 200 can eliminate the density state.
[0158] (Judgment of inactivity) When the safety state determination unit 5 cannot detect the worker position and worker health information of a certain worker 200, it determines that the mobile terminal 300 held by the worker 200 is in an inactive state. Of course, there may be possibilities such as communication failures, but it is possible that the worker 200 has turned off the power of the mobile terminal 300, or the power of the mobile terminal 300 has run out.
[0159] Leaving this situation unattended is not preferable from the perspective of the safety management of the worker 200.
[0160] The notification unit 8 notifies the surrounding workers of the determination result of inactivity by the safety state determination unit 5. The surrounding workers are notified to activate the mobile terminal 300 for the worker 200 who is determined to have an inactive mobile terminal. By receiving this notification, the surrounding workers cause the worker 200 to activate it.
[0161] By this activation, the safety management of the worker 200 can be appropriately carried out.
[0162] Even in the case where it becomes difficult to perform safety management because the mobile terminal 200 of the worker 200 is not operating, the work safety management system 1 can handle it.
[0163] Note that the work safety management systems described in Embodiments 1 to 2 are examples for explaining the gist of the present invention, and include modifications and improvements without departing from the gist of the present invention.
