TECHNICAL FIELD OF THE INVENTION
The present invention relates to a safety confirmation method for confirming the safety of a worker who works alone, and promptly responding to an emergency such as a disaster, accident, or sudden illness.
[0002]
[Prior art]
In recent years, due to automation, versatility, and rationalization of personnel with the improvement of productivity, the number of work sites (workplaces) that perform single work tends to increase, and it is necessary to ensure safety for workers during such single work. It is performed as follows.
(1) Workers in other departments regularly visit and check the workplace where one person works.
{Circle around (2)} A worker in a single-working workplace carries a dedicated transmitter and presses a button on the transmitter in the event of an abnormality, thereby wirelessly issuing an alert such as a patrol light or a buzzer installed in a nearby workplace.
(3) While carrying a dedicated transmitter with a built-in tilt sensor, it activates an alarm when the operator's body is tilted (about 70 °) in addition to a button alarm.
[0003]
[Problems to be solved by the invention]
However, the above method (1) involves problems such as overlapping time periods during which each worker is unable to leave the workplace, biased patrols due to distant workplaces, and skipping patrols. I tended to be neglected.
Also, in the above method (2), since the emergency signal is a one-way communication, it cannot be confirmed even if a malfunction is caused by touching a button during a work, and when the user falls down due to unknown consciousness or the like. Contact was difficult. Further, there are disadvantages that the battery of the transmitter is hard to be noticed or that the transmitter does not operate when the transmitter is away from a predetermined area.
Further, in the above method (3), as in the case of the method (2), there is a drawback that even if the user touches the button and malfunctions, it cannot be confirmed, there is an erroneous detection of the falling sensor, and the cost is high. .

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments.
[0008]
FIG. 1 is an explanatory view for explaining an embodiment of a safety confirmation method according to the present invention, FIG. 2 is a block diagram, and FIG. 3 is a flowchart. The present invention will be described with reference to FIGS. 1 to 3. This safety confirmation method is performed, for example, by using a later-described safety confirmation system installed in a factory or the like.
[0009]
In this safety confirmation system, a telephone personal computer 1 having an automatic call function, a server 2, and an alarm monitoring personal computer 3 are connected by an in-house LAN 4, and the alarm monitoring personal computer 3 is installed in a security station 5 in the office. The telephone personal computer 1 includes a LAN board 6 and a sound source board 7. The LAN board 6 is connected to the in-house LAN 4, and the sound source board 7 is connected to an extension telephone 10 of the security station 5 via a PBX (private branch exchange) 8. Connected at In the present invention, the "telephone personal computer" refers to a personal computer provided with an automatic call function by software (program).
[0010]
Further, for example, mobile phones 11 (a, b, c, d) are distributed to workers in workplaces A, B, C, and D where one worker works in a factory. Note that it is also preferable to distribute the mobile phone 11 (e) to security personnel at a security station. Each of the mobile phones 11 is a general commercial product, and has a telephone number registered with a telephone company. With this configuration, two-way communication between the telephone personal computer 1 and each of the mobile phones 11 via the public line 12 becomes possible.
[0011]
The alarm monitoring personal computer 3 controls the telephone personal computer 1 to periodically call each of the mobile telephones 11... (A, b, c, d) of the worker based on the telephone schedule set and input in advance. . That is, for example, by default, the alarm monitoring personal computer 3 automatically schedules the monthly schedule from 19:00 to 7:00 on weekdays and all days on holidays by batch processing. , Schedule adjustments such as factory holidays are made, and the final telephone schedule for each month is set and input to the alarm monitoring personal computer 3. That is, the user sets and inputs which mobile phone is to be called at which time on which day.
[0012]
Next, a method for confirming safety by the safety confirmation system will be described. For example, in the case of confirming the safety of the worker in the workplace A, when the scheduled time is based on the telephone schedule, the telephone personal computer 1 automatically switches the mobile telephone 11 ( A call is made to a) using the public line 12. When the worker answers the telephone, the telephone personal computer 1 requests the worker to press the confirmation button by voice, and the worker presses the confirmation button on the mobile phone 11 (a) as instructed. The worker's safety is confirmed.
[0013]
In response to the instruction for requesting the confirmation button, for example, a voice saying “Please press sharp (♯)” is issued from the telephone personal computer 1, and when the operator presses the “ボ タ ン” button on the mobile phone 11 (a), Please press the zero sharp (0♯). " Then, when the worker presses “0♯”, a voice saying “Please work hard” is emitted, and the worker hangs up the telephone there. At this time, the tone generated when dialing out or pressing a button is determined by the sound source board 7 of the telephone personal computer 1. The sound source board 7 simply outputs the sound source by setting the frequency and time on the software, and converts the frequency and time of the input sound source to the software, so the input / output signals are performed on the software. .
[0014]
Further, when the telephone personal computer 1 makes a call to the mobile phone 11 (a), if the worker does not answer the phone after 10 calls (ringing tone), the phone calls again (second time) after a predetermined time, If you answer the phone, you will be instructed to request the confirmation button as described above. If you do not answer the second time, the telephone PC 1 will automatically call the extension phone 10 of the security station 5 and ask the security officer. By notifying that there is no response and transmitting an abnormality occurrence signal to the alarm monitoring personal computer 3 through the in-house LAN 4, an abnormality occurrence message is displayed on the screen of the personal computer 3.
[0015]
At this time, when the security staff comes out to the extension telephone 10, for example, an instruction voice saying “Please press a sharp (♯)” is issued from the telephone personal computer 1, and when the security staff presses the “♯” button of the telephone 10, "This is a one-person work safety confirmation system. There was no response from workplace A. Please investigate immediately. Please press 9 sharp (9♯)." Then, when the "9 ボ タ ン" button is pressed, a voice instruction saying "I have confirmed. Please investigate immediately" is issued, and the security officer hangs up. On the other hand, the personal computer 3 for alarm monitoring displays, for example, the characters "No response from workplace A. Please investigate immediately".
[0016]
Then, the security guard who is notified by telephone from the telephone personal computer 1 that there is no response from the workplace A calls the mobile phone 11 (a) of the worker at the workplace A via the public line 12. Check. If there is still no response, the security officer goes to the workplace A to check the safety of the worker, and promptly takes appropriate measures in an emergency such as an accident or sudden illness. In addition, before the telephone call from the telephone personal computer 1, if the worker can make a call by himself even if a trouble such as illness or injury has occurred, the extension telephone 10 of the security station or the mobile phone of the security guard The status report may be made by directly calling 11 (e).
[0017]
Also, when the telephone personal computer 1 calls the extension telephone 10 of the security station 5, if the security staff does not answer the call after 10 calls, the telephone call is made again (second time) after a predetermined time, and the telephone is still called. If not, the telephone personal computer 1 automatically contacts the holders (workers) of the mobile phones 11 (b), 11 (c), and 11 (d) by sequentially turning the telephone. Eventually, for example, it is also possible to make a call to a cell phone or home, such as a personnel manager or a factory manager.
[0018]
By the way, as described above, if there is no response from the worker in the workplace A called from the telephone personal computer 1, the time and contents at this time {for example, the workplace name, worker name, work contents, etc.} The log is recorded on the server 2 via the in-house LAN 4.
[0019]
Similarly to the safety check of the workers in the workplace A, the workers in the workplaces B, C, and D are also called from the telephone personal computer 1 at predetermined time intervals (for example, every 30 minutes). Confirm the safety to. Here, every predetermined time is a time interval for calling the same worker. That is, for example, it is not the time interval between the call to the workplace A and the call to the workplace B.
[0020]
Thus, in the present embodiment, the description has been made on the assumption that there are a plurality of single-working workplaces on the same site of the factory. However, a single-working workplace is located in another factory far (for example, 10 km) away from this factory. Even if the operator has a mobile phone, the safety can be checked by the safety check system.
[0021]
Also, this safety confirmation method (safety confirmation system) can be easily used on a world level. In other words, the in-house LAN 4 connecting the telephone personal computer 1, the alarm monitoring personal computer 3, and the server 2 is always connected to the Internet via the public line 12, so that the mobile phone in a single workplace such as a factory overseas can be used. Safety confirmation can be easily performed for the holder (operator).
[0022]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0023]
(According to claim 1) Since it is possible to confirm the safety of a worker who works alone using a generally available mobile phone 11 and a personal computer (telephone personal computer 1), the capital investment is very low. Yes, and highly scalable (can easily accommodate a large number of single workplaces). Further, since the mobile phone 11 and the telephone personal computer 1 can perform two-way communication, there is no abnormal alarm due to malfunction or false detection (like a conventional transmitter), and the reliability of safety confirmation is greatly improved.
[0024]
Further, in addition to the telephone call from the telephone personal computer 1 to the telephone 10 at the security station, a double notification can be performed by the message from the telephone personal computer 1 to the alarm monitoring personal computer 3 to notify the occurrence of the abnormality. In addition, since a log at the time of occurrence of an abnormality can be recorded in the server 2, appropriate and smooth post-processing (eg, application of workers' compensation insurance) can be performed, and disasters and accidents due to the work contents and work environment can be performed. It can be used to analyze the tendency of occurrence and to improve the situation.
[0025]
(According to claim 2 ) Since it is possible to easily and inexpensively confirm the safety of one worker at a world level, it is suitable for a company having a factory overseas.
