Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vibration base n amount management system, and in particular, is capable of efficiently managing the amount of vibration exposure for each worker engaged in vibration work.

[Summary of the invention]

The present invention uses an individual data collection card to collect vibration exposure amount Φ from workers at work sites where there is no data management equipment such as power supply equipment, communication equipment, transportation, diagnostic facilities, etc., in a vibration base quantity management system. By using an applicable individual vibration exposure meter, it is possible to easily create a database for managing the amount of vibration exposure.

[Conventional technology]

Conventionally, workers (simply referred to as "workers") who are engaged in work that involves holding vibrating tools such as chainsaws for felling, delimbing, and track maintenance tie-up tools, have to be exposed to vibrations at an appropriate level. Since there is a risk of vibration disorders in the hand-arm system, it is necessary to accurately detect the amount of vibration during vibration work. vibrates by causing anf
Methods of collecting detection information about 1 are being considered.

[Problem that the invention seeks to solve]

Incidentally, the work sites where workers are engaged are actually locations where experts such as doctors are located (in most cases, a management center located at the company's headquarters) who predict the occurrence of vibration disturbances and manage countermeasures. ) and are scattered in remote areas, making it difficult for a management center to manage them effectively.

Incidentally, the detection information obtained from each worker is collected in order to create statistical exposure vibration amount information along with work record information as information on preventive measures for hand-arm vibration disorders, and thus the detection information for each worker By accumulating information, it can be applied, for example, to setting vibration generation limits for tool vibrations, checking workers, and setting criteria for judgment at work sites.

In order to obtain detection information suitable for such purposes, it is desirable to obtain detection information under predetermined detection conditions at all work sites and to centralize this information in a management center without delay.

The present invention has been made in consideration of the above points, and aims to propose a vibration exposure amount management system that can accurately manage a large amount of vibration exposure amount information.

[Means for solving problems]

In order to solve this water problem, in the first invention, each worker who engages in vibration work at a work site wears an individual vibration exposure amount data representing the amount of vibration n to which the worker is exposed. The individual vibration exposure meter 11 writes on the individual data collection card 14 inserted in a detachable manner, and the individual vibration exposure meter 11 writes on the individual data collection card 14 installed at the field office and collects data from each worker. A vibration exposure data collection device that reads vibration exposure data, aggregates worker-specific management data for each worker, and creates a worker-specific database for the field office! 5.

Further, in the second invention, in addition to the configuration of the first invention, a vibration exposure method is provided in which a main database is created by accumulating vibration exposure amount management data created from workplace-specific databases of a plurality of field offices. A quantity data accumulation device W14 is provided.

[Effect]

When a worker wearing the individual vibration exposure meter 11 into which the individual data collection card 14 is inserted engages in vibration work at a work site, the amount of vibration exposure for the worker is detected and calculated each time the worker performs the work. The data is written to a separate data collection card 14.

The vibration exposure amount manager at the field office collects individual data collection cards from each worker who returns to the field office from the work site and manages the card classification, thereby checking equipment such as power supply equipment, communication equipment, transportation facilities, etc. By managing individual data collection cards carried by workers, it is possible to collect work data at work sites without data being lost. can be easily created and used in the main database creation process in the vibration exposure amount data collection device 4.

In this way, it is possible to easily construct a vibration exposure amount management system that can accurately manage the amount of vibration exposure based on the amount of vibration exposure exposed at the work site as a whole.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

(1) Overall structure of the management system In FIG. 1, l indicates the vibration exposure amount management system as a whole, and for example, the vibration exposure amount data collection device 4 consisting of the host computer 2 and database storage device 3 installed at the head office. multiple vibration exposure data collection devices 5
(5A, 5B...) are provided.

Each vibration exposure amount data collection device 5 (5A, 5B...
・) are located at the site office that serves as the base of the work site where vibration work is carried out, and each collects data read by the card reader 6 into the personal computer 7, and stores the collected vibration vibration amount data in a predetermined manner. The information is transmitted to the host computer 2 of the vibration exposure amount data collection device 4 via a data communication line at a timing of, for example, one day, one week, or one month, so that the information is accumulated in the database storage device 3.

Vibration SN amount data collection device N5 (5A, 5B...
・) At each field office where a vibration exposure meter 11 (IIA, IIB...) has been installed, individual vibration exposure meters 11 (IIA, IIB...) are distributed to the workers working at the work site in charge. is the personal vibration exposure meter 11 (11A,
By wearing IIB (...) and performing vibration work at a work site, it is possible to collect data on the amount of vibration exposure during work.

In other words, individual vibration exposure meters 11 (IIA, 11B...
...) inputs the vibration detection signal Sl obtained from the vibration detection sensor 12, which is an acceleration detector, into the vibration detection device main body 13, forms vibration exposure amount data, and transmits this vibration exposure amount data to the vibration detection device main body 13. Data can be written to an individual data collection card (consisting of a so-called IC card) 14 dedicated to each worker inserted into the computer.

The vibration exposure amount data written in the individual data collection card 14 in this way is obtained by inserting the individual data collection card 14 taken out from the vibration detection device main body 13 into the card reader 6 of the vibration exposure amount data compilation device 5. The information is read and collected by the personal computer 7.

In this embodiment, the vibration detection device main body 13 is stored in the pocket of the worker's work clothes, and the vibration detection sensor 12 is attached to the back of the worker's hand, so that the worker can use the individual vibration exposure meter 11. It is designed so that it can be carried around while holding a hand-held vibrating tool, such as a chainsaw, to perform felling work or chopping work.

As shown in FIG. 2, the vibration detection device main body 13 receives a vibration detection signal Sl supplied from the vibration detection sensor 12 through an input terminal TIN to a detection signal input circuit 14, and receives a detection input signal S2 obtained at its output terminal. The analog/digital conversion circuit 15 converts it into detection data S3 and sends it to bus 1.
6 to the central processing unit (CPU) 17.

The CPU 17 uses the detected data S3 taken in while using the work memory 19 having a random access memory (RAM) configuration according to the program data in the program memory 18 which is a read only memory (ROM) to calculate the following equation: Lvb□, T -10log, . W (dB)...
...By executing the calculation (1,), the equivalent tool vibration level L□, 1. Calculate T.

In equation (1), Lm is the first sampling point (
The sample value of the detection input signal S2 sampled by the analog/digital conversion circuit 15 at i=1, 2.3... The vibration energy is expressed as a ratio in (dB) to the reference vibration level.

Also, the expression in equation (1) is the vibration level L! After converting (aa) from a numerical value in (dB) to a rational number, it shows the accumulated value from i=1st to 1=nth, and the exponent of the cumulative value is i-1, 2... ...Nth vibration level (dB
) represents the total value of

Here, equation (1) means that the equivalent tool vibration level defined as an analog value by the following equation L vha□ T ...... (4) is collected as discrete sample data. .

In equation (4), a (t) is the instantaneous value C+++/Sec of the effective value of vibration acceleration weighted by the frequency response.
”) % am is the standard vibration acceleration 10-' (m/se
e”), and a (t)/aa is the instantaneous value a(
1) is normalized by the ratio with the reference vibration acceleration a, t and t represent the start and end times of measurement, respectively, and T=tt1 represents the actual measurement time.

Thus, equation (4), and therefore equation (1), is expressed as the actual measurement time T=t
! -tt indicates that the ratio of the vibration acceleration given to the vibration detection sensor 12 to the reference vibration acceleration is cumulatively calculated, and the cumulative calculation results are averaged over the actual measurement time T = tt - t. However, the power average value that can be obtained in this way means that the worker was exposed to an approximately equal amount of vibration represented by the power average value during the actual measurement time, and this means that the worker's vibration exposure The degree of this can be expressed quantitatively.

In this embodiment, the analog/digital conversion circuit 15
captures the detection data S3 representing the i-th vibration level tom (dB) into the work memory 19 via the bus 6 at a sampling time interval of 10 (sexec), and
PU17 is equivalent tool vibration level L I based on formula (1)
Tb@11+T is used as detection data to perform calculations according to the vibration exposure data processing program shown in FIG. 3, and the calculation results are stored in the work memory 19 as vibration exposure amount collection data.

The vibration exposure amount collection data accumulated in the work memory 19 in this way is transferred to the CPU 17 when the individual data collection card 14 is inserted into the card writer 21 at the end of the work.
The data in the work memory 19 is transferred to the card writer 21 so as to be written to the individual data collection card 14.

[2] Vibration exposure data collection process In FIG. 3, when the CPU 17 enters the vibration exposure data processing program from step SPI, it executes step SP
At step SP2, the vibration detection device main body 13 is initialized as a whole, and at this time, the data stored in the work memory 19 is cleared.At step SP3, the CPU 17 starts the conversion operation for one sample of the analog/digital conversion circuit 15, and then In step SP4, the operator is informed that the initialization of the processing program has been completed by flashing all "8" three times in all digits of the display 22.

Subsequently, the CPU 17 proceeds to step SP5 and determines whether the mode changeover switch 23A on the operation panel 23 (FIG. 2) is switched to the "measuring" mode.

In the case of this embodiment, the mode changeover switch 23A allows the operator to switch the vibration detection device main body 13 between the "measuring" mode and the "stop at -" mode, and the CPU 17 When the mode selector switch 23A is switched to the "- time stop" mode side, when a negative result is obtained in step SP5, the process moves to step SP6 and the conversion operation for one sample of the analog/digital conversion circuit 15 is completed. will be in a state of waiting.

In the standby state of step SP6, in consideration of the fact that the conversion processing speed of the analog/digital conversion circuit 15 is slower than the arithmetic processing speed of the CPU 17, the operation of the CPU 17 is controlled by the conversion operation of the analog/digital conversion circuit 15. This means that the CPU 17 is in an operation mode that synchronizes the operation of the CPU 17 with the timing at which the detection data S3 is sent to the bus 16.

Eventually, when a positive result is obtained in step SP6,
The CPU 17 moves to step SP7 and displays the detection data S3 obtained from the analog/digital conversion circuit 15 on the display 22 (FIG. 2) for a predetermined period of time (for example, 1 (
(see)) to notify the operator of the numerical value of the detection data S3 that is currently about to be captured, and then the process returns to step SP5 described above.

In this way, the CPU 17 repeatedly executes the processing loop of steps 5P5-3P6-3P7-3P5, unless the mode changeover switch 23A of the operation panel 23 is switched to the "measuring" mode.
3 on standby.

In this standby state, when the operator eventually switches the mode selector switch 23A to the "measuring" mode, the C
When a positive result is obtained in step SP5, the PU 17 moves to step SP8 and sets the data processing flag R.
It is determined whether UN is logic "1" or not.

If a positive result is obtained here, this means that the vibration detection device main body 13 as a whole is in data processing operation, and at this time, the CPU 17 executes the analog/digital conversion circuit 15 for one sample in step SP9. After confirming that the conversion operation has been completed, the detection data S3 is read into the work memory 19 in step 5PIO, the conversion operation for one sample of the analog/digital conversion circuit 15 is started in step 5PII, and the work is completed in step 5P12. The measurement time counter in the memory 19 is incremented.

Thus, the CPU 17 is the analog/digital conversion circuit 1.
The preparation for the arithmetic processing operation is completed for the one sample of detection data S3 taken in from step 5, and the subsequent step 5P
13 - Step 5 Regarding P1B, arithmetic processing operation of the detection data S3 is started.

That is, the CPU 17 first in step 5P13,
Equivalent tool vibration level L Wb described above for equation (1)
@Qr The T data is calculated as data representing the vibration level corresponding to the i-th sampling data, and the 8-hour normalized equivalent is calculated in step 5P14 using the data of the equivalent tool vibration levels L□, □T at the current sampling point. The data of the tool vibration level L,...8 is calculated, and in the following step 5P15, it is confirmed that the 8-hour standardized equivalent tool vibration level Lv□8 is less than the predetermined alarm value, and in step 5P16, the previous After calculating the number of calculation data n, select the data of the maximum tool vibration level L, □ in step 5P17, and proceed to step 5P.
1B, a time distribution map L for each tool vibration level is created.

When such arithmetic processing is completed, the individual vibration exposure meter 11 finishes collecting the vibration exposure amount data at one sampling point and stores it in the work memory 19, and in this state, the CPU 17 executes step 5P19.
The collected vibration exposure amount data is transferred to the card writer 21 and written in the individual data collection card 14.

Subsequently, in the next step 5P20, the CPU 17 calculates the measurement time l based on the count contents of the measurement time counter.
(sec) When it is determined whether or not the elapsed time has elapsed, and a positive result is obtained, the process moves to step SP21, and the calculation result is displayed on the display 22, and then the process moves to step 5P22, whereas in step 5P20, a negative result is obtained. , directly execute step 5 without processing step SP21.
Move on to P22.

In step 5P22, the CPU 7 determines whether the mode selector switch 23A is in the "stop at -" mode, and when a negative result is obtained (this means that the mode selector switch 23A is switched to the "measuring" mode position). ).

The CPU 17 moves to step 5P23 and waits for the next sampling point.

On the other hand, if a negative result is obtained in the above-mentioned step SP8, the CPU 17
Jump to P19 and go to step 5 P20.

When sampling time 10 (ssec) has elapsed, an affirmative result is obtained in step 5P23, and the CPU 17 moves to step 5P24 to determine whether one unit work time (for example, 10 hours) has elapsed. When a positive result is obtained, the data that has been taken into the work memory 19 so far is held in the waiting routine 25, and then the power is confirmed to have been turned off in step 5P26, and the vibration exposure is performed in step 5P27. Terminate the data collection processing program.

On the other hand, when the CPU 17 obtains a negative result in step 5P24, this means that one unit work time has not yet ended, so the process returns to step SP5 and continues. Repeat the process of collecting new vibration exposure data for the work.

Further, if the power has not been turned off in step 5P26 after waiting for a predetermined time in step 5P25, the CPU 17 assumes that the worker continues to work, and returns to the above-mentioned step SP5 to perform new detection regarding the next work. Repeat the vibration exposure data collection processing program for data S3.

The above is a processing procedure in a normal working state where a negative result was obtained in step 5P15 mentioned above.
If a positive result is obtained in step 15, this means that the vibration of the vibrating tool used by the operator has become abnormally large. At this time, the CPU 17 performs step 5P2B.
The operator is then notified of the occurrence of an abnormality by activating the alarm device 24 (FIG. 2) to emit an alarm sound.

At this time, the worker stops the work as shown in step 5P29, switches and operates the mode changeover switch 23A of the operation panel 23 to the r-time stop J mode, and then, as shown in step 5P30, Notify the on-site work manager of the occurrence of an abnormality.

In this state, the CPU 7 performs step 5P described above.
22, the mode selector switch 23A is set to "stop at -"
When it is confirmed that the mode has been changed, the process returns to the loop of steps 5P5-3P6-3P7-3P5 described above and waits for the changeover switch 23A to return to the "measuring" mode.

In this way, the individual vibration exposure meter 11 alerts the worker when vibration with an abnormally large amount of vibration exposure occurs, thereby preventing the worker from suffering damage to the hand-arm system if the worker continues to work. It is possible to prevent this from happening.

In the case of this example, the 8-hour normalized equivalent tool vibration level L calculated in step 5P14 in FIG. The standard exposure condition is used to evaluate that the operator continues to be exposed to vibrations of the amount represented by the 8-hour normalized equivalent tool vibration level L1.8 during a standard working time of 8 hours.

Further, the maximum tool vibration level L Vl11□ selected in step 5P17 represents the maximum vibration level to which the operator was exposed during the working time, and is used to evaluate how severe vibration the operator was exposed to.

Furthermore, the time distribution map L by tool vibration level created in step 5P1B calculates the total exposure time that occurs in a predetermined vibration level range (for example, a range of 12 vibration levels divided at 5 (dB) intervals). , is used to evaluate how strong the vibration was and how long the exposure was continued from the longest exposure time to the shortest exposure time.

Furthermore, the number n of data calculated in step 5P16
is used in the power averaging calculation when calculating the equivalent tool vibration level L VhmQ*T based on equation (1) in step 5P13.

[3] Management of vibration exposure amount data The vibration exposure amount management system l described above with reference to FIG. 1 is utilized in accordance with the management procedure shown in FIG. 4.

In other words, when the management procedure is started in routine RTO, a work plan at the head office is drawn up in routine RTI, and based on the work plan, routine RT2 is started.
Personal data was collected at the work site,
In routine RT3, work at the field office is managed based on the collected personal data.

The data created as a result of the work management at the field office is collected at the head office in routine RT4, and after overall work management is performed, the management procedure is ended in routine RT5.

The work planning routine RTI, as shown in FIG.
First, in Steps 5P41-3P43, the work planner at the head office analyzes the work contents and decides the schedule, and then prepares the equipment and measuring instruments, and then in Steps 5P44-5P4.
In Step 6, a worker is secured and the work content and personal data are examined while referring to the personal data file, and the suitability of the worker is confirmed in Step 5P46.

The study results are communicated from the head office to each work site in step 5P48, and the work sites MA, MB...MN carry out steps 5P49A-3P52A, 5P, respectively.
49B-3P52B...5P49N~5P52
At step N, the work plan created at the head office is examined, and if it is determined to be appropriate, the work plan planning routine is ended at step 5P53.

On the other hand, if it is concluded that the work plan prepared at the head office is not suitable, the head office is notified of the examination results and the work plan planning routine is ended in step 5P52.

Incidentally, if it is determined that the work plan is inappropriate in this way, by returning to the above-mentioned step SP41 and executing the work planning routine again, the work sites MA, MB,
...Steps 5P51A and 5P51 in MN
B...The work plan formulation procedure is repeated until SP51N obtains a review result that is appropriate.

In this way, when the planning of the work plan is completed in the routine RTI of the management procedure RTO (FIG. 4), the management procedure proceeds to the personal data collection routine RT2 at the work site.

The personal data collection routine RT2 is as shown in FIG.
Step 5P61 under the control of the work manager in the field office
- After preparing for on-site work in 3P65, individual vibration exposure meters are distributed to each worker, and individual data collection cards 14 are placed in the individual vibration exposure meters 11 (IIA, IIB...) that were distributed. After inserting and setting the personal vibration exposure meter 11 into the vibration detection device main body 13, a worker wearing the individual vibration exposure meter 11 moves to the site and prepares for measurement at the site.

In practice, for example, in the case of logging work, etc., the work site is in a mountainous area where it is difficult to prepare not only measuring equipment but also a power source to drive the measuring machine, so workers move to the site on foot as necessary. When the operator arrives at the factory, the operator attaches the vibration detection sensor 12 to the back of the worker's hand using, for example, special gloves, and the vibration detection device main body 13 is attached to the pocket of work clothes, and then the mode selector switch 23A of the operation panel 23 is set to "Measurement". Preparation for measurement is completed by switching to the mode.

In this state, the worker starts field work, for example, felling work while holding a chenzo, in step 5P66, and at this time, the vibration detection sensor 12 detects the vibration to which the worker's hands and arms are exposed, and the vibration is detected in the vibration detection device main body 13. By sending the vibration exposure data, the CPU 17 executes the vibration exposure data processing program described above with reference to FIG. .

In this way, while the individual vibration exposure meter 11 is collecting vibration exposure data in step 5P67, if the amount of vibration to which the worker is exposed becomes abnormally large, this is detected by the CPU 17 of the vibration detection device main body 13. Figure 2) is step 5P15 of the vibration exposure processing data processing program (Figure 3).
The operator can be notified by detecting this and activating the alarm 24 (Fig. 2), and at this time, the operator switches the mode changeover switch 23A (Fig. 2) to the "stop at -" mode to manage the work. Third, take measures such as contacting the person concerned.
Steps 5P28 to 5P30 in the figure), as a result, it is possible to avoid burdening the vibration worker with an excessive amount of vibration exposure.

Thus, when a worker finishes a day or multiple days of work,
The individual vibration meter 11 finishes collecting data to the individual data collection card 14.

When the work at the work site is thus completed, in steps SP68 to SP5P70, the worker takes out the individual data collection card 14 from the individual vibration exposure meter 11 and manages it personally, and also removes the individual data collection card 14 from the individual vibration exposure meter 11 and tools. is returned and the individual vibration exposure meter 11 is placed under the control of the site manager at the site office.

Then step SP71, SP? In step 2, the site manager collects individual data cards 14 from each worker on the predetermined measurement result collection day, and then proceeds to step 5P7.
Step 3 ends the individual data collection work procedure at the work site.

When the individual collection work at the work site is completed in this manner, data management work at the field office is performed in the data management routine RT3 (FIG. 4).

That is, as shown in FIG. 7, the individual data cards 14 collected from each worker are processed in steps 5P81 and 5P8.
In step 5P83, the data is managed in the individual data card management box, and nothing is done until a predetermined aggregation date is reached, and the data management work procedure at the field office is ended in step 5P83.

On the other hand, on the day of aggregation, the data manager at the field office uses the card reader 6 to read out the data on the individual data card managed in the individual data card management box in steps 5P84 to 5P8B, and 7, and at this time, the work memory 19 (second
If the work memory 19 is not full, the work memory 19 is cleared, and then the read personal data is written in the work file of the personal computer 7.

At this time, the personal computer 7 performs step 5P88.
In ~5P89, after compiling the work-specific management records, calculation processing for creating a work-specific database is executed, and daily reports, weekly reports, monthly reports, and annual reports are created based on the calculation results.

Thereafter, in steps SP94 to SP5P100, the data manager selects a data transmission method using a data communication line or a mailing method using a floppy disk as necessary to send the data to the head office, and then sends the data to the head office. , weekly report,
We examine the work plan based on monthly and annual reports, and if a problem is identified that requires changes to the work plan, such as when some workers are exposed to an abnormally high amount of vibration, we will notify the work manager of the changes. After contacting each worker through the work manager, the data management work procedure at the field office ends in step 5P83.

When the data management work at the field office is completed in this way, the management procedure moves to management routine RT4 (FIG. 4), and the data accumulation and comprehensive data management work procedure at the head office begins.

In this management routine RT4, the data manager at the head office performs steps 5PI11-3P114 as shown in FIG.
daily and weekly reports sent from each field office,
After importing the monthly report and annual report data into the host computer 2 from the communication line or floppy disk, a database is created and stored in the database storage device 3, and step 5P11
In Step 5, by performing multifaceted data processing based on the database, materials for examining the actual situation of the work site and its problems from the perspective of vibration exposure are created, and based on the materials, steps 5P116 to 5P127 are carried out. To enable comprehensive management.

In other words, the data manager performs steps 5P116 to 5P12.
7, based on the database, medical records (for example, No. 9
In addition to creating a personal vibration exposure data management file (as shown in Figures 1-12), if your health level is not good after receiving a diagnosis from a doctor based on this medical record, The results of the diagnosis will be communicated to each workplace to conduct a health check on the workers, and if there is a problem, the work content etc. at the work office will be changed.
We predict the amount of vibration exposure in conventional vibration work and take countermeasures and preventive measures against the problems, develop tools and protective gear, develop new construction methods for vibration work, and consider medical preventive methods. The data collection and comprehensive data management work procedure ends in step 5P128.

In this way, a series of management procedures (Fig. 4) can be created as a management routine RT.
It ends at 5.

[4] Effects of the embodiment According to the above configuration, each worker can use the individual vibration exposure meter 11.
By wearing the vibration exposure amount data for each worker at the work site, it is possible to easily and efficiently create a database with high detection accuracy for each work site. Incidentally, the collected vibration exposure data can be easily retrieved by simply removing the individual data collection card 14 from the individual vibration exposure meter 11, even if the location is far from the field office and there is no power supply equipment, communication equipment, etc. Data can be easily and reliably collected even at work sites such as

In this way, by using a management method that roughly classifies the cards, the vibration exposure amount data of the individual data collection card 14 can be collected by worker.
The data can be managed until it is collected in step 5, and even if there is a worker who is inexperienced in data processing, the data can be collected smoothly.

In addition, when data collected at multiple field offices is collected in the vibration exposure amount data collection device 4, a data administrator who is accustomed to data processing is required to collect data from multiple field offices based on a database created via a card reader at each field office. can be easily accumulated using a data processing device, and as a result, it is possible to construct a vibration exposure amount management system that is efficient as a whole and can manage accurate vibration exposure amount data.
