DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a worker management method for managing the amount of exposure of a worker, such as dust and radiation, which is exposed at a work site for each worker.

[0002]

2. Description of the Related Art In recent years, for example, pneumoconiosis lawsuits have been filed for workers at civil engineering construction sites and the like (particularly in tunnels), and the need to control the amount of dust exposure for each worker has increased. Conventionally, at a work site such as in a tunnel, a simple digital dust meter (such as a light scattering type) is installed to grasp the dust concentration at the work site.

[0003]

However, although there is a method for determining the dust concentration at the work site,
There was no useful method to accurately control the amount of dust exposure for each worker. In addition, workers who move from one work site to another can not control the amount of dust that has been accumulated and exposed. I couldn't manage it every time.

Accordingly, an object of the present invention is to provide a method for managing workers, which makes it possible to appropriately manage the amount of exposure for each worker.

[0005]

Means for Solving the Problems To solve the above problems, the invention according to claim 1 is, for example, a method for managing workers, as shown in FIG. At least one of the entry and exit is controlled by the IC card held by the worker, and the integrated exposure of the worker exposed at the work site from entry to exit of the work site is calculated. In addition, the data is managed for each worker.

Here, the work site may be, for example, a civil engineering work site such as a tunnel. In this case, the exposed material is dust or the like. Or,
In other cases, for example, the work site may be a place where radiation is present (such as a nuclear power plant), and what is exposed may be radiation. Alternatively, the work site may be a place where a toxic gas is present, and what is exposed may be a toxic gas.

Further, as an IC card, a contact type I card is used.

A signal is transmitted to the data management device, and the data management device recognizes that the worker has entered and the entry time. Similarly, at the time of exit, the card reader (card reader / writer) reads the IC card, so that the data management apparatus recognizes that the operator has exited and the exit time. Thereby, the entry time is obtained from the difference between the entry time and the exit time. In addition, the concentration of the substance to be exposed, that is, the exposure concentration, is measured by the concentration measuring means, and the data management device integrates using the entrance time and the exposure concentration (for example, by multiplying the entrance time and the exposure concentration). Calculate the exposure. Then, the calculated integrated exposure data is stored in an IC
It is sent to a card reader / writer and recorded on an IC card.

Alternatively, when data is not recorded on the IC card (when data is managed only by the data management device), the IC card may not be read at the time of entry and exit.

Embodiments of the present invention will be described below with reference to the drawings. A worker management system 1 for implementing the worker management method according to the present invention.
For example, as shown in FIG. 1, an IC card reader / writer 2 for reading and recording on an IC card 1 held by an operator, an integrated exposure amount, an accumulated exposure amount, and a cumulative exposure amount for each work site. A data management device 3 for calculating and managing health data such as quantity, a concentration measuring means 4 for measuring the concentration of dust, a concentration managing means 8 for collectively managing the dust concentration in each area in the work site, and the like. ing.

The concentration measuring means 4 is, for example, a dust meter of a light scattering type or the like, and is installed for each work area in a tunnel (work site). The measurement of the dust concentration by the concentration measuring means 4 is performed at any time, and the data of the dust concentration measured by the concentration measuring means 4 is sent to the PHS communication device 6 via the data logger 5,
The data is transmitted from the S communication device 6 to the PHS communication device 7 of the data management device 3 wirelessly. Where PH
The S communication devices 6 and 7 constitute a wireless communication unit. Then, the data of the dust concentration in each work area is managed (understood) in real time by the concentration management means 8.

In addition, when the value measured by the concentration measuring unit 4 reaches a predetermined value or more, a warning unit (for example, “wearing a dustproof mask”) that issues a warning or the like to the work area or the like (not shown). ), The worker can recognize the warning and recognize that the dust concentration has reached a predetermined value or more, and can respond accordingly.

The IC card reader / writer 2 is provided, for example, at the entrance of a tunnel, and is used when an operator enters (enters) a tunnel and exits (exits) from a tunnel.
When reading, the ID information of the worker is read from the IC card 1 held by the worker. Thus, the ID information of the worker is transmitted to the data management device 3. Also, when the worker exits the tunnel, health data such as the cumulative exposure amount, the cumulative exposure amount, and the cumulative exposure amount for each work site, which will be described later, are recorded on the IC card 1 by the IC card reader / writer 2. I have.

Here, the IC card reader / writers 2 are provided in tunnels in various places, respectively.
The data recorded on the IC card 1 by the C card reader / writer 2 can be read by another IC card reader / writer 2 and can be rewritten (updated). Therefore, even when an operator enters and exits a tunnel in various places, the data of the accumulated exposure amount can be consistently managed.

The data management device 3 is provided, for example, on the ground or the like. When the worker enters or leaves the mine, the worker enters or exits the mine according to the ID information of the worker transmitted from the IC card reader / writer 2. , And the entrance and exit time. In addition, the data management device 3 calculates the entry time of the worker from the difference between the entrance and exit times, and based on the entry time and the data of the dust concentration obtained by the concentration management means 8, the worker enters the mine. In addition to calculating the cumulative exposure of the dust exposed in the tunnel between the time of excavation and the time of excavation, the data is managed for each worker.

Here, the calculation of the integrated exposure amount will be described. The integrated exposure amount may be simply obtained by multiplying the worker's admission time and the dust concentration.For example, the predetermined time after entry and the predetermined time before exit are subtracted from the entry time. Correction may be performed. Although the dust concentration gradually changes with time, the dust concentration is measured by the concentration measuring means 4 at any time, and the data of the dust concentration is averaged per unit time (for example, 1 hour, 30 minutes, etc.) by the concentration managing means 8. Values are managed in real time. Therefore, by using the data of the dust concentration managed by the concentration management means 8 (for example, by summing the product of each unit time of the entrance time and the dust concentration corresponding to each unit time). Accumulated exposure can be calculated accurately.

Further, even in the same tunnel, the dust concentration differs depending on the work area. For this reason, the data management device 3 grasps the worker's work area from the worker's ID information obtained at the time of entry into the mine, and as a result the dust concentration to which the worker is exposed, Is determined to be used. Therefore, a work program for each worker is input to the data management device 3 in advance, and by specifying the worker, the data management device 3 can determine in which area this worker will work. It is desirable to keep.

In addition, the data management device 3 calculates the worker's cumulative exposure amount by adding the current cumulative exposure amount to the cumulative exposure amount up to the last time when the worker exits the mine, This is managed for each worker. That is, when a plurality of cycles from the entrance to the exit are performed, the accumulated exposure amount obtained by accumulating the accumulated exposure amount in each cycle is managed.

In some cases, it is necessary for an operator to manage the history of the exposure amount for each work site, in addition to the cumulative exposure amount, which is the total exposure amount that has been exposed. For that purpose, at the time of the worker's unloading, the data management device 3 calculates the cumulative exposure amount for each worker's work site by adding the current cumulative exposure amount to the cumulative exposure amount in the same tunnel,
This is managed for each worker. That is, among the cumulative exposure amounts, the cumulative exposure amount for each work site for each work site is data-managed. For example, the cumulative exposure data for each work site is managed in such a manner that the cumulative exposure amount for each work site at the work site A is a and the cumulative exposure amount for each work site at the work site B is b. Have been.

Further, the health data such as the integrated exposure amount, the cumulative exposure amount, and the cumulative exposure amount for each work site are managed by the data management device 3 and also recorded on the IC card 1. These data are calculated and transmitted to the IC card reader / writer 2.

The health data managed by the data management device 3 can be used on the Internet 9 by, for example, inputting a password. Therefore, when the data such as the cumulative exposure amount of the worker is updated by the data management device 3 provided on (on the ground of) any of the tunnels, the data management device provided on (on the ground of) another tunnel. 3, etc., this data can be obtained and used. That is, the data is shared by the data management devices 3 of the plurality of work sites. Here, the sharing of data is not limited to within the same company, but may be sharing between companies.

Next, a worker management method according to the present invention using the above-described worker management system 1 will be described with reference to FIG.

Further, the data of the dust concentration measured by the dust concentration measuring means 4 provided for each section in the tunnel is managed in real time by the concentration managing means 8, and the work is performed by reading the IC card 1. Since the worker's work area is specified and the dust concentration received by the worker is recognized, the integrated exposure amount can be accurately calculated using the data of the dust concentration received by the worker per unit time.

In addition, since the IC card reader / writer 2 is provided at each work site in each place and can consistently manage the cumulative exposure data, even if the worker goes in and out of the work site in each place, Data can be managed on the cumulative exposure of individuals. In addition, since the cumulative exposure amount for each work site among the cumulative exposure amounts is data-managed, data management is performed such as whether only a is exposed at the work site A and only b is exposed at the work site B. For example, in a pneumoconiosis lawsuit or the like, it is possible to clarify which company is responsible for what percentage.

Further, since the data is shared between the data management devices 3 at each work site, the data management device 3 at any work site can collect data on the cumulative exposure amount for each worker and the cumulative exposure amount at each work site. Can be used.

In the above embodiment, data on the amount of dust exposure is managed for the worker in the tunnel. However, the present invention is not limited to this.
