Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a field worker management system for managing the entry and exit of each site worker to and from a building site based on a personal information card given to the site worker.

[0002]

[Prior Art] At a construction site, starting from foundation work, installation work, woodwork work, cloth work, electrical work, water supply work,
Since various works such as gas work are carried out, many site workers involved in these works will move in and out.
The management of such a large number of site workers is usually performed by the site supervisor, and the site supervisor also usually communicates the management status to the head office and the vendors.

In this case, as a method of contacting the head office or a trader, a method in which a site supervisor or the like makes a call from a nearby public telephone box is generally used. At a construction site where there is no public telephone box nearby, JP-A-1
As described in Japanese Patent Laid-Open No. 94161, a method has been proposed in which a wireless conversation device is carried and wireless communication is performed by the wireless conversation device. Further, a method of contacting by a facsimile machine installed in the nearest office is also considered.

[0004]

However, in any case, it is a contact by a specific person called a field supervisor,
Also, the site supervisor is not responsible for only one construction site, but is responsible for multiple construction sites and monitors the progress of work at each site while patroling these construction sites. Therefore, the management situation of each construction site (for example,
The situation of the on-site workers entering and leaving the house) has to be communicated regularly (for example, at the end of the work day) at once.
There was a problem that the head office, etc. could not grasp the management status of each construction site in real time. This causes a problem that if a trouble occurs at some construction site when there is no on-site supervisor, it cannot be immediately dealt with.

Further, since the management status communication is a telephone communication, a wireless communication, or a communication by a facsimile machine,
It may not always be possible to make an accurate contact due to a contact mistake or forgetting to contact the reporter, or a hearing mistake on the part of the listener or forgetting what was heard. Even if they are contacted correctly, mistakes such as mistaken input when inputting this into the computer are likely to occur.

The present invention was devised to solve such problems, and an object thereof is to provide a field worker management system capable of accurately managing the entering and leaving of a field worker in real time. .

[0007]

In order to solve the above-mentioned problems, the on-site worker management system of the present invention comprises a terminal installed at a construction site and having an information reader device connected to a telephone line, and an on-site worker. The personal information card is provided with an identification code assigned to each, and a host computer installed in the management office and connected to the terminal through a telephone line, and the personal information card when entering or leaving a building site. By reading the identification code of No. 2 by the information reader device, the host computer manages the entrance and exit of the site worker.

The personal information card used in the present invention includes a bar code card in which an operator's identification code is printed as a bar code, a magnetic card in which the identification code is provided as a magnetic code, a card in which the identification code is formed as a hole, and an unevenness The personal information of the worker is represented by these cards.

According to a second aspect of the present invention, there is provided a field worker management system according to the present invention, wherein a terminal is installed at a construction site and has a bar code reader connected to a telephone line, and an identification code assigned to each field worker is a bar code. The personal information card printed as a code and a host computer installed in the management office and connected to the terminal through a telephone line are provided, and the identification code of the personal information card is entered into the bar when entering or leaving a building site. By reading with a code reader, the host computer manages the entrance and exit of the site worker.

According to a third aspect of the present invention, there is provided a field worker management system according to the present invention, wherein a terminal installed at a construction site and having a magnetic code reader connected to a telephone line, and an identification code assigned to each site worker are magnetic. It is equipped with a personal information card given as a code and a host computer installed in the management department and connected to the terminal through a telephone line. By reading with a code reader, the host computer manages the entrance and exit of the site worker.

[0011]

Operation: The site worker reads the personal information card given to him by the information reader device before entering the building site. The read data is input to the host computer of the management office through the telephone line and held as data.

As a result, in the management department, it is possible to accurately manage the residence time, the number of people, etc. of each site worker in real time.

Also, when the site worker finishes the work and leaves the house, he leaves the house after reading the personal information card with the information reader device. This data is input to the host computer of the management department through the telephone line and held as data.

As a result, the management office can accurately manage the leaving time and the number of people leaving each site worker in real time.

According to the second aspect of the invention, the site worker enters the building site after reading the personal information card given to him by the bar code reader. The data read by this bar code is input to a host computer installed in the management office through a telephone line and held as data. As a result, in the management office, it is possible to accurately manage the residence time and the number of residents of each site worker in real time.

Also, when the site worker finishes the work and leaves the house, he or she leaves the house after reading the personal information card with the barcode. The data read by this bar code is input to a host computer installed in the management office through a public telephone line and held as data. As a result, in the management office, it becomes possible to accurately manage the leaving time and the number of people leaving each field worker in real time.

In the invention of claim 3, the bar code and the bar code reader of claim 2 are replaced by a magnetic code and a magnetic code reader, and the same operation as the invention of claim 2 is achieved.
