Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an entrance / exit management system using an IC card, and more particularly to an entrance / exit management system in an area where the occupancy time needs to be managed.
[0002]
[Prior art]
In recent years, along with the development of technologies for information recording media such as IC cards, entrance / exit management systems using these have been proposed (see, for example, JP-A-11-191188). This entry / exit management system not only manages entry using an IC card as an identifier, but also manages the occupancy status of the room by setting the occupancy limit time, occupancy time limit or occupancy limit. . For example, if the area to be managed is a freezer, a resident time limit is set for each area, and entry / exit management is performed if there are occupants who have been in the room even if this resident time limit is exceeded. The system regards it as abnormal, sounds a buzzer to notify the operator, and in some cases reports to a security company. Even if the number of people who can stay in the room is set, if there is an entry exceeding the set number of persons, an abnormality will be reported by a buzzer sounding.
[0003]
[Problems to be solved by the invention]
On the other hand, if the area to be managed is a special environment such as radiation, gas, or high pressure (an area having such an environment is called a “critical area”) and the influence of the environment on the human body changes with time as a parameter, It is necessary to manage the occupant's current and past occupancy time. However, the conventional entrance / exit management system can only manage the current status of the room subject to entrance / exit management, such as the time limit for staying or the number of people allowed to stay in the room. In addition, he had to manage his personal entry history and occupancy time by referring to the elapsed time since entering the room.
[0004]
The present invention has been made in order to solve the above-described problems, and affects not only the current situation of rooms and buildings, but also the influence of those who know from the entry / exit management area for each individual person entering the room. It is an object of the present invention to provide an entrance / exit management system capable of managing entrance / exit in consideration of the above.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, an entrance / exit management system according to the present invention is an entrance / exit management system for managing entrance / exit into an area having a predetermined environment, and a recording medium for recording various information of the owner Based on the information read / written by the reader / writer from the recording medium, a residual element value that increases with exposure to a predetermined environment with time and decreases with time by isolation is calculated based on information read from the recording medium by the reader / writer. And determining means for determining whether or not the owner can enter the area based on this value. According to this entrance / exit management system, the control means calculates the residual element value for each owner of the recording medium. Note that this residual element value is a numerical value that can affect the body by breathing, skin contact, pressure, etc. due to a specific extracorporeal environment such as radiation, gas, high pressure, etc., and that the effect attenuates over time. Means that. The “various information” of the owner means an ID for identifying an individual, a time of entry / exit, a residual element value at the time of entry / exit, personal information described later, and the like. Further, the “information” that is the basis for calculating the residual element value means the entry / exit time, the residual element value at the time of entry / exit, personal information described later, and the like.
[0006]
In the above entry / exit management system, when the owner is allowed to enter the area, the reader / writer writes the residual element value calculated by the judging means and the owner's entry time to the recording medium, and the door at the entrance of the area is opened. You may make it further provide the control means to lock. According to this entry / exit management system, the entry time and the residual element value at the time of entry are written in the recording medium possessed by the individual permitted to enter.
[0007]
In the entry / exit management system, the control means calculates a residual element value based on information read from the recording medium by the reader / writer when the owner leaves the area, and calculates the residual element value and the leaving time in the room. The reader / writer may write on the recording medium, and the door at the exit of the area may be unlocked. According to this entrance / exit management system, the exit time and the residual element value at the exit are written on the recording medium possessed by the exiting individual.
[0008]
The entry / exit management system further includes a central monitoring device for managing the control means, and the control means calculates the available time based on information recorded on the recording medium when the owner of the recording medium enters the room. Then, the central monitoring device may issue an alarm based on the available time in the room. In the present invention, the alarm may be issued either inside or outside the area.
[0009]
In the entry / exit management system, the recording medium may record the personal information of the owner, and the control means may calculate the residual element value and the occupancy time with reference to the personal information. Personal information is information that varies depending on the individual, such as age, sex, and weight.
