Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a building entrance/exit management device using a computer.

(Conventional technology) A building entrance/exit management device is a device that manages traffic at the building's side entrance and unattended management of the keys of each tenant.It uses a magnetic card to unlock the electric lock of the side entrance and Open and close the key box where the key is stored.

The electric doorway unlocking function outputs an unlocking command only to the registered card when a magnetic card is inserted from the outside into a magnetic card reader installed at the side door.

The key box opening/closing function outputs an opening command to the key box in which the tenant key corresponding to the registered card is stored when a magnetic card is inserted into a magnetic card reader attached to the key box.

Therefore, a building resident can automatically take out and return the tenant's key when arriving and leaving work using a magnetic card.

Tenant buildings these days have equipment such as air conditioning, lighting, and elevators, and often have dedicated controllers installed to save labor and energy.

Such tenant buildings require both tenant key management and equipment management such as air conditioning and lighting.

Conventionally, dedicated controllers have been installed for managing tenant keys and equipment such as air conditioning and lighting, which not only requires double investment in equipment, but also is troublesome in terms of operation and maintenance. Met.

(Problems to be Solved by the Invention) The present invention focuses on the fact that there is a certain relationship between the arrival and departure times of building residents and the starting and stopping times of air conditioning, lighting, elevators, etc. The aim is to provide a rational building entrance/exit control device that incorporates automatic control of air conditioning, lighting, elevators, etc.

[Structure of the invention]

(Means and effects for solving the problem) The building entrance/exit management device according to the present invention includes a key box in which the keys of each tenant in the building are stored, a means for inputting signals from a magnetic card, and a magnetic card. A means for outputting an open command to the corresponding key box in response to a signal from the card, a means for inputting the state of the key switch installed in the key box, and a means for inputting the state of the key switch (key removal/return state). The air conditioner is equipped with a means for outputting an external control signal by controlling the air conditioner to correspond to each tenant in conjunction with the timing of the take-out and return of the tenant's key.

This system automatically controls lighting, elevator start/stop, and elevator stop floor control.

(Example) An embodiment of the present invention is shown in FIG.

In FIG. 1, numeral 10 is the controller of the entrance/exit control device, which is a central processing unit! (hereinafter referred to as CPU) 11. 3-channel serial interface device (hereinafter referred to as SIF) 12A, 12B, 12C, digital input device (hereinafter referred to as DI) 13. and a relay output device (hereinafter referred to as RO) 14.

The SIF 12A operates as an interface for the printer 22, and the SIFs 12B and 12C operate as interfaces for the magnetic card readers 15A and 15B, respectively.

Magnetic card readers 15A and 15B each have side port 2.
0 and the key box 16, and the magnetic card reader 1
Data from 5A is sent to CPU 1 via SIF 12B.
1 to judge whether the registered card is correct or not.

The key box 16 is a collection of boxes in which the keys of each tenant are stored, and a key switch and a magnet coil are installed in each box.

The state of the key switch is sent to the CPU 11 via DI 13.
is input, and the key of each tenant is extracted in CPt111.
The return status is determined.

On the other hand, the magnet coil operates via the RO 14 in response to a command from the CPU 11, and unlocks the key box to open the key box, making it possible to take out or return the key.

17 is an air conditioner, 18 is a lighting, 19 is an elevator,
Each is controlled via the RO 14 by commands from the CPt 111, and each operating state is input to the CPU 11 via the [) 113.

22 is a printer that records the key switches in each box of the key box 16, the air conditioner 17, the lighting 18, and the status of the elevator 19;
tt. Further, 21 is an electric lock provided at the side door 20, which operates via the RO 14 in response to a command from the CPU TT.

Next, the operation at the time of entering the museum according to the present invention will be explained with reference to the flowchart shown in FIG.

When building residents enter the building, they enter their cards into the magnetic card reader 15 attached to the side entrance, and if the cards match, the electric lock 21 at the side entrance is unlocked by a command from the controller 10. You will be able to enter the building.

Next, a magnetic card reader 15 attached to the key box
When the same tenant's card is entered into the tenant, and the cards match, the controller 10 outputs an opening command to the key box 16 corresponding to the resident, and the tenant's key stored in the key box 16 can be taken out. Become.

When the key box is opened, the key switch installed in the key box 16 operates, and the controller 10 determines that the key has been removed, and the air conditioner 17 of the corresponding tenant is activated.
When the person enters the building for the first time, the elevator 19 is activated and the stop lock of the corresponding floor is released.

In addition, if you are not the first person to enter the building, we will only unlock the relevant floor, and if the magnetic cards do not match when entering the building or when taking out the tenant's key,
An alarm is issued and the error is handled by printing on the printer 22.

FIG. 3 is a flowchart showing the operation when leaving the building. When leaving the building, a resident of the building first inputs his or her card into the magnetic card reader 15 attached to the key box 16.

If the cards match, the controller 10 outputs an open command to the corresponding key box 16, and therefore the tenant's key can be returned to the key box 16.

At this time, the key switch installed in the key box 16 enters the returned state, and the controller 10 determines that the key has been returned and stops the corresponding air conditioner 17, turns off the light 18, and If the keys of all tenants on the floor have been returned, the elevator 19 is prohibited from stopping on that floor.

Further, when the keys of all tenants of the building are returned at the final exit, the elevator 19 is completely stopped.

Furthermore, error processing in the case of a mismatch in magnetic card verification is performed in the same way as when entering the museum.

〔Effect of the invention〕

As explained above, according to the present invention, an entrance/exit management device that uses a magnetic card to manage entrance to a building's side entrance and unattended management of tenant keys can be used to retrieve each tenant's key,
By incorporating a means to input the return status and a means to control the air conditioning, lighting, elevators, etc. in the building, it is possible to unattended management of the keys of each tenant in the building and at the same time air condition the building at the time of arrival and departure.

Since it is possible to automatically control lighting, elevators, etc., it is possible to realize a rational building entrance/exit control device that is excellent in operability and maintainability, and is also advantageous in terms of labor and energy savings.
