JPH05118171A - Locking check displaying system - Google Patents

Abstract

PURPOSE:To check the whole state of locking a door and a window at a glance as keeping confidentiality. CONSTITUTION:A locking sensitive switch 1 for checking a locking state is installed in each of door frame parts. There is provided a switch control part 10 which detects a state of this locking sensitive switch 1 and displays it in a centralized manner. At this switch control part 10, a keyed main switch 2 effectuates a normal monitoring of this locking check sensitive switch 1. A logical circuit A3 is formed so as to make the state monitoring of the switch 1 comes to effective at a time when the main switch 2 is in a state of being turned on. A lamp A4 is lighted when it is locked. Other logical circuits B5, C6 detect a fact that all locking sensitive switches 1 are in a state of being turned to ON, thereby lighting a lamp B7. Each output of all locking sensitive switches 1 and the logical circuit B5 is transferred to the outside via an external terminal 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security system, and more particularly to a lock confirmation display system used for confirming the locked state of doors and windows.

[0002]

2. Description of the Related Art Conventionally, this type of security system has an expensive and large-scale system configuration using a plurality of video cameras, lines, monitor televisions and the like.

[0003]

In the above-mentioned conventional system, it is necessary to construct a large-scale system even when confirming the locked state, and when the system cannot be constructed, a person has a plurality of purposes. There is a problem that it is not possible to check the whole thing at a glance or to check it from the outside, only to go to the ground and check it directly.

[0004]

A lock confirmation display system of the present invention includes a lock detection switch for confirming a locked state, which is provided in each door frame portion or a lock portion of a key of a window.
The lock detection switch is provided on the control panel that detects the state of the lock detection switch and displays it in a centralized manner. A first detection display unit which is formed so that the state monitoring is effective and is displayed when in the locked state; and a second detection display unit which detects and displays that all the lock detection switches are in the ON state. , All the lock sensing switches and an external terminal for transferring the output of the second detection display unit to the outside.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram of an embodiment of the present invention.
A lock detection switch 1 such as a micro switch is installed on the door frame portion corresponding to the lock portion of the door. Main switch with key 2
The logic circuit A3 is formed so that the state of the lock detection switch 1 becomes valid when the switch is in the ON state. The lamp A4 displays the state of the logic circuit A3, and lights up when the keyed main switch 2 is turned on with the door locked.
When the lock detection switches 1 installed on all doors are in the ON state (the doors are locked), the lamp B7 lights up via the logic circuits B5 and C6. Further, the outputs of the lock detection switch 1 and the logic circuit B5 are connected to the external terminal 8
Connect to.

A lamp confirmation switch 9 for checking lamps A4 and B7 for lamp burnout is also installed in the switch control section 10 for intensively detecting and displaying the state of the lock detection switch 1.

In this embodiment, the case where the number of switches for detecting the lock is two (when the switches are installed on two doors) has been described.
It is clear that a similar display system can be constructed even if more than one switch is installed.

In the case of a window, a lock detection mechanism may be provided in the lock portion of the key or the like and the switch control portion 10 can be informed.

A similar display system can be constructed by using a matching circuit corresponding to a magnetic card or an IC card instead of the keyed main switch 2.

[0011]

As described above, according to the present invention, it is possible to check the lock at a low cost by installing the lock detection switch on the door or the window. Further, since the control panel is provided at one location and the main switch with a key is provided on this control panel, only the person concerned can check the locked state and the confidentiality can be maintained.

By using the external terminal, it is possible to remotely transmit the lock information through a telephone line or the like.
