JPH05231053A - Detecting and alarming circuit for abnormality of electric lock, in electric lock controlling and monitoring device - Google Patents

Abstract

PURPOSE:To constitute a cheap abnormality detecting circuit by constituting a series circuit between a first relay contact for detecting a locking and unlocking control signal delivered to an electric lock, and a second relay contact for detecting a locking and unlocking condition signal from a key. CONSTITUTION:When a manipulation switch S1 is depressed so as to be turned on, a relay X1 is energized so that a relay contact x1 is opened. Then, a relay Y1 is deenergized so that relay contacts y21, y11 are opened, and further, a voltage delivered to an actuator BS1 is cut off so that an electric lock B1 is unlocked. When a door is opened, a status switch BP1 is turned on so as energize a relay G1, and accordingly, a light emitting diode D1 is lit on. In such case that the lock cannot be locked since the switch S1 is turned off even though the switch S1 is depressed for locking the lock, the switch BP1 is continuously turned on. Further, the relay contacts y21, y11, g21, g11 are closed, and an emergency ball F issues an alarm while a diode E1 is lit on so as to indicate occurrence of an abnormality of the electric lock B1.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock abnormality detection / informing circuit of an electric lock control and monitoring device.

[0002]

2. Description of the Related Art An electric lock control / monitoring device centrally controls and monitors the locking / unlocking of electric locks provided in many places. The electric lock control / monitoring device locks / unlocks each electric lock. An output circuit for transmitting a lock control signal and a receiving circuit for receiving a locked / unlocked state signal from each electric lock are provided. And
The electric lock control and monitoring device uses the central processing unit (CPU) of the electric lock control and monitoring device to detect each electric lock from the output state of the output circuit to each electric lock and the reply state of the lock / unlock status signal from each electric lock. Abnormality is detected and reported.

That is, the central processing unit (CPU) of the electric lock control and monitoring device constantly controls the control output state from the electric lock control and monitoring device to each electric lock, and also monitors the reply state from each electric lock. And even if the lock control output is output to the electric lock, the reply state is the unlocked state,
If the control circuit of the electric lock has failed, or the electric lock may be destroyed by a suspicious person and a thief may enter, an emergency bell is sounded and which electric lock is abnormal is displayed. It was

[0004]

By the way, in the electric lock control and monitoring device for detecting and notifying the abnormality of the electric lock by using the central processing unit (CPU) as described above, the price becomes expensive, and the control is performed. If the number of electric lock lines to be monitored is small, the price per line becomes too expensive.

The present invention has been made in order to solve the above problems, and an object thereof is to detect and notify an abnormality of an electric lock with an inexpensive structure when the number of lines of the electric lock is small. An object of the present invention is to provide an abnormality detection / informing circuit for an electric lock of an electric lock control and monitoring device which can be balanced in terms of cost.

[0006]

In order to solve the above problems, the present invention transmits a locking / unlocking control signal to each electric lock and receives a locking / unlocking state signal from each electric lock. In the electric lock abnormality detection notification circuit of the electric lock control monitoring device, which performs centralized control monitoring of each electric lock and detects and notifies the abnormality of the electric lock from the disagreement between the lock / unlock control signal and the lock / unlock status signal. , A first relay for detecting a locking / unlocking control signal to the electric lock and a second relay for detecting a locking / unlocking state signal from the electric lock are provided, and a contact of the first relay and a second relay
It is characterized by forming a series circuit with the contacts of the relay and detecting and notifying the abnormality of the electric lock.

[0007]

With the above-mentioned structure, the first relay turns on the contact by the lock signal to the electric lock, and the second relay turns on the contact by the unlocking state signal from the electric lock. Therefore, when an abnormality occurs in the electric lock in which the status signal from the electric lock is in the unlocked state even though the locking control signal is output to the electric lock, the contact of the first relay and the second relay The series circuit with the contact is turned on to detect and notify the abnormality of the electric lock.

By the way, for example, the operation switch S₁Press
The operation switch S₁Is turned on, relay X₁
Is excited and relay contact x₁Turn off. Then the relay
Y₁Demagnetizes the relay contact y_{twenty one}And relay contact y₁₁And
And actuator B_s1The voltage to is cut off
It Then, electric lock B₁Can be unlocked and the door can be opened
Will be able to Therefore, the operation switch S₁Turned on
Electric lock B while₁When you open the attached door,
Can be opened status switch B_P1Turns on. Then,
Relay G₁Is excited and the light emitting diode D₁Is a point
Light, electric lock B ₁Display that the door of has been opened. Well
At the same time, relay contact g_{twenty one}And relay contact g₁₁Is on
But relay contact y_{twenty one}And relay contact y₁₁And off
The emergency bell F does not ring and the light emitting diode
Do E₁Is off.

By the way, the operation switch S₁Press again
Operation switch S₁(Operation switch S _1,... S_nEvery time you press
Push button switch that turns on and off is turned off
State X₁Demagnetized and returned to its original state
, Electric lock B₁Actuator B_s1Voltage is applied to
And electric lock B₁Is locked and the door cannot be opened
Becomes However, if the electric lock B₁Failure due to
Data B_s1Voltage is not applied to the
Actuator B_s1Does not work, electric lock B
₁Can be opened without being locked, and if the door is
When opened, the electric lock control and monitoring device A becomes electric lock B.₁Locking system
Electric lock B despite outputting the signal₁from
The status signal is unlocked, that is, status switch B_P1
Occurs when is on. Then relay contact y_{twenty one}When
Relay contact y₁₁And relay contact g_{twenty one}And relay contact g₁₁And
When both are turned on, the emergency bell F rings and the light emitting diode

The airlock control monitoring device A notifies the detection.

In the embodiment, if the stop switch H is turned off, the abnormality bell F that is ringing upon detection of the abnormality can be stopped.

[0019] As described above, the electric lock control and monitoring apparatus A is the electric lock B ₁ of the present _invention, the ... B _n abnormality, relay Y ₁ and the contact of the relay G _1, relay Y ₂ and relay G ₂ By connecting the contacts with and the contacts of the relay Y _n and the relay G _{n in} series, detection and notification can be easily performed without using a central processing unit (CPU).

The present invention is not limited to the embodiments.
Not when the electric lock actuator is energized
