Description

  The present invention relates to an entrance / exit management system that is managed by controlling an electric lock that unlocks and unlocks a door when entering or exiting a building or each room.

  In recent years, in a building such as an apartment, an entrance / exit management system for electrically unlocking and unlocking an electric lock installed on a door has been widespread in order to manage entrance / exit. Then, it is possible to automatically determine the abnormality of the driving part of the internal mechanism of the electric lock, display and notify the content according to the content of the failure, and to have the self-diagnosis function for detecting the operation abnormality of the electric lock. A lock system has been proposed (see, for example, Patent Document 1).

JP 2003-97107 A

However, even if an abnormal operation of the electric lock is detected and the electric lock is replaced with a new one, if the door is not installed properly, the replaced electric lock does not work properly and the lock cannot be unlocked. There is. In such a case, since it becomes impossible to lock and unlock the door, there arises a problem that the security of the section where entrance / exit is managed and security is secured is lowered.
Further, when the entire system is viewed, there is a problem that the time required for setting is prolonged when there is little know-how for setting the time from the confirmation of door closing to the start of locking.

  An object of the present invention is to provide an entrance / exit management system that detects a change in characteristics associated with a failure of a device related to door unlocking and unlocking and predicts an abnormality.

The entrance / exit management system according to the present invention is an entrance / exit management system in which an electric lock that unlocks and unlocks a door that opens and closes an entrance / exit of a section in which entrance / exit is managed is controlled by an electric lock control panel. When the door lock signal is transmitted, the lock signal is transmitted when the locking of the electric lock is completed, and the electric lock control panel receives the door close signal every time the door is closed. Lock time measuring means for measuring the time to receive the lock time, average value calculating means for calculating the average value of the lock times over a predetermined number of times, and when the average value exceeds a preset threshold value Abnormality prediction means for predicting and issuing an abnormality of the door or the electric lock .

  The effect of the entrance / exit management system according to the present invention is that the locking time is measured from when the door is closed until the electric lock is locked, and is compared with a predetermined threshold value. Therefore, preventive maintenance can be performed on the door, the electric lock, and the electric lock control panel.

The entrance / exit management system according to Embodiment 1 of the present invention is a door 1 arranged at the entrance / exit of a section where entrance / exit is managed, for example, the entire building, each room in the building, etc. Lock (E) 2, Card reader (CR) 3 deployed on the exit side of the entrance, Electric lock control panel (IDC) 4 for controlling the electric lock 2, Entrance / exit management panel (PC) for managing entrance / exit throughout the building ) 5 is provided.

  The door 1 is opened by being pushed or pulled by a person when the electric lock 2 is unlocked, and is closed by a door closer (not shown) when the pushing or pulling force is removed. As shown in FIG. 2A, when the door 1 is closed and the door 1 enters a predetermined range, the level of the door open / close signal changes from “door open” to “door closed”. A door open / close sensor 7 is provided in which the level of the door open / close signal changes from “door closed” to “door open” when the door 1 is opened and the door 1 is out of a predetermined range. When the level of the door open / close signal changes from “door open” to “door close”, it is referred to as a door close signal being transmitted.

The electric lock 2 unlocks and unlocks the door 1 by a dead bolt (not shown) protruding or retracted by the unlocking / unlocking output from the electric lock control panel 4.
As shown in FIG. 2B, the electric lock 2 changes the level of the unlocking signal from “locking” to “unlocking” when the deadbolt is pulled and the position of the deadbolt is within a predetermined range. When the deadbolt is projected and the position of the deadbolt is out of a predetermined range, the level of the unlocking signal is changed from “unlocked” to “locked”. Note that when the level of the unlocking signal changes from “unlocked” to “locked”, it is said that the unlocking signal is transmitted.

  As shown in FIG. 3, the electric lock control panel 4 is an electric lock rotation / unlocking means 11 for changing the rotation / unlocking output to rotate / unlock the electric lock 2, and a lock for obtaining a lock time every time the door 1 is opened / closed. A time measuring means 12, an average value calculating means 13 for obtaining an average value of the locking time every predetermined number of opening / closing times, an abnormality predicting means 14 for predicting an abnormality of a part related to locking / unlocking every time an average value is obtained, Threshold updating means 15 for updating the threshold value used for the storage, and storage means 16 for storing the average value of the obtained locking times and the upper limit value of the locking times.

  As shown in FIG. 2 (c), the electric lock rotation / unlocking means 11 changes the level of the unlocking / unlocking output from “locking” to “unlocking” based on the unlocking command from the entrance / exit management panel 5. When the door open / close signal level from the door open / close sensor 7 changes from “door open” to “door close”, the level of the unlocking output is changed from “unlocked” to “locked” when a predetermined waiting time has elapsed. Change.

As shown in FIG. 2, the lock time measuring means 12 starts and stops the unlocking signal level from the time when the door opening / closing signal level changes from “door open” to “door closed”, as shown in FIG. The time from when “unlocked” changes to “locked” is counted, and the time for locking is obtained and stored in the storage means 16.
The average value calculating means 13 calculates the average value of the locking time for opening / closing the determined number of opening / closing operations, and stores the calculated average value in the storage means 16.
The anomaly prediction means 14 predicts an anomaly by predicting an anomaly of the part related to the unlocking / unlocking, for example, the deterioration of the door erection and the deterioration of the electric lock when the obtained average value exceeds a predetermined threshold value. I will inform you.
The threshold updating means 15 compares a value obtained by multiplying the obtained average value of the locking times by a predetermined coefficient, for example, 1.4, for each predetermined number of opening / closing times with a threshold set at the present time, When the value of 1.4 times the average value of the time is less than the current threshold value, the threshold value is updated with a value 1.4 times the average value of the locking time.

  When a new electric lock control panel 4 is installed in the existing electric lock 2 or the new electric lock 2, a sufficiently large threshold value is set and updated to an appropriate threshold value by starting operation. Yes.

The card reader 3 takes in personal identification information of a person who is permitted to enter or leave the building or room, for example, a personal identification number, biometrics, etc., and sends it to the entrance / exit management board 5.
The entrance / exit management board 5 performs personal authentication based on the personal identification information sent from the card reader 3 and determines whether or not entry / exit is possible. Then, the entrance / exit management panel 5 sends an unlocking command to the electric lock control panel 4 when the entrance / exit is permitted as a result of the personal authentication.
Moreover, the entrance / exit management board 5 takes in the average value of the locking time concerning each door 1 from the electric lock control board 4 included in the building in charge of management, and based on this, the state of the unlocking / unlocking portion of each door is determined. Report to building owners regularly or irregularly.

  The electric lock 2 locks the door 1 by a dead bolt projecting into a strike (not shown) provided on the door 1 side, but the distortion over time of a pillar (not shown) supporting the door 1, Due to various factors such as deformation of the support portion of the door 1 and loose mounting of the electric lock 2, the dead bolt competes with the strike or rubs, thereby increasing the locking time. However, since the electric lock 2 is not yet locked at this stage, no abnormality is reported at this stage even if it is detected that the electric lock 2 cannot be locked as in the prior art.

  On the other hand, in the entrance / exit management system according to the first embodiment of the present invention, the lock time from when the door 1 is closed until the electric lock 2 is locked is measured and compared with a threshold value reflecting the above-described steps. Since it is possible to predict that the part related to locking / unlocking is likely to become abnormal, the door 1, the electric lock 2, and the electric lock control panel 4 can be prevented and maintained.

  In addition, since the threshold used for detecting anomalies can be set to a large value at the start of operation and converged to an appropriate value by operation, operation can be started smoothly and the difference between machine differences is not considered separately. You can do it.
