Description

  The present invention is a consignment receiving device installed in an entrance of a detached house or an apartment house, an office, a leisure facility, or the like, and includes an electric lock used for temporarily storing a delivered item or a luggage. The present invention relates to a receiving device.

Conventionally, in a load receiving device that locks and unlocks a door with an electric lock, there is a type that is automatically locked when a predetermined operation is performed and the door is closed, and the door can be locked without performing a locking operation with a key or the like. Because it is locked, you can prevent forgetting to lock. However, humans and animals may be trapped in the warehouse of such a type of receiving apparatus.
Therefore, there is a method of providing an emergency mechanical lever inside the door of the cargo receiving device or a weight sensor provided on the floor surface in the warehouse, detecting the displacement, and automatically unlocking the electric lock.
However, when an emergency mechanical lever is provided, there is a problem that the number of parts increases and the mechanism becomes complicated, and when a small animal such as a cat is confined, it cannot be opened. In addition, when a weight sensor is used, since it is necessary to provide a movable bottom plate on the floor in the warehouse, there is a possibility that unintended load fluctuations such as the load slipping may occur, resulting in erroneous detection.

Therefore, various measures have been proposed for monitoring the situation in the warehouse of the consignment receiving apparatus using a sensor or the like and preventing such a confinement accident.
For example, Patent Document 1 below discloses a cargo receiving device including a human body sensor that detects whether or not an item stored in a warehouse is a human body. According to this, only when the human body detection signal continues to be received after a lapse of a predetermined time since receiving the human body detection signal, when the electric lock is unlocked and the parcel delivery company accommodates the luggage in the warehouse, It is said that the electric lock will not be unlocked unnecessarily by detecting that the human body is trapped in the hand placed in the cabinet when receiving the package stored in the container.
JP-A-6-117154

  However, since the thing of the said patent document 1 starts the time measurement of the said predetermined time regardless of the open / closed state of the door of a cargo receiving apparatus triggered by the time when the first human body detection signal is received, If the door is opened for a long time by taking time to store the luggage in the storage, the predetermined time elapses. In this case, the above-described operation of monitoring and controlling the situation in the warehouse with the human body sensor is completely useless. In addition, even if the predetermined time has not elapsed, if the counting of the predetermined time is started before the door is closed, the remainder of the predetermined time after the door is closed becomes a short time, and the influence when the door is opened is affected. It cannot be excluded and may cause malfunction. In other words, once the door of the cargo receiving device is opened and closed, the interior atmosphere and the outside air atmosphere are mixed, so if there is a temperature difference between them, the temperature atmosphere in the interior will become uneven and the human body sensor will mistake It may be easy to detect. Therefore, it can be said that it is easy to detect errors immediately after the door is closed.

  In this way, if the electric lock is unlocked and the door is opened due to erroneous detection by the sensor, there is a possibility of causing the theft of the delivered goods. Therefore, a more accurate moving object detection is required and a malfunction is not required. .

  The present invention has been made in view of the above circumstances, and is capable of preventing an accident that a moving body such as a human body or an animal is accidentally trapped in a warehouse, and can properly prevent malfunction of automatic unlocking due to erroneous detection. I will provide a.

In order to solve the above-mentioned problem, the consignment device according to the present invention outputs a luggage storage provided with a door having an electric lock, and a detection signal as to whether or not the contents in the storage of the luggage storage are moving objects. An infrared type moving body sensor, a door sensor that detects the open / closed state of the door, and a control unit that automatically unlocks the electric lock when it is determined that there is a moving body based on the detection signal from the moving body sensor. The control unit stops energizing the moving body sensor or invalidates the detection signal by the moving body sensor until a predetermined time has elapsed after the door sensor detects the closed state of the door, The automatic unlocking is not performed .

Moreover, the said control part is good also as what resets the time measurement of the said predetermined time, when the open state of the said door is detected by the said door sensor before the said predetermined time progress.
According to this, when the door is opened while the predetermined time is being measured by a human operation or the like, unnecessary judgment control is not performed while the door is open, and the door is closed again. In this case, since the predetermined time can be counted again, malfunction due to erroneous detection can be prevented.

Furthermore, when the detection signal and non-detection by the moving body sensor are repeated a predetermined number of times after the predetermined time has elapsed, the control unit may determine that there is a moving body and automatically unlock the electric lock.
According to this, it is possible to prevent erroneous detection even when, for example, a luggage having a temperature is accommodated in a relatively cold storage. That is, by not determining that there is a moving object simply by continuing the detection state for a certain period of time, it is possible to distinguish between a high-temperature container and a moving object, and to realize more accurate moving object detection determination.

And a moving body sensor shall be installed in the recess formed in the ceiling or inner wall in a store | warehouse | chamber.
According to this, since it does not interfere with the things in the luggage storage, it is possible to detect well.

According to the cargo receiving device of the present invention, the energization to the moving body sensor is stopped or the detection signal by the moving body sensor is invalidated until a predetermined time elapses after the door sensor detects the closed state of the door. Since automatic unlocking of the lock is not performed, malfunction due to erroneous detection can be prevented with a simple configuration. Immediately after closing the open door as described above, the interior atmosphere and the outside air atmosphere mix, so if there is a temperature difference between them, the interior temperature atmosphere becomes uneven and an infrared motion sensor However, it is easy to make a false detection. Therefore, by not performing automatic unlocking of the electric lock until a predetermined time has elapsed in which the temperature unevenness of the internal temperature atmosphere is eliminated, it is possible to detect an appropriate moving object and prevent erroneous detection. Therefore, malfunction of automatic unlocking due to erroneous detection can be prevented, and a highly secure cargo receiving apparatus can be obtained.
In addition, the control unit stops energizing the moving body sensor or invalidates the detection signal by the moving body sensor until a predetermined time elapses, so that the automatic unlocking operation of the electric lock is stopped during the predetermined time. it can. In particular, if the energization of the moving body sensor is stopped until the predetermined time elapses, the power consumption can be reduced.

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

The consignment receiving apparatus 1 according to the present invention is used to temporarily store and deliver a delivery delivered to an answering house instead of a resident. The consignment receiving device 1 is installed in a part of an entrance hall of an apartment house such as an apartment, and a plurality of consignment receiving devices 1 are combined as shown in FIG.
Since the delivery box A is used jointly by the residents of the apartment house, enter the room number and password so that the delivered items stored in the receiving device 1 will not be delivered to the non-destination residents. Thus, the door 10 can be opened, and the door 10 is locked and unlocked by the electric lock 2 controlled by an electric signal.
It should be noted that the shape, combination, number, etc. of the consignment receiving device 1 constituting the delivery box A are not limited to those shown in the figure.

  The delivery box A includes a plurality of receiving devices 1 having different sizes, a stamping device 15 that can automatically stamp a receipt when a delivery agent puts a non-delivery delivery slip, a setting of a personal identification number, various services being stopped, And a setting device 16 for setting (see FIG. 2). The consignment device 1 includes a box-shaped luggage storage 17 having a front opening in which stored items such as deliverables are stored, a door 10 provided to close the front opening and open and close via a hinge portion 10a, a room Operation keys such as a numeric keypad for inputting a number and a personal identification number, an operation key such as a delivery button and a receipt button are provided, and an operation display unit 11 for displaying whether or not it is empty is provided. The door 10 includes a handle 12 for opening and closing the door 10, an emergency unlocking key portion 13, an electric lock 2 for locking and unlocking the key based on an electric signal, and an open / closed state of the door 10. A door sensor 3 is provided at least. The door sensor 3 can be configured, for example, by providing a limit switch inside the unit of the electric lock 2 or by providing a photoelectric filler sensor in the door 10 or the like.

  In the recess 17aa in the center of the ceiling 17a of the luggage storage 17, a moving body sensor 4 for outputting a detection signal as to whether or not an object in the luggage storage 17 is a moving body such as a human being or an animal is embedded. Thus, if the moving body sensor 4 is embedded and provided, it can detect satisfactorily without interfering with the things in the luggage storage 17. The place where the moving body sensor 4 is provided is not limited to the position shown in the figure, as long as it is provided at a position where it can be easily detected so as not to interfere with the contents. For example, it may be provided on the inner wall as shown by a dotted line in FIG. As the moving body sensor 4, an infrared detection type sensor that detects a heat ray radiated from a human body is preferable.

  The electric lock 2, the door sensor 3, and the moving body sensor 4 are controlled by the control unit 6, and the control unit 6 supplies power from the power source 5 to drive each of the above-described sensors connected by a signal line or the like. Yes. The control unit 6 includes a timer unit 8 that counts various predetermined times described later, and a counter unit 7 that counts the number of detection signal outputs from the moving body sensor 4 according to a predetermined condition. These controls will be described later.

Next, with respect to the method of using the luggage apparatus 1, an example of an operation from when the delivery item is delivered by the delivery company to the resident of the apartment house receiving the delivery item will be described.
The delivery agent selects the empty receiving device 1 by checking the operation display unit 11 in consideration of the size of the delivered item among the receiving devices 1 installed in the delivery box A. The door 10 of the cargo receiving device 1 is opened, and the delivered goods are stored in the luggage storage 17. At this time, it is desirable to place the delivery item in the center of the luggage storage 17 so that the detection by the moving body sensor 4 is good. When a delivery button (not shown) provided on the operation display unit 11 is pressed and the room number of the delivery destination is input, when the door 10 is closed, the door sensor 3 detects that the door 10 is closed, and the electric lock 2 Is activated and locked. At this time, a room number is displayed on the operation display unit 11. When the absent delivery slip is put into the stamping device 15 of the delivery box A, the receipt stamp is printed on the absent delivery slip, and the delivery of the delivery is completed. Thereafter, if the delivery agent posts the absence delivery slip to the delivery destination resident's mailbox, the resident can recognize that the delivery item has been delivered to the consignment device 1.

The resident who has received the absent delivery slip goes to the delivery box A, looks at the operation display unit 11 for the consignment device 1 on which his / her room number is displayed, presses the receipt button (not shown) of the consignment device 1, and Enter the security code assigned to each number. If the entered password is correct, the electronic lock 2 is unlocked. Then, the door 10 can be opened to receive the delivery.
The above-described operation example is merely an example, and if a number is assigned to the receiving device 1 and a predetermined operation is performed, a notification that automatically displays the number, delivery date, etc. of the receiving device 1 that houses the delivery is automatically displayed. It may be printed. Further, when the door 10 is closed, the door 10 may be closed after a lock set button (not shown) provided in the luggage storage 17 is pushed down. Further, after the delivery item is stored in the luggage storage 17, the room number may not be displayed for crime prevention, but a notification of arrival (such as turning on a lamp) may be displayed.

Next, the moving object detection determination method in the luggage storage 17 of the cargo receiving apparatus 1 performed immediately after closing the door 10 that has been opened will be described in detail with reference to FIGS. 1, 4, and 5.
FIG. 1 shows a flowchart (S100 to S106) showing an example of a basic operation immediately after the door is closed. In this flowchart, an example of operation after the door sensor 3 detects that the door 10 is closed after a predetermined operation and the electric lock 2 is automatically locked is described. Further, the door sensor 3 is always supplied with electric power, and can be detected as long as electric power is supplied.
When the door sensor 3 detects the closed state (S100), the timer unit 8 is activated to start measuring a predetermined time (S101). After that, even if the moving body sensor 4 detects a moving body and outputs a detection signal, the output of the detection signal may be erroneously detected while the predetermined time is counted, that is, until the predetermined time elapses. , Invalidate (S102, S103, S104). When the predetermined time has elapsed (S105), the routine proceeds to normal moving body detection determination control in which invalidation control is not performed. The normal moving object detection determination control will be described later with reference to FIGS.
According to this, after the open door is closed, the interior atmosphere and the outside atmosphere are mixed, so if there is a temperature difference between the two, temperature irregularity occurs in the interior temperature atmosphere and the infrared moving object Although the sensor 4 is easily misdetected, if the predetermined time elapses, the temperature unevenness of the internal temperature atmosphere is eliminated. That is, even if the motion sensor 4 outputs a detection signal until a predetermined time during which erroneous detection is likely to occur, the electric lock 2 is invalidated and the electric lock 2 is not automatically unlocked. Can do.
On the other hand, after the door sensor 3 detects the closed state (S100) and starts the timer unit 8 (S101), when the door sensor 3 detects the open state (S102), the timer unit 8 resets the time count ( S106).
According to this, when the door is opened during a predetermined time by the timer unit 8 due to a human operation or the like, unnecessary determination control is not performed while the door 10 is in the open state. When the door 10 is closed again, the predetermined time can be counted again.

FIG. 4 shows an operation state of each sensor (door sensor 3, moving body sensor 4) and an energization state of the moving body sensor 4 when a detection signal is output by the moving body sensor 4 immediately after the opened door 10 is closed. It is a time chart. Here, a predetermined time measured by the timer unit 8 is indicated by T.
The predetermined time T may be set to a sufficient time until the temperature unevenness in the luggage storage 17 is eliminated. For example, the predetermined time T may be about 30 seconds to 50 seconds. If the predetermined time T is less than 30 seconds, there is a possibility that the temperature unevenness in the luggage storage 17 is not sufficiently eliminated, and if the normal moving object detection determination control is started in this state, there is a possibility that the contained item is erroneously detected. is there. On the other hand, if the predetermined time T is set longer than 50 seconds, detection of a moving object confinement accident is delayed.
As shown in FIG. 4, when the door sensor 3 detects that the door 10 that has been opened is closed, the timer unit 8 is triggered by this and a predetermined time T is measured. The energization of the moving body sensor 4 is triggered by the closed state of the door sensor 3.
Even if the energized moving body sensor 4 outputs a detection signal when there is a moving body during a predetermined time, that is, before the predetermined time elapses, the control unit 6 invalidates this and determines that the moving body has been detected. do not do. Then, after a predetermined time has elapsed (after the time is up), normal moving object detection determination control is performed, and when it is determined that there is a moving object, the electric lock 2 is automatically unlocked.

FIG. 5 is a time chart showing a different operation example in the same situation as FIG.
The operation example shown in FIG. 4 is an example in which the moving body sensor 4 is energized using the closed state of the door sensor 3 as a trigger, and even if there is a moving body detection by the moving body sensor 4, it is invalidated within a predetermined time T. However, the operation example shown in FIG. 5 is an example in which energization to the moving body sensor is stopped until the predetermined time T elapses so that the moving body is not detected. The other points are the same as the example of FIG.
As shown in FIG. 5, when the door sensor 3 detects that the door 10 that has been opened is closed, the timer unit 8 is activated using this as a trigger, and the predetermined time T is counted. At this time, since the moving object detection determination within the predetermined time T is unnecessary, power is not supplied to the moving object sensor 4. In FIG. 5, if the moving body sensor 4 is energized, a dotted line indicates that a detection signal is output.
When the timer unit 8 finishes measuring the predetermined time T (time up), that is, when the predetermined time T has elapsed, power is supplied to the moving body sensor 4 and normal moving body detection determination control is performed.
As shown in FIG. 5, if the energization of the moving body sensor 4 is performed while the door sensor 3 detects the closed state and after a predetermined time T has elapsed, useless power supply is eliminated, and power consumption is reduced. be able to.

Subsequently, a normal moving object detection determination method after a predetermined time (T) has elapsed will be described with reference to FIGS.
The example shown here determines that there is a moving object when the detection and non-detection of the moving object sensor 4 are repeated a predetermined number of times.
FIG. 6 shows a flowchart (S200 to S208) showing an example of the basic operation of the moving object detection determination control.
In this flowchart, an example of operation after the door sensor 3 detects that the door 10 has been closed after a predetermined operation, the electric lock 2 is automatically locked, and a predetermined time (T) has elapsed will be described. ing. Further, the door sensor 3 is always supplied with electric power, and can be detected as long as electric power is supplied. In the flowchart, “n” indicates the number of counts by the counter unit 7 and indicates the set predetermined number of times.
When the door sensor 3 detects the closed state (S200) and the moving body sensor 4 detects the moving body (S201), the timer unit 8 is activated to start measuring a predetermined detection time (T1 described later) (S202). First, the moving body sensor 4 determines whether or not the output of the detection signal is continued for at least the predetermined detection time. If the detection signal output is continued for the predetermined detection time or more, this is counted as 1 (S204). , S205). This counting is performed by the counting unit 7.
When the moving body sensor 4 is in the non-detection state, the non-detection predetermined time (T2 to be described later) is measured to determine whether the non-detection time does not exceed the non-detection predetermined time. After that, when the detection signal output by the moving body sensor 4 is continued again for a predetermined detection time or longer, this is counted as 2 (S204, S205). If the non-detection state is entered again and the detection signal output by the moving body sensor 4 continues for a predetermined detection time or more while the non-detection time does not exceed the predetermined non-detection time, this is counted as 3 counts (S204, S205). To do. At the third count (n = 3), the electric lock 2 is unlocked on the assumption that moving objects are stored in the luggage storage 17 (S207).
On the other hand, when the output of the detection signal by the moving body sensor 4 is stopped during the above control (S203), the count in the counter unit 7 is reset.
In this way, when the detection and non-detection of the moving body sensor 4 are repeated a predetermined number of times (here, 3 counts), if it is determined that there is a moving body, for example, a baggage can be stored in a relatively cold baggage having a temperature. Even when housed in the cabinet 17, it is possible to prevent erroneous detection. That is, by not determining that there is a moving object simply by continuing the detection state for a certain period of time, it is possible to distinguish between an object having a high temperature and a moving object, thereby realizing more accurate moving object detection determination.
In addition, after the electric lock 2 is automatically unlocked as a moving object confinement accident occurs, in order to notify a manager or the like of the confinement accident, notification may be performed by turning on a lamp or sounding a siren. Further, a spring mechanism or a motor may be built in the door 10 so that the door 10 automatically opens when the electric lock 2 is unlocked.

FIG. 7 is a time chart showing an operation state of the moving body sensor 4 when the above-described control is performed.
Here, in order to distinguish from the predetermined time (T) described in FIGS. 4 and 5 in which the detection signal by the moving body sensor 4 is invalidated, the predetermined time for measuring the output time of the detection signal by the moving body sensor 4 is detected as the predetermined time T1, The predetermined time for counting the non-detection time will be described as the non-detection predetermined time T2.
The predetermined detection time T1 is set to about 0.4 seconds to 0.7. If it is set smaller than this, the detection output time is too short, so detection itself may cause false detection such as noise.If it is set larger than this, the time until moving object detection determination is performed. It becomes too long, and the grasp of the confinement accident is delayed.
The non-detection predetermined time T2 is set to about 7 seconds to 13 seconds. If it is set to be smaller than this, the counter unit 7 is reset only after a little delay in re-detection by the moving body sensor 4, leading to erroneous detection. If it is set larger than this, the time until the moving object detection determination is made becomes too long, and the grasp of the confinement accident is delayed.
Furthermore, here, an example in which the predetermined number of times to be counted under the predetermined condition is 3 is shown, but the present invention is not limited to this and is set within a range in which the moving object detection determination is not delayed.

The example of FIG. 7 shows a case where T1 is set to 0.5 seconds and T2 is set to 10 seconds.
First, when the detection signal is output by the moving body sensor 4 for 0.5 seconds or more, the count is 1 count, and then the detection signal by the moving body sensor 4 is again 0.5 seconds or more after a non-detection time within 10 seconds. Is output, 2 counts are assumed. Then, it is determined that the moving object is stored in the luggage storage 17 when the detection signal is output again by the moving sensor 4 for 0.5 seconds or more after a non-detection time of 10 seconds or less (moving object detection determination). ), The electric lock 2 is automatically unlocked.

6 and 7 have been described as the moving object detection determination method after a predetermined time has elapsed since the door 10 that was opened has been closed, but this control method allows a predetermined time to elapse after the closed state of the door 10 is detected. Instead of waiting, when detection and non-detection of the detection signal by the moving body sensor 4 are repeated a predetermined number of times, it can be determined that there is a moving body and can be applied to the load receiving device 1 that automatically unlocks the electric lock 2.
That is, the flowchart of FIG. 6 described above describes an example of operation after a predetermined time (T) has elapsed, but immediately after the door sensor 3 detects that the door 10 has been closed after a predetermined operation. In addition, by performing the operation shown in FIG. 6, it is possible to distinguish the stored object from the high temperature from the moving object, and it becomes possible to detect the appropriate moving object.
Similarly, the time chart of FIG. 7 can be viewed as a time chart of the operation state of the moving body sensor 4 immediately after the door sensor 3 detects that the door 10 is closed after a predetermined operation.

In addition, although the goods receiving apparatus 1 described about the example used for the collective housing delivery box A here, it is not limited to this, It can apply also to the detached house receiving apparatus. In addition, the present invention can also be applied to the cargo receiving device 1 provided in an office, leisure facility, station, or the like.
Further, here, the load receiving device 1 having the door 10 provided only on one side has been described, but the present invention is not limited to this, and the present invention can be applied to a double-sided door type load receiving device 1 having a delivery side door and a receiving side door. In this case, door sensors 3 are provided on both the delivery door and the receiving door, and the above-described control is performed by detecting the open / closed state of both doors 10.
Further, here, an example is described in which the electric lock 2 is locked when the door 10 is closed after a predetermined operation. However, the present invention can also be applied to an apparatus that is automatically locked when the door 10 is closed. . The moving object detection determination method is not limited to the above-described example.
