It is drawing substitute photograph which showed the block diagram of the Example of the monitoring apparatus which concerns on embodiment of this invention. FIG. 2 is a drawing-substituting photograph showing a basic flowchart of functions of the joint master in the embodiment of FIG. 1. 3 is a drawing substitute photograph showing a detailed flowchart of step S22 in FIG. 3 is a drawing substitute photograph showing a detailed flowchart of step S24 in FIG. 3 is a drawing substitute photograph showing a detailed flowchart of step S34 in FIG. 3 is a drawing substitute photograph showing a detailed flowchart of step S38 in FIG. FIG. 3 is a drawing-substituting photograph showing a detailed flowchart of step S36 in FIG.

FIG. 1 is a block diagram showing an example of a monitoring apparatus according to an embodiment of the present invention. The embodiment is configured as an intercom system in an apartment house, and a resident or a visitor who arrives at the apartment house from the street 2 first enters the common entrance hall 6 as indicated by the route 4. At this time, the human sensor 8 detects a visitor and transmits a detection signal to the joint master unit 12 in the management room 10. In response to the sensing signal, the joint master unit 12 sends instructions to the joint slave unit 14 and the joint recording unit 16 to start recording the images of the hall camera 18 in the joint recording unit 16. The hall camera 18 can take an image of any number of visitors in the common entrance hall 6. For this purpose, a plurality of hall cameras 18 are provided in the common entrance hall as necessary.

Next, a resident or a visitor operates the operation unit 20 of the coordinating device 14, but in the case of a resident, the operation unit 20 is operated by inserting an unlocking card, inputting a password, or biometric authentication. When it can be confirmed that the operation is a resident's operation, the joint master unit 12 does not operate the slave unit camera 22 but immediately sends an instruction to the joint slave unit 14 to unlock the electronic lock 24 and open the common entrance hall. 6 is allowed to pass into the interior of the vehicle 6 and the operation of the elevator 26 is permitted. As a result, the resident can get into the elevator 26 and designate the destination floor as shown by the route 28.

On the other hand, in the case of a visitor, a room number is input to the operation unit 20 to call a visitor by the interphone function. In this case, the joint master unit 12 sends an instruction to the handset camera 22 and the joint recording unit 16 to start recording the image of the handset camera 22 in the joint recording unit 16. Since the handset camera 22 also serves as an interphone camera, the face of the visitor who operates the operation unit 20 can be imaged.

At the same time, the joint master unit 12 transmits the ringing tone signal and the image of the slave unit camera 22 to each of the base units 32 of the room number (for example, the room number “814” of the A house 30) input to the operation unit 20. introduce. The image of the slave camera 22 is displayed on the master monitor 34, and the voice of the visitor by the microphone 36 of the joint slave 14 is heard by each door guard 32 and the voice of the visitor is heard by the speaker 38 of the joint slave 14. You can talk to visitors by telling them. If it can be confirmed that the visitor is safe by such conversation and the image on the master monitor 34, the resident of the A family 30 operates each door master 32 and transmits an unlock signal. As a result, the joint master unit 12 sends an instruction to the joint slave unit 14 to unlock the electronic lock 24 to allow passage inside the joint entrance hall 6 and allow operation of the operation unit 27 in the elevator 26. To do. As a result, the visitor can open and close the door of the elevator 26 and designate the destination floor as shown by the route 28.

In addition, the resident of the A family 30 performs different operations depending on whether or not he / she is an acquaintance when transmitting the unlocking signal. For this purpose, each door-to-door unit 32 is provided with two types of unlocking signal transmission buttons for acquaintances and courier companies, or an auxiliary button is provided. Configured to be able to press a button. In any case, in the case of an acquaintance, an “acquaintance flag” is attached to the unlocking signal and transmitted to the joint master unit 12. When the acquaintance flag is not attached, the joint master unit 12 responds to the unlocking signal and makes a recording warning announcement such as “Your image has been recorded” by the speaker 38. This may be a courier pretending to attempt a criminal offense to the A family 30 or, for the time being, let the A family 30 cleverly unlock the word and first enter the common entrance hall and do not know this It is intended to be a deterrent effect on those attempting to commit crimes against residents in the common space of a house or apartment complex, and should be concise and intimidating. In addition, for the bona fide and first-time visitors who understand security without any suspicion, it is assumed that such warnings will be received during work.

On the other hand, when the joint master unit 12 has an acquaintance flag attached to the unlocking signal, “This condominium is recording all the interphone images of all customers in order to ensure security. Thank you very much for your understanding and cooperation. ” This relieves discomfort when it is later found that the recording is made without permission, and considers the expression of the notice. The presence / absence of acquaintance flags is added to the recording, and in the event that an incident is to be searched for recording for evidence investigation, it is also useful for extracting acquaintances and other visitors by purpose of the investigation. And contribute to the efficiency of the examination of evidence. Moreover, since the image accompanied by the acquaintance flag recorded in the joint recording unit 16 is privacy information for both the resident and the visitor, it can be reproduced without permission unless a predetermined procedure is agreed upon by the parties concerned of the A family 30. It is considered not to be able to.

As described above, the child camera 22 is not recorded in the case of a resident, but is recorded only for the visitor. The hall camera 18 is a resident of a housing complex or a visitor. Regardless, imaging is started in response to the human sensor 8, and all the images are recorded in the joint recording unit 16. This is to cope with a case where, when the electronic lock 24 is unlocked, a malicious person who did not perform the unlocking operation following the bona fide visitor subsequently enters. For this reason, the hall camera 18 detects the number of persons trying to enter the common entrance hall 6, and when one of them unlocks the electronic lock and a plurality of persons enter the inside, the fact is displayed in the image. Add and record. This supplementary information is useful for extracting such visitors in the event that an incident searches for recordings for evidence investigation, and contributes to the efficiency of evidence examination. The entrance of multiple people can be considered in various cases, such as when a malicious person slides after a resident, or when a group of bona fide visitors enters, and it is difficult to distinguish between them. Therefore, it is configured to leave records and supplementary notes for all cases. In addition, the detection of whether or not there are a plurality of people uses the output of the human sensation 8 in addition to the image analysis of the hall camera 18.

An elevator camera 40 is installed in the elevator 26, and any number of people in the elevator 26 can be imaged in the same manner as the hall camera 18. For this purpose, a plurality of elevator cameras 40 are provided in the elevator 26 as necessary. Further, the elevator camera 26 is configured to record images of all elevator users in the joint recording unit 16 just in case, just like the hall camera 18. When the elevator 26 is started from the common entrance hall 6, when a plurality of people are detected or a visitor having no acquaintance flag is detected by the speaker 42, “In this apartment, all elevator images are displayed. A warning announcement such as “I am recording.” This has the meaning of a rewarning for a malicious visitor without an acquaintance flag or a warning for a malicious person who has slipped through the electronic lock 24 without performing the unlocking operation himself. In addition, it is assumed that a good-willed user who does not feel suspicious will receive such a warning at the first visit or at the time of unspecified multiple passengers, and will be understood. In addition, such announcements are made because it is troublesome for the elevator 26 not starting from the common entrance hall 6 or a resident or a visitor with an acquaintance flag who rides on the elevator 26 alone from the common entrance hall 6. Absent.

A person who gets off the elevator 26 on the destination floor as shown by the regular route 44 reaches the target A house 30 through the internal passage 48 on the floor as shown by the regular route 46 and operates each door unit 48. As a result, the handset camera 50 captures the face of the visitor and this is projected on the base monitor 34. Therefore, if the door of the house A 30 is unlocked after a slight conversation by the interphone function with a normal image, the visitor can follow the route 52. It will be invited to A family 30 as follows. Note that an image captured by the slave camera 50 can be recorded by operating each of the door-to-door devices 32 as necessary.

The embodiment is an intercom system in an apartment house in which a large number of households live. However, in order to show the relationship with the common entrance hall 6, only the B house 54 is shown in FIG. The B house 54 has the same configuration as that of the A house 30, and has each of the door parent devices 58 connected to the joint parent device 12 and having a parent device monitor 56. Each door unit 62 is connected to each door unit 58 and has a child camera 60. Since the relationship between the common parent machine 10 and the common child machine 14 in the B house 54 is the same as that in the A house 30, further explanation will be omitted. Cooperate with hall 6, common management room 10 and common elevator 26. Moreover, the function which mutually prevents the malicious thing invited to the housing complex by the unlocking operation from each house planning the crime against the own house or another house is as having demonstrated A family 30.

FIG. 2 is a basic flowchart showing functions of the joint master unit 12 in the embodiment of FIG. The joint master is basically composed of a computer, and the flowchart of FIG. 2 shows the operation of this computer. The flow starts with the installation of the system. First, in step S2, it is checked whether or not the human sensor 8 detects the presence of a person in the common entrance hall 6. If there is no detection, step S2 is repeated to wait.

When the human sensor 8 senses the presence of a person in the common entrance hall 6 in step S2, the process proceeds to step S4, instructs the start of recording of the image of the hall camera 18 and proceeds to step S6. In step S6, thereafter, it is checked whether or not the human sensor 8 does not detect a person in the common entrance hall 6 for a predetermined time or more. When the corresponding state is reached, the process proceeds to step S8, the recording of the image of the hall camera 18 is stopped, the process returns to step S2, and the next sensing is awaited. On the other hand, if it is determined in step S6 that the state in which no person is detected does not correspond to a state that continues for a predetermined time or longer, the process proceeds to step 10 to check whether the operation unit 20 of the joint slave unit 14 has been operated. If there is no operation, the process returns to step S6, and thereafter, steps S6 and S10 are repeated until the predetermined time elapses to wait for the operation of the cooperative slave unit 14.

When the operation of the cooperative slave unit 14 is detected in step S10, the process proceeds to step S12, and it is checked whether the operation is a number operation for calling the visited room number by the interphone function. If it is a number operation, the process proceeds to step S14 to instruct start or continuation of the recording of the operator's face based on the image of the slave camera 22, and in step S16, the image of the slave camera 22 is displayed to each callee. The information is transmitted and notified that it is called, and the process proceeds to step S18.

In step S18, it is checked whether or not an unlocking signal is returned from the corresponding call destination. If there is no reply, the process proceeds to step S20 to check whether or not a predetermined time has elapsed from the call notification. If the predetermined time has not yet elapsed, the process returns to step S14, and thereafter, steps S14 to S20 are repeated unless a unlocking signal is returned or the predetermined time has not elapsed. On the other hand, if there is a reply to the unlocking signal in step S18, the process proceeds to step S22, number operation processing relating to recording and announcement at the time of number processing is performed, and the process proceeds to step S24. Details of the number manipulation process in step S22 will be described later.

On the other hand, if it is not a number operation in step S12, it means that the operation is a resident return home operation by unlocking card, password input, biometric authentication, etc., and the process proceeds to step S26. In step S26, a notification that the resident has returned home is sent to each of the door-to-door devices 32. This is a notice to the family to return home. After that, it is possible to assume that the operation of each child device 48 within a few minutes is that of the family who has returned home, and when there is no operation of each child device 48 within the expected time. It is also possible to quickly detect any abnormality from the entrance to the common entrance to the arrival of A family 30. In the case of a single person, the notification signal in step S26 can be used to turn on the lighting of the A house 30 or the switch of the air conditioner. In addition, since it transfers to step S24 after notification of step S26, recording of the subunit | mobile_unit camera 22 image in the common entrance hall in step S14 is not performed.

In step S24, multi-person processing related to recording and announcement in the case of multi-person admission is performed. Details thereof will be described later. After these steps, the flow proceeds to step S28, and the unlocking of the electronic lock 24 in the common entrance hall 6 is instructed. Then, in step S30, an instruction to stop recording by the slave camera 22 is issued if the recording by the hall camera 18 in the common entrance hall 6 and the recording are performed. Further, in step S32, an instruction to permit the operation of the elevator is given. As a result, visitors to the common entrance hall 6 can open and close the elevator doors and specify the destination floor.

Next, in step S34, elevator processing relating to recording and announcement in the elevator is performed. Details thereof will be described later. In step S36, recording management processing relating to recording privacy management is performed, and the flow returns to step S2. When it is detected in step S20 that the predetermined time has passed without a reply to the unlocking signal, the process proceeds to step S38, where the answering process is performed, and the process returns to step S2. The absence recording process in step S38 notifies that recording has already started and prompts the addition of a voice message, the details of which will be described later.

FIG. 3 is a flowchart showing details of the number manipulation process in step S22 of FIG. When the flow starts, it is checked in step S42 whether an acquaintance flag is attached to the unlock signal. If it is not attached, the process proceeds to step S44, and a recording warning announcement instruction such as “Your image has been recorded” is given by the speaker 42 of the slave unit 14. Further, in step S46, an outsider warning signal is added to the recording, and the flow ends.

On the other hand, when it is detected in step S42 that the acquaintance flag is attached to the unlocking signal, the process proceeds to step S48, and “This condominium records all the interphone images of all customers in order to ensure security. I would like to thank you for your understanding and cooperation. ” Further, in step S50, the outsider reference information is added to the recording, and the flow ends. As described above, the difference between the announcement and the additional signal is useful for the announcement effect depending on the acquaintance and the subsequent recording search. Also, as described above, it is considered that the recording with the outsider reference signal added cannot be reproduced without permission. This will be further described later.

FIG. 4 is a flowchart showing details of the multi-person process in step S24 of FIG. When the flow starts, it is checked in step S52 whether a plurality of people are detected by image processing based on the image of the hall camera 18. If the image processing cannot be detected, the process proceeds to step S53 to check whether or not a plurality of persons are detected by the human sensor 8. When a plurality of persons are detected by the human sensor 8, the process proceeds to step S54. If a plurality of people are detected by the image processing based on the image of the hall camera 18 in step S52, the process proceeds directly to step S54. In this way, when a plurality of persons are detected by either the image processing or the human sensor and the process reaches step S54, a multi-person warning signal is added to the image.

Further, in step S56, it is checked whether or not a recording warning announcement has been instructed through step S44 of FIG. If it has not been instructed, the process proceeds to step S58, and it is checked whether or not a recording tolerance announcement has been instructed through step S48 of FIG. If this is also not instructed, the process proceeds to step S60, where a recording warning announcement is instructed by the speaker 42 of the cooperative slave unit 14, and the flow ends. If it is detected in step S58 that a recording tolerance announcement has been instructed, this is canceled in step S62, and the process proceeds to step S60 to replace with a recording warning announcement instruction.

As described above, even if a recording tolerance announcement by an acquaintance flag is instructed at the stage of number operation processing in step S22, if a plurality of people are detected in the subsequent processing of step S24, the announcement is warned from tolerance. Upgrade to This corresponds to a case where a suspicious person enters following the release by the acquaintance's number operation process. On the other hand, in step S56 in FIG. 4, if the recording warning announcement has already been instructed in the number operation processing stage in step S22 in FIG. 2, there is no need to add or change the announcement, and the flow is immediately terminated. Even if the human sensor does not detect a plurality of people in step S53, there is nothing to be done in the multi-person process, and the flow is immediately terminated.

FIG. 5 is a flowchart showing details of the elevator process in step S34 of FIG. When the flow starts, it is checked in step S72 whether the elevator has started. When the start is detected, the start or continuation of recording based on the image of the elevator camera 40 is instructed in step S74. Next, in step S76, it is checked whether the elevator 26 has started from the common entrance hall 6. This corresponds to checking whether or not the person on the elevator has passed through the common entrance hall 6. If it is a start from the common entrance hall, the process proceeds to step S77, and it is checked whether there is information indicating that a plurality of people are detected in the common entrance hall 6 by the image of the hall camera 18 or the human sensor 8.

If the multiple person detection information in the common entrance hall cannot be grasped in step S77, the process proceeds to step S78, and it is checked whether multiple persons can be detected by the unique image processing using the image of the elevator camera 44. If a plurality of persons are detected, the process proceeds to step S80, and a multi-person warning signal is added to the image of the elevator camera 44 and recorded. Further, when information indicating that a plurality of persons are detected in the common entrance hall can be grasped in step S77, the process proceeds to step S80, and a warning signal for a plurality of persons is added to the image of the elevator camera 44 and recorded. The warning signal added in step S80 is also for convenience of later retrieval. Further, in step S82, an instruction to make a recording warning announcement to the speaker of the elevator 26 is given, and the process proceeds to step S84.

On the other hand, when a plurality of persons cannot be detected even in the image processing based on the elevator camera image in step S78, the process proceeds to step S86, and information on whether or not the operation in the cooperative slave unit 14 is a number operation is checked. If it is a number operation, in step S88 information on whether or not an acquaintance flag is attached to the unlocking information is checked. If there is no accompanying operation, the process proceeds to a recording warning announcement in step S82. This is to inform non-acquainted visitors that the recordings at various places remain by repeating warnings in the elevator 26 in addition to the warnings in the common entrance hall 6, and informing the malicious party of crimes. Significant to discourage execution.

On the other hand, if the information to be checked in step S86 is not a number operation, the resident is on the elevator alone, and if the acquaintance flag can be grasped in step S88, the resident is on the elevator alone. Means that you are an acquaintance. Therefore, since the recording in the elevator is well understood, the announcement in the elevator is refrained and the process proceeds directly to step S84 in order to avoid annoyance. Further, when the start of the elevator is not detected in step S72, or when the elevator is not started from the common entrance hall 6 in step S76, the process immediately proceeds to step S84.

In step S84, it is checked whether the elevator has stopped for a predetermined time or more. If not, the process returns to step S72. Hereinafter, as long as there is no stop for a predetermined time or longer, Steps S72 to S84 are repeated to deal with the entry and exit of people on each floor and the situation change. On the other hand, when it is detected in step S84 that the elevator is stopped for a predetermined time or longer, the process proceeds to step S90, the recording based on the image of the elevator camera 40 is stopped, and the flow is ended.

FIG. 6 is a flowchart showing details of the absence recording process in step S38 of FIG. When the flow starts, an instruction is given to announce to the speaker 38 of the Kyodo handset 14 that the absence recording has already started in step S92. Further, in step S94, an announcement is made to cause the speaker 38 to announce a message recommending voice input such as a message or greeting to the visitor. Then, step S96 is repeated to wait for a state where there is no voice input for a predetermined time. If it is detected in step S96 that there is no voice input for a predetermined time, the process proceeds to step S98, where an instruction to stop recording based on the images of the hall camera 18 and the slave camera 22 in the common entrance hall 6 is given, and the process proceeds to step S100. To do. This is because it is presumed that the visitor who operated the Kyodo child 14 left.

In step S100, it is checked whether or not there is an audio input during the absence recording. If there is a voice input, the process proceeds to step S102, where the normal answering signal is added to the image, and the flow ends. On the other hand, if it is not detected in step S100 that there has been an audio input during the absence recording, the process proceeds to step S104, the warning absence recording signal is added to the image, and the flow ends. If you are informed that it has already been recorded and that it will be seen later by the visitor, take action to leave a greeting or message in a voice so that it will not be rude if you are a bona fide person Based on the assumption that is normal. In other words, leaving the story silently while knowing that it is being recorded is likely to be a malicious person who came to confirm whether or not he / she was away. The warning message recording signal in step S104 also serves as a search facility when recording and reproducing later.

FIG. 7 is a flowchart showing details of the recording management process in step S36 of FIG. When the flow starts, it is checked in step S112 whether a multi-person warning signal is added to the recording. If not, the process proceeds to step S114 to check whether an outsider warning signal is added to the recording. If not, the process proceeds to step S116, and it is checked whether a warning message recording signal is appended to the recording. If none of these applies, the process proceeds to step S118, and protection by the unauthorized reproduction preventing door-to-door password is applied, and the process proceeds to step S120. If none of the steps S112 to S116 correspond, it corresponds to an acquaintance's visit image or normal absence recording image, and since both are high privacy images, the image recorded in the joint recording unit 16 is reproduced without permission. This is to prevent this.

On the other hand, since all the images corresponding to any one of steps S112 to S116 have low privacy, the process directly proceeds to step S120. In other words, no password is required, and anyone can play it back as soon as necessary. Note that step S120 is a process of inserting a falsification preventing digital watermark for enhancing the evidence of the image, and the process ends by this process.

The implementation of the various features of the present invention described above is not limited to the above embodiments. For example, the embodiment of FIG. 1 is configured on the premise that there is only one elevator 26 and there is a single route from the common entrance hall 6 to the inside of the apartment house, so the flow of FIG. It is composed. That is, unless the elevator process in step S34 in FIG. 2 is completed, it is configured so that visitors cannot be detected in the common entrance hall 6 in the next step S2. This is because it is assumed that the elevator 26 cannot enter the apartment house unless it returns to the entrance hall 6 and waits.
