Description

Elevator control device {CONTROLLER FOR ELEVATOR}

The present invention relates to an elevator control apparatus for detecting tailgating of suspicious persons.

In recent years, crime has increased in elevators such as apartments and apartments. For this reason, many elevators anticipate the effect of crime suppression, and provide the surveillance camera in the cage | basket | car, or the recording apparatus which records the image of a surveillance camera further. On the other hand, in recent years, the number of apartments which restrict access of non-residents has been increased by installing high-security security facilities that require password authentication or identity verification by ID verification. have.

However, it is difficult to completely prevent entry of a suspicious person even in a mansion equipped with high security equipment as described above. For example, even if the above-mentioned security equipment is introduced into the apartment, the suspicious person can enter the building relatively easily by burying or the like. For this reason, even in the elevator of the said apartment, the possibility that the occupant and suspicious person ride together can fully be considered. In addition, the above burial means that a suspicious person who has not been authenticated enters the house with the occupant when the door is opened due to the identity of the occupant. Of course, this can happen even in elevators that restrict riding.

For this reason, conventionally, various proposals have also been made about buried in an elevator. For example, in the case of registering a landing door using a predetermined ID card according to the prior art, a voice guidance that cannot be carried out is repeatedly performed after the door is opened, and the door is closed immediately after confirmation of the boarding by the door sensor. It is proposed to prevent riding of suspicious persons (see Patent Document 1).

Patent Document 1: Japanese Patent Application Laid-Open No. 2006-27886

Although the patent document 1 performs various operation | movement which prevents burying, it does not actually detect burying. Therefore, even if burying occurs, it cannot be detected, and there is a concern that the operation of the elevator can be continued while the ID holder and the suspicious person ride in the car.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a control device for an elevator that can detect burial with a cheap structure and can perform an appropriate operation at the time of burial detection.

An elevator control apparatus according to the present invention includes an elevator car for elevating the inside of an elevator hoistway; An ID matching device that checks whether or not the person is registered in advance; A non-contact door sensor that detects the presence or absence of a user riding in a car and the number of people thereof optically or visually; Scale detection means for detecting a load of the user in the car based on the loaded weight of the car; The ID matching device detects the use of the elevator by the person, and by both the non-contact door sensor and the scale detecting means, a suspicious person who is not authenticated as the person by the ID matching device rides the car with the person. Buried detecting means for detecting the occurrence of buried in the case where it is detected; When the occurrence of the burial is detected by the burial detecting means, the burial control means is provided to release the burial and to perform a predetermined operation for informing the outside of the burial.

According to the present invention, it is possible to detect burrows with a cheap structure and to perform appropriate operations at the time of burial detection.

An ID control device for controlling the device 6. In addition, the said ID collation apparatus 6 is used when the said specific person uses an elevator, and is installed in the elevator platform and the cage | basket | car 1. FIG. 8 is a scale apparatus for detecting the load weight in the car 1. This scale apparatus 8 is provided in the edge part of the main rope (not shown) which suspends the cage | basket | car 1, for example. Moreover, 9 is the monitoring center which monitors an elevator installed in the building provided with an elevator, or a remote place.

10 is control means which manages the whole operation control of an elevator. This control means 10 is equipped with the travel control means 11, the scale detection means 12, the communication means 13, the bury detection means 14, and the bury control means 15, for example. Each means shown to 11-15 is comprised by software.

The driving control means 11 has a function of performing overall operation management of the elevator. For example, an operation command to the elevator hoisting machine (not shown) and an operation command to the door control means 4 are outputted from the travel control means 11. The scale detecting means 12 detects the car load based on the input information from the scale apparatus 8. That is, the scale detection means 12 detects the presence or absence of the user in the cage | basket | car 1, and the number of people based on the loading weight of the cage | basket | car 1 detected by the scale apparatus 8. The communication means 13 has a function for the control means 10 to communicate with external devices and the like. For example, the devices installed in the car 1 and the platform, the ID control device 7 and the monitoring center ( 9) and the like.

The buried detecting means 14 has a function of detecting buried generated in the elevator. The burying detection means 14 detects the occurrence of burying based on the matching result of the ID matching device 6, the detection result of the non-contact door sensor 5, and the detection result of the scale device 8. Then, when the occurrence of burial is detected by the burial detecting means 14, the burial control means 15 releases the burial, informs the occurrence of burial to the outside, or prevents criminal activity. A predetermined operation for the elevator is performed.

Next, operation | movement of the control apparatus of the elevator which has the said structure is demonstrated.

2 is a flowchart showing the operation of the elevator control device according to the first embodiment of the present invention. The control device of the elevator performs normal running on the running control means 11 until information for ID matching is input to the ID matching device 6. When predetermined information is input to the ID collation apparatus 6, ID collation is performed by the ID control apparatus 7, and identity verification of whether a collator is a predetermined person registered beforehand is performed.

When the use of the elevator by the specific person is detected by the ID matching device 6 (S101), the control means 10 next by the balance detecting means 12 and the non-contact door sensor 5, the ID matching device. It is determined whether or not the suspicious person who has not been authenticated by (6) boards the car 1 together with the above-mentioned specific person. That is, various operations are performed to determine whether burying has occurred. For example, it is determined by the scale detecting means 12 whether the riding of a plurality of people has been detected (S102), and whether the riding of a plurality of people has been detected by the non-contact door sensor 5 (S103), The number of people is compared. The buried detecting means 14 detects that the suspicious person carries the car together with the specifier when the plurality of passengers are detected by S102 and S103, that is, by the scale detecting means 12 and the non-contact sensor 5. When it is detected that the passenger rides on (1), the occurrence of burial is judged (S104), and the information on the effect is sent to the burial control means 15.

When the occurrence of the burial is detected in S104, the burying control means 15 notifies the monitoring center 9 to stop the car 1 on the nearest floor (S105, S106), and then completely opens the door. Various operations such as In addition, each operation below S105 is not limited to the above-mentioned operation, For example, various operation | movement, such as ringing an alarm buzzer, continuing the open state of a door, switching to each floor stop operation, etc. are considered.

3 is a figure for demonstrating the function of the non-contact door sensor in Embodiment 1 of this invention. Based on FIG. 3, the specific detection method in S103 of FIG. 2 is demonstrated. 3 shows the case where the multi-beam door sensor is adopted as the non-contact door sensor 5, and the vertical axis of (a) to (c) is the detection information of each light receiving element provided at the end of the car door 2. The horizontal axis represents the time until the door (elevator car door 2 and landing door) starts to open and closes after the car 1 is stopped.

FIG. 3 (a) shows detection information of each light receiving element when an adult passes through the doorway 3 alone, and FIG. 3 (b) shows detection information of each light receiving element when two adults pass through the doorway 3 in succession. It is shown. In this way, by detecting the detection information of each light receiving element of the multi-beam door sensor continuously for each light receiving element, the presence or absence of the person who has passed through the doorway 3 and the number of people based on the detection information to a certain degree of precision Judging by

3C shows detection information of each light-receiving element when the child passes through the doorway 3 alone. In this way, when a short person such as a child or a pet or an animal or the like has passed through the entrance 3, the light from the light emitting element disposed at the height near the head of an adult is not blocked. For this reason, as shown in FIG. 1, the predetermined optical axis arrange | positioned above the 1st optical axis and the 1st optical axis with the optical axis of a predetermined height from the bottom surface, and the predetermined optical axis arrange | positioned above the 2nd optical axis and the 2nd optical axis If it sets previously to a 3rd optical axis, passage of an eye etc. can also be detected based on the detection information of each light receiving element arrange | positioned on this 1st-3rd optical axis.

Fig. 4 is a flowchart showing another operation of the elevator control device according to the first embodiment of the present invention, and shows an operation when the passage of the eye or the like is also detected at the time of burying detection. In this case, the first to third optical axes are set in advance.

When the use of the specifier is detected by the ID collating apparatus 6, the control means 10 first determines whether or not the first optical axis is blocked (S201). When blocking of the first optical axis is detected in S201, it is determined whether the second optical axis or the third optical axis is blocked next (S202). Here, when blocking of the 2nd optical axis and the 3rd optical axis in S202 is not detected, it is judged that the child (pet) boarded as mentioned above (S203), and the driving control means 11 performs the door control means ( For 4), the operation command is output to set the door opening time slightly longer than the opening time during normal operation (S204). In addition, the operation | movement at the time of detecting the riding of a child etc. is not limited to the said operation | movement, For example, delaying the speed of a door, notifying to the monitoring center 9, guiding a voice in the cage | basket | car 1, etc. Various operations of are considered.

On the other hand, when the blocking of the second optical axis or the third optical axis is detected in S202, it is determined whether the second optical axis or the third optical axis is blocked again after a predetermined time has elapsed (S205). That is, the presence or absence of the next passenger is determined. And if blocking | disconnection of a 2nd optical axis and a 3rd optical axis is not detected in S205, it is determined that 1 adult boarded. On the other hand, when blocking of a 2nd optical axis or a 3rd optical axis is detected in S205, while the rider of several people is detected, the burying control means 15 makes various operations at the time of burying occurrence.

In addition, although the above is description of the case where the optical axis for detecting an eye etc. was set to the 1st thru | or 3rd, detection of an eye etc. is possible even using only a 1st and 2nd optical axis. In such a case, it is necessary to set the first optical axis at a height that is reliably blocked by the passage of the child, and the second optical axis at a height that is not blocked by the passage of the child but blocked by the passage of the adult. In addition, the ID matching device 6 or the scale detecting means 12 may be configured to detect the riding of the child, and the operation shown in FIG. 4 may be performed.

In addition, after extending the opening time of a door in S204, you may return to S201, and you may comprise so that occurrence of a burial may be detected. In such a case, the setting for extending the opening time of the door may be made effective until the occurrence of burial is detected by the burial detecting means 14.

According to Embodiment 1 of this invention, based on the detection result of the identification collation apparatus 6 and the detection result of the scale apparatus 8 and the non-contact door sensor 5, the buried in an elevator is ensured with a comparatively cheap structure. It becomes possible to detect. In addition, when burying is detected, an appropriate operation can be performed. Therefore, it becomes possible to greatly reduce crime using an elevator, and can provide a safe elevator with high security.

In the first embodiment, the case where the detection of the burial is always performed is described. However, the detection of the burial only at a specific time period, for example, at night, may be performed. Moreover, you may be comprised so that the operation | movement at the time of burying detection may be changed according to time zone, and the operation | movement, such as an alarm buzzer and the notification to the monitoring center 9, is performed only at night.
