And have. This control device 4 is equipped with a microcomputer base (not shown) and has signal input / output processing and communication processing functions with each device. Peripheral devices such as the car-side control device 5 and the landing-side control device 8 To control. Further, a car-side control device 5 and a door motor 6 for controlling the opening and closing of the door are provided on the car. The car-side control device 5 and the control panel 4 communicate with each other by a tail cord 7 to exchange signals. . At the landing, there is a landing call button 85 in the landing side control device 8, and the car 1 can be called to the floor.

  The person who uses the elevator carries the RF tag 9 for personal authentication in advance. The information in the RF tag 9 is written with at least a personal authentication code. The RF tag 9 for personal authentication is not limited to the RF tag, and may be an authentication medium by any other authentication method, and records information for elevator use log and elevator control such as a use permission floor and a weight [Kg]. But it ’s okay.

  On a predetermined floor of the elevator, an RFID information read / write device is installed as a landing customer authentication device 10 that reads information from an RF tag 9 as an authentication medium that is always carried by a waiting customer. The read information is transmitted to the elevator control device 4 via the tail cord 7. This transmission information is collated with data stored in the personal authentication information storage database 11 of the elevator user recorded in advance to perform personal authentication as to whether or not the user is permitted to use.

  Similarly, an image analysis device 12 capable of analyzing the number of waiting passengers by a combination of an imaging camera and an image processing device is installed on the same floor as a landing waiting customer number detection device. The analysis result is also transmitted to the elevator control device 4 in the same manner. The

  Based on these information, the elevator control device 4 determines that there is a person who is not permitted to use the elevator, that is, a suspicious person 13 when the number of waiting passengers by image analysis is larger than the number of persons carrying the RF tag 9. Suppress the use of elevators.

  In order to suppress the use of the elevator, service responses to the floor are prohibited when the car is running. Further, when the vehicle is decelerated and the door is closed, the vehicle is evacuated to another floor while the door is closed to prevent the passenger in the car and the suspicious person 13 from entering the car.

  The presence of the suspicious person 13 is notified to the landing waiting passengers through an announcement or display to the landing (not shown) to call attention. Moreover, it is good also as a means to notify by the method which is not noticed by the suspicious person 13 by blinking the landing lamp etc. which only the said elevator user can judge.

  In addition, an encryption device 14 for canceling suspicious person detection using a numeric keypad is installed at the hall as a consideration when an RF tag non-carrying person such as a friend who is accompanied by a legitimate user rides.

  In addition, when a load detection device 15 installed under the landing floor is used as the landing waiting number detection device instead of the image analysis device 12, as shown in FIG. In addition, the stand-by position is indicated by a frame 16 or the like at the landing, and the elevator user is informed as an elevator usage rule. The authorized user can determine that the person waiting outside the waiting frame 16 is the suspicious person 13 other than the elevator use authorized person, and can avoid riding in the car.

  FIG. 2 is a schematic control functional block diagram of an elevator to which an elevator security system according to an embodiment of the present invention is applied.

  The control block contents in this embodiment are provided with an elevator operation control means 41 for controlling the operation of the elevator in the elevator control device 4, and this control device 41 is mainly composed of an MPU, and includes at least a RAM area and a ROM. A storage unit (not shown) composed of areas is provided. This MPU controls the drive motor 3 of FIG. 1 to drive the car up and down according to the registration state of the hall call button 8 and a car call button (not shown).

  Further, as means for determining whether the waiting passenger is a person who can use the elevator, according to control for calculating the number of waiting passengers from information from the RFID device 10 installed at the landing, and other additions of users, etc. There is an RFID data control means 42 having control for rewriting the RF tag information to be carried and storing the information in a personal authentication database.

  Further, as the suspicious person detecting means, there is a suspicious person detecting / determining means 43 for comparing and determining the number of persons carrying the RF tag with respect to the image analysis number information of the hall installation, and determining the presence of the person who is not permitted to use the elevator. .

  Furthermore, if the suspicious person detection means determines that there is a suspicious person, determine what to do when there is a suspicious person such as prohibition of stoppage to the elevator, evacuation operation to another floor, or external alarm notification. In addition, there is a suspicious person response control means 44 for giving a control command to the elevator operation control means 41 for comprehensively operating the elevator.

  The car-side control device 5 drives the door motor 6 in response to a door opening / closing command from the elevator control device 4 to open / close the door, a destination button 51, a door opening / closing button, illumination, a signal light, and broadcasting. There are various signal control means 52 on the car side for performing input / output of the above and the like and guide means 53 in the car.

  If the elevator control device 4 determines that there is a suspicious person 13, first, the car-side control device 5 is prohibited from any control in the car such as door opening / closing control and car call button registration. Next, on the floor other than the suspicious person detection floor, the floor on which the suspicious person 13 is present is displayed and broadcasted. At the same time, the stand-by state is maintained with all the doors open, and thereafter, the service is suspended for a certain time.

  The hall-side control device 8 normally inputs / outputs hall buttons, hall guidance displays, signal lights, broadcasts, and the like by the hall signal control means 81. At the landing, an RFID information reading / writing device 82 (symbol 10 in FIG. 1) is installed on at least one floor, and the waiting information read by the device is transmitted to the elevator control device 4. In addition to the above, it is in charge of writing information in the RF tag 9 carried in advance by a user who is permitted to use the elevator.

  Further, on the installation floor of the RFID information reading / writing device 82, a waiting image analysis unit 83 for determining the number of waiting customers based on information obtained from the image analysis device 12 for determining the number of waiting customers by image analysis. is there.

  In addition to the suspicious person detection according to the present invention, the landing side control device 8 is used for canceling the suspicious person detection that switches the suspicious person detection at the landing to the released state in accordance with a numeric keypad operation or the like provided at the landing. The cipher input means 84 is arranged.

  FIG. 3 is a flowchart showing a processing procedure of the security system according to the embodiment of the present invention.

  Here, with reference to FIG. 3, the operation example of the security system in a present Example is demonstrated. First, in step 301, it is determined whether there is any suspicious person detection cancellation operation installed at the hall. This detection cancellation operation is performed so that the suspicious person detection is not performed by the cryptographic input device 14 for canceling the detection of suspicious person installed at the hall according to the establishment of the cryptographic operation combination condition of the numeric keypad input number as one embodiment of the present invention. is there. In other words, it is normally possible to use the elevator together with a friend who does not have the RF tag 9 that is carried by the elevator permitter at the judgment of the elevator permitter. The release operation method may be permitted when a security release condition such as a biometric authentication device or a magnetic IC card reader is established. Any one of the cancellation condition establishment signals is transmitted to the elevator control device 4 to cancel the suspicious person detection at the landing.

  In step 302, information on the RF tag 9 in the response floor is read. The read information is transmitted to the elevator control device 4, and the RFID registration information recorded in advance and the read information are collated to determine whether or not the elevator is permitted to ride, and the number of persons allowed to enter the elevator is estimated. .

  In step 303, the number of waiting customers is calculated by the combination of the imaging camera and the image processing device at the floor. In step 304, when there are more image analysis persons than the elevator boarding permission persons calculated | required in step 302 and step 303, it is judged that the suspicious person 13 exists in the boarding of an applicable floor. Further, as described above, when the load detection device 15 is used instead of the hall image analysis, the total weight [Kg] of the hall waiting customer and the weight of each individual written in the RF tag 9 that is carried by the passenger in advance. When the total weight of [Kg] is compared and the weight of the waiting passenger is higher, the presence of a person who is not permitted to use the elevator can be detected. At this time, the measured individual weight [Kg] data is recorded from the RFID device 10 to the personal information storage database 11 via the elevator control device 4.

  If it is determined that there is a suspicious person, the current position of the car is determined in step 305. If the car is located at a position other than the response floor, the process jumps to step 307 to execute another floor retreat operation for driving to another floor other than the response floor and opening the door. That is, when the elevator is located on a floor other than the response floor, the elevator is stopped on a floor other than the floor where the suspicious person is present to avoid encountering the suspicious person.

  On the other hand, if the current position of the car is the response floor at step 305, the door open state at the response floor is determined at step 306. If the door is closed, in step 307, the evacuation operation is performed to another floor while maintaining the door closed. That is, when decelerating and stopping to a floor where a suspicious person is present, or when the vehicle is already stopped and is in a closed state, a retreat operation is performed to another floor while keeping the door closed. If the door is open on the floor where the suspicious person is present, in step 308, the door is kept fully open to avoid a sealed state due to the door being closed. At this time, the door closing button in the car is invalidated.

  Simultaneously with the detection of the suspicious person, in step 309, the fact that an abnormality has occurred is notified to the landing standby person, the passenger in the car, the building use floor, the manager and the security company. In order to avoid a suspicious person's uplifting behavior, the suspicious person notices the abnormal notice to the waiting person on the same floor as the suspicious person. There is no guidance. The service control or prohibition of the elevator control by the suspicious person detection is maintained for 3 minutes from the detection. If it is approximately 3 minutes, it is assumed that the evacuation action from the suspicious person is also completed, and after the time measurement in step 310, the processing of the security system is terminated and the elevator service is restarted. The three minutes may be continued until a cancel operation by an administrator or the like is performed in accordance with the customer request of the elevator.
