A car control panel 7 is mounted on the car 1, and is composed of a communication device for transmitting / receiving signals to / from the elevator control panel 6, an I / O and a car position indicator 8, and a microcomputer for controlling opening / closing of the car door 9. To be done. In addition, the control panel 6 via the car control panel 7
Signal is input / output to / from the operation panel 10 in the car. Further, below the floor of the car, a load detector 12 for detecting the load of the passengers 11 in the car 1 is installed, and the signal thereof is transmitted to the control panel 6 via the car top control panel 7. The elevator control panel 6 has a CPU that functions as a central processing unit and an R
A microcomputer controller 13 including a storage device including an OM and a RAM is provided. The program in the present microcomputer control unit 13 is composed of a group of control function modules necessary for operating various elevators. Door 1 in basket 1
The security window 14 is provided in the.

On the other hand, at the hall, there is a hall call button 15 installed on each floor, and the call registration signal is the control panel 6.
It is configured to input / output to / from the microcomputer control unit 13 therein. Similarly, the car position is output to the car position indicator 16.
The inside information of the car 1 that has arrived at the landing can be confirmed on the security window 18 of the landing door 17.

In this embodiment, as will be described later,
The waiting passengers 19 at the landing have the right to decide whether to open the door of the elevator car 1. Security windows 18 to passengers 11 in the car
Is determined to be a suspicious person, and if the waiting passengers 19 at the hall recognize that it is safe, the door of the car 1 is opened by operating the hall button 15 again. If you feel a danger, landing button 1
If you do not operate 5, the car door will not open.

FIG. 2 is a functional block diagram of an operation control device for an elevator with a security window according to an embodiment of the present invention. The elevator operation basic control unit 20 is the content of the program stored in the ROM in the microcomputer control unit 13 in the elevator control panel 6 shown in FIG. With reference to the functional block diagram of FIG. 2, the flow of the functional units related to the embodiment of the present invention among the control units of the elevator will be described.

In addition to the processing according to the present embodiment, the elevator operation basic control unit 20 repeats the activation of the program for each task in a time-division manner at predetermined intervals. During these predetermined cycles, timer count processing, input / output processing, various operation method determination and operation control, speed control, abnormality processing, etc. are performed. Among these, the control function units related to the present embodiment are as follows. First, there is an in-car load detection processing unit 21 for checking the presence / absence of an in-car load by using a load detector 12 such as a load switch or a load sensor installed under an existing car.
Next, there is a car call response processing unit 22 for confirming a state where the elevator control device is responding to a car call by operating a call button or the like in the car operation panel 10 in the car 1.
Further, a door opening / closing processing unit 23 for confirming whether the door opening button in the operation panel 10 in the car 1 is operated to open / close the door.
There is. Further, there is a hall call response processing unit 24 that responds to the hall call registration and a car position calculation processing unit 25 that is necessary to stop at the destination floor.

Next, the security control unit 30 will be described. Under the processing of the basic control unit 20, it is possible to confirm that there is a load in the car without the car calling operation and the door opening / closing operation. The fact that this state continues for a predetermined time is considered to be waiting for the time when the suspicious individual responds to the hall call in the car 1. The suspicious person detection processing unit (means) 31 in the car operates under these conditions. Further, when the hall call is registered in the state where the suspicious person detection processing unit (means) 31 in the car determines that there is a suspicious person in the car, the hall call response processing unit 24 drives to the hall. Then, the car call button and the door opening button in the car are invalidated, and the "door opening processing unit (means) 32 by the operation of the landing call button" 32 that does not automatically open the door when the vehicle arrives at the hall operates. When the door opening processing unit (means) permits the door opening by the operation of the landing call button, the door opening / closing processing unit 23 performs the door opening operation.

FIG. 3 is a flowchart of a suspicious person detection process in a car of an operation control method and apparatus for an elevator with a security window according to an embodiment of the present invention. In step 301, it is determined whether or not the in-car button invalid flag is set. If the in-car button invalid flag is already set, the suspicious individual has already been detected, and the process this time ends. Step 302
Then, it is determined whether the car call button is operated. If the car call button is operated, the process proceeds to step 303 to perform a normal car call response process, and the suspicious person detection process is not necessary. If the car call button is not operated, the routine proceeds to step 304, where it is determined whether the door open button in the car is operated. If there is a door opening operation, suspicious individual detection processing is not necessary, and normal door opening / closing processing is executed in step 305. If neither of these operations is performed, it is determined in step 306 whether or not there is a car load. If there is no load in the car, there are no passengers and step 30
Moving to 7, the count of the timer counting the state where the button inside the basket is not operated is cleared, and in step 308,
If the suspicious individual detection flag in the car is set, clear it.

If it is determined in step 306 that there is a load, the duration is counted in step 309. Whether a suspicious person is waiting in the cage,
The determination is made under the condition that the car call button operation and the door open button operation are not performed and the load detection device 12 in the car is continuously operating for a predetermined time. Therefore, step 31
If the time limit of the in-car button non-detection timer expires at 0, the in-car suspicious individual detection flag is set at step 311. Further, if a car call operation or a door open button operation occurs or the output of the car load detection device 12 disappears at any time before the time limit of this timer expires, it can be determined that there is no suspicious person, so in step 307. Without operating the operation button in the car, clear the count value of the timer,
At step 308, the suspicious individual detection flag in the car is cleared.

As described above, when it is determined that there is a suspicious person in the car, the suspicious person detection flag is set and the security operation described below is started.

FIG. 4 is a flowchart of security operation processing according to an embodiment of the present invention. The determination result of FIG. 3 is configured to be held when a landing call for another floor is registered and the vehicle starts traveling to the destination floor. That is, even if a suspicious person in the car operates the car call button or the door open button, the door will not be opened when arriving at the hall call response floor.

First, in step 401, the presence or absence of a suspicious individual detection flag, which is the processing result of FIG. 3, is determined. If there is a suspicious person, the process proceeds to step 402 and it is checked whether there is a landing call button. When the landing call is registered, the car 1 starts traveling to the landing call response floor with the suspicious person on the car as usual. However, in step 403, a flag for disabling the in-car button is set to disable the car button operation and the door opening operation in the car. In step 404, it is determined whether the car carrying the suspicious person has arrived on the same floor as the floor call response floor or was originally stopped on the same floor, and it is determined that the car is at the door openable position. To do. In response to the fact that the car is stopped at the door openable position, it is determined in step 405 whether the hall call has been pressed again. If there is no re-operation of the landing call button, in step 406, the re-landing button non-operation detection timer starts counting. When the hall call button is operated again, this is the result of the waiting passenger on the hall side judging that the passenger (or the object) in the car is safe, and the door is opened / closed by the door opening / closing process in step 407. In step 408, the re-hall call operation detection timer counter is cleared.

On the other hand, if it is confirmed in step 405 that there is no re-operation of the landing call button, the door is not opened as it is, and in step 406, the re-landing button non-operation detection timer starts counting. To do. During this time, the passenger waiting at the hall can check the inside of the car through the crime prevention window, and if it is judged to be safe and operates the hall call button, step 405.
Can proceed to step 407 to open the door. If the waiting passenger is judged to be dangerous, the landing call button is not operated and the waiting passenger can evacuate.

The count value of the timer in step 409 is compared with the time limit value set in the ROM in advance, and it is determined whether or not the re-hall call button no-operation detection timer has expired. During this time, there is a suspicious person in the car, and the passengers on the landing side have enough time to evacuate from the place. Upon expiration of this time limit, the in-car button invalid flag is cleared in step 410. Therefore, a suspicious person in the car can get off at the landing side with the door open button. The suspicious person may be trapped and captured as it is.

In this embodiment, a multi-floor landing call 15, a car 1 of an elevator that operates between floors in response to a car call in the car 1, and a load detector for detecting passengers in the car 1. 12 and an elevator with a crime prevention window provided with windows 18 and 14 for crime prevention provided in the landing door 17 and the car door 9, the car call registration operation in the car 1 and the door opening operation in the car are not performed. When the load detector 12 detects the presence of the passenger 11 for a predetermined period of time or longer, the suspicious person detection means 31 in the car (the processing is shown in FIG. 3) and the suspicious person detection means 31 in the car are in the operating state. When the call 15 is registered, the car call registration and the door opening button in the car are invalidated to prevent automatic door opening when arriving at the floor call generation floor, and the hall call button (operation means) 15 is operated again. Open when opened Door-opening means 32 (process 4) is provided with a.

According to this embodiment, it is possible to economically reduce the chances of encountering a suspicious person, improve the safety of passengers in the elevator, and, for the suspicious person, a car call button or a door. Disabling the open button has the effect of making the person feel as if they were trapped and not performing the same action again.

In the above embodiment, since the load detector 12 is used as the passenger detecting means in the car 1, the system can be constructed more economically by using the existing load detector 12 for a normal elevator. However, it can be replaced with a known device such as an infrared sensor or a television camera arranged in the car 1. Further, although the elevator having the windows 14 and 18 for crime prevention that the waiting customer 19 can feel at ease has been described, the sensor information of the infrared sensor, the television camera, or the like can be displayed or notified to the waiting passenger 19 to substitute. . Further, the suspicious person detection means 31 is provided to assist the waiting passengers in making a decision.
8 and the above-mentioned sensor information alone, the suspicious person detection means 31 is not always necessary if, for example, the door is opened by an operation from the landing side only at night. This operation on the landing side is also economical by using the existing device if the landing call 15 is re-operated, but the security can be ensured even if other devices are used.
