Description

[Detailed Description of the Invention] The present invention relates to an elevator control device, and is particularly effective in emergencies such as when a crime occurs or an earthquake occurs.

Normally, with the exception of some examples such as those used for observation, elevators are completely closed rooms while they are in motion, and the interior of the elevator cannot be seen from the outside. Therefore, there is a risk that an emergency situation such as a crime may occur in a running elevator, and this is particularly likely to occur in an apartment building at night.

As a solution to this, conventional elevator doors have been equipped with glass windows so that the inside of the car can be seen from the outside, and elevators have been equipped with automatic switching panels that switch to stop operation at each floor at a preset time. thing,
Alternatively, there are cars that have an emergency button inside the car to ring an emergency bell or contact the outside, and are used for crime prevention at night. However, with the first method above, if a crime occurs, there is little chance of being rescued unless there are other passengers waiting in the hall, and with the second method, electricity is wasted except when a crime occurs, and operation efficiency is also reduced. Deteriorate. In the third method, since the emergency button is usually small like the other push buttons, it is often difficult to quickly determine which button is the emergency button and operate it when a crime occurs.

Furthermore, if the running state of the car becomes abnormal due to, for example, an earthquake or a failure of a control device, passengers inside the car become anxious and feel the urge to immediately stop the elevator and escape from the car. In such sudden situations, the passenger's ability to make decisions is impaired, and it is extremely difficult to calmly operate the emergency button or stop the elevator by operating the car call button for the nearest floor. be.

This invention was developed in view of the above points, and its purpose is to be able to quickly stop the car even if the person lacks the ability to make a calm judgment in the event of an emergency such as a crime occurring inside the car. The purpose of the present invention is to provide a device that allows the car to stop at the nearest floor and escape from the car. In other words, the present invention targets not only emergency buttons inside the car, but also all operation buttons such as door opening/closing buttons and car call buttons. When operated at the same time, it is determined that an emergency situation has occurred and the elevators are stopped at the nearest floor, allowing passengers to quickly escape from the car.

An embodiment of the present invention will be described in detail below with reference to the drawings. Note that for convenience of explanation, a case of a building with eight floors will be taken as an example.

Figure 1 shows the operation panel inside the elevator car, where COP is the car operation panel, 1C to 8C are the car call buttons for the 1st to 8th floors, respectively, DO is the door open button, DC is the door close button, and EM is an emergency button.

FIG. 2 is a circuit diagram showing an example of an emergency control device according to the present invention, and 10 is an emergency control device that detects that a predetermined number or more of the operation buttons in the car are operated simultaneously or within a predetermined time and emits an output signal 10a. The time detection device 20 is a known nearest floor stopping device that stops the car at the nearest floor using an output signal 10a. 1Ca
~8Ca (partially omitted) is the output signal of car call buttons 1C to 8C that output when operated, respectively.
Similarly, DOa, DCa, and EMa are also door opening buttons DO and
Door close button DC, emergency button EM output signals, CL is the basic clock signal, AN1 to AN11 (partially omitted) are
AND gate, BE1 to BE11 (partially omitted) are bistable multivibrators, 11 is basic clock signal
CL is counted, and when a predetermined number is reached, the bistable multivibrators BE1 to BE11, a counter 12, and a frequency divider that generates a preset signal P are counted. 12 counts the number of input signals from the bistable multivibrators BE1 to BE11. A counter 12a is its output signal, 13 is a counter that compares the output signal 12a corresponding to the value counted by the counter 12 with a predetermined reference value signal R, and when the output signal 12a exceeds the reference value signal R, outputs the output signal 10a. It is a comparator that emits .

In the above configuration, if an emergency such as a crime occurs in the car while the elevator is running, a passenger immediately presses each button provided on the car operation panel COP with his or her palm, and presses the car call buttons 4C and 8C. It is assumed that the door close button DC has been operated. Figure 3 is a diagram showing the timing chart in this case, and shows AN4a, AN4a,
8a and AN10a are AND gates AN4,
Similarly, the output signals of AN8 and AN10 are changed to BE4a,
BE8a and BE10a indicate output signals of bistable multivibrators BE4, BE8, and BE10, respectively. Times _t1 and _t2 indicate the timing at which the preset signal P of the frequency divider 11 is generated, and the preset is performed every time the number of pulses of the basic clock signal CL reaches a predetermined number. Car call button 4C, 8
C and door close button DC are pressed, and the output signal 4Ca,
Assuming that 8Ca and DCa are in the state shown in Figure 3,
The relationship between each of these output signals and the basic clock signal CL is
AND is AND gate AN4, AN8, AN1 respectively
0 and their output signals AN4a, AN8
a, AN10a is as shown in FIG. As a result, among the bistable multivibrators BE1 to BE11, BE4, BE8, and BE10 output the output signal AN4a,
Simultaneously with the input of AN8a and AN10a, output signals BE4a, BE8a, and BE10a are generated, respectively. Counter 12 is bistable multivibrator BE1~
Count the number of output signals from BE11 (3 in this case) and send the counting result to output signal 12a
Output as . Assuming that the reference value signal R is now 2, this and the above output signal 12a are
3, and in this case, the output signal 12a is larger, so the output signal 10a is issued, and the car is immediately decelerated to a stop at the nearest floor by the well-known nearest floor stopping device, and the passengers in the car are in danger. can escape. Meanwhile, at time t ₂ , counter 1
2 and bistable multivibrators BE1 to BE11
Since all are preset by the preset signal P, the same operation can be repeated.

Note that the present invention is not limited to the above embodiment, and the number of pulses of the basic clock signal until the reference value signal R is set or preset, that is, the times t ₁ and t ₂
It goes without saying that the setting of the interval between the two and the like is arbitrary.

In addition, although the above example shows an example in which only the car call button, door open/close button, and emergency button are provided inside the car, there are also buttons provided inside the car for operations related to elevator operation control. It can be anything.

In addition, the nearest floor is not affected by the presence or absence of a hall call for the floor, the presence or absence of a car call to the relevant floor, and whether the car call is canceled when the car is stopped at the nearest floor.

As described above, according to the present invention, by operating not only the emergency button or the car call button but any operation button inside the car in a predetermined number of times within a predetermined time, the car can be stopped at the nearest floor. Therefore, in the event of an emergency within the car due to a crime, earthquake, or other reason, the elevator can be easily and reliably stopped at the nearest floor and evacuated even if the passenger lacks the ability to make a calm judgment. passenger safety,
It can have a great effect on crime prevention, etc. Furthermore, when the vehicle stops on the nearest floor, an emergency bell will be sounded.
By combining it with a crime prevention device such as the one described above, such as communication with the outside, an even greater effect can be achieved.
