Description

[Detailed description of the invention]

The present invention relates to a control device for an elevator shared by physically disabled people and general passengers. Conventionally, in elevators shared by physically disabled people who use wheelchairs and general passengers, there are hall call buttons and in-car destination buttons exclusively for physically disabled people, in addition to hall call buttons and in-car destination buttons for general passengers. During the registration of the hall call button or in-car destination button for the physically disabled, the hall call button for general passengers is blocked from responding, and the hall call for the physically handicapped is given priority over others, causing the car to stop responding. It was for convenience. However, because hall calls for physically disabled people prevent hall calls for all general passengers,
The drawback was that many ordinary passengers had to wait for a long time. The present invention has been made in order to eliminate the above-mentioned drawbacks, and aims to provide an elevator control device that takes into consideration the waiting time of general passengers so that it does not exceed a set value while ensuring the convenience of physically disabled people. . The feature of the invention of this application is that during the registration of the hall call button for physically disabled persons or the in-car destination button, responses are blocked for general passenger hall calls for which the registration elapsed time does not exceed the set value, and the registration set time is set. A device will be installed to respond to hall calls for general passengers that exceed the limit, as well as calls from hall call buttons and in-car destination buttons for people with disabilities, so that calls for people with disabilities are given priority while general passengers are forced to wait for long periods of time. The aim is to alleviate the irritation caused by DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings regarding a fourth floor elevator.

Ru. Figure 5 shows the call relay of the call detection circuit for people with physical disabilities.
This is a diagram in which the b contact SHC (b2) of the SHC is inserted into the power supply circuit of the hall call direction selection circuit for general passengers.By energizing this call detection relay SHC for the disabled, direction selection by hall calls for general passengers is no longer possible. The operation of the elevator control device according to the embodiment configured as described above will be explained below. First, in Fig. 1, when the general passenger hall call registration button P2U in the upward direction to the second floor is pressed, (+)
The circuit is configured as follows: power line PC → general passenger hall call registration button P2U → short circuit prevention resistor 2UR → hall call registration relay 2U → (-) power line N.
Hall call registration relay 2U is energized and self-maintained by a contact 2U (a1) of this relay 2U. At the same time (+) power line PC → general passenger hall call registration relay contact 2U (a1) → short circuit prevention resistance 2UR
→The (+) power line is also connected to the fixed segment 2UN of the floor selector through the fixed segment 2UN circuit.
PC voltage continues to be applied. If the hall call button or in-car destination button for the physically disabled is not pressed and the elevator is ascending toward the second floor, the b contact SHC (b) of the call detection relay SHC for the disabled closes. Therefore, the a contact U (a1) of the upward direction detection relay U is also closed. Further, the deceleration command relay SLD in the deceleration command circuit is energized at the same time as the elevator starts running, and is demagnetized by the deceleration command, and its contacts SLD (b1) and SLD (b2) are open. In this contact state, when the distance between the elevator and the second floor reaches the deceleration distance, the movable segment F1 comes into contact with the fixed segment 2UN, and at that point, the fixed segment 2UN → movable segment F1 → contact of the upward direction detection relay U (a1) → Contact point of call detection relay for disabled persons SHC (b) Hall call detection relay HSL
→(-) A circuit for the power line N is formed and the Hall call detection relay HSL is energized. this relay
Due to the excitation of the HSL, an elevator deceleration command circuit (not shown) is activated to decelerate the elevator.
Eventually, it was brought to a halt on the second floor. In addition, the deceleration command relay is activated by energizing the hall call detection relay HSL.
Since SLD is demagnetized, contact HSL (a) and SLD
(b2) are both closed and hall call registration relay 2U
The (+) power supply side of is momentarily connected to the (-) power supply line N. Therefore, the hall call registration relay 2u is demagnetized and its self-holding is released, and the hall call is canceled. On the other hand, if the hall call registration button 2Pu for general passengers in the ascending direction to the second floor is pressed and the hall call button exclusively for the physically disabled is pressed while the elevator is ascending to the second floor, the detection relay
SHC is energized, and this relay's b contact SHC
Since (b) is open, even if the movable segment F1 contacts the fixed segment 2UN, the Hall call detection relay HSL will not be energized and no deceleration command will be given. Therefore, the upward hall call made on the second floor continues as is. On the other hand, when the handicapped person call detection relay SHC is energized, the current to the general passenger hall call direction selection circuit A shown in Fig. 5 is cut off by the contact SHC (b2), and the direction selection by the general passenger hall call is also disabled. become unable. From the above, it is clear that when a hall call for a physically handicapped person occurs, there is no need to respond to a hall call for general passengers. Next, when the general passenger hall call registration button P2U in the upward direction to the second floor is pressed, the a contact 2U (a2) of the general passenger hall call registration relay, which self-holds, is connected to the long-wait detection relay 2UX, It is connected in series with the long-wait detection timer 2UT between the power supplies PC and N, and at the same time as the contact 2u (a2) closes, the voltage of the (+) power supply line PC passes through the coil of the long-wait detection relay 2UX to the long-wait detection timer. Applied to 2UT. In this state, the long wait detection relay 2UX is not energized, but the rated voltage is applied to both ends of the long wait detection timer 2UT, and when the set time of this timer elapses, a short circuit occurs between both ends, and the long wait detection relay 2UX is also excited. By energizing this long-wait detection relay 2UX, the third
Contact point 2UX (a1) in the diagram closes and fixed segment 2
The voltage of the (+) power line PC is applied to UL.
If the elevator rises toward the second floor in this state, the movable brush F3 and the fixed segment 2UL come into contact, and furthermore, the contact U of the upward direction detection relay U
(a2) is also closed, so (+) power line PC → long wait detection relay contact 2UX (a1) → fixed segment 2UL → movable brush F3 → upward direction detection relay contact U (a2) → long wait detection relay A circuit of HLD→(-) power line N is formed, and the long wait detection relay HLD is energized. This long-wait detection relay
The HLD is also designed to output a deceleration command, and as soon as this relay is energized, the elevator starts decelerating and comes to rest on the second floor. That is,
If the registration elapsed time of the hall call for general passengers exceeds the set time of the long-wait detection timer and the direction of the hall call for general passengers matches the direction of travel of the elevator, the elevator can be stopped responding. However, while the elevator is descending toward the second floor, contact U (a2) of the upward direction detection relay is in an open state, so the long wait detection relay HLD is not energized and no deceleration command is given. Therefore, even if the elapsed registration time of a hall call for general passengers exceeds the set time of the long-wait detection timer, the elevator will not stop responding if the direction of the hall call for general passengers is different from the direction of travel of the elevator. . As a result of the above, while registering a hall call button exclusively for physically disabled persons or a destination button in the car, responses to hall calls for general passengers whose registered elapsed time does not exceed the set value are blocked, and the registered elapsed time is set to the set value. Only calls in the same direction as the elevator traveling direction can be answered for general passenger hall calls beyond the elevator. Next, FIG. 4 shows a direction selection circuit for physically handicapped persons constituting an embodiment. A contact S1U of a hall call registration relay in a conventional direction selection circuit exclusively for handicapped persons
(a) ~ S3U (a), S2D (a) ~ S4D (a),
A contacts 1UX (a2) to 3UX (a2), 2DX (a2) of the long waiting detection relay for the general passenger hall call mentioned above
~4DX (a2) are additionally connected in parallel. In the same figure, for example, when the elevator is ascending to pass the third floor, the registration time for the hall call for general passengers on the second floor exceeds the set value, resulting in a long wait, and the long wait detection relay 2UX is energized. ,

Fixed segments 3TL and 4TL through the circuit of [Table]
The voltage of the (+) power supply line PC is applied to.
Therefore, when the elevator reaches the 4th floor, the fixed segment 4TL for detecting the descending direction and the movable brush F6 for detecting the descending direction come into contact, and the movable brush F6 → contact U(b) of the ascending direction detection relay → downward direction. Current flows through the circuit of the direction detection relay D→(-) power line N, and the downward direction detection relay D is energized. This direction selection is similar to the case where the upward hall call registration relay S2U dedicated to physically handicapped persons is energized. In other words, a hall call for which the registration time for a general passenger hall call exceeds a set value and the waiting time is long can be treated in the same manner as a hall call exclusively for physically handicapped people. As a result of the above, while registering a hall call button for physically disabled people or a destination button in the car, responses are blocked for hall calls for general passengers whose registered elapsed time does not exceed the set value, and when the registered elapsed time exceeds the set value. Hall calls for general passengers can be operated in combination with hall call buttons exclusively for physically disabled persons and in-car destination buttons. In the above explanation, one elevator for general passengers and the disabled was described, but it is also possible to apply the control device of the present invention to one elevator that is operating under group management control, and in this case, B contact SHC of call detection relay SHC for physically disabled people
(b2) can be easily realized by separating the general passenger hall call direction selection circuit as shown in FIG. As is clear from the above description, the elevator control device of the present invention can comprehensively shorten the elevator non-response time for hall calls for general passengers that occur due to hall calls for people with physical disabilities. It is possible to reduce the waiting time for general passengers while giving priority to hall calls for physically disabled people, and eliminate the frustration caused by waiting for a long time.
