Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator control device, and in particular,
The present invention relates to an elevator control device suitable for an elevator having a function of preferentially servicing car calls on a specific floor.

[Conventional technology]

Conventionally, by turning on a switch provided on the in-car operation panel, calls from the hall side and already registered car calls were invalidated, and only car calls on specific floors were serviced (hereinafter referred to as dedicated operation). ), the already registered car calls and hall calls were canceled by turning on the switch, and by registering the car call for a specific floor, service was provided to the specific floor. This method cancels calls that have already been registered, so during dedicated operation, passengers who were already in the car need to get off outside the car, and passengers waiting in the hall have their calls turned off. After the dedicated operation ended, it was necessary to register the hall call again.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control device that controls the elevator so that it can service car calls and hall calls that have already been registered, after the dedicated operation ends, without canceling those calls.

[Means for Solving the Problems] The feature of the present invention is that when the switch for exclusive operation is turned on, the already registered calls are memorized as they are, and the system is controlled so that only the car call after the switch is turned on is answered. However, after the dedicated switch is turned off, the system is controlled to service registered calls.

In addition, during dedicated operation, if a response light is already turned on due to a registered car call, the light is temporarily turned off by turning on a switch, and the response light is controlled to be turned on when a call is registered for a specific floor. This clarifies the call registration during dedicated operation. By turning off the dedicated switch, the already registered car call response light is controlled to turn on again.

Next, the operation will be explained. First, normal operation will be explained. Assume that the elevator car is stopped on the first floor and a passenger gets into the car and presses the car call registration button 3 on the in-car operation panel. The car call registration relay 3C on the third floor is P-3-60b ₄ -3Rb ₁ -3C-
It is turned on by the N circuit, and P-3Ca ₃ -3Rb ₁ -3
Self-maintained by C-N. As a result, the car call answering light on the third floor is turned on by A-60b ₆ -3Ca ₄ -3CL-B as shown in FIG. This call starts the elevator, and when it reaches a certain distance before the third floor level, the movable part of the position detector is activated.
When the SDU contacts the fixed piece 3U of the deceleration position detector for ascending operation on the third floor, P-UP-SDU-3U-
3Ca ₁ -60b ₁ -SD-N for deceleration operation relay
The SD turns on and the elevator slows down and stops on the third floor. When the car stops on the 3rd floor, the 3rd floor call reset relay 3R (relay circuit omitted) turns on, and the 3Rb ₁ contact of the 3rd floor call relay circuit opens, which turns off the call relay 3C and resets the car on the 3rd floor. The call answering light CL3 also goes out.

Next, the dedicated operation will be explained. If the elevator car is stopped on the 1st floor and the 2nd and 3rd floor car calls and the ascending calls for the 2nd floor hall have already been registered, and you want to perform dedicated operation for the 4th floor car call, turn on the dedicated switch. Before turning on, car call registration relay 2C on the second floor was P-2Ca ₃ -2Rb ₁ -2C
-N, the car call registration relay 3C on the 3rd floor is set to P.
-3Ca ₃ -3Rb ₁ -3C-N, respectively.
self-retaining. Further, the hall's upward call relay 3HU (explanatory diagram omitted) is also turned on. The car call response light on the in-car operation panel is A-60b ₆ -2Ca ₄ -
CL2-B and A- _60b6-3Ca4 - _CL3 -B
Due to this, the car call response lights on the second and third floors are on. When the dedicated operation switch SW is turned on, P-SW
-60-N turns on the dedicated operation relay 60,
Car call response lights CL2 and CL3 on the 2nd and 3rd floors
The light goes out when the 60b ₆ contact opens. In addition, the closing circuit of the deceleration operation relay SD is connected to car call relay contacts 2Ca ₁ , 2Ca ₂ , 3 on the 2nd and 3rd floors.
Ca ₁ , 3Ca ₂ and the second floor hall ascending call relay contact 2HUa are closed, but the dedicated operation relay 60 is turned on and its contact 60b ₁ is open, so the deceleration operation relay SD is turned on. Can not. Therefore, car calls and hall calls during normal operation will not be serviced temporarily. On the other hand, for car calls after the dedicated operation switch is turned on, the car calls will be operated exclusively for the car and will be serviced regardless of other calls. If you press the car call registration button on the third floor now, P-3-60a ₅
-3Rb ₂ -3D-N circuit allows 4 during dedicated operation.
Floor car call relay 3D turns on, P-3Da ₃ -3
Self-maintained by Rb ₂ -3D-N circuit. Furthermore, the car call answering light CL3 is A-60a ₆ -3Da ₄ -
CL3-B lights up to clearly indicate that the call will be answered. The elevator starts, and when the movable piece SDU of the deceleration position detector contacts the fixed piece 3U of the position detector for ascending to the third floor, P-UP-SDU-3U-3
The Da ₁ -60a ₁ -SD-N circuit turns on the deceleration operation relay SD and the elevator decelerates to a stop.
When the dedicated operation is completed, the user turns off the dedicated operation switch and the dedicated operation relay 60 is turned off.
By turning off relay 60, the car calls and hall calls that were temporarily disabled during normal operation become effective, their registered response lights are lit again, and the respective contacts of the deceleration command circuit are also enabled. Elevators will be serviced sequentially.

〔Effect of the invention〕

According to the present invention, temporary dedicated operation for emergencies can be performed without canceling already registered calls or without disembarking other passengers, and the dedicated operation switch can be activated. After the service is turned off, it has the remarkable effect that registered calls can be serviced.

Furthermore, during dedicated operation, the response lights for calls that have already been registered are temporarily turned off, making it possible to clearly determine the registration of car calls and their responses during dedicated operation.
