Abstract

PURPOSE:To simplify the operation in an elevator driven between the upper and the lower floors by performing a cage calling registration when a stop calling takes place and a passenger in the cage is detected. CONSTITUTION:If a user on the first floor presses a first-floor stop calling button 3, a first-floor calling register relay is energized and self holds through a first-floor position detecting relay contact 8 and a self holding contact 4ao. In case an elevator stands by on the second floor, the elevator is driven down to the first floor, stops, then a door closure detecting relay contact 7 closes the circuit by the door opening, and the relay 4 continues to maintain the self holding state. When the user gets into the elevator, a load detector contact 2a is closed, an ascending direction selecting relay 10 is energized through a normally opened contact 4a, self holds at a self holding contact 10a. When the elevator door is fully closed, the door closure detecting relay contact 7 is opened, the first floor calling register relay 4 is de-energized, and the elevator is driven toward the second floor. The simplification of the operability can be thus attained.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides an elevator system that automatically performs car call registration for an elevator operated between a lower floor and an upper floor. Regarding a control device.

(Prior art) Conventionally, elevator call registration has been carried out using the following method. , a system in which an elevator car is called, the user gets into the car, registers the destination floor (car call registration) using the destination button on the car operation panel installed inside the car, and goes to the destination floor.

(b) A method in which a destination floor reservation button is provided at the elevator landing on each floor, and the user presses the destination floor reservation button in advance to register a call and go to the destination floor.

(C) A method in which a receiver is installed in the elevator hall of each floor, and a specific user carries a transmitter, registers a call using a preset transmission and reception method, and goes to the destination floor.

(Problem to be Solved by the Invention) Among the above three methods, (a) is a method adopted within the membrane, in which the user registers a hall call, gets into the car, and then returns to the car. Press the destination button on the control panel to register the car call and operate the elevator to the destination floor. This method is effective when the elevator stops on the 3rd floor or higher, but in the case of an elevator that operates between the upper and lower floors, when boarding from the 1st floor, only upward operation is possible, and when boarding from the 2nd floor, the elevator only operates upward. In this case, two operations were required: a landing call and a car call, even though the car only operated in a descending manner.

Next, methods (b) and (C>) are very convenient for users who can make reservations in advance, but the systems are complicated and expensive, so they are not suitable for use with home elevators, which have become popular in recent years. There are problems in terms of equipment costs and space, and in particular, home elevators installed in two-story buildings have the disadvantage of being relatively expensive.

As described above, in conventional control devices, especially in platform elevator control devices for two-story buildings, when registering a call, the call registration operation must be performed in two steps: hall call and car call. This is not suitable for home elevators because it is difficult to operate for people with disabilities or people with disabilities, and the method of reserving a call in advance is expensive due to the equipment.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator control device that can be operated more simply and that allows call registration at low equipment cost.

[Structure of the invention]

(Means for Solving the Problems) The elevator control device of the present invention includes a hall call operation means provided at the landing of each floor, a detection means for detecting whether or not there is a passenger in the elevator car, and a hall call operation means provided at the landing of each floor. The present invention is characterized by comprising a registration means for registering a car call when a hall call is made by the means and the presence of a passenger in the elevator car is detected by the bulge detection means.

(Function) According to the above configuration, the elevator can be operated only by operating the hall call without operating the car call.
It is possible to simplify call registration when the number of floors to be stopped is two, such as a home elevator installed in a two-story building.

As a result, the call registration operation for wheelchair users, disabled users, elderly people, etc. is simplified, and even these users can easily use the elevator fully.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

First, refer to FIG. Figure 2 shows the [
This schematically shows a structure in which a load detector 2 is provided on the floor of an elevator car 1 to detect when the car load exceeds a predetermined value.

When the load detector 2 detects that the car load has exceeded a predetermined value, the load detector contact 2a (see FIG. 1) closes.

FIG. 1 shows an embodiment of the present invention.

Here, the first floor call registration relay 4.2 is used as a control relay that can be energized by the voltage between a pair of control power supply buses P and N.

The descending direction selection relay 11 is an energizing circuit consisting of a series circuit of the normally open contact 2a of the load detector 2 and the normally open contact 6a of the second floor call registration relay 6, which has a self-holding normally open contact 11a connected in parallel. energized by.

The operation of the control device of FIG. 1 configured as above will be explained with reference to FIG. 3 (flowchart).

First, a case where an elevator user tries to go from the first floor to the second floor will be explained.

When a user on the 1st floor presses the 1st floor hall call button 3, the 1st floor call registration relay 4 is energized and self-holds via the 1st floor position detection relay contact 8 and self-holding contact 4ao (Fig. 3). Step 20-Step 21: “Y”). If the elevator is waiting on the second floor (step 22: “
Y"), the elevator is thereby operated from the second floor to the first floor by an operation circuit not shown (step 23).
After landing on the first floor (step 24), the elevator door is opened (step 25), allowing the user to enter the elevator. If the engineering 1 innovator is waiting on the first floor from the beginning (step 22: "N"), step 23
．． 24 and directly from step 22 to step knob 2.
5 and the door opening operation is performed.

When the Noveta arrives on the first floor, the first floor position detection relay contact 8 opens with a slight delay. However, before the opening, the door closing detection relay contact 7 closes due to the closing of the door, so the first floor call registration relay 4 continues to maintain its self-holding state. Here, when the user gets into the car 1 and becomes a passenger in the elevator, the normally open contact 2a of the load detector 2 closes and rises via the normally open contact 4a of the 1st floor call registration relay 4. The direction selection relay 10 is energized and becomes self-holding via the self-holding contact 1.0a (step 27). Next, the elevator door is fully closed (step 28).
; Since "Y") and the door close detection relay contact 7 are opened, the first floor call registration relay 4 is deenergized. Step 26 unless the door is fully open (step 28° “N”)
~Cycle through 28 loops. If the user does not get into the car 1-, the result in step 26 is "N", and the door is checked to close (step 29), and if the door does not close (step 29, "N"), the process returns to step 26 and the door is closed. (Step 29: "Y"), the basket 1 remains on standby on the first floor (Step 30). Now, in step 28, the closed state of the door is confirmed (step 28: 'Y
''), the ascending direction has already been selected by the ascending direction selection relay 10 (step 27), so the elevator is operated toward the second floor by the non-illustrated operation circuit (step 31), and the elevator reaches the floor. (Step 32) The rear door is opened (Step 33).When the user gets off the car 1, the load detector 2 detects this and the load detector contact 2a opens (Step 34. "Y"). , the upward direction selection relay 1o is deenergized (step 35), and after the door is closed (step 36), the circuit returns to its original state, and the car 1 remains on standby on the second floor (step 37).

Next, a case in which an elevator user goes from the second floor to the first floor will be explained.

When the elevator user presses the 2nd floor hall call button 5, the 2nd floor call registration relay 6 is energized and self-holds via the 2nd floor position detection relay contact 8 and self-holding contact 6ao (steps 20-21). N''). 1 elevator
If the elevator is waiting on the floor (Step 42: Y"), the elevator is operated from the first floor to the second floor by the operation circuit (Step 43), and the elevator is stopped at the second floor (Step 4).
4) After that, the elevator door is opened (step 45), and the user can enter the elevator. If the elevator is waiting on the second floor from the beginning (step 42. “N
'') skips steps 43 and 44 and directly jumps from step 42 to step 45 to close the door. When the elevator lands on the second floor, the second floor position detection relay contact 9 opens with a slight delay. However, before the opening, the door close detection relay contact 7 closes due to the opening of the door.
Floor call registration relay 6 continues its self-holding state.

When the user gets into the car, the normally open contact 2a of the load detector 2 is closed (Step 46: "Y"), and the upward direction selection relay 10 is activated via the normally open contact 6a of the second floor call registration relay 6. It is energized and self-holds via the self-holding contact 10a (step 47).

Next, the elevator door is fully closed (step 48: “Y”)
) and the door close detection relay contact 7 are opened, so the second floor call registration relay 6 is deenergized. The door does not open fully (
Step 48: The loop of steps 46 to 48 is repeated as long as the user does not get into the car 1.If the user does not get into the car 1, the result is "N" in step 46, and the door is confirmed to be closed.Step 49) The door does not close (step 48) 49: “N
"), the process returns to step 46, and when the door is closed (step 49: "Y"), basket 1 remains on standby on the second floor (step 50). Now, in step 48, it is confirmed that the door is closed (step 48 : "Y"), and the descending direction has already been selected by the descending direction selection relay 11 (step 47), so the Nirebeta is driven toward the first floor by the driving circuit (step 51), and it lands on the floor (step 5).
2) The rear door is opened. When the user gets off the car, the load detector 2 detects this, and the load detector contact 2a
is opened (step 54: "Y'), the lowering direction selection relay 11 is deenergized (step 55), and after the door is closed (step 56), the circuit returns to its original state, and car 1 It remains on standby on the first floor (step 57).

As mentioned above, you can operate the elevator to the 2nd or 1st floor simply by pressing the hall call registration buttons 3 and 5 on the 1st or 2nd floor and getting into the elevator car. The user can go to the destination floor without pressing the destination floor registration button on the car operation panel, simplifying the operation, and eliminating the inconvenience of elevator users.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with appropriate modifications within a scope without changing the gist. For example, in the above-described embodiment, call registration is performed using the hall call button, but instead, a sensor, such as an ultrasonic A sensor may be installed to perform call registration when it is detected that a user has been in the car as a passenger for a certain period of time.

Further, although the above embodiment is an example of an elevator operating between the first floor and the second floor, the present invention is not limited thereto, and the present invention is not limited to this, but is applicable to elevators operating between two specific floors, for example, a 10-story building. It can also be applied to elevators that operate non-stop between the 1st floor and the 10th floor.

〔Effect of the invention〕

According to the present invention, elevator users only need to register for a hall call, and once they get into the elevator car, they will automatically ascend or descend toward their destination floor, which is particularly effective for users with disabilities in their limbs. Even users who are unfamiliar with elevator operation can use the elevator with confidence. Therefore, for example, when applied to home elevators, the demand for which has been increasing in recent years, it can be used with confidence even by users with physical disabilities or the elderly by achieving simple operability at low equipment costs. can do.
