Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elevator control device having an elevator non-stop floor registration function.

[Technical background of the invention]

In general, in elevators that go up and down multiple floors, it may be necessary to restrict the arrival of a car (car) to a specific floor or the number of calls from a specific floor, due to differences in the business style of each floor of a building. If this restriction is to be fixed in the future, that floor can be designed as a non-stop floor from the beginning, but depending on the building situation, a stop floor may become a non-stop floor due to time of day, day of the week, changes in tenants, construction, etc. It may be necessary to change the non-stop floor. Conventionally, in order to meet such demands, the following non-stop floor control devices have been provided. In other words, conventionally, one or more non-stop switches were installed in the switch box of the car operation panel, depending on the non-stop floor, and when operated, the car call or hall call registration circuit for that floor was disconnected by a relay contact, etc. , configured to disable call registration. In other words, the structure is such that as a result of being unable to register a call, it is also impossible to stop at that floor.

However, this method has the following drawbacks.

(a) Switchable floors are fixed in the original design;
If not all of them are switchable, there will be restrictions on changing the non-stop floors even if there is a change in tenants, for example.

(b) If there are many places where switching is required, a correspondingly large number of changeover switches must be provided in the operation panel switch box. Therefore, the configuration is complicated and space is limited.

(c) It is necessary to design a non-stop floor switching circuit each time depending on the combination of non-stop floor settings.

In order to overcome these drawbacks, a method has been proposed in which a logic circuit is used to set the non-stop floors and a car call registration switch is shared for setting or switching the non-stop floors.

Figure 1 shows an example of this, in which the car call registration switch K is turned on with the switch S turned on.
When (i) is pressed (turned on), the output of gate a becomes "1", the non-stop condition is stored in the memory circuit consisting of gates b and c, and the output of gate d becomes "0", so the car The signals of call switch K(i) and hall call switches D(i) and U(i) are blocked by gates e, f and g and are not registered. Further, by pressing the switch RS (turning it off), the memory circuits of gates b and c are reset and the non-stop condition is canceled. In this case, each switch is of a so-called self-return type, which returns to a steady state when the finger that pressed it is released.

As mentioned above, there have been proposals regarding the method of registering a non-stop floor, but in order to cancel it, it is necessary to manually operate a reset switch. If the car stops and a passenger gets off the car, a problem arises in that the passenger cannot board the car again because he or she is prohibited from calling the car.

[Purpose of the invention]

An object of the present invention is to enable a car to stop at a non-stop floor, open the door, and allow a passenger to board the car again by calling the hall for that floor. An object of the present invention is to provide an elevator control device that can eliminate problems.

[Summary of the invention]

The present invention is characterized in that when the car stops at a floor where it does not stop and once the door is opened, the prohibition condition for hall calls on that floor is lifted.

[Embodiments of the invention]

2 and 3 show the configuration of an embodiment of the present invention, and FIG. 2 shows the non-stop floor registration section,
FIG. 3 shows a non-stop condition reset signal generation circuit when the vehicle stops at a non-stop floor.

In FIG. 2, the same parts as in FIG.
Both of the circuits constituted by c' are non-stop condition memory circuits, and the first non-stop condition memory circuit consisting of gates b and c is reset only by reset switch RS, and the first non-stop condition memory circuit consisting of gates b' and c' In addition to being reset by the reset switch RS, the non-stop condition storage circuit No. 2 is also reset by the reset signal RSSi (i=1,
2, 3...Z).

In Fig. 3, h~1 is a gate, which is configured to generate reset signals RSS1, RSS2,...RSSZ for canceling the non-stop state from the running signal UD, door status signal DooR, and car position signals 1F, 2F,...ZF. has been done. RSS1, RSS2, . . . are condition reset signals for the first floor, second floor, . . . , respectively.

Next, the operation in such a configuration will be explained.

First, registration of non-stop floors will be explained.

In FIG. 2, when set switch S is turned on, one of the inputs of gate a becomes "1". In this state, when the car call registration switch K(i) is pressed, the other input of gate a becomes "1" and the output also becomes "1". One of the inputs of gates c and c′ is “1”
Therefore, its output also becomes "1", which becomes the input to gates b and b'. Since the other inputs of gates b and b' are all "1", the outputs of gates b and b' are "1", and the outputs of gates c and c' are "1".
is maintained and the non-stop condition is memorized. In this way, the inputs of gates d and d' become "1" and their output becomes "0", and one input of gates e, f, and g becomes "0", so the call registration switch K(i), U
(i), D(i) signals are blocked by gates e, f, g, and call registration outputs KC(i), UC(i), DC
(i) is not conveyed.

In such a situation, the call for the (i)th floor is not registered and the car normally does not stop at the (i)th floor, but if an emergency forced stop occurs, the car will stop at the (i)th floor. When the vehicle stops, the signal UD indicating running in the circuit shown in FIG. 3 becomes "0", and when the door opens, the door status signal DOOR becomes "0". Therefore, the output of gate h becomes "1". At this time, assuming that i=3 and the car has stopped on the third floor, the car position signal 3F becomes "1". For this reason,
Both inputs of gate k become “1” and output RSS3
becomes “0”. NAND gates other than gate k, that is, gates i, j, l, etc., receive signals 1F, 2F, 4.
F...(Z) Since F is "0", the output is kept at "1".

If the conditions are met in this way, RSS(i) is “0”
Therefore, in Fig. 2, one of the inputs of gate b' becomes "0", so the memory circuit by gates b' and c' is reset, and gates f and g, that is, only the hall call gates are opened, and it is possible to register the call. .

This will prevent accidents where passengers get off at a floor that is partitioned off by shutters, etc., or have inadequate entrances and stairs due to construction, construction, etc., and are stuck in the elevator without being able to get back on the elevator. can be prevented, improving safety.

Although the above embodiment is constructed using a hardware logic circuit, it is also possible to use a microcomputer, including the call registration section, to perform program processing for setting, resetting, and non-stop processing of non-stop floors. .

In Fig. 4, MC is a microcomputer, K1, U1, D1...D(Z) are car call registration switches K(i), ascending hall call registration switch U(i), descending hall call registration switch for each floor. D(i). RSP is a call response command signal, and although inputs corresponding to the position signals 1F, 2F...(Z)F in Fig. 3 are not shown, they are input from the outside or based on signals input from the outside. It is assumed that this is required inside the microcomputer MC.

FIG. 5a is a flowchart of a routine for setting and resetting a non-stop floor, and FIG. 5b is a flowchart of a routine for canceling a non-stop condition for a stop floor. Each of the routines shown in FIGS. 5a and 5b is repeatedly executed at fixed time intervals, and has substantially the same functions as those explained in the above embodiment, so a detailed explanation will be given here. is not explained.

In addition, the present invention can be implemented with various modifications without changing the gist thereof.

For example, in the above case, when the vehicle stops on a floor registered as non-stop, the non-stop registration is canceled on the condition that the door is opened.However, in a system where the door is predicted to open due to the stop, the non-stop registration is set as the condition of stopping, without the door opening as a condition. The non-stop registration may be canceled, and although the non-stop registration may be canceled at least in response to a hall call as described above, the non-stop registration may be completely reset.

〔Effect of the invention〕

Advantageous Effects of Invention According to the present invention, it is possible to provide an elevator control device that can effectively eliminate the inconvenience caused by setting a non-stop floor and improve safety for passengers.
