Abstract

PURPOSE:To attain adequate evacuation guidance at the time of disaster by setting a preferential selective condition of a control operation command, and successively commanding operation group by group, when a fire occurs in an elevator. CONSTITUTION:A story of fire occurrence is separately detected with an elevator service story of each group A to E serving as a reference, and the priority order is added to commanding fire control operation to an elevator to automatically command the fire control operation by the order of priority group. That is, fire time control operation can be commanded by a unit of each group A to E by the order of A B C D E when fire breaks out in the A group, B C D E A when a fire breaks out in the B group, C D E B A when a fire breaks out in the C group, D E C B A when a fire breaks out in the D group and E D C B A when a fire breaks out in the E group. In this way, adequate evacuation guidance can be performed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation system, and in particular, a plurality of elevator groups each including a plurality of units are installed in one building, and all floors of the building are service floors. Regarding the improvement of control operation command at the time of fire of elevator equipment shared as

[0002]

2. Description of the Related Art FIG. 1 is a diagram for explaining an elevator installation installed in one building. The building has up to 50 floors to L _B floor as the lowest floor, elevator group A~E There are a total of twenty elevators are installed composed of the four units. Service floor of the A group is L _B, 2~10 floor, B
Group L _B, 11~20 floor, C Group L _B, 2
1-30 floor, D Group L _B, 31 to 40 floors, E groups are sharing the entire gray L _B, a 41 to 50 floors as service floors.

In addition, the control operation at the time of fire of the elevator is a system unified by each manufacturer by the Elevator Association. It case of fire in each group receives a control operation command, the elevator of the group to stand and not the operation of subsequent to travel to L _B floor is stopped after evacuation floor to the nearest floor. This is intended to prevent secondary disasters caused by elevators.

A conventional embodiment under the above conditions will be described.

FIG. 2 is a circuit diagram showing a conventional embodiment.

L ₁ and L ₂ are power supply busbars, S is a switch installed on an elevator monitor panel or the like to be turned on by a manager when a fire occurs, and f _{2 to} f ₅₀ are installed on each floor corresponding to the floor of the building with the last numeral. The signal contact of the fire alarm is detected to detect the occurrence of a fire and the signal contact on the floor closes, FA to F
The letter E is a fire control operation command relay whose last letter corresponds to the elevator group, and when it is turned on, it commands the elevators in that group to perform control operation during a fire.

Now, assuming that a fire occurs on the 31st floor and the signal contact f _{31 of the} fire alarm is closed, L ₁ -f ₃₁ -FA, F
B, FC, FD, fire emergency operation command relay all groups are turned on by FE-L _2, all groups results in switching Ri L _B floor fire during control operation at once.

[0008]

Such a conventional embodiment has the following problems in a super high-rise, large-scale building as shown in FIG.

[0009] The L _B floor is the evacuation floor from the fact that each group all the base of the elevator results all at once, L _B floor is crowded, is accurate evacuation at the time of such a disaster is difficult.

[0010] In recent years, buildings have improved fire protection compartments and their technology, and the floors below the fire occurrence floor are not affected at all, and the elevators operating there continue to operate normally for ordinary customers. However, even though the configuration has become acceptable, there is the inconvenience of simultaneous fire control operation.

[0011]

[Means for Solving the Problems] In order to solve the above-mentioned problems, priority is added to the order in which fire control operation is instructed to elevators by distinguishing and detecting the fire occurrence floor based on the elevator service floor of each group. Fire control operation is automatically commanded in the order of.

Namely, as a group for the fire occurrence floor and service floors First, by the first group has been completed resulting in the total base L _B floor, a group of upper adjacent to the first group, following further its Sequentially command with upper adjacent groups,
When all the upper groups are completed, the next lower group and the next lower group are automatically instructed sequentially.

[0013]

FIG. 3 is a circuit diagram showing an embodiment of the present invention.
The symbols in the figure are the same as those in FIG. 2 which has already been explained, and the parts which are not explained in FIG. 2 will be explained.

In S _{A to} S _E, the last alphabetic characters correspond to the group,
Switches installed on the elevator monitoring panel for each group, which are turned on by the administrator when a fire occurs, GA _{1 to} GD ₁ , GB ₂
～GE ₂ corresponds to each group ending letters, at transfer contact any at the contact of the relay which is turned on by the group all stand that group receives an instruction of fire emergency operation is resulting complete L _B floor It is configured. The number at the end is the contact number.

Referring now to FIG. 3, a fire broke out on the 31st floor,
When the signal contact f _{31 of the} fire alarm is closed, L ₁ -f ₃₁ -GD ₁
(Break side) -GD ₂ (Break side) -FD-L ₂ turns on the fire control command relay FD and commands the D group to perform fire control operation. When D Group total base Upon receiving the instruction results completed L _B floor, its contacts GD ₁ is switched Ri FD is turned off to the make side, L ₁ -f ₃₁ -GD ₁ (make side) -
The fire control command relay FE is turned on by GE ₂ -FE-L ₂ and commands the fire control operation to the E group. Next, when the E group is completed, L ₁ -f ₃₁ -GD ₁ (make side) -G
E ₂ (make side) -GD ₂ (make side) -GC ₂ (Blake side)
-FC is turned on by FC-L ₂ and command fire control operation to group C. That is, when the group on the fire-occurring floor and then the group above the fire-occurring floor have completed the return, the group below the fire-occurring floor is instructed. Next, when the C group is completed, the B group is instructed, and when the B group is completed, the last A group is instructed.

Thus, when a fire occurs in group A, A → B → C → D → E B 〃 〃 B → C → D → E → A C 〃 〃 C → D → E → B → A D 〃 〃 Fire control operation can be instructed for each group in the order of D → E → C → B → A E 〃 〃 E → D → C → B → A.

[0017]

According to the present invention, in order to solve the problems considered in the conventional system, the elevator group serving the fire occurrence floor is set as the first rank, and the second upper group is sequentially ordered to control the fire control operation in group units. things from, can be done to ease the congestion of L _B floor of the evacuation floor an accurate evacuation.

Even if a fire occurs, the elevator group that serves the lower floors below the fire floor, which is relatively unaffected by the fire, receives a command after the upper floors are completed and can continue normal operation. Although not described in the description in some cases, it is possible to provide an operation switch that is excluded until the fire control operation is commanded by the administrator's judgment.

[0019] While the evacuation floor in the embodiment of the present invention has been described as L _B floor, which may everywhere by the conditions of the building,
Even if several floors are designated, the present invention will not be impeded.
