【Example】

Example 1. Hereinafter, the present invention will be described based on illustrated embodiments. First Embodiment FIG. 1 is a conceptual configuration diagram showing an elevator running-time controller according to a first embodiment of the present invention. In FIG. 1, the same parts as those in the conventional example shown in FIG.
Is an elevator hoistway, 2 is an elevator machine room located directly above the hoistway 1, 3 is a pit at the bottom of the hoistway 1, 4 is an elevator car, and 5 is a doorway of the hoistway 1. A hall on each floor, 6 is a control cable for movement that electrically connects the car 4 and a control device 7 installed in the machine room 2, and 7 is a control having a microcomputer 8 as control means. The device 9 is, for example, a parking switch which is provided at a hall on the reference floor and is operated from the outside.

Further, as new codes, 11 is a first water flow sensor arranged on the car 4, 12 is a pit 3
Is a second water flow sensor disposed on the floor surface of the control device 7, and the detection outputs of the water flow sensors 11 and 12 are the control device 7
It is input to a microcomputer 8 therein, and the microcomputer 8 performs evacuation control and upper floor service control according to the detection outputs of the water flow sensors 11 and 12. Note that, in FIG. 1, in the flooded state A, the car 4 is retracted to the evacuation floor, which is the top floor, based on the output detected by the water flow sensor 12.

Here, as shown in FIG. 2, the microcomputer 8 in the control device 7 has an interface 8A for receiving the detection outputs of the water flow sensors 11 and 12 and an input signal from the parking switch 9, and an interface 8A based on these inputs. And a CPU for controlling the operation of the car 4 based on the program stored in the memory 8B.
8C and, as will be described later, the operation of the car 4 is controlled to the evacuation floor based on the detection output of the water flow sensor 11, and the car 4 is serviced to the upper floors based on the detection output of the water flow sensor 12. Operation control.

Next, referring to the flow chart shown in FIG. 3, which shows the control operation by the CPU 8C for controlling the operation of the car 4 on the basis of the program stored in the memory 8B, the operation of the control device for running water of the elevator according to the above configuration. And explain. First, in step S101, when the running water sensor 11 installed on the car 4 detects running water of rainwater falling on the car, the detection output causes the evacuation according to the program stored in the memory 8B of the microcomputer 8 in advance. Floor waiting control is performed (step S10).
5). Accordingly, the car 4 is switched from the normal operation to the evacuation operation to the evacuation floor. If there is no rainwater flow detection on the car 4, the process proceeds to step S102.

Next, in step S102, when the detection of running water (flooding) to the pit 3 is output by the running water sensor 12, the process proceeds to step S104, and step S104.
If the parking switch 9 has already been turned on, in this case, a cancellation command is issued to the parking on the lowermost floor, and the process proceeds to the upper floor service control (step S10).
9). That is, when the pit is flooded, the service to the lowest floor is stopped and only the upper floors can be operated.

In step S102, if the parking switch 9 is turned on while the running water sensor 12 does not output the running water (flood) to the pit 3, the parking floor standby control is performed (step S10).
3, S107), on the other hand, if the parking switch 9 is turned off, the normal operation is performed as the response floor standby control (steps S103, S106). In addition, the above step S1
In 04, if the parking switch 9 is off,
In that state, the operation shifts to upper floor service control (step S).
109).

By the above-mentioned control operation, when running water on the car 4 is evacuated, flooding is prevented to a minimum and insulation deterioration of peripheral devices of the car 4 is reduced. In addition, when the pit 3 is flooded, the water under the car 4 and the control cable 6 is prevented from being flooded, while if only the pit 3 is flooded, it is possible to operate on the upper floors so that the service operation is maintained. .

Therefore, according to the first embodiment, information on running water on the car 4 or running water (flooding) into the pit 3 can be fetched as a signal to automatically enable the evacuation control or the service floor shift control. So, for example, it is possible to dismiss the waiting on the lowest floor and dispose of unnecessary evacuation pauses without the need for running water, and to accurately detect the running water condition due to rainwater around the car and pits. Appropriate control that is not adversely affected by running water can be performed.

Example 2. In the first embodiment described above,
In the evacuation floor standby control by the detection output of the running water sensor 11 on the car, the evacuation control is performed during the detection output, and the standby is continued. Therefore, it is necessary to cancel this. In the second embodiment, as shown in FIG. As shown, a release switch 13 composed of a switch body is provided in the control device 7, and when the release switch 13 is turned on, a computer control having a program of a release command for the evacuation floor standby control is executed.

That is, FIG. 5 is a flow chart showing the control operation according to the second embodiment corresponding to the control operation of the first embodiment shown in FIG. 3. Here, the difference from the first embodiment is step S110. With the release switch on,
The cancellation of the evacuation floor standby control in step S105 is released, and the response floor standby control in step S106 is executed. This release operation can be canceled by the elevator maintenance staff by judging the current situation.

[0023]
