Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car having a maintenance control device for outputting various control command signals at the time of maintenance and inspection.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Utility Model Laid-Open No. 50-13616, there has been proposed an elevator maintenance control device for controlling various devices on the upper part of a car during maintenance inspection.

[0003]

In the prior art described above, when two operators perform maintenance and inspection of the elevator, the operator who operates the maintenance control device on the car speaks for ensuring safety. It was like this. For example, when attempting to drive the car upward, a shout "up" is issued, and the operator operates the maintenance control device only when another worker repeats in response to the shout. It was On the other hand, when only one operator performs maintenance and inspection of the elevator, there is no need to make a call as described above, so the attention during maintenance and inspection tends to be relatively distracting, which is unfavorable for safety. It was

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to provide an elevator car capable of enhancing the safety of work during maintenance and inspection.

[0005]

To achieve this object, the present invention relates to an elevator car equipped with a maintenance control device for outputting various control command signals at the time of maintenance and inspection, in which the control command signals An audio output device that selectively outputs various audio signals in response to the audio output device, and a speaker that broadcasts a guide message based on the audio signal output from the audio output device, and various devices based on the control command signal. When the control is performed, the contents of this control are announced by the speaker.

[0006]

Since the present invention is configured as described above, when an operator operates the maintenance control device on the car during maintenance and inspection,
Various audio signals are selectively output from the audio output device according to the control command signal output from the maintenance control device. For example, when attempting to raise or lower the car, a guide message for calling attention or a guide message for reconfirming operation is broadcast by a speaker based on the audio signal output from the audio output device. That is, when various devices are controlled by the output of the control command signal, the contents of the control are announced by the speaker. As a result, in the case where only one worker performs maintenance inspection in the car, it is possible to improve the safety of the worker by preventing looseness during maintenance inspection by the broadcast guide message. it can. Also,
When two people perform maintenance inspections in the car, even if the operator who operates the maintenance control device forgets to shout, the above-mentioned broadcast guidance message warns the operator and informs of the operation. Since it is possible to prompt reconfirmation, it is possible to enhance the safety of work during maintenance and inspection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the elevator car of the present invention will be described below with reference to the drawings. 1 is a side view showing an embodiment of an elevator car of the present invention, and FIG. 2 is a block diagram of a maintenance control device and a speaker provided in the car of FIG.

On the upper part of the car 1 of the present embodiment shown in FIG. 1, a maintenance control device 2 for outputting a control command signal at the time of maintenance and inspection, and various voice signals selectively according to the control command signal. A voice output device for outputting, for example, a voice synthesizer 3
And a speaker 4 that broadcasts a guide message based on a voice signal output from the voice synthesizer 3. The maintenance control device 2 is connected to an operation unit 5 having an up button 5a, a down button 5b, etc., and the voice synthesizer 3 is provided with a plurality of signal lines 6a as shown in FIG.
~ 6n are connected. For example, the rise button 5 of the operation unit 5
When a and the down button 5b are operated, the control command signal output from the maintenance control device 2 is input to the voice synthesis device 3 via the signal lines 6a and 6b, respectively. Further, when the door 7 of the car 1 is opened, a door open signal is input to the voice synthesizer 3 via the signal line 6m, and similarly, when the door 7 is closed, a door close signal is input via the signal line 6n. It

In this embodiment, when the operator gets on the car 1 at the time of maintenance and operates the lift button 5a of the operation unit 5 to raise the car 1, for example, the maintenance control device 2 Since the control command signal is input to the voice synthesizing device 3 via the signal line 6a, the voice synthesizing device 3 selectively outputs the voice signal, and a guidance message for calling attention by the speaker 4 based on the voice signal, for example, The guidance message "I will rise" will be broadcast. Then, the ascending operation of the car 1 is performed according to the control command signal. Similarly, when the lowering button 5b of the operation unit 5 is operated, a descending operation of the car 1 is performed after the guidance message "I will descend" is broadcast by the speaker 4.

When the door 7 of the car 1 is opened, the door open signal is input to the voice synthesizer 3 through the signal line 6m, so that the voice synthesizer 3 selectively outputs the voice signal. Based on this audio signal, a guide message for calling attention, for example, a guide message "door opens" is broadcast by the speaker 4, and then the door 7 is opened in response to the door open signal. Similarly, when the door 7 is closed, a door closing signal is input via the signal line 6n, and after the guide message "Door is closed" is broadcast by the speaker 4, the door 7 is closed.

In the embodiment thus constructed, for example, when the up button 5a of the operating section 5 is operated, a guide message "I will go up" is broadcast by the speaker 4, so that the operation of the operating section 5 is appropriate. You can check whether it is a thing. In the unlikely event that the down button 5b is operated by mistake, a guide message "Descent" will be broadcast, so the down button 5
By suspending the operation of a, the descending operation of the car 1 can be prevented. Also, before starting the opening / closing operation of the door 7,
Since the guide message "door opens" or "door close" is broadcast by the speaker 4, the door 7 is prevented from opening and closing suddenly, and an accident such as an operator being caught in the door 7 can be prevented. Therefore, when only one person performs maintenance / inspection on the car 1, it is possible to prevent the air from loosening at the time of maintenance / inspection and improve safety by the broadcast guide message. In addition, two people cage 1
When performing maintenance inspections at the
Even if the operator who operates the device forgets to shout, the above-mentioned guidance message can call attention or reconfirm the operation, so that the safety can be improved.

[0012]

Since the present invention is configured as described above, when one person alone performs maintenance and inspection in a car, broadcasting of a guidance message can prevent slackness during maintenance and inspection. Also, when multiple operators perform maintenance inspections in the car, even if the operator who operates the maintenance control device forgets to shout, the above-mentioned guidance message warns the operator and Reconfirmation can be prompted.
Therefore, the safety of the work can be improved when performing maintenance and inspection on the car.
