Abstract

PURPOSE:To automatically communicate with a dispatching company when a work support is required by providing a communication unit for judging an abnormal state when a switch is on operation state even after an alarm device alarms for a determined time and outputting it as an abnormal data to a telephone circuit. CONSTITUTION:A communication unit 16 provided in a machine room operates an alarm device 21 to inform a maintaining person of this effect when the operating state of a switch 9 is continued for a determined time or more after it is operated, and also judges an abnormality when the switch 9 is laid in the operating state after the alarm device 21 alarms for a determined time to inform a monitor center 20 of this effect by a telephone circuit 19. Thus, not only the maintaining person can know that he takes a determined time or more for the work, but also the data of this effect is automatically transmitted to the monitor center 20 when a support is required, so that a necessary countermeasure can be immediately taken. The time to search around for a telephone is not required, and unworked time can be eliminated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator work support requesting device.

[Conventional technology]

Elevator accidents not only cause great inconvenience to people who use the elevators, but also can lead to personal injury. For this reason, elevators are inspected by maintenance personnel at predetermined intervals not only when an accident occurs, but also during normal times.

Maintenance personnel are dispatched from the office that has jurisdiction over the elevator and patrol and inspect the elevators they are responsible for. This maintenance and inspection is usually carried out by humans, and may involve inspection work in the machine room, in the pit, or on the car.Depending on the work, it may be difficult to do it alone, so you may need to request support. be. In this case, the maintenance worker would search for a telephone in the building attached to the elevator or in another location and contact the dispatch company accordingly.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, depending on the location of the telephone, work must be interrupted for a long time, resulting in a large amount of downtime for the operator and the customer, which causes great inconvenience to the customer.

Furthermore, depending on the work, it is not possible to leave the elevator, and even if work support is required, there is a problem in that the user cannot request it. Furthermore, there was a problem in that maintenance personnel were so engrossed in their work that they did not request assistance even though it was necessary, and time was wasted unnecessarily.

An object of the present invention is to provide an elevator work support requesting device that automatically contacts a dispatch company when work support is required.

[Means to solve the problem]

In order to achieve the above purpose, a switch and an alarm device are provided in at least one place in the machine room, car, or bit of the elevator; count and
a reporting device that activates the alarm device when a predetermined period of time has elapsed, and determines that an abnormal state is occurring when the switch is in an operating state even after the alarm device has issued an alarm for a predetermined period of time, and outputs the abnormal data to a telephone line; and a monitoring center that receives the abnormal data and takes action.

[Effect]

The notification device installed in the machine room has a switch activated,
If this operating state has elapsed for a predetermined period of time or more, the alarm device will be activated and maintenance personnel will be notified of this, and if the switch remains in the operating state even after this alarm device has issued an alarm for a predetermined period of time, it will be determined that an abnormality has occurred. The monitoring center is then contacted via a telephone line. Therefore, not only can maintenance personnel know when their work is taking longer than a predetermined amount of time, but if a request for assistance is required, the data to that effect is automatically sent to the monitoring center, and the necessary information is immediately sent to the monitoring center. You can measure your response. Furthermore, there is no need to spend time searching for a telephone, and downtime can be eliminated.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall schematic diagram of an elevator maintenance worker work support requesting device according to an embodiment of the present invention, and FIG. 2 is a block diagram according to an embodiment of the present invention.

In the figure, 1 is an elevator car that goes up and down a hoistway 2, 3 is a pit installed at the bottom of the hoistway 2, and 4 is a buffer provided in the pit 3.

Reference numeral 5 denotes a car operation panel provided in the car 1, and 6 indicates a movable cable connected to the car 1 via a control panel 8 provided in the machine room 7. 9, 10, 11゜12 is machine room 7
This is a switch that is installed on the bit 3, on top of the car 1, in the lower box of the car operating panel 5, and operated by elevator maintenance personnel. 21゜22.23.24 is machine room 7. This alarm device is installed in the bit 3 on top of the car 1, in the lower part of the box of the car operation panel 5, and notifies elevator maintenance personnel that a predetermined time has elapsed. 13, 14.14a.

A communication line 15 connects the switches 9, 10, 11.12 and the alarm devices 21, 22, 23.24 to the notification device 16 provided on the control panel 8.

The notification device 16 is connected to the switch 9, 10, 11° 12
The control device 17 includes a built-in timer 17a that receives a signal and measures a certain period of time, and a communication station 18 that outputs a signal from the control device 17 to a telephone line 19. Reference numeral 20 denotes a monitoring center that receives signals from the telephone line 19 and allows an operator to take necessary actions.

When working in the machine room 7, the maintenance worker sets a predetermined work time on the timer 17a that is appropriate for the work before starting the work, and then activates the switch 9. Since it is in operation, a timer 17a in the control device [17] measures the operating time of the switch 9, and when the timer 17a of the control device 17 reaches a predetermined time, first, the alarm device 21 notifies maintenance personnel of this fact. At this time, if the maintenance staff determines that support is not necessary, by returning switch 9, the timer 17a is reset and no support is requested. However, if the maintenance staff feels that support is necessary and does not return switch 9, Control equipment! ! 17 determines that it is in an abnormal state, outputs it as abnormal data to the telephone line 19 via the communication device 18, and reports it to the monitoring center 20. When the operator of the monitoring center 20 learns that there has been a request for assistance from a maintenance worker, the operator of the monitoring center 20 can report the assistance request to the sales office in charge and send another maintenance worker to the elevator in question for assistance.

This saves time such as searching for a telephone, and since a request for assistance can be automatically made after a predetermined period of time has elapsed, it is possible to shorten the downtime of the elevator.

This can be done in the same way when working on car 1, inside car 1, and in pit 3 by operating switches 10, 11, and 12.

In the above-mentioned embodiment, switches were provided at four locations: in the machine room 7, on the car 1, inside the car 1, and in the pit 3, but the number of switches does not necessarily have to be four, and they can be selected and provided as appropriate. . Also, although we have shown an example of newly installed as a reporting device,
A remote monitoring device in a building or a remote monitoring device that has recently been installed in a machine room may be used as a reporting device.Furthermore, although the monitoring center is used as a reporting destination, the sales office to which the maintenance staff belongs may also be used. Alternatively, the remote monitoring device may have a built-in switch so that a maintenance person can activate the switch before starting maintenance.

〔Effect of the invention〕

According to the present invention, when a maintenance worker needs work support, he or she can be immediately informed of the need, and the necessary measures can be taken quickly, thereby reducing the downtime of the innovator. Furthermore, the maintenance personnel can know that the work has been completed for a predetermined period of time and can automatically request assistance.
