Problems solved by technology

[0037] But, when the passenger 36 in the elevator car 3 wants to obtain additional information from the operator of the monitoring center 38, it must be reported to the elevator car 3 from the monitoring center 38.
If such a situation occurs simultaneously in a plurality of remote monitoring devices 2 sharing the public telephone line 8, the sending of a call from the monitoring center 38 of the elevator maintenance company 9 is wasted before being received by the remote monitoring device 2 in charge of the desired elevator. a lot of time
[0038] On the other hand, although the method of enabling local communication between multiple remote monitoring devices 2 improves the above-mentioned problems, there is a problem of reliability in communication between multiple remote monitoring devices 2A, 2B, and 2C.

no. 1 Embodiment

[0070] figure 1 Shown is the block diagram of the first embodiment of the remote monitoring device of the present invention, figure 2 for figure 1 Block diagram of the power supply section of the remote monitoring device, image 3 for figure 1 The block diagram of the walkie-talkie power supply circuit of the remote monitoring device, Figure 4 for figure 1 Block diagram of the digital circuit section of the remote monitoring device.

[0071] figure 1 The remote monitoring device 2 with Figure 22 Based on the remote monitoring device 2, the same symbols represent the same components. exist figure 1 In the remote monitoring device 2 of , in order to control the load circuit of the battery 26 of the walkie-talkie, a power supply unit 27A having a power supply circuit 34 for the walkie-talkie is provided. other parts with Figure 22 The remote monitoring device is the same.

[0072] like figure 2 As shown, in the power supply unit 27A, the structure is as fol...

no. 2 Embodiment

[0089] The second embodiment involves image 3 Delay circuit 43 is described. This delay circuit 43 is constituted by, for example, a combination of C·R (capacitance and resistance), for example, a series circuit of both. The delay circuit 43 is charged by the interphone battery 26 only under the condition that the emergency call button 6A is pressed and the electromagnetic relay 37 does not operate.

[0090] According to the signal from the digital input and output circuit 33, the electromagnetic relay 37 is in an inoperative state, and even after the emergency call button 6A is released, it can be the same as the state when the emergency call button 6A is pressed, with the delay circuit 43 as the power supply The electromagnetic relay 35 is excited for a predetermined time by the relay contact 37b, and the contact 35a is closed. The power supply state when the contact 35a is closed is the same as above.

[0091] With this power supply, the CPU 14 starts up, and the electr...

no. 3 Embodiment

[0094] Figure 8 Shown is a block diagram of an intercom power supply circuit 34 according to a third embodiment of the present invention. A voltage detection unit 42 is provided in the power supply circuit 34 of the walkie-talkie, where the output voltage value of the battery 26 of the walkie-talkie is monitored. The monitoring result is sent to the CPU 14 through the data input unit 41 . The voltage detection unit 42 is a device that detects whether the output voltage value of the battery 26 of the walkie-talkie is equal to or higher than a predetermined value, and can be constituted by a commercially available voltage detection IC.

[0095] Figure 9 shown as will Figure 8 The discharge characteristic of the walkie-talkie battery 26 is expressed as a graph of the voltage-time characteristic. Usually, when it is fully charged, it shows a value slightly higher than the rated value Vn, and then it is consumed due to the flow of discharge current, so that the voltage drops...

Abstract

A remote monitoring system for elevator has a plurality of remote monitors for individually monitoring the running states of a plurality of elevators installed in a building, transmits running state data from the remote monitoring system via a communal public telephone line to a communal monitoring center, and allows communication between interphones, provided in the carriages of the elevators, and the monitoring center via the public telephone line. Each of the plurality of remote monitors comprises a memory unit which stores incoming time data of different incoming times, the remote monitor performing incoming controls after independently determining call signals from the monitoring center, based on the incoming time data stored in the memory unit. Furthermore, a first switching unit cuts off the auxiliary power when there has been no irregularity in the monitoring information of the elevator after the operating power has been supplied for a fixed period of time from an auxiliary power instead of the main power when the main power fails; and a second switching unit is driven by power from an interphone battery, and re-injects the auxiliary power when an emergency call button has been pressed.

Description

technical field [0001] The invention relates to a remote monitoring device for an elevator. [0002] More specifically, it relates to a remote monitoring device for an elevator, which includes an auxiliary power supply that replaces the main power supply to supply working power when the main power supply fails, a walkie-talkie battery for the walkie-talkie installed in the elevator car, and monitors the operation of the elevator. The device that sends the operating status to the monitoring center of the elevator maintenance organization through the public telephone line network, and the device that can communicate between the walkie-talkie and the monitoring center by pressing the emergency call button set in the elevator car. [0003] The present invention also relates to a remote monitoring system for elevators, which has multiple sets of remote monitoring devices for respectively monitoring the operating states of a plurality of elevators installed in a building, and sends ...
