Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote monitoring device that monitors abnormalities in a building, including elevator failures, at a management center remote from the building, using a telephone line. This invention relates to improvements to a circuit that notifies the management center of a building abnormality that occurs during a call with the center.

When an elevator malfunctions, passengers may be trapped inside the car, resulting in a so-called trapped situation. At this time, in order to alleviate passengers' anxiety, an emergency button was installed inside the car, and an intercom was installed as an emergency handset.
In many cases, an emergency call device is installed that allows communication between the car and the control center by automatically dialing the control center when the emergency button is pressed.

In this case, the emergency button may also be a button on an intercom called a breath-talk system, but the reporting device is a building-side device that automatically dials when the emergency button is pressed and enables mutual communication. The device on the management center side is called the receiving device.

On the other hand, when the above management center monitors building abnormalities such as fire, gas leaks, intrusions, etc., the control center ([lj
A remote monitoring device is used that automatically dials K and sends a signal indicating the nature of the abnormality.

Although there is a difference between this remote monitoring device and the above-mentioned emergency notification device in that one is a sensor and the other is an emergency button or intercom, the devices on the sending and receiving sides have similar configurations, so recently, these devices have been Devices that perform simultaneous monitoring have come into use. In this specification, this device will be referred to as a remote monitoring device, of which the device on the building side will be referred to as the a-information device, and the device on the management center side will be referred to as the receiving device.

By the way, this type of remote monitoring device is required to handle elevator malfunctions and building abnormalities in the shortest possible time, so although the notification is made immediately,
When a building abnormality occurs following an elevator failure, notification of the latter may be delayed.

In other words, since it takes only a short time to deal with a building abnormality, even if an elevator failure occurs following a building abnormality, there is no problem in immediately reporting it.However, in the past, elevator When a call is being made between the car and the control center at the time of a breakdown, even if an abnormality occurs in the building, the abnormality is reported as soon as the call is terminated.As a result, long calls are There was a problem that if this was done, reporting of abnormalities in the building would be delayed.

The present invention has been made in order to eliminate the drawbacks of the conventional systems described above, and is a remote control system that can quickly report abnormalities in the building that occur following an elevator failure without interfering with communication between the elevator car and the control center. The purpose is to provide monitoring equipment.

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

), an abnormal signal receiving section (252) that receives a signal corresponding to an abnormality in the building, and a network control section (251), and also controls the signals of the specific signal receiving section (253) and the abnormal signal receiving section (254). The control section (255) receives the information and controls the changeover switch (252) and the display section (4). The common terminal of the changeover switch (252) is connected to the network control unit (251), one changeover terminal (a) is connected to the induction coil (c) and the specific signal reception unit (253), and the other changeover terminal (b) is connected to the induction coil (c) and the specific signal reception unit (253). are respectively connected to the abnormal signal receiving section (254).

By the way, this remote monitoring device includes a receiving section on the building (1) side and an oscillating section on the management center (2) side, but these are omitted here because they are not directly related.

The operation of the remote monitoring device configured as described above will be explained starting from a situation where an elevator is stuck and a call is being made between the elevator car and the control center (2) via the intercoms αυ and Cυ, respectively.

First, the changeover switch (152) on the building (1) side is connected to the terminal (
a) Attach the changeover switch (25) on the management center (2) side to a.
2) are also respectively switched to the terminal (a) side, and the switch of the telephone office (3) is switched to the network control unit (151) and (251).
are connected.

Here, when the fire detector αQ is activated, this ON operation signal is applied to the control unit (155)K.

In response to this, the control unit (155) controls the specific signal transmitting unit (1
53), a specific signal of 8 KHz is superimposed on the voice during the call. The transmission time of this specific signal is, for example, about 0.1 to 0.5 (sec), which is long enough to distinguish between voice and specific signal and does not interfere with communication.After transmitting this specific signal, the control The section (155) switches the selector switch (152) to the terminal () side, and shifts to a system for transmitting a signal indicating that a fire has occurred from the abnormal signal transmitting section (154).

On the other hand, in the receiving device, a specific signal superimposed on audio is detected by a specific signal receiving section (253), and the detected signal is applied to a control section (255). At this time, the control unit (255)
A switching command is output from the switch to the changeover switch (252), and the changeover switch (252) is connected to the terminal (6) side.

Next, the control unit (155) on the building side transmits a special alarm signal, and then controls the abnormal signal transmitting unit (154) after a pause of about 0.1 (Sec). As a result, a signal indicating that a fire has occurred is transmitted to the abnormal signal reception @ (254) on the management center (2) side, and the control unit (255) receives this and displays the fact on the display unit (c). .

The time required for this is about 0.1 (sac) at most, and the control section (155) on the building (1) side controls the changeover switch (152) and the control section on the management center (2) side. Part (2
55) returns the changeover switch (252) to the respective illustrated states.

Such an operation, that is, the operation of superimposing a specific signal on the voice during a call, sending out an abnormal signal with (), and then returning the changeover switches (151,) and (251)
(sec), the fire can be immediately reported without virtually interrupting the calls of the passengers in the car, and the control center can respond quickly. .

In addition, the emergency button θ on the building (1) side is connected to the intercom (Il).
The same effect as described above can be achieved by using a detector that detects that the elevator is out of order.

In addition, in the above embodiment, a specific signal of 1.8 CKHz) is
, 1 to 0.5 (8elC), the f1% signal wMa is superimposed, but this specific signal may be intermittent or the frequency may be changed every time it is intermittent. .

Furthermore, it goes without saying that the display section (261) is not limited to one that simply performs a display operation, but may also be a buzzer or a combination of these.

As is clear from the above explanation, according to the remote monitoring device of the present invention, even if an abnormality occurs in the building following an elevator failure, the abnormality will not interfere with communication between the inside of the car and the control center. can be reported quickly.
