FIG. 1 is a schematic block diagram showing an elevator emergency call apparatus according to a preferred embodiment of the present invention. As shown in FIG. 1, an elevator car having an emergency call button / microphone 102 and an interphone / speaker 104 is provided. (100), the machine room 110 is provided with an emergency line button 112 and the interphone 114, the call signal generated from the elevator car 100 and the machine room 110 and judges the maintenance center or a predetermined external The control room 120 is provided to connect the phone 132 and the call path setting to perform an emergency call function.

Here, the control room 120 is an input / output unit 122 for transmitting and receiving a signal transmission for the generation of the call signal from the car 100 and the machine room 110, and the generated call signal is an elevator car Selection line processing unit for performing a comparison operation with a predetermined reference voltage according to the call detection operation of the outgoing signal detection unit 126 and the outgoing signal detection unit 126 to determine which occurred in the 100 or the machine room 110. And a control unit 124 for controlling the overall operation, and an interface unit 134 for making an emergency call with the maintenance center / preset external telephone 132 according to the determination result of the control unit 124. ), And the elevator car 100 or the machine room 110 includes an interphone 123 for carrying out a call.

In addition, the elevator car 100, the machine room 110 and the control room 120 to maintain the active / inactive state according to + 12V, 0V, the first and second signal lines, and a predetermined condition, respectively, to implement an emergency call function It is interconnected by a selection line.

The selection line processor 128 is further provided with a comparator 129 for comparing the reference voltage and the signal voltage C of the selection line.

Referring to the control process according to the emergency call device of the elevator configured as described above are as follows.

First, when a predetermined call signal is generated from the elevator car 100 or the machine room 110, the call signal detection unit 126 of the control room 120 receiving the call signal via the input / output unit 122 receives the call. It is determined whether the signal is a call signal generated in the elevator car 100 or the machine room 110 (step 200; step 202).

When the call signal is generated, the signal voltage D of the first signal line transitions to + 12V among the first and second signal lines connecting the elevator 100, the machine room 110, and the control room 120 to each other. The signal voltage of the second signal line is shifted to 0V, so that the control unit 124 in the control room 120 generates a call signal in any of a plurality of machine rooms with the input voltage level of the first and second signal lines. Will be judged.

That is, if the signal voltage D of the first signal line input after driving the relay maintains 12 V, the controller 124 may determine that the generated call signal is a call signal generated from several machine rooms. Will be.

Accordingly, the machine room 110 operates any one switching means (hereinafter referred to as a relay) provided to each of a plurality of module units (not shown) connected to each unit, and then from the corresponding unit. After receiving the call signal input of is connected to the control unit 124 via the input / output unit 122 with the relay drive.

At this time, in the state where the control room 120 determines the machine room where the call signal is generated (YES in step 202), the signal voltage C of the selection line is changed from the standby state (for example, 6V) to the activation state (12V). Will be.

On the other hand, the selection line processor 128 receives 12V, which is the signal voltage C of the selection line, and supplies the selected line processor 128 to the comparator 129 provided to the selection line processor 128, while the comparator 129 The selection line processor 128 compares the reference voltage A (for example, 4.5V) with the 12V signal voltage.

At this time, it is determined whether the signal voltage (C) of the selection line is higher than the reference voltage (A), and then, according to the result, drive the corresponding relay of the machine room where the call signal is generated to establish a call path with the control room 120. Will be performed.

For example, in the comparison process, since 12 V, which is the signal voltage C of the selection line, is higher than the preset reference voltage A 4.5 V, a predetermined output signal is generated from the comparator 129, and according to the output signal, The first and second signal lines are connected to enable a call.

At this time, since the select line maintains 6 V in the standby state, unless the select line signal voltage drops below 6 V according to an error occurrence, the machine room 110 and the control room 120 always maintain the available state. do.

It is connected to the drawing (not shown in the drawing) and the call is possible.

Accordingly, as described above, if the emergency line button 112 is operated from the machine room 110 and a call is being performed between the machine room 110 and the control room 120, the signal voltage C of the selection line is 12V. Since the reference voltage B of the elevator car 100 is higher than 6.8 V, the relay drive is impossible.

That is, since the relay is not driven, the interphone / speaker 104 of the bakery vehicle 100 becomes inoperative, and the communication between the machine room 110 and the control room 120 is inside the elevator car 100. It will not be delivered to.

On the other hand, in addition to the call from the machine room 110 to the control room 120, not only can a predetermined call with the outside according to the dialing operation of the preset external phone number, and also if the phone number is in a call, the next phone number is automatically Can be dialed.

When the call signal comes from the maintenance center / preset external phone 132, the control room 120 responds to the call signal and connects the machine room interphone 114 and the external phone to make a call. .

In this case, the machine room 110 and the control room 120 should be provided with a separate signal line for making a call with the maintenance center / preset external phone 132 and a call request line in the machine room.

On the other hand, if it is not called from the machine room 110 from the determination step, the control unit 124 recognizes that the call from the elevator 100, the passenger in the elevator 100 and the control room 130 mutually performs a general call Done.

As described above, the present invention constitutes a selection line that allows the other party to select and talk to each other between the elevator car, the machine room, and the control room so that the contents of the call generated between the machine room and the control room are not transmitted to the elevator car, Passengers in the car can prevent anxiety and the like that can be caused by listening to unnecessary call content.
