Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

The main system in the present invention is a system in which operating power for a multi-channel multiplexer (MUX) using DC 12V as an operating power supply is supplied through a power supply terminal.

The call line between each module of the main system may be connected through a call terminal, and the call line may be connected to a call line, which is a general telephone line network (PSTN).

In addition, it is possible to read the status of 24V signal and detect whether there is a failure of the input through the sensing terminal, and the multiplexer and the telephone are connected through the telephone terminal, and also the change of variables such as the phone number and the number of the main phone and the disaster prevention room It includes an RS232C communication terminal for interfacing with a telephone. The main system also includes a power switch for a 16-channel multiplexer, a telephone selection switch, a call switch for external calling on the main phone side, and a call switch for emergency calling on the own side.

Therefore, the RS232C communication is possible between the emergency call of the elevator and the telephone of the disaster prevention room and the system.

The schematic configuration of the emergency call and call system of the elevator according to the present invention will be described with reference to FIG.

First, the power supply unit 12 for supplying power for controlling the system, the input unit 14 for changing various variables such as the phone number and the number of the main phone, and also the emergency room interphone (not shown) and the emergency caller in the elevator The signal detecting unit 22 detects the connection state of the (not shown), and operates by receiving power from the power supply unit 12, and stores the information input from the input unit 14 in the memory 24. A control unit 20 that receives the detection signal from the signal detection unit 22 and performs control of the handset IC 30, and a signal for connection with the trunk line 40 according to the control signal of the control unit 20. It consists of a handset IC (30) for generating a, and the tone detection unit 50 for detecting the tone signal from the trunk line 40 and inputs to the control unit (20).

The handset IC 30 integrates a plurality of devices for handset or sign language.

The memory 24 stores a plurality of telephone numbers and input data sequentially at predetermined addresses. Therefore, the memory 24 may store a telephone number of a customer support unit or an A / S agent, and the like, by sequentially accessing the control signal of the control unit 20 to perform read / write.

Hereinafter, the operation of the emergency call and call system of the elevator according to the present invention configured as described above will be described with reference to a schematic flowchart as shown in FIG. 3.

First, if an emergency occurs during operation of the elevator, if the passenger turns on the emergency call button in the cage in step 110, the system detects the call signal in step 112 and determines whether the intercom of the disaster prevention room and the emergency pager are connected. . At this time, when the passenger is connected to the intercom, the passenger may notify the emergency by attempting a call.

If the intercom and emergency pager of the disaster prevention room are not connected, the system determines that the management personnel in the emergency room are absent, and in step 120, the call signal from the emergency caller is a predetermined time (T ≥ 15 seconds) or a predetermined number of times ( N≥5 times (setting value can be changed) It is judged whether the trigger is repeatedly triggered, and as a result of the determination, when the trigger is longer than the predetermined time and the predetermined number of times, in step 122, the parent is automatically set to system memory (M = M1 + 1, M1 = memory address) sequentially accesses the phone numbers stored in the first memory address and dials them first. Thereafter, in step 124, it is determined whether the corresponding phone number is connected, and if the determined phone number is connected, the passenger may try to speak with the other party of the corresponding phone number to notify the emergency.

If there is no response from the other party or if a busy signal is detected and it is determined that it is not connected to the other party of the corresponding phone number, the system controls the memory address M1 at step 130 under the control of the control unit 20. A control signal is generated to increase one by one, and the process is repeated in step 122. The telephone numbers stored in the system memory (M = M1 + 1, M1 = memory address) are automatically accessed and dialed sequentially. Repeat the process.

On the other hand, when a response is made in the disaster prevention room or the machine room, the dialing is automatically canceled.

As described above, according to the emergency call and call system of the elevator according to the present invention, the emergency call of the elevator and the main system of the telephone of the disaster prevention room are connected to the interface for RS232C communication with the emergency caller and the emergency room telephone through the main system.
