BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency emergency call system for a wired / wireless hybrid type emergency call system, FIG. 3 is a block diagram of a switching circuit of a wired / wireless hybrid switching system provided in an elevator emergency calling system according to the present invention. FIG. 4 is a flowchart showing a control method of a wired / wireless hybrid emergency calling system according to the present invention. to be.

      First of all, the wired / wireless hybrid type emergency call system according to the present invention can be used in a case where emergency call apparatus 20 provided in an elevator car can not be connected to interphone line 32, , LTE, etc.) network, so that normal emergency calls can be established even when a specific communication network fails.

      For this purpose, the wired / wireless hybrid emergency call system according to the present invention comprises an emergency communication device 20 provided in an elevator car and a security or machine room connected to the emergency communication device 20 and the interphone line 32 The interphones 30 are connected to each other via a wired / wireless hybrid switch 10 having a specific structure.

      Also, the wired / wireless hybrid switching center 10 includes all the connection circuits to be connected to the wired network 40, which is a trunk line, and the wireless network 42 including 2G, 3G, LTE, Or an AS agent.

      As shown in FIGS. 2 and 3, the MCU 12 of the wired / wireless hybrid switch for selectively connecting the emergency communication device 20 in the elevator car to the interphone line 32 or the UTRAN 40 The mobile terminal 40 is configured to have functions of a PSTN and a wireless network 42, such as 2G, 3G, and LTE, such as line switching, hook detection, DTMF receiver, DTMF generator, RING generator, and call progress tone generator. And the like.

      In FIG. 2, reference numeral 14 denotes a power supply for supplying a predetermined power to the apparatus, and reference numeral 16 denotes a cross-poing switching block for connection with a wireless network.

The switching circuit operated under the control of the MCU 12 of the wired / wireless hybrid switching center 10 is connected to the emergency communication device 20 in the elevator car and is connected to an extension circuit (SLIC) (COIC) 18 and a wireless modem (2G, 3G, LTE) 19, etc., which are selectively switched with the extension connection circuit 16, and the like.

      Next, a control method of a wired / wireless hybrid type emergency emergency call system according to the present invention will be described.

      First, in a state where a wired / wireless hybrid switching system 10 having a specific function is applied to an elevator emergency call system according to the present invention, in step 100, an emergency situation in a car or an emergency communication apparatus It is judged whether there is an emergency call button operation of the emergency call button 20 or not.

      As a result, when the emergency call button from the car emergency communication device 20 is operated, the DTMF signal from the inside of the car is received by the wire / wireless hybrid switching center 10 (step 110) (10) controls the internal and external connection for the call from the emergency communication device (20) and the connection to the UTRAN (120).

      That is, when the call connection according to the emergency call button of the emergency call device 20 is an internal connection, an extension connection is made through the interphone line 32, Hooked signal for terminating the call (step 140), the call connection with the interphone 30 provided in the security room, the machine room, (Steps 142 and 144).

      In step 130, when the call connection according to the emergency call button of the emergency communication device 20 is an external connection, the wired / wireless hybrid switching center 10 switches according to whether the wireless network is normal and whether the wired network is normal (Step 130 and step 132), the emergency communication apparatus 20 can establish a call connection with the terminal of the remote service center or the AS staff through the wired network 40 or the wireless network 42 (step 134) .

      Thereafter, in step 136, it is determined whether an on-hook signal for terminating the call is generated, and control is performed so that the network connection is released (step 136).

      On the other hand, if it is determined in step 100 that there is no emergency call button operation of the emergency communication device 20 provided in the elevator car, the wireless ring signal or wired If the reception of the ring signal occurs (steps 200 and 220), the wired / wireless hybrid switch 10 will control so that the call channel inside the elevator is connected (step 230).

      At this time, if the received ring signal is a wireless ring signal, a voice call connection command is transmitted to the wireless modem 19 (step 210) to establish a call connection.

      After the extension call is connected to the elevator car according to the control of the wired / wireless hybrid switchboard 10, the extension connection is controlled according to whether an on-hook signal for terminating the call is generated 240 to step 244).

      It should be understood, however, that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.
