       The present invention relates to an elevator monitoring system using an interphone power line, and more specifically, to monitor an elevator currently in operation, an interphone power line installed in each elevator by a communication line installed from an elevator machine room to an emergency room or a guard room. It relates to a lift monitoring system using an interphone power line.

      In general, an elevator device installed for vertical movement in various buildings is provided with a monitoring system for detecting an abnormal state of various devices including an elevator car currently in operation.

       In particular, the monitoring system of the elevator among the monitoring system is preferably managed together with other systems at a specific point, such as disaster prevention room, security room, management office, etc. of the building, and thus from the elevator machine room to a specific monitoring point The serial communication method is used to transmit information according to the operating state of the elevator.

       That is, the elevator machine room and a specific monitoring point are interconnected through an RS-485 communication method or Ethernet cable, which is generally used for medium and long distance control, so that data is transmitted according to the operation information of the elevator.

       However, the data transmission method using the serial communication as described above should be provided with a separate communication line, accordingly, the monitoring system of the elevator using the serial communication has a problem that a difficult and complicated separate piping must be installed, In particular, when the building is completely completed, the additional installation is very difficult and there was a problem that can not be installed.

       Therefore, the present invention has been devised to improve the conventional problems as described above, the present invention is the existing interphone power line installed between each elevator and a specific monitoring point, such as a disaster prevention room, guard room, management office of the building, etc. It is an object of the present invention to provide an elevator monitoring system using an interphone power line to solve the problem of requiring a separate pipe when installing the monitoring system by configuring the elevator monitoring system.

       Elevator monitoring system using the interphone power line according to the present invention for achieving the above object, the three wires or four-wire system for the communication between the elevator integrated monitoring room and elevator elevators such as disaster prevention room and management room An elevator monitoring system for monitoring an elevator in an elevator apparatus having an interphone line, wherein the elevator monitoring system includes a transmission / reception terminal of a monitoring panel PC provided in the integrated monitoring room and a transmission / reception terminal of a communication terminal provided in the elevator machine room. Respectively connected to the + 12V and GND lines of the interphone line wired by the three-wire (+ 12V, GND, SIGNAL) or four-wire (+ 12V, GND, SIGNAL, SIG GND) method, and the communication terminal of the elevator machine room The monitoring panel PC of the communication monitoring room is configured to transmit communication data between the + 12V lines using the + 12V and GND lines. Characterized in that a.

       Preferably, the communication terminal of the elevator machine room and the monitoring panel PC of the integrated monitoring room are each characterized in that the DC power line communication module is mounted.

       Hereinafter, the present invention configured as described above will be described in detail with reference to the accompanying drawings.

       1 is a block diagram showing a lift monitoring system using an interphone power line according to the present invention, Figure 2 is a circuit diagram showing a lift monitoring system using an interphone power line according to the present invention, interphone power line according to the present invention The elevator monitoring system using the conventional elevator elevator intercom 10 via the DC power line communication modules 32 and 42 mounted on the communication terminal 30 of the elevator machine room and the monitoring panel PC 40 of the integrated monitoring room, respectively. And integrated communication between the elevator machine room and the integrated monitoring room by using the + 12V and GND lines, the power supply line, of the interphone line A, which is wired in a three-wire or four-wire manner. By making it possible to perform.

       In other words, elevator devices installed to move vertically in various buildings have problems with elevator devices in the state of passengers in the elevators that are currently in operation. 3 lines (+ 12V, GND, SIGNAL) or 4 wires (+ 12V, GND, SIGNAL) to establish a call path between the elevator and the integrated management room such as the elevator machine room or management room as the passenger operates the elevator emergency call button in case of emergency. 12V, GND, SIGNAL, SIG GND) interphone line (A) is provided.
