The platform door system has: a platform data transmitting element positioned on a platform for transmitting a platform signal; a vehicle information integrating element, positioned on a vehicle adjacent to the platform, for receiving the platform signal and a vehicle signal corresponding to a door opening or closing status of the vehicle door from the vehicle, and for transmitting a platform-vehicle integration signal; and a platform door controlling element, positioned on the platform, for receiving the platform-vehicle integration signal and for opening or closing a platform door in response to the platform-vehicle integration signal to correspond to the opening-or-closing status of the vehicle door. ## Claims ### Claim 1 A platform door system, comprising: a platform data transmitting element, positioned on a platform for transmitting a platform signal; a vehicle information integrating element, positioned on a vehicle adjacent to the platform for receiving the platform signal and a vehicle signal from the vehicle, and for transmitting a platform-vehicle integration signal in accordance with the platform signal and the vehicle signal, wherein the vehicle signal corresponds to an opening-or-closing status of a vehicle door of the vehicle; a platform door controlling element, positioned on the platform for receiving the platform-vehicle integration signal, and for opening or closing a platform door in response to the platform-vehicle integration signal to correspond to the opening-or-closing status of the vehicle door; and a vehicle door detecting element, positioned on the platform for detecting the opening-or-closing status of the vehicle door and transmitting a vehicle door opening-or-closing signal, wherein when being not capable of receiving the platform-vehicle integration signal, the platform door controlling element open or close the platform door in response to the vehicle door opening-or-closing signal. ### Claim 2 (depends on 1) The platform door system according to claim 1 wherein the vehicle door detecting element comprises an image detection unit, a sound energy detection unit, a thermal energy detection unit, or a radiant energy detection unit for detecting the opening-or-closing status of the vehicle door. ### Claim 3 (depends on 1) The platform door system according to claim 1, wherein the platform data transmitting element comprises a radio frequency transmitting unit which has an ID code of the platform. ### Claim 4 (depends on 3) The platform door system according to claim 3, wherein the platform data transmitting element is a radio frequency identification (RFID) tag. ### Claim 5 (depends on 1) The platform door system according to claim 1, wherein the vehicle information integrating element is a control logic built in an operation system of the vehicle. ### Claim 6 (depends on 1) The platform door system according to claim 1, wherein the vehicle information system further comprises: a vehicle information providing element for providing the vehicle signal; a first wireless receiving element for receiving the platform signal; and a wireless transmitting element for transmitting the platform-vehicle integration signal. ### Claim 7 (depends on 6) The platform door system according to claim 6, wherein the vehicle information providing element comprises a vehicle door opening/closing detector. ### Claim 8 (depends on 1) The platform door system according to claim 1, wherein the platform door controlling element further comprises: a second wireless receiving element for receiving the platform-vehicle integration signal; a signal processing element for determining the opening-or-closing status of the vehicle door; and a platform door opening-or-closing element for opening or closing the platform door. ### Claim 9 A control method for a platform door system, the control method comprising: providing a platform data transmitting element on a platform for transmitting a platform signal; providing a vehicle information integrating element on a vehicle adjacent to the platform for receiving the platform signal and a vehicle signal from the vehicle, and for transmitting a platform-vehicle integration signal in accordance with the platform signal and the vehicle signal, wherein the vehicle signal corresponds to an opening-or-closing status of a vehicle door of the vehicle; providing a platform door controlling element on the platform for receiving the platform-vehicle integration signal, and for opening or closing a platform door in response to the platform-vehicle integration signal to correspond to the opening-or-closing status of the vehicle door; and providing a vehicle door detecting element on the platform for detecting the opening-or-closing status of the vehicle door and transmitting a vehicle door opening-or-closing signal, wherein when being not capable of receiving the platform-vehicle integration signal, the platform door controlling element open or close the platform door in response to the vehicle door opening-or-closing signal. ### Claim 10 (depends on 9) The control method according to claim 9, wherein the platform door controlling element open or close the platform door in response to the vehicle door opening-or-closing signal after the platform data transmitting element has transmitted the platform signal for a predetermined period of time and the platform-vehicle integration signal is not received. ### Claim 11 (depends on 9) The control method according to claim 9, wherein the platform door controlling element open or close the platform door in response to the vehicle door opening-or-closing signal after the vehicle door detecting element has transmitted the vehicle door opening-or-closing signal for a predetermined period of time and the platform-vehicle integration signal is not received.
