Description

  The present invention relates to a transponder ground element that transmits control information in the form of a message using a transponder from the ground to an on-board device mounted on a train.

  In order to upgrade train control systems and perform high-density information transmission between the ground and the train, non-powered grounded elements and powered grounded elements using transponders are used. The non-powered ground unit using a transponder is supplied with operating power by the power wave transmitted from the vehicle unit when it is connected to the vehicle unit and transmits preset fixed information to the vehicle unit. . Therefore, the non-powered ground element does not require connection of a power cable or a battery, and does not require maintenance of the power cable or battery and can be easily installed.

  Patent Document 1 or Patent discloses a power-powered ground element that uses the power wave and information wave to drive the non-powered ground element to determine the position of the train and to control the opening / closing of a platform door or a movable platform fence linked to the vehicle door. It is disclosed in Document 2.

  The train position detection device disclosed in Patent Document 1 includes a power wave receiving antenna coil for short position determination and a power wave receiving antenna for just position determination along the traveling direction of the train separately from the information wave receiving antenna coil. Three power wave receiving antenna coils, a coil and an over position determination power wave receiving antenna coil, are arranged, and the reception level when the power wave transmitted from the vehicle top is received by each power wave receiving antenna coil has a threshold value. The position of the train is judged by whether or not it exceeds. That is, if only the reception level of the power wave receiving antenna coil for short position determination exceeds the threshold, it is determined that the train is in the short position, and only the reception level of the power wave reception antenna coil for just position determination exceeds the threshold. If it is determined that the train is in the just position, it is determined that the train is in the over position if only the reception level of the over position determination power wave receiving antenna coil exceeds the threshold value.

  In addition, the train position detection device disclosed in Patent Document 2 does not determine the position of the train based on whether or not the reception levels of the three power wave receiving antenna coils exceed a threshold value. Three power wave receiving antenna coils having a constant power wave reception response characteristic are arranged along the traveling direction, and the power wave reception response characteristic of the power wave reception antenna coil for short position determination and the power wave reception for just position determination Between the intersection of the power wave reception response characteristics of the antenna coil and the intersection of the power wave reception response characteristics of the power wave reception antenna coil for just position determination and the power wave reception response characteristics of the power wave reception antenna coil for over position determination Even if the reception level of the power wave transmitted by the vehicle upper and lower is physically and electrically fluctuated within the normal range of the vehicle upper Distance variation is to improve the accuracy of determining the position determination range by utilizing the extremely as compared with the position determination range small.

  In a line section that uses a new transponder to determine the position of the train and control the interlocking of the platform doors and movable platform fences linked to the vehicle doors, the target works will be constructed all at once, Except in such cases, when a door or movable platform fence is installed in a line that has already started operation, and the interlock control with the vehicle door is realized using a transponder, the construction to be covered Is often done at night after the opening of business hours, and the construction period is generally longer than that for new lines. For this reason, there are many examples where the use is partially started from a station where the installation work of ground facilities such as a platform door, a movable platform fence, a power source grounding element, a repeater, and a code processor has been completed.

In order to do so, the status of the ground unit must be notified to the on-board device. Since this information is only for the conditions for entering or advancing to the start section of use and the amount of information is small and can be realized as fixed information, conventionally, a non-powered ground element is installed in front of the section where use started and linked control is performed from the next station. When entering a section that has not started to be used from a section that has started to be used, the interlock control release information is set at the position to be combined after the departure of the last station in the section that has started using. The set no-power ground unit is installed to notify the on-board device of the entry or advance condition.

  However, in the above-mentioned correspondence, when the use start section is changed in accordance with the progress of the target construction, it is necessary to move the non-powered ground element along with the change, and the applicable line section range is large and partial. When there is a use start section, there is a problem that it is necessary to change and manage the installation position of the unpowered ground unit in a plurality of sections in accordance with the change of the use start section.

  The present invention eliminates such problems and requires an unpowered ground element that sets conditions for entering or entering an interlocking control section of a platform door or a movable platform fence linked to a train position and a vehicle door.
