That is, in the transponder disclosed herein, the interrogator transmits a microwave interrogation signal of a predetermined frequency, for example, 2.45 GHz to the transponder. The transponder generates a response signal by shifting the interrogation signal by 180 ° with a signal obtained by modulating information (data) to be responded with the first and second PN codes, and sends the response signal to the interrogator. The interrogator demodulates the received response signal using two signals obtained by shifting the interrogation signal by 90 ° to extract first and second PN codes. And the extracted PN
The data responded by the transponder is reproduced from the correlation value between the code and the PN code prepared in advance.

The device solves several problems of the track position detection type train position detection device, but still has problems. When multiple train detectors are installed close to each other, the ground transponder may respond to the adjacent ground interrogator, making it difficult to detect train presence at the branch and control the direction of train entry, and apply to railroad crossing control The problem is that you can't. Ground interrogator and ground transponder failure detection is based on transmission and reception information equipment, and on-board transponder failure is based on information from other on-board transponders and ground transponders.
Since the information is detected and processed by the control device or its higher-level device, a simple response signal still has a problem in terms of train operation management, which requires extremely high security.

Detection of no reception level occurring between the extraction of the identification information of the ground transponder 2 and the extraction of the identification information of the head-side transponder 3a or 3b determines that the train has entered. The detection of no reception level occurring between the extraction of the identification information of the front-side vehicle transponder 3a or 3b and the extraction of the identification information of the rear-side vehicle transponder 4a or 4b determines that the train is on the train. Detection of no reception level occurring between the identification information extraction of the on-board transponder 4a or 4b and the identification information extraction of the ground transponder 2 determines that the train is on the train. Detection without a reception level when the pattern differs from these patterns is determined as a failure of the interrogator or transponder.
