者が軌道を巡回して点検している。[Prior Art] Conventionally, a railroad track is divided into a plurality of sections, a weak current is applied to each section, and the presence or absence of an abnormality is detected from a change in the current. Then, the change of the current is inspected by a maintenance person who goes around the track.
［発明が解決しようとする課題］ しかしながら軌道回路は広範囲な地域に分散して機器が
設置されているので、従来の手法では点検工数が膨大な
ものとなり、非常の経済性が悪いものであった。[Problems to be Solved by the Invention] However, since track circuits have devices installed in a wide area distributed over a wide area, the conventional method requires enormous inspection man-hours and is extremely economically inefficient. .

対応してその抵抗値が変化するようになっている。[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 1 and 1 2 are track circuits whose both ends are insulated. A power supply 2 is connected to one end of this track circuit.
DC current is supplied to the track circuit from the
It is supposed to flow into. 4 is an annular iron core provided in a state where the current passage penetrates, a gap is provided in a part of the annular iron core, and the annular iron core is penetrated through the gap to thereby cut the current passage,
The magnetic field generated by the line current is picked up. 4 1 and 4 2 are Hall elements, the resistance value of which changes according to the value of the magnetic field.

レベルは基準レベル発生器８によって発生される基準レ
ベルと比較される。Therefore, the direct current flowing in the track circuit magnetizes the annular iron core, and the Hall element 4 exhibits a resistance value according to the magnetic field,
This resistance value is an analog value corresponding to the line current. Since the detected resistance value is transmitted as it is to the transmission device 6 of the central office via the transmission device 5, the state of the track circuit can be known on the side of the central device. The value detected by the transmission device 6 is compared by the comparator 7, and the reference level at this time is compared with the reference level generated by the reference level generator 8.

われる。When the transmitted value deviates from the reference level by a predetermined value or more, the comparator 7 generates an output signal and supplies a signal indicating an abnormality to an external device (not shown). Further, the signal detected by the transmission device 6 is supplied to the statistical device 9 so that long-term statistics can be obtained and reference materials for maintenance can be obtained. The reference level is a value that changes depending on the weather and season, and is not always a constant value. Therefore, the reference level generator 8 is based on the signals from the fine rain gauge 10 that outputs information signals such as temperature, atmospheric pressure, and rainfall, and the clock 11 that generates a seasonal signal, and the reference level signal most suitable for the condition at that time. To occur. Therefore, the determination by the comparator 7 is performed in the optimum state.
なお、図に記載した軌道回路は１回路であるが現実の軌
道回路は、軌道を複数の区間に区切り、それぞれの軌道

理できる。It should be noted that the track circuit shown in the figure is one circuit, but an actual track circuit divides the track into a plurality of sections and transmits signals from the track circuits to the transmission device 6. Therefore, the central office can manage all track circuits at one place.
［発明の効果］ 以上説明したようにこの発明は、軌道回路の状態を中央

もに、迅速な監視ができるという効果を有する。As described above, according to the present invention, the state of the track circuit is transmitted to the central office and compared therewith with the reference level corrected according to the conditions such as weather and season. However, it has the effect that it can be easily detected on the central side and the economy is improved, and that it can be quickly monitored.
