This relates to facilitating the installation of the device.

自動列車停止装置として変周式のATS−S形が特許文献1に示すように従来から広く使用されている。このATS−S形は、図4に示すように、車上子31のコイルを帰還回路とした増幅器32により常時発振周波数fの発振回路を設け、走行している列車の車上子31がL−C共振回路からなる地上子33の上を通るときに、発振回路の常時発振周波数fが地上子33に設定された共振周波数f1に変周することを利用して周波数選別回路34から地上子検出情報を出力している。   As shown in Patent Document 1, a variable speed ATS-S type has been widely used as an automatic train stop device. As shown in FIG. 4, this ATS-S type is provided with an oscillation circuit having a constant oscillation frequency f by an amplifier 32 having a coil of the vehicle upper 31 as a feedback circuit. The frequency selection circuit 34 uses the fact that the oscillation frequency f of the oscillation circuit changes to the resonance frequency f1 set in the ground element 33 when passing over the ground element 33 composed of the -C resonance circuit. The detection information is output.

また、高品質の多情報を高速度で伝達するATS−P形も使用されている。このATS−P形の車上子35は、図5に示すように、O字状に形成された情報波送受信用コイル36と8字状に形成された電力波送信用コイル37を有し、電力波送信部38から入力トランス39を介して出力される電力波を電力波送信用コイル37から地上の無電源地上子に送信するとともに情報制御部40から入力トランス41を介して出力される情報波を情報波送受信用コイル36から無電源地上子に送信する。無電源地上子は送られた電力波をエネルギー源として情報波を返送し、返送された情報波を情報波送受信用コイルで受信して出力トランス42を介して情報制御部40に送り、車上と地上で情報を伝達する。

Japanese Patent No. 2998601

前記変周式のATS−S形の車上子31は、外部のノイズによって固有の発振周波数fが変動し易く、列車にATS−S形車上装置とATS−P形車上装置の両方を設けた場合、ATS−S形車上装置はATS−P形車上装置で使用している電力波並びに情報波の影響を受け易かった。このため列車にATS−S形車上装置とATS−P形車上装置の両方を設ける場合、図6(a)の平面配置図に示すように、ATS−P形車上子35のコイル中心に対してATS−S形車上子31のコイル中心を列車の進行方向に対して左側に一定距離L1例えば210mmだけ偏移させ、かつ、図6(b)の側面配置図に示すように、ATS−P形車上子35のコイル中心に対してATS−S形車上子31のコイル中心を列車の進行方向に対して干渉が生じない一定距離L2例えば1000mm偏移させる必要があり、ATS−S形車上子31とATS−P形車上子35を個々に設置する必要があり、ATS−S形車上子31とATS−P形車上子35の設置は容易でなかった。   The variable-speed ATS-S type vehicle upper 31 has a characteristic oscillation frequency f that is likely to fluctuate due to external noise, so that both the ATS-S type on-vehicle device and the ATS-P type on-vehicle device can be used on the train. When provided, the ATS-S type on-board device was easily affected by the power wave and information wave used in the ATS-P type on-board device. For this reason, when both the ATS-S type on-board device and the ATS-P type on-vehicle device are provided on the train, as shown in the plan layout view of FIG. In contrast, the coil center of the ATS-S-type vehicle upper arm 31 is shifted to the left by a certain distance L1, for example, 210 mm with respect to the traveling direction of the train, and as shown in the side view of FIG. It is necessary to shift the coil center of the ATS-S-type vehicle upper arm 31 from the coil center of the ATS-P-type vehicle upper arm 35 by a predetermined distance L2 that does not cause interference with the traveling direction of the train, for example, 1000 mm. The S-type vehicle upper 31 and the ATS-P-type vehicle upper 35 need to be individually installed, and the ATS-S-type vehicle upper 31 and the ATS-P-type vehicle upper 35 are not easily installed.

この発明は、このような短所を改善し、外部ノイズの影響を受けないとともにATS−P形車上装置からの干渉を受けないATS−S形車上装置の車上子とATS−P形車上装置の車上子を一体化して列車に設置できるATS車上子を提供することを目的とするものである。 The present invention improves such disadvantages, and is not affected by external noise and is not subject to interference from the ATS-P on-vehicle device, and the ATS-S on-vehicle device and the ATS-P type vehicle. It is an object of the present invention to provide an ATS vehicle upper element that can be installed on a train by integrating the upper element of the upper apparatus .

この発明のATS車上子は、地上子を検出するための送信信号をATS−S形車上子に出力し、前記ATS−S形車上子から入力した受信信号と送信している信号とを同期させた状態の同期検波と、入力した受信信号と送信している信号の位相を90度ずらした信号との直交検波の2成分を使用して地上子検出情報を出力するATS−S形車上装置のATS−S形車上子をATS−P形車上装置の車上子と1つにまとめて一体化したことを特徴とする。The ATS vehicle upper element according to the present invention outputs a transmission signal for detecting a ground element to the ATS-S type vehicle upper element, and a received signal input from the ATS-S type vehicle upper element and a transmitted signal; ATS-S type that outputs ground detection information using two components of quadrature detection of the synchronous detection in a state in which the received signal and the phase of the received signal are shifted by 90 degrees The ATS-S type vehicle upper of the on-board device is integrated with the vehicle upper of the ATS-P type on-vehicle device.

この発明のATS−S形車上装置は、地上子を検出するのに、ATS−S形車上子から入力した受信信号と送信している信号とを同期させた状態の同期検波と、入力した受信信号と送信している信号の位相を90度ずらした信号との直交検波の2成分を使用することにより、外部からのノイズやATS−P形車上装置で使用している電力波並びに情報波の影響を大幅に低減することができるとともに地上子の周波数やQ値の相違によって受信信号の位相がずれることがあった場合に対処することができる。   In the ATS-S type on-board device of the present invention, in order to detect the ground element, synchronous detection in a state where the received signal input from the ATS-S type on-board element and the transmitted signal are synchronized, and the input By using two components of quadrature detection of a received signal and a signal whose phase of the signal being transmitted is shifted by 90 degrees, noise from the outside, power waves used in the ATS-P type on-vehicle device, The influence of the information wave can be greatly reduced, and it is possible to cope with the case where the phase of the received signal is shifted due to the difference in the frequency or Q value of the ground element.

また、地上子を検出するのに、同期検波と直交検波の2成分を使用することにより、ATS−S形車上装置における信号の送受信の効率をあげることができ、地上子検出用信号の出力レベルを抑えて消費電力を低減することができる。   Further, by using two components of synchronous detection and quadrature detection to detect the ground element, it is possible to increase the efficiency of signal transmission / reception in the ATS-S type on-board device, and to output the ground element detection signal. Power consumption can be reduced by suppressing the level.

さらに、同期検波と直交検波の2成分を使用したATS−S形車上装置はATS−P形車上装置で使用している電力波等の影響を受けにくいとともに、出力する信号レベルの高調波成分が低く、ATS−P形車上装置に対して影響を与えないことから、ATS−S形車上子をATS−P形車上装置の車上子と1つにまとめて一体化でき、列車に対して容易に設置することができる。   Furthermore, the ATS-S type on-board device using two components of synchronous detection and quadrature detection is not easily affected by the power wave etc. used in the ATS-P type on-board device, and the output signal level harmonics. Since the components are low and do not affect the ATS-P type on-board device, the ATS-S type on-board device can be integrated with the ATS-P type on-board device at the same time. It can be installed easily on the train.

また、ATS−S形車上子とATS−P形車上子を1つにまとめることにより、列車の先頭に車上子をまとめて設置することができ、ATS−P形及びATS−S形の即時停止用地上子の設置位置をずらす必要がなく、列車の誤出発等を有効に防止することができる。   Further, by combining the ATS-S type upper and the ATS-P type upper ones, it is possible to install the upper ones at the head of the train. The ATS-P type and the ATS-S type Therefore, it is not necessary to shift the installation position of the immediate stop ground element, and it is possible to effectively prevent the train from starting erroneously.

このATS−S地上子検出部3は送信部8と受信部9を有する。送信部8は発振回路10と地上子検出波生成部11とD/A変換部12とローパスフィルタ13及び増幅部14を有し、受信部9は減衰器15と第1の信号処理部16と第2の信号処理部17及び検出判定部18を有する。第1の信号処理部16は、受信信号と地上子検出波生成部11で生成した送信信号を乗算する乗算部19とフィルタ20及びA/D変換部21を有し、第2の信号処理部17は、地上子検出波生成部11で生成した送信信号を入力して位相を90度ずらした信号を出力する信号遅延部22と、受信信号と信号遅延部22から出力する送信信号の位相を90度ずらした信号を乗算する乗算部23とフィルタ24及びA/D変換部25を有する。   The ATS-S ground element detection unit 3 includes a transmission unit 8 and a reception unit 9. The transmission unit 8 includes an oscillation circuit 10, a ground element detection wave generation unit 11, a D / A conversion unit 12, a low-pass filter 13 and an amplification unit 14, and the reception unit 9 includes an attenuator 15, a first signal processing unit 16, and the like. A second signal processing unit 17 and a detection determination unit 18 are included. The first signal processing unit 16 includes a multiplication unit 19 that multiplies the reception signal and the transmission signal generated by the ground wave detection wave generation unit 11, a filter 20, and an A / D conversion unit 21. The second signal processing unit 17 is a signal delay unit 22 that receives the transmission signal generated by the ground wave detection wave generation unit 11 and outputs a signal whose phase is shifted by 90 degrees; and the phase of the reception signal and the transmission signal output from the signal delay unit 22 A multiplication unit 23 for multiplying signals shifted by 90 degrees, a filter 24, and an A / D conversion unit 25 are provided.

このATS−S形車上装置1は、ATS−S地上子検出部3の送信部8の発振回路10から常時出力される所定の周波数の信号により地上子検出波生成部11で地上子を検出する送信信号を生成する。この生成した送信信号をD/A変換部12でアナログ信号に変換し、ローパスフィルタ13で不要な周波数成分を除去して増幅部14で増幅して送信トランス4を介してATS−S形車上子2の送信コイル6に出力している。   In this ATS-S type on-vehicle apparatus 1, a ground element is detected by a ground element detection wave generator 11 based on a signal of a predetermined frequency that is always output from the oscillation circuit 10 of the transmitter 8 of the ATS-S ground element detector 3. A transmission signal to be generated is generated. The generated transmission signal is converted into an analog signal by the D / A converter 12, unnecessary frequency components are removed by the low-pass filter 13, amplified by the amplifier 14, and then transmitted through the transmission transformer 4 on the ATS-S type vehicle. It is output to the transmission coil 6 of the child 2.

ATS−S地上子検出部3の受信部9はATS−S形車上子2の受信コイル7からの受信信号を入力トランス5を介して入力し、入力した受信信号を減衰器15で減衰させて第1の信号処理部16と第2の信号処理部17に送る。第1の信号処理部16は送られた受信信号と送信部8の地上子検出波生成部11で生成した送信信号とを乗算部19で乗算し、その直流成分をフィルタ20で抽出し、外部ノイズ等による他の信号周波数成分を除去してA/D変換部21でデジタル信号に変換して検出判定部18に出力する。第2の信号処理部17は送られた受信信号と信号遅延部22から出力する送信信号の位相を90度ずらした信号とを乗算部23で乗算し、その直流成分をフィルタ24で抽出してA/D変換部25でデジタル信号に変換して検出判定部18に出力する。検出判定部18は第1の信号処理部16と第2の信号処理部17から入力した信号により地上子検出情報を出力する。   The receiving unit 9 of the ATS-S ground unit detecting unit 3 inputs the received signal from the receiving coil 7 of the ATS-S type vehicle upper unit 2 through the input transformer 5, and attenuates the received signal received by the attenuator 15. To the first signal processing unit 16 and the second signal processing unit 17.

このように地上子を検出するのに、ATS−S形車上子2から入力した受信信号と送信している信号とを同期させた状態の同期検波と、入力した受信信号と送信している信号の位相を90度ずらした信号との直交検波の2成分を使用することにより、外部からのノイズやATS−P形車上装置で使用している電力波並びに情報波の影響を大幅に低減することができるとともに地上子の周波数やQ値の相違によって受信信号の位相がずれることがあった場合に対処することができる。   In order to detect the ground element in this way, synchronous detection in a state in which the received signal input from the ATS-S type vehicle upper element 2 and the transmitted signal are synchronized, and the input received signal are transmitted. By using two components of quadrature detection with a signal whose signal phase is shifted by 90 degrees, the influence of external noise and power waves and information waves used in ATS-P on-board equipment is greatly reduced. In addition, it is possible to cope with a case where the phase of the received signal is shifted due to a difference in the frequency or Q value of the ground unit.
