Abstract

PURPOSE:To determine the length of a train correctly, by using a method by which a detector B is checked when the head of the train reaches a point where a detector A is provided and a method by which the detector A is checked immediately after the end of the train passes the point where the detector B is provided in a combination manner. CONSTITUTION:When a train T1 having a short composition is passing a rolling stock detector B, a light beam lb is shielded, a rolling stock detecting relay BLR is restored, and a reaction relay BLPR is operated. When the end of the train T1 has passed the detector B, the relay BLR is operated and the relay BLPR is restored. Since the operating state is maintained for a specified time period by damping characteristic, a relay LLc is operated, and the fact that the train T1 is short train is detected. Even though a short composition train T2 that follows the T1 is passing the detector B before the train T1 reaches the detector A, the short train length detecting relay LLc maintains the detection of the short composition train without the effect of the following train through a self-keeping circuit from a restoring contact point ALPR to the operating contact point LLc.

ことを目的とするものである。In railway equipment, it is often necessary to detect the length of a train. For example, if a train enters a station platform that is shorter than the length of the train and then opens the exit door, there is a risk that the passengers may fall to a place where there is no platform, or there will be an inconvenience that they will not be able to get off the train. Therefore, it is necessary to distinguish between long and short trains/car lengths, and to prevent trains that are longer than the platform length from opening the route to that platform. The object of the present invention is to automatically detect the length of the train with high precision and to prevent the above-mentioned dangers and inconveniences in advance.

の車両検出状態を調べて判定することもできる。As a method for determining whether the train length is greater than or less than a certain length, for example, two vehicle detectors A and B are placed along the running path L of the train T shown in Fig. 1(a), separated by a certain distance Lc. If detector A detects the head of the train and detector B also detects a vehicle, the train length is longer than the distance Lc, as shown in FIG. , when detector A detects the head of the train, if detector B does not detect a vehicle, it is determined that the train length is shorter than the distance Lc, Ts, as shown in Figure (C). do. Conversely, as shown in Figures (a) and (e), when detector B detects the rear of the train, detector A
The determination can also be made by checking the vehicle detection state of the vehicle.

点がある。However, it is difficult to determine which of the two methods described above, namely, the method of checking the vehicle detection state of the rear detector based on the detection of the front of the train, or the method of checking the vehicle detection state of the front detector using the detection of the rear of the train as a reference. This method has the following drawbacks.

ないためには、検知器Ａ。For example, vehicle detectors A and B are placed on both sides of the block boundary (a) of the train route shown in Figure 2 (f), or on both sides of the block boundary (b) shown in Figure 2 (9). If installed (Note: S in the figure is a block signal), the preceding train T1
and the following train T2, and the train T1, which is shorter than the distance Lc, is erroneously determined to be a train longer than the distance Lc. Figure 1(f) shows a method of checking detector B when the head of the preceding train T1 reaches the detector A point as shown in Figure 1(c), and the following train T2 has already reached the detector B point. If it has reached the distance Lc, it will be erroneously determined that the train is longer than the distance Lc. Similarly, Figure λtg) shows the method of checking detector A when the tail of the following train T2 passes the point of detector B as shown in Figure 1(e), and detects that the preceding train T is still detected. If the train does not pass through point A, it will be erroneously judged as a single train with a distance longer than Lc. In order to avoid such misjudgments, detector A must be used.

Ｂをコ列車以上が同時に進入しない区間、例えば同−閉
そく区間内に設けなければならない。B must be installed in a section where two or more trains do not enter at the same time, for example, in a block section.

しかしながら同−閉そく区間に設けたとしても無閉そく
運転時には−閉そく内にユ列車以上入ることが考えられ
るので、尚誤判定の可能性が残される。However, even if the block is installed in the same block section, during non-block operation, it is possible that more than one train will enter the block, so there is still a possibility of erroneous determination.

As shown in (e), the two methods of checking detector A immediately after the tail of the train passes the installation point of detector B are combined and the results of both methods are compared to finally determine the length of the train. By doing so, the above-mentioned drawbacks are solved, and correct judgment can be made without being restricted by the installation location of the detector.

A track circuit IT, 2T is constructed by applying rail insulation to the track circuit IT, 2T, and the track with the block section set is connected to the track where the train runs, and the block boundary (a) is sandwiched between the two points separated by a distance Lc. These are seven examples in which a light beam transmitter/receiver is installed as a vehicle detector. That is, As and BS are light transmitters, AR and BR are light receivers, and the light transmitter AS and the light receiver AR form a vehicle detector A.
This is an example in which a vehicle detector B is configured by a light transmitter BS and a light receiver BR.

応リレーＢＬＰＲの条件回路である。(Sth turn) is a detection condition circuit for the vehicle detection relay ALR in the vehicle detector A configured as shown in FIG. 9(a). The contact AL in the same figure is the contact of the light receiving relay AL (hereinafter, contacts are indicated with the same symbol as the relay to which they belong), and the contact 1T
R is a contact point of a track relay 1TR (not shown) of the track circuit 1T, and only under the condition that there is a train in the track circuit 1T, the interruption of the light beam 2a is detected, the relay ALR is restored, and the vehicle is detected. Figure (b) shows a slow-release reaction relay A.
This is a conditional circuit for LPH. Figure (C) shows the detection condition circuit of the vehicle detection relay BLR in the vehicle detector B configured as shown in Figure (b), where the contact BL is the contact of the light receiving relay BL, and the contact 2 TR is the contact of the light receiving relay BL. Track circuit 2T
This is the contact point of the track relay 2TR (not shown). In this case, under the condition that there is a train on the track circuit 2T, the light beam 4b
When the relay BLR detects that it has been interrupted for a certain amount of time (the time required for the shortest train to pass at maximum speed), the relay BLR is restored and vehicle detection is performed. Therefore, the relay BLR is required to have slow release characteristics. Figure (d) shows a conditional circuit for a reaction relay BLPR with slow release characteristics.

し、同図（ａ）の反応リレーＢＬＰＲは動作している。Next, the operating state of train length determination will be explained using FIGS. 3 to 7. When a current train passes through the installation point of the vehicle detector B and is at the position of the train Ts in Fig. 1(e), for example, the short train T in Fig. 7 (■) is on the track circuit 2T. When it is on top, orbital relay 2TR
'(not shown) has been restored. Also, while this train T1 is passing through the installation point of vehicle detector B, there is a light beam! Since the light receiving relay BL of the vehicle detector B has been cut off by this train T for more than a certain time, that is, more than the slow release time of the relay BLR, the light receiving relay BL of the vehicle detector B has been restored. Therefore, the excitation circuit of the detection relay BLR shown in FIG. S(c) is cut off, the relay BLR is restored, and the reaction relay BLPR shown in FIG. S(a) is operating.

検知する。When the tail of train T1 finishes passing the installation point of vehicle inspection device B, detection relay BLR is activated and reaction relay BLP is activated.
Although R recovers, it does not recover immediately and remains in an operating state for a certain period of time due to its slow release characteristics.In the circuit shown in Figure 6), power supply (+) → operating contact B L R-+ operating contact BLPR → Operating contact ALR → Recovery contact MLc →

Even if the light beam 7a advances from the position shown in Figure 7 to the position shown in Figure 7, the light beam 7a does not reach the installation position on the vehicle detector.
Since the reaction relay ALPR has been restored, the relay LLc (d.) Even if the reaction relay BLPR is restored and the above excitation circuit is cut off, the recovery contact ALPR → operation. The operation is self-maintained through the circuit of the contact LLc. In this way, the presence of the train T1 is detected and stored. This shows a state in which the short train T2 is passing through the installation point of the vehicle detector B, and in this case also the short train length detection relay LLc is connected to the recovery contact ALPR.
→The operating state is maintained through the self-holding circuit of operating contact LLc. In other words, detection of short trains is maintained without being affected by subsequent trains.

When train T2 is passing through the installation point of vehicle detector B and has finished passing through the installation point of vehicle detector B, the vehicle detection relay ALR in Figure S (a) is restored and the reaction relay ALPR in Figure S (b) is restored. operates, so the short train length detection relay LLc is connected to the recovery contact A.
The operation is self-maintained through the LR→operation contact LLc circuit, and the memory of short train detection is maintained. More train T
1 progresses and passes the installation point of vehicle detector A as shown in Figure 7 (■), vehicle detection relay A in Figure S (a)
The LR operates, and the reaction relay ALPR shown in FIG. 2(b) recovers, but does not recover immediately and remains in an operating state for a certain period of time. On the other hand, since the reaction relay BLPR in diagram (d) has already been restored, all the excitation circuits of the short train length detection relay LLc are cut off, and the relay LL is disconnected before the reaction relay ALPR is restored.
c is restored.

Since contact BLR in a) is open, relay LLc is restored. In other words, it returns to the initial state. On the other hand, at this time the fourth
Relay MLc that detects long trains in Figure (b) is relay LL.
C cannot operate while the vehicle detector A is in operation, and when the train T1 finishes passing the installation point of the vehicle detector A, the relay ALR operates and its recovery contact ALR is opened, so it cannot operate as well.

。As shown in Figure 7 (■), when train T1 leaves the proceeding gate and the following train 1 passes through the installation point of vehicle detector A,
) is restored, and in the circuit of Figure 4 (a), power supply (+) → recovery contact ALR → recovery contact A
LPR → Operation contact BLR → Recovery contact BLPR + Recovery contact MLc → Relay LLc → Short train length detection relay LLc is operated by the excitation circuit of the power supply (-) to detect and store train T2, and train 4 is sent to the vehicle detector. After passing the installation point, the excitation circuit is cut off and restored by the operating vehicle detection relay ALR, and it is determined that one train T2 is a short train length.

Next, let us consider the situation in Figure 4 when the preceding train T1 is a short train and the following train T2 is a long train with a set length Lc or more (as shown by the broken line extension of train 1 in Figure 7). The circuit operation will be described.

, When T2 is in the position shown in Figure 7 (b), the short train length detection relay LLc is in operation, so its recovery contact LLc is open, as shown in Figure 4 (b). ), the excitation circuit of the long train length detection relay MLc is cut off, the relay MLc does not operate, and the detection that the train T2 is a long train is not performed. Furthermore, when trains T and T2 (however, long trains) are in the position shown in Figure 7 (■), the circuit in Figure 6 (a) is not configured, as is clear from what has already been said, and the short train Long detection relay LLc
has been restored, train T1 has moved on, and train T2 is straddling the installation positions of vehicle detectors A and B as shown in Figure 7 (■), then the condition circuit of Figure 6 (b) is configured, the long train length detection relay MLc operates, and the train T2
is detected to be a long train with a set length Lc or more.

It is a figure which shows an example. Figure 7■ is essentially the same figure■
The state is the same as that in Figure 6(b), as already mentioned.
The circuit is configured to operate the long train length detection relay MLc to detect and store that the train T3 is a long train.

If the following train 1 is passing the installation point of vehicle detector B while passing through the installation point of vehicle detector B, vehicle detection relay ALR, BLR
Since the short train length detection relay LLc has also been restored, the long train length detection relay MLc continues to operate by the circuit shown in FIG. 4(b). Furthermore, as shown in Figure 7 ■, while train T3 is passing through the installation point of vehicle detector A,
When the following train T4 has passed the installation point of vehicle detector B, vehicle detection relay BLR is activated, but one vehicle detection relay ALR is still restored, so long train length detection relay MLc is still activated. Continue.

編成列車であることを検出する。However, as shown in FIG. 7 [Phase], when the train T3゜1 has passed through each installation point of the vehicle detectors A and B, both the vehicle detection relays ALR and BLR are operating. In addition, since the reaction relay BLPR in Figure S (d) has been restored, both the short train length detection relay LLc and the long train length detection relay MLc have been restored, and the train length detection relay up to that point,
The memory state will be reset. Train T4 is the preceding train -
If not, the short train length detection relay LLc would have operated when the train passed the installation point of vehicle detector B to detect that it was a short train, but the opportunity to do so would have been lost due to train T3. Become. However, when train T3 moves on and train 1 moves further and reaches the installation point of vehicle detector A as shown in Figure 7 ■, in this case train T3 in Figure 7 ■
2 (however, it is a short train), and as already mentioned, the short train length detection relay LLc operates and detects that the train T4 is a short train.
