RX7, transmitting antenna CAT1, receiving antenna
The combination of RANT5 is defined as a transmitter/receiver CM.
This is the same as in FIG. 1 except that the door opening command signal is received and the stop signal for fixed position stop control and the door opening start signal are transmitted.

In addition, in Fig. 4, the door switch DS ₅ ,
The output of DS ₆ is connected to transmitters CT ₃ , CT ₄ and logic circuits.
At the same time, the reception outputs of the contact group GS ₂ and the receivers RX ₇ and RX ₈ are also applied to the logic circuit RY, from which an open signal is sent to the drive devices M ₃ and M ₄ . This is the same as in FIG. 1 except that the systems of door switches DS ₁ to _{DS 4} to receivers RX ₅ to _{RX 8} in FIG. 2 are omitted.

However, the transmitters CT ₃ and CT ₄ send out a door open command signal in response to the operation of the door switches DS ₃ and DS ₄ along with the check-in signal, and the receivers RX ₇ and RX ₈
is designed to receive a door opening start signal as well as a stop signal.

Therefore, if the front end F side is the traveling direction, the contact group of each relay that determines the rotation direction of the travel motor
Transmitter on the vehicle depending on heading information from GS ₂
CT ₃ is transmitting a check _- in signal via transmitting _antenna CTA ₁ , and vehicle detection is performed in the same manner as in _FIG . As the stop signal is transmitted, this is the receiving antenna facing the loop antennas LC ₄ to LC ₇ .
It is received by receiver RX ₇ via RANT ₅ , and fixed position stop control is performed in the same way as in FIGS. 1 and 2.

Then, when the door switch DS ₅ is operated, the transmitter CT ₃ sends out a door opening command signal together with the check-in signal, using a separate frequency or by modulating the check-in signal with a specific frequency as a carrier wave. so that they are transmitted from the transmitting antenna CTA ₁ and sent by the ground receiver R ₄ to the loop antenna LC ₄ and the relay
Received via LR ₁ .

Then, the reception output of the receiver R ₄ is given to the drive device M ₁ and the signal generator SG ₁ , and in response to the drive device M ₁ , the door HD ₁ opens and the transmitter
T ₆ sends out a door opening activation signal using the same method as in Figure 1, and relay LR ₁ and loop antenna
Transmit via LC ₅ .

However, the carrier frequency or modulation frequency of the door opening activation signal is changed depending on the side where the platforms H ₁ and H ₂ are located with respect to the traveling direction of the vehicle TN ₂ , and the signal LF indicating the left side or the signal RI indicating the right side is used.
The type is determined as follows, and the signal LF is transmitted from home _H1 .

This door open activation signal is received by the receiving antenna
Signal received by receiver RX ₇ via RANT ₅
When the signal is LF, relay LR7 operates, and when the signal is RI, relay RR7 operates, so
In home H ₁ , relay LR7 operates, and its contact information is given to logic circuit RY, which is
A judgment is made in conjunction with the traveling direction information from the contact group GS ₂ , and an opening signal for the door MD ₁ facing the platform H ₁ is sent to the drive device M ₃ , so that the door MD ₁ is opened.

Also, when vehicle TN ₂ stops at platform H ₂ ,
In response to the operation of door switch DS ₅ , a door open command signal is transmitted along with a check-in signal in the same way as described above, and this is transmitted to loop antenna LC ₇ and relay LR _2.
With the opening of _{the door HD 2 ,} a signal RI is transmitted by the transmitter T ₇ via the relay LR ₂ and the loop antenna LC ₇ , and accordingly the door MD ₂ is opened. Open.

In addition, if the rear end R side is in the traveling direction, the transmitter
CT ₄ transmits the check-in signal, transmitter CT ₃ transmits _the check-out signal, and receiver RX ₈ is activated _. is transmitted, and door HD ₂ opens, correspondingly door MD ₂ opens, while home H ₁
Then, the signal RI is transmitted and the door HD ₁ is opened, and in response, the door MD ₁ is opened.

FIG. 5 is a circuit diagram mainly consisting of the logic circuit RY, and the contact group GS ₂ that provides the traveling direction information is connected to the front end F of the vehicle TN ₂ in response to the operation of the traveling direction switch.
If the side is in the direction of travel, the polarity reversing relay of the traveling motor
When CHF operates and the rear end R side is the traveling direction, the similar polarity reversing relay CHR operates, so
When proceeding to the front end F side, the operation closing contact chf ₁ under the reversal relay CH is turned on, and the similar recovery closing contact is turned on.
chf ₂ is off and relay is off at home H ₁
In response to the operation of LR7, relay MR1 operates by turning on its operation closing contact _er71 .

On the other hand, a relay SR is provided which is driven by the output of a speed generator etc. connected to the running shaft.
This is restored in response to the stoppage of TN ₂ , and its restoration closing contact sr ₁ is turned on, so the door switch is activated.
If DS ₅ is turned on, the relay that is turned on will
The loop circuit via the operating close contact mr1 ₁ of MR1 is closed, an open signal is sent to the drive device M ₃ , and only the door MD ₁ on the platform H ₁ side is opened.

Also, in home H ₂ , depending on the operation of relay RR7,
This operation close contact rr7 ₁ turns on and the relay
MR2 operates and its operation closing contact mr2 ₁ is turned on, so in response to door switch DS ₅ being turned on, the loop circuit is closed on the premise that the recovery closing contact sr ₁ of relay SR is on. Then, a release signal is sent to the drive device _M3 , and the home
Only door MD ₂ on the H ₂ side opens.

In contrast to the above, when proceeding toward the rear end R side,
The operating closing contact chr ₁ of the reversing relay CHR is on, and the similar recovery closing contact chr ₂ is off, and in response to the operation of relay LR8 at home H ₂ , its operating closing contact er8 ₁ is turned on. relay MR2 operates,
Contact mr2 ₁ of this turns on, so if door switch DS ₆ is turned on, the drive device will turn on as described above.
An open signal is sent to M ₄ and only door MD ₂ opens.

Also, at home H ₁ , due to the operation of relay RR8,
The operation closing contact rr8 ₁ is turned on, and in response, the relay MR1 is operated and the contact mr1 ₁ is turned on. Therefore, when the door switch DS ₆ is turned on, the signal is sent to the drive device M ₃ in the same way as described above. A release signal is sent,
Only door MD ₁ opens.

Therefore, depending on the traveling direction information from contact group GS ₂ and the reception outputs of receivers RX ₇ and RX ₈ , the home
Since the doors MD ₁ and MD ₂ facing H ₁ and H ₂ are determined and an opening signal is sent accordingly, the side door where the platform does not exist is never opened, and the vehicle TN ₂ door switch DS ₅ ,
By operating DS ₆ , the door HD ₁ of platform H ₁ , H ₂ ,
Since HD ₂ is also opened for the first time, only the doors required for boarding and exiting will be opened after safety conditions are met, and safety opening control of the boarding and exiting doors will be performed.

Furthermore, transmitters CT ₃ and CT ₄ for check-in and check-out signals and receivers RX ₇ and RX ₈ for receiving stop signals are used to transmit a door opening command signal and receive a door opening start signal. Therefore, there is no need for a transmission/reception system for door opening control, and the overall configuration is greatly simplified.

Although the receiving system for ATC signals is omitted in Fig. 4, the check-in signal, check-out signal, stop signal, ATC signal, etc. have different frequencies, modulation formats, etc. in order to prevent mutual interference. In order to transmit the door open command signal together with the check-in signal and the door open start signal together with the stop signal, the transmitter
CT ₃ , CT ₄ , T ₆ , T ₇ etc. are the same as conventional ones, and a single or multiple frequency modulation signal source is added to them like signal generators SG ₁ and SG ₂ , or internally The receivers RX ₇ , RX ₈ , R ₄ , R _{5 ,} etc. may be provided with a single frequency or a combination of multiple frequencies to represent the door open command signal and the door open start signal. It is sufficient to use something equivalent to the above, and add a receiving function according to the door opening activation signal and the door opening command signal.

However, the configuration shown in FIG. 5 may be based on a highly reliable semiconductor element circuit instead of using relays.
The same effect can be obtained by using other circuits or switches that operate or operate depending on the direction of travel in place of the contact group GS ₂ . ,
Various types of multiplex transmission means can be applied as long as they can be distinguished from each other and do not interfere with the functions of the check-in signal and stop signal.

Further, when transmitting the door opening command signal, the transmission of the check-in signal may be temporarily interrupted, and the relationship between the door opening start signal and the stop signal is the same.
Various modifications are possible depending on the situation.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the originally required transmission/reception equipment for check-in signals and check-out signals, and transmission/reception equipment for fixed position stop control are used, and some functions are added to these equipment. Since the purpose can be achieved only by using insulated wheels such as rubber tires, the configuration can be simplified and the equipment cost can be reduced in various transportation systems that use insulated wheels such as rubber tires. Great effects can be obtained in security release control.
