[Example] Hereinafter, details of the present invention will be explained with reference to FIG. 3 and subsequent figures showing an example.

FIG. 3 is a configuration diagram of the ground side, and FIG. 4 is a configuration diagram of the vehicle side. In FIG. 3, the loop antennas LC ₈ to LC ₁₁ in FIG. Small loop antennas LC _{12 to} LC ₁₅ are installed just in front of platforms H ₁ and H ₂ , each corresponding to the leading position of the stopped vehicle TN _{2 .} device T ₆ , T ₇ and receiver
R ₄ and R ₅ are provided. In addition, in FIG. 3, a set of transmitter T6, receiver R4, and signal generator SG1 is referred to as transmitter/receiver CH1, transmitter T7, and receiver R.

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 door opening activation signal is 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.
RY, and the reception outputs of the contact group GS ₂ and receivers RX ₇ and RX ₈ are also given 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 and 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 activation 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
The CT ₃ is transmitting a check-in signal via the transmitting antenna CTA ₁ , and vehicle detection is performed in the same manner as in FIG.

Therefore, when the vehicle TN ₂ is manually stopped at a predetermined position on the platform H ₁ and the door switch DS ₅ is operated, the transmitter CT ₃ emits a check-in signal together with a check-in signal or a check-in signal on a separate frequency. In order to send the door open command signal by modulating the signal with a specific frequency as a carrier wave, these are connected to the transmitting antenna.
It is transmitted from CTA ₁ and received by receiver R ₄ on the ground via loop antenna LC ₁₁ and relay 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

However, the carrier frequency or modulation wave number of the door opening activation signal is changed depending on the side where 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 changed.
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 is activated, and when the signal is RI, relay RR7 is activated, so relay LR7 is activated at home _H1 , and its contact information is given to the logic circuit RY. circuitry
makes a judgment together with the traveling direction information from the contact group GS ₂ , and sends an opening signal for the door MD _{1 facing the platform H 1 to} the drive device M ₃ , so that the door MD ₁ opens.

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 ₁₄ and relay LR _2.
With the opening of the door HD ₂ , the signal RI is transmitted by the transmitter T ₇ via the relay LR ₂ and the loop antenna LC ₁₄ , 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, use the polarity reversing relay CHF.
Operation closing contact CHF ₁ is on, similar recovery closing contact
chf ₂ is off and relay is off at home H ₁
In response to the operation of LR7, relay MR1 is operated by turning on its operation closing contact _lr71 .

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 operation closing contact mr1 ₁ of MR1 is closed, an opening signal is sent to the drive device M ₃ , and only the door MD ₁ on the platform H ₁ side is opened.

In addition, at home _H2 , in response to the operation of relay RR7, its operation closing contact rr7 ₁ turns on, relay MR2 operates, and its operation closing contact mr2 ₁
In order to turn on the door switch DS ₅ , the loop circuit is closed on the premise that the recovery closing contact sr ₁ of the relay SR is on, and this time, the loop circuit is closed for the drive device M ₃ . A release signal is sent,
Only door MD ₂ on platform 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 lr 8 ₁ is turned on. relay MR2 operates and its contact mr2 ₁ turns on, so when door switch DS ₆ is turned on, an opening signal is sent to drive device M ₄ in the same way as described above, and only door MD ₂ is opened. do.

In addition, in platform _H1 , the operation of relay RR8 turns on its operation/closing contact _rr81 , and in response, relay MR1 operates and turns on contact _mr11 , so door switch _DS6 is turned on. For example, in the same manner as described above, an opening signal is sent to the drive device _M3 , and only the door _MD1 is opened.

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.

Also, transmitters CT ₃ and CT ₄ for check-in and check-out signals, and receivers
Since RX ₇ and RX ₈ transmit the door open command signal and receive the door open start signal,
A transmitting system for door opening control is no longer required, and the receiving system is reduced to 1/2 of that in Fig. 1, greatly simplifying the overall configuration.

Although the reception system for ATC signals is omitted in Fig. 4, check-in signals, check-out signals, ATC signals, etc. are separated by frequency or modulation format to prevent mutual interference. In order to transmit the door opening command signal together with the check-in signal, and to transmit the door opening start signal, the transmitters CT ₃ , CT ₄ , T ₆ , T ₇ may be used.
etc. are used, and a single or multiple frequency modulation signal source is connected to the signal generator _SG1 , etc.
The receiver RX ₇ may be added to the SG ₂ or housed therein, and may be used to express the door opening command signal and the door opening starting signal using a single frequency or a combination of multiple frequencies.
For RX ₈ , R ₄ , R ₅ , etc., use the same ones as before,
What is necessary is to 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 achieved by using other circuits or switches that operate or operate depending on the direction of travel in place of the contact group GS ₂ , and the check-in signal, door open command signal, and door open start signal are mutually exclusive. Various mass transmission means can be applied as long as they can be distinguished and do not interfere with the function as a check-in signal.

Furthermore, when transmitting the door open command signal, the transmission of the check-in signal may be temporarily interrupted, and various modifications can be made depending on the situation.
