Description

  The present invention relates to a power-supplied vehicle control ground element.

  As a terrestrial / on-vehicle message transmission means, a non-power-source vehicle control ground element is known. The non-power source type ground element itself does not have a power source, and when the vehicle approaches, it receives a power wave transmitted from the vehicle top element and operates using the received power wave as a power input.

  As this type of vehicle control ground element, a ground element that simply transmits one type of telegram (hereinafter referred to as a single telegram type ground element) and a ground element that can transmit a plurality of telegrams (hereinafter referred to as a plurality of telegrams). Telegram-type ground element) is known.

  Since the single telegram-type ground unit can only perform the simple operation of always transmitting the same telegram to the vehicle, the usable range must be limited, for example, a specific point such as a point or a sharp curve. It is used for the purpose of applying deceleration control to a vehicle passing there at a location.

  The multi-telegram type ground element is known from, for example, Patent Document 1 and Patent Document 2. In the multi-message type ground element, since the messages directed to a plurality of vehicles are transmitted at the same time, the messages directed to the vehicles other than the specific vehicle are transmitted with an invalid message.

  However, in the case of vehicle control by the ground unit, it is not clearly classified into two cases: a case where it can be sufficiently covered by the installation of a single telegram type ground unit and a case where a plurality of type telegram type ground units must be used. In some cases, control is required to be positioned between the two. For example, when a vehicle is taken out from a garage, two controls of permission and non-permission must be added. In addition, in vehicle control etc. for single wires, it is necessary to give permission for vehicle departure and disapproval.

In such a case, the single telegram-type ground unit is insufficient in function, and the multiple telegram-type ground unit is excessive in function with respect to the required function, resulting in unnecessary high costs.

  The subject of this invention is providing the ground element for vehicle control which can control transmission or a stop of a message | telegram.

  Another object of the present invention is to provide a vehicle control ground element capable of reducing the cost.

  In order to solve the above-described problem, a vehicle control ground element according to the present invention includes a power wave receiving coil, a power unit, a signal generation unit, an information transmission coil, and a switch unit. The power unit converts the power wave supplied to the power wave receiving coil into electric power. The signal generation unit receives supply of power from the power unit, and generates and outputs a transmission message. The information transmission coil transmits the transmission message supplied from the signal generation unit. The switch unit is supplied with a control signal from the outside, and opens and closes a power supply circuit from the power unit to the signal generation unit in accordance with the control signal.

  The vehicle control ground unit described above is combined with the on-board device to constitute a vehicle control device. When the vehicle upper element of the on-vehicle device is electromagnetically coupled to the power wave receiving coil of the ground element, the power wave transmitted from the vehicle upper element is received by the power wave receiving coil.

  The power unit converts the power wave supplied to the power wave receiving coil into electric power. The signal generation unit receives supply of power from the power unit, and generates and outputs a transmission message. The information transmission coil transmits a message supplied from the signal generation unit.

  The above circuit action is obtained even in a conventional single telegram type ground element, but in the present invention, a switch part is provided as a characteristic configuration. The switch unit is supplied with a control signal from the outside, and opens and closes a power supply circuit from the power unit to the signal generation unit in accordance with the control signal. By opening and closing the power supply circuit by the switch unit, the power supply circuit from the power unit to the signal generation unit is controlled, and a state of outputting a telegram and a state of not outputting a telegram can be realized.

  According to this two-stage circuit action, it is possible to control whether or not to stop the vehicle, for example, in the control of the garage portion of the vehicle or the single-line vehicle control.

  In addition, since only a simple configuration called a switch unit is used, the cost is lower than that of a ground unit that requires a plurality of telegram setting units, a memory such as a ROM, and a circuit for operating these.

  As described above, according to the present invention, it is possible to provide a vehicle control ground element that can control transmission or stop of a message.

  Other features of the present invention and the operational effects thereof will be described in more detail by way of examples with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing an example of a vehicle control device using a vehicle control ground element according to the present invention. The illustrated vehicle control device includes a track 6, a vehicle 1, and a ground element 3. The track 6 is, for example, a single line section. The vehicle 1 travels on the track 6 in the direction indicated by the arrow X. The vehicle 1 includes an on-vehicle device 22 and an on-vehicle element 21. The vehicle upper member 21 is composed of a bar antenna, for example, and always transmits the power wave S1 generated by the vehicle upper device 22 to the ground side.

  The ground unit 3 is a non-powered ground unit, and includes a power wave receiving coil 311, a power unit 321, a switch unit 303, a signal generation unit 304, and an information transmission coil 312. The power wave receiving coil 311 and the information transmitting coil 312 may or may not be integrated.

  The power wave receiving coil 311 is disposed on the ground side, and receives the power wave S1 transmitted from the vehicle upper member 21. The power unit 321 is, for example, a rectifier circuit, and has a function of converting a power wave received by the power wave receiving coil 311 into driving power P1.

  The switch unit 303 is provided in a power supply circuit from the power unit 321 to the signal generation unit 304. The switch unit 303 is supplied with a control signal S3 from the outside, and has a function of opening and closing a power supply circuit from the power unit 321 to the signal generation unit 304 in accordance with the control signal S3. The switch unit 303 may be configured using, for example, a photocoupler, a transistor circuit, or the like.

  The illustrated switch unit 303 is configured by a relay PR, and the drop contact PR1 is inserted in series in a power supply circuit from the power unit 321 to the signal generation unit 304, and is opened and closed. When the control signal S3 becomes a control condition “present” (hereinafter expressed as a logical value 1), the relay PR of the switch unit 303 is excited and the drop contact PR1 is turned off, the supply of the driving power P1 to the signal generation unit 304 is performed. Blocked.

  When the control signal S3 becomes the control condition “none” (hereinafter expressed as a logical value 0) and the relay PR of the switch unit 303 is de-energized, the drop contact PR1 falls and turns on, and the drive power P1 falls to the drop contact PR1. And is supplied to the signal generation unit 304. When the drop contact PR1 is changed to the saddle contact, the opening / closing of the contact and the logical relationship between the control signal S3 are opposite to the above.

  The control signal S3 is given from the outside as a control condition of the vehicle 1. The control contents include, for example, whether or not the vehicle 1 is stopped, whether or not the vehicle 1 is decelerated, whether or not the vehicle 1 needs to be alerted, and whether or not the in-car broadcast is performed. No. control, ON / OFF control of vehicle interior lighting, and the like can be given.

  The signal generation unit 304 has a simple structure that receives the drive power P1 from the power unit 321 and generates only one type of transmission message S2. In the figure, the signal generation unit 304 includes a telegram setting unit 341, a modulation unit 342, and an amplification unit 343. The information transmission coil 312 has a function of transmitting the transmission message S2 supplied from the signal generation unit 304.

  Next, the operation will be described. First, when the vehicle 1 approaches the ground unit 3, the power wave receiving coil 311 of the power supply unit 302 receives the power wave S <b> 1 output from the vehicle 1 and supplies the received power wave S <b> 1 to the power unit 321. The power unit 321 rectifies the voltage of the power wave S <b> 1 and converts it into drive power P <b> 1 for driving the signal generation unit 304.

  At this time, if the control signal S3 is a logical value 0, the relay PR of the switch unit 303 is de-energized, the drop contact PR1 is dropped and turned on, and the driving power P1 passes through the drop contact PR1 to be a signal generator. 304.

  When the driving power P1 is supplied, the signal generation unit 304 generates and outputs one type of transmission message S2. The transmission message S2 output from the signal generation unit 304 is transmitted to the vehicle 1 via the information transmission coil 312. Specifically, when the driving power P1 is supplied, the signal generation unit 304 sets a message by the message setting unit 341, modulates the message by the modulation unit 342, amplifies the message by the amplification unit 343, and transmits the message. A telegram S2 is generated and output.

  On the other hand, when the control signal S3 becomes a logical value 1, the relay PR of the switch unit 303 is excited, the drop contact PR1 is turned off, and the supply of the driving power P1 to the signal generation unit 304 is stopped. In this case, the message setting unit 341, the modulation unit 342, and the amplification unit 343 are in an operation stop state and do not generate the transmission message S2.

  Thus, the vehicle 1 approaching the ground unit executes predetermined control based on the transmission message S2 when receiving the transmission message S2, and does not perform predetermined control when not receiving the transmission message S2. It can be operated.

  As another control method, the vehicle 1 approaching the ground unit performs predetermined control when it does not receive the transmission message S2, and operates so as not to perform the predetermined control when it receives the transmission message S2. You can also.

  As described above, in the ground element according to the present invention, when the power wave receiving coil 311 is electromagnetically coupled to the vehicle upper element, the power wave transmitted from the vehicle upper element is received, and the power wave is transmitted to the power unit. Since the drive power P1 can be converted by the H.321, a groundless unit without power supply can be realized.

  In addition, since the driving power P1 is supplied from the power unit 321 and the transmission message S2 is generated by the signal generation unit 304 and the transmission message S2 can be transmitted by the information transmission coil 312, necessary information is transmitted to the vehicle 1. Can be given.

  Moreover, since the switch unit 303 opens and closes the power supply circuit from the power unit 321 to the signal generation unit 304 according to whether the control signal S3 supplied from the outside is a logical value 1 or a logical value 0, the signal generation unit A state in which the transmission message S2 is output from 304 and a state in which the transmission message S2 is not output can be realized.

  In addition, since it is possible to select a state in which the transmission message S2 is transmitted and a state in which the transmission message S2 is not transmitted using a simple configuration of the switch unit 303, a plurality of message setting units, a memory such as a ROM, and the like are operated. The cost can be reduced compared to a ground unit that requires a circuit or the like.

  FIG. 2 is a block diagram showing another example of the vehicle control device using the ground element according to the present invention, and shows an example used to prevent a branching device indexing accident. The illustrated vehicle control device includes a ground element 31 to 33, a vehicle 1, a track 6, branching devices 21 and 22, and direction condition relays PR71 to PR73. Reference numerals A, B, and C are garage detention lines, and a point D is an exit. The direction condition relays PR71 to 73 have contacts 21KR and 22KR linked to the branching devices 21 and 22, respectively. The ground elements 31 to 33 are shown in FIG. In the following description, when referring to the ground elements 31 to 33, reference is made to FIG.

  In FIG. 2, when the vehicle 1 travels from the point D in the direction of the garage detention lines A to C, no indexing accident occurs regardless of which of the branching devices 21 and 22 is facing.

  First, when the branching device 21 is in the localization and the branching device 22 is in the reverse position, it means that the opening direction condition from the point D to the garage indwelling line A is satisfied, so that no indexing accident occurs. When the branching device 21 is localized and the branching device 22 is in the inverted position, in the directional condition relay PR71, the contact 21KR is localized in conjunction with the branching device 21, and the contact 22KR is inverted in association with the branching device 22. . In this state, the control signal S3 has a logical value 1, the relay PR is excited, and the drop contact PR1 is turned off, so that no electronic message is transmitted. Therefore, the vehicle 1 can travel toward the garage indwelling line A without stopping.

  Next, when both the branching device 21 and the branching device 22 are in a localized position, it means that the opening direction condition from the point D to the garage indwelling line B is satisfied, so that no indexing accident occurs. At this time, in the direction condition relay PR72, the contact 21KR is localized in conjunction with the branching device 21, and the contact 22KR is also localized in association with the branching device 22. In this state, the control signal S3 has a logical value 1, the relay PR is excited, and the drop contact PR1 is turned off. Therefore, since a message is not transmitted, the vehicle 1 can travel toward the garage indwelling line B without stopping.

  Furthermore, when the branching device 21 is in the inverted position, since the opening direction condition from the point D to the garage indwelling line C is established, no indexing accident occurs. In the directional condition relay PR73, the contact 21KR is inverted in conjunction with the branching device 21. In this state, the control signal S3 has a logical value of 1, the relay PR constituting the switch unit 303 is excited, the drop contact PR1 is turned off, and no electronic message is transmitted. You can travel towards line C.

  Next, when the vehicle 1 travels from the garage detention lines A to C toward the point D, depending on the opening direction of the branching devices 21 and 22, is the state in which a message should be transmitted from the ground unit 31 to 33? Alternatively, it must be determined whether transmission should be stopped.

  For example, when the branching device 22 is in a fixed position, the route from the garage indwelling line A to the point D is not opened. In this case, since the control signal S3 output from the direction condition relay 71 becomes a logical value 0, the drop contact PR1 of the switch unit 303 of the ground unit 31 is turned on, and stop information is immediately transmitted from the ground unit 31. Stop control is immediately applied to the vehicle 1 heading from the garage detainment line A to the point D. This prevents indexing accidents.

  Next, when any of the branching device 21 and the branching device 22 is in an inverted position, the route from the garage detainment line B to the point D is not opened. In this case, since the control signal S3 output from the direction condition relay 72 becomes a logical value 0, the drop contact PR1 of the switch unit 303 of the ground element 32 is turned on, and stop information is immediately transmitted from the ground element 32, Stop control is immediately applied to the vehicle 1 heading from the garage detainment line B to the point D. This prevents indexing accidents.

  Furthermore, when the branching device 21 is in a fixed position, the route from the garage detention line C to the point D is not opened. In this case, since the control signal S3 output from the direction condition relay 73 becomes a logical value 0, the drop contact PR1 of the switch unit 303 of the ground element 33 is turned on, and stop information is immediately transmitted from the ground element 33, Stop control is immediately applied to the vehicle 1 heading from the garage detention line C to the point D. This prevents indexing accidents.

  Although the present invention has been described with reference to the embodiment, the present invention is not limited to this embodiment, and it goes without saying that various modifications and changes can be made within the scope of the claims.

It is a block diagram which shows an example of the vehicle control apparatus using the ground element concerning this invention. It is a block diagram which shows another Example of the vehicle control apparatus which concerns on this invention.
