Definitions
- the present invention relates to a device and a method for transmission of information by a beacon so that a beacon and device, control for an information transmission device.
- These tags are passive tags and are arranged on the ground.
- Figure 1 shows a transmission device state of the art information including a equipment on board a railway vehicle and a floor installation.
- the information transmission device shown in Figure 1 includes ground installations 1, 2 and on-board equipment 3, 4 in a vehicle rail 5.
- Ground installations consist of a beacon 1 and its control device 2, the assembly being connected by means of a transmission line 7.
- the beacon 1 is fixed on crosspieces, in the axis a railway track 6.
- the on-board equipment mainly consists an antenna 3 and an evaluation unit 4.
- the evaluation unit 4 which can be a computer, is powered by its own converter and is connected to antenna 3.
- the antenna 3 is located under the rail vehicle 5, preferably at the front of it.
- the tags used in the control systems allow the transmission of information on signaling status downstream of their geographic position.
- This information is received using an antenna located under the train.
- the tag emits a series of bits in series, for example at a speed of 50 kbit / s, using equipment control electronics responsible for developing a message.
- These tags have a fixed length, which defines a region of space in which the antenna on board of a train is capable of receiving the transmitted message.
- This length of capture also called length contact, allows to transmit a certain number of bits of a message to transmit.
- a binary message is read between a control device and the train via a beacon.
- a synchronization takes place between the start of the message and the arrival of the train on the beacon and therefore at the start of the reading the tag.
- FIGS. 2A to 2C illustrate, respectively, the emission of Mn messages by means of a state tag the technique, the reading of the message by means of the antenna on-board and then the reconstruction of the message sent from message read.
- FIG. 2A shows a series of Mn messages identical emitted by a control device and transmitted via a beacon to an on-board antenna.
- the on-board antenna has a reading window predetermined which is a function of its structure.
- the binary message read by the on-board antenna may not not match the full Mn message, but match the more often to a juxtaposition of two parts complementary to two successive Mn messages.
- Figure 2B illustrates this binary message read by the on-board antenna.
- FIG. 2C illustrates the binary message reconstructed at board the train.
- the antenna capture length therefore does not allow the reception of more than one message.
- the message reconstituted on board the train is then inconsistent because composed of two parts of a first and a second messages sent with different content.
- An object of the invention is therefore a device for transmission of information by tags not presenting this disadvantage.
- Another object of the invention is a device for transmission of information by beacons allowing everything instant reconstitution of coherent messages.
- the device for message transmission contains the characteristics according to claim 1.
- the invention also relates to a beacon and a control device. for a message transmission device containing the characteristics according to claim 5.
- the invention also relates to a method of transmission of messages containing the characteristics according to claim 6.
- FIGS. 3A to 3E illustrate the delayed emission of switching C between Mn messages and Mn + 1 messages by means of a tag conforming to the principle of the invention.
- This information relating to the presence of a train allows to generate a delay in the switching C of the content messages.
- control device emits one or several additional Mn messages Mns to the beacon so as to delay switching C between messages Mn and Mn + 1 messages.
- FIG. 4 represents a block diagram of a mode preferred embodiment of a tag used in the beacon information transmission device according to the invention.
- Beacon 1 used in the transmission system information is passive equipment, i.e. having no own source of electrical energy permed.
- tag 1 is only remotely powered when a train 5 is present below the beacon 1.
- the remote supply is carried out in a known manner by coupling between the antenna 3 of the train and the beacon 1.
- the tag 1 is therefore not capable of providing energy to power a power line 7 of transmission to the control device 2.
- These superimposed signals consist of a voltage alternative corresponding to the messages sent Mn and a DC polarization of the transmission line corresponding to the information relating to the presence of a train.
- the tag 1 In the presence of a train 5, the tag 1 short-circuits the end of the transmission line from the control device 2 for direct current only.
- the control device 2 then detects a short circuit on transmission line 7 for current continuous only and infers information relating to the presence of a train 5 directly above the connected beacon 1 to the short-circuited line.
- the alternating voltage corresponding to the messages sent not being short-circuited by tag 1, the messages can be sent by the control device 2 to the antenna 3 on board by means of the beacon 1.
- the first interface 8 sensitive only to alternative signals has the function of receiving messages sent by the control device 2 and intended for be read by the on-board antenna 3.
- the second interface 9 sensitive only to current continuous has the function of short-circuiting the line of transmission 7 for direct current only.
- the information transmission method Mn comprises a first step consisting in superimposing, on the line of transmission 7 connecting the beacon 1 and the device transmission 2, by means of the control device 2, a AC voltage corresponding to the messages sent and a direct current.
- a second step is to short-circuit for direct current only, using the second interface 9, the transmission line 7, during the reception, by means of the second interface 9, of a information 10 relating to the presence of the vehicle 5 to proximity to beacon 1.
- the next step is to detect the short circuit by means of the control device 2.
- a fourth step is to delay, using the control device 2, switching C between the Mn messages and Mn + 1 messages, by transmission, always by means of the control device 2, one or several additional Mn messages Mns.
