- a block Gold / Des comprises 4 entries (621) of CdV. These 4 entries make it possible to treat any plan of way whatever its complexity.
- a 5 th entry (622) all or nothing corresponds to a so-called destruction pedal input. It corresponds to the output of an electromechanical detector sensitive to the passage of a vehicle over a defined area. This input, when activated at the logic level "1", which corresponds to the presence of said vehicle, can trigger the destruction, or release, of the route engaged.
- the block Or / Des comprises outputs (631, 632, 633, 634) all or nothing making it possible to control a signal of origin of the route under conditions consistent with the local operating conditions and spacing.
- the all or nothing outputs of the Gold / Des block include: an output (631) for controlling the green light of the operating signal, produced by the excitation of a relay NS1;
- the eyecup is a signal light, usually white and placed at the bottom left of the signal, and which is lit when said signal is passable especially in the case of a visual procedure.
- the Gold / Des block includes other SIL4 or lower safe level all-or-nothing inputs and outputs.
- the block Or / Des comprises an input (625) called “control in opposite direction” and an output (635) called “engagement in the opposite direction”.
- These inputs and outputs (625, 635) make it possible to manage a zone common to two systems according to the invention, that is to say to two sets of blocks each managing a section of track.
- several systems that are the subject of the invention are advantageously used adjacently to control very complex path planes, or to allow the network to evolve by the addition of new branches without having to restart the security of the previous branches.
- the blocks Or / Des and the blocks Ag comprise one or more so-called proportional inputs (541, 641), which allow the acquisition of a signal of variable or scalable value.
- These inputs (541, 641) are of digital or analog type, and allow the acquisition of a proportional signal, for example analog between -5 volts and +5 volts or a proportional signal whose level is coded on 8 bits or more.
- proportional inputs make it possible to include in the criteria for switching on routes, parameters defined by their value, by way of non-limiting example, such a proportional input makes it possible in particular to control the effective lighting of a light signal. green or red.
- the method which is the subject of the invention is illustrated according to a implementation example corresponding to the realization of a route between two ends (101, 103) of the network implementing the two needles (1 11, 1 13) conjugate.
- the realization of a route, until the authorization of the passage of a vehicle on said route comprises 3 steps:
- the route is initially defined by the supervisor using the supervision tool.
- said route is interpreted by the CPU (250) which transmits (71 1) via LNF a selection information to the attention of the first block Or / Des (121) of the route, in order to reserve the said route.
- said Gold / Des (121) block moves from the "free" state to the selected state and transmits (721) a selection order to the downstream block (131) concerned by the route.
- the transition from the free state to the state selected for such a block Gold / Des is realized only if said block is actually in the "free” state and that it intervenes in the route like block of origin or as a destination block.
- the block Ag (131) concerned by the route and downstream a block Gold / Des origin receives the selection order, it passes (725) from the free state to the selected state if no engagement does not oppose it, and this selection causes:
- the first command is sent directly to the needle controlled by said Ag block (131) via one of the outputs (531 FIG. 5) of said block, while the other two commands are addressed to the respective blocks via the LNF.
- the Ag block (131) transmits (721) a selection instruction to the downstream block (733) traversed by the route and so on.
- the last block (123) of the route is always a destination Gold / Des block.
- this last block Gold / Des (123) is selected (720)
- it sends (722) to the original block Gold / Des a notification of end of selection, which ensures that all the blocks traveled by the route have been selected.
- the original block Gold / Des (121) Upon receipt of the notification of completion of selection, the original block Gold / Des (121) initiates the process of engaging the route for the formation of said route.
- the transition from the "selected" state to the "Enabled by an uncontrolled route” state is intended to prohibit any needle control, thus ensuring the continuity and protection of the route, in front of the vehicle traffic who borrows it and during its passage.
- the original Or / Des (121) block passes (730) from the "Selected as Origin” state to the "Enabled by an uncontrolled route as "origin”, and transmits (731) an engagement command to all the blocks (131, 133, 123) avals traversed by the route.
- each block Upon receipt of the latching command, each block passes (735) from the "selected” state to the "locked uncontrolled” state.
- This change of state in the case of an Ag block, allows the locking of the needle that said Ag block controls.
- the reception of the trip initiation command (731) causes in each block traversed by the route the execution of a step (745) for checking the engagement conditions, and, if said engagement conditions are satisfied.
- the block goes into the "controlled on” state and transmits (741) to the original Gold / Des block (121) a notification of transition to the "controlled on” state.
- the original block Gold / Des (121) passes (750) to the state "locked checked” after checking the validity of its own conditions of engagement and controls the opening of the signal allowing the passage of the vehicle on the route.
- the setting of the concerned Or / Des block (121) allows it to define the indication to be presented to the signal according to the established route and the occupation status of the channels.
- the attack of the first zone of the route causes the closure (860) of the original signal.
- the route interlock is deactivated (861). This deactivation causes the blocks (131, 133, 123) to pass to the free state (865). ) as and when the release of the VCs from the route by the vehicle.
- This mode of implementation corresponds to the release of the transit interlock and allows the release of the needles as and when their release by the vehicle, thereby smoothing the traffic.
- said automatic destruction destination, the destruction of the route is initiated (960) by the block Or / Des (123) of destination after the crossing by said vehicle of the set of the route. For example, when the vehicle is a train, and its passage is detected through track circuits, this crossing is determined by a sequence of VC occupancy between the last transit VC and the destination VC.
- the original Or / Des block (121) transmits (962) to the downstream block (131) of the route an authorized destruction instruction, which block passes (965) to the "free” state and transmits (962) downstream block (133) of the route, an authorized destruction instruction and so on.
- This embodiment of the method that is the subject of the invention prohibits any modification of the route until the said route is cleared by the vehicle.
- Figure 10 according to an example of a particular lane plan, it comprises only two ends (1010, 1020) and does not include a needle.
- a lane plan corresponds to a platform lane (1,100).
- the interlockings relating to such a channel plan consist in managing the signals at both ends according to the information provided by associated CoPs (not shown).
- the system that is the subject of the invention is implemented with two Gold / Des blocks (1021, 1022) located at each end of the channel. The absence of Ag block on the corresponding route is taken into account in the so-called parameter layer of the software layer of said blocks Gold / Des (1021, 1022).
- said lane plan comprises 6 ends (1 101, 1 102, 1 103, 1 104, 1 105, 1 106), associated signals and an oblique crossing where the section between two ends (1106, 1 103) intersects another section (1101, 1 104) without switching.
- FIG. 11B the implementation of the system which is the subject of the invention on such a track plan is, according to an exemplary embodiment, carried out by means of two fictitious hands, corresponding to the oblique crossing, which fictitious hands are controlled by Ag blocks (1,121, 1,122).
- these Ag blocks (1121, 1122) controlling fictitious needles cooperate with the Ag blocks (1 123, 1 124) controlling real needles to allow the engagement and the destruction of route safely.
- the Ag blocks (1 121, 1122) controlling fictitious needles are real Ag blocks that are integrated in the LNF network, but do not have the inputs / outputs relating to the commands and controls for moving the needle, or whose functions have been inhibited. Their presence helps manage route incompatibilities.
- the invention achieves the desired objectives, in particular by combining parameterizable generic blocks connected by a ring network, it makes it possible to provide training and validation functions for a route in its entirety by distributing the control and security functions at the level of each generic block.
- the demonstration of the conformity of an installation made from the device of the invention with regard to a security level is greatly facilitated.
- the blocks are based on a generic architecture, the maintenance of the device as a whole and of each block in particular is facilitated.
- the device object of the invention is adapted both to a first installation but adapts and interfaces with any existing interlocking system, including electromechanical.
- the device that is the subject of the invention is evolutionary by the integration of new blocks, corresponding to other switchgear, in the network or by connecting several systems to each other.
