The tunnel intelligent single line lane indicator has three operation modes including a parameter setting mode, a detecting mode and a normal operation mode. By means of power carrier technology, the tunnel intelligent single line lane indicator is capable of simultaneously transmitting lane indicator control signals while power supply wires supply electricity, thereby the single line realizes supplying electricity and simultaneously transmitting signals, the consumption of copper cables is decreased, and the operation task is reduced.
Description
Technical field
The utility model relates to a kind of track indicator, particularly a kind of intelligent single track truck track pointer that is used for vcehicular tunnel.
Background technology
The track indicator is for convenience of the driving vehicle in the dispatch control tunnel, and a kind of device that in vcehicular tunnel, is provided with.When the track indicator for displaying was green arrow, the state of indicating current road was to allow to move ahead; When the track indicator for displaying was the green arrow in the back side, the state of indicating current road was retrograde; When the track indicator for displaying was the double-sided red fork, the state of indicating current road was forbidden.Vcehicular tunnel takes place when unusual, and the track indicator can be accepted tunnel management personnel's instruction timely and accurately, and vehicle in the reasonable diffluence tunnel avoids causing the generation of the crowded or second accident of vehicle.
When using the traditional vehicle track pointer, tunnel management person's instruction is issued the track indicator by local controller, because the distance between local controller and the track indicator has hundreds of meters distance usually, therefore, the number of cables that needs is more, and construction volume is also bigger.
Summary of the invention
The utility model is intended to provide a kind of easy to use, simple vcehicular tunnel single track truck track pointer of maintenance, this track indicator can receive the instruction at tunnel management station by means of power lead, also state can be fed back to the tunnel management station in real time, realize the bidirectional information transmission.This indicator is normal current except that having, allow current, two-way forbidden, the multiple basic deixis such as indicator is stopped using functions such as self check, test, caution are arranged in addition in the other direction.
The utility model tunnel intelligent single track truck track pointer is achieved through the following technical solutions:
Tunnel intelligent single track truck track pointer comprises communication interface, nonvolatile memory, CPU, power carrier communication unit, coupled circuit, output driving circuit, switching value input circuit, led display unit, power lead and carrier wave concentrator.Be characterized in that described power carrier communication unit is made of the extension frequency carrier chip, be used for CDMA spread spectrum mode and order transmitting terminal or the communication of power carrier concentrator, acceptance is from the control command of local controller or supervisory control comuter, according to control command controlling output circuit driving LED display unit, the show state of led display unit feeds back to CPU by input circuit, sends local controller to through power carrier communication unit power lead again.Can carry out basic parameter settings such as carrier communication to this indicator by communication interface.
Tunnel intelligent single track truck track pointer described in the utility model has three kinds of mode of operations: the one, and parameter is provided with pattern, and the 2nd, detecting pattern, the 3rd, normal mode of operation.Switch between described three kinds of patterns by communication interface control indicator, can control indicator by the carrier communication unit and between detecting pattern and normal mode of operation, switch.
Under described detecting pattern, the various display units of track indicator circulation are in turn lighted, and the confession maintainer observes display unit and whether driving circuit is intact; Under described normal mode of operation, indicator is checked earlier whether contradiction of display command in the back that takes orders, correctly send demonstration again until order.Under described two kinds of patterns, indicator can judge whether that fault takes place, if fault is arranged, then described indicator in time feeds back to local controller.
Tunnel intelligent single track truck track pointer described in the utility model can be in the control signal of transfer car track pointer in the power circuit power supply by PLC technology, realized that single line not only powered but also the number of delivering a letter, and saved the copper cable consumption, reduced construction volume.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to accompanying drawing 1, communication interface 101 designs are on control circuit board, described communication interface can be RS232 or RS485, communication interface 101, nonvolatile memory 102 and CPU103 link to each other with power carrier communication unit 104, coupled circuit 105 is the coupled circuits between carrier wave device and the power lead 109, and switching value input 106 links to each other with led display unit 108 respectively with circuit output driving circuit 107.
Referring to accompanying drawing 2, carrier wave concentrator 201 links to each other with local controller or supervisory control comuter, and different track indicators 202,203 also link to each other with local controller or supervisory control comuter respectively with 204.
The installation site of considering the track indicator is higher, and described communication interface also allows to exist jointly with radio transmitting device, to be user-friendly to.Like this, after the track indicator is in place, utilize infrared transceiver device that the carrier communication parameter can be set easily, and can the test indicator duty, for maintenance work provides convenience.
The output circuit driving element can adopt relay, also can adopt transistor or controllable silicon, output driving circuit 107 pilot relays or transistor or controllable silicon, relay or transistor or controllable silicon contact control led display unit 108, switching value input circuit 106 feedback points take from relay another to the contact, can reflect by input circuit 106 whether the work of output loop normal like this.Input circuit and output circuit comprise six loops respectively, common single track truck track pointer is used four loops wherein, the red fork of forward, the green arrow of forward, reverse red fork, reverse green arrow are controlled in four loop outputs respectively, and these four loops can demonstrate described four kinds of duties by display unit 108; The single track truck track pointer of band turn marking can use five loops wherein.
Under the normal mode of operation of track indicator, the carrier wave concentrator 201 that links to each other with local controller sends to track indicator 202,203 or 204 with control command or querying command, track indicator 202,203 or 204 is made corresponding change according to the requirement of carrier wave concentrator 201, and the result is returned to carrier wave concentrator 201.
