Definitions
- the invention is based on a method according to the preamble of claim 1.
- a sensor system that continuously monitors a measuring section is from the international Application WO 83/00744 known. With this system, forces are applied to an oil line measured with the help of an optical fiber.
- the track monitoring Sensor system is equipped, which continuously location and speed of all records and reports on vehicles on the route.
- the route is from Sensor system monitored essentially without gaps.
- the sensor system also records the condition of the route by reading the pressure and load profile the rail absorbs and thus enables the elasticity and strength of the Track substructure as well as the correct track position and the strength of the sleepers.
- the sensor system is capable of moving from the wheelsets of the vehicles to the Rail transmitted elastic axis vibrations and in addition to elasticity and Strength of the track substructure also to monitor the condition of the vehicles and their wheel sets. There is no need for communication between the vehicle and the monitoring device or an active position report from the vehicle.
- the sensor system has pressure sensors to the threshold back pressure between the rail via the rail clamping plate and record threshold.
- the invention is based on the object of an alternative method for monitoring the running of train tracks indicate which simple sensors are used.
- the invention is particularly suitable for the monitoring of high-speed trains and high-speed routes, at which are the smallest errors in the track bed, on the rail or on the Vehicles can lead to serious accidents.
- both rails of a railroad track system along its entire length with a continuously distributed Sensor system equipped which allows the location and speed of the Track trains, individual wagons and individual axes (for control the presence of the last car, broken axles, broken wheels and Derailments).
- this sensor system also allows condition and Monitor road safety and in particular Rail breaks, threshold breaks and screw breaks, faulty Track layers, hollow sleepers, track warping, waning Load capacity and elasticity of the substructure, changes in the Ballast bed, underwashing the track body and acts of sabotage (loosened or stolen rails, obstacles on the route) detect.
- Essential features of this invention are that Sensor system works independently of the car, i.e. not on special ones Devices on the wagons or feedback from them, and that it is continuously distributed over the route, so not on specific facilities on the route based on their exposed structure more susceptible to damage and theft are.
- the sensor system works with a sensor tape, which is magnetoelastic Has sensors, preferably at short intervals are arranged along the sensor band.
- the hierarchical structure of the sensor system makes it easy possible location and speed of the train on the route too determine and this information for train route and route monitoring to process further.
- Figure 1 shows the track superstructure using the type of attachment W with an advantageous embodiment of the arrangement of a continuous Sensor band 7, which under the rail foot instead of or together with an elastic that is usually installed there.
- Plastic liner is attached.
- the rail 1 is with the concrete sleeper 6 by Epsilon tension clamps 3 and 5 screwed into plastic dowels Threshold screws 2 non-positively clamped.
- the concrete sleepers are specially designed in the area of the rail support.
- Two steel angle guide plates reach into the W-shaped recesses 4 and secure the rail against lateral displacement.
- the Rail stands apart from the plastic liner 8 (Fig. 2) and the combined or built in instead of this plastic liner Sensor tape 7 (Fig. 1) directly on the concrete sleepers.
- the threshold counterforce acts directly as a reaction force of executives appearing when driving on the track.
- the Threshold drag is dependent on the dynamic wheel load Threshold distance and the degree of stabilization of the track.
- the sensor band 7a shown in FIG. 2 is equipped with an impact-resistant jacket.
- a track error occurs at a certain point on the route, for example a rail break, as is assumed in Fig. 3, shows that Sensor signal a change characteristic of the type of error, which is shown schematically in the lower part of the figure using a pulse diagram is shown.
- Sensor signal a change characteristic of the type of error, which is shown schematically in the lower part of the figure using a pulse diagram is shown.
- the Sensor signals rise more sharply in front of the breaking point and rise immediately the breaking point 10 drop abruptly.
- a steady waveform Track defects like hollow ones Thresholds and changes in the ballast bed also create characteristic sensor signals, from which not only the location but also the type of the track error can be determined.
- the route calculator is used for this 11, which is shown schematically in Fig. 3.
- Such route calculator are at certain intervals along the route and preserved their signals from the sensor coordinators SKA, SKB ... (see Fig. 4), which monitor the individual smaller sections A, B ... in the they capture the sensor signals generated there and for the Prepare further processing in the route computer 11.
- the Sensor coordinators also provide power to the sensors or monitoring their function. A suitable for monitoring hierarchical system is shown in Fig. 4.
- the range of the signals requires that the signals are carried out along the route Division of the sensor band into sections, in each of which the signals processed or amplified with repeaters. In order to the attenuation of the sensor signals can be compensated.
- the driving speed of the vehicles need not be exclusive determined over time and place as with other track protection systems be, but is also due to the dynamic load of the Route recognizable. A higher driving speed creates on everyone Place the route a higher load profile. So that is continuous Speed measurement possible, which is not based on discrete location and Time measurements is required (see the schematically shown Sensor signals in Fig. 3).
- the track coordinators SKA ... SKD which are the measurement results of the Evaluate measuring devices 12, as shown in FIG. 4, hierarchically are networked, so that each route coordinator menrerer the measurement results Evaluate neighboring measuring devices and compare them can. Through the hierarchical networking of the measuring devices security redundancy is introduced. If a route coordinator fails someone else can take over its function.
