Definitions
- the invention relates to machine and system control, in particular for lubrication systems and crane systems, with an angle of inclination working pulse generator for generating control pulses.
- Such controls are, for example, of lubrication systems, in particular Wheel flange lubrication systems in rail vehicles are known.
- Wheel flange lubrication in rail vehicles serves the purpose of Wear of the wheel and the rail in the area of the wheel flange to reduce.
- Wheel flange lubrication Bogies of locomotives but also on other rail vehicles kind of like trams.
- the main lubrication is done with waterproof and cold-resistant lubricants, the Lubrication pulses are triggered by a controller.
- the lubricant is sprayed onto the wheel flanges using compressed air and while driving automatically on the flanks of the wheel flanges transfer subsequent wheel sets.
- Wheel flange lubrication systems are from the Practice known in various embodiments.
- a fundamental problem with wheel flange lubrication is that Trigger lubrication pulses at the correct time and apply the lubricant the right place, namely the flange of the straight on the rail running wheel to apply. So far, these problems have been tried with path-dependent and / or time-dependent and / or arc-dependent Controls to solve. With the path-dependent control, one is released determinable distance, for example every 200 meters, a lubrication pulse triggered. The distance is measured via a displacement sensor, whereby it is irrelevant whether the train moves on a straight line or one Bow drives.
- the lubrication pulse is generated using a Control triggered, the pulse and pause times are freely adjustable.
- a pulse generator that is known from practice and is dependent on the inclination angle consists of a hanging on a thread over a magnet arranged ball.
- the on ball attached to the thread end held by the magnet In the horizontal position of the rail vehicle as well at only low angles of inclination and / or low centrifugal forces, the on ball attached to the thread end held by the magnet.
- the on ball attached to the thread end held by the magnet At a increasing angles of inclination are those caused by gravity Mass forces greater than the magnetic holding force, so that by thread and ball-formed pendulum is deflected.
- a similar triggering can caused by the magnetic holding force via increasing centrifugal forces will.
- the invention is based on the object , while avoiding the disadvantages mentioned, of providing a machine and system control which enables continuous measurement of the angle of inclination and, moreover, allows simple zero point adjustment without the aid of measuring tools.
- the pulse generator is a liquid controlled inclination angle sensor, which comprises at least one measuring chamber which is partially filled with a liquid medium. Due to the inclination of the machine or system and the centrifugal forces that occur, the liquid in the measuring chamber of the inclination angle sensor is deflected almost without delay so that a continuous measurement of the inclination angle of the machine / system is possible. When a freely definable angle of inclination is exceeded, the control pulse for actuating the machine and system control can then be triggered.
- the deflection of the liquid medium in the measuring chamber takes place continuously and without a substantial time delay, the deflection of the liquid medium from the rest position being proportional to the inclination angle of the machine or system to be controlled.
- the Inclination angle encoder preferably having two measuring chambers Differential capacitor formed. Due to the inclination of the in the The inclination angle sensor arranged measuring chamber changes Liquid level within the interconnected measuring chambers of the Tilt angle encoder, which in turn changes capacity in the two Measurement chambers.
- the ratio of through the different Capacities formed are a measure of the deviation of the liquid level Tilt angle encoder and thus the machine / system to be controlled by the horizontal starting position.
- the inclination-dependent displacement of the in the inclination angle encoder located liquid medium is optically measurable.
- trained inclination angle sensor has the inclination angle sensor preferably only a single measuring chamber, partially with the liquid medium is filled.
- To determine the inclination of the Tilt angle encoder or the machine / system to be controlled are on two opposite sides of the measuring chamber a light source and a Optical sensor arranged so that in the horizontal starting position light beam emitted by the light source above the Liquid surface runs.
- the inclinometer is inclined the light beam is cut by the shifting liquid level and steamed. The degree of attenuation of this light beam is used for the determination the deviation of the inclination angle sensor or the one to be controlled Machine / system from the horizontal starting position.
- the maximum zero point deflection is ⁇ 5 °.
- the adjustment device In addition to this zero point adjustment, it is possible with the adjustment device, the The angle of inclination can be freely set generates a control pulse. Thus, the responsiveness of the control according to the invention to the respective application or Machine / system type can be adapted.
- the machine and System control includes a computer for controlling the pulse generator, wherein in a memory of the computer the determined for each Liquid level in the at least one measuring chamber Degree of deflection of the pulse generator or the machine / system is stored.
- Machine and system control is proposed that this for Control of arc-dependent wheel flange lubrication systems for rail vehicles is used.
- Wheel flange lubrication system is therefore possible to directly on a To be able to react to the change in the inclination angle of the rail vehicle.
- the advantage is also achieved that when driving straight ahead a start-up Oblique position of the track level by the inclinometer according to the invention is detected and used to trigger a lubrication pulse.
- Lubrication device 1 shows an example of the structure of a wheel flange lubrication device shown.
- the lubrication device itself has a lubricant container 1 in which oils, fluid greases or also biologically as lubricants degradable lubricants are arranged as a supply.
- the one in Lubricant reservoir 1 is stored with compressed air from a lubricant Compressed air point 2 with an inlet pressure of maximum 10 bar via a Stop valve 3 with ventilation and a pressure regulator 4.
- Lubricant reaches at least one via a lubricant line 5 Lubricant dosing pump 6.
- Each lubricant dosing pump 6 is additional connected to the compressed air source 2 via a pressure line 7.
- a pulse generator 8 is used to control the lubricant metering pump 6 provided with which spray lubrication processes of the lubricant dosing pump 6 can be triggered.
- Fig. 1 Find embodiment of a bow-dependent wheel flange lubrication system two lubricant dosing pumps 6 Use.
- the illustrated Embodiment for a grooved rail, such as for Trams used is of course also on one Overhead rail, as used for normal train operations, transferable.
- the compressed air transports the Lubricant as a lubricant-air mixture either directly or via a Flow divider 10 through the lubricant-air mixture line 11 to one in the Spray nozzle 12 arranged near the wheel flange Lubricant on the respective wheel flange of the rail vehicle sprayed on.
- 2a to 3a are two exemplary embodiments of one Pulse generator 8 formed. As can be seen from the illustrations, it is about the pulse encoder 8 used is an inclination angle encoder.
- Tilt angle sensor 8 is designed as a differential capacitor
- the top and bottom of the inclinometer 8 as Capacitor plates 13 are formed.
- the Measuring chambers partially filled with a liquid 16.
- the the measuring chambers 15 dividing web 14 has at least one opening 17 which the Passes the liquid 16 from one measuring chamber 15 into the other Measuring chamber 15 allows. That way as a differential capacitor designed inclination angle transmitter 8 works as follows:
- the liquid level changes within the measuring chambers 15, since the liquid 16 can enter one measuring chamber 15 into the other measuring chamber 15 due to the opening 17 in the web 14. Due to the different liquid levels in the individual measuring chambers 15, different capacitances C 1 and C 2 result in the measuring chambers 15, so that the ratio C 1 / C 2 is no longer 1.
- the ratio of the capacitances C 1 and C 2 formed by the different liquid levels is a measure of the deviation of the inclination angle sensor 8 from the horizontal starting position. From a freely definable value of the ratio C 1 / C 2 , a pulse is generated that triggers the actuation of the machine and system control.
- Inclination angle encoder 8 is the measurement of the inclination angle dependent Displacement of the liquid 16 optically.
- the inclination angle sensor 8 has only one in this embodiment Measuring chamber 15, which is partially filled with a liquid 16.
- On two opposite sides of the measuring chamber 15 are one Light source 18 and an optical sensor 19 opposite to each other arranged.
- An inclination angle sensor 8 configured in this way works as follows:
- Fig. 3a In the horizontal starting position shown in Fig. 3a is one of the light beam emitted by the light source 18, for example an infrared beam, above the liquid level in the measuring chamber 15, so that this is measured undamped by the optical sensor 19.
- the light source 18 for example an infrared beam
- the liquid level within the measuring chamber 15 is shifted so far that it cuts the light beam 20 emitted by the light source 18.
- the optical Sensor 19 receives a weaker pulse than that in the horizontal starting position with the undamped light beam 20 is the case.
- the Measure of the attenuation of the signal received by the optical sensor 19 is proportional to the distance traveled by the light beam 20 through the liquid 16 travels. Since this in turn is directly dependent on the degree of Deflection of the inclination angle sensor 8 from the horizontal starting position, can a control pulse for actuating the machine and Plant control can be derived.
- the dampening effect of the liquid 16 on the light beam 20 can also be amplified in that the Liquid 16 is colored.
- a machine and system control designed in this way draws is characterized in that the as a liquid-controlled inclinometer designed pulse generator 8 almost instantaneous a direct measure of the Deflection of the inclination angle sensor 8 and thus the machine / system the horizontal starting position, which is used to operate the control can be used.
- the liquid-controlled inclination angle sensor 8 no special measuring or setting devices.
