Definitions
- the invention relates to a vibrating plate system, comprising a composite of at least two vibration plates mechanically coupled to each other via a coupling device.
- a vibratory plate system has a composite of at least two vibration plates mechanically coupled to one another via a coupling device and a control transmitter for outputting control data to the vibrating plates.
- Each of the vibrating plates in turn has a receiving device for receiving the control data and a traction drive, which should allow at least a forward and backward method of the vibrating plate. It is not necessary that the single vibrating plate is steerable. Rather, the coupling of the vibrating plates to the composite according to the invention makes it possible to direct the composite as a whole.
- a position-determining device for determining the position of the relevant vibration plate within the composite is provided for each vibration plate.
- the position determining device it is possible to determine or determine exactly at which point the relevant vibrating plate is. If e.g. three vibratory plates coupled side by side, one vibrating plate is left, the second in the middle and the third right. Similarly, three vibratory plates can be coupled in series, with the first vibrating plate at the front, the second in the middle and the third at the back. In this way, it is possible that each vibration plate "knows" what position it occupies within the network.
- a control memory is provided for each vibration plate, are stored in the control rules.
- a control rule defines a relationship between a control measure for driving the traction drive of these vibratory plates (eg, driving in the forward direction, driving in the backward direction) depending on the position. tion of the vibration plate and a given by the control data control information.
- each vibration plate has a control device for selecting an appropriate control rule depending on the position of the vibration plate and the control information and for driving the travel drive in accordance with the control rule.
- the rule memory may e.g. in the form of a table of values. For this purpose, certain control measures for the travel drive of the relevant vibration plate are deposited, which are to be carried out depending on the previously determined or determined position of the vibration plate within the network and in dependence on the received control data. Since the individual vibrating plate knows where it is in the vibrating plate system, it can use the control memory to select the correct control rule whenever control information comes from the control device.
- the mean vibration plate can also be moved in the forward or backward direction, so that a total of cornering is achieved.
- the control transmitter preferably has a remote control transmitting device, so that the control transmitter and the receiving device are part of a radio, a cable or an infrared remote control.
- An infrared remote control can offer advantages in practice, as it certain, per se known security requirements are easy to achieve.
- each of the vibrating plates has transmitting means for transmitting the control data previously outputted from the control transmitter and received by the receiving means. That is, first, each of the vibrating plates, with the aid of its receiving device, receives the control data from the control transmitter. Thereafter, each of the vibrating plates sends the received control data - for example, according to a predetermined timing scheme - so that the vibrating plates can exchange and adjust the control data with each other.
- the transmitting devices of the vibrating plates may preferably be part of a radio, a short-range radio (Bluetooth) or an infrared link. Furthermore, it is possible to make a cable connection between the vibrating plates.
- control transmitter can transmit the control data via cable to at least one of the vibrating plates. These control data are then transferred from one vibrating plate to the remaining vibrating plates, so that all vibrating plates have the same "information level".
- each of the vibrating plates it is not necessary for each of the vibrating plates to communicate with every other vibrating plate in the composite. Rather, it may also be sufficient that one vibrating plate exchanges data with only one or at most two further vibrating plates.
- a closed chain can be formed, so that one vibrating plate delivers information to only one further vibrating plate until the information finally - passed on through several vibrating plates - returns to the original vibrating plate and the "information chain" is closed.
- the control transmitter gives a timing pulse and sends during a first time clock, the control data as control telegram, which is received by the receiving means of the vibrating plates.
- each of the vibrating plates transmits, via its transmitting device, depending on its position, one after the other in a time interval assigned to the relevant vibrating plate, to the respective other vibrating plates. This means that the vibrating plates successively repeat the control telegram received from the control transmitter and send it to the remaining vibrating plates. In this way, each vibrating plate indicates what kind of control telegram it has received.
- Control data are transmitted at the same time, either a particular coding form is selected or the transmission is carried out at different transmission frequencies. In that case, it is possible, for example, for all the control data to be transmitted and received essentially permanently, the data being differentiated with regard to their transmission frequency. It is also possible to install a bus system or a local network (eg Ethernet) in a simplified manner in order to exchange the data in the form of data packets.
- a bus system or a local network eg Ethernet
- a balancing device In each vibration plate, a balancing device is provided, with which the control telegrams sent from the control transmitter and from the other vibrating plates and received at this vibrating plate can be compared during a cycle of timings.
- the balancing device thus compares in each time cycle whether the control telegram received from its associated vibration plate coincides with the control telegrams received from the other vibrating plates. In case of deviations appropriate security measures can be taken. Only when the various control telegrams match does the control measures which can be derived from them and are desired by the operator be taken.
- a cycle of timing starts with the timing for sending the control message from the controller. It ends with the timing for sending the control telegram from the last vibrating plate. This is followed by a new cycle, which is initiated again with the transmission of a control telegram from the control transmitter.
- control transmitter which initially sends a control telegram in the manner described above and then releases (pauses) a corresponding number of clock cycles, during which the vibration plates can sequentially send their control telegrams in a predefined manner.
- the matching device issues a stop command to the control guiding device of their associated vibration plate when the received control messages differ during a cycle of clocks from each other.
- the control device stops the traction drive, so that the vibrating plate is in a safe state. Any risk of objects or persons in the environment of the vibrating plate system is then excluded.
- the adjustment device supplies either only the control device of its own vibration plate or the entire vibration plate system with a stop command.
- Stopping the traction drive may include reducing the speed of a drive motor and / or reducing vibrations used to propel the vibrating plate and soil compaction.
- a drive motor are placed on the respectively associated vibration plate at idle speed, in which he no longer drives the traction drive.
- the matching device gives a drive command to the control device when the received control telegrams are identical.
- the control device can control the travel drive in accordance with the control telegrams and the associated control rules, so that the vibration plate system can be moved in the desired manner.
- a proximity detection device for generating a stop command for the control devices of all vibration plates of the vibration plate system when a predetermined minimum distance between the control transmitter and the composite of vibration plates is exceeded.
- infrared remote controls for self-propelled implements are described having such a short-range detection device.
- an infrared near-range radiation with an intensity substantially lower than the control radiation is additionally provided by a control device carried by the operator is sent out.
- this near-field radiation can only be received with sufficient intensity in the vicinity of the transmitter.
- the generation of electrical signals caused by the control radiation is suppressed in the receiving unit on the vibration plate, which would otherwise cause the drive of the working device.
- the implement can be operated as long as it is in the reception area of the control radiation, but outside the range of the near-field radiation. If a predetermined safety distance between the operator and the implement is undershot, ie if the near-field radiation is received by the receiving unit attached to the implement, the implement is shut down.
- Such a short-range detection device is also expedient in the present vibrating plate system in order to prevent the operator from approaching too closely to the vibrating plate system. If the operator falls below the predetermined minimum distance with the control transmitter carried by him, the vibrating plate system is brought to a standstill.
- the traction drive is formed by a vibration exciter.
- a vibration generator usually has e.g. two parallel, counter-rotating unbalance shafts on whose phase angle is mutually variable.
- a resulting force vector of the oscillations arises which, depending on the phase position in the direction of travel of the vibration plate, can be tilted forwards or else backwards.
- suitable synchronization of the imbalances it is also possible to set a so-called state shaking, in which the resulting force vector is directed vertically.
- the vibrating plate system it is not necessary for the vibrating plate system according to the invention that the individual vibrating plates are steerable. Rather, it is sufficient that the vibrating plates can only be moved in the forward and backward direction.
- vibration plates can also be used in the vibrating plate system, which are steerable as well. Preferably, however, then the steering should be blocked or disabled, so that the vibrating plates actually only in Forward and reverse direction can drive.
- the vibrating plates are preferably substantially rigidly connected by the coupling device.
- the coupling device may also include elastic elements, such as e.g. Have rubber buffer, which allow a certain relative mobility of the vibrating plates to each other.
- a completely rigid coupling of the vibrating plates would lead to a behavior of the vibrating plate system, which is comparable to that of a rigid roll bandage. Smaller bumps in the surface to be compacted would be equalized in this rigid coupling. Troughs, on the other hand, would remain uncompressed in this case - as well as in compaction rollers.
- the vibrating plates could each adapt to the run over by them underground and thus “snuggle up” in particular with not completely flat ground on the contour.
- the coupling device can be e.g. screw on the existing protective frame of the vibrating plates, wherein a sufficient number of connecting the vibrating plates coupling beams should be provided.
- the vibrating plates can take an angle to each other, which is limited by the allowable deformability of the elastic elements (rubber buffer).
- FIG. 1 shows a schematic plan view of a vibrating plate system according to the invention
- Fig. 2 is a table of control rules; 3 shows a diagram with cyclically transmitted control telegrams; and
- FIG. 1 shows a schematic plan view of a vibrating plate system according to the invention, which has three vibratory plates which are mechanically coupled to one another, namely a first vibrating plate A (reference numeral 10), a second vibrating plate B (reference numeral 20) and a third vibrating plate C ( Reference numeral 30).
- the vibrating plates 10, 20, 30 are coupled together via a coupling device.
- the coupling device has a coupling carrier 1, which is e.g. by a steel square tube, a steel beam o. ⁇ . can be formed.
- Component of the coupling device are further rubber buffer 1 1, 21 and 31, via which the coupling carrier 1 is attached to the vibrating plates 10, 20, 30.
- a plurality of coupling carriers 1 can also be provided.
- the coupling carrier 1 thus ensures a substantially rigid connection of the vibrating plates 10, 20, 30 with each other.
- the vibrating plates are held parallel to each other in the direction of travel.
- the vibration plates 10, 20, 30 are due to the coupling via the rubber buffers 1 1, 21, 31 relative to each other in certain, by the elasticity and deformability of the rubber buffer 1 1, 21, 31 predetermined limits to each other movable.
- the vibrating plates 10, 20, 30 can rotate about the three spatial axes relative to their attachment point on the coupling carrier 1.
- the mobility allows the vibratory plate system to adapt to uneven ground and to equalize smaller obstacles.
- Each of the vibrating plates 10, 20, 30 consists in known manner of a drive, e.g. an internal combustion engine having upper mass 2 and a relative to the upper mass 2 resiliently movable lower mass 3, which has a ground contact plate and the ground contact plate acting on vibration exciter.
- a vibration exciter has already been described above with reference to the prior art.
- the vibration exciter used in the invention does not differ from the known vibration exciters.
- a so-called two-wave exciter is suitable in which two imbalance shafts arranged parallel to one another rotate positively in opposite directions and thereby generate a resultant oscillatory force.
- the resulting force not only causes a vibration to compact the bottom, but also at the same time corresponding phase position of the imbalance shafts to each other, a propulsive effect in the direction of travel (forward or backward).
- the phase angle of the imbalance shafts should therefore be changeable with the aid of a known phasing device.
- the vibration exciter thus also forms the drive for the individual vibration plate.
- each of the vibrating plates 10, 20, 30 is equipped with a drawbar 4, at the end thereof each a handle 5 and optionally controls for driving the drive on the upper mass 3 or for changing the phase position of the unbalanced shafts are provided in the vibration exciter.
- the drawbar 4 and the handle 5 can then be used by the operator for manual guidance of a vibrating plate when the vibrating plates 10, 20, 30 are not connected by the coupling carrier 1.
- each of the vibrating plates 10, 20, 30 can also be used advantageously in standalone mode. Only by coupling with the aid of the coupling carrier 1, the vibrating plate system according to the invention is formed. Due to the high total mass of the vibrating plate system, it will then be appropriate to fold up the drawbars 4, since they are inoperative in this operating condition and can not be reasonably operated by the operator because of the excessive manual forces required.
- the control of the vibratory plate system is preferably carried out by remote control, e.g. a radio or infrared remote control.
- remote control e.g. a radio or infrared remote control.
- an infrared remote control is shown, to which a control transmitter 6 serving as a transmitting device and respectively associated with the vibrating plates 10, 20, 30, e.g. trained as infrared eyes receiving devices 12, 22, 32 include.
- control transmitter 6 By means of keys, switches or levers on the control transmitter 6, the operator can input his control wishes, which are then supplied via the infrared link as control data to the vibrating plates 10, 20, 30 and received there by the receiving devices 12, 22, 32. The control data are then supplied in each of the vibrating plates 10, 20, 30 of a control device, not shown.
- each vibration plate 10, 20, 30 has its own throttle lever for the drive motor.
- the throttle levers on the vibrating plates 10, 20, 30 are pulled one after the other or the direction control levers are actuated one after the other, so that the one vibrating plate already starts before the other vibrating plates on speed. The entire system then moves from the beginning in an undefined direction not wanted by the operator.
- the vibration plate system has such a large mass that a manual correction of the direction of travel is very laborious.
- the operator would need several remote control devices that he would have to operate artistically at the same time to achieve the desired drivability.
- a single control transmitter is sufficient for controlling.
- the necessary controls are provided, with which e.g. Predictive, reverse, left-hand, right-of-way and stand-shake, as the operator would do with a single vibratory plate.
- the vibrating plate system behaves according to the specifications of the operator.
- control transmitter 6 sends - e.g. in the form of infrared signals - the control data as control telegrams to all three vibrating plates 10, 20, 30, where they are received by the receiving means 12, 22, 32.
- each vibration plate 10, 20, 30 has a position-determining device 13, 23, 33.
- the position-determining devices 13, 23, 33 in the form of rotary switches are respectively attached to the ends of the drawbar 4.
- switches, buttons, encoders, etc. can be used. It is important that each of the vibrating plates 10, 20, 30 receives information about where in the composite it is located.
- each of the position-determining devices 13, 23, 33 can be equipped with a GPS system. be allowed by the evaluation of satellite signals a very accurate position determination in an earth coordinate system is possible.
- the position-determining devices determine, based on their relative positions with each other, which of the position-determining devices in the middle, which is arranged on the left and which on the right (in the case of three vibration plates). In this case, runtime differences of signals can also be evaluated.
- each of the vibrating plates is capable of automatically determining its position within the composite itself.
- the rotary switch serving as the position determining means 13 is set in a position corresponding to the information "left". Accordingly, the vibration plate 10 knows that it is in the left side in the triple compound. Accordingly, the rotary switch 23 of the vibrating plate 20 is in the "center” position while the rotary switch 33 of the vibrating plate 30 is set to "right".
- FIG. 1 represents only one embodiment of a vibrating plate system according to the invention.
- other arrangements e.g. with two, four or more vibratory plates, possible.
- the vibrating plates are arranged in a row next to each other.
- the vibrating plates can also be placed in several rows in front of each other or behind each other.
- a kind of "fir tree arrangement" can be selected in order to achieve a particularly strong soil compaction.
- each of the vibrating plates 10, 20, 30 has a control memory preferably provided in the control device, in which certain control rules, for example in the form of a value table, are stored.
- a control rule defines a relationship between a control measure for driving the traction drive (phasing of the imbalance shafts in forward or reverse direction) in response to the control information obtained from the control encoder 6 and depending on the position of the vibrating plate. Therefore, the single vibrating plate not only knows which control information (control requests) has been given by the controller 6 by the operator. It also knows - as stated above - the position of the vibrating plate within the overall network and can therefore select from the rule memory that control rule that fits this particular application.
- the controller selects the predetermined control rule depending on the position of the vibration plate and the control information and controls the travel drive / vibrator in accordance with this control rule.
- Fig. 2 shows a table of control rules. Such a table of values is e.g. deposited in each of the vibrating plates 10, 20, 30 as a rule memory.
- the individual vibrating plates 10, 20, 30 are registered as vibrating plates A, B, C in the table.
- the vibrating plate A is arranged on the left, the vibrating plate B in the middle and the vibrating plate C on the right. This position information is known to the vibrating plates A, B, C.
- control measures for the traction drive or for the vibration exciter in dependence on the control information, which were transmitted by the control transmitter 6, result from the table of FIG.
- the travel drives of all three vibrating plates A, B, C are set to move forwards (symbol “+”).
- the reverse applies to the reverse (column "back”, symbol “-”).
- the vibration exciters in the individual vibration plates are adjusted in such a way that they do not generate propulsion, but only a vertical vibration.
- the left-hand side te vibrating plate, so move the vibrating plate A to the rear to allow the smallest possible radius of curvature. Accordingly, the vibration exciter in the vibration plate A receives the control command "-" (reverse drive).
- the vibration plate C on the right is intended to move forwards (control action "+”).
- a "0" or "+” forward vibration can be set, the former allowing for a standstill rotation and the latter for an extended left-hander curve.
- the position of a joystick on the control transmitter 6 can be decisive.
- control data via an infrared link always requires a good line of sight between transmitter (control transmitter 6) and the receiving devices 12, 22, 32. Nevertheless, it can also lead to interference in the signal transmissions.
- control transmitter 6 transmitter
- receiving devices 12, 22, 32 receiving devices 12, 22, 32. Nevertheless, it can also lead to interference in the signal transmissions.
- FIG. 3 shows an example of such a data exchange.
- the serving as a transmitter controller 6 specifies a timing for data exchange. During a first time clock (clock 1 in Fig. 3), the control transmitter 6 sends the control data in blocks as a control message (hatched bar). The control telegram is received by the receiving devices 12, 22, 32 of the vibrating plate 10, 20, 30.
- each of the vibrating plates 10, 20, 30 has its own transmitting device, which is preferably integrated with the receiving device 12, 22, 32, in order to keep the construction costs low.
- the vibration plate A transmits its control telegram in the second cycle, while the vibration plate B in the third control cycle sends the control telegram in the fourth control cycle, which they have previously received from the control transmitter 6 in the first cycle.
- one of the vibrating plates 10, 20, 30 determines that the control telegrams do not match, it deduces that there is a communication problem.
- the vibrating plate then automatically moves to a safe condition, e.g. in stand vibration or at standstill, in which the drive motor only runs at idle speed. Accordingly, the other vibrating plates will likewise detect deviations of the control telegrams and will in turn enter the safe state.
- a vibration plate after it has detected a deviation of the control telegrams, sends a stop signal to the other vibrating plates.
- the vibrating plates 10, 20, 30 determine that the received control telegrams match, they can take the required control measures, e.g. according to the control rules according to the table in FIG. 2.
- control telegrams are compared, which are received or sent during a cycle.
- a cycle is normally defined by the number of vibrating plates in the vibrating plate system plus the control encoder 6. Accordingly, one cycle for the vibratory plate system of FIG. 1 has four timings, as in FIG. 3 shown. After the expiration of a cycle of four cycles, the control transmitter 6 again sends a control telegram, whereupon the vibrating plates continue with the data adjustment.
- the clocks can be kept very short, eg in seconds or milliseconds.
- Fig. 4 shows the behavior of the vibrating plate system using the example of the clock No. 3 shown in Fig. 3. At this time, only the vibrating plate B transmits, while the control transmitter 6 and the vibrating plates A, C do not transmit. However, the vibrating plates A and C are in receipt to receive and evaluate the control telegram from the vibrating plate B.
- vibrating plate systems according to the invention have essentially been described, in which a communication for information comparison between see all vibrating plates takes place. Likewise, however, it is possible that information matching is performed only between adjacent vibrating plates. However, the vibration plate 20 arranged in the middle in the case of a triple composite (FIG. 1) would then also have to communicate with both adjacent vibrating plates 10, 30. By contrast, the vibration plates 10, 30 arranged on the outside would not communicate with one another, but only with the vibration plate 20 arranged in the middle.
- each of the vibrating plates 10, 20, 30 outside the composite can also be used individually. Since the vibrating plates 10, 20, 30 need not be steerable, then they can not be controlled via a remote control. Rather, the steering takes place exclusively via the drawbar 4 and the handle 5. In individual operation, the receiving device 12, 22, 32 with the integrated transmitter for the data exchange without function.
- the vibrating plate system according to the invention can be controlled reliably and simply on the basis of the uniform control transmitter, the control rules stored individually in the vibrating plates and the optional data adjustment. Particularly advantageous, the control can be supplemented by a direction of travel stabilization, which is described for example in DE-A-100 53 446.
- a movement detection device for detecting an actual value for the driving movement of the vibrating plate system. The actual value is compared in a cruise control device with a setpoint specified by the operator. The setpoint is present as control information from the controller 6.
- the travel control device corrects the travel movement by transmitting corresponding control telegrams to the vibrating plates 10, 20, 30.
- a device must be provided that the control commands of the cruise control device may supplement or even superimpose the control commands from the control transmitter 6. This is possible, for example, in that the control signals are transmitted in different frequency ranges.
- the cruise control device serves to control the individual travel drives for steering the entire vibration plate system, now only a uniform control information is supplied to the entire composite of vibration plates.
- Each of the individual vibrating plates then knows how to behave in order to be able to fulfill the requirements of the cruise control device (left-hand drive, right-hand drive, straight-ahead driving, etc.) which are decisive for the entire system.
- the cruise control device may e.g. be provided only on one of the vibrating plates. Alternatively, however, it can also be provided independently of the composite, and thus from the outside compare the actual value of the travel movement with the user's request.
