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.
  • the invention is therefore based on the object of specifying a vibrating plate system comprising a plurality of mechanically coupled vibrating plates, in which relatively simply constructed vibrating plates can be controlled jointly without unnecessary control effort.
  • 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 travel drive of these vibrating plates (eg, driving in the forward direction, driving in the reverse direction) depending on the position the vibration plate and a control information given by the control data.
  • each vibration plate has control means 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 be 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 should 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 middle vibration plate can also be moved in the forward or backward direction, so that a total of cornering is achieved.
  • control transmitter 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 - e.g. according to a given time schedule - so that the vibration plates can exchange and adjust the control data with each other. In this way it can be achieved that a travel movement is always carried out only when an adjustment of the received control data has taken place. Only if all vibrating plates have received the same control information from the controller is there any certainty that this control action should actually be performed. Only then is the corresponding control information implemented by the respective control devices in the form of individual control measures for each individual vibration plate.
  • 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 for a vibrating plate to exchange data with only one or at most two further vibrating plates.
  • a closed chain can be formed, so that in each case one vibrating plate gives information to only one further vibrating plate until the information finally - carried over several vibrating plates - back to the original vibrating plate and the "information chain" is closed.
  • the control transmitter gives a timing pulse and transmits the control data during a first timing as a control message, which is received by the receiving means of the vibrating plates.
  • each of the vibrating plates sends via its transmitting device, depending on its position, one after the other in a timing cycle associated with the relevant vibrating plate, the received control telegram to the respective other vibrating plates.
  • 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. It is then possible, for example, for all the control data to be transmitted and received substantially 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 adjustment means issues a stop command to the control means the vibration plate assigned to it, if the received control telegrams differ from one another during a cycle of clock cycles.
  • 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 balancing device supplies either only the control device of its own vibration plate or the entire vibrating 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 as well as 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, which have such a short-range detection device. So it is from the DE-A-42 21 793 It is known that, in addition to the infrared control radiation provided for the functional control of the working device, an infrared near-field radiation with an intensity substantially lower than that of the control radiation is additionally supplied 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, the short-range radiation is received by the receiving unit attached to the implement, the implement is shut down.
  • Such a proximity detection device is also useful in the present vibratory plate system to prevent too close approach of the operator 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. In the opposite rotation of the unbalanced shafts creates a resulting force vector of the vibrations, which can be tilted depending on the phase in the direction of travel of the vibrating plate forward or backward.

Of course, also vibrating plates can 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 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 that is comparable to that of a rigid drum bandage.
