Definitions

  • the invention relates to a radio remote control for controlling one or more functions of a crane, preferably a mobile crane.
  • radio remote controls i. wireless remote controls are known, by means of which, although the disadvantages are overcome, resulting from the presence of a cable in wired remote controls, however, known radio remote controls have the disadvantage that they must be tailored to a specific type of crane or a specific customer crane design , d. H. not universally applicable. Since, in principle, each crane has its own generally different from other cranes controls and functions, crane to crane thus also the radio remote controls, which not only makes their production more expensive, but also designed the warehouse accordingly consuming.
  • the publication DE 202 07 722 U1 discloses a radio remote control according to the preamble of claim 1.
  • the present invention is therefore the object of developing a radio remote control of the type mentioned in such a way that it comparatively cheap to produce and reduced compared to known radio remote control effort in warehousing with it.
  • the invention thus relates to a universal radio remote control, in which a special adaptation of the hardware of the remote control to crane or custom Special designs omitted.
  • the specific adaptation of the hand-held transmitter is therefore not via the hardware but via the possibility of free programming of the hand-held transmitter. This applies, for example, to the visualization of the display and the assignment of the keys in the hand-held transmitter.
  • the hand-held transmitter has a fully graphic-capable display in which, for example, certain functions or parts of the crane, which play a role for the planned activity, or the position of these parts are displayed.
  • the hand-held transmitter has one or more function keys, which consist of at least two actuators, one of which represents an off / on button and another one responsive to the actuation pressure analog button.
  • the actuator is two-channel. It is conceivable that the operator of the remote control can thus operate by varying operating force analog functions. This is for example advantageous if continuously or stepwise certain parameters are to be changed.
  • An example is the Verbolzung that can be performed with variable bolt speed, which is possible, as stated, by a variation of the operating pressure of the corresponding assigned function key of the remote control radio remote control.
  • the hand-held transmitter has a release button and / or an emergency stop button.
  • the hand-held transmitter is constructed very compact, d. H. that the usual controls such as master switch etc. omitted.
  • the radio transmission via Bluetooth, infrared or radio is realized.
  • the Bluetooth transmission has the advantage of being approved in all countries. It should be understood, however, that the invention is not limited to this transmission technique and that other communication techniques may be used. by means of which wireless signals or information can be transmitted.
  • the hand-held transmitter can thus have transmitting means which are designed in such a way that the signals coming from the hand-held transmitter are transmitted wirelessly, for example via Bluetooth. Also, a connection or data transfer by means of cable or docking station, for example, to another remote control is conceivable.
  • the radio remote control further comprises one or more master parts which have receiving means by means of which the signals emanating from the hand-held transmitter can be received.
  • the crane comprises only one such master part or several master parts, which can be addressed by means of a transmitter or received from the remote transmitter signals and use or control to control the crane or crane functions or forward.
  • a master part can have one or more hand transmitters and a hand transmitter can be assigned one or more master parts.
  • the free programmability refers in a preferred embodiment of the invention not only on the remote control, but also on the one or more master parts mentioned.
  • the master part can contain control links, which are freely programmable in the master part, so that it is possible to select which control functions should be executed or relayed via the master part.
  • the master part has interfaces, preferably via bus interfaces for crane or vehicle control.
  • the interfaces are preferably two-channel (2 x CAN and 2 x LSB).
  • the master part or the receiving means can also be designed with two channels. It is conceivable that the entire arrangement is designed with two channels, which brings a safety advantage.
  • solenoid valves can also be connected directly, for which purpose the radio remote control has current or switching outputs.
  • Corresponding actuators can also be controlled via the CAN bus.
  • the master part has transmitting means by means of which signals can be transmitted to the hand-held transmitters.
  • the communication is not only from the hand-held transmitter to the master but bi-directional, i. also in the opposite direction from the master part to the handheld transmitter. This may be required or used to transmit data or information to the hand transmitter (s) by means of the master part. For example, this data or information may be the software for programming the handheld transmitter.
  • the crane has a storage device from which the software can be downloaded, by means of which the master or the master or the handheld transmitter can be freely programmed.
  • an auto-configuration of the hand-held transmitter is conceivable, which takes place in that the hand-held transmitter is programmed after contact with the master part of this according to the specific design of the crane or supplied with software.
  • the visualization of the display and the assignment of the keys in the transmitter can be determined by the software.
  • any control applications can be programmed on the radio remote control or on the remote control.
  • any graphic displays and also status messages can be visualized in the hand-held transmitter.
  • Such status messages may be, for example, diagnostic messages which are transmitted to the hand-held transmitter by means of the master part. This results in the possibility that the operator receives a diagnostic message on the remote control and then can investigate a possible error on site with the aid of the diagnosis means.
  • the radio remote control has a plurality of master parts, which are designed such that data can be exchanged between the master parts. It is also conceivable that the radio remote control has a plurality of handheld transmitters, which can also be designed such that they communicate with each other or that data is transmitted from one to the other handheld transmitter.

It is also conceivable that the radio remote control system has a first unit which can be connected to a second radio remote control. The first unit may, but does not have to be, a radio remote control.
  • the term "second radio remote control" thus does not necessarily mean that a further "first" radio remote control must be provided. It is possible that only the second radio remote control or the handheld transmitter sends.
  • first unit and the second radio remote control are designed such that one or more functions of the first unit are taken over by the second radio remote control or vice versa, when the first unit and the second radio remote control are connected to each other.
  • connection between the two radio remote controls or between the first unit and the second radio remote control is arbitrary per se. It is conceivable that the connection between the two radio remote controls or between the first unit and the second radio remote control comparable to that of a docking station is designed as a plug connection. It is conceivable that when recording the second radio remote control in the first radio remote control or unit, at the same time a connection is established, which can serve for the transmission of energy and / or data.
  • the second radio remote control may be a hand transmitter of a radio remote control according to one of the claims.
  • the radio remote control system has features of the radio remote control according to the invention.
  • the radio remote controls are designed such that one or more functions of a radio remote control are taken over by the other radio remote control when the radio remote controls are in communication with each other.
