Definitions

  • the present invention relates to an automatic information system for mobile objects, consisting of response units arranged on the mobile objects, in which information about the respective object is stored, and at least one interrogation unit which, when passing through a response unit, transmits a carrier signal of a first frequency to the latter Energy for the power supply of the electrical circuit parts of the response unit is used, the response unit sending out a response signal modulated with the stored information of a second frequency to the interrogation unit.
  • a ferrite rod antenna is installed on each response unit to receive the carrier signal emitted by the interrogation unit.
  • the response unit also has a second antenna, namely for sending a response signal to the query unit.
  • This response unit is spacious and complex, which is why it is not well suited for flexible use.
  • the invention is based on the object of designing the response unit of the automatic control system of the type mentioned at the outset in such a way that it obtains a compact, easily manageable shape in order to enable flexible use on a wide variety of mobile objects.
  • the response unit according to the invention can therefore be constructed in a very handy form, because it does not require its own energy source and, moreover, only a single antenna in the form of an induction coil in order both to receive a signal supplying the operating voltage and to transmit an information signal to an interrogation unit.
  • the automatic information system mentioned at the beginning can be used to identify mobile objects such as identify rail-bound vehicles or goods moving with conveyor belts or the like.
  • the information system can also be used to direct mobile objects to specific locations intended for them.
  • information (address of goods to be shipped, size and shape of a motor part, etc.) must be requested from each of the objects to be transported to different locations, with which the desired transport destination is linked.
  • the mobile objects are equipped with response units in which information relating to the desired destinations can be stored for the respective object.
  • an interrogation unit which reads the information from its response units as the objects pass and transmits them to a central computer, which then takes over control of the transport route.
  • the input of the response unit AW contains two resonance circuits, a first of which consists of an inductor L1 and a capacitor C connected in parallel thereto and a second of the inductor L1 which is formed of this capacitor C connected in parallel and a further inductor L2 connected in series.
  • these two inductors are realized by a single induction coil provided with a tap.
  • the induction coil fulfills the task as a receiving antenna for a carrier signal of frequency f 1 ′ generated and emitted by the oscillator 01 of the interrogation unit AF.
  • the second resonance circuit composed of the inductors L1, L2 and the capacitance C is tuned to this frequency f 1 .
  • a rectifier D is connected to this second resonance circuit, which converts the carrier signal of frequency f 1 into a DC supply voltage VS for the electronic components of the response unit. If the response unit AW now receives a carrier signal of frequency f 1 while driving past the interrogation unit AF, the one stored in the memory S becomes Information using a modulator M modulates a carrier signal of frequency f 2 , which comes from an oscillator 02.
  • the induction coil which together with the capacitance C forms a resonance circuit tuned to precisely this frequency f 2 , sends the information signal to the interrogation unit AF.
  • the interrogation unit has the same resonance circuits tuned to the frequencies f 1 and f 2 as the response unit.
  • the interrogation unit is expediently also equipped with only a single induction coil, which is both part of the first resonance circuit and part of the second resonance circuit.
  • the information signal received by the interrogation unit via the induction coil reaches a demodulator DM, at the output of which the information can be tapped from the memory S of the response unit.
  • the detected information is finally transmitted to a central computer, which then carries out the route control for the mobile objects.
  • the response unit AW is provided with only one induction coil as an antenna for receiving the energy signal and for transmitting the information signal. 2, a very compact and easy-to-use design for the response unit AW is possible.
  • the electronic circuit parts of the response unit are housed in a cuboid, flat housing, around the narrow sides of which the induction coil IS is wound. A trench-shaped indentation in the narrow sides of the housing gives the induction coil a secure hold.
  • a switch or keypad TF is arranged as an input unit (designated E in FIG. 1) for the memory. If a response unit is attached to a mobile object, the current information of the respective object can always be entered into the memory manually using the switch or keypad. The entry into the memory can also be done remotely by means of an opto or ultrasound transmitter. Instead of the keypad TF, the housing would then have to be provided with an opto or ultrasound receiving element.
  • a visual display AZ on the front rivet of the housing provides information about all or part of the memory content.
  • the information that is to be written into the memory can also be transmitted from the interrogation unit to the response unit by modulating this information onto the carrier signal in the interrogation unit.
  • Another external station can also transmit a carrier wirelessly or via a conductor which can be connected to the response unit and to which the information for the memory of the response unit is modulated.
  • Adhesive elements e.g. Magnetic stripes are attached, which allow the response units to be quickly attached to a mobile object (railway wagons, containers, etc.).
