Definitions
- the invention relates to a device for contactless distance measurement between at least two measuring points associated with the measuring points, interconnected by a radio link measuring devices, each having an oscillator stage for generating a frequency-modulated in the sense of a ram- frequency waveform measurement signal, a transmitting and receiving unit for Measuring signals and a connected to an evaluation stage mixing unit for the generated in the respective measuring device and received by the other measuring device measuring signals, and with at least one connected to the evaluation of the measuring devices computer stage for calculating the evaluated in the evaluation levels measurement data and output of the calculated Distances.
- a radio link measuring devices each having an oscillator stage for generating a frequency-modulated in the sense of a ram- frequency waveform measurement signal, a transmitting and receiving unit for Measuring signals and a connected to an evaluation stage mixing unit for the generated in the respective measuring device and received by the other measuring device measuring signals, and with at least one connected to the evaluation of the measuring devices computer stage for calculating the evaluated in the evaluation levels measurement data and output of the calculated Distances
- the invention is therefore based on the object, a device of the type described for contactless distance measurement between at least two measuring points in such a way that with a low cost, a high-resolution distance measurement is possible.
- the invention achieves the stated object in that the evaluation stage of at least one of the measuring devices is connected to a separate from the transmitting and receiving unit for the measuring signals transmitting unit for wireless transmission of the evaluated measurement data to the computer stage.
- the transmitting unit connected to the evaluation stage is connected to the computer stage via a data transmission path separate from the measuring radio link between the measuring devices, then the measuring radio link between the measuring devices can be used exclusively for the transmission of the measuring signals, which is an advantageous prerequisite for the accurate detection of high Speed-changing distance ratios is because the measurement radio link is not additionally burdened by the transmission of the evaluated measurement data and thus the transmission rate of the measurement signals is limited.
- Particularly advantageous conditions arise in this context, if already existing networks, preferably wireless networks for mobile communication, used and the case-proven facilities are used, so that the potential application can be considerably expanded.
- the computer stage for billing the measurement data evaluated with regard to the frequency differences can be assigned in a manner known per se to at least one measuring device and combined with the evaluation stage of this measuring device to form a common computer unit.
- FIG. 1 shows a device according to the invention for non-contact distance measurement between two measuring points in a simplified block diagram
- FIG. 2 shows a representation corresponding to FIG. 1 of an embodiment variant of the device according to the invention
- FIG. 3 shows the temporal frequency profile of the transmitted and received measuring signals of the measuring device of one of the two measuring points
- FIG. 4 shows the temporal frequency curve of the transmitted and received measuring signals of the measuring device of the other measuring point.
- the two measuring devices 1, 2 assigned to each measuring point have the same structure and each have an oscillator stage 4 controllable via a control unit 3 for a measuring signal in the microwave range whose frequency is modulated in the form of a ramped frequency response. Although this is not mandatory, one will is. Although not mandatory, a linear increase or decrease in the frequency response is sought.
- the frequency-modulated measuring signal is fed to a transmitting and receiving unit 5.
- the transmitting and receiving units 5 of the two measuring units 1 and 2 are connected to each other by a measuring radio link 6.
- the measurement signal received by the respective other measuring device 1, 2 is supplied to a mixing unit 7, in which the received measuring signal is mixed with the measuring signal to be transmitted, in order to apply a mixed signal to an evaluating stage 8 connected to the mixing unit 7.
- the evaluated measurement data are forwarded via the control unit 3 after a corresponding processing to a transmitting unit 9, which is connected to a computer stage 10 via a separate from the measurement radio link 6 data transmission link 11, in particular a radio network 12 for mobile communication.
- the evaluated measurement data of the two measuring devices 1 and 2 are therefore provided to the computer stage 10 for offsetting and for output of the calculated distances.
- FIGS. 3 and 4 illustrate the temporal frequency profiles of the transmitted and received measuring signals of the two measuring devices 1 and 2. From FIG. 3, which relates to the measuring device 1, one can see the ram-shaped course of the frequency response U of the measuring signal transmitted at the instant t 0 .
- FIG. 4 shows the frequency curve f 2 of the measuring signal transmitted in the measuring device 2. This measurement signal is sent delayed with respect to the measurement signal of the measuring device 1 by a time T o ff and reaches the measuring device 1 after a transit time T. The measurement signal received by the measuring device 2 in the measuring device 1 is thus opposite the measuring signal of the measuring device 1 by a period of time T. O ff + T offset, which of course also shows in the displacement of the frequency response f 2 'of the received measurement signal.
- the frequency difference ⁇ f ⁇ is calculated analogously from the frequency profiles h and V of the transmitted and received measurement signals of the measuring device 2
- the distance d of the two measuring devices 1, 2 can be determined independently of one another by the time delay T off of the transmitted signals f 1 and h. It is only to ensure a corresponding overlap of the frequency ramps of the transmitted and the received measurement signals and thus for a corresponding order of magnitude of the frequency difference, which may require a rough Vorsynchronmaschine based on the time difference between the transmitted and received measurement signal.
- the mixed signals in the sense of determining the frequency differences .DELTA. ⁇ and ⁇ f ⁇ are evaluated to account for the evaluated measurement signals in the computer stage 10 for determining the distance d. Because of the separate data transmission path 11 for the transmission of the evaluated measurement data, the measurement radio link 6 is not subjected to any additional load due to a data transmission and remains free for the transmission of the measurement signals. Due to the separate data transmission link 11 and the computer stage 10 can be assigned to a separate from the measuring devices 1, 2 output device 13.
- FIG. 2 differs from that of FIG. 1 only in that the computer stage 10 is assigned to one of the two measuring devices 1, 2, so that the distance determination in this measuring device, in the embodiment, the measuring device 2, is performed, and Although as described in connection with FIGS. 3 and 4. But it can also be assigned to both measuring devices 1, 2 computer stages 10, as indicated by dashed lines in Fig. 2 for the measuring device 1. In this case, ensure a mutual exchange of data between the two measuring devices 1 and 2.
- the computer stage 10 can be summarized with the evaluation stage 8 to a common computer unit 14, which preferably also includes the control unit 3.
- Fig. 2 dash-dotted lines indicated that the measurement radio link 6 can also be used for data transmission, if z. B. the transmitting unit 9 of the measuring device 1, the antenna of the radio link 6 with the appropriately formatted, evaluated measurement data acted upon.
