Embodiment Construction

[0038] figure 1 It is a schematic diagram of the radar level measuring apparatus 100 according to an embodiment of the present invention, and each component of the radar level measuring device 100 is illustrated as a block diagram.

[0039] The radar level measuring device 100 includes a frequency synthesizer 102 for generating an oscillation signal. The frequency synthesizer 102 includes a control unit 104, a reference oscillator 103, and a phase-locked ring 106.

[0040] The phase-locked loop 106 includes a phase-locked element 108 or a PLL assembly 108, and the reference signal generated by the reference oscillator 103 is supplied to the phase lock element 108 or the PLL assembly 108 via the corresponding input end. Further, the phase-locked loop 106 includes a loop filter 105 disposed between the locking element 108 and the oscillator 110. The phase-locked loop 106 is a closed control loop, and the phase position and / or frequency of the oscillator 110 can be adjusted by the...

Abstract

The present invention provides a radar material level measuring device (100), which includes: a frequency synthesizer (102) for generating an oscillating signal, a high-frequency module (112) for generating a transmission signal according to the oscillating signal, and a An energy supply module (114) for supplying electrical energy to the frequency synthesizer (102) and the high frequency module (112). The frequency synthesizer (102) includes a control unit (104), a reference oscillator (103) and a phase-locked loop (106), the phase-locked loop (106) includes a phase-locked element (108) and an oscillator (110), and the phase-locked loop (106) is arranged to adjust the frequency of the oscillating signal to a target value, and the phase locking element (108) is configured to provide a control signal to the control unit (104) when the frequency of the oscillating signal has reached the target value. The control unit (104) is also configured to start the energy supply module (114) to supply electric energy to the high frequency module (112) before the phase locking element (108) provides the control signal.

Description

Technical field [0001] The present invention generally relates to the field measurement field based on radar. In particular, the present invention relates to a radar material measuring device, a radar level measuring device operating method, a program element of a radar material measurement device, and a computer readable medium containing a program element. Background technique [0002] Radar level measuring device (i.e., radar sensors for material measurement) includes high frequency modules and / or high frequency circuits that are often operated in a timing manner. Such a clock operation involves alternating operational valid period and invalid period, and transmitting the measurement signal toward the filling material in the valid period, and does not transmit the measurement signal during the invalid period. [0003] In order to save energy, at least some of the high frequency modules or high frequency modules are disconnected from energy supply such as voltage supply and / ...
