Accompanying drawing explanation
Fig. 1 is the structural drawing of a specific embodiment of seismoreceiver polarity tester of the present utility model.
Embodiment
For making above and other object of the present utility model, feature and advantage can become apparent, cited below particularly go out preferred embodiment, and coordinate institute's accompanying drawings, be described in detail below.
As shown in Figure 1, Fig. 1 is the structural drawing of seismoreceiver polarity tester of the present utility model.This seismoreceiver polarity tester is made up of input sampling circuit 1, signal conditioning circuit 2, interface circuit 3, microprocessor system 4, display translation 5, audio frequency output 6 and power circuit 7.
Input sampling circuit 1 is connected with power circuit 7 with signal conditioning circuit 2, test wave detector polarity chron, the mechanical vibration excitation of manually knocking shell generation is converted into electric signal by wave detector movement, and this electric signal is picked up by input sampling circuit 1, delivers to signal conditioning circuit 2.Signal conditioning circuit 2 is connected with power circuit 7 with input sampling circuit 1, interface circuit 3, amplifies the signal that input sampling circuit 1 picks up, delivers to interface circuit 3 more afterwards.Interface circuit 3 is connected with power circuit 7 with signal conditioning circuit 2, microprocessor system 4, and the signal sent here with signal conditioning circuit 2 is sent into microprocessor system 4 under microprocessor system 4 controls.Microprocessor system 4 exports 6 with interface circuit 3, display translation 5, audio frequency and is connected with power circuit 7.First crest direction of the electric signal produced due to the wave detector movement of opposed polarity is contrary, and therefore, the signal that microprocessor system sent into by the wave detector of opposed polarity is different.Microprocessor system 4 calculates under putting software control within it and provides tested string direct current resistance numerical value, knocked single detector polarization state.The direct current resistance numerical value calculated, polarization state are delivered to display translation 5 and are shown by microprocessor system 4, polarization state are delivered to audio frequency simultaneously and export 6.Display translation 5 is connected with power circuit 7 with microprocessor system 4, microprocessor system 4 is sent into direct current resistance numerical value with four and half digital watch show, polarization state is shown with the pilot lamp of different colours.Audio frequency exports 6 and is connected with power circuit 7 with microprocessor system 4, and polarization state microprocessor system 4 sent here points out tester " this wave detector polarity is just " with double-tone, single long prompting tester " this wave detector polarity is negative ".Power circuit 7 exports 6 with input sampling circuit 1, signal conditioning circuit 2, interface circuit 3, microprocessor system 4, display translation 5 and audio frequency and is connected, for whole wave detector polarity tester provides operating voltage.
Seismoreceiver polarity tester in the utility model, after seismoreceiver access tester, by knocking wave detector shell, tests wave detector polarity.The mechanical vibration excitation of knocking shell generation is converted into electric signal by wave detector movement, and this electric signal is picked up by input sampling circuit, sends into microprocessor system through signal conditioning circuit and interface circuit.First crest direction of the electric signal produced due to the wave detector movement of opposed polarity is contrary, and therefore, the signal that microprocessor system sent into by the wave detector of opposed polarity is different.Microprocessor system provides DC resistance display translation, polarity display translation and audio frequency polarity and exports under putting software control within it.When being timing by the wave detector polarity of knocking, tester sends double-tone prompting sound; When being negative by the wave detector polarity of knocking, tester sends single long prompting sound.Digital watch demonstrates the DC resistance of wave detector simultaneously, and precision is at 0.1 Ω.The utility model cost can make up because wave detector quantity is large far below geophone tester, the problem of wave detector polarity test instrument lazy weight.
