Detailed description of the invention
As it is shown in figure 1, a kind of portable spot check instrument being applicable to wireless vibration measuring, including measuring for being placed on scene The wireless vibration sensor of mechanical shock and the packaged type spot check instrument of built-in radio communication function;Described wireless vibration sensing Device include vibrating sensor, simulated modulation circuit, analog digital converter, the first single-chip microcomputer, the first RF transceiver, power supply and First external antenna, the outfan of vibrating sensor passes sequentially through simulated modulation circuit and analog digital converter and single-chip microcomputer Input is connected, and the outfan of described single-chip microcomputer is connected by the first RF transceiver and the first external antenna;
Vibrating sensor described in the utility model is piezoelectric ceramic vibration sensor core, by piezoelectric effect by equipment Original vibration signal is converted into the signal of telecommunication, and the signal of telecommunication enters analog signal conditioner circuit with analog signal form, to original Acceleration signal does processing and amplifying, filtering, and hardware Integral Processing, and original acceleration signal is processed into rate signal and displacement Signal, signal after process continues to enter analog-digital converter with the form of analogue signal, and analog-digital converter can be by The analog signal digital that analog signal conditioner circuit is come in, enters digitized signal in analog-digital converter and passes through SPI1 Interface and the first single chip part are connected, and the first single-chip microcomputer goes sampling with certain sample rate Fs, and Fs is in this example 32Ksample/s, the first single-chip microcomputer is stored temporarily in ferroelectric memory with the initial data of Fs sample rate collection, the first monolithic Machine is connected with ferroelectric memory with SPI2 contact mouth, and last first single-chip microcomputer is with SPI3 interface and the first RF transceiver part phase Even.
The packaged type spot check instrument of described built-in radio communication function include spot check instrument body, second singlechip, second RF transceiver and the second external antenna, described spot check instrument body is connected with second singlechip, the output of second singlechip End is connected by the second RF transceiver and the second external antenna.The first described RF transceiver and the second RF transceiver Use for coupling.Described RF transceiver is the ATRF212 of atmel company, and frequency range is 779-787M, and RF transceiver leads to Cross 50ohm impedance line to be connected with 780M radio-frequency antenna part, i.e. described impedance line be separately positioned on the first RF transceiver and Between first external antenna and the second RF transceiver and the second external antenna.
As shown in Figure 2, the portable spot check instrument main body of described built-in radio communication function passes through UART and the second monolithic Machine part is connected, and second singlechip is connected by SPI interface and the second RF transceiver part, the second RF transceiver mistake 50ohm impedance cable and 4 parts are connected, and 4 is 780M radio-frequency antenna.
