3, monitoring system of the present utility model has buzzer warning and SMS alarm function, can realize real-time monitoring.
Description of drawings
Fig. 1 is the utility model long distance wireless vibration monitor system structured flowchart.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 is the utility model long distance wireless vibration monitor system structured flowchart, comprise the GPRS wireless data transfer module, management server and at least one vibration monitoring node system, described vibration monitoring node system comprises a plurality of vibration transducers that are fixed on the monitored object, each vibration transducer is connected with the data input pin of vibration detection instrument by the RS-485 bus respectively, the data input pin of described vibration detection instrument is connected with the data input pin of described GPRS wireless data transfer module by the RS232 data line, and described GPRS wireless data transfer module is connected with described management server by GPRS network.
Wherein, the GPRS wireless data transfer module adopts MD-600, and management server adopts the computing machine that CKZDH_ZD1.0 data center software has been installed.The detected information of each vibration transducer is passed to the vibration detection instrument by the RS-485 bus respectively, the vibration detection instrument will be vibrated for information about and pass to the GPRS data transmission module by the RS232 data line, the GPRS data transmission module sends to the data that receive on the network of assigned ip address by GPRS network, management server just can long-rangely read the detection of mechanical equipment vibration value by online, the vibrational state of real time monitoring equipment has really been accomplished remote remote measurement.The duty personnel also can be connected with described management server by LAN (Local Area Network), understands the duty of equipment at any time.
Described vibration transducer is the digital vibration transducer of DSP.Can adopt the DSP-90 vibration transducer, the digital vibration transducer of DSP-90 can provide vibration survey scope ± 50g, ± 2g, and 12 of vibration resolution, frequency range 0-1kHz has warning function in the time of measurement, and the temperature height is limit, the lower bound alarm set point is able to programme.DSP-90 utilizes a data line and ground wire to realize communicating by letter with the vibration detection instrument.Operating temperature range :-40 ℃～+ 85 ℃.The built-in DSP signal processor of vibration transducer carries out FFT (Fourier transform) to vibration data to be analyzed, and calculates acceleration, speed, shift value.Can directly export the vibrational waveform data of time domain and frequency domain.
