Abstract
The utility model discloses a vibration detection apparatus possessing an anti-interference function. The vibration detection apparatus comprises a computer control system, a monitor, a photoelectric signal isolator, a pre-transmitter and a sensor for detecting vibration signals, wherein the sensor inputs the signals to the pre-transmitter, the pre-transmitter inputs the signals to the photoelectric signal isolator, the photoelectric signal isolator inputs the signals to the monitor, and the monitor inputs the signals to the computer control system; and the outside of the pre-transmitter is provided with a metal shielding case. With the metal shielding case disposed outside the pre-transmitter, the space coupling channel of the interference field is cut off or weakened, and the interference on the input and output signals of the pre-transmitter caused by external interference signals are substantially reduced. The photoelectric signal isolator has a strong anti-interference capacity, and thus the output signals exert no influence on the input end, the operation of the apparatus can work stably, and the influence of interference signals in the signal transmission process can be further reduced. And high detection precision and low fault ratio of the vibration detection apparatus can be guaranteed.
Description
Technical field
The utility model relates to a kind of hanging device, particularly a kind of Steel plate hoisting implement.
Background technology
Vibration monitoring device all is installed in many enterprises, and its primary structure comprises computer control system, monitor, normal signal isolator, preposition transmitter and sensor; But because the factor of installation environment; Vibration monitoring device receives the influence of undesired signal bigger; As: by the frequency electromagnetic waves space radiation towards periphery of generations such as various high frequencies, intermediate frequency generating means and various electric sparks; Form electromagnetic interference, various undesired signals can cause each monitoring device other fault of sum of errors to occur detecting.
Therefore need improve vibration detection device of the prior art, improving its antijamming capability, thereby improve its accuracy of detection and reduce its failure rate.
The utility model content
In view of this, the purpose of the utility model provides a kind of vibration detection device with anti-interference function, and it has multiple interference protection measure, can effectively eliminate the external electromagnetic radiation interference, guarantees that the vibration detection device accuracy of detection is high, failure rate is low.
The utlity model has the vibration detection device of anti-interference function; Comprise computer control system, monitor, photosignal isolator, preposition transmitter and be used to detect the sensor of vibration signal; Sensor is imported preposition transmitter with signal, and preposition transmitter is imported the photosignal isolator with signal, and the photosignal isolator is with signal Input Monitor Connector device; Monitor is imported computer control system with signal, and preposition transmitter is outside equipped with metal shielding.
Further, the cable jacket that connects preposition transmitter and sensor has the metallic shield pipe;
Further, said computer control system ground connection, said metal shielding ground connection.
The beneficial effect of the utility model: the vibration detection device that the utlity model has anti-interference function; Outside preposition transmitter, metal shielding is set; Cut off or weakened the space coupling channel of interference field, the external interference signals that weakens that can be very big causes interference to the input/output signal of preposition transmitter; Adopt the photosignal isolator to substitute normal signal isolator transmission signals simultaneously, photosignal isolator antijamming capability is strong, and the output signal does not have influence to input end, and working stability can further reduce the influence that signals transmission receives undesired signal; Can guarantee that the vibration detection device accuracy of detection is high, failure rate is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation that the utlity model has the vibration detection device of anti-interference function.
Embodiment
Fig. 1 is the structural representation that the utlity model has the vibration detection device of anti-interference function.
As shown in the figure; Present embodiment has the vibration detection device of anti-interference function, comprises computer control system 1, monitor 2, photosignal isolator 3, preposition transmitter 4 and is used to detect the sensor 5 of vibration signal, and sensor 5 is imported preposition transmitter 4 with signal; Preposition transmitter 4 is imported photosignal isolator 3 with signal; Photosignal isolator 3 is with signal Input Monitor Connector device 2, and monitor 2 is imported computer control system 1 with signal, and preposition transmitter 4 is outside equipped with metal shielding 6.
Present embodiment has the vibration detection device of anti-interference function; Outside preposition transmitter 4, metal shielding 6 is set; Cut off or weakened the space coupling channel of interference field, the external interference signals that weakens that can be very big causes interference to the input/output signal of preposition transmitter 4; Adopt photosignal isolator 3 to substitute normal signal isolator transmission signals simultaneously, photosignal isolator antijamming capability is strong, and the output signal does not have influence to input end, and working stability can further reduce the influence that signals transmission receives undesired signal; Can guarantee that the vibration detection device accuracy of detection is high, failure rate is low.
As the improvement to this embodiment, the cable jacket that connects preposition transmitter 4 and sensor 5 has metallic shield pipe 7, can further stop the interference of external interference signals to the output signal of sensor 5.
As improvement to this embodiment, said computer control system 1 ground connection, said metal shielding 6 ground connection, grounding specifications, the ground connection link is few in the vibration detection device, has eliminated the multipoint earthing interference that transmission causes to signal.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
