Abstract
一种监听机械设备内部运行声音是否正常的监听装置。其感应头主要由振动传感器(9)、磁座(10)和永久磁铁(11)构成,永久磁铁(11)安装在磁座(10)下面的安装孔内,振动传感器(9)安装在磁座(10)上面,传感器(9)的信号输出端(7)经放大器与计算机的信号输入端相连接,计算机的多媒体声卡连接着其外部的音箱和/或耳机。该装置即可对设备进行实时监听,又可记录设备发出的声音,也可插放设备的历史声音来进行对照比较,能很方便地对设备运行中人无法靠近的地方进行监听。
The utility model relates to a monitoring device for monitoring whether the internal running sound of mechanical equipment is normal. The induction head is mainly composed of a vibration sensor (9), a magnetic base (10) and a permanent magnet (11), the permanent magnet (11) is installed in the mounting hole under the magnetic base (10), and the vibration sensor (9) is installed in the magnetic base (10). On the seat (10), the signal output terminal (7) of the sensor (9) is connected to the signal input terminal of the computer through the amplifier, and the multimedia sound card of the computer is connected to its external sound box and/or earphone. The device can monitor the equipment in real time, record the sound from the equipment, and can also insert and play the historical sound of the equipment for comparison, and can conveniently monitor the places where people cannot approach the equipment during operation.
Description
The utility model relates to a kind of equipment monitoring device, and normally whether specifically a kind of monitoring plant equipment internal operation sound device.
Chinese patent ZL96202848.7 discloses a kind of " the device interior sound is listened to device ", it comprises two earplugs, earplug bar, flexible rubber hose, three-way pipe etc., the three-way pipe bottom links to each other with inductive head through gas bag, scalable audition pipe, the endoporus that one diameter, 3～10mm is arranged in the inductive head, inductive head end are metal induction barrier film.During use, after the sound of being monitored vibrated by barrier film, the audition pipe, the gas bag that reach hollow through endoporus imported in operator's the ears after amplifying.This listens to the monitoring of device ears can avoid environmental interference, and the susceptibility height is simple in structure, easy to carry.Existing problem is: can only real-time listening; During to equipment operation, the place that the people can not or can't be approaching can't be used.
The purpose of this utility model provides a kind of equipment monitoring device, can carry out real-time listening to equipment, but the sound that sends of recording unit again also can be had access to the voice history of arbitrary time device and compare with sound in real time; And can be to equipment operation the time, the staff can't monitor in close place.
The purpose of this utility model is to realize like this.
A kind of equipment monitoring device, have inductive head, earphone, inductive head mainly is made of vibration transducer, magnetic support and permanent magnet, permanent magnet is installed in the mounting hole below the magnetic support, vibration transducer is installed in above the magnetic support, the signal output part of vibration transducer is connected with the signal input part of computing machine through amplifier, and the multimedia sound card of computing machine is connecting its outside audio amplifier and/or earphone.
Vibration transducer has the protective sleeve that an end is connected with magnetic support outward, is not subjected to the erosion of oil, water etc. in order to the protection sensor.
One aluminium matter inner ring is arranged in the mounting hole below the magnetic support, and permanent magnet is installed in the aluminium matter inner ring, to prevent the magnetic circuit closure, increases magnetism intensity.
There is the red copper covering of a covering permanent magnet magnetic support bottom, gives birth to elegant to prevent permanent magnet.
The advantage that the utility model is compared with prior art had is: because the employing of multimedia computer not only can be carried out real-time listening to equipment, and can carry out record, and have access to the voice history of arbitrary time and sound contrast in real time at any time to the sound of equipment.Convenient especially under the more situation of measuring point, not only can carry out real-time listening to the sound of each measuring point of equipment, can also carry out various time and frequency domain analysis to vibration signal.The use of this equipment has realized remote monitoring, not disturbed by site environment, monitors effective.To staff in the equipment operation can't be close the place, can monitor, and the measuring point accurate positioning handling safety easily.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of the utility model equipment monitoring device.
Fig. 2 is the structural representation of inductive head among Fig. 1.
The utility model as shown in Figure 1, mainly is made up of inductive head 2, amplifier 3, computing machine 4, audio amplifier 5 and earphone 6.Inductive head is seen Fig. 2, mainly by protective sleeve 8, vibration transducer 9, magnetic support 10, permanent magnet 11, and compositions such as red copper covering 13 and aluminium matter inner ring 14.In the mounting hole below the magnetic support 10 an aluminium matter inner ring 14 is housed, permanent magnet 11 is installed in the aluminium matter inner ring 14.Magnetic support 10 bottoms have one by being enclosed within the red copper covering 13 in order to covering permanent magnet 11 that magnetic support 10 outer trim rings 12 install and fix.Vibration transducer 9 be installed in magnetic support 10 above, it is outer to have a protective sleeve 8 that is connected with magnetic support 10 upper end screw threads, and the glue of sealing band 15 is arranged between the connecting thread of magnetic support 10 and protective sleeve 8.The signal output part 7 of vibration transducer 9 is connected through the signal input part of amplifier 3 with computing machine 4, and the multimedia sound card of computing machine 4 is connecting its outside audio amplifier 5 and earphone 6.Between the signal output part of vibration transducer 9 and the amplifier 3, between the signal input part of amplifier 3 and computing machine 4, and all be connected between the multimedia sound card of computing machine 4 and audio amplifier 5, the earphone 6 by cable.
During work, inductive head 2 is fixed on the listening point of equipment 1 by its permanent magnet 11, the signal that 3 pairs of vibration transducers of amplifier 9 are gathered amplifies, the signal input computing machine 4 after the amplification, and computing machine 4 gets off the equipment SoundRec by its multimedia sound card or A/D sampling.Simultaneously, the staff can carry out real-time listening by the sound equipment 5 that is connected with multimedia sound card in the computing machine 4 and the sound of 6 pairs of equipment 1 of earphone, also can play the voice history that is stored in the equipment on computing machine 4 hard disks or the CD etc., come to compare contrast with real-time sound.
