The basic measurement principle of the vibration sensor is that the mechanical displacement (displacement, speed and acceleration) of the equipment is recorded through magnetoelectric induction, converted into an electric signal and amplified to be displayed. Existing vibration sensors are generally classified into contact type and non-contact type: the non-contact vibration sensor mainly uses ultrasonic waves and laser, has a single measuring mode and is often applied to scientific research. The touch sensor has mature technology and high stability, and is a mainstream product, such as a common touch sensor of a power system.
The following problems mainly exist in the current inspection work: 1) the polling personnel need to carry various measuring devices such as a temperature measuring instrument, a vibration measuring instrument and the like when polling work is carried out each time; 2) the portable vibration measuring instrument commonly used by inspection personnel is usually a contact type vibration measuring sensor. The measuring mode is that the measuring probe, the magnetic seat and the like are contacted or attracted to the non-rotating positions such as the bearing seat and the like of the tested equipment. During mobile measurement, the vibration measurement sensor needs to be manually disassembled and assembled. When the vibration measurement sensor is installed or disassembled on the rotating equipment, the risk brought by the personal injury of the rotating equipment must be prevented. And the contact type vibration measurement sensor has poor high temperature resistance, and the influence caused by higher temperature change can possibly cause the failure or damage of the probe. 3) The portable vibration measuring instrument commonly used by inspection personnel is characterized in that a vibration signal and a phase signal which are measured by the portable vibration measuring instrument are respectively arranged and installed by two devices, and the vibration phase can not be visually displayed; 4) the contact vibration measurement sensor commonly used by inspection personnel can only measure the vibration of the bearing seat, and the vibration condition of the rotating shaft can not be directly and effectively measured.
