Description
Technical Field
The utility model relates to a vibration monitoring system, in particular to a vibration acquisition device for an inspection type vibration monitoring system.
Background
The vibration acquisition device is an important instrument for acquiring vibration of various objects, the conventional vibration acquisition device comprises a shell, a vibration measurement element, a data conversion circuit board, a power supply module, a communication module and other elements which are assembled together, the data acquisition in the prior art is generally divided into two types, the first type is used for fixing a sensor at a detection point position, and the detection data is uploaded by a data line; the second kind adopts the mode of artifical patrolling and examining to go on, and the handheld equipment of patrolling and examining personnel monitors to the check point.
When the first mode is adopted, the sensor needs to be powered by a battery or an external power supply; when the battery is used for supplying power, the battery capacity is generally low due to the limitation of the volume of the sensor in power supply, and the sensor powered by the battery cannot be applied to occasions requiring long-time continuous detection. And the vibration sensor of external power supply not only need be in the working condition wiring, and the operation is inconvenient, and the occasion that does not have external power supply in addition can't be suitable for again, and sensor data upload in addition needs to carry out the wiring processing equally, causes the phenomenon to be mixed and disorderly, and the sensor is in operating condition all the time moreover, causes a large amount of electric energy waste phenomenon.
In addition, in the prior art, as CN210922829U discloses a dual-mode power supply vibration sensor with a built-in antenna, the dual-mode power supply vibration sensor includes a casing having a cavity therein, a main board is disposed in the casing, the main board is connected to a communication board and a vibration sensing chip, a wireless antenna is disposed on the communication board and is close to the top of the casing, and the main board is connected to a storage battery and an external power connector for supplying power to the wireless antenna. This scheme design is exquisite, moreover, the steam generator is simple in structure, through setting up battery and external power source interface, when external power source, can connect external power source through external power source interface and supply power, when not having external power source, can supply power as reserve battery with the battery, make the vibration sensor integrate two kinds of power supply modes, thereby can effectually satisfy the use needs of different application occasions, use in a flexible way, it has disclosed that the vibration sensor can carry out wireless charging, but only richened to the mode of charging of vibration sensor, but the vibration sensor is in the open mode all the time, therefore the vibration sensor is in the power consumption state always, the wasting of resources has been caused widely.
When patrolling and examining about the mode of adopting artifical handheld patrolling and examining, the sensor setting is on patrolling and examining equipment, and the personnel of patrolling and examining are close to the check point and detect, though need not to carry out wiring etc. when the manual work is patrolled and examined, the hand slight shake of the hand that the personnel of patrolling and examining equipment can't avoid the human body can cause the low frequency signal to filter, causes the not accurate phenomenon of monitoring.
In addition, the inspection mode cannot objectively and conveniently master the in-place condition of inspection personnel, so that inspection personnel cannot effectively perform inspection according to plan requirements, and the authenticity of inspection data obtained by inspection cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, and provides a vibration acquisition device for an inspection type vibration monitoring system, which can monitor vibration signals generated in the operation of power equipment and has reliable laboratory performance and field monitoring function.
In order to realize the technical effects, the technical scheme of the utility model is as follows: the utility model provides a vibration collection system for patrolling and examining formula vibration monitored control system, include the mounting panel, set up in measuring element on the mounting panel, be used for gathering measuring element's monitoring signal's high-speed collection chip, be used for the analog signal who gathers the chip collection at a high speed to turn into digital signal's treater, still set up on the mounting panel and be used for turning into the receiving coil of electric energy with the electromagnetic wave, receiving coil respectively with measuring element the treater looks electricity is connected.
In a further improvement, at least one end of the mounting plate is provided with a fastener for fixing the mounting plate.
In a further refinement, the fastener is a set screw.
In a further improvement, an RFID chip is arranged on the mounting plate.
The utility model has the advantages and beneficial effects that: the vibration sensor is charged wirelessly, when the position of the vibration sensor is not reached in the polling process, the vibration sensor is in a power-off energy-saving state, when the position is reached in the polling process, the polling device charges the vibration sensor, the vibration sensor is started to work, and meanwhile, a detection signal is transmitted to the polling device, so that the polling device sequentially charges the vibration sensor and receives the detection signal, the energy consumption of the vibration sensor is low in the process, the vibration sensor does not need to be powered all the time, an external power supply is not needed, and the inconvenience of wiring is reduced;
in addition, when the inspection equipment can wirelessly charge the vibration sensor, the distance between the inspection equipment and the vibration sensor is in an effective signal receiving distance, the measuring element is fixed at a detection point to avoid the problem of low-frequency signal filtering, and the detection data is transmitted by adopting digital signals, so that the inspection equipment receives detection signals which are accurate signals, and the number of the vibration collecting devices received by the inspection equipment and the working attitude of the inspection personnel can be objectively surfaced all the time with the preset number.
