Abstract
The utility model relates to a vibration detection analysis meter. The vibration detection analysis meter comprises a vibration sensor for detecting a device; the vibration sensor transmits a detection signal to a signal conditioner; the signal conditioner is used for conditioning and then transmitting the detection signal to a signal collector; the signal collector transmits the collected detection signal to a CPU (Central Processing Unit); the CPU exchanges data with a WWW server connected with a lower computer; and the CPU sends an alarm signal to an alarm device. The vibration detection analysis meter can execute data filter of the vibration detection signal, select signal frequency bands without changing a hardware circuit, and achieve a large amount of local storage, avoid loss of data under a condition of disconnection; large amount storage of the server provides an ample data source for device operation trend and failure analysis; online data computing and analysis and professor failure alarm prompt a client to execute device maintenance, servicing or shutdown, so as to enable the device to efficiently operate or lower the loss to the lowest.
Description
Technical field
The utility model relates to the vibration detection analyser.
Background technology
In plant equipment; Vibration is an important technical parameter; Often need monitor the stationarity of equipment in motion process; And compare through the mechanical parameter of detected vibration signal and design, reflect the operation conditions of equipment in real time, for the safe and highly efficient operation of equipment escorts.
At present, common on the market detection vibratory equipment has two kinds: a kind of is just data acquisition to be carried out in vibration, then the data that collect is carried out manual analysis; With the operation conditions of this judgment device, this just vibration acquisition appearance is not reported to the police; Do not analyze; Can not vibration trend be represented, can not tell the variation tendency of vibration equipment, belong to simple and easy non intelligent manual detection equipment; Another kind is the Fourier transform etc. that on preceding a kind of basis, has increased data, can see variation tendency and frequency content thereof, but can not intelligent alarm with point out the trouble spot, still want manual work to analyze summary at last, time-consuming, effort, non real-time.
The utility model content
To above-mentioned technical matters, the utility model provides the vibration detection analyser of a kind of monitoring in real time, computational analysis, Realtime Alerts.
The utility model solves the problems of the technologies described above and adopts technical scheme to be: a kind of vibration detection analyser; Comprise the vibration transducer that equipment is detected; This vibration transducer is delivered to signal conditioner with detection signal, and this signal conditioner is passed to signal picker after signal is nursed one's health, this signal picker with the signal conveys of gathering to CPU; A CPU and a Web server carry out exchanges data, and this server is connected with slave computer.
The utility model also has following additional technical feature:
Said CPU sends alerting signal to panalarm.
Said CUP is connected with the CAN communication interface.
Said CUP is connected with the RS232 communication interface.
Said CUP is connected with switching value input and switching value output.
The utlity model has following advantage:
1, can carry out data filtering to vibration detection signal, under the situation that does not change hardware circuit, the signal frequency range selected;
But the local storage of 2 high capacity, assurance data broken string is not lost, and the storage of server high capacity is for running trend of the equipment, fault analysis provide sufficient Data Source;
3, online data computational analysis, expert's fault alarm real-time reminding client carry out corrective maintenance, maintenance or stoppage in transit, let the running of equipment high efficiency rate perhaps drop to minimum to loss.
Description of drawings
Fig. 1 is the theory diagram of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Below in conjunction with Fig. 1 to Fig. 2 the utility model is done to specify further:
This vibration check and analysis appearance comprises the vibration transducer 1 that equipment is detected; This vibration transducer is delivered to signal conditioner 2 with detection signal, and the signal conditioning circuit of signal conditioner is that vibration transducer provides power supply, and signal conditioner carries out multistage high pass, LPF to the signal of vibration transducer output; Remove undesired signal; Stay useful signal, it can be selected the signal frequency range under the situation that does not change hardware circuit data filtering; Signal conditioner is passed to signal picker 3 with useful signal, and collector is gathered this signal in real time, and the collector figure place can be up to 24; The single channel collection can be up to 400k/s, and to CPU4, CPU carries out the scalar conversion to the signal that collects to this signal picker with the signal conveys of gathering; And send to Web server 5 to raw data, by server signal is carried out signal Processing, according to specific calculations to bearing, fan blade, tower body etc.; Combine the empirical data of experts database that monitored object is carried out comprehensive assessment then; Provide the corresponding report of the operation health status of monitored object in real time,, then the maintenance position is provided suggestion as producing fault; CPU also calculates vibration values in real time, and the peak value of live signal, effective value etc. are calculated, and then reports to the police to panalarm 7 output alarm signals through relay if any exceeding standard.Said Web server 5 is connected with slave computer 6, has the raw data memory space of 2GB during the slave computer off-line, obliterated data not when guaranteeing to go offline.
In implementation process; Vibration transducer is passed to CPU with detected high precision vibration signal, and uses and to send to Web server based on the tcp/ip communication agreement, breaks off like server; Slave computer is with the data-storing that collects; Again the data upload of storage, guaranteed the continuity of data like this when server connects by the time, for running trend of the equipment, fault analysis provide sufficient Data Source.Because the server of the utility model adopts Web server; The client can inquire about data in server through client; The ruuning situation of remote supervisory equipment, the maintenance cost that significantly reduces like this lets the running of equipment high efficiency rate perhaps drop to minimum to loss.The utility model can also import 8 through switching value, switching value output 9, RS232 communication interface 10, CAN communication interface 11 etc. are carried out message exchange with third party device, and third party device can be monitored accordingly.
In the utility model, after the signal condition unit UNIT1 of the detection signal process signal conditioner that vibration transducer detects carried out the signal filtering amplification, the collecting unit UNIT7 that delivers to signal picker gathered; The CPU UNIT4 that UNIT7 delivers to CPU with the signal in real time that collects handles; Through signal processing means such as digital filtering, Fourier transform to signal handle, conversion, screening; And result and alarming value, dangerous values compared; In case of necessity through switching value output unit UNIT6 output alarm danger signal, simultaneously, UNIT4 can be CPU etc. required power supply is provided; After UNIT4 handles, obtain desired result of oscillation and can also export to third party device through current transformation unit UNIT2; The user carries out release, resets alerting signal through switching value input block UNIT5 according to need.The utility model can be used for the vibration situation and the Realtime Alerts of industrial occasions measuring equipment, reaches the effect of measuring and protecting.
Above-mentioned embodiment only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to the scope of the utility model.
