Description
Technical field
The utility model relates to a kind of system of condition monitoring, belongs to the watch-dog technical field.
Background technology
At present the plant equipment in a lot of industry long-time running imbalance often occurs, the mechanical fault such as misaligns, and also may cause the interruption of whole equipment to stop when serious, even may produce personal injury.Classic method is exactly the meticulous maintenance of dependence maintainer and work on the spot experience, observes and find.Meticulous maintenance can well improve the serviceable life of engineering goods, but but can not definitely avoid the generation of fault; The omen of all mechanical equipment faults is exactly generally the abnormal vibrations of sports equipment, can effectively predict the appearance of fault by the monitoring to vibration.In case scent a hidden danger, just can check at any time, prevent the fault extension, elimination accident in advance.Present vibration monitoring method is mainly to adopt hand-held vibration logging artificially to monitor.The monitoring people vibrates logging by hand-held and detects the vibration parameters of each point, thereby judges whether to exist potential safety hazard.The shortcoming of this mode is to realize on line real-time monitoring,, for some industrial occasions higher to security requirement, can stay the potential safety hazard that unit exception can not in time be found, and needs to drop into very large manpower.
In view of above-mentioned ubiquitous defect, can design, produce a kind of novel vibration monitor system,, to make up above-mentioned defect, be the technical barrier that those skilled in the art face.
Summary of the invention
The utility model aims to provide a kind of system of condition monitoring, and it has overcome the drawback of existing vibration monitoring method, can real time on-line monitoring, use manpower and material resources sparingly etc.Its technical scheme that adopts is as follows: this system of condition monitoring comprises sensor, gauge internal processing integrated unit, tele-control system, wherein, gauge internal processing integrated unit comprises signal acquisition and processing system, A/D converter, numerical display device and relay output-controlling device; Signal acquisition and processing system is connected by stube cable with sensor, and signal acquisition and processing system is connected with tele-control system, and A/D converter is connected with signal acquisition and processing system, numerical display device and relay output-controlling device respectively.
Preferably, gauge internal processing integrated unit is single-chip microcomputer or DSP unit.
Preferably, numerical display device is LED screen or charactron.
The utility model advantage compared to prior art is: 1, can realize on line real-time monitoring, automatically carry out the storage of Monitoring Data; 2, use manpower and material resources sparingly, reduce the cost of long-term monitoring.

Symbol description: 10, sensor; 20, stube cable; 30, gauge internal is processed integrated unit; 40, tele-control system; 301, signal acquisition and processing system; 302, A/D converter; 303, numerical display device; 304, relay output-controlling device.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in Figure 1, this system of condition monitoring comprises sensor 10, gauge internal processing integrated unit 30, tele-control system 40, wherein, gauge internal processing integrated unit 30 comprises signal acquisition and processing system 301, A/D converter 302, numerical display device 303 and relay output-controlling device 304; Signal acquisition and processing system 301 is connected by stube cable 20 with sensor 10, signal acquisition and processing system 301 is connected with tele-control system 40, and A/D converter 302 is connected and is connected with the relay output-controlling device with signal acquisition and processing system 301, numerical display device 303 respectively.
Gauge internal is processed integrated unit 30, integrate various processing modules and circuit and output module, specifically comprise following content: signal acquisition and processing system 301, be preferably DSP unit or single-chip microcomputer, the original signal of the sensor 10 that reception stube cable 20 transmits, by its built-in circuit, signal is carried out the processing such as filtering, conditioning signal later is converted to multiple output form (as Buffer output, 4-20mA analog outputs etc.), signal analysis and processing, equipment state judgement and the maintenance etc. for other system provide basis.
A/D converter 302, be converted to digital quantity signal with analog signals, offers the protection of relay as equipment state.
Relay output-controlling device 304, receive the signal from A/D converter 302, and by signal comparator circuit and predetermined threshold value, compare, thereby pilot relay moves, and reaches the purpose of warning, jumping car.
Tele-control system 40, receive the signal of processing integrated unit 30 from gauge internal, remote monitoring opertaing device running status, and the various parameters of extraction equipment real time execution, facilitate customer analysis to process various parameters.
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
