Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
Embodiment 1
As it is shown in figure 1, a kind of wireless vibration measuring system, including vialog, described vialog includes vibration acceleration sensor, infrared
Temperature sensor, pt100 sensor, Laser Measuring speed probe, the single-chip microcomputer of super low-power consumption bluetooth 4.1 high-speed transfer chip,
Signals collecting and change-over circuit, it is exclusively used in 24 high-precision a/d converters of vibration measuring system composition, it is characterised in that: arrange by indigo plant
The transmission network of tooth module composition, arranges the high frequency transmitting-receiving electricity being connected by digital signal interface with single chip circuit in vialog
Road, high frequency transmission circuit includes RF transceiver and antenna.
Loopback network is by being placed at least one bluetooth module (being served as by PDA) in detection region and the multiple of management region
Bluetooth module forms, and bluetooth module includes miniature central processing element and the high frequency transmitting-receiving electricity supporting Bluetooth wireless communication agreement
RF transceiver that road is arranged equally and antenna, RF transceiver is by digital signal interface with miniature central processing element even
Connecing, the bluetooth module (PDA) in management region is connected with host computer by network or other modes.
So-called detection region, is i.e. to have at the vibration measuring work of one or above detection position, and bluetooth module is placed in detection
Near position, refer to laying or the explanation to be checked of other engineers and technicians delimitation of electronic tag.In view of work in reality
The situation that industry is patrolled and examined, management region is arranged on detection areas adjacent, if there being the distance of nearest network node to exceed the most as far as possible
10m, can re-start networking and arrange.Measure position specific address information, should be according to the actual range of Bluetooth transmission depending on, some
Under industrial environment, machine density is relatively small, and space is the most spacious, and the distance of Bluetooth transmission can not be affected by machine, so
Just can arrange some nodes more, use less PDA, reduce cost, decrease and search concrete measurement position according to memory
Trouble and inconvenience.
After PDA receives the data of bottom bluetooth module, it is transferred to host computer, is now checked data by inspection management personnel
And form, observed data, either with or without exception or beyond normal setting value, learns the quality of monitored equipment with this.
The antenna of high frequency transmission circuit uses Bluetooth antenna or built-in antenna.
This innovation has 2 points: first, is use bluetooth communication mode first, continuously transmits vibrational waveform data；
Second: be all to use the most ready-made wireless communication module in former industry, this is directly to use Bluetooth chip, has both controlled data
Gather, also use this chip to upload data, the power consumption of instrument is greatly reduced, improve the service life of battery, reduce
Area shared by chip.
The foregoing is only one embodiment of the present of invention, not in order to limit the present invention.Every the present invention's
Within spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
