The present invention can according to the difference of monitoring equipment type, it is divided into the trigger collection that several operating mode carries out valid data according to rotating speed, and the switching by vibration total value, the acquisition mode measuring the difference vibration data such as definition of data, long wave graphic data, equipment well can be monitored, the power consumption of whole system can be made again to be well controlled simultaneously. In order to better allow the collecting transmitter of unstable state device data effectively be monitored by equipment, when equipment normal operation, only gather measurement definition of data and the long wave graphic data of vibration total value and longer cycle; Constantly increase when monitoring vibration equipment total value, when equipment may break down, then trigger the collection density reported to the police and increase and measure definition of data and long wave graphic data. By these acquisition strategies and strategy of reporting to the police, when meeting diagnosis of equipment, reduce unnecessary redundant data as far as possible, reduce the power consumption of device.
Unstable state device type is various, different equipment operation conditions is also different, just there is larger difference in the equipment service performances such as such as milling train, lift and gas blower, the wireless monitor strategy of these equipment some be also in the stage of fumbling, when gathering the device data that some do not have ripe monitoring scheme, just need the data results according to monitoring, correction acquisition strategies of constantly summarizing, thus formed the good monitoring scheme of this kind equipment. The mode of 3G is adopted to carry out data transmission control between wireless collection station and remote data server, so that it may well to realize these requirements. When we need the data type adjusting collection period or monitoring, directly can first carry out relevant setting on remote data server, at the end of wireless collection station one-period gathers, inquiry service device determines whether the acquisition strategies in next cycle changes, if change, obtain new acquisition strategies, then reconfigure collection period and the Information Monitoring of wireless tachogenerator and wireless vibration sensor, just can reach good interactive controlling by the time delay of maximum one-period like this and realize new data collection strategy.
