摘要： A method of configuring and synchronizing a wireless machine monitoring system that has at least one chain, that includes at least one machine monitor and at least one repeater is disclosed. The wireless machine monitoring system may further include a master repeater that is in communication with the chain and a command station that is in communication with the master repeater. The wireless machine monitoring system is configured so that only one element of the system is communicating at any given time. In addition, bit error rate transmission tests are performed on the elements of the system to determine their ability to communicate at different transmission power levels. Thus, power consumption of battery powered elements is minimized by decreasing the amount of time the devices are active and by configuring the communicating elements to transmit at the lowest acceptable power level. An installation and configuration unit is provided for installing and configuring the machine monitors and the repeaters within each chain of the wireless machine monitoring system.

摘要： A wireless machine monitoring and communication system includes one or more machine monitors which attach to one or more machines to sense a physical characteristic of the machine, such as vibration or temperature, and to produce wireless transmissions corresponding to the sensed characteristic. A command station executes machine status polling in accordance with a time-division communication protocol and processes machine status data obtained during polling to determine the status of the machine. The machine monitor incorporates a wireless transmitter for transmitting at least status information, and the command station incorporates a wireless receiver for receiving monitor transmissions. To conserve power, the machine monitors are turned on only at preprogrammed times in accordance with the time-division communication protocol. Each machine monitor includes a receiver and the command station includes a transmitter to enable the command station to send commands to each machine monitor. A microcomputer in each monitor analyzes sensor data and a memory stores the analyzed sensor data. Repeaters are employed as necessary to assist in propagating wireless transmissions throughout the system. A tachometer sensor is employed at each machine to provide monitors and sensors with information relating to machine speed. A computer network is connected to the command station for transferring data and for controlling the overall operation of the system.

摘要： An apparatus is disclosed consisting of one or more machine monitors which attach to one or more machines to sense a physical characteristic of the machine, such as vibration or temperature, and produce wireless transmissions corresponding to the sensed characteristic, and a command station which receives the transmissions from the machine monitors and processes the information to give an indication of the condition of the machine. The machine monitor incorporates a wireless transmitter to transmit the sensor data, and the command station incorporates a wireless receiver to receive the sensor data. In the preferred embodiment of the invention, the machine monitors are not continuously on, but turn on only at preprogrammed times according to turn-on commands generated by a timer circuit within each machine monitor. In another preferred embodiment, each machine monitor includes a receiver and the command station includes a transmitter to enable the command station to send commands to each machine monitor. Each machine monitor includes a microcomputer to analyze the sensor data and a memory to store the analyzed sensor data prior to transmission to the command station. A repeater receives the sensor data transmissions from the machine monitors and retransmits the data to the command station when, due to site conditions, the machine monitors are beyond the receiving range of, or out of the line of sight to the command station.

摘要： Power saving features are employed in a machine monitor to reduce electrical power consumption and increase the life of an electrical power source (such as a battery) which is used to power the monitor. The monitor includes a microcomputer having a high operating speed and a low operating speed. Power consumption is reduced by placing the microprocessor in a low-power sleep mode when full power capabilities of the microprocessor are not needed. Power consumption is further reduced by operating the microprocessor at the low operating speed when a high operating speed is not needed. The monitor also includes a communications port in electrical communication with the microcomputer for communicating with a peripheral device, and sensors for sensing machine characteristics such as speed, temperature, flux, or vibration. Power switches are employed to remove electrical power from portions of the monitor electronics that are not being used or are not needed, and a DC/DC converter maximizes the amount of electrical power available for use by the monitor electronics. Power consumption is further reduced by the manner in which the monitor processes vibration signals to compute machine speed.

摘要： A method for nonintrusive monitoring of slow speed machinery incorporates a high sensitivity accelerometer capable of detecting low level mechanical vibrations, and a standard data collector/analyzer for processing the accelerometer output in accordance with a slow speed technology (SST) methodology that is implemented by firmware or software. To prevent the high frequency components from overwhelming the low frequency components of the accelerometer output as a result of dynamic range loss during processing of the accelerometer output by the data collector/analyzer, the SST methodology converts the accelerometer output from the acceleration domain to the velocity domain with an analog integrator that amplifies the low frequency components of the accelerometer output while attenuating the high frequency components. The analog integrator distorts the low frequency vibration components as well as the electrical noise introduced by the accelerometer. The distorted signal is then digitized by an A/D converter and transformed to the frequency domain by means of a fast Fourier transform. Within the frequency domain, mechanical vibrations (significant peaks) are separated from the noise and other non-vibration induced transients by fitting the transformed data set to a threshold noise floor that is calculated based on a statistical variance of a most probable noise floor of the accelerometer. All peaks/amplitudes greater than the threshold noise floor are considered significant and retained as indicative of mechanical vibrations occurring within the machinery, while all peaks below the threshold noise floor are considered insignificant and eliminated from further consideration.
