Description

TECHNICAL FIELD

The present invention relates in general to handheld test and measurement devices and more particularly to a portable device that combines both a data collector and analyzer for monitoring machine systems and detecting machine fault conditions.

BACKGROUND ART

Prior art handheld data collector and analyzer devices are generally used to collect vibration measurements from machines or systems for use in predicting maintenance applications. Data collectors use different measurement routines depending on the type of machines or systems, measurement sensors, test points, and set-up conditions for each test point. Typically, based on inputs from the user, the handheld device prompts the user as to the identity of the machine and the test point to be monitored, and automatically sets up the device, for example to record a particular measurement parameter and range for a given test point, conduct a predetermined analysis and store a predetermined set of data. The analyzer uses different software routines based on the previous types of machines or systems chosen and determines for each test point what type of analysis needs to be performed, a particular type or set of data to be stored, and similar other parameters to be analyzed.

However, the above described hand held data collector and analyzer devices and associated measurement techniques have been developed for the collection and data for machines and systems used for a particular industry or sensor application. Furthermore, the resulting analyzed data is only available to the user in limited display formats. Therefore, a need exists for a data collector and analyzer device that can receive the input provided from any signal or sensor data for any machine or system used in any industry and that can display the processed data on any display format that the user chooses.

SUMMARY OF THE INVENTION

A handheld measurement device incorporating both a data collector and an analyzer is disclosed. The data collector of the device receives one or more external input signals and stores the data collected for later retrieval and analysis. In one embodiment these input signals are received from sensors for example vibration sensors used to collect vibration measurements in machine systems for predictive maintenance purposes. The analyzer using software routines in accordance with a method of the present invention retrieves and processes the collected data using filtering techniques associated with the sensors and machine system being measured and performs calculations that determine the absence or presence of a machine system defect. Additionally, the handheld measurement device includes a display for providing a user with one or more different visual presentations of the calculated results with respect to the collected measured data or alternatively provides the user the option of transferring the calculated results either directly or wirelessly to the display used with any other computer system.

While the preferred embodiment is described herein in connection with vibration, other embodiments of the invention measure other operational parameters of machine systems such as for example, but without limitation, voltage, current, flux, temperature, pressure, force, speed, displacement, energy, color, frequency, etc.

Although not shown in FIG. 1, the device 10 is designed to electrically receive one or more analog inputs. By way of example only, the device 10 may provide from four to eight single-ended analog inputs using digital counters, TTL-level digital-switch input lines, and TTL-level digital-switch output lines. Furthermore, the device 10 houses a graphical digital display screen 12 shown by way of example located at the top area of device 10 for allowing a user (not shown) to view data results. In this example, the lower area of device 10 shows menu selection buttons 14 that in association with the display screen 12 that allows a user to interface and control different software features offered by the device 10 in addition to viewing the data results.

Referring now to FIG. 2, there is shown a block diagram illustrating one example of the types of different electrical and software modules and external hardware that when interconnected in electrical communication 26 to each other result in an electronic system that maybe is used for the handheld data collector and analyzer in accordance with the present invention. As shown in FIG. 2, the primary modules used in one data collector and analyzer of the present invention comprises a master module 20 having an associated slave module 22. Turning once again to FIG. 2, the master 20 and slave 22 provide as many analog channels or electrical interface connections as needed to perform a specific test. In the example shown in FIG. 2, there are shown 4 analog channels which is by way of example only and not of limitation a typical four (4) channel multi-meter (not shown.

Referring once again to FIG. 2 the master and slave modules 20 and 22 respectively receive analog input signals from measurement sensors (not shown) which are then processed by digital block filters 28 which in turn are cached by external memory 30 and sent to transform processor 32 that performs the required data calculation depending on the machine or system under test to produce data analysis end results requested by the user at the beginning of a test measurement sequence. The transform processor 32 then sends this data to display processing modules 34 that assist in formatting the data results send to an input/output bus line 36 for delivering the data results to one or more selected display's 38 chosen by the user at the beginning of a test sequence. Lastly, there is shown a USB protocol subsystem 40 for delivering these same results directly or wirelessly in real time to one or more USB ported devices 42 or any system 44 such as a desktop or laptop which has a display screen having an HTML browser.
