Definitions
- the invention relates to a measuring arrangement with several identical digital storage oscilloscopes.
- the handheld measuring device 20 has on the outside of its handy pin housing 21 a measuring tip 22 , the signals of which can be further processed and displayed in the handheld measuring device 20 itself.
- the signals of the measuring tip 22, amplified by means of an amplifier 23 are fed to a control device (CPU) 24 , which controls the recording and output of the measurement data.
- the measurement data are then either directly displayed on an LCD display 25 on the handheld measuring device 20 or forwarded to a data processing unit 26 (for example a PC, palmtop or laptop).
- the handheld measuring device 20 has an RS232 interface 27 , which is connected to the serial interface 29 of the data processing unit 26 via a cable 28 .
- JP-A-59165545 discloses a measuring arrangement which a synchronized measurement recording of all devices. The synchronization assumes a certain device, the "master”.
- the advantage of this measure is that the handheld measuring devices for the master operation and the handheld measuring devices for the Slave operation can be constructed identically. By short The operator can operate the one that is cheapest for him Handheld devices, e.g. the nearest handheld meter, Select as master device and there also the measurement data of the other handheld measuring devices operated as slave devices to let.
- this is Control signal transmitted wirelessly, in high frequency GHz range, so that's generally just a single bit comprehensive control signal to everyone with as little delay as possible other handheld measuring devices is sent. Wiring the individual handheld measuring devices with each other is therefore not necessary.
- the measurement data all handheld measuring devices to a central data processing unit, in particular transmitted wirelessly, in which the measurement data processed and then displayed centrally.
- the Data processing unit can either be an external data processing unit, such as. a PC, or in the master device be integrated. For this purpose, the measurement data of all other handheld measuring devices to the master device.
- the measurement data can be sent from the master device to the slave devices transmitted over cable, but it is special Advantage, the measurement data wirelessly to the central data processing unit to send for further processing. A Cabling of the handheld measuring devices with each other is therefore not required.
- Master device is connected to the central data processing unit operated control device a receiver to receive the others operated by the slave devices Measurement data transmitted to handheld measuring devices.
- the master device can thus evaluate the measurement data of all handheld devices and the operator on one of the control device Show controlled display. This can either be an ad of the master device or a separate one connected to it Display part can be used.
- the transmitter (s) and / or the receiver in a replaceable radio interface module are provided.
- This modular structure of the The operator can do this on site as required use a suitable module.
- the measuring device 1 shown in Fig. 1 comprises a plurality of identically constructed portable instruments 2 in the form of microprocessor-controlled digital storage.
- Each handheld measuring device 2 has on the outside of its handy pin housing 3 a measuring tip 4 , the signals of which can be further processed and displayed in the handheld measuring device 2.
- the signals of the measuring tip 4 amplified by means of an amplifier 5 are fed to a control device (CPU) 6 , which controls the recording and output of the measurement data.
- CPU control device
- These measurement data can then either be directly displayed on an LCD display 7 of the handheld measuring device 2 or forwarded to a data processing unit.
- a radio interface 8 with transmitter and receiver is provided in the handheld measuring device 2 and connected to the control device 6 in order to enable data exchange with other handheld measuring devices 2 and / or with a stationary or mobile data processing unit 9 (for example PC, palmtop or laptop etc.).
- a corresponding radio interface 10 with transmitter and receiver is provided in the data processing unit 9.
- the radio interface 8 of the handheld measuring device 2 is interchangeable Module designed to be used against other modules, e.g. against an RS232 interface module.
- the upper hand-held measuring device 2 is operated as a master device and all other hand-held measuring devices 2 are operated as slave devices which are controlled by the master device.
- a central control signal 11 is generated in the control device 6 of the master device, which is sent wirelessly via the radio interface 8 to all handheld measuring devices 2 operated as slave devices.
- the control signal which comprises only a single bit, is transmitted in the high-frequency GHz range and serves as a start signal for all handheld measuring devices 2 in order to start the measurement recording synchronously.
- the measurement recording in the master device also begins, so that all the handheld measuring devices 2 are synchronized with one another by the central control signal 11.
- the respective measurement data are transmitted wirelessly via the radio interfaces 8 of the individual handheld measuring devices 2 as radio data 12 to the radio interface 10 of the data processing unit 9.
- all slave devices can transmit your measurement data to the master device, whose control device 6 then evaluate all measurement data and on a display connected to the master device can.
- the LCD display 7 of the master device or a separate display part connected to it be used. So the master device is used as a data processing unit used.
- each handheld measuring device 2 There is a switch (not shown) on each handheld measuring device 2 provided to operate it either on the master or the slave adjust.
- the switch is preferably a button, so that the respective hand-held device can be operated by briefly pressing it 2 can be set as the master device.
- Fig. 1 arrangement can be the operator, after all Handheld measuring devices 2 are connected to their measuring points, then a desired one by briefly pressing the button Select handheld meter 2 as the master device.
