Abstract

The invention relates to a modular data recording and display unit. A module (4) essentially comprises a sensor (5), a controller (10) and a memory (11). The controller (10) processed the data recorded and transmitted by the sensor (5) and records the same in the memory (11). One or several types of sensors (5) may be connected depending on the module (4), for example with differing measuring ranges or differing measuring parameters. The multiplicity of connection possibilities and data formats can make the provision of further components, such as transmitter (6), receiver (7), amplifier (8) and converter (9) necessary between a sensor (5) and a controller (10). The controller (10) for the module (4) is configured and controlled by means of a control bus (12). The measured data stored in the memory (11) are read off using a separate data bus (13).

Claims

1. A data recording and display unit (1) that can be connected

for data exchange by means of a communications controller (23) and a signal converter (24) to a serial or parallel interface (25) of a computer (21), consisting of various units (3) and a basic unit (2), which are connected to each other by a control bus (12) and a data bus (13), and are synchronised by means of a single real time clock (20) on the basic unit, and of at least one module (4) which

comprises at least a sensor (5), a controller (10) and a memory (11) for recording and storing data,

optionally may have a transmitter and receiver, amplifier, converter or combinations thereof between sensor (5) and controller (10),

stores in its memory (11) each measuring point together with the clear time of the measurement generated by the real time clock (2),

characterised in that

even without an exchange of modules many sensor combinations are made possible by connecting different combinations of sensors to a module,

the modules (4) themselves record the sensor combinations connected to them by carrying out a setup routine after the unit (1) is switched on,

the configuration data for the individual sensors (5) remain stored to enable sensors (5) already configured to be connected or omitted without this necessitating a reconfiguration on the PC (21).

2. The data recording and display unit (1) according to claim 1, characterised in that

commercially available measuring instruments can be incorporated in the same way as sensors by means of special modules, and supply measured values synchronised by this method of incorporation with the other modules installed.

3. The data recording and display unit (1) according to claim 1, characterised in that

the control bus (12) connects the controller (22) to the communications controller (23) and the controllers (10) on the basic unit (2) and the units (3),

a data bus connects all the memories (11) on the basic unit (2) and the units (3) directly to the communications controller (23).

4. The data recording and display unit (1) according to claim 3, characterised in that a module (4) is present on the basic (2) for measuring each of the following:

triaxial accelerations, pressure and temperature.

5. The data recording and display unit (1) according to claim 1, characterised in that any module (4), for example a transmitter module, is able to take over control of the control bus, wholly or in part (Multi-master operation).

6. The data recording and display unit (1) according to claim 5, characterised in that

a transmitter module is able to read the measured data via the data bus (13) and transmit the data to a computer (21),

the transmission method (WLAN, Bluetooth, radio, etc.) can be freely selected by means of corresponding modules.

7. The data recording and display unit (1) according to claim 4, characterised in that

the basic unit is installed in an easy to handle housing (26),

the display module (17) and the control elements (18) of the basic unit (2) are also integrated in the housing (26),

a plug connection is integrated in the housing (26) so that further units may be connected.

8. The data recording and display unit (1) according to claim 3, characterised in that a plurality of plug connections (14) is installed on a base plate (29), into which connections the basic unit (2) and units (3) may be inserted for fixing and for connecting to control bus (12) and data bus (13).

9. The data recording and display unit (1) according to claim 6 and any one of claims 5 or 6, characterised in that it can record data from a motor vehicle or aircraft.

10. The data recording and display unit (1) according to claim 6 any one of claims 5 or 6, characterised in that it can record medical and/or sports medical data.

11. The data recording and display unit (1) according to claim 1, characterised in that the memories (11) of the modules (4) are divided into pages (42), which in turn each consist of a header (43) and a data area (44), in that configuration data from a measurement are stored in the header (43) and the measured data together with the times of the measurement are stored in the data area (44), so that the measurement can only be reproduced from the data in the memories (11).

12. The data recording and display unit (1) according to claim 1, characterised in that the modules (4) are able to withstand major force and heat influences without damage due to a special method of construction, for example casting in resin and equipping with ceramic heat shields.

13. A control program for a data recording and display unit (1) according to any one of the preceding claims, which unit comprises the network ready components setup, reader, viewer and online, characterised in that

the online component enables the measured data from all the sensors to be displayed in parallel in real time on the PC (21) both as raw data and graphically,

the user surface on the PC (21) is automatically adapted so that for the modules (4) and sensors (5) recorded by the setup component a graphic interface is made available for the configuration of the same, and so that only the components that are actually connected can be configured.
