Abstract

The invention relates to a method for controlling or regulating the energy flow in a measuring system which can be composed of a plurality of individual modules. Part or all of said individual modules are respectively connected by means of at least one energy supply line and at least one data line. At least one of said individual modules comprises an interface via which energy can be supplied. An energy balance table is created in at least one individual module on the basis of energy data from the connected individual modules. The energy supply and/or energy removal to/from the individual modules are controlled or regulated according to the data stored in the energy balance table.

Claims

1. A method of controlling or regulating the power flow in a measuring system (100, 101) composed of a plurality of intermateable individual modules (1, 11, 21, 31, 41), part or all of these individual modules (1, 11, 21, 31, 41) being connected via at least one power supply line (19, 29, 39, 49) and at least one data line (17, 27, 37, 47), at least one individual module (1, 31) of these individual modules having an interface (8, 18, 38) via which power is suppliable,

wherein a power balance table is prepared in at least one individual module (1) based on power data from the connected individual modules (1, 11, 21, 31, 41);

and the power supply and/or power consumption of the individual modules (1, 11, 21, 31, 41) is controlled or regulated based on the data stored in the power balance table.

2. The method as recited in claim 1,

wherein component-related data, permanently stored in a memory of an individual module (1, 11, 21, 31, 41), is used as power data.

3. The method as recited in claim 2,

wherein the nominal operating load data is used as component-related data.

4. The method as recited in claim 2 or 3,

wherein the standby and/or sleep-mode load operation data is used as component-related data.

5. The method as recited in one of claims 2 through 4, wherein the maximum load data is used as component-related data.

6. The method as recited in one of claims 2 through 5, wherein the closing load data and/or the change of state load data is used as component-related data.

7. The method as recited in one of the preceding claims, wherein dynamic operation data is used as power data.

8. The method as recited in claim 7,

wherein statistical data on the operating state of the connected individual modules (1, 11, 21, 31, 41) is used as dynamic operation data.

9. The method as recited in claim 8,

wherein data on the operating load, operating period or the like is used as statistical data on the operating state.

10. The method as recited in one of the preceding claims, wherein data on the charge state of a connected accumulator, of batteries or the like is used as dynamic operation data.

11. The method as recited in one of the preceding claims, wherein data determining a priority of the regulation or control of the power supply and/or the power consumption is used as dynamic operation data and/or component-related data.

12. The method as recited in one of the preceding claims, wherein the power balance table is created at the first start-up.

13. The method as recited in one of the preceding claims, wherein the power balance table is updated cyclically.

14. The method as recited in one of the preceding claims, wherein the power balance table is configured by the user.

15. The method as recited in one of the preceding claims, wherein the individual module (1) having the power balance table detects the connected individual modules (11, 21, 31, 41) independently and reads in the data necessary for preparing the power balance table.

16. The method as recited in one of the preceding claims, wherein the individual module (1) having the power balance table authorizes the release of the power supply and/or power consumption.

17. The method as recited in one of the preceding claims, wherein the release of the power supply and/or the power consumption is authorized successively with individual modules (1, 11, 21, 31, 41) being connected simultaneously.

18. The method as recited in one of the preceding claims, wherein, as a function of a load increase or a load decrease, an accumulator charge operation is switched over to an accumulator discharge operation, or vice versa.

19. The method as recited in one of the preceding claims, wherein the power supply via accumulators or batteries is switched off when the power supply takes place via a power supply unit (51).

20. A measuring system (100, 101) composed of a plurality of intermateable individual modules (1, 11, 21, 31, 41), part or all of these individual modules (1, 11, 21, 31, 41) being connectable via at least one power supply line (19, 29, 39, 49) and at least one data line (17, 27, 37, 47), at least one individual module (1, 31) of these individual modules having an interface (8, 18, 38) via which power is suppliable,

wherein a memory for preparing a power balance table based on power data from the connected individual modules and a control or regulating unit for controlling or regulating the power flow based on the data stored in the power balance table are provided in at least one individual module (1).

21. The measuring system as recited in claim 20, wherein each individual module (1, 11, 21, 31, 41) has at least one memory for component-related data;

and at least one individual module (1) has a memory for reading in the component-related data stored in the memories of the individual modules (1, 11, 21, 31, 41), and a control or regulating unit for controlling or regulating the power flow.

22. The measuring system as recited in claim 21,

wherein
