Abstract

The invention relates to a method for the acquisition and storage of measured values, according to which measured values (MW1i, MW2i, MW3i) are continuously acquired by at least one sensor in a predefined first measurement interval (T1). The acquired measured values (MW1i, MW2i, MW3i) are stored in a measured value memory (K1, K2, K3). The invention is further characterized in that upon occurrence (EA) of an event detected by an event sensor one or more further measured value(s) (MW14, MW15, MW16, MW17, MW18, MW19, MW110, MW24, MW25, MW26, MW27, MW28, MW29, MW210, MW34, MW35, MW36, MW37, MW38, MW39, MW310) are acquired by the at least one sensor and/or one or more further measured values are acquired with a further measurement interval (T2) in an asynchronous manner to the first measurement interval (T1) and are stored in the measured value memory (K1, K2, K3).

Claims

1. A method of measured value acquisition and storage in which measured values (MW11, MW2i, MW3i) are continuously gathered by at least one measured value sensor in a fixedly predetermined first measuring cycle (T1), and the measured values (MW1i, MW2i, MW3i) gathered are stored in a measured value memory (K1, K2, K3), wherein, due to the occurrence of an event, detected by an event sensor, one or several other measured value(s) (MW14, MW15, MW16, MW17, MW18, MW19, MW110, MW24, MW25, MW26, MW27, MW28, MW29, MW210, MW34, MW35, MW36, MW37, MW38, MW39, MW310) are gathered by the at least one measured value sensor and/or by at least one additional measured value sensor asynchronously with the first measuring cycle (T1) or any other measuring cycle (T2) and are stored in the measured value memory (K1, K2, K3).

2. The method as recited in claim 1, wherein the additional measured values (MW14, MW15, MW16, MW17, MW18, MW19, MW110, MW24, MW25, MW26, MW27, MW28, MW29, MW210, MW34, MW35, MW36, MW37, MW38, MW39, MW310) are gathered in a fixedly predetermined second measuring cycle (T2).

3. The method as recited in claim 1 or claim 2, wherein the additional measured values (MW14, MW15, MW16, MW17, MW18, MW19, MW110, MW24, MW25, MW26, MW27, MW28, MW29, MW210, MW34, MW35, MW36, MW37, MW38, MW39, MW310) are gathered as long as the event (EA, EE) continues to exist.

4. The method as recited in one of the preceding claims, wherein, due to the non-occurrence (EE) of the event, detected by the event sensor, one or several additional measured value(s) (MW111, MW112, MW113, MW114, MW211, MW212, MW213, MW214, MW311, MW312, MW313, MW314) are gathered by the at least one measured value sensor and/or the at least one other measured value sensor asynchronously with the first measuring cycle (T1) and/or asynchronously with the second measuring cycle (T2) and are stored in the measured value memory (K1, K2, K3).

5. The method as recited in claim 4, wherein the additional measured values (MW111, MW112, MW113, MW114, MW211, MW212, MW213, MW214, MW311, MW312, MW313, MW314) are gathered in the fixedly predetermined first measuring cycle (T1).

6. The method as recited in one of the preceding claims, wherein at the start (t1) of the measured value acquisition (M1), the point in time of the measured value acquisition start is stored in the measured value memory (K4).

7. The method as recited in one of the preceding claims, wherein the time difference (Δ

ti), between measured value acquisition time (t1) of the instantaneous measured values and measured value acquisition time (ti-1) of the previous measured values (MW1i-1, MW2i-1, MW3i-1), associated with each stored measured value (MW1i, MW2i, MW3i where i=2 . . .

     14)), is stored in the measured value memory (K4).

8. The method as recited in claim 7, wherein the time difference (Δ

ti) is stored as a 15-bit data word (B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B13, B14, B15).

9. The method as recited in one of the preceding claims, wherein the state (Si) of the event is stored for each stored measured value (MW1i, MW2i, MW3i) in the measured value memory (K4).

10. The method as recited in claim 9, wherein the state (Si) of the event is stored as a 1-bit data word (B16).

11. The method as recited in one of the preceding claims, wherein the measured values (MW1i, MW2i, MW3i) are stored as 15 bit data words (B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B13, B14, B15) plus one sign bit (B16, Vz1i, Vz2i, Vz3i) each.

12. The method as recited in one of the preceding claims, wherein at least one temperature sensor, at least one air moisture sensor, at least one flow sensor, and/or the like is used as the measured value sensor.

13. The method as recited in one of the preceding claims, wherein at least one door contact and/or one measured value sensor is used as the event sensor.

14. The method as recited in one of the preceding claims, wherein the event is the closing of a door contact, the excess or dropping below a threshold value, the excess or dropping below a change of a measuring signal, or the like.
