Definitions
- the invention relates to a method for operating an event counter.
- the invention further relates to an apparatus for counting events.
- pedometer which is used to extract step events from an acceleration signal.
- a pedometer is known, for example, from EP 1 770 368 A1.
- the extraction of the step events is based on a detection of a peak or a signal peak value.
- the known systems usually use a sensor modality, for example in the form of an acceleration signal. This may be associated with a partially erroneous detection of events when the event counter is subjected to or undergoes vibrational driving with intense changes of direction (e.g., maneuvers in serpentines).
- the object is achieved with a method for operating an event counter, comprising the steps:
- the second sensor is thus only switched on temporarily, whereby it is determined with high reliability whether a counting event is present or not.
- An advantageous development of the method provides that the signal of the second sensor is used periodically over a useful life of the event counter. In this way, advantageously a very high detection accuracy can be achieved.
- a further advantageous development of the method provides that the signal of the second sensor is switched on in the presence of a defined property of the signal of the first sensor. In this way, a kind of plausibility check can be performed that implements an adaptive connection, whereby the count event is verified. It is therefore always switched on only if it is assumed that a counting event has probably taken place.
- the defined property of the signal of the first sensor is one of: arithmetic mean, standard deviation, ratio of large to small value within a temporal segment. In this way, appropriate signal sizes are used to perform a plausibility check of the count event.
- a further advantageous development of the method provides that a temporal minimum distance is maintained between the connections of the signal of the second sensor. In this way, it is advantageous to eliminate scenarios in which there are situations that do not represent true counter events.
- a further advantageous development of the method provides that the signal of the second sensor is only switched on periodically when the signal of the first sensor has a defined property. This allows for maximum detection quality and energy savings, because the second sensor is only switched on periodically, if with a high probability
- a further advantageous development of the method provides that associated different operating modes of the event counter are adjustable. This can be done, for example, by a user of the event counter.
- a further advantageous development of the method provides that the first sensor is an acceleration sensor and the second sensor is a rotation rate sensor. In this way signals from sensors are used, which are very well suited for the differentiation of counting events.
- the event counter is a pedometer.
- the plausibility of step events is particularly useful because the pedometer is commonly used often in non-unique situations that do not represent count events.
- 1 shows a first embodiment of a sequence of a method according to the invention
- 2 shows a further variant of a sequence of the method according to the invention
- Fig. 3 shows a further variant of a sequence of the invention
- Fig. 4 shows an embodiment of an inventive
- a use of a rotation rate sensor is proposed, which is only temporarily and in particular only switched on when a probability of a counting event is given.
- a "driving" scenario can be recognized from a combination of the sensor signals of the acceleration and yaw rate sensors by determining or extracting properties of the sensor signal of the acceleration sensor, for example a mathematical mean value, a standard deviation, a relation of large ones to be small values within a temporal section, etc.
- the rotation rate sensor In order to keep electrical energy consumption of the overall system low, the rotation rate sensor as a main electrical consumer is as rare as possible switched on. This can be done in several ways described below.
- FIG. 1 it is shown in principle that the rotation rate sensor is switched on periodically in a fixed time grid and the criterion for counting steps is checked ("periodic variant").
- a value of an acceleration is determined.
- a count event e.g. detects a step which is buffered in a step 202.
- a signal of a rotation rate sensor is switched on periodically.
- the method described thus switches on the signal of the yaw rate sensor regularly, which admittedly results in a certain increase in electrical energy consumption for the event counter, whereby, however, a very accurate operating behavior of the event counter can be achieved with it.
- Steps 300 to 302 correspond to steps 200 to 202 of Fig. 1.
- a step 303 a criterion corresponding to a probable count event is applied, and then a decision is made in step 304 whether the event count is valid (step 305) or discarded (step 306).
- a further modification of the method is shown in principle in FIG. Steps 400 to 402 correspond to steps 200 to 202 of FIG. 1 and steps 300 to 302 of FIG. 2, respectively.
- step 403 the criterion of the signal of the rotation rate sensor is periodically applied, wherein in a step 404 it is decided whether the counting event is valid (step 405) or discarded (step 406).
- the method represents an adaptive periodic variant in which the signal of the rotation rate sensor is switched on periodically at times in which a connection criterion is met to further reduce the power consumption.
- a connection criterion is met to further reduce the power consumption.
- a selection of the different three operating modes of the event counter described in FIGS. 1 to 3 can be set either by a user, for example via a selection relating to an associated electrical energy consumption. Also possible is a fixed assignment of the operating mode to a design of the event counter, e.g. in the form of a tablet, a smartphone, a sports bracelet, a fitness tracker, etc.
- Fig. 4 shows a simplified schematic representation of an event counter 100. It can be seen that the event counter 100 has a first sensor 10 in the form of an acceleration sensor and a second sensor 20 in the form of a rotation rate sensor. Signals of said sensors 10, 20 are interchanged or fed to a computer means 30 (e.g., a microcontroller or an ASIC), the gyroscope sensor signal for counting events being switched on only temporarily and depending on certain criteria.
- a computer means 30 e.g., a microcontroller or an ASIC
- the method according to the invention can be implemented as an algorithm of a software program for the computer device 30, where appropriate, depending on the form factors, certain limitations
- the present invention proposes an improved method for operating an event counter, with which it is advantageously possible to advantageously increase a detection accuracy of counting events, wherein an associated additional electrical energy consumption is minimized.
- the pedometer is supplemented by various plausibility queries. If the information obtained from the acceleration sensor is insufficient to perform a complete plausibility check, at least one additional sensor, such as the rotation rate sensor, is activated. Of course, it is also possible to use signals from several sensors for the plausibility checks.
- the detection accuracy can advantageously be optimized with the lowest possible additional electrical consumption.
- the method according to the invention makes it possible to suppress or at least minimize "false positive detection" of step events, wherein steps are only counted or detected if they actually exist, and if no steps are present, they also become not counted or detected In this way, optimum parameterization of the step counter is supported.
