the height h is in the range of [0.5m,1.2m ]]From this, it can be derived that the time range is [316ms,489ms ]]Considering the detection delay and the reception delay, the preset time range under the free fall model can be determined as 300ms,500ms](ii) a To obtain the minimum motion time, the detection delay and the reception delay may be considered first, and the average is about 20ms, and the preset time minimum may be set to 25ms, so that, in some embodiments, the preset time range may be [25ms,500ms ]]。

In some embodiments, the determining whether the acceleration reaches the first threshold when receiving the acceleration detected by the acceleration detection module in real time in the wake-up period may specifically include:

receiving a first acceleration detected by an acceleration detection module, and judging whether the first acceleration reaches a first threshold value;

if the first acceleration reaches a first threshold value, whether a second acceleration detected by the acceleration detection module is received or not is detected within a preset time range;

and if the second acceleration detected by the acceleration detection module is received, judging whether the second acceleration reaches a first threshold value.

In specific implementation, the acceleration detection module in the dormant state is awakened at regular time, the awakened acceleration detection module detects the acceleration of the garbage can in real time, when the first acceleration sent by the acceleration detection module is received, whether the first acceleration reaches a first threshold value is judged firstly, whether the generated first acceleration is the acceleration generated due to the action of external force is judged, if the first acceleration is determined to be generated under the action of external force, the first acceleration is stored, whether the second acceleration sent by the acceleration detection module is received continuously within a preset time range, and if the second acceleration is received within the preset time range, whether the second acceleration reaches the first threshold value is judged continuously, so that whether the garbage can topples or not is known, and therefore, the low-power-consumption real-time detection is realized, and meanwhile, the phenomenon that the garbage can shakes due to environmental factors is effectively avoided, The interference of the conditions such as state change and the like during the cleaning of the garbage can on the detection of the dumping state.

In order to further save power consumption, in some embodiments, after receiving the first acceleration detected by the acceleration detection module and determining whether the first acceleration reaches the first threshold, the method for detecting the dumping status of the trash can may further include:

If the first acceleration does not reach the first threshold, the first acceleration generated under the current condition is not in accordance with the condition of toppling under the action of external force, the acceleration detection module can be triggered to enter the dormant state without storing the first acceleration or continuously detecting whether the second acceleration is received within the preset time range, so that the real-time detection under the low-power consumption state is realized, invalid data is also cleared in real time, and the memory is saved.

Correspondingly, after detecting whether the second acceleration detected by the acceleration detection module is received within the preset time range, the method for detecting the dumping state of the trash can further includes:

In specific implementation, if the second acceleration detected by the acceleration detection module is not received within the preset time range, it is indicated that the garbage can is possibly influenced by other factors and does not finish dumping under the action of external force, that is, the dumping of the current garbage can is not established, the storage of the first acceleration is cleared, and the acceleration detection module is triggered to continue to enter the sleep mode.

Similarly, after determining whether the second acceleration reaches the first threshold, the method for detecting the dumping status of the trash can may further include:

and if the second acceleration does not reach the first threshold value, clearing the storage of the first acceleration, and triggering the acceleration detection module to enter a dormant state until the acceleration is detected again in real time in the next awakening period.

In some embodiments, the method for detecting the dumping state of the trash can further includes:

and if the inclination angle does not reach the second threshold value, determining that the garbage can is not in the dumping state currently.

During specific implementation, even if the garbage can is dumped, if the inclination angle does not reach the second threshold value, the situation that the dumping of the garbage can is very small can be determined, the normal work of the garbage can is not influenced, at the moment, the garbage can is not in the dumping state currently, and meanwhile, the storage of the first acceleration and the second acceleration is eliminated. Therefore, the accuracy and effectiveness of the detection result are ensured, the interference brought by error information to sanitation workers is avoided, and the memory space is saved. For example, a trash can leaning against a wall may tilt such that the trash can rests against the wall, but the trash can still be used properly, and such dumping may occur without the need for a sanitation worker to go ahead.
