Description

Technical Field

[0001] This invention relates to the control of vehicle-mounted trash cans, and particularly to an intelligent control method and system for vehicle-mounted trash cans. Background Technology

[0002] During the transportation and dumping of garbage, it is usually necessary to obtain status parameters of the vehicle-mounted garbage bin, such as the bin's overflow level, temperature, power level, location, and movement trajectory. When abnormal conditions are detected, alarm signals also need to be sent to the driver or maintenance personnel. Especially for garbage bins carrying construction waste, they are typically equipped with overflow sensors, temperature sensors, power monitoring modules, GPS positioning modules, mobile network access modules, and alarm modules, each monitoring various status parameters of the garbage bin in real time. Because many modules in a vehicle-mounted garbage bin consume power, but their power supply is limited, they may need to operate continuously for extended periods during the day before being recharged. Therefore, insufficient power supply frequently occurs, causing some modules to passively enter a dormant state, unable to acquire and send signals regarding overflow level, temperature, power level, location, and movement trajectory when needed. This leads to problems such as the garbage bin being full and unable to be emptied in time, and the driver or maintenance personnel failing to notice abnormal temperatures inside the garbage bin, potentially leading to safety hazards.

[0003] Therefore, there is a need for an improved intelligent control method and system for vehicle-mounted trash cans. Summary of the Invention

[0004] To address the above problems, this invention proposes an intelligent control method for vehicle-mounted trash cans, comprising:

[0005] A triaxial sensor is used to detect whether the vibration level of the trash can reaches the set vibration threshold.

[0006] When the vibration level of the trash can reaches the set vibration threshold, the trash can enters the working mode. In the working mode, the fullness of the trash can is collected every first time period, the internal temperature of the trash can is collected every second time period, and the triaxial sensor continuously detects the vibration level of the trash can under the first power supply current.

[0007] When the vibration level of the trash can does not reach the set vibration threshold, the trash can enters a sleep mode. In the sleep mode, the overflow level and the internal temperature of the trash can are stopped, and the triaxial sensor continuously detects the vibration level of the trash can under the second power supply current, which is lower than the first power supply current.

[0008] This invention also proposes an intelligent control system for a vehicle-mounted trash can, comprising:

[0009] A triaxial sensor is configured to detect whether the vibration level of the trash can reaches a set vibration threshold.

[0010] An ultrasonic sensor array is configured to detect the overflow level of the trash can.

[0011] A temperature sensor is configured to collect the temperature inside the trash can; and

[0012] The controller is configured to:

[0013] When the triaxial sensor detects that the vibration level of the trash can reaches a set vibration threshold, the trash can enters the working mode. In the working mode, the controller controls the ultrasonic sensor group to collect the overflow level of the trash can every first time interval, controls the temperature sensor to collect the internal temperature of the trash can every second time interval, and controls the triaxial sensor to continuously detect the vibration level of the trash can under the first power supply current; and

[0014] When the triaxial sensor detects that the vibration level of the trash can has not reached the set vibration threshold, the trash can enters a sleep mode. In the sleep mode, the controller controls the ultrasonic sensor group to stop collecting the overflow level of the trash can, controls the temperature sensor to stop collecting the internal temperature of the trash can, and controls the triaxial sensor to continuously detect the vibration level of the trash can under the second power supply current, wherein the second power supply current is lower than the first power supply current.

[0015] The present invention also proposes a machine-readable storage medium storing executable instructions that, when executed by a processor, implement the intelligent control method for a vehicle-mounted trash can according to the present invention.

[0016] Using the method and system of this invention, the hardware modules of the vehicle-mounted trash can do not always need to be powered on, but can be powered on in time to collect various parameters of the trash can when needed, thereby realizing more energy-saving intelligent control for the trash can. Attached Figure Description

[0017] The invention will now be described in more detail with reference to the accompanying drawings, in which:

[0018] Figure 1 A schematic flowchart illustrating an intelligent control method for a vehicle-mounted trash can according to the present invention; and

[0019] Figure 2 A schematic block diagram of an intelligent control system for a vehicle-mounted trash can according to the present invention is shown. Detailed Implementation

[0020] The intelligent control method for a vehicle-mounted trash can according to the present invention generally includes the following steps:

[0021] A triaxial sensor is used to detect whether the vibration level of the trash can reaches the set vibration threshold.

[0022] When the vibration level of the trash can reaches the set vibration threshold, the trash can enters the working mode. In the working mode, the fullness of the trash can is collected every first time period, the temperature inside the trash can is collected every second time period, and the triaxial sensor continuously detects the vibration level of the trash can with the first power supply current.

[0023] When the vibration level of the trash can does not reach the set vibration threshold, the trash can enters a sleep mode. In the sleep mode, the overflow level and the internal temperature of the trash can are stopped, and the triaxial sensor continuously detects the vibration level of the trash can with a second power supply current, wherein the second power supply current is lower than the first power supply current.

[0024] In this system, a triaxial sensor is positioned inside the front of the garbage bin to sense the bin's acceleration and tilt angle in three axial directions, thereby detecting the bin's vibration level. The triaxial sensor can be, for example, located within the electrical control box at the front of the bin. Triaxial sensors are commonly used to detect forces and / or accelerations of objects. In this context, when a vehicle carrying a garbage bin dumps its waste, the entire front of the bin (the end closest to the driver's cab) is raised, and the door at the rear of the bin is opened to empty the waste contained inside. Therefore, the front of the garbage bin experiences significant vibration during dumping. In this situation, the vibration level of the garbage bin can be accurately detected by sensing the acceleration and tilt angle in three axial directions using a triaxial sensor positioned inside the front of the bin.

[0025] Typically, various condition parameters of the garbage bin need to be monitored during garbage dumping and loading, including overflow level and temperature. The garbage bin experiences significant vibration during these processes. Therefore, the bin can be put into operation when the vibration level reaches a set threshold to collect these parameters. However, even when not dumping or loading garbage, the garbage bin may still experience vibration, even significant vibration. For example, when a vehicle carrying the garbage bin travels over uneven roads, it will experience temporary vibration. During vehicle operation, it is unnecessary to continuously monitor the garbage bin's condition parameters, as such monitoring is very energy-intensive.

[0026] Therefore, this invention proposes that the trash can only enter the working mode when its vibration level reaches a set vibration threshold, and the overflow level of the trash can is collected every first time period, and the internal temperature of the trash can is collected every second time period. It should be noted that the "vibration threshold" referred to in this article does not refer only to the amplitude of the trash can's vibration, but to the duration for which the trash can maintains a set vibration amplitude, such as continuous vibration for 5 seconds, 10 seconds, etc.

[0027] For example, when dumping garbage, if the garbage can remains in a raised position for a long time, the triaxial sensor can detect that the garbage can vibrates to a certain amplitude and the vibration lasts for a certain period of time. In this case, the garbage can should be considered to enter working mode to detect various status parameters of the garbage can.

[0028] In contrast, when a vehicle carrying a garbage bin travels over an uneven road surface, it will experience temporary vibrations. Since the vibrations are short-lived, the method according to the present invention will determine that the vibration level of the garbage bin has not reached the set vibration threshold. Therefore, it is not necessary to switch the garbage bin to the working mode, thereby avoiding unnecessary continuous monitoring of various condition parameters of the garbage bin and reducing power consumption.

[0029] The vibration threshold can be set according to the driver's sensitivity requirements for vibration detection and the road conditions on which the vehicle carrying the garbage bin travels. If the driver wants the garbage bin to enter operating mode only when small vibrations and / or short durations are detected, a smaller vibration threshold can be set; conversely, if the driver wants the garbage bin to enter operating mode only when large vibrations and / or long durations are detected, a larger vibration threshold can be set. On the other hand, a smaller vibration threshold can be set when the road surface is relatively smooth, while a larger threshold can be set when the road surface is very uneven. For example, ten vibration thresholds from 1 to 10 can be set, with values ​​from small to large corresponding to increasing vibration amplitude and duration, and representing decreasing sensitivity to garbage bin vibration detection. Therefore, the vibration threshold setting in this invention is highly flexible, not only meeting the needs of different drivers but also minimizing power consumption caused by frequent switching of the garbage bin to operating mode.

[0030] In operating mode, the overflow level of the trash can is collected at the first time interval, and the internal temperature of the trash can is collected at the second time interval. For example, in operating mode, the overflow level of the trash can can be measured every 30 seconds. The overflow level can be determined by an ultrasonic sensor array consisting of multiple ultrasonic sensors distributed on the top wall inside the trash can. Each ultrasonic sensor can sense the distance to the trash located below it, but the trash in the trash can is usually not all at the same height, so using multiple ultrasonic sensors distributed in a dispersed manner can obtain the overflow level of the trash can more accurately.

[0031] Taking a distributed arrangement of six ultrasonic sensors as an example, each sensor can be positioned in the center and near the four corners of the top wall inside the trash can. Each sensor measures its own distance from the trash below. The maximum and minimum distance values, as well as outliers (such as a negative distance or a distance greater than the total height of the trash can's interior), can be removed. The average of the remaining measurements can be used to calculate the trash can's overflow level. The overflow level can be calculated as the height of the trash in the trash can divided by the total height of the trash can's interior.

[0032] Since the trash in a trash can may not always be stationary, the overflow level of the trash can measured at different times may vary. To obtain a more accurate overflow level, the overflow level of the trash can can be measured, for example, every 30 seconds, and this can be repeated for, for example, 10 times. The average of the 10 measurements can then be taken as the overflow level of the trash can.

[0033] In operating mode, the temperature inside the trash can can be sampled, for example, every 200ms. A temperature sensor can be used to sense the temperature inside the trash can. The temperature sensor can be positioned at the front interior of the trash can near the triaxial sensor, for example, it can also be positioned inside the electrical control box, but the invention is not limited thereto.

[0034] It should be noted that the triaxial sensor can detect the vibration level of the trash can regardless of whether it is in operating or sleep mode. However, the triaxial sensor is configured to detect the vibration level in two different modes. Specifically, in operating mode, the triaxial sensor is supplied with a higher initial supply current, allowing it to detect the vibration level with higher sensitivity; this can also be referred to as the normal mode of the triaxial sensor. In sleep mode, the triaxial sensor is supplied with a relatively lower second supply current. It can still detect the vibration level, but the sensitivity is relatively reduced; therefore, this can also be referred to as the standby mode of the triaxial sensor. Thus, in sleep mode, the power consumption of the triaxial sensor is reduced, but it can still detect the vibration level of the trash can. Once the vibration level is determined to reach a set vibration threshold, the trash can switches from sleep mode to operating mode for more sensitive vibration detection. Regardless of whether the trash can is in operating or sleep mode, the triaxial sensor can be configured to collect the vibration level of the trash can every 500ms.

[0035] In addition to collecting data on the vibration level, overflow level, and temperature of the trash can, the method according to the present invention may also include collecting data on the movement trajectory and positioning of the trash can, monitoring the power supply to each module of the trash can, and sending alarm signals to the driver or maintenance personnel when necessary.

[0036] Vehicles carrying garbage bins can be equipped with positioning modules (such as GPS) to collect the bin's movement trajectory and location, power monitoring modules to monitor the power supply to the bin's components, alarm modules to send alert signals to the driver or maintenance personnel (e.g., when abnormal parameters related to bin overflow, temperature, movement trajectory and location, or power supply are detected), and mobile network access modules to transmit the acquired bin status parameters to the driver or cloud. These modules can be located at the front interior of the garbage bin, such as within the electrical control box, and can be integrated with triaxial and temperature sensors to simplify wiring and facilitate maintenance. Furthermore, during operation, the collection of the garbage bin's movement trajectory and location, as well as power supply data, can be performed at predetermined intervals.

[0037] In the working mode of the trash can, various status parameters of the trash can can be detected and collected normally, including the vibration level of the trash can, the overflow level of the trash can, the internal temperature of the trash can, the movement trajectory and positioning of the trash can, the power supply to the various components of the trash can, and alarm signals. In other words, in the working mode of the trash can, the triaxial sensor, ultrasonic sensor group, temperature sensor, positioning module, power monitoring module, and alarm module are each supplied with current normally.

[0038] In the trash can's sleep mode, only the triaxial sensor is supplied with current, and the current supplied is lower than in operating mode, while other sensors and modules are deprived of current. Therefore, sleep mode can significantly reduce the power consumption of the trash can's sensors and modules.

[0039] According to the method of the present invention, the trash can needs to meet the following conditions to switch from working mode to sleep mode:

[0040] In the working mode, the triaxial sensor detects that the trash can changes from vibration to stillness (the vibration level of the trash can changes from reaching the set vibration threshold to not reaching the set vibration threshold) and remains still for a set duration (e.g., 30 seconds).

[0041] In other words, the advantage is that the trash can does not switch directly from working mode to sleep mode every time it is detected that the trash can has changed from vibration to stillness. Instead, it needs to be detected that the stillness has lasted for a certain period of time before switching from working mode to sleep mode. This can avoid the trash can switching frequently between working mode and sleep mode.

[0042] According to the method of the present invention, the trash can needs to meet the following conditions to switch from dormant mode to working mode:

[0043] (1) In sleep mode, if the triaxial sensor detects that the trash can has changed from being stationary to vibrating (the vibration level of the trash can changes from not reaching the set vibration threshold to reaching the set vibration threshold), then the trash can directly switches from sleep mode to working mode; or

[0044] (2) If the trash can remains in sleep mode for a set period of time, the trash can will switch from sleep mode to working mode.

[0045] The second scenario indicates that even if no change from a stationary to a vibrating state is detected in the sleep mode, the trash can will switch to operating mode after a period of time. This ensures that various status parameters of the trash can are collected at least once every certain period of time, preventing a complete loss of information about the trash can's status during sleep mode. For example, even if the trash can remains stationary for an extended period in sleep mode, its overflow level, temperature, location, and trajectory can still be collected periodically.

[0046] To address this, a countdown timer for the sleep cycle can be set each time the trash can switches from working mode to sleep mode, such as 24 minutes. Once the countdown ends, the trash can will switch back from sleep mode to working mode.

[0047] As described above, in the operating mode, various parameters of the trash can are collected at corresponding time intervals. However, not every time these parameters are collected, they need to be reported, for example, to the driver or the cloud. Instead, the method according to the present invention only reports the parameters in the following situations:

[0048] (1) In working mode, report each parameter according to the set reporting cycle;

[0049] (2) When the triaxial sensor detects that the trash can changes from being stationary to vibrating (the vibration level of the trash can changes from not reaching the set vibration threshold to reaching the set vibration threshold), it reports each parameter.

[0050] (3) In the working mode, when the ultrasonic sensor group detects that the overflow of the trash can reaches the set value (e.g., 20%, 40%, 60% and 80%), it reports each parameter.

[0051] The first scenario indicates that, under normal circumstances in the working mode, the various parameters collected will be reported once every set reporting period (e.g., 24 minutes).

[0052] The second scenario indicates that a report is made every time the trash can is detected to change from being stationary to vibrating, thus allowing for the timely acquisition of various status parameters of the trash can when it changes to vibrating.

[0053] The third scenario indicates that a report is sent whenever the garbage bin's overflow level reaches certain specific values, allowing drivers to stay informed about changes in the bin's overflow level. It should be noted that the overflow level threshold triggering the report can be flexibly adjusted based on actual needs.

[0054] It should be noted that the reporting time for the first scenario can be affected by the second scenario, but not by the third scenario. Taking a 24-minute reporting cycle as an example, under normal circumstances in working mode, a new report will be made 24 minutes after the first report. However, if a report for the second scenario is made after a change from a stationary to a vibrating trash can during the interval between two first-scenario reports (e.g., 5 minutes after the last first-scenario report), the next first-scenario report will be made 24 minutes after the second scenario report (29 minutes after the last first-scenario report). However, if a report for the third scenario is made after the trash can's overflow rate reaches 20%, 40%, 60%, and 80% during the interval between two first-scenario reports (e.g., 5 minutes after the last first-scenario report), the next first-scenario report can still be made 24 minutes after the last first-scenario report, regardless of any third-scenario reports occurring during that period. This ensures that the number of reports is not excessive, but rather kept at a reasonable level.

[0055] The following is a brief summary of the intelligent control method for the vehicle-mounted trash can according to the present invention. (Refer to...) Figure 1 It shows a schematic flowchart of a method according to the present invention, the method comprising:

[0056] S101: With the system powered on, detect whether the vibration level of the trash can reaches the set vibration threshold. If it does, proceed to step S201; otherwise, proceed to step S301.

[0057] In step S201, the trash can enters the working mode and further performs the following steps:

[0058] S202: To supply current to all components of the system so that various status parameters of the trash can are collected at regular intervals, including the trash can's fullness, temperature, movement trajectory and positioning, and power supply. When abnormality of the above parameters is detected, an alarm signal is issued.

[0059] S203: Determine whether to report parameters such as the overflow level, temperature, movement trajectory and location of the trash can, and power consumption. The situations requiring reporting have been explained in detail above, so they will not be repeated here.

[0060] S204: Determine whether the trash can needs to switch from working mode to sleep mode. The specific determination method has been explained in detail above, so it will not be repeated here.

[0061] On the other hand, in step S301, the trash can enters a sleep mode and further performs the following steps:

[0062] S302: Continuously monitors the vibration level of the trash can under low supply current and stops collecting parameters related to the trash can's overflow level, temperature, movement trajectory and positioning, and power consumption;

[0063] S303: Determine whether the trash can needs to switch from sleep mode to working mode. The specific determination method has been explained in detail above, so it will not be repeated here.

[0064] The method according to the invention may also include manually setting a sleep period by the driver or others. For example, vehicles carrying garbage bins typically only load, unload, and haul garbage during the day; therefore, the garbage bins can be manually set to remain in sleep mode at night or during non-working hours to minimize power consumption. Additionally, during night or non-working hours, the system can be set to not report various parameters collected from the garbage bins, but to report the latest parameters only when the vehicle is started.

[0065] The present invention also proposes an intelligent control system for vehicle-mounted trash cans. Figure 2 A schematic block diagram of an intelligent control system 100 for a vehicle-mounted trash can according to the present invention is shown. The system 100 includes:

[0070] The controller 140 is also configured to cause the trash can to enter a sleep mode when the triaxial sensor 110 detects that the vibration level of the trash can has not reached a set vibration threshold. In the sleep mode, the controller 140 controls the ultrasonic sensor group 120 to stop collecting the overflow level of the trash can, controls the temperature sensor 130 to stop collecting the internal temperature of the trash can, and controls the triaxial sensor 110 to continuously detect the vibration level of the trash can with a second power supply current, wherein the second power supply current is lower than the first power supply current.

[0071] System 100 may also include a positioning module 150, a power monitoring module 160, and an alarm module 170. The functions of these modules have been described previously and will not be repeated here. The controller 140 is configured to supply current to the positioning module 150, power monitoring module 160, and alarm module 170 in operating mode, and is configured to deprive them of current in sleep mode.

[0072] System 100 may also include a timer 180, which is set with the aforementioned reporting period and sleep period. For ease of operation of timer 180, both the reporting period and sleep period can be set to 24 minutes as discussed above.
