Description

DESCRIPTION

Garbage container with a sensor system

The invention relates to a garbage container comprising at least one closing mechanism for closing at least one opening and an electronic device having an electronic control device, at least one locking device for at least one closing mechanism, a system sensor comprising at least one motion sensor and transmitting detected sensor signals to the electronic control device, and a transmitting device for transmitting sensor signals from the sensor system to the electronic control device and / or transmitting control signals from the blocking device from the electronic control device to the blocking device, the transmission of signals being carried out wirelessly or by means of a physical connection according to the preamble of claim 1. Furthermore, the invention deals with a method for emptying said garbage container according to claim 12.

For household waste disposal in townhouses, apartment buildings, apartment blocks, or communities, large-scale garbage containers that have a lockable opening are commonly used to dispose of the garbage and empty the garbage container. The locking device can be unlocked by the disposal company or residents with proper identification, so that it is possible to empty the garbage container or throw the garbage in the garbage container. A garbage container locked in this way prevents unauthorized persons from opening the garbage container. For example, access blocked for people who have not paid their waste disposal fees.

When emptying a garbage container by the disposal company with a garbage truck, there are generally two steps: first, in a first step, the garbage container is lifted by the garbage truck and then it is tilted in a second step. and the garbage truck pushes the opening to open it in order to empty the garbage from the garbage container into the garbage truck. Unlocking the opening must be done in the first step, that is, during lifting. Unlocking the opening (lid) during tilting is no longer possible due to the frictional forces of the lid hook on the latch, and in this case the waste container cannot be emptied.

Therefore, garbage containers have a lift detection system. For this, a motion sensor is used that unlocks the locking device in the event of an impact. Thus, it is possible in this way, for example, to cause unlocking by improper movement of the garbage container.

Document US 2014/0208813 A1 shows such a garbage container according to the preamble of claim 1. The garbage container has a closed locking mechanism that can be actuated by means of an actuator. A control module controls the actuator based on data from a motion sensor.

In addition, the garbage containers have an emptying detection system to, on the one hand, release the locking device again after emptying, so that users can throw the garbage into the now empty garbage container. In addition, the information about the emptying can be sent to a waste management system, so that specific emptying or redirection of users to empty containers is made possible through an information system.

Until now, the detection of the emptying of the garbage container is done through a communication device that connects to the on-board computer (OBC) of the garbage truck. This means that whenever communication with a garbage truck is possible, the emptying of the garbage container is automatically recognized.

Document WO 2016/187677 A1 shows an acknowledgment of emptying a garbage container. A corresponding processor is configured to recognize a flush process and forward or store the corresponding information. The processor evaluates information that can come from a sensor and / or that can be time stamps. Possible sensors that can be used can include motion sensors, fill level sensors, pressure sensors, or temperature sensors.

In other garbage containers that do not have a communication system, an emptying is recognized as a result of the recognized lift. This may mean that if the lift is not detected, no dump is detected even though the lift has occurred. Also, if a lift is falsely recognized, a void may be falsely recognized, even though this has not occurred at all.

The object of the present invention is to separate the detection of lifting and emptying of the garbage container so that the detection of emptying occurs independently of the detection of lifting, and further improve detection of the lift so that it takes place in time before the dumpster is overturned and a remote station on the dump truck (OBC) is no longer required.

This object is achieved by means of a garbage container comprising at least one closing mechanism for closing at least one opening and an electronic device that includes an electronic control device, at least one locking device for at least one closing mechanism, in a sensor system comprising at least one motion sensor and transmitting detected sensor signals to the electronic control device and a transmitting device for transmitting sensor signals from the sensor system to the electronic control device and / or device control signals lock from the electronic control device to the lock device, wherein the transmission of signals is done wirelessly or through a physical connection. The invention is characterized in that the sensor system has at least two sensors, namely the motion sensor and a level sensor, by means of which the lifting of the garbage container can be detected, whereby the electronic control device from from the sensor signals of both sensors you can generate a lock device control signal to open at least one lock device.

With a garbage container equipped in this way, the uplift detection is performed by combining the sensor information from the motion sensor with the sensor information corresponding to the level sensor. For this, if the garbage container vibrates, the motion sensor detects it, the level sensor being activated through the electronic control device. This measures the lifting process during which the dumpster is raised, usually at least one meter. The lifting process is then recognized in the electronic control device, after which the lock device control signal is generated to open the lock device. By using the sensor system according to the invention, the opening is unlocked in time and then during the tipping process it can be opened by pushing action of the garbage truck.

The garbage container is preferably powered by a suitable battery, for example equipped with a solar cell to generate power, or by a battery that is regularly replaced by the waste management company. The power supply of the garbage container can also be stationary, for example via a live wire.

According to at least one further manufacturing example, the electronic control device comprises a signal generation unit that generates the control signals of the locking device and / or the control signals of the sensor. In the case of the signal generation unit, it can be a digital-to-analog converter or, in general, a unit that generates a suitable control signal, for example a control voltage, for transmission to the control system. sensors or locking device. The control signal can also be logic information directly.

According to at least one other manufacturing model, the level sensor is controlled by the electronic control device that can be activated by the control signals from the sensor. This can be done, for example, by direct interconnection or by transmitting alert information. It would also be possible for the level sensor to deliver signals from the sensor all the time, but for these to be transmitted to the electronic control device only directly after the movement of the dumpster has been detected, or for these to only be subsequently evaluated in the electronic control device.

Advantageously, the transmission device is also suitable for transmitting sensor control signals from the electronic control device to the sensor system and / or status signals of the locking device from the locking device to the electronic control device. The signals are transmitted wirelessly or through a physical connection.

Wireless transmission of sensor signals, sensor control signals, locking device control signals and locking device status signals can take place via a suitable ISM connection, for example W-LAN, radio, Bluetooth, RFID, n Fc or similar, but also through a mobile phone connection or other suitable wireless technologies. For the implementation of the transmission device as a physical connection, cables, interconnections or any other conductor can be used, or suitable connections can be used for the transfer of information. Furthermore, it is conceivable that the transmission unit is designed as a purely logical unit.

According to at least one other manufacturing model, the electronic control device comprises a storage unit in which the data of the detected sensor signals and / or data on recognized lifting processes and / or data on recognized emptying processes can be stored. . Furthermore, it is conceivable that the storage unit stores data on the status of the locking device, generated from the status signals of the locking device. This storage unit is preferably realized as a non-volatile memory so that a constant power supply of the storage unit is not necessary. storage to receive the stored data. This reduces the total energy consumption of the dumpster, which on the one hand reduces the requirements for a battery-based dumpster power supply and on the other hand saves energy resources. For example, the storage unit can be FLASH memory (SSD memory), phase change memory, resistive RAM (RRAM), or any other non-volatile memory technology known to one of ordinary skill in the art.

The storage drive can also be realized as a classic hard drive or by any other suitable storage technology.

According to at least one other manufacturing model, the electronic control device comprises a comparison unit in which the data of the detected sensor signals can be compared with the data of previous sensor signals stored at a previous time.

In the comparison unit, when comparing the stored and current data, for example, it is recognized whether, after the vibration of the garbage container detected by the motion sensor, the appropriate data is present from the sensor signals that correspond to the level sensor, indicating a lift, so that the lifting of the container can be safely recognized. Furthermore, it is conceivable that the comparison unit compares the sensor signals with patterns stored in the storage unit, so that lifting or emptying is only recognized in the case of sensor signals meeting certain criteria. Furthermore, when comparing the stored data and the current data, the comparison unit recognizes, for example, if when detecting an inclination of the garbage container, a lifting and therefore an emptying took place directly before this event.

The comparison unit is preferably manufactured as a processor or as any other type of data processing logic. Furthermore, the comparison unit has a main memory in which the comparison unit temporarily stores data from the storage unit for comparison.

Furthermore, it is conceivable that the electronic control device also comprises a signal input unit, in which the incoming signals are received from the transmission unit. This signal input unit may be a receiver unit suitable for receiving wirelessly transmitted signals. If the signals are transmitted through a physical transmission medium, the signal input unit can be used as a female connector to couple a signal from the transmission unit or as a connection between conductive tracks and chips with integrated circuits, for example example, as a link cable or crimp connection in an arrangement on a printed circuit board. Furthermore, the electronic control device may comprise a signal output unit. This signal output unit may be a transmission unit suitable for transmitting wirelessly transmitted signals. If the signals are transmitted through a physical transmission medium, the signal output unit (37) can be used as a female connector to decouple a signal from the transmission unit, or as a connection between chips with integrated circuits and conductive tracks, for example as a bonding wire or a crimp connection in an arrangement on a printed circuit board.

Furthermore, both the sensor system and the locking device may each comprise a signal input unit and / or a signal output unit, according to the above description.

Furthermore, the electronic control device may comprise a signal verification unit which verifies the plausibility of the incoming signals, for example the correct signal or the inclusion of a verification number or other identification. It is also conceivable that the signal test unit applies filtering techniques to the signal. The signal verification unit thus significantly increases the security of the electronic device of the dumpster and reduces possible false identifications of lifting or emptying.

Furthermore, the electronic control device may comprise an evaluation unit that evaluates the incoming signals. The signals are examined for their information content. The evaluation unit then transmits the signals and / or the evaluated information to the comparison unit.

In addition to a signal input unit and a signal output unit, the locking device preferably further comprises a comparison unit, a storage unit and a control unit. The control unit directly controls the unlocking mechanism of the locking unit. Data about the status ("unlocked" or "locked") of the locking device is stored on the storage drive. The comparison unit compares the incoming locking device control signals with the locking device states stored in the storage unit. In this way, for example, in the unlocked state, a new activation of the locking mechanism for unlocking can be prevented, and thus a mechanical overload of the locking mechanism can be avoided. A similar procedure is conceivable in the locked state for a new activation of the locking mechanism for locking

According to at least one other manufacturing model, the level sensor is an air pressure sensor.

In addition, the level sensor can also be configured as a ground clearance laser measurement unit, a photo-detector that is illuminated with ambient light by lifting the garbage container, an ultrasonic sensor, an optical camera or any other sensor system. known to a person skilled in the art, that it is suitable for measuring and detecting the lifting of the dumpster.

According to at least one additional production model, all sensors of the sensor system each have at least one calibration unit for level calibration and / or position calibration.

Due to the change in air pressure due to height, the lifting of the dumpster can be recognized. In addition to the change in height, the air pressure is also subject to change due to the weather. Therefore, for the correct measurement of the height during the lifting of the garbage container with the air pressure sensor, it is especially necessary to measure the current air pressure on the ground in order to compare this measured value with the air pressure measured at lift height. To do this, the air pressure sensor calibration unit measures, for example, at regular time intervals or at the moment when the acceleration sensor provides the first indications of a possible increase, the air pressure and provides this value. measured as a comparison value for height measurement. The time intervals are short enough that even in the case of sudden climatic changes which however, by comparison, run slowly for a dumpster lifting process, a current air pressure is available at any time from the ground for height measurement.

For correct measurement of a minimum angle of rotation when tilting the garbage container during emptying to detect it, it is also necessary to calibrate the angle of rotation absolutely, so that it can be distinguished, for example between a rotation of -90 ° to 90 °, for example by rocking the garbage container by unauthorized persons, and a rotation from 0 ° to 180 ° when emptying the garbage container. For this purpose, the motion sensor also features a calibration unit which, at sufficiently short time intervals or when uplift is detected, analogously to the calibration unit of the air pressure sensor, measures the position angle of the air pressure sensor. garbage container, where this value defines the 0 ° point.

According to at least one other manufacturing model, the garbage container comprises a separate opening for throwing the garbage into the garbage container and / or a separate emptying opening for emptying the garbage from the garbage container, each of which has at least one lock and a locking device, it being possible with the help of the electronic control device to generate locking device control signals to open the locking devices.

According to at least one additional manufacturing model, at least one locking device is a gravity lock.

In this case, the locking device formed as a gravity lock is not controlled from the electronic control device, but is operated only by gravity or some other mechanical mechanism.

In the event that the device for blocking the opening used for emptying is a gravity lock, the sensor system according to the invention recognizes lifting and / or emptying.

According to at least one other manufacturing model, the garbage container includes in addition to the opening, through which the garbage container is emptied, a separate closing mechanism for closing a separate opening with the help of a separate locking device, the initial opening locking device being a gravity lock and with the help of the electronic control device a control signal of the locking device can be generated to open the independent locking device.

The task is also solved by a method of emptying a garbage container according to one of claims 1 to 11, comprising the following steps:

- Raise the garbage container and detect a movement of the garbage container by means of the movement sensor of the sensor system;

- Activation of the level sensor by means of the electronic control device by transmitting a control signal from the sensor after motion detection;

- Detection of the lifting of the garbage container by means of the sensor signals of the activated level sensor;

- Generation of a locking device control signal to open the locking device by means of the control device;

- Empty the container and detect the emptying of the container by comparing the data of the sensor signals of the motion sensor with the data of the detection produced from the lifting in a comparison unit. The level sensor is preferably activated only after the garbage container has detected movement by the motion sensor. In this way it is ensured that lifting detection only takes place by means of the characteristic sequence "vibration of the garbage container" - "Modification of the height at which the garbage container is located".

Reliable lifting detection opens the locking device in time, so that a locking of the locking device is prevented by the friction forces of the lid hook on the latch and can be opened by pushing action of the collection vehicle of garbage.

According to at least one further manufacturing model, the motion sensor when emptying the garbage container detects a tilting movement at a minimum angle of rotation and then generates a sensor signal. This sensor signal is then transmitted through the transmission unit to the electronic control device. There, in the comparison unit, this signal is compared with the data of the previous sensor signals. Only if a characteristic sequence was detected there, for example: "Lifting detection" - "Exceeding a minimum angle of rotation", the electronic control device recognizes the emptying of the waste container.

According to at least one further manufacturing model, after the emptying has been recognized, a locking device control signal is generated to release the locking device. In this way, the locking device again frees the opening for the insertion of garbage by the users of the now empty container.
