- Rubbish bins are also known as litter bins, trash cans and garbage cans.
- litter bins trash cans and garbage cans.
- garbage cans waste bins
- these bins are fixed in location and emptied on a regular basis which depends on the extent of use of the bins in an overall sense. Typically this is weekly or daily.
- each bin in an area will be used in differing amounts depending on the location of the bin within the collection area, special events and other factors.

Abstract
A monitoring system comprises a plurality of monitoring stations disposed in or associated with a respective rubbish bin housing or surround.

Description
- The present invention relates to a distributed monitoring system based around rubbish bins and management of the collection of rubbish from rubbish bins.
- In areas of higher density population, such as residential/office, retail and entertainment precincts, municipal organisations, such as local governments provide public rubbish bins for disposal of rubbish. Rubbish bins are also known as litter bins, trash cans and garbage cans. Traditionally these bins are fixed in location and emptied on a regular basis which depends on the extent of use of the bins in an overall sense. Typically this is weekly or daily. However each bin in an area will be used in differing amounts depending on the location of the bin within the collection area, special events and other factors. Aside from one-off collections during or after a special event at a specific location, the timing of collection from the bins, generally, does not vary. As a result the frequency of collection is usually sub-optimum and the frequency does not account for the waste level in each individual bin. This can result in bins that are not full being emptied unnecessarily and bins overfilling. In turn this results in poor use of the bins, the creation of litter and inefficient management of waste collection from the bins.
- It is noted that rubbish is also known as trash, waste, refuse, litter, and garbage.
- The present invention seeks to provide more effective waste collection.

Further there may be more than one sensor as will be described further below, including a sensor for measuring an environmental condition in the vicinity of the bin. - A processor 42 (housed in housing 30) receives a signal from the sensor(s) 26 and in this embodiment determines the level of
rubbish 32 in the bin based on the received signal as one or more discrete representations of the level ofrubbish 32 in the bin. For example the discrete representation could be a binary the bin is “empty” or “full” (“full” might mean near full as opposed to literally so as to avoid rubbish spilling over and “empty” is not full) or trinary indication such as “empty”, “half-full” and “full”. Other discrete levels can also be used, such as a level out of 10. - The
processor 42 also determines environmental factors about the bin or its environment from the one or more other sensors. - The
processor 42 controls an output for indicating the level ofrubbish 32 in the bin and environmental factors. In this embodiment the output is atransmitter 50 inhousing 30 which transmits data representing the level from anantenna 34 as aradio transmission 36. The radio transmission may be for example by WIFI, cellular network, “ZigBee” network, or otherwise. Alternatively thetransmitter 50 may make a wired transmission.

These measurements can be stored in thememory 46. In an embodiment theclock 44 is also used to determine the passage of a second predetermined amount of time, such as 6 hours, after which the stored measurements are transmitted. Theprocessor 42 interfaces with thesensor 26 and thetransmitter 50 via an I/O interface 48. The elements of thedetector 40 are shown coupled by a system bus or other mechanism. - In an embodiment the transmission used Internet Protocol packets, but other protocols may be used.
- In an embodiment the processor is configured to cause the transmitter to transmit the level signal and/or environmental factors when the level of rubbish in the bin reaches predetermined level or when one or more of the environmental factors meets one or more conditions, such as for example the bin is being moved, the bin is on or near fire or pollution levels are above a certain level.
- In an embodiment the processor is configured to receive a poll signal prompting the
processor 42 to receive the sensor signal and to cause the transmitter to transmit the level signal. - In an embodiment the transmitter is configured to transmit an identifier of the bin with the level signal. Generally each bin will be allocated a number and this can be used as the identifier. Alternatively a GPS reading may be used.
- In an alternative or in addition to transmitting the rubbish level the level may be output to a visual indicator mounted on the bin, such as a display or one or more lights.
- The
detector 40 may comprise other detectors, such as a pollution detectors, a temperature sensor (such as DHT22 or BMP085)), a UV sensor (such as UVI-01), a noise level sensor (such as a microphone), a humidity sensor (such as DHT22), an air pressure sensor (such as BMP085), a light sensor (such as an LDR with an ADC such as MCP3008), a particle sensor, a “door open” detector or a near field identification detector. Each of these detectors comprises anothersensor 226 of the appropriate type which generates a signal representing the type of thing detected which is received and processed by theprocessor 42. Theprocessor 42 may also transmit the signal or may only transmit a signal when certain criteria are met. These example detectors will be described in more detail further below. Pollution detectors may include gas and or particle sensors, such as carbon monoxide (such as MiCS-5525), carbon dioxide, nitrogen dioxide (such as MiCS-2710), ozone, sulphur dioxide measuring devices. - Referring to

This may be for example every 15 min.Sensor 26 is read at 102. Theprocessor 42 performs a check of whether rubbish is detected at 104. If the distance to the level of the rubbish is less than a first predetermined amount, for example ⅓ of the height of the bin, then it registers as not detected, that is, “empty” (which differs from literally empty). If the reading is “empty” the process end. For housekeeping purposes the empty reading may be recorded in thememory 46. - Then if more than the first predetermined amount is detected, for example ¼ of the height of the bin, but less than a second predetermined amount, for example ⅔ of the height of the bin, then it registers as “half-full” as indicated by 106 and this reading is recorded in the
memory 46. - If more than the second predetermined amount is detected, for example more than ⅔ of the height of the bin, then it registers as “full” as indicated by 108 and this reading is recorded in the
memory 46. - In an embodiment until the next time the bin is emptied the first time the level gets to “half-full” and “full” the level and bin identifier (and in some cases a time stamp) are collected at 110 and transmitted at 112 to a
receiver 162 of awaste management system 16 or to a device such as a device worn by the waste collection worker or mounted to awaste collection vehicle 185. - Referring to
FIG. 5 there is amethod 120 of collecting information on bin levels, which commences with thesensor 26 taking a reading atstep 122 and then checking 124 whether rubbish has be detected. If it has not been detected the process returns for another check after a suitable period of time. A similar process can be used by other types of detector. - If rubbish has been detected the amount is recorded. In this embodiment the level is not categorised and the measured level is sent. The
transmitter 28 preferably wirelessly establishes communication with a wireless communications network at 126 and sends the information to themanagement system 16 at a variable time, such as daily or twice daily, as indicated by 128. The information transmitted to themanagement system 16 at 130 included the level indication and a location or bin identifier, such as GPS co-ordinates, or a bin identification number. Themanagement system 16 may categorise the level (eg empty, half-full or full) or retain the level as a measurement. - Referring to
