The present invention relates generally to the monitoring, control and optimization of a waste pickup service. More specifically, the present invention relates to a system for monitoring the amount of waste picked up from each waste container by a plurality of garbage trucks, alerting when irregularities occur in the process, aggregating this information into a locale-based waste pickup situational picture, analyzing this information and offering, based on the analysis, an optimized waste pickup solution for that locale.
Modern life style creates increasing amounts of waste to be picked up from homes, businesses and markets, all in challenging urban environments. The locale waste pickup service is complex and includes: waste containers, in various sizes and shapes, portable garbage compactors, a fleet of garbage trucks picking up garbage from these waste containers, local and national garbage dumpsters to where the waste is carried to, and of course the employees giving this service to residents.
The current waste pickup service is lacking in concrete data, commencing with information on the amount of garbage collected from each waste container along waste pickup routes and continuing with lack of information on the location of the collected waste containers, the date and time of the pickup, the time it took to collect them in each zone of the locale and the performance of the collection process. Lacking in basic data, managers and locale decision makers fail in successfully managing and optimizing the waste pickup service. Without this basic building block, decision makers cannot monitor the waste pickup service, are not alerted when irregularities occur in the process and cannot construct an aggregated waste pickup service situational picture for the locale under their responsibility, cannot analyze the situation and cannot reach a more optimized solution.
An example can be a street with various residences, one of them with a higher waste production rate than the others. The garbage collecting truck visits this specific street three times each week. If information were to be gathered, on the amount of garbage collected from each of the residence's waste containers, decision makers could come up with a possible solution of adding an additional waste container to the higher rate producing residence, and limiting visits by the garbage truck to twice a week, thus saving money, energy and lowering pollution.
There is thus a need in the art for a new method and system for the monitoring, control and optimization of waste pickup service in urban environments.

Volume sensor 520 is an active sensor with a transmitter section 522 and receiver section 524. The transmitter section 522 illuminates the truck hopper and the volume is measured by the reflections from the garbage in the truck hopper.
In an exemplary embodiment of the invention, transmitter section 522 transmits Infra-red (IR) radiation and the IR emitting component is IR LED, IR Laser or the like. The receiver section 524 in this case is IR camera or any other IR detector.
In another exemplary embodiment of the invention, transmitter section 522 transmits ultrasound waves (US) and the US emitting component is a speaker, a piezoelectric vibrator or the like. The receiver section 524, in this case, is a microphone, a piezoelectric sensor, or the like.
In yet another exemplary embodiment of the invention, transmitter section 522 and receiver section 524 use different electromagnetic frequencies bands, such as radio waves, or other sound wave bands, such as infrasound.
In an exemplary embodiment of the invention, a plurality of volume sensors 520 are used. Multiple volume sensors may increase the field of view. Multiple volume sensors may be used to increase the accuracy of the volume measurements. Optionally, volume sensors 520 may use different type of radiation or waves (e.g. electromagnetic waves or sound waves) or different frequency bands.
Visible light camera 530, is used to identify the waste container type. As used herein, the term “waste container type” means the size and shape of the waste container. Usually, the waste pickup service uses only a few types of waste containers that are different mainly in their container capacity. As used herein, the term “capacity” means the maximum volume of the waste container. Controller 540, by analyzing the visual information from visible light camera 530, identifies the type of the container that is currently being emptied. Identifying the type of container from possible types used in the waste pickup service determines the capacity of the waste container.
Optionally, identification includes the waste container purpose and waste container ID. As used herein, the term “waste container purpose” means the planned waste content of the waste container. The planned waste content may be glass, plastic, paper or the like for the purpose of recycling or separation between bio waste and none-bio waste or the like. The waste container purpose is usually identified by the color of the waste container. In some cases, the type of the waste container has a one to one mapping with the waste container purpose while in other cases the same type of waste container is used for different purposes and only a color code marks their purpose.
As used herein, the term “visible light camera” means a camera that can sense light in at least a portion of the visible spectrum, i.e., wavelengths from about 390 to 700 nm. The term “visible light camera” also applies to cameras that sense light spectrum that in addition to the at least a portion of the visible light cover wider spectrum either to the shorter wavelength (ultraviolet light) or to the larger wavelength (infrared light).
As used herein, the term “waste container ID” means the specific waste container. Container ID may be identified by a printed tag or sticker on the container. The tag may be a unique ID number or, in many cases, the address of the house where the waste container is deployed.
In an exemplary embodiment of the invention, controller 540 identifies the container ID by analyzing the written or printed marking of the waste garbage using the visual information from visible light camera 530. Additionally or alternatively, the ID is analyzed using OCR algorithms to identify printed and hand written texts. Additionally or alternatively, the waste container has an RFID tag and the controller 540 reads the waste container ID using an RFID reader.
In an exemplary embodiment of the invention, identification of the waste container, is done using image processing algorithms running on data of still images taken from visible light camera 530. Additionally or alternatively, the image processing is done on the video stream during emptying of the waste container. Optionally, identification of the waste container type is performed by comparing the imaging date to a pre-loaded bank of waste container images.
In an exemplary embodiment of the invention, controller 540 calculates the waste volume emptied in each waste container by subtracting the hopper volume measurement taken before the waste containers is loaded to the hopper, from the hopper volume measurement taken after the waste containers is loaded to the hopper.
In an exemplary embodiment of the invention, controller 540 is configured to measure a waste volume for each waste container, when a plurality of waste containers is loaded together in the same load cycle of the garbage truck.
In an exemplary embodiment of the invention, controller 540 is configured to measure a waste volume of bulk waste.

Next, step 650, processes all the data and compute the waste volume that was in the waste container. The volume of waste that was in the container is the difference of the volume in the hopper after and before loading the waste from the container to the hopper. Note that, in general, the hopper is cleared and the waste is compacted and moved to the truck's container after several cycles of loading. However, since the measurement was made before and after each loading cycle, the waste volume in the waste containers was measured accurately.
In an exemplary embodiment of the invention, processing waste pickup information is performed by at least subtracting, the waste volume in the hopper measurement taken before the waste containers is loaded to the hopper, from the waste volume in the hopper measurement taken after the waste containers is loaded to the hopper.
Next, in step 660, reporting the reading of the volume of the specific waste bin is performed. The reporting may be done online by sending the information by communication means to the waste pickup system server, or offline by storing the information locally and fetching it later when the truck end its route. Step 670 checks if the route of the truck is finished. If not, the measurements continue by jumping back to step 620 and reporting additional volumes of the other waste containers emptied during the truck's route, until all waste containers planned for the truck's route have been picked up.
Reference is now made to
The term “bulk waste” means any waste that is too large to be accepted by the regular waste containers or any waste that from any other reason is loaded directly to the hopper without using the waste containers.
The term “load cycle” means a single operation of the lift system where one or more waste containers are lifted, flipped, emptied and brought back to their initial position together.
Bulk waste, either loaded manually or loaded using a dedicated crane, such as a knuckle-boom crane, is automatically measured. The measurement of bulk waste loaded is done without any intervention or burden to the garbage truck crew.
After the truck is located in step 622, and just before the loading, step 624 performs a measurement of the current waste volume in the hopper as well as a measurement of the distribution of the waste. In parallel, step 626 performs identifying of the number of waste containers that are attached to the lift. Identification of the presence of bulk waste being loaded 628 is performed as well. Now the load cycle starts and the waste from all sources is piled up in the hopper. To accurately estimate the contribution of each source, step 642 tracks the dynamics of the waste pile accumulation in the hopper. Steps 642 and 644 measure the volume of each waste source based on the dynamics of the waste distribution in the hopper. The calculation is based on the locality of the waste pile in the hopper, for each waste source, taking into account the overlapping effect of diffusion of each waste source pile towards the other source piles. The final measurement is provided after the load cycle ends. During the load cycle, the location, date and time are recorded as well in step 634. In addition, each waste container is identified by at least one of or any combination of the waste container specific ID, type or purpose. All the data of the load cycle then processed and aggregated in step 652. Next, in step 662, the data is reported. Then in step 682 the system prepares to start the next measurement.
In an exemplary embodiment of the invention, the waste container purpose is identified in step 632 by the color of the waste container.
In an exemplary embodiment of the invention, container ID is identified by interpreting a visual marking on the waste container. Alternatively, the identification is made by electronic tagging signals, e.g., using RFIDs.
In an exemplary embodiment of the invention, the waste volume is calculated by setting a grid of adjacent different areas on the hopper and the total loaded volume is the integration of differences in the measurements of all points in the grid, and the specific loaded volume of each source is a weighted integration of the difference, wherein in each point on the grid, each source is assigned a contribution weight between 0 to 1 to indicate the volume contribution of each source to each grid point (each different area in the hopper).
In an exemplary embodiment of the invention, the waste measurement system is configured to calculate the waste volume of a waste container when the emptying of the container is done in two steps. A two steps scenario occurs when during emptying of a waste container the hopper become full. In this case, the garbage truck crew stops the loading of the hopper, compacts the hopper contacts, and then continues with loading the rest of the waste in the container into the now empty hopper. The measurement algorithms (the method) of the controller automatically identifies the two step scenario and accumulates the two partial volumes collected in each load cycle into a single reading of the waste volume emptied from the waste container.
In an exemplary embodiment of the invention, the waste measurement system is configured to measure bulk waste volume loaded separately to the hopper.
In an exemplary embodiment of the invention, the waste volume is calculated conditioned upon reading of a weight measurement received from a sensor located in the truck hopper.
In an exemplary embodiment of the invention, the reporting is done online with a cellular network. Additionally or optionally, the information is stored in a local storage, e.g., solid state disk drive, and fetched later on, using wired communication, e.g., USB cable.
Reference is now made to
The information regarding locations is processed by a location service module 484 and inserted into a database module 488. The database module is implemented using a standard open source MySQL database software package. The waste bin information is directed to an analysis service component 486. The analyzed data is stored in database 488 as well.
In parallel, online algorithms run in notification services 492 to check for irregularities during the waste collection procedure. The notifications are transferred to a UI module 498 that presents the notifications to the user. The system collects the data about the waste for each container. The system computes a waste generation rate for each specific container. Integrating all rates together creates a dynamic waste generation rate map for the entire garbage collection area. These maps are used by the optimization services module 494 in order to solve the optimization problem under the desired optimization criteria.
Using analysis service 486, the waste generation rate map, and conditioned upon the user's policy, optimization service module 494 produces recommendations for the waste collection procedure, e.g., the schedule and routes of trucks 110 in the truck fleet.
UI module 498 provides the interaction with the system users. In an exemplary embodiment of the invention, the user interface is web based and the user can login to a dashboard. In the dashboard the user can see live maps of waste collection plans and status, truck current and history locations, routes, waste containers information, statistics of various information, and notifications about problems that occurred during the waste collection procedure. The user can generate various reports using the report generator module 496.
An API service 499 enables sharing (receiving and/or transmitting) information with other IT systems such as city management system and the like. API service 499 may receive alerts from other IT servers such as blocked road events and the like.
