Abstract
A waste container for collecting recyclable materials such as glass or paper is provided with at least one level sensor to indicate when the container should be emptied. The level sensors 1a, 1b, 1c, 1d are photoelectric sensors and are connected to transmitter modules 5. The transmitter modules 5 telemetrically link the sensors to a modem 2 which sends data to a computer system 9. The modem may use a telephone network or email to communicate with computer system 9. The sensor periodically transmits a signal indicating the status of the container, which allows more efficient planning of emptying rounds.
Description
WASTE CONTAINER
This invention relates to waste containers more particularly to public waste containers of the type often used for collection of recyclable materials such as newspapers, cans and glass bottles and which are provided and emptied by public bodies.
It is well known for local authorities to provide public waste and recycling containers for use by the community. Such containers are often seen in the car parks of large supermarkets. At present, these authorities send collection vehicles at frequent intervals to check the level of materials in the containers and, where needed, empty them. The level of materials is checked manually, the vehicle driver peering through a hole in the container to ascertain the quantity of material present and judge whether the container needs emptying. Often there is no need to empty a container.
The cost of operating collection vehicle for emptying the aforementioned waste and recycling containers is, at the time of writing, of the order of ú2.51 per mile, thus it can be seen it is inefficient for these vehicles to be used to check levels of materials in containers which may not be full and which need not be emptied.
The present invention aims to provide for more efficient monitoring of materials levels in waste and recycling containers and collecting materials from full containers.
In accordance with a first aspect the present invention provides a system for monitoring the status of one or more waste or recycling containers comprising a photoelectric sensor secured to an inner surface of the or each waste or recycling container at a level at or below the maximum desirable fill level of the container the or each photoelectric Àeeeeeseee Àe sensor being telemetrically linked to a transmitter module which transmitter module is configured to transmit a signal indicating the status of the container.
The system may be configured to transmit a periodic signal indicating the current status of the container (eg full or empty). The period of the signal may, for example, be daily, weekly or monthly.
Alternatively or in addition, the system may be configured to emit a signal when a photoelectric sensor detects that the container is full and needs to be emptied.
The system may include one or more wireless modems through which signals are transmitted in the form of an automated e-mail or telephone message to an appropriate collecting body suggesting that a collection vehicle be dispatched.
Optionally, the photoelectric sensor may be angularly arranged so as to compensate for loads which do not have a uniformly flat top surface.
The sensor is desirably housed in a robust container so as to avoid damage to the sensor if contacted by materials being deposited in the container. The housing may, in addition be selected to be corrosion resistant.
Optionally, the system may include an individual transmitter for each photoelectric sensor. Desirably, a plurality of sensors may be telemetrically linked to a single transmitter.
For the purposes of exemplification, an embodiment of the invention will now be further described with reference to the following Figure in which; Figure 1 illustrates one embodiment of a system according to the invention.
c:.''.e c.e i.: À:e:.
As can be seen from Figure 1, a system according to the invention comprises a plurality of level detection modules la, lb, 1c, Id each comprising a photoelectric sensor 4 and a transmitter module 5 having an aerial 6. The transmitter modules 5 transmit signals indicative of the light levels detected by the photoelectric cell to a modem 2, the modem includes a module 7 which receives data from each of the transmitter modules 5, processes the data and in turn sends a signal indicating the status of a container (not shown) in which the sensor la, lb, 1c or Id is placed to a central computer processor 9. Data received from the modem 2 is translated and displayed via display device 10.
The following table sets out a specification for the various components of one embodiment of the invention. Others will no doubt occur to the skilled addressee without departing from the true scope of the invention.
