ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a liquefied raw garbage collection method and system, and more particularly, to a liquefied raw garbage collection method and system whereby collection of liquefied raw garbage can be performed efficiently by touring collection vehicles.
2. Description of the Related Art
Generally, collection of raw garbage is performed by a method wherein the date or day of the week on which a raw garbage collection vehicle tours around garbage collection points, is determined, and each household is requested to place their raw garbage at a predetermined collection point, early on the day on which the raw garbage collection vehicle passes by, for example. There is also another method wherein raw garbage is collected by previously arranged by telephone or the like so that the collection vehicle is requested to pass by a prescribed point at a prescribed date and time.
However, in methods where raw garbage is placed directly at garbage collection points, problems arise in that the garbage may be attacked by cats, crows, or the like, or it may produce unpleasant odours, before the collection vehicle arrives at the garbage collection point.
Therefore, in order to prevent the raw garbage from being attacked by cats, crows, etc., it is necessary to take measures such as providing a raw garbage collection container at the garbage collection point, placing a net over the garbage bags or the like.
However, in conventional methods using containers, nets and the like, such situations may sometimes occur that the quantity of raw garbage exceeds the storage capacity of the containers, or the generation of unpleasant odours cannot sufficiently suppressed. Hence, it causes problems to determine where garbage collection points are located because hygiene-related problems may occur in the neighborhood of the collection points.
Furthermore, if a large amount of raw garbage happens to be produced by household, then it must either request a another visit of the raw garbage collection vehicle, or the garbage must be stored in the household until the collection vehicle visits next time.
Since raw garbage will decompose with the passage of time, if the raw garbage is stored inside the household, problems arise with regard to hygiene, for instance, unpleasant odours are produced.
To solve the problems, a raw garbage collection system has been proposed, wherein raw garbage liquefying apparatuses are provided in distributed locations adjacent to respective households or the like, and the raw garbage liquefied by the raw garbage liquefying apparatus is collected and stored in highly sealed liquefied raw garbage storage tanks. Then, the liquefied raw garbage deposited in the liquefied raw garbage storage tanks is recovered periodically by touring collection vehicles, whereby raw garbage can be collected without dispersing unpleasant smells into the surrounding area.
By means of this raw garbage collection system, it is possible to place raw garbage into a raw garbage liquefying apparatus at any time, and hence generation of unpleasant odours due to decomposition of the raw garbage can be prevented, thereby providing a significant merits in terms of hygiene.
However, in the aforementioned raw garbage collection system, collection must be performed without fail before the amount of liquefied raw garbage accumulated inside the liquefied raw garbage storage tank of the raw garbage liquefying device exceeds the permitted amount.
If, as illustrated in

, the touring collection vehicle

visits every raw garbage liquefying devices

which need liquefied raw garbage to be collected therefrom and every raw garbage liquefying device

which do not need liquefied raw garbage to be collected therefrom, then it will make unnecessary collections, which is inefficient.
Moreover, since the touring collection vehicle

passes along the touring route a large number of times, the distance travelled by the collection vehicle is long, and the fuel consumed by the touring vehicles increases, thereby not only causing costs to increase, but also raising the amount of exhaust gas generated, which has a detrimental effect on the environment in addition to the economic aspects.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a liquefied raw garbage collection method and system whereby touring collection vehicles can collect liquefied raw garbage from the liquefied raw garbage accumulation tanks of raw garbage liquefying devices situated in a plurality of dispersed locations in an efficient manner.
The liquefied raw garbage collection method according to the present invention is a liquefied raw garbage collection method wherein the liquefied raw garbage accumulated respectively in a plurality of raw garbage liquefying devices situated in a plurality of distributed locations is collected by means of a plurality of touring collection vehicles; the accumulation state of the liquefied raw garbage in each of the plurality of raw garbage liquefying devices being monitored by a central station by exchanging information between the plurality of raw garbage liquefying devices and the central station; and the central station issuing collection instructions for the liquefied raw garbage from the plurality of raw garbage liquefying devices, to the plurality of touring collection vehicles, on the basis of the results of the monitoring.
With this configuration, it is possible to dispatch touring collection vehicles only to those raw garbage liquefying devices which require collection of liquefied raw garbage, and hence highly efficient raw garbage collection can be achieved.
Here, it is possible to adopt a configuration wherein the central station confirms the respective current positions of the plurality of touring collection vehicles by exchanging information through radio communications with the plurality of touring collection vehicle; and issues collection instructions for the liquefied raw garbage from the plurality of raw garbage liquefying devices to the plurality of touring collection vehicles, on the basis of the respective current positions of the plurality of touring collection vehicles thus confirmed.
With this configuration, it is possible to issue a collection instruction to a touring collection vehicle that is near a raw garbage liquefying device from which liquefied raw garbage is to be collected, and hence fuel consumption and the time required for touring collection can be reduced.
Furthermore, it is also possible for the central station to confirm the respective current liquefied raw garbage collected amounts of the plurality of touring collection vehicles by exchanging information through radio communications with the plurality of touring collection vehicle; and to issue collection instructions for the liquefied raw garbage from the plurality of raw garbage liquefying devices to the plurality of touring collection vehicles, on the basis of the respective current liquefied raw garbage collected amounts of the plurality of touring collection vehicles thus confirmed.
With this configuration, it is possible to issue a collection instruction to a touring collection vehicle which is situated near to a raw garbage liquefying device requiring collection and which is capable of collecting the whole amount of liquefied raw garbage accumulated therein.
Moreover, it is also possible to collect the whole amount of liquefied raw garbage by issuing collection instructions to a plurality of touring collection vehicles located near to the raw garbage liquefying device requiring collection.
Furthermore, it is also possible to adopt a configuration wherein the raw garbage liquefying devices comprise liquefied raw garbage accumulated amount detecting means for detecting the current accumulated amount of liquefied raw garbage in the raw garbage liquefying device, the liquefied raw garbage accumulated amount detected by the liquefied raw garbage accumulated amount detecting means being notified to the central station at pre
