Description

The present invention relates to an electronic system for collecting

  data to enable monitoring and management of the use of the filing capabilities of one or more waste disposal centers, and furthermore, to impute the deposits to each user. It also concerns a waste

  earth equipped with such an electronic system, and a set of a plurality of such waste management managed from a common control to which they are electronically connected.

  It is known that, commonly, a refuse collection comprises a plurality of dumpsters for waste deposits, each bucket being generally intended for a category of waste (metals, plants, rubble, paper and cardboard, etc.) and having a determined capacity. loading.

  The management of such a site is entrusted to a caretaker who takes care of welcoming the users, directing them and monitoring the filling of the skips. The custodian is responsible for recording user loading quantities for billing and arranging the removal of full trucks by truckers.

  To do this, the guard maintains a register in which, after visually evaluating the amount of loading, it manually reports the type and estimated weight of the load deposited by the user as well as its coordinates on the pages of the register.

  When he considers that the total estimated load of a skip reaches its maximum filling capacity, he contacts a telephone company by telephone to request that a collection truck be sent to remove the skip.

  This empirical management method has the disadvantage that the loading weights are not evaluated accurately. This method does not make it possible to follow correctly the loading weight brought by each user and to accurately impute the cost of treatment to each of them.

  In addition, because of the imprecision of the evaluation of the total loading of the buckets, the unavailability of the pick-up trucks when several waste pickups make use of the control, and the time which elapses between the call of a guardian and the arrival of the truck-collector, one notes a bad rotation of the buckets, the buckets being able in particular to be excessively filled, which generates deposits outside the skips or the savage deposits.

  The object of the present invention is to overcome the above drawbacks by providing an electronic data collection and management system making it possible, on the one hand, to manage the use of the deposition capacities of one or more waste centers and, on the other hand, to impute the deposits to each user.

  An object of the invention is to know at any time the loading in progress of each bucket exactly, to accurately quantify the deposits made by each user and to assign each of these deposits to the corresponding user.

  Another object of the invention is to manage a network of several waste sites, from the outside from a centralized control room, even in the absence of guards.

  To this end, according to the invention, an electronic system for collecting and managing data for a refuse collection of the type referred to above, is remarkable in that it comprises sensors able to measure the loading of each bucket, means of link between said sensors and a central office, and centralized data processing means relating to the loading meters of the buckets.

  With such a system, one can know precisely and at any time the measurement of the total load of each bucket, which optimally manages the use of the capacities of the buckets and their rotation. In addition, it is possible to know precisely the amount of waste deposited by a user and to be able to accurately impute the deposits to each user.

  It is expected that the data processing means are able to compare the load measurements of each bucket with respect to their loading capacity and to determine their rate or state of loading.

  Advantageously, the system then comprises means for visualizing the loading rate or for signaling the filling state of the skips.

  Thus, the site manager or the control room is able to follow at any time the rate or the filling status of the refuse collection bins, so as to organize and trigger the rotation of the collection trucks to remove the buckets in good time. .

  It is further provided that the data processing means are capable of calculating the amount of waste deposited in a skip by a user based on bucket loading measurements made before and after the deposit. performed by the user.

  Advantageously, the processing means are then able to impute the amount of waste deposited by the user to the account of the latter.

  To do this, it is planned to identify the users, in particular using contactless radiofrequency identification badges.

  As a result, the electronic system according to the invention comprises a plurality of equipment provided with identification means, among which: an identification terminal forming part of an access control equipment for the refuse collection; identification terminals of the users respectively disposed of each bucket.

  Thus, each user must identify himself, in particular by means of his contactless radiofrequency badge, at the entrance to the waste disposal site, and then when placing his load in front of each bin assigned to a category of waste, which allows 'accurately impute the quantity and type of waste deposited to the identified user.

  The figures of the appended drawing will make it clear how the invention can be realized. In these figures, identical references designate similar elements.

  Figure 3 is a perspective view of a weighing equipment of a bucket implemented in the system according to the invention.

  FIG. 4 is an elevational view of a user identification and deposit authorization terminal used in a system according to the invention.

  FIG. 5 is a diagram of a network comprising several drops connected to a common control unit with the electronic system according to the invention.

  The establishment of a refuse collection 1 generally comprises, as illustrated in the overview of Figure 1, an elevated land embankment land 2, provided with access ramps 3, 4 and coated to serve as a parking area. parking for users' vehicles (light tourism vehicles).

  The flanks of the embankment 2 are cut by slots 5 (pits) arranged in crenellations or on the cob, in which are deposited several skips 6 used for the selective deposition of the waste, each skip 6 receiving a category of waste (metals, papers and cardboard, plants or green waste, plastics, glass, rubble, etc.). The site 1 is surrounded by a traffic corridor 7 reserved for the truckers' maneuvers who come to proceed with the removal of the buckets 6 once they are fully loaded. The entry 8 and the exit 9 of the trucks loaded with the collection of the buckets are separated from the entry 3 and the exit 4 allocated to the light vehicles of the users.

  A room 10 for use by the waste management managers is generally built at the entrance to the site 1, as shown in Figure 1, between the access ramps 3 and output 4 of the light vehicles of users.

  In order to know precisely the loading of the buckets and to assign exactly the loads deposited by the users to each of them, according to the principle of the invention, it is planned to implement, on such a site, an electronic system 11 of data collection and management comprising central equipment 12 having centralized data processing means 13 and connected to a plurality of equipment 14, 15, 16, 17, 18 distributed over the site 1, as illustrated in the general view of the Figure 1 and the block diagram of Figure 2.

  The system 11 comprises, in the first place, equipment 14 for weighing the buckets, each bucket 6 being placed on a weighing equipment 14 placed on its location 5.

  The system 11 comprises, secondly, signaling terminals 15 disposed respectively with each bin 6, on the area of the embankment 2 where users' vehicles access, these terminals 15 being used to signal the authorization or not to deposit a load in the corresponding bucket 6 and identify the user during the deposit.

  In addition, the system 1 1 preferably comprises equipment 16 installed at the entrance 3 of the site and used to identify the users and to control the access of the vehicles to the entrance 3 of the site 1, as well as accessory a barrier equipment at the outlet 4 of the site 1.

  The system may further comprise equipment 18 installed at an access 8 of the traffic lane 7 reserved for heavy goods vehicles, which equipment 18 serves to control the access of the trucks responsible for collecting the skips 6 and possibly to identify the truckers or service providers in charge of collection.

  As shown in the block diagram of FIG. 2, the various aforementioned equipments 14, 15, 16, 17, 18 are connected to a central equipment item 12 which comprises means 13 for processing the data coming from this equipment and relating to the measurements of the weight of the equipment. loading of each bin 6 as well as the identification of users. This central equipment 12 is advantageously placed in the premises 10 at the disposal of the site managers 1 or, by extension, out of the site, in a control unit which manages a network of several waste disposal centers (not shown).

  The central data collection and management equipment 12 is therefore connected to the weighing equipment 14, to the signaling terminals 15 of the buckets 6 and to the access equipment 16, 18 by connection means 19, such as connecting cables containing lines for transmitting identification and weighing data, operating control lines and possibly power lines.

  Figure 3 shows an embodiment of a specific weighing equipment 14 of a bucket 6 for accurately measuring the load weight contained in said bucket.

  The equipment 14 comprises four weighing sensors 20 located inside the four corners of the rectangular location of the bucket 6, the sensors 20 supporting a platform frame 21 adapted to receive the bucket 6.

  The sensors 20 are formed for example by dynamic weighing cells comprising an electronically measured hydraulic cylinder device disposed between horizontal flanges, as illustrated in FIG. 4.

  The frame 21 comprises a rigid stabilization structure for weighing measurements comprising two transverse bars 22 each fixed on the upper flange of two respective sensors 20 so as to join them in pairs, the two transverse bars 22 themselves being secured by a profiled axial beam 23. The frame 21 further comprises two longitudinal boxes 24 resting on the transverse bars 22 and arranged along the long sides of the rectangular location.

  The two longitudinal boxes 24 have a flat top surface lined internally by two guide rails 26 so as to advantageously form two rails 27 for the rollers 28 and the stiffening ribs 29 of the skip 6, as shown in FIG. in Figure 3.

  Such platform weighing equipment 14 facilitates the engagement of the bucket 6 and allows it to be supported permanently while making stable and accurate measurements of its loading weight.

  To format the various analog measurement signals from the four sensors 20 composing the weighing equipment 14 of a skip 6 and to provide an overall measurement of the total weight of the skip, in the form of digital data, the outputs of the four sensors 20 are connected to a common electronic data acquisition circuit 30.

  The electronic data acquisition circuit 30 carries out the operations necessary to acquire the weak analog signals coming from the sensors and to supply at its output digital data representing the overall measurement of weighing corresponding to the weighted sum of the partial weighing measurements of the four sensors according to the techniques used in physical instrumentation (power and polarization of the sensors, amplification and sampling of the weak analog signals of the sensors, conversion into digital data, weighting and addition).

  As indicated in FIG. 4, this interface electronic circuit 30 connecting the outputs of the four sensors 20 to an input port 19 of the central equipment 12 of the electronic system 11 according to the invention is advantageously disposed of. interior of a signaling terminal 15 which is located near the location 5 of the body 6.

  Figures 1 and 2 show that several terminals 15 are located on the upper level of the embankment 2 to which users access, each terminal 15 located near a corresponding bucket. The terminal 15 can be installed for example at the corner of the bucket 6 most accessible to users.

  As shown in Figure 4, the terminal 15 is formed of a weather-resistant metal housing and can accommodate multiple electronic circuits 30, 35, 36.

  Terminal 15 has a reduced horizontal section to occupy a small footprint area.

  The terminal is raised to man's height and comprises signaling means 31, such as bi or tri-color lights at its upper part. The terminal furthermore advantageously includes an indication of a category of waste in the form of, for example, sign, lettering, display of pictograms, luminescent characters, light signals, etc., enabling users to know to which category of waste the bucket is reserved (metals, vegetables, rubble, paper and cardboard, etc.).

  The traffic lights 31 serve to indicate to the users whether the skip 6 is available to deposit a load of waste.

  Thus, when the bucket 6 is placed empty on the weighing equipment 14 and as the measurement of its loading weight is less than its filling capacity, the traffic lights 31 are put in a state (green light for example) indicating to his user that he is authorized to deposit a load.

  When the loading of the bucket 6 reaches its full filling capacity, the traffic lights 31 pass to another state (red light for example) indicating to the user the prohibition to deposit a load.

  The change of state is triggered when the electronic data acquisition circuit 30 indicates that the load weight measurement of the skip 6 exceeds a programmed load weight threshold at the central equipment 12. The change status can be controlled directly by the electronic data acquisition circuit 30 or from the central equipment 12, either automatically or manually, through a manual control available to the custodian of the site or the control room.

  As shown in FIG. 4, the terminal may include a horn 32, such as a loudspeaker, alarm or siren. The terminal 15 is further connected to one or two electromagnetic detection loops 33 implanted under a parking area 34 near the corresponding bucket 6 and serving as means for detecting the presence of a vehicle.

  Thus, when a vehicle comes to park near the terminal 6 while the traffic lights 31 indicate a prohibition to deposit a load (red light for example), an electronic detection circuit 35 detects the presence of the vehicle and can trigger a alarm 32 to remind the user that the skip 6 is not available and possibly attract the attention of the site keeper 1.

  The terminal 15 further comprises, according to the invention, identification means 36 for each user, such as a remote reading device for radiofrequency identification badges (contactless cards).

  Such a reading device 36 comprises an electronic circuit and a radiofrequency transmission / reception antenna, for example at a dedicated frequency of 13.56 MHz, making it possible to remotely read and decode the identification data contained in each badge or map.

  When the traffic light 31 indicates the authorization to deposit a load in the bucket 6 and a vehicle comes to park on the parking area near the bucket, the electronic detection circuit 35 detects the vehicle and then triggers the activation of the identification means 36 of the users.

  At the same time, the electronic data acquisition circuits 30 tare the weight of the bucket 6, that is to say a sampling of the measurement of the total weight of the bucket 6 before the deposition of its load by the bucket 6. 'user. The data corresponding to this first measurement of the loading weight of the skip 6 are transmitted to the central equipment 12 and recorded.

  As soon as the user has presented his identification badge 37 to the reader 36, the identification data decoded by the reader 36 is also transmitted to the central equipment 12.

  As shown in Figure 4, the terminal 15 may include a digital display 38 to indicate to the user the weight of waste he has deposited.

  Thus, while the user is depositing his load, the electronic data acquisition circuit 30 makes measurements of the weight of the bucket 6 to which the tare is subtracted, that is to say the first measurement of the weight of the bucket, to display the exact weight of waste deposited individually by the user, these data being transmitted parallel to the central equipment 12.

  Optionally, the terminal 15 may include a custom printing device (not shown) for editing a statement of the weight of waste deposited by the user at the request of the latter when he presses on said command after having performed his deposit.

  More generally, the presence detection loop 33 of a vehicle advantageously makes it possible to detect the departure of the vehicle once the user has deposited his load.

  The electronic detection circuits then trigger a new measurement of the total weight of the bucket, that is to say a measurement of the total loading weight after the user has deposited his individual load. The difference between this new measurement and the first measurement, that is to say between the loading weight after the deposit of the user and the tare carried out before this deposit, makes it possible to establish exactly, by subtraction, the weight of waste deposited individually by the user.

  These data of measurement of the loading weight before and after the deposit of the user (or their difference) are transmitted to the central equipment 12 which records in a file all the data corresponding to the type and weight of deposited waste. by the user with his identification data, as well as possibly the data relating to the place, date and time of the user's visit.

  As a result, the centralized equipment 12 comprises electronic means 13 hardware and / or software (hardware / software) such as a central computer unit provided with a display monitor 38, computing and data storage means and programmed using a computer program dedicated to the processing of these data.

  The equipment 12 may be further connected to an electronic payment terminal 39 and to printing means 40 for the purpose of billing the services of the waste disposal facility to the users concerned.

  As a result, the data processing means of the central equipment have the function, among others: to record in a permanent memory medium, for example in a file dedicated to the user identified by its identification data, the data relating to the weight and type of waste deposited by said user at each of his visits, together with the place, date and time of said visits; to edit invoices on behalf of each user, including identification data, place, date / time of visit and indicating the type and exact weight of waste deposited and the fees charged; transmitting the billing data to the electronic terminal 39 to effect the payment of the benefits; to update the loading weight totalized by each bucket 6; comparing the loading weight of each bucket 6 with respect to its nominal loading capacity to determine its loading ratio or its filling state; displaying the loading rate or the filling state of each bin 6 on the display screen, as well as possibly the weight of waste deposited individually by the user present; when the total load weight of a bucket reaches or exceeds its nominal loading capacity (filling rate close to or greater than 100%), alert the guardian or the control room to initiate a request for the dispatch of a heavy truck loaded with collect the skip 6 concerned, and transmit a control signal state change control 31 (red light), to prohibit any new deposit.

  The means 13 for collecting and managing the data can thus make it possible to monitor and manage in a centralized manner the use of the storage capacities of one or more waste disposal centers and to impute the deposits to each user.

  In addition, to prevent access by unauthorized persons, access to the site of the waste disposal center are equipped with access control equipment 16 connected to the central equipment 12 of the electronic system 11. Access control equipment 16 can be used to check user identification and regulate vehicle access.

  FIG. 1 shows for example that the entry 3 of the site 1 reserved for the light vehicles of the users, near the place 10 of the guards, has access control equipment 16 including an identification terminal 39, a barrier of access 40 and traffic lights 41 bi or tricolor for users.

  As diagrammatically shown in FIG. 2, the user identification terminal 39 comprises a reader 42 remote from the radiofrequency identification badges 37 (contactless cards) of the same type as those of the signaling terminals 15 placed near the buckets 6.

  The identification terminal 39 is connected to a device 43 for maneuvering the access barrier 40 whose opening and closing maneuvers are controlled directly by the identification terminal 39 or by the central equipment 12.

  The signal lights 41 bi or tricolor are installed near the entrance 3 of the site 1, for example near the access barrier 40 and connected to the identification terminal 39 or the central equipment 12 to indicate to the users the possibilities of access and regulate access to the site (free access, waiting, access impossible for example).

  The access equipment can be connected to two detection loops 44 and 45 of vehicles implanted under the access paths respectively at the entrance 3 and at the exit 4 of the site 1, to detect the arrival and departure of a vehicle and count the number of vehicles entering / exiting, in order to regulate the number of vehicles present on the site.

  Another barrier 17 may be disposed on the exit route of the site, the operating device of this exit barrier 17 being triggered when the loop 45 detects the passage of a vehicle towards the exit 4.

  Such access control equipment advantageously makes it possible automatically to check that persons who want to access the site are provided with their identification badge and allow users to access the site even in the absence of a guardian (public holidays ).

  In use, therefore, the user presents himself with his vehicle at the entrance 3 of the site 1, the barrier 40 is closed and the signaling light 41 indicates the access possibilities (red, green, orange / flashing light corresponding to impossible access, free, waiting, for example).

  The detection loop 44 of the access control equipment 16 detects the presence of the vehicle and activates the reader 42 of the identification badge 37 of the user. When the user presents his badge 37, his identification data are decoded by the reader 42 and transmitted to the data processing means 13. If the user does not have a badge or in the event of a malfunction, a call button and an intercom allow the user to contact the guard or the control room, to obtain a manual access authorization or a temporary access badge. Once the user has been identified and authorized to access the site by the central equipment 12 or by the managers, the equipment 16 triggers the device 43 for opening the access barrier 40. the user is registered by the management means 13 of the central equipment 12 with the number of the badge 37, and the indications of place, date and time of the visit.

  Once the vehicle has entered the refuse collection, the user goes to a bucket 6 according to the category of waste he just drop and indications of the signaling terminals 15 placed with the buckets (display category of waste allocated to each bin and green / red traffic lights indicating the authorization or not to deposit a load).

  When the vehicle stops at the place 34 provided for unloading in front of the bucket chosen by the user, the detection loop 33 of the signaling terminal 15 detects the presence of the vehicle and the user must identify himself with his badge. 37 at the bollard, before proceeding to unload.

  The terminal 15 disposed near the bucket 6 records before and after the deposition of the load by the user the total weight of the bucket 6 measured by the sensors 20 of the weighing equipment 14 disposed under the bucket 6 and determines by difference the weight of waste deposited by the user.

  Once its load deposited, the user can restart the operations in front of other skips according to the category of waste that he must deposit.

  These data, total weight of each bin 6, weight and type of waste deposited by the user and identification of the user, are transmitted to the means 13 of data processing 4 to register the deposits, impute each deposit to the corresponding user, follow the filling status of the buckets and trigger the sending of the collection trucks.

  Once these operations are completed, the user goes to the exit 4 of the site 1, where the billing 40 and the payment 39 are established.

  At the exit 4, the detection loop 45 detects the passage of the vehicle and triggers the opening of the exit barrier 17, the exit of the vehicle being counted from the number of vehicles present on the site which is managed and regulated by the means of access control so as not to exceed a threshold number and avoid saturation of the site 1.

  Access to the site reserved for heavy trucks responsible for the collection of the site may also be provided with access control equipment 18 similar to the access equipment 16 reserved for users' light vehicles. Such equipment 18 makes it possible to control the arrival of the trucks in charge of the collection, to record the identification data of the drivers and to communicate these data to the control room. These data recorded by the central equipment allow to edit logs or readings indicating the data of place, date, time, and object of the collections for the managers of the site. Such surveys can also be useful to truckers. In this event, it can be expected that the system is equipped, at the level of the output barrier of heavy trucks for example, a printing device for editing collection records at the request of truckers.

  Thus, in general, the means of collection and management can, from the set of data collected on each site, publish reports or newspapers indicating, inter alia: the number of visitors, the source of voluntary deposits, the loading weights, - the filling rates of the skips, - the records of the collections made by the truckers, the operating states of the equipment.

  Such a system according to the invention advantageously makes it possible to optimally manage the use of the deposition capacities in a refuse collection, to dynamically manage the operations of collection of skips by the service providers, to follow the rotation of the skips. and their shipment to the waste recovery sectors.

  FIG. 5 schematically shows a network comprising several decommissioning stations 1.1, 1.2,..., 1.n, 1.n + 1, 1.n + 2,..., 1.n + p each equipped with the electronic system. according to the invention and connected to a common control R. The control room R comprises centralized data processing means sent to it by the system of each waste disposal site, these data relating to the loading weights of all the bins to the quantities of waste deposited by the various users as well as their identification.

  Such a network advantageously allows to manage several out of site waste, to track the loading and collection of all the bins of the network and the operations of the various users, even in the absence of guards.
