JP 2001-130706 A

However, in the past, for each of a huge number of stations, the collected waste was weighed, recorded in a book (station name, weighed weight, collected records, etc.), invoice slip creation, etc. Since the cleaning worker often performs the work manually and the work load is large, there is a possibility that a human error occurs in any of the work.
In addition, since the weight recording or the like largely depends on human work, there is a risk that fraudulent acts such as inflating may occur, and a preventive measure has been desired.

  The present invention has been made under the circumstances as described above, and in a garbage collection vehicle that collects waste by visiting a plurality of waste collection points, various operations after waste collection are automated and accurate. It is an object of the present invention to provide a garbage collection vehicle, an operation management system for a garbage collection vehicle, a center device, and an operation management method for a garbage collection vehicle capable of recording a simple collection history and preventing illegal acts.

In order to solve the above-mentioned problems, a garbage collection vehicle according to the present invention receives a radio wave from a GPS satellite in a garbage collection vehicle that circulates a plurality of waste collection sites in a predetermined area and collects waste. Vehicle positioning means for positioning the latitude / longitude of the vehicle, a non-volatile memory in which latitude / longitude information and names of collection points of all waste collection points in the predetermined area are recorded as a whole list, and names of a plurality of points From the list of display means capable of displaying the list, the vehicle position measuring means, the nonvolatile memory, the vehicle-mounted device for controlling the operation of the display means, and the waste collection place displayed on the display means, Selection means for specifying the current collection place name by selection judgment, and on-vehicle equipment side communication means for transmitting the collection place name specified by the selection means to the operation management center of the garbage truck via a data communication network Wherein the vehicle-mounted device, the positioning data of the vehicle latitude or longitude and positioning by the vehicle positioning means when the vehicle stops, on the basis of the total recorded listed in the nonvolatile memory, the distance from the vehicle extracting the waste collection site near a predetermined number from the whole list, characterized in that displayed on the display means in sorted distance from the host vehicle is closer.

According to such a configuration, the name of the collection place in each waste collection place need only be selected by the cleaning worker from the list displayed on the display means. In particular, the list of the collected collection places is the vehicle. Since they are sorted and displayed in ascending order of the distance from the operator, the worker can easily and reliably specify.
Therefore, the work after the waste collection of the cleaning worker accompanying the garbage truck is simplified and accurate by automation, and it is possible to prevent human errors such as erroneous entry of the name of the collection place.
In addition, the cleaning worker can select the collection site name from the displayed list, and can transmit the result to the operation management center.

In this way, various collection histories at each collection station can be recorded and held in the nonvolatile memory or the operation management center.

In addition, when there is no waste to be collected at the waste collection point according to an instruction from the weighing start unit, the on-vehicle device records a weight value of 0 as the measurement result in the nonvolatile memory and is within a communication range. It is desirable to transmit to the operation management center by the onboard equipment side communication means.
That is, when weighing is performed without collecting the waste in the vehicle, there is a possibility that the value of the weighing result may not become zero due to a change in the total weight of the waste accumulated so far over time. By forcing the value to 0, erroneous billing and the like can be prevented.

Moreover, it is desirable that the on-vehicle device further records information unique to the on-vehicle device and a data communication area identification flag in the non-volatile memory according to an instruction from the measurement start unit.
In this way, for example, by reading the data recorded in the nonvolatile memory in the operation management center, the vehicle-mounted device, that is, the garbage collection vehicle can be identified from the information unique to the vehicle-mounted device, and from the data communication area identification flag, It is possible to specify at which collection site data communication could not be performed.

Further, while the vehicle is running, the vehicle positioning means periodically measures the latitude and longitude of the vehicle position and outputs positioning data to the vehicle-mounted device, and the self-weight meter calculates the total weight of the loaded waste. The measurement result is output to the on-vehicle device, and the on-vehicle device outputs the position information based on the positioning data by the on-vehicle device side communication means when a predetermined amount of change occurs in the total weight of the loaded waste. It is desirable to transmit to the operation management center.

Collection history data is recorded in This collection history data includes date / time information, weighing result of collected waste, latitude / longitude data, station name, telephone number as information unique to the vehicle-mounted device, and a flag (data that identifies whether or not the data communication network N is within range) Communication range identification flag).
Note that the entire list is stored in a state of being sorted based on latitude or longitude.

  Among these, the telephone number of the vehicle-mounted device is used in the operation management center 1 to identify which vehicle-mounted device 11 (garbage truck 10) the collection history data to be managed is. That is, for example, when each of the plurality of CF cards 14 brought in from a plurality of garbage collection vehicles 10 identifies which on-board device 10 is, by referring to the telephone number data recorded therein Can be easily identified.

The data communication area identification flag indicates which station 20 communicates when the contents of the CF card 14 are read by the center device 1a of the operation management center 1 after the patrol of the predetermined area A by the garbage collection vehicle 10 is completed. Used to select whether the collection history has not been updated because communication is not possible outside the service area.
Further, the printer 15 is provided for printing the weight of the waste collected at each station 20 and the billing amount converted based on the weight and outputting it as a bill.

  Further, the vehicle rear portion 10b is provided with a dead weight 16 capable of measuring the weight of the waste collected at each station or the total weight of the waste accumulated so far. The self-weighing scale 16 has a display 16a for displaying a weighed weight value, and a weighing start button 16b (weighing start means) for instructing the start of weighing and the printing start by the printer 15.

  In addition, the weighing scale 16 is connected to the vehicle-mounted device 11, and when the weighing start button 16b is pressed, the weighing result is recorded on the CF card 14 as the collected history data together with the date / time information, station name, latitude / longitude data, etc. The information is transmitted to the operation management center 1 by the communication device 13. When the measurement result is recorded on the CF card 14, a telephone number and a data communication area identification flag as information unique to the vehicle-mounted device are simultaneously recorded as collection history data.

  That is, the cleaning worker collects the waste at each station 20 and presses the weighing start button 16b to start the weighing, and the weight of the waste as the weighing result, the billing amount based on the weight, and the like are printed by the printer 15. At the same time, collection history data including the weight of collected waste is recorded on the CF card 14 and transmitted to the operation management center 1 if data communication is possible.

  An operation panel 17 is provided at the vehicle rear portion 10b. The operation panel 17 is a display 17a (display means) for displaying names of a plurality of stations around the vehicle and a cleaning worker for selecting and specifying the current station from the displayed list of station names. It has an operation button 17b (selection means).

  The operation panel 17 is connected to the vehicle-mounted device 11, and the station name selected by operating the operation button 17 b is specified as the name of the station 20 currently performing the collection work and is output to the vehicle-mounted device 11. Therefore, the station name selected by the operator on the operation panel 17 is output to the printer 15, the CF card 14, and the operation management center 1 as the station name in the collection history data.

  Furthermore, the garbage collection vehicle 10 is provided with vehicle information output means 18, and vehicle information such as vehicle speed information, side brake information, and engine speed is input to the vehicle-mounted device 11 from the vehicle information output means 18. It is comprised so that. That is, the vehicle-mounted device 11 determines whether or not the vehicle has stopped based on the vehicle information from the vehicle information output means 18.

  Subsequently, in the operation management system 100 configured as described above, a process in which one garbage collection vehicle 10 circulates the predetermined area A and performs the waste collection work for all the stations 20 in the area is a flow of FIG. Based on

  First, when one garbage collection vehicle 10 starts patrol of the predetermined area A, the vehicle-mounted device 11 periodically performs GPS positioning with the GPS receiver 12 during traveling, and the obtained latitude / longitude of the vehicle is obtained. The positioning data is transmitted to the center device 1a of the operation management center 1 via the data communication network N (step S1 in FIG. 3). That is, in the operation management center 1, it is possible to always grasp where each garbage truck 10 is located.

  When the garbage collection vehicle 10 arrives at the first station 20 and stops (step S2 in FIG. 3), the vehicle-mounted device 11 determines that the vehicle is stopped based on the input information from the vehicle information output means 18, and the GPS receiver 12 receives the latitude.・ Implement longitude positioning processing. And the onboard equipment 11 calculates | requires final latitude and longitude based on the obtained positioning data (step S3 of FIG. 3). This GPS positioning process will be described later in detail.

  When the latitude / longitude of the host vehicle is obtained, the vehicle-mounted device 11 extracts a predetermined number of stations 20 (station name, latitude / longitude information) that are close to the host vehicle from the station list, and the distance from the host vehicle. The station candidate extraction process for sorting is performed according to (step S4 in FIG. 3). The station candidate extraction process will be described later in detail.

  When performing the station candidate extraction process, the vehicle-mounted device 11 displays a list of stations 20 obtained by the process on the display 17a of the operation panel 17 (step S5 in FIG. 3). That is, the name of the station 20 currently performing the collection work is displayed on the top as a candidate on the display 17a.

  Here, the cleaning worker of the garbage truck 10 determines whether the station 20 at the current position is the same as the name displayed on the top of the display 17a (step S6 in FIG. 3). If they are the same, they are specified by the operation button 17b. If they are different, they are selected from other candidates displayed on the display 17 and the station name is specified by the operation button 17b (step S7 in FIG. 3).

  When the station name is specified, the cleaning worker of the garbage truck 10 performs the waste collection work of the station 20. When all the waste is collected, the weight of waste collected at the station 20 is displayed on the display 16a by pressing the weighing start button 16b of the self-weight 16 (step S8 in FIG. 3).

  When there is no waste to be collected at the station 20, it is designated in the dead weight 16 that there is no collected material by a predetermined operation by the worker, and the measurement start button 16b is pressed. This forces the waste weight to a value of zero. That is, if the weighing start button 16b is pressed without collecting the waste in the vehicle, the weight value may not be zero as a result of weighing due to a change in the total weight of the waste accumulated so far over time. Yes, forcing this to a value of 0 can prevent erroneous billing and the like.

  Also, as soon as weighing is performed, the obtained waste weight data is sent to the vehicle-mounted device 11, and the vehicle-mounted device 11 sends the weight of the waste collected at the station 20 to the printer 15 based on the weight. The calculated charge amount is printed on a predetermined sheet. The predetermined paper output by the printer 15 is, for example, a bill slip to a customer belonging to the station 20.

Further, the vehicle-mounted device 11 determines whether or not the current station position is within the range of the data communication network N (step S9 in FIG. 3). If communication is possible, the vehicle-mounted device 11 communicates with the operation management center 1 via the data communication network N. Send collection history data.
And the center apparatus 1a of the operation management center 1 specifies the garbage collection vehicle 10 based on the telephone number of the onboard equipment 11 which transmitted data, and records the received collection history data (step S10 of FIG. 3). The collection history data includes date / time information, station name, latitude / longitude data, collected waste measurement results, and the like.

The vehicle-mounted device 11 records the collected history data on the CF card 14 (step S11 in FIG. 3). At that time, in addition to the collection history data transmitted to the operation management center 1, a telephone number and data communication area identification flag as information unique to the vehicle-mounted device are also recorded.
In step S9, if the data communication network N is outside the service area, the vehicle-mounted device 11 records the collected history data on the CF card 14 without transmitting it to the operation management center 1 (step S11 in FIG. 3). At this time, the data communication area identification flag is recorded in a state indicating out of service area.

  When the waste collection operation at one station 20 is completed in this way (step S12 in FIG. 3), the garbage truck 10 travels around all the stations 20 in the predetermined area A (step S13 in FIG. 3). ), Processing and work from step S1 are repeated.

While moving between the stations 20, the self-weighing scale regularly measures the total weight of the loaded waste, and if a predetermined amount of change occurs in the total weight, the latitude / longitude at that point The position information of the drop position based on the positioning data is transmitted to the operation management center 1. Thereby, for example, it is possible to grasp the fall of the waste while the vehicle is traveling, and it is possible to specify the location.
However, the GPS positioning data may include an error. For this reason, for example, when the vehicle speed is 10 km / h or less, the drop position may be specified using a plurality of positioning data near the time when the total weight changes. In this case, the drop position can be grasped more accurately.

  Next, the GPS positioning process performed in step S3 of FIG. 3, that is, the GPS positioning process executed when the garbage collection vehicle 10 is stopped will be described with reference to FIGS. FIG. 4 is a flow chart of GPS positioning processing executed when the vehicle is stopped, and FIG. 5 is a diagram for supplementarily explaining the flow of FIG.

First, when the garbage collection vehicle 10 arrives at the station 20 and stops, the vehicle-mounted device 11 measures the latitude and longitude continuously by n times (n is a positive integer) by the GPS receiver 12 (step of FIG. 4). S31). FIG. 5 (a) shows an example of latitude when n = 9, that is, the result of nine times of GPS positioning.
Next, the vehicle-mounted device 11 sorts the measured latitude and longitude according to the size (step S32 in FIG. 4). FIG. 5B shows an example in which the latitudes are sorted in ascending order.

Next, m (m is a positive integer) latitude / longitude are removed from the maximum and minimum values of latitude / longitude in the sorted latitude / longitude list (step S33 in FIG. 4). FIG. 5B shows a case where m = 1.
And the onboard equipment 11 employ | adopts an average value or a center value as a final positioning value from the latitude and longitude in the remaining list | wrist (step S34 of FIG. 4). In FIG. 5B, the center latitude is shown in the list.

  As described above, according to the GPS positioning process based on the flow of FIG. 4, m latitudes / longitudes are removed from the maximum and minimum values of the latitude / longitude measured n times. In such a case, the error can be removed, and more accurate positioning is possible.

  Note that the GPS positioning process performed in step S3 of FIG. 3 is not limited to the method shown in the flow of FIG. For example, the latitude / longitude positioning may be performed only once when the vehicle is stopped, and may be adopted as the final value, or may be performed according to another flow shown in FIG. 6 in order to perform more accurate positioning. Good.

Here, according to the flowchart of FIG. 6, the case where the GPS positioning process performed in step S3 of FIG. 3 is performed will be described with reference to the supplementary illustration of FIG.
First, when the garbage collection vehicle 10 arrives at the station 20 and stops, the vehicle-mounted device 11 measures the latitude and longitude continuously by n times (n is a positive integer) by the GPS receiver 12 (step of FIG. 6). ST31).

The vehicle-mounted device 11 sorts the measured latitude and longitude according to the size (step ST32 in FIG. 6). Note that FIG. 7A shows an example of latitude when n = 9, that is, when GPS positioning is performed nine times and sorted in ascending order of values.
Next, the vehicle-mounted device 11 obtains a Gaussian function (normal distribution) f (x) in which the average value Av is Equation 1 and the variance σ is Equation 2 (Step ST33 in FIG. 6).

  FIG. 7B shows an example of the value of f (x). Further, when obtaining this f (x), f (Av) is obtained by Equation 3.

Then, the values sorted in step ST32 are respectively weighted by f (x) (step ST34 in FIG. 6). FIG. 7C shows values weighted by a normal distribution.
The on-vehicle device 11 determines the sum of the weighted values as latitude or longitude (step ST35 in FIG. 6).

  As described above, according to the GPS positioning process based on the flow of FIG. 6, it is possible to uniquely weight n positioning results, and to perform more accurate positioning in consideration of the number of times of positioning and dispersion. it can. Further, by performing the processing of Expression 3, a 0.3% error deviating from 3σ of the Gaussian function f (x) can be absorbed by the median value f (Av), and the sum of weights is set to 1. Thus, a decrease in gain can be suppressed.

Next, the station candidate extraction process performed in step S4 of FIG. 3 will be described based on the flowchart of FIG.
First, the vehicle-mounted device 11 searches the station list (entire list) recorded on the CF card 14 for the latitude obtained by GPS positioning after the vehicle stops (step S41 in FIG. 8).

Then, only the stations 20 within ± predetermined degrees with respect to the positioning latitude are extracted, and an extraction list is created in the work memory (step S42 in FIG. 8).
Next, the vehicle-mounted device 11 calculates the distance from the own vehicle (garbage truck 10) for each station 20 in the extraction list (step S43 in FIG. 8).
The in-vehicle device 11 sorts the extracted list in ascending order of distance from each station 20 (step S44 in FIG. 8).

Further, the vehicle-mounted device 11 adds a selection item “not applicable” indicating that there is no corresponding station name in the extraction list, and completes the final extraction list (step S45 in FIG. 8). By adding the “N / A” selection item to the list as described above, if there is no candidate in the extraction list as the station name of the station 20 that performs the collection work, it is selected and specified as “N / A”. The maintenance of subsequent data management can be facilitated.
When the station candidate extraction process is thus completed, the vehicle-mounted device 11 displays an extraction list on the display 17a of the operation panel 17.

In this way, according to the flow of FIG. 8, only the stations that are close to the host vehicle are extracted from the entire list, sorted and displayed according to the distance from the host vehicle. In particular, the entire list is sorted and stored on the basis of latitude, and a station close to the latitude of the own vehicle is extracted and the distance is determined and specified.
This extraction process is performed for the following reason. That is, since the number of stations in the predetermined area A (the number of stations in the entire list) is enormous, performing the sort process on all of them increases the load on the vehicle-mounted device 11. Therefore, by storing the entire data as described above and performing this process, only the stations necessary for the station specifying work are extracted, and the sort process is performed on the extracted list of stations, so that the vehicle-mounted device 11 Can reduce the load.

  In addition, when a plurality of garbage collection vehicles 10 visit different stations 20 in the predetermined area A, the names of stations that other collection vehicles 10 visit may be reflected in the extraction list. There is no problem in identifying the station. Moreover, since the same CF card 14 in which the entire list of the stations 20 is recorded can be used for each garbage collection vehicle 10, it is convenient in terms of management.

As described above, according to the embodiment of the present invention, in the waste collection operation at the station 20, the weight of the collected waste and the station name are associated with each other, so Printing, writing to the CF card 14, and transmission to the operation management center 1 are automatically performed. In addition, the station name in each station 20 only needs to be selected by the cleaning worker from the list displayed on the display 17a, and in particular, the list of stations 20 is sorted and displayed in order of increasing distance from the vehicle. The worker can be identified easily and reliably.
Therefore, the work after the waste collection of the cleaning worker who accompanies the garbage truck 10 is simplified and accurate due to automation, and human errors such as incorrect entry of the station name and waste weight, water invoice requests, etc. It is possible to prevent fraud.

In the embodiment described above, the station 20 is specified on the garbage truck 10 side, but the processing may be performed on the operation management center 1 side.
In this case, as shown in the block diagram of FIG. 9, the center device 1a of the operation management center 1 has a display 1d capable of displaying a list of a plurality of station names in addition to the center side communication means 1b and recording means 1c. (Center-side display means) and an operation button 1f (center-side selection means) for selecting and specifying a station name from the list display, and a control means 1e for controlling the operation thereof.

In the recording unit 1c, all station information (station name (accumulation location name), latitude / longitude data, etc.) in the predetermined area A is recorded in advance as a station list (overall list).
In this embodiment, all the latitude / longitude data measured by the garbage truck 10 are transmitted to the center device 1a.

  In this configuration, the control means 1e performs a station candidate extraction process based on the positioning data transmitted to the center device 1a when the vehicle is stopped, as in the flow of FIG. Is displayed on the display 1d. The specific operation of the station 20 is performed by, for example, the operator of the operation management center 1 using the operation button 1f, and the specified station name is transmitted to the garbage collection vehicle 10 by the center side communication means 1b.

  In addition, the latitude and longitude when the vehicle is stopped is determined a predetermined number of times when the vehicle is stopped, and the positioning data is transmitted to the center device 1a, and the operation of the vehicle-mounted device 10 described based on these positioning data is shown in FIG. You may perform a GPS positioning process similarly to a flow.

  By specifying the station 20 on the operation management center 1 side in this way, the load on the vehicle-mounted device 10 is reduced, and when the processing on the vehicle side is impossible due to a failure or the like, the processing on the operation management center 1 side is performed. Can be supplemented.

  Further, the station 20 may be specified on both the garbage truck 10 side and the operation management center 1 side. In this case, the station name can be specified more accurately by comparing the results of both.

In the above embodiment, the positioning data used for the station candidate extraction process is only the latitude, but only the longitude may be used instead. That is, the entire data may be sorted and stored using longitude instead of latitude.
Further, although the CF card 14 has been described as an example of the nonvolatile memory, other media forms such as an SD card and a smart card may be used as long as the nonvolatile memory is used.
Moreover, although the telephone number of the onboard equipment has been described as an example as the information unique to the onboard equipment, for example, an individual onboard equipment such as a serial number may be specified.
In the GPS positioning process described based on the flow of FIGS. 4 and 6, positioning is performed continuously n times and n positioning data are acquired. However, positioning is performed by n GPS receivers 12. N positioning data may be acquired.

  The present invention can be suitably used in a waste collection business that collects business-related general waste generated in, for example, stores and companies.
