Description

  The present invention relates to a garbage number measurement device, a garbage number measurement system, and a garbage collection route optimization system including the same.

  Garbage from each home and business is discharged to a predetermined collection point by being packed in a garbage bag or the like. The garbage discharged at each collection point is collected by garbage trucks and transported to garbage incineration facilities. By properly grasping the number of garbage discharged at each collection point, various applications such as calculating an optimum garbage collection route by a garbage truck can be performed. Therefore, a modified garbage truck equipped with a photoelectric sensor mounted on the garbage truck and using the photoelectric sensor to measure the number of trash thrown into the garbage truck at each collection point is also used.

  Such a remodeled garbage truck needs to be remodeled according to the vehicle type of the garbage truck, and therefore has a complicated configuration. Therefore, instead of modifying the garbage truck, a load cell is attached to the sole of the worker who throws the garbage bag into the garbage truck at each collection point, and the number of garbage bags is determined by the change in the weight measured by the load cell. Has been proposed (for example, see Patent Document 1).

  According to the present invention, when the weight measured by the load cell suddenly decreases, it is determined that the worker has released his / her garbage, that is, the worker has thrown garbage into the garbage truck once. For example, at a certain collection point, if the sudden decrease in weight measured by the load cell is N times, it is determined that N pieces of garbage have been thrown into the garbage truck.

In this case, according to the invention of Patent Document 1, it is determined that the worker has thrown garbage into the garbage truck even though the worker has not thrown garbage into the garbage truck. Therefore, according to the invention of Patent Document 1, many errors occur in the number of garbage to be measured.

Further, the garbage number measuring device 1 includes a garbage number measuring unit 5 for measuring the number of operations for putting the garbage G determined by the collection determining unit 4 into the garbage collection vehicle T.

  Since the gripping detector 2 detects the gripping operation of the dust G, for example, a sensor that measures a value that fluctuates due to the gripping operation of the dust G, and detects the gripping operation of the dust G from the measured value. And an analyzing unit. Examples of this sensor include a pressure sensor that measures the pressure on the palm, a myoelectric potential sensor that measures the movement of the fingers of the hand, and the like. When the sensor is a pressure sensor, the analysis unit is a pressure analysis unit that detects a gripping operation of the dust G from the pressure measured by the pressure sensor. When the sensor is a myoelectric potential sensor, the analyzing section is a myoelectric potential analyzing section that detects a gripping operation of the dust G from the movement of the finger measured by the myoelectric potential sensor.

  Since the lifting detector 3 detects the lifting operation of the garbage G that has been grasped, for example, a sensor that measures a value that fluctuates due to the lifting operation of the garbage G, and the lifting of the garbage G from the measured value An analysis unit for detecting an operation.

This is to determine the operation of storing G in the garbage truck T. More specifically, the determination of the operation of storing the garbage G in the garbage collection vehicle T is performed by performing the AND operation on the garbage G gripping operation and the garbage G lifting operation. Do not judge the operation by mistake.

  Since the garbage number measuring unit 5 counts the number of operations for storing the garbage G in the garbage collection vehicle T by the worker W determined by the collection determining unit 4, the operation from the collection determining unit 4 is performed. It is also an adder that adds the number.

  Of the configurations 2 to 5 of the refuse number measuring device 1, only the sensors of the grip detector 2 and the lifting detector 3 may be mounted on the worker W. In other words, of the configurations 2 to 5 of the garbage number measuring device 1, the configurations other than the two sensors are provided in a personal computer or the like in an office remote from the worker W, and information from the two sensors is wirelessly transmitted.

  The worker W stops the garbage truck T at a place where the garbage G is accumulated, such as a garbage collection point, and places the garbage truck T in a state where the garbage G can be stored. Then, the worker W grabs the collected garbage G (for example, garbage G bag) one by one and throws it into the garbage collection vehicle T. The worker W may carefully place the garbage G in the collection truck instead of throwing the garbage G into the collection truck unless the time is over, but in any case, the garbage G is collected. There is no difference in putting it in the car T. Here, the operation of grabbing and throwing the garbage G is performed by the operation of gripping the garbage G, the operation of lifting the garbage G that has been grasped, and releasing the garbage G when the lifting operation is at an angle and speed enough to fly the garbage G.

  In the operation of the worker W, the grasping operation of the dust G by the worker W is detected by the grasp detector 2, and the lifting operation of the grasped dust G is detected by the lifting detector 3. Thereafter, based on the gripping operation of the garbage G detected by the grabbing detector 2 and the lifting operation of the garbage G detected by the lifting detector 3, an operation of storing the garbage G in the garbage collection vehicle T by the worker W is performed. Is determined by the collection determination unit 4. Next, the number of operations of putting the garbage G into the garbage collection vehicle T by the worker W determined by the collection determination unit 4 is measured by the garbage number measurement unit 5.

  As described above, according to the garbage count measuring device 1, the operation of storing the garbage G in the garbage collection vehicle T by the worker W is determined based on the gripping operation of the garbage G and the lifting operation of the garbage G. It is possible to more accurately measure the number of operations for placing the garbage G in the garbage truck T.

Hereinafter, a refuse number measuring apparatus 1 according to Example 1, which shows the embodiment more specifically, will be described with reference to the drawings. In the first embodiment, a description will be given focusing on the configuration omitted in the above-described embodiment, and the same components as those in the above-described embodiment will be denoted by the same reference numerals and description thereof will be omitted.
"Garbage counting device 1"

  First, a refuse number measuring device 1 according to the first embodiment will be described with reference to FIGS. 2 and 3.

  As shown in FIG. 2, the garbage count measuring device 1 includes a glove 10 that can be fitted to a hand of the worker W to grip the garbage G and a portable device that the worker W carries to improve the convenience of the worker W. An information terminal 6 (such as a smartphone) is provided. Since the glove 10 and the portable information terminal 6 are carried by the worker W, they are at the site where the garbage G is collected (see the left side of FIG. 2). On the other hand, the refuse number measuring device 1 also includes a center device 101 such as a personal computer installed in an office (see the right side of FIG. 2).

  A pressure sensor 20 and an acceleration sensor 30 are attached to the glove 10 as a composite sensor 23. The position where the composite sensor 23 is attached is a position where the pressure sensor 20 can measure the pressure at the base of the finger (the fingertip ball) on the palm. Note that the pressure sensor 20 constitutes the grip detector 2 together with the pressure analyzer 21 of the center device 101, and the acceleration sensor 30 constitutes the lifting detector 3 together with the acceleration analyzer 31 of the center device 101. . In order to transmit the information on the pressure and acceleration measured by the composite sensor 23 (the pressure sensor 20 and the acceleration sensor 30) from the glove 10, the garbage count measuring device 1 is attached to the glove 10 and transmits the information. The glove transmitter 19 is provided with a code 11 for transmitting the information from the composite sensor 23 to the glove transmitter 19. The transmission of the information from the glove transmitter 19 uses a radio such as BLUETOOTH (registered trademark).

  The portable information terminal 6 includes a portable receiving unit 61 that receives information from the glove transmitter 19, and a GPS unit 63 that detects a position where pressure and acceleration are measured by the composite sensor 23 (an example of a position detecting unit). And a recording unit 62 such as a memory. The recording unit 62 records the information received by the portable receiving unit 61 and the information of the position detected by the GPS unit 63 in association with each other. Further, the portable information terminal 6 includes a display unit 64 that displays information recorded by the recording unit 62, and a portable transmission unit 69 that transmits information recorded by the recording unit 62. Transmission of information from the portable transmission unit 69 is performed by wireless, such as LTE (registered trademark).

  The center device 101 includes a receiving unit 131 that receives information from the portable transmitting unit 69, and a garbage count calculation that calculates the number of operations that put the garbage G in the garbage collection vehicle T based on the information of the receiving unit 131. Unit 140. The garbage number calculating section 140 includes the pressure analyzing section 21, the acceleration analyzing section 31, the collection determining section 4, and the garbage number measuring section 5 described in the above embodiment.

  The detection of the gripping operation of the dust G by the pressure analysis unit 21 and the detection of the lifting operation of the dust G by the acceleration analysis unit 31 will be described with reference to FIG. Note that these detections are performed by the pressure analysis unit 21 and the acceleration analysis unit 31 of the center device 101. To make the explanation based on the drawings easy to understand, FIG. FIG.

  As shown in FIG. 3, a time variation 25 of the pressure measured by the pressure sensor 20 is displayed in a lower portion of the display unit 64 in a graph of time t (horizontal axis) -pressure P (vertical axis). On the other hand, a time variation 35 of the acceleration measured by the acceleration sensor 30 is displayed in a graph of time t (horizontal axis) -acceleration A (vertical axis) above the display unit 64.

  As shown at the bottom of the display 64, the measured pressure may rise abruptly 26 and then drop abruptly 28. When the measured pressure shows a sharp rise 26 and a sharp fall 28 thereafter, the pressure analysis unit 21 considers that the worker W has gripped the garbage G and then released it, and the gripping operation of the garbage G is performed. Is detected.

  As shown at the top of the display 64, the measured acceleration may rise above a predetermined value 37. When the measured acceleration shows a rise of a predetermined value 37 or more, the acceleration analysis section 31 considers that the worker W has lifted the garbage G to put the garbage G in the garbage truck T, and the garbage G Is detected as having been lifted.

  The analysis unit of the lifting detector 3 including the acceleration analysis unit 31 may not only detect the lifting operation of the dust G, but also detect the operation of throwing the dust G. In this case, the analysis unit of the lifting detector 3 determines that, for example, if the lifting operation is at an angle and a speed enough to fly the refuse G, the refuse G is considered to have been thrown and the trash G has been thrown. Detect. In addition, the analysis unit of the lifting detector 3 determines whether information (acceleration, angular velocity, and / or position, etc.) measured by the sensor of the lifting detector 3 is equal to or greater than a threshold, or by machine learning. Alternatively, an operation of throwing garbage G may be detected. Further, in addition to the above, the information measured by the sensor of the lifting detector 3 is graphed over time, and the operation of throwing in the dust G is detected based on the waveform pattern of the graph and / or the slope of the waveform. You may make it.

  The detection of the gripping operation of the dust G by the pressure analysis unit 21 and the detection of the lifting operation of the dust G by the acceleration analysis unit 31 described with reference to FIG. 3 are merely examples, and may be changed as appropriate. May be. The display unit 64 may display not only the above-described graph but also position information 60 as shown in FIG.

  Hereinafter, the operation of the refuse number measurement device 1 according to the present embodiment, that is, a method of using the refuse number measurement device 1 will be described.

  As shown in FIG. 2, the worker W keeps the glove 10 on his / her hand and carries the portable information terminal 6. Thereafter, the worker W stops the garbage truck T at the garbage collection point, and places the garbage truck T in a state where the garbage G can be stored. Then, the worker W throws the garbage G (for example, garbage G bag) at the garbage collection point into the garbage truck T by grasping the garbage G one by one with the hand fitted with the glove 10.

  In the operation of the worker W, the pressure on the palm on which the glove 10 is fitted is measured by the composite sensor 23, and the acceleration of the hand on which the glove 10 is fitted is measured. The information on the measured pressure and acceleration is transmitted from the composite sensor 23 to the glove transmitter 19 via the cord 11, and transmitted from the glove transmitter 19 to the portable receiver 61.

  The information on the pressure and the acceleration received by the portable receiving unit 61 is recorded in association with the information on the position detected by the GPS unit 63 by the recording unit 62. The information recorded by the recording unit 62 can be displayed on the display unit 64 and transmitted from the portable transmission unit 69 to the reception unit 131 of the center apparatus 101.

  In the center device 101, the information received by the receiving unit 131 is transmitted to the garbage count calculating unit 140. Specifically, of the information received by the receiving unit 131, information on pressure is transmitted to the pressure analyzing unit 21, and information on acceleration is transmitted to the acceleration analyzing unit 31. The pressure analysis unit 21 detects the gripping operation of the dust G based on the pressure information from the receiving unit 131, and the acceleration analysis unit 31 detects the lifting operation of the dust G based on the acceleration information from the receiving unit 131. I do. Then, based on the detected grabbing operation of the garbage G and the lifting operation of the garbage G, the operation of the worker W to put the garbage G into the garbage collection vehicle T is determined by the collection determining unit 4. Next, the number of operations of putting the garbage G into the garbage collection vehicle T by the worker W determined by the collection determination unit 4 is measured by the garbage number measurement unit 5.

  As described above, according to the garbage number measuring device 1 according to the present embodiment, the following effects are also exhibited in addition to the effects of the garbage number measuring device 1 according to the embodiment.

  That is, since the grip detector 2 has the pressure sensor 20 and the pressure analyzer 21 and the lifting detector 3 has the acceleration sensor 30 and the acceleration analyzer 31, the gripping operation of the garbage G and the garbage G Lifting motion is detected. Therefore, it is possible to more accurately measure the number of operations for putting the garbage G in the garbage truck T.

  Further, since the pressure sensor 20 measures the pressure at the base of the finger (the ball of the fingertip) of the palm, the gripping operation of the garbage G is detected more reliably. The number of actions to be accommodated can be measured. In particular, the portion where the pressure is measured by the pressure sensor 20 is preferably the base of the index finger of the base of the finger (the fingertip ball). This is because the base of the index finger is a portion where the pressure is likely to increase due to the gripping of the dust G. If the part where the pressure is measured by the pressure sensor 20 is the base of the index finger, the gripping operation of the garbage G is detected more reliably, and therefore the number of operations for more accurately putting the garbage G into the garbage collection vehicle T Can be measured.

  Furthermore, by using a configuration in which the composite sensor 23, the glove transmitter 19, and the cord 11 are attached to the glove 10, the number of objects worn by the worker W is reduced. Therefore, the burden on the worker W can be reduced.

  In addition, since the portable information terminal 6 carried by the worker W receives information on the measured pressure and acceleration and includes the GPS unit 63, it is easy to obtain information on the position where the pressure and acceleration are measured. Can be.

  Hereinafter, a refuse number measurement device 1 according to a second embodiment will be described with reference to the drawings. In the second embodiment, the arrangement of the acceleration sensor 30 in the garbage count measuring device 1 according to the first embodiment is changed. In the second embodiment, the description will focus on the acceleration sensor 30, and the same components as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  As shown in FIG. 4, the garbage count device 1 according to the second embodiment includes an arm band 70 that is fitted to the arm of the worker W on the side that grasps the garbage G. The acceleration sensor 30 and an arm band transmitter 79 connected to the acceleration sensor 30 are attached to the arm band 70. The wristband transmitter 79 transmits information on the acceleration measured by the acceleration sensor 30 from the wristband 70.

  Since the acceleration sensor 30 of the second embodiment is attached to the arm band 70, the sensor attached to the glove 10 is not the composite sensor 23 as in the first embodiment but the pressure sensor 20. Further, since the information from the acceleration sensor 30 is transmitted by the wristband transmitter 79, the glove transmitter 19 attached to the glove 10 transmits the information of the pressure sensor 20 and the acceleration sensor 30 as in the first embodiment. Instead of transmitting, the information of the pressure sensor 20 is transmitted.

  The reason why the acceleration sensor 30 is attached to the arm band 70 instead of the glove 10 is that it is easier for the arm to discriminate the lifting operation of the dust G and the other operation than for the hand. The arm band 70 is fitted to the forearm or the upper arm of the worker W on the side that grasps the garbage G. In order to more accurately determine the lifting operation of the garbage G and the other operation, it is preferable that the arm band 70 is fitted to the upper arm. preferable.

  As described above, according to the garbage count measuring apparatus 1 according to the second embodiment, the acceleration sensor 30 is attached to the arm band 70 instead of the glove 10, so that the lifting operation of the garbage G is detected more reliably. Therefore, the number of operations for putting the garbage G in the garbage truck T can be measured more accurately.

  Hereinafter, a refuse number measurement device 1 according to a third embodiment will be described with reference to the drawings. In the third embodiment, the acceleration sensor 30 in the garbage count measuring apparatus 1 according to the second embodiment is changed to an angular velocity sensor 32. In the third embodiment, the description will focus on the configuration related to the angular velocity sensor 32, and the same components as those in the second embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  As shown in FIG. 5, in the garbage count measuring device 1 according to the third embodiment, the sensor attached to the arm band 70 is not the acceleration sensor 30 of the second embodiment but an angular velocity sensor 32. Correspondingly, the garbage count calculating unit 140 in the garbage count measuring device 1 according to the third embodiment has an angular velocity analyzing unit 33 instead of the acceleration analyzing unit 31 of the first and second embodiments.

  The reason that the angular velocity sensor 32 is used instead of the acceleration sensor 30 is that the angular velocity is easier to determine the magnitude of the dust G lifting operation than the acceleration. In addition, when the acceleration sensor 30 and the angular velocity sensor 32 are used together, it is easier to discriminate the lifting operation of the dust G from the other operations than to use the angular velocity sensor 32 instead of the acceleration sensor 30. Therefore, the sensors attached to the arm band 70 may be the acceleration sensor 30 and the angular velocity sensor 32. In this case, the angular velocity analysis unit 33 of the garbage count calculation unit 140 also has the function of the acceleration analysis unit 31.

  As described above, according to the garbage count measuring device 1 according to the third embodiment, the angular velocity sensor 32 (or the acceleration sensor 30 and the angular velocity sensor 32) is attached to the arm band 70, so that the garbage G can be more reliably lifted. Movement is detected. Therefore, the number of operations for putting the garbage G in the garbage truck T can be measured more accurately.

The acceleration sensor 30 and the angular velocity sensor 32 of the second and third embodiments are not limited to being attached to the arm band 70 but may be attached to a position corresponding to the wrist of the glove 10. Further, in addition to the acceleration sensor 30 and / or the angular velocity sensor 32, a magnetic sensor that measures the position of the hand holding the dust G from geomagnetism may be provided. This magnetic sensor is attached to the arm band 70 or a position corresponding to the wrist of the glove 10. In this case, the acceleration analysis unit 31 / angular velocity analysis unit 33 of the waste number calculation unit 140 also has a function as a position analysis unit that detects the lifting operation of the waste G from the position measured by the magnetic sensor. If the lifting operation of the dust G can be detected only by the magnetic sensor and the position analyzing unit, the dust counting device 1 does not include the acceleration sensor 30, the angular velocity sensor 32, the acceleration analyzing unit 31, and the angular velocity analyzing unit 33 described above. You may.
"Waste collection route optimization system 100"

  Hereinafter, a garbage collection route optimization system 100 including the garbage number measuring device 1 according to the first to third embodiments will be described with reference to the drawings. In the refuse collection route optimizing system 100, the same components as those of the above-described refuse number measuring device 1 are denoted by the same reference numerals, and description thereof is omitted.

  The garbage collection route optimization system 100 includes a plurality of garbage collection vehicles T and portable information terminals 6, and calculates an optimum garbage collection route for the garbage collection vehicles T. The plurality of garbage collection vehicles T are all garbage collection vehicles T in charge of collecting garbage G in an arbitrary area.
