Description

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

Garbage from each household and business is put out at a designated collection point, such as by packing it in a garbage bag. Garbage discharged at each collection point is collected by a garbage truck and transported to a garbage incinerator. By properly grasping the number of garbage generated at each collection point, it can be applied in various ways, such as calculating the optimum garbage collection route by a garbage truck. For this reason, a modified garbage truck is also used in which a photoelectric sensor is mounted on a garbage truck and the photoelectric sensor measures the number of garbage thrown into the garbage truck at each collection point.

Since such a modified garbage truck needs to be modified according to the vehicle type of the garbage truck, it inevitably has a complicated configuration. For this reason, 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 based on the change in weight measured by the load cell. Has been proposed (see, for example, Patent Document 1).

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

Japanese Patent No. 3062118

By the way, in the work of actually collecting garbage, the worker is often busy because he is busy with time. The increase / decrease in weight measured by the load cell of Patent Document 1 due to this movement may be similar to the increase / decrease in weight due to the operator throwing the garbage into the garbage truck. In this case, in the invention of Patent Document 1, it is determined that the worker has thrown the garbage into the garbage truck even though the worker has not thrown the garbage into the garbage truck. Therefore, in the invention of Patent Document 1, a large error has occurred in the number of wastes to be measured.

Hereinafter, the waste number measuring device according to the embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 1, this garbage number measuring device is a device that measures the number of garbage G stored in the garbage truck T by the worker W. Here, the number of garbage G is the number of units of garbage that can be grasped (for example, a garbage bag or a lump of garbage).

The dust number measuring device 1 includes a grip detector 2 that detects a gripping motion of the garbage G by the worker W, and a lifting detector 3 that detects a lifting motion of the grasped garbage G. Further, the dust number measuring device 1 is based on the gripping operation of the dust G detected by the grip detector 2 and the lifting operation of the dust G detected by the lifting detector 3.

It has an analysis 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 the gripping operation of the dust G from the pressure measured by the pressure sensor. When the sensor is a myoelectric potential sensor, the analysis unit is a myoelectric potential analysis unit that detects the gripping motion 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 grasped garbage G, for example, a sensor that measures a value that fluctuates due to the lifting operation of the garbage G and a lifting of the garbage G from the measured value. It has an analysis unit that detects movement. Examples of this sensor are an acceleration sensor that measures the acceleration of the hand that grabbed the garbage G, an angular velocity sensor that measures the angular velocity of the hand that grabbed the garbage G, and a magnetic sensor that measures the position of the hand that grabbed the garbage G from geomagnetism. Examples thereof include an angle sensor that measures the angle of the hand that holds the dust G, and an altitude meter that measures the altitude of the hand that holds the dust G from fluctuations in pressure. When the sensor is an acceleration sensor, the analysis unit is an acceleration analysis unit that detects the lifting operation of the dust G from the acceleration measured by the acceleration sensor. When the sensor is an angular velocity sensor, the analysis unit is an angular velocity analysis unit that detects the lifting operation of the dust G from the angular velocity measured by the angular velocity sensor. When the sensor is a magnetic sensor, the analysis unit is a position analysis unit that detects the lifting operation of the dust G from the position measured by the magnetic sensor. When the sensor is an angle sensor, the analysis unit is an angle analysis unit that detects the lifting operation of the dust G from the angle measured by the angle sensor. When the sensor is an altimeter, the analysis unit is an altitude analysis unit that detects the lifting operation of the dust G from the altitude measured by the altimeter.

The collection determination unit 4 is generated by the worker W based on the gripping operation of the dust G detected by the grip detector 2 and the lifting operation of the dust G detected by the lifting detector 3. The operation of storing G in the garbage truck T is determined. Specifically, in determining the operation of storing the garbage G in the garbage truck T, the operation of grasping the garbage G and the operation of lifting the garbage G are processed as AND, so other than storing the garbage G in the garbage truck T. Do not mistakenly judge the operation.

Since the garbage number measuring unit 5 measures the number of operations for storing the garbage G in the garbage truck T by the worker W determined by the collection determination unit 4, the operation from the collection determination unit 4 It is also an adder that adds up the number of.

Of the configurations 2 to 5 of the dust number measuring device 1, only the sensors of the grip detector 2 and the lift detector 3 may be attached to the worker W. In other words, among the configurations 2 to 5 of the waste number measuring device 1, configurations other than the two sensors are provided in an office personal computer or the like away from the worker W, and information from both sensors is wirelessly provided. It may be received and processed.

Hereinafter, the operation of the waste number measuring device 1, that is, the method of using the waste number measuring device 1 will be described.

The worker W stops the garbage truck T at a place where the garbage G is accumulated, such as a garbage collection point, and puts the garbage truck T in a state where the garbage G can be stored. Then, the worker W grabs the accumulated garbage G (for example, a garbage G bag) one by one and throws it into the garbage truck T. Worker W may carefully put the garbage G in the garbage truck instead of throwing it into the garbage truck unless he / she is busy with time, but in any case, the worker W collects the garbage G. There is no change in putting it in the car T. Here, the operation of grabbing and throwing the garbage G is the operation of grabbing the garbage G, the operation of lifting the grasped garbage G, and the operation of releasing the garbage G when the angle and speed of this lifting operation are such that the garbage G is blown away. It consists of operation. In addition, the operations of grasping the garbage G and placing it carefully include the operation of grasping the garbage G, the operation of lifting the grasped garbage G, the operation of lowering the garbage G, and the operation of decelerating or stopping the garbage G and then releasing it. Consists of. Each operation of accommodating the garbage G in the collection vehicle T has an operation of grasping the garbage G and an operation of lifting the grasped garbage G.

In the operation of the worker W, the gripping motion of the dust G by the worker W is detected by the grip detector 2, and the lifting motion of the gripped dust G is detected by the lifting detector 3. After that, based on the gripping operation of the garbage G detected by the gripping detector 2 and the lifting operation of the garbage G detected by the lifting detector 3, the operation of putting the garbage G into the garbage truck T by the worker W is performed. , It is determined by the collection determination unit 4. Next, the number of operations for storing the garbage G in the garbage truck T by the worker W determined by the collection determination unit 4 is measured by the garbage number measuring unit 5.

As described above, according to the garbage number measuring device 1, the operation of storing the garbage G in the garbage collecting vehicle T by the worker W is determined based on the operation of grasping the garbage G and the operation of lifting the garbage G. It is possible to more accurately measure the number of actions of storing the garbage G in the garbage truck T.

Hereinafter, the waste number measuring device 1 according to the first embodiment, which more specifically shows the embodiment, will be described with reference to the drawings. In the first embodiment, the description will be focused on the configuration omitted in the embodiment, and the same configuration as the embodiment will be designated by the same reference numerals and the description thereof will be omitted.
"Garbage count measuring device 1"

First, the waste 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 dust number measuring device 1 includes a glove 10 fitted to a hand holding the dust G of the worker W and a mobile phone carried by the worker W in order to improve the convenience of the worker W. It is equipped with an information terminal 6 (smartphone, etc.). Since the gloves 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 waste 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 (finger tip ball) in the palm. The pressure sensor 20 constitutes a grip detector 2 together with the pressure analysis unit 21 of the center device 101, and the acceleration sensor 30 constitutes a lift detector 3 together with the acceleration analysis unit 31 of the center device 101. .. In order to transmit the pressure and acceleration information measured by the composite sensor 23 (pressure sensor 20 and acceleration sensor 30) from the glove 10, the dust number measuring device 1 is attached to the glove 10 and obtains the information. The glove transmitter 19 for transmitting is provided, and the code 11 for transmitting the information from the composite sensor 23 to the glove transmitter 19 is provided. For transmission of information from the glove transmitter 19, for example, a radio such as BLUETOOTH (registered trademark) is used.

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

The center device 101 calculates the number of operations of storing the garbage G in the garbage truck T based on the information of the receiving unit 131 that receives the information from the portable transmitting unit 69 and the receiving unit 131. A unit 140 is provided. The waste number calculation unit 140 includes the pressure analysis unit 21, the acceleration analysis unit 31, the collection determination unit 4, and the waste number measurement unit 5 described in the above embodiment.

The detection of the dust G gripping motion by the pressure analysis unit 21 and the detection of the dust G lifting motion by the acceleration analysis unit 31 will be described with reference to FIG. These detections are performed by the pressure analysis unit 21 and the acceleration analysis unit 31 of the center device 101, but in order to make the explanation based on the drawings easy to understand, FIG. 3 shows the display of the mobile information terminal 6 instead of the center device 101. Part 64 is shown.

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

As shown at the bottom of the display unit 64, the measured pressure may rise sharply 26 and then fall 28 sharply. When the measured pressure shows a sharp rise 26 and a subsequent sharp fall 28, the pressure analysis unit 21 considers that the worker W grabs the dust G and then releases it, and grips the dust G. Detects that there was.

As shown in the upper part of the display unit 64, the measured acceleration may increase to a predetermined value of 37 or more. When the measured acceleration increases by a predetermined value of 37 or more, the acceleration analysis unit 31 considers that the worker W has lifted the garbage G in order to put the garbage G in the garbage truck T, and the garbage G is considered to have been lifted. Detects that there was a lifting operation.

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 may also detect the operation of throwing the dust G. In this case, the analysis unit of the lifting detector 3 states that, for example, if the lifting operation has an angle and a speed sufficient to fly the dust G, it is considered that the dust G has been thrown in, and the dust G has been thrown in. Detect. In addition, the analysis unit of the lift detector 3 determines whether or not the information (acceleration, angular velocity and / or position, etc.) measured by the sensor of the lift detector 3 is equal to or higher than the threshold value, or by machine learning. , The operation of throwing the garbage G may be detected. Further, in addition to these, the information measured by the sensor of the lift detector 3 is made into a graph of time transition, and the operation of throwing dust G is detected based on the waveform pattern of this graph and / or the slope of this waveform. You may try to do it.

Of course, the detection of the dust G gripping motion by the pressure analysis unit 21 and the detection of the dust G lifting motion by the acceleration analysis unit 31 described with reference to FIG. 3 are merely examples, and are appropriately changed. You may. In addition to the graph described above, the display unit 64 may display position information 60 as shown in FIG.

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

As shown in FIG. 2, the worker W wears the glove 10 in his hand and carries the mobile information terminal 6. After that, the worker W stops the garbage truck T at the garbage collection point and puts the garbage truck T in a state where the garbage G can be stored. Then, the worker W grabs the garbage G (for example, the garbage G bag) at the garbage collection point one by one with the hand fitted with the glove 10 and throws it into the garbage truck T.

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

The pressure and acceleration information received by the portable receiving unit 61 is recorded in association with the position information 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 is transmitted from the mobile transmission unit 69 to the reception unit 131 of the center device 101.

In the center device 101, the information received by the receiving unit 131 is transmitted to the waste number calculation unit 140. Specifically, among the information received by the receiving unit 131, the pressure information is transmitted to the pressure analysis unit 21, and the acceleration information is transmitted to the acceleration analysis 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. do. Then, based on the detected operation of gripping the garbage G and the operation of lifting the garbage G, the operation of the worker W to put the garbage G in the garbage truck T is determined by the collection determination unit 4. Next, the number of operations for storing the garbage G in the garbage truck T by the worker W determined by the collection determination unit 4 is measured by the garbage number measuring unit 5.

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

That is, the grip detector 2 has the pressure sensor 20 and the pressure analysis unit 21, and the lift detector 3 has the acceleration sensor 30 and the acceleration analysis unit 31, so that the gripping operation of the dust G and the dust G can be performed more reliably. Lifting motion is detected. Therefore, it is possible to more accurately measure the number of operations for storing the garbage G in the garbage truck T.

Further, since the pressure sensor 20 measures the pressure at the base of the finger (fingertip ball) in the palm, the gripping motion of the dust G can be detected more reliably, so that the dust G can be more accurately collected by the garbage truck T. It is possible to measure the number of movements to be accommodated. In particular, the portion where the pressure is measured by the pressure sensor 20 is preferably the base portion of the index finger in the base portion (finger tip ball) of the finger. This is because the base of the index finger is a part where the pressure tends 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 motion of the dust G is detected more reliably, so the number of motions of storing the dust G in the garbage truck T more accurately. Can be measured.

Further, by forming the glove 10 with the composite sensor 23, the glove transmitter 19, and the cord 11, the number of objects to be worn by the operator 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 the measured pressure and acceleration information and is equipped with the GPS unit 63, it is possible to easily obtain the information on the position where the pressure and acceleration are measured. Can be done.

Hereinafter, the waste number measuring device 1 according to the second embodiment will be described with reference to the drawings. In the second embodiment, the arrangement of the acceleration sensor 30 in the waste number measuring device 1 according to the first embodiment is changed. In the second embodiment, the acceleration sensor 30 will be focused on, and the same configuration as that of the first embodiment will be designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 4, the dust number measuring device 1 according to the second embodiment includes an arm band 70 fitted to the arm on the side of the worker W who grips the dust G. The accelerometer 30 and an arm band transmitter 79 connected to the accelerometer 30 are attached to the arm band 70. The arm band transmitter 79 transmits the acceleration information measured by the acceleration sensor 30 from the arm band 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 a pressure sensor 20 instead of the composite sensor 23 as in the first embodiment. Further, since the information from the acceleration sensor 30 is transmitted by the arm band 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. The information of the pressure sensor 20 is transmitted instead of the transmission.

The reason why the accelerometer 30 is attached to the arm band 70 instead of the glove 10 is that the arm is easier to discriminate between the lifting motion of the dust G and the other motion than the hand. The arm band 70 is fitted to the forearm or upper arm of the worker W on the side that grips the dust G, but it is better to be fitted to the upper arm in order to more accurately discriminate between the lifting motion of the dust G and other motions. preferable.

As described above, according to the dust number measuring device 1 according to the second embodiment, since the acceleration sensor 30 is attached to the arm band 70 instead of the glove 10, the lifting operation of the dust G is detected more reliably. Therefore, it is possible to more accurately measure the number of operations for storing the garbage G in the garbage truck T.

Hereinafter, the waste number measuring device 1 according to the third embodiment will be described with reference to the drawings. In the third embodiment, the acceleration sensor 30 in the waste number measuring device 1 according to the second embodiment is changed to the angular velocity sensor 32. In the third embodiment, the configuration related to the angular velocity sensor 32 will be focused on, and the same configuration as that of the second embodiment will be designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 5, in the waste number 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 the angular velocity sensor 32. Correspondingly, the waste number calculation unit 140 in the waste number measuring device 1 according to the third embodiment has an angular velocity analysis unit 33 instead of the acceleration analysis unit 31 of the first and second embodiments.

The reason why the angular velocity sensor 32 is used instead of the acceleration sensor 30 is that the angular velocity makes it easier to determine the magnitude of the lifting operation of the dust G than the acceleration. Further, it is easier to distinguish between the lifting operation of the dust G and the other operations when the acceleration sensor 30 and the angular velocity sensor 32 are used in combination rather than using 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 waste number calculation unit 140 also has the function of the acceleration analysis unit 31.

As described above, according to the waste number 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 dust G can be lifted more reliably. Operation is detected. Therefore, it is possible to more accurately measure the number of operations for storing the garbage G in the garbage truck T.

The acceleration sensor 30 and the angular velocity sensor 32 of Examples 2 and 3 are not limited to being attached to the arm band 70, and 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 the geomagnetism may also be provided. This magnetic sensor is attached to a position corresponding to the wrist of the arm band 70 or 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 dust G lifting motion can be detected only by the magnetic sensor and the position analysis unit, the waste number measuring device 1 does not include the acceleration sensor 30, the angular velocity sensor 32, the acceleration analysis unit 31, and the angular velocity analysis unit 33 described above. You may.
"Garbage collection route optimization system 100"

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

The garbage collection route optimization system 100 has a plurality of garbage trucks T and mobile information terminals 6, and calculates the optimum garbage collection route by these garbage trucks T. The plurality of garbage trucks T are all garbage trucks T that are in charge of collecting garbage G in any area. The plurality of portable information terminals 6 are all the portable information terminals 6 of the worker W who stores the garbage G in the garbage truck T at the garbage collection point in the area.

The maximum load capacity of each waste collection vehicle T in charge of collecting waste G in an arbitrary area is checked in a catalog or the like, and is input to the maximum load capacity input unit 111 by, for example, a keyboard. On the other hand, when all the garbage trucks T have finished collecting the garbage G in the area, the total weight of the garbage G collected by each garbage truck T is input to the total garbage weight input unit 112 by, for example, a keyboard. do. The total weight of this garbage G is the total weight of each garbage truck T (containing the garbage G) measured at the garbage incineration facility, before the garbage G grasped in the catalog etc. is stored. It is calculated by reducing the total weight of each garbage truck T.

In the minimum number calculation unit 121 in the required number calculation unit 120, the minimum number is calculated by dividing the maximum load capacity of the garbage truck T from the total weight of the garbage G. The optimum number calculation unit 122 in the required number calculation unit 120 calculates the optimum route by correcting the minimum number of units by exchanging information from the optimum route calculation unit 160.

Information from the mobile transmission unit 69 of all the mobile information terminals 6 is transmitted to the waste number calculation unit 140 and the required time calculation unit 135 via the reception unit 131. The garbage number calculation unit 140 calculates the number of garbage G stored in the garbage collection vehicle T based on the information from the reception unit 131. In the unit weight calculation unit 132, the weight per waste G is calculated by dividing the number of waste G calculated by the waste G calculation unit from the total weight of the waste G input to the total waste weight input unit 112. Will be done. In the garbage number distribution calculation unit 133, the number of garbage G at each garbage collection point is calculated based on the position information from the garbage number calculation unit 140 and the information on the number of garbage G calculated by the garbage number calculation unit 140. It is calculated. In the garbage weight distribution calculation unit 134, the number of garbage G at each garbage collection point calculated by the garbage number distribution calculation unit 133 is multiplied by the weight per garbage G calculated by the unit weight calculation unit 132. The weight of garbage G at each collection point is calculated. The required time calculation unit 135 calculates the required time for each garbage truck T based on the information from the receiving unit 131.

The map acquisition unit 151 acquires a map (a map of the area) including all garbage collection points by downloading from the Internet or the like. The waste collection map creation unit 152 creates a waste collection map by adding the weight of the waste G for each waste collection point calculated by the waste weight distribution calculation unit 134 to this map. The optimum route calculation unit 160 tentatively calculates the optimum route for each garbage truck T from the required time and the garbage collection map. Further, in the optimum route calculation unit 160, a better optimum route is calculated by correcting the tentatively calculated optimum route by exchanging information with the optimum number calculation unit 122.

By displaying the garbage collection map and the optimum route as images on the monitor 170, it becomes easy for the worker W to grasp the new waste collection route (optimum route).

Is configured to be displayed on the display unit 64 and transmitted by the mobile transmission unit 69. With this configuration, the worker W can check the number of garbage G stored in the garbage truck T on the mobile information terminal 6 without returning to the office. In the waste collection route optimization system 100 with this configuration, since the center device 101 does not include the waste number calculation unit 140, the information of the reception unit 131 is directly transmitted to the unit weight calculation unit 132 and the waste number distribution calculation unit 133. Will be done.

Further, in FIGS. 2, 4, 5, and 7, an example in which one worker W is used is shown, but there may be a plurality of workers W.
