Description

The present invention relates to a wearable measuring device.

When harvesting headed leafy vegetables such as cabbage, the stems are usually cut, then the headed parts are sorted by size in the field and packed in boxes. When sorting the head parts by size, most producers do not use scales, but sort by sight and feel. For this reason, there is a possibility that the shipped product varies greatly, and the box may contain a head part that does not meet the standard described on the box or a head part that exceeds the standard.

In addition, for soft vegetables shipped in bags, the minimum weight per bag is fixed, so the prepared vegetables must be placed on a scale, weighed, and lifted again, which is not good workability.

On the other hand, Patent Literature 1 discloses a technique of obtaining weight information of agricultural products by providing a pressure sensing unit on the palm of the glove. In addition, Patent Documents 2 and 3 disclose techniques related to gloves capable of detecting finger operation force.

Therefore, it is difficult to hold the crop so as not to touch anything other than the pressure sensing unit, and if the crop touches anything other than the pressure sensing unit, the weight of the crop may be erroneously detected. In addition, the above-mentioned Patent Document 1 does not propose a usage method other than obtaining weight information.

<<1st Embodiment>>
The wearable measuring device according to the first embodiment will be described in detail below with reference to FIGS. 1 to 6. FIG.

FIG. 1 schematically shows the configuration of a wearable measuring device 100 according to the first embodiment. As shown in FIG. 1, the wearable measuring device 100 includes a left glove 10L, a right glove 10R as wearing tools, and a first control device 14L and a second control device 14R. Note that FIG. 1 shows the first control device 14L and the left glove 10L as separate bodies, and the second control device 14R and the right glove 10R as separate bodies. , the first control device 14L is provided integrally with the left glove 10L, and the second control device 14R is provided integrally with the right glove 10R.

The left glove 10L and the right glove 10R are gloves worn by a farm worker on both hands when performing farm work.

Variable resistors 12LA, 12LB, 12LC, 12LD, and 12LE are provided on the palm side of each fingertip of the left glove 10L (the pads of the fingertips). These variable resistors 12LA to 12LE are connected in series between the first terminal 28a and the second terminal 28b shown in FIG. The variable resistors 12LA-12LE change their resistance values according to the applied pressure. In the first embodiment, the variable resistors 12LA to 12LE function as pressure-sensitive sensors whose resistance values decrease as the acting pressure increases.

The first control device 14L has a circuit section 16L as a detector and a communication section 18L. The circuit section 16L has a power source 22 and an internal resistor 24 . The circuit section 16L includes the variable resistors 12LA to 12LE described above, and the variable resistors 12LA to 12LE and the internal resistor 24 are connected in series. The circuit section 16L also has a voltmeter 26L. The voltmeter 26L detects the voltage between the first terminal 28a and the second terminal 28b. The voltage value detected by the voltmeter 26L indicates a smaller value as the total resistance value of the variable resistors 12LA to 12LE decreases (the total force acting on the variable resistors 12LA to 12LE increases). .

The communication unit 18L acquires the voltage value detected by the voltmeter 26L at predetermined time intervals, and performs wireless communication (for example, Bluetooth (registered trademark), WiFi (registered trademark), near field communication (NFC: Near Field Communication), etc. ) to the second controller 14R.

Variable resistors 12RA, 12RB, 12RC, 12RD, and 12RE are provided on the palm side of each fingertip of the right glove 10R (the pads of the fingertips). These variable resistors 12RA to 12RE are connected in series between the first terminal 28c and the second terminal 28d shown in FIG. The variable resistors 12RA-12RE are the same as the variable resistors 12LA-12LE.

The second control device 14R has a circuit section 16R as a detector, a communication section 18R, an information processing section 30, a setting section 32 as a reception section, and an output section . The circuit section 16R has the same configuration as the circuit section 16L. A voltmeter 26R included in the circuit section 16R detects the voltage between the first terminal 28c and the second terminal 28d. The voltage value detected by the voltmeter 26R indicates a smaller value as the total resistance value of the variable resistors 12RA-12RE decreases (the total force acting on the variable resistors 12RA-12RE increases). .

The communication unit 18R receives information transmitted from the communication unit 18L of the first control device 14L by wireless communication.

The information processing section 30 acquires the voltage value detected by the voltmeter 26R and the information received by the communication section 18R (the voltage value detected by the voltmeter 26L) at predetermined time intervals. Based on the acquired information, the information processing section 30 then identifies information about the weight of the object (agricultural crops or articles used for agriculture) held by the farm worker. Here, the goods used for agriculture are, for example, pesticides and fertilizers. The weight information includes size information (S, M, L, etc.) in addition to the weight itself. Details of the information processing unit 30 will be described later.

The setting unit 32 receives an input from the farm worker and sets information about the weight specified by the information processing unit 30 . In the first embodiment, it is assumed that the farm worker can select one mode from the three modes of "weight", "cabbage", and "lettuce". When the farmer selects the mode "weight", the setting unit 32 sets the information processing unit 30 to specify the weight of the hand-held object such as crops, agricultural chemicals, and fertilizer. Further, when the farm worker selects the mode “cabbage” or “lettuce”, the setting unit 32 sets the information processing unit 30 to specify the size of the cabbage or lettuce held in the hand. Note that modes other than the above three modes may be included. For example, there may be a mode for specifying the size of crops other than cabbage and lettuce (pumpkins, radishes, etc.), a mode for specifying the amount (volume) of pesticides and fertilizers used (described later), and a mode for specifying the hardness of crops. There may be a mode to

The output unit 34 audio-outputs (notifies) the weight-related information specified by the information processing unit 30 through a speaker. For example, if the weight information specified by the information processing unit 30 is "700 g", the output unit 34 outputs a voice such as "It is 700 g". Further, if the weight information specified by the information processing unit 30 is “M size”, the output unit 34 outputs voice such as “M size”.

FIG. 5 shows the farmer holding an object (cabbage) as seen from below. In the first embodiment, as shown in FIG. 5, the farm worker puts the object to be weighed on the pad of each finger while wearing the left glove 10L and the right glove 10R. Do not touch objects other than the above).

The information processing section 30 will be described in detail below. FIG. 2 shows the hardware configuration of the information processing section 30. As shown in FIG. As shown in FIG. 2, the information processing unit 30 includes a CPU (Central Processing Unit) 90, a ROM (Read Only Memory) 92, a RAM (Random Access Memory) 94, a storage unit (such as an SSD (Solid State Drive)) 96, An input/output interface 97 and the like are provided. Each component of the information processing section 30 is connected to the bus 98 .

In the information processing section 30, the functions shown in FIG. 3 are implemented by the CPU 90 executing a program. Specifically, the information processing section 30 has functions as a voltage value acquisition section 60 , a force calculation section 64 , a weight calculation section 68 , and a setting reception section 72 .

The voltage value acquisition unit 60 acquires the voltage value (detection value of the voltmeter 26L) received by the communication unit 18R from the communication unit 18L of the first control device 14L and the detection value of the voltmeter 26R.

Force calculation unit 64 calculates the force applied to the left hand (that is, the weight of the article held by the left hand) based on the value detected by voltmeter 26L, and calculates the force applied to the right hand based on the value detected by voltmeter 26R. Compute the force exerted on (i.e. the weight of the article held by the right hand). Here, the force calculation unit 64 refers to the voltage-force table 40 and calculates the force applied to each hand. The voltage-force table 40 stores calibration curve information as shown in FIG. 4(a). The force calculation unit 64 calculates the force applied to the left hand corresponding to the detection value (voltage) of the voltmeter 26L from FIG. The force applied is calculated from FIG. 4(a).

The weight calculator 68 calculates information about the weight of the article held by the farm worker based on the calculation result of the force calculator 64 . Here, the setting reception unit 72 notifies the weight calculation unit 68 of the information of the mode selected by the farm worker, which is one of “weight”, “cabbage”, and “lettuce”, and the weight calculation unit 68 receives the selected mode. Calculation is performed according to the selected mode.

For example, when the mode "weight" is selected, the weight calculator 68 calculates the weight of the object held by the farm worker by summing the force applied to the left hand and the force applied to the right hand. do. When the mode "cabbage" is selected, the weight calculator 68 refers to the size table (for cabbage) shown in FIG. Determine the size of the cabbage corresponding to the weight of the cabbage). In addition, in the size table (for cabbage) of FIG. 4B, the correspondence between the weight and size of cabbage is defined. Similarly, when the mode "lettuce" is selected, the weight calculator 68 refers to the size table (for lettuce) as shown in FIG. Determine the size of lettuce corresponding to the weight of (lettuce). In addition, in the size table (for lettuce) of FIG. 4(c), the correspondence relationship between lettuce weight and size is defined. The calculation result of the weight calculation section 68 is notified to the output section 34 .

(Processing of information processing unit 30)
Next, the processing of the information processing section 30 will be described in detail along the flowchart of FIG. The process of FIG. 6 starts from the stage where the farmer puts on the left glove 10L and the right glove 10R, turns on the power, and selects one of the modes "weight", "cabbage", and "lettuce". shall be

In the process of FIG. 6, first, in step S10, the voltage value acquiring unit 60 acquires first and second voltage values. Here, the first voltage value is the voltage value detected by the voltmeter 26L of the left glove 10L, and the second voltage value is the voltage value detected by the voltmeter 26R of the right glove 10R. shall be

Next, in step S12, the voltage value acquiring unit 60 determines whether or not the amounts of variation from the initial values of the first and second voltage values are equal to or greater than a threshold. In this step S12, it can be said that it is determined whether or not the farmer has touched or held an object. A farmer performs normal farm work while wearing the gloves 10L and 10R. The hand shall be kept still for a predetermined time or longer. If the determination in step S12 is negative, the voltage value acquiring unit 60 returns to step S10, but if the determination is positive, the process proceeds to step S14.

After proceeding to step S14, the voltage value acquiring unit 60 determines whether or not the first and second voltage values have stabilized for a predetermined time or longer. That is, the voltage value acquisition unit 60 determines whether or not the hand holding the object has been stopped in order to obtain information on the weight of the object held by the farm worker. If the determination in step S14 is negative, the voltage value acquiring unit 60 returns to step S10, but if the determination is positive, the process proceeds to step S16. It is assumed that the voltage value acquisition unit 60 has delivered the first and second voltage values to the force calculation unit 64 when proceeding to step S<b>16 .

After moving to step S16, the force calculation unit 64 converts the first and second voltage values into a first force and a second force. Based on the voltage-force table 40 (calibration curve in FIG. 4(a)), the force calculation unit 64 calculates the first force (the weight applied to the left hand) corresponding to the first voltage value and the second voltage value A second force (the weight on the right hand) corresponding to .

Next, in step S18, the weight calculator 68 calculates weight from the first and second forces. The weight calculator 68 sums the first force and the second force to calculate the weight of both hands (that is, the weight of the object held by the farm worker).

Next, in step S20, the weight calculator 68 determines whether or not the mode selected by the farm worker is "weight". If the determination in step S20 is affirmative, the weight calculation unit 68 proceeds to step S22, but if the determination is negative, it proceeds to step S24.

When the determination in step S20 is affirmative and the process proceeds to step S22, the weight calculation unit 68 sets the weight calculated in step S18 as the weight information. For example, if the weight is calculated as "600 g" in step S18, the weight information is set to "600 g". After that, the process proceeds to step S30.

After step S22, when the process proceeds to step S30, the weight calculation section 68 notifies the output section 34 of FIG. 1 of the weight (600 g) as weight information. In this case, the output unit 34 outputs the voice "It's 600g" from the speaker. After that, the process returns to step S10.

On the other hand, when the determination in step S20 is negative and the process proceeds to step S24, the weight calculator 68 determines whether or not the mode selected by the farm worker is "cabbage". If the determination in step S24 is affirmative, the weight calculator 68 proceeds to step S26, but if the determination is negative, it proceeds to step S28.

In step S26, the weight calculation unit 68 obtains the size of the cabbage held by the farm worker from the calculated weight and the size table (for cabbage) shown in FIG. and

On the other hand, in step S28, the weight calculator 68 obtains the size from the calculated weight and the size table (for lettuce) shown in FIG. 4(c), and uses the obtained size as weight information.

After step S26 or step S28, the process proceeds to step S30. For example, if the weight information is "M size" as a result of step S26 or step S28, the weight calculation unit 68 outputs "M size" as the weight information to the output unit 34 in step S30. to notify you. In this case, the output unit 34 outputs a voice saying "It's an M size" from the speaker. After that, the process returns to step S10.

After that, the above-described processing of FIG. 6 is repeatedly executed until the farm worker inputs an instruction to finish the work (for example, turns off the power).

As described in detail above, the wearable measuring device 100 of the first embodiment includes a plurality of variable resistors 12LA to 12LE and 12RA to 12RE at a plurality of locations on the palm side of the gloves 10L and 10R. Voltmeters 26L and 26R included in circuit units 16L and 16R including variable resistors detect voltages corresponding to pressures acting on the variable resistors. Then, the information processing section 30 identifies information about the weight of the object held by the farmer based on the detection results of the voltmeters 26L and 26R, and the output section 34 outputs the identified information. Thus, in the first embodiment, when the farm worker holds the object, it is possible to notify the farm worker of information about the weight of the object (such as the weight and size of the object) by voice. Therefore, compared with the case where the farm worker judges the size by sight or feeling, it is possible to specify the information on the weight of the crop with high accuracy and inform the farm worker. In addition, when harvesting and packing the crops, the farm workers need to put the harvested crops on a scale to check the weight and size, lift the crops again from the scale, and put them in a box suitable for the weight and size. There is no In other words, the farmer can check the weight and size of the harvested crop by simply holding it with the hand wearing the gloves 10L and 10R, which simplifies the operation of putting the harvested crop into a box. can do. In addition, in the first embodiment, since a plurality of variable resistors are provided in each of the gloves 10L and 10R, it is possible to reduce the possibility that the crops will come into contact with other than the variable resistors when holding the crops. can. This makes it possible to specify the weight and size of agricultural products with high accuracy.

Also, in the first embodiment, a plurality of variable resistors 12LA to 12LE (12RA to 12RE) are provided at a plurality of locations on the palm side of the glove 10L (10R). In addition, the voltmeter 26L (26R) measures the change in voltage value between the first terminal 28a (28c) and the second terminal 28b (28d) to which a plurality of variable resistors 12LA to 12LE (12RA to 12RE) are connected in series. (ie change in resistance). Thereby, the weight applied to each hand can be detected by a simple calculation from the voltage value between the first terminal 28a (28c) and the second terminal 28b (28d).

In addition, in the first embodiment, the variable resistors 12LA to 12LE and 12RA to 12RE are provided in the palm side portions of the gloves 10L and 10R. ) is provided at a location facing the As a result, since the variable resistors 12LA to 12LE and 12RA to 12RE are provided at locations where there is a high possibility of contact with the object when the object is held, information regarding the weight of the object can be appropriately measured and output. can be done.

In addition, in the first embodiment, the setting unit 32 accepts input of information about weight specified by the information processing unit 30 and sets the weight. You can output information about the weight you want.

In addition, in the first embodiment, in the case of crops such as vine vegetables (for example, watermelons and melons), the crops are held (with the crops attached to the vines) before harvesting, and the weight of the crops is increased. Information can be identified. As a result, the farmer can harvest the crops after knowing the information about the weight of the crops, and thus can be prevented from erroneously harvesting non-standard crops.

In the above-described first embodiment, the case where the output unit 34 audio-outputs the weight-related information via the speaker has been described. You can do it. In this case, a display device such as an organic EL display may be provided on the right glove 10R.

In the first embodiment, the case where the first control device 30L is provided on the left glove 10L and the second control device 30R is provided on the right glove 10R has been described, but the present invention is not limited to this. For example, the first controller 30L may be provided on the right glove 10R and the second controller 30R may be provided on the left glove 10L. In addition, both the gloves 10L and 10R are provided with the first control device 30L, and the first voltage value and the second voltage value are transmitted to an external device (for example, an information processing terminal such as a smartphone) by wireless communication (such as Bluetooth (registered trademark)). ) may be transmitted. In this case, the processing of FIG. 6 may be executed in the external device, and the weight information may be output as voice from the speaker of the external device or displayed on the display device of the external device.

In the first embodiment, the detection results (voltage values) of the voltmeters 26L and 26R are used to specify the weight information, but the present invention is not limited to this. For example, ammeters may be provided to measure currents flowing through the circuit units 16L and 16R, and weight information may be specified based on the current values.

In addition, in the first embodiment, the case where one variable resistor is provided for each finger of the gloves 10L and 10R has been described, but the present invention is not limited to this. For example, as shown in FIG. 7, variable resistors 12LA', 12LB', 12LC', 12LD', and 12LE' may be added in association with each finger to provide two variable resistors for each finger. . Also, the arrangement and number of variable resistors can be appropriately changed in consideration of the position of the hand that is likely to come into contact with the object when holding the object.

In the above-described first embodiment, the case where the object held by the farmer is a crop such as cabbage has been described as an example, but the object is not limited to this, and may be an agricultural chemical or fertilizer, for example. In this case, the information processing section 30, for example, first measures and stores the weight of the bottle containing the pesticide or fertilizer. Then, when the weight of the bottle is measured again after using the pesticide or fertilizer, the information processing section 30 outputs the value obtained by subtracting the measured weight from the first measured weight (the weight of the pesticide or fertilizer used). . This allows the farmer to check the amounts of pesticides and fertilizers used. Note that if the pesticide or fertilizer is liquid, the information processing section 30 may calculate the volume of the liquid from the weight of the liquid used and output information on the calculated volume. The information processing unit 30 may also output information based on changes in the weight of the bottle while the agricultural worker transfers the pesticide or fertilizer from the bottle to another container (such as raindrops). For example, when the amount transferred from the bottle to another container reaches a predetermined amount based on the change in the weight of the bottle, the farm worker may be notified.

Note that the wearable measuring device 100 of the first embodiment can also be used to detect the hardness of agricultural products. In this case, the farmer sets the mode to "Hardness". Then, the farm worker pushes the surface of the crop by a predetermined amount (eg, 5 mm) with one or more predetermined fingers (eg, the predetermined index finger shown in FIG. 8). At this time, the farm worker should not touch the crops with anything other than a predetermined finger.

In this case, the information processing section 30 obtains the voltage value when the crop is pressed, and obtains the pressing force based on the voltage value. Then, the information processing unit 30 refers to a table (force-hardness table) that defines the relationship between the pressing force and the hardness of the crop, and specifies the hardness corresponding to the pressing force. As a result, the output unit 34 outputs the information on the hardness of the crops by voice, so that the farm worker can confirm the correct hardness (maturity) of the crops. Therefore, the farm worker can appropriately determine the harvest time based on the hardness of the crop. Note that if the predetermined fingers are a plurality of fingers (for example, the index finger and the middle finger), the information processing unit 30 divides the pressing force obtained from the voltage value by the number of fingers (average value) to determine the hardness of the crop based on the force-hardness table.

<<Second embodiment>>
Next, a second embodiment will be described in detail with reference to FIGS. 9 and 10. FIG. In the second embodiment, the variable resistors placed on the thumb and the variable resistors placed on the other fingers are connected to different circuits.

FIG. 9 shows a wearable measuring device 200 according to the second embodiment. As shown in FIG. 9, in the second embodiment, the arrangement of variable resistors 12LA to 12LE and 12RA to 12RE in left glove 10L and right glove 10R is the same as in the first embodiment. However, the variable resistor 12LA and the variable resistors 12LB to 12LE are included in separate circuit sections 16L1 and 16L2, and the variable resistor 12RA and the variable resistors 12RB to 12RE are included in separate circuit sections 16R1 and 16R2. The point is different from the first embodiment. In FIG. 9, the voltage across the variable resistor 12LA is detected by the voltmeter 26L1, and the voltage across the variable resistors 12LB to 12LE is detected by the voltmeter 26L2. A voltage across the variable resistor 12RA is detected by a voltmeter 26R1, and a voltage across the variable resistors 12RB to 12RE is detected by a voltmeter 26R2. The voltage values detected by the voltmeters 26L1 and 26L2 are transmitted from the communication section 18L to the communication section 18R of the second control device 14R and input to the information processing section 30 . Also, the voltages detected by the voltmeters 26R1 and 26R2 are input to the information processing section 30. FIG.

The information processing unit 30 identifies information about the weight based on the detected values of the voltmeters 26L1, 26L2, 26R1, and 26R2, and the output unit 34 outputs the identified information about the weight by voice.

In addition, in the second embodiment, a farm worker can also measure the weight and size of a farm product by holding the farm product in the same manner as in the first embodiment (FIG. 5). In this case, the information processing unit 30 obtains the force (weight) from the detection values of the voltmeters 26L1, 26L2, 26R1, and 26R2, adds up the obtained weights, and calculates the weight of the crop and the size corresponding to the weight. can be specified.

In addition, in the second embodiment, it is also possible to measure the weight of the agricultural product when the agricultural product is gripped according to the inputs of the agricultural worker. The processing of the information processing unit 30 when the mode related to the method of specifying the weight of the crop is set to "grasping" will be described below.

FIG. 10 shows a farmer holding a pumpkin with his right hand. In this case, the farmer supports the pumpkin from below with his index finger, middle finger, ring finger, and little finger, and presses the pumpkin from above with his thumb. Here, the downward force applied from the thumb to the pumpkin is F1, and the downward forces applied from the pumpkin to the index, middle, ring and little fingers are F2, F3, F4 and F5.

In such a case, in step S16 of FIG. 6, the force calculation unit 64 of the information processing unit 30 determines the total force (F2+F3+F4+F5) applied to the index finger, middle finger, ring finger, and little finger as the measured value of the voltmeter 26R2. , from the voltage-force table 40 of FIG. 4(a). The force calculation unit 64 also obtains the force (F1) applied by the thumb to the pumpkin from the measured value of the voltmeter 26R1 and the voltage-force table 40 of FIG. 4(a). Then, in step S18 of FIG. 6, the weight calculator 68 subtracts F1 from the obtained (F2+F3+F4+F5) to calculate the weight F of the pumpkin held by the farmer (=F2+F3+F4+F5-F1).

When weighing the pumpkin, if it is predetermined that the farmer will hold the pumpkin with both hands, the weight applied to the right hand side is calculated as described above, and the weight applied to the left hand side is calculated as described above. is calculated in the same manner as for the right hand side, and the calculated weights are summed up.

Note that the weight calculation unit 68 may specify and output the size of the pumpkin from the weight of the pumpkin calculated as described above. In this case, the size of the pumpkin may be specified using a size table similar to the size tables shown in FIGS. 4B and 4C described in the first embodiment.

As described above, according to the second embodiment, the information processing unit 30 supports the crops from the upper side from the force acting on the fingers (index finger, middle finger, ring finger, little finger) that support the crops from the lower side. Determine the weight of the crop by subtracting the force exerted on the finger (thumb) that is applied. As a result, even when the farm worker holds the crop in the state shown in FIG. 10, it is possible to output the information regarding the weight of the crop with high accuracy.

In the above-described second embodiment, the thumb may be used to support the crop from below, and the fingers other than the thumb may be placed on the top of the crop. In such a case, the absolute value of the value obtained by subtracting F1 from (F2+F3+F4+F5) (F2+F3+F4+F5-F1) may be taken as the weight of the crop.

In addition, in the second embodiment, for example, leafy vegetables such as spinach are held with one hand (for example, the right hand) to measure the weight, and if the weight is predetermined, the leafy vegetables are placed in one bag. It can also be used when carrying out work of packing and shipping. In this case, if the leafy vegetables grasped with the right hand do not meet the specified weight, the farmer can know the weight of the shortage. Therefore, the farmer newly grasps the leafy vegetables to be added with the left hand and checks the weight of the whole leafy vegetables grasped with both hands, thereby adjusting the weight of the leafy vegetables to be packed in one bag. can do. For example, assume that the default weight to be packed in one bag is 300g. In this case, the farmer grasps the leafy vegetable with his right hand and checks the weight. As a result of this confirmation, if the weight is 280 g, grasp a small amount of leafy vegetables with the left hand and confirm whether the total weight is about 300 g. Then, when it is confirmed that the total weight has reached about 300 g, the farm worker may carry out the work of putting together the leafy vegetables grasped with the right hand and the left hand into one bag. In the second embodiment, the information processing unit 30 can separately measure the weight of the right hand and the left hand, so that the weight of the leafy vegetables grasped by each hand is output and notified to the farm worker. You may do so.

In the second embodiment, the arrangement and number of variable resistors may be as shown in FIG. 7, as in the first embodiment, or other arrangements and numbers may be adopted. Also, the output unit 34 may output the weight-related information by a method other than voice. In addition, the voltmeters of the circuit units 16L1, 16L2, 16R1, and 16R2 in FIG. 9 are replaced with ammeters, and based on the measurement results (current values) of the ammeters, information about the weight of the object held by the farmer is specified. It is also possible to

In the above-described first and second embodiments, the cases where the variable resistors are provided in the gloves 10R and 10L have been described, but the present invention is not limited to this. For example, as shown in FIG. 11, finger sacks 110R1, 110R2, 110R3, 110R4, and 110R5 that can be worn on fingers may each be provided with one or more variable resistors. By doing so, the hand can be easily moved, and workability can be improved. Also, it is possible to prevent the palm from getting stuffy. In addition, the farm worker only needs to wear finger cots on the fingers necessary for measuring weight and hardness.

In addition, in the first and second embodiments, the case where the weight and size of the farm product held by the farm worker is output by voice or the like to notify the farm worker has been described, but it is not limited to this. For example, when a farm worker packs crops into one box, the farm worker inputs "start packing". Then, the information processing section 30 may calculate the total value of the weights measured after "start packing" is input, and output the total value from the output section 34 by voice or the like. As a result, the farmer can know the total weight of the agricultural products contained in one box, so for example, when the agricultural products contained in the box can be shipped if the weight exceeds the specified amount, such as Chinese cabbage for processing Since it is no longer necessary to carry around a scale for measuring the weight of the box in the field at the time of harvesting, convenience can be improved.

In the above-described first and second embodiments, the case where the wearable measuring devices 100 and 200 output information about weight by voice or the like has been described. , the weight information may be output to an external device (cloud server, etc.). In the external device, for example, by accumulating information about the weight of crops for each field or for each row in the field, it can be used for data analysis about the growth status of crops. As a result, for example, by creating a yield map of crops in the field, it is possible to grasp the variation in yield in the field, and based on this, it is possible to make a fertilizer application plan.

The embodiments described above are examples of preferred implementations of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.
