Description

  The present invention relates to a management device and the like.

  As a countermeasure against birds and beasts, traps have been set up in forests, grasslands, and agricultural lands to capture birds and beasts that cause damage. Basically, the installation location of the trap is installed in a place where people do not approach very often, so in the related art, it is detected whether or not birds and beasts are captured in the trap by a detection function using a sensor, The user terminal is automatically notified by using the wireless communication function.

  FIG. 15 is a diagram for explaining an example of the related art. As shown in FIG. 15, this system has box traps 10a, 10b, 10c and a relay station 20. In the following description, the box traps 10a to 10c are collectively described as a box trap 10. Here, the description is made using the box trap 10, but other traps such as a hollow trap may be used.

  In the related art, in order to reduce equipment costs, a data communication is performed via the relay station 20 using a communication device for short-range communication that does not assume long-range communication as a wireless communication function of the box trap 10. Further, a battery having a small capacity for supplying power to the wireless communication function and the detection function of the box trap 10 is used. When the remaining amount of the battery becomes low, the user goes to the place where the box trap 10 is installed and replaces the battery. It is desirable that the wireless communication device be small in order to reduce the vigilance of wild animals (birds and beasts to be captured) and to reduce installation costs. Therefore, a device with a small battery capacity is generally used.

  The box trap 10 starts and stops based on preset schedule information in order to save the power consumption of the battery, and performs data communication with the relay station 20 during startup to detect the detection status and the like. Has been notified. Basically, the box trap 10 repeatedly starts and stops based on the schedule information. For example, the box trap 10 continues to operate the detection function from the battery even when the box trap 10 is stopped. When it is detected that birds and beasts have been captured, the wireless communication function is automatically started, and data communication with the relay station 20 is started.

  However, the conventional technique described above has a problem that the efficiency of the battery replacement operation is low.

  In the prior art, each box trap 10 repeatedly starts and stops based on predetermined schedule information, but each time a bird or beast is caught during the stop, data communication with the relay station 20 occurs individually. Therefore, the battery replacement time of each box trap 10 may be different. For this reason, the battery may be changed at different times for the box trap 10 installed nearby, which is inefficient.

  In one aspect, an object of the present invention is to provide a management device and a control method that can improve the efficiency of battery replacement work.

  In the first plan, the management device has a receiving unit, a generating unit, and an activation control unit. The receiving unit repeats start and stop based on the first schedule information, and executes data communication with a plurality of wireless communication devices that notify when detecting that birds and beasts are captured in the trap, and Information on the remaining battery level of the wireless communication device is received from the wireless communication device. The generation unit generates, for each wireless communication device, second schedule information in which the activation frequency is adjusted such that the difference between the remaining battery amounts of the plurality of wireless communication devices is less than the threshold. The activation control unit updates the first schedule information to the second schedule information by notifying the second schedule information to the wireless communication device, and controls the start and stop of the wireless communication device.

  The efficiency of battery replacement can be improved.

  Hereinafter, embodiments of a management device and a control method disclosed in the present application will be described in detail with reference to the drawings. The present invention is not limited by the embodiment.

  FIG. 1 is a diagram illustrating an example of a system according to the embodiment. As shown in FIG. 1, this system includes box traps 50a, 50b, 50c, 50d, 50e, 50f, and a relay station 100. Here, the box traps 50a to 50b are shown, but the system of the present embodiment may include other box traps. In the following description, the box traps 50a to 50f are collectively referred to as a box trap 50 as appropriate. Although the box trap 50 is used as an example of the trap here, another trap such as a hollow trap may be used.

  The box trap 50 is connected to the relay station 100 by short-range wireless communication such as Wi-Fi. Although not shown, the relay station 100 is connected to an external device by long-distance wireless communication such as LTE (Long Term Evolution) / 3G (Generation).

  The box traps 50 are grouped according to the attribute information of the box trap 50. The attribute information is information corresponding to the installation position of the box trap 50 or the installation difficulty when the box trap 50 is installed. In the present embodiment, as an example, it is assumed that box traps 50 having similar attribute information belong to the same group. In the example shown in FIG. 1, the box traps 50a, 50b, and 50c belong to the group 15a, and the box traps 50d, 50e, and 50f belong to the group 15b.

  The box trap 50 is a trap installed on a mountain forest, a cliff, a grassland, a farmland, or the like to capture birds and beasts. FIG. 2 is a diagram illustrating an example of the appearance of the box trap. Here, the box trap 50a will be described as an example. The description regarding the box traps 50b to 50f is the same as the description regarding the box trap 50a.

  As shown in FIG. 2, the box trap 50a includes a detection function unit 60 and a wireless communication function unit 70. The detection function unit 60 and the wireless communication function unit 70 are supplied with power from a battery. The detection function unit 60 always receives power supply from a battery. The wireless communication function unit 70 receives power supply from the battery only during the activation period.

  The detection function unit 60 has an acceleration sensor, and captures the bird and animal 6 by closing the door 5 when detecting that the bird and animal 6 has entered the inside of the box trap 50a. Further, when detecting that the bird and the animal have been captured, the detection function unit 60 transmits capture information indicating that the bird and the animal has been captured to the relay station 100 using the wireless communication function unit 70.

  The wireless communication function unit 70 executes short-range wireless communication with the relay station 100 during the activation. The wireless communication function unit 70 repeatedly starts and stops based on schedule information that defines a stop period and a start period. Note that, even during the suspension period, when the detection function unit 60 detects that the birds and beasts have been captured, the wireless communication function unit 70 shifts to an activated state and transmits the captured information to the relay station 100.

  FIG. 3 is a diagram illustrating an example of the schedule information. In the example shown in FIG. 3, the activation period is a period Ta, and the suspension period is a suspension period Tb. After the activation period Ta has elapsed, the wireless communication function unit 70 enters the suspension period Tb, and thereafter repeats the activation period Ta and the suspension period Tb. When it is detected that a bird or animal has been captured and activated, the wireless communication function unit 70 repeats the activation period Ta and the stop period Tb using the time at which the bird and animal are detected as a start time.

  If the wireless communication function unit 70 receives the remaining battery request information from the relay station 100 during the activation, the wireless communication function unit 70 transmits response information including the remaining battery information to the relay station 100.

  The relay station 100 is a device that executes short-range wireless communication with the box trap 50. When the relay station 100 receives the captured information by short-range wireless communication with the box trap 50, the relay station 100 executes the long-range wireless communication to notify the external device of the information of the box trap 50 in which the bird and the animal are captured. I do.

  Here, the relay station 100 transmits the request information to the box trap 50 and receives the response information, thereby grasping the information on the remaining battery level of the box trap 50. The relay station 100 compares the remaining battery amounts of the box traps 50 belonging to the same group, and adjusts the schedule information in which the activation period and the suspension period are adjusted so that the difference between the remaining battery amounts of the box traps 50 is less than the threshold. Generate.

  The relay station 100 updates the schedule information of the box trap 50 by transmitting the schedule information to the box trap 50. The box trap 50 controls the start / stop of the wireless communication function unit 70 based on the updated schedule information.

  As described above, the relay station 100 generates the schedule information so that the difference between the remaining battery levels of the box traps 50 belonging to the same group is less than the threshold, and the box trap 50 generates the schedule generated by the relay station 100. Start and stop based on the information. For this reason, the boxes and traps 50 belonging to the same group have their batteries replaced at substantially the same time, so that the user can collectively replace the batteries of the box and traps 50 belonging to the same group. Efficiency can be improved.

  Next, an example of the configuration of the box trap 50 shown in FIG. 2 will be described. FIG. 4 is a functional block diagram showing the configuration of the box trap. As shown in FIG. 4, the box trap 50a includes a battery 51, a timer 52, a power management unit 53, a storage unit 55, a detection function unit 60, and a wireless communication function unit 70.

  The battery 51 is a battery that supplies power to the timer 52, the storage unit 55, the detection function unit 60, and the wireless communication function unit 70 via the power management unit 53. For example, the battery 51 corresponds to a replaceable or rechargeable battery or the like.

  The timer 52 is a timer that outputs information on the current time to the power management unit 53, the detection function unit 60, and the wireless communication function unit 70.

  The power management unit 53 is a processing unit that manages power supply to the timer 52, the storage unit 55, the detection function unit 60, and the wireless communication function unit 70. For example, the power management unit 53 always supplies power to the timer 52, the storage unit 55, and the detection function unit 60.

  The power management unit 53 stops supplying power to the wireless communication function unit 70 during the suspension period of the schedule information 55b. The power management unit 53 supplies power to the wireless communication function unit 70 during the activation period of the schedule information 55b. The activation period is followed by the suspension period, and the suspension period is followed by the activation period.

  When the power management unit 53 receives an alert indicating that birds and beasts have been captured from the detection function unit 60, the power management unit 53 determines whether the wireless communication function unit 70 is in a stop period or in a start period. When the wireless communication function unit 70 is in the suspension period, the power management unit 53 starts power supply to the wireless communication function unit 70 and outputs an alert. When the wireless communication function unit 70 is in the activation period, an alert is output to the wireless communication function unit 70.

  When the power management unit 53 receives a request for information on the remaining battery level from the wireless communication function unit 70, the power management unit 53 accesses the battery 51 and specifies the remaining battery level. The power management unit 53 outputs information on the remaining battery level to the wireless communication function unit 70.

  Further, as will be described later, the wireless communication function unit 70 updates the schedule information 55b of the storage unit 55 with the schedule information transmitted from the relay station 100. The power management unit 53 stops and starts the subsequent power supply based on the updated schedule information 55b.

  The storage unit 55 has acceleration data 55a and schedule information 55b. The storage unit 55 corresponds to a semiconductor memory element such as a random access memory (RAM), a read only memory (ROM), and a flash memory, and a storage device such as a hard disk drive (HDD).

  The acceleration data 55a is measured by the detection function unit 60. For example, the acceleration data 55a is information in which the acceleration detected by the acceleration sensor 61 is associated with the time.

  The schedule information 55b is information that defines a stop period during which the wireless communication function unit 70 stops and a start period during which the wireless communication function unit 70 starts. For example, the schedule information 55b corresponds to the one shown in FIG.

  The detection function unit 60 includes an acceleration sensor 61 and a detection unit 62. The acceleration sensor 61 is a sensor that measures acceleration data 55a of the box trap 50a. The acceleration sensor 61 outputs the detected acceleration data 55a to the detection unit 62.

  The detection unit 62 is a processing unit that detects whether birds and beasts have been captured in the box trap 50a based on the acceleration data 55a. The detection unit 62 stores the acceleration data 55a acquired from the acceleration sensor 61 in the storage unit 55.

  The detection unit 62 monitors the acceleration data 55a received from the acceleration sensor 61, and determines that a bird or animal has been captured if the acceleration of the acceleration data 55a is equal to or greater than a threshold. Note that the detection unit 62 may calculate an average value of the acceleration data 55a for each predetermined time width, and may determine that a bird or animal has been captured if the average value is equal to or greater than a threshold value. When the detection unit 62 determines that the bird or beast has been captured, the detection unit 62 outputs an alert to the power management unit 53. The detection unit 62 includes the capture time at which the bird or beast was captured in the alert.

  The wireless communication function unit 70 is a processing unit that executes short-range wireless communication with the relay station 100 while receiving power supply from the power management unit 53. As shown in FIG. 4, the wireless communication function unit 70 includes a communication unit 71, a transmission control unit 72, and a response unit 73.

  The communication unit 71 is a processing unit that executes short-range wireless communication such as Wi-Fi with the relay station 100. A transmission control unit 72 and a response unit 73, which will be described later, exchange data with the relay station 100 via the communication unit 71.

  The transmission control unit 72 is a processing unit that generates capture information and transmits the capture information to the relay station 100 when an alert is obtained from the detection unit 62 via the power management unit 53. The capture information includes capture time information, acceleration data 55a, and trap identification information. The trap identification information is information for uniquely identifying the box trap 50a.

  The response unit 73 is a processing unit that responds to a request from the relay station 100. For example, when receiving the request information requesting the notification of the remaining battery level, the response unit 73 acquires the information on the remaining battery level of the battery 51 from the power management unit 53. The response unit 73 transmits to the relay station 100 response information including the remaining battery information and the trap identification information.

  When receiving a request for updating schedule information from relay station 100, response section 73 updates schedule information 55b with the schedule information received from relay station 100.

  Next, the configuration of relay station 100 shown in FIG. 1 will be described. FIG. 5 is a functional block diagram showing the configuration of the relay station. As shown in FIG. 5, the relay station 100 includes a communication unit 110, a timer 115, a storage unit 120, and a control unit 130.

  The communication unit 110 is a processing unit that executes data communication with the box trap 50 and an external device. For example, the communication unit 110 exchanges data by executing short-range wireless communication with the box trap 50. The communication unit 110 exchanges data by executing long-distance wireless communication with an external device. The control unit 130 described later exchanges data with the box trap 50 via the communication unit 110.

  The timer 115 is a timer that outputs information on the current time to the control unit 130.

  The storage unit 120 has an acceleration table 121, a determination table 122, and a management table 123. The storage unit 120 corresponds to a semiconductor memory device such as a RAM, a ROM, and a flash memory, and a storage device such as an HDD.

  The acceleration table 121 is a table that stores the acceleration data received from each box trap 50. FIG. 6 is a diagram illustrating an example of a data structure of the acceleration table. As shown in FIG. 6, the acceleration table 121 associates trap identification information, capture time, and acceleration data. The trap identification information is information for uniquely identifying the box trap 50. The capture time is the time at which the box trap 50 has captured the bird and beast. The acceleration data is acceleration data measured by an acceleration sensor installed on the box trap 50.

  An example of the data structure of the acceleration data stored in the acceleration table 121 will be described. FIG. 7 is a diagram illustrating an example of a data structure of the acceleration data. As shown in FIG. 7, the acceleration data associates time with acceleration values of each axis (X axis, Y axis, and Z axis in a rectangular coordinate system in a three-dimensional space). The unit of the acceleration value is “mGal”.

  The determination table 122 is a table that holds information on conditions for determining the type of bird and beast. FIG. 8 is a diagram illustrating an example of the data structure of the determination table. As shown in FIG. 8, the determination table 122 associates conditions with bird and beast types.

  The condition indicates the characteristics of the acceleration sensor 61 when the box trap 50 captures a bird and beast. If the condition is satisfied, it indicates that the associated bird and beast has been captured. The bird and beast type indicates the type of the bird and beast.

For example, when all of the following conditions a1, a2, and a3 are satisfied, it is determined that the type of bird and beast captured by the box trap 50 is “boar”. When a wild boar is captured by the box trap 50, it has a habit of repeatedly moving in the X-axis direction and the Y-axis direction. The first time width is a time width set in advance by the user, and is, for example, 60 minutes.
Condition a1: In the first time width, the average value of the acceleration in one of the X-axis direction and the Y-axis direction is 200 (mGal) or more.
Condition a2: In the first time width, the average value of the other acceleration in the X-axis direction or the Y-axis direction is 100 (mGal) or more.
Condition a3: In the first time width, the average value of the acceleration in the Z-axis direction is less than 200 (mGal).

When all of the following conditions b1, b2, and b3 are satisfied, it is determined that the type of bird and beast captured by the box trap 50 is “deer”. When a deer is caught by the box trap 50, it has a habit of repeatedly jumping in the Z-axis direction (vertical direction) compared to the X-axis direction and the Y-axis direction, and has little stamina, so that it does not move much after a while. The first time width and the second time width are time widths set in advance by the user. However, the first time width <the second time width.
Condition b1: In the first time width, the average value of acceleration in the X-axis direction and the Y-axis direction is less than 200 (mGal).
Condition b2: In the first time width, the average value of the acceleration in the Z-axis direction is 200 (mGal) or more.
Condition b3: In the second time width, the average value of the acceleration in the Z-axis direction is less than 200 (mGal).

  In addition, when it does not correspond to the above-mentioned set of conditions a1 to a3 and the set of conditions b1 to b3, it is determined that birds and animals other than “boar” and “deer” have been captured.

  The management table 123 is a table that holds schedule information and the like set for each box trap 50. FIG. 9 is a diagram illustrating an example of the data structure of the management table. As shown in FIG. 9, this management table 123 associates trap identification information, remaining battery power, schedule information, position coordinates, difficulty, and belonging group.

  The trap identification information is information for uniquely identifying the box trap 50. The remaining battery level is information on the remaining battery level of the box trap 50. The schedule information is schedule information set in the box trap 50. The initial value of the schedule information is the schedule information of the initial value set in the box trap 50. The schedule information is updated by a generation unit 133 described later. The position coordinates are the position coordinates of the box trap 50.

  The difficulty level is information indicating the installation difficulty level when the box trap 50 is installed. For example, it is more difficult to install the box trap 50 on a cliff than in the case where the box trap 50 is installed on a grassland. In the present embodiment, as an example, the magnitude relation of the difficulty levels is set as the difficulty level A> B> C.

  The belonging group is information for uniquely identifying the group to which the box trap 50 belongs. The box trap 50 is set in advance according to the position coordinates and the degree of difficulty so that the box traps 50 having similar position coordinates and difficulty belong to the same group. In the example shown in FIG. 9, the box traps 50a, 50b, and 50c belong to the group 15a, and the box traps 50d, 50e, and 50f belong to the group 15b.

  Returning to the description of FIG. The control unit 130 includes a reception unit 131, a type determination unit 132, a generation unit 133, an activation control unit 134, and a transmission control unit 135. The control unit 130 can be realized by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. The control unit 130 can also be realized by hard wired logic such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

  The receiving unit 131 is a processing unit that receives capture information and response information from the box trap 50. When receiving the capture information, the reception unit 131 stores the capture time and acceleration data included in the capture information in the acceleration table 121 in association with the trap identification information. When receiving the response information, the receiving unit 131 stores information on the remaining battery level included in the response information in the management table 123 in association with the trap identification information.

  The type determination unit 132 is a processing unit that determines the type of the bird or beast captured by the box trap 50. The type determination unit 132 determines the type of the captured bird or beast based on the acceleration table 121 and the determination table 123. The type determination unit 132 outputs the determination result to the transmission control unit 135. Here, as an example, description will be made assuming that birds and beasts are captured in the box trap 50a.

  The type determination unit 132 acquires the acceleration data corresponding to the trap identification information “box trap 50a” from the acceleration table 121, and averages the accelerations of the X axis, the Y axis, and the Z axis in the first time width starting from the capture time. Calculate the value. In addition, the type determination unit 132 calculates the average value of the accelerations of the X axis, the Y axis, and the Z axis in the second time width starting from the capture time.

  The type determination unit 132 calculates an average value of the accelerations of the X axis, the Y axis, and the Z axis in the first time width, an average value of the accelerations of the X axis, the Y axis, and the Z axis in the second time width. By comparing the condition with the condition, the applicable bird / beast type is determined. The determination result of the type determination unit 132 includes trap identification information of the box trap 50 that has captured the bird and animal, capture time, information on the type of the captured bird and animal, and the like.

  The generation unit 133 is a processing unit that generates schedule information in which the activation frequency of the box trap 50 is adjusted so that the difference between the remaining battery amounts of the same group is less than the threshold value.

  The generation unit 133 refers to the management table 123 and acquires information on the remaining battery level of the box trap 50 belonging to the same group. The generation unit 133 calculates an average remaining amount of the obtained remaining battery amounts. The generation unit 133 compares the remaining battery capacity of the box traps 50 belonging to the same group with the average remaining capacity, and determines whether the box trap 50 has a battery remaining capacity that is equal to or more than the average remaining capacity and a battery remaining capacity that is less than the average remaining capacity. A box trap 50 having a quantity is specified. In the following description, the box trap 50 having the battery remaining amount equal to or higher than the average remaining amount is referred to as “first box trap”. A box trap 50 having a remaining battery level less than the average remaining level is referred to as a “second box trap”.

  The generation unit 133 updates the schedule information of the first box trap stored in the management table 123 by increasing the frequency of activating the first box trap with respect to the schedule information of the first box trap. Note that the generation unit 133 may update the schedule information by extending the activation period Ta included in the schedule information of the first box trap by a predetermined period and shortening the suspension period Tb by a predetermined period.

  FIG. 10 is a diagram (1) illustrating an example of a process performed by the generation unit. As illustrated in FIG. 10, the generation unit 133 extends the activation period Ta included in the schedule information of the first box trap by a predetermined period, and sets the activation period Ta ′ as the activation period Ta ′. In addition, the generation unit 133 shortens the suspension period Tb included in the schedule information of the first box trap by a predetermined period to set the suspension period Tb '. In the example illustrated in FIG. 10, an example in which the activation period is simply extended and the suspension period is shortened has been described. However, the present invention is not limited to this. If the activation frequency is higher than the original schedule information, The schedule information may be updated in any manner.

  The generation unit 133 updates the schedule information of the second box trap stored in the management table 123 by lowering the frequency of activating the second box trap with respect to the schedule information of the second box trap. Note that the generation unit 133 may update the schedule information by extending the activation period Ta included in the schedule information of the second box trap by a predetermined period and shortening the suspension period Tb by a predetermined period.

  FIG. 11 is a diagram (2) illustrating an example of a process performed by the generation unit. As illustrated in FIG. 11, the generation unit 133 shortens the activation period Ta included in the schedule information of the second box trap by a predetermined period to set the activation period Ta ′. In addition, the generation unit 133 extends the suspension period Tb included in the schedule information of the second box trap by a predetermined period to set the suspension period Tb '. In the example illustrated in FIG. 11, an example in which the activation period is simply shortened and the suspension period is extended is described. However, the present invention is not limited to this. If the activation frequency is lower than the original schedule information, The schedule information may be updated in any manner.

  When the schedule information is updated by the above process, the generation unit 133 outputs the trap identification information of the box trap 50 of the updated schedule information to the activation control unit 134.

  The activation control unit 134 is a processing unit that notifies the corresponding box trap 50 of the schedule information updated by the generation unit 133. The activation control unit 134 acquires the trap identification information of the corresponding box trap 50 from the generation unit 133, and acquires the schedule information corresponding to the acquired trap identification information from the management table 123. The activation control unit 134 updates the schedule information of the box trap 50 by notifying the acquired schedule information 123 to the corresponding box trap 50, and controls the activation and stop of the wireless communication function unit 70 of the box trap 50. .

  The transmission control unit 135 is a processing unit that, when acquiring the capture information from the reception unit 131 and acquiring the determination result of the type determination unit 132, transmits the acquired information to the external device. Further, the transmission control unit 135 refers to the management table 123 and periodically transmits request information to the activated box trap 50.

  Next, a processing procedure of the box trap 50 according to the present embodiment will be described. FIG. 12 is a flowchart illustrating a procedure of processing a box trap during activation. The box trap 50 repeatedly executes the processing shown in FIG. 12 during the activation period. As shown in FIG. 12, the power management unit 53 of the box trap 50 refers to the schedule information 55b (Step S10). The power management unit 53 acquires time information from the timer 52 (Step S11).

  The power management unit 53 determines whether or not it is the suspension period based on the schedule information 55b and the time information (Step S12). When it is the suspension period (Step S12, Yes), the power management unit 53 suspends the power supply to the wireless communication function unit 70 (Step S13).

  On the other hand, if it is not the suspension period (step S12, No), the power management unit 53 proceeds to step S14. When receiving the request information from the relay station 100, the wireless communication function unit 70 of the box trap 50 transmits response information (including information on the remaining battery level) (step S14).

  When receiving the schedule information from the relay station 100, the wireless communication function unit 70 updates the schedule information 55b (step S15). When the detection function unit 60 detects that the birds and beasts have been captured, the wireless communication function unit 70 transmits the capture information to the relay station 100 (step S16), and proceeds to step S10.

  FIG. 13 is a flowchart illustrating a procedure of processing a stopped box trap. The box trap 50 repeatedly executes the processing shown in FIG. 13 during the suspension period. As shown in FIG. 13, the power management unit 53 of the box trap 50 refers to the schedule information 55b (Step S20). The power management unit 53 acquires time information from the timer 52 (Step S21).

  The power management unit 53 determines whether or not it is the activation period based on the schedule information 55b and the time information (Step S22). If it is during the activation period (Step S22, Yes), the power management unit 53 starts power supply to the wireless communication function unit 70 (Step S23).

  On the other hand, when the power management unit 53 is not in the startup period (No at Step S22), the power management unit 53 proceeds to Step S24. The power management unit 53 determines whether or not the detection function unit 60 has detected that a bird or animal has been captured (step S24). If the power management unit 53 has not detected that the detection function unit 60 has captured birds and beasts (No in step S24), the power management unit 53 ends the process.

  On the other hand, when the power management unit 53 detects that the detection function unit 60 has captured birds and beasts (Yes in step S24), the power management unit 53 starts power supply to the wireless communication function unit 70 (step S25). The wireless communication function unit 70 of the box trap 50 transmits the captured information to the relay station 100 (Step S26).

  Next, a processing procedure of the relay station 100 according to the present embodiment will be described. FIG. 14 is a flowchart illustrating the processing procedure of the relay station according to the present embodiment. As shown in FIG. 14, the transmission control unit 135 of the relay station 100 transmits request information to the activated box trap 50 (step S101). The reception unit 131 of the relay station 100 receives the response information (Step S102), and updates the information on the remaining battery level in the management table 123 (Step S103).

  The generation unit 133 of the relay station 100 updates the schedule information in which the activation frequency of the box trap 50 is adjusted so that the difference in the remaining battery levels of the same group is less than the threshold (Step S104). The activation control unit 134 of the relay station 100 notifies the updated schedule information to the box trap 50 (Step S105).

  Next, effects of the relay station 100 according to the present embodiment will be described. The relay station 100 adjusts the activation frequency based on the information on the remaining battery levels of the box traps belonging to the same group so that the difference between the remaining battery levels of the box traps 50 belonging to the same group is less than the threshold. Generate information. The relay station 100 controls the start and stop of the box trap 50 by notifying the box trap 50 of the generated schedule information. For this reason, the boxes and traps 50 belonging to the same group have their batteries replaced at substantially the same time, so that the user can collectively replace the batteries of the box and traps 50 belonging to the same group. Efficiency can be improved.

  For example, if the remaining battery level of the corresponding box trap 50 is equal to or greater than the remaining battery levels of other box traps 50 in the same group, the relay station 100 raises the frequency of activating the corresponding box trap 50 above the reference frequency. Generated schedule information. On the other hand, if the remaining battery level of the corresponding box trap 50 is less than the remaining battery levels of other box traps 50 in the same group, the relay station 100 lowers the frequency of activating the corresponding box trap 50 from the reference frequency. Generated schedule information. Thereby, schedule information for equalizing the remaining battery levels of the box traps 50 belonging to the same group can be generated by a simple algorithm.

  By the way, the generation unit 133 of the relay station 100 may update the schedule information by another method. For example, the generation unit 133 calculates the average remaining amount of the remaining battery capacity of the box traps 50 belonging to the same group, and determines, from the same group, the box traps 50 in which the difference between the average remaining amount and the battery remaining amount is equal to or larger than a threshold value. For the remaining box trap 50, schedule information may be generated in which the activation frequency is adjusted so that the difference in the remaining battery level is less than the threshold. As described above, by removing the box trap 50 in which the difference between the average remaining amount and the battery remaining amount is equal to or larger than the threshold from the same group, generation of schedule information with extremely high activation frequency or schedule information with extremely low activation frequency can be suppressed.

  When the box traps 50 are classified into groups, they may be classified based on position coordinates, based on difficulty, or based on position coordinates and difficulty. For example, when classifying the box traps 50 based on the position coordinates, the relay station 100 classifies the box traps 50 in which the distance of each position coordinate is less than a threshold into the same group. For example, when classifying the box traps 50 based on the difficulty level, the relay station 100 classifies the box traps 50 having the same difficulty level into the same group.

  When the relay station 100 classifies the box traps 50 based on the position coordinates and the difficulty level, for example, after grouping based on the position coordinates, the relay station 100 groups the box traps 50 included in the same group based on the difficulty level. .

  By the way, of the processes described in the present embodiment, all or a part of the processes described as being performed automatically can be manually performed, or the processes described as being performed manually can be performed. All or part can be performed automatically by a known method. In addition, the processing procedures, control procedures, specific names, and information including various data and parameters shown in the above documents and drawings can be arbitrarily changed unless otherwise specified.

  For example, in the above embodiment, as an example, the case where the relay station 100 generates schedule information and notifies the box trap 50 of the schedule information is described, but the present invention is not limited to this. For example, a server that manages a plurality of relay stations 100 may generate the schedule information.

  In addition, each processing function performed by each device can be realized in whole or in part by a CPU and a program analyzed and executed by the CPU, or can be realized as hardware by wired logic.
