Description

  The present invention relates to a control system.

  Conventionally, paddy field farmers have managed the water level of the paddy field in order to keep the concentration of the pesticide and fertilizer within a certain range when the paddy field is sprayed with pesticides and fertilizers. In general, the management of the water level has been troublesome because it was necessary for the worker of the paddy farmer to actually visit the paddy field to be managed and measure the water level visually.

  Therefore, a management system that manages the water level of the paddy field in a remote place without an operator visiting the paddy field has been proposed (for example, see Patent Document 1). In the management system of this patent document 1, a data collection device that collects water level data that is water level data of a paddy field is provided in the paddy field, and a center server that communicates with the data collection device via a wireless communication network is provided. The water level data collected by the data collection device is wirelessly transmitted to the center server via the wireless communication network after being provided at a remote location with respect to the paddy field, and the water level of the paddy field is managed on the center server side.

  However, in the management system of Patent Document 1, since it is necessary to provide a data collection device in a paddy field, for example, it is difficult to route a power line for supplying power to the data collection device, and commercial power cannot be used. In addition, a battery is provided, and the data collection device is operated using the power of the battery. And when operating a data collection device with the electric power of a battery, as a device for reducing the work frequency of battery replacement or charging work, a solar power generation panel is provided in the data collection device. A technique for charging a battery with generated power has been proposed.

  Alternatively, as another contrivance for reducing the work frequency of the battery charging work, a technique for preserving battery power, such as used in a mobile phone system, that is, between a data collection device and a center server. Therefore, it has been proposed to devise an intermittent communication based on the timer of these devices.

JP 2009-236638 A

  When using the technology for charging the battery with the power generated by the photovoltaic power generation panel, the size of the photovoltaic power generation panel is set to be relatively large. Since it is easy to be damaged and the water level of the paddy field could not be stably managed in a remote place, there was room for improvement in terms of stably managing the water level of the paddy field.

  When the intermittent communication technique is used, an accurate RTC (real-time clock) module is essential, and communication between devices cannot be established if the timers of the devices deviate from each other. However, in order to obtain an accurate time, each device needs a means for obtaining an accurate time such as GPS. However, there is a problem that electric power is required to operate this mechanism.

  Recently, with the aging of farmers, the number of fields that have been entrusted to agricultural corporations for management has increased, and the distance between paddy fields is often more than a few kilometers away. There was also a problem that radio waves did not reach.

  The present invention has been made in view of the above, and an object of the present invention is to provide a control system capable of stably performing control relating to a target area.

  In order to solve the above-described problems and achieve the object, the control system according to claim 1 includes a control device that performs control related to a target area and a moving device that moves relative to the control device. The moving device includes a moving-side output unit that outputs an energy wave, and the control device generates a power by using the energy wave output from the moving-side output unit. And a control-side control unit that performs control relating to the target area when the control-side power generation unit generates power.

  The control system according to claim 2 is the control system according to claim 1, wherein the control device collects target area information that is information about the target area, and the control side collection. Control side transmission means for transmitting the target area information collected by the means, and the mobile device comprises movement side reception means for receiving the target area information transmitted by the control side transmission means, and the control When the control-side power generation unit generates power, the side-side control unit is configured to control the target region information collected by the control-side collection unit via the control-side transmission unit as the control on the target region. Control to send to.

  According to a third aspect of the present invention, there is provided the control system according to the second aspect, wherein the control-side control means generates at least the electric power generated by the control-side power generation means when the control-side power generation means generates power. Control is performed to transmit the target area information collected by the control-side collection unit to the moving-side reception unit via the control-side transmission unit using power other than that.

  The control system according to claim 4 is the control system according to any one of claims 1 to 3, wherein the moving device is a flying object flying in the air.

  The control system according to claim 5 is the control system according to any one of claims 1 to 4, wherein the energy wave is an ultrasonic wave.

  According to the control system of the first aspect, when the control-side power generation means generates power, the control related to the target area is performed. Therefore, for example, the control-side power generation means should perform the control related to the target area. Since it can be used as a trigger, control relating to the target area can be performed only at an appropriate timing to be controlled, and for example, the power of the battery (that is, the battery) of the control device can be preserved. Can be done automatically. In addition, for example, since it is not necessary to provide a photovoltaic power generation panel having a large area, the shape of the control device can be changed to a shape that is not easily damaged by wind and rain (for example, a bar shape standing in a target region).

  According to the control system of claim 2, when the control-side power generation means generates power, the target area information collected by the control-side collection means is transmitted to the movement-side reception means via the control-side transmission means. For this reason, for example, the target area information can be acquired using the mobile device, so that the target area can be managed using the target area information at a remote location away from the control device. In addition, for example, since the mobile device can move to the vicinity of the control device and acquire target area information, it is not necessary to provide a communication network over the entire area between the control device and the above-mentioned remote place (that is, radio waves reach far away). It is not necessary to install a high-power wireless communication device), and it is possible to collect a wide range of target area information that exceeds the reach of the radio wave of communication equipment that does not require a license, and the installation cost of the control system In addition, management costs can be reduced.

  Further, according to the control system of the third aspect, since control is performed to transmit the target area information using at least power other than the power generated by the control-side power generation means, for example, the target area information is wirelessly transmitted. Since a sufficient amount of power charged in a battery (that is, a battery) or the like can be used as transmission power for transmission, the communication distance between the mobile device and the control device can be extended, and the target area information can be It can be reliably transmitted from the control device to the mobile device.

  Further, according to the control system of the fourth aspect, since the moving device is a flying object that flies in the air, for example, the moving device can move three-dimensionally in the space. It can move at high speed regardless of an object (for example, a building or a person on the ground), and can quickly acquire target area information from the control device. In addition, the target area information can be acquired without interfering with social activities (for example, walking, work, etc.) of people on the ground.

  Further, according to the control system of the fifth aspect, since the energy wave is an ultrasonic wave, for example, a building (for example, a storage for storing agricultural tools in paddy fields) is provided around the control device. Even when the control device is covered with a cover such as a waterproof case, the ultrasonic waves are propagated to the control device and can be reliably generated by the control device. Further, for example, since it does not interfere with wireless electric signals from other devices in the vicinity of the monitoring area, for example, communication by the wireless electric signals is not hindered.

It is a flowchart of an information collection process. It is a flowchart of an information transmission process. It is a flowchart of an information acquisition process.

(Processing-Information collection processing)
First, the information collection process will be described. FIG. 3 is a flowchart of the information collection process (in the following description of each process, step is abbreviated as “S”). The “information collecting process” is a process performed by the information collecting apparatus 20, and is a process for collecting and recording water level information. The timing for starting this information collection process is arbitrary, but here, for example, the switch control unit 212 of the timekeeping element 21 grasps the current time based on the timekeeping result of the timer unit 211, and then, for example, a predetermined time (for example, , 30 minutes, etc.) will be described after starting.

Specifically, the power of the communication element side power supply 243 is supplied to the memory reading unit 241 and the wireless communication unit 242 by turning on the communication element side switch 244 of FIG.

  Returning to FIG. 4, in SB2, the memory reading unit 241 of the communication element 24 reads information. The information to be read out is arbitrary as long as it includes the water level information, but here, for example, the information collection device 20 includes an identification information storage unit (not shown), and the identification information storage unit includes: In the following, it is assumed that “ID2” is recorded as information collection device identification information that is information for uniquely identifying itself. Specifically, for SB2, the memory reading unit 241 uses the power from the communication element side power supply 243 in FIG. 2 to read out information collection device identification information from an identification information storage unit (not shown), and also in SA3 in FIG. The measurement time and water level information written (that is, accumulated) is read out. Here, for example, a combination of “ID2” and measurement time and water level information shown in FIG. 2 (for example, a combination of “08: 0” and “10 cm”, and a combination of “08:30” and “11 cm”) Etc.).

  Returning to FIG. 4, in SB3, the wireless communication unit 242 of the communication element 24 generates a collection-side signal. Here, the “collection side signal” is a signal transmitted from the information collection device 20 of FIG. 2 to the flying object 10, and is, for example, a signal including at least information collection device identification information, measurement time, and water level information. . Specifically, for SB3, a collection-side signal including information collection device identification information, measurement time, and water level information read in SB2 is generated using the power from the communication element-side power supply 243 in FIG. Here, for example, a combination of “ID2” and measurement time and water level information shown in FIG. 2 (for example, a combination of “08: 0” and “10 cm”, and a combination of “08:30” and “11 cm”) Etc.) is generated.

  Returning to FIG. 4, in SB4, the wireless communication unit 242 of the communication element 24 wirelessly transmits the collection-side signal. Specifically, the collection side signal generated in SB3 is wirelessly transmitted to the flying object 10 using the power from the communication element side power supply 243 in FIG. Note that, regarding the strength of the collecting-side signal transmitted wirelessly here, the transmitted collecting-side signal passes through the “peripheral area of the information collecting device 20” in consideration of the fact that high power from the communication element-side power source 243 can be used. However, in this case, for example, an area within a radius of 50 m to 100 m centered on the information collecting device 20 (that is, “information collecting device 20 In the following description, it is assumed that the collection-side signal is set so as to reach an area wider than the “peripheral area”. Here, for example, using the power from the communication element side power supply 243, the wireless communication unit 242 sends a combination of “ID2” and the measurement time and water level information shown in FIG. 2 (for example, “08: 0” and A collection-side signal including a combination of “10 cm” and a combination of “08:30” and “11 cm” is transmitted to the flying object 10 by radio in the 920 MHz band. The aircraft 10 that is flying between the “peripheral area of the information collection device 20” and the arrival point is reached along the flight route.

  Returning to FIG. 4, in SB5, the information in the collection-side storage unit 231 is deleted. Although the processing subject performing this processing is arbitrary, here, for example, it is assumed that the memory reading unit 241 in FIG. 2 also has a function of erasing information in the collection-side storage unit 231. The following description will be made on the assumption that the unit 241 performs the process of SB5. Specifically, for SB5, the information read in SB2 is deleted from the collection-side storage unit 231 using the power from the communication element-side power supply 243 in FIG.

  Returning to FIG. 4, in SB6, the switch control unit 253 of the trigger element 25 cuts off the power. Specifically, the power from the communication element side power supply 243 to the memory reading unit 241 and the wireless communication unit 242 is cut off by turning off the communication element side switch 244 of FIG. This completes the information transmission process. The timing for executing this SB6 is arbitrary as long as it is after SB5. Here, for example, the switch control unit 253 of the trigger element 25 and the memory reading unit 241 newly erase information. Immediately after receiving the signal from the memory reading unit 241, the SB6 may be executed.

(Processing-Information acquisition processing)
Next, the information acquisition process will be described. FIG. 5 is a flowchart of the information acquisition process. The “information acquisition process” is a process in which the flying object 10 acquires at least water level information from the information collection device 20. The timing for starting the information acquisition process is arbitrary, but here, for example, after the power source of the flying object 10 is turned on and the flight route is set for the flying object 10 using a known method, It will be described after starting up that 10 starts and starts executing when flight starts. As for the flight route of the flying object 10, a management center several kilometers away from the information collection device 20 is used as a departure point and an arrival point, and the management center and the “peripheral area of the information collection device 20” (for example, the drawing of FIG. 1). The following description will be made on the assumption that a route that reciprocates between the information collecting apparatus 20) on the left side is set. As for the flying object 10, the position of the vehicle 10 is grasped by using the detection result of the current position detection unit 14 or the like, and depending on the position grasping mechanism, the accurate position is corrected by the imaging result of the camera 13. The flight is performed by automatic control along the set flight route. However, since the known control method can be used for this automatic control as described above, detailed description of this automatic control is omitted.

  First, as shown in FIG. 5, the flight side control unit 16 of the flying vehicle 10 outputs an ultrasonic wave in SC1. Specifically, the ultrasonic wave generation unit 12 in FIG. 2 is activated, and ultrasonic waves are output from the ultrasonic wave generation unit 12. Here, for example, when the flying object 10 enters the range of a specific distance (for example, within 10 m from the information collecting apparatus 20 m) while facing the information collecting apparatus 20 along the flight route, the reaction from the information collecting apparatus 20 is performed. Until there is, continues to output ultrasonic waves intermittently.

  Returning to FIG. 5, in SC <b> 2, the flight-side control unit 16 of the flying object 10 determines whether or not the collection-side signal transmitted in SB <b> 4 in FIG. 4 has been received wirelessly. Specifically, the flight side communication unit 11 in FIG. 2 is monitored, and based on the monitoring result, it is determined whether or not the collection side signal from the information collection device 20 has been received wirelessly. If the flight-side communication unit 11 does not receive the collection-side signal wirelessly, it is determined that the collection-side signal is not received wirelessly (NO in SC2), and the collection-side signal is received wirelessly. SC2 is repeatedly executed until it is determined that it has been completed. Moreover, when the flight side communication part 11 received the collection side signal wirelessly, it determines with having received the collection side signal wirelessly (YES of SC2), and transfers to SC3. Here, for example, a combination of “ID2” and measurement time and water level information shown in FIG. 2 (for example, a combination of “08: 0” and “10 cm”, and a combination of “08:30” and “11 cm”) Etc.) and the flight side communication unit 11 receives the collection side signal wirelessly, it is determined that the collection side signal transmitted in SB3 is received wirelessly.

  Returning to FIG. 5, in SC3, the flight side control unit 16 of the flying vehicle 10 stops the ultrasonic wave. Specifically, the operation of the ultrasonic generator 12 in FIG. 2 is stopped, and the output of the ultrasonic wave from the ultrasonic generator 12 is stopped.

  Returning to FIG. 5, in SC4, the flight-side control unit 16 of the flying vehicle 10 stores information. Specifically, information collection device identification information, measurement time, and water level information are acquired from the collection-side signal received at SC2, and each acquired information is stored in the flight-side storage unit 15 of FIG. Here, for example, from the acquisition side signal received by SC2, “ID2” and a combination of measurement time and water level information shown in FIG. 2 (for example, a combination of “08: 0” and “10 cm”, and “08 : 30 ”and“ 11 cm ”, etc.) and each piece of acquired information is stored. This completes the information acquisition process. After completing this information acquisition process, the flying object 10 flies to the management center that is the arrival place, and each piece of information (for example, information stored in the flight-side storage unit 15 of the flying object 10 at the management center). It is possible to manage the state of the paddy field using the collection device identification information, measurement time, and water level information.

(Effect of embodiment)
As described above, according to the present embodiment, when the power generation unit 251 generates power, the control related to the target region (for example, paddy field) is performed, so that the power generation unit 251 generates power, for example, the control related to the target region. Since it can be used as a trigger to be performed, control relating to the target area (for example, generation and transmission of a collection-side signal) is performed only at an appropriate timing at which control is to be performed. Therefore, it is possible to stably control the target area. In addition, for example, since it is not necessary to provide a large-area solar power generation panel, the shape of the information collection device 20 can be made to be a shape that is not easily damaged by wind and rain (for example, a bar shape standing in the target region). .

  In addition, when the power generation unit 251 generates power, the target area information (for example, water level information) collected by the measurement unit 222 is transmitted to the flight-side communication unit 11 via the wireless communication unit 242. Since the target area information can be acquired using 10, the target area can be managed using the target area information at a remote place away from the information collection device 20. In addition, for example, since the flying object 10 can move to the vicinity of the information collecting device 20 and acquire target area information, there is no need to provide a communication network throughout the information collecting device 20 and the above-mentioned remote place (that is, It is not necessary to install a high-power wireless communication device that can reach far distances), and it is possible to collect a wide range of target area information that exceeds the limit of the reach of the communication facilities with unlicensed radio wave output, The installation cost and management cost of the control system 1 can be reduced.

  In addition, since control is performed to transmit the target area information using the power of the communication element side power source 243 that is at least power other than the power generated by the power generation unit 251, for example, transmission power for wirelessly transmitting the target area information Since a sufficient amount of electric power charged in the communication element side power source 243 can be used as the communication element side power supply 243, the communication distance between the flying object 10 and the information collecting device 20 can be extended, and the target area information is used as the information collecting device. 20 can be reliably transmitted to the flying object 10.

  Further, since the moving device is the flying object 10 that flies in the air, for example, the flying object 10 can move three-dimensionally in the space, so that an obstacle on the ground (for example, a building or a person on the ground) ) Regardless of whether the target area information is acquired from the information collecting device 20 or not. In addition, the target area information can be acquired without interfering with social activities (for example, walking, work, etc.) of people on the ground.

  In addition, since the energy wave is an ultrasonic wave, for example, when a building (for example, a storage for storing agricultural tools in a paddy field) is provided around the information collection device 20, or the information collection device 20 Even when the cover is covered with a cover such as a waterproof case, the ultrasonic wave is propagated to the information collecting device 20 and can be reliably generated by the information collecting device 20. Further, for example, during a period in which the flying object 10 outputs ultrasonic waves and wireless communication is not performed between the flying object 10 and the information collecting device 20 (hereinafter referred to as a pre-communication period) Since it does not interfere with wireless electric signals from other devices, at least in the “pre-communication period”, for example, communication by the wireless electric signals is not hindered.

When the collecting element side switch 225 is always turned on, or the position of the collecting element side switch 225 is short-circuited, the switch control unit 212 turns on the collecting element side switch 225. Instead, the switch control unit 212 may output a trigger signal for operating the measurement unit 222 or the memory writing unit 223.

  In addition, the standby power of the communication element 24 (specifically, the memory reading unit 241 and the wireless communication unit 242) of FIG. 2 in the above embodiment (that is, consumed in cases other than the case where the processing specified in the embodiment is performed).

Alternatively, a termination code may be attached. In such a configuration, in SB4 in the process of FIG. 4 that is repeatedly performed, it is determined whether the information has been transmitted by paying attention to the delimiter or the termination code, and only the untransmitted information is transmitted. May be.

(About stopping ultrasonic waves)
Further, in SC2 of FIG. 5 of the above embodiment, header information is included in the collected signal transmitted wirelessly, and when only this header information is received, the collected signal is received wirelessly. It may be determined and the process may proceed to SC3. In such a configuration, it is possible to quickly determine that the acquisition-side signal has been received at SC2, and to quickly stop the ultrasonic wave, so that the power source on the flying object 10 side is wasted.

(Additional effects)
According to the control system described in appendix 1, when the control-side power generation unit generates power, control related to the target area is performed. For example, the fact that the control-side power generation means generates power is a trigger for performing control related to the target area. Therefore, it is possible to perform control related to the target area only at an appropriate timing at which the control should be performed, for example, to preserve the power of the battery (that is, the battery) of the control device, so that the control related to the target area is stable. Can be done. In addition, for example, since it is not necessary to provide a photovoltaic power generation panel having a large area, the shape of the control device can be changed to a shape that is not easily damaged by wind and rain (for example, a bar shape standing in a target region).

  According to the control system described in appendix 2, when the control-side power generation unit generates power, the target area information collected by the control-side collection unit is transmitted to the movement-side reception unit via the control-side transmission unit. For example, since the target area information can be acquired using the mobile device, the target area can be managed using the target area information at a remote location that is remote from the control device. In addition, for example, since the mobile device can move to the vicinity of the control device and acquire target area information, it is not necessary to provide a communication network over the entire area between the control device and the above-mentioned remote place (that is, radio waves reach far away). It is not necessary to install a high-power wireless communication device), and it is possible to collect a wide range of target area information that exceeds the reach of the radio wave of communication equipment that does not require a license, and the installation cost of the control system In addition, management costs can be reduced.

  According to the control system described in appendix 3, since control for transmitting the target area information is performed using at least power other than the power generated by the control-side power generation unit, for example, transmission for wirelessly transmitting the target area information Since a sufficient amount of electric power charged in a battery (that is, a battery) or the like can be used as electric power, the communication distance between the mobile device and the control device can be extended, and the target area information is obtained from the control device. It can be reliably transmitted to the mobile device.

  According to the control system described in appendix 4, since the moving device is a flying object flying in the air, for example, the moving device can move three-dimensionally in the space. It is possible to move at high speed regardless of the building or the person on the ground) and to quickly acquire the target area information from the control device. In addition, the target area information can be acquired without interfering with social activities (for example, walking, work, etc.) of people on the ground.

  According to the control system described in appendix 5, since the energy wave is an ultrasonic wave, for example, a building (for example, a storage for storing farm tools in paddy fields) is provided around the control device. Alternatively, even when the control device is covered with a cover such as a waterproof case, the ultrasonic waves are propagated to the control device and can be reliably generated by the control device. Further, for example, since it does not interfere with wireless electric signals from other devices in the vicinity of the monitoring area, for example, communication by the wireless electric signals is not hindered.
