  However, as described above, when the insect repellent is applied only on the paved road, the insect repellent on the paved road is easily removed under climatic conditions such as wind and rain, so that the insect repellent effect can be exhibited only for a very short period. There is a problem.

  Also in the technique of Patent Document 1, the insect repellent component of the cement milk for permeation and the water permeable resin mortar held in the surface layer portion of the pavement is gradually changed depending on the climatic conditions such as wind, rain, and even the heat of the sun. Evaporated and removed. For this reason, although it lasts longer than the case where only an insect repellent is used, an insect repellent effect cannot be exhibited in a short time. Therefore, it is necessary to frequently apply insect repellent ingredients, peel off the permeation cement milk and water permeable resin mortar, and newly apply the permeation cement milk and water permeable resin mortar containing insect repellent ingredients. There is a problem that man-hours are required.

  The present invention has been made in view of such a background, and provides an insect repellent pavement system capable of retaining an insect repellent component on a pavement while suppressing work man-hours and exhibiting an insect repellent effect as long as possible. The task is to do.

Embodiments of the present invention will be described below with reference to the drawings.
<Configuration of First Embodiment>
FIG. 1A is a cross-sectional view showing a characteristic configuration of an insect repellent pavement system according to the first embodiment of the present invention, FIG. 1B is a cross-sectional view of a permeable paved road as a pavement, and FIG. 1C is a pavement. It is a sectional view of a drainage paved road.
The feature of the insect repellent pavement system 10 shown in FIG. 1 (a) is that a self-propelled vehicle 30 that stores a powdery or granular insect repellent 25 is run on the road surface of the permeable pavement road 20 {FIG. 1 (b)}. However, the insect repellent 25 is sprayed.

  As shown in FIG. 1 (b), a permeable paved road 20 has a roadbed 22 laminated on an underground roadbed 21, and a porous asphalt (porous asphalt) mixture as a paved body on the roadbed 22. 23 is laminated. The main purpose of the roadbed 21 is to sufficiently support the distributed load transmitted through the roadbed 22 from the traffic load of a vehicle or the like traveling on the road surface. The roadbed 22 plays a role of distributing traffic load and transmitting it to the roadbed 21.

  The porous asphalt mixture 23 is an asphalt pavement having a water permeability and a large porosity. For this reason, when rain 15 falls, the rain water 15 enters the gap of the porous asphalt mixture 23 as shown by the arrow Y1 and flows downward, soaks into the road bed 21 via the roadbed 22 and is drained. The Alternatively, there is a structure in which a drainage path 22a is provided on the roadbed 22 to facilitate drainage. In this way, water does not collect on the road surface.

  As described above, since the porous asphalt mixture 23 has a flow path (see the arrow Y1) by a gap, as shown in FIG. 1A, a powdery or granular insect repellent 25 smaller than the gap is sprayed on the road surface. In this case, the insect repellent 25 enters the gap and falls by gravity or is pushed by the wind and falls deeply into the roadbed 22 side. The insect repellent 25 that has entered the voids exhibits an insect repellent effect in which the insect repellent component evaporates and diffuses into the air through the road surface, and the insects do not come from the grass flora and the like.

  However, the insect repellent component of the insect repellent 25 can be appropriately selected from general insect repellent components. As a general insect repellent component, there are those composed of components such as plant essential oils and synthetic insecticides. Plant essential oil has an insecticidal effect such as lemongrass, fennel, turmeric, geranium, eucalyptus, and hiba. Synthetic insecticides include deet (DEET), but also include pyrethroids such as ciphenothrin and profluthrin, neonicotinoid agents such as imidacloprid and dinotefuran, and organic phosphorus agents such as fenitrothion and propetanephos. These insect essential oils, synthetic insecticides, and other components may be used alone or in any combination to form microcapsules for the insect repellent 25. However, it is necessary to consider the adverse effects on the human body.

  Instead of the permeable paved road 10, a drainable paved road 29 shown in FIG. The drainage pavement 29 has a structure in which a base layer 27 that does not allow water to pass through is laminated on a roadbed 28, and a drainage pavement 26 having a gap is laminated on the base layer 27. Also on this road 29, when the insect repellent 25 is sprayed on the road surface as described above, the insect repellent 25 enters and is held in the gaps of the drainage pavement 29, so that an insect repellent effect is exhibited.

  Next, the insect repellent pavement system 10 for spraying the insect repellent 25 onto the permeable pavement 20 will be described with reference to FIG. The water-permeable paved road 20 is referred to as a road 20, and the insect repellent pavement system 10 is hereinafter referred to as a system 10. The road 20 is assumed to be a promenade in the park in this example.

In addition to the road 20 and the self-propelled vehicle 30 described above, the system 10 includes a guide line 40 laid as a center line on the road 20 and a solar power generation device 50.
The induction line 40 generates an S-pole or N-pole magnetic field line (also referred to as magnetism), and is laid on the road 20 by solidifying or half-embedding a magnetic material such as magnetic tape or magnetic paint. . The guide line 40 is laid from the vicinity of the base of the support column 53 for installing the solar power generation device 50 provided near the base end of the road 20 to the vicinity of the tip of the road 20. The guidance line 40 is detected by a guidance sensor 39d (see first and second guidance sensors 39c and 39d shown in FIG. 3) using an electromagnetic induction element of the traveling vehicle 30, whereby the traveling vehicle 30 is moved to the road 20 It is possible to run on the top automatically.

Next, the structure of the self-propelled vehicle 30 will be described. The self-propelled vehicle 30 has a box shape, and a left wheel 31a and a right wheel 31b are rotatably attached to lower left and right side centers of the box shape as shown in FIG. One shaft of a left drive motor 32a with a shaft protruding left and right is attached to the inner center of the left wheel 31a, and one shaft of a right drive motor 32b with a shaft protruded to the left and right is attached to the inner center of the right wheel 31b. Is attached. Between the left and right drive motors 32a and 32b, an elongated cylindrical rotary roller 33 is attached so as to connect the other shafts of the motors 32a and 32b with a straight line.
The motors 32a and 32b are rotationally driven in synchronism, and the left and right wheels 31a and 31b rotate and the rotating roller 33 rotates in accordance with the rotational driving. A brush (circular brush) is planted on the entire surface of the rotating roller 33 in a circular manner.

  FIG. 3A is a right side surface 30b of the traveling direction shown in FIG. As shown in FIG. 3A, on the left and right side surfaces of the self-propelled vehicle 30, a total of four auxiliary wheels 34 are attached to the front and rear of each side surface via a support portion 34g so that the travel angle can be varied. The four auxiliary wheels 34 can travel in contact with the road 20 together with the left and right wheels 31a and 31b which are driving wheels. Each support portion 34g is equipped with a travel angle variable portion 34i (see FIG. 4), and the travel angle of the auxiliary wheel 34 can be freely changed.

  A human sensor 36 is attached to the front surface 30 c and the rear surface 30 d of the self-propelled vehicle 30. The human sensor 36 is an optical sensor such as an infrared sensor, a thermal sensor, or an ultrasonic sensor, and has a function of detecting a human body in the front-rear direction of the self-propelled vehicle 30. For example, the human sensor 36 detects the presence of a person within a detection area several meters from the self-propelled vehicle 30 by detecting a heat ray radiated from the human body with a pyroelectric element.

  3B and 3C are cross-sectional views when the left and right centers of the self-propelled vehicle 30 are cut vertically in the front-rear direction. As shown in FIG. 3 (c), the self-propelled vehicle 30 includes a front bottom plate 37c extending downwardly from the front inner surface toward the center toward the rear, and a rear side inner surface to the front side. A rear bottom plate 37d extending in a downwardly inclined manner near the center is disposed in abutment state via a predetermined gap G1.

  A rotating roller 33 is disposed below the gap G1 with a predetermined interval. As shown in FIG. 3B, a plate-shaped shutter 38a that closes the entire gap G1 is disposed between the gap G1 and the rotating roller 33. A part of the shutter 38a is attached to a shutter opening / closing part 38 that horizontally moves the shutter 38a in the front-rear direction so that the shutter 38a can be freely stored. That is, as shown in FIG. 3B, the shutter opening / closing unit 38 protrudes from the shutter 38a to close the gap G1, and from this state, the shutter 38a moves backward as shown in FIG. An opening / closing operation for opening G1 is performed. The operation of closing the gap G1 with the shutter 38a is called a shutter closing operation, and the operation of opening the gap G1 with the shutter 38a is called a shutter opening operation.

  Thus, the space surrounded by the two bottom plates 37c and 37d where the gap G1 is opened and closed by the shutter 38a and the four front and rear, right and left sides of the self-propelled vehicle 30 is a storage portion 30R of the insect repellent 25. When the rotating roller 33 rotates during the shutter opening operation, the insect repellent 25 stored in the storage unit 30R falls from the gap G1 while being regulated by the rotating brush of the rotating roller 33.

  A first induction sensor 39c is attached to the front side and a second induction sensor 39d is attached to the rear side at the center of the lower part of the inner surface of each of the front and rear of the self-propelled vehicle 30. Each induction sensor 39c, 39d detects a magnetism emitted from the induction line 40 using a Hall element or the like, and is fixed on the induction line 40 (FIG. 2) with an interval capable of properly detecting magnetism. Yes.

  The self-propelled vehicle 30 includes a direct current battery 42 inside and a wireless unit 41 having an antenna on the outer top surface. As shown in FIG. 4, the wireless unit 41 performs wireless communication with the mobile terminal 43. Furthermore, as shown in FIG. 2, the self-propelled vehicle 30 includes an operation unit 44 on the rear surface. The operation unit 44 is for the operator to perform operations such as turning on / off the main power source, automatic travel setting operation, manual travel setting operation, shutter opening / closing, etc., by the DC battery 42 of the self-propelled vehicle 30. An operation equivalent to this can be performed by the portable terminal 43 (FIG. 4). The mobile terminal 43 may be a dedicated wireless terminal such as a tablet or a mobile phone including a smartphone.

  However, since the on / off operation of the main power supply is an on / off operation using a mechanical contact, it is assumed that a person can press the main power button only on the operation unit 44. The main power on / off operation from the portable terminal 43 can be performed only when the main power is in the sleep state.

  Further, as shown in FIG. 4, the self-propelled vehicle 30 includes the human sensor 36, the left drive motor 32a, the right drive motor 32b, the shutter opening / closing unit 38, the first induction sensor 39c, the second induction sensor 39d, and the direct current. A control unit 45 that controls each of the battery 42, the operation unit 44, the travel angle variable unit 34 i, and the radio unit 41 is provided.

  The control unit 45 performs operation command control according to the operation by the operation unit 44 or the mobile terminal device 43 and automatic traveling control of the self-propelled vehicle 30. The automatic traveling control by the control unit 45 is such that the insect repellent 25 is stored in the storage unit 30R in a predetermined amount or more, and the self-propelled vehicle 30 returns to the DC battery 42 up to the tip of the road 20 and returns. It may be possible to carry out when power of a capacity necessary for operation is charged. Further, the storage amount of the insect repellent 25 equal to or larger than a predetermined amount is an amount capable of spraying the insect repellent 25 from the base end to the front end of the road 20. The storage amount of the insect repellent 25 is detected by a weight sensor (not shown), and the charge capacity of the DC battery 42 is detected by a charge capacity detection sensor (not shown).

  As the operation command control, the control unit 45 performs the following various controls. First, the main power is turned on / off when the main power on / off operation of the self-propelled vehicle 30 is performed by the operation unit 44. Next, control is performed so that the shutter opening / closing unit 38 performs the shutter opening / closing operation of the shutter 38a when the operation unit 44 performs the shutter opening / closing operation. Next, when automatic operation or manual travel setting operation is performed by the operation unit 44, the automatic travel or manual travel is set and executed. At the time of manual travel setting, the left and right drive motors 32a and 32b are driven to rotate when the manual travel button is pressed on the operation unit 44, and the control is stopped when the stop button is pressed.

  As the automatic travel control, the control unit 45 performs the following various controls. First, when the main power supply is turned on, the vehicle 30 is controlled to automatically travel forward. Control is performed so that the shutter opening operation is performed after a predetermined time from the automatic running. Next, during the automatic traveling, the traveling of the self-propelled vehicle 30 is controlled so that the first induction sensor 39c always detects the magnetism emitted from the induction line 40. This control is executed while the travel angle variable unit 34 i changes the travel angles of the four auxiliary wheels 34.

  Next, the control part 45 performs control which stops the left-right drive motor 32a, 32b, when a person exists in the front or back position away from the self-propelled vehicle 30 by the predetermined distance. At this time, a brake (not shown) may be applied. Next, when the self-propelled vehicle 30 detects a predetermined number of broken lines of the guide line broken line portion 40a (see FIG. 2) at the tip of the guide line 40, the left and right drive motors 32a and 32b are once stopped and then rotated in the reverse direction. Control to drive. This control causes the self-propelled vehicle 30 to stop and then travel backward. When traveling backward, a shutter closing operation may be performed.

  Next, the traveling of the self-propelled vehicle 30 is controlled so that the second induction sensor 39d always detects the magnetism emitted from the induction line 40 when traveling backward. This control is also executed while the travel angle variable unit 34 i changes the travel angles of the four auxiliary wheels 34. Next, when the self-propelled vehicle 30 detects a predetermined number of broken lines in the guide line broken line portion 40b (see FIG. 2) at the base end of the guide line 40, the left and right drive motors 32a and 32b are controlled to stop while decelerating. As a result, the self-propelled vehicle 30 stops at a predetermined position.

  At the time of this stop, the first connector 42a of the DC battery 42 shown in FIG. 4 is connected to the second connector 52a connected to the charge controller 52 described later. The first connector 42a is connected to a positive electrode end and a negative electrode end (not shown) of the DC battery 42.

  Although not shown, the first connector 42a is fixed to the outside of the rear surface of the self-propelled vehicle 30, and the conductive wire connected to the internal DC battery 42 is connected to the first connector through a through hole (not shown) on the rear surface. 42a. The second connector 52a is fixed to the support column 53 (FIG. 2). This fixed position is on the rear side of the self-propelled vehicle 30 and at the same height as the first connector 42a. Thus, when the self-propelled vehicle 30 stops, the first connector 42a is connected to the second connector 52a. That is, as described above, when the left and right drive motors 32a and 32b are decelerated, if the control unit 45 detects that the first and second connectors 42a and 52a are connected, the self-propelled vehicle 30 is stopped. It has become.

  The first and second connectors 42a and 52a may be connected by a person. Moreover, you may provide a hut so that the self-propelled vehicle 30 may be accommodated in the state which the 1st and 2nd connectors 42a and 52a were connected. The hut may be provided with an automatic door that is automatically locked.

Next, the solar power generation device 50 will be described with reference to FIG.
The solar power generation device 50 includes a solar power generation panel 51 and a charge controller (or charge / discharge controller) 52.
The solar power generation panel 51 is erected on a dedicated road 20 made by branching from the road 20 via a support column 53. The solar power generation panel 51 is installed on the top of a pillar 53 having a predetermined height with the solar power generation surface 51a facing the sun (not shown), and generates power in response to sunlight irradiation to generate electric power. In addition, the guide line 40 is extended and laid from the exclusive road 20 to the road 20 of the park that originally exists.

The charge controller 52 is wired between the photovoltaic power generation panel 51 and the DC battery 42 (FIG. 4) of the self-propelled vehicle 30, and is disposed, for example, near the lower side of the photovoltaic power generation panel 51 as shown in FIG. The
The charge controller 52 performs charge control for charging by converting the DC voltage generated by the photovoltaic power generation panel 51 into the voltage of the DC battery 42. In addition, the charge controller 52 performs prevention of overcharge of the DC battery 42, load cutoff control when the DC battery 42 is at a low voltage, and control of voltage backflow prevention to the photovoltaic power generation panel 51.

<Operation of First Embodiment>
Next, the operation | movement of the automatic spraying of the insect repellent 25 to the water-permeable pavement road 20 by the insect repellent pavement system 10 of 1st Embodiment is demonstrated with reference to the flowchart shown in FIG.5 and FIG.6. However, it is assumed that the repellent 25 is fully stored in the storage unit 30 </ b> R of the self-propelled vehicle 30, and the DC battery 42 is fully charged with the power generated by the solar power generation panel 51.

  In step S <b> 1 shown in FIG. 5, it is assumed that an automatic driving operation of the self-propelled vehicle 30 is performed after the main power-on operation of the self-propelled vehicle 30 is performed by the operator, for example, in the portable terminal 43. When these operation signals are received by the radio unit 41 of the self-propelled vehicle 30, in step S2, the main power of the self-propelled vehicle 30 is turned on by the control of the control unit 45 and the traveling is automatically started. At this time, the control unit 45 controls the self-propelled vehicle 30 to travel along the guide line 40.

  Next, in step S3, under the control of the control unit 45, a shutter opening operation is performed after a predetermined time from the start of automatic traveling in step S2. As a result, the shutter 38a moves backward to open the gap G1 of the reservoir 30R. At this time, since the self-propelled vehicle 30 is traveling, the rotating roller 33 is rotating, and the insect repellent 25 falls along the rotating roller 33 and is sprayed on the road 20. A part of the sprayed insect repellent 25 falls into the gap {see FIG. 1 (a)} of the porous asphalt mixture 23.

  In step S4, the insect repellent component of the insect repellent 25 that has dropped onto the road 20 and into the air gap evaporates and diffuses into the air. Since the insect repellent component is diffused, insects such as mosquitoes do not come on the road 20.

  In step S <b> 5, while the self-propelled vehicle 30 is traveling, the control unit 45 determines whether or not the human sensor 36 senses a person. If a person is detected as a result of this determination, the self-propelled vehicle 30 is stopped under the control of the control unit 45 in step S6. At this time, since the rotation of the rotary roller 33 is also stopped, the spraying of the insect repellent 25 is also stopped. On the other hand, if a person is not detected, automatic driving is continued as it is, and the process proceeds to step S9 described later.

  After the self-propelled vehicle 30 stops in step S6, in step S7, it is determined by the control unit 45 whether or not the human sensing state of the human sensor 36 has been released. If canceled, in step S8, the self-propelled vehicle 30 travels forward in the same direction as before the stop by the control of the control unit 45. At this time, since the rotating roller 33 rotates, the spraying of the insect repellent 25 is resumed. On the other hand, if not canceled, the process returns to step S6 and the stop of the self-propelled vehicle 30 continues.

  Next, in step S9, the control unit 45 determines whether or not a predetermined number of broken lines of the guide line broken line portion 40a (see FIG. 2) at the tip of the guide line 40 has been detected by the first guidance sensor 39c. If it is not detected, the determination operation continues.

  On the other hand, if detected, the left and right drive motors 32a and 32b are stopped and rotated in the reverse direction under the control of the control unit 45 in step S10 shown in FIG. By this control, the self-propelled vehicle 30 travels backward. At this time, a shutter closing operation may be performed. When traveling backward, the control unit 45 detects the guidance line 40 with the second guidance sensor 39 d and controls the self-propelled vehicle 30 to travel along the guidance line 40.

  In step S <b> 11, the controller 45 determines whether or not the human sensor 36 has sensed a person while the self-propelled vehicle 30 is traveling backward. If a person is detected as a result of this determination, the self-propelled vehicle 30 stops under the control of the control unit 45 in step S12. On the other hand, if a person is not detected, automatic driving is continued as it is, and the process proceeds to step S15 described later.

  After the self-propelled vehicle 30 stops in step S12, it is determined in step S13 whether the human sensor of the human sensor 36 has been released by the control unit 45. If canceled, in step S14, the self-propelled vehicle 30 travels backward in the same direction as before the stop by the control of the control unit 45.

The nozzle n <b> 1 communicates with the inside of the first and second pipes 82 and 83 and is integrally provided, and is arranged in a state of protruding from the top of the pipes 82 and 83 to the surface of the paved road 70. FIG. 8 is a view showing a configuration of the insect repellent solution supply device 80 and a cross section of the paved road 70 cut along the first pipe 82.

Insect repellent pavement system 60 is characterized in that an insect repellent solution 89 (see FIG. 8) is sprayed onto pavement road 70 from each nozzle n1 of first and second pipes 82 and 83 embedded in pavement road 70. It is in the point.
The nozzle n1 has an extremely small opening, and the liquid can be ejected in the form of a mist by sending the liquid to the nozzle n1 at a predetermined flow rate and pressure.

  The insect repellent solution 89 sprayed from the nozzle n1 is diffused in a hollow space, falls on the upper surface of the paved road 70, and is held for a predetermined time. The insect repellent component of the insect repellent solution 89 diffused in the hollow exhibits an insect repellent effect in the hollow, and the insect repellent solution 89 that has fallen on the upper surface of the paved road 70 evaporates and diffuses into the air to exert a repellent effect. . The insect repellent solution 89 is obtained by dissolving an insect repellent component equivalent to the insect repellent 25 of the first embodiment in water.

Further, a human sensor 81 is embedded in the vicinity of the surface layer of the paved road 70 as shown in FIG.
The human sensor 81 is formed by arranging a plurality of piezoelectric elements in the width direction of the road 20, and generates electric power when a person steps on the piezoelectric elements, and a control unit 90 generates a signal (human detection signal) based on the generated electric power. Output. The human sensor 81 may use a pressure sensor or a strain gauge, and output a human detection signal to the control unit 90 when a person steps on the pressure sensor or the strain gauge.

  Next, the insect repellent solution supply apparatus 80 shown in FIG. 8 will be described. The insect repellent solution supply device 80 includes first and second pumps 84 and 85, suction pipes 82b and 83b connected to the suction sides of the first and second pumps 84 and 85, electromagnetic valves 86 and 87, and an insect repellent solution. The control unit 90 includes a storage tank 88 in which 89 is stored, and a timer 91.

The first pump 84 has a suction side connected to the suction pipe 82 b and a discharge side connected to the first pipe 82. The suction pipe 82 b is inserted to the vicinity of the inner bottom surface of the storage tank 88 through the electromagnetic valve 86 on the way.
The second pump 85 has a suction side connected to the suction pipe 83 b and a discharge side connected to the second pipe 83. The suction pipe 83 b is inserted to the vicinity of the inner bottom surface of the storage tank 88 through the electromagnetic valve 87 on the way.

  The control unit 90 controls the electromagnetic valves 86 and 87 to open and activates the first and second pumps 84 and 85 when a person is detected by the human sensor 81. By this control, the insect repellent solution 89 stored in the storage tank 88 is sucked by the first and second pumps 84 and 85 and discharged to the first and second pipes 82 and 83. When the control unit 90 is not performing control, the electromagnetic valves 86 and 87 are closed and the first and second pumps 84 and 85 are stopped.

  In addition, the control unit 90 causes the timer 91 to time-measure when the human sensor 81 senses a person, and when the timer 91 passes the first time (first time), the first and second pumps 84 and 85 are operated. Is stopped, and the electromagnetic valves 86 and 87 are closed.

  The first timekeeping time means that the insect repellent solution 89 discharged to the first and second pipes 82 and 83 by starting the first and second pumps 84 and 85 reaches the tips of the pipes 82 and 83, and It is preferable to set the time until a predetermined amount is injected from the nozzles n1 of the pipes 82 and 83 onto the paved road 70. The sprayed insect repellent solution 89 is diffused and diffused in a hollow space, falls on the upper surface of the paved road 70, is held for a predetermined time, and then evaporates into the hollow space.

  Further, the control unit 90 starts from the human sensor 81 until the timer 91 stops after a predetermined second time (second time) elapses after the timer 91 has passed the first time. Even if the human detection signal is transmitted, the opening control of the electromagnetic valves 86 and 87 and the activation control of the first and second pumps 84 and 85 are not performed. That is, it is preferable that the second time keeping time is a time until the insect repellent effect of the insect repellent solution 89 that is dropped and held on the paved road 70 is not exhibited.

<Operation of Second Embodiment>
Next, the automatic spraying operation of the insect repellent solution 89 on the paved road 70 by the insect repellent pavement system 60 of the second embodiment will be described. However, it is assumed that the first timekeeping time of the timer 91 is set to 10 minutes and the second timekeeping time is set to 50 minutes, and the control unit 90 is in a standby state.

  First, when a person steps on the human sensor 81, a human detection signal is transmitted to the control unit 90. When receiving the human detection signal, the control unit 90 controls the electromagnetic valves 86 and 87 to be opened and activates the first and second pumps 84 and 85. By this control, the insect repellent solution 89 stored in the storage tank 88 is sucked by the first and second pumps 84 and 85 and discharged to the first and second pipes 82 and 83.

  The discharged insect repellent solution 89 is sprayed from each nozzle n1 while being supplied to the tips of the first and second pipes 82 and 83. The sprayed insect repellent solution 89 is diffused and diffused in a hollow space, and falls on the upper surface of the paved road 70 and is held for a predetermined time, and evaporates into the hollow space during this time. As a result, an insect repellent effect that prevents insects from coming from the grassland or the like is exhibited.

  Thereafter, assuming that the time measured by the timer 91 exceeds 10 minutes of the first time-measured time, the control unit 90 stops the first and second pumps 84 and 85 and closes the electromagnetic valves 86 and 87. I do. As a result, the first and second pumps 84 and 85 are stopped, and the electromagnetic valves 86 and 87 are closed. After that, if the timer 91 is in a timing operation, that is, if 50 minutes of the second timing time has not elapsed after 10 minutes of the first timing time, no matter how many times the human detection signal is transmitted. The control unit 90 does not perform the opening control of the electromagnetic valves 86 and 87 once closed and the start control of the stopped first and second pumps 84 and 85. Thereafter, when the timer 91 stops after 50 minutes of the second timing, the control unit 45 enters a standby state waiting for the next human detection signal. When a human detection signal is transmitted in this standby state, the above-described automatic spraying operation is repeated again.

<Effects of Second Embodiment>
The insect repellent pavement system 60 of the second embodiment described above is embedded along the paved road 70 through the nozzle n1 that is embedded along the paved road 70 as a paved body and protrudes from the upper surface of the circuit surface to the upper surface of the paved road 70. A plurality of at least one pipe 82 or 83 (two in this embodiment), a storage tank 88 for storing an insect repellent solution 89 in which an insect repellent component is dissolved, and a pipe for storing the stored insect repellent solution 89 into the pipes 82 and 83 It was set as the structure provided with the control part 90 which controls the starting and stop of the 1st and 2nd pumps 84 and 85 to discharge, and the 1st and 2nd pumps 84 and 85.

  According to this configuration, when the first and second pumps 84 and 85 are activated by the control unit 90, the insect repellent solution 89 stored in the storage tank 88 is sucked by the first and second pumps 84 and 85. It is discharged to the pipes 82 and 83 and reaches the tips of the pipes 82 and 83. At this time, it is injected onto the paved road 70 from each nozzle n1. The sprayed insect repellent solution 89 is diffused and diffused in a hollow space, and falls on the upper surface of the paved road 70 and is held for a predetermined time, and evaporates into the hollow space during this time. Due to this evaporation and diffusion, it is possible to exhibit an insect-proof effect that insects do not approach the paved road 70. In addition, since the control unit 90 automatically controls the spraying of the insect repellent solution 89, the work of a person who sprays the insect repellent solution 89 becomes unnecessary. Therefore, the insect repellent component can be held on the paved road 70 while suppressing the work man-hours, and the insect repellent effect can be exhibited.

  In addition, the paved road 70 includes a human sensor 81 for detecting a person, and the control unit 90 performs control to activate the first and second pumps 84 and 85 when the human sensor 81 detects a person. Control is performed to stop the first and second pumps 84 and 85 after elapse of a predetermined first time (first time) from the start-up control.

  According to this configuration, only when a person enters the paved road 70 and is detected by the human sensor 81, the first and second pumps 84 and 85 are activated for a predetermined time, and the stored insect repellent solution 89 is stored. Is sprayed from the nozzles n1 of the first and second pipes 82 and 83 onto the paved road 70, so that the insect repellent solution 89 is not wasted.

  Further, the control unit 90 does not detect the first and second pumps even if the human sensor 81 detects a person until a predetermined second time (second time) elapses after the first time has elapsed. 84 and 85 are controlled not to start.

  According to this configuration, the time (holding time) during which the insect repellent solution 89 sprayed onto the paved road 70 by the activation of the first and second pumps 84 and 85 is held on the paved road 70 is measured as the second time count. If the time is set, the first and second pumps 84 and 85 are not wastefully activated during the holding time. For this reason, the stored insect repellent solution 89 can be prevented from being used wastefully.

  In addition, the number of the first and second pipes 82 and 83 can be one or three or more according to the width of the road 20. Moreover, if the length of each piping 82 and 83 is long, you may insert the pump for relay in the middle. Furthermore, the human sensor 81 may be provided with an optical sensor such as an infrared sensor, a thermal sensor, an ultrasonic sensor, or the like in a place such as a pillar that cannot be reached by humans, other than being embedded in the paved road 70. .

  Furthermore, instead of the paved road 70, if the first and second pipes 82 and 83 are embedded in a well-known water-retained paved road that retains moisture for a long time and each nozzle n1 protrudes from the surface, the spraying of the insect repellent solution 89 is performed. The solution 89 that subsequently falls on the water retentive pavement can be held on the water retentive pavement for a long time. Thereby, the insect-proof effect can be exhibited for a long time.

  As mentioned above, although embodiment of this invention was described in detail with reference to drawings, this invention is not limited to this, In the range which does not deviate from the main point of invention, it can change suitably.
