In this order, the presence / absence of an object on the watering side in front of the sprinkler device is determined. Next, the operation of this embodiment having the above configuration will be described with reference to FIG. At this gas station, the humidity sensor 3 below the canopy 2 always monitors the humidity inside the gas station, and the external humidity sensor 4 provided on the ground inside the gas station premises monitors the humidity at the gas station ground (step SP1). ). On the other hand, the control circuit 41 determines whether the humidity of the atmosphere in the gas station detected by the humidity sensor 3 or the humidity of the ground of the gas station detected by the external humidity sensor 4 is lower than a predetermined humidity, that is, the site of the gas station is dry. Whether or not it is determined (step SP2). When the humidity of the atmosphere in the gas station and the humidity of the gas station ground are not lower than the predetermined humidity, that is, when it is determined that the gas station site is not dry, the process returns to step SP1 and the humidity sensor 3 and the external humidity sensor 4 are used. Continue to monitor humidity. On the other hand, in step SP2, if the humidity of the atmosphere in the gas station is below a predetermined humidity or if the humidity of the ground of the gas station is below a predetermined humidity, that is, if it is determined that the site of the gas station is dry, the control circuit 41 sets the sprinkler devices 11 and 12 with identification code NO. 1 to determine the presence or absence of an object on the sprinkling side in front of the device before the start of water sprinkling (step SP3). Next, the control circuit 41 resets the built-in timer to start clocking (step SP4), and outputs the alarm / emergency stop box 7 alarm 8 on the island 5.

Thereafter, the control circuit 41 determines whether or not the object sensing infrared sensors 20 and 24 of the sprinkler devices 11 and 12 are in a non-operating state, that is, whether or not there is an object on the watering side of the sprinkler devices 11 and 12 (step SP6). ). If there is no object on the sprinkler side of both sprinkler devices 11 and 12 or on the sprinkler side of either one of the sprinkler devices, the sprinkler of the sprinkler device with no substance on the sprinkler side is activated. As a result, the sprinkler of the activated sprinkler device is connected to the gas station area.
As a result of sprinkling water on the 10A side, it is possible to prevent the generation of static electricity from the ground inside the site. In this case, since the top of the sprinkler is covered by the cover, it is possible to prevent the water discharged from the water discharge part of the sprinkler from being scattered into the air and splashing on the refueling operator, the refueling customer, the vehicle, etc. With the filter on the water discharge side, the discharge water can be diffused and flow on the ground on the site (Step SP
7). On the other hand, if there is an object on the sprinkler side of both sprinkler devices 11 and 12 or on the sprinkler side of either one of the sprinkler devices, the sprinkler of the sprinkler device having the object on the sprinkler side is deactivated (step SP8). Next, the control circuit 41 determines the sprinkler device to determine the presence or absence of an object on the sprinkling side in front of the device by the identification code NO.
Then, the sprinkler devices 13 and 14 having the identification code No. 2 are set (step SP9). Thereafter, the control circuit 41 determines whether or not the time measured by the built-in timer, which has started the time measurement in step SP4, has reached a predetermined time set in advance (step
SP10), if the predetermined time has not been reached, whether or not the identification code n of the sprinkler device for determining the presence or absence of an object on the watering side in front of the device has reached the maximum identification code m (NO.3 in this embodiment). It is determined (step SP11). If the identification code of the sprinkler device to determine the presence or absence of the object on the watering side has reached NO.3, while returning to the processing of step SP3, if the identification code has not reached NO.3, the above step, Return to processing of SP6. On the other hand, when the time measured by the built-in timer reaches the preset predetermined time in step SP10, the control circuit 41 stops the alarm 8 started in step SP5. As a result, it is possible to confirm the end of the sprinkling work in the gas station (step SP12). When the alarm 8 is stopped, the sprinkler of the sprinkler device that has been activated is stopped, and the sprinkling work is completed (step SP13).
