The important monitoring position information includes a patrol number numbered for each flight route, position information of a plurality of important monitoring positions corresponding to the patrol number (for example, latitude and longitude on the flight area map), and between each important monitoring position. This is movement section information for identifying a movement section (including movement section information between the robot port 2 where the flying robot 3 takes off and landing and the first and last important monitoring positions). The flight altitude range is an altitude range (for example, a range of 3 to 7 m from the ground surface) in which flight is allowed for each moving section of the flight path. The flight altitude condition is a condition of a flight altitude corresponding to manned or unmanned, and is set as a higher altitude at least when manned than when unmanned. The traveling schedule is a schedule indicating which important monitoring positions in the monitoring area E are to be visited in what order, and is set in advance for each monitoring area E by operation of the monitoring console 5a of the monitoring center 5.

In addition to these, various parameters for controlling the flight of the flying robot 3 and various programs for realizing the functions of the flight control device 4 are stored.

  The storage unit 42 includes a plurality of areas E1 to E5 in the monitoring area E and a traveling point as information for determining whether the area corresponding to the moving section selected by the manned / unmanned judging means 43a described later is present. Information in which the (important monitoring positions P1 to P5) or the movement sections M1 to M6 are associated and tabulated is stored in advance. Specifically, for example, in the circulation route of the circulation number 1 in FIG. 1, a plurality of areas E1 to E5 in the monitoring area E and the important monitoring positions P1 to P5 or the movement sections M1 to M6 that are the circulation points are associated with each other. The converted information is stored in the storage unit 42.

  The manned / unmanned determination means 43a determines whether the user exists in the target area in the monitoring area E or not. Specifically, in the areas E1 to E5 of the monitoring area E shown in FIG. 1, in order to detect an intruder into the monitoring area E from the outside, for example, an infrared sensor, a laser sensor, a microwave sensor, an ultrasonic sensor, A security device (not shown) configured with various detection sensors such as an image sensor is arranged. When the manned unmanned determination means 43a determines whether or not the security device is set in the security set mode for detecting intrusion into the target area (E1 to E5), and determines that the security set mode is set. It is determined that the target areas (E1 to E5) of the monitoring area E are unmanned.

  Here, the security set mode refers to detection when various detection sensors as a security device detect an intruding object (for example, a suspicious person or a suspicious vehicle) entering the target area (E1 to E5) of the monitoring area E. In this mode, an abnormality is determined by an intruding object in the target areas (E1 to E5) of the monitoring area E in accordance with the detection signal of the sensor. On the other hand, the security release mode is a mode in which abnormality determination based on an intruding object is not performed even when a detection signal is input from a detection sensor as a security device.

  Note that the security device is not limited to a detection sensor, and any device that can grasp the presence / absence of intrusion for each of the areas E1 to E5 of the monitoring area E, for example, manages an entry / exit history for each of the areas E1 to E of the monitoring area E. It can also be configured with an entrance / exit management device. In addition, the manned / unattended determination unit 43a is not limited to this, and may be any device as long as it can determine whether a user is present in the target area. For example, it may be determined whether it is manned or unmanned based on whether or not this can be detected by means for receiving the user's RF-ID.

  When the altitude determination means 43b moves to the important monitoring positions P1 to P5, the altitude determining means 43b has a flight altitude range (cyclic altitude range) corresponding to the flight route (movement section M1 to M6) to the important monitoring positions P1 to P5, and manned unmanned. The flight altitude is determined according to the flight altitude condition corresponding to the determination result of the determination means 43a. For example, when it is determined that it is manned, the upper limit value of the flight altitude range or an altitude in the vicinity thereof is determined as the flight altitude, and when it is determined that it is unmanned, the lower limit value of the flight altitude range or an altitude in the vicinity thereof is determined as the flight altitude. Note that how the flight altitude is set from the flight altitude range by manned or unmanned people is stored in advance as a flight altitude condition.

  The altitude table generating unit 43c stores the flight altitude determined by the altitude determining unit 43b in the storage unit 42 as an altitude table associated with the flight path (movement sections M1 to M6).

  The flight control unit 43d acquires flight state information, position information, and altitude information from the flying robot 3 via the communication unit 41, and sends control signals related to the flight of the flying robot 3 such as the movement target position and speed of the flying robot 3. It transmits to the flying robot 3 via the communication unit 41 and controls the flight of the flying robot 3. For example, if the flying altitude of the flying robot 3 is equal to or higher than a preset altitude, the speed is controlled so that the flying robot 3 flies at a high speed (for example, 5 to 15 m / s). Further, if the flying altitude of the flying robot 3 is less than the set altitude, the flying robot 3 flies at a low speed (for example, 2 to 3 m / s: a speed that can be avoided when an obstacle is detected) below the reference speed. Control the speed.

  The imaging control means 43e controls imaging by the imaging unit 16 of the flying robot 3, and an imaging permission signal (imaging prohibition release signal) based on altitude information at the current position acquired from the flying robot 3 via the communication unit 41. Alternatively, a photographing prohibition signal is transmitted to the flying robot 3 via the communication unit 41. For example, when the altitude information of the flying robot 3 at the current position is equal to or higher than the set altitude, a shooting prohibiting signal for prohibiting shooting by the shooting unit 16 is transmitted to the flying robot 3 via the communication unit 41. On the other hand, when the altitude information of the flying robot 3 at the current position is less than the set altitude, a shooting permission signal (shooting prohibition release signal) that permits shooting by the shooting unit 16 is transmitted to the flying robot 3 via the communication unit 41. To do. Note that the imaging control unit 43e may transmit an imaging angle control signal for controlling the imaging angle of the imaging unit 16 to the flying robot 3 via the communication unit 41 as necessary.

  Further, the imaging control means 43e determines whether or not the illuminance around the flying robot 3 in flight is equal to or less than the set illuminance using the luminance information and illuminance information of the captured image acquired from the flying robot 3, and the determination result Based on the altitude information described above, an on / off control signal for turning on / off the illumination 17 of the flying robot 3 is transmitted to the flying robot 3. For example, when the flying robot 3 is flying at night below the set illuminance and the flying robot 3 is flying above the set altitude, an off control signal is sent via the communication unit 41 to prohibit the lighting 17 from being turned on. 3 to send. In contrast, when the flying robot 3 is flying at night below the set illuminance and the flying robot 3 is flying below the set altitude, the on-control signal is sent via the communication unit 41 to turn on the illumination 17. Send to the robot 3.

  When a determination result indicating whether or not the illuminance around the flying robot 3 in flight is equal to or lower than the set illuminance is transmitted from the flying robot 3, the illumination 17 of the flying robot 3 is turned on / off based on the determination result. The imaging control means 43b transmits an on / off control signal to be turned off to the flying robot 3. The current time can also be used to determine whether the illuminance around the flying robot 3 in flight is equal to or lower than the set illuminance.

  The state confirming unit 43f confirms the state of the flying robot 3, and periodically confirms whether or not the function of the flying robot 3 is normal when the flying robot 3 is waiting at the robot port 2.

[About monitoring center configuration]
As shown in FIG. 2, the monitoring center 5 includes a monitoring console 5a such as a terminal device that receives an image captured by the flying robot 3 via the flight control device 4 and displays the received image. The monitoring center 5 can also instruct the start of altitude setting processing described later by operating the monitoring console 5a. Further, the monitoring center 5 operates the monitoring console 5a at the discretion of the monitoring person to fly the flight robot 3 to an arbitrary place (flight route instruction, movement target position / speed instruction, takeoff instruction, return instruction). Etc.). For example, when the monitor finds an intruding object (for example, a suspicious vehicle or a suspicious person) into the monitoring area E from the video displayed on the monitor table 5a, the monitor operates the monitor table 5a to set the flying robot 3 on the site. The movement target position (latitude, longitude) to be directed to is set, and the set movement target position is transmitted as a control signal to the flying robot 3 via the flight control device 4.

[About advanced settings processing]
Next, altitude setting processing executed by the flight control device 4 will be described with reference to FIG. The altitude set by the altitude setting process is used when the flying robot 3 makes a patrol flight in which a monitoring operation is performed by stopping at a critical monitoring position for a certain period of time while moving at a plurality of important monitoring positions. Here, an altitude setting process in the case where the flying robot 3 patrols the flight route (movement sections M1 to M6) of the patrol number 1 shown in FIG. 1 will be described as an example.

  In the altitude setting process of FIG. 5, when a tour start is input manually from the remote monitoring center 5 a predetermined time before the tour start time set as the tour schedule, the preset travel parameter generation time is set. It starts at any timing. For example, in the case of a patrol schedule for patrol number 1 shown in FIG. 1 patrolling every 2 hours from 9:00, if the predetermined time is 15 minutes, for example, 8:45 15 minutes before 9:00. Start the altitude setting process.

  When the altitude setting process starts at the above timing, the patrol point information of the patrol number that the flying robot 3 patrols is read (ST1). When the flying robot 3 patrols the flight route of the tour number 1 shown in FIG. 1, the tour point information (coordinate information) of the tour number 1, that is, the important monitoring position information of the important monitoring positions P <b> 1 to P <b> 5 is read from the storage unit 42. .

  Next, information on the flight altitude range (touring altitude range) for each moving section based on the patrol point information is read (ST2). In the flight route of the patrol number 1 shown in FIG. 1, the moving section M1 between the roboport 2 and the first important monitoring position P1, the moving sections M2, M3, M4, M5 between the important monitoring positions P1 to P5, the last Information on the flight altitude range in the movement section M6 between the important monitoring position P5 and the roboport 2 is read from the storage unit 42.

  Next, a section (moving section) from the robot port 2 to the first point (first important monitoring position) is selected (ST3). In the flight route with the circulation number 1 shown in FIG. 1, the movement section M1 from the roboport 2 to the first important monitoring position P1 is selected.

  Next, it is determined whether the area corresponding to the selected section is manned or unmanned (ST4). When the movement section M1 from the roboport 2 to the first important monitoring position P1 is selected in the flight route of the tour number 1 shown in FIG. 1, the presence or absence of the area E1 corresponding to the movement section M1 is determined. The determination of whether the area E1 corresponding to the movement section M1 is manned or unmanned can be made in the movement section M1 if the corresponding security device is set to the security set mode for detecting entry into the area E1 corresponding to the movement section M1. It is determined that the corresponding area E1 is unattended. On the other hand, if it is set to the security release mode that does not detect entry into the area E1 corresponding to the movement section M1, it is determined that the area E1 corresponding to the movement section M1 is manned.

  Next, the flight altitude (cyclic altitude) of the selected section is determined from the flight altitude range according to the manned and unmanned state (ST5). When it is determined that the area E1 corresponding to the selected movement section M1 is manned in the flight route of the traveling number 1 shown in FIG. 1, for example, the upper limit value of the flight altitude range is determined by the flight altitude. On the other hand, when it is determined that the area E1 corresponding to the selected movement section M1 is unmanned, for example, the lower limit value of the flight altitude range is determined as the flight altitude.

  Next, the determined altitude is stored in the altitude table of the storage unit 42 as the flight altitude of the selected section (ST6). For example, when the selected section is the moving section M1 in the flight route of the traveling number 1 shown in FIG. 1 and the lower limit value of the flight altitude range is determined as the flight altitude, the determined flight altitude is stored in the altitude table of the storage unit 42. To remember.

  And it is discriminate | determined whether the flight altitude of the area to all the points corresponding to a circulation number was set (ST7). In the case of the patrol route of the patrol number 1 shown in FIG. 1, the flight altitudes of the sections M1 to M6 to all the points P1 to P5 corresponding to the patrol number 1 (and the reference position P0 of the last roboport 2) are set. If it is determined that there is no, a section to the next point is selected, and the process proceeds to ST4. Then, the processing of ST4 to ST7 is repeatedly executed until the flight altitudes of the sections M1 to M6 up to all the points P1 to P5 (and the reference position P0 of the last roboport 2) corresponding to the patrol number 1 are set.

  As described above, the flight control device 4 executes the above-described altitude setting process before the flight of the flying robot 3. When the flight control device 4 instructs the flying robot 3 to make a patrol, the flight control device 4 obtains the position information of each important monitoring position in the flight path of the patrol number to be visited and the flight altitude of the altitude table corresponding to each important monitoring position. Transmit to the flying robot 3. The flying robot 3 circulates each important monitoring position on the flight path while avoiding obstacles around the flight altitude according to the position information transmitted from the flight control device 4 and the flight altitude for each flight path (movement section). Security information (for example, a photographed image by the photographing unit 16) is collected at each important monitoring position and returned to the robot port 2. The security information collected by the flying robot 3 is transmitted to the monitoring center 5 via the flight control device 4 and displayed on the monitoring console 5a of the monitoring center 5 for safety confirmation.

  By the way, the flying robot 3 may be caused to fly to an arbitrary movement target position in the monitoring area for purposes other than patrol. In this case, the altitude determination means 43b sets the center position of the roboport 2 where the flying robot 3 stands by as the reference position P0, and sets the altitude when the movement target position is further away from the reference position P0 to set the altitude to be higher. Store in the altitude table. As a result, the flying robot 3 is set so that the moving altitude is higher as the moving target position from the reference position P0 is farther. Therefore, the flying robot 3 can move at high speed in the sky with almost no obstacles, and can safely reach the moving target position. It can move at high speed and shorten the arrival time.

  In the above-described embodiment, the case where the flight control device 4 executes the altitude setting process shown in FIG. 5 has been described as an example, but the altitude setting process may be executed by the flying robot 3 itself. In this case, the position information, flight path, important monitoring position information (position coordinate information), flight altitude range (traveling altitude range), and flight altitude conditions of the roboport 2 are stored in the storage unit 21 of the flying robot 3. Further, the flying robot 3 is manned to determine whether a user is present in the monitoring area depending on whether the security device is set in a security set mode for detecting entry into the target area (E1 to E5). Manned and unmanned judging means (equivalent to the manned and unmanned judging means 43a of the flight control device 4) for performing unmanned judgment, and when moving to the important monitoring position, the flight altitude range corresponding to the flight path to the important monitoring position and the manned unmanned judgment Altitude determining means (corresponding to the altitude determining means 43b of the flight control device 4) for determining the flight altitude according to the flight altitude condition corresponding to the result of the above, and an altitude table in which the flight altitude determined by the altitude determining means is associated with the flight path As an altitude table generating means (corresponding to the altitude table generating means 43c of the flight control device 4) stored in the storage unit 21 as shown in FIG. To perform a constant process. As a result, the rotor control means 32b controls the rotor drive unit 12 to drive the rotor 11 so that the flying robot 3 moves at the flying altitude determined by the altitude setting process during patrol.

  Although the best mode of the flying robot control system and the flying robot according to the present invention has been described above, the present invention is not limited by the description and drawings according to this mode. That is, it is a matter of course that all other forms, examples, operation techniques, and the like made by those skilled in the art based on this form are included in the scope of the present invention.
