<Overview of Embodiment>
FIG. 1 is a diagram schematically showing a usage scene of a test device 100 according to this embodiment. The test device 100 is a device suitable for inspecting a fire sensor 10 installed in a high place such as a ceiling. The user U carries out the inspection while holding the rod-shaped support 110 that is the handle of the user U. FIG.

The test apparatus 100 tests the operation of the fire sensor 10 with the housing 120 covering the fire sensor 10 . The test apparatus 100 generates a force for adjusting the posture of the housing 120 and adjusts the upper surface of the housing 120 to face the fire sensor 10 . According to the test apparatus 100 as described above, the housing 120 can cover the fire sensor 10 by the user U moving the housing 120 of the test apparatus 100 to the vicinity of the fire sensor 10 . 120 position can be adjusted automatically. Thereby, the user U can easily perform the operation test of the fire sensor 10 . Next, such a test apparatus 100 will be described.

<Configuration Example of Test Apparatus 100>
FIG. 2 shows a configuration example of the test device 100 according to this embodiment together with the fire sensor 10. As shown in FIG. A fire sensor 10 is provided on the ceiling surface 12 . The ceiling surface 12 is an example of a ceiling provided in office buildings, factories, schools, warehouses, residences, and the like. The fire sensor 10 may be installed on a wall surface or outdoors. In addition, in this embodiment, three orthogonal axes are shown as the X-axis, the Y-axis, and the Z-axis. The test apparatus 100 includes a support section 110 , a housing 120 and a force generation section 200 .

The support part 110 is a rod-shaped member having one end attached to the housing 120 and the other end serving as a handle for the user U of the test apparatus 100 . It is desirable that the support part 110 is adjusted in length according to the height up to the position where the fire sensor 10 is installed. The support 110 may be used with a length of, for example, 10m to 20m. The support portion 110 may be configured by connecting a plurality of rod-shaped members.

The housing 120 has an opening 122 for encasing the fire sensor 10 therein and members for performing operational tests. FIG. 2 shows an example in which an opening 122 whose opening surface is the upper surface of the housing 120 substantially parallel to the XY plane is provided. In this case, the user U holds the handle of the support section 110 by hand, and when the position of the housing 120 in the X and Y directions substantially matches the position of the fire sensor 10, the housing 120 is moved upward (in the +Z direction). ), the fire sensor 10 can be covered with the housing 120 .

The force generator 200 generates force for adjusting the posture of the housing 120 . In the example of FIG. 2, it is desirable that the force generating section 200 generate forces in two directions, such as the X direction and the Y direction, which are substantially parallel to the XY plane. Alternatively, the force generator 200 may generate force in one direction or in three or more directions substantially parallel to the XY plane.

<Example of Perspective View of Housing 120>
FIG. 3 shows an example of a perspective view of the housing 120 according to this embodiment. FIG. 3 is an example showing members inside the housing 120 from the opening 122 of the housing 120 . A simulated fire generating section 130 , a fan 140 , and an imaging section 150 are provided inside the housing 120 .

The simulated fire generator 130 generates a simulated fire. The simulated fire generator 130 generates simulated smoke by, for example, continuously pouring liquid paraffin little by little into the ultrasonic vibrator. Alternatively, the simulated fire generator 130 may generate simulated smoke by encapsulating liquid paraffin in a cylinder pressurized with nitrogen or the like, and activating a valve button of the cylinder to spray the liquid paraffin. Also, the simulated fire generating section 130 may have a heater.

The fan 140 rotates and blows air to send simulated smoke generated by the simulated fire generator 130 to the fire sensor 10 . In addition, when the simulated fire generating unit 130 has a heater, the fan 140 may blow the heat generated by the simulated fire generating unit 130 to the fire sensor 10 as hot air.

The imaging unit 150 is a camera that images the fire sensor 10 . The imaging unit 150 captures an image for identifying the relative position of the housing 120 with respect to the fire sensor 10 . For example, when the housing 120 is positioned appropriately to cover the fire sensor 10, the imaging unit 150 may position the fire sensor 10 substantially in the center of the image captured by the imaging unit 150. 150, the angle of view, etc. are determined in advance. As a result, by detecting the distance between the position of the fire sensor 10 and the center in the image captured by the imaging unit 150, the position from the appropriate position of the housing 120 to the current position of the housing 120 can be determined. The amount of deviation can be specified.

In addition to these, the housing 120 is provided with a control unit 160 (not shown). The control unit 160 controls the simulated fire generating unit 130 , the fan 140 and the imaging unit 150 to test the fire sensor 10 . Also, the control unit 160 controls the force generation unit 200 based on the image captured by the imaging unit 150 . The control unit 160 will be described later.

<First Configuration Example of Force Generation Unit 200>
FIG. 4 shows a first configuration example of the force generating section 200 according to this embodiment. The force generator 200 of the first configuration example generates force for adjusting the attitude of the housing 120 using reaction wheels. The force generator 200 has a rotating disk 210, a motor (not shown) that rotates the rotating disk 210, and a motor drive circuit (not shown) that drives the motor. The force generator 200 has a combination of one or more rotating discs 210, a motor, and a motor drive circuit.

The force generating unit 200 desirably has two rotating discs 210 whose rotating surfaces are two surfaces perpendicular to the opening surface of the opening 122 of the housing 120 and perpendicular to each other. FIG. 4 shows an example in which the force generating section 200 has a first rotating disk 210a that generates a force in the X-axis direction and a second rotating disk 210b that generates a force in the Y-axis direction. Arrows indicate examples of the rotation directions of the first rotating disk 210a and the second rotating disk 210b.

The first rotating disk 210a rotates around a rotation axis substantially parallel to the Y-axis. The direction of rotation of the first rotating disk 210a may be clockwise, or alternatively counterclockwise. For example, when the first rotating disk 210a rotates at a constant angular velocity, the force generated by the first rotating disk 210a is almost zero. Here, it is assumed that the first rotating disk 210a is rotating clockwise.

From this state, when the angular velocity of the first rotating disk 210a increases, the first rotating disk 210a generates force in the -X direction due to counter torque. In other words, the force generator 200 generates a force that moves the housing 120 in the -X direction. Also, when the angular velocity of the first rotating disk 210a decreases, the first rotating disk 210a generates a force in the +X direction due to counter torque. In other words, the force generator 200 generates a force that moves the housing 120 in the +X direction.

The second rotating disk 210b rotates around a rotation axis substantially parallel to the X axis. As with the first rotating disk 210a, the second rotating disk 210b may rotate clockwise, or may rotate counterclockwise. When the second rotating disk 210b rotates at a constant angular velocity, the force generated by the second rotating disk 210b is almost zero. Here, it is assumed that the second rotating disk 210b is rotating counterclockwise.

From this state, when the angular velocity of the second rotating disk 210b increases, the second rotating disk 210b generates force in the -Y direction due to counter torque. In other words, the force generator 200 generates a force that moves the housing 120 in the -Y direction. Also, when the angular velocity of the second rotating disk 210b decreases, the second rotating disk 210b generates a force in the +Y direction due to counter torque. In other words, the force generator 200 generates a force that moves the housing 120 in the +Y direction.

The control unit 160 controls the motor of the force generation unit 200 to increase or decrease the rotation speed of the rotating disk 210, thereby changing the direction and magnitude of the force generated by the force generation unit 200, thereby changing the housing. Adjust 120 posture. Note that the control unit 160 may stop the rotating disk 210 in a steady state, and when executing the control of the force generating unit 200, start rotating the rotating disk 210 in the direction corresponding to the direction in which the counter torque is generated. may In this case, control unit 160 may reverse the direction of rotation according to the direction in which counter torque is generated. Such a control unit 160 will be described below.

<First Configuration Example of Control Unit 160>
FIG. 5 shows a first configuration example of the control unit 160 according to this embodiment. The control unit 160 has an image acquisition unit 161 , a storage unit 162 , a fire sensor detection unit 163 and a drive signal generation unit 164 . FIG. 5 shows, together with the control unit 160, a first motor drive circuit 220a that drives the motor that rotates the first rotating disk 210a, a second motor drive circuit 220b that drives the motor that rotates the second rotating disk 210b, An actuation detector 230 is also shown.

The image acquisition unit 161 acquires the image captured by the imaging unit 150 . The image acquisition unit 161 acquires images captured by the imaging unit 150 at regular intervals, for example. The image acquisition unit 161 may store the acquired image in the storage unit 162 .

The storage unit 162 may store intermediate data generated (or used) by the test apparatus 100 in the process of operation, calculation results, thresholds, reference values, parameters, and the like. Further, the storage unit 162 may supply the stored data to the request source in response to requests from each unit in the test apparatus 100 .

The fire sensor detection section 163 detects the fire sensor 10 from the image acquired by the image acquisition section 161 . The fire sensor detection unit 163 detects the fire sensor 10 by executing predetermined image processing. Also, the fire sensor detection unit 163 detects the relative position of the fire sensor 10 in the image captured by the imaging unit 150 . For example, the fire sensor detection unit 163 identifies the distance and direction from a predetermined area or range in the image captured by the imaging unit 150 to the fire sensor 10 .

Here, the predetermined position is, for example, the center of the image. Also, the predetermined range is, for example, an area inside a circle centered at the center of the image and having a predetermined radius. Also, the distance from the predetermined area or range in the image to the fire sensor 10 may be the distance on the image plane in the captured image. For example, the number of pixels present in the X and Y directions from the center of the captured image to the image of the fire detector 10 may be detected as the distance index. Note that the actual distance on the ceiling surface 12 corresponding to one pixel in the captured image may be measured in advance, and the fire sensor detecting section 163 may convert the actual distance corresponding to the number of detected pixels.

The drive signal generator 164 generates a control signal for driving the motor. The drive signal generation unit 164 generates a control signal so that the fire sensor 10 is positioned within a predetermined range of the image captured by the imaging unit 150 . The drive signal generator 164 generates, for example, a control signal for moving the housing 120 so that the distance from the predetermined area or range specified by the fire sensor detector 163 to the fire sensor 10 becomes smaller. do.

For example, consider a case where the fire sensor detection unit 163 identifies that the center of the fire sensor 10 is imaged at a position shifted by 200 pixels in the +X direction and 150 pixels in the -Y direction from the center of the image. In this case, the drive signal generator 164 generates the first control signal to move the housing 120 in the +X direction by a distance corresponding to 200 pixels. Further, the drive signal generator 164 generates a second control signal for moving the housing 120 in the -Y direction by a distance corresponding to 150 pixels.

The drive signal generation unit 164 calculates, for example, the magnitude of the force to be generated to move the housing 120 by a predetermined distance, the period for generating the force, etc. using a function calculated in advance, and the calculation result is Generate corresponding control signals. Further, the drive signal generation unit 164 uses a table specified in advance to determine the correspondence between the movement distance of the housing 120, the magnitude of the force generated for moving the housing 120, the period during which the force is generated, and the like. good too. In this case, it is desirable that the storage unit 162 stores the information of the table. Accordingly, the drive signal generation unit 164 can read the table information from the storage unit 162 and generate a control signal corresponding to the distance to move the housing 120 .

The drive signal generator 164 supplies the generated control signal to the motor drive circuit 220 . The drive signal generator 164 supplies, for example, the generated first control signal to the first motor drive circuit 220a and the generated second control signal to the second motor drive circuit 220b. Thereby, the control unit 160 controls the force generation unit 200 to generate forces in at least two different directions parallel to the ceiling surface when the opening 122 of the housing 120 is directed toward the ceiling surface. Let

Then, the control unit 160 adjusts the attitude of the housing 120 so that the fire sensor 10 is located within a predetermined range of the image captured by the imaging unit 150 . For example, the control unit 160 adjusts the attitude of the housing 120 each time the image capturing unit 150 captures an image of the fire sensor 10 . Note that the control unit 160 rotates the rotating disk 210 at a constant speed when the fire sensor 10 is positioned within a predetermined range in the image captured by the imaging unit 150 . In this manner, the control unit 160 controls the force generation unit 200 based on the image captured by the imaging unit 150 to change the posture of the housing 120 so that the opening 122 of the housing 120 faces the fire sensor 10 . can be adjusted.

The control unit 160 described above may be configured by a CPU or the like. For example, when a computer functions as the control unit 160, the storage unit 162 may store information such as an OS (Operating System) and programs that make the computer function. Further, the storage unit 162 may store various information including a database that is referred to when executing the program. For example, the computer functions as an image acquisition section 161 , a fire sensor detection section 163 and a drive signal generation section 164 by executing programs stored in the storage section 162 .

The storage unit 162 includes, for example, a ROM (Read Only Memory) storing various programs executed by a computer or the like, various tables, and the like, and a RAM (Random Access Memory) serving as a work area. The storage unit 162 may also include a large-capacity storage device such as a HDD (Hard Disk Drive) and/or an SSD (Solid State Drive).

As described above, the test apparatus 100 can adjust the attitude of the housing 120 based on the image captured by the imaging section 150 . According to the test apparatus 100 as described above, the user U holds the supporting portion 110 and moves the housing 120 to the vicinity of the fire sensor 10 to a position where the imaging portion 150 can image the fire sensor 10. Quickly adjust the position of the housing 120 to an appropriate position. Therefore, for example, even when inspecting the fire sensor 10 installed at a height exceeding 10 m, the user U can detect the fire without delicately manipulating the position of the housing 120 by holding the support part 110. An operational test of the device 10 can be easily performed.

In addition, when the fire detector 10 detects the occurrence of a fire, the fire sensor 10 informs the outside of the occurrence of the fire using communication or the like. Therefore, the test apparatus 100 can determine whether or not the fire sensor 10 has normally operated by further providing the operation detection section 230 . The operation detection unit 230 has, for example, a receiver that receives a transmission signal for notifying that the fire detector 10 has detected the occurrence of fire. For example, when the fire sensor 10 is activated in response to the generation of smoke or heat after the control unit 160 adjusts the posture of the housing 120, the operation detection unit 230 detects whether the fire sensor 10 is operating normally. Determine that it worked.

In addition, if the fire sensor 10 does not operate even if smoke or heat is generated after the control unit 160 adjusts the posture of the housing 120, the operation detection unit 230 detects whether the fire sensor 10 normally operates. It may be determined that it is not. Note that the control unit 160 transmits a control signal for stopping the occurrence of a simulated fire to the simulated fire generating unit 130 in response to the operation detecting unit 230 determining that the fire sensor has operated normally. may Thereby, the test apparatus 100 can quickly shift to the test operation of the next fire sensor 10 .

In addition, there is a fire sensor 10 that, when detecting the occurrence of a fire, emits an operation confirmation lamp to notify the occurrence of the fire. When testing the fire sensor 10 as described above, the test apparatus 100 may determine whether the fire sensor 10 operates normally based on the image captured by the imaging unit 150 . For example, the fire sensor detection unit 163 performs image analysis to determine whether or not the operation confirmation lamp of the detected fire sensor 10 is emitting light. Thereby, the control unit 160 can operate as the operation detection unit 230 .

Although the test apparatus 100 according to the present embodiment has been described as an example in which the force generation section 200 uses the reaction wheel to generate a force for adjusting the posture of the housing 120, the present invention is not limited to this. The force generation unit 200 may generate a force for adjusting the posture of the housing 120 using a gyroscopic effect. The force generating section 200 as described above will be described below.

<Second Configuration Example of Force Generation Unit 200>
FIG. 6 shows a second configuration example of the force generating section 200 according to this embodiment. FIG. 6A shows the appearance of the force generating section 200 of the second structural example, and FIG. 6B shows the internal structural example of the force generating section 200 of the second structural example. The force generating section 200 of the second configuration example includes a rotating disk 210, an actuator 240, a motor 212 that rotates the rotating disk 210, a motor drive circuit 220 that drives the motor, and an actuator drive circuit 250 that drives the actuator. have.

The rotating disc 210 of the force generating section 200 rotates with a plane substantially parallel to the opening plane of the opening 122 of the housing 120 as a plane of rotation. Actuator 240 changes the inclination of the rotating surface of rotating disk 210 . FIG. 6 shows an example in which the force generating section 200 has a first actuator 240a for generating force in the X-axis direction and a second actuator 240b for generating force in the Y-axis direction. An example of the direction of rotation of the rotating disk 210 is indicated by an arrow.

Also, the first actuator drive circuit 250a drives the first actuator 240a, and the second actuator drive circuit 250b drives the second actuator 240b. The first actuator 240a and the second actuator 240b apply force to the rotating disk 210 in the +Z direction or the -Z direction to tilt the rotating surface of the rotating disk 210. FIG.

In general, when no force is applied to the rotating body from the outside, the rotating body rotates while maintaining the rotation axis, and tends not to change its posture as the rotation speed increases. When a force is applied to the rotating shaft of the rotating body, a force is generated that tilts the rotating body in a direction orthogonal to the direction of the rotating shaft and the direction of the applied force (gyro effect).

FIG. 7 is a diagram for explaining such a gyro effect. For example, consider a rotating disk 210 that rotates around the origin with the XY plane as the plane of rotation. Then, as shown as the first direction in FIG. 7, a force is applied to the rotating disk 210 so as to tilt the rotation axis in the Y direction, and the rotating surface of the rotating disk 210 is tilted from the XY plane to the XY' plane. think. In this case, as shown as the second direction in FIG. 7, a force is generated in the X direction that tilts the rotating shaft in the X direction.

In this way, the rotation surface of the rotating disk 210 can be tilted, for example, by applying a force to the rotating disk 210 in the Z direction from one point on the Y axis. Therefore, the first actuator 240a is provided on the Y-axis when the rotation axis of the rotating disk 210 is set as the origin. Then, the first actuator 240a applies a force to the rotating disk 210 in the +Z direction or the -Z direction from one point on the Y axis, and tilts the rotation axis of the rotating disk 210 in the +Y direction or the -Y direction to rotate. Tilt the face. By driving the first actuator 240a in this way, the force generator 200 can generate a force in the -X direction or the +X direction.

Similarly, with respect to the rotating disk 210 rotating around the origin with the XY plane as the surface of rotation, the rotating disk 210 rotates in the Z direction from one point on the X axis so that the rotation axis is tilted in the X direction. When a force is applied, a force in the Y direction is generated that tilts the rotation axis in the Y direction. Therefore, the second actuator 240b is provided on the X-axis when the rotation axis of the rotating disk 210 is set as the origin. Then, the second actuator 240b applies a force to the rotating disk 210 in the +Z direction or the -Z direction from one point on the X axis, and tilts the rotation axis of the rotating disk 210 in the +X direction or the -X direction to rotate. Tilt the face. The force generator 200 can generate a force in the +Y direction or the -Y direction by driving the second actuator 240b in this way.

The larger the inclination angle of the rotating surface of the rotating disk 210 and the faster the rotating speed of the rotating disk 210, the greater the magnitude of the force generated by the force generating unit 200. The control unit 160 controls the actuator 240 of the force generating unit 200 described above to change the inclination of the rotation surface of the rotating disk 210, thereby changing the direction and magnitude of the force generated by the force generating unit 200. Adjust the posture of body 120 . Such a control unit 160 will be described below.

<Second Configuration Example of Control Unit 160>
FIG. 8 shows a second configuration example of the control unit 160 according to this embodiment. In the control section 160 of the second configuration example, the same reference numerals are assigned to the operations that are substantially the same as those of the control section 160 of the first configuration example shown in FIG. 5, and the description thereof is omitted. The control unit 160 of the second configuration example has an image acquisition unit 161 , a storage unit 162 , a fire sensor detection unit 163 and a drive signal generation unit 164 .

FIG. 8 shows, together with the control unit 160, a motor drive circuit 220 that drives the motor that rotates the rotating disk 210, a first actuator drive circuit 250a that drives the first actuator 240a, and a second actuator 240b that drives the second actuator 240b. Actuator drive circuit 250b and actuation sensing portion 230 are also shown.

The drive signal generator 164 of the second configuration example generates a control signal for driving the motor to rotate at a constant speed. The drive signal generator 164 supplies the generated control signal to the motor drive circuit 220 to rotate the rotating disk 210 at a predetermined constant angular velocity. Then, the drive signal generation section 164 generates a control signal for controlling the actuator 240 so that the fire sensor 10 is positioned within a predetermined range of the image captured by the imaging section 150 .

The drive signal generator 164 calculates, for example, the angle at which the rotating surface of the rotating disk 210 is tilted in order to move the housing 120 by a predetermined distance, using a previously calculated function or the like. Then, the drive signal generation unit 164 generates a control signal for causing the actuator 240 to tilt the rotating surface of the rotating disk 210 by the calculated angle.

Alternatively, the drive signal generator 164 may use a table that specifies in advance the correspondence between the moving distance of the housing 120 and the angle at which the rotating surface of the rotating disk 210 is tilted. In this case, the storage unit 162 stores the information of the table, and the driving signal generation unit 164 reads out the information of the table and generates a control signal corresponding to the distance by which the housing 120 is moved.

The drive signal generator 164 generates, for example, a first control signal that drives the first actuator 240a to move the housing 120 in the X direction. Then, the drive signal generator 164 supplies the generated first control signal to the first actuator drive circuit 250a. The drive signal generator 164 also generates a second control signal for driving the second actuator 240b to move the housing 120 in the Y direction. Then, the drive signal generator 164 supplies the generated second control signal to the second actuator drive circuit 250b.

Thereby, the control unit 160 adjusts the posture of the housing 120 so that the fire sensor 10 is positioned within a predetermined range of the image captured by the imaging unit 150 .

In this case, the second actuator 240b is provided inside the gimbal mechanism 260 on the outside, and generates a force in the X direction by moving the rotating shaft of the rotating disk 210 in the Y direction.

As described above, the force generation unit 200 of the third configuration example is parallel to the ceiling surface when the opening 122 of the housing 120 faces the ceiling surface, similar to the force generation unit 200 of the second configuration example. Moreover, forces can be generated in at least two different directions. Then, the control unit 160 controls the force generation unit 200 of the third configuration example in the same manner as the force generation unit 200 of the second configuration example so that the opening 122 of the housing 120 faces the fire sensor 10. The posture of the housing 120 can be adjusted.

As a result, the test apparatus 100 can adjust the posture of the housing 120 by generating force from the force generating section 200 based on the received control signal.

Also, the mobile terminal may receive a transmission signal for notifying that the fire detector 10 has detected a fire. In the case of the fire sensor 10 that notifies the occurrence of a fire by emitting an operation confirmation light, the mobile terminal analyzes the acquired image data to determine whether the operation confirmation lamp of the fire sensor 10 is emitting light. It may be determined whether Thereby, the user U can confirm the test result of the fire sensor 10 on the portable terminal at hand. Further, the user U may instruct the test apparatus 100 to start or stop the test from the portable terminal.
