The camera 4a is mounted. In addition, flow meter 2
If an electromagnetic flow meter 9 is used, there is no obstruction inside the measuring tube, so that there is no pressure loss and accurate nozzle pressure can be measured.
As shown in FIG. 8, the water discharge inspection device 27 is initially housed vertically in the robot 1 in a shortened state, as shown by a solid line, directly below.

When using the water discharge inspection device 27, the CPU 6
As shown by the dashed line, the cylinder 27a is extended to the design length, and the water discharge connection port 4 at the tip is inserted into the maintenance valve 17, as shown by the dashed line. At the time of insertion, it is movable left and right, up and down or back and forth at the rotation source part 27c of the water discharge inspection device 27 for fine adjustment of the alignment.
The CPU 6 operates a position and angle adjustment device (not shown) that also enables right and left swing or shaft rotation. The cylindrical body 27
The tip of a is flexible so that some angle error is absorbed. For example, as shown in FIG. 7, the water discharge connection port 4 is formed so as to be detachably attached to the maintenance valve 17 with one touch.

The inflow port 23 and the second outflow port 22 communicate with each other.

The water discharge connection port 4 is provided at the tip of the water discharge inspection device 27 and is attached to and detached from the second outlet 22. When the connection port 4 is inserted into the second outflow port 22, the valve body 19 is pushed up to switch the flow path, and the locking portion 4b of the slider 4c of the connection port 4 is engaged with the engagement groove 22a. Then, both are fixed. When the two are separated, the connection port 4,
That is, when the cylindrical body 27a of the water discharge inspection device 27 is rotated in a predetermined direction around the axis, the engaged state is released, and the connection port 4 is easily pulled out by pulling the connection port 4 toward the user. On the downstream side of the connection port 4,
A pressure sensor 28, a flow meter 29, and a water discharge nozzle 30 having the same specifications as the fire hydrant device are provided. The water discharge nozzle 30 is changed to an optimum one for each test target location.

As shown in FIG. 3, the positioning positioner 5 is a sensor of a photoelectric type or a magnetic type, for example, a light emitting device 5a for irradiating a bar code 14 provided at a design position of the fire hydrant box 10 with detection light, And a light receiver 5b that receives the reflected light from the bar code 14. Since the CPU 6 controls the position of the robot 1 based on the output of the positioner 5, the robot 1 can be accurately stopped at the design inspection position of the fire hydrant device.

The bar code 14 includes, as information, the manufacturer of the fire hydrant device, the article name, the model number, the serial number, the installation position information of the fire hydrant device S, the manufacturing date, the mounting position information of the bar code 14, and the like. I put it. Sheet 14P of bar code 14 to be attached to the front of fire hydrant box 10
May be horizontal (the bar in the barcode is a vertical line)
It is advisable to attach a vertically long one (the bar constituting the barcode is a vertical line). By adhering the vertically long sheet, the positioning positioner 5 that scans while moving horizontally does not have a risk of failing to detect due to a shift in the vertical position, and can reliably detect the presence of an object to be inspected. The bar code 14 may be of a magnetic type instead of the reflective type.

The CPU 6 of the computer CP is a control device of the robot 1, and controls the traveling and the manipulator 2
Control, facing control with the fire hydrant box 10, camera work control of the ITV camera 3, control of the water discharge inspection device 27, control of the illuminator, control of the fall prevention rod 36, etc., and the load sensor 13 and the pressure sensor 28. , The flow meter 29, the ITV camera 3, the positioning positioner 5, and the stroke measuring device 39 of the manipulator 2. Also, CPU6
Executes a predetermined maintenance inspection program stored in the storage unit 8, performs an inspection operation and a measurement operation, and automatically determines whether or not the fire hydrant device is normal based on the measurement result and information processing. Controlled.

When the operator remotely instructs to execute the inspection work of all or one fire hydrant device S or one inspection item in the tunnel Tn, or a part of the operation of the inspection item, Upon receiving this instruction, the CPU 6 determines the information necessary to execute the instruction, that is, the situation around the robot 1 by the above-described control and information processing, such as camera work control and video information processing. Then, the CPU 6 may automatically control the robot 1 to move autonomously.

In the case of the automatic control described above, in the case of the remote control, for example, when the operator operates an operation rod (not shown), for example, a continuous operation instruction signal is transmitted, and the received operation instruction signal is transmitted. The CPU 6 may simply cause the robot 1 to execute the same operation without determining the situation.

The traveling wheels 7 are driving wheels for moving the main body 20 of the robot 1, and move the maintenance / inspection robot 1 in a predetermined direction using a battery, an external power supply, or an engine. The traveling wheel 7 can be moved in any direction by a mechanism not shown. The support wheel 35 is attached to the main body 20.
Road 3 provided on the support wheel leg 20a projecting from the back of the vehicle.
2, when the robot 1 presses the door and closes by pressing the door, the robot 1
I try not to fall to the side. Also, the support wheel leg 20
“a” can be expanded and contracted in accordance with the height of the monitoring passage 33 and its height can be changed, so that it can be handled without a step.

The guide wheel 34 is supported by the support wheel leg 20a.
The leg 2 is provided on the inside of the
0a is in contact with the monitoring passage 33 so as not to be damaged. The support wheel 35 and the support wheel leg 20a may not be provided.

The fire hydrant box 10 has two doors, ie, a forward tilting door 10a and a fire extinguisher door 10b. The fire hydrant box 10 is buried in the side wall 31 of the tunnel Tn, and a monitoring passage 33 is provided between the fire hydrant box 10 and the roadway 32.

Next, the procedure of the operation and inspection method of the embodiment of the maintenance and inspection robot 1 will be described. As shown in FIG. 2, the robot 1 is placed on the monitoring passage 33 of the tunnel Tn, the support wheel 35 is attached to the roadway 32, and preparation for maintenance and inspection is performed (S1).

At this time, the fall prevention rod 36 is attached to the fire hydrant box 10.
It protrudes to the extent that it can be approached to the upper part of. This stick 36
Expands and contracts under the control of the CPU 6 as needed, such as when the door 10a is opened. The rod 36 is provided with the forward tilting door 10a and the fire extinguisher door 1
0b, two on the left and right sides to face the frame portion of the fire hydrant box 10 excluding the indicator light and the like. In addition, the fall prevention bar 36
May be selected as needed.

For example, when an inspection start signal is sent from the control panel (not shown) in the disaster prevention center to the CPU 6 via the antenna 37, the traveling wheels 7 rotate and the robot 1 starts traveling along the monitoring passage 33 ( S2). At this time, the running is guided by a tracer (not shown) that keeps a certain distance from the edge of the monitoring passage 33, and the robot 1 does not come off the edge of the monitoring passage 33. This tracer may be carried by the guide wheel 34.

At this time, the positioning positioner 5 is also operating, and when the robot 1 reaches the position of the fire hydrant box 10 to be inspected, the light of the light emitter 5a is reflected by the bar code 14 and enters the light receiver 5b ( S3). Then, the receiver 5
b sends a detection signal to the CPU 6, so that the CPU
6 stops driving of the traveling wheel 7. Therefore, the robot 1 accurately stops at the design position (S4).

At this time, the relative position and direction of the robot 1 with respect to the fire hydrant device S are determined by the bar code 1 in the running direction.
4 and the positioning positioner 5, the facing position and the inclination angle (facing horizontal angle) with the fire hydrant device S can be adjusted by extending the two fall prevention rods 36 to the facing fire hydrant device S. It can be obtained by contacting.

A contact sensor (not shown) is provided at the tip of each of the two falling bars 36, and a stroke sensor (not shown) that can detect the extension dimension is provided at the arm of the falling bar 36, so as to extend and contract. Since the corresponding stroke dimensions are output, the distance and the inclination angle to the facing fire hydrant device S can be known from the measured values by the CPU 6.
From the measured values, the CPU 6 may control the traveling wheels 7 to make the robot 1 and the fire hydrant device S parallel to obtain a predetermined relative positional relationship, that is, to make them face each other.

The positioning positioner 5 has a bar code 14
Is read and transmitted to the CPU 6. Based on this information, the CPU 6 confirms whether or not the fire hydrant device S is to be inspected and whether or not it is directly facing the fire hydrant device S (S5).

After confirming the above, the CPU 6 instructs the start of inspection. First, rotate the ITV camera 3,
Turn on the illuminator if necessary, and set the fire hydrant box 10
, And sends the photographed image to the CPU 6. This appearance check mainly checks the appearance for damage, deformation, corrosion, lighting state of the indicator lamp, and the like (S6). The appearance check was performed by observing, for example, an image of the individual fire hydrant device S when it was first photographed with the robot 1 or an image of the fire hydrant device S in a new state, that is, a reference image in a predetermined state. The image of the fire hydrant device S taken in the inspection as the situation is compared by, for example, image processing.

That is, the image of the fire hydrant device taken during the inspection is converted into, for example, an appearance image viewed from the same distance and angle as the reference image and an image having the same average brightness, and these are compared to determine a difference. Thus, the CPU 6 determines whether the external appearance is damaged or deformed. If there is no difference exceeding a predetermined value, the CPU 6 determines that the appearance check is normal.

For example, the lighting state of the indicator lamp is assumed to be normal if it is turned off as the reference image if it is brighter than the reference image to a certain extent. Light may be recognized.

Regarding corrosion, after cleaning with a cleaning device (not shown), the images are compared so that they can be distinguished from dirt. This judgment (evaluation) is stored in the storage unit 8 and sent to the control panel of the disaster prevention center. The captured image may be sent to the disaster prevention center together with the data of the barcode 14.

Next, an image of the front of the fire hydrant device S taken by the ITV camera 3 under the control of the CPU 6 and the fall-down stick 36
The CPU 6 recognizes the position of the handle 15 of the forward tilting door 10a, which is a fire hydrant door, from the measured distance from the stroke sensor. Then, under the control of the CPU 6, the robot 1 extends the manipulator 2 as shown in FIG.
5, the load sensor 13 attached to the inside of the hook 2a is engaged with the back surface of the unlocking portion 15a, and is slowly pulled in the direction of arrow A12 while maintaining the engaged state.

At this time, the robot 1 is
Although it is pulled to the 0 side, it does not fall because the fall-prevention bar 36 comes into contact with the frame portion of the box 10. Then, unlocking unit 1
5a is pulled, and the latch unit 15 linked to the unlocking unit 15a
b is disengaged from a lock hole (not shown) of the fire hydrant box 10, and as shown in FIG.
The door opens (S7).

The fire hydrant box 10 is provided with a closing limit switch (not shown) between the closed sloping front door 10a and the closed sloping door 10a. At the start, the closing limit switch is turned off, and unlocking and locking of the latch 15b are recognized by the closing limit switch. Further, the fire hydrant box 10 is provided with a fully open limit switch (not shown) between the hydrant box 10 and the fully opened front leaning door 10a, and is turned on only when the forward leaning door 10a is fully opened.

The on / off state of the closing limit switch and the fully opening limit switch is determined by the fire hydrant device S, respectively.
The information may be displayed on display means such as LEDs (not shown) provided on the front surface, and the display status of these display means may be captured by the ITV camera 3 so that the CPU 6 recognizes whether the front tilted door 10a is fully opened or fully closed. .

During the period from when the load sensor 13 starts engaging with the unlocking portion 15a to when the latch portion 15b comes off,
The load sensor 13 provided on the manipulator 2 measures the load, and the measurement result is sent to the CPU 6. The CPU 6 compares the load required for operation of the unlocking portion 15a of the forward tilting door 10a, that is, the maximum load of the measured value, with the allowable range of the reference load from the measured value to determine whether the load is normal. (S8). This judgment (evaluation) is stored in the storage unit 8 and sent to the control panel of the disaster prevention center.

In the above description, the load sensor 13 is mounted inside the hook 2a at the tip of the manipulator 2.
A load sensor may be attached to the arm of the manipulator 2 so as to capture the traction of the arm in the axial direction. In this case, when opening the front tilting door 10a, the manipulator 2 is extended and inserted into the handle 15, and the inside of the hook 2a is engaged with the back surface of the unlocking portion 15a. At this time, the measured value of the load sensor of the arm from immediately before the engagement to the completion of the unlocking is stored with time, or the measured value immediately before the engagement and the maximum load value until the unlocking is completed is stored. The completion of unlocking is determined by capturing the display status of the LED or the like with the ITV camera 3 and recognizing that the closing limit switch is off by the CPU 6.

In the case of the fire hydrant device S not provided with the closing limit switch, the recognition of the completion of unlocking is performed by, for example, IT
The V-camera 3 records the edges and corners of the forward-sloping door 10a in close-up with the time, and determines the unlocking completion at the moment when the forward-sloping door 10a starts to be opened by the image processing. The travel distance of the hook 2a of the manipulator 2 from the start of engagement of the door to the handle 15 to the completion of unlocking is measured by the stroke measuring device 39, and the measured value is compared with this as a reference, and the handle 15 is pulled. However, the time when the strokes match may be determined to be unlocking completion.

Alternatively, another manipulator (not shown) or the like having a load sensor, a touch sensor, or the like at the tip thereof may be used.
This load sensor etc. is in contact with the front of the fire hydrant door (or placed at the position of the fire hydrant door when unlocked), and when this load sensor etc. catches the load, the manipulator etc. is retracted and the time is unlocked at the same time. It may be determined to be completed.

After that, the operation status of the forward tilting door 10a is I
It is photographed by the TV camera 3, is processed with a moving image, and whether or not the operating conditions such as the opening speed and the time required for the opening of the front tilting door 10a are normal is stored in a state where the components inside the front tilting door 10a are normal. Whether or not, harmful damage,
It is observed and checked whether there is deformation, corrosion, or the like (S9).

As described above, the manipulator 2 is engaged with the forward-sliding door 10a and the photographing is started when the load sensor 13 starts detecting the load.
0a, the movement of the upper edge is captured, and a predetermined opening degree (for example, 30 degrees, 45 degrees, 60 degrees, 9 degrees) is obtained immediately after unlocking.
Time, etc.) or "opening speed"
Is calculated, and this data is compared with a predetermined reference opening time or opening speed to determine whether this data is within the allowable range of each reference value, for example, a range of 1/4 to 2 times the reference value. Judge.

For example, first, an image when the fire hydrant door 10a of the normal fire hydrant apparatus S is opened by 30 degrees and the required time are stored as references, and at the time of inspection, the opening operation of the fire hydrant door 10a is stored as a reference. It is photographed from the same camera viewpoint, and when the photographed image coincides with the reference image, the required time is stored as being opened by 30 degrees, and this is compared with the reference by the CPU 6 to determine whether the image is normal or not. May be determined.

The time from when the closing limit switch is turned off to when the fully open limit switch is turned on is determined as "time required for opening". "Opening speed" is forward leaning door 1
The movement of the side edge where the rotation of 0a can be seen is captured by image processing,
The angular velocity may be calculated. If there is no full-open limit switch, if the door opening operation stop angle deviates from the angle (for example, 85 to 95 degrees) considered to be fully open in the image processing, it is determined that the full-opening is abnormal. Check the opening speed etc. when it is too slow or too fast.

In the above, as the determining means for determining whether or not the operation state of the front tilting door 10a is normal, the stored image is subjected to image processing so as to be compared with the reference image, and is compared with the reference image. The CPU 6 is used to determine whether or not this is the case. In the above description, the required time from immediately after unlocking to the full opening is dealt with. However, it may be determined whether or not the required time from the engagement of the handle to the full opening after unlocking is normal.

For example, when it is necessary to open the fire hydrant door after the door is unlocked and before the door is fully opened, the operating state of the door of the fire hydrant apparatus is determined by the operation from the engagement of the handle of the fire hydrant door through the unlocking to the fully opened state. A temporal change in the door opening load may be captured. In this case, the load is measured by the load sensor 13 of the manipulator 2, but when the fire hydrant door is of a rotating type, the handle of the fire hydrant door is pulled before a predetermined opening degree (for example, 45 degrees), and thereafter, it is not shown. The rim of the fire hydrant door may be pushed open via the second load sensor by switching to the second manipulator.

The measured values of the two load sensors are stored in the storage unit 8
Remember. The CPU 6 (judgment means) judges whether or not this operating condition is normal by comparing the stored maximum value of the measured value (force required for opening) with a reference value. Regarding the above, the judgment is basically made by executing the same as the above-mentioned appearance check. That is, movable components (hoses, nozzles, hose reels, etc.) provided inside the door are excluded from the judgment by the image processing, and the other parts are compared with the reference screen by a method of appearance check. Note that the open / close lever is compared based on the image at the fixed position (closed).

Further, a screen excluding moving components (hose, nozzle, etc.) is used as a reference screen to be compared, and this screen is compared with an image-processed screen, and the screen of the difference is moved to the position of the moving component. When the CPU 6 recognizes a characteristic such as an average color of the component, the CPU 6 may determine that the moving component exists. For example, for a black rubber hose, if it is recognized that a black part exists in a certain area at the center position of the hose reel,
The CPU 6 may determine that a hose reel is present.

If the image is determined to be "abnormal", the image is sent to a disaster prevention center or the like together with the fire hydrant device number to urge the user to take action. In addition, the image is stored and the inspection manager later checks the corresponding evaluation item by looking at the image, or
Make corrections possible.

In photographing with the ITV camera 3, the operation and the appearance of the inspection object can be better determined.
By mounting the illuminator (not shown) away from the ITV camera 3 and turning on only one white light as close as possible to a point light source, the shadow of the inspection object can be clearly displayed. In addition, when observing the inside of the inspection object, the illuminator moves to a predetermined position for illuminating the inside so that the inside can be seen clearly. Note that the number of illuminators can be selected as needed.

Next, as shown in FIG. 8, the robot 1 faces the fire hydrant box 10 with the bar code 14 or the like as shown in FIG. Design position and face-to-face design angle (zero degrees, ie, parallel state in this embodiment)
When the water discharge inspection device 27 is activated and the cylindrical body 27a rises to, for example, a design angle, the position of the water discharge connection port 4 on the left and right (running direction) and the depression angle are determined by the fire hydrant device. Outflow port 22 of maintenance valve 17
And the right and left positions and the elevation angle may coincide with each other.

Therefore, the robot 1 is provided with a water discharge inspection device 2
7 is extended and inserted into the second outlet 22 of the maintenance valve 17 (S10). Then, the valve element 19
Is pressed by the water discharge connection port 4 and pressed against the first valve seat 26, so that the first outlet 21 is closed, and the second outlet 22 and the inlet 23 communicate with each other.

Since the small ITV camera 4a is provided at the top of the cylinder near the water discharge connection port 4, the position of the connection with the maintenance valve 17 can be easily adjusted by the CPU 6. As described above, when the water discharge inspection device 27 and the maintenance valve are connected, the water discharge channel 38 is formed. If the pump has not been started yet, the button such as the transmitter on the front of the fire hydrant box is pushed by the manipulator 2 to start the pump. Once done, the water discharge test is ready. The pump stop may be operated by a pump control panel in a disaster prevention center or the like after all the fire hydrant devices S in the tunnel Tn have been inspected.

The robot 1 moves the manipulator 2, grasps the opening / closing lever 12 and pulls it forward (S11), and opens the fire hydrant valve 11. At this time, the load sensor 13 of the manipulator 2 measures the operation load required to open the fire hydrant valve 11 via the opening / closing lever 12 (S12), and
A stroke measuring device 39 provided for the pressure sensor 28 measures the stroke of the opening / closing lever 12 and provides a pressure sensor 28
Measures the water discharge pressure due to the opening of the hydrant valve 11, the flow meter 29 measures the water discharge flow rate, and
Send to U6.

The CPU 6 controls the open / close lever 12
Does the stroke correspond to the full opening of the hydrant valve 11?
From the measured value, the maximum value of the operating load (excluding the load data at the time of full opening stroke) is compared with the reference value, whether it is normal or not, the water discharge pressure and the water discharge flow are measured after the stable flow after a predetermined time elapses The values are compared with the design values to determine whether they are normal or not, and are stored in the storage unit 8 (S13) and sent to the control panel of the disaster prevention center.

Next, a recovery operation is performed in a manner reverse to that described above (S14). That is, the opening and closing lever 1 is controlled by the manipulator 2.
2, the fire hydrant valve 11 is closed, the water discharge connection port 4 is removed from the maintenance valve 17 and returned to the original position, and the forward tilting door 10a is rotated by the manipulator 2 in the closing direction to be closed.

When the opening / closing lever 12 is gripped by the manipulator 2 and pressed, a load sensor (not shown) is provided on a surface which comes into contact with the hook portion 2a of the manipulator 2 when pressed.
The CPU 6 determines whether or not the maximum value of the load is normal and the stroke of the opening / closing lever 12 with a stroke measuring device 39 provided in the manipulator 2 and whether or not the hydrant valve 11 is fully opened.

Note that the stroke of the opening / closing lever 12 is IT
It is also possible to determine whether or not the opening / closing lever 12 is normally in the fully open or fully closed state by taking an image with the V camera 3 and performing image processing in the CPU 6 and comparing it with the reference screen.

In order to confirm whether the fire hydrant valve 11 is fully closed due to the stoppage of the opening / closing lever 12, for example, a nozzle valve (not shown) may be provided between the pressure sensor 28 and the water discharge nozzle 30. . In this case, the nozzle valve is closed, the opening / closing lever 12 is closed, the space between the fire hydrant valve 11 and the nozzle valve is filled with water, and the pressure relief valve (not shown) provided between the nozzles is opened and closed once. To avoid pressure. Then, after waiting for a predetermined time, if the pressure sensor 28 detects an increase in pressure, the hydrant valve is not fully closed. Here, as described above, the nozzle valve, the opening / closing lever 12 and the pressure relief valve may be operated again to release the pressure and stand by. If pressure increase is detected again in the same manner as above, the CPU 6 determines that the fire hydrant valve is not fully closed at this time, stores it in the storage unit 8, and sends it to the control panel of the disaster prevention center. As shown in FIG.
When the front door 10a is closed, the front tilting door 10a is supported by the manipulator 2, and the front tilting door 10a is lifted up from the horizontal state shown by the solid line and raised to the vertical state shown by the chain line.

For this purpose, for example, three rectangular destination plates are formed in the order of an upper plate 9a, a middle plate 9b, and an outer plate 9c in a substantially Z-shaped cross section (a pair of complex angles is 90 degrees, for example, 135 degrees). On the upper surface of the upper plate 9a, a connecting portion 9d that protrudes from the tip of the manipulator 2 is protruded, and the holding portion 9 including the connecting portion 9d and the three destination plates 9a, 9b, and 9c is provided. Constitute.

It is to be noted that a required moment can be given to the connecting portion 9d from the manipulator 2. Further, a load sensor (not shown) is provided on a surface of the middle plate 9b and the outer plate 9c on the upper plate 9a side. Here, the upper plate 9a is applied to the end opposite to the rotation axis 10p of the front leaning door 10a, that is, to the open end (the front side edge in the fully opened state).
The middle plate 9b is applied to the front surface (the lower surface in the fully opened state) of the.

The manipulator 2 lifts the upper edge of the front leaning door 10a while holding the moment at the connecting part 9d so that the two destination plates 9a and 9b do not separate from the forward leaning door 10a. . The load of the door 10a is
It is applied to a load sensor (not shown) of the middle plate 9b. Immediately before closing, the latch portion provided on the upper edge of the forward tilting door 10a is locked in the latch hole of the fire hydrant box 10.
By giving an upward moment to the grip portion 9 and raising the upper plate 9a and the middle plate 9b toward the user, the grip portion 9 is rotated upward,
The outer plate 9c is applied to the front surface of the front tilting door 10a and pushed.

At this time, the resistance of the door 10a is
Since the load is measured by a load sensor (not shown) c, the load can be known. The fully open limit switch is turned off when the front leaning door 10a is released from full open, and the close limit switch is turned on when closed. For example, the latch is completely closed from full open to fully closed, or closed until just before locking. The closing operation state includes a change in the closing load (from lifting to pushing) of the front tilting door 10a, and the CPU 6 determines whether the maximum load is normal.

The evaluation of the closing operation of the forward tilting door 10a is as follows.
Instead of measuring the closing load of the door, the determination may be made based on the time between the activation of the two switches. In this case, the closing force is adjusted so that the closing speed does not exceed a predetermined value, for example, by closing with a manipulator at a constant speed so that the closing force does not unnecessarily vigorously close, and the front tilting door 10a is closed. The time when the fully open limit switch is turned off when leaving the fully open state and the time when the close limit switch is turned on when closed are stored, and the CPU 6 determines whether or not the difference is normal. This judgment (evaluation) is stored in the storage unit 8 and sent to the control panel of the disaster prevention center.

Next, maintenance and inspection of the fire extinguisher are performed. The manipulator 2 is extended and locked to the handle 51 of the fire extinguisher door 10b, and is pulled forward to open the door (S15). At this time, the load sensor 13 provided on the manipulator 2 measures the load, and the measurement result is sent to the CPU 6. After comparing the measured value with the reference value, the CPU 6 determines whether the load required for the operation of opening the fire extinguisher door 10b is normal (S16). This judgment (evaluation) is stored in the storage unit 8 and sent to the control panel of the disaster prevention center.

The operation and the internal state of the fire extinguisher door 10b are photographed by the ITV camera 3 and processed as a moving image, and whether the operation state such as the opening speed of the door 10b, the time required for opening, etc. is normal is harmful. Whether there is any damage, deformation, corrosion, whether the fire extinguisher in the fire extinguisher door 10b is normally stored, and if the fire extinguisher is equipped with a pressure gauge, whether it indicates a normal pressure. Is checked.

If necessary, extend the manipulator 2 and raise the fire extinguisher, and check whether the weight is normal or not.
Is checked (S17). The tip of the manipulator 2 that lifts the fire extinguisher is, for example, in the form of an L-shaped hook having a load sensor inside, and is engaged with the handle of the fire extinguisher so that the load sensor contacts the handle. When the fire extinguisher is lifted as it is, the load sensor receives the weight of the fire extinguisher from the handle and measures the load.

In the above, the ITV camera 3 zooms in, shoots the pointer of the pressure gauge of the fire extinguisher, processes the image, and determines whether or not it is normal. This judgment (evaluation) is stored in the storage unit 8 and sent to the control panel of the disaster prevention center.

Next, a recovery operation is performed in a manner reverse to that described above (S18). That is, the fire extinguisher door 10 is controlled by the manipulator 2.
b is closed in the closing direction.

The maintenance and inspection of the fire hydrant device S has been completed as described above.
6 moves the robot 1 to the next fire hydrant device S (S19). The maintenance and inspection robot 1 is provided with a range finder, for example, a laser type range finder.
Measure some distances between the hydrant box 10 and
It is also possible to determine whether the box 10 is tilted more than necessary with respect to the robot 1 or the tilt with respect to the monitoring passage 33 or the vertical.

When checking the vertical inclination of the fire hydrant box 10, the robot 1 is provided with a vertical sensor.
The inclination is measured based on this. Further, this range finder can be used as a facing means. If the robot 1 is observed to have a tilt angle exceeding the allowable range with respect to the hydrant box 10, the CPU 6 determines the direction and height of the traveling wheels 7 so that the robot 1 faces the hydrant box 10. To change the tilt angle.

If an abnormality is found in the above inspection, the abnormal item is recorded or reported to the disaster prevention center or an inspection result sheet is printed out and attached in a plastic bag in front of the fire hydrant device, and repaired. Is provided as information when performing. In the above inspection, abnormal cases were considered abnormal, but among abnormalities, cases where the traction load when opening the door was 30 kg or more or the level was almost unusable, such as not opening, were regarded as “failure” and below. If it can be used, the rank of the determination result may be classified as “unsuitable” or the like, so that the urgency of the response may be known.

In the above embodiment, the robot is started by a remote command, and the maintenance and inspection robot 1 performs the maintenance and inspection work of one hydrant apparatus S or the maintenance and inspection work of all the fire hydrant apparatuses S in the tunnel Tn according to the program. In other words, in order to execute a predetermined operation without obtaining human judgment, the CPU 6 obtains necessary information from various sensors and devices in a situation around the robot 1 and prepares the robot 1 for inspection preparation and the like. This example shows an example of automatic control in which a predetermined operation is autonomously completed, such as making a judgment when moving, and evaluating and judging a measurement operation and an inspection result.

However, the starting method differs from the above method.
For example, it may be activated by an activation switch (not shown) of the robot body 20. Further, after checking all the fire hydrant devices S in the tunnel following the activation, the vehicle may travel and return as it is, stop at a predetermined position, and automatically turn off the switch. In addition, a program may be set up so that this inspection is automatically performed periodically when the day comes.

Further, as described above, the maintenance and inspection work of one fire hydrant device S or all the fire hydrant devices S in the tunnel Tn is not performed by one instruction, but is instructed by one instruction from the control panel, for example. The maintenance and inspection of only one inspection item may be performed by automatic control. For example, when an instruction is given to perform a predetermined operation, which is one check item of opening a fire hydrant door, the robot 1 is controlled based on the instruction.
Obtain information from various sensors and devices about the surrounding situation, open the door autonomously, and determine whether the load and required time are normal based on the information obtained at the time of opening the door, such as the load and required time. Automatic control may be performed such that the robot 1 completes a predetermined operation such as judging whether or not the operation is not necessary.

Further, one operation of one inspection item may be performed by automatic control. For example, according to an instruction from the operator, a predetermined operation of one of the inspection items, for example, an operation of “engaging the manipulator 2 with the handle 15 of the hydrant door” is selected and instructed by the control panel, for example. In this case, the CPU 6 executes this instruction by autonomous control (automatic control) while recognizing the surrounding situation with the ITV camera 3 and various sensors.

For example, first, the CPU 6 knows the position and the structure of the handle 15 from the model number of the fire hydrant device S obtained from the bar code 14, selects the one whose tip part of the manipulator 2 fits the handle 15, and selects the ITV camera 3 The position of the handle 15 is recognized from the stroke sensor of the fall prevention bar 36 and the image, and the hook 2a at the tip of the manipulator 2 is extended and inserted into the recess of the handle 15, The hook portion 2a is moved upward and forward by a predetermined distance, and the load sensor 13 provided on the hook portion 2a is provided on the back surface of the unlocking portion 15a.
Comes in contact with each other, stops when the contact is detected, and returns a signal indicating completion of the specified operation.

In the above, the case of the automatic control of the robot 1 has been described, but the case of the remote control will be described below. An operator who is away from the robot 1, for example, at a control panel, for example, operates the manipulator 2 of the robot 1.
When the tip of the manipulator 2 is moved from various sensors and devices for recognizing the situation around the robot 1 while viewing information for operating the robot 1, for example, video information from the ITV camera 3, the tip of the manipulator 2 is moved. By operating, for example, an operation rod (not shown) on the control panel side made to move in the same manner as the operation movement, the operator determines whether the manipulator 2 does not collide with something, The remote control of simply executing the operation of the instruction may be performed. Here, an identification signal may be sent to make the CPU 6 recognize the difference between the instruction of the remote control and the instruction of the automatic control.

Further, for example, maintenance and inspection of one inspection item may be alternately executed by remote control and automatic control. For example, when the operator at the control panel selects an inspection item to open the fire hydrant door, for example, the door 10a
The operator engages the manipulator 2 with the handle 15 by remote control using an operation rod while watching an image from the ITV camera 3 through a receiver (not shown). The CPU 6 fully opens the door 10a with the manipulator 2 by selecting and instructing "starting of the fire hydrant door" in "opening inspection of the hydrant door", and the pass / fail judgment of the opening load measurement and the opening time measurement and the inspection. The control may be executed by automatic control including the steps up to and including the steps described above.

In the above description, the control device CP of the robot 1
Although U6 is provided in the robot 1, it may be provided outside the robot 1, for example, in a control panel.
