JP5524298B2 - Wind warning system - Google Patents

Description

The present invention relates to a technology to alert the strength of the wind and, more particularly, to a wind alarm systems that alert that the wind to a degree dangerous to the work, such as in high places has become stronger.

  When working at high altitude, wind strength becomes a problem. This is because work in strong winds is dangerous. Thus, various inventions have been made in which wind speed is measured and notified.

  Patent Document 1 describes a wind alarm device that generates power using the rotational force of a windmill and thereby turns on an LED to display a wind alarm. When the wind alarm device detects a wind speed of a certain speed or higher, the LED is turned on to light the letters “strong wind”. At this time, the LED lighting interval is varied according to the wind speed. When the wind speed is relatively slow, the lighting interval is lengthened, and when the wind speed is relatively fast, the lighting interval is shortened.

  Patent Document 2 describes an anemometer and a wind speed measuring method that can quantitatively grasp a wind speed value with a simple configuration without converting wind power into rotational force. It also describes outputting alarm information when the wind speed value exceeds a predetermined warning value, and sounding an alarm buzzer and lighting an alarm device according to the alarm information.

  Patent Document 3 describes a wind speed prediction device that obtains a predicted wind speed at a work place having a predetermined height from the wind speed at a ground position. The average wind speed at the work place is calculated from the predicted wind speed, and it is judged whether the wind speed that is considered dangerous is exceeded. If it exceeds, a buzzer will sound.

  Patent Document 4 describes a wind direction and wind speed display system that measures wind direction and wind speed data and wirelessly transmits the data to a terminal device. The terminal device displays the wind direction data mark with different sizes depending on the wind speed data. When the wind speed data exceeds a preset threshold, the wind direction data mark is turned on.

The wind alarm device of Patent Document 1 displays a strong wind warning on the display unit when a wind speed of a certain speed or higher is detected. Therefore, it is assumed that the display unit is used in a place where it can be visually recognized. In this regard, when considering use in a facility with a large area such as a power plant and a complex of buildings and equipment, it is expected that the display on the display unit cannot be seen in many places. In this case, the display of the attention to strong winds will not make sense.
In this regard, if the method of sounding an alarm buzzer described in Patent Document 2 and Patent Document 3 is adopted, information can be widely disseminated even in facilities such as power plants. However, it is difficult to distinguish whether the alarm buzzer sound is information that prompts attention to strong winds or other information. In addition, depending on the wind direction, it is expected that an area where the sound of the alarm buzzer is difficult to hear will be generated.
Patent Document 4 employs a more aggressive information transmission method using data processing technology. However, high-tech devices and systems that use data processing technology tend to become obsolete, so there is a possibility that the actual lifetime will be shortened. For example, a device such as a terminal device disclosed in Patent Document 4 is frequently subjected to model change, software update, and the like, and an increase in costs and the like occurs each time.

  The present invention has been made in view of the above points, and it can be seen from various places that the wind speed has reached a certain level or more even in a facility having a large area such as a power plant and a complex of buildings and equipment. The purpose is to be understood.

The wind alarm system of the present invention includes a support unit that supports the flag so as to be movable up and down, a motor that drives the flag lifting mechanism to raise and lower the flag, an anemometer that measures the wind speed and outputs a measurement value, First alarm means for driving the motor to raise the flag when the measured value of the anemometer reaches a prescribed wind speed region, and having a function of wirelessly transmitting the measured value of the anemometer A wind alarm device, and a portable terminal that receives the measured value of the anemometer transmitted wirelessly and issues an alarm when the measured value reaches a specified wind speed region, the portable terminal wirelessly received The above problem is solved by multiplying the measured value of the anemometer by a coefficient corresponding to the height of the work place to determine whether or not the prescribed wind speed region has been reached .

[First Embodiment]
A first embodiment will be described with reference to FIGS.
This embodiment is an embodiment of a wind alarm device.

As shown in FIG. 1, the wind warning device 11 is installed on the ground surface G. The wind alarm device 11 is provided with a pole 13 standing on a housing-like base body 12. A flag 14 is attached to the pole 13 so as to be movable up and down. On the flag 14, a character “Attention to strong wind” is drawn. The pole 13 is further positioned at the top thereof, and an anemometer 15, an alarm sound generator 16, and an alarm light generator 17 are attached thereto. In order from the top, the alarm light generator 17, the alarm sound generator 16, and the anemometer 15 are arranged.
The anemometer 15 has a structure in which a pair of wind receiving portions 52 are fixed to the side portion of a rotating body 51 that is rotatably attached to the pole 13. The rotating body 51 rotates when the wind receiving portion 52 receives wind. The rotation of the rotating body 51 is detected by a built-in sensor (not shown). The anemometer 15 calculates the rotation speed based on the signal obtained by detecting the rotation of the rotating body 51, calculates the speed from the calculated rotation speed, and outputs the calculated speed.
The alarm sound generator 16 is a device that includes a speaker 71 and an acoustic circuit 103 (see FIG. 3), and drives the speaker 71 by the acoustic circuit 103 to generate an alarm sound.
The warning light generator 17 is a device that incorporates a warning lamp 72 and a lighting circuit 104 (see FIG. 3) and lights the warning lamp 72 by the lighting circuit 104. The lighting of the alarm lamp 72 may be not only continuous lighting but also blinking.

As shown in FIG. 2, the flag 14 can be raised and lowered by an elevating mechanism 31. The elevating mechanism 31 is a belt winding mechanism that is built in the pole 13 and has a belt 32 wound around a pair of pulleys P. The pulley P located below is rotated by being driven by a motor 34 (see FIG. 3) via a speed reduction mechanism (not shown). As a result, the belt 32 rotates between the pair of pulleys P. Therefore, the stay 33 is fixed to a part of the belt 32, and the flag 14 is attached to the stay 33 so that the flag 14 is moved up and down. The lower pulley, the speed reduction mechanism, and the motor 34 are built in the base 12.
The elevating mechanism 31 has a built-in position sensor 35. The position sensor 35 detects a mark (not shown) attached to the outer peripheral surface of the belt 32. This is because the height position of the flag 14 is determined by the control unit 101 (see FIG. 3) described later. The height position of the flag 14 can be roughly determined by two methods. One is a technique in which the marks attached to the belt 32 are all different and unique shapes. If the position sensor 35 detects a certain mark, the height position of the flag 14 at that time is uniquely obtained. The other is a method of counting marks attached to the belt 32. The height position of the flag 14 can be obtained from the rotation direction of the belt 32 and the count number of the mark.

  As shown in FIG. 3, the wind alarm device 11 includes a control unit 101 that executes a predetermined sequence to control each unit. The control unit 101 is, for example, a sequencer. The controller 101 is connected to the drive circuit 102 of the motor 34, the acoustic circuit 103 of the alarm sound generator 16, and the lighting circuit 104 of the alarm light generator 17, and takes in output values from the anemometer 15 and the position sensor 35. The input circuit 105 is connected.

When the wind speed measured by the anemometer 15 reaches a certain level or higher, the wind warning device 11 according to the present embodiment raises the flag 14 to notify the danger. A sequence executed by the control unit 101 at this time will be described with reference to FIG.
As shown in FIG. 4, the control unit 101 is on standby for determining whether a predetermined X time has elapsed (step S <b> 101). This is to see if time T has become X. When the time T becomes X (YES in step S101), the output of the anemometer 15 is taken in via the input circuit 105, and wind speed measurement is executed (step S102).
Subsequently, the control unit 101 sets the wind speed based on the output of the acquired anemometer 15 as the wind speed V ₀ and determines whether or not the wind speed V ₀ exceeds the specified value Y (step S104). This process is a process for determining whether or not the measured value of the anemometer 15 has reached a prescribed wind speed region. Thus the process of step S104 may be a process of determining whether the wind speed V ₀ becomes less than a prescribed value Y.
What is important here is the specified value. The specified value is set as a watershed between a safe wind speed and a dangerous wind speed when working at a high place in a facility where the wind warning device 11 is installed. If the wind speed V ₀ does not exceed the specified value Y or is less than or equal to the specified value Y, it is safe, and if the wind speed V ₀ exceeds the specified value Y or exceeds the specified value Y, it is dangerous.
If the wind speed V ₀ does not exceed the specified value Y (NO in step S104), the sequence returns to the process in step S101.
If the wind speed _{V 0} exceeds a specified value Y contrary (YES in step S104), and the control unit 101 executes the process of raising the flag 14 (step S105). That is, the motor 34 is driven to rotate, whereby the belt 32 of the lifting mechanism 31 is rotated to lift the flag 14. This is the first alarm process. At this time, the control unit 101 takes in the output of the position sensor 35 that detects the mark attached to the belt 32, monitors the height position of the flag 14, and raises the flag 14 to the highest level.
The control unit 101 also drives the alarm sound generator 16 to sound an alarm sound (step S106). It is an acoustic alarm process. Then, the control unit 101 drives the warning light generator 17 to emit warning light (step S107). This is a light emission alarm process. Thereafter, the process returns to step S101.

Thus, according to the present embodiment, when the wind speed measured by the anemometer 15 reaches a certain level or more, the flag 14 can be raised to notify the danger. As a result, even in a facility with a large area such as a power plant and a lot of buildings and facilities, it can be seen at a glance from various places that the wind speed has reached a certain level. As a result, a person in the position of a person in charge of work, such as a field supervisor, can check whether the wind speed is dangerous without going to the place where the anemometer is installed. Can help to ensure safety.
In the present embodiment, when the wind speed reaches a certain level or more, the danger is notified not only by raising the flag 14 and notifying the danger but also by sounding an alarm sound. Thus, information that the wind speed has reached a dangerous speed range for work can be transmitted more reliably.
For example, it is assumed that the wind speed did not reach the dangerous speed region at the start of the work, but entered the dangerous speed region during the work. In such a case, when working in a place where the raised flag 14 cannot be seen, or at least the person in charge cannot see the flag 14, the risk of wind tends to be forgotten. On the other hand, if a warning sound is sounded during work, the person in charge of the work can recognize that the wind speed has reached a dangerous speed region by moving to a place where the raised flag 14 can be visually recognized. Thus, work safety is ensured.
What is important in this case is that the flag 14 notifies that the wind speed has entered a dangerous speed range. This is because even if the flag 14 cannot be directly visually recognized at the work site, it can be easily confirmed that the flag 14 is lifted by moving to a place where the flag 14 can be seen by using an alarm sound.
Another important point is that the warning lamp 72 of the warning light generator 17 emits light at the top of the pole 13 when the wind speed reaches a dangerous speed range. The person in charge of work who tries to move to the place where the flag 14 can be seen by using the alarm sound is led to a position where the raised flag 14 can be visually recognized by the warning lamp 72 that is lit. That is, the warning lamp 72 causes a guiding action to a position where the raised flag 14 can be visually recognized.
In the present embodiment, the anemometer 15 and the alarm sound generator 16 are also attached to the pole so as to be positioned on the top of the pole 13, that is, above the flag 14 in the uppermost position. Thereby, the rotation of the wind receiving portion 52 included in the anemometer 15 and the transmission of the sound emitted from the alarm sound generating device 16 are not hindered by the raised flag 14. Moreover, since the rotating body 51 of the anemometer 15 is positioned at a high place, the wind speed can be measured at a height close to the work place.

[Second Embodiment]
A second embodiment will be described with reference to FIG. The same parts as those of the first embodiment are denoted by the same reference numerals, and description thereof is also omitted.
This embodiment is an embodiment of a wind alarm device.

As shown in FIG. 5, the control unit 101 executes a process of adjusting the height of the flag 14 between the wind speed measurement in step S102 and the comparison process in step S104 (step S103). Second alarm processing. This process is a process of raising and lowering the flag 14 linearly according to the output value of the anemometer 15 without raising the flag 14 to the highest position. The flag 14 is raised higher as the wind speed increases. The flag 14 is raised and lowered by driving and rotating the motor 34.
Control unit 101, when determining that the wind speed _{V 0} exceeds a specified value Y in step S104 (YES in step S104), and is raised to the highest position flag 14 (step S105)

As described above, according to the present embodiment, even if the wind speed V ₀ does not exceed the specified value Y, in other words, even if the wind speed does not reach a dangerous speed range for work, the anemometer 15 The flag 14 is moved up and down according to the wind speed measured by. Therefore, the height position of the flag 14 at a stage where the wind speed does not reach a dangerous speed range for work indicates the degree of the wind speed. In this way, the person in charge of work can check the current wind speed state. For example, it is possible to know from the height of the flag 14 whether it is completely safe, a state that requires a little attention, or a state that requires considerable attention. .

[Third Embodiment]
A third embodiment will be described with reference to FIG. The same parts as those in the first and second embodiments are denoted by the same reference numerals, and description thereof is also omitted.
This embodiment is an embodiment of a wind alarm device.

As shown in FIG. 6, in the height adjustment process of the flag 14 in step S <b> 103, the control unit 101 changes the height position of the flag 14 from the lowest position to the highest according to the magnitude of the output value of the anemometer 15. Adjust linearly between positions. The process of step S105 in the first and second embodiments is not executed. When the wind speed V ₀ exceeds the specified value Y (YES in step S104), in other words, when the wind speed reaches a dangerous speed range for work, an acoustic alarm process (step S106) and a light emission alarm process (step S107). ) And only run.

  Thus, according to the present embodiment, the position of the flag 14 is linearly adjusted according to the speed of the wind speed, the position of the flag 14 is lowered when the wind speed is slow, and the position of the flag 14 is increased as the wind speed is fast. To do.

The wireless communication circuit 106 is connected to the control unit 101 of the wind alarm device 11 and wirelessly transmits an alarm signal from the antenna 107 based on a command from the control unit 101.

As shown in FIG. 8, the wind alarm device according to the present embodiment includes a portable terminal 201 as a device that receives an alarm signal wirelessly transmitted by the wind alarm device 11. The portable terminal 201 has a display 203 on the front surface of a flat housing 202. A touch panel 204 is provided on the display 203. The housing 202 has a plurality of acoustic holes 205 below the display 203. This is because sound emitted from the speaker 231 (see FIG. 9) is emitted to the outside of the housing 202.
In the present embodiment, the portable terminal 201 is carried by a person in charge of work or a worker.

As illustrated in FIG. 9, the mobile terminal 201 includes a control unit 251 that controls each unit by executing a predetermined sequence. The control unit 251 is a sequencer as an example, and a microcomputer as another example. Connected to the control unit 251 are an output circuit 252 of the display 203, an input circuit of the touch panel 204, an acoustic circuit 254 that drives the speaker 231 to generate sound, and a wireless communication circuit 255.
The wireless communication circuit 255 is a circuit that receives a measurement value of the anemometer 15 wirelessly transmitted by the wind warning device 11. The measurement value is received via the antenna 256.

As shown in FIG. 10, when the wind speed V ₀ based on the output of the anemometer 15 exceeds the specified value Y (YES in Step S <b> 104), the control unit 101 of the wind warning device 11 raises the flag 14 (Step S <b> 104). Prior to S105, an alarm signal is wirelessly transmitted by the wireless communication circuit 106 (step S151).
When the control unit 251 of the portable terminal 201 receives an alarm signal via the wireless communication circuit 255, the control unit 251 notifies the alarm.

They can be notified that they have become. As a result, work safety can be ensured.

[Fifth Embodiment]
A fifth embodiment will be described with reference to FIGS. The same parts as those in the first to fourth embodiments are denoted by the same reference numerals, and description thereof is also omitted.
This embodiment is an embodiment of a wind warning system.

As shown in FIG. 11, in the present embodiment, the control unit 101 of the wind alarm device 11 is based on the measured value of the anemometer 15, that is, the output of the anemometer 15, not the alarm signal (step S <b> 151 in FIG. 10). the wind velocity _{V 0} wirelessly transmits (step S171). The timing of wirelessly transmitting the wind speed V ₀ is after the wind speed measurement in step S102 and before the determination of whether the wind speed V ₀ exceeds the specified value Y in step S104.
The flowchart shown in FIG. 11 is based on the first embodiment (the flowchart shown in FIG. 4). However, in the implementation, the second embodiment (the flowchart shown in FIG. 5) or the third embodiment is used. (The flowchart shown in FIG. 6) may be used as a basis. Also in those embodiments, after the wind velocity measuring step S102 has been performed, the wireless values of wind speed V ₀ by the wireless communication circuit 106 before determining whether the wind speed V ₀ exceeds a specified value Y in step S104 What is necessary is just to transmit (step S171).

The portable terminal 201 does not receive an alarm signal when the wind speed V ₀ based on the output of the anemometer 15 exceeds the specified value Y, but always receives the measured value of the anemometer 15 called the wind speed V ₀ . Then, the portable terminal 201 uniquely determines whether or not the wind speed V ₀ exceeds the specified value Y based on the received wind speed V ₀ which is the measured value of the anemometer 15. At this time, the portable terminal 201 sets the height of the work place in advance, and corrects the value of the received wind speed V ₀ according to the set height.

  As illustrated in FIG. 12, the control unit 251 of the mobile terminal 201 displays a menu screen 301 </ b> A on the display 203. The menu screen 301A displays a height setting button 302A, a work button 303, and a maintenance button 304, and provides the operator with a menu of height setting, work, and maintenance, respectively. These height setting button 302A, work button 303, and maintenance button 304 are objects that can be touch-selected on the touch panel 204.

  As illustrated in FIG. 13, the control unit 251 of the mobile terminal 201 sets the height by the touch tip of the height setting button 302A (step S201A), the work by touch selection of the work button 303 (step S202), and the maintenance button 304. Is waiting for execution of maintenance (step S203) by touch selection.

When the height setting is selected (YES in step S201A), the control unit 251 of the portable terminal 201 executes a height setting process (step S204).
As shown in FIG. 14, in the height setting process (step S204 in FIG. 13), the height list screen 311A (see FIG. 12) is displayed on the display 203 (step S251A).
As shown in FIG. 12, the height list screen 311A provides a high setting area 313A below the title bar 312 titled “Height list”. The high setting area 313A displays a height display indicating the height in increments of 10 m to 5 m. These height displays are objects that can be touched on the touch panel 204. The high setting area 313A sequentially displays higher height displays by performing a feeding operation with a finger.
The person in charge of the work touches and designates the height of the place where the work is to be performed on the touch panel 204.

As shown in FIG. 14, if the height is selected by touch designation on the touch panel 204 from the height list screen 311A (see FIG. 12), the control unit 251 of the portable terminal 201 (YES in step S252). A confirmation screen 331A (see FIG. 12) is displayed on the display 203 (step S255A).
As shown in FIG. 12, the confirmation screen 331A provides a confirmation area 333 below the title bar 332 entitled “Confirmation”. The confirmation area 333 displays the set height and provides a setting button 334 and a cancel button 335. These setting button 334 and cancel button 335 are objects that can be touch-selected on the touch panel 204.

As illustrated in FIG. 14, the control unit 251 of the mobile terminal 201 waits for determination of touch designation of the setting button 334 (step S256) or touch designation of the cancel button 335 (step S257) using the touch panel 204 (step S256). -Step S257). If the cancel button 335 is touched (YES in step S257), the process returns to the display process of the height list screen 311A in step S251A.
On the other hand, when the setting button 334 is touched (YES in step S256), the height displayed in the confirmation area 333 (see FIG. 12) of the confirmation screen 331A is set as the height of the work place (step S258A). The coefficient a is set (step S259). The coefficient a is a value that is multiplied by the value of the wind speed V ₀ based on the output of the anemometer 15 received wirelessly from the wind warning device 11 during work according to the height of the selected work place. For example, assuming that the anemometer 15 is installed at a height of 10 m from the ground surface G, the wind speed at the work place should be faster as the work place becomes higher than 10 m. Therefore this case is not set in accordance with the height of the selected work area, the coefficient a to a higher value of the wind velocity V ₀ received from the wind alarm device 11 (step S259).
The control unit 251 of the mobile terminal 201 includes a sequence for calculating a value of the coefficient a suitable for each height.

As shown in FIG. 15, if the control unit 251 of the mobile terminal 201 sets the coefficient a (step S259 in FIG. 14), the work screen 351A (see FIG. 12) is displayed on the display 203 (step S260A).
As shown in FIG. 12, the work screen 351A provides an alarm area 353 below the title bar 352 entitled “Working”. The alarm area 353 displays a display column for work height, wind speed, and status, and provides a menu button 354 and a reset button 355. These menu button 354 and reset button 355 are objects that can be touch-selected on the touch panel 204.
Of the display items displayed in the alarm area 353, the work height is already selected and known, so the selected height is displayed.

As shown in FIG. 15, the control unit 251 of the portable terminal 201, if displaying the work screen 351A on the display 203 (step S260A), the measured value of the anemometer 15 from the wind alarm device 11, i.e. the reception of wind speed _{V 0} (Step S261).
Upon receiving the wind speed _{V 0} (YES at step S261), the wind speed _{V 0} received multiplied by a coefficient a set in step S259 in FIG. 14 for calculating the wind speed _{V 1} (step S262). And displaying the calculated wind velocity _{V 1} in the warning area 353 in the work screen 351A displaying on the display 203 (step S263).

Then, the control unit 251 of the mobile terminal 201 determines whether the wind speed _{V 1} calculated in step S262 exceeds a specified value Y (step S264). This process is a process for determining whether or not the wind speed at the work place based on the measurement value of the anemometer 15 provided in the wind warning device 11 has reached a prescribed wind speed region. Thus the process of step S264 may be a process of determining whether the wind speed V ₁ is equal to or larger than the specified value Y.
If the wind speed _{V 1} is not greater than the predetermined value Y (NO in step S264), the state field of the warning area 353 in the work screen 351A displaying on the display 203,: displays "state safe" (step S265 ).

The work place setting area 313B displays individual work places in a facility where the wind warning system of the present embodiment is used. These work place displays are objects that can be touched on the touch panel 204. The work place setting area 313B sequentially displays work places that do not fit on the display 203 by performing a feed operation with a finger.
The work place setting area 313B displays the work areas in a hierarchical manner. For example, a work area “building A” will be described as an example. This “Building A” has “outer staircase” and “chimney staircase” as work areas, and “outer staircase” and “chimney staircase” further have “first group” to “nth group”. To do. “Group” means, for example, several stages from a landing to the next landing. In this case, “Building A” is the first level, and “Outer staircase” and “Chimney staircase” are the second level. “First group” to “n-th group” in the “outer staircase” are the third hierarchy, and “first group” to “n-th group” in the “chimney staircase” are the third hierarchy. Therefore, the work place setting area 313B displays a work place having a concept similar to that including “Building A” on the first level screen, and when “Building A” is selected, the “Outer staircase” is displayed on the second level screen. And “chimney staircase” are displayed. For example, when “chimney staircase” is selected, “first group” to “nth group” are displayed on the third layer screen. Thus, the worker can reach the final level.
The person in charge of the work touches the touch panel 204 to specify the work place where the work is to be performed.
