Description

  The present invention relates to an open / close gate open / close control system.

  Automobile roads such as expressways include emergency vehicles such as road construction vehicles, traffic accident handling vehicles, fire extinguishing handling vehicles, vehicles for transporting people with accidents, and work vehicles such as snowplows from general roads along the road. An emergency approach path or emergency exit path is provided so that the expressway can be accessed directly or from the expressway to a general road along the road. Ordinary vehicles are closed at the gate so that general vehicles cannot enter or leave, and when the predetermined vehicle needs to pass through, a predetermined worker operates the remote control at the installation site of the gate, Alternatively, an appropriate control means arranged at the installation site of the gate is operated to open or close the gate to open the gate entrance and exit after passing the vehicle. Work to say that returning the over door in the closed state is running.

  By the way, the gate installed at the entrance / exit of this emergency approach path is conventionally unwound from the winding drum as shown in, for example, Japanese Patent Application Laid-Open No. 2008-291528 (Patent Document 1). The gate body suspended by the wire rod is arranged to be movable up and down at the entrance and exit, and the winding drum is rotated to wind up the wire to raise the gate body and open the entrance. In general, the gate body is lowered by unwinding the wire to close the doorway of the gate body.

In such a conventional wire lifting type lifting gate, the wire 32 for suspending the gate body 33 is always in a tensioned state due to the weight of the gate body 33, and as shown in FIG. When an obstacle 38 such as snow piled up on the descending orbit of the body 33 or a snow lump caused by snow removal exists on the descending orbit, the gate body 33 comes into contact with the obstacle 38 and the gate body There has been a frequent problem of stopping before moving to a predetermined position (lowest point).

  At this time, even if the gate body 33 stops halfway, the unwinding of the wire 32 does not stop immediately, and the winding drum 31 does not stop until a predetermined amount of the wire 32 is unwound. The wire rod 32 is loosened, and the wire rod 32 is loosened. As a result, the wire rod 32 wound around the winding drum 31 in an regularly aligned state spreads outward and becomes an irregular state. When the wire is wound up, it becomes turbulent, and the wire rod 32 is caught or entangled with each other, causing malfunctions such as malfunction of the winding drum 31.

  Therefore, in order to solve such a conventional problem, for example, as shown in Japanese Patent No. 5178945 (Patent Document 2), it is unwound from a winding drum 1 and suspended by a wire 2 suspended from above. The provided gate body 3 is disposed at the entrance / exit 5 of the entrance / exit gate 4 so as to be movable up and down, and the winding drum 1 is rotated to wind up the wire 2 to raise the gate body 3. On the other hand, in the wire lifting type elevating gate configured to close the doorway 5 by lowering the gate body 3 by unwinding the wire 2, the wire 2 is attached to the wire 2. When the gate body 3 is wound up and lifted and lifted, a retaining locking portion 6 is provided to be locked to the gate body 3, and when the wire 2 is wound, the retaining locking portion 6 becomes the gate body. Locked to 3 The wire body 2 is further wound up in a state in which the retaining locking portion 6 is locked to the gate body 3 so that the gate body 3 is lifted and lifted, and a weight 7 is attached to the suspended wire 2. The wire 2 is pulled down and urged by the weight 7, and the gate 2 is unwound and the gate 2 is unwound and locked in the state in which the retaining lock 6 is retained. When the main body 3 is lowered, even if the gate main body 3 stops during the lowering or the lowering speed decreases due to the obstacle 8 present on the descending track of the gate main body 3, the weight 7 is used as the winding drum. Even if the gate body is stopped in the middle of lowering by an obstacle present on the lowering trajectory, the gate 2 is configured so that the wire 2 is not slackened by moving downward with the unwinding amount of 1. The body Set to turbulent wound without slack wire rod has is been to provide excellent wire hoisting lift gate practicality does not occur.

  However, a more important problem in the opening / closing control of the lift gate is that the lift gate is always equipped with emergency vehicles such as emergency road repair work vehicles, fire engines, ambulances, police vehicles, etc. Therefore, it is extremely important to reach the destination safely and promptly, accurately and reliably. For this reason, the opening / closing device of the lifting gate is open and closed at any time without any failure. It is important that the management is maintained in such a way as to be executed reliably.

If a part of a certain expressway has a formal vehicle entry or exit road, and it is in the middle road area of the place where the formal vehicle entry or exit road is provided Then, even though there is no further formal vehicle approach path or vehicle exit path, in the meantime, in the situation where the emergency approach path or emergency exit path described above is provided, If there is a neurosurgery-related emergency hospital in the vicinity of the emergency approach path or emergency exit path, for example, a road area in the middle of the place where the formal vehicle approach path or vehicle exit path is provided In the case of a car accident that happened to happen to be accidentally passed through the accident site on the expressway, the accident was injured by the accident and transported to the emergency hospital. Vehicle Open the gate by a worker at the site, or a worker in the remote management section at a remote location, and take the ambulance down the expressway through the emergency exit route, It becomes possible to transport the injured person to the emergency hospital in a short time and efficiently.

However, if the gate opening / closing device on the emergency exit path breaks down and the gate cannot be opened, the ambulance goes to the place where the official vehicle exit path is provided and makes a detour. There is then a risk of going to the emergency hospital, which takes extra time and money, and results in the loss of life.
Similarly, if there is a situation where the gate cannot be used or closed, this should not be due to the need to prevent the entry of suspicious vehicles, the occurrence of illegally entering vehicles, the entry of animals, etc. Needless to say, it is necessary to have an awareness of the problem.

Such an example is merely an example of the gate opening and closing device according to the present invention. In short, the gate provided on the emergency vehicle approach path or the emergency vehicle exit path is always normal in any environment. In addition, it is necessary to be maintained and managed so as to operate accurately, and even if a slight malfunction occurs, a strict maintenance operation that must never be performed is always required.
However, up to now, including the above-mentioned known examples, there has been almost no examination for solving the above-mentioned problems, and an important solution is how to construct a detection system and a monitoring system for that purpose. It has been recognized as an issue.

Hereinafter, the configuration of a specific example of the lift gate opening / closing control system 100 according to the present invention will be described in detail with reference to the drawings.
An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

That is, FIG. 1 is a side view showing the configuration of a specific example of the opening / closing control system 100 for the lift gate according to the present invention.
At least two pairs of strut members 25 having a desired height, which are vertically arranged in parallel with each other at a desired interval, and the strut members disposed between the strut members 25 The gate main body 30 is composed of a single connecting beam part 16 and a gate part 30 configured to be movable up and down, and at least a part of the gate part 30 is at least one of the one part. It slides along the surface of the column member 25 or along the internal space 121 of the column member 25, or at least a part of the gate portion 30 is at least along the surface of the one column member 25, Alternatively, by being engaged with the movable member 26 that slides along the internal space 121 of the column member 25, the entire gate main body 3 that is configured to be movable in the vertical direction, In a state where at least a part of the moving member 26 or the gate main body portion 3 is suspended by one end portion of the wire member 2 engaged with the rotational drive body 1 capable of rotating in the forward and reverse directions, the length of the column member 25 is long. An elevating gate opening / closing control system 100 constituted by rotary driving means 11 configured to arbitrarily slide the gate main body portion 3 in the vertical direction along the axial direction, and the strut The position of the gate portion 30 in the state (A1) where the opening of the gate portion 30 is completed along the surface of at least one of the support members 25 of the member 25 or in the vicinity of the one support member 25 In this case, the first sensor unit (upper stop position detecting unit) 13 having a function of detecting the position of a specific part in the gate unit 30 set in advance and the gate unit 30 are closed. In the state (A2), at a position (A3) separated from the position where the gate unit 30 exists by a predetermined distance above the specific position, the specific part of the gate unit 30 set in advance is The second sensor unit (lower stop position detection unit) 14 having a detecting function and a moving speed when the gate unit 30 is raised in a desired lower part than the arrangement part of the first sensor part 13 Or a third sensor portion (upper deceleration) for detecting the specific portion of the gate portion 30 provided at a portion where the movement speed when the gate portion 30 is lowered is increased. (Detection unit) 12 and a desired upper part of the second sensor part 14 and a lower part of the third sensor part 12, and the moving speed when the gate part 30 is lowered is determined. Slow down or A fourth sensor unit (lower deceleration detection unit) 15 for detecting the specific part of the gate unit 30, which is provided in a part where it is necessary to increase the moving speed when the gate part 30 is raised; At the same time, the second sensor part 14 is provided with a timer means 103, and the second sensor part 14 detects the passage of the specific part of the gate part 3. After that, an elevating gate opening / closing control system 100 is shown which is configured to stop the lowering operation of the gate unit 3 after a time arbitrarily set by the timer means 103 has elapsed. ing.

The configuration of the gate body 3 used in the lift gate opening / closing control system 100 according to the present invention is not particularly limited, but a general configuration is as illustrated in FIG. And at least two pairs of strut members 25 having a desired height, which are vertically arranged in parallel with each other at a desired interval, and stretched between the strut members 25 A frame body portion having a structure constituted by a single connecting beam portion 16 disposed, and an upper edge frame 18 and a lower edge frame 18 'left and right edge frames provided inside the frame body The gate portion 30 in which a plurality of rod-shaped reinforcing rod-like bodies 19 are arranged in the vertical direction inside the frame portion constituted by the portions 17 and 17 ′ is provided along the surface of the column member 25 or It slides along the internal space portions 120 and 121 of the column member 25. Its entirety is wetted moving member 26 and engaging mating is one embodiment it is desirable one that is configured to be movable in the vertical direction.

One end of the wire member 2 is coupled to one of the gate portion 30 and the movable member 26 according to the present invention, whereby the gate portion 30 is suspended in a state where it is suspended from the wire member 2. What is configured to be driven in the direction is a specific example of the gate body 3 that is simple and inexpensive.
Although the constituent material of the gate main body 3 in the present invention is not particularly limited, for example, it is preferable that it is made of a rigid metallic material including an iron material or an aluminum material. .
In addition, the height and width of the gate body 3 according to the present invention are not particularly limited. For example, considering that the height of a snowplow has recently increased, The column member 25 may have a height of 10 m or more, and the width is a specific example that desirably covers at least two lanes.
Furthermore, it is preferable that the height of the gate portion 30 is 1 m to 2 m.

On the other hand, as a drive system for sliding the gate part 30 up and down in the gate main body part 3 according to the present invention, a chain type, a spiral spiral screw type, a hydraulic type, etc. can be used. In cold regions in the snowy country, there are problems such as temperature effects and snow freezing. Using the metal wire 2 and the rotating drive body mainly composed of an electric motor, the wire 2 It is the most preferable specific example to employ a system that performs unwinding and winding.

By the way, in the present invention, the stationary position A1 above the gate portion 30 in the gate body portion 3 is a vehicle in which the position of the lower edge portion 18 'passes through the gate body portion 3. It is desirable to set the height so that a special vehicle expected to be the highest in the group, such as a snowplow, can pass.

Further, the stationary position A2 below the gate portion 30 in the gate main body portion 3 in the present invention achieves the purpose of preventing small animals and the like from entering the expressway at the same time. Ideally, it should be set at a position that is in direct contact with the road surface.However, if there is snow in the winter, the result of snow removal work on the snow on the road surface due to the snowfall When the remaining snow is accumulated on both sides of the road, and when the accumulated portion 8 due to snow is also formed on the base portion of the gate body portion 3 according to the present invention, the portion prevents the lowering operation of the gate portion 30, In many cases, the lowering edge portion 18 ′ of the gate portion 30 must end the descending operation of the gate portion 30 in a state where the lower end edge portion 18 ′ is not completely in contact with the road surface portion.

If such a state is left as it is, an excessive load or impact is applied to each member and device of the gate main body 3, so that the device is frequently damaged or broken, and the above-mentioned snow accumulation is caused. If the height of the accumulation portion 8 is different on the left and right, it becomes impossible for the upper end edge 18 and the lower end edge 18 'of the gate portion 30 to maintain a complete horizontal position, and the pair of pillars forming the pair There also occurs a situation in which the member 25 is inclined and cannot be moved up and down.
Needless to say, the repair work in that case is quite troublesome.
Therefore, in the present invention, the stationary position A2 below the gate portion 30 is a position where the lower end edge portion 18 'of the gate portion 30 is set to a position in direct contact with the road surface. Instead, it is set to a site where a certain amount of space can be formed between the lower edge 18 'of the gate 30 and the road surface.
This position is considered as a temporary stationary position A2 of the gate unit 30.

The height of the space between the surface of the road and the lower edge 18 'of the gate 30 in the present invention is not particularly limited, but the land environment where the gate body 3 is installed. It can be set as appropriate in consideration of the weather environment, seasonal factors, the moving speed of the gate section 30 and the like.
In the present invention, the provisional stationary position A2 below the gate portion 30 is determined and the gate portion 30 is moved from the provisional stationary position A2 while the desired space is provided. Further, the lowering is continued, and finally, it is configured to stop at a desired lower position.

Specifically, for example, in the desired area where the gate main body portion 3 is set, the height of the accumulation portion 8 is 50 cm on average from the ground surface by snow removal work during snowfall. Is estimated to be below the gate portion 30 such that the height of the space between the surface of the road and the lower edge 18 'of the gate portion 30 is, for example, 60 cm to 70 cm. The temporary stationary position A2 in this case.
In the present invention, when the gate unit 30 performs the lowering operation, the gate unit 30 does not stop the lowering operation after the gate unit 30 has passed the temporary stationary position A2. Control is performed so that the gate portion 30 is lowered to a position where it substantially contacts the upper surface portion of the deposition portion 8, and the lowering operation is stopped there.

Specifically, if the lowering speed of the gate unit 30 is set in advance, the time setting in the timer means 103 is appropriately selected using the appropriate timer means 103 in consideration of the lowering speed. It is possible to execute easily.
In other words, in the present invention, due to seasonal factors or geographical factors, the lowering operation after the gate unit 30 has passed through the temporary stationary position A2 is continued by the timer means 103. By setting the time appropriately, it is more realistic and it is possible to minimize the risk of occurrence of failure or damage.

The limit or adjustment of the rotation driving time of the driving unit 1 in the timer unit 103 can be arbitrarily set by manual operation by an operator, or a wireless, infrared, light, or other medium is used. Thus, it is also a desirable specific example that the timer driving time can be automatically set without contact from a remote place.
Further, the timer setting time may be automatically changed using an appropriate program.

In this case, a space portion is generated between the lower end edge portion 18 ′ of the gate portion 30 and the road surface. From this portion, various animals may enter the expressway. A plurality of flat and flexible sheet members 23 made of fabric, rubber, synthetic resin material, and the like are attached in parallel from the lower edge 18 'of the portion 30 to the lower surface, and the space portion It is also a desirable specific example to be configured so as to be closed.

In the specific example of the present invention, when the accumulation portion 8 due to the snow does not exist, or when the height of the deposit decreases with time, the set time of the timer is set. It is possible to cope with this by setting it appropriately long, and the maximum time corresponds to the fact that the lower edge 18 'of the gate portion 30 is in direct contact with the road surface.
That is, as another aspect of the present invention, the time setting of the timer means 103 can be adjusted manually or directly or remotely through an appropriate program in response to seasonal information. It is characterized by being.

Next, as shown in FIG. 2, in the gate main body 3 according to the present invention, the gate portion 30 has at least a part of both end portions thereof as support members 25 that form a pair. It may be configured to slide up and down in accordance with the driving state of the wire 2 in a state of being fitted in an appropriate slit portion 120 or inner groove portion 121 provided, or as shown in FIG. Similarly, the gate part 30 is in a state in which at least a part of both ends thereof are fitted in the appropriate slit part 120 or the inner groove part 121 provided in the pair of support pillar members 25. You may be comprised so that it may engage with the movable member 26 comprised so that it may slide up and down according to the drive condition of the wire 2, and it may slide up and down.

In the present invention, when the gate portion 30 is moved a specific distance in the vertical direction while sliding along each of the pair of column members 25, the end portion of the wire portion 2 is fixed. An appropriate anti-friction means, for example, a sliding material, is provided on a part of the gate portion 30 that is in contact with the inner wall surface portion of the slit portion 120 of the column member 25 or the recessed groove portion 121 of the column member 25. It is desirable that a means such as a rotating roller 122 is provided, and a part of the gate portion 30 is formed in the groove portion 121 having a concave or H-shaped cross section of the column member 25. It may be configured to move in a vertical direction by being engaged and fixed to a movable member 26 that is moved and slid by a specific distance in the vertical direction and to which the end of the wire portion 2 is fixed. Even in this case A part of the surface of the movable member 26 has a slit portion 120 of the column member 25 or a portion where the cross section of the column member 25 is in contact with the inner wall surface portion in the groove 121 having an H shape or a U shape. Appropriate anti-friction means, for example, means such as a sliding material, a rotating roller 122, etc., are preferably provided.

Further, in the present invention, in particular, when the gate main body 3 arranged in a region where the amount of snowfall is large in winter, for example, most members are made of iron material, the iron material is When the temperature is low, it is easy to cool. Therefore, if a considerable amount of snow adheres and accumulates in the gap portion of the slit portion 120 or the groove portion 121 of the column member 25, the portion freezes. As a result, it becomes a hard mass, and as a result, the vertical movement of the gate unit 30 is restricted or inoperable.
In some cases, a part of the gate part 30 is destroyed or damaged, and thus it is necessary to always avoid such a state.

Therefore, in the present invention, as shown in FIG. 4, a part of the gate part 30 sliding in the slit part 120 or the groove part 121 or a part of the movable member 26 is attached to the part. It is desirable to attach at least one scraper part 35 having a function capable of removing the accumulated snow and discharging it to the outside of the slit part 120 or the groove part 121.
In the specific example of the present invention, the material of the scraper portion 35 may be a metal or a synthetic resin containing FRP.
Further, the number of the scraper portions 35 and the respective dimensions are not specified, and can be arbitrarily set. Preferably, the tip portion is formed in a blade state, and the blade edge portion is It is desirable that it is attached so as to face the edge of the slit 120 and the inner wall surface of the groove 121 with a gap of about 2 to 5 mm, for example.

It goes without saying that such a configuration functions effectively not only when the object is snow but also when earth and sand or small rocks are accumulated between the slit portions 120 or in the groove portions 121.
That is, the scraper portion 35 according to the present invention is formed on the inner wall surface portion of the column member 25 on at least a part of the movable member 26 or the gate portion 30 that slides along the internal space 121 of the column member 25. And slidable with respect to the inner wall surface portion while being opposed to each other through a fine interval.

Next, in the present invention, as described above, the gate portion 30 is wound between the supporting column members 25 forming the pair of the gate main body portion 3 by using the driving means 11. By removing or unwinding, the gate member 30 moves and slides in the vertical direction along the longitudinal direction of the column member 25. However, since the gate portion 30 itself has a considerable weight, it is at a high speed. Since this drive control is dangerous and causes direct damage and failure, it is basically desirable to drive the gate unit 30 up and down at a low speed.

The vertical movement drive speed of the gate unit 30 is not particularly limited, but can be set to about 5 cm to 15 cm per second (first speed), for example.
That is, as yet another aspect of the present invention, for example, the ascending and descending speed of the gate unit 30 is basically a section between the third sensor unit 12 and the fourth sensor unit 15. In this case, the first speed is set to a high speed state, and between the first sensor unit 13 and the third sensor unit 12 and between the fourth sensor unit 15 and the second sensor unit 14. In the section between the lift gate opening and closing control system, the second speed is set to a low speed state. Further, as a different aspect, for example, the second speed 12. The descending gate opening / closing control system according to claim 11, wherein the speed is set to a speed corresponding to 5 to 30%, preferably 10 to 20% of the first speed. good.

In the present invention, the operation of stopping the heavy gate portion 30 in a predetermined place and the operation of starting driving from the predetermined place also prevent occurrence of failure, breakage of members, and the like. From the necessity, it is desirable to operate accurately and safely in a stable state. Therefore, in the present invention, the operation of stopping the gate unit 30 in a predetermined place and driving from the predetermined place are performed. It is desirable that the starting operation is driven in a slow and stable state at a speed (second speed) slower than the first speed.
The vertical movement drive speed of the gate unit 30 is not particularly limited, but may be set to a speed set to be 50% to 80% reduction of the first speed, for example, about 1 cm to 7 cm per second. Is also possible.

In the present invention, the place where the vertical movement drive speed of the gate section 30 is reduced from the first speed to the second speed, or its timing, and the vertical movement drive of the gate section 30 The location or timing when the speed is increased from the second speed to the first speed is not particularly limited, but at least the gate unit after the speed change is executed. It is desirable to provide a time interval at which the effective driving speed is stable before 30 stops at a predetermined place or before reaching a place where the speed increases from the predetermined place.
The time interval according to the present invention can be set to about 2 to 5 seconds, for example, under the speed setting condition.

In order to specifically realize the above technical idea, in the present invention, a specific arrangement position of the gate portion 30 in the gate main body portion 3 when moving up and down along the column member 25 is detected. In order to do so, it is one specific example that it is desirable to provide appropriate sensor means for detecting the positions of the plurality of gate portions 30 on the surface of the column member 25 or in the vicinity thereof.
Specifically, in the present invention, for example, at least the upper stop position A1 and the lower stop position A2 of the gate portion 30 and between the both stop positions A1 and A2, and the upper stop position. Movement of the gate portion 30 set to a position A3 spaced apart by a predetermined distance D1 downward from A1 and a position A4 spaced apart by a predetermined distance D2 upward from the downward stop position A2 Desirably, appropriate sensor means 12 to 15 are provided at the speed change operation part.

That is, when the technical configuration in the present invention is described more specifically, the surface of at least one column member 25 of the column member 25 or the vicinity of the column member 25 A predetermined position of the gate portion 30 is detected at a position where the gate portion 30 is present when the gate portion 30 is completely opened in the gate body 3. The first sensor unit (upper stop position detection unit) 13 having a function and the lower end edge portion 18 'of the gate unit 30 in the gate main body unit are in contact with or close to the road surface are completed. In the state, a function of detecting a predetermined specific part in the gate unit 30 at a position separated by a predetermined distance from the position where the gate unit 30 exists in the upper direction is provided. The sensor unit (lower stop position detection unit) 14 and the first sensor unit 13 are located at a desired lower site than the arrangement site of the first sensor unit 13, and the moving speed when the gate unit 30 is raised is reduced or the gate unit A third sensor unit (upper deceleration detection unit) 12 for detecting the specific part of the gate part, which is provided in a part where it is necessary to increase the moving speed at the time of descending 30; 2 at a desired location above the second sensor portion 14 and below the third sensor portion 12, and the moving speed when the gate portion 30 is lowered is reduced or the gate portion is raised. There is provided a fourth sensor unit (lower deceleration detection unit) 15 for detecting the specific part of the gate unit 30 provided in a part where the moving speed at the time needs to be increased. Things are desirable

As a preferred specific example in the present invention, the second sensor unit 14 is provided with the appropriate timer means 103 as described above, and the second sensor unit 14 is connected to the gate. After detecting the passage of the specific part of the unit 30, the timer unit 103 is operated, and after the time arbitrarily set by the timer unit 103 has elapsed, the descending operation of the gate unit 30 is stopped. It is configured.
The structure, function or performance of each of the sensor units used in the present invention is not particularly limited, and any sensor having a general sensor function conventionally used may be used. It can also be used as a proximity switch such as a sensor using light, a sensor using infrared, a sensor using electromagnetic, a sensor using electric capacity, a sensor using sound including sound, etc. The sensor means can be used.

Further, in the present invention, each of the sensors detects a predetermined part of the gate part 30 and determines whether or not the gate part 30 has reached the predetermined part. However, for this purpose, it is desirable to attach an appropriate marker 125, for example, an appropriate magnet, mirror, uneven portion, color imparting portion, etc. to a part of the gate portion 30 in advance.
In general, the sensors 12 to 15 are provided on the outer surface of the column member 25 or the inner wall surface of the inner groove 121 of the column member 25, the edge of the gate portion 30, or the outside of the movable member 26. Since it is a preferable specific example that it is attached to the part facing the surface, the marker 125 corresponds to the end of the gate portion corresponding to the substantially same height level as the upper end edge portion 101 of the gate portion 30. It is preferable to provide near the edge or near the edge corresponding to the same height level as the upper edge 101 of the gate 30 in the movable member.

In the present invention, instead of the marker 125, another marker 126 is provided in the vicinity of the edge portion of the gate portion corresponding to the substantially same height level as the lower end edge portion 102 of the gate portion 30. This is also a desirable example.
In the present invention, it is preferable to use the marker alone at any of the above-mentioned sites. However, in some cases, it is also desirable to use both the markers 125 and 126 in combination. This is a specific example.
Therefore, in another specific example of the present invention, the first and third sensors 13 and 12 detect the first marker 125 disposed near the upper end of the gate portion 30. On the other hand, the second and fourth sensors 14 and 15 detect the second marker 126 disposed near the lower end of the gate portion 30. Are configured to operate.

Further, in the present invention, when the gate unit 30 is raised to the uppermost position, there is a risk that the ascending operation is not stopped and the ascent is continued due to a mistake or some failure. Since it can be considered, it is desirable to provide a stopper unit 128 having an appropriate structure and having a function to prevent the gate unit 30 from moving up in the vicinity immediately above the first sensor unit 13.

Next, as shown in FIG. 1, the gate unit 30 in the lift gate opening / closing control system 100 according to the present invention responds to the drive operation of the drive means 11 composed of an appropriate electric motor, and It is engaged with one end of appropriate wire means 2 wound around a rotary drive body 1 composed of an appropriate rotary drum 1 that rotates arbitrarily in the reverse direction, and the forward and reverse of the rotary drum. Along with the rotation, the wire means 2 wound or unwound is slid vertically.
At that time, the wire 2 routing method provided between the rotating drum 1 and the gate portion 30 is not particularly specified, and any wire means 2 routing method is adopted. The method of routing the wire means 2 shown in FIG. 1 is also a preferred specific example.

In the present invention, it is preferable that the driving unit 11 performs necessary operations such as the rotation direction and the number of rotations using an appropriate inverter unit. In the present invention, the gate portion 30 is a movable member having a considerable weight. In particular, in the step of lowering the gate portion 30, a considerable load is applied via the wire means 2. If such a situation occurs, there is a risk that the electric motor will rotate excessively and the gate part 30 may suddenly descend due to its weight. In this case, not only is the gate portion 30 damaged, but also various members and various means in the lifting gate opening / closing control system according to the present invention are destroyed and damaged.
Therefore, in the present invention, the rotation drive means 11 is connected to the rotation drive means 11 via the appropriate brake resistor means 129 at least when the gate section 3 performs the lowering operation. It is also a preferable specific example that the function is applied.

In the present invention, as the inverter, for example, a high-frequency general-purpose inverter (FR-D700) manufactured by Mitsubishi Electric Co., Ltd. with a built-in or external brake resistor using a regenerative resistance function is used. Things are also possible.
That is, as yet another specific example in the present invention, the rotation driving means 11 is configured to be able to rotate forward and backward by an electric motor mechanism, and at the same time, at least when the gate portion 30 performs a lowering operation. Is an opening / closing control system for an elevating gate characterized in that a regenerative braking function is exerted on the rotation driving means 11 via an appropriate brake resistor means 120.

As another specific example in the opening / closing control system 100 of the lift gate in the present invention, the time setting of the timer means is performed manually or through an appropriate program in response to seasonal information. It is desirable to be able to adjust automatically by direct or remote operation.
On the other hand, as another specific example in the opening / closing control system 100 of the lift gate according to the present invention, the driving means includes appropriate control means connected to storage means containing the appropriate program. It is also a preferable specific example that it is configured so as to be driven and controlled via.

The basic control processing operation of the lift gate opening / closing control system 100 according to the present invention is performed in the vicinity of the gate body 3 at the site where the gate body 3 constituting the lift gate is provided. For example, it is executed by operating the control box 200.
The configuration of the control box 200 is not particularly limited. For example, as shown in FIG. 6, a power supply means 204 with a breaker and an inverter means are provided in a box portion having a door portion 201 that can be freely opened and closed. 203, wireless signal reception / transmission means 205, timer means 103, reset means 208, inverter means 203, preferably brake resistance means 129 with added heat dissipation means, seasonal mode switching means 209, manual gate main body opening / closing Means 210, box internal temperature adjustment switch means 211, box internal temperature adjustment means 212, data calculation control means (CPU) 213, first storage means 215 incorporating control software, and the gate section in the gate main body section 3 To detect 30 operating conditions and store the results The second storage unit 214 and the monitor unit 202 provided in the door unit 201 of the box 200 and configured to start when the door unit 201 is opened, A system start unit 400 or the like for controlling activation is provided.

In addition, in the present invention, it is preferable that the surveillance camera means 215 configured separately from the control box 200 is provided.
The main role of the monitoring camera means 215 is to determine the state of the ground surface in the gate main body section 3, particularly when the gate section 30 approaches the ground surface. Accurately communicate the actual situation to the manager in the control unit, and analyze the situation by predicting the occurrence and cause of the failure or non-operation state and the occurrence of the failure or non-operation state at an early stage. Therefore, urgent and qualified repairs and repairs can be made quickly.

Further, in the present invention, when the elevating gate 30 descends to a position close to the ground surface in the vicinity of the installation site of the gate portion 30 which is the elevating gate, the ground surface and the upper portion thereof. A monitoring camera 215 that monitors the environmental conditions in the vicinity including the monitoring camera 215 is installed, and a monitoring image taken by the monitoring camera 215 is transmitted to the control unit 300 at a remote location different from the installation site of the lift gate 30. It is a specific example that is preferably configured so that the monitoring image can be displayed on the operation status information display unit 302.
When an operator or an administrator performs an operation for opening or closing the gate portion 30 in the gate main body portion 3 on the site, when the door 201 of the control box 200 is opened, The box 200 is turned on to illuminate the inside of the box 200, and the monitor unit 202 is also turned on, and predetermined information is displayed on the image display unit of the monitor unit 202. ing.
The reset means 208 according to the present invention can be recovered normally by performing a reset processing operation when the gate section 30 according to the present invention stops its opening / closing operation. Therefore, the switch is an operation switch to be operated first when an operator finds a defect in the gate unit 30.

Further, the manual gate main body opening / closing means 210 according to the present invention allows an operator to manually perform an opening operation and a closing operation of the gate portion 30 and an operation for stopping those operations. The changeover switch means is constituted.
On the other hand, the radio signal receiving means 205 can be used, for example, in the vicinity of the site where the gate main body unit 3 is deployed, using an appropriate remote controller or the like without an operator operating the control box. This is for receiving a control signal from the remote controller so that the manual gate body part opening / closing means 210 can be remotely operated to open or close the gate part 30 or to stop the operation.
Of course, it goes without saying that the radio signal receiving means 205 is configured to be able to receive the same type of control signal transmitted from the remote location control unit 300 described later.

Further, the season mode switching means 209 in the present invention requires that the box internal temperature adjustment switch means 211 adjust the temperature in the box according to the season. For example, in the winter, at a cold temperature, Since the computer may be damaged, it is necessary to maintain the temperature inside the box at a high level, so it is possible to switch between the winter control mode and other control modes manually or remotely. It is a switch means that can.
In the present invention, after the seasonal mode switching means 209 is turned on based on the selection of the winter mode and the other seasonal modes, the box internal temperature is turned on. The adjusting means 212 is operated to set the temperature in the box suitable for the seasonal mode.
Although these operations are executed manually, it goes without saying that it is possible to perform software control operations using software.

Further, as described above, the timer means 103 determines at what timing the gate unit 30 is stopped after passing through the second sensor unit 14 while the gate unit 30 is performing the lowering operation. The time for determination is set.
Basically, the operator manually operates the timer means 103 to set a desired time interval, and the time interval naturally needs to be changed as appropriate according to the season. .
In other words, in the winter season when obstacles such as snow are a concern, the time interval is set to be short, while in summer, there is no such concern, so it may be set longer. is necessary.

The timer means 103 is manually operated by an operator to set a desired time interval, but it is also possible to automatically set the time interval using an appropriate program. Needless to say.
Further, the data calculation control means (CPU) 213 is a computer means for executing appropriate data calculation processing, and its configuration and performance are not particularly limited, and a general computer can be used. .

On the other hand, the first storage means 214 connected to the data calculation control means (CPU) 213 is a control program for driving the entire opening / closing control system of the lift gate according to the present invention, for example, the gate section. 30 stores the program for executing the opening / closing processing operation of 30 and the reference operation data regarding the operation of the gate unit 30, and identifies the difference between the operation status and the reference operation related to the gate unit 30, which will be described later, An operation processing program or the like for determining whether the operation of the unit 30 is normal or abnormal is incorporated, while the second storage unit 215 has an operation status regarding the gate unit 30. Are sequentially recorded and stored.

Further, the monitor means 202 used in the present invention is composed of appropriate image information display means, and is attached to the back side of the open / close door 201 in the control box 200. Desirably, for example, it is also a preferable specific example that the monitor unit 202 is activated when the door 201 is opened.
Then, the monitoring unit 202 collects various data relating to the current and past operation operating states of the gate unit 30 stored in the second storage unit in a desired format, as appropriate, or It is configured to display in response to an instruction from a member.

If a specific example of the position of the opening / closing operation and the inspection / repair operation of the gate portion 30 in the opening / closing control system 100 of the lift gate according to the present invention will be described, first, it is arranged in a desired area. For example, when a request from the road management company to open the gate section 30 of the gate body section 3 is opened, the worker in charge goes to the position where the gate body section 3 exists. First, an operation of opening the gate unit 30 is performed by operating the remote controller.
At that time, when the gate unit 30 is opened without any problem or when the subsequent closing operation of the gate unit 30 is performed without any problem, the opening / closing gate opening / closing control system 100 has a functional problem. In this case, it is desirable that the worker in charge should open and inspect the control unit (control box) 200 provided in the vicinity of the gate body 3. .

At that time, the monitoring means 202 is checked to check the operating status of the gate unit 30 in the past, and although the opening / closing operation of the gate unit 30 has not stopped in the past, It is desirable to investigate whether or not a situation that would result in a failure reserve army had occurred.
Of course, as a result of the actual operation, when the gate unit 30 does not operate at all, or when a situation occurs such that the operation is temporarily stopped after being started, the same The monitoring unit 202 is checked to determine what causes the gate unit 30 is in an inoperative state, and the operation status of the gate unit 30 in the past is also checked to check the gate unit At the same time as identifying the cause of the 30 failures, immediately contact the department responsible for the failure and the policy for repairing the failure, etc. to the repair work department, such as telephone, fax or mail, etc. To arrange through.

Such a series of operations can be similarly performed in the remote control unit 300 provided in a remote place different from the site where the gate body 3 is arranged.
That is, the remote control unit 300 according to the present invention is joined to the control unit 200 provided at the site where the gate main body unit 3 is installed through an appropriate means such as wired or wireless. Communication between the two is sufficiently ensured.

By the way, the control means provided in the remote control unit 300 includes, for example, as shown in FIG. 7, a wireless signal receiving / transmitting means 301, a monitor means 302, a reset means 303, a seasonal mode switching means 309, Manual gate body opening / closing means 304, box internal temperature adjustment switch means 310, box internal temperature adjustment means 305, image display means 306 from the monitoring camera, location selection means 307 for the gate main body 3, and gate main body warning Display means 308 and the like are provided.
If the configuration of the control means provided in the remote control unit 300 will be described in more detail, the operation of the open / close control system for the lift gate, which is located at a remote location away from the installation site of the lift gate, will be described. In the remote control unit that executes the operation, the current and past operations of the lift gate transmitted from the open / close control unit of the lift gate arranged adjacent to the installation site of the lift gate Receiving means for receiving information on the situation, third storage means for storing information on the current and / or past operating situation of the specific lift gate for each specific lift gate, the third storage Operating status information display means for displaying, for each specific lift gate, information on the current and / or past operating status of the specific lift gate from the information stored in the means A temperature controller control means for adjusting at least the temperature in the control section, a timer control means, a reset means, a vertical movement drive switch means for the lift gate, which are disposed in the control section disposed at the installation site of the respective lift gates, The operation information of the individual control switch units and the individual control switch units that can be remotely operated individually, such as the season switching unit, the temperature adjustment switching switch unit in the control unit, are arranged at the installation site of the individual lift gates It is a preferable example that the control switch part operation information transmission part transmitted with respect to the control part is provided.

As the monitoring operation of the worker in the remote location control unit 300, for example, first, the worker operates the arrangement location selecting means 307 of the gate main body unit 3 so that the predetermined gate main body unit 3 is operated. Calling a predetermined area, the past and current operating status of the gate portion 30 of the gate main body 3 at the predetermined location via the screen of the monitoring means 202 is displayed. You can check it.

Further, the environmental condition around the predetermined gate body 3 can be confirmed while viewing the image transmitted from the monitoring camera 215.
Such an operation is not limited to the case where the worker himself checks the operating status of the gate body 3 in the desired area, but an ambulance that urgently carries a traffic accident victim from a highway repair company or fire department. Even if there is an emergency request for opening the gate part 30 of the gate body part 3 in a predetermined area from the remote control part 300, the manual gate body part opening / closing means 304 is By operating, it becomes possible to remotely open the desired gate portion 30 of the gate main body portion 3.
Again, as described above, the main object of the present invention is to maintain the gate portion 30 of the gate main body portion 3 in a completely movable state at all times, and to immediately and accurately respond to the emergency opening request. It can be realized only by practicing maintenance and management so that the opening and closing operations can be realized.

In addition, in response to seasonal changes, the mode change for each season, the adjustment of the timer setting time in the timer means 103, and the temperature adjustment operation in the control box 200 at the site are also performed by the remote control unit. It can be easily executed by operating the key operation of the desired operation means while referring to the display information of the monitor means 302 of 300 and the peripheral information obtained from the monitoring camera.

Furthermore, in the present invention, whether the operation related to each gate unit 30 is normal from the current and past operation status data of the gate unit 30 in the gate main body unit 3 in the field, Warning information indicating that an inoperable state or an inoperable state is likely to occur is determined via an appropriate arithmetic program used for the arithmetic processing means, and the result is determined as the remote control unit 300. The information is displayed on the gate main body warning display means 308 and the information is displayed on the monitor means 200 in the control box 200 which is the control means in which the gate main body part 3 is arranged. Even in this case, the problem can be confirmed.

Next, the maximum and most important opening / closing operation of the gate portion 30 in the gate body portion 3 in the lifting gate opening / closing control system 100 according to the present invention is absolutely in a defective state. The basic technical configuration related to the operation method and operation program for the maintenance management operation so as not to cause the opening / closing operation to be inoperative will be described in detail.
That is, the basic technical configuration in the operation method and operation program for the maintenance operation in the present invention is a characteristic operation element related to the opening / closing operation of the gate portion 30 in the gate main body portion 3. Each time an opening / closing operation of the gate unit 30 is performed, characteristic parameters of the operation element are measured, and the parameter data is used as the operation occurrence date / time information of the gate unit 30 and the operation occurrence time. The information is stored in an appropriate memory means together with the information, and at the same time, the stored parameter data is compared with standard reference value data set in advance, for example, the difference or ratio between the two is calculated. If the result is 0 or within a preset allowable error range, it is determined that the opening / closing operation of the gate unit 30 is in a normal state, while the difference value or When the ratio or the like exceeds the preset allowable error range, the opening / closing operation of the gate unit 30 is in a state where a defective state due to some cause has occurred or a defective state can be easily caused. It is to be judged.

At the same time, by grasping the situation such as the occurrence frequency, the number of occurrences or the number of consecutive occurrences of the defective state in the operation, and predicting in advance the state in which the opening / closing operation of the gate unit 30 is inoperative In advance, it is possible to prepare a repair / repair schedule in advance, which part of the gate main body 3 should be repaired / repaired at what point in time. This information can be notified in advance.
Of course, in the present invention, when the gate portion 30 does not perform the opening / closing operation in spite of commanding the opening / closing operation of the gate portion 30 in the gate main body portion 3, the gate portion 30 is Needless to say, it is determined that a failure has occurred.
In the present invention, all the information and data related to the operation status related to the opening / closing operation of the gate unit 30 are stored and stored in the second storage unit 214.

Furthermore, in the present invention, in the situation where the opening / closing operation of the gate unit 30 has been disabled from the beginning, the monitoring unit 202 or 302 similarly records the opening / closing operation of the gate unit 30 in the past. By displaying the above and analyzing what kind of defective state has occurred in the past with respect to the opening and closing operation of the gate part 30, how to repair and repair which part of the gate body part 3 It is possible to accurately notify the maintenance worker of information on what should be done and to perform quick, accurate and appropriate repair work.
In addition, standard reference value data set in advance relating to the operation parameter data described above is also stored in the second storage means 214.

On the other hand, the program for executing the drive control of the gate section 30 and the comparison calculation processing program for the reference value data for the operation parameter are stored in the first storage unit 215. Things are desirable.

On the other hand, as yet another specific example of the opening / closing control system 100 for the lift gate according to the present invention, the person in charge of the opening / closing control system for the lift gate determines the cause of the abnormality displayed on the monitor unit of the control means. After confirming, first, the reset switch provided in the control means is operated directly or remotely, and if the abnormal state cannot be recovered, human repair work is performed. Needless to say, it may be configured.

In the following, as the operation parameter related to the opening / closing operation of the gate part 30 in the lifting gate opening / closing control system 100 according to the present invention, the time for the gate part 30 to pass between the sensor parts is adopted. Is measured every time the operation is performed, stored in an appropriate storage means, the measured parameter data is compared with the reference value parameter, and if the comparison result is within a predetermined tolerance, it is normal. If the result is other than the permissible value, it is determined that the situation is abnormal, and from the result, the normal state of the opening / closing operation status of the gate section 30 in the gate main body section 3 and / or An example of a specific procedure for finding an abnormal situation and, when necessary, utilizing it for a practical processing operation of appropriate repair and maintenance will be described.

Further, regarding the opening / closing operation of the gate part 30 in the opening / closing gate opening / closing control system 100 according to the present invention, when the gate part 30 does not operate from the beginning, or the gate part 30 was initially driven, If the operation stops during the one-cycle count, it is determined that an abnormal situation has occurred, and repair / repair operations are immediately executed.
In the specific example of the present invention, the first sensor means 13 is referred to as “upper stop sensor means 13” and the second sensor means 14 is referred to as “lower stop sensor means 14”. The third sensor means 12 will be referred to as “upper deceleration sensor means 12”, and the fourth sensor means 15 will be referred to as “lower deceleration sensor means 15”.

In this specific example, between the upper deceleration sensor means 12 and the lower deceleration sensor means 15, the gate portion 30 is slid in the vertical direction at a first speed at a high speed level. On the other hand, between the upper deceleration sensor means 12 and the upper stop sensor means 13 and between the lower deceleration sensor means 15 and the lower stop sensor means 14, the gate part 30 is at the high speed level. It is assumed that the slider slides in the vertical direction at the second speed slower than the speed of 1.

Four types of transit time (down deceleration / up stop) are adopted as parameters.

Furthermore, in this specific example, after the gate portion 30 in the gate main body portion 3 once rises from the lower end stop position to a predetermined uppermost position, it returns to the original lower end stop position for one cycle. The driving process is counted as one count.
When the gate unit 30 in the gate body 3 is driven, the date, the drive start time, the drive end time, and the weather conditions of the area are recorded as necessary. At the same time, the distinction as to whether the drive command has been made manually or by remote operation means including remote control means is also recorded.

Here, an example of a specific procedure when the opening / closing gate opening / closing control system 100 according to the present invention is implemented will be described with reference to the drawings.
First, when starting up the system, for example, when the door 201 of the control box 200 is opened, the system is turned on, and a display as shown in FIG. 8 is displayed on the monitor means 202 provided on the inner surface of the door. Is displayed on the screen, and in the opening / closing control system 100 for the lift gate as shown in FIG. 9, the gate in the basic gate body 3 currently set in the control software is displayed. The driving conditions of the unit 30 are displayed.
For example, it is desirable to display the drive mode, timer set time, first speed, second speed, and the like.

When the open / close gate opening / closing control system 100 according to the present invention is operated, each data described above is recorded during the operation, and at the same time, a comparison with the reference data value described above is executed. When the operation of the cycle is completed, a data table as shown in FIG. 10 is created and stored in the second storage unit 214.
As will be described later, this table can be arbitrarily displayed on the monitor means 202 by the maintenance manager of the opening / closing control system 100 for the lift gate as required.
That is, FIG. 10 shows an example of data that should be stored at the minimum when the opening / closing operation of the gate unit 30 is executed at the time of one activation in the specific example according to the present invention. Is.
In FIG. 10, the reference value data to be compared with each actual measurement data is, for example, stored in advance in the first storage means 215 as described above.
In FIG. 10, for example, the location of the gate body 3 and its identification number, the recorded date and time, the time T1 when the gate 30 started to operate, and the gate 30 ended. Distinction between manual operation and remote operation including remote control, passage time X1 of (lower stop / upper deceleration), passage time X2 of (lower stop / upper stop), (lower deceleration / upper deceleration) The passage time X3 and the passage time X4 of (lower deceleration / upper stop), the comparison value (difference value Xn−X0) ΔX with the reference value parameter X0, the determination result, and the like are shown.

In this specific example, the passage time X1 of (lower stop / upper deceleration), the passage time X2 of (lower stop / upper stop), the passage time X3 of (lower deceleration / upper deceleration), and (lower deceleration / upper deceleration) Stop) transit time X4, comparison value (difference value Xn−X0) ΔX with reference value parameter X0, and each data related to the determination result are the data when the gate unit 30 is rising and when the gate unit 30 is falling It is a more preferable specific example to measure the data in half and display the result.
Further, FIG. 11A shows a situation in which the gate unit 30 does not operate from the beginning despite the start instruction in the system 100 being recorded in this specific example. Specifically, when the gate unit 30 is inoperative, first, the reset switch 208 is operated to try to drive the gate unit 30. If the gate unit 30 is successful, the driving operation of the gate unit 30 is continued as it is. Measure the transit time data for each site and record the date and time of recovery.
In this case, the operation evaluation of each part is displayed as “non-normal”.

On the other hand, if the driving of the gate unit 30 is not started even when the reset switch 208 is operated, then the manual operation switch 210 is operated. The driving operation of the unit 30 is continued, the passing time data of each part described above is measured, and the date and time of recovery are recorded.
In this case, the operation evaluation of each part is also displayed as “non-normal”.
On the other hand, if the driving of the gate unit 30 is not started even when the manual switch 210 is operated, the display of “abnormal” is recorded, and at the same time, the management / maintenance worker is informed of the gate main unit 3 At the same time that the gate unit 30 is notified of the failure, a command to immediately repair the gate unit 30 is transmitted.
In this case, in FIG. 11B, the passage time X1 of (lower stop / upper deceleration) described above in FIG. 10, the passage time X2 of (lower stop / upper deceleration), and (lower deceleration / upper deceleration). The passage time X3 of () and the passage time X4 of (lower deceleration / upper stop) are both displayed as unmeasurable, and “abnormal” is displayed in the determination result column.

That is, when the gate unit 30 is inoperative, first, the reset switch 208 is operated to try to drive the gate unit 30, and if successful, the driving operation of the gate unit 30 is continued as it is. If the driving of the gate unit 30 is not started even when the reset switch 208 is operated, the manual operation switch 210 is operated, and when the driving is started thereby, the driving operation of the gate unit 30 is performed as it is. On the other hand, if the driving of the gate unit 30 is not started even when the manual switch 210 is operated, the display of “abnormal” is recorded, and at the same time, the gate body unit At the same time, it is notified that the corresponding three gate portions 30 are out of order, and at the same time, a command to immediately repair the corresponding gate portion 30 is transmitted.

On the other hand, FIG. 12 shows that in this specific example, the gate unit 30 was operating normally immediately after issuing the activation instruction in the system 100, but at any time at any part. The situation when the gate unit 30 stops its operation is recorded. For example, the passage time X6 corresponding to the passage time X1 (lower stop / upper deceleration) in FIG. X7 corresponding to the passage time of (bottom stop / up stop) can measure the data, and if the comparison with the reference value is within the allowable range, the evaluation data of both is displayed as “normal” However, the passage time of (lower deceleration / upper deceleration) and the passage time of (lower deceleration / upper deceleration) are both displayed as unmeasurable because the gate unit 30 has stopped moving. “Abnormal” will be displayed.

In such a specific example, it can be presumed that the operation of the gate section 30 has stopped in the area of (upper deceleration / upper stop).
However, there are cases where the gate unit 30 does not reach a fully open state or does not reach a completely closed state. In a specific example, it is desirable to operate 210 to forcibly shift the gate unit 30 to a predetermined position.
Even in this case, when the gate unit 30 that has fallen into the inoperative state is restored by a manual switch, it is desirable to record the date and time of restoration.
In the present invention, various data as described above from the past to the present are stored and saved in the second storage means 214.

Next, an outline of a program for executing management / maintenance of the lifting gate opening / closing control system 100 according to the present invention will be described.
First, when the person in charge of management / maintenance of the system 100 selects abnormality monitoring / maintenance on the screen of FIG. 8, a screen as shown in FIG. 13 is displayed on the monitoring means 202, and thereafter from the past to the present. In the operation status data of the gate unit 30, all the data displayed as “non-normal” are listed and displayed in time series on the monitor unit 202 as shown in FIG. Will be done.
Such data is desirably displayed in a classified manner based on the identification data of the gate body 3, and the person in charge of the management / maintenance inputs the identification data to specify the specific gate body. It is also possible to display management data of only the section 3.
Examples of display data in FIG. 14 include, for example, location, operation layer time, total number of activations, date and time of occurrence of abnormal state, operation mode, timer setting time, distinction between manual operation and remote operation, and the abnormal state The generation site, passage time, comparison data with reference values, evaluation data, and the like are included.

On the other hand, when an abnormal state occurs in which the gate unit 30 does not respond to the activation instruction and is in an inoperative state, first, the reset switch 208 is operated to attempt recovery, and driving is started. In this case, if the operation of the gate unit 30 is continued as it is and the driving of the gate unit 30 is not started even when the reset switch 208 is operated, As shown in FIG. 15, for example, data such as location, operation layer time, total number of activations, date and time of occurrence of abnormal condition, operation mode, timer setting time, distinction between manual operation and remote operation, and recovery completion date and time are included. .

Further, in the system 100 according to the present invention, when it is said that the abnormal state has occurred, for example, five times in total from the past in the same gate portion 30, the gate body portion 3 It is desirable to display an alarm on the monitor means 202 that it is necessary to immediately execute the radical modification and repair of the whole. When it is said that such an abnormal state has occurred, for example, five times, the gate unit 30 Therefore, it is determined that there is a high possibility that some kind of failure will occur in the near future. For example, as shown in FIG. 16, repair and repair of the gate part 30 are performed as soon as possible. It is a specific example in which it is desirable to display an alarm that needs to be executed on the monitoring means 202.

On the other hand, in the case of YES in step 20 (ST20), that is, when the gate unit 30 becomes inoperative during the operation, various reasons can be considered, but the process proceeds to step 29 (ST29). Attempting to re-drive the operation of the gate unit 30 using the reset unit 208, and in step 30 (ST30), it is determined whether or not the unit gate unit 30 has started driving again. Then, the process proceeds to step 31 (ST31), and data relating to the drive parameter is measured. In step 32 (ST32), the measured drive parameter data is compared with the parameter data reference value to obtain predetermined evaluation data. Calculate.

However, in this specific example, even if the evaluation obtained in this step is evaluated as “normal”, an abnormal state has already existed in the drive state. In ST33), the evaluation is "non-normal", and the result and the date on which the "non-normal" state occurs are stored in the second storage means 214 in step 35 (ST35). Stored.
Thereafter, the process proceeds to step 36 (ST36), where it is determined whether or not the number determined as “unnormal” in the operation history of the gate unit 30 is, for example, five or more. 26 (ST26).

If so, the opening / closing operation is END.
If NO in step 30 (ST30), the process proceeds to step 40 (ST40), the manual switch means 210 is operated to try to start the operation of the gate unit 30, and step 41 (ST41). Then, it is determined whether or not the opening / closing operation of the gate section 30 has been started. If YES, the process returns to step 31 (ST31) and the subsequent processes are continued. However, in step 41 (ST41) If NO, the process proceeds to step 42 (ST42), where the display of "abnormal" indicating that the gate unit 30 is out of order is displayed on the monitoring means 202, and at the same time the abnormal state has occurred.
