Description

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

  Vehicles for road construction, traffic accident-treated vehicles, fire extinguishing vehicles, vehicles for handling accident-impaired people, work vehicles such as snow removal vehicles, etc. An emergency approach route or emergency exit route is provided to allow direct access to the inside of the expressway, or to get off the expressway onto a general road along the road, and the emergency entrance route or exit of the emergency exit route is Normally, a general worker is closed by a gate or the like so that they can not enter or leave, and when it is necessary to pass the predetermined vehicle, a predetermined worker performs remote control operation at the installation site of the gate, Alternatively, the appropriate control means disposed at the installation site of the gate is operated to operate the gate such as opening or closing to open the entrance of the gate, and after the vehicle passes, Work to say that returning the over door in the closed state is running.

  In the prior art, the gate installed at the entrance of the emergency access path is conventionally unwound from a winding drum as shown in, for example, Japanese Patent Laid-Open No. 2008-291528 (Patent Document 1) and suspended from above. The gate body suspended by the wire rod is arranged to be able to move up and down at the entrance and exit, and the winding drum is turned to wind up the wire body to lift the gate body and open the entrance and vice versa Generally, the gate main body is lowered by unwinding the wire, and the entrance of the gate main body is closed.

In the conventional wire lifting type lifting gate, the wire 32 for hanging the gate body 33 is always pulled down and stretched due to the weight of the gate body 33, but as shown in FIG. When an obstacle 38 such as snow deposited on a descending trajectory of the body 33 or a snow lump generated by snow removal is present on the descending trajectory, the gate body 33 abuts on the obstacle 38 and the gate body There was a frequent problem that it would stop halfway before it had fallen 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 the wire 32 of a predetermined amount is unwound, so only the unwound wire 32 The wire 32 slackens, and the wire 32 slackens, and the wire 32 wound around the take-up drum 31 spreads outward irregularly in a regular alignment state, and the wire 32 in this irregular state When the coil is wound up, it becomes wounded, causing catching and entanglement of the wires 32 and causing a failure such as an operation failure of the winding drum 31.

  Therefore, in order to solve such conventional problems, for example, as shown in Japanese Patent No. 5178945 (Patent Document 2), the wire is unwound from the winding drum 1 and suspended by the wire rod 2 suspended from above. The gate main body 3 provided is movably disposed at the entrance 5 of the entrance / exit gate 4, and the winding drum 1 is rotated to wind the wire 2 up to raise the gate main body 3. In the wire lifting type lifting gate configured to lower the gate main body 3 and close the entrance / exit 5 by unwinding the wire 2, the wire 2 is connected to the wire 2. There is provided a retaining locking portion 6 which is locked to the gate main body 3 when it is taken up and lifted and lifted the gate main body 3 and the retaining locking portion 6 is the gate main body by winding the wire 2. Lock to 3 By further winding up the wire 2 in a state in which the retaining locking portion 6 is locked to the gate body 3, the gate body 3 is configured to be lifted and lifted, and the hanging wire 2 is made to have a weight 7. To pull down the wire 2 by the weight 7 and unwind the wire 2 in a state in which the retaining locking portion 6 is retained and locked to the gate body 3 and the gate is provided. When the main body 3 is lowered, the weight 7 can be taken up by the winding drum even if the stopping or lowering speed of the gate main body 3 is lowered during the lowering by the obstacle 8 present on the descending trajectory of the gate main body 3 By configuring so that slack does not occur in the wire rod 2 by moving down with the unwinding amount of 1, even if the gate main body is stopped on the way down by the obstacle existing on the lowering track, this gate Body Set to turbulent wound without slack wire rod has is been to provide excellent wire hoisting lift gate practicality does not occur.

  However, as a more important issue in the control of the opening and closing of the elevator gate, the elevator gate is always a vehicle with high urgency such as an emergency road repair vehicle as described above, a fire engine, an ambulance, a police vehicle, etc. It is extremely important that the destination be reached safely, quickly, accurately and reliably, so that the switching device of the elevator gate is absolutely and always free of faults, anytime, switching operation It is important to be managed and maintained in such a way as to ensure that

Temporarily, when a part of a certain expressway is provided with a formal vehicle approach or exit route, the road area in the middle of the place where the official vehicle approach or exit route is provided In the situation where there is no further formal vehicle approach or exit route, there is still another emergency approach or emergency exit route between them. For example, in the case where an emergency hospital related to neurosurgery is present near the emergency approach route or emergency exit route, the road area in the middle of the place where the official vehicle approach route or vehicle exit route is provided In the case where an automobile accident occurs and an accident injured person is transported to the emergency hospital using an ambulance that happened to pass the accident site of the expressway, the emergency close to the accident site Of the vehicle The gate is opened by a worker at the site or a worker at the remote control section at a remote location, and the ambulance is pulled down the expressway via the emergency exit route. It becomes possible to transport the injured person to the emergency hospital in a short time and efficiently to the emergency hospital.

However, if the gate opening and closing device of the emergency exit road breaks down and the gate can not be opened, the ambulance goes to the place where the official vehicle exit path is provided and goes around As a result, they go to the emergency hospital, which takes extra time and money, and there is a further risk that they will end up losing their lives.
Similarly, even when the gate can not be used and closed, it is not necessary to prevent the entry of suspicious vehicles, the occurrence of illegally entering vehicles, and the entry of animals etc. Needless to say, it is necessary to have an awareness of the problem.

Such an example is just one example of the gate apparatus according to the present invention, but it is essential that the gate provided in the emergency vehicle approach or emergency vehicle exit route is always normal in any environment. In order to operate properly, it is necessary to be maintained, and even in the event of some malfunction, a severe operation and maintenance operation that must never be done is always required.
However, there have been few studies for solving the above-mentioned problems, including the above-mentioned known examples, and an important solution is how to construct a detection system and a monitoring system therefor. It has been recognized as an issue.

In the state (A2), at a position (A3) spaced apart from the existing position of the gate portion 30 by a desired distance preset in advance, a specific portion in the gate portion 30 preset is The moving speed of the gate unit 30 when the gate unit 30 is moving, at a position lower than a position where the second sensor unit (lower stop position detection unit) 14 having a detecting function and the first sensor unit 13 are disposed. A third sensor unit (upper deceleration) for detecting the specific part of the gate unit 30 provided at a part where it is necessary to decelerate the speed of the gate unit 30 when The detection speed of the gate unit 30 when the detection unit 12 and the second sensor unit 14 are located above the third sensor unit 12 at a desired position above the third sensor unit 12. Slow down or The fourth sensor unit (lower deceleration detection unit) 15 for detecting the specific part of the gate part 30 provided at a part where it is necessary to accelerate the moving speed of the lifting part 30 when rising. The second sensor unit 14 is provided with timer means 103 at the same time as the second sensor unit 14 is provided, and the second sensor unit 14 detects the passage of the specific part of the gate unit 3. After that, the descent operation of the gate unit 3 is stopped after the time arbitrarily set by the timer unit 103 has elapsed, the opening / closing control system 100 of the elevating gate is shown. ing.

The configuration of the gate main body 3 used in the opening / closing control system 100 of the elevation gate according to the present invention is not particularly limited, but as a general configuration, it is as illustrated in FIG. And at least two pairs of support members 25 having a desired height, which are vertically arranged in parallel with each other with a desired distance from each other, and tension between the support members 25 A frame portion of a structure configured of one connection beam portion 16 disposed and the upper end edge frame portion 18 and the lower end edge frame portion 18 'left and right end edge frames provided inside the frame portion The gate portion 30 in which a plurality of rod-like reinforcing rod-like members 19 are arranged in the longitudinal direction inside the frame portion constituted by the portions 17 and 17 ′ is along the surface of the column member 25 or It slides along the internal space portions 120 and 121 of the support 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 any one of the gate 30 and the movable member 26 according to the present invention, whereby the gate 30 is vertically suspended with respect to the wire 2. A simple and inexpensive example of the gate main body 3 is configured to be driven in the direction.
The constituent material of the gate main body 3 in the present invention is not particularly limited either, but it is a preferred embodiment to be made of a rigid metallic material including, for example, an iron material or an aluminum material. .
Further, the dimensions of the height, width, etc. of the gate body 3 in the present invention are not particularly limited. For example, considering that the height of the snowplow in recent years has become high, The height of the support member 25 may be 10 m or more, and the width thereof is preferably a width covering at least two lanes.
Further, the height of the gate portion 30 is preferably 1 m to 2 m.

On the other hand, as a drive system for sliding the gate unit 30 in the gate main body 3 according to the present invention up and down, a chain type, spiral spiral screw type, hydraulic type, etc. can be used, but in particular In cold regions in snowy countries, there are problems such as temperature effects and freezing of snow, so using metal wire 2 and utilizing a rotary drive mainly composed of an electric motor, the wire 2 It is the most preferred embodiment to employ a system for unwinding and winding.

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

In the present invention, the stationary position A2 below the gate unit 30 in the gate main unit 3 simultaneously 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 where it is in direct contact with the surface of the road, but if there is snowfall in winter, the snow that has accumulated on the road surface due to the snowfall will be removed as a result of snow removal. If snow remains deposited on both sides of the road, and snow accumulation portion 8 is formed also on the base portion of the gate body 3 according to the present invention, that portion interferes with the downward movement of the gate portion 30, In many cases, the descent operation of the gate unit 30 must be ended with the lower end edge 18 'of the gate unit 30 not completely contacting the road surface.

If such a condition is left as it is, excessive load or impact is applied to each member and device of the gate main body 3, and damage and failure of the device frequently occur, and the above-mentioned snow cover If the height of the deposition part 8 due to the left and right is different on the left and right, the upper end edge 18 and the lower end edge 18 'of the gate part 30 can not maintain a perfect horizontal position, and the pair of columns Between the members 25, there is also a situation where it is in an oblique state and vertical movement is not possible.
It goes without saying that the repair work in that case is a considerably troublesome task.
Therefore, in the present invention, the stationary position A2 below the gate 30 is set to a position where the lower end edge 18 'of the gate 30 is in direct contact with the surface of the road. Instead, it is set so that a certain amount of space can be formed between the lower end edge 18 'of the gate 30 and the surface of the road.
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 end edge 18 'of the gate 30 in the present invention is not particularly limited, but the land environment in which the gate body 3 is installed It is possible to set as appropriate in consideration of the weather environment, seasonal factors, the moving speed of the gate unit 30, and the like.
In the present invention, in a situation where the desired space portion is forcedly provided, the temporary rest position A2 below the gate portion 30 is determined, and the gate portion 30 is moved from the temporary rest position A2. Further, the descent is continued to finally be stopped at the desired lower position.

Specifically, for example, in the desired area where the gate main body portion 3 is set, the height of the deposition portion 8 described above is 50 cm on average from the ground surface by the snow removal operation at the time of snowfall If it is estimated that the height of the space between the surface of the road and the lower end edge 18 'of the gate 30 is, for example, 60 cm to 70 cm below the gate 30 The temporary stationary position A2 is
In the present invention, when the gate unit 30 performs the lowering operation, it does not stop the lowering operation after the gate unit 30 passes the position of the temporary rest position A2. The gate portion 30 is lowered to a position substantially in contact with the upper surface portion of the deposition portion 8, and control is performed so as to stop the lowering operation there.

Specifically, if the descent 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 descent speed. It is possible to execute easily by doing.
That is, in the present invention, due to a seasonal factor or a geographical factor, the timer unit 103 continues the descent operation of the gate unit 30 after passing through the temporary resting position A2. By setting the time appropriately, it is possible to be more realistic and to minimize the risk of occurrence of failure or damage.

Limitation or adjustment of the rotational drive time of the drive means 1 in the timer means 103 can be arbitrarily set by manual operation by the operator, or a medium such as wireless, infrared, light or the like is used It is also a desirable embodiment to be able to set the timer drive time automatically from a remote place without contact.
Furthermore, it may be configured to automatically change the timer setting time by using an appropriate program.

In this case, a space is generated between the lower end edge 18 'of the gate 30 and the road surface, and various animals may intrude into the expressway from this part. A plurality of flat sheet-like flexible sheet members 23 made of fabric, rubber, synthetic resin material, etc. are attached in parallel from the lower end edge 18 'of the portion 30 to the lower surface, and the space portion It is also a desirable embodiment to be configured to close the.

In the above-mentioned specific example of the present invention, when the deposition unit 8 due to the snow does not exist, or when the deposit becomes low due to the passage of time, the set time of the timer is set. It is possible to cope by setting the length appropriately, and the maximum time corresponds to the fact that the lower end edge 18 'of the gate section 30 directly contacts 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 via an appropriate program in response to the season information. It is characterized by what is done.

Next, as shown in FIG. 2, in the gate main body 3 of the present invention, as shown in FIG. It may be configured to slide up and down according to the driving condition of the wire 2 in a state of being fitted in the appropriate slit portion 120 or the inner groove portion 121 provided, or as shown in FIG. In the same manner, at least a part of the both end portions of the gate portion 30 is fitted in the appropriate slit portion 120 or the inner groove portion 121 provided in the pair of column members 25 forming the pair, You may be comprised so that it may be engaged with the movable member 26 currently comprised so that it might slide up and down according to the drive condition of the wire 2, and it may slide up and down.

In the present invention, in the case where the gate portion 30 is moved by a specific distance in the vertical direction while sliding the gate portion 30 along each of the pair of support members 25, the end portion of the wire portion 2 is fixed. A suitable anti-friction means, for example, a sliding member, is applied to a portion of the gate portion 30 that is in contact with the slit portion 120 of the column member 25 or the inner wall portion of the recessed groove 121 of the column member 25. It is preferable that a means such as a rotating roller 122 is provided, and a part of the gate portion 30 is in the inside of the concave groove portion 121 having a H-shaped or U-shaped cross section of the column member 25. It may be configured to move in the up and down direction by engaging and fixing to the movable member 26 to which the end of the wire part 2 is fixed to move and slide for a specified distance in the up and down direction. , Even in this case, A part of the surface of the movable member 26 is in contact with the slit portion 120 of the column member 25 or the inner wall surface portion in the H-shaped or U-shaped recessed groove portion 121 of the column member 25. It is desirable that an appropriate anti-friction means, such as a sliding member, a rotating roller, etc. 122 be provided.

Furthermore, in the present invention, in particular, when the gate main body 3 disposed in an area where there is a large amount of snowfall in winter, for example, most members are made of iron material, the iron material is If the temperature drops, it tends to cool, so if a considerable amount of snow adheres to the gap between the slit 120 and the groove 121 of the column member 25 and deposits, that portion becomes frozen As a result, the vertical movement of the gate unit 30 is restricted or becomes inoperable.
In some cases, since a part of the gate unit 30 may be destroyed or damaged, the occurrence of such a condition needs to be always avoided.

Therefore, in the present invention, as shown in FIG. 4, a portion of the gate portion 30 or a portion of the movable member 26 sliding in the slit portion 120 or in the groove portion 121 is It is a preferred embodiment to attach at least one scraper portion 35 having a function capable of removing deposited snow and discharging it to the outside of the slit portion 120 or the groove portion 121.
In the specific example of the present invention, the material of the scraper portion 35 may be metal or a synthetic resin containing FRP.
Further, the number of the disposed scrapers 35 and the dimensions thereof are not specified, but may be set arbitrarily, but preferably, the tip end is formed in a blade state, and the cutting edge is the concerned cutting edge. It is desirable to attach the end edge portion of the slit portion 120 and the inner wall surface portion of the groove portion 121 so as to face each other with a gap of, for example, about 2 to 5 mm.

It goes without saying that the configuration is effective not only when snow is used, but also when earth and sand or small-grained rocks are deposited between the slit portions 120 or in the groove portion 121.
That is, the scraper portion 35 in the present invention is an inner wall surface portion of the pillar member 25 in at least a part of the movable member 26 sliding along the internal space portion 121 of the pillar member 25 or the gate portion 30. And the inner wall surface portion so as to be slidable while facing each other through a minute gap.

Next, in the present invention, as described above, the gate unit 30 winds the wire unit 2 between the pair of support members 25 of the gate body unit 3 using the driving unit 11. By taking out or unrolling, the sliding movement is made in the vertical direction along the longitudinal direction of the support member 25, but the gate portion 30 itself has a considerable weight, so at high speed. Since the drive control of the above is dangerous and directly causes the damage or failure as well, basically, it is desirable to drive the gate 30 up and down at a low speed.

The vertical movement driving speed of the gate unit 30 is not particularly limited, but may be set to, for example, about 5 cm to 15 cm per second (first speed).
That is, as still another aspect in the present invention, for example, the rising and lowering speeds of the gate unit 30 are basically the section between the third sensor unit 12 and the fourth sensor unit 15. In the high speed state, which is the first speed, and between the first sensor unit 13 and the third sensor unit 12 and the fourth sensor unit 15 and the second sensor unit 14. In the section between the two, the opening / closing control system of the lift gate is characterized by being set to a low speed state which is a second speed, and as a further different aspect, for example, the second A 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.

Further, in the present invention, the operation of stopping the heavy gate unit 30 at a predetermined place and the operation of starting the drive from the predetermined place also prevent the occurrence of a failure, the occurrence of breakage of members, and the like. From the necessity, it is desirable to operate accurately, safely and stably. Therefore, in the present invention, the operation for stopping the gate unit 30 at a predetermined place and the drive from the predetermined place are required. It is desirable that the operation to be started is driven in a slow and stable state at a speed (second speed) slower than the above-described first speed.
The vertical movement driving speed of the gate unit 30 is also not particularly limited. For example, the speed set at 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 position where the vertical movement driving speed of the gate unit 30 is reduced from the first speed to the second speed, or the timing thereof, and the vertical movement driving of the gate unit 30. There is no particular limitation on the location, timing, etc. in the case of increasing the speed from the second speed to the first speed, but at least the gate unit after the speed change is performed. It is desirable to provide a time interval which results in a stable effective drive speed before the vehicle 30 stops at a predetermined location or before reaching an acceleration location from the predetermined location.
The time interval in the present invention can be set, for example, to about 2 to 5 seconds under the above-mentioned speed setting condition.

In order to specifically realize the above technical concept, in the present invention, a specific arrangement position of the gate 30 in the gate main body 3 when moving up and down along the column member 25 is detected. In order to do this, it is one of the preferable embodiments to provide appropriate sensor means for detecting the existing positions of the plurality of gate parts 30 on the surface of the support 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 unit 30, and between the both stop positions A1 and A2, the upper stop position Movement of the gate section 30 set at a position A3 spaced apart from the A1 by a predetermined distance D1 and a position A4 spaced upward from the lower stop position A2 by a predetermined distance D2 It is desirable to provide appropriate sensor means 12 to 15 at each of the speed change operation parts.

That is, if the said technical structure in this invention is more concretely demonstrated, along the surface of at least one post member 25 of the said post member 25, or the vicinity part of the said one post member 25, The position of a specific portion in the gate section 30 set in advance is detected at the existing position of the gate section 30 in the state where the opening of the gate section 30 in the gate main body 3 is completed. The first sensor unit (upper stop position detection unit) 13 having a function and the lower end edge 18 'of the gate unit 30 in the gate main unit are in contact with or close to the road surface and the closing is completed In a state, at a position separated by a desired distance preset from the position where the gate section 30 is present, a function of detecting a preset specific part in the gate section 30 is provided. Of the sensor unit (lower stop position detection unit) 14 and the first sensor unit 13 at a position lower than desired, and the moving speed at the time of rising of the gate unit 30 is reduced or the gate unit is A third sensor unit (upper deceleration detection unit) 12 for detecting the specific part of the gate part provided at a part where it is necessary to accelerate the moving speed at the time of descent of 30; A desired upper part from the second sensor part 14 and a lower part than the third sensor part 12 to reduce the moving speed of the gate part 30 when it is lowered or to raise the gate part A fourth sensor unit (lower deceleration detection unit) 15 for detecting the specific part of the gate part 30 is provided at a part where it is necessary to accelerate the moving speed at the time of Is a desirable configuration

As a preferable specific example in the present invention, the second sensor unit 14 is provided with an appropriate timer means 103 as described above, and the second sensor unit 14 corresponds to the gate. After the passage of the specific part of the unit 30 is detected, the timer means 103 is operated, and after the time arbitrarily set by the timer means 103 elapses, the descent operation of the gate unit 30 is stopped. It is configured.
The structure, function or performance of each sensor unit used in the present invention is not particularly limited as long as it has a general sensor function conventionally used. Are also commonly used as proximity sensors such as sensors using light, sensors using infrared, sensors using electromagnetism, sensors using electric capacitance, sensors using sound including sound, etc. Sensor means are available.

Furthermore, in the present invention, each of the sensors detects a predetermined portion of the gate portion 30 and determines whether the gate portion 30 has reached the predetermined portion. However, for that purpose, it is desirable to attach an appropriate marker 125, for example, an appropriate magnet, a mirror, a concavo-convex part, a color imparting part, etc. to a part of the gate part 30 in advance.
Generally, the sensors 12 to 15 are the outer surface of the column member 25 or the inner wall surface of the inner groove 121 of the column member 25 and the edge of the gate 30 or the outer surface of the movable member 26. Since it is a specific example that is preferably attached to a portion facing the surface, the marker 125 corresponds to the height level of the upper end edge portion 101 of the gate portion 30, and is the end of the gate portion. Preferably, it is provided in the vicinity of the edge or in the vicinity of the edge corresponding to substantially the same height level as the upper edge 101 of the gate 30 in the movable member.

In the present invention, in place of the marker 125, another marker 126 is provided in the vicinity of the edge of the gate, which corresponds to substantially the same height level as the lower edge 102 of the gate 30. Things are also desirable examples.
In the present invention, although it is a preferred embodiment to use the marker alone at any site described above, in some cases, it is also preferable to use both the markers 125 and 126 described above in combination. It is a specific example.
Therefore, in another embodiment of the present invention, in the first and third sensors 13 and 12, the first marker 125 disposed near the upper end of the gate unit 30 is detected. While the second and fourth sensors 14 and 15 detect the second marker 126 disposed near the lower end of the gate unit 30. Are configured to operate.

Further, in the present invention, when the gate unit 30 is moved up to the uppermost position, there is a risk that the rising operation is not stopped due to an error or some failure, and the rising continues. As it is conceivable, it is also desirable to provide the stopper means 128 having the function of preventing the upward movement of the gate portion 30 and having a suitable structure in the vicinity immediately above the first sensor means 13.

Next, the gate unit 30 in the opening / closing control system 100 for the elevation gate according to the present invention responds to the drive operation of the drive means 11 comprising an appropriate electric motor as shown in FIG. It is engaged with one end of a suitable wire means 2 wound around a rotary drive 1 constituted by a proper rotary drum 1 that rotates arbitrarily in the reverse direction, and the forward and reverse of the rotary drum It is made to slide up and down by the said wire means 2 wound up or unwound with rotation.
The wire routing method of the wire 2 disposed between the rotary drum 1 and the gate unit 30 at that time is not particularly specified, and any wire routing method of the wire means 2 is adopted, The method of drawing the wire means 2 shown in FIG. 1 is also a preferred embodiment.

Further, in the present invention, it is a preferred embodiment that the drive means 11 executes necessary operations such as the rotation direction and the number of rotations by using an appropriate inverter means. In the present invention, the gate unit 30 is a movable member having a considerable weight, and in particular, in the step of lowering the gate unit 30, a considerable load load is concerned via the wire means 2. If such a situation occurs, there is a risk that the electric motor will be excessively rotated and the gate part 30 may be suddenly dropped due to its weight. Then, not only damage of the gate part 30 but also various members and various means in the opening and closing control system of the elevation gate according to the present invention are destroyed and damaged.
Therefore, in the present invention, when at least the gate portion 3 performs the lowering operation, the rotary drive means 11 causes the rotary drive means 11 to perform regenerative braking via the appropriate brake resistor means 129. It is also a preferred embodiment that it is configured to apply a function.

In the present invention, for example, a high-frequency general-purpose inverter (FR-D700) manufactured by Mitsubishi Electric Corporation with a built-in or external brake resistor utilizing a regenerative resistance function is used as the inverter. Things are also possible.
That is, as still another specific example in the present invention, the rotational drive means 11 is configured to be capable of rotating in the forward and reverse directions by the electric motor mechanism, and at least when the gate portion 30 performs the lowering operation. Is an opening / closing control system of the elevation gate characterized in that the rotation driving means 11 is configured to exhibit a regenerative braking function via an appropriate brake resistor means 120.

Further, as another specific example in the opening / closing control system 100 of the elevation gate according to the present invention, the time setting of the timer means is manually or in response to the season information, manually or via an appropriate program. It is desirable to be configured to be able to adjust automatically by direct or remote control.
On the other hand, as still another specific example in the opening / closing control system 100 of the elevation gate in the present invention, the drive means is an appropriate control means connected to the storage means incorporating the appropriate program. It is also a preferable specific example that it is configured to be driven and controlled via the same.

The basic control processing operation in the opening and closing control system 100 for the elevation gate according to the present invention is close to the gate body 3 at the site where the gate body 3 constituting the elevation gate is disposed. 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, the power supply means 204 with a breaker in the box part having the door part 201 attached openably and closably, the inverter means 203, wireless signal transmission / reception means 205, timer means 103, reset means 208, brake resistance means 129 connected with inverter means 203, preferably with heat dissipation means added, seasonal mode switching means 209, manual gate main unit opening / closing Means 210, In-box temperature adjustment switch means 211, In-box temperature adjustment means 212, data calculation control means (CPU) 213, first storage means 215 incorporating control software, and the corresponding gate portion in the gate main body 3 In order to detect the operating status of 30 and store the result The second storage means 214, the monitor means 202 provided in the door part 201 of the box 200 and configured to be activated when the door part 201 is opened, and further, the system 100 The system start means 400 etc. which control starting are provided.

In addition, in the present invention, it is a preferable embodiment that a monitoring camera means 215 which is configured separately from the control box 200 is provided.
The main role of the monitoring camera means 215 is to control the state of the ground surface, particularly when the gate unit 30 in the gate main body 3 approaches the ground surface. Analyze the situation by accurately transmitting the actual situation to the manager in the control unit, and making an early prediction of the occurrence time and cause of the failure and the inoperative condition and the occurrence of the failure and the inoperative condition. It is important to be able to take urgent and qualified repair and repair processing quickly.

Furthermore, in the present invention, when the lift gate 30 is lowered to a position close to the ground surface in the vicinity of the installation site of the gate unit 30 which is the lift gate, the ground surface and its upper portion The monitoring camera 215 for monitoring the environmental conditions in the vicinity including the above is installed, and the monitoring image captured by the monitoring camera 215 is transmitted to the control unit 300 at a remote place different from the installation site of the elevating gate 30 It is a desirable specific example that the monitor image can be displayed on the operation status information display means 302.
In the case where a worker or a manager performs an operation of opening or closing the gate unit 30 in the gate main body 3 at the site, when the door 201 of the control box 200 is opened, The power is turned on in the box 200, and the inside of the box 200 is illuminated, and the power is turned on also in the monitor means 202, and predetermined information is displayed on the image display unit of the monitor means 202. ing.
Incidentally, the reset means 208 in the present invention may be able to recover normally by performing the reset processing operation when the gate part 30 in the present invention has stopped its opening / closing operation. Because there are many, it is an operation switch for trying first when a worker discovers a fault of the gate section 30 concerned.

Further, the manual gate body opening and closing means 210 in the present invention is for the operator to manually execute the opening operation and the closing operation of the gate unit 30 and the operation of stopping the operation. The switch switch means of
On the other hand, the wireless signal reception means 205 does not operate the control box, for example, in the vicinity of the site where the gate main body 3 is provided, using an appropriate remote controller or the like. It is for receiving a control signal from the remote controller so that the manual gate body opening / closing means 210 can be remotely operated to open or close the gate unit 30 or stop operation of those operations.
Of course, it goes without saying that the wireless signal receiving unit 205 is configured to be able to receive the same type of control signal transmitted from the remote location control unit 300 described later.

In the present invention, the seasonal mode switching means 209 needs the box internal temperature adjustment switch means 211 to adjust the temperature in the box according to the season. For example, in winter, under cold temperatures, Since there is a possibility that the computer may break down, it is necessary to set and maintain the temperature in the box high, so switching between the control mode for winter and the other control mode manually or remotely Switch means that can
In the present invention, the box temperature adjustment switch means 211 is turned on based on the selection of the season mode switching means 209 between the winter mode and the other season modes, and then the box temperature inside is changed. The adjusting means 212 is operated to set the in-box temperature adapted to the season mode.
Although these operations are performed manually, it is needless to say that software can be used to perform control operations in software.

Furthermore, as described above, the timer means 103 may stop the gate unit 30 at any timing after passing through the second sensor unit 14 while the gate unit 30 is performing the lowering operation. It is to set the time for making a decision.
Basically, the operator manually operates the timer means 103 to set a desired time interval, and it is naturally necessary to appropriately change the time interval according to the season. .
That is, in winter season when there is a concern about the occurrence of obstacles such as snow, the time interval is set short, while in summer there is no such concern, so it may be set longer. is necessary.

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

On the other hand, the first storage unit 214 connected to the data calculation control unit (CPU) 213 is a control program for driving the whole opening / closing control system of the elevation gate according to the present invention, for example, the gate unit A program for executing the opening / closing processing operation of 30 and reference operation data regarding the operation of the gate unit 30 are stored, and the difference between the operation state and the reference operation regarding the gate unit 30 described later is identified, An operation processing program or the like for determining whether the operation operation of the unit 30 is normal or not is built in, while the second storage unit 215 relates to the operation status of the gate unit 30. Are sequentially recorded and stored.

Furthermore, the monitor means 202 used in the present invention is constituted by an 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, when the open / close door 201 is opened, the monitor means 202 is configured to be activated, which is also a preferred embodiment.
Then, the monitoring unit 202 appropriately collects various data related to the current and past operation statuses of the gate unit 30 stored in the second storage unit into a desired format, as appropriate, or It is configured to display in response to a staff member's instruction.

If a specific example of the opening / closing operation of the gate unit 30 and the operation position of the inspection / repair etc. in the opening / closing control system 100 of the elevation gate according to the present invention will first be described, For example, when there is a request from the road management company to open the gate unit 30 of the gate main unit 3, the worker in charge goes out to the existing position of the gate main unit 3. First, the remote control is operated to execute the opening operation of the gate unit 30.
At that time, when the gate unit 30 is opened without any problem, or when the closing operation of the gate unit 30 after that is performed without any problem, there is a functional problem in the switching control system 100 for the elevator gate. However, at that time, it is preferable that the worker in charge opens and checks the control unit (control box) 200 provided in the vicinity of the gate main body 3. .

At that time, the monitor means 202 is checked to check the operation status of the gate unit 30 in the past, and the opening / closing operation of the gate unit 30 has not come to a stop in the past. It is desirable to investigate whether there has been no situation that would result in a failure reserve force.
Of course, as a result of the actual operation, when the gate unit 30 does not operate at all, or when a situation occurs in which the operation is temporarily stopped after being started, the same applies. The monitor means 202 is checked to check what causes the gate unit 30 to be inoperative and to check the operation status of the gate unit 30 in the past as well. Measures such as telephone or fax or mail to immediately notify the responsible department of the repair work of the cause of the failure and the policy of the failure repair as soon as the cause of the failure is identified. To arrange through.

Such a series of operations can be similarly performed in the remote place control unit 300 provided at a remote place different from the place where the gate main body 3 is disposed.
That is, the remote place control unit 300 in the present invention is joined to the control unit 200 provided at the site where the gate main body 3 is provided via appropriate means such as wire or wireless. The communication between the two is well secured.

Here, the control means provided in the remote place control unit 300 is, for example, as shown in FIG. 7, a wireless signal reception / transmission means 301, a monitor means 302, a reset means 303, a season mode switching means 309, Manual gate main unit 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 of the gate main body 3, warning of the gate main body Display means 308 and the like are provided.
If the configuration of the control means provided in the remote location control unit 300 is described in more detail, the operation of the open / close control system of the elevation gate disposed at the remote location remote from the installation site of the elevation gate In the remote location control unit that executes the above operation, the current and past operations of the elevation gate are transmitted from the opening / closing control portion of the elevation gate disposed adjacent to the installation site of the elevation gate. Reception means for receiving information on the situation, third storage means for storing information on the current and / or past operation situation of the particular elevation gate for each particular elevation gate, the third storage Operating condition information display means for displaying, from the information stored in the means, information on the current and / or past operating conditions of the specific lifting gate for each specific lifting gate Temperature controller control means for adjusting at least the temperature in the control unit, timer control means, reset means, vertical movement drive switch means for the elevation gate, disposed in the control section disposed at the installation site of the respective elevation gate The operation information of each control switch unit capable of remotely controlling the season switching means, the temperature control changeover switch means in the control unit, etc. individually, and the control switch unit is arranged at the installation site of the individual lifting gate It is a preferable specific example that the control switch unit operation information transmitting unit to be transmitted to the control unit is provided.

As a monitoring operation of the worker in the remote location control unit 300, for example, first, the worker operates the installation site selection means 307 of the gate main body 3 and the predetermined gate main body 3 By calling a predetermined area which has been arranged, the past and current status of the operation status of the opening / closing operation of the gate unit 30 of the gate main body 3 at the predetermined place through the screen of the monitor means 202 You can check it.

Further, the environmental condition around the predetermined gate main body 3 can be confirmed while looking at the image transmitted from the monitoring camera 215.
The operation concerned is not limited to the case where the worker himself checks the operation status of the gate main body 3 in the desired area, but also an ambulance for urgently transporting a traffic accident victim from a highway repair company or a fire department. Even when there is an emergency request to open the gate unit 30 of the gate main unit 3 in a predetermined area from the above, the manual gate main unit opening / closing means 304 is It becomes possible to open the gate part 30 of the desired said gate main-body part 3 from remote control by operating.
Also as described above, the main object of the present invention is to keep the gate unit 30 of the gate main body 3 in perfect movable state at all times, and to respond immediately and accurately to the urgent open request. It can be realized only by practicing the maintenance and control operations so that the opening and closing operations can be realized.

In addition, in response to seasonal fluctuations, mode change by season, adjustment of the timer setting time in the timer means 103, temperature control operation in the control box 200 at the relevant site, etc. 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, from the data of the current and past operation status of the gate unit 30 in the gate main unit 3 in the field, whether the operation regarding the individual gate unit 30 is normal, Warning information indicating that an inoperable condition is about to occur or incompetence will be determined through an appropriate arithmetic program used for the arithmetic processing means, and the result is obtained from the remote location control unit 300. 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 3 is disposed. Even in this case, it is possible to confirm the problem.

Next, in the opening and closing control system 100 of the elevation gate according to the present invention, the opening and closing operation of the gate unit 30 in the gate main body 3, which is the largest and most important, is absolutely defective. The basic technical configuration of the operation method and operation program for the maintenance operation for preventing the opening / closing operation from being inactivated will be described in detail.
That is, the basic technical configuration in the operation method and operation program for the maintenance management 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 Every time the opening / closing operation of the gate unit 30 is performed, the characteristic parameter of the operation element is measured, the parameter data, the operation occurrence date information of the gate unit 30, and the operation occurrence time At the same time when information is stored in an appropriate memory means, the stored parameter data is compared with preset standard reference value data to calculate, for example, the difference or ratio between the two. If it is processed and the result is 0 or within the allowable error range set in advance, it is judged that the opening / closing operation of the gate unit 30 is in the normal state, while the difference value or the difference value If the ratio, etc. exceeds the preset allowable error range, the opening / closing operation of the gate unit 30 is in a state where a failure state may occur due to any cause or may easily cause the failure state. It is judged that.

At the same time, by grasping the situation such as the occurrence frequency of occurrence of failure state in the operation, the number of occurrence, or the number of occurrence continuously, it is predicted in advance that the opening / closing operation of the gate unit 30 becomes inoperative. In advance, it is possible to create in advance a repair / repair schedule on which part of the gate main body 3 should be repaired / repaired at what time, and for maintenance workers It is possible to notify the information in advance.
Of course, in the present invention, even though the opening and closing operation of the gate unit 30 is instructed in the gate main body 3, the gate unit 30 does not execute the opening and closing operation. It is needless to say that it is determined that a fault condition exists.
Further, in the present invention, all the information and data related to the operation status regarding the opening and closing operation of the gate unit 30 described above are stored and accumulated in the second storage unit 214.

Furthermore, in the present invention, when the opening / closing operation of the gate unit 30 is inoperative from the beginning, the record of the opening / closing operation of the gate unit 30 in the past is similarly monitored by the monitoring means 202 or 302. By displaying on top and analyzing what kind of failure state has occurred in the past regarding the opening and closing operation of the gate unit 30, how to repair and repair which part of the gate main body 3 is concerned It is possible to accurately notify the maintenance worker of information as to how to do it, and to carry out a prompt, accurate, and appropriate repair operation.

The measured data values of the operating parameters representing the past and current operating states of the gate unit 30, and the determination results as to whether the operation is normal or not, or defective are displayed in time series, whereby the cause of the inactivity is It is possible to quickly and accurately grasp where it exists, and based on the information, it is possible to carry out repair work quickly, accurately and reliably, or the gate unit 30 It is possible to find out early the tendency and habits such as the time and time to generate good operation, and to predict when the relevant gate unit 30 will be in a non-operational state. It is possible to execute repair operation and adjustment operation to prevent occurrence quickly and accurately.

In the present invention, since the repair process and the pre-adjustment process can be constantly and accurately performed based on the operating condition regarding the opening and closing operation of the gate unit 30, the gate main unit 3 can be used. It is possible to always maintain and manage the opening / closing driving operation of the gate unit 30 in a normal state.

It is also one of the preferred embodiments to analyze the cause and display the result or the image information of the monitoring camera or the like on the monitor unit provided in the control device.

On the other hand, as still another specific example of the opening / closing control system 100 of the elevation gate according to the present invention, the person in charge of the operation of the opening / closing control system of the elevation gate is the cause of abnormality displayed in the monitor of the control means. After confirmation, first, the reset switch provided in the control means is operated directly or by remote control, and when the abnormal state can not be recovered, a personal repair operation is performed. It goes without saying that it may be configured.

Hereinafter, as an operation parameter related to the opening and closing operation of the gate unit 30 in the opening and closing control system 100 for the elevation gate according to the present invention, the time for the gate unit 30 to pass between the sensor units is adopted. Is measured at each operation execution time, stored in an appropriate storage means, the measured parameter data and the reference value parameter are compared, and if the comparison result is within a predetermined allowable value, normal And if it is other than the allowable value, it is determined that it is an abnormal condition, and the result shows that the opening / closing operation condition of the relevant gate unit 30 in the relevant gate body 3 is normal and / or An example of a concrete procedure for finding out the abnormal situation and using it for the practical treatment operation of appropriate repair and maintenance if necessary will be explained.

In addition, regarding the opening and closing operation of the gate unit 30 in the opening and closing control system 100 of the raising and lowering gate according to the present invention, the case where the gate unit 30 does not operate from the beginning or the gate unit 30 was initially driven If the operation is stopped during the one cycle counting, it is determined that an abnormal situation has occurred, and the repair / repair operation is immediately executed.
In the embodiment of the present invention, the first sensor means 13 described above is referred to as "upper stop sensor means 13" and the second sensor means 14 described above is referred to as "lower stop sensor means 14". The third sensor means 12 described above is referred to as "upper deceleration sensor means 12", and the fourth sensor means 15 described above is referred to as "lower deceleration sensor means 15".

And in this example, between the upper speed reduction sensor means 12 and the lower speed reduction sensor means 15, the gate portion 30 slides vertically at a first speed which is 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 unit 30 is at the high speed level. It shall slide up and down at the said 2nd speed which is slower than 1 speed.
It goes without saying that for the measurement of the passage time of the gate section 30 between the respective sensor means in this specific example, the passage time between any sensor means may be adopted, but in this specific example 1) The passing time between the lower stop sensor means 14 and the upper deceleration sensor means 12 (lower stop and upper deceleration), (2) between the lower stop sensor means 14 and the upper stop sensor means 13 (lower stop and upper stop) And (3) between the lower deceleration sensor means 15 and the upper deceleration sensor means 12 (lower deceleration and upper deceleration), and (4) between the lower deceleration sensor means 15 and the upper stop sensor means 13. Four types of passing 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, one cycle of returning to the original lower end stop position is performed. The driving process is counted as one count.
In addition, when the gate unit 30 in the gate main unit 3 is driven and operated, recording the year, date, drive start time, drive end time, and weather conditions of the area as necessary, each time At the same time, the distinction between whether the drive command has been made manually or by the remote control means including the remote control means is also recorded.

Here, an example of a specific procedure in the case of implementing the opening / closing control system 100 of the elevation gate according to the present invention will be described below with reference to the drawings.
First, when the system is started up, for example, when the door 201 of the control box 200 is opened, the system is powered on, and the monitor means 202 provided on the inner surface of the door displays a display as shown in FIG. Is displayed on the screen, and subsequently the gate in the basic gate main body 3 currently set in the control software in the opening / closing control system 100 for the elevator gate as shown in FIG. The drive conditions of unit 30 are displayed.
For example, it is desirable that the drive mode, the timer setting time, the first speed, the second speed, and the like be displayed.

According to the present invention, the system for controlling the opening and closing of the elevating gate 100 operates, each data described above is recorded during the operation, and at the same time, the 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 in the second storage unit 214 and stored.
This table can be optionally displayed on the monitor means 202 as needed by the maintenance management operator of the open / close control system 100 of the elevator gate, as described later.
That is, FIG. 10 shows an example of data to be stored at least when the opening / closing operation of the gate unit 30 is performed at one activation in the specific example according to the present invention. It is a thing.
In FIG. 10, reference value data to be compared with each actual measurement data is, for example, one stored in advance in the first storage unit 215 as described above.
In FIG. 10, for example, the location of the gate main unit 3 and its identification number, the recorded date and time, the time T1 when the gate unit 30 starts operating, and the gate unit 30 ends operation Time T2, distinction between manual operation and remote control including remote control, passing time X1 of (lower stop / up deceleration), passing time X2 of (down stop / up stop), (down deceleration / up deceleration) A comparison value (difference value Xn-X0) ΔX with the passage time X3 and the passage time X4 of (downward deceleration / upstop) and the reference value parameter X0, the determination result and the like are shown.

In this specific example, the passing time X1 of (lower stop / upper deceleration), the passing time X2 of (lower stop / upper stop), the passing time X3 of (lower deceleration / upper deceleration), and (lower deceleration / upper Each data regarding the passing time X4 of the stop), the comparison value (difference value Xn-X0) ΔX with the reference value parameter X0, and the judgment result etc. It is a further preferable embodiment to divide the data into two, measure and display the result.
Further, FIG. 11A is a diagram recording the situation in the case where the gate unit 30 does not operate from the beginning despite the start instruction in the system 100 in the present specific example, and more specifically, FIG. Specifically, when the gate unit 30 is inoperative, the reset switch 208 is first operated to try to drive the gate unit 30, and if it succeeds, the drive operation of the gate unit 30 is continued as it is. Measure the transit time data of each site and record the date and time of recovery.
In this case, the motion evaluation of each part is displayed as "non-normal".

On the other hand, when the drive of the gate unit 30 is not started even if the reset switch 208 is operated, the manual operation switch 210 is then operated, and when the drive is started by it, the gate is directly changed. The drive operation of the unit 30 is continued, and the transit time data of each part described above is measured, and the recovered date and time are recorded.
The motion evaluation of each part in this case is also displayed as "non-normal".
On the other hand, when the drive of the gate unit 30 is not started even if the manual switch 210 is operated, the display of “abnormal” is recorded, and at the same time, the management / maintenance worker is notified of the concerned of the gate main unit 3. At the same time as notifying that the gate unit 30 is in failure, an instruction to repair the gate unit 30 immediately is issued.
In this case, in FIG. 11 (B), the passing time X1 of the above (lower stop and upper deceleration) in FIG. 10, the passing time X2 of (lower stop and upper stop), (lower deceleration and upper deceleration In both of the passage time X3 of (3) and the passage time X4 of (downward deceleration and upward stop), the display is impossible of measurement, and the display of "abnormality" is described in the judgment 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 it succeeds, the drive operation of the gate unit 30 is continued as it is, If the drive of the gate unit 30 is not started even if the reset switch 208 is operated, the manual operation switch 210 is operated, and if the drive is started, the drive operation of the gate unit 30 is directly performed. On the other hand, if the drive of the gate unit 30 is not started even if the manual switch 210 is operated, the display of "abnormality" is recorded, and at the same time, to the management / maintenance worker, the gate main unit At the same time as notifying that the relevant gate unit 30 of 3 is out of order, a command to immediately repair the relevant gate unit 30 is issued.

On the other hand, FIG. 12 shows that the gate unit 30 is normally driven immediately after the start instruction in the system 100 is issued in this specific example, but at any time in any part. It records the situation in the case where the gate unit 30 has stopped its operation, for example, the passing time X6 corresponding to the passing time X1 described above (lower stop and upper deceleration) in FIG. The data can be measured at X7 corresponding to the passing time (lower stop, upper stop), and if it is within the allowable range in comparison with the reference value, the evaluation data of both will be displayed as "normal" However, the passing time of (lower decelerating and upper decelerating) and the passing time of (lower decelerating and upper stopping) are displayed as immeasurable because the gate unit 30 has stopped moving, and the judgment result column is “ The indication of "abnormal" will be described.

In such a specific example, it can be inferred that the gate unit 30 has stopped its operation in the (upper deceleration / upper stop) area.
However, since it may be considered that the gate 30 does not reach the completely open state or does not reach the completely closed state as it is, the manager / worker should be aware of the manual switch. It is a desirable specific example that it is configured to forcibly move the gate unit 30 to a predetermined position by operating 210.
Even in this case, when the gate unit 30 that has been inoperable is recovered by the manual switch, it is desirable to record the date and time of recovery and the recovery time.
In the present invention, various data as described above from the past to the present are stored in the second storage means 214.

Next, an outline of a program for executing management / maintenance of the opening / closing control system 100 of the elevation gate in 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 monitor 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 "abnormal" are listed and displayed in chronological order on the monitor unit 202, as shown in FIG. It will be done.
It is desirable that the data be classified and displayed on the basis of the identification data of the gate main body 3, and that the person in charge of the management and maintenance can specify the particular gate main body by inputting the identification data. It is also possible to display management data of only part 3.
As an example of display data in FIG. 14, for example, location, operating layer time, total number of activation times, abnormal state occurrence date and time, operation mode, timer setting time, distinction between manual operation and remote operation, the abnormal state It includes occurrence sites, transit times, comparison data with reference values, evaluation data, and the like.

On the other hand, when an abnormal state occurs in which the gate unit 30 maintains the inoperative state without responding to the activation instruction, first, the reset switch 208 is operated to attempt recovery, and the driving is started. In the case where the operation of the gate unit 30 is continued as it is and the drive of the gate unit 30 is not started even if the reset switch 208 is operated, as the manual information, as an example of the display data thereof. As shown in FIG. 15, data such as location, driving layer time, total number of activation times, abnormal state occurrence date and time, operation mode, timer setting time, distinction between manual operation and remote operation, and recovery completion date and time are included. .

Furthermore, in the system 100 according to the present invention, when it is said that an abnormal state occurs, for example, five times from the past in the same gate unit 30, the gate main unit 3 It is desirable to display on the monitor means 202 an alarm that it is necessary to immediately execute the drastic repair and repair of the whole, and when it is said that such an abnormal state has occurred, for example, five times, the gate unit 30. It is determined that there is a defect in the area and there is a high possibility that it will eventually lead to any failure itself. For example, as shown in FIG. It is a preferred embodiment to display on the monitoring means 202 an alarm that needs to be performed.

Below, one specific example of the operation procedure in the case of actually carrying out the said system 100 based on this invention mentioned above is demonstrated along the flowchart shown in FIG.
That is, first, after the start, in step 1 (ST1), the operation activation switch 400 of the opening / closing system of the gate unit 30 is turned on by manual operation or remote control, shifts to step 2 (ST2), and the gate unit If NO, the process proceeds to step 20 (ST20) to determine whether the gate unit 30 has fallen into an inoperative state in the middle of the drive cycle, If NO, the process proceeds to step 100 (ST100), and it is determined whether or not the "non-normal" mark is given to the information as described later, and if NO, the process proceeds to step 21 (ST21) If yes, the process proceeds to step 21 '(ST21') described later.

As described above, when the process proceeds to step 21 (ST21), the parameter data which is the transit time data at each of the above-described portions is measured, and the process moves to step 22 (ST22). In step 23 (ST23), it is judged whether or not the comparison value is within the allowable range, and if it is within the allowable range, that is, if it is YES, At step 24 (ST24), predetermined evaluation data indicating that the comparison value is "normal" is determined.
Thereafter, in step 25 (ST25), the result is stored in the second storage means 214, and the process proceeds to step 26 (ST26), where it is determined whether the opening operation of the gate unit 30 is completed or not In the case of NO, the process returns to step 20 (ST20), and the above-described steps (ST) are repeated, but in the case of YES in step 26 (ST26), the process proceeds to step 27 (ST27) and the gate It is judged whether or not the closing operation of the unit 30 is completed, and in the case of YES, it is END, but in the case of NO, the gate closing operation is executed in step 28 (ST28) and step 2 (ST2) The above-described steps are repeated.

In step 23 (ST23), it is determined whether the evaluation data falls within the preset allowable range. If NO, the process proceeds to step 34 (ST34). The evaluation data is determined to be "non-normal", and the result and the date when the "non-normal" state occurs are stored in the second storage means 214 in step 35 (ST35). After that, the process proceeds to step 36 (ST36), and it is determined whether the number of "non-normal" determined in the operation history of the gate unit 30 is, for example, 5 or more. It proceeds to step 26 (ST26).
On the other hand, if YES in step 36 (ST36), the process proceeds to step 37 (ST37) to generate an alarm, and in step 38 (ST38), a recommendation for repair processing of the gate unit 30 is made. In step 39 (ST 39), it is determined whether or not the repair work has been completed. If NO, step 39 (ST 39) is repeated, YES If so, the opening / closing operation is END.

If YES at step 100 (ST100), the process proceeds to step 21 '(ST 21') to perform data measurement, and the measurement result is compared with the reference value at step 22 '(ST 22'). , Step 34 (ST34), and the subsequent steps are performed.
On the other hand, if YES in step 20 (ST20), that is, if the gate unit 30 becomes inoperative during 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 means 208, it is determined in step 30 (ST30) whether or not the means gate unit 30 has restarted driving, and if it is YES Proceed to step 31 (ST31) to measure data on drive parameters, and in step 32 (ST32), compare the measured drive parameter data to 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 already exists in the drive state, so step 33 ( In ST33), it is considered that the evaluation is "non-normal", and the result and the date when the "non-normal" state occurs is 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 of "non-normal" determined in the operation history of the gate unit 30 is, for example, 5 or more. It will advance to 26 (ST26).

On the other hand, if YES in step 36 (ST36), the process proceeds to step 37 (ST37) to generate an alarm, and in step 38 (ST38), a recommendation for repair processing of the gate unit 30 is made. In step 39 (ST 39), it is determined whether or not the repair work has been completed. If NO, step 39 (ST 39) is repeated, YES If so, the opening / closing operation is END.
If NO at step 30 (ST30), the process proceeds to step 40 (ST40) to operate the manual switch means 210 to try to start the operation of the gate unit 30, and step 41 (ST41). In step 41 (ST41), the process returns to step 31 (ST31), and the subsequent steps are continued. If the answer is NO, the process proceeds to step 42 (ST42), and the gate unit 30 displays a display of "abnormality" indicating that the malfunction has occurred on the monitor means 202, and at the same time the date and time when the abnormal condition occurs. Are stored in the second storage means 214, and in step 43 (ST43), the management / maintenance worker is instructed to repair the gate unit 30.

Thereafter, in step 44 (ST44), it is determined whether the repair is completed and restored or not. If NO, the process returns to step 43 (ST43), and if YES, step 45 (ST45) Then, the second storage means 214 is made to store the information on completion / restoration of repair and the date and time of recovery, and the process returns to step 2 (ST2).
On the other hand, in step 2 (ST2), it is determined whether or not the operation of the gate unit 30 is inoperative. If it is inoperative, that is, if it is YES, the process proceeds to step 3 (ST3) to reset. In step 4 (ST4), it is determined whether or not the drive of the means gate unit 30 has started driving. If YES, the process proceeds to step 5 (ST5). After affixing the "not normal" mark (mark) to the information and simultaneously storing the state and the date of occurrence of the state in the second storage means 214, the process proceeds to step 20 (ST20). .

On the other hand, if NO in step 4 (ST4), the process proceeds to step 6 (ST6) and operates the manual switch means 210 to try to start the operation of the gate unit 30 and proceeds to step 7 (ST7). It is determined whether or not the opening / closing operation of the gate unit 30 has been started, and if YES, the process returns to step 5 (ST5) and the subsequent steps are continued, but in step 7 (ST7). If NO, the process proceeds to step 42 (ST42), and the gate unit 30 displays a display of "abnormality" indicating that the malfunction has occurred on the monitor means 202, and at the same time, the date and time when the abnormal condition occurred is displayed. After storing in the second storage means 214, in step 43 (ST43), the management / maintenance worker is instructed to repair the gate unit 30.
Thereafter, in step 44 (ST44), it is determined whether the repair is completed and restored or not. If NO, the process returns to step 43 (ST43), and if YES, step 45 (ST45) Then, the second storage means 214 is made to store the information on completion / restoration of repair and the date and time of recovery, and the process returns to step 2 (ST2).

Furthermore, as another specific example of the opening / closing control system 100 of the elevation gate in the present invention, for example, the cause of the abnormality is analyzed, and the result is displayed on the monitor means 202 or 302. It is also preferable to be configured to display the image information etc. of the monitoring camera on the control unit 200 or the monitor unit 302 provided in the remote control unit 300. It is.
Further, as a further different example in the present invention, for example, when the operation of the elevator gate, that is, the gate unit 30 in the opening / closing control system of the elevator gate is stopped or the abnormal state thereof can be visually confirmed. First, the person in charge of the opening / closing control worker of the gate unit 30 first displays the abnormal point and / or abnormality displayed on the monitoring unit 203 of the elevating gate opening / closing operation status information display unit provided in the control unit 200. After confirming the cause, when the reset switch 208 provided in the control means 200 or in the remote place control means 300 is operated directly or by remote control, and the abnormal state can be recovered, Although the control work is ended and the normal control operation state is restored, if the abnormal state can not be recovered, the control means Is configured to operate the manual type open / close operation switch 210 provided in to determine whether or not the abnormal state has been recovered, and to execute the human repair work if the recovery is still impossible. It is also a desirable embodiment to be done.
