BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a safety information providing system for a crane using a Bluetooth,

The present invention relates to a crane, and more particularly, to a crane using a Bluetooth which can improve the safety of a worker by enabling a worker to easily confirm information about the size, direction, or movement of a crane supported by the crane And a safety information providing system.

Generally, a high-altitude work vehicle equipped with a crane is a device that allows an operator to work at a certain altitude for the purpose of installation, demolition, or maintenance of a high-voltage line installed on a telephone pole.

A high-altitude working vehicle having such a crane is disposed on an upper portion of a vehicle body for traveling, and is provided with a crane composed of a plurality of expandable and contractible booms, so as to be rotatable in the vehicle body. In addition, a bucket is coupled to the distal end of the crane so that a worker can ride on the inside of the crane or can house the equipment.

Such a crane is a device for working in a high place, and the boom, the bucket and the connection part of the crane are made of an insulating material.

The crane includes a bucket 4, a stationary boom 1 that engages with the crane main body, a terminal boom 3 that is connected to the bucket at one end, and a stationary boom 3 that performs a stretching operation between the stationary boom 1 and the end boom 3 And is constituted by one or more stretching booms 2 in general.

Such a crane may be provided in a movable or fixed manner, and when it is movable, it is coupled to the vehicle body so as to be movable in a predetermined work place.

A high-performance work vehicle having the above-mentioned crane precedes the work of aligning the equipment and supporting it against the ground before performing the high-altitude work. For example, in the case of a mobile work vehicle, an outrigger is generally provided on the left and right sides to prevent rollover accidents. Such an outrigger is extended to the left and right sides to prevent overturning due to misalignment.

On the other hand, devices equipped with such a crane are determined by the length of the crane and the limit moment due to the load supported by the end, depending on the weight of the vehicle, the arrangement of the crane, the structure of the outrigger, and the like.

[0004] However, there is a need for an operator working in a bucket of a high altitude to extend a boom from a main body of the vehicle to a remote place and to support a high load in some cases depending on a work situation. It is impossible to make calculations, so that it performs sensuous work, which often leads to rollover accidents.

To prevent this, an AML device is recently installed. AML (Automatic Moment Limiter) is a device to prevent overloading of such special vehicles. It is a device that weighs loads and generates alarms.

However, due to the fact that the crane is operated from a distance from the vehicle, it is very difficult to transmit such alarm to the worker. Therefore, the risk of safety accidents is higher than that of other special vehicles. do.

Hereinafter, a safety information providing system for a crane using a Bluetooth according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention provides a safety information providing system for a crane, wherein the crane can be a predetermined boom assembly composed of an expandable boom arrangement, and the safety information providing system of a crane using the Bluetooth of the present invention, It should be noted that a crane such as a crane or a mobile crane can be installed in various devices or vehicles as long as the operator can directly or automatically manipulate the crane. Also,

2 is a side view of a crane to which a safety information providing system for a crane using Bluetooth according to the present invention is applied.

The present invention basically comprises a crane having a boom (100) arranged to be able to extend and retract in the longitudinal direction, an operating part (120) disposed in a vehicle to which the crane is coupled and operated by an operator, A microcomputer for collecting and outputting operating state information of the crane, a Bluetooth module connected to the microcomputer, and a mobile device 200 interlocked with the microcomputer through the Bluetooth module and displaying information of the crane on the screen .

The crane is constituted so that a plurality of booms (100) are formed as an assembly and can be pulled in and drawn out from each other to support a predetermined load at one end side. The number and shape of the boom 100 to be drawn in and out are not necessarily limited to the illustrated examples of the present invention.

The crane may be provided at a predetermined mounting portion of the vehicle. The crane comprising the boom assembly is arranged to be capable of pivoting up and down with one end supporting the load and being supported by the vehicle at the other end. Further, the crane may be rotatable in the left-right direction with respect to the vehicle.

The power of the above-mentioned crane, that is, the pulling-in and pulling-out operation of the boom 100, the up-and-down turning and the left-right rotation can be taken out from the vehicle. And is preferably operable through hydraulic pressure.

2, the crane can be provided with an operation unit 120 on which an operator can operate the crane directly. The operator can operate the crane by means of the extension and retraction of the crane, the up- Can be directly operated.

However, the arrangement of the operation unit 120 is not limited to the other side of the crane, that is, the side where the rotation is performed, and may be disposed on the end side of the boom 100. In this case, a predetermined bucket may be provided on the distal end side of the boom 100, and the control unit 120 may be formed in such a manner that a predetermined control line is extended to the bucket so that the operator can ride the boom . It is needless to say that the arrangement of the operating portion 120 is not directly coupled to the crane but may be disposed on the driver's seat side or the rear or rear side of the vehicle. Further, the crane is not necessarily limited to the state of being coupled to the vehicle, but may be fixed directly to the ground, or may be coupled to a railway track device.

In the end portion of the boom 100, predetermined operating devices to which a load for work can be applied may be added. For example, as shown in the drawing, a winch 110 is coupled and a predetermined wire is wound The object can be moved up and down. However, the operating device may be variously selected.

Here, the boom 100 may be disposed at a predetermined distance from the place where the vehicle is disposed. The boom 100 may be disposed such that the distal end thereof is spaced apart from the vehicle by a predetermined distance. As the distal end moves away from the vehicle with respect to the plane, The moment at the support portion of the crane, that is, the joint portion between the vehicle and the crane, becomes larger. As a result, there is a problem that the vehicle itself may be overturned in the event of breakage of the members or serious cases.

Accordingly, the present invention provides a concept that a mobile device of a crane can be interlocked with a mobile device using Bluetooth.

According to the concept of the present invention, the crane includes a microcomputer (330 in FIG. 3) for collecting information of a crane or outputting a control signal to a crane, a Bluetooth module (320 in FIG. 3) connected to the microcomputer, And a mobile device 200 interlocked with the microcomputer and displaying information of a crane on a screen.

The information of the crane may be received by the mobile receiving apparatus 200 through the microcomputer and the Bluetooth module, or the crane may be operated through the mobile receiving apparatus 200, which will be described below in more detail.

3 is a conceptual diagram illustrating a system for operating a safety information providing system of a crane using Bluetooth according to the concept of the present invention.

The mobile device 200 and the microcomputer 330 can be interlocked with each other through the Bluetooth module 320.

The sensing signal processing unit 332 of the microcomputer 330 receives sensing signals from predetermined sensor units 311, 312, and 313 disposed in the crane, and can process each detected value as a variable.

In the operation unit 334, the values processed by the sensing signal processing unit 332 may be calculated through a predetermined operation to produce data such as a working radius and a limit load of the crane, as described later.

The danger determination unit 333 compares the measured load values when the computation unit 334 provides a limit load with a risk of rollover, for example, with respect to the angle of the crane and the elongated length, It can be judged that there is a risk.

The alarm generator 335 may generate an alarm through the visual device, the auditory device, or the tactile device in the mobile device 200 when the risk determiner 333 determines that the risk of rollover is high.

Accordingly, the microcomputer 330 collects vehicle information and analyzes information related to loading or unloading of the crane through a predetermined signal processing and determination process, and outputs the limit operation of the crane to the mobile device 200 It will be done.

The communication control unit 331 allows the microcomputer 330 to perform bidirectional communication with the Bluetooth module 320 and the crane. The connection with the crane can be performed in various ways, desirable.

The sensor units 311, 312 and 313 include a load sensor 311 for detecting a load supported on the distal end side of the boom 100 and an elastic sensor 311 for sensing the length of the boom 100, And a turning sensor 313 for detecting the up-and-down rotation or the left-and-right turning of the boom 100. The data that can provide the operation status of the crane, . In addition, the sensor unit is not necessarily limited to the above-described sensors. The sensor unit may further include a sensor for detecting a total load at a joint portion between the crane and the vehicle, a sensor for receiving the current angle of the vehicle, The sensor unit may be understood to include a GPS device or a velocity sensor.

Accordingly, in the concept of the present invention, predetermined states of the vehicle detected by the sensor units 311, 312, and 313 are input to the microcomputer 330 and information processing is performed, and the microcomputer 330 transmits the Bluetooth module 320 So that information related to the crane can be visually or audibly confirmed by the mobile device 200 to the operator.

The Bluetooth module 320 can be interlocked with the mobile device 200 of the operator in accordance with a predetermined Bluetooth standard and the operator can directly or indirectly operate the operation unit 120 And can connect or disconnect the mobile device 200 wirelessly via the transmitting / receiving unit of the Bluetooth module 320 to be disposed.

Accordingly, in this case, since the mobile device 200 individually provided for each worker can be connected by selection, a separate display device or complicated wiring can be omitted, but it is easy to carry and has an advantage of being able to perform an operation familiar to an individual operator shall.

The operator can download a predetermined application from the mobile device 200 and operate a predetermined information providing interface. The interface will be described later with reference to FIG.

The microcomputer 330 can be connected to a predetermined control module 121 that can operate the crane through the mobile device 200. The operator can operate the mobile device 200 to transmit the control signal to the Bluetooth module The microcomputer 330 receives a signal from the microcomputer 330 through the microcomputer 320 and transmits the signal to the control module 121 to operate the crane.

The control module 121 may be provided on the operation unit 120 or may be separate from the operation unit 120 or may be integrated with the microcomputer 330.

FIG. 4 is a view illustrating a first embodiment in which AML information is displayed in a mobile device in which a safety information providing system for a crane using Bluetooth according to the concept of the present invention as described above is implemented.

Although the mobile device 200 is shown as an example of a smart phone in the exemplary embodiment of the present invention, the mobile device 200 may be optional and may include a predetermined wireless communication means such as a tablet or a notebook And a device to which the display device is coupled.

The mobile device 200 may include an image display unit 210 and an AML information display unit 231 as an example to be displayed. The image display unit 210 can visually and intuitively display the current work state through the shape of a predetermined crane. Information such as the angle of the crane, the rotational direction, or the degree of the load can be visually displayed have.

The AML information display unit 231 can display accurate information related to the current overload (rollover) through a predetermined numerical value. The AML information display unit 231 includes an angle display unit 232, a load display unit 262, A working radius display unit 234, and an error message unit 235. [

The angle display unit 232 converts the detection signal of the boom 100 inputted through the rotation sensor 313 into a predetermined signal by the microcomputer 330 and transmits the detection signal to the mobile device 200 ) Indicating the angle at which the current crane is turned up and down with respect to the ground or the vehicle.

The load indicator 262 may represent a load supported by the current crane which may mean a load on the entire structure of the vehicle or a load on the crane and a load And may mean the load of the object supported on the end side of the boom 100. [

However, since the load of the boom 100 is a fixed value and the moment due to the crane can be determined by the length of the boom 100, it is preferable that the load is a load of the object directly supported at the end of the crane.

In addition, the working radius display section 234 can display the radius of the limit at which the work can be performed on the end side of the crane, or the radius at which the current work can be performed. It is needless to say that these two pieces of information may be displayed together .

Further, the error message section 235 functions to display a warning when a problem in operation at the time of operation occurs or when the limit of the structural work of the crane is reached. The error message unit 235 may be configured to receive the new route provided by the alert generator 335 via the Bluetooth module 320 and to visualize the new route when the risk determiner 333 determines that it is dangerous.

The error message unit 235 can be visually represented by the AML information display unit 231 as shown in the figure, and can transmit a predetermined alarm signal to an operator through sound or vibration.

As described above, when an alarm signal is transmitted to a worker through vibration or sound, an operator can provide an alarm signal through the equipment carried by the operator, compared to a case where the operator sensibly judges whether or not the worker operates the limiter It has the advantage of significantly reducing the risk of accidents.

Particularly, in the case of a crane, in many cases, an object having a large load is operated, and accordingly, an operator is required to concentrate. Therefore, an alarm signal is provided to the portable mobile device 200 through other sensory means such as sound or vibration The efficiency of detection of the danger can be dramatically improved.

As described above, when the mobile device 200 transmits an alarm signal to the operator through vibration or sound, the visual indication may be omitted.

In the meantime, the concept of the present invention can provide a display and an input means for the mobile device 200 to selectively provide various information.

The movement information display unit 241 may include the speed display unit 242, the movement distance display unit 243, the fuel consumption display unit 244, and the movement time display unit 245, but is not limited thereto.

The movement information display unit 241 interlocks with a predetermined GPS module provided in a vehicle to which the crane is coupled to provide accurate position and movement related information to the microcomputer 330. This information is transmitted to the Bluetooth module 320 To the mobile device 200 via the Internet.

In addition, the movement information display unit 241 may be operated in conjunction with navigation (not shown) mounted on the vehicle.

The inclination display unit 236 may be linked to an angle sensor or a gyro sensor provided on the crane or the vehicle body to transmit the overall inclination to the operator. Here, the crane can have a predetermined slope with respect to the horizontal plane due to the shape of the ground on which the vehicle is placed or the moment that it is hanging, and such slope value can affect the elements of the marginal operation of the vehicle.

For example, when the entire crane is arranged so as to be inclined forward in the initial state, since the limit value of the moment that can be received ahead of the limit value of the moment that can be received backward is smaller, Basic information is provided so that it can accurately grasp whether or not the limit is reached.

The AML information display unit 231a may further include an accumulation display unit 237. The accumulation display unit 237 may display a load accumulated in a current crane or a vehicle.

The image display unit 210 may further include a task radius display unit 210 in the third embodiment in which the AML information display unit 231b of the mobile device 200 is displayed.

The work radius display unit 210 can display the radius of the vehicle, more specifically, the radius that can be worked by rotating left and right around the joint between the crane and the vehicle. Accordingly, Can be visually confirmed.

Here, the working radius of the crane can be expressed in various ways, but it is preferable to display the rotation angle of the boom 100 with respect to the actual vehicle in a call shape or a fan shape.

The manner of display in the mobile device 200 according to the embodiments of the present invention as described above is not necessarily limited to the example of the present invention, and the type of the equipment mounted on the crane, the type of the vehicle, Can be variously set according to the types and the types and locations of the sensors to be disposed and the information can be implemented by various sensory means in the mobile device 200 through the Bluetooth module 320, Can be secured.

The various information may be accumulated and stored in the microcomputer 330 and may be further provided with a function for confirming the content of the work in a posterior manner. In addition, in the above embodiments, an alarm about rollover or undesirable behavior of the vehicle It can be provided visually as well as auditory and tactile.

More specifically, when the end of the crane reaches the limit position or the value of the moment due to the load becomes close to a predetermined set value, the mobile device 200 can transmit an intuitive alarm to the operator through vibration or alarm, It should be noted that the transmission of alarms can be made significantly more efficient than in the prior art.

Meanwhile, the mobile device 200, which is a constitution of the safety information providing system of the crane using the Bluetooth of the present invention, is a kind of remote which can directly operate the operation of the crane, It can function as a controller.

9 is a view showing an embodiment of the operation mode in the mobile device of the safety information providing system of the crane using the Bluetooth of the present invention.

As described above, when the operator switches to the predetermined operation mode window through the function setting unit 260, the display as shown in FIG. 9 can be performed. Specifically, the rotation adjusting unit 264, the vertical adjusting unit 265, an extension / contraction adjustment unit 266, and a winch control unit 267.

The rotation control unit 264 controls the rotation of the boom 100 in the left and right direction and the vertical control unit 265 functions to adjust the vertical tilting angle of the boom 100. The rotation control unit 264 controls the expansion / The distal end side of the boom 100 can be moved to a desired position by adjusting the degree of pulling and pulling out between the booms 100. [

The adjustment may be performed by an operator's input, such as a predetermined button touch. As shown in the figure, the operation may be performed in two directions, forward and backward, for each function. However, no.

When the position of the boom 100 is adjusted, a predetermined work device positioned at the distal end side of the boom 100 can be adjusted through a touch, and as shown in FIG. 9, (267) may be further provided. However, it is needless to say that the winch control unit 267 can be changed to a button for operating another device.

The load display unit 261, the load display unit 262, and the warning display unit 263 may further include a function similar to the AML information display function in the entry state of the operation mode for operation.

The display of the information is provided to the mobile device 200 via the Bluetooth module 320 by collecting information from the sensor units 311, 312 and 313 received by the microcomputer 330.

The load display unit 261 may display a load simply as in the AML information display unit 231 described above, but it is preferable to express the load factor, which is predetermined processed information, as a percentage in order to provide substantial safety information. For example, if the limit load that can be supported by the crane is 100%, it is possible to intuitively indicate the proximity of the work to the limit value at a relative ratio to the limit load.

The load indicator 262 represents the present load.

As described above, it is possible to provide information related to the risk of the work to the worker through the provision of various information. In addition, it is possible to visually provide the risk through the warning display unit 263 in the work mode.

Such a risk can be made as a display of a predetermined level or color, for example, in a blue state in a state in which a margin of a supported load is large, in a state of being green in a state in which a load is increased to some extent, But the present invention is not limited thereto.
