Description

SAFETY MANAGEMENT SYSTEM WITH COUPLING CHECKING SENSOR OF SAFETY HOOKS FOR HIGH-PLACE WORKING

The present invention relates to a safety management system having a safety ring fastening confirmation sensor for high-altitude work, and more particularly, whether a worker at a high-altitude workplace has fastened the safety ring of the safety belt to the safety belt or wire for preventing a fall through the sensor. It relates to a safety management system equipped with a safety hook fastening confirmation sensor for high-altitude work that automatically detects in real time and warns when non-tightening, and at the same time, transmits whether non-tightening to a manager through wireless communication for control.

When working at a high position from the ground (usually referred to as work at height), such as construction sites for constructing structures such as buildings and bridges, pylon and telephone pole work, and assembly work of large shipbuilding structures, a lifeline is used to protect workers from the risk of falling. It is compulsory to wear a seat belt including a fall prevention safety rope (a.k.a.

A structure is installed to prevent the fall of the worker at the high-altitude workplace, and the fall prevention structure takes various forms such as a rope and a steel bar for safety Also called a fixture) is installed.

When working at height, all workers are obliged to hang the safety ring of the fall prevention safety rope on the fall prevention safety line of the fall prevention structure.

However, many workers are working without the safety hook on the safety line because of the inconvenience of operation, such as restrictions in movement and operation between jobs when working with the safety hook on the safety line. As of 2018, more than 50% of the deaths were caused by falls.

Managers manage whether or not workers at heights are wearing seat belts, but it is difficult to continuously identify and manage whether the safety rings are actually fastened. For convenience, many workers are working without fastening the safety hook to the fall prevention safety line.

After wearing the safety belt, the safety ring of the safety rope for fall prevention is fastened to the safety belt of the worker, such as the band on the left or right side of the front part of the safety belt worn by the worker, the safety swing band, and the safety rope connection ring on the back side. and move

When working at height, the safety hook must be fastened to the safety line for fall prevention, but the work is carried out with the safety ring fastened to the safety belt as above, or there are cases where work is performed without fastening to the safety line and on the floor. .

Invented from the above point of view, "Safety management device at a construction site using RFID" of Registered Patent No. 10-0966892 (hereinafter referred to as the preceding 1) and "Work using a seat belt unit for high-place work" of Registered Patent No. 10-1964727 Safety management system" (hereinafter referred to as preceding 2), and "safety equipment for work at height and safety management system using the same" of Utility Model Registration No. 20-0482611 (hereinafter referred to as preceding 3), and the like.

Here, before examining the preceding 1 to 3, it is necessary to check whether the following functions are provided, which will be compared and mentioned in [specific content for carrying out the invention] to be described later.

That is, ① whether there is a device that can induce the safety loop to be tightened, ② whether communication and ID functions are provided to inform the manager of the status of whether the safety loop is not fastened, ③ whether the relevant work area is Whether it is necessary to determine whether it is a necessary high-altitude work area, ④ whether the operator can arbitrarily operate the device that determines whether a safety ring is engaged, to stop or release the function, and ⑤ whether a system is in place for the manager to manage and take measures for the high-altitude work area Let's take a look at whether or not

Prior 1 ① When the safety ring is fastened to the safety line, the contact sensor (switch) operates due to the weight of the safety ring applied in the vertical (gravity) direction.

And, the preceding 1 is ② a communication and ID function to notify the manager of the non-tightening status of the safety ring, and separately from the device for determining whether the safety ring is fastened, a wired/wireless communication type RFID reader device is installed on the seat belt to manage communication and ID are doing

However, the preceding 1 lacks a device capable of determining whether it is a high-altitude work area requiring the ③ safety loop.

In addition, the preceding 1 does not have a function to prevent arbitrarily releasing the ④ operator's safety ring fastening determination device.

In addition, the preceding 1 does not have a system for the management and action of ⑤ the high-altitude work area of the manager.

On the other hand, in the preceding 2, ① when the safety ring is fastened to the safety line, the pressure sensor (physical, electrical) is activated due to the weight of the safety ring applied in the vertical (gravity) direction, so it is determined whether the safety ring is fastened.

And, in the preceding 2, a separate device (safety ring holder) of the wireless communication method is installed on the seat belt separately from the device for determining the fastening to the safety ring, and communication and ID management are performed, so it is very cumbersome and bulky. .

And, since the preceding 2 includes a module capable of measuring the position and altitude (3) in a separate communication device (safety ring holder), it has a problem of inconvenient portability due to its large volume and heavy weight.

In addition, the preceding 2 does not have a function for preventing the operator from arbitrarily releasing the safety ring fastening determination device ④.

In addition, in the preceding 2, a separate management system is established ⑤ and warning measures are taken through a device separate from the device called the warning generating unit installed on the safety belt of the worker in the work area, so the control algorithm is complicated, cumbersome, and malfunctions. There are many concerns about

On the other hand, in the preceding 3, ① if the safety line is installed at a higher position than the operator and there is a safety ring at a position higher than the operator through a device that can measure the position of the safety ring, it is judged that the safety ring is engaged, or the safety line and the safety ring After installing separate devices capable of transmitting and receiving signals, it is determined whether or not the safety ring is fastened through contact between the two devices.

And, in the preceding 3, ② information about a plurality of devices of at least 5 types is mutually communicated with the manager through a separate outgoing module, but the individual ID grant function is lacking.

And, the preceding 3 is accompanied by the inconvenience of having to use a module device capable of measuring a separate location and altitude (3) and the inconvenience of portability.

In addition, the preceding 3 does not have a function to prevent the operator from arbitrarily releasing the safety hook fastening determination device.

In addition, the preceding 3 establishes a management system of the ⑤ control center concept, and in order to directly notify the operator, a separate alarm generating unit is used to propagate a warning, so the control algorithm is complicated and cumbersome, and there are many concerns about malfunction.

Above all, preceding 1 and preceding 2 determine whether the contact sensor (switch) or pressure sensor (physical, electrical) that operates due to the weight of the safety ring applied in the vertical (gravity) direction works when the safety ring is fastened to the safety line. judge

However, this determination algorithm is the safety ring itself even when the safety ring is fastened to the safety belt of the operator, such as the band on the left or right side of the front part of the safety belt worn by the operator, the safety swing band, and the safety rope connection ring on the rear side. Due to the weight (about 500g), the same reaction (contact sensor or pressure sensor operation) as in preceding 1 and preceding 2 occurs, so even if you do not actually fasten the safety ring to the safety line, the sensor reaction causes the safety ring to be mistakenly fastened to the safety line. can do.

In addition, the preceding 3 judges whether the safety ring is fastened by the position of the safety ring because the safety line is at a higher position than the worker. does not exist.

In addition, the method of installing each touch sensing transceiver on the safety line and the safety ring in Prior 3 requires a lot of money and effort to apply due to the problem of having to install a separate device on the safety line, so it is applied to actual work at height. There are clear limitations to

In addition, FIG. 5 shows that in the safety management system having a safety ring fastening confirmation sensor for high-altitude work according to an embodiment of the present invention, the first unit 100 entered the high-altitude workshop 500 together with the worker, but the safety ring 101 ) is a conceptual diagram schematically showing an uncontracted state.

First, according to the present invention, as shown in FIG. 1 , it can be understood that the first unit 100 , the second unit 200 , and the third unit 300 have a communication structure.

The first unit 100 is provided on the left and right sides of the safety ring 101, which is detachably provided on the operator's safety belt and is detachably coupled to the fall prevention safety belt or wire 400 for high-place work, and the safety ring 101. It may include sensors 111 and 112 that detect in real time a seat belt or wire 400, or a contact or proximity with an object, structure, or person.

The first unit 100 determines whether the safety ring 101 is fastened to the seat belt or wire 400 when the worker enters the high-altitude workplace 500, and the sensors 111 and 112 determine whether the worker is alerted to, or It is provided to perform a role of transmitting information on whether the worker's current location information and the safety ring 101 are engaged by short-distance or long-distance communication.

The second unit 200 is provided in the high-altitude workshop 500 and is capable of communicating with the first unit 100 .

The second unit 200 receives from the sensors 111 and 112 whether or not the worker who entered the high-altitude workplace 500 fastens the safety ring 101 to the seat belt or wire 400, the worker and other workers around the worker. A warning informing the 600 is delivered to the first unit 100 of the worker and the first unit 100 of the other workers 600 .

The second unit 200 transmits information on whether the worker's current location information and the safety ring 101 are engaged by short-distance or long-distance communication.

The third unit 300 is capable of short-range or long-distance communication with the first unit 100 and the second unit 200 .

The third unit 300 transmits information on whether the worker's current location information or the safety ring 101 is fastened to the first unit 100 of the worker and the first unit 100 of the other workers 600 do.

The third unit 300 also performs a role of collecting and managing data on whether the safety ring 101 is fastened and the fastening confirmation of the corresponding worker and other workers 600 is performed.

It goes without saying that the present invention can be applied to the above-described embodiments, and can also be applied to the following various embodiments.

First of all, the majority of workers who work without hooking the safety ring 101 to the safety belt or wire 400 for fall prevention in a high-place workplace are the band on the left or right side of the front part of their seat belt, the safety swing band, and the safety rope connection ring on the back side. The safety ring 101 is connected to the back and the work is performed. In addition, some workers may work with the safety ring 101 on the floor of the workplace.

When the work is performed without fastening the safety ring 101 to the safety line, one side of the both sides of the safety ring 101 must come into contact with the worker or the floor of the high-altitude workplace, or close at a very close distance (within a few centimeters). .

As shown in FIG. 2, the sensors 111 and 112 are sensors capable of detecting a nearby object (proximity sensor, ultrasonic sensor, etc.) or a sensor capable of detecting a human body (infrared sensor, radar sensor, etc.) or a combination of two or more sensors. If both sides of the safety ring 101 can be detected using the ) can be determined in a state in which the seat belt or wire 400 is not fastened.

In addition, the safety ring 101, which can be determined in a state in which the safety ring 101 is fastened to the safety belt or wire 400, by whether the sensors 111 and 112 are in contact or proximity detection, is installed as a safety belt or wire 400 for fall prevention. ), due to the shape and weight of the safety ring 101 itself, the sensors 111 and 112 do not detect a contact or close object or human body as shown in FIG. ) can be considered to have been entered into.

On the other hand, the first unit 100, referring back to FIG. 1 in more detail, the first communication unit 120, the first location unit 130, the first notification unit 140, and the first power unit 150 and a first microcontroller unit 160 (hereinafter, a first MCU 160 ) and an on/off unit 170 .

The first communication unit 120 is electrically connected to the sensors 111 and 112, information of the sensors 111 and 112 through short-distance or long-distance communication, location information of the high-altitude workplace 500, and the third unit 300 ) is to transmit and receive system safety information provided by the first unit 100 and the second unit 200 and the third unit 300 of other workers 600 .

The first location unit 130 acquires information on the current location and altitude of the worker, and shares the information of the high-altitude workplace 500 obtained from the first communication unit 120 .

In the case of preceding 1 to 3, for example, when the operator moves to the high-altitude work section through the section where the work on the upper part of the bridge has been completed, from the moment he enters the bridge, he receives a warning according to the non-fastening of the safety ring, You may feel cluttered, uncomfortable, and uncomfortable.

On the other hand, the first location unit 130 according to the present invention analyzes the information on the work location and at the same time receives the work information at high altitude from the second unit 200 to be described later installed in the high place 500 through short-distance communication or at a long distance. It is possible to increase the accuracy of the determination of the high-altitude work area by simultaneously reflecting the work information input in advance to the third unit 300, which will be described later, through communication.

In particular, when the first unit 100 is only capable of short-distance communication, the second unit 200 installed in the high-altitude workplace 500 provides information on the high-altitude workplace 500 to the first unit 100 through short-distance communication. and receives the safety information processed from the third unit 300 in addition to the function of transferring the information of the first unit 100 to the manager through long-distance communication, and the safety ring 101 through its own warning sound or voice guidance ) to be fastened, and by transmitting information to the first unit 100, it is possible to induce the fastening of the safety ring 101 through a warning sound, a warning vibration, a warning LED, and the like.

The first notification unit 140 is electrically connected to the sensors 111 and 112 and the first communication unit 120 and can communicate with the third unit 300, and the safety ring 101 through sound, vibration, voice, or light. ) to imprint the non-tightening state to the worker, or to transmit safety instruction information through the third unit 300 .

The first power unit 150 includes a storage battery (not shown below), a charging/discharging circuit electrically connected to the storage battery (not shown below), and power to the storage battery to supply power necessary for operation of the first unit 100 . It may include a solar cell (hereinafter not shown) for supplying the.

The first MCU 160 controls the overall operation of the first unit 100 , and includes the sensors 111 and 112 , the first communication unit 120 , the first location unit 130 , and the first notification unit 140 . It analyzes the operation information of the first power unit 150 , instructs operation and stop operation, and at the same time assigns and manages an individual ID for each worker who owns the first unit 100 .

The on-off unit 170 is operated in connection with the first MCU 160, and the first unit 100 can be turned on and off only by a button operation or a password according to a previously input pattern. ) to prevent the operator from arbitrarily operating it and releasing the function.

In the preceding 1 to preceding 3, there is no function to prevent the operator from arbitrarily releasing the safety ring or stopping the function by turning off the power. It can be seen that there is no preparation for the inoperable state that can do this at all.

This problem is that the manager has to check whether the device is operated one by one, but this is to face a problem that is practically impossible when the work area including the high-altitude workshop 500 is wide.

On the other hand, the on-off unit 170 according to the present invention operates the first unit 100 for operation of the first unit 100. For example, when the power button is turned on, the device is operated with one button operation, but when it is OFF, a prior agreement When a special button operation (eg, power OFF during continuous operation of the 1st - 3rd - 2nd - 1st button operation) is recognized, the power of the first unit 100 is turned OFF so that the operator can arbitrarily release the device. By making it impossible, it is possible to induce the safety ring 101 to be always fastened when working at height.

In addition, a password may be assigned to the above-described on/off button or ON/OFF may be managed only by an administrator through another mechanical device in addition to the password operation exemplified above.

That is, the first unit 100 includes the safety ring 101 , the sensors 111 and 112 , the first communication unit 120 , the first location unit 130 , the first notification unit 140 , and the second unit 100 as described above. 1 Since the power unit 150, the first MCU 160, and the on-off unit 170 are provided in an integrated form, it is possible to attach and detach the safety belt 101 or the safety rope (not shown below) of the operator's safety belt. Because it is possible, it will be possible to use it by mounting it in various positions.

Existing technologies including Prior 1 to Prior 3 have problems in that a device for determining whether a safety ring is fastened and a device for communication are separately provided and managed, which increases the inconvenience and bulkiness of installation. In the case of a wireless connection, there is a problem that the operation and movement of the operator is disturbed, as well as the electrical connection is cut off during the work process.

In contrast, the first unit 100 according to the present invention, as described above, the safety ring 101, the sensors 111, 112, the first communication unit 120, the first location unit 130 and the first notification unit ( 140), the first power unit 150, the first MCU 160, and the on-off unit 170 are provided in an integrated form, so the operator's safety belt, the safety ring 101 or the safety ring connected to the safety belt Since it only needs to be installed and used in the connection part, it will be possible to block the fear of malfunction and increase the convenience of management.
