Description

Heavy object fall hazard warning system for preventing industrial accidents {Warning system for heavy object fall hazard to prevent industrial accidents}

The present invention provides a warning in advance to a dangerous area included in the moving radius of a heavy object during aerial movement of a heavy object such as crane work at a construction site, thereby preventing an industrial accident that can prevent a worker's accident due to a heavy object falling It relates to a hazard warning system.

In general, a construction site or industrial site is a labor-intensive industry in which numerous field workers are input and multiple tasks are performed simultaneously.

However, in the conventional construction site, as safety accidents frequently occur due to the dangers caused by various environments inherent in the site itself and due to the slight negligence of the workers, there is a fatal problem in that valuable human resources are lost.

Numerically, while the number of industrial accidents decreases every year, construction accidents increase every year, increasing the ratio of construction accidents to total accidents, accounting for about 28% of all industrial accidents.

In particular, at the construction site, field workers in various fields are deployed across multiple tools to perform their own work, and managers for management and supervision of field workers perform control and management.

However, managers are placed in a significantly smaller number than field workers, which creates an area where the manager's control and management is limited. There is a problem in that safety accidents such as falling, overturning and falling occur because the manager's control and management cannot be performed.

In addition, to prevent safety accidents, most construction sites and industrial sites provide safety management education for site managers and field workers, but there is a problem with low effectiveness as it is only a formal procedure.

In other words, safety accidents occurring at construction sites or industrial sites endanger the lives of field workers, and can cause problems such as increase in construction cost, decrease in productivity, and extension of construction period. Accordingly, in addition to the introduction of a systematic and efficient safety management system that can guarantee the safety of on-site workers at construction sites and industrial sites, accidents caused by worker falls, heavy equipment stenosis, and heavy objects, which account for a large proportion of accidents at construction sites, are There is a need for a supplementary risk guidance system that can prevent these problems in advance.

This is to prevent accidental accidents not only for domestic workers but also for foreign workers.

Meanwhile, the warning light device 10 according to an embodiment of the present invention may further include a communication module 150, a control module 170, and a battery module 160, as shown in FIG. Each module may further include a case 40 for accommodating the module that is difficult to be exposed to the outside.

The communication module 150 receives a driving signal from the driving device 20 through a wireless communication network.

In this case, the wireless communication network is an IP-based communication network that provides a large-capacity data transmission/reception service and a data service without interruption through Internet Protocol (IP), or a mobile communication network (2G, 3G, 4G, LTE, 5G), Wibro (Wireless Broadband) network, HSDPA (High Speed Downlink Packet Access) network, satellite communication network and Wi-Fi (Wireless Fidelity) network can be selected according to the environment according to the environment, the communication module 150 It is possible to support data communication through one selected wireless communication network.

The control module 170 receives the driving signal of the driving device 20 received from the communication module 150 , and turns ON/OFF the warning light module 100 , the LED module 120 and the speaker module 140 . control the operation.

The battery module 160 includes each module constituting the device, that is, the warning light module 100 , the LED module 120 , the memory module 130 , the speaker module 140 , the communication module 150 and the control module 170 . ) to supply power.

The battery module 160 may include a conversion circuit for converting the stored power to the input power required by each module, and a protection circuit for blocking abnormal voltage and preventing overload.

The case 40 allows a module requiring protection from external environments such as snow and rain, for example, a communication module 150 , a memory module 130 , and a battery module 130 to be embedded therein.

The case 40 is preferably made of a synthetic resin material, and a reflective plate 41 may be formed on the inner rear surface of the case 40 .

When the case 40 is described in more detail with reference to FIG. 4 , first, in the case of the communication module 150 , the communication chip 151 is mounted on the PCB board 152 inside the case 40 . It is disposed inside the case 40 , and the battery module 160 is also disposed inside the case 40 and is electrically connected to the PCB board 152 to supply power to the PCB board 152 .

As shown in FIG. 4 , the PCB board 152 and the battery module 160 are independently arranged without overlapping areas of the projected areas inside the case 40 . In this case, a separate contact terminal (not shown in the drawings) is formed on the PCB board 152 to be electrically connected to the battery module 160 to extend toward the battery module 160 . The contact terminal is composed of a positive contact terminal and a negative contact terminal so as to be contact-connected to the positive electrode and the negative electrode of the battery module 160 , respectively.

As described above, since the PCB board 152 and the battery module 160 are disposed on the same plane without overlapping regions, the case 40 can be further miniaturized.

The wireless signal generated from the communication chip 151 of the PCB board 152 is transmitted from the inner space of the case 40 to the outer space. As mentioned above, the case 40 is made of a synthetic resin material, and the communication signal passes through the entire surface of the case 40 .

However, the rear surface of the case 40 is a part attached to the lower fixture 50, and when the communication signal is transmitted to the rear surface, the concentration of the communication signal is dispersed by that amount, thereby reducing efficiency.

Accordingly, in this embodiment, a metal reflector 41 is configured on the back side of the case 40, that is, on the surface attached to the structure, so that the concentration of communication signals can be improved by the configuration of the reflecting plate 41 will become That is, a high-strength communication signal is transmitted.

The case 40 is made of a synthetic resin material to allow a communication signal to pass therethrough. In the case of the case 40 made of an existing aluminum material, a transmission portion that allows a separate communication signal to pass through is further configured, and in case of fire, etc. , there is a problem in that the outside air is transmitted to the communication chip 151 as it is and is easily exposed to deterioration. Accordingly, in the present invention, the case 40 is made of a synthetic resin material.

Specifically, the case 40 of this embodiment is formed by a composition comprising polypropylene resin, oxabromophenyl ether, isionate, a heat stabilizer, an inorganic filler, a rubber filler, dioctyl terephthalate, and a foam remover. do.

The oxabromophenyl ether is added to improve flame retardancy. However, when only oxabromophenyl ether is added, flame retardancy is provided, but due to the generation of toxic chlorine gas during combustion, it is harmful to the human body and may cause environmental pollution problems. Accordingly, the composition is to further include itionate.

The itionate is to promote decomposition of chlorine generated in a fire by decomposition and to be immobilized into solid zinc chloride through hydrogen chloride. That is, the oxabromophenyl ether is added to improve the flame retardancy in the case 40, and chlorine gas that may be generated by the oxabromophenyl ether in the event of a fire is immobilized to make it harmless.

The heat stabilizer is for improving heat resistance. As the stabilizer, tribasic lead sulfate, dibasic lead phthalate, barium stearate, and the like can be applied.

And the case 40 is to protect the internal modules including the communication module 150 against external force, and of course it must have strength and impact resistance. In order to improve the strength and impact resistance, inorganic filler and rubber filler are used. to add more.

The type of the inorganic filler is not limited, and examples thereof include mica, walrustonite, clay, silica, calcium carbonate, and metal hydrate. In addition, the type of the rubber filler is not limited and, for example, SBR and the like may be applied.

Dioctyl terephthalate is further added to the composition, and the reason for the addition of dioctyl terephthalate is the impact of the stretching even when the paste is continuously stretched in the process of freezing and thawing due to the material properties that do not lose elasticity even at low temperatures. The dioctyl terephthalate is relieved to improve resistance to cracking in winter, etc.

That is, if the paste freezes and thaws repeatedly at low temperatures, cracks may occur in the paste due to repeated expansion and contraction. It becomes possible to control abnormalities such as

In addition, in the present invention, Psychos is further added as a viscous agent. It is reasonable that Psychos is applied alone or mixed with other viscous agents. The reason for using Psychos as a viscous agent is not only to improve the viscosity between the compositions, but also to control the freezing of water droplets deposited on the outer periphery of the case 40 in winter. to increase speed.

When the formation of ice on the outer periphery of the case 40 is repeated, tension and compression are repeated in the case 40, which is a factor that reduces durability due to fatigue, so that Psycos is further added to the composition to function as a viscous agent The purpose is to control the formation of ice while at the same time allowing this to occur.

Preferably, the composition comprises 1 to 5 parts by weight of oxabromophenyl ether, 0.1 to 2 parts by weight of an ethionate, 0.01 to 1 parts by weight of a heat stabilizer, 1 to 5 parts by weight of an inorganic filler, based on 100 parts by weight of the polypropylene resin, It is reasonable to include 1 to 5 parts by weight of a rubber filler, 0.5 to 3 parts by weight of dioctyl terephthalate, 0.01 to 0.1 parts by weight of a bubble remover, and 0.01 to 1 parts by weight of psicose.

Meanwhile, the control server 30 communicates data with the warning light device 10 through a wireless communication network, and collects status information of the warning light device 10 for each set time according to the operation and state of the warning light device 10 . The on-site risk guidance situation can be monitored remotely.

The control server 30 receives and stores status information from the warning light device 10, wherein the status information may be a resistance value of each module constituting the device, and the control server 30 measures from each module. and analyzing the received resistance value to determine whether there is an abnormality.

In addition, the control server 30 receives and stores the status information according to the ON/OFF operation together with the identification information of the warning light device 10, so that the danger guidance situation for each zone due to the operation of the warning light device 10 in the construction site. can be monitored.

The monitoring information of the control server 30 is displayed as an image through the manager terminal 300 so that the manager can easily check it.

The manager terminal 300 is a terminal to which access is granted from the control server 30 and may be a fixed terminal such as a desktop or a mobile terminal having mobility including a smart phone, a tablet, and the like, and the administrator's command It includes an input unit for inputting , and a display unit for outputting and displaying a monitoring image.
