However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Referring to Figures 1 and 2, the safety management system utilizing an information and communication network at a building work site according to the present invention includes a terminal unit 110, a determination unit 130, and a locking unit 140.

The terminal unit 110 is located outside the work site and transmits the worker's image information to the determination unit 130 through an information and communication network.

The terminal unit 110 includes an image information generation unit 111, a control unit 112, and a display unit 113.

For example, the terminal 110 may be a mobile terminal using the Android operating system or iOS.

The image information generation unit 111 generates image information to determine whether the worker complies with safety rules and transmits the generated image information to the control unit 112.

Specifically, the image information generation unit 111 captures the worker's face to generate facial image information and photographs the worker wearing safety gear to generate safety gear wearing image information and transmits the images to the control unit 112, respectively.

The image information generator 111 may include an image information acquisition device to generate image information. For example, the image information generator 111 may include an RGB camera that captures RGB images as an image information acquisition device.

The control unit 112 outputs the image information to the determination unit 130 and controls the locking unit 140 at the work site according to the discrimination signal for the image information and audio information received from the determination unit 130.

The control unit 112 includes an image information output unit 112a that transmits the image information received from the image information generator 111 to the determination unit 130, and determines the image information and audio information received from the determination unit 130. It includes a discrimination signal receiver 112b that receives a signal, and a locking unit control unit 112c that controls the locking unit 140 depending on whether the worker complies with safety rules.

The image information output unit 112a transmits the image information received from the image information generation unit 111 to the determination unit 130.

Specifically, the image information output unit 112a transmits the received facial image information to the face recognition unit 131 of the determination unit 130, and uses the received safety gear wearing image information to recognize the safety gear of the determination unit 130. It is transmitted to unit 133.

The determination signal receiver 112b receives the result of determining whether the worker complied with the safety rules from the determination unit 130.

Specifically, the discrimination signal receiver 112b determines whether the worker is a permitted worker, determines whether the work site matches the work site where the worker is working, and determines whether the worker wears all safety protective equipment required for work. The determined result is received from the determination unit 130.

The determination signal receiver 112b receives a result of determining whether the worker is an authorized worker from the determination unit 130. That is, the discrimination signal receiver 112b receives a worker confirmation signal when the worker is a permitted worker, and receives a worker fee confirmation signal when the worker is not a permitted worker.

The determination signal receiver 112b receives from the determination unit 130 a result of determining whether the relevant work site matches the work site the worker is trying to enter.

Specifically, the discrimination signal receiver 112b receives a work site confirmation signal when the worker's voice information matches the safety rule pointer confirmation phrase corresponding to the work site, and the worker's voice information corresponds to the safety rule corresponding to the work site. If it does not match the rule-pointing confirmation text, a work site non-confirmation signal is received.

At this time, since the safety rule point out confirmation phrase includes a safety slogan and the name of the work site, the safety rule point out confirmation phrase pronounced by the worker is compared with the safety rule point out confirmation phrase of the relevant work site, and the work site that the worker wants to unlock is determined by the worker. You can determine whether it matches the work site you want to enter.

The determination signal receiver 112b receives the result of determining whether the worker is wearing all safety protective equipment from the determination unit 130.

That is, the discrimination signal receiver 112b receives a safety protective equipment confirmation signal when the worker wears all of the safety protective equipment, and receives a safety protective equipment absence confirmation signal when the worker does not wear at least one of the safety protective equipment.

If the worker complies with the safety rules and the discrimination signal receiver (112b) receives all of the worker confirmation signal, work site confirmation signal, and safety protective equipment confirmation signal, the discrimination signal receiver (112b) grants work permission to the lock control unit (112c). transmit a signal

On the other hand, when the worker fails to comply with at least one of the safety rules and the discrimination signal receiver 112b receives at least one of the worker cost confirmation signal, work site cost confirmation signal, and safety protection equipment confirmation signal, that is, the discrimination signal receiver ( If 112b) does not receive at least one of the worker confirmation signal, work site confirmation signal, and safety protection equipment confirmation signal, the discrimination signal receiver 112b transmits a work permit signal to the lock control unit 112c.

The locking unit control unit 112c outputs a signal for locking or unlocking the locking unit 140 according to the signal received from the determination signal receiving unit 112b.

Specifically, when the lock control unit 112c receives a work permission signal from the discrimination signal receiver 112b, it transmits an unlock signal to the lock unit 140 to unlock the work site.

Meanwhile, when the lock unit control unit 112c receives an operation permit signal from the discrimination signal receiver 112b, the lock unit control unit 112c does not transmit an unlock signal to maintain the locked state of the lock unit 140.

Therefore, only when the worker complies with all safety rules, the lock 140 at the work site is released, allowing unauthorized workers to proceed with work, work at a work site other than an authorized work site, or use safety protection. It can prevent safety accidents such as working without wearing a helmet.

The display unit 113 displays the result of determining whether the worker complied with the safety rules from the determination unit 130.

Specifically, the display unit 113 receives a determination signal received from the determination signal receiver 112b, determines whether the worker is a permitted worker, and determines whether the relevant work site matches the work site where the worker is working. Displays the results of determining whether the worker is wearing all safety protective equipment required for work.

The display unit 113 displays the result of determining whether the worker is an authorized worker through the worker confirmation signal or worker non-confirmation signal received from the determination signal receiver 112b.

The display unit 113 displays the result of determining whether the relevant work site matches the work site where the worker is working through the work site confirmation signal or work site non-confirmation signal received from the determination signal receiver 112b.

The display unit 113 displays the result of determining whether the worker is wearing all the safety equipment required for work through the safety equipment confirmation signal or the safety equipment absence confirmation signal received from the discrimination signal receiver 112b.

At this time, if the display unit 113 receives a safety protective equipment non-confirmation signal and there is safety protective equipment that the worker is not wearing among the safety protective equipment required for work, the display unit 113 detects the unworn safety protective equipment from the discrimination signal receiver 112b. A signal can be received and displayed.

For this purpose, the display unit may include a display device.

Meanwhile, as shown in Figure 3, in the present invention, a box-shaped passage of a certain size is created at the entrance to the workshop, and an air diffusion type blower (BR) is provided at the upper part of the passage, and the air diffusion type blower (BR) is connected to the display unit ( In 113), when it is confirmed that the operator has complied with all safety rules and that the input has started, it is controlled to operate simultaneously with the display signal of the display unit 113.

At this time, the driving time is until there is no detection signal from the human body detection sensor installed in the passage, and when leaving work, it is double controlled so that it is driven simultaneously with the detection of the human body detection sensor.

Thus, while workers pass through the passage, they enter the work site with foreign substances such as dust separated, and they can also shake off foreign substances when returning from work.

In particular, during the summer during work, it can be used as a temporary cooling space for workers to cool off.

Here, the air diffusion type blower (BR) includes a cylindrical fixture 200; A motor shaft 210 fixed to a bearing inside the fixture 200; It is inserted into the fixture 200, and a plurality of block ledges (H1) are formed on the lower surface protruding downward at regular intervals in the circumferential direction, and a locking groove (H2) is formed at the rear end of the block ledges (H1), The lower part has a wing disk 220 provided in an open form; A wing fixture 230 that is inserted from the bottom to the top of the wing disc 220 and is in close contact with the block shoulder H1 and is caught in the locking groove H2; Wings 240 extending from the wing fixture 230; A driving motor 270 disposed on the fixture 200 and fixed to the ceiling fixture 260 by a fixing shaft 250; A rotating sleeve 280 is inserted downward from the top of the drive motor 270 and is rotatably disposed through a bearing, and its lower circumference is screwed to the blade disk 220; A sealing cover (290) covered with the rotating sleeve (280) and its upper end fixed to the ceiling fixture (260); A fixing screw 212 passed through the rotating sleeve 280 and screwed to the motor shaft 210; It includes a lower cover (CV) that is screwed to the lower end of the fixture 200 and seals the lower part of the wing disk 220.

At this time, the drive motor 270 is driven and controlled by receiving commercial power by a controller (CTR), which is electrically connected to the human body detection sensor and display unit 113 described above and according to the detection signal. It is configured to control the driving of the drive motor 270.

In addition, the ceiling fixture 260 and the sealing cover 290 are preferably fixed by a screw fastening method.

In addition, a step is formed inside the rotary sleeve 280 to prevent the drive motor 270 from deviating upward, and the sealing cover 290 also corresponds to the external shape of the rotary sleeve 280. It is molded into shape.

In addition, the reason why the motor shaft 210 is not directly fixed to the wing disk 220, but is assembled and configured to rotate the wing disk 220 through the external rotating sleeve 280 while being idlely coupled through a bearing. This is to prevent the motor shaft 210 from being deformed and malfunctioning when used for a long time because it is difficult to withstand the load of the wing disk 220 equipped with a plurality of blades 240 when the motor shaft 210 is directly fixed.

In other words, it was designed to sufficiently distribute the load while deliberately modifying it to best receive rotational torque.

In addition, this is to prevent the appearance quality from deteriorating.

In particular, the ceiling fixture 260 has the advantage of being easy to install without being limited by the installation location because it can be fixed by hanging on a hanger 262 provided on the ceiling.

In addition, the rotating sleeve 280 is made of 100 parts by weight of polyethylene resin, 6.5 parts by weight of C ₁₈ H ₂₄ N ₂ , 5.5 parts by weight of PPO (POLYEHENYLENE OXIDE), and nonylphenol to ensure durability, heat resistance, moisture resistance, and sound absorption. 5.0 parts by weight of toxilate, 5.5 parts by weight of azelaic acid, 10 parts by weight of guar gum, 5 parts by weight of dimethylbenzylidene sorbitol, 10 parts by weight of HFP (Hexafluoropropylene), 10 parts by weight of sodium fusidate hydrogel, 5 parts by weight of sodium alkylbenzenesulfonate It is molded from a composition of mixed parts.

At this time, C ₁₈ H ₂₄ N ₂ (N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine) prevents thermal oxidation, suppresses discoloration, and enhances durability.

In addition, PPO resin (POLYEHENYLENE OXIDE) is a high-temperature heat-resistant resin. It has electrical insulation due to low moisture absorption (water resistance), excellent dimensional stability, excellent hardness and impact strength, and has the advantage of being lightweight and capable of being lightweight.

In particular, nonylphenol ethoxylate is added to increase flexural strength by increasing occlusion with the resin and provide a surface active function, and especially to obtain an antioxidant effect.

In addition, azelaic acid maintains dimensional stability by suppressing heat shrinkage after molding.

In addition, guar gum increases waterproofing while maintaining tensile strength and has expansion and absorption properties, thereby increasing cushioning properties.

At this time, dimethylbenzylidene sorbitol increases the bonding force between components and prevents the wear resistance of the molded product from decreasing.

In addition, sodium oxide hydrogel is a highly hygroscopic white powder of sodium oxide oxide, and the hydrophilic polymer swells as it contains water to form a hydrogel, thereby forming a three-dimensional network structure and a microcrystalline structure, providing moisture resistance and buffering properties. It is added to enhance moisture resistance, cushioning, and sound absorption.

In addition, sodium alkylbenzenesulfonate has the characteristic of not only strengthening acid resistance, but also strengthening deterioration resistance and increasing chemical resistance.
