Description

Smart hard hat

The present invention relates to a helmet to be worn on the head to improve the safety of the worker in various industrial sites, and more specifically, to take a picture and real-time image information of the site situation where the worker is located in the construction site or fire site, etc. By transmitting the information to accurately recognize the work site from the outside, it is possible to detect various dangerous situations such as gas leakage, heat generation or vibration in the field, and to respond promptly. When it occurs or is located in a dark place relates to a smart hard hat that can easily determine the location of the worker.

As is well known, various industrial sites such as construction sites or fire sites work in unsafe structures, so not only fall and fall accidents occur, but also many safety threats such as falling objects or flying objects are flying. Due to the factors involved, it is mandatory to wear protective equipment such as hard hats to ensure the safety of workers.

Such a hard hat is to protect the most important head of the body from falling, falling or colliding with an external object of the worker. The shock absorbing material is generally provided in the body of a roughly hemispherical synthetic resin and fixed with a chin strap. have.

However, in actual workplaces, workers often avoid wearing the helmet because it is cumbersome and the work efficiency is reduced while recognizing that such a hard hat is an important equipment to protect their safety. As a result, industrial accidents caused by non-wearing helmets are increasing day by day.

In fact, many of the accidents caused by not wearing a hard hat at the construction site are reported to greatly reduce the risk of injury by simply wearing a hard hat.

Therefore, in order to reduce the accidents caused by the non-wearing of hard hats, it is necessary to accurately grasp whether the worker wears the safety protective equipment correctly in the industrial field and effectively manage it.

By the way, such a normal hard hat merely serves to protect the wearer's head from the impact as much as possible, for example, if the accident is confused or incapable of movement due to an accident such as the impact can no longer protect the accident. There is no problem.

This means that it can not contribute to the prevention of secondary casualties, which can occur due to the lack of prompt response to the accident.Therefore, it is insufficient to function as a safety protective device worn at the expense of various risk situations. Do.

On the other hand, to solve the problem of such a general hard hat, Korean Patent No. 10-1463337 has a smart module integrated image, lighting, various gases, temperature, location information and collision information and alarm on the outer top of the hard hat It is equipped with a smart safety module that can improve the safety and convenience of the helmet.

However, since the smart module is fastened by bolts by forming a protruding block on the outer top of the hard hat, the smart module has to protrude substantially to the upper side of the hard hat, which may limit the worker's behavior. Of course, there is a high possibility of causing a safety accident.

That is, when the wearer moves or works, the smart module protruding to the upper side of the hard hat hits or is caught by an external structure, which may cause the operator to fall or fall.In this case, the setting position of the smart module is changed so that the image of the work site is changed. Accurate shooting and transmission also becomes difficult.

In addition, even though the required sensors such as gas sensors and thermal sensors may be different according to the work site, various sensors are all concentrated. Therefore, various sensors not necessary for the work site are not necessary and the configuration is very large. You have to have a complicated and complicated operating algorithm. This is likely to cause a malfunction.

And because the worker does not have a means to determine whether the helmet is wearing the helmet firmly in the field, it is not enough to prevent the occurrence of the accident due to the wearing of the safety helmet as well as the function of the smart module.

Such specific features and other advantages of the smart helmet of the present invention will become more apparent from the following description of the preferred embodiment with reference to the accompanying drawings.

1 to 4, the smart hard hat 1 according to the present invention is equipped with a hard hat 10 to be worn on the operator's head and the outer periphery of the hard hat 10, information on the situation of the work site and the state of the worker, etc. The smart module 20 and the safety helmet 10 for detecting and transmitting the chin strap 30 for binding to the wearer is configured.

The hard hat 10 has a configuration similar to that of the known one. That is, it consists of a substantially hollow hemispherical shape in which a shock absorber (not shown) and a hair band are mounted in the impact resistant synthetic resin body.

Fixing tabs 11 for mounting the smart module 20 are protruded on both outer peripheries of the opening of the hard hat 10, and the fixing tabs 11 have connectors 21 of the smart module 20 described later. The coupling slot 12 to be fitted is penetrated in the longitudinal direction.

Smart module 20 is formed in a substantially U-shape corresponding to the appearance of the hard hat 10, by being elastically fitted to the coupling slot 12 formed on the fixing tab 11 of the hard hat 10 on both bottom ends. Each of the connectors 21 for integrally mounting the smart module 20 to the helmet 10 is protruded.

As shown in FIGS. 5 and 6, the connector 21 is provided with a pair of elastic hooks 21a arranged at intervals and caught by the lower end of the fixing tab 11 of the helmet 10, and these elastic hooks ( It is located between the 21a) has a chin strap ring 21b integrally bound to the chin strap 30, respectively. The jaw strap ring 21b is configured to be longer than the elastic hooks 21a by a certain length in order to bind the jaw strap 30 so as to be properly exposed to the coupling slot 12 of the fixing tab 11.

Smart module 20 of the present invention is provided with information sensing means to grasp various information about the work site and the worker. Various devices may be used as the information detection means, for example, a camera 22, a danger sensor, an alarm buzzer, an emergency lamp 23, a wireless communication module, and a jaw strap wearing detection means may be adopted. A battery (not shown) for operation is provided together.

The camera 22 is located in front of the helmet 20 so that the front of the worker can be photographed in real time, and captures the field situation corresponding to the operator's field of view in real time, and transmits to the situation room through a wireless communication module.

The risk sensor is used to detect various dangerous situations that may occur in the workplace, for example, a G sensor for detecting an abnormal condition of an operator, a gas sensor for detecting a toxic gas, a thermal sensor for detecting a fire, and a structure. Vibration sensor for detecting whether or not collapse can be made. The detection signals of these risk sensors are also immediately transmitted to the situation room through the wireless communication module.

The alarm buzzer promptly informs the worker and the surrounding dangerous situation by emitting an alarm sound according to a detection signal such as a danger sensor or a jaw strap wearing detection means.

Emergency lamps make it easier to determine the location of a worker by illuminating the environment when the worker enters a dark place or by flashing when the operator is in an emergency situation, such as being confused or injured due to injury.

For this purpose, the smart module is preferably provided with an ambient light sensor for detecting the ambient light, and the emergency lamp is configured to interwork with the G sensor. In other words, if there is no emergency for a certain time due to an emergency situation, the G-sensor detects and transmits the emergency lamp and blinks.

Jaw strap wearing detection means is to determine whether the worker actually wearing the helmet 10 correctly in the field, it can be configured in various forms. Therefore, it is important to grasp whether the helmet is in a solid wearing state so that the helmet 10 can exert its function beyond simply wearing the helmet 10.

Accordingly, in the present invention, the tuck strap 21b is preferably integrally formed with the connector 21 fixing the smart module 20 to the helmet 10 as described above. It is configured to detect that. To this end, the jaw strap wear detection means is made of a pressure sensor such as a piezoelectric element, for example, to determine whether the helmet 10 is correctly worn by the tension applied to the jaw strap 30 when the jaw strap 30 is attached.

That is, even if the worker wears the hard hat 10, if the constant tension does not act on the chin strap 30, the hard hat 10 is peeled off when the user falls down due to a loose wearing state rather than the right state. Bars that may not be able to grasp whether the wear state with a tension acting on the chin strap (30).

It is preferable that the detection signal of the jaw strap wearing detection means also transmits an alarm sound to an operator through an alarm buzzer while transmitting to a situation room through a wireless communication module.

On the other hand, the smart module 20 of the smart helmet (1) of the present invention is preferably composed of a smart module main body 24 and the sensing module 25 to take a configuration capable of mutual coupling and separation. Accordingly, male and female connection connectors 26a and 26b are provided at the coupling portions of the smart module main body 24 and the sensing module 25, respectively.

This is due to the fact that the types of risk detection sensors required according to the characteristics of various industrial sites may be different, and there is no need to provide a number of unnecessary risk detection sensors at once.

Therefore, the smart module 20 of the present invention is provided with a plurality of sensing modules 25 each having at least one different risk detection sensor therein, and easily replaced with a sensing module 25 suitable for the site according to the characteristics of the work site. Can be used.

In this case, not only the configuration of the smart module 20 is very simple, but also the sensing algorithm is extremely simplified to minimize the risk of malfunction, and to reduce the weight of the smart hard hat 1 and to minimize the consumption of the battery. do.

And on one side of the smart module body 24, as shown in FIG. 7, the display unit 28 for visually displaying the switch 27 for turning on / off the power of the smart module 20 and the remaining amount of the battery, etc. May be provided together.
