Abstract

An alarm output device according to water pressure and diving time is disclosed.

Description

[0001] The present invention relates to a warning device for water pressure and diving time,

The present invention relates to a warning output device according to hydraulic pressure and diving time. More particularly, the present invention relates to an alarm output device according to water pressure and diving time, which measures water pressure using an FSR sensor and changes a danger indication of an LED according to a user.

With the recent development of the industrial society, the work of installing underground facilities (pier construction, submarine tunnel construction) requiring high technology has been frequently performed.

In addition, the number of divers or divers who are engaged in harvesting shellfishes such as tortoise shells is gradually increasing, and the working water depth is gradually increasing for profitability review.

Especially, in the case of sea-diving women who do not have safety equipments in the sea, death accidents are increasing because they are checked in a subjective way by long-term experience. Also, in the case of divers who submerged in the deep sea, they may lose their lives after diving in excess of the dive function time.

In order to prevent this, there is a range of safe water pressure and restriction of diving time according to water pressure. However, due to the absence of the intuitive module, there is not a decrease in the number of diving related occupations.

In addition, when exposed to high water pressure for a long time, experts in the field may also suffer accidents due to poor judgment.

In recent years, the incidence of waterborne diseases due to diversification of economic leisure and leisure sports has been increasing due to SCUBA (Self-Contained Underwater Breathing Apparatus) diving and special diving related to military purposes. Diving bottles are closely related to depth of diving and residence time. Normally, the user views the water pressure detector worn on the wrist or body part to recognize the current diving depth (water pressure).

Currently, ordinary daughters do not use hydrostatic measurement and alarm modules, and only professional divers or divers use special equipment or special watches. However, such a conventional apparatus is disadvantageous in that it is difficult for general users to use in terms of price.

In addition, there is a disadvantage in that the present state can not be clearly known in a state where the judgment ability is deteriorated at a high water pressure due to lack of a clear function of notifying the danger.

On the other hand, the FSR (Force Sensing Resistor) is a polymer film that generates a decreasing resistance when the force is increased on the surface of the sensor. As compared with the conductive rubber, there is almost no electric hysteresis. Compared with Piezo Film, FSR has little effect on vibration and heat, and it is cheap in price.

In addition, the FSR has its own resistance value, which is inversely proportional to the magnitude of the force applied to the active region. That is, as the force increases, the resistance value decreases. And this reduced value has linearity.

Therefore, it is necessary to warn the danger of water pressure at the time of diving using the characteristics of the FSR, and to provide a competitive apparatus in terms of cost.

The output unit 300 intuitively displays the safety using a green LED at a water depth of 0 to 15 m when the user is a general user such as a maid or a civilian, and if the water depth is more than 15 m, It can indicate a danger.

The LEDs of the output unit 300 are basically turned on, and each time the depth of the water is further increased by 5 m, one additional LED may be further turned on.

The output unit 300 can display the maximum allowable time according to the water depth by LED when the user is an expert diver.

More specifically, when the user information is a general user, the calculating unit 210 calculates the risk according to a predetermined depth by using the FSR sensor, and when the user information is the professional diver, The risk can be calculated according to the predetermined maximum allowable diving time.

Next, the low pass filter 220 can filter the voltage calculated using the FSR sensor.

Next, the unit change unit 230 may change the voltage filtered by the low-pass filter unit 220 in units of force.

At this time, since the FSR sensor has a nonlinear characteristic, it is possible to use the linearization theory which makes a linear equation according to the range using Equation (1). Further, the value of the force can be changed to the hydraulic pressure value using Equation (2).
