Description

Wearable Safety Status Notification and Management Device

The present invention relates to a wearable safety status notification and management device having a light emitting unit controllable according to the concentration of harmful gases.

A safety accident refers to an accident that causes damage to people or property due to lack of safety education, violation of safety rules, or carelessness in a place where danger may occur.

Despite the spread of safety education and safety equipment, safety accidents occur in many places every year, and some safety accidents in particular lead to serious accidents that kill lives. In particular, safety accidents at industrial sites rather than daily life are often directly related to life, and among them, suffocation accidents are very dangerous safety accidents with a mortality rate of 50% when they occur.

90% of suffocation accidents in confined spaces are reported as human resource accidents, which are caused by structural and cost issues in the industry related to confined spaces. Safety accidents are mainly caused by worker's uncomfortable thinking and manager's poor management, but the lack of functionality of existing safety equipment to prevent suffocation accidents in confined spaces is also one of the important direct reasons.

For example, in the existing work in a closed space, the oxygen concentration in the closed space to be worked is measured before work, and when work is possible, the work is often performed while wearing a portable oxygen concentration meter. In this case, when the situation changes suddenly during work and leaks of harmful gas occur, the oxygen concentration measurement method tells the worker that the concentration of the harmful gas has risen to a degree that is harmful to the worker even though the oxygen concentration is not dangerously low. There is a problem that cannot be informed. In addition, conventional oxygen concentration meters are mostly worn on the user's work clothes, and since there are many methods of notifying the danger situation by sound, it is difficult for the worker to intuitively recognize the danger, and in particular, there is a problem that an alarm is buried in the work noise.

The LED may control the light emission intensity, and the light emitting units 120 and 230 may further include a transparent or colored window 140.

The control unit 210 is electrically connected to the light emitting units 120 and 230 to control color change, illuminance, and on/off of the light emitting units 120 and 230 based on the concentration of the harmful gas.

For example, when the concentration of the harmful gas exceeds a predetermined standard, the operator determines that it is dangerous and controls the power of the light emitting units 120 and 230 to emit light. The control unit 210 may determine the risk of the harmful gas concentration measured by a preset program. Hazardous gases that may cause direct danger to workers can be judged to be dangerous by comparing their concentration with a preset standard, or even if there is no direct risk, even if there is a risk of lowering the concentration of oxygen in the atmosphere, it can be judged as dangerous. have. If oxygen is less than 18%, it may adversely affect the health of the worker, and thus the light emitting units 120 and 230 may be controlled to instruct the worker to evacuate or ventilate.

When the concentration of a specific component in the atmosphere increases, the proportion of oxygen is relatively reduced. Therefore, the light emitting units 120 and 230 may be controlled by detecting this and determining the risk.

Alternatively, when the light emitting units 120 and 230 support a plurality of light emission, the control unit 210 emits light of the light emitting units 120 and 230 in different colors according to the type of harmful gas, thereby varying the degree of risk to the operator. You can make it aware. Alternatively, it is possible to control the flicker of the light emitting units 120 and 230 or differently control the illuminance of the light emitting units 120 and 230 according to the harmful gas concentration information.

The communication unit 220 may support a short-range wireless communication method such as Bluetooth and ZigBee, or a long-distance wireless communication method such as LTE and microwave communication, and the communication method is only an example and is not limited to a specific communication method.

The control unit 210 may communicate with a separate harmful gas concentration meter or a central control center through the communication unit 220.

For example, the wearable safety status notification and management device does not cause inconvenience to work because reducing the weight due to the nature of the mounting location, the additional harmful gas that can be held on the operator's buckle or the harmful gas concentration measured by the oxygen concentration meter Alternatively, oxygen concentration information may be received through the communication unit 220. Alternatively, if the current concentration of harmful gases in the work environment is not high, but if the central control center recognizes the possibility of deterioration of the work environment such as collapse of the periphery in advance, a danger signal is transmitted to the communication unit 220 through long-distance wireless communication and a wearable safety status notification And the control unit 210 of the management device may control the antiseptic and instruct the operator to evacuate in advance.

Of course, the wearable safety status notification and management device further includes a sensor that can directly measure the concentration of harmful gas, and the sensor may measure the concentration of harmful gas or oxygen in real time and transmit it to the control unit 210.

The power supply unit 240 supplies power to the light-emitting units 120 and 230, the control unit 210, and the communication unit 220, and can use a battery or a battery as a power supply source. It can also perform the function of distributing to the module.

The wearable safety status notification and management device may include an acceleration sensor that detects acceleration and inclination information, and the controller 210 may determine the fainting of a worker using acceleration and inclination information extracted from the acceleration sensor.

The controller 210 may control the acceleration sensor to monitor whether a worker faints in real time, and when the worker's fainting is detected, it may notify a dangerous situation to the central management center through the communication unit 220.

In addition, even when the concentration of harmful gas is low, the operator may faint in a separate accident. In this case, the control unit 210 also controls the light emitting units 120 and 230 to emit light to prevent or prevent the operator from losing consciousness. It can help recovery, and there is an effect that can help the rescue of workers in the subsequent rescue work.
