Description

SAFETY MANAGEMENT SYSTEM

The present invention relates to a safety management system, and more particularly, to a safety management system capable of preventing safety accidents in advance and managing safety education for accident-causing workers.

In general, construction sites use heavy equipment to perform work, and since workers perform work through front observation from the cab of the heavy equipment, most human accidents occurring during heavy equipment operation occur at the rear of the heavy equipment.

In order to prevent such a safety accident, recently, a camera is attached to the rear of the vehicle body of heavy equipment, and the image captured by the camera is displayed in the cab so that the driver can check the situation behind.

However, when only the rear monitoring camera is installed in this way, it is not easy to check the rear situation while driving because the heavy equipment itself is relatively large, and a more efficient method is required due to the blind spot existing around the vehicle body.

In this regard, the heavy equipment approach monitoring system for construction of Patent Registration No. 10-1322201 includes a PIR (Pyroelectric Infrared Ray) sensor that detects the approach of a human body, and an ultrasonic sensor that detects the approach distance of an object using ultrasonic waves returned from the object. a plurality of sensor units provided; a main control unit that processes a signal output from the sensor unit to determine whether a human body or an object approaches, calculates an approach distance, and performs corresponding control; an alarm speaker for outputting an alarm sound to the outside of the vehicle body when a human body approaches under the control of the main control unit; and a display device installed in the cab of the heavy equipment and outputting a human body or object approach detected by the main control unit on a screen.

However, this conventional technique has a disadvantage in that it is difficult to accurately detect the presence or absence of workers around heavy equipment because the accuracy of monitoring at the construction site is lowered depending on external factors such as dust and weather conditions in the workplace.

In other words, it is extremely difficult to detect a worker through image reading or infrared or ultrasonic sensing when considering the activity characteristics of workers who carry various construction equipment or tools, or bring or transport work materials.

In the present invention, it is preferable that the management server provides the radar with the operating range corresponding to the type of the heavy equipment.

In the present invention, it is preferable that the radar is a Frequency Modulated Continuous Wave (FMCW).

In the present invention, the radar includes: a wave transceiver for transmitting a predetermined wave signal in the operating range and receiving the reflected wave signal; a data comparator for comparing the data output from the transceiver with the human body characteristic data; and a result transmission unit for transmitting the output signal of the data comparison unit to the management server.

In the present invention, further comprising a terminal worn by the worker, the management server includes: a notification unit for transmitting a notification signal to the terminal in response to the output signal of the comparison unit; and a processing unit for receiving the corresponding worker information from the terminal of the worker receiving the notification signal, counting the number of times of non-compliance with the safety rules of the corresponding worker, and determining whether to perform the safety education.

In the present invention, when the number of non-compliance exceeds a predetermined number, it is preferable that the management server reports it to a person in charge of performing the safety education.

The safety management system according to the present invention provides the following effects.

The present invention has the effect of preventing safety accidents and personal accidents for the workers in advance by enabling clear monitoring of workers approaching heavy equipment irrespective of the external environment and industry.

The present invention has the effect of systematically managing safety training time for workers and minimizing costs accordingly by selecting workers who continuously fail to comply with safety rules and adjusting the intensity of safety training for the workers.

Referring to FIG. 1, the safety management system is a heavy equipment 100 operating for work at a construction site, a radar 200 for detecting whether a worker has invaded based on the operating range R of the heavy equipment 100, and The radar 200 includes a management server 300 for managing whether or not the worker performs safety education by counting the number of alarm notifications and non-compliance with the safety rules of the worker according to whether or not the worker is infringed.

First, the heavy equipment 100 refers to all mechanical equipment operating for construction work at a construction site, and an excavator is shown as an example here.

For reference, the excavator can be moved to a desired place by using the caterpillar wheel mounted on the lower part of the body, the body can be rotated using the boom configured in the body, and is connected to one end of the arm using the arm mounted in the front. It is possible to move the bucket to the desired position. In this way, the excavator moves to a desired place and performs work at the construction site by moving the bucket to the desired position. As will be described later, the operation range (R) of the excavator, including the movement of the excavator and the movement of the bucket, is stored in the management server 300 and is used as source information of the safety management system according to the embodiment of the present invention.

Next, the radar 200 is mounted on one side of the heavy equipment 100 , and is configured to detect whether or not an operator has invaded based on the operation range R of the heavy equipment 100 .

Here, the radar 200 is an FMCW (Frequency Modulated Continuous Wave) radar as an example, and the FMCW radar irradiates an FMCW signal to an object around the heavy equipment 100 and it is possible to receive a reflected radio signal.

FIG. 2 is a block diagram illustrating an internal configuration of the radar 200 of FIG. 1 .

Referring to FIG. 2 , the radar 200 includes a wave transceiver 210 , a data comparator 220 , a data storage 230 , and a result transmitter 240 .

First, the wave transceiver 210 is configured to transmit the FMCW signal to the operating range R of the heavy equipment 100 and receive the FMCW signal reflected by the object. Although not shown in the drawing, the wave transceiver 210 is connected to the driving unit and sequentially rotates by the driving unit to transmit and receive the FMCW signal for the operating range R.

Next, the data comparison unit 220 is configured to compare the data output from the wave transceiver 210 with the human body characteristic data, where the human body characteristic data means data previously stored in the data storage unit 230 .

The human body characteristic data pre-stored in the data storage unit 230 means data on basic human characteristics such as human shape and motion. That is, human shapes such as a human head, torso, and limbs and human motions such as walking and work are stored in the data storage unit 230 .

Accordingly, the data comparator 220 compares the data output from the wave transceiver 210 with the human body characteristic data stored in the data storage 230 to invade the operator based on the operating range R of the heavy equipment 100 . It is possible to detect whether

Finally, the result transmitter 240 is configured to transmit the output signal S corresponding to the result compared by the data comparison unit 220 to the management server 300 .

Referring back to FIG. 1 , finally, the management server 300 alerts the operator according to whether or not the operator has invaded based on the operating range of the heavy equipment 100 provided by the radar 200 and the operator does not comply with the safety rules. It is a configuration for counting the number of times and managing whether the worker performs safety training.

FIG. 3 is a block diagram illustrating an internal configuration of the management server 300 of FIG. 1 .

2 and 3 , the management server 300 includes a notification unit 310 and a processing unit 320 .

First, the notification unit 310 is configured to transmit a notification signal (A) for informing the operator of the danger in response to the output signal (S) of the result transmitting unit 240 of the radar 200 . Here, the notification signal (A) is transmitted to a siren (not shown) installed on one side of the heavy equipment 100 to make it possible to recognize the danger to the operator who has invaded within the operating range (R), and the terminal is worn by the operator It is also possible to inform the operator of the danger directly by transmitting it to (D). Here, as an example, the notification signal (A) transmitted from the notification unit 310 is transmitted to the terminal (D) worn by the operator.

Next, the processing unit 320 receives the information that the notification signal (A) is output from the notification unit 310 and the corresponding worker information (I) from the terminal (D) that has received the notification signal (A) to ensure the safety of the worker It is a configuration for counting the number of non-compliance with the rules and determining whether to perform safety training according to it.

That is, the processing unit 320 counts the number of non-compliance with the safety rules of the worker through the worker information (I) transmitted from the terminal (D) when the worker continuously invades the operating range (R) of the heavy equipment 100, and If the number of non-compliance with safety rules exceeds the predetermined number, it is possible to report this to the manager to conduct safety training accordingly.

On the other hand, the management server 300 provides the radar 200 with an operation range R defined as a specification for each of the heavy equipment 100 according to the type of the heavy equipment 100 . Here, the operating range (R) defined by the specification may be, for example, the movement of the excavator and the movement of the bucket shown in FIG. 1 .

Accordingly, the radar 200 can transmit a wave signal as much as it corresponds to the operation range R thus provided, and accordingly, the radar 200 can minimize the power consumed in transmitting the FMCW signal, and can be used for transmission and reception and driving. It is possible to optimize the operating efficiency for
