Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety equipment wearing promotion system,

An embodiment according to the concept of the present invention relates to a safety equipment wearing incentive system and an operation method thereof, and more particularly to a safety equipment wearing incentive system for encouraging an operator to wear a safety helmet by himself.

Workers at the construction or industrial sites are experiencing a steady increase in the proportion of deaths caused by falls during work. To prevent such accidents, workers are obliged to wear safety equipment.

However, in a construction site, workers often do not wear safety equipment such as a safety helmet due to inconveniences in work, and managers who supervise and supervise workers are placed in a significantly smaller number of workers than workers. Workers are not properly managed to wear safety equipment.

Therefore, despite various factors for safety management such as safety equipment and safety education, there is a problem that workers do not voluntarily wear safety equipment and do not observe the regulations.

Japanese Patent Application Laid-Open No. 10-1725144 discloses a smart helmet which periodically senses a health condition of an operator and generates an output signal so that other workers or a specific manager in the vicinity of the operator can recognize the health status of the operator during the work .

However, the prior art document still has a problem that the worker does not voluntarily wear the helmet.

The control unit 730 generates a stationary state information packet YNP including a measurement unit ID field (measurement unit ID) and a stationary state field (stationary state) expressed in hexadecimal form, and outputs the generated stationary state information packet YNP May be transmitted to the server 500 through the mobile communication module 750 and the network 400 (S360 to S380). The server 500 analyzes the stationary information packet YNP, determines an operation start time or an operation end time of the operator according to the analysis result, and stores the result of the determination in the database in operation S390.

The server 500 stores the work start time or the work end time of each worker with reference to the helmet position of the helmet storage box 700.

 Referring to FIGS. 5 and 6, a method of storing a work start time and a work end time for each worker with reference to a helm position of a safety helmet storage box, and a method for calculating a degree of performance of a safety rule for each worker will be described.

Referring to FIGS. 4 and 5, the server includes a station ID information field YNP including 'T0001' in the measurement ID field (measurement ID) and '25' in the station ID field (station ID) Lt; / RTI > The server can determine whether or not the helmet is mounted by helmet position as shown in Table 1 from the measurement unit ID ('T0001') and the mounting information ('25' = '00100101').

Helmet position (row, column) Whether the helmet is mounted (1, 1) Abandoned (1, 2) Abandoned (1, 3) Stationary (1, 4) Abandoned

The server can judge that the time when the safety helmet is stuck is the start time when the safety helmet is stuck or not, and when the safety helmet is stalled, can do.

The server reads the worker ID (for example, 'M0001') and the name (for example, 'chidoll') corresponding to the helmet position (for example, (1, 2)) with reference to the database shown in FIG. (E.g., '2017-08-10 08:10:12') at which the helmet is released in the job start time field corresponding to the worker ID in the table shown in FIG.

In the present specification, the term "degree of performance of safety rules" means that a worker wears a helmet in a percentage of his / her working hours, and a person who has the highest degree of safety It can be judged. Therefore, the degree of performance of the safety rule can be referred to as the MSP (most safe person) score, and is calculated as Equation 2 below.

[Equation 1]

은 총 작업 시간 동안 작업자의 안전모 총 착용 시간을 의미한다.Herein, the total work time refers to the time from the job start time to the job end time, i denotes the number of times the wearer receives the wearer's time packet received by the server,

Means the length of time the worker wears the helmet during the total working time.

For example, in order to calculate the MSP score of the worker having the worker ID 'M0001', it can be known that the total work time of the worker is '35733 seconds' using the data stored in the database shown in FIG. 6, The total time of wearing the helmet during the working hours of '33121 seconds' is known.

Accordingly, the MSP score of the worker having the worker ID of 'M0001' is '33121 seconds / 35733 seconds * 100 = 92 (%)'.

The server 500 can manage the worker-specific MSP score by day, week, and month. For example, the daily MSP can be managed as shown in Equation (1), and each weekly and monthly MSP can be managed as an average of MSPs.
