These are safety boots for work.

In the case of the portable detection system, the operator must enter the work space separately from the work tool, and it is cumbersome because it has to go down the ladder.

In addition, if the user enters the work space with the hand held, the user may be exposed to harmful gases in order to measure the oxygen concentration, so the user must take the risk.

The safety boots 10 for work according to an embodiment of the present invention detect a dangerous situation in advance before the user's whole body enters the inside of the work space by using a detection unit and a control unit attached to the safety boots, so that the user is harmed from harmful gases.

Here, the threshold current value is set to 8mA or more and 15mA or less, which is the mantissa current value, which is the maximum current that can be safely dropped from the power source that has been contacted by itself. In case of 15mA or more and 50mA or less, take emergency measures immediately.

When the measured current value exceeds the threshold current value, the second notification message generating unit 580 determines a dangerous situation and generates a second notification message.

Here, the first notification message and the second notification message may generate a warning signal in the warning notification unit of the worker's safety boots, and may be transmitted to an external user terminal to allow the user to detect a dangerous situation through the user terminal.

Accordingly, it is possible to sequentially prevent suffocation accidents and electric shock accidents inside the work space.

It is attached to the safety boots for the user's work, detects oxygen concentration or harmful gas inside the work space into which the user enters, or detects the flow of current on the floor of the work space, and determines whether to notify an alarm according to the detected result a control unit generating a notification message;
Receives a job authentication message for authenticating the user's information and work information from the user terminal, and checks whether a notification message is received from the control unit of the safety boots for work worn by the user to monitor the workspace environment server; including;
The user terminal includes a first user terminal of a first user and a second user terminal moving together with the first user,
The server provides a map to the first user terminal and the second user terminal,
The job monitoring system further comprising a; warning message generation unit for generating a warning message when the location of the work space is different from the job authentication message input from the first user terminal and the second user terminal. 8. The method of claim 7,
The server is
a map providing unit that provides the user terminal with a map from which a location of a work space can be selected; and
Includes; a job authentication message input unit for receiving the location of the work space selected by the user terminal on the map provided from the user terminal and the to-be-executed information input by the user as a work authentication message;
The task information to be performed, the task monitoring system, characterized in that the information including the expected execution time, the work vehicle number, and user login information. delete 9. The method of claim 8,
The control unit is
a first measurement time setting unit for setting a first measurement time for measuring the oxygen concentration or harmful gas when the lower body of the user partially enters the work space;
a first input unit receiving a measured concentration value obtained by measuring the oxygen concentration in the working space during the first measurement time;
a first comparison unit comparing the measured concentration value with a preset threshold concentration value;
a first notification message generator for determining a dangerous situation when the measured concentration value exceeds the threshold concentration value and generating a first notification message;
a second measurement time setting unit configured to set a second measurement time for measuring the current value of the floor of the workspace when the user's whole body enters the inside of the workspace when the measured concentration value is less than or equal to the threshold concentration value;
a second input unit receiving the measured current value obtained by measuring the current value of the floor of the work space during the second measurement time;
a second comparator for comparing the measured current value with a preset threshold current value; and
and a second notification message generator configured to determine a dangerous situation when the measured current value exceeds the threshold current value, and generate a second notification message.
