Description

3D monitoring system for confined spaces{SYSTEM FOR 3D-MONITORING OF ENCLOSED SPACE}

The present invention relates to a 3D monitoring system of a confined space.

Specifically, work information including workers who work in a closed space, such as tunnels, large tanks, underground work areas, etc., where there is a possibility of remaining oxygen or harmful gases; Environmental information in the confined space; Etc. so that the manager can monitor it,

By allowing the manager to directly manipulate objects such as work information on the monitoring screen that monitors the information, it is possible to provide convenience so that the elements according to the needs of the manager can be immediately changed and applied during work, and modified accordingly. However, it relates to a 3D monitoring system in a confined space, which can shorten the development time according to the modification by applying a method of adding, modifying, or deleting not regeneration if necessary.

Confined space refers to a place where there is a risk of health damage due to oxygen deficiency or harmful gas, or fire/explosion due to inflammable substances while ventilation is insufficient.

However, it does not necessarily mean only places where the current state is oxygen-deficient or different from harmful gases, and the space where an oxygen-deficient environment can be created during the working process must be classified and managed as a closed space.

In fact, when the oxygen concentration is 16%, breathing and pulse increase, and headache, nausea, and vomiting symptoms occur. And, in 12% of cases, there is a possibility of a fall during work, especially in expensive work places or work using ladders due to inability to support weight.

In addition, when the oxygen concentration is 10%, symptoms such as facial paleness and unconsciousness appear, and in 8% or less, symptoms such as fainting and confusion and death may occur within 8 minutes.

In domestic and overseas industrial/construction sites, asphyxiation and death accidents are increasing every year due to harmful gases during work in confined spaces, but in most confined spaces work, workers have difficulty in recognizing harmful gas information in advance, confirming in advance, and responding quickly afterwards, industrial safety. There is an increasing need to establish a system to comply with health laws and to allow workers in confined space workplaces to work safely.

In addition, it is necessary to establish a platform-based system applicable to industrial/construction sites by establishing an integrated monitoring system such as collection, warning, and control of harmful gases in confined spaces.

In addition, for a work order in a work space where an oxygen-deficient environment may be created during the work process, a system is needed that enables the safety manager to provide information on the hazardous gas situation or oxygen saturation to the worker in advance and give the work order.

These requirements can be solved by applying wireless IoT sensor installation, communication network construction, worker entry and exit information, environmental information collection, data collection and processing, integrated monitoring, and monitoring mobile programs to actual construction sites.

The present invention relates to a 3D monitoring system of a confined space.

Specifically, work information including workers who work in a closed space, such as tunnels, large tanks, underground work areas, etc., where there is a possibility of remaining oxygen or harmful gases; Environmental information in the confined space; Etc. so that the manager can monitor it,

By allowing the manager to directly manipulate objects such as work information on the monitoring screen that monitors the information, it is possible to provide convenience so that the elements according to the needs of the manager can be immediately changed and applied during work, and modified accordingly. However, it relates to a 3D monitoring system in a confined space, which can shorten the development time according to the modification by applying a method of adding, modifying, or deleting not regeneration if necessary.

The 3D monitoring system for a closed space according to the present invention refers to FIG. 1 of the accompanying drawings.

1 shows the configuration of a 3D monitoring system of a closed space according to the present invention.

The present invention according to Figure 1 of the accompanying drawings, the operator terminal; Manager terminal; sensor; And a server;

The operator terminal may be configured in various forms, such as a smart terminal capable of communicating with the operator or a terminal in the form of a separately wearable accessory, but it is sufficient if it can perform the functions described in the present specification.

Therefore, although it may be configured as a normal mobile phone, it may mean a wearable terminal such as a badge or a watch. That is, the operator's terminal should be interpreted in a wide range.

A plurality of the sensors are installed in the closed space to measure the air quality inside the closed space and transmit the measured value to the server.

In this case, communication between the sensor and the server may be performed in an Internet environment, but is not limited thereto.

In addition, the information measured by the sensor may be carbon monoxide (Co), oxygen (O ₂ ), hydrogen sulfide (H ₂ S), methane gas (CH ₄ ), etc. as harmful gas information or oxygen information, and these measured values are sent to the server. Let's go to the sound floor.

In addition, it may include temperature/humidity information and smoke information.

The server processes the work status and environment status into information based on the information received from the worker terminal and the information received from the sensor, generates modeling information based on design information or actual information of the enclosed space, and This function divides the section based on the vector value for the modeling information of.

In addition, when the server exceeds or falls short of a predetermined value (e.g., less than 30 ppm of carbon monoxide, 18 to 23.5% of oxygen, less than 10 ppm of hydrogen sulfide, less than 5% of methane gas, etc.), an alarm is generated and the administrator You can make it verifiable.

The manager terminal receives information from the server and outputs modeling information on the enclosed space, and outputs work information and environment information on the modeling information, but outputs at least two or more of the modeling information. It allows panning or tilting, zooming, and rotating.

For this function, as well as an application program can be installed, the manager terminal may include a smart terminal, a laptop computer, a desktop, etc., in which an application program can be installed.

Looking at an example of a screen output through such a manager terminal, reference may be made to FIG. 2 of the accompanying drawings.

That is, modeling information as shown in [Table 1] below may be generated based on modeling information of the confined space modeled in the server.

To this end, the server may include a modeling information generation module, and may include a partition setting module capable of dividing the modeling information into sections for each predetermined number based on a vector.

Example 1

Example 2

Example 3

At this time, the generated modeling information is configured so that the interior can be projected, and since this function is self-evident in conventional modeling, a detailed description will be omitted.

The information measured through the sensor on the modeling information as described above can be output as an interface element as shown in FIG. 2 of the attached drawing, and the server alarms that an abnormality is detected by the sensor, as shown in FIG. Can be generated so that it can be checked on the screen of the administrator terminal.

To this end, the server may further include an alarm module.

In addition, the server may further include a partition classification module, which serves to distinguish by applying a color to an area divided by the partition setting module on the modeling information.

When an alarm is generated by this divisional classification module, a separate color (hazardous color) can be applied to the corresponding area as shown in FIG. 2.

In the case of such a division division module, as shown in FIG. 2, colors (green and blue) for the division being worked can be automatically applied to the modeling information, and in particular, the color for the job completion and the working space is automatically applied. It can be monitored at a glance.

At this time, in order to determine whether the server is working or the work is completed, the server may further include a work status determination module, and such work status determination module may be determined in connection with the work status application module of the operator terminal.

The work status application module of the worker terminal is that the worker directly generates a signal for the work status through the worker terminal.If the worker terminal is capable of creating and manipulating a smart terminal or PDA, it may be possible based on the input information. If it is a terminal, such as a badge, a button can be implemented and determined through the operation type of the button (one-time operation, two-time operation, quick operation, etc.) or button recognition (work completion button, working button, etc.).

On the other hand, as described above, if the operator terminal is in the form of a badge or the like, it may be configured to enable a pressing operation as shown in [Table 2].

At this time, the configuration referred to as the lower body is the wearing direction.

The operator terminal in the form of a badge according to [Table 2] includes a lower body; An upper body present at a position spaced apart from the lower body by a predetermined distance; At least one spring connecting each of the faces of the lower body and the upper body by bonding, attaching, bolting, etc.; And a button formed to be pressed at a position not interfering with the position of the spring among one surface of the lower body.

With this configuration, it is possible to prevent arbitrary pressing of a button, thereby preventing arbitrary generation of a signal for an operation.

Furthermore, the lower body may be configured such that both ends are inclined so that the cross-sectional shape has the shape of the upper narrow light as shown in [Table 2].

In addition, to one side of the upper body, a pivoting leg that is coupled through a hinge and is rotatable is coupled, and the pivoting leg extends toward the lower body, and the extended end has an inclined shape along the inclined surface of the lower body. do.

In addition, the end of the lower body in the inclined direction is configured to have a more protruding direction than the upper body and the lower body, and in this protruding configuration, the support is coupled through a hinge and a torsion spring, and the support is adjacent to the rotating leg And is formed to have a horizontal direction.

One side of the support is formed with a locking portion protruding.

According to this structure, if the user does not perform an operation to rotate the hinge by a finger on the holding part of the support, the pivoting leg cannot be rotated, and there is no possibility that the button is pressed even if an external force is applied to the upper body. .

In addition, even if the support is configured with only one side as shown in [Table 2], the rotating leg in the direction in which the support is not formed can be rotated and the upper body can be pressed slightly in a direction inclined from the lower body, but at this time, the button is trapezoidal. By configuring it to have a shape, it is to be prevented from being pressed.

Of course, in the case of applying such a color, the server may function automatically through the above-described configuration, but the setting module may be changed manually according to the operation of the administrator in connection with the administrator terminal by further including a setting module of the server. Yes, of course.

Such a manager terminal may include a setting operation module, the setting operation module not only applying the above-described color change, but also applying, deleting, modifying, working, completing work, not working, etc. It functions to allow the administrator to manually operate (see Fig. 4).

In addition, in the case of applying a color according to the work status, as shown in Fig. 5 of the attached drawing, the color classified based on the classification according to the work of the enclosed space (by the administrator, because the work process is different for each type of enclosed space This is because) is guided in a preview format and automatically changed accordingly, so that easy monitoring by the administrator may be possible.

Of course, the above-described functions may also be changed by operation by an administrator. For example, when work is completed but maintenance is required.

In addition, by communicating with a worker terminal, the server may perform time and attendance management according to a worker's commute. To this end, the server may further include a time and attendance management module.

Specifically, in order to monitor the location of the worker, a GPS module is provided in the worker terminal, and the server acquires location information from the GPS module, so that the location of the worker can be determined. It is possible to determine whether or not you are working at the location.

On the other hand, the server can transmit the modeling information generated by the modeling information generation module to the manager terminal as described above to be displayed on the screen of the manager terminal. Therefore, the manager terminal includes the screen operation interlocking module and the output modeling It can be manipulated so that information can be enlarged/reduced (zoom, zoom), tilt control (panning, panning), or rotation (rotate, rotate).

At this time, the manager terminal (or an application program installed thereon) further includes a storage module in the management terminal for fast information processing to store modeling information and use the storage module through periodic communication with the server. Can be shared periodically.

On the other hand, the manager terminal may include a dual output control module capable of outputting the modeling information received from the server on at least two screens.

Accordingly, two or more modeling information can be output on the screen of the manager terminal according to the manager's selection.

In addition, since the dual output control module outputs one modeling information on a plurality of screens, a synchronization function may be provided so that information changed in each screen is automatically applied to other screens.

Such a synchronization function can be prevented from being synchronized according to a user's selection. For this, the dual output control module may have an interface that outputs a message window asking whether or not to synchronize to the user when the dual output is performed.

Referring to FIG. 3 of the accompanying drawings as an example of double output.

As shown in FIG. 3 of the accompanying drawings, as a double output is possible, in monitoring a closed space in three dimensions, it has the advantage of enabling blind-free monitoring.

Each of these dual output screens can be individually panned, tilted, zoomed, or rotated, so that there is no square.

On the other hand, as shown in FIG. 1 of the accompanying drawings, the operator terminal according to the present invention can communicate with a server and a communication repeater, wherein the communication repeater is at least one per compartment divided by the aforementioned compartment setting module. Can be provided.

The operator terminal can communicate with the server through such a communication repeater.

The operator terminal is basically designed to communicate with the server using the closest communication repeater, that is, a communication repeater with the highest signal strength for communication, which functions through a communication module of the operator terminal.

At this time, it is natural that the server, the manager terminal, and the sensor also have a communication module.

However, the communication space is an enclosed space, and the signal strength of the nearest communication repeater may be lower than that of other adjacent communication repeaters due to an error of the communication repeater.

In this case, since the communication module of the operator terminal functions to communicate with the server through the communication repeater with the highest signal strength, even if the signal strength of the nearest communication repeater is weakened, another adjacent communication repeater is automatically used. This makes it possible to communicate with a smooth server with high signal strength.

That is, the communication module of the operator terminal functions to find a communication repeater having the highest signal strength for communication, and this may be to find a communication repeater having the highest signal strength through signal strength analysis at continuous or constant periods.

It is apparent that what has been described with reference to the accompanying drawings in the above is only the main matters of the present invention, and is not limited to the configuration of the accompanying drawings of the present invention as various designs are possible within the technical scope.
