Description

On-site manpower monitoring system for safety management

The present invention relates to a technology that enables management and supervision by grasping the status and status of personnel deployed at a disaster accident site such as a fire or an industrial site such as construction and civil engineering, and enabling immediate delivery of necessary measures in the event of a specific matter. will be.

At the site of a disaster such as a fire or an industrial site such as a construction site, a large number of personnel are assigned to perform their respective roles.The manager grasps the status of the personnel on the site, the status of work, and whether there is an emergency, and takes necessary measures in a timely manner. It must be taken, and through this, the assigned task can be performed smoothly while safely managing the manpower.

For this, technologies that can monitor manpower at a disaster site have been proposed, such as Korean Patent Registration No. 10-0800016 (2008.01.25.'Disaster Management Method and System'). However, conventional field manpower monitoring systems have the following problems.

First, it is inconvenient to wear various sensors for monitoring the site situation. In other words, there is a problem in that parts such as temperature sensor and altitude sensor must be worn on the firefighting suit (work clothes) one by one, and if it is manufactured in a form built into the firefighting suit, it is difficult to wash.

In addition, conventionally, a vibration device or a speaker is mounted on clothes or belts to generate vibration or voice in a dangerous situation so that field personnel can evacuate. However, when the site is noisy, there is a problem that there are more cases where vibration or voice is not recognized.

In addition, in order to monitor the situation of field personnel, it is necessary to update the field personnel database stored in the central server from time to time and transmit the necessary field personnel data to the commander's terminal. 6 shows an example in which existing field manpower data is stored. In other words, after establishing a database of field personnel with a standard structure in advance, the sensing information received in real time is updated, and the necessary information is extracted and sent to the relevant commander.

However, in the case of a fire site, not only the personnel in the jurisdiction are employed, but also personnel from adjacent areas are sometimes employed. In other words, it is common to not know at all which crew will be employed at which site, when and which commander will be in charge. Of course, even at the construction site, the input manpower and its size change from time to time according to the work process.

When using an existing standardized database in such a situation where the manpower changes frequently, it is very inefficient to update the sensing information that changes from time to time, and to find and transmit the necessary data of the operator according to the request of the terminal.

For example, suppose that there are 1,000 firefighters nationwide, and only A, B, and C personnel are employed at the fire station. At this time, in order to send the data of the on-site personnel to the commander, the data of 1,000 personnel should be queried to select the data of the personnel A, B, and C that were on-site. However, since the field situation changes rapidly, the data sent to the commander terminal must be updated from time to time, and this complicated process has to be carried out every time. If there are multiple firefighting sites, this process is repeated, which inevitably generates a lot of traffic to the server.

The present invention was conceived to solve the problems of the prior art as described above, and enables a manager to quickly take necessary measures by grasping the status of deployment of on-site personnel and an emergency situation at a site where a large number of personnel are deployed. Its purpose is to provide technology.

A monitoring system for safety management of field personnel according to the present invention for achieving the above object comprises: a user terminal used by field personnel and commanders and generating and transmitting monitoring information; And a relay server that receives monitoring information from the user terminal and transmits it to a specific user terminal; wherein the user terminal is divided into a field manpower terminal used by field personnel and a commander terminal used by a commander, and the monitoring information is It includes GPS information, and the relay server analyzes the GPS information to group field personnel terminals located within a certain radius of the conductor terminal, and then transmits the monitoring information transmitted from the field personnel terminals within the group to the conductor within the group. It can be transmitted to the terminal side.

Here, the relay server may delete the received monitoring information when a group between the field personnel terminal and the commander terminal is not formed.

In addition, a wearable device worn on the user's body and transmitting the collected information to the user terminal side; further comprising, wherein the wearable device connects a communication channel with the user terminal through a short-range wireless communication method and transmits and receives information. Way; An altitude sensor that measures altitude information; And a control means for transmitting and processing the altitude information measured by the altitude sensor to the user terminal through the communication means, wherein the user terminal connects a communication channel with the wearable device or the relay server to transmit and receive information Communication module; A motion sensor for acquiring motion information by detecting a user's motion; A GPS module for obtaining GPS information; A screen output unit that outputs monitoring information on a screen; And an app operation unit that transmits monitoring information including the altitude information, motion information, and GPS information to the relay server, or processes monitoring information received from the relay server to be displayed on a screen through the screen output unit. have.

In addition, the app operation unit of the commander terminal among the user terminals displays a mark representing the field manpower terminal on a screen when the monitoring information is displayed on the screen, and the mark is displayed according to the altitude information, motion information, and GPS information of the field manpower terminal. The display height, motion, or color of can be distinguished and displayed.

In addition, when displaying the height of the mark according to the altitude information of the field personnel terminal, the app operation unit of the conductor terminal among the user terminals calculates the relative altitude difference by comparing it with the altitude information of the conductor terminal and then processes the display. have.

Further, the wearable device further includes a command input unit for inputting an emergency call signal, and when an emergency call signal is input through the command input unit of the wearable device, the emergency call signal is transmitted from the control means to the field personnel terminal. And, the app operation unit of the field personnel terminal transmits and processes monitoring information including the emergency call signal to the relay server, and the app operation unit of the commander terminal transmits monitoring information including the emergency call signal through the relay server. When received, it is possible to notify that the emergency call has occurred by changing the mark of the field personnel terminal that has sent the emergency call signal.

In addition, the wearable device further includes a light emitting means for emitting light of a specific color, wherein the user terminal further includes a key input unit for receiving a user command, and when an escape command is input through the key input unit , The app operation unit of the conductor terminal transmits an escape command to the relay server, the relay server transmits an escape command to the field personnel terminal side consisting of the conductor terminal and the group, and the app operation unit of the field personnel terminal transmits the relay server. When an escape command is received from, the escape command is transmitted to the wearable device, so that light of a specific color may be emitted from the light emitting means of the wearable device.

According to the monitoring system for safety management of field personnel according to the present invention, since a wearable device detachable to the user's body is used, it is easy to wear and release, and it is convenient because it does not affect clothes washing.

In addition, since it is possible to notify an escape command or the like using a light emitting means located within the field of view of the field personnel, it is possible to solve the problem that the escape is delayed without recognizing the guidance voice or vibration due to noise in the field.

In addition, since on-site personnel are displayed on a per-floor basis in accordance with each altitude within the virtual building displayed on the conductor terminal, the status of on-site personnel can be clearly checked. At this time, since the altitude information is not reflected in absolute altitude, but is converted to relative altitude based on the commander's basis, it is efficient in high field conditions, and the error value at the same site is almost constant even if an error occurs depending on the site situation. There is also an effect that the error of the relative value is automatically corrected.

In addition, when storing user's monitoring information in a database, data processing speed is high because it is a method of serially accumulating unstructured data within a group, rather than using pre-built standardized data. In other words, in the case of the standardized data storage method, the data of all personnel was built in advance, and the data of specific personnel was frequently requested and retrieved from the conductor terminal, so the data processing speed was inevitably slow, but the storage method of the database was decided in advance. Data processing can be performed very quickly by applying a method of grouping specific users based on distance from information transmitted by each user without dropping, and then collectively transmitting information in the group to the leader of the group.

The temperature information measured by the temperature sensor 64 is not only used for identifying the temperature of the fire site and preparing for dangerous situations, but also used as data for correcting the measurement information of the altitude sensor 63 that is affected by the temperature. have.

The command input unit 65 is for receiving a user command and may be manufactured with one or more buttons. The user turns on the power of the wearable device 60 through the command input unit 65 and enables communication connection with the user terminals 40 and 50 to be performed, or sends his or her emergency situation to the conductor 92 through his or her emergency button. Let us know and ask for help.

The control means 66 processes the information measured by the altitude sensor 63 and the temperature sensor 64 to be transmitted to the user terminals 40 and 50 through the communication means 61, or power through the command input unit 65. When is turned on, it performs communication channel connection with the user terminal (40,50), or when the emergency button is pressed, the emergency situation notification data is transmitted to the user terminal (40,50) side, or the user terminal (40,50) side When an escape command is received from, the light emitting means 62 is operated to emit light with a specific color. Depending on the implementation, the control means 66 may correct the altitude information measured by the altitude sensor 63 according to the information measured by the temperature sensor 64.

In addition, the wearable device 60 may further include various types of sensors that collect field situation data, such as an acceleration sensor and a gas detection sensor, in addition to the altitude sensor 63 and the temperature sensor 64. And may further include a speaker. In addition, a vibration means may be further included so as to generate vibration together with the operation of the light emitting means 62 when the escape command is received.

User terminals 40 and 50 refer to mobile communication terminals possessed by the user. Here, the user can be divided into a firefighter 91 who is put into the fire site to directly perform rescue and fire suppression, and a commander 92 who commands the firefighters 91 in total. Accordingly, the user terminals 40 and 50 may also be divided into a field personnel terminal 40 used by the firefighter 91 and a conductor terminal 50 used by the conductor 92. The field manpower terminal 40 and the conductor terminal 50 are only given different names so that they can be distinguished according to the user who uses them, and may be substantially the same type of terminal (eg, a smart phone). In addition, the user terminals 40 and 50 may connect to a mobile communication network to transmit and receive information, but may transmit and receive information through a national disaster safety communication network.

In addition, the field manpower terminal 40 and the commander terminal 50 may differ in the installed dedicated application (firefighter application or commander application), but the basic functional configuration is the same, so hereinafter, the field manpower terminal 40 Only the detailed configuration of is described.

The field personnel terminal 40 is a terminal used by the firefighters 91 who are put into the fire site, and connects the communication channel with the wearable device 60 through a short-range communication method such as Bluetooth, and information collected from the wearable device 60 It is provided to collect and transmit the information collected by itself to the relay server 20 side. This field personnel terminal 40 includes a communication module 41, a motion sensor 42, a GPS module 43, a screen output unit 44, a key input unit 45, and an app operation unit 46.

The communication module 41 is provided to connect the wearable device 60 and a communication channel through a short-range wireless communication method and transmit/receive information. In addition, the communication module 41 may transmit and receive data to and from the relay server 20 through a mobile communication network or a national disaster safety communication network.

The motion sensor 42 is for detecting the movement of the firefighter 91 carrying the field personnel terminal 40, and a gyro sensor or an acceleration sensor may be applied.

The GPS module 43 is provided to acquire coordinate information of a current location through a satellite.

The screen output unit 44 is provided to display a user interface according to driving of a dedicated application, and the key input unit 45 is provided to receive a user command. Depending on implementation, the screen output unit 44 and the key input unit 45 may be manufactured in the form of a touch screen.

The app operation unit 46 is provided to control the overall functional configuration for field monitoring. That is, the app operation unit 46 controls functions set according to the dedicated application installed in the user terminals 40 and 50.

For example, when the user terminals 40 and 50 are the field personnel terminal 40, an application for firefighters is installed, and accordingly, the app operation unit 46 collects monitoring information and transmits it to the relay server 20 from time to time. The monitoring information collected and transmitted by the app operation unit 46 is the ID, name, affiliation, and status classification of the firefighter 91 (referring to whether it is the commander 92 or a field crew member), temperature information, altitude information, GPS It may include information, motion information, indoor/outdoor status, communication status information, emergency situation occurrence information, and the like.

Among these monitoring information, ID, name, affiliation, and status are pre-stored by the user directly inputting the application after the first installation of the dedicated application on the user terminals 40 and 50. In addition, temperature information and altitude information are information collected by the wearable device 60 and collected through the communication module 41. In addition, GPS information, motion information, etc. are information collected through the GPS module 43, the motion sensor 42, and the like. In addition, the communication status information is information on whether normal communication with the wearable device 60 is performed through the communication module 41, and the emergency situation information is provided by the user through the command input unit 65 of the wearable device 60. This information is generated when the button is pressed.

In addition, the app operation unit 46 may transmit the escape information to the wearable device 60 when receiving emergency escape information from the relay server 20.

Meanwhile, when the user terminals 40 and 50 are the conductor terminals 50, the conductor application is installed, and accordingly, the app operation unit 46 receives monitoring information from the relay server 20 and then processes the screen output, When 92 inputs a command such as an emergency escape, it is possible to transmit and process the escape information to the relay server 20 side. An example in which monitoring information is displayed on the screen through the conductor terminal 50 will be dealt with again below with reference to FIG. 4.

After receiving the monitoring information from the field personnel terminal 40, the relay server 20 transmits monitoring information to the commander terminal 50 in a location adjacent to the firefighter 91 or to the situation room terminal 10. It is prepared. The relay server 20 may be operated by the Fire and Disaster Prevention Administration, for example, to exchange data with the user terminals 40 and 50 through the national disaster safety communication network, thereby managing fire sites nationwide. This relay server 20 includes a communication unit 21, a control unit 22, and a database 23.

The communication unit 21 is provided for connecting a communication channel with the user terminals 40 and 50 through a mobile communication network or a national disaster safety communication network and transmitting and receiving data.

The control unit 22 processes a series of tasks for analyzing the monitoring information received from the field manpower terminal 40 and transmitting it to the commander terminal 50 of the fire site. For example, the control unit 22 analyzes the GPS information received from the field manpower terminal 40 and the GPS information received from the conductor terminal 50 to detect the field manpower terminals 40 that are active within a certain distance from the conductor terminal 50. It is designated as a group, and the monitoring information in the group is processed so that it is collectively transmitted to the conductor terminal 50.

The database 23 is provided to temporarily store monitoring information transmitted from the user terminals 40 and 50. The process of storing and extracting information in the database 23 is performed by the control unit 22. At this time, the control unit 22 groups the data in an unstructured manner, and when the field situation ends, the data of the group is collectively deleted to secure the capacity of the database 23.

Of course, monitoring information received from the user terminals 40 and 50 may be stored in a separate backup server and used to analyze the status at a later time.

The situation room terminal 10 is a terminal that receives monitoring information from the relay server 20 and outputs a screen, thereby monitoring the situation of various fire sites and analyzing the history or statistics.

The monitoring system according to the embodiment of the present invention described above will become more clear by the monitoring process described with reference to FIGS. 3 to 5 below.

3 is a flowchart for explaining a process of monitoring a field situation using the monitoring system shown in FIG. 1, and FIG. 4 is an example in which the field situation is displayed on a screen on the commander terminal 50 in the monitoring system shown in FIG. FIG. 5 is a conceptual diagram illustrating a process of generating data in an informal manner in the database 23 of the relay server 20 in the monitoring system shown in FIG. 1.

Prior to the description, an application for firefighters is pre-installed in the field personnel terminal 40, and the firefighter 91 inputs information such as a unique ID, name, affiliation, and status classification (firefighter) through the key input unit 45. It is assumed to be in the state. In addition, the conductor terminal 50 is pre-installed with an application for a conductor, and it is assumed that the conductor 92 has entered information such as a unique ID, name, affiliation, and status classification (conductor) through the key input unit 45. do.

After that, when a user (firefighter and commander) who wears the wearable device 60 and carries the user terminals 40 and 50 moves to the fire site and turns on the power of the wearable device 60, the communication means of the wearable device 60 (61) and the communication module 41 of the user terminals 40 and 50 are automatically connected by a short-range communication method such as Bluetooth <S305>. When the power of the wearable device 60 is turned on, the light emitting means 62 may emit blue light indicating that it is in a normal state.

When the wearable device 60 and the on-site personnel terminal 40 are connected to the communication channel, the fire brigade 91 is inputted to each site to carry out rescue and fire extinguishing activities, the app operation of the on-site personnel terminal 40 The unit 46 transmits the data collected by itself and the monitoring information collected by the wearable device 60 to the relay server 20 side <S310>. Likewise, the app operation unit 46 of the conductor terminal 50 transmits the data collected by itself and the data collected by the wearable device 60 to the relay server 20.

Monitoring information transmitted from the app operation unit 46 of the user terminals 40 and 50 to the relay server 20 is ID, name, affiliation, status classification, command status, temperature, altitude, GPS, movement, indoor/outdoor status, communication It may be status, emergency information, etc.

In the case of ID, name, affiliation, and status classification, this is information that was first entered and stored after installing a dedicated application.

Command authority refers to whether the command authority has been granted on-site.In the case of the commander terminal 50, the command right is basically granted by installing the application for the commander, and in the case of the field manpower terminal 40 used by the firefighter 91, the command authority is Not granted.

Temperature and altitude information is collected by the wearable device 60, and information such as GPS information, motion information, indoor/outdoor status, etc. is collected and transmitted by the user terminals 40 and 50. In addition, the communication status information is information on whether a normal communication channel is connected between the wearable device 60 and the user terminals 40 and 50, and the emergency situation information is by pressing the emergency call button through the command input unit 65 of the wearable device 60. It is information on whether the emergency call signal was input by pressing.

Upon receiving monitoring information from the user terminals 40 and 50 through the communication unit 21 of the relay server 20, the control unit 22 temporarily stores the monitoring information in the database 23. Thereafter, the control unit 22 analyzes the received information of each of the firefighters 91 and the commanders 92 and checks the group <S315>. Group confirmation refers to the first grouping of firefighters (91) and commanders (92) who are performing fire suppression work within a certain radius. If a group is already established, the commander (92) who needs to send additional received information It encompasses the process of verifying.

That is, the controller 22 checks the GPS information received from the conductor terminal 50 and the GPS information received from the field personnel terminal 40, and groups the field personnel terminals 40 located within a certain radius from the conductor terminal 50. do. For example, the control unit 22 may group field manpower terminals 40 located within a radius of 300 meters around the conductor terminal 50. Referring to (a) of FIG. 5, it can be seen that one fire site occurs and one commander 92 and two firefighters 91 are grouped together.

Thereafter, the control unit 22 of the relay server 20 transmits the monitoring information collected from the user terminals 40 and 50 of the fire site in which the grouping has been made to the conductor terminal 50 of the group <S320>, and the conductor terminal ( The app operation unit 46 of 50) organizes the monitoring information received from the relay server 20 and outputs it through the screen output unit 44 to display the situation <S325>.

For example, when one fire site occurs as shown in (a) of FIG. 5, the monitoring information of firefighters A and B is transmitted to the commander terminal 50 of commander 1. If three fire sites occur as shown in Fig. 5(b), the information of firefighters A and B within a radius of 300 meters is transmitted to the conductor terminal 50 of conductor 1, and the conductor terminal 50 of conductor 2 The furnace transmits information of firefighters C, D, E, and F within a radius of 300m, and the commander terminal 50 of commander 3 transmits information of firefighters G, H, I, J and conductor 4 within a radius of 300m. To transmit.

On the other hand, if only the fire brigade 91 or the commander 92 is located at a specific fire site, the monitoring information transmitted to the relay server 20 is temporarily stored in the database 23 because a group cannot be created. It is immediately deleted.

In addition, when a new firefighter 91 enters the vicinity of the commander 92 of the group after the group has already been formed, monitoring information is accumulated and matched to the group in a serial manner. That is, the state of the newly added firefighter 91 is immediately reflected on the commander terminal 50 and displayed on the screen.

In addition, when the commander 92, who has been given command authority, terminates the dedicated application at the fire site in which the grouping has been performed, the entire data of the group is automatically deleted from the database 23 of the relay server 20.

4 shows an example of a screen output in which the status of the firefighters 91 are displayed on the commander terminal 50. That is, the conductor 92 can check the ID, location, movement state, indoor/outdoor status, temperature, etc. of the fire brigade members 91 through the conductor terminal 50.

Among these, the movement state may be displayed by varying a mark representing the firefighter 91, for example, the movement of a character. That is, the app operation unit 46 of the commander terminal 50 displays the character walking in the case of the firefighter 91 in motion through the monitoring information received from the relay server 20, and the fire brigade without motion In the case of the circle 91, it is marked so that the character is in a stationary state. Through this, when the conductor 92 checks a member who has not moved for a long time, it is possible to take quick relief measures.

In addition, whether indoors or outdoors can be distinguished and displayed by the color difference of the character. That is, the app operation unit 46 of the commander terminal 50 displays the character in black in the case of the firefighter 91 indoors through the monitoring information, and displays the character in white in the case of the firefighter 91 outdoors. can do. Through this, the commander 92 can intuitively check whether there are any crew members remaining in the building after the fire suppression is over.

Meanwhile, the positions of the firefighters 91 may be displayed for each floor using altitude information measured by the altitude sensor 63. For example, when a fire occurs in a building, different firefighters 91 are put on each floor to simultaneously extinguish a fire. At this time, which fire brigade (91) was put on each floor is displayed on the commander terminal (50).

At this time, the altitude information collected by the field manpower terminal 40 and transmitted to the conductor terminal 50 through the relay server 20 is an absolute value, but when the screen is displayed on the conductor terminal 50, the conductor 92 is located. It is converted to a relative height according to the altitude of and displayed.

That is, the conductor 92 may input the number of floors on which it is currently located through the key input unit 45. For example, it is possible to input that the conductor 92's own altitude information is 10 meters, and that the number of floors of the conductor 92 is 3 floors. In this case, the App Operation Department 46 regards the firefighter 91 with an altitude of 7.5 meters as one floor below the commander 92 and displays it on the second floor, and displays the firefighter 91 with an altitude of 15 meters. In the case of ), it is considered to be two levels above the conductor 92 and is marked on the 5th floor.

Of course, altitude information collected as an absolute value may be displayed on the commander terminal 50 as it is, but if the fire site itself is in a high area from sea level, the absolute altitude indication rather confused on the command of the site. Therefore, it is efficient for on-site management to display the screen in consideration of the relative altitude difference based on the position of the conductor 92 himself.

In addition, there may be an error in the measured value of the altitude sensor 63 depending on the site situation. However, at the same site, since the error of the altitude sensors 63 of each of the firefighters 91 and the commander 92 will be the same, the relative difference is almost constant. Therefore, if the relative height is displayed based on the altitude of the conductor 92, the error of the altitude sensor 63 itself can be corrected.

In addition, the altitude information may have an error due to the temperature of the site. Therefore, the app operation unit 46 of the field manpower terminal 40 compares the altitude information collected from the altitude sensor 63 with the temperature information collected from the temperature sensor 64 and corrects the altitude information according to a preset setting. It can also be transmitted to the relay server 20 side.

On the other hand, when the altitude change of the fire brigade 91 is insignificant, an error may occur in the display of the number of floors. In this case, the app operation unit 46 of the commander terminal 50 may change the number of floors display by considering the altitude information and motion information of the firefighter 91 together. For example, when the floor division is set to 2.5 meters, if the altitude change occurs less than 2 meters, it may be unclear whether the number of floors of the firefighter 91 should be changed. That is, when a change in altitude of less than 2 meters occurs, the app operation unit 46 checks whether an upward or downward acceleration change has occurred through the information of the corresponding operator's motion sensor 42, and then determines the change between floors and displays the screen. You can do it.

On the other hand, when a specific firefighter 91 presses the emergency call button through the command input unit 65 during fire suppression, emergency situation information (emergency call signal) is included in the monitoring information, and the commander terminal 50 receiving this includes A specific mark is applied to the operator's character to indicate that it is an emergency situation. Accordingly, the commander 92 can immediately put in additional personnel so that relief measures can be taken.

In addition, when a dangerous situation such as a building collapse is detected, the commander 92 may instruct all members of an emergency evacuation order during fire suppression. When an emergency evacuation command is input through the key input unit 45, the app operation unit 46 transmits an escape command to the relay server 20, and the control unit 22 of the relay server 20 all field personnel belonging to the group. By transmitting an escape command to the terminal 40 side, and the app operation unit 46 of the field personnel terminal 40 transmits an escape command to the wearable device 60 side, the control means 66 turns the light emitting means 62 red. By emitting light with fire, the fire brigade 91 can confirm the escape command and escape immediately.

As described in detail above, according to the monitoring system for safety management of field personnel according to the present invention, since the wearable device 60 that is detachable to the user's body is used, it is easy to wear and release, and it does not affect clothes washing. It is convenient.

In addition, since it is possible to notify an escape command or the like using the light emitting means 62 located within the field of view of the field personnel, it is possible to solve the problem that the escape is delayed without recognizing the guidance voice or vibration due to the noise of the field.

In addition, in the virtual building displayed on the conductor terminal 50, site personnel are displayed on a per-floor basis according to each altitude, so that the status of on-site personnel can be clearly checked. At this time, since the altitude information is not reflected in absolute altitude, but is converted to a relative altitude based on the commander's (92) standard, it is efficient in a site situation with a high area, and even if an error occurs depending on the site situation, the error value of the same site is almost Since it is constant, the error of the relative value is automatically corrected.

In addition, when the user's monitoring information is stored in the database 23, the data processing speed is high because it is a method of serially accumulating unstructured data within a group, rather than using pre-built data in a standardized method. In other words, in the case of a standardized data storage method, the data of all personnel was built in advance, and the data of specific personnel was frequently requested and retrieved from the conductor terminal 50, so the data processing speed was inevitably slow. Data processing is accomplished by applying a method of grouping specific users based on distance from the information transmitted by each user, and then collectively transmitting the information in the group to the conductor 92 of the group, without pre-determining how to store the data. It can be done very quickly.

Preferred embodiments of the present invention described above are disclosed for the purpose of illustration, and those skilled in the art who have ordinary knowledge of the present invention will be able to make various modifications, changes and additions within the spirit and scope of the present invention. And additions should be seen as falling within the scope of the claims of the present invention.
