Referring to FIG. 1, a human code number (HCN) in each part of a human body may be encoded by hierarchically subdividing a body part around a muscular system. This means that the human body is the highest entity, and layer 1 is the highest muscular system, the front of the body is coded as A, and the back of the body is coded as B. Layer 2 is also coded by subdividing Layer 1, and subdividing the front (A) of the body into the head and neck is A-1, the body is A-2, the arm is A-3, and the leg is A-4. Can be. Similarly, Layer 3 can subdivide Layer 2, encoding the left arm A-3-1 and the right arm A-3-2.

3 illustrates a network configuration of a sensor node and a sink node according to the present invention.

Referring to FIG. 3, the plurality of sensor nodes 320 and the sink node 310 may configure a Human Body Sensor Network (HBSN) in a star topology.

The plurality of sensor nodes 320 previously store the human code number configured as described in FIG. 1 or FIG. 2 above. Accordingly, when the sensor node 320 detects sensing data about a specific part of the human body, the sensor node 320 transmits the detected sensing data and its human code number to the sink node 310.

Then, the sink node transmits the sensing data and the human code number to the diagnostic agent through the internet network from the coordinator of the personal area network, which will be described later, and the diagnostic agent senses the body part corresponding to the human code number from the human body sensor network server. After receiving the data, the user may be remotely managed based on sensing data corresponding to a specific body part.

4 illustrates a user management system of the human body sensor network according to the present invention.

Referring to FIG. 4, the user management system of the human body sensor network according to the present invention includes a plurality of sensor nodes 411 to 414, a sink node 420, a coordinator 430 of a personal area network (PAN), It may consist of a human body network server 440 and a diagnostic agent 450.

First, a plurality of sensor nodes 411 to 414 are attached to a user's body part to detect sensing data of the body part, store a pre-assigned human code number, and refer to FIG. 3 based on the sink node 420. Compose a cluster network of a star topology.

A plurality of sensor nodes 411 to 414 attached to a user's body part are attached to a body part based on FIG. 1 or 2, and each sensor node stores a human code number accordingly.

Therefore, when the sensor nodes 411 to 414 detect the sensing data from the body part of the user, the sensor nodes 411 to 414 transmit the detected sensing data and the human code number to the sink node 420.

The sink node 420 is attached to the body part of the user and collects and transmits sensing data of the sensor node to a coordinator of a personal area network (PAN) and a personal area network. And a unique identifier address code storage unit 422 for storing the unique identifier assigned from the coordinator of in a fixed address code transmitted from the human body sensor network server.

The coordinator 430 of the personal area network manages sink nodes within its transmission frequency region and assigns the unique identifier of the sink node.

Meanwhile, the sink node 420 receives and stores a fixed address code from the human body sensor network server 440.

The fixed address code means a code indicating the location and range of the user.

In other words, a fixed address code is expressed as a range scale and an absolute address. The range scale can be expressed as a scale concept of a range concept corresponding to latitude, longitude, and altitude. The absolute address may use a scale indicating latitude, longitude, and altitude set by the designer of the system, and the present invention is not limited thereto.

A measure broken down into levels. If the code system of the scale is (1,1,1), it indicates a basic scale that is not subdivided.In this case, the scale can be omitted.If the code system of the scale is (2,2,2), latitude and longitude And an altitude subdivided into two levels.

If the code system of the address where a particular sink node is located is (1,2,1) (40,60,10), and this address is the origin of the fixed address code, the fixed address code of the sink node has a scale of (1, 2,1), and the absolute address becomes (0,0,0) so that the static address code of the sink node is determined as (1,2,1) (0,0,0).

If the latitude, longitude, and altitude of the other sink node are (90,80,40), the latitude, longitude, and altitude values (40,60,10) of the origin are subtracted from this value to (50,20,30). , Dividing this value by the scale (1,2,1) makes (50,10,30) the absolute address of the user with latitude, longitude, and altitude (90,80,40). Therefore, (1, 2, 1) (50, 10, 30) can be represented by a fixed address code of another sink node.

As such, the sink node adds the unique identifier of the sink node itself assigned from the coordinator of the personal area network to the fixed address code transmitted from the human body sensor network server, and stores the unique identifier address code.

The unique identifier includes an instruction set which is node information unique to the sink node and room information of a patient to which the sink node is attached, and when the instruction set is called Indication_SET and the user's room information is called an adder, The identifier may be expressed as {Indication_SET, sickle Addr} which is a combination of the instruction set and the sickroom information.

Referring to FIG. 5, a unique identifier assigned to a patient-attached sink node is represented by {Indication_SET, room addr}, which is a combination of an indication set, which is node information unique to the sink node, and room information of a patient to which the sink node is attached. Can be.

Here, Indication_SET may be represented by 1 byte, and an initial setting value may be 0 × ff. In addition, the ward adder, which is the ward information of the patient, may be represented by 2 bytes in consideration of the number of wards, and an initial setting value (default) may be 0 × 0000.

In the room addr, the number of seats 501 is the floor of the hospital where the patient is located, the number of seats 502 is the room number of the floor where the patient is located, and the last number of seats 503 is the floor of the room where the patient is located. Bed number (Bed_number).

For example, the room addr of Room 320, the room of the third bed patient of the 20th room located on the third floor, can be expressed as 0x3143 in hexadecimal.

Can be expressed as

On the other hand, when the sink node 420 moves from the coordinator 430 of the personal area network to the network of the star topology configured in the coordinator of the other personal area network, the new unique node is assigned to the moved sink node in the coordinator of the other personal area network. The unique identifier address code changed by receiving the identifier is stored in the unique identifier address code storage unit 422 of the sink node.

This means that when the sink node moves from the coordinator of the personal area network set to the reference distance according to the radio frequency radiation distance to the coordinator of another personal area network, the sink node transmits data through the coordinator of the other personal area network.

Then, the human body sensor network server 440 transmits the unique identifier address code of the sink node through the coordinator of another personal area network, so that the movement of the sink node can be known.

The sink node 420 may be arranged in a star topology network or a cluster tree network structure based on the coordinator of the personal area network. Of course, it can be modified depending on the characteristics of the use state or the implementation environment.

In addition, the sink node 420 may further include a transmission scheduling unit for transmitting the unique identifier address code and the sensing data of the sensor nodes 411 to 414 to the non-contention section of the coordinator 430 of the personal area network. have.

The beacon frame, which is a data transmission section of the coordinator, is composed of a contention access period (CAP) and a contention free period (CFP). In practice, sensing data to be transmitted needs to be transmitted in real time. In order to improve the transmission speed and the transmission efficiency, data may be transmitted using a non-contention period.

The coordinator 430 of the personal area network (PAN) receives data from the sink node 420 and transmits the data to the human body sensor network server or the diagnostic agent.

In detail, the coordinator 430 of the personal area network allocates a unique identifier to the sink node 420, and assigns the sink node unique unique identifier address code to which the unique identifier is assigned, to the human body sensor network server 440. And sensing data of a unique identifier address code of the sink node and sensing data of a human body part of the sensor node to the diagnostic agent 450 through an internet network.

The coordinator 430 of the personal area network sets a reference distance according to the radio frequency radiation distance so that one sink node does not overlap with the coordinators of multiple personal area networks, and there are sink nodes that cannot transmit or receive data to the coordinator. The coordinator of the personal area network can be arranged according to the usage state or implementation environment.

Meanwhile, as described above, the coordinator 430 of the personal area network receives sensing data from the sink node 420 within the radio frequency emission range of the coordinator, and assigns a unique identifier to each sink node to distinguish the sink nodes. .

In addition, since the coordinator 430 of each personal area network stores its own address address, if the coordinator 430 of the personal area network transmits the personal identifier address code of the sink node 420 together with its address address, The human body network server 440 may recognize the user's personal information and address through a database to which the personal information of the user is stored in advance.

That is, the human body network server 440 may assign a static address code to the sink node and a database 441 to which the unique identifier address code of each sink node and the personal information of the user to which the sink node is attached are mapped. Allocator 442 is included.

Meanwhile, the diagnostic agent 450 receives the unique identifier address code of the sink node 420, the body part information of the sensor nodes 411 to 414, and the information of the sensing data, and receives the unique identifier address code of the sink node. User information may be accessed by accessing the database 441 of the human body network server 440, and remote medical treatment may be performed on each body part through sensing data of a human code number attached to the body part of the user.

6 illustrates a mobility environment of a sink node according to the present invention.

Referring to FIG. 6, the coordinator A 631 of the personal area network receives the transmission data of the sink node 620 located in the area A 311 and transmits the data to the medical agent through the Internet network. This state will be referred to as an association state of a sink node.

In this situation, the sink node 620 moves from the area A (311) to the Gray Zone, for example, the corridor, to become a dis-association, and then to the area B (312). The coordinator B 632 of the personal area network is in a re-association state, which is the same process as the handoff. The diagnostic agent can then monitor the patient even while the patient of interest, ie, the patient with a particular unique identifier address code, is moving.

FIG. 7 illustrates a schematic diagram of a user management system of the human body sensor network of FIG. 6.

Referring to FIG. 7, a process of locating a patient in a mobility situation may be grasped. This means that the patient with the personal identifier {0xff, 0x3124}, which is bound to Zone A, will be separated from the Gray Zone. Then recombine in Zone B. The patient is then reassigned a unique identifier from the coordinator of the personal area network in region B to store the personal identifier of {0xff, 0x3136}.

The gray zone described above may be set as a representative gray zone in which a corridor, a lobby, etc., in a building frequently visited by a person is an area in which an urgent patient may be monitored and treated at a time when monitoring is not necessary.

Therefore, in order to constantly observe the movement of the patient in the mobility environment, the range of the gray zone is preferably limited, and preferably the radiation of the coordinator of the personal area network is not overlapped with the radio frequency radiation distance of the coordinator of the personal area network. It is desirable to arrange the coordinator of the personal area network by setting the reference distance according to the distance.

Meanwhile, when a patient having a unique identifier of {0xff, 0x3124} moves from area A to area B, the sink node attached to the patient's body transmits data to the Internet network through the coordinator of the area B's personal area network.

Then, the human body sensor network server maps the patient's unique identifier and the patient's personal information stored in the database stored in the human body sensor network server, so that the human body sensor network server can know the personal information of the patient and is transmitted to the human body sensor network server. The address of the coordinator of the area B's personal area network indicates that the patient has moved from area A to area B.

At the same time, the position information of the patient is determined through the unique identifier address code of the sink node attached to the body of the patient.

This can be performed by analyzing the data of the sink node transmitted to the diagnostic agent, as long as the diagnostic agent connects to the human body network server through the Internet network.

That is, the diagnostic agent accesses the human body network server through the Internet network to receive the personal information, the address, and the sensing data when the sink node is located in the area A, and is located in the area B when the sink node moves to the area B. In this case, telemedicine can be performed based on personal information, address, and sensing data.

8 is a flowchart illustrating a user management method of the human body sensor network of the present invention.

Referring to FIG. 8, first, a sink node attached to a body part of a user obtains a fixed address code from a human body network server through an internet network, and a sensor node attached to the body skin of the user based on the sink node. A cluster network of a star topology is configured (step 810).

That is, the sensor node stores a pre-allocated human code number, is attached to a plurality of body parts of the user, detects sensing data of the body parts, and forms a cluster network of a star topology based on the sink node.

On the other hand, a plurality of sensor nodes attached to the body part of the user stores the human code number based on FIG. 1 or 2, and is attached to the body part corresponding to the human code number.

The sink node is similarly attached to the user's body part, receives a fixed address code from the human body sensor network server, and stores the fixed address code.

Meanwhile, the sink node connected to the coordinator of the personal area network may be arranged in a star topology network or a cluster tree network structure based on the coordinator, which may be variously configured according to a user use form or embodiment. Of course.

Then, in the coordinator of the personal area network, a unique identifier is assigned to a fixed address code of each sink node of the configured star topology network, and a unique identifier address code including the unique identifier assigned to the sink node is assigned to the human body sensor network. In step 820, the server transmits to the server.

Specifically, in transmitting to the human body sensor network server, if the sink node configured in the coordinator of the personal area network moves to a network configured in the coordinator of another personal area network, the movement in the coordinator of the other personal area network is performed. The new unique identifier may be assigned to the sync node, and a unique identifier address code including the new unique identifier assigned to the sink node may be transmitted to the human body sensor network server by the coordinator of the other personal area network.

In this way, the sink node receives the sensing data from the sensor node attached to the human body part, collects the transmitted sensing data, and transmits the sensed data to the coordinator of the personal area network. Assign a unique identifier to an existing sink node.

This is a unique identifier assigned by the coordinator so that the diagnostic agent can easily determine whether the sensing data transmitted from the sink node is specifically the sensing data transmitted from the user. The coordinator assigns a unique identifier assigned to the sensor node. The unique identifier code is transmitted to the human body sensor network server.

The unique identifier of each sink node includes an instruction set, which is node information unique to the sink node, and room information of a patient to which the sink node is attached. The indication set is referred to as Indication_SET, and the room information of the user is displayed. In case of Addr, the unique identifier of each sink node may be represented by {Indication_SET, sickle addr} which is a combination of the instruction set and the sickroom information.

Then, the diagnostic agent can easily identify the user's personal information and address, that is, the user's name, disease name, disease history, address, etc., simply by accessing the human body sensor network server.

In operation 830, the human body sensor network server configures a database in which the unique identifier address code of the sink node and the personal information of the user to which the sink node is attached are mapped.

That is, since the human body sensor network server constructs a database in which unique identifier address codes of each sink node and personal information of the user to which the sink node is attached are mapped, the diagnostic agent can know user information about the unique identifier address code. In addition, the remote medical treatment may be performed on each part of the body through the sensing data of the human code number attached to the part of the user.

Then, when sensing data is transmitted from the sensor node configured with the cluster network to the sink node, the sink node transmits the unique identifier address code of the sink node and the sensing data of the sensor node to the coordinator of the personal area network ( 840 courses).

The sink node receives the human code number and sensing data of the sensor node from a sensor node configured with a cluster network, collects the received human code number and corresponding sensing data, and combines the collected data with a coordinator of a personal area network. Send to.

The sink node may configure transmission scheduling to transmit a unique identifier address code including a unique identifier of the sink node and sensing data of a sensor node in a non-contention section of the coordinator of the personal area network.

The beacon frame, which is a data transmission section of the coordinator, is composed of a contention access period (CAP) and a contention free period (CFP). In practice, sensing data to be transmitted needs to be transmitted in real time. In order to improve transmission speed and transmission efficiency, data may be transmitted using a non-contention section.

Finally, the coordinator transmits the unique identifier address code of the received sink node and the sensing data of the sensor node to a diagnostic agent through the internet network (S850).

More specifically, the process of transmitting to the diagnostic agent through the Internet network, the diagnostic agent obtains the personal information of the user to which the sink node corresponding to the unique identifier address code is attached from a database stored in the human body network server. And managing sensing data of the user according to the acquired personal information of the user.

As such, by transmitting the unique identifier address code of the sink node received from the coordinator and the sensing data of the sensor node to the diagnostic agent, the diagnostic agent sends the unique identifier address code of the sink node, the body part information of the sensor node, and the information of the sensing data. Receive the user information by accessing the unique identifier address code of the sink node to the database of the human body sensor network server, and remotely to each part of the body through sensing data of the human code number attached to the user's body part. You will be able to perform your care.
