Abstract

Disclosed is a TLD wireless terminal, a TLD management system, and a method for managing the TLD. A TLD wireless terminal adhered to a TLD and communicating with a plurality of repeaters including a first repeater and a second repeater located in a radiation controlled area may include a repeater determining unit configured to selectively determine the first repeater or the second repeater as a repeater for performing communication, and a first communication unit configured to transmit a packet including unique identification information of the wireless terminal to the first repeater.

Claims

1. A thermoluminescence dosimeter (TLD) wireless terminal adhered to a TLD and communicating with a plurality of repeaters including a first repeater and a second repeater located in a radiation controlled area, the TLD wireless terminal comprising:

a repeater determining unit configured to selectively determine the first repeater or the second repeater as a repeater for performing communication;

a first communication unit configured to transmit a packet including unique identification information of the wireless terminal to the first repeater; and

a gyro sensor configured to detect a motion of the TLD,

wherein the first communication unit receives time information and a predetermined packet period value according to a time from the first repeater, and transmits the packet with the predetermined packet period value based on the time information,

wherein the first communication unit transmits the packet in a predetermined first period when the motion of the TLD is detected,

wherein the first communication unit transmits the packet in a predetermined second period when the motion of the TLD is not detected, and

wherein the predetermined first period is shorter than the predetermined second period.

2. The TLD wireless terminal of claim 1, wherein

the repeater determining unit determines the second repeater as the repeater for performing communication, and the first communication unit transmits the packet to the second repeater when signal strength of the second repeater is greater than signal strength of the first repeater.

3. The TLD wireless terminal of claim 1, further comprising

a battery configured to supply power to the TLD wireless terminal.

4. The TLD wireless terminal of claim 1, further comprising

a switch configured to be pressed in an emergency situation,

wherein the first communication unit transmits the packet including emergency information to the first repeater when the switch is pressed.

5. A thermoluminescence dosimeter (TLD) management system comprising:

a TLD wireless terminal configured to adhere to the TLD and transmit a first packet including first unique identification information;

a repeater configured to receive the first packet and transmit a second packet including the first unique identification information and second unique identification information;

a server configured to receive the second packet and acquire location information of the TLD wireless terminal; and

a cabinet configured to store the TLD, check out the TLD, and return the TLD,

wherein the first unique identification information is unique identification information of the TLD wireless terminal, and the second unique identification information is unique identification information of the repeater, and

wherein the cabinet turns on power of the TLD wireless terminal when the TLD is checked out, and the cabinet turns off power of the TLD wireless terminal when the TLD is returned.

6. The TLD management system of claim 5, wherein

the server includes a check-out and return information storage unit configured to store check-out information and return information of the TLD.

7. The TLD management system of claim 5, wherein

the server includes:

a database configured to store location information of the repeater; and

a location information detector configured to inquire of the location information of the repeater from the database based on the second unique identification information, and to determine the location information of the repeater as the location information of the TLD wireless terminal.

8. The TLD management system of claim 7, wherein

the server further includes a location information storage unit configured to store the location information of the TLD wireless terminal and time information of when the location information of the TLD wireless terminal is acquired.

9. The TLD management system of claim 7, wherein

the server further includes

a warning alert unit configured to generate an alarm for notifying carry-out of the TLD,

wherein the warning alert unit generates the alarm when the location information detector determines that the repeater is located at a front gate from the location information.

10. A method for managing a thermoluminescence dosimeter (TLD), the method comprising:

transmitting, by a TLD wireless terminal adhered to the TLD, a first packet including first unique identification information of the TLD wireless terminal;

receiving, by a repeater, the first packet and transmitting a second packet including the first unique identification information and second unique identification information of the repeater;

receiving, by a server, the second packet and acquiring location information of the TLD wireless terminal;

storing, by the server, the location information of the TLD wireless terminal and time information of when the location information of the TLD wireless terminal is acquired;

determining, by a cabinet, that the TLD is checked out from the cabinet;

determining, by the cabinet, that the TLD is returned to the cabinet; and

storing, by the server, check-out information and return information of the TLD.

11. The method of claim 10, further comprising:

inquiring, by the server, of the position of the TLD;

checking, by the server, whether the TLD is returned based on the return information of the TLD; and

determining, by the server, the location of the TLD based on the location information and the time information of the TLD wireless terminal when the TLD is not returned.
