Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radioisotope tracking system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for monitoring the status of a radioactive isotope tracking apparatus (hereinafter referred to as a 'radiation source tracking apparatus' By tracking the movement and position of the moving source by using the acceleration sensor and gyro sensor, it compensates the disadvantages of the GPS position locating limit and unnecessary power consumption in the indoor and radiowave electronic environment of the source tracking device, And more particularly, to a system and method for monitoring the status of a radioactive isotope tracking device and a method for managing battery consumption, which simultaneously provide data of movement on a time basis and allow the tracking device to perform optimal power management on its own.

Radiation sources and radiological equipment in which radioactive materials are used are seriously threatened to the safety of the public if they are lost by carelessness by the administrator during transportation and transportation, or by persons who do not have knowledge of radiation sources and radiation devices. In addition, since the public damage caused by various accidents that may occur when transporting nuclear fuel rods or radioactive waste of a nuclear power plant is expected to be enormous, measures for radiation safety management such as checking the information such as usage and transportation status in real- need.

Therefore, radioactive materials related companies and related organizations confirm the actual use of radioactive sources dispersed throughout the country through real-time geographic information system (GIS) and manage the movement route and radiation dose to strengthen the level of radiation source security management, And a remote monitoring system of the radiation source for preventing loss or loss of the radiation source and providing position information for early detection in the event of an accident.

This remote surveillance system is a surveillance system that can monitor and control the source of radiation using WCDMA, GM radiation dosimeter and GPS function in the tracking device attached to the radiation source for remote monitoring of the moving radiation source. Accordingly, the tracking device transmits the position and state of the radiation source periodically moved to the control server. When the control server disconnects the periodic data transmission from the tracking device or if communication is not established, it determines that the state of the tracking device is not normal, The user can proceed to the next management step through a warning or the like.

In this case, since the use status of the radiation source moved from the control server can be monitored, it is possible to prevent the radiation source from being lost or stolen, as well as to prevent the occurrence of radiation emergency accidents and to enable quick response thereto have.

The location tracking function of the tracking device adopts a positioning using a GPS satellite signal or a cell positioning method using a base station. This has resulted in very high accuracy in positioning compared to existing position trackers. However, there is a problem that the position of the GPS positioning in the interior or underground of the building, the electric environment of the radio wave, and the industrial environment where the communication infrastructure is poor is weak. In addition, the radiation material enters the place where the radiation is shielded by the law of relativity.

In this case, the tracking device is disconnected from the mobile communication network. Nevertheless, the communication module of the tracking device consumes more power than usual to find the communication network for data transmission. In addition, there may be no long-term positional change due to reasons such as being in operation or being outside but not moving, for reasons such as storage. At this time, however, the tracking device continuously transmits the position information of the radiation source to the server. This means that the unchanging location information is continuously transmitted to the control server, which consumes power due to the redundant data transmission operation. These problems are a factor that hinders the essential role of the tracking device to transmit the location of the radiation source to the control server accurately for a long time in case of an accident. There is a need for an optimal power management technique that allows the tracking device to accurately track the position for longer periods of time under any circumstances.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

FIG. 1 is a block diagram showing the configuration of a state monitoring and battery consumption management system of a radioisotope tracking apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the entire system of the present invention includes a radioisotope tracking apparatus (hereinafter referred to as a " radioisotope tracking apparatus ") for detecting movement information for tracking a position of a moving radiation source attached to a radioisotope A tracking device 100, a tracking device 100, a tracking device 100, a tracking device 100, a tracking device 100, a tracking device 100, (Tracking device S / W) stored in the tracking device 100 to control the tracking device 100, analyze the motion information of the radiation source transmitted from the tracking devices in the whole country, and display the information to the manager, And a control server 200 that enables the control server 200 to perform the control.

As shown in FIG. 2, the tracking apparatus 100 includes a microprocessor 101 for collecting data of a radiation source for a predetermined repetition cycle time based on stored system operation settings, a WCDMA A WCDMA modem 102 for receiving position information of a radiation source received from the GPS network and transmitting movement information of the radiation source to the control server 200 together with position information of the moved radiation source, A GPS engine 103 for receiving the position information and transmitting the received position information to the WCDMA modem 102, a motion sensor 103 for detecting motion information of the radiation source including movement, direction, and acceleration of the radiation source using the gyro sensor and the acceleration sensor, (106), and a battery unit (105) composed of a built-in or rechargeable battery, to the system, A power management unit 104 for changing the data transfer cycle and switching to a dormant mode for reducing an attempt to communicate with the control server when the motion detected by the motion detector 106 is smaller than a predefined motion level, And a display unit 108 for displaying tracking device status information including communication, power supply, setting values, etc. of the tracking device, dose values detected in the vicinity of the radiation source, and error information of the device .

At this time, the microprocessor 101 stores tracking device software (S / W) for system operation setting, and performs operation and control of the system through the S / W. That is, a command such as positioning of the GPS engine 103, the WCDMA modem 102, measurement of the ambient dose of the GM detector 107, flashing of the LED display unit 108, And controls power management unit 104 on / off.

On the other hand, even if the control server 200 is unable to communicate with the base station during operation or movement in the field, and in case of an accident, positioning of the moved radiation source is difficult, Direction and acceleration of the radiation source received from the tracking device 100 based on the GPS coordinates of the source and the movement direction of the source in the indoor space while enhancing the effectiveness of the final GPS data.

The operation of the state monitoring and battery consumption management system of the radioisotope tracking apparatus according to the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in FIG. 1 or FIG. 2 denote the same members performing the same function.

3 is a flowchart illustrating a state monitoring and battery consumption management method of a radioisotope tracking apparatus according to an embodiment of the present invention.

Referring to FIG. 3, when the tracking device 100 is turned on, the microprocessor 101 collects the radiation source data for a predetermined repetition cycle time (S20). At this time, the data of the collected radiation source includes position information of the radiation source received through the WCDMA network or the GPS network, and the movement direction, direction, and acceleration of the radiation source sensed by the motion sensing unit 106 including the gyro sensor and the acceleration sensor Motion information of the included radiation source, and a radiation dose around the radiation source detected by the GM detector 107. [

In operation S30, it is determined whether or not the radiation source is moving based on movement, direction, and acceleration of the radiation source detected through the gyro sensor and the acceleration sensor among the collected data of the radiation source.

If a predetermined period of time (about 30 minutes) has elapsed in a state where the movement of the radiation source is not sensed (S40), the data transmission cycle is extended through the WCDMA modem 102 and communication attempts with the control server are reduced The switching to the sleep mode of the tracking device 100 is transmitted to the control server 200 to inform the control server 200 (S50). On the other hand, the control server 200, which periodically monitors the state of the moving radiation source, notifies the tracking device 100 of the fact that when the switching from the tracking device 100 to the sleep mode is received, The device 100 is recognized as a normal state.

The tracking device 100 then turns off the power of the communication module required for communication with the control server 200 while maintaining the function of the microprocessor 101 through the power management unit 104 at step S60.

When a predetermined time (about 30 minutes) has elapsed (S70), the power of the communication module required for communication with the control server 200 is turned on The data of the collected radiation source is transmitted to the control server 200 through the WCDMA modem 102 and then the power of the communication module is turned off in step S80. This is repeated until the movement of the collected radiation source is confirmed.

As described above, by maximizing the driveable time of the tracking device through the sleep mode of the tracking device 100, it is possible to increase the sustainability of the main role of the tracking device, thereby improving the tracking of the position even if the battery of the tracking device is not fully buffered It can be done for a long time so that the accident can be processed quickly.

On the other hand, if movement of the radiation source is detected based on movement, direction and acceleration of the radiation source including the case of the sleep mode (S30), the power of the communication module necessary for communication with the control server 200 is turned on The switching to the active mode of the tracking device 100 is transmitted to the control server 200 via the WCDMA modem 102 to inform the control server 200 (S90). At this time, if the tracking device 100 is not in the sleep mode, the process of turning on the power of the communication module is omitted because the power of the communication module is already on.

Then, the tracking device 100 transmits the data information collected from the radiation source to the control server 200 through the WCDMA modem 102 at a preset period (S100). This series of operations is repeatedly performed until the power of the tracking device 100 is turned off (S110).

At this time, the data information transmitted to the control server 200 includes position information of the radiation source received through the WCDMA network or the GPS network, and movement of the radiation source sensed through the motion sensing unit 106 including the gyro sensor and the acceleration sensor Direction, and acceleration, and a radiation dose around the radiation source detected by the GM detection unit 107. [0050] FIG.

Therefore, the control server 200 can determine the effectiveness of the final GPS data based on the movement information of the source, including the direction, direction, and acceleration of the source of radiation received from the tracking device 100 based on the GPS coordinates of the ultimate positioning of the moving source And the direction of movement in the room is inferred. This makes it possible to increase the accuracy of the actual positional locating even if it is difficult to communicate with the GPS satellite or the base station in case of an operation in case of an accident or in case of an accident in the field, and thus the positioning of the moved radiation source is difficult.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
