Description

Technical Field [0001] The present invention relates to a tracking apparatus for preventing missing data, a radioisotope tracking apparatus, and a device for accumulating data between control servers,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a state monitoring and management system for a radioactive isotope (hereinafter referred to as a 'radiation source'), and more particularly to a radioactive isotope tracking system (hereinafter referred to as a 'tracking device' And more particularly, to an apparatus and method for accumulating data between control servers.

Radiation equipment and radioactive materials are frequently used in transportation and mobile use due to the carelessness of the manager and theft by people who do not have knowledge of radiation source and radiation equipment. 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 use and transportation conditions are necessary .

Therefore, radioactive materials companies and related organizations should confirm the actual use of radioactive sources scattered throughout the country in real time through 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 and providing location information for early detection in the event of an accident.

The remote surveillance system is a surveillance system that can control and manage the radiation source to be used while moving using WCDMA, GM radiation dosimeter and GPS function in the tracking device attached to the radiation source.

The currently commercialized radiation source tracking system transmits the position and state of the periodically moved radiation source to the control server. At this time, when the periodical data transmission is disconnected from the tracking device or the communication is not performed, the control server determines that the state of the tracking device is not normal It is possible to proceed to the next management step through a warning or the like to the manager.

In this way, it is possible to monitor the usage status of the radiation source moved from the control server, thereby preventing the radiation source from being lost or stolen, as well as to prevent the occurrence of the radiation emergency accident and also to cope with it.

However, the radiation source enters the place where the radioactivity is shielded by the related law. In this case, the connection between the tracking device attached to the radiation source and the mobile communication network is frequently blocked. Thus, the tracking device attempts to transmit data when the schedule for data transmission is the same as in the conventional case even when the connection with the mobile communication network is not smooth. If the data transmission is unsuccessful, the data to be transmitted is deleted regardless of whether the transmission is successful or not after a maximum of 3 retransmission attempts.

In the case of the transmission failure, the state data of the radiation source is omitted from the control server. If this happens, there is no way to know what the state of the radiation source was during the time the data was missing. In particular, considering that the damage caused by various accidents that may occur when transportation and transportation of radiation devices using radioactive materials are used is enormous, it is necessary to monitor more precisely the source of radiation, It is necessary to construct a new system between tracking device and control server.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It is provided to let you know. 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 illustrating an overall system for cumulative data transmission between a tracking device and a control server for data omission prevention according to an exemplary embodiment of the present invention. Referring to FIG.

 1, the overall system of the present invention detects location information and motion information for tracking the position of a radiation source moved and attached to the radiation source 300, and a dose value around the radiation source, (Hereinafter referred to as a 'tracking device' or 'a source tracking device') for accumulating and storing measured data until a communication-enabled environment is given when data transmission to the control server 200 fails, And a control server 200 for monitoring and managing a moving radiation source of the whole country on the basis of data transmitted from the tracking device 100.

As shown in FIG. 2, the tracking apparatus 100 may include information on the position of the radiation source 300 measured in the radiation source 300 for a predetermined repetition period based on the stored system operation settings, A microprocessor 101 for collecting dose values and detecting the success or failure of data transmission to the control server 200 and for receiving the positional information of the radiation source 300 received in the WCDMA network via the WCDMA antenna, A WCDMA modem 102 for transmitting the dose value around the radiation source 300 to the control server 200 together with the position information and motion information of the radiation source 300 and the position information of the radiation source 300 received from the GPS network through the GPS antenna Direction and acceleration of the radiation source 300 using a gyro sensor and an acceleration sensor, a GPS engine 103 that transmits the radiation source information to the WCDMA modem 102, A GM detection unit 107 for detecting a dose value in the vicinity of the radiation source 300 and a control unit 110 for controlling the control server 200 based on the success or failure of data transmission detected by the microprocessor 101. [ The movement classification unit 104 classifies the position information, the motion information, and the dose value of the radiation source 300 that has failed in data transmission to the transmission classifier 104; And a display unit 108 for displaying tracking device state information including communication, power, 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 for positioning the GPS engine 103, the WCDMA modem 102, a measurement of the ambient dose of the GM detector 107, a flashing of the display unit 108, 104 and the like.

Meanwhile, even if the control server 200 is in an environment where it is difficult to communicate with the base station during operation or movement in the field, or in case of an accident, and thus the data transmission of the radiation source is difficult, And when an accident situation occurs on the basis of data transmitted to the control server 200 in the future, it is determined what the radiation source 300 was during the time when the data is missing and the accident occurrence situation is inferred.

The operation of the tracking device-control server data accumulation transmission device for preventing data loss according to the present invention will now 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 data accumulation method between a tracking device and a control server for preventing data loss according to an embodiment of the present invention.

First, when the tracking device 100 is turned on, the microprocessor 101 collects data of the radiation source 300 for a predetermined repetition cycle time (S20). The data of the collected radiation source 300 may include position information of the radiation source 300 received through the WCDMA network or the GPS network and information of the radiation source 300 sensed through the motion sensing unit 106 including the gyro sensor and the acceleration sensor Motion information of the radiation source 300 including motion, direction, and acceleration, and a radiation dose around the radiation source detected by the GM detection unit 107.

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 predetermined time interval (S30). This series of operations is repeated until the power of the tracking device 100 is turned off (S40).

Meanwhile, if communication with the control server 200 is not smooth due to communication network interruption and the data transmission to the control server 200 fails (S40), data retransmission attempted at a predetermined interval is attempted (S50) . At this time, when the first retransmission fails, retransmission of the retransmission to the control server 200 is tried repeatedly up to the third time (S60). It should be noted that the above-described tertiary is for the purpose of describing it specifically in the preferred embodiment and not for the purpose of limitation.

If the retransmission of the data fails even through the repetition of the retransmission, the position information, the motion information, and the peripheral dose values of the radiation source 300 failing to transmit data to the control server 200 through the transmission classifying unit 104 are classified (S70), and accumulates and stores them in the untransmitted data DB 105b of the storage unit 105 (S80). At this time, the position information, the motion information, and the peripheral dose values of the radiation source 300, which are accumulated and stored, are classified and stored in units of time, and when they are classified during the previous time according to the cumulative data storage protocol, It is possible to store only time information without storing data and overwrite new data with no additional storage, thereby reducing the amount of data to be transmitted and the limitedness according to the limited memory.

Thereafter, when the environment surrounding the tracking device changes to a state of smooth communication with the control server 200 through the movement of the radiation source 300 or the like, the position of the radiation source 300 accumulated and stored in the storage unit 105 on a time- Motion information, and peripheral dose values to the control server 200 through the WCDMA modem 102 (S90).

 In step S100, transmission to the control server 200 is performed until transmission of data accumulated and stored in the storage unit 105 is completed.

Accordingly, the control server 200 receives the missing information on the basis of the data accumulated and transmitted at a later time from the tracking device 100, so that the reason for the information missing is not a fault of the tracking device 100, And recognizes that the tracking device 100 is in a normal state. In addition, even when an accident or the like occurs, there is no omission of data, and it is determined what the radiation source 300 was, .

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.
