The radiation dose data that utility model is sent by main control module collection radiation detector, and the gps data produced in transportation is together sent to Surveillance center by wireless data transfer module, video information in the car of source is sent to Surveillance center by video monitoring module and onboard wireless data transmission module simultaneously, in Surveillance center's usage data, gps signal generates the mobile location information of radioactive source and the radiation dose data of corresponding described mobile location information, if the radiation dose in carrying shield weakens, then Surveillance center thinks that radioactive source body have left source container, trigger alarm, the accidents such as tank body are not loaded after avoiding radioactive source to use, the mobile location information of radioactive source compares with the source car GPS information passed back, if both exceed 10 meters, then radioactive sources lost is thought by Surveillance center, trigger alarm, form the Double-linkage alarm mechanism of logging radiation-resource monitoring, thus realize the automatic monitoring in logging radiation-resource transport and use procedure and warning, achieve power management and the control of each module in carrying shield, and wireless charging function, thus be convenient to long-time monitoring and field is monitored in real time.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation sketch of logging radiation-resource mobile monitoring system.
Embodiment
For clearly demonstrating the technical solution of the utility model, providing below preferred embodiment and being described with reference to the accompanying drawings.
Structural representation shown in Figure 1, whole system comprises three parts.
A part is the data acquisition of tracking and monitoring radioactive source tank body, transmission system, specifically comprise: a main control module (as PLC single-chip microcomputer), link with main control module and the radiation monitor controlled, GPS locating module, mass storage (also can, storage data are directly sent to Surveillance center to store), wireless data transfer module (as DTU data transmission module), and the main control module rechargeable battery of powering and wireless charging control module, the teleswitch of GPS locating module and wireless data transfer module, and main control module controls the dormancy of wireless data transfer module and start by set date.This part by single unit system in a container, and with logging radiation-resource tank body integrated connection, the antenna of GPS positioning system stretches out in tank body, and GPS locating module to be set up with global position system by antenna and is connected in real time; For the ease of carrying, handle set up by container.
Two parts are data acquisition and transmission systems that the video monitoring in the well logging source car of radioactive source tank body is loaded in monitoring, specifically comprise: video acquisition terminal, video information brightness and color pre-service and compression processing module, Vehicular video wireless transport module.
Three parts form Surveillance center by computer-controlled wireless data receipt modules, warning system and control software design.
Three parts set up data wireless transmission with 2G, 3G and/or 4G wireless data transmission network connect for carrier.
Its course of work is: radiation detector and GPS module are arranged on logging radiation-resource carrying shield, the radiation dose data of Real-time Collection and gps data are sent to main control module, by main control module, these data are sent to wireless data transfer module, then be sent to Surveillance center.After Surveillance center receives data, by gps data, in Geographic Information System (GIS, Geographic Information System), the display geographic position of radioactive source and the radiation data of radioactive source.Meanwhile, video information is sent it back Surveillance center by wireless data transfer module by the video monitoring module in the car of source, and shows the video information in the car of source.
The radiation dose that extracts from mass storage of main control module and GPS locator data in addition, and generate the packet of response, and by described Packet Generation to Surveillance center.
The wireless data transfer module of radiation dose and GPS locating information and the vehicle-mounted wireless data of source car video monitoring information reportedly defeated module integration have 2G, 3G or 4G radio modem, there is multiple less radio-frequency sending mode, comprise GPRS, CDMA and WCDMA wireless data transmission mode.
Data-signal, by the data-signal of network reception from radioactive source body and source car, is resolved, is recovered the video data in the radiation dose data of radioactive source, the gps data of radioactive source, the gps data of source car and source car by Surveillance center.In generalized information system, the geographic position of display radioactive source and source car, the radiation data of source car interior video and radioactive source.
When the radiation dose in carrying shield weakens, or the shift position of radioactive source and car shift position, source are more than 10 meters, then Surveillance center can send alerting signal, video in the mobile route of the radioactive source shown by generalized information system and source car, source car and radioactive source radiation dose, user can analyze warning reason, judgement is that radioactive source body have left source container, trigger alarm, or radioactive source is lost from source car, trigger alarm, thus process of taking measures in time, do not load the accidents such as tank body after avoiding radioactive source to use.
Further illustrated by above-described embodiment, supervisory system in the utility model, by the radiation dose data that main control module collection radiation detector sends, and the gps data produced in transportation is together sent to Surveillance center by wireless data transfer module, video information in the car of source is sent to Surveillance center by video monitoring module and onboard wireless data transmission module simultaneously, thus realizes the automatic monitoring in logging radiation-resource transport and use procedure and warning; Achieve power management and the control of each module in carrying shield, and wireless charging function, thus be convenient to long-time monitoring and field is monitored in real time.
