Description
Technical Field

Background
Radiation being emitted by a field sourceElectromagnetic fieldSome of the energy is far away from the field source and then no longer returns to the field source, and the energy is diffused out in the form of electromagnetic waves or particles (e.g., alpha particles, beta particles, etc.). Radiation is extremely harmful to human bodies, and when radiation pollution (such as radiation pollution caused by nuclear leakage or chemical leakage) occurs, the radiation pollution area needs to be monitored and marked in time so as to reduce the influence of the radiation pollution as much as possible.
For radiation (pollution) monitoring on land, a marker throwing device is generally arranged on a monitoring vehicle, then the monitoring vehicle is controlled to move in a radiation pollution area and throw a marker, and each monitoring point in the radiation pollution area is marked through the marker. However, when radiation pollution occurs, radiation pollution exists on land and radiation pollution exists in air to different degrees, because radiation source substances can fly in the air along with wind, and radiation "diffusion" is realized.
In order to monitor airborne radiation pollution, the applicant thought to design an airborne marker that can fly like a drone to a designated monitoring point in the airspace of the radiation polluted area and perform a measurement of the radiation intensity. However, in the air radiation monitoring process, after each air identifier finishes the collection of the radiation intensity data of the corresponding monitoring point, the data needs to be transmitted back to the set management terminal for analysis.

Therefore, the correspondence of the aerial position and the radiation intensity of each monitoring point is very important for radiation monitoring. For this purpose, the applicant has designed an aerial 3D radiation monitoring system based on aerial positioning, which is capable of measuring and returning radiation intensity data of monitoring points in the aerial region of the radiation pollution area, and making the aerial position of the monitoring points correspond to the radiation intensity thereof.

Detailed Description
The following is further detailed by the specific embodiments:
the first embodiment is as follows:
the embodiment of the invention discloses an aerial 3D radiation monitoring system based on aerial positioning.
As shown in fig. 1: an aerial 3D radiation monitoring system based on aerial positioning comprises a management terminal and a plurality of aerial identifiers.
The aerial marker comprises a marker terminal and a marker flying unit for driving the marker terminal to fly to a corresponding monitoring point in the aerial region of the radiation pollution area; the identification terminal comprises a measuring unit for acquiring radiation intensity data of a corresponding monitoring point, a positioning unit for acquiring air position data of the corresponding monitoring point and a data transmitting unit for transmitting the radiation intensity data and the air position data; the management terminal is used for controlling the identification flying unit to drive the identification terminal to fly to the corresponding monitoring point, and establishing the correlation between the air position and the radiation intensity of the air identifier according to the radiation intensity data and the air position data corresponding to each air identifier.
In this embodiment, the airspace of the radiation-polluted region refers to a region within five hundred meters above the ground of the radiation-polluted region. The aerial marker is formed by reforming the existing marker. Current marker includes the bearing portion and sets firmly the sign pole at bearing portion top, and bearing portion generally designs for the hemisphere, and aerial marker is with the sign pole replacement of current marker for current unmanned aerial vehicle, drives the flight of bearing portion promptly through unmanned aerial vehicle. And unmanned aerial vehicle is the sign flight unit of this embodiment promptly, and the bearing part is the sign terminal of this embodiment promptly. The measuring unit is an existing radiation intensity measuring instrument; the positioning unit is the positioning module that uses on the current unmanned aerial vehicle it can acquire current position data and altitude data. The management terminal is an existing background server and can control the identification flying unit to drive the identification terminal to fly and receive and process the radiation intensity data and the air position data.
In the actual monitoring process, the management terminal controls the aerial marker to fly to the position of a monitoring point of an airspace of a radiation pollution area, the measuring unit acquires radiation intensity data at the monitoring point, meanwhile, the positioning unit acquires aerial position data (the aerial position data comprises position, height and other data) at the monitoring point, then, the corresponding data are transmitted back to the management terminal through the data transmitting unit, and the management terminal can establish the correlation between the aerial position and the radiation intensity of the aerial marker. In the invention, the aerial marker is provided with the marking flying unit which can fly and move, thereby realizing aerial radiation monitoring in a radiation pollution area. Secondly, the aerial marker is provided with a measuring unit and a positioning unit, the radiation intensity data and the aerial position data of the monitoring point can be obtained at the same time, the management terminal can establish the correlation between the aerial position of the aerial marker and the radiation intensity, namely, the aerial position of the monitoring point and the radiation intensity can be corresponded, and therefore the monitoring effect of aerial radiation monitoring can be improved. In addition, the data sending unit of the aerial identifier can transmit the acquired data back to the management terminal, and the aerial radiation monitoring is favorably assisted.
In the specific implementation process, as shown in fig. 2 and 3: the aerial 3D radiation monitoring system further comprises a data transfer terminal, and a transfer flying unit capable of driving the aerial 3D radiation monitoring system to fly to a corresponding position is arranged on the data transfer terminal.
Identifying the communication mode of the terminal data sending unit as near field communication; the data transfer terminal is used for being in near field communication connection with the aerial identifiers in the near field communication area so as to receive the radiation intensity data and the aerial position data sent by the aerial identifiers and generate data packets corresponding to each aerial identifier; the data relay terminal is also used for being in remote communication connection with the management terminal and sending the data packets corresponding to the air identifiers to the management terminal. In this embodiment, the data transfer terminals each include a data conversion unit, a routing communication unit, and a network communication unit; related workers of the data conversion unit can be realized based on the existing C8051F series single-chip microcomputer; the routing communication unit is an existing Zigbee near field communication module; the network communication unit is an existing GPRS network communication module; specifically, the data transfer terminal should further include a power supply battery, a power supply control circuit, an electronic switch, a debugging interface, and other necessary components or assemblies.
In the actual monitoring process, the network reconstruction cost of the network communication module is high, and if the network communication module is additionally arranged on the aerial marker, the monitoring cost is high; the near field communication module is low in cost, but the area capable of being connected in a communication mode is small, and when the area to be monitored is large in radiation pollution, the aerial marker with a far flying position is difficult to communicate with the management terminal, so that the monitoring efficiency of radiation monitoring is low. Therefore, the near field communication mode of the data sending unit is near field communication, namely the near field communication module is arranged on the aerial identifier, compared with the network communication module, the network reconstruction cost of the aerial identifier can be better controlled, although the data transfer terminals need to be put in, the number of the data transfer terminals is far smaller than that of the aerial identifier, and therefore the monitoring cost of radiation monitoring can be reduced. Secondly, the data transfer terminal can be used as a connecting bridge between the aerial marker and the management terminal, so that each aerial marker can communicate with the management terminal and timely send radiation intensity data, and the monitoring efficiency of radiation monitoring can be improved.
In the specific implementation process, the flight position of the data transfer terminal is set in an airspace corresponding to the radiation pollution area at a fixed point, and a total communication network formed by near-field communication areas of all the data transfer terminals can cover all monitoring points in the airspace of the radiation pollution area.
In the actual monitoring process, the invention realizes 'network full coverage' in the airspace of the whole radiation pollution area by setting the data transfer terminal at a fixed point, namely, the aerial identifier put at any position in the airspace of the radiation pollution area can be communicated with the management terminal, and the radiation intensity data and the aerial position data can be timely transmitted back to the management terminal, thereby improving the monitoring efficiency of radiation monitoring.
In a specific implementation process, the near field communication connection between the air identifier and the data relay terminal is a Zigbee near field communication connection. The remote communication connection between the data transfer terminal and the management terminal is GPRS network communication connection.
The Zigbee near field communication module has the advantages of low speed, low power consumption, low cost, support of a large number of nodes on the network, support of various topologies on the network, low complexity, rapidness, reliability and safety, and is favorable for improving the data acquisition effect of the radiation monitoring data acquisition network system. The GPRS network communication module has the advantages of convenience in use, accurate and timely information transmission and off-line communication of storage and forwarding, and is beneficial to improving the data acquisition effect of the radiation monitoring data acquisition network system.
Example two:
the embodiment discloses another determination method of the relay point of the data relay terminal on the basis of the first embodiment.
In the actual monitoring process, the radiation pollution area and the airspace thereof are only a pre-estimated approximate range, namely, some areas which are not polluted by radiation exist in the airspace of the radiation pollution area, and the areas in the airspace which are not polluted by radiation do not need to be provided with an air identifier, and a data transfer terminal is not needed to be arranged to transmit data. Then, in the first embodiment, a data transfer terminal is placed at a fixed point and a "network full coverage" manner is implemented, which may cause "useless waste" of the data transfer terminal and increase the monitoring cost of radiation monitoring.
Therefore, the present embodiment discloses another determination manner of the flight position of the data relay terminal. As shown in fig. 4: in this embodiment, the flight position of the data relay terminal is also updated correspondingly according to the air position data of the air identifier, so that all the air identifiers can be connected with the corresponding data relay terminal through near field communication.
In a specific implementation process, the near field communication areas of the data relay terminals are independent from each other, and at least one aerial identifier exists in the near field communication area of each data relay terminal.
In the invention, the flight position of the data transfer terminal can be correspondingly updated along with the air position data of the air marker, namely the data transfer terminal corresponds to the position of the air marker, and compared with the modes of fixed-point delivery and network full coverage, the invention can avoid useless waste of the data transfer terminal, thereby reducing the monitoring cost of radiation monitoring. And secondly, the near field communication areas of the data transfer terminals are independent from each other, namely, the problem that the near field communication areas of the data transfer terminals are overlapped does not exist, mutual interference among the data transfer terminals can be avoided, and the identifier is favorable for establishing communication with the management terminal better.
In a specific implementation process, the aerial marker can be in near field communication connection with other aerial markers in the near field communication area; the aerial marker is also provided with a data receiving unit, and the aerial marker can correspondingly receive the radiation intensity data and the aerial position data sent by other aerial markers connected with the aerial marker in near field communication, and can send the received radiation intensity data and the aerial position data to corresponding data transfer terminals.
In the actual monitoring process, a problem that a certain aerial identifier is just outside the near field communication area of each data transfer terminal can occur, and if the data transfer terminals are separately arranged, useless waste of the data transfer terminals can be caused, so that the radiation monitoring effect is poor. Therefore, the aerial marker can be in near field communication connection with other aerial markers which are not in near field communication connection with any data transfer terminal in the near field communication area, and can receive the radiation intensity data of the aerial marker (the aerial marker which is not in near field communication with any data transfer terminal can broadcast the radiation intensity data and the aerial position data of the aerial marker through the near field communication unit), and then the received radiation intensity data and the aerial position data are sent to the corresponding data transfer terminals, so that the monitoring efficiency of radiation monitoring is improved; and, the monitoring cost is not increased due to 'useless waste' of the data relay terminal.
Example three:
the embodiment discloses a generation mode for generating a radiation monitoring network on the basis of the first embodiment.
As shown in fig. 5: in this embodiment, the management terminal is further configured to generate a corresponding radiation monitoring network according to the air position of the air identifier and the flight position of the data transfer terminal. Meanwhile, when the management terminal generates the radiation monitoring network, a main network is generated according to the flight positions of all the data transfer terminals, and then a corresponding secondary network is generated according to the data transfer terminals and all the air identifiers connected with the data transfer terminals in the near field communication mode.
According to the invention, the radiation monitoring condition in the airspace of the radiation pollution area is intuitively reflected by generating the radiation monitoring network, so that the monitoring effect on each monitoring point and the whole airspace of the radiation pollution area is better. And the mode of generating a main network according to the flight position of the data transfer terminal and generating a secondary network according to the data transfer terminal and the corresponding aerial identifier thereof ensures that the structure and the hierarchy of the whole radiation monitoring network are clearer, and is more favorable for improving the monitoring effect of the airspace in the radiation pollution area.
