Description

This utility model relates to dosimeters-radiometers, that is, to devices used to control surfaces and objects that could potentially be contaminated with gamma, alpha and beta emitting nuclides. In particular, to mobile devices that additionally contain radiation detectors, that is, blocks measuring the number of particles crossing the area of a special detection unit per unit time.

Dosimeters-radiometers based on the Geiger-Muller counter, a very popular ionizing radiation detector (httD: //www.voutube.coni/watch? V = UZopH8xpi I w), are widely known. Such dosimeters-radiometers include, in particular, the devices described in US patent No. 4672544 G01T 1/18, 001T 1/22 dated 08/12/1983, EP No. 0881507 G01T 1/169, G01T 7/00 dated 05/28/1997. Such devices include a high voltage source, a Geiger-Muller counter and an output driver amplifier, the output signal of which is used to indicate radiation.

However, these devices do not allow for the prompt transfer of information about the detection of radioactive contamination. ''

A device is described in the utility model RU No. 109625 H04M 1/22. This device is the closest analogue to the claimed utility model. The known device is a mobile radio device with a dosimeter-radiometer, containing a measuring unit containing a radiation detector and an interface unit, and a mobile radio device, in the housing of which there is a power supply unit configured to supply voltage to all electronic components and units located in the housing a mobile radio device, a processor, the corresponding inputs and outputs of which are connected to the radio unit and to the memory unit, as well as an indication unit, the input of which is connected to the corresponding processor output, and a keyboard connected to the corresponding processor input. The composition of the known device also includes an amplifier, the input of which is connected to the output of the radiation detector, and the output through the interface unit is connected to the processor.

Unlike other known devices, the closest analogue allows for the prompt transfer of information about the detection of radioactive contamination using a radio unit.

The closest analogue (prototype) in functions resembles a mobile phone that performs only the function of transmitting data on detected radioactive contamination. Undoubtedly, the prototype can be implemented on the basis of a conventional mobile phone, but such an implementation will undoubtedly cause significant technical difficulties, because the input of information from the radiation detector into the processor of the mobile phone will require access to the processor information bus, which is not possible on all mobile phone models and is characterized by variety of protocols used in different models of mobile phones. In addition, you will need a power source for the radiation detector, amplifier and interface unit. All this greatly complicates the hardware implementation of the prototype and requires many of its options for different models of mobile phones.

The problem solved by the claimed utility model is to simplify the device by making it possible to use any mobile phone (mobile radio device) and due to the lack of a power supply as part of the measuring unit. This is achieved by entering information from the output of the radiation detector into the processor through the audio input of the audio unit (microphone input), and powering the radiation detector with energy from the audio output of the audio unit (headphone output). Since the audio input and audio output are in all models of mobile phones, it is not difficult to connect different models to mobile phones, and the mobile radio device with a dosimeter-radiometer is easier due to the lack of a power supply in the measuring unit.

The subject of this utility model is a mobile radio device with a dosimeter-radiometer, comprising a measuring unit containing a radiation detector and an interface unit, and a mobile radio device, in the housing of which there is a power supply unit configured to supply voltage to all electronic components and units located in the housing of the mobile radio device, the processor, the corresponding inputs and outputs of which are connected to the radio unit and to the memory unit, as well as an indication unit, the input of which is connected to the corresponding output of the processor, and the keyboard connected to the corresponding input of the processor — in this case, a step-up transformer, a rectifier and a pulse shaper are introduced into the measuring unit, and a step-up transformer, a rectifier, a radiation detector, a pulse shaper and an interface unit are included in series, and the mobile an audio unit is connected to the radio, connected to the processor, the audio output is connected to the input of the measuring unit, which is the input of the step-up transformer, and the input audio microphone unit connected to an output of the measuring unit, which is an output interface unit.

Private essential features of the proposed utility model are as follows.

The processor is configured with software for signaling an allowable and unacceptable dose, and the display unit is configured to output processor alarms in graphical, tabular or text form and to supply the necessary sound, light and / or vibration signals.

The processor is made with software for signaling the permissible and unacceptable radiation dose in the hourly, daily, weekly, monthly, annual interval.

The radiation detector is configured to measure alpha, beta, gamma and neutron radiation, as well as solar radiation, with the possibility of transmitting measurement results through a radio unit.

The keyboard contains additional keys for controlling the operation in the radiation dose measurement mode.

The radio block is made with the possibility of determining the location of the controlled object in space using GPS or GLO-NASS systems, and with the ability to transmit the set coordinates of the location of the controlled object in space through the radio block.

The processor is configured to apply the set coordinates of the location of the monitored object in space to a map of the area.

The processor is configured to save the date and time of each measurement in the memory unit, and to transmit the date and time of each measurement through the radio block.

The processor is configured to allow the camera to be photographed of the object being tested and its surroundings integrated into the mobile radio device and to store photos and videos in the memory unit, as well as with the ability to transfer photos and videos to the receiving side via the radio unit.

The processor is configured to fix additional text or speech comments of the user to each measurement performed in the memory unit, and to transmit additional text or speech comments of the user to each measurement through the radio block.

A step-up transformer, a rectifier, a radiation detector, a pulse shaper and an interface unit, which are part of the measuring unit, are located in a single casing.

The step-up transformer and the interface unit are connected to the audio unit via a JACK AUDIO plug.

The objective of this utility model is to create a fairly simple and convenient to use mobile radio device that provides an indication of radioactive radiation and allows for the prompt transfer of the results of radioactivity monitoring of a controlled sample or a controlled area.

The essence of the proposed technical solution is illustrated in figure 1, which presents a generalized structural diagram of the claimed utility model.

In Fig. 1, the following notation is used: 1 - power supply, 2 - audio unit, 3 - step-up transformer, 4 - interface unit, 5 - keyboard, 6 - processor, 7 - memory unit, 8 - display unit, 9 - rectifier, 10 - radiation detector, 11 - pulse shaper, 12 - radio block.

The considered mobile radio device with a dosimeter-radiometer contains a measuring unit and a mobile radio device. In the casing of the measuring unit, a step-up step-up transformer 3, a rectifier 9, a radiation detector 10, a pulse shaper 11, an interface unit 4 are arranged in series. A power supply unit 1 is arranged in the housing of the mobile radio device, configured to supply voltage to all electronic components and units located in the housing of the mobile radio device (the connections of the power supply unit 1 to other electronic components and units are not shown in FIG. 1). The mobile radio device also includes an audio unit 2, a keyboard 5, a processor 6, a memory unit 7, an indication unit 8 and a radio unit 12. The corresponding inputs and outputs of the processor 6 are connected to the radio unit 12 and to the memory unit 7. The input of the display unit 8 is connected to the corresponding output of the processor 6. The keyboard 5 is connected to the corresponding input of the processor 6. The information input and output of the audio unit 2 are connected to the corresponding output and input of the processor 6, the audio output is connected to the input of the measuring unit, which is the input of the step-up transformer 3, and the microphone input of the audio unit 2 is connected to the output of the measuring unit, which is the output of the pairing unit 4.

The radiation detector 10 can be made on the basis of a Geiger-Muller counter, a very popular ionizing radiation detector (http: //www.youtube.coni/watch? V = UZopH8xpi I w). The same detector is used in the above analogues of this utility model: US patents No. 4672544 G01T 1/18, G01T 1/22 dated 08/12/1983, EP No. 0881507 G01T 1/169, G01T 7/00 dated 05/28/1997.

The pulse shaper 11 in the simplest case may include a matching circuit (on two resistors, a zener diode and a capacitor). Somewhat different from the simplest version of the pulse shaper circuit 11 is shown in the above analogue of this utility model (US patent No. 4672544 G01T 1/18, G01T 1/22 from 08/12/1983).

Block 4 interface in the simplest case can be made in the form of a voltage divider on two resistors.

As an element providing connection and disconnection of the mobile radio device and the measuring unit, the plug ^ ASK AUDIO can be used. These plugs are widely available and available on

commercial market.

Thus, all the functional units and elements of the device in question are widely known and available on the commercial market or can be easily manufactured. Therefore, the possibility of practical implementation of the considered mobile radio device with a dosimeter-radiometer is not in doubt.

The proposed mobile radio device with a dosimeter-radiometer (figure 1) works as follows.

Before starting the control of the test sample, the mobile radio device functions as a regular mobile phone. The power supply unit 1 is turned on, and the required power is supplied to all nodes located inside the housing of the mobile radio device.

Measurement of radioactive contamination of a controlled sample begins with the user connecting the measuring unit to a mobile radio device.

With this connection, the housing contacts of the mobile radio device and the measuring unit are connected (that is, a common ground bus of the mobile radio device and the measuring unit is created). In addition, inside the casing of the measuring unit:

- the input of the step-up transformer 3 is connected to the contact of the audio output of the audio unit 2,

- the output of the pairing unit 4 is connected to the microphone input terminal of the audio unit 2.

Then, the user using the keyboard 5 generates a command on the processor 6, which starts the program for measuring the radioactive contamination of the controlled sample. This command can be given, for example, by pressing special keys (if there are any on the keyboard 5). The processor 6, after receiving a command, refers to the memory unit 7 to enter a program of work in the mode of measuring radioactive contamination of a controlled sample. After entering the program, the processor 6 includes a display unit 8, informing the user about a change in the operating mode of the mobile radio device. The type of this user information is set by the program of work in the mode of measuring radioactive contamination of the controlled sample and may be an audio, video signal on the monitor screen of display unit 8, a special vibration signal or a combination of these signals.

Then, the audio unit 2, at the command of the processor 6, generates a signal in its audio output in the form of an unmodulated signal with a given frequency and amplitude set in the program of the measurement mode of radioactive contamination of the controlled sample.

This signal is an input signal for step-up transformer 3, which is part of the measuring unit. The step-up transformer 3 increases the voltage of the input signal to the desired value, after which this signal is fed to the rectifier 9. The output signal of the rectifier 9 is the high voltage necessary to ensure the operation of the radiation detector 10. The voltage should correspond to the so-called "plateau", that is, the supply voltage range of the radiation detector 10, small fluctuations within which do not affect the measurement result.

Short pulses are formed at the output of the radiation detector 10 due to impact ionization. The pulse shaper 11 brings the short pulses arriving at it to a predetermined amplitude and duration, after which it transfers the received pulses to the interface unit 4.

The interface unit 4 brings the pulses arriving at its input to the form necessary for the audio unit 2 to enter the microphone input. Next, these pulses go to the mobile radio device — to the microphone input of the audio unit 2.

The supply voltage for the pulse shaper 11 and the interface unit 4 can, for example, be formed on a step-up transformer 3 by winding an additional winding and subsequent rectification.

In a mobile radio device, the pulsed signals from the audio unit 2 are sent to the processor 6, where they are calculated for the time interval set during programming. The results obtained are compared in the processor 6 with the maximum allowable taken from the memory unit 7. Next, the processor 6 generates and reflects on the display unit 8 an information message, such as "NORMALITY 80% TOLERANCE" or "EXCEEDING 240% TOLERANCE". The signal about the formation of such a message is transmitted for storage to the memory unit 7, accompanied by service information about the date and time of each measurement. In the General case, information messages can be displayed on the display unit 8 in graphical, tabular or text form and accompanied by the supply of the necessary sound or vibration signals.

At the same time, the processor 6 is executed with software for signaling the permissible and unacceptable dose of radiation in the hourly, daily, weekly, monthly and annual intervals.

Through the radio block 12, the result obtained, if necessary, is transmitted by the processor 6 to the interested consumer. Additionally, service information about the date and time of each measurement can be transmitted. This information is supplied to the processor 6 from the memory unit 7 for transmission through the radio unit 12.

In this case, the result can be supplemented by the location data of the object for which control was carried out. These data can be obtained by navigation devices using GPS or GLONASS systems (if the radio unit 12 of the mobile radio device includes such navigation devices). In this case, the result of the verification may, for example, be a conclusion that the permissible level of radioactive contamination is exceeded in a certain field or in a certain landfill.

If necessary, the processor 6 through the display unit 8 can affix the location of the monitored object on the map.

The composition of the mobile radio device can be integrated camera (in the drawing of figure 1 is not shown). In this case, the processor 6 can take pictures of the tested object and its surroundings, and then save the photos and videos in the memory unit 7. Depending on the program of work installed in the processor 6, photos and videos can also be transmitted to the receiving side via the radio unit 12.

At the end of the measurement, the user can transmit through the audio block 2 to the processor 6 additional text or speech comments on the measurement. These user comments, depending on the installed program of work, can be recorded in the memory unit 7 and / or transmitted to the receiving side, to the interested user, via the radio unit 12.

At the end of all measurements, the user using the keyboard 5 generates on the processor 6 a command to disable the program for measuring radioactive contamination of the controlled sample.

According to the method described above, alpha, beta, gamma and neutron radiation, as well as solar radiation, can be measured. The type of measurement performed is determined by the type of radiation detector 10 used, which, in the general case, can be removable and replaceable.

The most convenient for the consumer connection and disconnection of the mobile radio device and the measuring unit, in the casing of which there is a step-up transformer 3, a rectifier 9, a radiation detector 10, a pulse shaper 11 and an interface unit 4, are provided when using the JACK AUDIO plug for connecting and disconnecting. These plugs are commercially available.

When using the JACK AUDIO plug, its contacts are used for:

- transmitting the signal from the audio output of the audio unit 2 to the input of the step-up transformer 3;

- transmitting a signal from the output of the pairing unit 4 to the microphone input of the audio unit2;

- connection busbars (- ^ -) mobile radio and measuring unit.

Thus, thanks to the introduced nodes and connections, the problem of the utility model has been solved: a simple and easy-to-use mobile device has been created on the basis of the well-known mobile phone, which provides operational radioactivity monitoring and operational transmission of the radioactivity monitoring results of a controlled sample or a controlled area.
