Description

The useful model belongs to the field of search devices and is intended for the indication of traces of drug-containing substances in the air. The action of the device is based on the result of air analysis for the content of vapors of narcotic substances, in particular tetrahydrocannabinol. A special control scheme allows you to measure in a semi-automatic mode with the subsequent formation of a speech message depending on the result of the analysis. The device is intended for use in field conditions.

Detection of traces of narcotic substances is carried out in the course of combating illegal drug trafficking. Today, compact devices for detecting the presence of vapors or microparticles of drug-containing substances are known, intended for use in field conditions, the action of which is based on various physical principles. The most widespread are devices that use gas chromatography/mass spectrometry sensors (GC-MS devices), sensors based on polymer conductors and metal-oxide semiconductors.

The most famous device for search use is the Zabge 5000 device of the Ztiine company

Oeiesiop (pYr:/Lmymlmu.vtiipzaeiesiop.sot/giv5/6003.rpr), which allows for the detection of vapors and traces of drugs and explosives, weighs 3.2 kg and uses GC-MS sensors. The device works at room temperature and is used by pre-trained personnel (analogue).

Also well-known is the Kerber device based on GC-MS, manufactured by the Russian company ZAO Yuzhpolymetal-Holding (pYr/Llymly.rpii.gy/dez.avr?yt-53678161-04.03).

This device has a sensitivity of 1072 g/l, the analysis time is no more than 5 seconds, and its weight is about 3 kg.

The above devices have high sensitivity and resolution, but are characterized by significant weight and cost.

The closest to the proposed useful model is the Sugapose 320 device of the American company Zepzidepi (per/Lymly. zepvidepi.sot/rgodysiv/sugapose.piti). This device is quite compact and light in weight (0.9 kg weight), since the latest versions of the device use a system of nanocomposite sensors of various types (MoseSpNir), which, in addition, allow it to be easily modified for various tasks. A liquid crystal display with backlight is used to display the measurement results, as well as to set the device.

From This device is protected by a patent belonging to the company Sugapo 5siepsev5 Ips. (Patent

USA 05 6,658,915 B2 "Ropabie zepzog", publ. 09.12.2003 prototype). According to the patent, the device includes a sensor unit with a reference resistor, a sensor unit signal mixer, a sensor unit signal amplifier, an analog-to-digital converter, a central control processor that is connected to dynamic and non-volatile memory devices, a display and an input device (keyboard). , which also controls the inlet valves and the air pump. The control system is quite complex and includes both a sequence of commands for turning on and operating the sensor unit, which may require preliminary preparation, switching commands in the field of the device to change the method of calculating the result and adapting the device to detect certain substances (training). The sequence of actions and control of the device is displayed on the display. The specified patent quite fully describes the possible design features of the device, including the use of layout methods and the type of sensors that can be used, designs and algorithms of the sensor unit, etc. Practically realized Sugapohze 320 samples have up to 5 main control switches.

The versatility of the device requires the mandatory use of a display that allows you to implement various functions of the device.

The essence of the useful model is the drug vapor indicator, which analyzes the air for the content of drug vapors and provides information about the measurement results in the form of voice messages. Drug vapor indicator, which consists of an air analysis unit, an air intake probe, a pre-concentrator and an analyzer, characterized in that it has an electrical power source with an on button, the first output of the analyzer is connected to the first input of a non-volatile memory device, the second the output of the analyzer is connected to the first input of the control unit, the third output of the analyzer is connected to the first input of the speech message generation unit, the first output of the control unit is connected to the second input of the non-volatile memory device, the second output of the control unit is connected to the second the input of the speech message generation unit, the output of the speech message generation unit is connected to the loudspeaker; the control unit has a control key, a volume control, and an LED.

A schematic representation of the indicator is shown in Fig. 1. The device consists of a unit for analyzing the air for the content of vapors of a narcotic substance 1, a permanent memory device for storing work results 2, a unit for generating speech messages 3,

the loudspeaker 4, the control unit 5, which is connected to the control key 6, the volume control 7 and the LED 8, the DC power supply unit 9 with the device power-on key 10.

The air analysis unit for the content of vapors of a narcotic substance 1 usually includes a remote probe for air intake ia, a preliminary concentrator 16 with an air pump and the actual air analyzer 1b. The analyzer and the concentrator can be made according to known standard schemes and have no features. Turning on the analysis unit takes place according to the command from the main control unit of the device, and its operation - according to the commands of the internal processor.

The main operating modes of the device are set by the control unit 5. Pressing the control key 6 allows you to turn on the measurement mode, play voice messages and switch to standby mode. The operating mode of LED 8 shows the state of operation of the analysis unit, and the volume control 7 allows you to adjust the volume of signals and calls up to their complete shutdown.

The permanent memory device allows you to document all the processes of the device, the results of measurements, their real time and other service information. The voice message generating unit C contains a sound processor with an output amplifier that generates certain, pre-programmed voice messages or a call signal to the loudspeaker 4. The power supply unit 9 with the switch 10 is standard and has no special features.

The operation of the device is shown in the cyclogram of Fig. 2. When turned on, the device after a certain time goes into standby mode for the start of measurement command (stage A). When the control key (interval B) is pressed, the analysis unit is turned on, which carries out all the necessary sequential measurements (stage B) and transmits the measurement results to unit C and at the same time the signal of the end of the measurement to control unit 5. Following this signal, the control unit switches the LED to flickering mode with low duty cycle and at the same time gives a command to the block

From to play the call signal (simulation of the call signal of a radio station or a mobile phone). The call signal has a limited duration and can also be reduced or completely turned off using the volume control, and the level of the call signal is set by control 7. After the next press of the control key on

A speech message corresponding to the results of the analysis (stage E) is provided through the loudspeaker (or the speaker of the earpiece depending on the need). Depending on the value of the received signal, the result is divided into gradations, depending on which a certain command is given to play a voice notification, for example: "Drug is missing"; "Low concentration"; "Average concentration"; "High concentration" or any other notification options.

Such a voice message will be repeated until the next press of the control key (interval Ж), after which the device will again switch to the working mode of waiting for the command to start the measurement.

For operational reasons, the device (useful model) can be made in the form of a standard portable radio station, while the air intake probe is made in the form of an antenna similar to it in size and appearance, the control key is made as a transmission mode key (PTT key, Ryvp-To-Taik ). Other relevant components of the utility model can also be made as elements of the radio station: volume control with power switch, radio speaker, power-on indicator.

The use of a useful model has the following advantages: - the control of the device is maximally simplified - to start work and receive a message about the results of the analysis, you only need to press one control key; - the results of the analysis are provided in a simplified form, understandable to a non-specialist; - the constructive construction of the device allows it to be used in difficult operational conditions.
