- portable computing terminal in industrial plants, in oil and chemical industries under the influence of aggressive environments;

- a computing device operating in conditions of strong magnetic fields (near powerful radio transmitters, in electrolysis shops, etc.).

The design of the computer ensures stable operation in conditions of such external influencing factors as salt fog (concentration of 5%), aggressive environments (hydrogen sulfide, ammonia, sulfur dioxide, nitrogen dioxide, ozone, mold fungi), atmospheric condensed precipitation (frost and dew), etc. .

The product stably functions in conditions of elevated ambient temperature + 50 ° C. It provides functioning under the influence of factors: salt fog, aggressive environments: hydrogen sulfide, ammonia, sulfur dioxide, ozone, molds, frost, dew. It provides functioning in conditions from + 50 ° С to -20 ° С, transportation + 70 ° С to -40 ° С.

Power supply 12-32 V without conversion, 220 V - charging via adapter.

Electromagnetic shielding of the housing 16 reduces the possibility of unauthorized removal of information by the non-contact method, provides resistance to external electromagnetic interference and emitted radio frequency radiation.

Protection from strong electromagnetic fields to the necessary extent is ensured by the aluminum-magnesium alloy (for example, AM208 alloy) of the housing 16. Due to this, the computer is noise-resistant when exposed to electrostatic discharges, nanosecond and microsecond pulsed interference. In the manufacture of the product, its electromagnetic shielding is performed, which reduces the likelihood of unauthorized removal of information by the non-contact method and increases the protection against nanosecond pulsed interference. Electromagnetic shielding can provide, for example, coating the housing 16 with ferrite materials, characterized by high magnetic losses, characterized by high absorption capacity, which allows them to be used in the form of thin-layer (up to 0.2 mm) coatings of FeO · Fe ₂ O ₃ or MnO · Fe ₂ O ₃ with an epoxy binder. In the interaction of the computer’s own radiation and external electromagnetic radiation of technical intelligence devices with the absorbing material of the shielding coating, the latter has absorption (dielectric and magnetic losses), scattering (due to the structural inhomogeneity of the radio absorbing material), and interference of electromagnetic waves, as a result of which it does not enter the external space no information about the operation of the computer.

The increased size, resolution and other properties of the dust-proof screen 3 (64 thousand colors) allows you to display a larger amount of information compared to other handheld computers and accelerate its reception and transmission. This provides additional benefits when using the device for navigation, working with spreadsheets and the Internet.

The functionality of the product provides the connection of an additional external industrial keyboard (not shown) with a USB interface, a keyboard with a Bluetooth interface. To communicate with other computers it is very convenient to use a docking station (not shown) using the built-in USB 2.0 Client and RJ-45 LAN ports. The presence of connectors (PCMCIA slots, USB 2.0 Host and RS232 / DB9 / COMl ports) makes it possible to connect a wide range of peripheral equipment (external drives, DAC / ADC, etc.).

The ability to deliver products with a pre-installed operating system allows you to use a huge number of applications compatible with the line of operating systems. Sealing the housing 16 allows you to protect your computer equipment from dust and water jets from any direction.

The industrial protected handheld computer has small weight and overall dimensions (fits in a person’s hand), it is compatible with Microsoft Windows XP / 7 or Linux operating systems.

The adopted design solutions for sealing provide a general degree of protection IP65 (Dust can not get into the device. Full protection against contact. Protection against water jets from any direction) according to GOST 14254-96 "Degrees of protection provided by shells (IP code)" and increase reliability PZKK.

The handheld computer maintains its working condition under external influencing factors (climatic, mechanical) that occur during operation in the open air, on wheeled, tracked vehicles, on aircraft, in aggressive environments and strong electromagnetic fields, including nanosecond pulsed interference.

Mean time between failures is 7708 hours, mean time between failures is 9925 minutes.

Thus, an effective functionally adapted handheld computer was created and the arsenal of handheld computers was expanded.

As a result of use, the possibilities of long-term work on the screen and on the keyboard in production and field conditions of low light, low temperatures (work with gloves) are expanded, while increasing the volume and quality of information on the screen, the viewing angle is expanded from 110 to 170 degrees, a compact, flattened design, low weight, all this allows you to conveniently place it on overalls. All this increases the efficiency of the computer as a whole.
