In the modern military field, with the development of information warfare, all kinds of defence operations on the performance of electronic equipment requirements become more and more stringent. tablet rugged pc, is an important part of the field of defence, with unique performance and functionality, for the military mission to provide reliable technical support. In this paper, we will analyse the technical mysteries of this field from the perspective of equipment requirements, differences with ordinary tablets and protection levels.
First, the special needs of special scenes
tablet rugged pc, its design logic, from the defence operations and industrial scenarios in the harsh physical environment and complex task requirements. Stability, reliability and security are the core design goals.
Challenges in extreme environments: from high temperature to cold, from humidity to lack of oxygen, tablet rugged pc devices need to maintain stable performance in a wide range of temperatures; at the same time, special scenarios of severe vibration (such as vehicle bumps), accidental falls (heights of up to a few metres), as well as electromagnetic interference (such as communications equipment in dense areas) and so on, are put forward to the electronic equipment of the ‘zero-failure’ hard requirements.
Functional adaptations: a screen that supports glove touch, visibility under bright light, modular interfaces compatible with military communication protocols, and high-capacity batteries adapted to long-time operations in the field are all deeply customised to meet specific mission scenarios.
Second, tablet rugged pc and the essential differences between consumer products
(I) Hardware level
tablet rugged pc adopts the concept of ‘reinforced design’: the shell mostly uses magnesium-aluminium alloy or composite fibre material, the internal components are fixed through the gluing process, and the circuit board adopts a thick copper layer design to enhance the anti-vibration ability. In contrast, the pursuit of consumer products thin and light beautiful, often using plastic or aluminium alloy shell, the internal structure of the precision but weak impact resistance.
(ii) Expandability
tablet rugged pc is usually equipped with standardised expansion interfaces (such as military aviation plug interface), built-in GPS, Beidou and other positioning modules. Consumer-grade products support Bluetooth, Wi-Fi and other common protocols, but the lack of professional equipment for the depth of compatibility.
(C) environmental adaptability
Consumer-grade products operating temperature in 0 ℃ -35 ℃, low temperature will lead to a sudden drop in battery life, high temperature may trigger automatic shutdown protection. The tablet rugged pc operating temperature range of up to -20 ℃ to 60 ℃, through the strict high and low temperature test.
Third, the level of protection:
The core indicator for judging tablet rugged pc is the protection level certification, which mainly includes two parts:
1.IP protection level
This is the international standard for dustproof and waterproof, composed of ‘IP’ + two digits. Taking common IP65 as an example, the first number 6 is the dustproof level of the tablet, the higher the number, the stronger the protection ability, level 6 means that it completely prevents the intrusion of foreign objects and dust; the second number 5 is the waterproof level of the tablet, the higher the number, the stronger the protection ability, level 5 can prevent the entry of water from any angle of the jet.
2.MIL-STD-810G
Equipment that passes this certification is equivalent to obtaining a ‘licence to live’ in extreme environments. The test covers temperature, humidity, vibration, shock and other more than 20 tests, the equipment is extremely demanding.
Conclusion
True technological breakthroughs are often the result of conquering ‘extreme conditions’. tablet rugged pc meets the special needs of modern defence operations for electronic equipment with its unique performance and functionality.
