The tablet rugged pc's ‘triple-proof’ capability is not just a boast, but has been subjected to a series of harsh tests that are almost ‘sick’! Today we will reveal the internal process!
Drop Test
I don't know if you've ever experienced the heartbreaking moment when a mobile phone accidentally falls and the screen and back cover shatters into cobwebs, but the tablet rugged pc's ‘drop-resistant ability’ is completely free of such worries.
According to the national standard, the testers will place it on a professional drop test machine, from a height of 76cm (equivalent to the height of an adult's waist) without the initial speed of free fall.
Not only to fall front, back, but also accurate impact 4 corners 6 sides, a total of 10 times.
Every time it falls, the engineer will immediately check: is the screen broken? Is the shell deformed? Is the internal function normal? 10 consecutive times are no problem before passing.
Dustproof test
Deserts, mines, construction sites ...... dust is the ‘invisible killer’ of electronic equipment. The tablet rugged pc's dustproof level can reach IP6X (the highest dustproof level), how to test it?
Firstly, inject a large amount of ultra-fine talcum powder (particle diameter less than 50 microns, finer than flour!) into the sealed cabin. Then, by shaking or blowing, let tablet rugged pc experience 2 hours.
At the end of the day, the machine is dismantled and inspected: is there any dust intrusion into the internal circuit boards? Are the button gaps blocked? Is the interface still sensitive?
Waterproof Test
Waterproof performance is the core design of tablet rugged pc. Taking IP65 waterproof rating as an example, testers will directly use a high-pressure water gun (water spray volume of 12.5 litres/minute, nozzle diameter of 6.3mm, test distance of 2.5~3m) to spray the flat panel with 360 degrees without a dead angle, and each surface lasts at least 3 minutes.
Before the test, engineers will also check and record the appearance and function/performance testing; during the test, real-time monitoring of environmental data; after the test, the machine will be disassembled again to confirm: Is there any water seeping into the screen? Are the microphone and speaker malfunctioning due to water ingress? Can the charging port be used normally?
The role of IP protection level test
And fall, and soak in water, and eat dust, these tests in the end for what? In fact, the IP protection level is like a physical examination of the device, so that users can use it with peace of mind.
User side: IP protection level is an internationally recognised protection standard, and the test standard is unified, so you can directly know how bad the equipment can be used in the environment, to avoid the gap between the ‘seller's show’ and the ‘buyer's show’.
Manufacturers: By simulating extreme environments, we can expose potential defects of the equipment in advance, and adjust the production line in time to optimise the quality of the products if there are any problems.
tablet rugged pc: technology and protection analysis
In the modern military field, with the development of information warfare, all kinds of defence operations on the performance of electronic equipment requirements are becoming more and more stringent. tablet rugged pc, is an important part of the defence field, has a unique performance and functionality, for the military mission to provide reliable technical support. In this paper, we will analyse the technical mystery of this field from the perspective of equipment requirements, differences with ordinary tablets and protection level.
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 materials, and the internal components are potted through the glue.
