EM-I22K Assists Rivers And Lakes Surveying
In order to ﬁnd out the basic situation of my country's rivers and lakes, and grasp the current situation of water resources development, utilization and protection, the water conservancy census team need to collect data on the area, depth and height of rivers and lakes. Facing the ever-expanding measurement scope, the census team chose an unmanned surveying and mapping vessel that integrates a variety of data acquisition devices to replace manual boating to the center of the lake for detection. As an electronic device that assists
surveyors to view and record data on the shore, in addition to being in a humid, hot and dusty ﬁeld environment for a long time, it also faces the risk of being dropped into the water. These all place a high standard on the robustness of the device.
The I22K rugged tablet is an ideal tool to help surveyors work eﬃciently. It combines high speed, versatility and long battery life, while its robust design is also made for harsh environments. I22K is designed to be MIL-STD 810G and IP65-rated, the durable construction with reinforced chassis can handle bumps on the road, drops on the ground, and
the intrusion of dust and water.
The ruggedness of the I22K tablet from the inside out allows surveyors to use it in any weather condition, combined with its 12.2-inch capacitive touchscreen that is still clearly visible in outdoor environments for easy viewing and manipulation of maps and charts. Thanks to the hot-swappable battery, the surveyor can easily replace the backup battery without shutting down the device application, allowing work and data collection to continue seamlessly.
Traditional river mapping has relied on manual surveys in shallow areas using RTK equipment, or in kayaks and boats to the middle of the Lakes. Launching was dangerous for surveyors, and in turbulent waters, kayaks and boats were diﬃcult to secure, resulting in ineﬃciencies that hampered the rapid progress of the project. To this end, the census team chose to use the unmanned ship integrated survey system to replace the traditional manual measurement. The surveyors only need to dispatch the unmanned surveying ship on the shore and read the data returned by it to complete the surveying work. The humid air conditions on the shore and the unbearable heat from the midday sun, as well as the variable weather outdoors, threaten the electronic equipment used to assist surveyors in reading and recording data. Most of the ordinary mobile electronic devices have not received special reinforcement treatment, and their durability and stability are diﬃcult to adapt to the harsh on-site environment. Therefore, the frequent failures caused the on-site operation to be unable to proceed smoothly, and the project schedule was forced to extend. In addition, due to the long-term exposure to the outdoors, a sunlight-readable display, a small size that is easy to carry, and a suﬃciently powerful battery have become necessary conditions to measure whether a device meets the needs of users.
With these requirements in mind, the water census team set its sights on the market for rugged data-collection tablets, which can operate all day in wet conditions.
While looking for the most reliable rugged tablet, the water conservancy census team found the EM-I22K. The I22K is a fully portable data acquisition tablet with an IP65 rating and ruggedness tested according to MIL-STD-810G US military standard to withstand dust, water, accidental drops and an operating temperature of up to 60 degrees Celsius (140 degrees Fahrenheit), its excellent extreme environmental resilience meets the expectations of the census team.
In the integrated survey operation of the unmanned ship, the unmanned ship equipped with GNSS navigation and various data collection equipment needs to rely on the surveyor to use RTK equipment to guide the remote route on the shore to complete the survey operation. The emergence of the I22K tablet solves the problem that surveyors cannot intuitively obtain the travelling situation of the unmanned ship and the detection data. EM-I22K tablet connected to an RTK device through the RS485 network port, and use its vivid display screen to provide image feedback of the information and data returned by the unmanned ship in the ﬁrst time, which is convenient for surveyors to adjust task instructions and analysis data on-site.
The 12.2-inch capacitive touch screen of the I22K tablet has sensors that automatically detect environmental changes, providing an eﬀective guarantee for a clear display in bright sunlight. Even in the face of high noon light, inspectors can quickly and easily perform measurement tasks with detailed real-time analysis on their screens. There is a potential fall crisis on the slippery riverbank, which is undoubtedly a severe test for ordinary equipment, but it is not a problem for I22K. Its reliability saves unnecessary worry time for surveyors.
While sturdy and durable, the I22K Tablet is also very portable. Its lightweight body that can be held for a long time without any burden provides strong mobility for outdoor surveying and mapping workers.
As a data logger and ﬁeld computer to help surveyors work eﬃciently, the I22K Portable Rugged Tablet has powerful processing performance, as well as a large storage capacity of 128 GB and 4 GB of DDR3 RAM, always providing surveyors with a seamless Fieldwork experience. The WINDOWS 10 system I22K runs is perfectly compatible with surveying and mapping software, which facilitates detailed real-time analysis of data for staﬀ. Its rich interfaces that are stably connected to MTK equipment bring real-time visualization of the measured water depth data, allowing surveyors to quickly perform all routine surveying tasks, plan routes for unmanned surveying vessels, and keep detailed data records.
Not only is the I22K powerful enough to allow surveyors to work reliably, eﬃciently and independently, but it also has reliable technology to successfully perform tasks in the harsh environment of the ﬁeld. It is completely impervious to dust and water through a specially reinforced body, and can withstand extreme temperatures, constant strong vibrations, and
challenging outdoor environments. Its screen made of ultra-hardened glass is wear-resistant and can withstand the huge impact of falling, and the touch area and numeric keypad are large enough to make data display and input easy. In addition to the practical large display, the long-lasting battery life is also the guarantee that the I22K tablet allows surveyors to carry out their survey work faster and more eﬃciently. Its hot-swappable design eliminates the inconvenience of outdoor charging, allowing work and data collection to proceed seamlessly.
