The application of 10-inch reinforced industrial tablet computer in field survey and mapping
We are usually unfamiliar with 10-inch fanless ruggedized industrial tablet PCs and ruggedized tablet PCs. Unlike commercial tablet PCs, 10-inch fanless ruggedized industrial tablet PCs pay more attention to external environmental tolerance and more efficient and reliable computing performance , although it is difficult for us to really experience the intuitive feeling brought by the 10-inch fanless reinforced industrial tablet, but in real life, they play a huge role behind the scenes every day, and they are a must for special industries. "arms".
Field surveying and mapping. With the rapid development of the application of computers, ground measuring instruments, and digital mapping software, digital mapping has gradually replaced traditional manual measurement methods and has become the mainstream mode of surveying and mapping operations such as surveying and mapping production, water conservancy and hydropower engineering, and land management. The harsh and harsh operating environment of the exploration industry determines that the information management platform must meet four requirements: easy installation in different environments, PC-based internal SAP system and company integrated network; equipment must be durable, waterproof and vibration-resistant; complete machine It can work in a wide temperature range, and the working temperature is -20~50 degrees; the interface is rich, which can realize real-time collection of operating status and reliable data transmission. Therefore, a ruggedized tablet is the most suitable device for this application. In the process of field surveying, the reinforced tablet computer can be repaired at any time, so as to achieve "clearing every station and every day", which can effectively prevent errors, missed measurements, re-measurement, rework and other manual surveying and mapping work that cannot be done. avoided problems.
The post-test data processing is done on the indoor personal computer by the special software included in the system, and it can also be done on the field with a hand-held three-proof tablet computer. The method is to first download the data from the GPS receiver to the computer, and perform baseline vector calculation on the observation data: use quality inspection tools to determine and eliminate gross errors, delete unqualified baselines, etc. to edit the network diagram; The measurement network that forms a closed loop is calculated by free network adjustment, so as to eliminate the contradiction of the internal closure difference of the network diagram and make it a unique geometric figure; configure the coordinates of the known points, and carry out the constrained adjustment. Coordinate conversion work is completed while the conformity difference formed by point constraints is contradictory, and the local coordinates required by the user are directly provided. In addition, it also includes a variety of utility programs such as report generation, ephemeris forecast, and conversion of observation data to Rinex format, forming a data post-processing software package. Due to the portability, sturdiness, stability, safety, multi-function and other characteristics of the 10-inch fanless three-proof tablet computer, it effectively solves various problems and unsafe factors that may occur in outdoor surveying and mapping. Therefore, handheld three-proof tablet computers are widely used and promoted in field surveying and mapping activities.
