According to the website of the Ministry of Science and Technology, recently, the Russian Tomsk Polytechnic University (TPU) released the latest news that the school and its industrial partner Tomsk Semiconductor Instrumentation Research Institute are developing micro-electromechanical sensors, namely MEMS smart sensor modules, for Positioning and navigation of automated controlled vehicles.
Â
It is understood that the module can determine the position and trajectory of cars, unmanned aerial vehicles and underwater unmanned aerial vehicles without using GLONASS and GPS, and can replace similar imported products and modules. More compact than imported parts. The project was supported by the “2014-2020 Russian Science and Technology Priority Development Area R&D Plan†with a support quota of 45 million rubles.
Â
The main component of the module is a microelectromechanical system (MEMS) based inertial sensor. The inertial sensor is equipped with a gyroscope, an acceleration sensor, and a magnetic sensor. Among them, the gyroscope is used to lock the angular motion of the target in space; the acceleration sensor is used to track the linear motion of the target; the magnetic sensor can react to the earth's magnetic field to help determine the direction of the light.
Â
According to reports, the same module usually consists of nine sensors: three gyroscopes, three accelerometers, three magnetometers, and the TPU researchers found a way to reduce the sensor to two, using two sensors in the module. One of the sensors integrates the functions of the gyroscope and the accelerometer, and the other is a magnetometer that is mounted on the same plane. The total area of ​​the module is controlled within a few square millimeters, and its small size allows it to be used in pedestrian navigation systems.
Â
In addition, if a wireless data transmission device is installed on the traffic navigation module, the target mobile information can also be transmitted to the control station, which is very practical for the staff of the emergency department, and the staff can take this Track the actions of firefighters in a building that burns fire.
Â
Experts in the TPU Precision Instrumentation Department pointed out that navigation systems equipped with new modules can be navigated without contact with satellites, in remote areas, in dense forests, in dense urban buildings, in deep waters where satellite navigation is not possible, or The navigation system should not be in contact with the satellite. At present, the results of intelligent modules based on MEMS sensors have won five invention patents, and samples will be available at the end of 2019.
