Detailed summary of the IMU about the analog output inertial measurement unit!

You may feel a bit unfamiliar with the term analog output inertial measurement unit. After all, we rarely come into contact with such devices in our daily lives. Here is a summary of some relevant information about inertial measurement unit devices. Friends who are interested in this can learn more about it, so let’s take a look at it together!

Preliminary introduction to the analog output inertial measurement unit

What is an inertial measurement unit

An inertial measurement unit is a tool used to measure the triaxial attitude angle. A single inertial sensor includes an accelerator and a uniaxial gyroscope device. This measurement method can accurately and quickly calculate the speed signal, running attitude, etc. of an object. It is usually applied to precision displacement estimation equipment such as vehicles, airplanes, spacecraft, etc., and has a very important value!

What is an inertial sensor?

The inertial sensor, also known as IMU, is the main component of the analog output inertial measurement unit and is also an important trend in future development. It is defined as a device that can accurately measure 3D motion and multi-angle motion without reference to peripheral components. The function is very powerful. This sensor can obtain the latest direction of motion and driving speed of the object through superposition calculation of speed, position, and other information, and correct the course and Fast and slow to ensure that the equipment does not deviate from the route and operates on the correct trajectory.

Advantages of inertial measurement units

Compared with other devices, this inertial measurement unit has more advanced technology and more comprehensive information. It has the functions of autonomous operation, automatic concealment, real-time transmission of data information, etc., and can also completely ignore the influence of other factors. In different environments such as water, sky, underground, etc., it can achieve normal operation, and the strength is very strong!

Application value of analog output inertial measurement unit

What are the application ranges

The analog output inertial measurement unit, IMU inertial sensor is widely used in motion control equipment, such as automobiles and robots, which are more common in life, and advanced equipment such as more precise missile devices, spacecraft, and aircraft, etc., and mainly play a navigation role.

Effects applied to actual equipment

With the rapid development of technology, more and more new devices have appeared. For example, autonomous vehicles do not need to be controlled by personnel at all. As long as the destination is set in advance, the vehicle will follow the designated route map to ensure that there will be no speeding or route deviations. As for robots, many forward-thinking places now use machinery and equipment to replace labor and operate gradually according to set procedures. In particular, some large shopping malls use robots as guides. It can help customers arrive at the scene accurately and quickly. Another example is a high-precision weapon such as a missile. It is extremely damaging. Once launched, it will cause extensive damage, so the accuracy of navigation of this kind of device is extremely high! The existence of analog output inertial measurement unit devices ensures that the running trajectories of these devices do not deviate, and their application value is extremely high!

Introduction to the installation location of the analog output inertial measurement unit

Regarding the installation location of the inertial measurement unit, take a vehicle close to life as an example. Autonomous driving is a new scientific and technological field, and it is also a project that major enterprises focus on researching. The following is an introduction to the installation method of the inertial measurement unit, as follows:

Because the inertial measurement unit is mainly used to measure the triaxial attitude angle, there is a certain installation angle between its coordinate system and the coordinate system of the vehicle itself. This must be calculated through careful judgment. Generally, the angle marking method of the inertial measurement unit is measured through navigation satellite systems, inertial measurement units, speed, etc., and then estimated by estimation. This method is more traditional, and the calculation method is also It’s too complicated, so many researchers currently infer from the speed at which the vehicle is traveling in a straight line. Although the noise will be higher, it is more efficient.

The measurement method of the simulation output inertial measurement unit is to collect the data of each stage during the vehicle’s driving time, calculate the parameters through navigation positioning and speed change, and then correct it in real-time according to the obtained information deviation degree to reduce the influence of the vehicle during the driving process, and then accelerate the test again after obtaining accurate data, and repeatedly correct the test until the error value is reduced to the minimum, and the final statistics Determine the installation angle of the inertial measurement unit and get accurate data information!

All about the analog output inertial measurement unit is introduced here. Because of the introduction of this technology, a large number of products have been qualitatively improved. I believe this inertial measurement unit will do better and better in the future, reaching a new level! The above is all of today’s content. If you are curious about this field, you can find this information in detail and feel the magical power of technology!
