Among them, the MPU6050 three-axis motion processing component 3 is composed of a three-axis accelerometer 4 and a three-axis gyroscope 5, and its main functions include:

(1) The accelerometer 4 is essentially an oscillating system, which is installed inside the moving carrier and can be used to measure the moving acceleration of the carrier. The working principle of the MEMS accelerometer 4 is that when the accelerometer 4 is accelerated together with an external object (the acceleration of the object is the acceleration to be measured), the mass block will move in the opposite direction under the action of inertial force. The displacement of the mass block is limited by the spring and the damper, and the external acceleration can be measured through the output voltage. Accelerometers currently on the market are divided into two types in terms of output, one is digital and the other is analog. The three-axis accelerometer 4 of the MPU6050 three-axis motion processing component 3 is a digital sensor with an I2C interface. The range of acceleration can be configured through specific commands, and the conversion result of the internal ADC can be read out.

(2) The gyroscope 5 is a sensor for testing angular velocity, and its strength lies in testing the rotational movement of the device itself. The three-axis motion processing component 3 integrates a three-axis gyroscope 5 with a full angular velocity range of ±250, ±500, ±1000 and ±2000 ゜/sec(dps), with three gyroscopes 5, each gyroscope 5 Each is responsible for detecting the rotation speed of the corresponding axis, that is, detecting the speed of rotation around each axis.

Among them, the magnetometer is used to sense the geomagnetic vector to calculate the angle between the module and the north, and use the Wheatstone bridge to detect the change of the AMR resistance to sense the external magnetic force. HMC5883 three-axis magnetometer 2 has three bridges inside. The three-dimensional magnetoresistive sensor is installed according to the three-dimensional coordinate system of the carrier. By measuring the three-dimensional magnetic induction of the magnetic field of the carrier space, the attitude information of the carrier in space can be calculated according to a certain algorithm.

The attitude meter of the elevator car top distributor is installed on the top of the car. After installation, it is necessary to calibrate the three-axis acceleration of the attitude meter, the three-axis gyroscope 5, and the HMC5883 three-axis magnetometer 2, and determine that its current position is calibrated to be placed horizontally. When the elevator shakes during operation, the maintenance personnel can open the display interface of the attitude instrument through the hand-held operator, and the elevator main controller 6 will combine the floor data of the hoistway learned by the frequency converter and the three sets of sensor data of the attitude instrument to calculate the degree of car shaking. For the specific location, the maintenance personnel can find out where the problem is based on the calculated location data, and can make timely repairs. Maintenance personnel can also draw a speed curve by observing its acceleration to understand the comfort of the elevator.

Further, when the elevator shakes during operation, the elevator car roof distributor installed on the top of the elevator car can judge the attitude of the car as leaning left, right, upward, or downward. The working principle of the attitude indicator of the elevator car top distributor is a highly rotating gyroscope. No matter how the attitude of the car changes, the axis fixation of the gyroscope 5 remains the same in space, so it can display the attitude of the car to the left and to the right. Combined with the relative height data of the floor when the frequency converter learns the shaft, the maintenance personnel only need to turn on the hand-held operator of the elevator and enter the function menu to know the specific position of the elevator when it shakes, and can know the car at X through the accelerometer that comes with the chip. , the case of Y, Z axis acceleration. With the addition of the three-axis magnetometer 2, the maintenance personnel can use the compass to know which direction the vibration occurs, and can quickly find the root cause of the problem and deal with it in time.

1. Be able to understand the operation of the elevator in real time, quickly find the root cause of the problem when there is vibration, and draw a curve through the acceleration to adjust the comfort of the elevator.

2. The circuit is simple, the peripheral components are few, and the production and debugging are convenient.

3. It is simple and easy to use. The maintenance personnel only need to open the operation interface to know the corresponding data information and real-time understanding of the elevator operation.
