TDF51IMU0 Fiber Optic Inertial Unit Dynamic Measurement Functions for Small Size and High-Precision Inertial Unit Equipment
Overview
Fiber optic inertial units have the advantages of small size, light weight, low power consumption, and high accuracy. They can be used to design pure strapdown, single axis, and dual axis modulation inertial units, meeting the needs of new unmanned platforms, water/torpedo weapons, as well as land and airborne weapon platforms for small size and high-precision inertial unit equipment. They have dynamic measurement functions for carrier angular and linear motion information.

Communication Protocol
a. RS422 serial port 1 outputs three channels of angle increment information, three channels of speed increment information, IO count information, temperature information, with a data frequency of 200Hz (raw observation values without interpolation are compensated for errors). The data protocol is shown in Appendix A, and the output data is not lost;
b. RS422 serial port 2 outputs a time synchronization signal at sampling time 1 (with a valid rising edge, representing the sampling time of the inertial sensor), RS422 differential signal, pulse width of 10 ± 2 μ s, sampling signal interval of 5ms ± 20 μ s, rising edge and falling edge level establishment time not exceeding 100ns, and sends serial port 1 data after 50 μ s of rising edge emission.
Output Data Protocol
a. Baud rate: 460800bps;
b. Output format: RS422, 1-bit start bit, 1-bit stop bit, 8-bit data bit, no checksum;
c. Data frequency: 200Hz;
d. Communication Protocol: The communication protocol is detailed in the table below;
e. All undefined bits are filled with 0 by default. When transmitting multiple bytes, the low byte comes first and the high byte comes last.
