Description

Technical Field

[0001] The invention belongs to the technical field of closed-loop fiber optic gyroscope control electronics, and in particular relates to a method for adaptively switching working modes of a closed-loop fiber optic gyroscope control circuit. Background Art

[0002] As a high-precision inertial navigation instrument based on the Sagnac effect, the closed-loop fiber optic gyroscope has many advantages, such as large dynamic range, no moving parts and wear parts, high sensitivity, stable and reliable manufacturing process, low cost, suitable for mass production, etc., and has been widely valued and gradually become the main instrument in the field of inertial navigation and strategic applications. However, in order to give full play to the performance advantages of the closed-loop fiber optic gyroscope, it is necessary to match the appropriate control parameters of its control circuit during the production and debugging of the closed-loop fiber optic gyroscope to ensure that the closed-loop fiber optic gyroscope meets the expected performance requirements.

[0003] In the existing closed-loop fiber optic gyroscope production process, it is first necessary to perform environmental stress screening on the closed-loop fiber optic gyroscope control circuit to eliminate defective circuit boards. Because of the need for test signals in the screening test phase, a set of dedicated programmable logic device software suitable for the closed-loop fiber optic control circuit screening mode needs to be loaded during the screening process. After the screening test is completed, the programmable logic device software used in the normal working mode needs to be reloaded. Since the programmable logic device state is changed after the screening is completed, the effectiveness of the screening test process is weakened. At the same time, during the normal working process, due to the different lengths of each closed-loop fiber optic gyroscope fiber ring, different Y waveguide initial values, different angular velocity data output protocols, etc., the closed-loop fiber optic gyroscope control circuit needs to debug and match the control parameters. At present, the debugging of the control parameters of the closed-loop fiber optic gyroscope control circuit is selected by professional debugging personnel in the programmable logic device software with different parameters generated in advance. After the software is loaded, the rationality of the software selection is determined according to the output. If it is not appropriate, the programmable logic device software of other parameters needs to be reloaded until the software version corresponding to the most appropriate parameters is loaded. The operation is complicated and time-consuming, and multiple versions of programmable logic device software are used on site, which is not conducive to process management, resulting in increased costs, reduced efficiency, and low fault tolerance. Therefore, how to solve the problems of the existing technology and simply, efficiently and accurately debug and match the closed-loop fiber optic gyroscope control parameters has become a problem that needs to be solved in engineering practice. Summary of the invention

[0004] Purpose of the invention: To provide a method for adaptively switching the working mode of a closed-loop fiber optic gyroscope control circuit, which is used for a closed-loop fiber optic gyroscope control circuit and aims to solve the problems of complex and inefficient loading, debugging and control parameter matching of closed-loop fiber optic gyroscope programmable logic devices in the existing production process. The screening process, debugging process and delivery of the gyroscope control circuit can be completed by loading the programmable logic device software only once, and the matching of the closed-loop fiber optic gyroscope control circuit parameters can be accurately achieved, thereby improving work efficiency and reducing costs.

[0005] Technical solution:

[0006] A method for adaptively switching the working mode of a closed-loop fiber optic gyroscope control circuit, comprising:

[0007] Step 1: When the control parameters of the closed-loop fiber optic control circuit need to be changed, the host computer and the closed-loop fiber optic gyroscope control circuit communicate with each other through the parameter reading and writing module, send a specific data writing instruction, and complete the parameter writing of the control parameter AK in the EEPROM memory;

[0008] Step 2: Each time the closed-loop fiber optic gyro control circuit is powered on, the control parameters AK stored in the EEPROM memory are read in sequence; the read control parameters AK are added in sequence, and the sum of the control parameters AK is compared with the preset standard value;

[0009] If the sum of the control parameters AK is equal to the preset standard value, it is determined that the closed-loop fiber optic gyroscope is operating in the working mode;
