All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The data of the fiber-optic gyroscope generally has 20 bits, the parallel transmission mode occupies more interface resources, the hardware design aspect is complex, bus communication needs to be designed, generally, when the strapdown inertial navigation system is formed, the used gyros, accelerometers and other sensors are more, the data volume is large, and therefore the serial data transmission mode is often adopted.
When the multi-channel fiber-optic gyroscope is used in a servo platform or a strapdown inertial navigation system, the original communication mode is that the multi-channel gyroscope is respectively carried out by own exclusive channels. When data of multiple gyros are sent to a system for processing through a single channel in real time, the data of the multiple gyros at the same time must be put together and do not interfere with each other.
When the platform carries a plurality of gyros to sense the attitude in real time, the data of the multi-axis gyros are required to be sent out to the processing end with low delay, and at the moment, the communication mode has multi-path independent output and single-path output. Therefore, the embodiment of the invention provides a single-channel communication method and a single-channel communication device for a multi-axis fiber-optic gyroscope, wherein each axis of the multi-axis fiber-optic gyroscope is a level MAX3490 of a data signal sent by a respective FPGA, the level MAX3490 is converted into a level in an RS422 form, the MAX3490 has a sending and receiving function, data of other channels of gyroscopes are sent to any specified channel RX end of the multi-axis fiber-optic gyroscope from TX ends of respective MAX3490 chips, and the channels of data are combined by the FPGA of the channel and then serially sent out real-time data of multiple channels of gyroscopes. The single-channel output mode is to frame and synchronously send the angular rate bytes of the multi-channel gyroscope to the receiving terminal, so that the required hardware quantity is reduced, and the receiving terminal can conveniently process the data in the next step. The following description and description will proceed with reference being made to various embodiments.
FIG. 1 is a flow chart of a single-channel communication method of a multi-axis fiber-optic gyroscope according to an embodiment of the invention; fig. 2 is a specific flowchart illustration of a multi-axis fiber-optic gyroscope single-channel communication method according to an embodiment of the invention. Fig. 1 and fig. 2 provide a single-channel communication method for a multi-axis fiber-optic gyroscope according to an embodiment of the present invention, including:
when data of a plurality of paths of multi-axis optical fiber gyroscopes are transmitted to a receiving pin RX end of any appointed output multi-axis optical fiber gyroscope through a TX end of a serial port chip pin, the data of the output multi-axis optical fiber gyroscopes are synchronously generated;
the output multi-axis fiber optic gyroscope recombines and sends out the data at the same moment in a single path through the serial port chip.
In this embodiment, as a preferred embodiment, when the platform carries a plurality of gyros and senses the attitude in real time, it is required to send data of the multi-axis gyro to the processing terminal with low delay, and in this case, the communication method has a multi-path independent output and a single-path output. The single-channel output mode is to frame and synchronously send the angular rate bytes of the multi-channel gyroscope to the receiving terminal, so that the required hardware quantity is reduced, and the receiving terminal can conveniently process the data in the next step. By utilizing the transmitting and receiving functions of the MAX3490 chip, the data can be flexibly combined in a transmitting mode, and the data of a plurality of axes of the gyroscope can be uniformly transmitted by any axis in the multi-axis gyroscope. Meanwhile, the gyro data can be flexibly adjusted according to bytes.
On the basis of the above embodiment, the method for transmitting data of a multi-channel multi-axis fiber optic gyroscope to the front of the RX end of the receiving pin of any specified output multi-axis fiber optic gyroscope through the TX end of the serial chip pin further includes:
each axis of the multi-axis fiber-optic gyroscope is a level of a data signal sent by a respective FPGA (Field Programmable Gate Array) and converted into a level in the form of RS422 through a serial port chip MAX 3490.
In this embodiment, as a preferred embodiment, a UART transmitting/receiving FPGA implementation is introduced in a 10-bit serial communication manner. In practical use, when the equipment platform uses two or three to form a two-axis or three-axis system for measurement, the number of each gyro is divided into two or three serial ports to be independently output according to the requirement of an demander, and multi-path gyro data integration single-path output can also be provided. When the number of the multiple gyros is integrated into a single channel and provided for the system, the gyros realize the communication between the board level and the PC end through MAX3940 on the aspect of hardware construction.
Each axis of the multi-axis gyroscope is a data signal level MAX3490 sent by each FPGA and converted into a level in an RS422 mode, the MAX3490 has the functions of sending and receiving, the data of other paths of gyroscopes are sent to any appointed path of RX end of the multi-axis gyroscope from the TX end of each MAX3490 chip, and the data are combined by the FPGA of the path and then are sent out by the paths of the RX end and the RX end in series.
On the basis of the above embodiments, when data of the multi-channel multi-axis fiber optic gyroscope is sent to a receiving pin RX end of any designated output multi-axis fiber optic gyroscope through a TX end of a serial chip pin, the method further includes:
when one frame of data of the multi-path multi-axis fiber-optic gyroscope is sent out, a Universal Asynchronous Receiver/Transmitter (UART) with an FIFO (First Input First Output) memory receives one frame of data according to bytes, then a signal that rxready is 1 is sent out to the FIFO memory, and a Din pin of the FIFO memory receives one frame of data for buffering.
In this embodiment, as a preferred implementation manner, multiple paths of data of the multi-axis fiber-optic gyroscope are combined into one path to interact with a previous-level system, and it is required that data of different paths of the multi-axis fiber-optic gyroscope are sent synchronously without delay and do not generate mutual interference. The hardware structure takes two gyros as an example, the data of the gyro B is sent to the receiving pin RX end of the gyro A through the pin TX end of the serial port chip MAX3490, when one frame of data of the gyro B is sent out, the UART with the FIFO memory firstly judges the state of RX and idle, then sends out a signal that rxready is 1 to the FIFO memory after one frame of data is received according to bytes, and the Din pin of the FIFO memory receives the data for caching.
In this embodiment, as a preferred embodiment, the interrupt method is simpler and more efficient than the polling method in performing UART communication. However, if there is no FIFO memory, the process is interrupted once for every data transmission (5-8 bits), which is still inefficient. If a FIFO memory is available, an interrupt may be generated after several data (up to 14) are received and transmitted in succession and then processed together. This greatly improves the transceiving efficiency. Since UARTs transmit asynchronously, no synchronous clock is transmitted. In order to ensure the correctness of data transmission, the UART uses a clock with 16 times of the data baud rate for sampling. Each data has 16 clock samples, and the middle sample value is taken to ensure that the samples cannot be in a sliding code or an error code. The number of data bits of a frame of UART is generally 8, so that the receiving end can correctly sample data even if each data has an error of one clock.
The double-axis adopts more data baud rates of 115200bps and a gyrotron crystal oscillator of 50 MHz. The frequency of the required clock is 16 x 115200. The system clock is 50MHz, and the division coefficient is 50000000/(16 × 115200) ═ 27.13, and the integer is 27.
The multi-axis gyroscope realizes that signals are output from one path, namely, a certain axis can be used as a mother board, signals of other axes are received by the multi-axis gyroscope, and after identification bits are made in data bytes, a plurality of paths of data at the same moment are combined to form new frame data. Therefore, the design of data receiving and transmitting of the motherboard is complex, when data is received, if more than two paths of data are received through one path of channel, the data need to pass through in sequence and cannot be overlapped or lost, and the completeness of the data in the design time period is ensured. And after receiving the data of other axis gyros, adding and combining the simultaneous data of the 'mother board' gyro to form complete sensitive rate information containing the multi-axis gyro.
On the basis of the above embodiments, before the UART with the FIFO memory receives one frame of data in bytes, the method further includes:
the UART with the FIFO memory acquires the status of rx and idle, and receives data if rx is found to be 0 and idle is found to be 0.
In this embodiment, as a preferred embodiment, data of gyro B is sent to a receiving pin RX of gyro a through a pin TX of a serial port chip MAX3490, when one frame of data of the B gyro is sent out, the UART with FIFO first determines the status of RX and idle, and if it determines that RX is 0 and idle is 0, after receiving one frame of data by byte, sends a signal that RX is 1 to the FIFO, and then the Din pin of the FIFO receives the data and buffers it.
On the basis of the above embodiments, the method further includes:
when the FIFO memory receives the data, an enable signal with Txout equal to 1 is generated, and one frame of data is received completely.
In this embodiment, based on the above-described flow of each embodiment, the a gyro completes reception of data of the B gyro in one frame per byte. The data format of A, B gyro is adjusted to make the data refresh rate of both strictly the same, for example, 2 ms generates one number, but the data pulse of A gyro is concentrated in the first 1 ms of the 2 ms, and the data pulse of B gyro is concentrated in the second 1 ms of the 2 ms. When the A gyro receives the data of the B gyro into the FIFO buffer of the A gyro, the data of the A gyro is generated.
On the basis of the above embodiments, the outputting multi-axis fiber optic gyroscope recombines and transmits data at the same time in a single path through a serial port chip according to a frame, and specifically includes:
and outputting the multi-axis optical fiber gyroscope to acquire a sending preparation state, if receiving an enabling signal of Txout being 1 sent by the FIFO memory, judging that wrsig being 1 and idle being 0 are obtained, recombining the data at the same moment according to frames and sending the data through a serial port chip in a single path.
In the embodiment, as a preferred implementation mode, the FPGA of the a gyro controls the A, B gyro to be recombined together in frames at the same time, so as to form a new data structure. And the A gyro judges and sends a ready state, an enable signal of which the Txout is 1 is generated when FIFO cache data is finished, and finally, the gyro A sends the combined data in a single path through a serial port chip.
