It is found that when the circuit boards communicate with each other, a predetermined time interval is required for communication, and the message is sent and received according to the predetermined time interval. For example, the circuit board 1 communicates with the circuit board 2, and after receiving data, the circuit board 2 immediately starts DMA data transmission, and transmits the received data to the memory for buffering, and simultaneously starts a Timer1 as a watchdog for data transmission of the present communication messages T and R, so as to monitor whether the present data communication has overtime. The Timeout time Timeout1 of the timer1 is determined according to the baud rate B, the single-time data transmission length Bit and the transmission interval delay of the circuit board 1, and the calculation method is as follows: timeout1 = 1.1 (Bit/B+sleep) +T_offset in seconds. Wherein t_offset is the clock period of the machine inside the circuit board 2, and represents the minimum period of single-step operation of the chip inside the circuit board. The circuit board 1 receives data while transmitting data each time, and then sleeps for delay time, and starts the next data transmission again. The interval time of the adjacent 2 data communication messages R causes time variation of program task processing and the like due to timing deviation, so that the circuit board 2 cannot accurately predict the arrival time of data, and the problems of data preparation, data communication slowing and the like occur.
For the above study, as shown in fig. 1, an embodiment of the present invention provides a method for determining a communication time interval, including:
s101: acquiring actual interval duration information corresponding to historical message data with different message lengths according to a timer of the circuit board; the actual interval duration information comprises: the interval duration of each adjacent data transmission in the historical message data;
s102: determining an interval time jitter value of each adjacent data transmission in each historical message data according to a preset interval time length corresponding to each historical message data and actual interval time length information corresponding to each historical message data; the preset interval duration corresponding to each historical message data is the timeout duration of a preset timer of the circuit board;

s106: and determining a communication time interval corresponding to the data to be transmitted according to the interval time jitter value corresponding to the data of the message to be received.
According to the embodiment of the invention, according to the timer of the circuit board, the actual interval duration information corresponding to the historical message data with different message lengths is obtained; the actual interval duration information comprises: the interval duration of each adjacent data transmission in the historical message data; determining an interval time jitter value of each adjacent data transmission in each historical message data according to a preset interval time length corresponding to each historical message data and actual interval time length information corresponding to each historical message data; the preset interval duration corresponding to each historical message data is the timeout duration of a preset timer of the circuit board; determining an average interval time jitter value of each historical message data according to the interval time jitter value of each adjacent data transmission in each historical message data and the message length of each historical message data; fitting the message length of each historical message data and the average interval time jitter value by adopting an exponential decay method to obtain an interval time jitter value prediction model; inputting the message length of the message data to be received into an interval time jitter value prediction model to obtain an interval time jitter value corresponding to the message data to be received; and determining a communication time interval corresponding to the data to be transmitted according to the interval time jitter value corresponding to the data of the message to be received. Therefore, the communication time interval can be timely adjusted according to the length of the transmission messages between the circuit boards, normal transmission of message data between the circuit boards is ensured, and the flexibility of the communication mode between the circuit boards is improved.
The above-described communication time interval determination method will be described in detail.
For S101, the lengths of the message data transmitted between the circuit boards may be different, and the data included in each message data includes, for example: when transmitting message data between circuit boards, the message header identifier is transmitted first, then the message length is transmitted, then the message content of the message length is transmitted, and finally the check code is transmitted. After receiving one data in the message data, the circuit board immediately starts DMA data transmission, transmits the received data to the memory for buffering, and simultaneously starts a timer as a watchdog of the data transmission of the message data, and is used for monitoring whether overtime occurs in the data communication.
Specifically, each adjacent data transmission in the message data will be separated by a certain period of time, for example, because the SPI belongs to a full duplex synchronous serial communication method, when the circuit board 1 and the circuit board 2 adopt SPI communication, the sender sends the first 16-bit data (i.e. 2 bytes or 1 word) in the message data, and the receiver feeds back a 16-bit data synchronously when receiving the data. Therefore, after the circuit board 2 receives the message header identifier, a piece of data is fed back immediately, but the data has no meaning, after the circuit board 2 reacts for a certain time, a piece of feedback data indicating that the message header identifier has been received is fed back to the circuit board 1 according to the message header identifier, and the time between the time when the message header identifier is received (i.e. the time when the invalid data is fed back) and the time when the feedback data is sent is the time length of the transmission interval of the adjacent data in the message data.
In order to better determine the communication interval duration between two communication circuit boards, acquiring actual interval duration information corresponding to historical message data with different message lengths between two communication circuit boards from any one of the two communication circuit boards; the actual interval duration information comprises: the time duration of each adjacent data transmission interval in the historical message data.
For S102, the preset interval duration corresponding to each history packet data is the timeout duration of the timer of the preset circuit board.
In an embodiment of the present invention, determining an interval time jitter value of each adjacent data transmission in each historical packet data according to a preset interval time length corresponding to each historical packet data and actual interval time length information corresponding to each historical packet data includes: and subtracting the interval duration of each adjacent data transmission in the historical message data by adopting the preset interval duration corresponding to the historical message data aiming at each historical message data to obtain the interval time jitter value of each adjacent data transmission in the historical message data.
For example, the Timer1 of the circuit board records the interval duration sleep of 2 adjacent data transmissions, and before the Timer is started for the second time, the actual count value TimeStill of the Timer1 is read, and the Timeout value Timeout1 of the Timer1 is used to subtract TimeStill, which is the jitter value Ti of the interval duration.
For S103, as shown in fig. 2, a flowchart of a method for determining an average interval time jitter value of each historical packet data according to an interval time jitter value of each adjacent data transmission in each historical packet data and a packet length of each historical packet data according to an embodiment of the present invention is provided, where the method includes: for each historical message data:
s201: and determining the interval time data quantity corresponding to the historical message data according to the length of the historical message data.
For example, the historical message data transmitted by the circuit board comprises data R1-Rm, and the SPI communication interval time jitter between the transmission messages R1 and R2 is T1; the SPI communication interval time jitter between the transmission messages R2 and R3 is T2, and the like, m-1 communication interval jitter is recorded in total.
S202: and adding the interval time jitter values of each adjacent data transmission in the historical message data to obtain the sum of the interval time jitter values of the historical message data.
S203: dividing the sum of the interval time jitter values of the historical message data by the interval time data quantity corresponding to the historical message data to obtain the average interval time jitter value of the historical message data.
For example, as shown in table 1, an exemplary table of the relationship between the message length and the average interval time jitter value of the historical message data is provided in the embodiment of the present invention:
TABLE 1
For the above S104, fitting the message length of each historical message data and the average interval time jitter value by using an exponential decay method to obtain an interval time jitter value prediction model, including:
fitting the following exponential functions according to the message length of each historical message data and the average interval time jitter value to obtain model parameters of an interval time jitter value prediction model, and obtaining the interval time jitter value prediction model according to the model parameters of the interval time jitter value prediction model:
wherein T is an average interval time jitter value corresponding to the historical message data, and n is a message length corresponding to the historical message data, and k and τ are model parameters of an interval time jitter value prediction model.
Specifically, as shown in fig. 3, the horizontal axis represents the report Wen Changdu n, the vertical axis represents the average interval time jitter value T, the communication interval time jitter value T (i) increases gradually as the message length n increases, the average interval time jitter value T of the interval time jitter value T (i) decreases gradually as n increases, and the key parameters k and τ of the communication interval are identified by fitting with an exponential decay method.
Using standard exponential functionsThe function curve is shown in fig. 4, and the time T ranges from 0.001 to 10, so as to estimate the value of the exponential function T at the time 0, and the correct standard value is 1.
In practical situations, all attenuation process data, even about 10 times of attenuation time curve, cannot be obtained, so that a section of continuous attenuation process, about 3 times of attenuation time, is adopted in the exponential regression process to simulate the practical situations. The 3-fold decay time is considered because the function value has decayed to 5% of the initial value within the initial 3-fold decay time, satisfying the international standard principle of 3 sigma.
The purpose of exponential regression is to identifyTime-based, the aim is to identify parameters before->The absolute value of the error from the actual value Y is the smallest and the fit thus obtained is the closest. In the actual process, the actual value N and the time T both have interference and jitter, the fitting error is caused, and the effect is consistent. Only the correct time is considered, and the analog measurement is interfered; on one hand, the time reference crystal oscillator of the DSP is considered to be higher, so that the time deviation is small; on the other hand, the deviation is larger in consideration of the error percentage of the analog measurement value compared with time. Under the condition that no interference signal is added, analyzing data of the first 3 seconds, and fitting by using a least square method, wherein the obtained fitting parameters are completely standard exponential functions without any deviation; the final 3 seconds of data was analyzed and fitted using the least squares method, again reproducing the standard exponential function. Here, it is relatively close to mathematical analysis, so that no numerical algorithm is commonly foundComputer truncation errors occur. Adding 0.5% of random noise signals, analyzing the first 3 seconds of data and the last 3 seconds of data again, then performing least square fitting, performing exponential regression on the moment 0 by using estimated parameters, and performing comparison error analysis with a standard value. The first 3 seconds of data processing results are: y0 is0.995173; distis 0.482739%. The last 3 seconds data processing result is: y0 is 0.007747; distis 99.225281%.
The actual simulation result verifies the original theoretical analysis, the same analog quantity interferes signals, the small signal interference is obvious, and the resulting exponential regression deviation is very large, which is far beyond the acceptance range; the same analog interference signal has small interference to the algorithm aiming at the exponential regression algorithm, and the accuracy of the data estimation result is high.
For the above S105, when the circuit board receives the message length of the message data to be received, the message length L of the message data to be received is input into the following trained interval time jitter value prediction model:
the training of k and τ in S104 is performed to calculate the interval time jitter value T corresponding to the message data to be received according to n=l, which is a model parameter known to the interval time jitter value prediction model.
