Description

Technical Field

[0001] This invention relates to the field of mobile communication circuit board technology, and in particular to a method and apparatus for determining communication time intervals. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] When existing circuit boards communicate, a pre-agreed communication time interval is required, and message transmission and reception are performed according to this agreed-upon interval. For example, when circuit board 1 and circuit board 2 communicate, circuit board 2 immediately initiates DMA data transmission upon receiving data, transferring the received data to memory for buffering. Simultaneously, a timer (Timer1) is started as a watchdog timer for the T and R data transmissions of this communication, monitoring whether a timeout occurs during the data communication. The timeout period (Timeout1) of timer 1 is determined based on the baud rate (B) of circuit board 1, the length of a single data transmission (Bit), and the transmission interval delay (sleep), calculated as: Timeout 1 = 1.1 * (Bit / B + sleep) + T_offset, in seconds. Here, T_offset is the internal machine clock cycle of circuit board 2, representing the minimum cycle for a single-step operation of the chip within that circuit board. Circuit board 1 receives data simultaneously with each data transmission, then sleeps for the delay period before starting the next data transmission. The time interval between two adjacent data communication messages R varies due to timing deviations and changes in program task processing, causing circuit board 2 to be unable to accurately predict the data arrival time, resulting in problems such as data not being ready and data communication slowing down.

[0029] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, further detailed description of the embodiments of the present application will be given below with reference to the accompanying drawings. Herein, the schematic embodiments of the present application and the descriptions thereof are used to explain the present application, but not to limit the present application.

In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B and C can mean including any one or more elements selected from the set consisting of A, B and C.

The description of the terms "one embodiment", "one specific embodiment", "some embodiments", "for example", and the like means that the specific features, structures, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.

The order of the steps involved in each embodiment is used to illustrate the implementation of the present application, and the order of the steps is not limited. The order can be adjusted as needed.

[0033] It is found through research that when the circuit boards communicate, the communication time interval needs to be agreed in advance, and the message transmission and reception is carried out according to the agreed time interval. For example, when circuit board 1 and circuit board 2 communicate, circuit board 2 starts DMA data transmission immediately after receiving data each time, and transmits the received data to the memory for buffering, and starts a timer Timer 1 as a watchdog for this time communication message T and R data transmission, for monitoring whether the current data communication is timed out. The timeout time Timeout 1 of the timer 1 is determined according to the baud rate B of the circuit board 1, the single data transmission length Bit, and the transmission interval delay sleep, and the calculation method is: Timeout 1 = 1.1*(Bit / B+sleep)+T_offset, unit: second. Wherein, T_offset is the internal machine clock period of the circuit board 2, which represents the minimum period of the single step running of the internal chip of the circuit board. Circuit board 1 receives data at the same time of sending data each time, and then sleeps for a delay time, and then starts the next data transmission. The interval time of adjacent two data communication messages R changes due to timing deviation, program task processing, etc., which causes the circuit board 2 to be unable to accurately predict the data arrival time, and thus problems such as data not being ready and slow data communication occur.

[0034] In view of the above research, as shown in Figure 1 The embodiment of the present application provides a communication time interval determination method, which comprises:

[0035] S101: According to the timer of the circuit board, the actual interval time information corresponding to the historical message data of different message lengths is obtained; wherein, the actual interval time information includes: the interval time of each adjacent data transmission in the historical message data;

[0036] S102: determining an interval time jitter value of each adjacent data transmission in each historical message data according to a preset interval duration corresponding to each historical message data and actual interval duration information corresponding to each historical message data; wherein the preset interval duration corresponding to each historical message data is a timeout duration of a timer of the circuit board pre-set;

[0037] S103: 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;

[0038] S104: fitting the message length and the average interval time jitter value of each historical message data by using an exponential decay method to obtain an interval time jitter value prediction model;

[0039] S105: inputting the message length of the to-be-received message data into the interval time jitter value prediction model to obtain an interval time jitter value corresponding to the to-be-received message data;

[0040] S106: determining a communication time interval corresponding to the to-be-transmitted data according to the interval time jitter value corresponding to the to-be-received message data.

[0041] In the embodiment of the application, the actual interval duration information corresponding to the historical message data of different message lengths is obtained according to the timer of the circuit board; wherein the actual interval duration information includes: the interval duration of each adjacent data transmission in the historical message data; the interval time jitter value of each adjacent data transmission in each historical message data is determined according to the preset interval duration corresponding to each historical message data and the actual interval duration information corresponding to each historical message data; wherein the preset interval duration corresponding to each historical message data is a timeout duration of a timer of the circuit board pre-set; the average interval time jitter value of each historical message data is determined 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; the message length and the average interval time jitter value of each historical message data are fitted by using an exponential decay method to obtain an interval time jitter value prediction model; the message length of the to-be-received message data is input into the interval time jitter value prediction model to obtain an interval time jitter value corresponding to the to-be-received message data; and a communication time interval corresponding to the to-be-transmitted data is determined according to the interval time jitter value corresponding to the to-be-received message data. In this way, the communication time interval can be adjusted in time according to the transmission message length between the circuit boards, the normal transmission of message data between the circuit boards is ensured, and the flexibility of the communication mode between the circuit boards is improved.

[0042] The communication time interval determination method is described in detail below.

[0043] For the above S101, the message data length transmitted between the circuit boards can be different, and each message data includes data such as message header identification, message length, message content, and check code. When transmitting the message data between the circuit boards, the message header identification 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 the circuit board receives one of the message data, the DMA data transmission is started immediately to transmit the received data to the memory for buffering, and a timer is started at the same time as the watchdog of the data transmission of the message data for monitoring whether the data communication is timed out.

[0044] Specifically, each adjacent data transmission in the message data is separated by a certain time length. For example, since SPI belongs to a full-duplex synchronous serial communication method, when the circuit board 1 and the circuit board 2 use SPI communication, the sender transmits 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 at the same time when receiving the data. Therefore, the circuit board 2 feeds back a data immediately after receiving the message header identification, but the data has no meaning. After a certain time, the circuit board 2 feeds back another feedback data to the circuit board 1 to indicate that the message header identification has been received. The time length between the time when the message header identification is received (i.e. the time when the invalid data is fed back) and the time when the feedback data is transmitted is the time length of the adjacent data transmission in the message data.

[0045] In order to better determine the communication interval time length between the two circuit boards in communication, the actual interval time length information corresponding to the historical message data of different message lengths between the two circuit boards in communication needs to be obtained from any one of the two circuit boards in communication. The actual interval time length information includes the interval time length of each adjacent data transmission in the historical message data.

[0046] For the above S102, the preset interval time length corresponding to each historical message data is the timeout time length of the timer of the circuit board.

[0047] In an embodiment of the present application, the interval time jitter value of each adjacent data transmission in each historical message data is determined according to the preset interval time length corresponding to each historical message data and the actual interval time length information corresponding to each historical message data. For example, for each historical message data, the interval time jitter value of each adjacent data transmission in the historical message data is obtained by subtracting the interval time length of each adjacent data transmission in the historical message data from the preset interval time length corresponding to the historical message data.

[0048] For example, the timer Timer1 of the circuit board records the interval time sleep of the adjacent two data transmissions, before starting the timer for the second time, the actual timer count value TimeStill of Timer1 is read, and the jitter value Ti of the interval time of this time is obtained by subtracting TimeStill from the timeout time Timeout1 of Timer1.

[0049] For the above S103, as shown in the method flowchart provided by the embodiment of the application for determining the 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, comprising: Figure 2

[0050] S201: determining the interval time data quantity corresponding to the historical message data according to the historical message data length.

[0051] For example, the historical message data transmitted by the circuit board includes data R1-Rm, 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 so on, and then a total of m-1 communication interval jitters are recorded.

[0052] S202: adding the interval time jitter value of each adjacent data transmission in the historical message data to obtain the interval time jitter value sum of the historical message data.

[0053] S203: dividing the interval time jitter value sum 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.

[0054] For example, as shown in Table 1, the relationship between the message length of the historical message data and the average interval time jitter value is provided as an example table by the embodiment of the application.

[0055] Table 1

[0056]

[0057]

[0058] For the above S104, the message length and the average interval time jitter value of each historical message data are fitted by using the exponential decay method to obtain the interval time jitter value prediction model, comprising:

[0059] ​According to the message length of each historical message data and the average interval time jitter value, an exponential function is fitted to obtain the model parameters of the interval time jitter value prediction model, and the interval time jitter value prediction model is obtained according to the model parameters of the interval time jitter value prediction model:

[0060]

[0061] Wherein, T is the average interval time jitter value corresponding to the historical message data, n is the message length corresponding to the historical message data, k and τ are the model parameters of the interval time jitter value prediction model.

[0062] Specifically, as shown in Figure 3 The horizontal axis represents the message length n, and the vertical axis represents the average interval time jitter value T. As the message length n increases, the communication interval time jitter value T(i) gradually increases, and the average interval time jitter value T of the interval time jitter value T(i) gradually decreases with the increase of n. The exponential decay method is used for fitting to identify the key parameters k and τ of the communication time interval.

[0063] The standard exponential function The function curve is shown in Figure 4 The time t ranges from 0.001 to 10, and the purpose is to estimate the value of the exponential function T at 0 time. The correct standard value is 1.

[0064] In actual situations, it is impossible to obtain all the decay process data, or even a decay time curve of about 10 times. Therefore, in the exponential regression process, a continuous decay process of about 3 times the decay time is also used to simulate the actual situation. Considering the 3 times decay time, because the function value has decayed to 5% of the initial value within the initial 3 times decay time, it meets the international standard principle of 3 sigma.

[0065] The purpose of the exponential regression is to identify The time is taken as the reference, and the purpose is to identify the parameters after The error absolute value of the actual value Y is minimum, so the fitting is closest. In actual process, both the actual value N and the time T will be disturbed, and both will have jitter, which will cause fitting error and consistent effect. Only the time is considered correct here, and the analog measurement value is disturbed; on the one hand, the time reference crystal of the DSP is relatively high, so the time deviation is small; on the other hand, the error percentage of the analog measurement value is relatively large compared with the time. Without adding a disturbance signal, the data of the first 3 seconds is analyzed, and the fitting parameters obtained by using the least square method are completely standard exponential functions without any deviation; the last 3 seconds of data is analyzed, and the least square method is used for fitting, which also reproduces the standard exponential function. Here, it is close to mathematical analysis, so there is no computer truncation error commonly seen in numerical algorithms. Add a 0.5% random noise signal, analyze the first 3 seconds of data and the last 3 seconds of data again, and then perform least square fitting, use the estimated parameters to perform exponential regression at time 0, and compare with the standard value to analyze the error. The processing result of the first 3 seconds of data is: y0 is 0.995173; dist is 0.482739%. The processing result of the last 3 seconds of data is: y0 is 0.007747; dist is 99.225281%.

[0066] The actual simulation result verifies the original theoretical analysis. The same analog quantity disturbance signal has obvious interference on the small signal, resulting in a very large exponential regression deviation, which far exceeds the acceptable range; and the same analog quantity disturbance signal has little interference on the algorithm, and the data estimation result is very accurate.

[0067] For the above S105, when the circuit board receives the message length of the to-be-received message data, the message length L of the to-be-received message data is input into the following trained interval time jitter value prediction model:

[0068]

[0069] Wherein, k, and τ are model parameters known to the interval time jitter value prediction model through the training of the above S104, and n=L is used to calculate the interval time jitter value T corresponding to the to-be-received message data.

[0070] For the above S106, according to the interval time jitter value corresponding to the to-be-received message data, the communication time interval corresponding to the to-be-transmitted data is determined, for example, including: adding the timeout length of the timer of the circuit board to the interval time jitter value corresponding to the to-be-received message data to obtain the communication time interval corresponding to the to-be-transmitted data.

[0071] This invention also provides a communication time interval determination device, as described in the following embodiments.
