Detailed Description
The core of the application is to provide a control method, a control device, control equipment, a computer readable storage medium and in-vitro shock wave equipment for single bus communication, which are used for filtering interference signals after single bus data are received.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
Example one
Fig. 1 is a flowchart of a control method for single bus communication according to an embodiment of the present disclosure; fig. 2 is a waveform diagram of normal frame data.
As shown in fig. 1, based on a single bus receiving end, the method for controlling single bus communication provided in the embodiment of the present application includes:
s101: in the process of receiving the serial data bits, when a signal with the duration time not conforming to the preset level duration time is detected, the signal is confirmed to be an interference signal.
S102: and identifying the type of the interference signal according to the preset level duration and the preset identification precision.
S103: and if the types of the interference signals are signals which can be distinguished from the preset high-level signals and the preset low-level signals, discarding the serial data positions after recording the positions of the interference signals.
S104: and if the types of the interference signals are signals which cannot be distinguished from high-level signals and low-level signals, discarding the data frame after the data frame where the interference signals are located is received.
Wherein the preset level duration includes a preset high level duration and a preset low level duration.
The existing single bus communication method usually only starts from a single bus sending end to design a filtering scheme to avoid the generation of interference signals such as burrs and the like, but often cannot completely avoid the generation of the interference signals, and at the moment, the received data needs to be filtered at a single bus receiving end.
In practical applications, the expression of 0 and 1 signals is usually realized by using different combinations of high level duration and low level duration, for example, the manner of generating 1bit data at a single bus transmitting end may be: the high level 80us and the low level 20us are 1 timing, and the high level 20us and the low level 80us are 0 timing. When sending a frame of data, the first header data, the second header data, the address, the data, and the check bits are usually sent with 40 bits of data. In order to prevent data loss or response delay caused by too long time consumption for sending a frame of data, a queue is usually used for sending the data. The signal waveform of one frame data normally transmitted is as shown in fig. 2.
In a specific implementation, for step S101, the single bus sink sets the serial receive pin as an input, enabling to receive interrupts.
In order to match the controllers with different processing speeds, so that the controllers can accurately determine the logic states of the serial data, the receiving serial data bits in step S101 specifically include: and after the receiving interruption, delaying for a third preset time and then starting to read the level state. Wherein the third preset duration is between the preset high level duration and the preset low level duration. For example, according to the above-mentioned high level duration and low level duration being 20us and 80us, respectively, the third preset time period may be set to 30 us.
After receiving 1 data of 8 bits, shifting is carried out, and the data is stored as 1 byte data. When the correct data bit is received, the single bus receiving end starts to count the data bit number in an accumulation manner.
In the process of receiving the serial data bits, identifying an interference signal according to the preset high level duration and the preset low level duration, namely when the duration of the signal is neither the preset high level duration nor the preset low level duration, indicating that the signal is not a normal signal generated by the single bus sending end. For example, when the preset level duration is set to "timing of high level 80us, low level 20us is 1, and timing of high level 20us and low level 80us is 0", if a high level signal of 30us is received, it is considered as an interference signal. On the basis, fault tolerance intervals are set for the preset high level duration and the preset low level duration, for example, 79 us-81 us and 19 us-21 us are all set as the preset level duration, and when the duration of the signal exceeds the fault tolerance interval, the signal is considered as an interference signal.
For step S102, the type of the interference signal is identified according to the preset level duration and the preset identification accuracy. The types of the interference signal are classified into a signal that can be distinguished from a preset high level signal and a low level signal, and a signal that cannot be distinguished from a high level signal and a low level signal. Whether to distinguish is divided by further setting a threshold value of the duration. For example, it may be set that when the difference between the duration of the plurality of interference signals and the duration of the closest preset level is positive and then is smaller than the preset difference, the signals are regarded as being indistinguishable, and when the difference between the duration of the plurality of interference signals and the duration of the closest preset level is positive and then is greater than or equal to the preset difference, the signals are regarded as being distinguishable. On the basis, various ways for identifying the type of the interference signal can be provided, and the design is carried out according to the setting of the duration time of the preset level and the identification precision of the single-bus receiving end.
For easy identification, step S102: identifying the type of the interference signal according to the preset level duration and the preset identification precision, which may specifically be:
and if the duration of the interference signals is between the smaller value and the larger value of the preset high-level duration and the preset low-level duration, determining the type of the interference signals as signals which cannot be distinguished from the high-level signals and the low-level signals, and otherwise determining the type of the interference signals as signals which can be distinguished from the high-level signals and the low-level signals.
For example, when the preset level duration is set as "high level 80us, low level 20us is a 1 time sequence, and high level 20us and low level 80us are 0 time sequences", and the duration of a plurality of interference signals is less than 20us or more than 80us, the interference signals are considered as signals which can be distinguished from high level signals or low level signals; a number of scrambling signals having a duration between 20us and 80us are considered to be signals that are indistinguishable from high or low signals.
For step S103 and step S104, if the interference signals are signals that can be distinguished from the high level signals or the low level signals, the serial data bits when the interference signals occur are discarded after the positions of the interference signals are recorded, so as to avoid the dislocation of the subsequent serial data bits caused by the interference signals. And if the interference signals are signals which cannot be distinguished from the high-level signals or the low-level signals, discarding the whole data frame after the data frame where the interference signals are located is received. And simultaneously, according to the importance degree of the received data, a request for re-providing the data frame can be sent to the single bus sending end at the idle moment of the single bus.
After the data frame where the interference signal is located is received, the data frame is discarded, which may specifically be: and when detecting that the number of bits of serial data bits in the data frame received by the buffer area exceeds half of the number of bits of one frame of data, timing to exceed a first preset time length, determining that the data frame is completely received, and discarding the data frame. The first preset duration is smaller than the sending interval between the data frames. For example, if one frame of data is transmitted at a queue interval of 100ms, it is possible to confirm that a valid frame of data has been received when the number of bits of the frame of data exceeds half of the number of bits of the frame of data, start timing at this time, and when the timing exceeds 30ms, consider that one frame of data has been received and the next frame of data has not been transmitted at this time, clear the received serial data bits and the buffer, and discard the frame of data without affecting the normal reception of the next frame of data. In practical application, when detecting that the bit number of the serial data bits in the data frame received by the buffer exceeds other proportion of the bit number of the frame data, the buffer can confirm that a frame of valid data is received, and estimate that the frame of data is received completely according to the data frame sending interval, and then discard the whole data frame with the two types of burrs.
According to the control method for single bus communication, when a single bus receiving end receives a serial data bit, when an interference signal with duration time not conforming to preset high level duration time and preset low level duration time is detected, the interference signal can be distinguished from the preset high level signal and the preset low level signal according to the preset level duration time and preset identification precision, if the position of the interference signal can be recorded, the serial data bit is discarded, otherwise, after the data frame where the interference signal is located is received, the data frame is discarded. The interference signals in the single-bus serial data frame are identified and classified and removed, and the influence of data dislocation caused by the interference signals on subsequent data reception is avoided, so that the effects of filtering the interference signals from a receiving end and ensuring the quality in single-bus communication are realized.
Example two
FIG. 3 is a waveform illustrating a periodic disturbance on a single bus when a pistol solenoid valve is operating at 10 Hz; FIG. 4 is a waveform illustrating a periodic disturbance on a single bus when a pistol solenoid valve is operating at 5 Hz; FIG. 5 is a waveform illustrating a periodic disturbance on a single bus when a pistol solenoid valve is operating at a frequency of 3 Hz; fig. 6 is a waveform diagram illustrating a periodic interference waveform when data is transmitted on a bus.
In addition, during the working process of the single-bus sending end and the single-bus receiving end, the single-bus sending end and the single-bus receiving end may generate interference signals outside normal data due to electromagnetic interference, and if the interference signals are not identified, the single-bus receiving end may mistakenly recognize the interference signals as the data frames. Use external shock wave equipment as an example, can adopt single bus communication between the host computer controller of external shock wave equipment and the pistol controller, in order to realize that the demonstration between host computer display screen and the pistol display screen is synchronous, because the pistol solenoid valve is opened with certain frequency, can produce the interference pulse of same frequency, when the pistol work, the unable normal clear of communication, if not carry out filtering process, let the user just can the adjusting parameter when the pistol stops, will certainly lead to user experience relatively poor. As shown in fig. 3, 4 and 5, when the solenoid valves of the pistol operate at different frequencies, the single-bus receiver will receive the corresponding periodic interference signal, and the single-bus receiver will mistakenly assume that data is received. As shown in fig. 6, when data is transmitted on the single bus, a periodic interference signal is mixed in a normally transmitted data frame, which results in a disordered reception of the data frame. In the process of single bus transmission, due to the fact that a transmission line is too long, when the single bus transmission is interfered by outside, for example, a pistol electromagnetic valve working at a certain frequency, or accidental noise, because the pulse is fixed or accidental, the number and duration of the pulse are obviously different from those of normally transmitted frame data, and the pulse interference of the fixed frequency and accidental pulse is filtered out by utilizing the difference.
On the basis of the foregoing embodiment, based on the single-bus receiving end, the method for controlling single-bus communication according to the embodiment of the present application further includes:
when a first serial data bit of a data frame is received, detecting the bit number of the received serial data bit after a second preset time length;
and if the bit number of the serial data bit is smaller than the first threshold value, clearing the serial data bit starting from the first serial data bit.
In a specific implementation, timing and bit number measurement are performed from the time when the first serial data bit of a data frame is received, and after the timing exceeds a certain time (for example, one fourth of the total time for normally transmitting one frame of data), according to the number of received data bits in the time, and when the number of received data bits is less than a certain value (the number of received data bits in the time of normally transmitting one frame of data), it can be determined that the received data is not normal frame of data, but is impulse interference, so that impulse interference is filtered out.
In practical application, normally, a frame of data received normally receives about 10 bits of data bits within 2ms after receiving a first serial data bit, so that when the first serial data bit of a data frame is received, the number of the received data bits after timing for 2ms can be detected, if the number of the received data bits is less than 4, an interference signal with discontinuous received data bits is judged, the number count is cleared, the received data is cleared, and the burst and periodic interference signals generated on a single bus outside normal data transmission can be filtered.
EXAMPLE III
Fig. 7 is a schematic diagram of interference waveforms coupled from one single bus transmission to another single bus.
On the basis of the above embodiment, if a single-bus receiving end is connected to multiple single buses, for example, multiple single buses are connected between a pair of single-bus receiving ends and a single-bus transmitting end, or one single-bus receiving end is connected to multiple single-bus transmitting ends through multiple single buses (for example, a host controller is connected to multiple pistol controllers), data transmitted on one single bus may couple an interference waveform on the other single bus, as shown in fig. 7. Mutual coupling interference of transmission data among the multiple paths of single buses cannot be filtered and judged, no filtering mechanism exists after the data are received, and the anti-interference performance is poor.
On the basis of the foregoing embodiment, when the single-bus receiving end is connected to multiple single buses, based on the single-bus receiving end, the method for controlling single-bus communication according to the embodiment of the present application further includes:
and when one single bus is in a transceiving state, closing the receiving interruption of the other single buses.
In a specific implementation, when a single bus sending end needs to send data on one single bus, all external interrupts are closed, and after an IO port is configured to output, one frame of data is sent. The single-bus receiving end carries out time delay processing to prevent self-receiving and configures the IO back into input. The single bus receiving end and the single bus sending end both start appointed external interruption, and the interruption starting is mutually exclusive, so that when data is sent on one single bus, the interruption receiving of the other single bus can not be started.
Taking the example that the single bus receiving end is connected with two single buses, when two single buses are used for data transmission at the same time, a transmission signal on one single bus can couple out a corresponding weak signal on the other single bus, and if the transmission signal is not processed, wrong reception on the other single bus can be caused.

calculating a check value of the preset data according to a preset check method, comparing the check value with the read check value, and if the check value is consistent with the read check value, determining that the data frame is correctly received; if not, confirming the data frame receiving error and abandoning the data frame.
In the first embodiment, when sending a frame of data, the first header data, the second header data, the address, the data, and the check bits are usually sent first for 40 bits of data. In this regard, after performing interference filtering on data based on the above embodiment, the data is placed in the buffer, and after completing receiving a complete frame of data, the subsequent processing is performed. From the reception of the first byte data of a data frame, the previous two byte data are compared with the first header data and the second header data to determine whether the correct data frame is received. After receiving the correct data frame, the data frame is continuously received until receiving byte data with preset length, the data frame is read and transferred to another storage position after determining that the data frame is completely received.
And further checking the correctness and the integrity of the data frame by using the check code of the appointed bit number in the data frame. And calculating a check value of preset data (data with preset digits) according to a preset check method (such as exclusive-or check), comparing the check value with the check value stored in the preset data bits of the data frame, if the check values are consistent, indicating that the whole frame of data is correctly received, and otherwise, discarding the frame of data.
