Detailed Description
The core of the application is to provide a control method, a device, equipment, a computer readable storage medium and an external shock wave equipment for single bus communication, which are used for filtering interference signals after receiving single bus data.
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Example 1
Fig. 1 is a flowchart of a control method of single bus communication according to an embodiment of the present application; fig. 2 is a waveform diagram of normal one-frame data.
As shown in fig. 1, based on a single bus receiving end, the control method for single bus communication provided in the embodiment of the present application includes:
s101: in the process of receiving serial data bits, when a signal with the duration not conforming to the preset level duration 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: the types of the plurality of disturbing signals are signals which can be distinguished from a preset high-level signal and a preset low-level signal, and serial data bits are discarded after the positions of the disturbing signals are recorded.
S104: the types of the interference signals are signals which cannot be distinguished from the high-level signals and the low-level signals, and the data frames are discarded after the data frames where the interference signals are located are received.
Wherein the preset level duration includes a preset high level duration and a preset low level duration.
In the existing single-bus communication method, a filtering scheme is designed to avoid generation of interference signals such as burrs only from a single-bus transmitting end, but the generation of the interference signals cannot be completely avoided, and at the moment, the interference signals need to be filtered on received data at a single-bus receiving end.
In practical applications, the expression of the 0, 1 signal is usually implemented by using different combinations of high-level duration and low-level duration, for example, the manner of generating 1bit data at the single bus transmitting end may be: the high level 80us and the low level 20us are 1 time sequences, and the high level 20us and the low level 80us are 0 time sequences. When transmitting one frame of data, the first frame header data, the second frame header data, the address, the data and the check bits are generally transmitted for 40 bits. In order to prevent data loss or untimely response caused by excessively long time for transmitting a frame of data, the data is usually transmitted by adopting a queue. The signal waveform of one frame of data normally transmitted is as shown in fig. 2.
In particular implementations, for step S101, the single bus receiver sets the serial receive pin as an input, enabling the reception interrupt.
In order to match the controllers with different processing speeds, so that the controllers accurately determine the logic state of the serial data, the receiving serial data bits in step S101 are specifically: and after the receiving interrupt is entered, delaying for a third preset time period and then starting to read the level state. Wherein the third preset duration is between a preset high level duration and a preset low level duration. For example, according to the high level duration and the low level duration described above of 20us, 80us, respectively, the third preset time period may be set to 30us.
After each time 1 8bit data is received, shifting is performed, and the data is stored as 1 byte data. When the correct data bit is received, the single bus receiving end starts to accumulate and count the data bit.
During the process of receiving serial data bits, the interference signal is identified 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, the signal is not a normal signal generated by a single bus transmitting end. For example, when the preset level duration is set to "high level 80us, low level 20us is 1 time sequence, high level 20us, low level 80us is 0 time sequence", if a high level signal of 30us is received, the signal is regarded as an interference signal. On this basis, a fault tolerance interval is set for the preset high level duration and the preset low level duration, for example, 79us to 81us and 19us to 21us are set as preset level durations, and the signal is considered as an interference signal when the duration of the signal exceeds the fault tolerance interval.
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 signals are classified into signals that can be distinguished from preset high-level signals and low-level signals, and signals that cannot be distinguished from high-level signals and low-level signals. The distinction is made by further setting a threshold value for the duration. For example, it may be set that the signal that cannot be distinguished is considered when the difference between the duration of the plurality of scrambling signals and the nearest preset level duration is smaller than the preset difference after the difference is positive, and the signal that can be distinguished is considered when the difference between the duration of the plurality of scrambling signals and the nearest preset level duration is greater than or equal to the preset difference after the difference is positive. On the basis, various ways for identifying the type of the interference signal can be adopted, and the design is carried out according to the setting of the duration of the preset level and the identification precision of the single bus receiving end.
For easy recognition, step S102: the type of the interference signal is identified according to the preset level duration and the preset identification precision, which can be specifically:
the duration of the number of disturbing signals is between a smaller value and a larger value of the preset high level duration and the preset low level duration, the type of disturbing signals is determined as a signal indistinguishable from the high level signal and the low level signal, otherwise the type of disturbing signals is determined as a signal distinguishable from the high level signal and the low level signal.
For example, when the preset level duration is set to "high level 80us, low level 20us is 1 time sequence, high level 20us, low level 80us is 0 time sequence", when the duration of several disturbance signals is smaller than 20us or larger than 80us, it is considered as a signal that can be distinguished from a high level signal or a low level signal; when the duration of the number of disturbing signals is between 20us and 80us, it is considered as a signal which is indistinguishable from a high level signal or a low level signal.
For step S103 and step S104, if the plurality of interference signals are signals that can be distinguished from the high level signal or the low level signal, after the position of the interference signal is recorded, the serial data bits when the interference signal occurs are discarded, so that the subsequent serial data bits are prevented from being misplaced by the interference signal. The interference signals are signals which cannot be distinguished from the high-level signals or the low-level signals, and after the data frame where the interference signals are located is received, the whole data frame is abandoned. Meanwhile, according to the importance degree of the received data, a request for providing the data frame again can be sent to a 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: when the fact 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 is detected, after the timing exceeds a first preset duration, the data frame is determined to be received, and the data frame is discarded. The first preset duration is smaller than the transmission interval between the data frames. For example, when the transmission of data is performed by using a queue interval of 100ms, it is possible to confirm that one valid frame of data is received when the number of bits of the received frame exceeds half of the number of bits of the frame of data, start timing at this time, and consider that one frame of data is received after the timing exceeds 30ms, and at this time, the next frame of data is not yet transmitted, clear the received serial data bit and buffer area, and discard the frame of data, without affecting the normal reception of the next frame of data. In practical application, when detecting that the number of bits of serial data bits in the data frame received by the buffer exceeds other proportion of the number of bits of one frame of data, the buffer can confirm to receive one frame of valid data, and after estimating that one frame of data is received according to the data frame sending interval, the whole frame of data frame with two kinds of burrs is discarded.
In the control method for single-bus communication provided by the embodiment of the application, when an interference signal with duration not conforming to preset high-level duration and preset low-level duration is detected in the process of receiving serial data bits, the single-bus receiving end judges that the interference signal can be distinguished from the preset high-level signal and the preset low-level signal according to the preset level duration and the preset identification precision, if the position of the interference signal can be recorded, the serial data bits are abandoned, otherwise, after the data frame where the interference signal is located is received, the data frame is abandoned. The method and the device realize identification and classification elimination of the interference signals in the single-bus serial data frame, and avoid the influence of data dislocation caused by the interference signals on subsequent data reception, thereby realizing the effects of filtering the interference signals from the receiving end and ensuring the quality in single-bus communication.
Example two
FIG. 3 is a schematic waveform of periodic disturbances on a single bus when a pistol solenoid valve is operating at a frequency of 10 Hz; FIG. 4 is a schematic waveform of periodic disturbances on a single bus when a pistol solenoid valve is operating at a frequency of 5 Hz; FIG. 5 is a schematic waveform of periodic disturbances on a single bus when a pistol solenoid valve is operating at a 3Hz frequency; fig. 6 is a waveform diagram of a periodic disturbance waveform when there is data transmission on the bus.
In addition, during the operation of the single bus transmitting end and the single bus receiving end, the interference signal outside the normal data can be generated due to electromagnetic interference, and if the interference signal is not identified, the single bus receiving end may mistake the interference signal as the data frame. Taking external shock wave equipment as an example, single bus communication can be adopted between a host controller and a pistol controller of the external shock wave equipment so as to realize display synchronization between a host display screen and a pistol display screen, as a pistol electromagnetic valve is opened at a certain frequency, interference pulses with the same frequency can be generated, when the pistol works, communication cannot be normally carried out, if filtering processing is not carried out, a user can adjust parameters only when the pistol stops, and poor user experience is caused. As shown in fig. 3, 4 and 5, when the pistol solenoid valve operates at different frequencies, the single bus receiving end will receive the corresponding periodic interference signal, and the similar single bus receiving end will misinterpret the received data. As shown in fig. 6, when there is data transmission on a single bus, the periodic interference signal is mixed in the data frame that is normally transmitted, resulting in the data frame being received in disorder. In the single bus transmission process, when the transmission line is overlooked and subjected to external interference, such as a pistol solenoid valve operating at a certain frequency or sporadic noise interference, because the pulse is fixed or sporadic, the number and duration of the pulse are obviously different from those of a frame of data which is normally transmitted, and the fixed frequency and sporadic pulse interference are filtered out by utilizing the difference.
In contrast, based on the above embodiment, based on the single bus receiving end, the control method for single bus communication provided in 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 serial data bit received after a second preset time length;
if the number of bits of the serial data bits is less than the first threshold value, the serial data bits from the first serial data bit are cleared.
In an embodiment, the timing and the number of bits are counted from the time when the first serial data bit of a data frame is received, when the timing exceeds a certain time (for example, a quarter of the total time of normally transmitting a frame of data), according to the number of data bits received in the period, when the number of received data bits is smaller than a certain value (the number of data bits received in the period of normally transmitting a frame of data), the received data is judged to be not normal frame data, but pulse interference, so that the pulse interference is filtered out.
In practical application, normally received data of one frame will receive data bits of about 10 bits within 2ms after receiving the first serial data bit, so that when the first serial data bit of one data frame is received, the number of data bits received after timing 2ms can be detected, if the number of received bits is smaller than 4 at this time, the discontinuous interference signal of the received data bits is judged, at this time, the number of bits count is cleared, and the received data is cleared, so that the burst and periodic interference signals generated on the external single bus of normal data transmission can be filtered out.
Example III
Fig. 7 is a schematic diagram of interference waveforms coupled by one single bus line transmission on another single bus line.
On the basis of the above embodiment, if the single bus receiving end is connected to a plurality of single buses, for example, a plurality of 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 a plurality of single bus transmitting ends (for example, a host controller is connected to a plurality of pistol controllers) through a plurality of single buses, data transmitted on one single bus may couple an interference waveform on the other single bus, as shown in fig. 7. The mutual coupling interference of the transmission data among the multipath single buses cannot be filtered and judged, a filtering mechanism is not provided after the data is received, and the interference resistance is poor.
In contrast, on the basis of the above embodiment, when the single-bus receiving end is connected to a plurality of single buses, the control method for single-bus communication provided in the embodiment of the present application further includes:
when one single bus is in a receiving and transmitting state, the receiving interrupt of the other single buses is closed.
In a specific implementation, when a single bus transmitting end is to transmit data on a single bus, all external interrupts are closed, and after the IO port is configured to output, a frame of data is transmitted. The single bus receiving end carries out delay processing to prevent self-receiving and configure IO as input. The single bus receiving end and the single bus transmitting end both start the appointed external interrupt, the interrupt is started to perform mutual exclusion processing, and when one single bus transmits data, the interrupt receiving of the other single bus is ensured not to be started.
Taking the example that the single bus receiving end is connected with two single buses, when the two single buses are utilized to simultaneously transmit data, the transmission signal on one single bus can be coupled with the corresponding weak signal on the other single bus, and if the signal is not processed, the error receiving on the other single bus can be caused. When data transmission is carried out on one single bus, all external interrupts are closed, so that error data cannot be received on the other single bus; after the data transmission is completed, a designated external interrupt is started, and the interrupt reception is mutually exclusive, so that the mutual interference of the data transmitted on the two single buses is filtered.

In the first embodiment, when transmitting one frame of data, the first frame header data, the second frame header data, the address, the data, and the check bits are generally transmitted for 40 bits of data. In this regard, after interference filtering is performed on the data based on the above embodiment, the data is placed in the buffer area, and after the complete data of one frame is received, the subsequent processing is performed.
