In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1, in an embodiment of the present invention, a circular queue-based SOE data uploading method is provided to implement reliable SOE data uploading, and specifically, the circular queue-based SOE data uploading method includes the following steps.
S1: and obtaining SOE data of each channel which is turned in the board card, sequencing the SOE data of each channel which is turned according to the turning time sequence of each channel, and sequentially inserting the SOE data into a preset circular queue. The board card is a digital output card or a digital input card. The method for acquiring SOE data of each channel which is overturned in the board card comprises the following steps: acquiring a channel value of a current channel in a current sampling period and a channel value of a previous sampling period, and turning over the current channel when the channel value of the current channel in the current sampling period is inconsistent with the channel value in the previous sampling period; and recording the channel value of the current channel and the time of the turning according to a preset structure body to obtain the SOE data of the current channel.
Referring to fig. 2, the name of the preset structure is SOE _ VALUE, and the preset structure includes five parameters that are sequentially set, which are sequentially: ID. value, utc _ s, fraction _ s, and utc _10 us; wherein, the ID represents the channel number of the current channel; value represents the channel value of the current channel; utc _ s represents the seconds value of the time when the current channel flips; frac _ s represents the millisecond value of the time that the current channel flips; utc — 10us represents a 0.01 millisecond value of the time at which the current lane rollover occurred.
Because the traversal order is not necessarily the order of the events of the upset events of the channels which are overturned, in order to ensure that the upset events of different channels can also be sent to the controller according to the time order, the obtained array soe _ array is sorted from first to last according to the time of each element, because one sampling period is usually less than 1ms, the overturning time of each channel in the same sampling period is only utc _10us inconsistent, and the sorting only needs to be carried out according to the size of utc _10 us.
Specifically, the specific method for sorting the reversed SOE data of each channel according to the reversed time sequence of each channel includes: inserting SOE data of each channel with the current sampling period being reversed into a preset array corresponding to the current sampling period; traversing each array, obtaining utc _10us values of SOE data in the current array, and arranging the SOE data in the current array according to the descending order of the utc _10us values; and sequencing the arrays corresponding to the sampling periods according to the time sequence of the sampling periods.
Preferably, during initialization, a null array SOE _ array consistent with the number of channels of the board digital quantity is pre-constructed and used for storing the SOE data of each channel which is inverted in the same sampling period, the number of the SOE data which can be contained in the array is consistent with the number of channels of the board, and the corresponding relation is that one SOE _ VALUE object corresponds to one array element.
Preferably, during initialization, a circular queue SOE _ queue with a number greater than that of channels is constructed, the circular queue is used for storing channel SOE data with numerical VALUE inversion in different sampling periods, an SOE _ VALUE object corresponds to a queue element, the number of SOE data that can be accommodated in the circular queue is usually K times of the number of channels of the board, and the number of SOE data that can be accommodated in the circular queue can be adjusted according to actual conditions, generally the number of execution times of a sampling period in an uploading period.
Referring to FIG. 3, SOE data in the sorted array is inserted into the circular queue SOE _ queue in order.
S2: and acquiring the state of the circular queue, and adding an SOE mark into a periodic data message sent to the controller when the state of the circular queue is not empty.
And acquiring the state of the circular queue, and when the circular queue is not empty, adding an SOE mark in a periodic data message replied to the controller by the board card to inform the controller that an aperiodic SOE inquiry message can be sent to the board card. And after the controller receives the periodic data message replied by the board card, unpacking to find the SOE mark, and indicating that the board card has SOE data to wait for uploading.
S3: receiving and responding to an SOE inquiry message sent by a controller, and carrying out an uploading step; wherein, the uploading step: and sequentially encoding SOE data in the circular queue into an SOE uploading message according to the insertion sequence, and transmitting the SOE uploading message to the controller.
The board card receives an SOE inquiry message sent to the board card by the controller, responds to the SOE inquiry message, and performs the uploading step: and sequentially encoding SOE data in the circular queue into an SOE uploading message according to the insertion sequence, and transmitting the SOE uploading message to the controller. Specifically, the SOE data in the circular queue SOE _ queue are sequentially dequeued, and the dequeued SOE data are sequentially encoded in an SOE report and then transmitted to the controller.
S4: receiving and analyzing a periodic data query message sent by a controller to obtain an analysis result; when the SOE confirmation mark exists in the analysis result, the uploading is completed; otherwise, backing back the SOE data which is uploaded in the circular queue, and performing the uploading step again.
Specifically, after the controller receives the SOE data sent by the board card, an SOE confirmation flag is inserted into the periodic data query message. And the board card analyzes the received periodic data query message to obtain an analysis result, and if an SOE confirmation mark is found in the analysis result, the board card confirms that a round of SOE data uploading process is completed. If the analysis result does not find the SOE confirmation mark, the SOE data loss occurs, the rollback operation is carried out on the circular queue, the SOE data uploaded in the circular queue is rolled back, and the uploading step is carried out again.
Preferably, the step of sending up further comprises: acquiring an updated queue head pointer and an initial queue head pointer; moving an updated queue head pointer by one bit along the direction from the head of the circular queue to the tail of the circular queue until all SOE data in the circular queue are encoded into the SOE upload message; the specific method for backing back the SOE data uploaded in the circular queue comprises the following steps: the current updated queue head pointer is replaced with the initial queue head pointer.
Specifically, the head pointer is defined during initialization, and the SOE data in the circular queue SOE _ queue are dequeued in sequence, and the head pointer moves to the tail of the queue once every SOE data is dequeued. Meanwhile, in order to realize dequeue operation rollback, dequeue operation does not directly delete elements in the circular queue, only the head pointer is moved, in addition, a global variable old _ head is also defined during initialization and is used for recording the position to which the head pointer initially points, SOE data rollback operation on the board card needs to be realized through the old _ head pointer of the circular buffer, and when rollback is needed, the head pointer of the circular queue is redirected to the position to which the old _ head points.
The SOE data uploading method based on circular queue includes that the step S1 can be performed in a sampling period, and the steps S2 to S4 can be performed in a communication period.
In summary, the SOE data uploading method based on circular queues of the present invention can achieve sequentiality and high reliability.
Wherein, the sequence: SOE data of each channel which is inverted in a single sampling period are sequenced according to inversion time in the sampling period, and the SOE data are inserted into a circular queue in sequence after sequencing is completed. Because different sampling periods are in sequence, the minimum inversion time of the SOE data in the next sampling period is certainly longer than the maximum inversion time of the SOE data in the previous sampling period. Therefore, when SOE data in a plurality of sampling periods are present in the circular queue, the SOE data must be sorted in time order. Because the circular queue has the characteristic of first-in first-out, SOE data with small turnover time can be received and processed by the controller earlier when the SOE is sent to the controller.
High reliability: the high reliability means that the controller can not receive the SOE data recorded by the board, and if the SOE data exist and are not received by the controller, the board can repeatedly upload the SOE data to the controller. After receiving the SOE data uploaded by the board card, the controller in the communication period sends an SOE confirmation mark to the board card, and the board card knows that the controller has received the uploaded SOE data after receiving the SOE confirmation mark. If the controller does not send the SOE confirmation mark to the board card, the board card can carry out SOE data rollback operation and informs the controller that the SOE data exists in the board card and the controller needs to send an SOE inquiry message, so that the SOE data can be sent to the controller again until the controller completely receives the SOE data.
