Description
TECHNICAL FIELD
[0001] The present application relates to a sequence of event recording processing method, device, equipment, medium and program product, and belongs to the field of industrial process control. BACKGROUND
[0002] In the field of industrial process control, the controller communicates with the board card below and the host computer above. The controller needs to monitor some important on-off signals in real time. When these on-off signals change position, the controller will first receive the signal channel number, current state value and position change time and other information sent by the board card, add auxiliary information related to the signal, form a sequence of event (SOE, Sequence Of Event), and send it to the host computer, so that when the field device fails, the host computer can know the accurate sequence and time of the related event, which is crucial for fault diagnosis and system analysis. Generally speaking, in order to enable the host computer to obtain as comprehensive information as possible, the sequence of event sent by the controller will add information such as textual description of the signal, KKS code, recording level, recording type, etc. The controller usually uses a single buffer area to process the sequence of event, that is, the controller receives the information sent by the board card, forms the sequence of event, and then stores it in the buffer area. When the subsequent sequence of event needs to be sent to the host computer, the sequence of event is extracted from the buffer area. Some controllers, in order to ensure the timeliness of processing, only contain a small amount of information in the sequence of event, which is not conducive to the fault diagnosis and system analysis of the host computer. Some controllers, in order to facilitate diagnosis, contain a wealth of information in the sequence of event, but when the field device fails seriously, a large number of on-off signals change position in a short period of time, and then a large amount of information of the sequence of event is generated and needs to be sent to the host computer. In the face of such a situation of instantaneous large amount of information of the sequence of event, the controller not only has difficulty in processing all the information in time, resulting in the loss of part of the sequence of event and the inability to ensure the integrity of the record, but also occupies a large amount of system resources due to the sharp increase in processing load, thereby interfering with the normal control task of the controller and seriously affecting the stable operation of the industrial process and the accuracy of fault diagnosis.

[0021] The embodiment has the advantages that Figure 1 As shown in the figure, the first buffer area is used to store key information, and the second buffer area is used to supplement extended information, which can meet the specific needs of the upper computer for event processing priority query, and can also expand to meet the additional information needs of the upper computer. The cooperative work of the double buffer areas effectively balances the efficiency and comprehensiveness of information processing, and provides strong support for the efficient operation of the upper computer.
[0022] In some possible embodiments, the board card communicates with the processor through a communication interface, the board card comprises a switching value input board card or a switching value output board card, and the board card communicates with the processor to output displacement information to the processor; The displacement information comprises a signal channel number, a current state value and a displacement time.

[0023] In some possible embodiments, the first cache area and the second cache area both adopt a circular queue form to store the event sequence records. The first cache area in this embodiment adopts a circular queue to implement one queue element corresponding to one first event sequence record, and the upper limit of the first event sequence records that can be cached can be set and adjusted according to actual conditions. When the queue is full, the new record is directly discarded without covering the old record, which is used to ensure the integrity of the previous record. Under the same condition, the second cache area also adopts a circular queue to implement one queue element corresponding to one first event sequence record, and the upper limit of the second event sequence records that can be cached can be set and adjusted according to actual conditions. When the queue is full, the new record is directly discarded without covering the old record, which is used to ensure the integrity of the previous record.
[0024] In some possible embodiments, the upper limit of the storage capacity of the second cache area is higher than the upper limit of the storage capacity of the first cache area. The number of the first event sequence records extracted from the first cache area each time in this embodiment can be set and adjusted according to actual conditions. Similarly, the number of the second event sequence records extracted from the second cache area each time can also be set and adjusted according to actual conditions.
[0025] In some possible embodiments, the host computer software includes at least one of or any combination of analysis software and monitoring software, and can perform fault diagnosis and system analysis through the second event sequence records and the extended information distributed by the second cache area.

[0027] In some possible embodiments, the acquisition module, the extension module and the sending module are independently executed in threads of three different priorities, respectively, wherein the execution priority of the acquisition module is higher than that of the extension module, and the execution priority of the extension module is higher than that of the sending module. Specifically, there may be a case that a step with a higher priority is continuously executed for multiple times, and other steps cannot be executed during this period. Specifically, assuming that the acquisition module still receives new displacement information sent by the board after completing a task, the task will be executed again, instead of the task of the extension module. Therefore, the application can ensure that more critical information is processed preferentially. Embodiments
