The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations (or steps) can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The technical scheme of the application obtains, stores, uses and processes the data and the like all conform to the relevant regulations of national laws and regulations.
Fig. 1 is a flowchart of a multi-serial port synchronous processing method provided in an embodiment of the present application, where the embodiment is applicable to a case of synchronous processing of synchronous services acquired by a multi-serial port bus, the method of the present embodiment may be performed by a multi-serial port synchronous processing device, and the device may be implemented by using hardware and/or software. The device can be configured in a server for synchronous processing of multiple serial services. The method specifically comprises the following steps:
s110, acquiring at least two to-be-processed services, and determining the service types of the at least two to-be-processed services.
Referring to fig. 2, different serial devices are connected under different serial ports of the industrial gateway, and part of services in the devices need to be used for synchronization service. For example, device 1 and device 2 need to be on-line or off-line simultaneously, and the time difference between on-line and off-line cannot be greater than 50ms; if the requirement cannot be met by conventional design, a synchronous control mechanism for different devices is introduced at the moment, so that the embodiment of the application provides a multi-serial data synchronous processing method.
The method comprises the steps of acquiring at least two to-be-processed services and determining service types, wherein the service types of the to-be-processed services comprise real-time services, timing services and synchronous services. Wherein, the real-time service refers to a service capable of providing timely response under strict time limitation; real-time services need to be completed within a predetermined time and reliability and accuracy of response time need to be ensured. Timing services refer to services that are performed according to a predetermined schedule or plan; the timing service may be triggered and executed according to a predetermined point in time or time interval to meet a particular demand; timing services are typically used for periodic tasks, timing reminders, timing data collection, and the like. The synchronous service refers to a process of transmitting and processing data among a plurality of devices or modules according to a preset time sequence; in a synchronous service, devices or modules maintain synchronous transmission and processing of data by sharing clock signals, using specific data frame formats, flow control mechanisms, state synchronization, or the like. Synchronization services are often used in scenarios where data consistency and timing needs to be maintained, such as multi-device collaboration and data synchronization.
S120, storing the at least two services to be processed in a preset service cache queue, and traversing the preset service cache queue to determine whether a synchronous service sequence exists.
Referring to fig. 3, after the at least two to-be-processed services are obtained, the at least two to-be-processed services are stored in a preset service cache queue, the preset service cache queue is processed, and whether a synchronous service sequence exists in the preset service cache queue is determined.
The synchronization service sequence refers to a sequence formed by a plurality of synchronization services according to a certain sequence. In the sequence of synchronous services, each synchronous service has a specific execution time and execution sequence, and the execution time of the previous synchronous service affects the execution time of the subsequent synchronous service. In the embodiment of the application, the synchronous service sequence is used for representing synchronous service among different devices connected by different serial ports; for example, if the serial port 1 is connected to the device 1 and the serial port 2 is connected to the device 2, and the device 1 and the device 2 are required to process simultaneously in a specific service, the service sequence between the serial port 1 and the serial port 2 is a synchronous service sequence.
As an optional but non-limiting implementation manner, the storing the at least two pending services in a preset service cache queue includes steps A1-A2:
step A1: and determining the service types of the at least two to-be-processed services and determining serial numbers of the at least two to-be-processed services.
Step A2: and packaging the at least two to-be-processed services, and storing the packaged at least two to-be-processed services in a preset service cache queue.
And at least two synchronous services belonging to the same synchronous service sequence are endowed with the same identity code for encapsulation.
The at least two to-be-processed services also need to be packaged before being stored in a preset service cache service. Service frame structure referring to fig. 4, the first byte "TYPE" represents a service TYPE; wherein, 1 characterizes real-time service, 2 characterizes timing service, and 3 characterizes synchronous service. The second byte "syn_sn" represents the serial number, representing the current service serial number. The third and fourth byte SYN_SN_TOTAL represent the target serial number of the synchronous service, and only the synchronous service is valid; if the current service is a timing service or a real-time service, the third and fourth bytes are empty. The fifth and sixth byte "syn_id" is a synchronous service random ID, and the same synchronous service is the same ID and unique.
In an alternative scheme of the embodiment of the application, the service frame structure is analyzed in the synchronous service processing module, and the first byte in the service frame structure is analyzed to obtain the specific service type of the frame, so as to determine whether the frame is a synchronous service frame; analyzing the second byte to obtain a serial number corresponding to the synchronous service frame, traversing a preset service buffer queue, and obtaining whether the batch of synchronous service requests are in place or not; analyzing the third byte and the fourth byte of the synchronous frame in the buffer queue to obtain serial port equipment serial numbers and target serial port serial numbers related to the synchronous service; and analyzing the fifth byte and the sixth byte of the synchronous service frame to obtain a service frame ID, and brushing and selecting the synchronous service frame of the same sequence.
As an optional but non-limiting implementation manner, the storing the at least two services to be processed in a preset service buffer queue, and traversing the preset service buffer queue to determine whether a synchronous service sequence exists, includes steps B1-B2:
step B1: and constructing a preset service cache queue, and storing the at least two services to be processed into the preset service cache queue according to the receiving sequence.
Step B2: traversing at least two to-be-processed services in the preset service cache queue, and determining whether a synchronous service sequence exists in the preset service cache queue.
A preset service cache queue is constructed and used for storing the service to be processed; adding the received at least two services to be processed into a preset service cache queue according to the receiving sequence; traversing the preset service cache queue, and determining whether synchronous service exists in the preset service cache queue according to a specific value of a first byte in a service frame structure; if it is determined that there is one synchronization service, the preset service cache queue may be continuously traversed to find a possible synchronization service sequence.
As an optional but non-limiting implementation manner, the traversing at least two services to be processed in the preset service cache queue, determining whether a synchronous service sequence exists in the preset service cache queue, includes steps C1-C2:
step C1: if the first synchronous service exists in the preset service cache queue, determining whether a second synchronous service exists in the preset service cache queue; the second synchronization service and the first synchronization service belong to the same synchronization service sequence.
Step C2: if the second synchronous service exists in the preset service cache queue, determining that the synchronous service sequence exists in the preset service cache queue.
Traversing the preset service cache queue, and determining whether a first synchronous service and a second synchronous service exist in the preset service cache queue; the first synchronization service and the second synchronization service belong to the same synchronization service sequence. If the first synchronous service and the second synchronous service exist in the preset service cache queue, a synchronous service sequence exists in the preset service cache queue. In the embodiment of the application, all synchronous services in the same synchronous service sequence are called synchronous service in-place in a preset service cache queue. Determining a target number of synchronous services included in the synchronous service sequence according to the number of target serial numbers representing synchronous services in a third four byte of the service frame structure; traversing a preset service cache queue, and determining whether the number of synchronous services in the preset service cache queue is a target number; and if the number of the synchronous services obtained through traversing is the target number, determining that the synchronous service sequence is in place. For example, determining that the first synchronization service sequence includes 3 synchronization services according to the number of the target serial numbers representing the synchronization services in the third four bytes of the service frame structure; the first synchronization service sequence comprises a first synchronization service, a second synchronization service and a third synchronization service; if a first synchronous service, a second synchronous service and a third synchronous service exist in a preset service cache queue, the first synchronous service sequence is in place; and after the first synchronization service sequence is in place, carrying out synchronization processing on the first synchronization service, the second synchronization service and the third synchronization service.
As an optional but non-limiting implementation manner, the traversing at least two services to be processed in the preset service buffer queue, determining whether a synchronous service sequence exists in the preset service buffer queue, further includes steps D1-D2:
step D1: if the first synchronous service exists in the preset service cache queue, but the second synchronous service does not exist in the preset service cache queue, determining that the synchronous service sequence in the preset service cache queue is not in place.
In an alternative scheme of the embodiment of the present application, if all the synchronization services belonging to the same synchronization service sequence are not cached in the same preset service cache queue, the synchronization service sequence in the preset service cache queue is not located. For example, determining that the second synchronization service sequence includes 2 synchronization services according to the number of the target serial numbers representing the synchronization services in the third four bytes of the service frame structure; the second synchronous service sequence comprises a first synchronous service and a second synchronous service; if the preset service cache queue is traversed, determining that the first synchronous service exists in the preset service cache queue, but the second synchronous service does not exist in the preset service cache queue, and if the synchronous service sequence in the preset service cache queue is not in place.
Step D2: or if at least two services to be processed in the preset service cache queue are traversed, determining that a first synchronous service does not exist in the preset service cache queue, and determining that a synchronous service sequence does not exist in the preset service cache queue.
In an alternative scheme of the embodiment of the present application, when traversing the preset service cache queue, if no synchronization service exists in the preset service cache queue, it is determined that no synchronization service sequence exists in the preset service cache queue.
S130, if the synchronization service sequence exists in the preset service cache queue, performing synchronization processing on the synchronization service sequence.
In which, referring to fig. 5, the existing service processing is generally that all services are processed in sequence, and only one service can be processed at the same time. For example, there are n services in one network management, and the n services are serially processed from service 1 to service n in a preset order. Serial processing cannot meet the requirement that part of the services need to be processed synchronously, so in the embodiment of the application, a processing scheme as shown in fig. 6 is provided. If the synchronization service sequence (e.g. service 2) exists in the preset service buffer queue, the service 2 is preferentially sent to the designated serial device at the same time, and the synchronization service processing is performed first.
As an optional but non-limiting implementation manner, if the synchronization service sequence exists in the preset service buffer queue, the synchronization service sequence is processed synchronously, and the method further includes but is not limited to steps E1-E2:
step E1: and if the synchronous service sequence exists in the preset service cache queue, suspending the executing timing service.
Step E2: and taking out the synchronous service from the preset service cache queue according to the receiving sequence and carrying out synchronous service processing.
In an alternative scheme of the embodiment of the present application, if a synchronization service sequence exists in the preset service buffer queue, the timing service being executed is suspended; and taking out the synchronous service from the preset service cache queue according to the receiving sequence and carrying out synchronous service processing. For example, a first service to be processed is taken out from the preset service cache queue to be a timing service, and a second service to be processed is taken out to be a synchronous service; at this time, the timing service being executed is suspended, other synchronous services belonging to the same synchronous service sequence with the synchronous service are taken out from a preset service cache queue, and the serial port transceiver module is triggered to carry out synchronous processing on the synchronous service in the synchronous service sequence; and recovering the timing processing of the timing service after the synchronization processing of the synchronization service is completed.
As an alternative but non-limiting implementation, after determining that the synchronization service sequence in the preset service buffer queue is not in place or that the synchronization service sequence is not present in the preset service buffer queue, the method includes, but is not limited to, steps F1-F2:
step F1: and if the synchronous service sequence in the preset service cache queue is not in place or the synchronous service sequence does not exist in the preset service cache queue, taking out the target service to be processed from the preset service cache queue according to the receiving sequence.
Step F2: determining the service type of a target to-be-processed service, and determining different service processing modes according to the service type of the target to-be-processed service; the target pending service includes a timing service and a real-time service.
The method comprises the steps that a synchronous service sequence in a preset service cache queue is not located, or the synchronous service sequence does not exist in the preset service cache queue, and then target to-be-processed services are sequentially taken out from the preset service cache queue; and processing according to the service type of the target service to be processed. For example, if the synchronization service sequence is not in place or does not exist in the preset service cache queue, sequentially taking out the target to-be-processed service to be processed; and if the taken target to-be-processed service is the timing service, delivering the timing service to a timer module to finish timing processing of the timing triggering serial port receiving and transmitting module. If the taken target service to be processed is real-time service, the serial port receiving and transmitting module is directly triggered to complete real-time processing.
The multi-serial port synchronous processing method provided by the embodiment of the application comprises the steps of obtaining at least two to-be-processed services and determining the service types of the at least two to-be-processed services; the service type of the service to be processed comprises real-time service, timing service and synchronous service; storing the at least two services to be processed in a preset service cache queue, and traversing the preset service cache queue to determine whether a synchronous service sequence exists or not; the synchronous service sequence is used for representing synchronous service among different devices connected by different serial ports; and if the synchronization service sequence exists in the preset service cache queue, carrying out synchronization processing on the synchronization service sequence. By adopting the technical scheme of the embodiment of the application, the service to be processed is classified and stored in a preset service cache queue; traversing a preset service cache queue to determine synchronous service, and setting a corresponding identity code for the synchronous service; the synchronous service of the same identity code is processed preferentially, so that the problem that different services of the multi-serial device cannot be processed synchronously is solved.
