A Distributed Control System (DCS), also called a Distributed Control System, is a new computer Control System compared to a centralized Control System. A DCS is a multi-stage computer system in the tie of a communication network, consisting of a process control stage and a process monitoring stage. Printing is an indispensable part of a DCS system and is one of key optimization objects in the practical application process of the system. The existing configuration management software can only meet some simple manual printing requirements, namely, a printing task sent by a user at a client is directly pushed to printing equipment, but in view of business diversity of printing tasks of a DCS (distributed control system), the importance degree of the printing task is different, the existing printing method cannot perform uniform scheduling management on the printing task, and when the printing equipment breaks down, the situations that the printing task cannot be processed and the printing of the important printing task is interrupted can occur, so that the normal operation of the printing function of the DCS is seriously influenced.

The embodiment provides a task scheduling method which is applied to a printing system. Fig. 2 is a flowchart of a task scheduling method according to an embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:

step S201, a task to be allocated is acquired.

Specifically, the tasks to be distributed are acquired based on a typical C/S architecture. The C/S architecture, i.e., Client-Server architecture, refers to a Server-Client architecture. The server is responsible for data management, and the client is responsible for completing interaction tasks with the user. In the present embodiment, the server is a print server, and the client includes a client-side general component. The client interacts with the print server through the client generic component. The interaction process comprises the following steps: a user designates local print data through a client, a file in EMF format is generated according to the local print data, the file is sent to a print server, and a print job is generated in the print server. The print server may adopt a redundant configuration in which a main server and one or more backup servers are provided, and when the main server fails, the service of the main server is switched to one of the backup servers, and the backup server is used as the main server. The client-side general components can be arranged in one or more computer devices to realize the interaction between a plurality of users and the client side.

Step S202, determining default equipment according to the task type of the task to be distributed, wherein the equipment type of the default equipment is suitable for the task type.

Specifically, the job to be assigned means a print job waiting to be assigned to the printer. The print jobs can be classified according to actual service types, and the print jobs are added with marks to distinguish the print jobs of different job types. Corresponding to the service type, different printers can be designated to process print jobs of the corresponding job type, that is, the printing apparatuses are classified into a plurality of apparatus types corresponding to the job type. When a print job is received, the job type of the print job is acquired, and the print job is preferentially assigned to a printer whose device type matches the job type.

Step S203, acquiring the device state of the default device.

Specifically, the device status of the default printer is detected. The device status may be a network connection status of the printer, a device operation status of the printer, or both. It is determined whether the current assignment priority is highest, i.e., whether the default printer is available. The default device may be one printing device or may refer to a plurality of printing devices of the current type.

And step S204, if the default equipment has faults, the tasks to be distributed are distributed to non-default equipment.

Specifically, when only one default printer is available, if the default printer fails and cannot complete the print job, the print job is assigned to a printer of another device type. And when a plurality of default printers exist, judging the equipment states of the current printers one by one, and if all the default printers have faults, distributing the printing tasks to the printers of other equipment types. When the print job is assigned to another type of printer, the priority of the print job of the job type when assigned to a non-default printer may be set in advance, and the job assignment may be performed in order of priority. If no printer is available, the printing server caches the printing task and informs the client that the printer needs to be replaced, so that the printing task is prevented from being lost.

Through the steps, the task scheduling method of the embodiment of the application associates the printing tasks belonging to the same service with the printers according to the service types. The printing tasks are preferentially distributed to the default printers for processing the same service, and if the default printers are detected to have faults, the printing tasks are distributed to the printers for processing other kinds of services, so that continuous printing of important printing tasks is guaranteed, and the reliability and stability of printing are improved.

In one embodiment, print jobs are sent by a client to a print server that employs a redundant configuration to improve server reliability. Specifically, a master server and one or more standby servers can be arranged to implement redundancy configuration, the standby servers can also be called slave servers, and the configuration method is master-slave configuration. Taking the setting of a main server and a standby server as an example, the master-slave identity is determined firstly, the server started firstly is the main server, the server started later is the slave server, after the master-slave identity is determined, data synchronization is performed on data between the main server and the slave server for one time, and then synchronization is performed by timing tasks at preset time intervals such as 50ms, so that the task loss caused by the fault of the print server is prevented.

In one specific embodiment, the print server configuration process includes: after the current print server is started, the working identity of the current print server is determined by comparing the current print server with another print server, and in an initialization stage, identity logic is configured inside the current print server to establish the master-slave identity of the current print server by comparing the current print server with the other print server. After the master-slave identity is determined, the working state of the master server is detected through a heartbeat mechanism. The heartbeat mechanism is a mechanism for sending a self-defined structure body or a heartbeat packet regularly to ensure the validity of the connection. Specifically, the master server sends heartbeat packets to the slave servers at regular time, and the slave servers detect the working state of the master server by receiving the heartbeat packets of the master server at regular time. Under the condition that the main server works well, the slave server rejects all the clients which are possibly connected with the slave server, and the clients select the main server to connect; and when the heartbeat between the main servers is abnormal, the slave servers are actively upgraded to the main servers to continuously work.

The slave server can be set in a hot standby mode and a cold standby mode. The hot standby means that the slave server and the main server operate together, and when the main server fails or stops, the slave server immediately takes the working task of the failed equipment; the cold standby means that after the main server fails or stops, the slave server starts to enter a starting operation state from a stop waiting state and takes the work task of the failed equipment. Preferably, in order to save energy and avoid unnecessary cost loss, the server is configured in a cold standby mode in the embodiment. The slave server can synchronize the printing data of the master server at regular time, but the slave server does not distribute printing tasks and does not accept the connection request of the client, when the slave server detects the heartbeat abnormality of the master server, the slave server can be automatically upgraded to the master server and informs the client to carry out connection switching, and the client is connected with the slave server. When the main server fails, the printing equipment and the slave server are connected in advance, so that the printing equipment and the slave server do not need to be accessed again, and the slave server is upgraded to the main server to execute a printing task.

In one embodiment, if the network communication between the print service and the printing device is abnormal, the print server detects the abnormality and reports the abnormality, and then the manual switching server can be executed through the operation of the client interface, the standby print server is upgraded to the main print server, and the original main print server is downgraded to the standby print server. It is emphasized that the network between the print server and the printing apparatus does not require a redundant setting, and the network between the master and slave print servers requires a redundant setting.

Specifically, when the server receives print files sent by a plurality of clients in the same time period, the print server performs priority ordering according to the task types of the print tasks, for example, when a full-log print task, an event record print task, and a document print task exist, the full-log print task, the event record print task, and the document print task are also set in order from high to low in priority according to business importance. And in a preset time period, when the three types of tasks need to be distributed, preferentially distributing the printing tasks of the task type of full log printing, and then sequentially distributing the event recording tasks and the document printing tasks. The task type and corresponding priority of the printing task can be adjusted according to actual business requirements.

Specifically, in this embodiment, the print jobs are divided into three types, i.e., full log print jobs, event record print jobs, and office document print jobs, according to actual business needs. The full log print job refers to: and printing log data in the operation process of the DCS. The log printing generally includes four levels of log data, which are ERROR, WRAN, INFO, DEBUG from high to low, and the so-called full log printing is to print all the four levels of log data. The ERROR log means that ERRORs at this level need to be processed immediately, and when an ERROR occurs, normal access of a user is affected, and the ERROR needs to be processed by an administrator immediately. The WARN log refers to: for the WARN level logs, attention needs to be paid, although it is not required for the administrator to immediately handle them. The WARN log includes two cases: one is that there are significant problems with the solution and the other is the potential problem and suggestion. Applications can tolerate this information, but the information should be checked and repaired in a timely manner. Dangerous operations of some users, such as actions of always adopting wrong passwords to try to log in an administrator account, can also be promoted to the WARN log level for recording. The INFO log is mainly used for recording information such as system running state and user operation behavior. This level log is often used to feed back the current state of the system to the end user. And the DEBUG log has the main function of accurately recording the running state of each step of the system. Through the log, the execution process of each step of certain operation can be checked, and the operation, the parameter and the sequence of the operation can be accurately positioned to cause certain errors. The method can ensure that the problems can be diagnosed through the log record of the DEBUG level under the condition that no error occurs. The information of the log printing generally comprises time, process, thread, level, module, Filter, operator, participation, content and the like. The event records the type of print job, i.e., SOE print job. The SOE, all called Sequence OF Event, refers to Event Sequence logging, and records the time OF occurrence OF a fault and the type OF Event. In most important industrial fields such as main machines of power plants, paper making and the like, once shutdown and parking occur in the process of system joint debugging or production operation, accident reasons need to be searched through a DCS platform, the technical processes of the items are complex and high in real-time performance, general alarm records and historical trends cannot be used for accurate accident analysis, and therefore event sequence records are called as necessary functions of the DCS. The office document printing task refers to a common document printing task generated in the daily office process. Correspondingly, the types of printing devices are classified into three types according to the types of print jobs they handle, namely, log printers, event record printers, and document printers.

FIG. 3 is a schematic diagram of a print service deployment according to an embodiment of the present application, including a primary print server and a backup print server connected to a plurality of clients via a network, as shown in FIG. 3. The main printer server and the standby print server are connected to a plurality of types of printers via a network. Fig. 4 is a task scheduling diagram of a task scheduling method according to an embodiment of the present application, and as shown in fig. 4, a client sends a print request to a scheduling thread of a server, and the scheduling thread sends a print task to different task queues according to task types and task priorities according to states of respective printer devices detected by a detection thread, and further sends the print task to a corresponding printer for printing.

Specifically, the monitoring of the printer judges whether the printer network is normal or not by sending ping network data packets to the printer in a timed and simulated manner. Ping, Ping Packet Internet Groper, is an intel Packet explorer for a program to test network connection volume. Ping is a service command working in the application layer of the TCP/IP network architecture, and mainly sends an ICMP (Internet Control Message Protocol) Echo request Message to a specific destination host, and tests whether the destination station can reach and know the relevant status. Ping is used for determining whether the local host can successfully exchange data packets with another host, and then whether the TCP/IP parameters are correctly set, whether the operation is normal, whether the network is smooth and the like can be inferred according to the returned information.

Specifically, the device operating state of the printer is acquired through an operating system interface. Equipment operational failures include, but are not limited to, paper out, ink out, paper jam, print queue fullness, etc. The equipment fault common to the printer can be set with an identification code, and when the fault identification code of the printer is received, the current equipment is not available.

Specifically, when detecting that the current default printer has a fault, detecting whether other printers of the same equipment type are available, and if all the printers of the same type of the default printer have the fault, distributing the printing tasks to the other types of printers in consideration of avoiding interruption of printing of important printing tasks. When a print job is assigned to a non-default device, printers are classified in advance according to print services, and priorities are determined for each type of printing, that is, the devices are assigned with priorities. For example: the printing tasks comprise full log printing tasks, event record printing tasks and office document printing tasks; printers include journal printers, event log printers, and document printers. When the tasks are distributed, the printing tasks are firstly sorted according to the task priority, and the sorted task distribution sequence is as follows: full log print jobs, event log print jobs, and office document print jobs. And then performing task allocation one by one, allocating a full log printing task first, acquiring the equipment state of the full log printer at this time, if the full log printer is available, allocating the full log printing task to the full log printer, and if the full log printer has a fault, acquiring the equipment allocation priority of the full log printing task. And after the full log print job is distributed, distributing the event record print job. And the event record printing task is preferentially distributed to the event record printer, and if the event record printer fails, the event record printing task is distributed to the document printer. If the document printer is in fault at the moment, the situation that no printer is available is indicated, the printing task is cached at the moment, printer fault alarm is carried out at the client side, the client is informed that the printer needs to be replaced, and the printing task is prevented from being lost.

Through the steps, the printing tasks and the printers are classified and the priority order is established according to the business requirements. Under the condition that the printing system operates normally, different types of printing tasks are distributed to corresponding task queues by the task distribution threads, and when a printer fault occurs, the printer can be preempted according to the task priority. For example: when the full log printer fails, preempting the printer with the lowest priority, namely the document printer according to the preemption rule, suppressing the document printing task, and preempting the SOE event sequence recording printer if the document printer fails again. A difficulty with existing print job scheduling management is that each type of print job is assigned an appropriate printer. According to the method and the device, the printer is defined as the global resource, the default task type, the execution task type and the printer state attribute are defined, and then management is carried out by the scheduling thread, so that the task scheduling efficiency and accuracy are improved, and the stable execution of important printing tasks is guaranteed. It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
