According to the technical scheme, the frequent seek operation of the disk for many times caused by a multi-process/multi-thread processing mode can be effectively avoided when the data processing speed is slightly less than the read-write average value of the disk, so that the disk throughput is guaranteed, the system processing speed is increased, and the system processing capacity is improved.
Fig. 1 shows a flowchart of a data processing method according to an embodiment of the present disclosure, which includes the following steps S101 to S103, as shown in fig. 1:

in step S103, in response to detecting the end of data transfer, the connection with the disk is cut off or data transfer end information is sent to the controller.
As mentioned above, with the development of data technology, in order to increase the system data processing speed and improve the system data processing capability, almost all operating systems adopt a multi-process/multi-thread processing mode when processing data, especially when processing a large number of data files. However, under the condition of using the mechanical hard disk, when the data processing speed is slightly less than the read-write average value of the disk, the multi-process/multi-thread processing mode will cause multiple frequent seek operations of the disk, thereby reducing the throughput of the disk and further reducing the processing speed of the whole system.
In view of the above, in this embodiment, a data processing method is proposed which realizes read/write management for a disk by performing open/close control of data transfer for an object such as a program which executes data transfer. According to the technical scheme, the phenomenon that the disk is repeatedly tracked due to a multi-process/multi-thread processing mode when the data processing speed is slightly smaller than the read-write average value of the disk can be effectively avoided, so that the disk throughput is guaranteed, the system processing speed is increased, and the system processing capacity is improved.
In an embodiment of the present disclosure, the data processing method may be applied to an object that needs to establish a connection with a disk to perform data transmission, such as a certain program, and the like, of a computer, an electronic device, a server, and the like that can perform data processing.
In an embodiment of the present disclosure, the data transmission instruction refers to an instruction for instructing data transmission, and the data transmission instruction may be issued by a user or by another execution subject.

In an embodiment of the present disclosure, the data transmission end information is information used to indicate that the data transmission is completed this time, and after receiving the data transmission end information, the controller may cut off the connection between the data transmission object and the disk.
In the above embodiment, if the data transfer object receives a data transfer instruction sent by a user or another execution main body, which indicates that there is a need to connect to a disk for data transfer at this time, a disk connection request is sent to the controller; if the disk connection confirmation information sent by the controller is received, which indicates that the disk can be connected by confirmation at the moment, establishing connection with the disk, and executing data transmission; after the data transmission is detected to be finished, the connection between the data transmission object and the disk can be cut off or data transmission finishing information is sent to the controller, so that the controller cuts off the connection between the data transmission object and the disk, and the disk connection resources are released in time, so that other data transmission objects can sequentially and effectively use the disk, multiple frequent seek operations of the disk are avoided, the throughput of the disk is guaranteed, the system processing speed is improved, and the system processing capacity is improved.
In an embodiment of the present disclosure, the method further comprises the steps of:
and setting a data cache space.
In order to save the disk occupation time and improve the effectiveness of disk connection, in this embodiment, a data cache space is further provided to cache the acquired data, wherein the capacity of the data cache space should be greater than a preset capacity threshold, that is, the data cache space should be set as large as possible, so as to effectively apply the storage requirement of the cached data. The data cache space may be implemented based on a temporary file system, for example, more temporary file spaces may be requested according to the needs of the actual application; the method can also be implemented based on the SWAP partition, the SWAP partition technology is to release a part of the space in the hard disk memory for the currently running programs when the physical memory of the system is not enough, the released space may come from some programs which do not have any operation for a long time, the released space is temporarily stored in the SWAP partition, and the stored data is restored from the SWAP partition to the memory when the programs are to run.
In this embodiment, the step S102, namely, in response to receiving the disk connection confirmation information sent by the controller, establishing a connection with the disk, and performing data transmission, may be implemented as:
and responding to the received disk connection confirmation information sent by the controller, establishing connection with the disk to read data, and storing the read data in the data cache space.
The step S103, namely, the step of disconnecting the connection with the disk or sending data transmission end information to the controller in response to detecting the end of data transmission, may be implemented as:
and in response to detecting the end of data reading, cutting off the connection with the disk or sending data reading end information to the controller.
In the above embodiment, after receiving the disk connection confirmation information sent by the controller and establishing the connection with the disk, the read data is stored in the data cache space, and after detecting that the data reading is finished, the connection with the disk is cut off or data reading end information is sent to the controller, so that the controller cuts off the connection between the data transmission object and the disk, and the disk connection resource is released in time, so that other data transmission objects can sequentially and effectively use the disk. And then, offline data processing can be performed under the condition that disk resources are not occupied, connection with the disk is requested after the offline data processing is finished, and the processed data is transmitted to the disk.

and in response to detecting the end of data writing, cutting off the connection with the disk or sending data transmission end information to the controller.
As mentioned above, after the connection with the disk is established, the read data is stored in the data cache space, and then the connection with the disk is cut off or data reading end information is sent to the controller, so that offline data processing can be performed without occupying disk resources, the validity of disk connection is improved, and subsequently, the connection with the disk can be requested after the offline data processing is finished, and the processed data is transmitted to the disk. Therefore, in this embodiment, after the data reading is finished, the read data stored in the data cache space is processed, after the data processing is finished, a disk connection request is sent to the controller, after the disk connection confirmation information sent by the controller is received, the connection with the disk is re-established, the processed data is written into the disk, and after the data writing is finished, the connection with the disk is cut off or data transmission end information is sent to the controller, so that the controller cuts off the connection between the data transmission object and the disk, and the disk connection resource is released in time, so that other data transmission objects can sequentially and effectively use the disk.
Fig. 2 shows a flowchart of a data processing method according to another embodiment of the present disclosure, which includes the following steps S201 to S203, as shown in fig. 2:
in step S201, in response to detecting a disk connection request issued by a target object, determining whether a disk is in an available state;
in step S202, when it is determined that the disk is in an available state, confirming connection between the target object and the disk, and sending disk connection confirmation information to the target object;
in step S203, in response to detecting that the target object establishes a connection with the disk, the disk is set to an unavailable state.
As mentioned above, with the development of data technology, in order to increase the system data processing speed and improve the system data processing capability, almost all operating systems adopt a multi-process/multi-thread processing mode when processing data, especially when processing a large number of data files. However, under the condition of using the mechanical hard disk, when the data processing speed is slightly less than the read-write average value of the disk, the multi-process/multi-thread processing mode will cause multiple frequent seek operations of the disk, thereby reducing the throughput of the disk and further reducing the processing speed of the whole system.
In view of the above, in this embodiment, a data processing method is proposed which realizes read/write management for a disk by performing open/close control of data transfer for an object such as a program which executes data transfer. According to the technical scheme, the phenomenon that the disk is repeatedly tracked due to a multi-process/multi-thread processing mode when the data processing speed is slightly smaller than the read-write average value of the disk can be effectively avoided, so that the disk throughput is guaranteed, the system processing speed is increased, and the system processing capacity is improved.
In an embodiment of the present disclosure, the data processing method may be applied to a disk management side, such as a controller, etc., of a computer, an electronic device, a server, etc., which may perform data processing.
In an embodiment of the present disclosure, the target object refers to an object, such as a program, that wants to establish a connection with a disk for data transmission.
In an embodiment of the present disclosure, to avoid multiple frequent seek operations of a disk caused by a multiprocess/multithread processing manner, throughput of the disk is guaranteed, system processing speed is increased, and system processing capacity is improved, where a state of the disk is set to be available or unavailable according to whether a data connection has been established with the disk, for example, if a connection has been established with a certain object and data is being transmitted, the state of the disk is set to be unavailable, and at this time, other objects cannot be allowed to connect with the disk; if the current disk is not connected with other objects and data is not transmitted, the state of the disk is set to be available, and other objects can be allowed to be connected with the disk.
In an embodiment of the present disclosure, the disk connection confirmation information refers to information that confirms that a disk can be connected to a target object, and after receiving the information, the target object may establish a connection with the disk to perform data transmission.
In the above embodiment, if a disk connection request sent by a target object is received, it is first determined whether a disk is in an available state; when the disk is in an available state, the connection between the target object and the disk can be confirmed, namely the target object is allowed to be connected with the disk, and disk connection confirmation information is sent to the target object; then, in order to avoid that other objects occupy the disk resources at the same time, the disk needs to be set in an unavailable state after the connection between the target object and the disk is confirmed.
In an embodiment of the present disclosure, the method may further include the steps of:
and setting the disk to be in an available state in response to detecting that the data transmission between the target object and the disk is finished or receiving data transmission finishing information sent by the target object.
In this embodiment, if it is detected that data transmission between a target object and a disk is finished or data transmission end information sent by the target object is received, the target object is considered to have finished a data transmission task, and the disk may be set to an available state for other objects to access.
In an embodiment of the present disclosure, the method may further include the steps of:
and when determining that the disk is in an unavailable state, sending waiting prompt information to the target object, and when detecting that the disk recovers the available state, confirming the connection between the target object and the disk.
In this embodiment, when it is determined that the disk is in the unavailable state, it is considered that the current disk is being accessed by an object and cannot accept an access request of a new object, at this time, wait prompting information may be sent to the target object to prompt the target object to wait for the current access object to finish accessing, that is, to access again when the disk is in the available state, and when it is detected that the current access object finishes accessing the disk and returns to the available state, the connection between the target object and the disk may be reconfirmed, so that the target object establishes a connection between the target object and the disk.
In an embodiment of the present disclosure, the method may further include the steps of:
and arranging the received disk connection requests according to the receiving time sequence so as to process the disk connection requests in sequence.
In order to improve the effectiveness of disk connection and avoid multiple frequent seek operations of a disk, in this embodiment, received disk connection requests are sequentially arranged according to receiving time to form a disk connection request queue, so as to sequentially process the disk connection requests, for example, a disk connection request from an object 1 which is received first is processed first, and at this time, because the disk is in an available state, the connection between the object 1 and the disk can be confirmed, and disk connection confirmation information is sent to the object 1; the object 1 establishes connection with a disk, data reading is carried out, the disk can be set to be in an unavailable state at the moment, the object 1 stores the read data in a data cache space, the connection with the disk is cut off, the disk is restored to be in an available state, the next disk connection request from the object 2 is sequentially processed in a similar mode, and at the moment, the object 1 starts to process the data stored in the data cache space off line; and after the object 1 finishes processing the data, sending a disk connection request to the controller again, wherein the disk connection request is arranged in a disk connection request queue according to the receiving time sequence of the disk, and when the disk connection request is processed in sequence, the object 1 writes the previously processed data into the disk again. According to the data access and transmission flow, the data transmission task can be completed, the occupied time of the disk can be saved, the effectiveness of disk connection is improved, repeated and frequent seek operation of the disk is avoided, the disk throughput is further ensured, the system processing speed is improved, and the system processing capacity is improved.
