Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] As shown in FIG. 1 , a network diagram of an IPTV equipment upgrade system. The entire upgrade process consists of a device upgrade client, an upgrade server, and devices to be upgraded (upgrade device-1, upgrade device-2, . . . , upgrade device-n). The device upgrade client controls the upgrade process, and the upgrade server is responsible for the transfer of upgrade files. The upgrade client and the upgrade device interact through messages, and the upgrade server, the upgrade device, and the upgrade client perform file transfer through FTP (File Transfer Protocol, file transfer protocol).

[0028] As shown in Figure 2, the application example of the present invention can realize the process control method process of state memory and recovery, including the following steps:

[0029] Step 201, the user crea...

Abstract

A flow control method is provided for implementing the state memory and recovery, which comprises the steps: (1) a user establishes an equipment upgrade task file while dividing the transaction into a plurality of processing procedures based on the transaction processing type of upgrade flow control, each processing procedure has several time sequences, each time sequence of the processing procedure is added with a mapping relationship between the time sequence and the state; (2) the equipment update operation is performed based on the equipment upgrade task file, and the operational state is solidified in real time during the flow operation process, to allow each time sequence to correspond to the related state; (3) if the flow is exited during the flow operation process, the correspondingly-stored state information can be found out by the time sequence of the exit and the state is recovered. The invention can reduce the workload of failure repair, realize the manual control of the flow operation effect, and can reduce the time of failure repair of automated flow control.

Description

technical field [0001] The invention relates to the field of automatic process control, in particular to a process control method capable of realizing state memory and recovery. Background technique [0002] Current automated process control is generally guaranteed by process control software running on one or several computers. The current method of flow control processing is generally: according to the type of transaction processing, the transaction is divided into several processing steps, and each processing step can be divided into several time sequences, and there are strict dependencies between time sequences and steps. This process control method is widely used in industrial automation production and office automation. [0003] However, this approach to flow control has some big drawbacks: [0004] 1) During the processing of the process, if the operating environment changes so that a certain sequence cannot produce the correct result, the entire process will stop ...
