Embodiment 1

[0043] refer to figure 2 , is a flowchart of a log recording method in a device control process according to Embodiment 1 of the present invention.

[0044] During the operation of various process equipment, log records are carried out by the equipment control system. The equipment control system generally includes functional modules such as IO (input and output), Control (control), Alarm (alarm), Interlock (interlock), Recipe (process formula), Setup (configuration), and a large number of Log information, the following process will complete the recording of these log information.

[0045] Before starting the log recording process, you first need to configure the log recording method in the log configuration file. The specific configuration content includes the threshold value of the number of log files, which modules need to record logs, and log level restrictions. After the configuration is complete, start the following logging process:

Embodiment 2

[0067] Based on the content of the first embodiment, this embodiment provides a more specific logging method, which is as follows.

[0068] In this embodiment, the equipment control system includes functional modules such as IO (input and output), Control (control), Alarm (alarm), Interlock (interlock), Recipe (process formula), Setup (configuration); log levels are based on severity From low to high, it is divided into VERBOSE (detailed and lengthy information), EVENT (important event information), PROBLEM (problems that occur when the program is running, although it is not normal but not an error), ERROR (error information) and FATAL ( Fatal error message) five levels. The log configuration file records configuration information such as "log file storage path", "threshold value of log file quantity", "which modules record logs", "log levels of modules that record logs".

Embodiment 3

[0108] Based on the contents of the foregoing method embodiments, this embodiment provides corresponding device and system embodiments.

[0109] refer to Image 6 , is a structural diagram of a log recording device in a device control process according to Embodiment 3 of the present invention.

[0110] The log recording device may include a configuration parsing unit 61 , a new or open unit 62 , a file quantity detection unit 63 and a log recording unit 64 . Wherein, the configuration parsing unit 61 is used to read the log configuration file and analyze it to obtain the preset log file quantity threshold value in the log configuration file; the new or open unit 62 is used to create a new log file or open an existing log file; The number of files detection unit 63 is used to detect whether the number of log files that have been created exceeds the threshold value of the number of log files, if exceeded, then delete according to the preset strategy, until the number of ...

Abstract

The invention provides a method, a device and a system for recording logs in the equipment control process, which aim to solve the problem of log management. The method comprises the following steps of: 1, reading a log configuration file, parsing and thus acquiring a log file number threshold value which is preset in the log configuration file; 2, creating a new log file or opening the existing log file; 3, detecting whether the number of the created log files surpasses the log file number threshold value or not, and if the number of the created log files surpasses the log file number threshold value, deleting according to a preset strategy until the number of the created log files is less than or equal to the log file number threshold value; and 4, acquiring log information to be recorded and recording the log information to be recorded into the new log file or the opened existing log file. By the invention, the automatic management and maintenance of the log file number are realized, and the severe result that an industrial personal computer crashes because a hard disk is fully written by the log files is thoroughly avoided.

Description

technical field [0001] The invention relates to log recording technology, in particular to a log recording method, device and system in the equipment control process. Background technique [0002] In computer systems or various network systems, log records are very necessary. In the process control process of semiconductor manufacturing, the control systems of various process equipment often perform log records. These logs record various information of the controlled equipment during operation, and this information is the main basis for tracking the operation process of the equipment and recalling accidents. [0003] The information recorded in the log is usually saved in a fixed file format, and each record usually includes information such as the recording time, the name, level, and content of the module (or subsystem) that records the log. refer to figure 1 , showing a typical device control system log. Wherein, the recording time of the log is 2009-07-22 09:18:46.334...
