Detailed Description
The present application will be described in detail with reference to the specific embodiments shown in the drawings, but these embodiments are not limited to the present application, and structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present application.
Referring to fig. 1, an embodiment of the present application provides a monitoring system for operation of large-scale instruments and devices, where the system includes a server 11 and a plurality of upper computers 12, and the server 11 is communicatively connected to each upper computer 12. Each upper computer 12 is communicatively connected to a corresponding one of the instrumentation devices 13. The upper computer 12 acquires the update identification and the modification time information of the modification time of the communication log file of the instrument device 13, and transmits the update identification, the modification time information and the identification information of the instrument device 13 to the server 11, wherein the update identification is used for indicating whether the modification time of the communication log file is changed. The server 11 determines the run time of the instrument device 13 based on the update identification, the modification time information and the identification information of the instrument device 13. The communication log file is stored on the host computer 12. The communication log file is used for recording data communication between the upper computer 12 and the instrument 13 and recording the operation condition of the instrument 13. After the instrument 13 starts the power-on operation, control operations are performed on the instrument 13, which are to be performed by a program installed in the host computer 12, and these operations are recorded in a communication log file of the host computer 12. When the instrument 13 starts the power-on operation, the modification time of the document, which is the communication log file stored in the upper computer 12, is changed. Therefore, the upper computer 12 records the updated modification time by monitoring whether the modification time of the communication log file of the instrument 13 changes or not, and uploads the recorded modification time to the server 11, and the server 11 can determine the running time of the instrument 13, so that the running time of each instrument can be managed, the effective management of the use of the instrument can be realized, the instrument with lower use rate can be discovered in time, the utilization rate and sharing rate of the instrument can be improved, and the scientific research cost can be reduced.

The function call module 121 obtains modification time information of the communication log file by calling windows to provide an interface function Getfiletime () of the user. The determining module 122 monitors whether the modification time of the communication log file changes within the first time threshold, if so, sets the update identifier as a first update identifier, records the update identifier as a current latest modification time stamp, and if not, sets the update identifier as a second update identifier, and records the update identifier as a last modification time stamp. For example, the first time threshold is set to 30 minutes, the determining module 122 monitors whether the modification time of the communication log file changes within 30 minutes, if so, the change means that the modification time of the monitored communication log file is inconsistent with the modification time of the last monitored communication log file, which indicates that the communication log file is changed, which indicates that the instrument device is in a power-off to power-on state or is always in a running state or is in a power-on to power-off state, the first update identifier is set to 1,1 indicates that there is a change, and the current latest modification timestamp of the communication log file is recorded. If the modification time of the communication log file is unchanged within 30 minutes, which means that the communication log file is unchanged, the instrument is in a shutdown state, and setting the second update identifier to 0,0 means that the communication log file is unchanged. According to the technical scheme, the attribute of the modification time of the communication log file is monitored to determine the running time of the instrument and equipment, hardware equipment such as a sensor is not required to be installed, the monitoring of the running time of the instrument and equipment is realized through software, the influence on the instrument and equipment is avoided, and meanwhile, the scientific research cost is reduced.

Illustratively, the second time threshold is set to 2 hours, the change of the modification time of the communication log file in 2 hours is counted, and the change of the modification time of the communication log file counted each time is recorded. According to the above embodiment, the determining module 122 monitors the change condition of the modification time of the communication log file every 30 minutes, if the change is set to 1, and records the latest modification time of the communication log file, if the change is not set to 0, and records the last modification time of the communication log file, so that the monitored change condition is counted every 2 hours, and the counted change condition is recorded and stored. Based on the technical scheme, the change condition of the counted communication log file modification time is stored locally on the upper computer 12, and monitoring data does not need to be frequently sent to the server 11, so that the operation and resource utilization of the upper computer 12 are not affected.
As an alternative implementation manner, the identification information of the instrument device 13 may be the number of the instrument device 13, or the identification information for uniquely identifying the instrument device 13, and the upper computer 12 stores the identification information of the instrument device 13. The identification information of the instrument 13 may also be represented by the MAC address of the host computer 12, because one instrument corresponds to one host computer, and the MAC address may uniquely identify the instrument.
As an alternative implementation, as shown in fig. 2, the upper computer 12 further includes a generating module 124 and a sending module 125. The generating module 124 uses the recorded data of each time as a line of data according to the first update identifier and the corresponding current latest modification timestamp recorded by the statistics module 123 or the second update identifier and the corresponding last modification timestamp, so as to obtain a plurality of lines of data, and further generate a CSV file. The generating module 124 generates a CSV file according to the modification time variation of the communication log file recorded by the statistics module 123, and records the modification time variation monitored each time in each line of data of the CSV file. Illustratively, assuming that the first row of data includes a first update identifier of 1 and the corresponding modification time is 8:00, the second row of data includes a first update identifier of 1 and the corresponding modification time is 8:30; the third row data includes a first update identifier of 1, a corresponding modification time of 9:00, the fourth row data includes a first update identifier of 1, a corresponding modification time of 9:30, and the fifth row data includes a second update identifier of 0, a corresponding modification time of 9:30. The transmitting module 125 transmits the CSV file and the MAC address of the host computer 12 to the server 11.

The receiving module 112 receives the MAC address of the upper computer 12 sent by the upper computer 12, and according to the MAC address of the upper computer 12, the storage module 111 queries and obtains the identification information of the corresponding device 13, so as to determine from which device the received CSV file comes. The parsing module 113 parses the CSV file sent by the host computer 12, reads the CSV file row by row, obtains the corresponding current latest modification timestamp when the data line containing the first update identifier is read, obtains the corresponding last modification timestamp when the data line containing the second update identifier is read, and performs a difference operation based on the two obtained modification timestamps to obtain the running time of the instrument 13. According to the CSV file described in the above embodiment, when the first row of data is read, the first update identifier is 1, the modification time is 8:00, and the first update identifiers in the second row of data to the fourth row of data are all 1, it is indicated that the modification time of the communication log file of the instrument device 13 is always updated, which indicates that the instrument device 13 is always running, and when the second update identifier of the fifth row of data is read is 0, it is indicated that the modification time of the communication log file of the instrument device 13 is no longer updated, which indicates that the instrument device 13 is in the off state, thereby it can be determined that the running time of the instrument device 13 is 1.5 hours. According to the technical scheme, the running time of the instrument 13 is determined by detecting the change condition of the communication log file modification time of the instrument 13, the accuracy is high, the instrument with lower use rate can be found in time, and the use rate of the large instrument is improved.
