Embodiment Construction
[0027] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0028] A storage device for power cable tunnel monitoring data, such as figure 1 As shown, it includes a real-time library, a cache module, a hard disk, and a history library. The cache module includes a data area and a management area. The data area collects power cable telemetry data in real time from the real-time library, and organizes the data into a hash list in memory; the management area In the process of saving the data in the data area as a file, generate the corresponding Record record, and modify the corresponding information in the Record record when the data that needs to be saved in the history database changes. In the process of writing the contents of the data area to the hard disk, each piece of data stored in the hash list is saved as a file, and one data of each telemetry value in each file is saved as a data snapshot, and a Re...

The invention provides a power cable tunnel monitoring data storage and query method and device. The method comprises the steps that power cable telemeasuring data is obtained in real time, accordingto the telemeasuring ID of the power cable telemeasuring data, a hash chain table of the telemeasuring data is built, and collected power cable telemeasuring values are correspondingly stored into thehash chain table in a blocked mode; each block of data stored into the hash chain table is saved as a file and stored into a hard disk, one piece of data of each telemeasuring value in each file is saved as a data snapshot, meanwhile, each file generates a record, and a record group is further formed. The writing speed is increased, it is ensured that the same telemeasuring data is ordered according to time and can be written into one adjacent area in a file, the situation that the whole file is retrieved in the query process is avoided, the speed of searching for power cable monitoring datais increased, and a powerful data support is provided for analysis of the power cable data in an abnormal state.
Description
technical field [0001] The invention belongs to the technical field of comprehensive automation of power cable tunnels in power systems, and in particular relates to a storage and query method and device for monitoring data of power cable tunnels. Background technique [0002] With the continuous development of urban construction, the corresponding urban power supply facilities have also developed rapidly. As the carrier of power transmission, cables have gradually formed a large-scale power supply network under the city. Power cable tunnels provide a huge number of cables for installation and inspection. With the development of power cable tunnels, the diameter of power cable tunnels and the ability to transmit power have increased, and the monitoring requirements for power cable tunnels have also gradually increased. The modern intelligent monitoring system integrating visualization, intelligence, and unmanned has gradually replaced the original traditional management mode...
