The invention discloses an online monitoring device and an online monitoring method for the boiling degree of a blast-furnace gas boiler economizer. The online monitoring device comprises a data acquisition unit and a data processing unit, wherein a unit distributed control system is used for acquiring he running data of a blast-furnace gas boiler, and the boiler economizer in a high-temperature section and a low-temperature section, and storing the running date in a real-time database server and a mirror image database server; a calculation server is used for reading the running data from the mirror image database server, carrying out calculation processing to obtain a calculation result of the boiling degree of the boiler economizer in the high-temperature section, and storing the calculation result in the mirror image database server; a WEB publishing server is used for publishing the calculation result to a user display terminal; the user display terminal can look up the value of the boiling degree of the boiler economizer in the high-temperature section, and carry out boiler running on the basis to control the boiling degree of the boiler economizer in the high-temperature section, thus the boiler economizer in the high-temperature section is in a safe state, so as to guarantee the safe and stable running of the gas boiler, and prolong the service life of the blast-furnace gas boiler economizer.

The invention discloses a cloud cipher service platform based on a virtualization technology and a working process of the platform. The platform comprises a management center and multiple nodes. The center is responsible for basic configuration, checking and arithmetic logic of applications, application entry management, registration, maintenance and management of the nodes, virtual cipher machine and mirror image management and total life-cycle management of application secret keys. Each node is composed of multiple relatively independent cipher machines, and different virtual cipher machines are isolated on each node through the virtualization technology, and each container is responsible for cipher operation services of a specific application. According to the cloud cipher service platform based on the virtualization technology and the working process of the platform, various disadvantages of the cipher machines in a traditional application mode are overcome, the cipher service performance is improved, combination and distribution according to needs of cipher services are achieved, and the application requirements of high performance and high availability on the cipher services under cloud computing are met.

The invention discloses a cement mill multi-parameter intelligent integrated monitoring system, which belongs to the technical field of industrial monitoring. It includes a monitoring center, a main control box arranged next to the cement mill, and monitoring points are respectively set at multiple monitoring parts of the cement mill. Center connection; the monitoring center establishes and displays the 3D model of the cement mill, and marks the data collection points in the 3D model of the cement mill according to the actual data collection positions of the monitoring points. The data collection points are linked to the corresponding data charts, and the monitoring center represents the data through different colors Whether the data in the collection point is within the set threshold. The present invention can carry out overall on-line monitoring of electricity, oil products, etc. of the cement mill, and solves the shortcomings in the prior art that the monitoring of the cement mill is scattered and cannot be monitored as a whole.

The invention discloses a blast-furnace gas boiler economizer boiling degree on-line monitoring device and method. The monitoring device comprises a data acquisition unit and a data processing unit. Operating data of a gas boiler are collected through a unit distributed control system, the collected operating data are stored in a real-time database server and a mirror database server, a calculation server reads the operating data from the mirror database server and processes the operating data to obtain economizer boiling degree calculation results, the calculation results are stored in the mirror database server, a WEB publishing server publishes the calculation results to a user display terminal, and a user can look up the calculation results in real time through the user display terminal and master the operating conditions of an economizer in time. If the economizer boiling degree excesses a set upper limit value, the user can lower the economizer boiling degree in time through the boiler operation adjustment, so that the economizer is in the safety state, the safety operation of the blast-furnace gas boiler is accordingly guaranteed, and the service life of the blast-furnace gas boiler economizer is accordingly prolonged.

The invention discloses an alarm organization method for a client in a communication network management system. The client organizes each alarm received from a server into a tree structure, which includes the following steps: first, select an alarm; then, judge the selected Whether the alarm has a parent alarm that has been attached to the tree structure, if so, hang the alarm under the parent alarm node, otherwise, determine the group to which the alarm belongs, and hang it in the group of the group below the node. The technical scheme of the invention realizes the hierarchical organization of alarms.

The invention discloses a transmission-line security risk state evaluation method. The transmission-line security risk state evaluation method comprises the following steps of building a line danger source occurrence probability model gamma {T, alpha<k>, k=1, 2, ... , 12, beta}, wherein the line danger source occurrence probability model comprises a parameter danger source type T, a type beta of line faults leading to danger sources, and the occurrence probability alpha<k> of each month of a year, wherein k=1, 2, ... , 12; determining the occurrence probability E<1> of the first type of faults of a sectional line, wherein E<1> satisfies the equation (please see the equation in the specification), and determining the occurrence probability E<2> of the second type of faults of the sectional line, wherein E<2> satisfies the equation (please see the equation in the specification); determining the security risk state of the line through the occurrence probability E<1> of the first type of faults and the occurrence probability E<2> of the second type of faults. According to the transmission-line security risk state evaluation method, on the basis that the line danger source occurrence probability model is built, transmission-line security risk state evaluation is achieved by combining line fault cost, and assistant decision-making data are provided for patrol work arrangement of the line according to an evaluation result.
