DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

Exemplary embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 4. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

A dispatching automation active inspection system mainly comprises system hardware and system software, wherein the system hardware is composed of a data integrated server, a data acquisition server and network security equipment as shown in figure 1, the system is deployed in security areas II and III, the data acquisition server deployed in the security area II acquires device data of the security areas I and II through a firewall security strategy, performs data interaction with service systems deployed in the security areas I and II, and is deployed in a comprehensive data processing server of the security area III.

The system software, as shown in fig. 3, mainly comprises data acquisition service, data analysis service, data forwarding service, data comprehensive analysis service, WEB service, short message service, the system is developed and realized by Java EE standard, adopts a layered model, and mainly comprises a presentation layer, an MVC control layer, a business logic layer, a data access object layer, and a field object layer, wherein the system is developed and realized by Java EE standard, adopts a layered model, and mainly comprises a presentation layer, an MVC control layer, a business logic layer, a data access object layer, and a field object layer, as shown in fig. 2, Java EE components of each layer are coupled together in a loose coupling manner, so as to avoid hard coding coupling, which provides convenience for the expansion of future applications. The implementation of the upper component depends on the functionality of the lower component, which supports the implementation of the upper component.

The system functions mainly include four aspects of service modeling and data acquisition, panoramic monitoring and display, alarm management and system management, and the system functional architecture is shown in fig. 4:

(1) hardware equipment performance data acquisition and data display

The system adopts a common SNMP protocol or a webservice and power 104 protocol interface to collect the running states of equipment and a service system, system event data, performance index data and the like. And setting upper and lower limit values for each different type of specific performance data, and generating corresponding alarm items by the system if the performance data exceeds the upper and lower limit values. The generated alarm items can be sent to corresponding operators on duty according to the system setting.

(2) Hardware equipment topology information acquisition and topology display

The system has the automatic topology function of network equipment, acquires and comprehensively calculates network topology information in an SNMP protocol mode, and periodically scans network topology.

(3) Device and system application auto discovery and modeling design

The system provides device and system application auto-discovery and modeling functionality. The network equipment automatic discovery algorithm mainly uses two protocols, namely SNMP (simple network management protocol) and ICMP (internet control protocol). The function adopts the advantages of simplicity and high efficiency of an ICMP protocol, periodically scans a specified system network segment, pushes a found new IP to an automatic modeling service, and the automatic modeling service acquires model information of new equipment by adopting an SNMP protocol according to the new IP information and carries out a small amount of manual intervention.

(4) Business system data acquisition and data display

The data acquisition of the service system is mainly divided into measurement data acquisition and alarm data acquisition, wherein the measurement data needs to be acquired by the service system of the opposite side in a fixed sequence, the alarm data needs to be submitted in a specified file format, and the data file interaction is carried out by adopting a webservice or ftp mode and the like.
