Problems solved by technology

The original alarm receiving and handling system adopts C / S architecture (client-server architecture), and the traditional C / S architecture has a narrow scope of application; the user group is fixed, and because the program needs to be installed before it can be used, it is not conducive to the promotion and deployment of the system ; Maintenance costs are high, once an upgrade occurs, all client programs need to be changed
[0003] The original Client / Server (Client / Server) structure is a relatively traditional and commonly used software system architecture. By reasonably assigning tasks to the Client (Client) and Server (Server) ends, the deployment and maintenance of the system The overhead is high, and the client needs to be installed on site to perform management operations

specific Embodiment approach

[0023] A system for receiving and handling alarms based on B / S architecture, the specific implementation is as follows:

[0024] (1) Including at least 4 servers, Linux A and B, and Linux C and D; keepalived is installed on Linux A and B to realize virtual IP, keepalived on both Linux A and B servers point to the same virtual IP , and perform two-way heartbeat detection;

[0025] (2) A is configured as the host and takes over the virtual IP. At this time, B is used as the backup machine. When A server is shut down for maintenance or downtime, keepalived on B will automatically take over the virtual IP to ensure that the service is available;

[0026] (3) Nginx is installed on Linux A and B to achieve load balancing. The two Nginx configurations are similar, and they are both configured as reverse proxy for the lower-level tomcat server;

[0027] (3) The balance strategy is configured as IP hash to maintain the session of the client and the police service; the static resources...

Abstract

The invention provides an alarm receiving and handling system based on B / S architecture. The system comprises at least four servers, keepaliveds are installed on Linux A and Linux B, virtual IP is achieved, the keepaliveds on the Linux A server and the Linux B server point to the same virtual IP, and bidirectional heartbeat detection is carried out; Wherein A is configured as a host computer and takes over the virtual IP, B is used as a standby computer, and when the server A carries out shutdown maintenance or downtime, the keepalived on the B takes over the virtual IP automatically; Tomcat is installed on the Linux C and the Linux D, alarm receiving and handling server programs are deployed, alarm receiving and handling programs achieve alarm receiving and handling related services, database operation is conducted, and meanwhile butt joint with other external programs is completed.

Description

technical field [0001] The invention relates to a B / S architecture-based system structure of a police receiving and handling system, which belongs to the improvement of technical methods in the field of police receiving and handling systems and command and dispatch systems in public security informatization. Background technique [0002] With the rapid development of Internet technology, the deployment of information systems has higher requirements for functions such as mobility, convenience, and easy maintenance. At the same time, the cloud migration of the system is imminent. The original alarm receiving and handling system adopts C / S architecture (client-server architecture), and the traditional C / S architecture has a narrow scope of application; the user group is fixed, and because the program needs to be installed before it can be used, it is not conducive to the promotion and deployment of the system ; Maintenance costs are high, and once an upgrade occurs, all client...
