A system integration company based on the NORCO series industrial computer power equipment and environmental monitoring system, has now been widely used in telecommunications, mobile company room, base station power environment monitoring project.
System Requirements:
In the early telecom room and mobile base station systems, multi-star class networking was widely used. The line has 2M or 2M time slot demultiplexing mode, serial communication mode, and Ethernet mode; it is also common in base station systems. The dry contact method, serial bus method, 2M time slot add/drop method, etc. are required to adapt the monitoring system to each user's line resource status.
1. The software and hardware of the monitoring system should adopt a modular structure so that it has flexibility and extensibility to meet the needs of different scales of monitoring system networks and different numbers of monitoring objects.
2. The use of the monitoring system should not affect the normal operation of the monitored equipment and should not change the original functions of the equipment with internal automatic control functions.
3, the monitoring system should have good electromagnetic compatibility. When the monitored equipment is in any working state, the monitoring system can work normally; at the same time, the monitoring equipment itself should not produce electromagnetic interference that affects the normal operation of the monitored equipment.
4. The monitoring system should be able to monitor a variety of equipment with different grounding requirements. The access to any monitoring point should not damage the grounding system of the equipment being monitored.
5, the monitoring system should be able to adapt to a variety of transmission methods provided by mobile communications, should not affect the communication transmission.
6. The system monitoring should have self-diagnosis function, which can automatically recover data disturbances, communication disturbances, etc.; it should be able to diagnose faults and timely alarms for communication interruptions, software and hardware failures, etc.; the monitoring system should not affect the monitored equipment when it fails. The normal work and control functions.
7. The monitoring system hardware should be able to work uninterruptedly under the basic power supply conditions provided by mobile communication equipment rooms around the country. When the power supply is restored, it should be able to start running automatically.
8. The monitoring system should have a friendly human-machine dialogue interface and Chinese character support capabilities; fault alarms should have clearly visible audible signals.
9. In the monitoring system, the measurement accuracy requirements of the system composed of independent monitoring subsystems are:
DC voltage should be better than 5%;
· Battery cell voltage error should not exceed 5mv;
· Other electricity should be better than 2%;
Non-electricity should generally be better than 5%;
· The switch quantity should be 100% accurate.
10. In the surveillance system, a system composed of independent monitoring subsystems shall have an alarm response time of less than 5 seconds in the presence of a link, a data response time of less than 10 seconds, and a command execution time of less than 10 seconds.
11. The monitoring system shall have the basic functions of alarm management, configuration management, and security management.
12, can complete the monitoring of the image when there is a demand.
system introduction:
1. System Structure:
The monitoring system adopts a cascaded topology structure. A tree network topology can be formed by the centralized monitoring center SC, the regional monitoring center SS, the monitoring unit SU, and the monitoring module SM. The setting of the power and environment centralized monitoring system of the communication office (station) can be set. Relatively independent, it is a subsystem of the local network management. Within a local network, the centralized monitoring center SC enters the local mobile network management center.
2. System network structure:
3. Design of on-site monitoring unit SU:
4. Monitor the design of the transit station ZSS:
5. Design of Regional Monitoring Center SS:
6. Centralized monitoring center SC design:
The centralized monitoring center accesses multiple regional monitoring centers SS through data interface B, and can realize the functions of multiple regional monitoring centers SS on the same operating platform and on the same interface. It is equipped with remote signaling, telemetry, remote control and remote adjustment functions, alarm functions, configuration functions, security management functions, report functions, communication management functions, display functions, and printing functions.
7. Front-end machine
The front-end processor, also known as the front-end processor and monitoring host, is mainly used to process telemetry and remote-remote data from various monitoring modules and to issue remote control and remote adjustment commands to the monitoring module. It is responsible for handling the details of the data communication with the monitoring module, and inherits the functions of sequentially transferring data from different monitoring modules to other software modules of the monitoring system.
Due to the core role of the monitoring host, its reliability requirements are very high. Generally, NORCO series IPCs are used. The basic configuration is as follows:
Chassis: RPC-900 (4U, multi-drive position rack mount chassis)
CPU Card: NORCO-740VE (P4 Industrial CPU Card)
CPU: P4 1.8G
Memory: 512M (DDR 266)
Hard disk: 80G*8
Network Interface: 10M/100M, TCP/IP Protocol Display: 15"
Operating System: WANDOWS 2000/NT
Database System: Micosoft SQL Server
Optional accessories:
1) MOXA multi-serial card, depending on the communication mode of the monitoring module;
2) Dedicated image and voice collection compression card, depending on the needs of audio and video surveillance.
System Features:
The software and hardware of the monitoring system adopts a modular structure, which is flexible and expandable, so as to adapt to the requirements of different scales of monitoring system networks and different numbers of monitoring objects.
The monitoring system realizes the functions of distributed power, remote equipment, remote measurement, remote control, and remote adjustment of each equipment in the environmental system, real-time monitoring of the operating status of the system and equipment, recording and processing of relevant data, timely detection of failure, notification Personnel processing to achieve the mobile communication room of the few or unattended, and power, environmental monitoring and maintenance management, improve the reliability of power systems and mobile communications equipment security.
Practice has proved that this monitoring system operates in multiple sites, and it is safe, reliable, with no missing reports or misstatements. It is the best choice for centralized monitoring of the power and environment of telecommunications industry communication equipment rooms.
