Eastern Digital Rack Serial Server Used in Computer Room Monitoring System Solution of TCP/IP Network

Computer room monitoring system scheme based on TCP/IP network

----- You can use Oriental Digital 1 / 2 / 4 / 8 serial port networking server

I. Introduction

The centralized monitoring system for power environment is used for telemetering, remote sensing, and remote control of various parameters, images, sounds, etc. of switching power supplies, air conditioners, oil machines, batteries, high and low voltage power distribution, and other equipment and environments of distributed communication bureaus (stations). Real-time monitoring of its operating parameters, diagnosis and processing of faults, recording and analysis of relevant data, so as to achieve the purpose of a small or unattended communications bureau (station), and centralized monitoring of equipment, centralized maintenance and centralized management.

II Status of Existing Monitoring Systems

The main transmission methods of the local network monitoring system are DDN, Modem, ISDN, and 2 Mbit/s private lines, all of which are point-to-point transmissions. Considering that the DDN and 2 Mbit/s leased line resources in the access network are limited, the real-time monitoring performance of the Modem and ISDN transmission modes is not stable. If point-to-point transmission is used, there are too many central equipments and the operating and maintenance costs are too high. Therefore, most systems today are 2 Mbit/s extraction slot mode. Existing supervision

The network status of the control system is shown in the figure:

III Monitoring System Based on TCP/IP Network Transmission

With the development of broadband networks, it becomes easier and easier to obtain broadband network resources at various access points. By using these broadband network resources and adopting the TCP/IP method, access points can easily establish contact with the monitoring and management center and the database, and at lower cost, the power equipment, room environment, security, and fire protection of access points can be used. The video and other information are monitored under a unified platform.

The system based on TCP/IP network transmission mode is shown in the figure:



On the site of the telecommunications access network equipment room, a TCP/IP-based on-site serialized networking server unified monitoring platform was set up to centrally monitor the power equipment, computer room environment, and security and fire protection systems in batches. The various devices, serial ports, and protocols of each system can be integrated. It is possible to directly access the access point network rooms through the serial port software to implement monitoring. Due to the establishment of a unified platform, after an investment, only gradually add external serial devices, you can gradually complete the power equipment, computer room environment, security and fire protection, the system based on the TCP / IP network structure of centralized monitoring.

IV Comparison between 2Mbit/s extraction time slot and TCP/IP network

Application category

Using 2Mbit/s extraction time slot

Using TCP/IP network

Price cost

The time slot card is relatively expensive, and both ends of the SU and the data collector are loaded with a time slot card, and the cost is relatively high.

Serial server is lower in price compared to serial server. Only one serial server can be loaded on the data collector to achieve communication between them.

transfer speed

Slower transmission

Faster transmission speed

Commissioning and maintenance

Can not determine the cause of the fault in a timely manner, it is not clear where the line and the line at both ends of the fault

Simple and convenient commissioning and maintenance

Networking

Network is not flexible

Flexible networking

Five East Digital Product C2000 Performance Features

1. Features:

C2000 can realize the function of directly converting serial port data transmission to TCP/IP data transmission. After packing the serial port data of the SM end of the system, it can be easily put on the network, and then it can be quickly and steadily transmitted to the SU end through the TCP/IP network, resulting in more transmission performance. Fast and stable.

2. reliability:

(1) Dongfang digital product C2000 adopts double watchdog circuit design, which ensures safer operation of the converter and is more reliable.

(2) Eastern Digital's C2000's low work consumption, such low power will make the converter run without heat, so that the system and peripheral equipment without any influence, more stable operation;

(3) Dongfang Digital actively provides test software with automatic sending and receiving functions to customers, and urges users to continue testing the converters through the computer for a period of time. It promises that even if data of several tens or even hundreds of megabytes are transmitted, no data loss or error will be lost. ;

(4) Dongfang Digital provides three-month free replacement and five-year quality warranty service for the product C2000.

3. Ease of use:

(1) Dongfang Digital Products C2000 has a virtual serial port driver, the user's software can be used without any modification;

(2) Dongfang Digital provides communication dynamic libraries and dynamic libraries for users with high integration requirements, and the method of operation is simple, making the C2000 more user-friendly;

(3) Dongfang Digital can also provide users with a variety of development tools under the program source code, so as to facilitate the user's secondary development of the product.

VFD Grid

Vacuum fluorescent display, referred to as VFD, is a low-energy electroluminescent display devices, the working principle and CRT similar. It has the incomparable advantage of liquid crystal display (LCD) in applications where there is a large variation in ambient brightness and no strict requirement for low power consumption, and is now widely used in audio-visual equipment, home electronics, automotive instruments, office equipment and instrumentation.

The structure of a VFD board is a typical vacuum triode structure, consisting of a cathode, a grid and an anode. In between the cathode and the anode there's a thin mesh of metal called the Grid that can be switched on or off, controlling the flow of electrons from the cathode to the anode. This VFD grid mesh is made of a thin metal plate with a thickness of 30 to 50μm, which is lithographed and made into a highly transparent fine lattice or tortoise-shaped metal mesh. When a positive voltage is applied to the grid, electrons emitted from the filament are accelerated and diffused toward the anode. When a negative voltage is applied to the grid, electron flow to the anode is cut off.

We custom VFD Grid with drawings provided by customers. The raw material we use for etched VFD Grid is SUS430 stainless steel. We are equipped with professional metal etching equipment and exposure development equipment. Our etched manufacturing capacity can achieve 0.05mm.
