With the advancement of science and technology leap, the world has entered the digital, information technology, network age, radio and television broadcasting also will be rapid development and become multi-form, multi-link, multi-function, multi-level large-scale systems . Complete set of radio and television programs, the need to go through program production, broadcast, program delivery, signal transmission, signal monitoring multiple links and signal reception, etc., every step requires a corresponding broadcasting equipment.
China's current broadcast television industry can Hundred Flowers to describe a variety of emerging technologies emerge. At the same time, with the development of radio and television broadcasting equipment manufacturing industry has grown. From analog to digital television, either SD or HD signals require signal requirements, quality and technical level of China's radio and television equipment to meet the basic requirements, in some areas have been living in the world advanced level.
From the situation in recent years, the State Administration of Radio equipment bidding, the domestic broadcasting equipment also has certain advantages. At present, China's quality broadcasting equipment in the late editing programs, and other aspects of broadcasting and transmission, have reached the world level. In the pre-recording equipment, domestic companies are catching up, I believe that with good domestic standard of perfection and the constant introduction of industrial policy, China's broadcasting equipment levels can continue to improve.
Current trends in digital broadcasting equipment industry is very clear, on the basis of the digital, high-definition, secure, controllable gradually put on the agenda. The future, as technology advances and evolving technology, broadcasting equipment market space is still very large, especially from analog to digital, from SD to HD, every technological innovation will bring new market space. In the broadcast industry increasingly AV / IT-oriented situation, broadcasting equipment industry, huge space for development prospects.
Digital Television Center (or IDC) room service is currently booming, the reliability of its power management solutions, security, maintainability needs to be greatly improved. In the room with loads mainly a variety of computers, servers, disk arrays and other loads. At present, the construction of a digital television system AC uninterruptible power systems (UPS) building facing the following problems:
1) UPS power supply arrangement showing the dispersion condition, the post-stage AC electrical equipment to take power of concentration;
2) Supply Scheme UPS system is not reasonable;
3) UPS variety, in addition to the mainstream manufacturers, there are many small manufacturers of products, good and bad;
4) UPS input and output system configuration showing the status quo is not entirely justified;
5) the use and maintenance of the status of the UPS, for various reasons, it is not ideal.
Based on the global forefront of technological advantages, woqiquan company provides users with a full range of radio and television industry, digital television system UPS power solutions that enable users to program closer to reality, the entire UPS system more reliable, more secure, easier to maintain.
The following is a few specific digital television room of program analysis:
1) digital television broadcasting system in Guizhou center of a room configuration options:
Program analysis:
The Radio and Television Information Network Company is the largest specialized Area Broadcasting Network, Digital TV overall translation Radio and TV Tower is located in the front room fifth floor, the building area of approximately 600 square meters. UPS system vital role in the room.
UPS power supply mainly to the main computer equipment to provide uninterrupted power supply. The program uses woqiquan Uranus (Uranus) Series Industrial UPS 30kVA UPS and running industry-wide application of the composition 1 + 1 redundancy and system reliability is a stand-alone 5.5 times.
Analysis program elements:
In today's broadcasting system and other important room uninterruptible power supply systems, in order to ensure that the load is not important because failure UPS, batteries, internal module system, causing power outages and other problems in the current technical conditions, the use of "N + 1" type UPS redundancy and power supply system is the best program to eliminate these failures. It is to ensure that the UPS units of the inverter output power in the same magnitude, with the same frequency and phase of the condition (appeared in "Circulation" zero between various single UPS), the "N + 1" Taiwan has the output of the same output power of a single UPS placed parallel output state to run the power supply system. This advanced machine program and much better than the stand-alone operation of the UPS as well as other ways to run hot backup.
Using N + 1 redundancy and high reliability of the power supply system in the following areas:
1. Make sure there is a UPS failure, the load will still be able to provide all highly reliable uninterrupted power supply.
2, redundancy and load electricity system brings significantly improved reliability, and reliability of such power load of 99.999% or even higher.
3, in the customer's business grows, the load equipment for expansion, only the existing systems for expansion and can, without having to create a new UPS system, thus corresponding cost savings for customers, and still maintain a high reliability of the power supply system.
2) Hangzhou, a broadcasting system information room configuration options:
Programme summary
In digital television broadcasting system using the system construction Uranus (Uranus) Series Industrial UPS N + 1 redundancy and system, can provide customers with highly reliable power supply system, so the parallel program points and recommended indicators are as follows:
A decentralized direct parallel, UPS recommends direct parallel, without increasing and cabinets, has built-in automatic bypass and maintenance bypass. Users save floor space, reduce purchasing costs and for future expansion.
2, requires high precision parallel current standards, so that all UPS units unbalanced load <2%, circulation <1A.
3, and the machine must ring signal bus connections, simple and reliable, automatic redundancy.
4, between the UPS units can automatically coordinate, users do not need to focus on the boot sequence; the overload switch to bypass the system can automatically recover; even after the failure of a station out of operation UPS, UPS still remaining stable operation.
5, monitoring software application especially for Chinese customers, we recommend are full Chinese Windows interface, intelligent monitoring software available for free directly connect all the UPS.
With the rapid development of the broadcasting industry, we have reason to believe, UPS power supply system will also provide a strong power protection with higher quality and more reliable power solutions for the broadcast industry.
