Digital Optical Engineering Field Strengths In A Variety Of Applications

Monitor the project site environment is complex

, and in the transmission part of the traditional program, the more is the use of coaxial cable, in many cases, strong electric and magnetic fields can not be avoided interference, installing anti-jamming device, Amplifiers Become engineers frequently used method, but this method not only increasing the total project cost, while addressing the effects tend to be poor. In some larger projects, the laying of the cable very large quantities, engineering difficulties attendant will be greatly increased, often a long construction period.

The same time in a Monitoring System Into the commissioning stage, progress is often slow, and troubleshoot and resolve a small issue often take a long time, the test run, and after delivery, are likely to occur such as the failure phenomenon: or device is not running, or not meet the system design requirements Technology Index, or overall performance and quality is not satisfactory, some of the so-called "soft defects." These issues for a project for a monitor, especially for a complex, large-scale monitoring project is inevitable.

And on the last few years, Optical transmission only had to take long-distance communication means, as high raw material costs, digital technology immature and so on, a lot of close-transmission or transmission quality requires high did not get a wide range of application. However, as the core technology of digital control, reducing the cost of raw materials, coupled with its almost "zero degradation" of the perfect transmission effect, making it too large a number of close monitoring of the use, and it reflects the high cost of advantage is unmatched by other transport means.

If we Optical transmit and receive unlimited range to narrow the optical transmission and the traditional way will not be any different, so we say that an optical fiber to replace all the wires, or we believe that Optical is a line. Any Product The launch of the final works are to be applied to them to go, to use the convenience and stability is the concern of engineers carrying out Optical Digital Design should be possible to consider the perspective of engineering applications, it can reflect at the scene of many advantages.

Line help engineers determine the point of failure

No video signal and no control signal is often in the installation and maintenance problems often occur, perhaps cause of the malfunction is very simple, but the more often the more difficult small place was found. That when no video signal, to 11 to check Video camera Check the master device, Optical inspection, inspection fiber optic line ... ... there is no control signal, control line to check whether the short-circuit or open circuit, Also check the master device, check the agreement ... ... in engineering debugging process, these traditional transmission line fault discrimination is very cumbersome, and would cost a lot of time and effort. Now worked out a number of Optical light through the machine body can determine where the fault point, and the ability to know "whether the video signal input," "fiber-optic line attenuation is within the dynamic range," " output channel is normal. " These features called "knowledge to see light line", that could be done to install, debug, targeted, and this advantage in a large construction site has been highly recognized by engineers and greatly shorten the debugging cycle.

Transmission quality of the edge Cable transmission line interference is the most troublesome problem engineers in a number of large factories and mines, the strong electric field, magnetic field interference is inevitable, sometimes very close distance less than the effect of transmission, this time more think of is to install anti-jamming, amplifiers and other equipment, but only increased the project cost, while this solution is often a temporary solution, because it is only in the inhibition of interference signals, and can not be completely ruled out. Can be understood that any form of transmission network with a cable, the internal circulation are electrical signals, signal interference and mutual influence is almost inevitable, but the wiring can be a more reasonable way to choose a better profiles, or use some external interference suppression equipment to solve. The use of optical and digital Optical transmission network constructed, the internal circulation of all optical signals, it is almost a "vulnerable to the attack", and then a strong electric or magnetic field will not have any of it, to receive them The video is almost no distortion, known as the "perfect" transfer effect.

Engineering capacity and project cost advantages

Is well known, monitoring field Optical transmission distance is often up to several tens of kilometers or even hundreds of kilometers, in fact, close to the transmission range, it works on the volume and cost advantages are quite obvious. Fiber-optic communications impression in people's traditional means of transmission is more expensive, and now has completely changed, cable prices are almost three years ago, 1 / 10, or even the price of cable is even lower than many, especially digital Optical Optical self-mastered with the domestic manufacturers the core technology, the prices have been moving more rational, economic. In many engineering programs, even if not very far away from the use of Optical transmission program has been cheaper than cable. As an alternative to the multi-optical satellites are video cable, audio cable, or control lines. For example, we used the eight-way video data Optical reverse way, its a single-mode fiber to resolve the eight video lines and eight control lines need to be resolved; In addition, the project also greatly reduced the amount. Therefore, the total price of cable and Optical cable is far less than the price, Optical transmission distance is no longer transmitted on behalf of Noun , Which from a costly transmission into a low-cost, high-quality transmission options; the same time, basic maintenance is also a fiber-optic communications without the late great advantage.

In general, close to use Optical transmission has been replaced by cable can not only improve the quality of the project is also the low-cost solution. This stage, the number of Optical has been widely applied to the project site in. Simplicity in operation, transmission quality, volume and cost of the project's overall strength has been more obvious. Can be expected in a growing number of project site, the Digital Optical Terminal application more widely throughout the security industry, it will play more important role, as a transmission equipment, will inevitably lead the field of a transmission revolution.
