Abstract
The invention provides a signal power distributor having perfect function and suitable for various environments, that is a signal power distributor having functions such as lightning protection, signal photoelectrical isolation, single-input multiple-output, and power distribution. In industrial automation system, a communication bus is commonly used for transmitting signals between on-site sensor or transmitter and control center equipment, which has the disadvantages that the transmission line is long and is mainly positioned at terrible environment and that surge overvoltage produced on the line can transmitted to equipments on both sides in two ways along the line to damage the equipments. Lightning electromagnetic pulse on the line produced by lightning strike can not be prevented by common signal isolator or power distributor, and the isolator or power distributor can be damaged by the lightning strike to interrupt signal transmission and influence the normal operation of the system. In order to solve the above problems, an lightning protection device is provided at the signal line input terminal, and the signal enters the photoelectrical isolation portion through the lightning protection device and is outputted after signal isolation for providing power to connection terminal for supplying power to subsequent equipments. Compared by prior product, the product has the advantages that the power distributor can achieve the basic function of signal distributor and self-protection function by combining lightning protection, signal isolation and distribution, and power distribution functions, and that advanced technique is adopted to improve the transmission accuracy and integrate multifunction as whole, thereby reducing size, saving assembly space, reducing signal attenuation in transmission process, and achieving convenient assembly and maintenance.
Description
Technical field
The present invention relates to a kind of Signal Spacing distributing equipment, specifically relate to a kind of active signal distributor that has anti-surge function and input and output are carried out the photoelectricity isolation.
Background technology
In industrial automation system, the signal transmission of adopting communication bus to carry out spot sensor or transmitter and control center's equipment room more, the long and many places of circuit are in the more abominable place of environment, the terminal device of the overvoltage surge of Chan Shenging road along the line transmitted in both directions invasion on the line causes damage to equipment.Adopt signal isolator or distributor that the equipment end signal is isolated, prevent that the high voltage that produces on the transmission line from producing harm to equipment, be simple and effective technical measures, though present signal isolator or distributor can be realized the Signal Spacing function, and the photoelectricity of employing isolation method is also arranged, realize the voltage isolation between input and output signal.But, the Lightning Electromagnetic Pulse that produces on the circuit during for thunderbolt, general signal isolator or distributor, then can not play buffer action, and isolator or distributor itself can suffer the influence of Lightning Electromagnetic Pulse and damage, cause transmission signals to interrupt, influence the normal operation of system.If will carry out lightning protection, then need lightning arrester to be installed in front equipment end, increased installation cost and space, improved cost.Existing signal isolator and distributor are two kinds of products, cannot change mutually, and be relatively poor for the Installation Flexibility of site environment.
Summary of the invention
The purpose of this invention is to provide a kind of signal distributor that is applicable to all-environment perfect in shape and function, promptly have the signal distributor of functions such as lightning protection, the isolation of signal photoelectricity, the output of single channel input multichannel, distribution.
The problem that in use exists of signal distributor in the market: 1, can only isolate, surge currents such as Lightning Electromagnetic Pulse can not be isolated or filtering to being included in the signal normal pulsed and interference; 2, do not possess the self-protection function, when suffering Lightning Electromagnetic Pulse, the photoelectricity isolated part is very easily damaged and is caused protecting actual effect or signal interruption, and might cause equipment to damage when follow-up thunderbolt; 3, if install Surge Protector separately additional signal isolator or distributor and equipment are protected, installing space is increased, and its a large amount of connection lead not only increased workload and also increased the trouble spot, makes troubles for construction and maintenance, and strengthened cost; 4, can not distribute and the photoelectricity isolation output signal; 5, signal isolator and signal distributor are two kinds of products, can not change mutually, at different environment for use very flexible.
Product of the present invention has proposed corresponding solution at above problem: be provided with lightning protection device at the signal line input end, signal is gone into the photoelectricity isolated part by lightning protection device is laggard, carry out Signal Spacing and distribute back output, the connection terminal of powering for follow-up equipment can provide power supply.
Concrete scheme:
1, is provided with lightning protection device at the signal line input end, adopt the hot swap type lightning-protection module, when lightning-protection module inserted, signal circuit at first passed through lightning protection device entering signal isolated part again, when lightning-protection module is extracted, the direct entering signal isolated part of signal circuit; And lightning protection device interrupts inserting mode with taking nothing being connected of signal hop, can not cause the signal interruptions in transmissions in module plug process, and the detection of being convenient to lightning-protection module is changed.
2, adopt photoelectric isolation technology, and carry out the isolation between each road, promptly when multichannel is exported,, avoid the influence of the disturbing pulse on output terminal or the power circuit isolating respectively between each road output signal, input signal and output signal, signal and the power supply.
3, installing distribution selector switch is provided with switch on panel, selects whether to have distributing function, can self-adaptation select during environment change at the scene.
4, the product mounting means is installed for the standard guide rail, and going out connection terminal carries out outside the power supply input, also power supply can be combined with guide rail, signal distributor is directly powered by guide rail, and provide power supply for equipment, the guide rail power supply is convenient to signal distributor installation side by side as a kind of mode of power supply input.
Product of the present invention is compared with existing product; its advantage is: lightning protection, Signal Spacing distribution and distributing function are integrated; the basic function and the self-protection function of signal distributor have been realized; sophistication has improved transmission precision, and multiple function is integrated, has reduced volume; saved installing space; reduced the decay in the signals transmission, and easy for installation, easy to maintenance.
