Abstract
Description
technical field:
The present invention relates to electronics, computerized information field, electric equipment monitoring field, particularly relates to a kind of intelligent SPD equipment based on Internet of Things.
background technology:
Surge protector (Surge Protective Device; SPD) claim again Surge Protector; to limit the release non-linear protective device of surge current of transient overvoltage and guiding for electrified system, in order to protect electrical equipment that withstand voltage level is low or electronic system to exempt from the infringement of thunderbolt and LEMP or switching overvoltage.In recent years, electronic information (as TV, phone, communication, computer network etc.) development is swift and violent, and electronic message unit emerges in multitude and popularizes.This type systematic and equipment are often more expensive and important, and its operating voltage, withstand voltage level are very low, are very easily subject to the harm of Lightning Electromagnetic Pulse, need to adopt SPD to do overvoltage protection for this reason.But SPD product of a great variety, protected mode is varied, causes in use procedure and has also occurred a series of confusion,, even also there is a lot of SPD spontaneous combustion on fire in the not only protection weak effect of SPD, serious harm is to the safety of equipment.The security performance of SPD also becomes the major issue of numerous communications industries and user's concern.Below, by research be correlated with last word and utility model patent, technical background of the present invention is described.
Patent-surge protector Site Detection and control device (201220263505) are realized by controlling between two poles successively and connecing surge protector (SPD) fault-signal warning circuit and SPD protection switch actuating signal warning circuit, though the method reaches the object of fault alarm and disengagement failure SPD, but SPD needs the time to change new equipment after cutting off, fault is got rid of and lagged behind, bring new potential safety hazard to power supply-distribution system; This is designed to single SPD and independently monitors simultaneously, can not feasible region property monitoring, alarming, and management actual effect is low, thereby brings the wasting of resources.The wireless remote automatic monitoring system (201220068618) of patent-highway lightning protection SPD realizes wireless malfunction and reports to the police, and fails equally to address the above problem.Patent-surge protection device (201210092200) has been realized a kind of modifying device of surge protection, but it does not take into full account himself lost efficacy protection inefficacy and the potential safety hazard brought.Patent smart lightning monitoring device (201210009222.0) is realized temperature detection and is monitored SPD module operating state, the method can only qualitatively judge in theory, and change and have larger error with ambient temperature, therefore utilize the method to judge that the SPD difficulty that whether lost efficacy is larger, poor reliability.
summary of the invention:
The object of the invention is intended to overcome above-mentioned technical problem; a kind of intelligent SPD equipment based on Internet of Things is proposed; intelligence SPD equipment has merged the technology such as traditional lightning-arrest over-voltage protection module, sensing detection, embedded system and Internet of Things, cloud computing; fast except thering is the response time; outside the large general SPD feature of through-current capacity; equipment is also equipped with high-performance processor, transducer, high-performance AD, memory, Internet of Things transport module.Can be applicable to low high-tension line equipment protection, include but not limited to building, communication, security protection, finance, IT application in enterprises, industrial automation, railway traffic, electric power, wind-powered electricity generation, military affairs, petrochemical industry, coal industry.
The object of the invention is to realize by following measures:
Based on an intelligent SPD equipment and system for Internet of Things, comprising: intelligent SPD equipment, Internet of Things communications platform, cloud FTP client FTP and Cloud Server system.
Described intelligent SPD equipment, comprises lightning-arrest over-voltage protection module, redundancy protecting module, standby power supply module, sensing detection module, embedded system and Internet of Things communication port;
