Description
Technical field
The present invention relates to server unit field, more specifically, relate to a kind of caching server educating platform based on school altogether.
Background technology
In more and more informationalized today, the customer group faced by motion education becomes millions, and it must build a high property prolongable back-end system framework and concurrently access greatly to support.System design uses the independently developed distributed processing framework of excellent letter and builds high availability application based on Ali's cloud service.In order to adapt to the demand, Calculation of the shunted current pressure, application service system based on mobile office is made up of several application servers.In order to improve the access performance of application program, the data buffer storage that some are conventional can be increased substantially in internal memory access efficiency, thus reduce database and the physical access of Web server.Caching server is the important component part of application service system.But, existing caching server system, its lightning protection ability is weak.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of caching server educating platform based on school altogether, it has lightning protection function, and its lightning protection ability is strong.
The present invention solves the problems referred to above and be the technical scheme is that
A kind of caching server educating platform based on school altogether, it is characterized in that: include server and the power supply of electric energy is provided for server, connect between described power supply and server and have lightning protection circuit, described lightning protection circuit includes leadage circuit and the protection circuit being sequentially connected with, described leadage circuit includes that the first comparator and base stage are connected to the triode of the first comparator output terminal, the colelctor electrode of described triode is connected on power supply and grounded emitter, described power supply passes sequentially through the first resistance, second resistance is connected with the negative electrode of diode, the plus earth of described diode, two inputs of described first comparator are connected to the two ends of the second resistance, the colelctor electrode of described triode is connected with protection circuit.The present invention improves on the basis of existing caching server, i.e. arranges lightning protection circuit between power supply and server, protects thunder and lightning, it is to avoid server is damaged by emergency case.The lightning protection circuit of this programme includes the leadage circuit of prime and the protection circuit of rear class, and the thunder and lightning acting on server is released by leadage circuit, it is ensured that follow-up protection circuit and server properly functioning；After thunder and lightning is not released complete or its circuit malfunction by the leadage circuit of prime, protection circuit is started working, and reaches to protect purpose.The power supply of this programme leadage circuit produces dividing potential drop on the first resistance and the second resistance, and the second resistance both end voltage is input to the first comparator, and diode produces the reference voltage of comparator.When normally working, second ohmically dividing potential drop is not enough to drive the first comparator output drive signal, and when thunder and lightning acts on power supply, the second ohmically dividing potential drop increases, first comparator detects that when voltage is excessive, output signal opens triode, by the current drain of transistor collector.
As preferably, described protection circuit includes the second comparator and FET, the drain electrode of described FET is connected with the colelctor electrode of triode by the 3rd resistance, two inputs of described second comparator are connected to the two ends of the 3rd resistance, the output of described second comparator is connected to the grid of FET, and the source electrode of described FET connects on the server.The protection circuit of this programme includes the second comparator, and when normally working, the voltage at the 3rd resistance two ends is little.Thunder and lightning acts on the leadage circuit of power supply and prime and is not released by thunder and lightning completely or during its circuit malfunction, and the second comparator detects that the 3rd resistance both end voltage is excessive, and output signal turns off FET, reaches to protect purpose.
As preferably, described diode is Zener diode.
As preferably, the Standard resistance range of described 3rd resistance is 50 megohms to 200 megohms.Resistance not only acts as FET cut-off signals monitoring effect, and it also functions to metering function, and when thunder and lightning is not released complete or its circuit malfunction by leadage circuit, subsequent electronics is easily damaged by big electric current, therefore the resistance of resistance should be within the specific limits.
To sum up, the invention has the beneficial effects as follows:
1, the lightning protection circuit of the present invention includes the leadage circuit of prime and the protection circuit of rear class, and the thunder and lightning acting on server is released by leadage circuit, it is ensured that follow-up protection circuit and server properly functioning；After thunder and lightning is not released complete or its circuit malfunction by the leadage circuit of prime, protection circuit is started working, and its lightning protection ability is strong and reliability is high.
2, the leadage circuit of the present invention uses comparator and triode etc. to constitute, and its lightning protection ability is strong.
