Cloud is protected:
Cloud service center can provide data and run the large type protection of control two, is specially:
One, data protection
Air-cooled cold (heat) water unit 301 runs the historical data controlled; automatically long lasting protective storage is carried out by Cloud Server 304 database of cloud service center; related data regularly carries out adding up, analyzing automatically, with the object of the reasonable maintaining and use that realize scientific guidance air-cooled cold (heat) water unit 301.
Two, Control protection is run
Air-cooled cold (heat) water unit 301 is provided with online (cloud) and non-online two kinds of operational modes, when Cloud Server because the reason such as poisoning is in collapse conditions, can not use or out of hand time, in order to ensure the normal operation of air-cooled cold (heat) water unit 301, (cloud) and non-online two kinds of patterns can switch automatically online, and specific requirement is as follows:
1) run when air-cooled cold (heat) water unit 301 is in online (cloud) mode state, if the self-inspection of air-cooled cold (heat) water unit 301 exceedes setting-up time (as 10 minutes) from the network control signal break period that the Cloud Server 304 of cloud computing center sends, as 1 failure logging, when continuous fault record reaches number of times (as 3 times) of setting, namely be automatically converted to non-line model to run, now machine runs according to the original control parameters preset when dispatching from the factory and control program, in running, machine no longer accepts the control instruction that Cloud Server 304 sends, the adjustment of operational factor can only carry out manual adjustment by user 309 oneself on air-cooled cold (heat) water unit 301 control panel, run to network recovery always, and till the recovery time (as 60 minutes) reaching setting continuously, now be automatically converted to online (cloud) mode operation, if in running, Cloud Server 304 finds to occur virus by self-inspection, and due to the reason of virus, occur that the data arranged are distorted by improper, short time can not recover, and now the Cloud Server 304 of cloud service center is by automatic cutting-off controlling signal, and air-cooled cold (heat) water unit 301 is automatically converted to non-line model according to above-described Logic judgment and runs, until Cloud Server 304 recovers normal, till again receiving control instruction.
It should be noted that above about adding up failure logging to determine that Cloud Server 304 is abnormal, and determine that Cloud Server 304 recovers to illustrate normally the restriction that should not be construed as the embodiment of the present invention.This citing only for determining the running status of Cloud Server 304, is understandable that, can also have a variety of implementation, and the embodiment of the present invention will not limit this.
2) under air-cooled cold (heat) water unit 301 is in the operation of non-line model state, run as needs proceed to (cloud) mode state online, only need connected network, give relevant control instruction by cloud computing center Cloud Server 304.
In above embodiment; air-cooled cold (heat) water unit of band cloud function; by the powerful calculating of the Cloud Server of cloud service center, service ability, realize inquiring about the cloud of air-cooled cold (heat) water unit, cloud controls and cloud protects this three large characteristic Intelligent Service function.
The inquiry of its medium cloud can realize: air-cooled cold (heat) water unit real time execution parameter, by wired or be wirelessly transmitted to cloud service center Cloud Server, user can pass through the equipment such as computer or radio communication, with wired or wireless mode, receive air-cooled cold (heat) water unit real-time running data by Cloud Server platform.
Cloud controls to realize: user is according to individual character, differentiation needs, by demand information by the equipment such as computer or radio communication, be transferred to the Cloud Server of cloud service center, through Cloud Server analysis, process, control signal is sent to air-cooled cold (heat) water unit in mode that is wired or wireless transmission, air-cooled cold (heat) water unit runs according to the demand of user, to realize the demand of user personality, differentiation.
Cloud protection can realize: the service provided by cloud computing center, on the one hand can to air-cooled cold (heat) water unit history data automatic storage, regular statistics, analysis, with the object of the reasonable maintaining and use that realize scientific guidance air-cooled cold (heat) water unit; In addition on the one hand; energy automatic diagnosis; by the service of online (cloud) and non-online two kinds of operational mode automatic switching functions that provide air-cooled cold (heat) water unit, to protect air-cooled cold (heat) even if water unit also can normally run under Cloud Server is in paralyzed state.
Adopt embodiment of the present invention scheme, air-cooled cold (heat) water unit by the calculating that utilizes Cloud Server powerful, service function, the aforementioned drawback that by the service of cloud service platform, effectively can overcome, avoid air-cooled cold (heat) water unit to exist.
In addition, one of ordinary skill in the art will appreciate that all or part of step realized in above-mentioned each embodiment of the method is that the hardware that can carry out instruction relevant by program completes, corresponding program can be stored in a kind of computer-readable recording medium, the above-mentioned storage medium mentioned can be read-only storage, disk or CD etc.
These are only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the embodiment of the present invention discloses, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
