Understandable, except above-mentioned 7 large Type Control functions, other function can also be expanded as required, with the needs of satisfied different client.
Cloud is protected:
Cloud service center can provide data and run the large type protection of control two, is specially:
One, data protection
Water cooled chiller 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, with the object of the reasonable maintaining and use that realize scientific guidance water cooled chiller 301 automatically.
Two, Control protection is run
Water cooled chiller 301 is provided with (cloud) and non-online two kinds of operational modes online, 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 water cooled chiller 301, (cloud) and non-online two kinds of patterns can switch automatically online, and specific requirement is as follows:
1) run when water cooled chiller 301 is in (cloud) mode state online, if water cooled chiller 301 self-inspection 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 water cooled chiller 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 water cooled chiller 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 water cooled chiller 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, the water cooled chiller of band cloud function, the powerful calculating of the Cloud Server by cloud service center, service ability, realize inquiring about the cloud of water cooled chiller, cloud controls and cloud protects this three large characteristic Intelligent Service function.
The inquiry of its medium cloud can realize: water cooled chiller 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 water cooled chiller 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 water cooled chiller in mode that is wired or wireless transmission, water cooled chiller 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 water cooled chiller history data automatic storage, and regular statistics, analysis, with the object of the reasonable maintaining and use that realize scientific guidance water cooled chiller; In addition on the one hand; energy automatic diagnosis; by providing the service of online (cloud) of water cooled chiller and non-online two kinds of operational mode automatic switching functions, even if to protect water cooled chiller also can normally run under Cloud Server is in paralyzed state.
Adopt embodiment of the present invention scheme, water cooled chiller 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 current water cooled chiller to exist.
It should be noted that, connected by network or wireless mode control multiple stage (or modularization) water cooled chiller quantity can have a lot, the embodiment of the present invention will not limit this.
One of ordinary skill in the art will appreciate that: all or part of step realizing method in above-described embodiment can have been come by the hardware that programmed instruction is relevant, aforesaid program can be stored in a computer read/write memory medium, comprising some instructions in order to make a computer equipment (can be personal computer, server, or the network equipment etc.) perform all or part of step of method described in each embodiment of the present invention.And aforesaid storage medium comprises: USB flash disk, portable hard drive, read-only storage (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), magnetic disc or CD etc. various can be program code stored medium.
