Accompanying drawing explanation
Accompanying drawing 1 is data center of the present invention dual power supply many precision air conditioners control system schematic diagram.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention will be described in detail.It should be noted that, specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
This data center's dual power supply many precision air conditioners control system; including Host Protection control system with from machine Protection control system two parts; described Host Protection control system and all use dual-cpu structure from machine Protection control system core; communication module is set respectively under CPU structure; LCD display module, human-machine interface module and control and protection module；Described Host Protection control system and between machine Protection control system by handshake exchange information, described Host Protection control system and the communication module from machine Protection control system are all connected to CAN；Described Host Protection control system and the control from machine Protection control system are connected power supply and chopper respectively with protection module, and precision air conditioner is connected to each chopper.
Described dual-cpu structure includes 8 AVR single chip and 16 bit DSP IC single-chip microcomputers.
Described 8 AVR single chip, as host computer, connect communication module, LCD display module, human-machine interface module, and existing LCD shows, man-machine interaction and CAN communication function.
Described 16 bit DSP IC single-chip microcomputers, as slave computer, connect and control and protection module, be responsible for timely collection data, perform protection algorism, protect precision air conditioner and control.
Described Host Protection control system and the control from machine Protection control system are connected 2 choppers respectively with protection module, and each chopper connects 1 precision air conditioner.
Due to Host Protection control system and the systems from machine Protection control system being 2 separate mutually complementations again; this just requires that Host Protection control system not only will be clear that native system state in which with from machine Protection control system, simultaneously it is further understood that complementary system state in which.So engine control system and need to communicate in some way between machine control system.Because precision air conditioner Protection control system must continue air feed, so must put into operation immediately when main shut-down system from machine by strict guarantee machine room.
But CAN is as a kind of software communication mode, complementary system can cannot be made to receive the frame of expression the other side's duty in the very first time due to reasons such as the complicated and changeable of machine room working environment or the delays of software protocol own.From the standpoint of the reliability and seriality of air conditioning system, this is unallowed.So, this data center's dual power supply many precision air conditioners control system have employed hardware based complementary system communication mode.
