Description
Technical field
The present invention relates to a kind of machine room, be specifically related to the tele-control system of a kind of building environment.
Background technology
The physical environment of machine room has been affected by strict control, is broadly divided into several aspect: i.e. temperature, power supply, floor, anti-
Fire system.Mentioning temperature, general is all air-conditioning.Air-conditioning is used for controlling the temperature and humidity of data center, and refrigeration is with empty
" the hot criterion of data processing circumstance " suggestion temperature range adjusting engineering association is 20-25 DEG C, and humidity range is 40-55%, fitness number
It it is 17 DEG C according to the maximum dew point temperature of center environment.Hot-air can be added in data center power sources, unless heat is excluded away, no
Then ambient temperature will rise, and causes electronic equipment malfunctioning.By controlling air themperature, server component can keep manufacturer
In the range of the temperature/humidity of regulation.Air conditioning system helps to control humidity by air drop in cooling chamber to dew point, and humidity is too
Greatly, water may start to condense on the inner member.If in a dry environment, auxiliary humidification system can add steam,
Because if humidity is the lowest, electrostatic discharge problem may be caused, components and parts may be damaged.The power supply of machine room is by one or more
Uninterrupted power source and/or diesel-driven generator composition stand-by power supply.In order to avoid Single Point of Faliure occurs, all power systems, including
Stand-by power supply is all full redundancy.For server key, two power supplys to be simultaneously connected to, to realize N+1 redundancy system
The reliability of system.Static switch is used for guaranteeing that moment is switched to another electricity from a power supply when there is power failure sometimes
Source.The floor of machine room to promote 60 centimetres relative to tile floor, and this height becomes higher with social development, is 80-100 li
Rice, to provide more preferable air-flow to be uniformly distributed.So air conditioning system can also be poured into cold air under floor, is also underground simultaneously
Electric lines of force wiring provides more sufficient space, and the data cable of modern data center is typically via the laying of overhead cable dish,
But still data wire still should be routed under floor by some people suggestion for security consideration, and consider to increase cooling system.Little
The floor not having lifting in type data center can be without antistatic floor.Computer cabinet is often organized into a passage of heat
In, in order to the efficiency that ventilates is best.The fire prevention system of machine room includes passive and active design, and fire prevention action performs meter
Draw.Smoke detector would generally be installed, fire alarm can be found in advance before burning produces naked light, permissible before the intensity of a fire increases
Blocking power supply, make to spray fire extinguisher manually fire extinguishing.Automatic sprinkler can not be used, because electronics is first in data center
Device would generally break down after meeting water, makes the situation of fire-fighting by water can become even worse in the case of particularly power supply does not blocks.I.e.
Make to be mounted with that automatic sprinkler system, cleaning gas extinguishing system also should start early than automatic sprinkler system.In data
Fire wall also should be installed in center, so can be controlled in subrange by burning things which may cause a fire disaster, even if breaking out of fire can also will be damaged
Mistake reduces to minimum.
Existing building environment controls typically to use field control, needs staff to regulate and control equipment to scene,
The machine room that some danger or remote area is set up, such as relating to the machine room of nuclear reaction equipment, it is clear that safety ratio is relatively low.
Summary of the invention
The technical problem to be solved is that machine room typically uses field control, it is therefore intended that provide a kind of machine room ring
The tele-control system in border, solves that some machine room field control danger is higher or far less convenient problem.
The present invention is achieved through the following technical solutions:
The tele-control system of a kind of building environment, including CAN, display module, processing module, external signal input module
