The setting of formula, address etc. are called in RAM, it is ensured that the parameter for arranging during upper electricity every time is not lost.
Thinking of the present utility model is that as core, concrete principle is as follows to improve air quality in switch cubicle：
1st, in switch cubicle air condition by equipment run produce temperature rise cause air themperature to rise, by cabinet outside（That is looped network
Case is interior, cable duct）Into dust and aqueous vapor to make in cabinet air that temperature height, high humidity, dust stratification is presented more.Formed in switch cubicle
The reason for stating air condition is that the heat that equipment comes out in switch cubicle raises the air themperature in cabinet, forms one heat empty
Gas, as the density of the density ratio cold air of hot-air is low, therefore hot-air rises toward at the top of switch cubicle, so as to the shape in the cabinet
Into one air-flow from bottom to top, cabinet inner bottom part is caused to form a negative pressuren zone, the outer air of cabinet will be from the passage of cabinet bottom two
Fill in cabinet, one is there is gap due to switch cabinet wall, cabinet door, and in cabinet outer container, air can be filled in cabinet from this, two be due to
Switch cubicle is connected with cable duct, although there is clay to block in cabinet, former through aspects such as prolonged operation, stress, deteriorations
Cause, may cause fine gap occur, and cable duct air can be thence in cabinet.
2nd, environment control mode in looped network case：
（1）Cooling, wet down：Using the outer time dependent rule of aerial temperature and humidity of looped network case and the building enclosure of looped network case
With the attenuation to the outer air themperature humidity change of case, then by intelligent environment control system reality described in the utility model
Operation ventilation during trade looped network case outer air low temperature, low humidity, stops divulging information when looped network case outer space upward adverse flow of QI temperature, high humidity, reach by
Outside case, relative Cryogenic air and low-humidity air replace relative high temperature air or relative highly humid air in case, come empty in control ring net cage
The temperature and humidity of gas.When the outer air of case is in high temperature or high humidity state can not meet that control is required in case, system can be automatically
Close air intake.At this moment such as in case, humidity meets or exceeds setup parameter, and system enables dewatering type electronic dehumidifying device to guarantee automatically
In case, humidity is in the range of setting.
（2）Case inner air-cleaning：By looped network case inner air and outer air metathesis, it is ensured that the discharge of harmful gass in case；And
The outer air of case to entering carries out high efficiency filter by airstrainer, while malleation is kept in case, outdoor dust cannot be from door
The gaps such as hole enter, so as to ensure the cleaning of air in looped network case.
3rd, air quality control and anti-condensation in switch cubicle：
This utility model has abandoned traditional by implementing the anti-condensation measure such as heating in cabinet, but empty in cabinet by reducing
Gas water capacity makes the dew point temperature of air less than the surface for not allowing condensation part occur reducing the dew point temperature of air in cabinet
The anti-condensation method of temperature.The outer blower fan pressurization of Jing casees, makes looped network case and switch cubicle inner air pressure relative atmospheric be in malleation so that
Can only flow from top to bottom with the air at the gap between cable duct in switch cubicle bottom, prevent the entrance of cable duct humid air and opened
Close cabinet, in addition in cabinet outer container air humidity control, reduce the water capacity of air in cabinet, it is ensured that the dew point temperature of air in cabinet
Less than equipment surface temperature in cabinet, so as to reach purpose anti-condensation in switch cubicle.
4th, the intellectuality of system administration：
Looped network case intelligent environment control system not only realizes equipment（Blower fan, dehumidifier）Intelligent management function, and
The teletransmission of various information can realize thering is GPS location when sending alarm by wireless, cable network.Such operation maintenance personnel
The running environment situation of looped network case can be understood in any place, any time in real time, the very first time grasps looped network case, cabinet by broken
Bad information.Pinpoint the problems in time, it is quick to process, substantially increase the safety and reliability of looped network case equipment operation.
5th, warning function：When case inner sensor failure, case outer sensor failure, Smoke Sensor failure, smog alarm, case
In interior temperature over-range, case humidity transfinite, open alarm, alarming shift, dehumidifier failure, looped network case control mainboard by it is mobile eventually
End sends alarm signal；When gate control system is illegally opened, buzzer warning and SMS alarm can be passed through.
Outdoor ring network case ambient intelligence control method described in the utility model, comprises the following steps：
1st, set fan operation thresholding：
The outer high temperature upper lower limit value of case is 33 DEG C, the outer temperature/humidity sensor of 31 DEG C, i.e. case detects box outside temperature and rises to 33 DEG C
When, blowing-out machine；When the outer temperature/humidity sensor of case detects box outside temperature and drops to 31 DEG C, blow in machine；
When the outer low temperature upper lower limit value of case is 7 DEG C, the outer temperature/humidity sensor of 5 DEG C, i.e. case detects box outside temperature and is down to 5 DEG C,
Blowing-out machine；When the outer temperature/humidity sensor of case detects outer temperature and rises to 7 DEG C, blow in machine；
When the outer humidity upper lower limit value of case is that the outer humidity of 80%, 75%, i.e. case rises to 80%, blowing-out machine；The outer humidity of case is down to 75%
When, blow in machine；
2nd, the high low speed service condition of blower fan：
When the thresholding of fan operation is met, it is divided to two humidity sections, blower fan to be separately operable height in the outer humidity of case below 75%
Speed and low speed；The upper lower limit value of two humidity sections is 65%, 60%；When the outer humidity of case is below 60%, blower fan high-speed cruising；
When the outer humidity of case rises to 65%, blower fan is by switching at a high speed low cruise；
3rd, dewatering type electronic dehumidifying device operation thresholding：
When in case, humidity rises to the setting upper limit（Such as 80%）When, open dewatering type electronic dehumidifying device；When in case, humidity is down to and is set
Put lower limit（Such as 75%）When, close dewatering type electronic dehumidifying device；When dewatering type electronic dehumidifying device is opened, blower fan is in halted state.
In order to solve the environmental problem of prior art medium ring net cage generally existing, this utility model is by affecting equipment fortune
Air condition and its change in air parameter, switch cubicle in the lot of essential factors of row the environment such as internal and external environment of looped network case, cable duct
Measurement with analysis, with the methods such as field experimentation test, calculation of thermodynamics, aerodynamic principle and technological means, to case
The temperature rise of interior equipment and its heat effect, thermo parameters method, humidity change, ash be dirty to be formed, the physical phenomenon such as generation of condensation in cabinet
Carry out it is qualitative and quantitative research and analyse, scientifically propose new thinking on this basis, affect looped network case all multi-environments
Key element and its demand for control such as ventilation, cooling, antifouling, anti-condensation, dry are integrated and are balanced by computer unification, are defined
With in Based Intelligent Control ventilation and dehumidifying, pressure reduction switch board, the technology such as air humidity content, photoswitch, communication and GPS location is as core
The anti-broken scheme of the environmental Kuznets Curves of the heart, forms an intelligent environment control system.
Looped network case intelligent environment control system described in the utility model is that a kind of sensor application, computer of being based on is controlled automatically
