It is provided with desiccant at described air inlet valve.
All described cargo holds share dry bulb sensor, out of my cabin wet bulb sensor and a control centre out of my cabin.
Being provided with dehumidifier in described cargo hold, described dehumidifier is controlled by described control centre.
The control method of a kind of cargo hold ventilation automated measurement &control system, has following steps: in cabin described in a.
Wet bulb sensor, out of my cabin dry bulb sensor and temperature T in wet bulb sensor records cabin respectively out of my cabin in dry bulb sensor, cabinInterior dry、
Wet bulb temperature T in cabinEndogenous dampness, temperature T out of my cabinOuter dry, wet bulb temperature T out of my cabinExogenous damp, and transmit to described control centre；In the most described control
The heart is according to TInterior dry、TEndogenous dampness、TOuter dry、TExogenous damp calculatesObtain dew point temperature T in cabinInterior d, dew point temperature T out of my cabinOuter d；C. T is worked asOuter d＞ TInterior dTime, described logical
Wind blower fan, air inlet valve and air outlet valve closing, stop ventilating；Work as TOuter d＜ TInterior dAnd TOuter dry＜ TInterior dTime, described draft fan
Closing, air inlet valve and air outlet valve are opened, gravity-flow ventilation；Work as TOuter d＜ TInterior dAnd TOuter dry＞ TInterior dTime, described draft fan,
Air inlet valve and air outlet valve are opened, vigorous ventilation.When in described cargo hold outer air humidity ratio cargo hold, air humidity is big, and
In current cargo tank air humidity again more than some goods to the required value of humidity time, control centre automatically controls dehumidifier and starts,
Cargo hold is dehumidified.
The invention has the beneficial effects as follows:
The present invention detects the air themperature inside and outside cargo hold and air humidity by the wet and dry bulb sensor inside and outside cargo hold, then controls
Center processed automatically controls, according to the temperature and humidity situation inside and outside cabin, the size whether ventilated or ventilate, it is to avoid cargo hold bulkhead and goods
Thing surface produces " sweat ", it is ensured that freight transport quality.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
In embodiment, as it is shown in figure 1, a kind of cargo hold ventilation automated measurement &control system, including at least one cargo hold 1,
It is characterized in that: described cargo hold 1 is provided with in cabin wet bulb sensor 3, out of my cabin dry bulb sensor 4 in dry bulb sensor 2, cabin, out of my cabin
Wet bulb sensor 5 and control centre 6, wet bulb sensor 3, out of my cabin dry bulb sensor 4 and in dry bulb sensor 2, cabin in described cabin
The signal of wet bulb sensor 5 transmits to control centre 6 out of my cabin, is provided with draft fan 7, air inlet valve 8 and goes out in described cargo hold 1
Air port valve 9, described air inlet valve 8 and air outlet valve 9 are electromagnetic valve, and described control centre 6 controls described draft fan
7, air inlet valve 8 and air outlet valve 9 action.The air inside and outside cargo hold is detected by the wet and dry bulb sensor inside and outside cargo hold
Temperature and air humidity, then whether control centre automatically controls according to the temperature and humidity situation inside and outside cabin and to ventilate or to ventilate
Size, it is ensured that cargo hold will not produce " perspiration " when ventilating, it is to avoid cargo hold bulkhead and cargo surfaces produce " sweat ".
The present invention, is provided with desiccant at described air inlet valve 8.Described desiccant can absorb in entering cabin out of my cabin empty
The humidity of gas, can reduce the humidity of air in cabin faster.
The present invention, as it is shown in figure 1, all described cargo holds 1 share dry bulb sensor 4, out of my cabin wet bulb sensor 5 out of my cabin
And control centre 6.The integrating control of multiple cargo hold is easy in control centre 6, and wiring is succinct, just controls cost for the most cargo holds
The lowest.
In embodiment, as shown in Fig. 1, being provided with dehumidifier 10 in described cargo hold 1, described dehumidifier 10 is by described control
The heart 2 controls.When in cargo hold 1 outer air humidity ratio cargo hold 1, air humidity is big, in cabin, air humidity is more than again some goods to wet
The required value of degree, control centre automatically controls dehumidifier and starts, dehumidifies in cabin.
In embodiment, as shown in Fig. 2, there are following steps: wet bulb sensor in dry bulb sensor 2, cabin in cabin described in a.
3, dry bulb sensor 4 and temperature T in wet bulb sensor 5 records cabin respectively out of my cabin out of my cabinInterior dry, wet bulb temperature T in cabinEndogenous dampness, out of my cabin temperature
Degree TOuter dry, wet bulb temperature T out of my cabinExogenous damp, and transmit to described control centre 6；The most described control centre 6 is according to dry, T endogenous dampness, T in T
Outer dry, T exogenous damp calculates in cabin the outer d of d, out of my cabin dew point temperature T in dew point temperature T；C., as d in the outer d ＞ T of T, now it is not suitable for
Ventilating, described draft fan 7, air inlet valve 8 and air outlet valve 9 are closed, and stop ventilating；When dry outside d and T in the outer d ＜ T of T
In ＜ T during d, described draft fan 7 is closed, and air inlet valve 8 and air outlet valve 9 are opened, and enters natural aerofluxus slowly and leads to
Wind pattern, can prevent cargo hold from " perspiring " phenomenon；As d in dry ＞ T outside d and T in the outer d ＜ T of T, showing will not in ventilation process
Occur that cargo hold 1 phenomenon of perspiring can take vigorous ventilation, described draft fan 7, air inlet valve 8 and air outlet valve 9 to open,
Can quickly reduce the dew point temperature in cargo hold.
Obviously, the above embodiment of the present invention is intended to be merely illustrative of the present example, and not to the present invention
The restriction of embodiment.For those of ordinary skill in the field, can also make on the basis of the above description
The change of other multi-forms or variation.Here without also all of embodiment being given poor example.And these belong to this
Obvious change or variation that the connotation of invention is amplified out still fall within protection scope of the present invention.
