At a temperature of the growth and breeding condition of the mould of described satisfied generation aflatoxin, limit value and humidity lower limit are divided
It it is not 25 degree and 80%RH.
Information for 3G network sends framework, and the information conveyance figure place of its unit interval has than conventional homogeneous network
The highest improvement, is substantially all and can exceed that 3 megabits per second, but 3G link system is the most loaded down with trivial details, because the intensity of information reduces
Also has the impact of clutter, it becomes possible to make information conveyance stop temporarily and again carry, so allow information block, very
High information content and real-time the lowest in the case of, this defect is the most serious, if this defect cannot be processed, necessarily will appear from very
The loss of the message group of multi information, allows information conveyance cannot realize correctness.
In order to prevent the loss defect of message group, the information also do not disposed often just first must be write the hard disk of computer
In, information described herein is gravimetric value and the local computing now of the rice in the cabinet D1 of computer server to be sent to D9
Time, and described information is presented in message group, until just information being performed defeated when there is the link of energy in 3G network
Sending, but the hard-disk capacity of general computer is little, particularly PAD is the least, so the hard disc archetecture of computer is how
Building the most critically important, former pattern is to arrange the hard drive space being sized a pair, the respectively first hard drive space and second
Hard drive space, when the first hard drive space and the second hard drive space are all without message group, just can receive the message group of information, and handle
It is written to the first hard drive space, and in real time the message group of the first hard drive space is performed disposal, synchronously can also be then
Receiving the message group of information, they are written to the second hard drive space, the message group in the first hard drive space is disposed and is terminated by the time
After rear and conveying also terminates, such first hard drive space can also then receive the message group of information, can also performing of synchronization
Disposal to the second hard drive space, the carrying out thus gone round and begun again, such pattern realizes under conventional data delivery system
Good effect, but under the conditions of 3G network, once occur the intensity of information to reduce the impact also having clutter, it becomes possible to make
Information conveyance stops temporarily and again carries, the message group of such a pair hard drive space even disposing and finishing, but also without
Method carries, and the most just cannot then receive the message group of next group, because under conditions of being in 3G network, unit interval
The figure place of the message group of the information sent is many, if repeatedly cannot receive message group, the loss of a lot of information i.e. occurs, so this
Quasi-mode is defective in 3G network.
So, in order to solve this problem, it is proposed that following method:
The hard disk of described computer contains Y the hard drive space being cleared, and Y is the positive integer not less than 3, controls at described PLC
When weight processing module in device D4 processed is sent to the gravimetric value of the rice sent in the cabinet D1 come in computer, send here
Cabinet D1 in the gravimetric value of rice be to send over the form of message group, then carry out the disposal of following steps:
Step 1a: foreground message processing module relies on the order of message group got and sequentially writes be cleared hard
In disk space；
Step 2a: synchronize the message group of write to perform disposal, at this by the order of write when finishing step 1a
The mode put is exactly that local computing time now described in step 5 is added to message group, disposes the message group after terminating and depends on
So sequentially performing conveying, described conveying is namely sent to server by 3G network, after conveying End Of Text Block, hard disk is empty
Between empty, make the hard drive space being cleared；
Step 3a: receive follow-up message group, circulation performs step 1a and step 2a so that hard drive space is adopted repeatedly
With.
When in the hard drive space that the write of message group has been cleared, the hard drive space being cleared can be for writing
Message group, the hard drive space being written with message group is the most then disposed, and disposes and performs conveying after terminating, and empties the report of hard drive space
Literary composition group, constitutes the hard drive space being cleared, it is achieved the disposal of a message group again.
The setting means of number Y of described hard drive space is:
Step 1b: the process received, dispose, carry of message group is implemented to build equation, receives in i.e. setting the unit interval
It is invariant P by the number of message group, and to receiving the message that the bit stream that message group formed was disposed within the unit interval
The number of group is V, reduce for the intensity of information also have the impact of clutter make again to carry message need time-consuming standard
Difference is
Step 2b: obtain number Y of hard drive space with formula (1), (2) and (3):
Here, q, Z are all middle coefficient；
The described intensity for information reduce also have the impact of clutter make again to carry message need time-consuming standard
DifferenceNumerical value by conventional actual conditions realize amount to after and obtain.
The value of number Y of described hard drive space is 600,4 or 500.
And thus obtained embodiment is as follows:
The number receiving message group in setting the unit interval is invariant P, this invariant P=3*106/ L, wherein 3*106For
Receiving the figure place of message group in unit interval, L is the figure place of long message group, exists to receiving the bit stream that message group formed
The number disposed in unit interval is V=4.5*10 in the present embodiment6/ L, and the value of L can be according to the mark of actual message group
Standard obtains, the described intensity for information reduce also have the impact of clutter make again to carry message need time-consuming standard
DifferenceNumerical value by conventional actual conditions realize amount to after and obtain.
So above-mentioned numerical value being substituted into formula (1), (2) and (3), just can know that, the intensity of information reduces the least also clutter
Impact the most no small in the case of, the number of times again carried is the most more, and the quantity of such hard drive space is the most, and strong in information
In the case of degree reduction also has the impact of clutter to ignore, under the state that namely K (Z) is zero, just can obtain N is 122.7,
Namely need at least 123 hard drive spaces could meet the conveying of safety.
The manner has thoroughly overturned existing mode, replaces with the pattern of regulation write hard drive space repeatedly, real efficiently
Show and prevented the loss of message group from making the incorrect defect of information.
