Specific embodiment
Embodiment 1
Monitoring system provided by the invention is as shown in Figure 1, the remote system is used for the operation shape to the transmission facility of distal end
State is monitored, and includes sensor in remote equipment, for detecting the target data in remote equipment, such as uses electric work
Rate, humidity, temperature, air pressure etc..It is number that sensor data obtained pass through digital-to-analogue conversion interface by analog-signal transitions again
Signal is re-fed into microprocessor and is analyzed and processed.
In addition, in systems further including having the first data storage and the second data storage.
What is stored in first data storage is the preset value that user pre-enters, and microprocessor is to the data acquired in real time
It is compared and analyzed with the preset value pre-entered, if the difference between real value and preset value has been more than specific threshold value
When, then it regards as system work and exception occurs, in this case, signal is passed sequentially through wireless communication module by microprocessor again
It transfers data in remote server.And if when the difference between real value and preset value is less than specific threshold value,
It is working properly to regard as system, microprocessor does not need to send the data to remote server at this time, thus makes remote equipment
Data when working properly do not need to occupy communication channel, the problem of having saved data resource, avoided corrupt data.
Second data storage is that the real time information for receiving above-mentioned microprocessor carries out storage backup, this part letter
Breath is for analysis when needing to transfer later.
In addition, being additionally provided with timing module in system, the temporal information before timing module at that time is real-time transmitted to micro- place
Device is managed, ensures that the data into microprocessor plus time tag, become time data in this way.
As shown in Fig. 2, in one embodiment, in the sensor of use including electricity consumption detection module and humidity inspection
Module is surveyed, the humidity being respectively used in the real-time electric power and equipment of detection remote equipment；As shown in figure 3, corresponding
The first data storage in preset value also include power use by time shearing amount data and humidity threshold, when microprocessor is by sensor
It after the data of middle acquisition stamp time tag, is then compared with preset value, if real value is less than preset electricity consumption number
According to the electricity consumption then represented at the remote equipment is normal；In addition, if humidity value has been more than threshold value in real time, then it is assumed that equipment
Location humidity is larger, it is understood that there may be higher leakage risk then needs the data being uploaded to server, and confession is subsequent
Respective handling.
If the sensor humidity data obtained for detecting humidity has been more than the safety value of setting, microprocessor
Issue the remote equipment where instruction is closed.
In order to further increase device security, humidity safety con-trol part is additionally provided in remote equipment.
As shown in figure 4, remote equipment is body structure, the top inside cabinet 1 is provided with horizontal positioned hydrophilic height
The lower section of molecular porous fibre pipe array 2, hydrophilic high mol porous fibre tube array 2 is provided with horizontal positioned hydrophobic polymeric
Porous fibre tube array 3.Hydrophilic high mol porous fibre tube array 2 is by more hydrophilic high-molecular porous fibers parallel rows
It arranges, water can be referred generally to using the polymeric hollow fibre pipe of conventional surface hydrophilic modification, hydrophily described here
Polymer surfaces contact angle less than 60 °, and hydrophobic polymeric porous fibre tube array 3 is by more hydrophilic macromolecules
Porous fibre is arranged in parallel to be formed, can be using the polymeric hollow fibre of conventional surface hydrophobicity modified (or unmodified)
Pipe, hydrophobicity described here refer generally to water and are greater than 120 ° in the contact angle of polymer surfaces.Parallel between hollow fiber conduit
It, can there are a small amount of gaps, such as 1mm between each other when column.
Have above remote equipment cabinet under water to when leaking out, is that can fall in hydrophilic high mol porous fibre tube array first
On 2, since its surface is hydrophily, water can make water will not be to whereabouts, but after being unfolded faster in the rapid drawout in its surface
Evaporation avoids water droplet and falls in the equipment of lower section.
But if hydrophilic high mol porous fibre tube array 2 cannot be sprawled and be evaporated compared with flood when overboard amount is larger
When amount, water droplet can further be fallen on the hydrophobic polymeric porous fibre tube array 3 of lower section, and it is hydrophobic for being due to its surface
Property, therefore water droplet can be formed on its surface drops, surface can accommodate enough water droplets, prevent more water droplets downward
It falls in electric component.
If water further increases, it is possible to cause the also unbearable foot of hydrophobic polymeric porous fibre tube array 3
Enough water droplets simultaneously will lead to it is possible that water droplet can be due to overweight and to when falling.Therefore, hydrophobic polymeric porous fibre tube array 3
Both ends are to be set on motion bar 4, and motion bar 4 is set on pressure sensor 5；Therefore, when hydrophobic polymeric porous fibre
When water droplet amount on pipe array 3 reaches a certain level, when being more than the threshold value set on pressure sensor 5, microprocessor is automatic
The power supply of remote equipment is closed, the security risk that excessive leak may cause is avoided.In addition, hydrophilic high mol porous fibre
The both ends of pipe array 2 and hydrophobic polymeric porous fibre tube array 3 pass through the first hose 6, the second hose 7 and gas conveying respectively
Device 8 be connected is connected into closed loop, air transporting arrangement 8 is evacuated from hydrophilic high mol porous fibre tube array 2, at the same to dredge
Gas transmission in the high-molecular porous fibre pipe array 3 of water can be with since gas is extracted out from hydrophilic high mol porous fibre tube array 2
The water for opening 2 surface spreading of hydrophilic high mol porous fibre tube array is taken away from the surface of porous fibre by air, quickly real
Now water layer is removed；And when air transporting arrangement 8 is supplied gas into hydrophobic polymeric porous fibre tube array 3, gas is from its table
It is discharged in the porous structure of face, further increases contact angle when its surface and water drop contact, water droplet is made more to be not easy to sprawl,
The wetability for reducing water droplet keeps the weight of the easy water in its surface bigger.
