Sensor is connected with microcontroller.It is specifically configured outer to improve the monitoring accuracy of warm and humid degrees of data in round-the-clock monitoring process
The digital Temperature and Humidity integrated sensor put.The external benefit of digital Temperature and Humidity integrated sensor, one can be to avoid first device
Part long-term work heating makes temperature data higher, and two can be to avoid built-in making humidity detection inaccurate.
For example:Humiture integrated sensor can be using the SHT15 of Sensirion companies of Switzerland, and the chip is digital quantity
Output, long-time stability low in energy consumption, with brilliance, using IIC communication interfaces, SMD encapsulation, small volume, relative humidity measurement
Scope is 0~100%, and up to 0.03%, temperature measurement range -40~123 DEG C, resolution ratio is 0.1 DEG C, operating voltage to resolution ratio:
2.2V~3.6V, being capable of Relative Humidity Measuring, temperature data.According to its databook, DATA pins need to connect 10k Ω pull-up electricity
Resistance is connected to power supply DV33, and its connection circuit is as shown in Figure 6.
Humiture integrated sensor can also be using the Temperature Humidity Sensor of other models.
In fig. 2, the system also includes digital baroceptor, the digital baroceptor and microcontroller phase
Even.The present invention also using the pressure information around digital baroceptor detection transmission line of electricity and is sent to microcontroller and carries out
Storage.

Other series monolithics are compared, and can select STM32 processors.
On the basis of ground reference type monitoring method, power supply mode selection just can be with flexible and changeable.Electromagnetic environment is supervised online
Surveying device has the performance requirement of round-the-clock long time continuous working, therefore does not consider solar powered (unstable by weather or so
Calmly), laser powered sensor (technology is immature), and select most reliable storage battery power supply and mains supply to power.
Wherein, electromagnetic environment on-Line Monitor Device of the invention also includes shell, and shell is selected high-strength engineering plastic, adopted
It is assembled with back-off mode, and fixed using rubber screw, total interface is in lower end, meets all-weather outdoor use requirement.
In specific implementation process, acquisition station and two grades of sub- work stations, two grades of sub- work stations and the sub- work station of one-level, one-level
Communicated using optical fiber between sub- work station and central workstation.In order to adapt to the changeable environment in scene, oneself some nothings
The place of method wiring, the place that wire transmission cannot often be carried out, the present invention ensure that what data were transmitted by fiber optic communication
High efficiency, rapidity, reliability.
Fig. 8 is the date storage method flow of the real-time electromagnetic environment on-line monitoring system based on multi-stage distributed network
Figure.The data storage side of the real-time electromagnetic environment on-line monitoring system based on multi-stage distributed network of the invention as depicted
Method, including:
Each acquisition station first, is distributed a unique ID by central workstation;
Then, the electromagnetic environment monitor data markers transmission of same acquisition station come are same ID, and store to same and deposit
In storage space;Wherein, one memory space of each ID correspondences;
Finally, partitioned storage is carried out again to the electromagnetic environment monitor data in same memory space according to time range.
Further, same acquisition station is transmitted next electromagnetic environment monitor data storage a to form by central workstation
It is interior.
Further, central workstation by according to time range to the electromagnetic environment monitor data in same memory space again
Subregion is carried out, and then to form according to time zoning.
For example:For monitor database data storage size it is big the characteristics of, Monitoring Data first according to round-the-clock electromagnetic environment
Monitoring system ID points of table, then temporally range partition, in this, as the primitive rule of data storage, table name structure is for " T_ is complete
Weather electromagnetic environment monitoring system ID_ monitors season in time S ".
Data partition design facilitates background system application module to use parallel work-flow to monitor database, with abundant adjusting data
Storehouse computing resource, accelerates data retrieval and processing speed.Additionally, data partition design also mitigates the access pressure of database table
Power, by that according to data are accessed in time and season, single token can be recorded number and be limited within a hundred or so ten thousand grades, prevents because of Monitoring Data
The problem that database access performance drastically declines caused by expansion occurs.
Further, the method also includes caching electromagnetic environment monitor data by the way of data dictionary.This
Sample can improve the efficiency of real time data interaction.
When data history inquiry is monitored, six parameters can be transmitted to the search algorithm of Monitoring Data inquiry service,
Including stratification classification, level ID, inquiry starting and ending time, the page number and number of pages.
After Monitoring Data inquiry service receives |input paramete, the type according to level goes to determine the hierarchy of objectivies, Ran Hougen
The specific node in the hierarchy of objectivies is determined according to level ID.According to the node for determining, by way of infinite recursion in database
Obtain all round-the-clock electromagnetic environment monitoring systems for belonging to this node.
Meanwhile, Monitoring Data inquiry service can carry out season to the time interval represented by the starting and ending time of inquiry
Change is processed, and the season that time interval is divided into by representing in multiple seasons is gathered.
After round-the-clock electromagnetic environment monitoring system set and season set is obtained, Monitoring Data inquiry service is comprehensive by both
Round-the-clock electromagnetic environment monitoring system-season set is combined into, this set will be used by the parameter that finally enters as algorithm.
In order to realize monitoring the two-page separation function of the inquiry of historical data, Monitoring Data inquiry service is it needs to be determined that target database
The number of data of table, is used to determine the database table that needs are extracted during paging.
The wasting of resources for causing frequently is connected with database in order to save, request-response time is reduced, using in database
End is programmed to the function of realizing obtaining number of data.By writing corresponding storing process, incoming round-the-clock electromagnetism is only needed
Environmental monitoring system data-season set, database will be supervised according to the algorithm of storing process by round-the-clock electromagnetic environment
The number of data of the corresponding table of parameters of examining system data-season set is counted, after collecting to statistics,
Can return to the set of the number of data of required each tables of data.
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the invention, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need the various modifications made by paying creative work or deformation still within protection scope of the present invention.
