8. a kind of detection and tele-control system based on transformation cabinet according to claim 7, which is characterized in that described aobvious
Display screen is liquid crystal display, and the indicator light is LED light, and the corresponding relay of the indicator light is attracted, and the indicator light is bright, if
The relay release corresponding LED light is extinguished.
9. a kind of detection and tele-control system based on transformation cabinet according to claim 8, which is characterized in that described to deposit
The variation that store the temperature, humidity and output voltage size of each transformation cabinet in reservoir, will be deposited by the central processing unit
Storage information is fabricated to line chart and shows on the display screen, more intuitive to find out variation tendency, adopts to different transformation cabinets
Take different precautionary measures.
10. a kind of detection and long-range control method based on transformation cabinet, based on described in any one of claim 1-9 one
The step of detection and tele-control system of the kind based on transformation cabinet, the long-range detection of the transformation cabinet and long-range control method, is such as
Under:
The detection method of transformation cabinet:
Step (a): by the temperature sensor, humidity sensor and voltage detecting circuit to temperature, the humidity in transformation cabinet
It is detected with output voltage and the information that will test is transmitted to the one-chip computer module；
Step (b): the analog signal that the single-chip microcontroller will test is converted to digital signal by the analog-digital converter and passes
It is delivered to the communication module；
Step (c): the communication module will test signal by wireless network and be transmitted to the server；
Step (d): the server stores the signal received in the memory, and shows on the display screen；
The long-range control method of transformation cabinet:
Step (1): the temperature and humidity that the central processing unit will test compared with, enters step 2 and step with preset value
3；
Step (2): the central processing unit is by comparing judging whether temperature and humidity are greater than preset value, if no more than step is entered
Rapid 4, if the temperature detected and humidity are greater than preset value, the central processing unit is by the communication module to the single-chip microcontroller
Module sends instruction, and the one-chip computer module controls the work of the exhaust fan and dehumidifier and enters step 5；
Step (3): the central processing unit judges to detect voltage value whether within the scope of qualified voltage, if so, entering step
4, it is instructed if it is not, the central processing unit is sent by the communication module to the one-chip computer module, the single-chip microcontroller mould
Block controls the relay group release, the alarm equipment alarm, and the corresponding indicator light extinguishes and shows on the display screen
The position of the transformation cabinet to go wrong；
Step (4): the detection module continues to detect transformation cabinet；
Step (5): the temperature sensor and humidity sensor continue to test the temperature and humidity in transformation cabinet, and are transmitted to institute
It states server and enters step 2.
