The main directions of economic and social development of the Republic is the characteristic intensify agricultural production. A powerful tool for the intensification of agricultural production in the face of his specialization is irrigation. In areas of insufficient moistening (especially typical for mountainous areas) irrigation is one of the decisive factors of the cultivation of high and stable yields of agricultural crops. The purpose of the study: For this purpose, requires the development of new technical solutions and the introduction of automated systems of low irrigation of crops eligible for Ecology and environment Wednesday to improve their environmental condition of irrigated lands, reduce water consumption per unit products and increase the productivity of those or other crops on irrigated field.
Irrigated soil in Azerbaijan covers 1.45 thousand hectares. It is believed that factors directly affecting the fascination with crop yields and productivity in this area per hectare of arable land and agricultural land at minimal cost, labor and funds also apply automation application. Automated irrigation increases the effectiveness of all factors intensifying: Chemistry, integrated mechanization, intensive technology upgrade, etc. It allows you to create a large zone of guaranteed crop production.
Objects of Study: The object of the study is to explore and create the correct methods for regulating water use and supply of plants by means of irrigation in regardless of weather conditions. To this end, we have developed and introduced into production design systems of automated management systems for irrigation of low- Micro-tailings of self-oscillating action, successfully passing the resource tested test on vydelochnyh soils under Orchard, Lip Hachmasskoj area on the foothills of the Mountain above level at an altitude of 600 meters sea with sloping terrain 0.02. (see the concept of impulse systems rain avtokolebatelnogo actions with automated controls Figure1. Construction and functional description of the CMO AY so for operational control of the weather conditions in the region needed to meet the challenges of planning and operational irrigation management crop fields at the local gidrometeopunkte are set measurement sensors with probes for telemetric measurement taking the readings the main parameters:
a) Wind speed-V analog signal (Titus) with period recording of parameter values in the cycle of 30 minutes
b) Air temperature-tv, analog signal (Titus) with period recording of parameter values in the cycle 30 min.
c) Air humidity-Wb, analog signal (Titus) with period recording of parameter values in the cycle of 30 minutes.
Figure 1: schematic diagram of impulse systems rain avtokolebatelnogo actions with automated controls.
The reading parameter values in the telemetric heskom code is done smart object controller (to) established in paragraph transformer via a radio channel which communicates with sensorsconverters.
Ko otschitannye telemetry signals codes undergo preliminary processing, homogenization and written to main memory, which stores prior to their taking the readings the communications controller (CC) that is installed in the premises of the operational control technology process (ASMO)-operator. For monitoring and control of electricity supply facilities and power consumption accounting to ASMO transform point (TP) (see structural concept of APCS for irrigation) installed transmitters:
i. voltage measuring input) in TP-U (analog signal (Titus)
ii. measurement load consumers-I U (analog signal (Titus)
iii. electricity metering)-Wh (discrete signal integrated-TII
iv. control switch settings (enable-disable consumers)-SS (discrete signal position SHH).
Report parameter values in the telemetricheskom code is performed by intelligent object controller (KO) of local wire and after their initial processing and averaging is written into RAM. For monitoring and control technological process of abstraction, clarifiers (wastewater treatment plant) and pumping stations (devices increase the water pressure in the pipes) installed transmitters listed in structurally-functional schema:
a. water turbidity in the ponds-m (analog signal loop to read Titus, 30 min)
b. water level in chambers-ponds-n (analog signal TITUS, read in a loop 30 min); in water pressure-r installed on discharge pumps, modular and distribution reservoirs (analog signal TITUS, read in a loop 30 min)
c. load dimensions electric motors-I (analog signal TITUS, read in a loop 30 min)
d. provisions of valves-PZ (discrete signal SHH, readable in cycle 1)
e. power switches) Regulations-VP (discrete signal SHH, readable in cycle 1)
f. alarms-AU (discrete signal TCA, readable in cycle 1 with priority)
g. water metering pumps and supplied in the distribution pipeline-Q (integrated signal TII, processed in the cycle of 1:00).
Soil monitoring and process control of irrigation is carried out according to the specific fields of irrigation based on measurements of the agrophysical and technological parameter sensorsconverters:
I. soil moisture VLP-(analog signal TITUS with a 30 min cycle)
II. evaporation from soil surfaces-Exec (analog signal TITUS with a 30 min cycle);
III. soil temperature) t°-(analog signal TITUS with a 30 min cycle)
IV. water consumption irrigation on distribution pipeline plot-Q-(integrated signal with a 30 min cycle)
V. inclusion of the GKS discrete signal readable in a cycle of 30 s
VI. position switching valves (discrete signal read SHH 30 c).
VII. Report telemetricheskom signal code is performed by intelligent object field radio communications controller and after their initial processing and averaging processor is written into RAM.
Recorded in the memory controller objects (to) data are programmatically by radio and wire communications controller (CC) connected to your computer Tower (PD) (see circuit diagram system intensity of irrigation and automated controls), according to the specified rules and written in his memory in the structure of the telemetry files (see information provision). Computer exchange programs plays the data from RAM to the COP, transcode them and writes into the database from which displays them in real time on the display mnemoshemah, and after linearized and averaging the data on their codes programmatically are recorded in the cumulative base structure which provides information, and this generates a data bank complex tasks ASMO [1-3].
Before writing to the Bank data stream measurement data analyzed by specified algorithms and when the results of the analysis, with deviations from the values specified in the rules of the installations is operational control (OBU) process. Operating base control programmatically at the specified in the rules of the cycle is counted by the management module on technology directions and if there are deviations in the data records for this activity generates a control signal to the appropriate the executive body.
A. Data Interchange on The Work of the System of Irrigation is Carried Out Via the Internet: To do this, you must connect through a computer modem to the telephone network and earn the right to Internet access through an Internet service provider. This requirement applies to each Subscriber. If these conditions are met, the computer ‘ The Center can communicate with computers on the sections of the irrigation districts of Azerbaijan and other States.

When measurements of parameters, it is necessary to take into account the dispersion of available measured values. The value of the parameter, which can be taken for the actual probability of 0.8, is determined by the number of repetitions of measurements is defined by the formula:
