2020 was a difficult period for all countries of the world. Pandemic world the economic crisis has had a serious impact on the economies of most countries. The state and people of Azerbaijan, in spite of all the economic and social damage and the material damage caused by the war, shielded the aggression against them and launched a counter-operation to liberate the lands. If we pay attention to the main parameters of the economic potential of the occupied territories, we can see that Karabakh and its environs Lachin, Kalbajar, Gubadli, Zangilan, Jabrayil, Aghdam, Fuzuli were occupied by Armenia in 1989 and 1993, and the infrastructure of the regions was destroyed. For this reason, future restoration work began with the construction of general infrastructure and primary settlements, and at a later stage should be transferred to economic development projects. Our liberated territories cover two economic geographycal regions. Kalbajar-Lachin and Upper Karabakh. During the occupation of our lands, all buildings were destroyed, forests, reserves, monuments, parks, museums were destroyed. In addition, industrial and agricultural areas, power lines, mineral deposits, transport hubs were severely damaged. After a historic victory in 2020, which resulted in the liberation of the occupied territories of our country, Azerbaijan enters a new stage. The geography of reviving Karabakh must be studied by every citizen. There is a need to restore the landscape of this areas, mineral deposits, industry, electrical systems, roads, tourists sites Key words: Nagorno Karabakh, Natural landscape, tourism, economy, mineral waters, industry, minerals, electric power, priority, great return

Based on the fact that a large number of timing controllers are needed in the applications like sequential logic control and programmable controller, this paper proposed a PLC timer system based on ARM+FPGA, in which ARM is used to execute user program while FPGA is used for timer operation in parallel. The FPGA timer module consists of timer controller, timer dynamic parameters and soft contact state register, the timer controller carries out counter operation for timing unit every 1ms, then results from timing operation would be saved in timer parameter list of a dual port RAM, when controller commands need to be executed via PLC, the timer will be used as a regular memory unit for W/R operation, thus no executing time of PLC program would be spared basically, which can well meet the system requirements where large number of controllers are needed. Simultaneously, principles of system composition, timing operation control and timing operation flow are all introduced followed by which a field test is also carried out for testament of the designed timer system.

Aiming to solve the problems of long execution count and low frequency of counter which has been largely used in various electronic facilities and PLCs, unlike traditional design that utilize embedded microprocessor software for count operation, this paper proposed a parallel operated counter based on ARM+FPGA. The FPGA counter module consists of count controller, SDRAM dynamic parameter and soft contact state register, the count controller carries out counter operation for timing unit every 1ms, then results from count operation would be saved in counter parameter list of a dual port RAM, when controller commands need to be executed via ARM, the counter will be used as a regular memory unit for W/R operation, thus no executing time would be spared basically, which can well meet the system requirements where large number of controllers are needed. Simultaneously, principles of system composition, count operation control and count operation flow are all introduced followed by which a field test is also carried out for testament of the designed counter system.
