Ring gate of Ahai hydropower Station is known to the highest ring gate in the world. In this paper, it is calculated to the driving loads of the Ahai ring gate by six hydraulic servomotors during a closure without automatic control (i.e. in case of a breakdown of the electrical control system), analyzed the behavior of the operating system of the ring gate closure in balanced conditions with the permanent loads, and finally shown to how the six servomotors are synchronized on the basis of the driving loads. There are proved to The feasibility and the credibility of this system of ring gate to a case by using ANSYS.

Ring gate of Ahai hydropower Station is known to the highest ring gate in the world. In this paper, it is calculated to the driving loads of the Ahai ring gate by six hydraulic servomotors during a closure without automatic control (i.e. in case of a breakdown of the electrical control system), analyzed the behavior of the operating system of the ring gate closure with the water discharge and closure with three wicket gates not synchronized (i.e. three wicket gates remained accidentally in open position), and finally shown to how the 6 servomotors are synchronized on the basis of the driving loads. There are proved to The feasibility and the credibility of this system of ring gate by using ANSYS to a case.

Operation Control

The brake release electrical control board is a very important element of the elevator rescue operation control system. The brake release board provides a power supply to operate an elevator brake by a battery in rescue operation mode to allow a motion of a car until the next floor level to release any passengers. The brake release board has some buttons to operate the car and some LED’s to indicate the state of running. There are also some parameters in the board to adjust the operation.

Along with the development of the automatic control the world of technology at this present time, making the control system automatically helps a person to ease his work. A lot out there who already using a wide variety of automatically working systems. Automatic control system now can make various kinds of variety such as controlling hydraulic system automatically to avoid flooding. This control is done using an Arduino microcontroller and ultrasonic sensors, which the microcontroller as input media program that will be in the process and ultrasonic sensors to measure the distance of the water level. The method used to design the hydraulic system uses a flowchart, The hardware used includes Arduino Uno, Ultrasonic Sensors, Motor-drive (DC), Lamp LED, buzzer and several other electronic devices. The design of the hardware using the Arduino Uno as a medium to instill the program and software design were performed using of Arduino . Automatic control is intended to avoid damage to the goods caused by flooding.

The introduction of information and digital technologies that support and support all technological processes in the field is an urgent need for the development and implementation of such technology. An organisationally complex and financially intensive project is necessary because of the wide variety of economic entities that differ in the size of production, forms of ownership and socio-economic conditions of production. Automated information control system for mobile units agricultural enterprise provides those-Niko-economic performance, optimum capacity utilization through the use of timely and reliable information on technology. Machine and tractor aggregates are appertained as control objects with variable structure, which is explained by possibility of the system formation from tractor or field machines mobile units with various purposes: tillable, cultivatable, sowing, harvesting and etc. This MTA feature was determined creation of digital control systems of two groups of automatic control and management of the basic energy and operational parameters: tractors, machines and vehicles as part of MTA. To the first group are appertained the automatic control system of tractor motor component loading, motion speed, frictional sliding. To the second group – automatic regulation system of operating depth, seed rate, treatment of liquid combined fertilizers and crop protection agents, filling and driving of various MTA. Novelty of researches consists in methodology of the organization of the centralized control and management of various technological processes at carrying out field works.
