Automation equipment is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and family, etc. So what do you know about automation equipment? The following is organized by me on what is automation equipment, I hope you like!
Overview of automation equipmentDefinition
Automation is specializing in intelligent automatic control, digital, networked controllers and sensors, research and development, production, sales of high-tech companies, its many functional modules, perfect embedded solutions can maximize to meet the individual needs of many users. The company's products have a variety of series of products to meet customer needs. The automation equipment consists of a vibrating disk with.
Meaning
Large sets of equipment in the automation system, also known as automation devices. It refers to the process in which a machine or device is operated or controlled automatically according to a specified program or instruction without human intervention. Therefore, automation is an important condition and significant sign of modernization of industry, agriculture, national defense and science and technology.
Troubleshooting of automation equipmentCheck all power sources, gas sources, hydraulic sources
Power sources, including the power supply for each piece of equipment and the workshop power electricity, that is, all the power sources that can be involved in the equipment.
Pneumatic sources, including air pressure sources required for pneumatic devices.
Hydraulic sources, including the operation of hydraulic pumps needed for hydraulic devices.
In 50% of the troubleshooting problems, basically the errors that occur are problems with the power supply, the air source, and the hydraulic source. For example, problems with the power supply, including the failure of the entire workshop power supply, such as low power supply power, insurance burned out, poor contact with the power plug, etc.; air or hydraulic pump is not turned on, the pneumatic triplex or duplex is not turned on, the hydraulic system in the relief valve or some pressure valves are not open and so on caused by. These are some of the most basic problems and are usually the most common ones.
Check for sensor position shifts
Due to negligence on the part of equipment maintenance personnel, it is possible that certain sensors may have been misplaced, such as not in place, sensor failure, sensitivity failure, etc. To frequently check the sensing position and sensitivity of the sensor, deviation in time to adjust, the sensor if broken, immediately replaced. Very often, if in the case of ensuring that the power supply, air and hydraulic source supply without error, more problems is the sensor failure. Especially the magnetic induction sensor, due to long-term use, it is likely that the internal overlap iron stick to each other, can not be separated, and there is a normally closed signal, which is the common problem of this type of sensor, can only be replaced. In addition, due to the vibration of the equipment, most of the sensors will be loosened in position after a long period of use, so it is necessary to frequently check whether the position of the sensor is correct and whether it is firmly fixed during routine maintenance.
Checking relays, flow control valves, pressure control valves
Relays, like magnetic inductive sensors, are subject to sticking laps after long periods of use, which prevents the electrical circuits from functioning correctly and requires replacement. In pneumatic or hydraulic systems, throttle valve openings and pressure regulator springs for pressure valves can also loosen or slip with the vibration of the equipment. These devices, like sensors, are components in equipment that require routine maintenance. Therefore, these devices must be carefully inspected during daily work.
Check electrical, pneumatic and hydraulic circuit connections
If none of the above three steps reveal any problems, then check all circuits. Look for breaks in the wires in the circuits, especially in the wire ducts to see if the wires have been cut by the ducts due to pulling. Check the air lines for damaging creases. Check for clogged hydraulic fluid lines.
In this step to check the circuit, use the necessary multimeter, set to the buzzer gear, check the circuit access. If the air line is badly creased, replace it immediately. The hydraulic fluid lines should be replaced as well.
After ensuring that the above steps are correct, the fault may appear in the controller, but never a program problem! First of all, do not be sure that the controller is destroyed, as long as there has not been a serious short-circuit, the controller has an internal short-circuit protection, general short-circuit will not burn the controller.
First, check if there is any high-frequency interference device near the controller. If there is, move it away immediately. If you are outdoors, high intensity lightning may also cause the controller to not work properly for a moment. At this time, first clear away all possible interference devices, and then restart the controller.
Secondly, if the reboot does not work, check if the controller wiring is loose and has poor contact.
Finally, if the wiring is correct. Determine whether it is a problem with the memory card of the PLC. Replace a new card, download the program, and check whether the previous memory card is faulty.
Application of automation technologyThe development of automation technology in the field of warehousing (including the main warehouse) can be divided into five stages: manual warehousing stage, mechanized warehousing stage, automated warehousing stage, integrated warehousing stage and intelligent automated warehousing stage. In the late 1990s and the 21st century, a number of years, intelligent automated warehousing will be the main direction of development of automation technology.
The first stage
Material transportation, storage, management and control mainly by manual realization, its real-time and intuitive is the obvious advantage. Artificial warehousing technology in the initial economic indicators of equipment investment also has superiority.
The second stage
Materials can be moved and handled by a variety of conveyor belts, industrial conveyor trucks, manipulators, cranes, stacker cranes and elevators, with shelving trays and removable shelves for storage of materials, through the manual operation of the mechanical access equipment, with limit switches, screw mechanical brakes and mechanical monitors, etc. to control the operation of the equipment. Mechanization to meet the speed, accuracy, height, weight, repeat access and handling requirements.
The third stage
is the stage of automated warehousing technology automation technology for warehousing technology and development played an important role in promoting. The late 1950s and 1960s, the successive development and adoption of automatic guided vehicle (AVG), automatic shelves, automatic access robots, automatic identification and automatic sorting systems. 70s and 80s, rotating body type shelves, mobile shelves, aisle stacker cranes and other handling equipment are added to the ranks of the automation, but this time it is only a local automation of the equipment and their respective applications independently, known as the "automation silo". Known as "automation island". With the development of computer technology, the focus shifts to the control and management of materials, requiring real-time, coordinated and integrated, between computers, data collection points, mechanical equipment between the controllers as well as their communication with the main computer can summarize the information in a timely manner, the warehouse computer timely records of ordering and arrival time, showing the amount of inventory, planners can easily make decisions about the supply, they know What is being produced, what goods to order, what time to send what goods, management personnel at any time to grasp the source of goods and demand. The application of information technology has become an important pillar of warehousing technology.
The fourth stage
is the stage of integrated automated warehousing technology in the late 70s and 80s, automation technology is increasingly used in the field of production and distribution, it is clear that ? Automation silos? needed to be integrated, and this led to the formation of ? Integrated systems? concept. In an integrated system, the organic collaboration of the entire system results in overall benefits and production resilience that greatly exceeds the sum of the independent benefits of each part. Integrated warehouse technology as a computer integrated manufacturing system (CIMS-Computer Integrated Manufacturing System) in the center of the material storage by people's attention. Although people in the 80's has paid attention to the system integration, but so far in our country has been built integrated warehousing system is not much. In the integrated system includes people, equipment and control systems, the three phases mentioned above is the basis.
