Industrial manufacturing field
Automobile manufacturing production line: In the stamping, welding, painting, assembly and other links of automobile production, PLC is responsible for controlling the movement of robots, the transportation of production lines, the coordinated work of equipment, etc. For example, the German SCHULER 6000KN large-scale automated stamping line introduced by Shanghai Volkswagen Automotive Co., Ltd. uses Siemens S5-115U programmable controller to independently control each press unit and mechanization unit, realizing the automated control of sheet stamping, conveying and other tasks, with an average of 6.7 times/minute.
Food and beverage packaging production line: On the beverage production line, PLC as the core controller combined with the expansion substation can automatically complete production tasks such as filling, capping, and labeling. On the pastry packaging production line, PLC can control the feeding, sealing, cutting and other operations of the packaging machine, and can also communicate with the quality inspection equipment to eliminate unqualified products.
Energy and power field
Substation automation control: In the substation of the oil field, the PLC all-in-one machine can monitor and control the operating status of the fully automatic intelligent maintenance-free DC screen in the substation in real time, such as the start-up of the rectifier module, the charging status display, the alarm information viewing, etc., to ensure the safe operation of the oil field power grid.
New energy power generation project: In the solar photovoltaic power station, the PLC can control the angle adjustment of the photovoltaic panel, the operation of the inverter, etc., to improve the power generation efficiency. In the wind farm, the PLC can monitor the operating status of the wind turbine, control the start and stop, speed, etc. of the wind turbine, and ensure the safe operation of the wind turbine.
Transportation field
Traffic signal control: In urban traffic management, the traffic lights at the intersection are controlled by the PLC control system to realize the timing control of the green lights in the north-south and east-west directions, and can dynamically adjust the working status of the traffic lights according to the traffic flow during peak hours, effectively reducing traffic congestion.
Intelligent elevator control: In elevators in multi-story buildings, PLC can respond to call requests instantly to minimize user waiting time. It also has fault detection function. Once an abnormality occurs, it will immediately stop and send an alarm signal to ensure passenger safety.
Other fields
Water treatment system: In the filtrate biochemical treatment of water treatment projects, PLC monitors water flow, temperature, concentration, pressure and other indicators, and automatically adjusts the dosing system, stirring device and filtration equipment according to the preset control strategy to ensure the stability and efficiency of water treatment.
Medical equipment control: In the operating room, the PLC all-in-one monitors the temperature and humidity information of the operating room in real time through sensors, and compares and adjusts according to the preset temperature and humidity range. In the fault monitoring and alarm system of medical equipment, the PLC all-in-one can monitor the operating status of the equipment in real time. When the parameters exceed the set threshold, an alarm signal will be issued and the fault information will be sent to the corresponding maintenance personnel.
