The Automatic Control Principle Of Concrete Self Loading Mixer Truck
The automatic control principle of concrete self loading mixer truck mainly relies on advanced control systems and sensor technology. The following is a detailed explanation of its automatic control principle.
1. Core Control System
The automatic control core of concrete self loading mixer trucks is usually based on programmable logic controllers (PLCs) or similar embedded control systems. These systems have high reliability and flexibility, and can precisely control the various functions of the mixer truck according to preset programs and parameters.
2. Sensor Technology
In order to achieve automatic control, the concrete self loading mixer truck is equipped with various sensors, including but not limited to:
Position sensor: used to detect the position and status of components such as mixing arms and hoppers, ensuring that they are working at the correct position and angle.
Weight sensor: installed on the hopper or mixing drum, used to monitor the weight of materials in real time, thereby accurately controlling the amount of materials to be dispensed.
Temperature sensor: used to monitor the temperature of materials inside the mixing drum, to prevent the quality of concrete from being affected by high or low temperature.
3. Automatic Control Process
Startup and initialization: After the mixer truck is started, the control system will perform initialization operations, check the status of each sensor and actuator, and ensure that they are in normal working condition.
Material feeding: According to the preset program and parameters, the control system will accurately control the opening and closing of the hopper, as well as the telescopic action of the mixing arm, in order to achieve automatic feeding and mixing of materials.
Mixing process control: During the mixing process, the control system will accurately control the rotation speed and direction of the mixing arm based on the present mixing time and speed parameters to ensure that the material is thoroughly mixed and stirred.
Fault detection and alarm: The control system also has fault detection and alarm functions. When sensor failure, actuator failure, or other abnormal situations are detected, the system will immediately issue an alarm signal and take corresponding protective measures to prevent the fault from further expanding.
Shutdown and unloading: After the mixing process is completed, the control system will control the mixing arm to stop rotating and open the unloading port to discharge the mixed concrete. At the same time, the system will also clean and maintain the mixing drum to ensure that it can work properly for the next use.
4. Advantages of Automation
The automatic control principle of concrete self feeding mixer truck brings the following significant advantages.
Improving production efficiency
Automated control enables the precise and rapid execution of various functions of the mixer truck, greatly improving production efficiency.
Reduce labor intensity
Operators can achieve comprehensive control of the mixer truck through the control panel or remote control, without the need for heavy manual operations.
Improving product quality
Automated control can accurately control parameters such as materials dosage, mixing time, and speed, ensuring stable and reliable quality of concrete.
Enhance safety
Automated control can monitor the various parameters and status of the mixer truck in real time, detect and deal with potential safety hazards in a timely manner, and ensure the safety of operators and equipment.
In summary, the automatic control principle of the concrete self loading mixer truck is based on advanced control systems and sensor technology. By precisely controlling various functions and parameters, efficient, stable and safe concrete mixing operations have been achieved.
