Abstract


With China's rapid economic development , the logistics industry has become one of the state plan for the development of ten key industries , the development of the port is the most important industry . Among them, the proportion of container loading and unloading operation volume of the total port is the highest , and therefore requires a large amount of container handling equipment - Reachstackers . The research object Department of the domestic large-scale research and development Reachstackers , Reachstackers control system is the key core technology . 45t Reachstackers the complexity of the control system , security , high stability requirements , development difficulties , China has long been Reachstackers control system market monopoly of foreign manufacturers . In order to break this unfavorable situation , the country urgently needed to develop large Reachstackers control system owns the the national independent intellectual property rights and market competitiveness . The the 45t Reachstackers sports safety control system implemented by moment balance theory the container automatic weighing and anti- overturning control , thus ensuring the safety of the vehicle during operation to eliminate dangerous situations lifting overloading and bodywork overturning . Based on the vehicle CAN bus technology , the stacker control system data transmission security , real-time and reliability . The control system has a user-friendly man-machine interface , visual display and user-friendly operation of the control system data . MATLAB programming language to build the mathematical model Reachstackers , the successful verification system weighing , load and anti- overturning control algorithm correctness . Successful due to the use of a reasonable and effective data structure and program flow of sports safety control system software development , use of PC applications for the control system to add more practical extension function . Hanging by 45t container front sports safety control system debugging and prolonged industrial operation , control system CAN communication module , weighing module , load the table , anti- overturning control , man-machine interface and the host computer applications have been a large number of the test of practice. All results show that sports safety control system is working to achieve similar foreign products , performance indicators , with a strong technical advantage and market competitiveness .
