HOPE-II Mitsubishi passenger lift adopts dual-core 32-bit CPU, 32-bit high-speed digital-signal processor, high performance chips with over ten thousand circuits which are able to compile logic gate arrays on-site in large scale, thus taking a giant stride in strengthening its ability to process and respond to the system data, to the extent of qualitative improvement. Besides, Mitsubishi climbing elevator employs world leading SMT(Surface Mount Technology )technology, to realize full digital control in its true meaning, so that the system control performance and reliability reach the world advanced level.
Meanwhile, the sub-systems of Mitsubishi big capacity elevators, such as lift car instruction controller, in-car floor indicator, door-operator controller, buttons and floor indicator on each landing, etc., use respectively independent micro-processors, resulting in more efficiency and accuracy of the controlling. Moreover, the connection between sub-systems needs only two lines, greatly raising the reliability and flexibility of the system, and reducing the cost of maintenance.
Through independent research and development, SMEC craftily employs world leading technology to the design of passenger lift. HOPE-II passenger lift adopts the advanced CANBUS digital network control technology based on the field bus, to enhance its reliability and increase the transmit rate substantially, and at the same time to make digital transmission more flexible and prompt.
Due to the intelligent power module(IPM), the quick protection circuits will provide more effective protection for the power modules, further promoting the reliability of the driving system. In addition, direct-inserting connection is employed to link the driving control circuit E1 board and IPM module, so as to greatly strengthen the anti-interference ability of the system.
Mitsubishi passenger lift uses a 32-bit digital signal processor（DSP）to control the variable-frequency and variable-voltage driven door operator without link-arm, so that the closing moment can be automatically regulated according to the different door resistances of each landing, thus passenger lift door opening/closing even more steady, sensitive and safe, and leaving a feeling of cordiality and security to passengers. Further more, the application of this new technique can not only save more energy, but also offer ever easier maintenance and more reliable performance.
Each set of Mitsubishi passenger lift must pass through a real-time and accurate load test, and according to the feedback, provide adequate pre-control moment in the start-up, which realizes every light and steady start-up. Even during traveling, continuous adjustment of the moment control guarantees the passenger lift in steady operation all the time.
