Financial equipment market of China is in the domination of foreign manufacturers monopoly for a long time, no matter from the state’s financial information security level, market development and financial equipment core technology accumulation, etc., Research and development the core technology of the dispenser is imperative.The article presents a method of electronic control design of dispenser module based on embedded system. The dispenser module control system uses STM32F103 enhanced micro-controller as the main control chip, through abundant STM32F103 powerful peripheral drive every functional unit module, and acquire the status information. The article expounds each function module in detail in accordance with the requirements of the system.The article expounds the execution parts including the electromagnet, the working principle of stepper motor and dc motor as well as the selection of parameters and driving circuit; This article introduces the working principle of the photo sensor and drive circuit and the adaptive adjustment method,The storage unit, communication unit and display unit and debug unit. This article introduces the method of PCB printed circuit board design. For electromagnetic compatibility problem of the electric control system from two aspects of principle of design and PCB design gives the detailed design specification and the attention should be paid to the problem of circuit design and the design method. |
