An automatic repair method for driving peripheral communication

Abstract

The invention discloses an automatic repairing method for driving peripheral device communication, comprising the following steps: firstly, all module drivers use a common device base class, which can intelligently identify different modules sharing a port, so as to realize shared management and rapid synchronization of handles; , based on the inheritance feature of object-oriented development based on the driver architecture, through the STL standard template library, the general functions are implemented by the base class, and the subclasses are used directly; 3. After the communication is abnormal, set the communication exception flag of itself and the shared port module; 4. Try to repair , through the shared device base class, the composite module of itself and the shared port only needs to be repaired once; 5. If the repair is successful, set the connection success flag, and then set the shared port module connection success flag, and feedback and repair it through the base class; If the repair fails, the repair is directly terminated, and the repair is attempted after re-detection; the present invention improves the repair efficiency, improves the code reuse rate, and facilitates management and control.

Description

technical field [0001] The invention relates to an automatic repair method for driving peripheral communication, belonging to the technical field of self-service equipment. Background technique [0002] Self-service equipment is generally connected to various types and models of hardware modules, and communication abnormalities will inevitably occur during use. However, in order to ensure the continued use of the equipment, a flexible and fast recovery mechanism for disconnection and reconnection is required to improve equipment operation. Efficiency and reduce human operating costs. [0003] The general method uses a separate module to reset or turn off the device when the device is abnormal, try to re-establish the connection, and each module maintains and repairs by itself, but there are many shortcomings: For example, the code reuse rate is low, and the same function needs to be implemented separately for each module; For composite devices, such as two-in-one, three-in-...

AI Technical Summary

Problems solved by technology

[0003] The general method uses a separate module to reset or close and open when the device is abnormal, and try to re-establish the connection. Each module maintains and repairs itself, but there are many shortcomings: such as the code reuse rate is low, and the same function needs to be implemented separately by each module; For composite devices, such as 2-in-1, 3-in-1, etc., the device port is shared, and repeated repairs are performed during runtime, which is inefficient
