Fault tolerance method for financial self-service device

Abstract

The present invention discloses a fault tolerance method for a financial self-service device. The method comprises: sending a start instruction to all motors associated with an application service; detecting, one by one in a preset sequence, whether each motor is successfully started; and if a motor with a start failure is detected and the number of times of restarting of the motor with the start failure is less than a preset number, restarting the motor with the start failure. According to the fault tolerance method for the financial self-service device provided by the present invention, by detecting whether the motor is successfully started and restarting the motor with the start failure, use of a method of software fault tolerance reduces the probability of motor failure in a usage process of the financial self-service device, so as to provide better experience for customers; no external components are needed for implementation, so that an outage rate is reduced, and the maintenance cost is reduced; and the method is simple in control, good in program flexibility and little in system resource occupation.

Description

technical field [0001] The invention relates to the technical field of software fault tolerance, in particular to a fault tolerance method for financial self-service equipment. Background technique [0002] In the self-service equipment of financial institutions, the motor is a very critical and important component. Taking an ATM machine as an example, usually an ATM contains multiple types of motors (such as brushless motors, brushed motors, stepping motors, etc.), and There may be more than one of each type of motor. [0003] During the production of motors, due to factors such as processing technology, processing accuracy or materials used, the performance of the production motors may not fully meet the level required by the theoretical design, and may be affected by assembly accuracy during the assembly process, and may be different in different regions. Affected by different ambient temperatures, etc., therefore, the motor applied to the ATM machine will have a certain...

This processing method may bring poor user experience to customers. Once the transaction is judged to fail due to motor failure during the transaction process, some customers may find it difficult to accept it, and this processing method also directly increases the failure rate of the machine.
