Key failure detection method and device, computer equipment and storage medium Technical Field The invention relates to the technical field of key failure detection of a financial terminal encryption keyboard, in particular to a key failure detection method, a device, computer equipment and a storage medium. Background The financial device has no key device for encrypting the keyboard. The encryption keyboard has quite wide application, especially for unattended financial self-service equipment, and the key component is not used. At present, the design of the encryption keyboard has the advantages that the keyboard circuit is broken, the key function is lost, and the encryption keyboard cannot actively report errors. Since the encryption keyboard does not have the function of reporting that the keyboard fails and can not be used for pressing keys, and the keys of the encryption keyboard are directly oriented to a user, the probability of failure is high, and the probability of failure of one key can reach 99% of all failures, so that the situation that two keys fail and can not be used at the same time is not considered. Most of the financial self-service terminals are located at off-line positions, are remote in position, have high maintenance cost, and cannot be inspected every day. The encryption keyboard is used as a core component of the self-service equipment, and if the key failure of the encryption keyboard cannot be found in time, almost all service functions of the equipment cannot be used.
