s101: a user inputs a user name and a password on a login interface;
s102: after the user name is compared with the user name database, whether the current user name exists in the user name database or not is searched according to the user name input by the user, and if yes, the next step is carried out; if not, ending;
s103: after the password is compared with the password database, whether the password of the corresponding user in the password database is the same as the password of the corresponding user is searched according to the password input by the user, and if the password is the same as the password, the login is successful; for example: when a common user logs in, if a correct common user name and a correct password are input, the common user logs in, and the content related to the authority of the common user is displayed;
when the equipment maintainer logs in, if the correct equipment maintainer user name and password are input, the equipment maintainer logs in, and the content related to the authority of the equipment maintainer is displayed;
when a system administrator logs in, if a correct system administrator user name and a correct system administrator password are input, the system administrator logs in, and the content related to the authority of the system administrator is displayed.

In practical application, under the condition that a common user forgets a password, if a correct common user name and a dynamic password with a timestamp are input, the common user can log in, and then the password can be reset; under the condition that the equipment maintainer forgets the password, if the correct equipment maintainer username and the dynamic password with the timestamp are input, the equipment maintainer can log in, and then the password resetting operation can be carried out; under the condition that a system administrator forgets a password, if a correct system administrator user name and a dynamic password with a time stamp are input, the login of the system administrator can be completed, and then the password resetting operation can be carried out.
The verification method for the user name part comprises the following steps: the user name part is verified by comparing with a user name database, namely whether the current user name part exists in the user name database is searched, and if the current user name part does not exist in the user name database, login is failed; if the username portion exists, then the timestamp portion is verified.
The verification method for the time stamp part is as follows:
s20201: acquiring current equipment time, and calculating a current timestamp through an asymmetric encryption algorithm;
s20202: comparing the timestamp part with the current timestamp, and if the timestamp part is the same as the current timestamp part, successfully logging in; if not, the login fails.
Based on the above, the control of the authority is realized through the static password authentication and the dynamic password authentication, and the login authentication of the user is completed.
