The clear code signal is respectively sent to the password computing unit 72 and the switch 3 as a clear code carrier; the password computing unit 72 can be internally provided with a specific computing algorithm, can convert the received plain code into a first cipher code through computing after receiving the plain code, generates a first cipher code signal, and sends the first cipher code serving as a carrier of the first cipher code to the cipher code receiving unit 71; wherein the first combination is a decimal string having a fixed length. The password receiving unit 71 can make an input judgment: with the first password received from the password calculation unit 72 as a reference, it is determined whether the same character string as the first password is received, that is, whether the input password is correct. The display unit 6 is specifically a human-computer interaction interface arranged on the device, and both the clear code signal generated by the clear code generation unit 73 and the first secret code signal received by the secret code receiving unit 71 can be transmitted to the display unit 6 through the switch 3, and can be selectively displayed in the display unit 6 in the form of the clear code and the first secret code. When the equipment is in a debugging stage, the plain code and the first cipher can be displayed in the display unit 6, after the equipment is subjected to relevant maintenance, a worker can directly input the first cipher in the display unit 6, then a first cipher signal is generated in the display unit 6 and is transmitted to the cipher receiving unit 71, the input judgment result of the cipher receiving unit 71 is yes, namely the input cipher is correct, the communication connection between the operation parameter library 1 and the switch 3 is further switched on, then relevant parameters in the operation parameter library 1 are called through the display unit 6 and are cleared, and the initialization operation of the relevant parameters is completed. After equipment debugging is finished, only a plain code is displayed and a first secret code is hidden in a display unit 6 before the equipment leaves a factory, therefore, after the equipment leaves the factory and needs maintenance in the using process of a client, after-sales personnel can carry a password calculator 8 to the client, after related maintenance is finished, the password calculator 8 is in communication connection with a password calculation unit 72 and in input connection with the display unit 6, so that a calculation method in the password calculation unit 72 is called, then the plain code displayed in the display unit 6 is input into the password calculator 8, and the plain code is converted into a second secret code through calculation of the plain code calculator 8; the second cipher is a fixed-length decimal character string, and since the cipher calculator 8 is associated with the cipher calculation unit 72 and has the same calculation method, the value of the second cipher is equal to that of the first cipher; the after-sales personnel inputs the generated second password into the display unit 6, generates a second password signal containing the second password in the display unit 6, sends the second password signal to the password receiving unit 71, and performs input judgment in the password receiving unit 71, and because the first password is the same as the second password, the input judgment result is yes, namely, the password is input into the password receiving unit 71 through the display unit 6, the communication connection between the operation parameter library 1 and the switch 3 is opened, and then the after-sales personnel calls the relevant parameters in the operation parameter library 1 through the display unit 6 and clears the relevant parameters to complete the initialization operation of the relevant parameters. In summary, no matter the device is debugged before or used by a customer after the device is shipped, the password is input to the password receiving unit 71 through the display unit 6, so as to connect the communication connection between the operation parameter library 1 and the switch 3, and then the relevant parameter initialization operation is performed, so that the device manufacturer can perform point-to-point maintenance on the device after the device is shipped, grasp the maintenance data of the whole life cycle of the device after the device is shipped, and facilitate the control of the use condition of the device.

When the communication connection between the password calculator 8 and the password calculation unit 72 is failed so that the password calculator 8 cannot work normally, after-sales personnel can inform an equipment manufacturer by telephone, the equipment manufacturer informs that a password needs to be input or the equipment manufacturer calls data of an operation parameter library from the data server 51, and performs initialization operation on the data in the operation parameter library 1, and for achieving the purpose, as shown in fig. 6, a plain code signal generated by the plain code generation unit 73 and a first secret code signal received by the secret code receiving unit 71 can also be transmitted to the data server 51 through the switch 3 and the communication unit 4; when the communication connection between the password calculator 8 and the password calculation unit 72 is failed, the data server 51 transmits the first password signal to the password receiving unit 71 through the communication unit 4 and the switch 3 in sequence; since the first password input by the password calculation unit has already been received in the password receiving unit 71, when the first password sent by the data server 51 is received again, the input judgment result is that the communication connection between the operating parameter library 1 and the switch 3 is connected; the operator can then directly retrieve and clear the relevant data in the operating parameter library 1 from the data server 51 at the factory, or inform the after-sales personnel that the correct password has been entered and that the initialization of the relevant parameters can be started, and then retrieve and clear the relevant data in the operating parameter 1 through the display unit 6.
