Technology and life: starting with solar cars

Chapter 155

The system administrator means the person with the highest authority, and the classification of various levels of the system is realized through the user classification of the mecha, and the system administrator is the person with the highest management authority among all users of the mecha. The priority is the highest, higher than all other users, equivalent to being able to control all other mechs. At the same time, this system administrator can use the function of adding, deleting, modifying and querying users for all mechas, which means When the mecha is activated when it is purchased, there is a user registration, but the registration of this user is not permanent. If the user has various illegal operations during the use of the mecha, it means that the mecha It is completely possible to use the authority of the system administrator to remove the user's authority to use the mecha buyer. In fact, it is equivalent to a kind of supervision of the mecha by Yunfan Technology Company, which can effectively prevent the mecha purchaser from using the mecha. To do something that does not comply with the rules, so that the user of the mecha will not use the mecha unscrupulously. Once the user has any illegal operations, the system administrator, Liu Yun, can completely delete the mecha binding. User information, when the time comes, the user will not be able to enter the operation interface of the mech.In addition to the system administrator, there are also maintenance users. You can tell by the name. The so-called maintenance users are users who maintain the mech. When the purchaser of the mecha encounters a malfunction of the mecha, he can find the maintenance personnel of the mecha. Maintenance, and the system authority of these maintenance personnel is to improve the code of the mecha. Of course, this kind of improvement is limited. It can only fix the small system file errors of the mech. The maintenance personnel cannot modify it, because Liu Yun will not open the underlying code authority of the mecha system to the maintenance personnel of the mecha. He can only allow the users of the mecha to have enough authority to deal with minor problems of the mecha. The major problems of those mechas can be reinstalled to make the mechas come back to life, but this does not mean that the maintenance personnel have higher system permissions than the mecha purchaser users, because the mecha maintenance personnel It seems to be higher than the user's system authority, but it is not.The system authority of the maintenance personnel is different from the authority of the user of the mecha, and the two will not overlap. How to put it, it is equivalent to the user of the mecha having various rights to use the mecha, but There is no authority to modify the codes of some mechas, but the maintenance personnel of the mechas have the maintenance authority of the mechas, but they can only repair the codes of the mechas. This does not mean that the maintenance personnel of the mechas can replace The user of the mecha controls the mecha. In fact, the maintenance work of the maintenance personnel must be completed with the help of the user of the mecha. It is equivalent to the fact that the maintenance personnel of the mecha can only repair the code problem of the system of the mecha, but There is no authority to operate the mecha, because the maintenance personnel of the mecha cannot enter the system of the mecha without the user's password input, and the maintenance personnel of the same mecha cannot change the user password of the mecha. If the maintenance personnel want to change the password of the mecha, they need to know the original password, that is, they need to verify the original password. Only when the original password is verified can they proceed to the next step of password modification.

Therefore, the authority of the maintenance personnel of the mecha is not higher than the system authority of the user of the mecha, but there will be overlaps between these two authorities, and these are two different authorities. Permission is a kind of authority to change the code of the mecha. Of course, in order to limit the system authority of the mecha maintenance personnel, Liu Yun only opened up a small part of the code maintenance to the mecha maintenance personnel, and this small code repair Because it is impossible to have an impact on the security of the mech's system, that is to say, Liu Yun only opened up the modification function of a small part of the system files of the mech, and Liu Yun did not maintain the files that maintain the stable operation of the system. The authority of the stable operation of the mecha is given to the maintenance personnel of the mecha. This is to prevent the maintenance personnel of the mecha from making mistakes during the maintenance process, which will lead to some failures during the use of the mecha. Therefore, the system of the mecha Liu Yun is very cautious in this aspect of the document. At the same time, in order to allow users to use the various functions of the mecha more safely, Liu Yun also deliberately made some restrictions on the maintenance personnel of the mecha, such as making the maintenance of the mecha The personnel can only modify the code with the cooperation of the user of the mech. This will ensure that the maintenance personnel of the mecha cannot modify the user's code arbitrarily. This will prevent some mecha maintenance personnel from deliberately giving the user's machine A accident can effectively prevent rat droppings among the maintenance personnel, and ensure the maintenance work of the maintenance personnel more safely.At the same time, in order to further standardize the maintenance work of the maintenance personnel, Liu Yun also stipulated that the whole process of mecha maintenance must be videotaped, and the recorded video will be sent back to Yunfan Technology Company through the network, as the user of the mecha. If you want to view the video of the mecha being repaired at that time, you can log in to the website of Yunfan Technology Company to watch the situation of the maintenance personnel repairing the mecha at that time.Of course, not everyone can view the maintenance videos of the mecha at will. Only the owner of the mecha can view the maintenance videos of the mecha. As for other people, they cannot view the use videos of the mecha. At this time, Yunfan Technology Company will check the invoice to determine whether the user has the right to view the repair video at that time. After checking that the user can indeed view the video at this time, Yunfan Technology Company will check the video of the mecha repair at that time. Issued to the user of the mecha, at this time the user of the mecha can carefully watch the specific maintenance process of the mecha. If the maintenance worker of the mecha has any bad behavior during the maintenance process, the mecha Users can completely complain to the maintenance personnel of the mecha based on the content in the video of the mecha. Once Yunfan Technology Company confirms that the maintenance workers of the mecha did have illegal operations during the maintenance process, Yunfan at this time The technology company will punish the mecha maintenance workers according to their behavior. If the circumstances are relatively minor, they will be punished slightly, but if the circumstances are more serious, the mecha maintenance workers will be fired in a breach of contract.
