Description

Authentication device of high-low temperature box

Technical Field

The utility model relates to the field of automatic testing, in particular to an authentication device of a high-low temperature box.

Background

Radio Frequency Identification (RFID) is an abbreviation of Radio Frequency Identification, and the principle is that a reader and a tag perform non-contact data communication so as to achieve the aim of identifying a target. The RFID is widely applied, and is typically applied to animal wafers, automobile wafer burglar alarms, access control, parking lot control, production line automation and material management.

Technical problems: environmental testing is a long and rigorous test that all electronic products must go through in the research and development stage, just because it is long time, some time is 7×24 hours, even if there is monitoring in the laboratory, once because the test is unusual because of artificial factor, it is difficult to find out by monitoring who is the problem again, even if found out again.

In the long-time process of environmental test, because personnel in the environment are complex, it is difficult to know who moves the setting of the incubator to the end, so that the test is abnormal; ensuring that unauthorized persons cannot move the configuration of the incubator during the test process, and further reducing test failures caused by human factors is an original design of people.

The beneficial effects are that:

Compared with the traditional monitoring means and configuration modes, the utility model has the advantages that an authentication means is added when a user uses the touch screen to configure the incubator, and false touch can be effectively avoided; in addition, even if someone illegally obtains permission, the setting of the incubator is changed to cause test failure, corresponding personnel can be found by searching a record on the server, the efficiency of environment investigation is greatly improved, and the following aspects are particularly shown:

effectively avoiding false touch: conventional environmental monitoring approaches may not prevent the environment from being touched by mistake, which may lead to anomalies in the testing process. However, the utility model introduces an authentication means when the user touch screen configures the incubator, so that only a legally authorized user can be ensured to configure. The feature effectively avoids false touch and improves the reliability of the test.

Monitoring and tracking of illegal rights: traditional methods may not be effective in monitoring and tracking illegally authorized personnel and the test may fail once the incubator settings are altered. However, the present utility model enables detailed recording of each card swipe event, including user identity and changes made, through an authentication server connected to the internal network. This makes it easy to track illegally authorized persons and to find the corresponding person quickly. This improves the efficiency of the environmental investigation and reduces the risk of failure of the test due to illegal intervention.

Convenience of configuration is improved: the utility model also improves the convenience of configuring the incubator. The user can configure through the touch screen without cumbersome extra steps such as using physical buttons or external devices. Therefore, the configuration flow can be greatly simplified, and the user experience is improved.

Enhancing the safety of environmental monitoring: through the combination of the main control chip module and the internal network, the utility model enhances the safety of environmental monitoring, and only authorized users can access the configuration of the incubator, thereby ensuring the stability and reliability of environmental parameters.
