The high school entrance examination is the only way for every student to go to school, and it is also an examination that affects the fate of hundreds of millions of people in my country's selection of talents. It is not only students, teachers and parents who face the test of the high school entrance examination, but also a test for education departments and government units at all levels. Every year during the middle and high school entrance examinations, we will see news, such as which test centers have not been properly guaranteed, which test centers have not set up emergency measures, which invigilators have made mistakes, and so on. Among them, the most serious one was last year when Wu Moumou, a candidate from Wuhan, illegally brought a mobile phone into the examination room to shoot the test paper and then uploaded it to the Internet. Of course, the invigilators were negligent in the entry security check and invigilation. The Huangpi District Admissions Office said in response to this matter, or because of A loophole in the 5G signal shielding caused the candidate to upload the test questions on his mobile phone.

On the one hand, it is the importance of the high school entrance examination, and on the other hand, there are some loopholes in the signal shielding of the high school entrance examination. Therefore, the optimization and improvement of the signal blocker for the high school entrance examination in 2022 is imminent! So what changes have been made to the signal jammer for the high school entrance examination in 2022?

1. [The developer said] The increase in the change of the signal shielding device for the high school entrance examination in 2022 is inevitable:

5G commercial licenses have been issued in 2019. After several years of base station construction, the vast majority of first- and second-tier cities in my country have achieved effective 5G signal coverage. Therefore, the signal shielding device for the high school entrance examination must increase the shielding of the 5G frequency band. In particular, the occurrence of the question leak incident in Wuhan last year has also strengthened the determination of the examination departments in various regions to optimize the signal jammers in the original examination room and increase the signal frequency band that can be shielded. At present, the signal blocker specially developed and produced by Ningbo Dazhan Electronic Technology Co., Ltd. for the high school entrance examination can effectively block all cheating signals such as 2345G mobile phone signals, WiFi Bluetooth signals, etc. It is the leader in the industry.

2. [The developer said] The intelligent networking control of the change of the signal jammer for the high school entrance examination in 2022 is the trend:

With the development of society and the advancement of technology, the requirements for jammers have also increased. Ningbo Dazhan Electronic Technology Co., Ltd. has also taken the lead in producing intelligent networked signal jammers. Compared with ordinary signal jammers, , What are the advantages of intelligent networked control signal jammer?

1. Turn on and off the smart shield with one key of the remote host;

2. Nine working periods, the working hours of each working period can be freely set by the user according to the actual use requirements;

3. Report the working status to the intelligent shielding management system in real time, and users can monitor the working conditions of each intelligent shielding device;

4. The fault will be automatically alarmed and the power supply of the main board of the intelligent shielding device will be cut off. It is not only safer, but also effectively prolongs the life cycle of the smart shield;

5. In the list state of the intelligent shielding management system, the working voltage and current of all the intelligent shielding devices in the online and standby states are displayed in real time;

6. The follow-up maintenance and repair are very convenient, and the working status of the equipment can be judged only by the icon color of the intelligent shielding device in the intelligent shielding management system. Green is online, red is standby, yellow is alarm, and gray is offline.

3. [The developer said] The normalized use of signal jammers for the college entrance examination in 2022 is development:

How to define the normal use of signal jammers? The editor of Dazhan Electronics believes that it is normal for all classrooms as examination rooms to use signal jammers when they are not taking exams. In fact, signal jammers are not only used for cheating in exam rooms. In order to prevent students from indulging in mobile phones, many schools have installed signal jammers in classrooms and dormitory areas to shield signals.

The normal use of signal jammers has correspondingly increased requirements for equipment, requiring better power supplies, better cooling systems, and better electrical components, which is also a test for signal jammer manufacturers. The test room signal jammers produced by Dazhan Electronics can meet the needs of uninterrupted power supply throughout the year!

And all of this is also for the high school entrance examination, so that students can focus on their studies and give full play to their talents in these two important exams!
