When the annual college entrance examination on the security industry to add new power

Today is June 7, the national college entrance examination opened. According to statistics, the total number of enrollment applications for colleges and universities in the country in 2011 was approximately 9.33 million. Among them, the number of students enrolled in regular high school graduates is basically the same as last year, and the enrollment of new students has decreased by 280,000 over the previous year, a decrease of 15%. As the total number of college entrance examination applications has decreased, the number of applicants for college entrance examinations in 12 provinces and autonomous regions has increased compared to last year, and most of them are located in the western region. The average national admission rate this year is expected to increase by nearly 4 percentage points from last year to 72.3%. The nation’s million students rushed to the battlefield, and thousands of troops passed the single-plank bridge. The competition was “terrorous”. However, with the development of science and technology, various zuobi methods are also varied. In order to prevent the occurrence of the zuobi incident, campuses throughout the country are preparing for security monitoring every year. The 2011 college entrance examination opened, what new security members to help?

Metal Detector: When irrelevant items are all taken out of the test room, they will be inspected by the invigilator. Except for 2B pencils, pens (pen, ballpoint pen), rubber and other test items that can be carried, candidates must not carry any communication tools (eg mobile phones, radio receivers, transmission equipment), electronic storage memory devices, and alterations that are not related to the examination. Liquids, metal products, etc. enter the examination room, and timing instruments including watches are not allowed to enter the examination room.

Do not question whether it really can play a role, first look at the characteristics of hand-held metal detectors: hand-held metal detector easy to use, detect metal objects respond quickly, when the metal is detected, both sides of the Alert light can issue a red alarm Simultaneous alarm sound and LED illumination; high accuracy and sensitivity for accurate detection of very small metal objects (0.1g or even smaller); clear low-frequency tone emitted when detecting smaller metals Acoustic, which emits high pitch tones when detecting large metal objects.

Network Video Surveillance System: The examination hall records every move to improve the management efficiency of the national educational examinations and provide sufficient technical guarantees for the safe operation of the national educational examinations. The Examination Center of the Ministry of Education proposes to establish a “National Education Exam Online Inspection System” and establish a nationwide coverage system. The video surveillance network at all levels of test institutions and test centers enables the monitoring and commanding of the examination process and the confidential room.

Radio signal shielding wall: zuobi good control measures In order to maintain the interests of the vast majority of candidates, the zoubi behavior of a few people must take the necessary control measures, the examination management department also adopted a radio shielding this approach.

During the radio signal monitoring vehicle examination, the surrounding environment of the examination room and the examination room shall be closely monitored in all directions. All monitoring stations and monitoring vehicles will enter the status at the appointed time. All radio frequency bands will be comprehensively monitored. Once abnormal signals are found, they will be taken immediately. Signal interference measures block the signal.

Some parents of the candidates felt uneasy about this, and they feared that it would affect the normal performance of the children's college entrance examination. In fact, these devices will not harm the examinees and the examination staff's body, and will not affect the candidates' normal answers. Because the radio signal shielding equipment used in the examination room is a micro-power equipment, its transmission power is generally less than 3W, and it is also used in corridors outside the examination room. In this case, the body's specific absorption of electromagnetic waves is minimal. Therefore, the radio signal shielding equipment used in the examination room does not pose a hazard to human health.

Handheld Wireless Stealth Headphone Detector: Let Invisible No longer "Invisible"

With the development of technology, more and more high-end zuobi products are exposed in the market. Wireless stealth headset is a special technology product, formerly known as "miniature voice prompter", which is mainly used for broadcasting stations and other purposes. Since the invisible headphone receiver is only soy-sized and can be put into the ear canal, it is difficult to find such a product if it is used for examination cheating. Hand-held wireless stealth headset detectors can make stealth no longer "invisible."

Concluding remarks Students are already in the midst of intense work. A new batch of talented people will add luster to the community. Security products metal detectors, network video surveillance systems, radio signal shielding walls, radio signal monitoring vehicles, handheld wireless stealth headset detectors will escort for the 2011 college entrance examination, so that the annual college entrance examination draws a more satisfactory conclusion.
