The most rigorous college entrance examination in history: drones are used to monitor candidates

[China Agricultural Machinery Industry News] UAVs have long been used in the military field. In recent years, with the development of drones, more and more "flying into the homes of ordinary people" has not only played a huge role in agriculture, but also completed some people who could not complete the human race in daily life. The drone is used in the college entrance examination, have you heard it?
Strict examination in history: UAVs are used to monitor candidates
Candidates are not allowed to bring any items (including stationery) other than the ID card and the admission ticket into the examination room. At the same time, the monitoring probe is set up in the examination room, and the invigilation is also increased to 3 people, which is called strict history. Luoyang City, Henan Province also invited the drone to monitor the radio electromagnetic environment around the test center.
The annual college entrance examination (excellent class) is about to arrive. It seems that the calm and quiet examination room has hidden contests of cheating and anti-cheating. In Henan Province, where there are many candidates, there are a number of test disciplines issued this year. This includes not allowing candidates to bring any items (including stationery) other than ID documents and admission tickets into the examination room. At the same time, monitoring probes are set up in the examination room. The increase to 3 people is a strict history. Although the in-house proctoring has been so strict, Luoyang City feels that it is still not enough. It decided to use some high-tech cheating methods to make a heavy punch. The drone was invited to monitor the radio electromagnetic environment around the test center.
It is understood that this six-rotor UAV can "capture" radio signals at full frequency and implement tracking and positioning. It can fly close to a kilometer, can hover for a long time at 500 meters high 'ideal working height' and perform 360-degree rotation and scanning. The endurance of air can last for half an hour, and it can resist the strong wind of 4-5.
The drone's operating software interface has a "corrugated display" similar to the "electrocardiogram" trend and a map near the test site. Once a suspicious signal appears nearby, the “ECG” will generate corresponding fluctuations, and by positioning, the system can quickly and accurately provide the reference position where the source is located.
