1 Analysis of UAV shielding system deployment requirements.
In recent years, UAV technology has spread rapidly and extensively, and a large number of remote-controlled multi-rotor aircraft have emerged that are easy to control, with multi-rotor aircraft as the main form of low-altitude and slow-speed small target UAVs (hereinafter referred to as UAVs) have developed rapidly, and their aerial camera, volley arrival, real-time image transmission, transportation and other capabilities have brought new challenges to confidentiality, security and anti-terrorism work. In the future, anti-drone technology will certainly play an important role in the field of security. In addition, anti-drone systems are emerging equipment, which can help promote the development of technologies in the fields of microsystems, electromagnetic spectrum, and directed energy.
Explain the deployment requirements of our company's self-developed UAV shielding system.
1.1 Potential risk assessment.
Whether it is a civil aircraft or a military aircraft, the take-off and landing process of its airport needs a certain range of "clear space" to protect, so as to ensure the safety of flight. However, in recent years, a large number of unmanned aerial vehicles (UAVs) can intrude into the "clear space" management area of the airport at any time without constraints, causing aviation unsafe incidents and bringing huge losses to the aviation industry.
1.2. Divulging privacy and state secrets.
The cameras, audio recordings, and some special secret-stealing equipment provided by drones will seriously infringe on the privacy of private homes and the information security of sensitive areas such as national and military bases. Unmanned aerial vehicles (UAVs) invade airports and important places to track and photograph the whereabouts of residents, seriously hindering personal privacy and may also cause the leakage of trade secretsDrones can infiltrate military facilities, be able to track and photograph the movement of military equipment, map core areas such as military bases and airports, etc., all of which can cause military secrets to be leaked.
Real-life examples include:
On the afternoon of November 17, 2015, during the training flight of a certain unit of the Air Force in Zhuozhou, Hebei Province, 15 kilometers west of the airport, a low-flying drone was found. At the same time, a ground team was dispatched to assist the local public security forces to rush to the forced landing area in time to control the personnel involved and the drones. After a preliminary investigation, the drone was owned by an aviation technology company in Beijing, and the flight plan was not declared on that day. In addition, multiple drones of this company were found.
According to the statistics of the 2017 Spring Festival Gala Security Headquarters, as of January 25, 2017, 24 drones have been driven away from the core area, and 6 drones have been shot down and confiscated, avoiding the leakage of the Spring Festival Gala program and site security.
The main product forms.
The system mainly includes two product forms: stationary and vehicle-mounted.
The fixed defense system is mainly deployed in a relatively fixed security perimeter, and the perimeter is safeguarded, and the product is connected to the system by wire, and the radio interference shielding system installed on the roof of the building constitutes a complete defense system.
Shielding capabilities. Shielding capability refers to the ability to take shielding measures to effectively shield invading drones. A single device has a shielding distance of 1km for a typical commercial drone.
3.1 Fixed deployment scheme.
The fixed deployment scheme is a long-term deployment scheme, which is suitable for the use of Longguang Jiuzhuan under the condition that it remains basically unchanged for a long time. Prevent drones from flying into Longguang's airspace, aerial photography or dropping bombs, bringing unnecessary economic losses to Longguang Therefore, unattended shielding stations are installed and fixed deployment schemes. Fixed deployment scheme for directional interference shielding.
As an excellent security equipment manufacturer, Texin independently develops UAV shielding equipment, which can interfere with GPS satellite positioning signals; At the same time, it can be commonly used for UAVs ISM 24G and ISM 5The 8G frequency band is jamming and shielding, forcing the UAV to remote control, image transmission and positioning, and signal interruption, so as to achieve the effect of forced landing, return to home, and hovering. Texin Communication independently developed UAV shielding equipment, which has strong functions and a long interference distance, which can reach 1-3 kilometers.
Shielding range: 1000 meters 2000 meters (2.)4g 100w 1.5g 50w 5.8g 20w）
Fine technical parameters
Product features
1. Cut off all communication between the drone and the controller: the drone control fails.
2. The ground control of the UAV cannot receive aerial photography
3. The drone cannot be positioned; The interceptor can force the drone to land or return.
Precautions
The effective shielding range of UAV shielding equipment will be different in different use sites. This is closely related to the signal field strength in the field. Different types of UAVs do not necessarily have the same shielding range at the same site;
Factors affecting the shielding range include but are not limited to: distance, power, orientation, obstacle obstruction relative to the drone, the material of the wall of the on-site building, the installation height of the shield, installation specifications, etc.;
Each antenna has a frequency band identification, which must correspond to the frequency band on the host, and the antenna connection must be reliable before the shielding device is turned on. It is never allowed to be turned on without connecting the antenna;
It can be wall-mounted or mounted on a pole with a hoop; The installation height is recommended 3 15 meters;
When installed outdoors, the host and antenna should be under the lightning rod;
This UAV shielding equipment is a high-power model, high-power shielding for the building shielding coverage, the shielder can not be installed in the building (the steel-concrete structure of the wall will attenuate the transmission of the signal greatly), but should be installed in the front and rear of the target area 20 30 meters position, at the same time the installation height should also be appropriate, there is no obstacle between the antenna and the target building;
