The base station system receives the early warning information from the control center platform and synchronously blocks 4G/5G (SIM, IoT) card signals.
The existing 'base station system' has powerful functions and mature and reliable technology, completely meets the technical requirements of accurate calculation, accurate identification and fine control, completely meets the condition of blocking 4G or 5G communication link signals because the switching speed between the base stations is millisecond-level, has the capability of closing a single base station or a plurality of base stations, is competent for independently closing any 4G/5G (SIM, IoT) card near the base station, and can timely intervene and report the information of a card holder for an 'abnormal' aircraft or a ground moving target and a water surface moving target. According to the size of the defense area, the macro base station and the micro base station of the 'base station system' participating in blocking the 'abnormal' unmanned aerial vehicle can be increased, decreased or cancelled at will so as to meet the requirements of different defense targets.
Early warning equipment units (radar, frequency spectrum, photoelectricity) in the 'control center platform' can all weather, search for 'unusual' unmanned aerial vehicle in the important defense range all the day, once find 'unusual' unmanned aerial vehicle, immediately take the tracking, fix a position, discernment, report radar, frequency spectrum, photoelectricity information to the control center platform simultaneously, record the basic station information and the orbit information that this unmanned aerial vehicle passed through simultaneously, compare with the geographical map information of 'control center platform', intelligence is compared the information base, the very first time is fed back to 'control center platform', intelligent control center platform assigns the disposition order. The blocking function of the base station system is started to cut off the communication signal of the abnormal unmanned aerial vehicle 4G/5G (SIM, IoT) card, all anti-unmanned aerial vehicle equipment under the control center platform is started, and multi-level, multi-hand and multi-industry cooperative treatment is carried out on the unmanned aerial vehicle losing 4G/5G.
The early warning equipment unit under the control center platform comprises a low-small slow phase control array radar, an infrared night vision photoelectric unit and a passive frequency spectrum detection unit. The low-small slow-phase control array radar carries out radar detection, the radar detection technology is widely adopted, and the early warning equipment for defending a target is formed by acquiring the position of the target accurately due to mature technology and long detection distance.

The navigation is tricked into through forging protocol code (mainly being GPS code) of unmanned aerial vehicle and remote controller, launches false navigation signal to take over or tricked into unmanned aerial vehicle, return voyage or landing in certain extent, and the shortcoming of this technique is that there is certain influence to other products that use navigation equipment, has great interference to communication base station's time service system. In addition, the anti-unmanned aerial vehicle equipment can also adopt a protocol cracking technology, and the unauthorized 'black flying' unmanned aerial vehicle is driven away by cracking a bottom layer protocol in the unmanned aerial vehicle control system and utilizing technologies such as intelligent frequency modulation, software codes and narrow band suppression. The unmanned aerial vehicle is subjected to physical striking by using equipment such as high-power laser, high-power electromagnetic pulse and conventional weapons, so that the real effect is good.
The working principle of the detection and defense method of the 4G or 5G unmanned aerial vehicle is as follows: firstly, in a low-altitude security defense system of some important targets, phased array radars or frequency spectrum detection equipment are arranged and used for assisting omnidirectional scanning to search for unmanned aerial vehicles; the existing unmanned aerial vehicle security defense management and control platform is used for overlapping modeling of a geographic map in an important target and a geographic map of a base station system, and intelligent supervision is implemented on a moving target around the range of the important target; 4G/5G communication base stations (macro or micro) participating in blocking unmanned aerial vehicles around the range of the important target are basically in a star-shaped layout with the length of 300-500 meters, as shown in FIG. 3, the switching response time is in millisecond level, and the switching-off can be carried out on any 4G/5G (SIM, IoT) card; when the base station system monitors that the moving speed of a moving object is greater than a preset speed and the moving object crosses a fixed entity (a non-aerial vehicle cannot do so) based on a 4G or 5G communication signal, the moving object is assumed to be a suspected unmanned aerial vehicle target, meanwhile, when a phased array radar or spectrum detection device assists in searching and detecting an invading unmanned aerial vehicle, information such as geographic coordinates, longitude, latitude, altitude and the like of the unmanned aerial vehicle is reported to a control center platform, and the control center platform notifies that a moving 4G/5G (SIM, IoT) card is closed; the closed unmanned aerial vehicle carrying the 4G/5G (SIM, IoT) card lacks the technical support of the communication data of 4G/5G, the anti-interference capability is greatly reduced, and the remote 'destruction' capability is lost.
The base station system is only managed by a control center platform in the whole process, has the main functions of blocking 4G/5G (SIM, IoT) cards and reporting cardholder information at the same time, does not need to conduct behavior judgment on the target unmanned aerial vehicle, and does not participate in the treatment of driving away and forcing to land on the target unmanned aerial vehicle. In the low-altitude security defense system of the important target, the anti-braking equipment (anti-unmanned aerial vehicle equipment) is utilized to strike the invading unmanned aerial vehicle in a full force manner, so that the safety of the important target is ensured.
In the method, the step D may further include determining whether the height of the suspected drone target exceeds a predetermined height, and the step F is: when the suspected unmanned aerial vehicle target is determined to be higher than a preset height, span an entity on an entity map and be judged to be an unmanned aerial vehicle by combining an auxiliary detection device, the control center platform sends early warning information to the base station system, and the base station system blocks a 4G or 5G communication link signal of the unmanned aerial vehicle.
The invention provides a brand new decision rule for detecting and blocking a 4G or 5G unmanned aerial vehicle, which comprises the following steps: firstly, a telecommunication signal emission source moving at a high speed or moving irregularly is found by using a first network woven by a telecommunication base station and a network, and the emission source is preliminarily assumed to be a suspected unmanned aerial vehicle target; analyzing the base station interconnection condition generated by the displacement of the suspected unmanned aerial vehicle target between the gridding base stations, drawing a base station interconnection path, comparing the base station interconnection path with geographic information map data, and judging whether the suspected unmanned aerial vehicle target irregularly spans buildings, roads, rivers, bridges and the like because the non-aerial vehicle cannot realize the irregular displacement; and finally, auxiliary detection of a radar, a frequency spectrum and a photoelectric device is added, the characteristics of the suspected unmanned aerial vehicle target are comprehensively calculated, whether the suspected unmanned aerial vehicle target is an unmanned aerial vehicle or not is judged by a software algorithm arranged on a control center platform, and a command is issued to perform the next action to block the unmanned aerial vehicle.
According to a preferred embodiment of the present invention, the detection and defense method further comprises: uploading information of the unmanned aerial vehicle flight activities which meet road traffic regulations, sailing ship laws and/or government approval to a control center platform; and said step F further comprises: when the flight time and the route of the unmanned aerial vehicle are matched with the information, the control center platform does not send early warning information to the base station system and does not block the unmanned aerial vehicle.

Advantageously, in step F, when the control center platform sends the warning information to the base station system, all the anti-drone devices under the control center platform are turned on, and the drone that loses the 4G or 5G communication link signal is countered. Advantageously, the detection and defense method further comprises: and dividing the actual geographic landform in the monitoring range into grids with the same area, and establishing a monitoring station in each grid to form multi-station networking operation.
