一种增强型机场场面监视系统An Enhanced Airport Surveillance System

技术领域technical field

本发明涉及一种增强型机场场面监视系统，特别是一种利用分布安装的多台主动式探测设备增强场面监视性能的监视系统。The invention relates to an enhanced airport surface monitoring system, in particular to a monitoring system which utilizes a plurality of active detection equipment installed in a distributed manner to enhance the surface monitoring performance.

背景技术Background technique

自从机场产生以来，机场场面监视技术就是采取塔台管制员人工监视管理机场的方式，随着航空运输业的飞速发展，此种方式已经不能满足机场地面交通安全的需要，因此逐步产生了不同的机场场面监视系统，其中最早出现的是基于场面监视雷达的系统。Since the emergence of the airport, the airport scene monitoring technology has adopted the method of manually monitoring and managing the airport by tower controllers. With the rapid development of the air transport industry, this method can no longer meet the needs of airport ground traffic safety, so different airports have gradually emerged. The surface surveillance system, the earliest of which is based on the surface surveillance radar system.

机场场面监视雷达是上世纪70年代以后逐步投入使用的一种专门用于监视机场地面飞机与车辆活动的雷达，由旋转天线、发射机、接收机、信号处理器、数据处理器和显示系统组成，场面监视雷达为了保证环境安全，对辐射功率有严格限制，因此影响对于地面车辆和人员的探测能力，漏警率和虚警率高，并且刷新率受到天线转速限制无法提高，最重要的是场面监视雷达价格非常昂贵，通常特大型机场也仅安装一部雷达，导致探测覆盖范围受限，存在大量盲区。The airport scene surveillance radar is a radar specially used to monitor the activities of aircraft and vehicles on the airport ground, which has been gradually put into use since the 1970s. It consists of a rotating antenna, a transmitter, a receiver, a signal processor, a data processor and a display system. , In order to ensure the safety of the environment, the surface surveillance radar has strict restrictions on the radiation power, so it affects the detection ability of ground vehicles and personnel, the false alarm rate and false alarm rate are high, and the refresh rate cannot be increased due to the limitation of the antenna speed. The most important thing is Surface surveillance radars are very expensive, and usually only one radar is installed in very large airports, resulting in limited detection coverage and a large number of blind spots.

为了克服场面监视雷达的缺点，以较低的成本建立起场面监视系统，国际上开发了一些不依赖于场面监视雷达的被动式场面监视系统，主要包括基于ADS-B的机场场面监视系统和基于多点定位方式的机场场面监视系统。In order to overcome the shortcomings of the surface surveillance radar and establish a surface surveillance system at a lower cost, some passive surface surveillance systems that do not rely on the surface surveillance radar have been developed internationally, mainly including the airport surface surveillance system based on ADS-B and the An airport surface surveillance system in point positioning mode.

ADS-B(Automatic Dependent Surveillance-Broadcast，即广播式自动相关监视)，是新航行系统的重要组成部分。ADS-B的工作原理是在每架飞机或车辆上装有全双工无线通信装置支持高速数据通信，由它定时广播本身的一些信息，这些信息包括速度矢量、位置、识别码等数据。这样管制员和每架飞机或车辆都能收到在附近所有的广播信息，得到它们的速度矢量、位置、识别码等信息，通过对这些数据的处理可以了解一定范围内的交通态势。这样的优点是机场管制塔台接收所有飞机、车辆的广播报文，得到它们的实时运动趋势，机场管制员能够清楚直观地了解机场的交通状况，实现高质量的场面监视；但是缺点在于：需要特定的机载设备，飞机需要实施改装；无法监控未安装此类设备或设备突发故障的车辆及人员。ADS-B (Automatic Dependent Surveillance-Broadcast, Automatic Dependent Surveillance-Broadcast) is an important part of the new navigation system. The working principle of ADS-B is that each aircraft or vehicle is equipped with a full-duplex wireless communication device to support high-speed data communication, and it regularly broadcasts some information of itself, including speed vector, position, identification code and other data. In this way, the controller and each aircraft or vehicle can receive all the broadcast information in the vicinity, and obtain information such as their velocity vector, position, identification code, etc., and can understand the traffic situation within a certain range by processing these data. The advantage of this is that the airport control tower receives the broadcast messages of all aircraft and vehicles and obtains their real-time movement trends. The airport controller can clearly and intuitively understand the traffic conditions of the airport and realize high-quality scene monitoring; but the disadvantage is that it requires specific The aircraft needs to be modified; it is impossible to monitor vehicles and personnel that are not equipped with such equipment or fail suddenly.

多点定位技术(Multilateration)是国外提出的一种机场场面新型监视技术，该技术充分利用民航飞机标准应答信号或者VHF通信信号，采用多点无源传感器接收方式确定飞机或其他运动目标的位置。由于该系统可以完全兼容SSR雷达和ADS-B下行数据传输链路，可以接收和解码飞机SSR代码和S模式地址，因而具备目标标识能力和高精度定位能力。该技术的优点是充分利用机载现有标准应答机，而无需加装其他机载导航设备完成定位监视；兼容ADS-B技术；系统成本低，定位精度高，对其他系统干扰小。但是缺点在于无法监控未安装此类设备或设备突发故障的车辆及人员。Multilateration is a new type of airport surveillance technology proposed abroad. This technology makes full use of the standard response signal or VHF communication signal of civil aviation aircraft, and uses multi-point passive sensor reception to determine the position of the aircraft or other moving targets. Since the system is fully compatible with SSR radar and ADS-B downlink data transmission links, it can receive and decode aircraft SSR codes and S-mode addresses, so it has target identification capabilities and high-precision positioning capabilities. The advantage of this technology is that it makes full use of the existing airborne standard transponder without installing other airborne navigation equipment to complete positioning monitoring; it is compatible with ADS-B technology; the system cost is low, the positioning accuracy is high, and there is little interference to other systems. But the disadvantage is that it is impossible to monitor vehicles and personnel that are not installed with such equipment or fail suddenly.

综上所述，现有被动式机场场面监视系统可以以较低的价格满足机场地面运行的基本需要，但是也具有一些难以克服的缺点，包括：To sum up, the existing passive airport surface surveillance system can meet the basic needs of airport ground operations at a relatively low price, but it also has some insurmountable shortcomings, including:

1.完全依赖于机载/车载设备，对于未安装此类设备的车辆和个人，或安装的设备临时故障的车辆没有任何的预警能力；1. Completely rely on airborne/on-board equipment, and have no early warning capabilities for vehicles and individuals that are not equipped with such equipment, or vehicles with temporary failures of installed equipment;

2.数据刷新率和准确性难以进一步提高，需要保持较大的安全余量，影响了跑道和滑行道的运行效率。2. It is difficult to further improve the data refresh rate and accuracy, and it is necessary to maintain a large safety margin, which affects the operating efficiency of runways and taxiways.

有鉴于以上分析，本发明人针对现有的被动式机场场面监视系统进行研究改进，本案由此产生。In view of the above analysis, the inventor conducted research and improvement on the existing passive airport scene monitoring system, and this case arose from it.

具体实施方式Detailed ways

以下将结合附图，对本发明的组成结构和工作原理进行详细说明。The composition structure and working principle of the present invention will be described in detail below with reference to the accompanying drawings.

如图1所示，本发明提供一种增强型机场场面监控系统，包括被动式场面监视模块、空域主动探测模块、地面主动探测模块、监控模块和引导模块，下面分别介绍。As shown in Figure 1, the present invention provides an enhanced airport surface monitoring system, including a passive surface monitoring module, an airspace active detection module, a ground active detection module, a monitoring module and a guidance module, which will be introduced separately below.

被动式场面监视模块采用基于ADS-B技术或基于多点定位方式的机场场面监视设备101，用以确定所有安装所需机载/车载设备的飞机、车辆的位置。The passive scene monitoring module adopts the airportscene monitoring equipment 101 based on ADS-B technology or multilateration method to determine the positions of all aircraft and vehicles equipped with required airborne/vehicle equipment.

空域主动探测模块用于探测空中飞机的位置信息，实现对即将进入场面运行的降落飞机的预警。由于即将降落飞机的飞行高度很低，因此可以采用下述方法建立对即将进入场面运行的飞机的预警：The airspace active detection module is used to detect the position information of the aircraft in the air, so as to realize the early warning of the landing aircraft that is about to enter the scene. Since the flight altitude of the aircraft about to land is very low, the following methods can be used to establish early warning of aircraft about to enter the surface operation:

利用民航飞机受到飞行性能的限制，在降落中的最后进近航段必须保持直线飞行，即在跑道的延长线上飞行的原理，将毫米波测速雷达102作为探测器，安装于降落最后阶段航路的地面投影上，探测方向垂直向上，从而实现探测飞越该探测器上空飞机的功能。Utilizing the limitation of flight performance of civil aviation aircraft, the final approach segment during landing must maintain straight flight, that is, the principle of flying on the extension line of the runway, and the millimeter-wavespeed measuring radar 102 is used as a detector, which is installed on the flight path of the final stage of landing On the ground projection of the detector, the detection direction is vertically upward, so as to realize the function of detecting aircraft flying over the detector.

因为现代民航飞机在即将落地时飞行高度低，严格对准跑道，且此阶段飞行速度约为150～300千米/小时，所以使用毫米波测速雷达可以精确发现飞越的飞机，并利用速度取值范围消除飞鸟等虚警信号，实现主动探测。预警时间受毫米波测速雷达的探测距离的限制，设毫米波测速雷达最大探测距离h，飞机最后进近航段的下滑角θ，飞行速度v，则预警时间t为：Because the flight altitude of modern civil aviation aircraft is low when it is about to land, it is strictly aligned with the runway, and the flight speed at this stage is about 150-300 km/h, so the millimeter-wave speed measuring radar can accurately detect the flying aircraft, and use the speed value The scope eliminates false alarm signals such as flying birds and realizes active detection. The early warning time is limited by the detection range of the millimeter-wave speed measuring radar. Assuming the maximum detection distance h of the millimeter-wave speed measuring radar, the glide angle θ of the final approach segment of the aircraft, and the flight speed v, the early warning time t is:

$\mathrm{<span><span>t</span>t</span>}<span><span>=</span>=</span>\frac{\mathrm{<span><span>h</span>h</span>}}{\mathrm{<span><span>v</span>v</span>}<span><span>\&CenterDot;</span>\&Center\; Dot;</span>\mathrm{<span><span>tg\&theta;</span>tg\&theta;</span>}}<span><span>;</span>;</span>$

主动探测的结果传输到监控模块并融合被动式场面监视模块的数据，共同提供即将降落飞机的预警信息。The results of active detection are transmitted to the monitoring module and fused with the data of the passive surface monitoring module to jointly provide early warning information of the aircraft that is about to land.

地面主动探测模块安装在跑道和滑行道的交汇点等事故易发位置，采用的类型可包括毫米波雷达103、激光传感器104、红外传感器105和视频摄像机106，通过多种设备的复合安装以消除虚信号，避免因为机载/车载被动式定位设备故障而可能导致的不安全事件。The ground active detection module is installed at accident-prone locations such as the intersection of runways and taxiways, and the types used may include millimeter-wave radar 103,laser sensor 104,infrared sensor 105 andvideo camera 106, through the composite installation of multiple devices to eliminate False signals to avoid unsafe events that may be caused by the failure of airborne/vehicle passive positioning equipment.

毫米波雷达103安装于滑行道侧方，以探测飞机是否进入交叉口并得到运动速度，目的是通过速度判定飞机处于起飞滑跑状态或正常地面滑行状态，对于地面滑行状态则进一步判断预计通过下一个探测点的时间。The millimeter-wave radar 103 is installed on the side of the taxiway to detect whether the aircraft enters the intersection and obtain the speed of movement. The purpose is to determine whether the aircraft is in the state of take-off and taxiing or normal ground taxiing state through the speed. The time of a probe point.

激光传感器104安装于跑道侧方，平行于跑道方向，可以使用较少的探测装置确定多个交叉道口是否有飞机或车辆通过。激光传感器可以每隔800米安装一台，因为按照中国民航的规定，当机场的地面能见度低于800米时通常应当终止运行。Thelaser sensor 104 is installed on the side of the runway, parallel to the direction of the runway, and can use fewer detection devices to determine whether there are planes or vehicles passing through multiple crossings. Laser sensors can be installed every 800 meters, because according to the regulations of China's civil aviation, when the ground visibility of the airport is lower than 800 meters, the operation should usually be terminated.

红外传感器105的探测方向采用朝向斜上方，利用飞机的垂直尾翼高度超过普通车辆的原理，可以判断通过此道口的运动物体是飞机、车辆或行人。如图2所示，当飞机203通过时，高大的垂直尾翼可以同时触发对置于滑行道两侧的红外传感器201和202；如果是车辆204通过时，则只会触发一部传感器；如果有运动物体触发激光传感器而红外传感器没有显示时，则是行人，并应当实施进一步确认。The detection direction of theinfrared sensor 105 adopts towards obliquely upwards, and the principle that the height of the vertical tail of the aircraft is higher than that of ordinary vehicles can be used to determine whether the moving object passing through the crossing is an aircraft, a vehicle or a pedestrian. As shown in Figure 2, when theaircraft 203 passes, the tall vertical tail can simultaneously trigger theinfrared sensors 201 and 202 opposite to the taxiway both sides; if thevehicle 204 passes, then only one sensor will be triggered; When a moving object triggers the laser sensor but the infrared sensor does not display it, it is a pedestrian and further confirmation should be carried out.

视频摄像机106可以遥控转向可疑区域进一步确认是否存在不安全状况。Thevideo camera 106 can remotely turn to the suspicious area to further confirm whether there is an unsafe condition.

主动探测的结果传输到监控模块并融合被动式场面监视模块的数据，共同提供对机场场面运行环境的监控。The results of active detection are transmitted to the monitoring module and fused with the data of the passive surface monitoring module to jointly provide monitoring of the airport surface operating environment.

监控模块用于对前述各模块采集的信息进行综合处理，并判断是否实施告警动作，在本实施例中，监控模块采用了数据处理计算机107，被动式场面监视模块获得的信息，空域主动探测模块、地面主动探测模块获得关键位置的信息，共同传输给数据处理计算机107，采用数据融合技术建立有关机场场面的监视信息，当被动式监视设备(即被动式场面监视模块)和主动式监视设备(即空域主动探测模块和地面主动探测模块)的数据相互矛盾时自动实施告警。The monitoring module is used to comprehensively process the information collected by the aforementioned modules, and judge whether to implement an alarm action. In this embodiment, the monitoring module uses adata processing computer 107, the information obtained by the passive scene monitoring module, the active airspace detection module, The ground active detection module obtains information on key locations, and transmits them to thedata processing computer 107, and uses data fusion technology to establish surveillance information about the airport scene. When the data of the detection module and the ground active detection module) are inconsistent with each other, an alarm is automatically implemented.

针对监视信息，通过调用事先建立的探测结果和潜在不安全事件的逻辑关系库，当判断为可能的不安全事件时通过引导模块立即暂停飞机运行，并提醒工作人员采取进一步处置措施。For the monitoring information, by calling the pre-established detection results and the logical relationship library of potential unsafe events, when it is judged as a possible unsafe event, the aircraft operation will be suspended immediately through the guidance module, and the staff will be reminded to take further disposal measures.

在本实施例中，引导模块采用引导灯光设备108，其安装在事故易发位置，当没有风险时为绿色，飞机可以按照进入该区域；当监控模块判断可能在此位置存在不安全事件时为红色，提醒飞机立刻停止运行，避免进入该危险区域。如图3所示，探测器301发现有车辆307进入该区域，在其他探测器302至304没有发现其脱离该区域时，控制引导灯305显示红色，禁止飞机306通过黄色限制线，当确认风险已消除后，引导灯305变为绿色，以许可飞机通过此区域。In this embodiment, the guide module adopts guidelight equipment 108, which is installed in an accident-prone position. When there is no risk, it is green, and the aircraft can enter this area according to the rules; when the monitoring module judges that there may be an unsafe event at this position, it is Red, to remind the aircraft to stop immediately and avoid entering the dangerous area. As shown in Figure 3, thedetector 301 finds that avehicle 307 enters the area. Whenother detectors 302 to 304 do not find that it leaves the area, the control guide light 305 displays red, and theaircraft 306 is prohibited from passing through the yellow limit line. When the risk is confirmed Once cleared, theguidance light 305 turns green to clear the aircraft to pass through the area.

综上，本发明将现行被动式机场场面监视设备101，在跑道延长线上安装的毫米波测速雷达102、跑道和滑行道关键位置水平安装的毫米波雷达103、激光传感器104、红外传感器105和视频摄像机106，通过数据链网络同数据处理计算机107、引导灯光设备108等相连接，实现通过对关键区域附近飞机位置的主动探测，弥补现有系统完全依赖机载/车载设备的局限性，提高其数据刷新率和准确性，提高处置不安全事件的效率，增强现有基于被动式监视技术的场面监视系统的性能。In summary, the present invention combines the existing passive airportscene monitoring equipment 101, the millimeter-wavespeed measuring radar 102 installed on the runway extension line, the millimeter-wave radar 103 installed horizontally at key positions on the runway and taxiway, thelaser sensor 104, theinfrared sensor 105 and the video Thecamera 106 is connected with thedata processing computer 107 and the guidinglighting equipment 108 through the data link network, so as to realize the active detection of the position of the aircraft near the key area, make up for the limitation of the existing system completely relying on the airborne/vehicle equipment, and improve its performance. Data refresh rate and accuracy, improve the efficiency of dealing with unsafe incidents, and enhance the performance of the existing scene surveillance system based on passive surveillance technology.

当需要降落的飞机在最后进近航段的飞行中飞越毫米波测速雷达102时，数据处理计算机107将判定此时跑道处于被占用状态，所有进入跑道的滑行道口的引导灯光设备108将显示红色以禁止任何运动物体进入；如果有物体闯入则系统将向管制员告警，由其指挥空中飞机复飞。When the aircraft that needs to land flies over the millimeter-wavespeed measuring radar 102 during the flight of the final approach segment, thedata processing computer 107 will determine that the runway is in an occupied state at this time, and theguide lighting equipment 108 of all taxiway crossings entering the runway will display red. In order to prohibit any moving objects from entering; if an object breaks in, the system will give an alarm to the controller, who will direct the air plane to go around.

当降落的飞机开始脱离跑道时，安装于滑行道口的主动探测设备一经确认飞机已经脱离，数据处理计算机107将判定此时跑道处于空闲状态，所有进入跑道的滑行道口的引导灯光设备108将显示绿色以允许需要使用跑道的飞机在第一时间即可进入跑道，提高了运行效率；当有飞机进入跑道或滑行道交叉口时，数据处理计算机107将根据飞机的进入位置、滑行速度判定飞机的运动状态，控制相应滑行道口的引导灯光设备108。When the landing aircraft begins to leave the runway, once the active detection equipment installed on the taxiway crossing confirms that the aircraft has departed, thedata processing computer 107 will determine that the runway is in an idle state at this time, and theguide lighting equipment 108 of all taxiway crossings entering the runway will display green To allow the aircraft that need to use the runway to enter the runway at the first time, the operating efficiency is improved; when an aircraft enters the runway or taxiway intersection, thedata processing computer 107 will judge the movement of the aircraft according to the entry position and taxiing speed of the aircraft state, control theguidance lighting equipment 108 of the corresponding taxiway crossing.

任何时候当主动探测数据和被动式场面监视数据矛盾时，任何时候出现运动物体违反引导灯光信号进入跑道或滑行道时，数据处理计算机107都将自动管制员处置不安全事件。Whenever there is a contradiction between the active detection data and the passive scene monitoring data, and any time when a moving object enters the runway or taxiway in violation of the guiding light signal, thedata processing computer 107 will automatically handle the unsafe event by the controller.
