Description of the invention: [Technical field of invention] With the different inspection number, "reduction of the report is in the 7-domain of large traffic volume [previous technology] 】 In the past, the human or dangerous object system refers to the person who happened to be born in Wei, and when the inappropriate warning is expected to be lost, the warning signal 'for example' is blown by the wind. Newspapers or clothes, lost animals (for example, dogs and birds), etc. s The sensitivity of this kind of intrusion to non-effective objects is mixed in the _ zone. For example, in the railway station's railroads, there is also a traffic jam. A large number of passengers wait for the bus on the platform and get off the train. This inappropriate alarm or false alarm _ event may cause Yang's train service to be interrupted. On the other hand, the person Qian Tongbina holds a high crane, #effective people and dangerous objects can accurately issue an alarm when invading. The current train system is usually automatically controlled, no need for drivers and platform administrators, and 1380245 / W to get money for five shirts to safely hide as a light full-length shirt for the slaves to be a slave to the eight-point (four) (four) _ at the place. Especially in the case of miscellaneous, it occurs in the __ ϋ ϋ (4) object (four) risk, slave _ moment, the intrusion detection system only has a few seconds to warn and. Do not hit the fallen passengers. The way to solve the problem is to artificially isolate the platform from the rails with a door with a daring. Safety _, the door is opened, and the door of the train is also connected with the moon. This kind of, and the need to install expensive equipment, so that the platform and the train door can be linked together, one-to-one operation, 'a test of pottery, miscellaneous - come, two pastes _ enough to match the length of the train, which The number of cars and models may vary. However, this physical method does not warn the iron of the presence of other objects that may disrupt the train, cause the train to fulfil or damage the train. * Laser scanners are also used as detectors for intrusion detection systems as disclosed in the patents of U.S. Patent Nos. 4,949,074 and 6,278,373. The laser scanning of the second space (10) was used for crying 2 and the culvert car (four) Na. Mosquito, (10) The laser scan is very mussel* and in order to cover the average length of the platform at least four scans need to be installed on the outside or outdoors [« find cover - New job ^ this wire is outside the wire on the outside of the part of the scanner The laser is affected by its effects, in which false alarms are easily emitted, and heavy rain and intense sunlight can affect the sensor. Another method is to use closed-circuit television (10) v), that is to say, including static kneading and camera 'such as surveillance or photographic sensors such as US Patent No. 6, Micro_ and 6 Eagle, like ^ 6 1380245 The exposed position, the imaging needle in the discriminating of serious intrusion has a limited effect. This is because the camera acts as a sensor for visible light and is highly sensitive to changing weather and daylight conditions. The US patent number 6, 297, 844 deletes the ship's camera. In the case of U.S. Patent No. 5,825,412, the stereo camera detection system calculates the pixels of the invading object and is a two-dimensional (10) object capture. Correspondingly, we can think that the newspaper is a: the object has the SF, the frequency, and (4) the weather caused by the fineness of the object and the fluctuating sunlight. Any discussion of literature, equipment, statutes and knowledge in this manual is used to explain the contents of the invention. In the relevant fields of Singapore or other places, in the context of this disclosure and the scope of the patent application, it should not be "the right kind of pre-technical foundation or the correct shackles of the period and content." Knowledge of the literature. All statements regarding the date and the contents of the contents of these documents are based on the applicant's existing materials and are not a substitute for the nature of these documents. ♦ Summary of the Invention The main object of the present invention is to facilitate the rigorous hard construction. And the combination of new difficult data processing logic overcomes the _. She rings the number of expensive induction hardware caused by sensors that detect electromagnetic spectrum in two different ranges. Group sensed signal. The third object of the present invention is to reduce the incidence of false alarms, and to combine the two sets of sensors from two applications to describe the perimeter determination to reduce the actual area to be scanned for intrusion. A fourth object of the present invention is to provide a three-dimensional (10) scan of an invading object, 7 sufficient to cover the length of the entire table (10).

For example, the successor will issue an alarm or activate the safe shutdown function. Any other laser scanner other than the LMS 291 and SIG_D LS-4 can be used as long as it has a sub-scan range and a frequency of no less than & Preferably, the laser beam is directed from the edge of the platform (10) by about two centimeters, so that it does not detect those foxes and invade the sorrow (8). With such an arrangement, only those dangerous passengers near the edge of the platform (10) are reported to have a gap of two centimeters from the edge of the platform (10) to ensure that the train enters or the platform is avoided. (6) A false alarm is issued. The second-degree space is shot from the top to the bottom, providing a scan of approximately (10) degrees s 54G Hz (2) (Hz). The touch SI is shown in the side view of the second A to the second c, and the train is omitted here. View 12 丄:)0UZ4;) From the structure of the laser scanner above, it is obvious that our method is to use the laser scanner X lunar edge (12) to create a virtual wall (22) to define a to be protected Around the control area, it is expected to control the yellow line area of the platform ((8) and the entire length of the track (20) along the platform (10). Reading by using such a fact to reduce the scope of monitoring, because of the invasion of Congdao The district (10) is likely to be only Weiyuetai (10), and it must be a virtual wall (10). u I have detected the object or person who invaded the virtual wall (22) on the leftover system ("). This method effectively reduces the number of inductives required for the range and age to be monitored. About. Xuandi-H is a U-Machine, which can be a camera or a camera. - The stereo cameras (30a, 30b) (including CCTV, CCTV) are placed at each end of the platform (10), and the cats are allowed to be placed under the roof (32) to prevent wind and sun.

This can be achieved by the following steps. Wei selects the area on the image that is considered to be the orbital area. Each of the pixels in the obscured region is scored as a second-degree work in real space. . The result of this-drawing is 'the actual position of an object (u is the position occupied by the track area (Xi, Yi)) can be estimated. The position sensor is referred to the figure - 'except the above sensor' The laser scanner (14, (8) and the closed-circuit television stereo camera (30a, 30b) outside the 'third sensor can also be built into the system as the best real face of the present invention. The third sense is the position The inductor, which is preferably an inductive device, that is, a device that inductively generates a current as a signal when an iron or non-ferrous metal object is detected, the induction coil of which can sense the signal. The device includes the TL-L series of long-range induction proximity sensors manufactured by Omron Electronics LLC, which has an effective length of up to 1 mm for iron and aluminum (non-ferrous) targets. Inductive distance. Another sensor is the Osiprox-sensing proximity sensor manufactured by Schneider Electric Industries S_A., which has a long-term sensing distance of 60 gongs. 80245 As shown in the figure, the preferred embodiment has three types of sensors, that is, the position sensors (40a 4Gb 4Qc) in addition to the laser scanners (14, 16) and the closed-circuit television stereo camera. 40d'4Ge) is preferably arranged along the rails to detect the arrival, departure and docking of the train. The figure shows five such position sensors (Gam, Los, E, e), green iron The interval is set, in which three position sensors (10) fly, etc. are placed to sense the position of the train ^ on the platform, while the other two position sensors (10), surgery) are set to φ The ends of the obey are preferably 1 ftm away from each end of the platform, so that they leave the station to arrive at the train and leave the station. Preferably, these position sensors are placed above the rail (10) (e.g., mounted on a rail roof). The secret amount of the sensor is the length of the station and is sufficient to cover the length of the train (depending on the number of cars 1). As shown in the second and second c-pictures, the position sensor (10) detects the position of the single-car (10), and the two position sensors (40b '40c) are sufficient to detect the double compartment. The location of the train (52). The virtual wall (10) formed by the laser scanners (1), (6) can be constructed to ignore the "holes along certain segments of the virtual wall (22) or along the virtual thin" setting "open, In the window area, the position sensor (10), lion, _ above 'detects the train that has been docked along the platform. These "open, window area can correspond to the door of the train" so that the movement of the passengers up and down the train will not be regarded as It is the invasion of the virtual wall (10). Three-dimensional (3D) sweep; fe In the present invention, the stereo camera provides a three-dimensional spatial scan using a method established by calculating a stereo disparity map (9). This unequal earning spanty (four) can be obtained by subtracting the same-position two different pictures from different camera positions in 16 1380245. Each picture consists of a numerical matrix, 岐岐 _ _ _ (4). The values on the elements of the class are the same points that are related to each other. For example, the two cameras see the figure to calculate the relevant position of the same point in the two images, and obtain the geometrical principle through Yunxian.
