Description

检测毒品、 ***物及金属的行人安全检査门  Pedestrian safety inspection door for detecting drugs, explosives and metals
技术领 Technical collar
本发明涉及一种安全检査门，尤其涉及一种能够同时检查金属危险品和毒品 /*** 物的安全检査门。 背景技术  The present invention relates to a security inspection door, and more particularly to a security inspection door capable of simultaneously inspecting metal dangerous goods and drugs/explosives. Background technique
自 "911 "事件以来， 反恐成为全球范围的共同话题。 美国、 俄罗斯、 英国、 埃 及、 西班牙、 印尼、 印度等国均发生过恐怖事件， 美国为此还发动了二场战争。 恐怖 分子利用 "***"袭击成为一种重要的破坏方式， 对老百姓的安全生活和社会的稳定 构成了巨大的威胁。 但是目前市场上流行的针对行人检査的安全门， 一般只能探测磁 性金属， 对非磁性物体无能为力。 因此对***物和毒品， 普通安全门无法识别， 这对 安全检查来说， 无疑是一个重大漏洞。  Since the "911" incident, anti-terrorism has become a common topic on a global scale. The United States, Russia, the United Kingdom, Egypt, Spain, Indonesia, India and other countries have had terrorist incidents. The United States has also launched two wars. The use of "human bomb" attacks by terrorists has become an important form of destruction, posing a huge threat to the safe life of the people and the stability of society. However, the safety gates currently on the market for pedestrian inspection generally only detect magnetic metals and are incapable of acting on non-magnetic objects. Therefore, for explosives and drugs, ordinary security doors are not recognized, which is undoubtedly a major loophole for security inspections.
随着毒品、 ***物探测 （IMS ) 技术的发展， 对行人携带的毒品、 ***物等可疑 微粒检测成为可能。 最近几年， 国外专家对应用 IMS技术的门式行人检查技术进行了 很多研究， 并申请了多项专利。 如： EP1286151A1 , US5915268A1 , US6073499A1及 US2001049926A1 等等。 在这些专利中， 为了便于收集气流， 提出了多种门的结构； 为了提高收集效率， 有的提出了浓缩思想 （如 US6073499A1等）； 为了把人体衣物中 携带可疑微粒吹落下来， 由幵始的用连续气流吹被检查的行人（如 US2001049926A1 ), 到又加入喷高压气体的喷头来吹打衣物， 吹气的气流和喷头喷气的方向， 或向上方， 或向下方， 想尽了各种办法 （如 EP1286151A1 , US5915268A1和 US6073499A1 )。  With the development of drug and explosives detection (IMS) technology, it is possible to detect suspected particles such as drugs and explosives carried by pedestrians. In recent years, foreign experts have conducted a lot of research on the door-type pedestrian inspection technology using IMS technology, and applied for a number of patents. Such as: EP1286151A1, US5915268A1, US6073499A1 and US2001049926A1 and so on. In these patents, in order to facilitate the collection of airflow, various door structures have been proposed; in order to improve the collection efficiency, some have put forward the idea of concentration (such as US6073499A1, etc.); in order to blow suspicious particles in human clothes, from the beginning Pedestrians (such as US2001049926A1) that are inspected by continuous airflow, and then sprayed into the nozzles that spray high-pressure gas to blow the clothes, the direction of the airflow and the direction of the nozzle jets, or upward, or downward, to find various ways (eg EP1286151A1, US5915268A1 and US6073499A1).
在检测金属方面，专利 CN1834690提出了一种通过式金属探测***，通过双发双 收式天线和相应的电路、 软件等改善了检测磁场分布不均匀的缺陷， 提高了区分金属 物的能力。 专利 CN1802675A ( WO2004/097456 ) 提出了一种带有轻便结构的金属探 测器， 通过设置重载负荷循环和脉冲工作模式， 使它能够较长时间利用电池或交流电 源运行。  In the detection of metal, the patent CN1834690 proposes a through-metal detection system, which improves the detection of uneven magnetic field distribution through the double-shot and double-receiver antenna and the corresponding circuit and software, and improves the ability to distinguish metal. Patent CN1802675A (WO2004/097456) proposes a metal detector with a lightweight structure that allows it to operate with a battery or an AC source for a longer period of time by setting a heavy duty duty cycle and a pulsed mode of operation.
但由于种种原因， 目前市场上尚未发现同时检测毒品 /***物和金属的装置。 发明内容 因此， 本发明旨在提供一种能够同时检査金属危险品和毒品 /***物的安全检查装― 置。 However, for various reasons, devices for simultaneous detection of drugs/explosives and metals have not been found on the market. Summary of the invention Accordingly, the present invention is directed to a safety inspection apparatus capable of simultaneously inspecting metal dangerous goods and drugs/explosives.
本发明提供了一种检测毒品、 ***物及金属的行人安全检查门， 包括金属探测子 ***和毒品 /***物探测子***， 所述金属探测子***串联地安装在所述毒品 /***物 探测子***上， 其中， 所述安全检查门设置有隔离装置， 所述隔离装置使所述金属探 测子***和所述毒品 /***物探测子***之间相互隔离、 互不干扰。  The invention provides a pedestrian safety inspection door for detecting drugs, explosives and metals, comprising a metal detection subsystem and a drug/explosives detection subsystem, wherein the metal detection subsystem is installed in series on the drug/explosive substance detection The subsystem, wherein the security inspection door is provided with an isolating device, wherein the metal detecting subsystem and the drug/explosives detecting subsystem are isolated from each other and do not interfere with each other.
本发明首次将金属探测子***和毒品 /***物探测子***组合在一起形成一种新 颖的安装检查门， 从而能够同时检査金属危险品和毒品 /***物。 另外， 本发明还设置 有使金属探测子***和毒品 /***物探测子***之间相互隔离、 互不干扰的隔离装置， 从而提高了检测的可靠性和准确性。 附图说明  For the first time, the present invention combines a metal detection subsystem and a drug/explosive detection subsystem to form a new installation inspection door that enables simultaneous inspection of metal dangerous goods and drugs/explosives. In addition, the present invention is also provided with an isolating device for isolating the metal detecting subsystem and the drug/explosive substance detecting subsystem from each other, thereby improving the reliability and accuracy of the detecting.

图 1 显示本发明的具有金属探测子***和毒品 /***物探测子***的安全检查门 的整体结构立体图。图 6显示本发明的具有金属探测子***和毒品 /***物探测子*** 的安全检查门的俯视图。  BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view showing the overall structure of a security inspection door having a metal detecting subsystem and a drug/explosive detecting subsystem of the present invention. Figure 6 shows a top view of a security inspection door of the present invention having a metal detection subsystem and a drug/explosive detection subsystem.
如图 1所示， 安全检査门包括金属探测子*** 31和毒品 /***物探测子*** 30, 其中毒品 /***物探测子*** 30串联地安装在金属探测子*** 31的入口上，从而组成 一个完整的安全检査门。 当然， 毒品 /***物探测子*** 30也串联地安装在金属探测 子*** 31的出口上。  As shown in FIG. 1, the security inspection door includes a metal detection subsystem 31 and a drug/explosive detection subsystem 30, wherein the drug/explosive detection subsystem 30 is mounted in series on the inlet of the metal detection subsystem 31 to constitute A complete security check door. Of course, the drug/explosive detection subsystem 30 is also mounted in series on the outlet of the metal detection subsystem 31.
如图 1所示， 在金属探测子*** 31的入口处的上部设置有指示灯 25， 该指示灯 25用于指示被检査行人所处几种状态： 正在检查中 （黄灯）； 空闲 （绿灯）； 报警 （红 灯)。 As shown in FIG. 1, an indicator light 25 is disposed at an upper portion of the entrance of the metal detecting subsystem 31, and the indicator light 25 is used to indicate the status of the pedestrian being inspected: in the middle of inspection (yellow light); idle (green light); alarm (red light).
如图 1所示， 在毒品 /***物探测子*** 30的外表面上设置有作为用户终端的显 示器， 用于显示检测结果。  As shown in Fig. 1, a display as a user terminal is provided on the outer surface of the drug/explosive detection subsystem 30 for displaying the detection result.
如图 1所示，本发明中的金属探测子*** 31是通过发射电磁波来探测金属材料的 探测***， 其可采用釆用现有技术中适用的任一种金属探测***。 因此本文省略金属 探测子*** 31的具体结构的说明。  As shown in Fig. 1, the metal detecting subsystem 31 of the present invention is a detecting system for detecting a metallic material by emitting electromagnetic waves, which can be applied to any metal detecting system applicable in the prior art. Therefore, the description of the specific structure of the metal detecting subsystem 31 is omitted herein.
由于金属探测子*** 31和毒品 /***物探测子*** 30相互邻接在一起，因此毒品 /***物探测子*** 30中的许多金属部件（例如金属壳体、 金属管线等）， 会对金属探 测子*** 31造成干扰， 严重影响金属探测子*** 31的探测结果。 具体地， 当金属探 测子*** 31工作时，其发射的电磁波必然会漫射到毒品 /***物探测子*** 30的上述 金属部件上， 然后返回到金属探测子*** 31中， 这样就导致金属探测子*** 31出现 误报。  Since the metal detection subsystem 31 and the drug/explosive detection subsystem 30 are adjacent to each other, many metal components (eg, metal casings, metal pipes, etc.) in the drug/explosive detection subsystem 30 will be metal detectors. System 31 causes interference that severely affects the detection results of metal detection subsystem 31. Specifically, when the metal detecting subsystem 31 is in operation, the electromagnetic waves emitted by it are necessarily diffused onto the above-mentioned metal parts of the drug/explosive detection subsystem 30, and then returned to the metal detecting subsystem 31, thus causing metal detection. Subsystem 31 has a false positive.
而且， 由于毒品 /***物探测子*** 30中还存在许多电磁波干扰源（例如压缩机、 风机、 电磁阀等）， 因此这些电磁波干扰源发射的出的电磁波同样会进入金属探测子系 统 31中， 对金属探测子*** 31产生干扰。  Moreover, since there are many sources of electromagnetic interference (such as compressors, fans, solenoid valves, etc.) in the drug/explosive detection subsystem 30, the electromagnetic waves emitted by the electromagnetic interference sources also enter the metal detection subsystem 31. Interference is caused to the metal detection subsystem 31.
为了避免毒品 /***物探测子*** 30对金属探测子*** 31干扰，如图 1和图 6所 示， 在金属探测子*** 31 的外周侧设置有吸波材料 21 (对应于本发明中的一种隔离 装置）， 该吸波材料 21具有吸收金属探测子*** 31发射的、传播到外部区域的电磁波 和在金属探测区域外所产生的电磁波或回波， 以减弱和防止金属探测区域外的电磁波 或回波进入金属探测区域内。具体地， 该吸波材料 21能够吸收通过金属探测区域交界 面的电磁波并将它转化成热能，从而减少外界电磁波或回波对金属探测子*** 31的影 响。  In order to prevent the drug/explosive detection subsystem 30 from interfering with the metal detection subsystem 31, as shown in FIGS. 1 and 6, an absorbing material 21 is provided on the outer peripheral side of the metal detecting subsystem 31 (corresponding to one of the present invention) The absorbing material 21 has an electromagnetic wave emitted by the absorbing metal detecting subsystem 31 and propagating to an external region and an electromagnetic wave or echo generated outside the metal detecting region to attenuate and prevent electromagnetic waves outside the metal detecting region. Or echo into the metal detection area. Specifically, the absorbing material 21 is capable of absorbing electromagnetic waves passing through the interface of the metal detecting region and converting it into heat energy, thereby reducing the influence of external electromagnetic waves or echoes on the metal detecting subsystem 31.
另一方面，由于金属探测子*** 31和毒品 /***物探测子*** 30的各种信号线都 必须连接到总控制柜 14, 因此两个子***之间很容易出现信号串扰。  On the other hand, since the various signal lines of the metal detecting subsystem 31 and the drug/explosive detecting subsystem 30 must be connected to the main control cabinet 14, signal crosstalk easily occurs between the two subsystems.
为了避免两个子***之间出现信号串扰， 如图 6所示， 金属探测子*** 31的控制 器 22先通过信号线 20与信号隔离器 10 (对应于本发明中的另一种隔离装置） 相连， 然后信号隔离器 10通过信号线 12与总控制柜 14内的计算机 13进行通信。 具体地， 本实施例中的信号隔离器 10是设置在金属探测子*** 31的信号线、 电源线和地线上 的滤波器、 去耦合器及光电隔离器等。 为了进一步防止金属探测子*** 31和毒品 /***物探测子*** 30的信号线的相互 干扰， 两个子***的信号线应当尽量分幵走线， 即在空间上应当尽量分开。 在信号线 交叉时， 也要按十字交叉的方式减少互扰。 In order to avoid signal crosstalk between the two subsystems, as shown in Figure 6, the controller 22 of the metal detection subsystem 31 is first connected to the signal isolator 10 (corresponding to another isolation device in the present invention) via signal line 20. The signal isolator 10 then communicates with the computer 13 within the overall control cabinet 14 via signal lines 12. Specifically, the signal isolator 10 in this embodiment is a filter, a decoupler, an opto-isolator, or the like disposed on a signal line, a power line, and a ground line of the metal detecting subsystem 31. In order to further prevent the mutual interference of the signal lines of the metal detecting subsystem 31 and the drug/explosives detecting subsystem 30, the signal lines of the two subsystems should be routed as far as possible, that is, they should be separated as much as possible in space. When the signal lines cross, the crosstalk is also reduced in a crisscross manner.

下面详细说明本发明的工作原理。  The working principle of the present invention will be described in detail below.
1. 毒品 /***物探测子*** 30的工作原理  1. How the drug/explosives detection subsystem 30 works
如图 2所示， 空气压缩机 1提供高压气体， 压力 0. 2〜0. 8MPa, 最好 0. 5 MPa左 右。 通过喷气嘴进气管 5给喷气嘴 8提供高压气体， 每个喷气嘴 8都通过一个电磁阔 9控制其喷气 /关闭状态。 ***控制计算机 13通过总控制柜 14和气路控制信号线 29 控制电磁阔 9、 空气压缩机 1、 载气气流风机 2等部件开和关的时序。 空气压缩机 1和 载气气流风机 2吸入的空气来自进气口 3。  As shown in Fig. 2, the air compressor 1 is provided with a high pressure gas, a pressure of 0. 2~0. 8MPa, preferably 0. 5 MPa left and right. The air nozzle 8 is supplied with high-pressure gas through the air nozzle inlet pipe 5, and each of the air nozzles 8 controls its air-jet/close state by an electromagnetic width. The system control computer 13 controls the timing of opening and closing of components such as the electromagnetic wide 9, the air compressor 1, and the carrier gas flow fan 2 through the main control cabinet 14 and the pneumatic control signal line 29. The air taken in by the air compressor 1 and the carrier gas flow fan 2 comes from the intake port 3.
同一层的喷气嘴 8—般同时开 /关； 不同层的喷气嘴 8分时开 /关， 一般自上而下 依次开或关， 等每一层喷气嘴 8都喷完一次后， 再自上而下循环， 直到喷气过程结束； 其开关时序由总控制柜 14发出， 通过控制每个喷气嘴 8后面的电磁阀 9来实现。  The air nozzles 8 of the same layer are normally turned on/off at the same time; the air nozzles 8 of different layers are turned on/off in a time-sharing manner, and are generally turned on or off from top to bottom, and after each layer of the air nozzles 8 is sprayed once, then The cycle is repeated up and down until the end of the jetting process; its switching sequence is issued by the main control cabinet 14 by controlling the solenoid valve 9 behind each of the air nozzles 8.
在最上层 A的喷气嘴 8第 1次开始工作的同时， 载气气流风机 2也开始工作， 给 如图 5所示的风刀 6供气， 图中给出 4个大风刀 6和 2个小风刀 6。 气流从风刀 6的 风刀吹气口 7吹出， 形成载气气流， 其流动方向如载气气流流动方向 28所示。 载气气 流的作用是把由喷气嘴 8吹下来的可疑微粒带动到吸气口 19。 测试空间 27的载气气流被吸气风机 16吸入吸气口 19。 进入吸气口 19的含有可 疑微粒的气流通过预凝器 18时， 可疑微粒被吸附到预凝器 18中， 过滤后的气流， 经 过吸气风机 16、 排气管 15、 排气口 11排到外面的大气之中。 在解吸附的过程中， 预 凝器 18把吸附到的可疑微粒解释出来， 被毒品、 ***物探测器 （IMS) 17吸入进行分 析， 废气经过排气管 15、 排气口 11排到外面的大气之中。 While the air nozzle 8 of the uppermost layer A starts working for the first time, the carrier gas flow fan 2 also starts to work, supplying air to the air knife 6 as shown in Fig. 5, and four large wind blades 6 and 2 are shown in the figure. Small wind knife 6. The air flow is blown from the air knife blowing port 7 of the air knife 6, forming a carrier gas flow, the flow direction of which is shown as the carrier gas flow direction 28. The role of the carrier gas stream is to drive the suspect particles blown down by the air nozzle 8 to the suction port 19. The carrier gas stream of the test space 27 is sucked into the intake port 19 by the suction fan 16. When the airflow containing the suspected particles entering the suction port 19 passes through the pre-condenser 18, the suspect particles are adsorbed into the pre-condenser 18, and the filtered airflow passes through the suction fan 16, the exhaust pipe 15, and the exhaust port 11 Go to the outside atmosphere. During the desorption process, the pre-condenser 18 interprets the adsorbed suspicious particles, is inhaled by the drug, explosives detector (IMS) 17, and is exhausted through the exhaust pipe 15 and the exhaust port 11 to the outside. In the atmosphere.
由毒品、 ***物探测器 （IMS ) 17探测的数据通过数据线路送到总控制柜 14， 再 送入***控制计算机 13进行分析， 结果在用户终端 24和指示灯 25上显示。  Data detected by the Drugs, Explosives Detector (IMS) 17 is sent to the main control cabinet 14 via the data line and then sent to the system control computer 13 for analysis, and the results are displayed on the user terminal 24 and the indicator light 25.
开始检査时， 指示灯 25显示空闲 （绿灯亮）， 被检査的行人进入测试空间 28的 指定位置站好； ***幵始喷气、 吹气、 收集气体， 然后送到毒品、***物探测器（IMS ) 17探测， 并最终由***控制计算机 13给出分析结果。 如果发现有毒品、 ***物的痕 迹， 则发出警报， 同时指示灯 25报警 （红灯闪烁）； 如果没有发现可疑物， 则本次毒 品、 ***物检査结束， 指示灯 25是否何种状态， 还要继续等待下一步的金属探测子系 统的分析结果。 直到最后结果出来后， 如果没有可疑物， 指示灯 25才显示空闲 （绿灯 亮）， 等待下一个被检人的进入。  When the inspection starts, the indicator light 25 shows idle (green light is on), and the pedestrian being inspected enters the designated position of the test space 28; the system starts to jet, blow, collect gas, and then sends it to the drug and explosives detector. The (IMS) 17 detects and finally the analysis result is given by the system control computer 13. If there are traces of drugs or explosives, an alarm will be issued, and the indicator light 25 will be alarmed (red light flashes); if no suspicious objects are found, the drug and explosives check is over, and the indicator light 25 is in any state. Continue to wait for the analysis results of the next metal detection subsystem. Until the final result comes out, if there is no suspicious object, the indicator light 25 will display idle (green light), waiting for the next person to enter.
2. 金属探测子*** 31工作原理  2. Metal detection subsystem 31 working principle
当毒品、 ***物检查子*** 30停止喷气后， 被检行人可以继续前进通过金属检 查分*** 23。 探测出来的信号将通过金属检査子*** 31的控制器 22、 信号线 20， 传 到信号隔离器 10, 然后经信号隔离器 10至总控制柜信号线 12、 总控制柜 14， 与*** 控制计算机 13通信。 经过***控制计算机 13通信分析后， 如果发现可疑物， 立即报 警， 同时指示灯 25报警（红灯闪烁）。 如果数据正常， 还需等待毒品 /***物探测子系 统 30的数据分析结果， 才能得出综合的结果， 以决定***是否报警。  After the drug and explosives inspection subsystem 30 stops the jet, the inspected pedestrian can proceed through the metal inspection subsystem 23. The detected signal will pass through the controller 22 of the metal inspection subsystem 31, the signal line 20, to the signal isolator 10, and then through the signal isolator 10 to the main control cabinet signal line 12, the overall control cabinet 14, and system control. The computer 13 communicates. After the communication analysis by the system control computer 13, if a suspicious object is found, the alarm is immediately reported, and the indicator light 25 is alarmed (red light flashes). If the data is normal, wait for the data analysis results of the drug/explosive detection subsystem 30 to arrive at a comprehensive result to determine if the system is alerting.
在毒品 /***物探测子*** 30采样结束后， 毒品、 ***物探测器 （IMS ) 17分析 数据尚需几秒钟， 这时金属探测分*** 23可同步探测分析。直到最后的综合结果出来 后， 如果没有可疑物， 指示灯 25才显示空闲 （绿灯亮）， 等待下一个被检人的进入。  After the drug/explosive detection subsystem 30 has been sampled, it will take a few seconds for the drug and explosives detector (IMS) 17 to analyze the data, at which point the metal detection subsystem 23 can simultaneously detect the analysis. Until the final combined result comes out, if there is no suspicious object, the indicator light 25 will be idle (green light), waiting for the next person to enter.
总之， 二个探测分***结合一起， 可以同时完成检査行人携带的毒品、 ***物和 金属等任务， 提高了检査效率。 尽管已经示出和描述了本发明的实施例， 对于本领域的普通技术人员而言， 可以 理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行变化， 本发明的范 围由所附权利要求及其等同物限定。  In short, the two detection subsystems can be combined to perform tasks such as checking drugs, explosives and metals carried by pedestrians, and improve inspection efficiency.
