Description

  The present invention relates to a security system, for example, a system useful for ensuring safety against dangerous goods by detecting whether or not dangerous goods are present in baggage, cargo, suspicious objects, and the like. In this specification, dangerous materials refer to explosives including explosives, poisonous gases, flammable substances, and the like.

  In general, in places where many people gather, such as airports and event venues, in order to ensure the safety of passengers and event participants, it is widely performed to check baggage etc. using X-rays, metal detectors, etc. It is. In addition, when there is a possibility that dangerous materials such as explosives are set up, the presence of dangerous materials must be inspected, but the inspection device for dangerous materials has not yet become widespread. At present, if there is a possibility that dangerous materials such as explosives are installed, an expert will be dispatched to confirm the presence of dangerous materials. Such dangerous goods inspections are also requested for inspection of suspicious items in parcel delivery package inspections, bank safe deposit boxes and the like.

  As a typical method for detecting a dangerous substance, a gas chromatographic method and a mass spectrometry method are known. Each method collects (samples) a small amount of air that leaks from baggage or suspicious objects, analyzes the collected air (sample gas), and detects the presence of substances that constitute dangerous substances such as explosives. Is.

  In the gas chromatograph method, after heating a column made of silica or iron or glass filled with an adsorbent and injecting a sample gas, a carrier gas such as nitrogen, helium or hydrogen is passed. The principle is that each component constituting the sample gas is separated and flows out of the column due to a difference in boiling point, a difference in affinity with the inner surface treatment substance or the packing material, or the like. That is, since the moving speed of each component contained in the sample gas in the column is different, each component is separated and flows out from the column. In this way, the thermal conductivity method or the like of the component that separates and flows out is measured by an appropriate method, the mixing state of the sample is known, and the component is analyzed.

Further, RDX and TNT, which are representative explosives, are generally detected by detecting NO ₂ constituting them. However, NO ₂ is a part of explosives, and it is difficult to understand the structure of the compound itself. Therefore, reference data is acquired in advance and a relative comparison with the outflow time or the like is performed to determine whether or not it is an explosive and its type. The series of detection processes takes about several minutes, and much effort is required for maintenance of the apparatus such as acquisition of reference data for relative comparison.

  The mass spectrometry method is a method in which a sample gas is ionized and the mass of an ion (more precisely, a value m / z obtained by dividing the mass m of the ion by the charge z) is measured by a mass spectrometer disposed in a vacuum. The mass spectrometer includes a quadrupole mass spectrometer and an ion trap mass spectrometer.

  The quadrupole mass spectrometer is a mass spectrometer composed of four rod-shaped electrodes, and an electric field is formed by applying a DC voltage and a high-frequency voltage superimposed on each electrode. The ionized sample gas molecules are introduced into the electric field, and the ions passing through the electric field undergo complex vibrations three-dimensionally, and only the ions having an m / z ratio according to the applied DC voltage and harmonic voltage. It is detected through the electric field. Other ions disappear when they collide with the electrode. Therefore, a spectrum can be obtained by scanning while keeping the ratio between the DC voltage and the harmonic voltage constant.

  On the other hand, an ion trap mass spectrometer is composed of two end cap electrodes and one ring electrode. When ionized sample gas molecules are introduced into the space between these three electrodes, the ions are confined (that is, trapped) in an electric field formed by a high-frequency voltage applied to the ring electrode. The trapped ions are emitted in order of mass by scanning another high-frequency voltage applied to the end cap electrode, and a spectrum can be obtained by detecting this. High sensitivity is achieved by a kind of integration effect that ions are stored in an electric field and released after a certain time (for example, on the order of several tens of milliseconds).

  By analyzing the mass spectrum data of the sample gas obtained in this way, the presence or absence of a dangerous substance such as an explosive is determined based on the presence or absence of a mass spectrum specific to the dangerous substance such as an explosive contained in the sample gas. , That kind can be identified. The time required for detection of explosives by this method is short (for example, 3 to 8 seconds). In particular, the mass spectrometry method is highly reliable, and only the ions (parent ions) unique to explosives are separated from the ion mixture, the parent ions are activated, and then fragment ions (daughter ions) derived from the parent ions. By applying an operation for detecting the multiplex analysis in which mass spectrometry is repeatedly performed, the reliability is further improved.

By the way, although inspection of baggage at airports and event venues, inspection of parcels of parcel delivery, inspection of suspicious items at bank safe deposit boxes, etc., detection of dangerous goods is requested, but it has not been widely used. The reason is considered to be caused by the following points.
(1) Problem of detection time Baggage inspection is generally performed in the process of loading and transporting baggage on a belt conveyor, but there is a problem that the inspection site becomes congested if it takes too much time to detect explosives. For example, in consideration of the conveyor speed (generally 12 m / s), it is desirable to complete the detection within a few seconds (for example, 8 seconds). From this point of view, the gas chromatograph method is not suitable because it takes too much time for detection. In this regard, the mass spectrometry method is preferable because it can be detected in a few seconds and has high reliability.
(2) Difficult to train personnel with specialized knowledge In baggage inspection at airports, etc., it is necessary to deploy a large number of explosives and other dangerous goods inspection devices in order to inspect a large number of baggage smoothly. Therefore, if specialized knowledge is required for handling dangerous goods inspection devices such as operation, maintenance, inspection, repair, improvement, and change, there are many difficulties in training personnel having specialized knowledge.
(3) Ensuring the safety of human bodies due to explosives, etc. When explosives are detected, there are problems with measures such as ensuring the safety of human bodies due to explosives. Conventionally, it will contact the public authorities (police station, fire department, etc.) that have jurisdiction and request the dispatch of specialized explosives disposal teams. In that case, since the treatment differs depending on the type, amount, form of explosives, and storage container for explosives, appropriate measures can be taken if highly accurate information can be obtained before the explosives treatment team is dispatched. I can expect. In addition, it would be more desirable if appropriate protective measures for the time being were quickly known.

  An object of the present invention is to improve the safety of society by improving the inspection speed and reliability of inspection of dangerous goods, making it easy to introduce a security system.

  The present invention solves the above problems by the following means.

  First, by adopting a system that detects a dangerous substance by mass spectrometry, the inspection speed is shortened (preferably several seconds (3 to 8 seconds)), and the introduction trouble related to the inspection time is solved. In particular, since a system that detects hazardous materials using two-stage multiplex analysis (MS1 / MS2) is adopted, the inspection can be completed if the result of MS1 is “No explosives”. The time can be shortened and it can contribute to avoiding traffic jams at the inspection site. Further, when the determination result of MS1 is suspicious, the analysis can be performed again by executing the analysis of MS2 with different analysis conditions, so that the reliability can be further improved.

  In addition, a security service business is established, which enables a service provider to perform operational management such as facility management such as maintenance, inspection, adjustment, repair, improvement, and change of the entire security system including the dangerous goods inspection device. This makes it easier for the user to introduce a security system. In other words, in the case of the conventional form in which the inspection site administrator purchases the security system as an asset, even if the initial equipment cost can be reduced using a lease, etc., the personnel required for equipment management The burden of expenses related to securing, training and other operation management is large. In this regard, by creating a security service business that specializes in operation management of security systems, at least the burden associated with equipment management such as maintenance and inspection can be reduced. In addition, the security service provider can further reduce the burden on the user by dispatching human resources necessary for operation management and providing information.

  On the other hand, the security system is divided into a terminal system provided with at least a function necessary for the inspection of dangerous goods at the inspection site and a support system not necessarily required for the inspection site. Then, a security system is constructed by connecting them through a communication line such as a dedicated communication line or a public communication line (such as the Internet). In this case, for example, a necessary number of terminal systems are installed in one or a plurality of inspection sites, and a support system that supports these terminal systems is installed in a security service provider's office (for example, one place). Can be adopted.

  Various forms of security service business are possible. For example, a mode in which a user purchases a terminal system, a mode in which a security service provider grants a terminal system to a user free of charge, and the like can be considered. Depending on these forms, the security service provider may charge (charge) equipment costs such as maintenance, operation management, and other costs related to the service in addition to various costs related to the security system.

  When a period such as an event is limited, a form in which a security service provider grants a terminal system free of charge will be preferred. Regardless of the form, the security service provider is responsible for equipment management such as terminal system maintenance, inspection, adjustment, repair, improvement, and change, or personnel management and operation management that provides information. This makes it easy to introduce a security system.

  Specifically, a terminal system for inspecting dangerous goods equipped with mass analysis means is installed at the inspection site, and the presence and type of dangerous goods are determined based on the mass analysis data of the component to be inspected measured by the mass analysis means. A support system for judging is installed at the security service provider's office. Then, the terminal system and the support system are connected so as to be able to exchange information via a communication network, and the support system transmits a determination result of dangerous goods to the terminal system via the communication network. it can.

  Further, mass spectrometry means for analyzing the mass of the component to be inspected is provided to the user for a fee or free of charge, and the mass analysis data analyzed by the mass analysis means is received via a communication line, and the received mass analysis data and It is possible to collate with reference data related to dangerous goods and transmit the result of the comparison to the user.

  According to the present invention, it is easy to introduce a security system, and social safety can be improved. Further, the inspection speed can be improved and the reliability can be improved.

  Hereinafter, an embodiment in which the present invention is applied to explosives inspection will be described with reference to FIGS. FIG. 1 is a conceptual diagram of an embodiment of a security system according to the present invention, and FIG. 2 is a block diagram of an embodiment of the security system.

  As shown in FIG. 1, the security system includes a terminal system 1 installed in a baggage inspection area such as an airport as a user, and a support system 2 installed in a service company as a business of security service business. The terminal system 1 and the support system 2 are formed so as to be able to send and receive information to and from each other via the communication line 3. The terminal system 1 includes a gas suction pipe 5 that sucks a small amount of gas leaking from the baggage 4 to be inspected together with surrounding air, and a display unit 15 that displays information such as inspection results of dangerous goods. Configured. In addition, an X-ray device 7 is provided in the inspection site, and an X-ray image of the baggage 4 conveyed on the belt conveyor 8 is photographed to see through metal or the like.

  With reference to FIG. 2, the configuration and operation outline of the security system will be described. The inspection target gas is guided to the gas sampling unit 11 of the terminal system 1 through the gas suction pipe 5. The gas sampled by the gas sampling unit 11 is guided to the mass analysis unit 12, and mass analysis of the sampling gas is performed. Mass analysis data from the mass analysis unit 12 is sent to the explosives determination unit (I) 14 via the calculation control unit 13. The explosive determination unit (I) 14 compares the mass spectrometry data with the reference data I, and determines whether or not explosive components are included in the sampling gas, and if the explosives are included, 1 The stage is determined (MS1). The determination result is output to the calculation control unit 13 and displayed on the display unit 15. In the case of a determination result that there is an explosive, the calculation control unit 13 sends a command to the mass analysis unit 12 to change the analysis conditions and perform the second-stage analysis. The second stage mass analysis data output from the mass analysis unit 12 is output to the communication line 3 via the communication unit 17 by the arithmetic control unit 13. As is well known, the communication unit 17 generates data to be transmitted in a predetermined transmission format, adds a destination address, and outputs it to the communication line 3. In addition, when the address on the communication line 17 is attached to the data on the communication line 3, the communication unit 17 takes in the data. In addition, it is preferable to provide a function of encrypting / decrypting data as necessary. Further, the arithmetic control unit 13 takes in an X-ray image of baggage from the X-ray device 7 and takes in weight data of baggage from the weighing device 8.

  The second-stage mass spectrometry data transmitted from the communication unit 17 of the terminal system 1 is taken into the communication unit 21 of the support system 2 via the communication line 3, and the explosives determination unit (II) via the calculation control unit 22. ) 23. The explosive determination unit (II) 23 compares the second stage mass spectrometry data with the reference data II, and whether or not explosives are contained in the sampling gas. The second stage is determined for the type (MS2). The determination result of the second stage is transmitted to the terminal system 1 via the arithmetic control unit 22 and the communication unit 21 and displayed on the display unit 15 of the terminal system 1. The communication unit 21 is configured to have the same function as the communication unit 17 of the terminal system 1. Further, the support system 2 includes a database 24, a treatment guide unit 25, and an input unit 26. As shown in FIG. 3, the database 24 includes data such as mass spectrum data (MS1), mass spectrum data (MS2), mass spectrometry data (MS1), mass spectrometry data (MS2), maintenance / management data, and billing data. Is stored.

  Here, an ion trap type mass spectrometer shown in FIG. 4 is applied to the mass analyzer 12 of the present embodiment. The mass analysis unit 12 includes a sample gas introduction unit 31, a decompression chamber 32, and a high vacuum chamber 33. The sample gas introduction unit 31 sucks the inspection target gas 30 from the inlet of the sample gas flow path 34 using a vacuum pump or the like. On the other hand, the needle electrode 35 is disposed so as to face the hole 36 opened in the sample gas flow path 34. The needle electrode 35 emits electrons by corona discharge and ionizes oxygen (primary ionization) in the atmosphere. If the gas 30 to be inspected contains a component specific to the explosive, the ionized oxygen reacts with molecules specific to the explosive and is ionized (secondary ionization). The ions specific to explosives thus generated under atmospheric pressure are guided to the decompression chamber 32 through the hole 37 opened in the sample gas flow path 34 and the hole 38 opened in the decompression chamber 32, and It is introduced into the vacuum chamber 33 through the hole 38. The ions specific to explosives introduced into the vacuum chamber 33 flow into the ion trap part 41 through the ion converging part 40. The ion trap portion 41 is composed of two end cap electrodes and one ring electrode. When ions of the gas to be inspected are introduced into the space sandwiched between these three electrodes, the ions are confined (that is, trapped) in an electric field formed by a high-frequency voltage applied to the ring electrode. ). The trapped ions are emitted in the order of mass by scanning another high-frequency voltage applied to the end cap electrode, and the spectrum can be obtained by detecting this by the ion detector 43. High sensitivity is achieved by a kind of integration effect that ions are stored in an electric field and released after a certain time (for example, on the order of several tens of milliseconds).

  By analyzing the mass spectrum data of the sample gas obtained in this way, the presence or absence of a dangerous substance such as an explosive is determined based on the presence or absence of a mass spectrum specific to the dangerous substance such as an explosive contained in the sample gas. , That kind can be identified. The time required for detection of explosives by this method is several seconds (for example, 3 to 8 seconds). In particular, a fragment derived from a parent ion by separating only ions (parent ions) unique to explosives from the ion mixture and colliding helium gas with the parent ions to convert the kinetic energy of the parent ions into internal energy. Reliability is further improved by applying multiplex analysis (MS / MS) for generating ions (daughter ions) and detecting daughter ions.

  That is, in the first stage (MS1) mass spectrometry, a mass spectrum related to ions (parent ions) specific to explosives is measured, and the presence or absence of explosives is determined based on the mass spectrometry data of MS1. In order to further improve the reliability, the mass spectrum of the daughter ions is measured in the second stage (MS2) mass spectrometry, and the presence or absence of explosives is determined based on the mass spectrometry data of the MS2, thereby improving the reliability. I am doing so.

  The detailed configuration and operation of the security system configured as described above will be described with reference to the flowcharts shown in FIGS. FIG. 5 shows a processing procedure of the terminal system 1, and FIG. 6 shows a processing procedure of the support system 2.

  The terminal system 1 starts a series of processes in response to an inspection start command input from the input unit 16 to the arithmetic control unit 13. The arithmetic control unit 13 sends a command to the gas sampling unit 11 to sample a predetermined amount of inspection target gas (S1). The sampling gas is flowed into the mass analyzer 12, and the mass analyzer 12 performs the first stage (MS1) mass analysis according to the procedure described in FIG. 4 (S2). By analysis of MS1, a mass spectrum of components constituting the sample gas is obtained as mass spectrometry data. For example, the mass analyzer 12 outputs mass analysis data of ion components (parent ions) unique to explosives. The calculation control unit 13 takes in the mass spectrometry data and sends it to the explosives determination unit (I) 14 (S3). The explosive determination unit (I) 14 has reference data I corresponding to a preset mass of an ion component (parent ion) unique to explosives. Then, the explosive determination unit (I) 14 compares the input mass spectrometry data with the reference data I, and determines the presence or absence of a matching component (S4). The determination result is displayed on the display unit 5 via the calculation control unit 13. When the determination result is “no explosive”, the arithmetic control unit 13 ends the process (S6).

  On the other hand, when the determination result is “there is an explosive”, the calculation control unit 13 sends a command to execute the second-stage (MS2) analysis to the mass analysis unit 12 (S6). In response to this, the mass analyzer 12 performs the analysis of MS2 (S7). Here, as described above, in the analysis of MS2, only the ion component (parent ion) in the ion mixture trapped in the analysis of MS1 is separated from the ion mixture, the parent ion is activated, and then the parent ion This is an operation for detecting fragment ions (daughter ions) derived from. Thereby, the reliability concerning determination of explosives can be improved.

  The mass spectrometry data of MS 2 is sent to the communication unit 17 via the control calculation unit 13. The communication unit 17 writes the MS2 determination execution command and the MS2 mass analysis data in the transmission format addressed to the support system 2, and outputs the result to the communication line 3 (S8).

  The MS 2 determination execution command and the mass analysis data transmitted to the support system 2 are received by the communication unit 21 of the support system 2 via the communication line 3. As shown in FIG. 6, when the support system 2 confirms reception of the MS2 determination execution command in the arithmetic control unit 22 (S11), the support system 2 takes in the mass spectrometry data of the MS2 and sends it to the explosives determination unit (II) 23 (S12). ). The explosive determination unit (II) 23 has reference data II corresponding to a preset mass of fragment ions (daughter ions) unique to explosives. Then, the explosive determination unit (II) 23 compares the input MS2 mass spectrometry data with the reference data II to determine whether there is a matching component (S13). The determination result is sent to the communication unit 21 via the arithmetic control unit 22, and the determination result of the MS 2 is written in the transmission format addressed to the terminal system 1 and output to the communication line 3 (S14). If the contract is predetermined, the MS2 determination report is registered together with the accounting data in the database 24 (S14). Depending on the contract, the billing data of the determination cost can be sent to the terminal system 1.

  Returning to FIG. 5, the determination result of MS2 transmitted to the terminal system 1 is received by the communication unit 17 of the terminal system 1 via the communication line 3 (S9). Then, the calculation control unit 22 displays the determination result of MS2 on the display unit 15 (S10). With this series of processes, the explosives inspection process ends. When the determination result of MS2 is “there is an explosive”, the function of the treatment guide described later operates.

  According to the security system described above, explosives are detected by the mass spectrometry method, so that highly reliable detection can be performed in a sufficiently short inspection time. In addition, since the system that detects explosives by two-stage multiplex analysis (MS1 / MS2) is adopted, if the result of MS1 is “No explosives”, the inspection can be terminated. The time can be shortened and it can contribute to avoiding traffic jams at the inspection site.

  In particular, since the explosives determination unit (I) 14 is provided in the terminal system 1, communication time with the support system 2 is unnecessary in the case of “no explosives”, which is effective in speeding up the inspection. . In addition, when the determination result of MS1 is suspicious, since the analysis of MS2 is performed and re-determination is performed, the reliability can be further improved.

FIG. 7 shows a treatment procedure when the determination result of MS2 is “there is an explosive”. In the figure, the processing block of the terminal system 1 is indicated by a single line, and the processing block of the support system 2 is indicated by a double line.
(S21)

When the terminal system 1 receives the determination result of “hazardous material” from the support system 2, the terminal system 1 sends a command to the X-ray device 7 and the weighing device 7, and the weight and the X-ray image of the baggage 4 of the inspection object ( Request transmission of records of morphological information) and collect those data. If there is no record, the weighing of baggage 4 and execution of X-ray imaging are requested. The collected weight and X-ray image are transmitted to the support system 2 via the communication unit 17. The transmission process of the communication unit 17 is the same as described above.
(S22)

  The communication unit 21 of the support system 2 receives the weight of the baggage 4 and the X-ray image and sends them to the calculation control unit 22. The arithmetic control unit 22 sends a command to the treatment guide unit 25 together with the weight of the baggage 4, the X-ray image, and the type of explosives as the determination result of the explosives determination unit (II) 23. Require the creation of guidance on The treatment guide unit 25 calculates the weight of the explosive from the weight of the baggage 4 and the X-ray image, and estimates the power of the explosion in consideration of the type of explosive. In this case, X-ray image pixels are analyzed to determine the presence or absence of a detonator such as a fuze or detonator. Based on the data obtained in this way, a guidance for handling measures for the baggage 4 is created. The created treatment guidance is transmitted to the terminal system 1 by the arithmetic control unit 22 via the communication unit 21. For example, the following contents are included in the treatment guidance.

(1) Information on the composition of explosives, its name (common name or common name)
(2) Treatment method Necessity of evacuation 2. Whether the inspection object needs to be stored in a protective container, etc. 3. Necessity for restraint of personal belongings Necessity of contacting and reporting to related organizations Whether these treatment guidance is necessary or not depends on the composition and type of explosives. Moreover, when a treatment is required, a priority order is given.
(S23, S24)

  The terminal system 1 receives the treatment guidance and outputs and displays it on the display unit 15. It can also be printed out. Thereby, the inspector can ensure the safety of the person and the like by taking evacuation and protective measures in accordance with the treatment guidance displayed on the display unit 15. If the inspection site is equipped with a protective device against explosion such as a protective shelter, the protective shelter can be automatically operated to cover the baggage containing explosives and isolate the person.

  By providing the treatment guide unit 23 in the support system 2 in this way, the user of the terminal system 1 can display the treatment guidance on the display unit 15 even if the expert knowledge about the explosives is insufficient. Can take corrective action.

In FIG. 8, the flowchart of the process sequence which manages the driving | running state etc. of the terminal system 1 is shown. In the figure, the processing block of the terminal system 1 is indicated by a single line, and the processing block of the support system 2 is indicated by a double line.
(S31)

The arithmetic control unit 13 of the support system 2 periodically collects state data including the operation of each unit in a normal driving state. Then, the collected operation state data is transmitted to the support system 2 via the communication unit 17.
(S32)
The support system 2 receives the operation state data of the terminal system 1 and stores it in the database.
(S33)

The arithmetic control unit 22 checks the operation state data of the terminal system 1 according to the maintenance / management data stored in the database 24, confirms whether there is an abnormality, and registers it in the database.
(S34, S35)

  When an abnormality of the terminal system 1 is found, an inspection / adjustment procedure corresponding to the abnormality stored in the maintenance / management data is extracted and transmitted to the terminal system 1. The terminal system 1 checks and adjusts the system in accordance with the sent inspection / adjustment procedure. If necessary, an inspector will be dispatched from the security service company.

  In this way, a user having the terminal system 1 can receive support from the support system 2 of the security service company even if his knowledge of operation management is insufficient, and can concentrate on the inspection work with peace of mind. .

  FIG. 9 shows a flowchart of the update process of the database 24. Explosives are basically of a typical type as described above, but usually, various modifications are often made. Therefore, it becomes necessary to change the analysis conditions of the reference data I, II and MS2 relating to the determination of explosives. Therefore, in order to cope with such a case, it is preferable to provide a database update function as shown in FIG. In the figure, the processing block of the terminal system 1 is indicated by a single line, and the processing block of the support system 2 is indicated by a double line.

  As shown in the figure, when the support system 2 obtains database update information from an explosive manufacturer or the like by online or other communication means (S41), the support system 2 updates the data in its own database 24 and the update data is transmitted to the terminal. If it is related to the system 1, a data update instruction is transmitted to the terminal system 1 (S42). In response to this, when the terminal system 1 receives the data update instruction, if the reference data I is changed, the terminal system 1 accesses the explosives determination unit (I) 14 and updates the reference data I. If the analysis conditions of MS1 or MS2 are changed, the mass analysis unit 12 is accessed and the analysis conditions are updated (S43). When the update is completed, an update completion report is transmitted to the support system 2 (S44). The support system 2 receives and confirms the database update completion report, and ends the processing (S45).

  Next, FIG. 10 shows a conceptual diagram of an embodiment of a security service business to which the security system of FIG. 2 is applied. As shown in the figure, in the present embodiment, a service company 51, which is one place of a security service provider, has a user 52, a detection system provider 53, an explosive maker 54, a related organization 55 such as a public organization, Combined in an organic relationship. When operating the terminal system installed at the inspection site of the user 52, the service company 51 supports administrative services such as various services for inspection, determination and treatment of dangerous goods (explosives), maintenance and inspection, In response to this, you will be charged for the contract. The service company 51 receives the database update information from the detection system provider 53 and pays the cost to the detection system provider 53. Further, the service company 51 receives a treatment system (for example, a protective device) for dangerous substances such as explosives from the explosive maker 54 and pays the purchase cost to the explosive maker 54. Further, the service company 51 notifies the related related organization 55 of the information related to the explosives, that is, the explosives identifying information such as the explosive detection information and the type and amount of explosives, in accordance with the provisions of the law.

  In this example, the detection system provider 53 provides the user 52 with the detection system of the terminal system and receives the purchase cost. The explosive maker 54 provides explosives information, samples, and the like to the detection system provider 53 as information relating to updating of the detection system database and improvement of the system. In contrast, the detection system provider 53 provides an explosive detection algorithm and database. Further, the explosive maker 54 receives provision of information on the explosives modified from the related organization 55 and changes various information and database changes to the service company 51 and the detection system provider 53 in order to reflect them in the security system. Notice.

  FIG. 11 is a block diagram showing another embodiment of the security system of the present invention, and FIGS. 12 and 13 are flowcharts showing the processing procedure. As shown in these figures, the present embodiment is different from the embodiments shown in FIGS. 2 to 9 in that the explosives determination unit (I) 14 of the terminal system 1 is moved to the support system 2. . The explosive substance determination unit (I) 27 of the support system 2 is not functionally different from the explosive substance determination unit (I) 14 at all.

  According to the present embodiment, as shown in the flowcharts of FIGS. 12, 13, and 6, the analysis data of MS1 and MS2 are both transmitted to the support system 2, and the support system 2 applies to the analysis data of MS1 and MS2. Make both decisions.

  That is, the terminal system 1 starts a series of processes in response to an inspection start command input from the input unit 16 to the arithmetic control unit 13. The arithmetic control unit 13 sends a command to the gas sampling unit 11 to sample a predetermined amount of inspection target gas (S61). The sampling gas is flowed into the mass analyzer 12, and the first stage (MS1) mass analysis is executed according to the procedure described in FIG. 4 (S62). The mass spectrometry data obtained by the analysis of MS1 is transmitted to the support system 2 together with the MS1 determination execution command by the control calculation unit 13 (S63).

  As shown in FIG. 13, when the support system 2 receives the MS1 determination execution command (S71), the support system 2 sends the mass spectrometry data to the explosives determination unit (I) 27 to execute the determination (S72). The explosives determination unit (I) 27 compares the input mass spectrometry data with the reference data I and determines whether there is a matching component (S73). The determination result is transmitted to the terminal system 1 via the arithmetic control unit 22 (S74). At this time, the arithmetic control unit 22 stores the determination result and the billing data in the database 24. The billing data is also transmitted to the terminal system 1.

  Returning to FIG. 12, the terminal system 1 receives the MS1 determination result (S64), and displays the result on the display unit 15 (S65). When the determination result of MS1 is “no explosive”, the arithmetic control unit 13 ends the process, and when the determination result is “explosive”, the mass analysis unit 12 performs the second-stage (MS2) analysis. A command to execute is sent (S66). In response to this, as in the embodiment of FIG. 1, the mass analyzer 12 performs an analysis of MS2 (S67). The mass spectrometry data of MS2 and its determination execution command are transmitted to the support system 2 via the communication unit 17 (S68).

  In response to this, as shown in FIG. 6, when the support system 2 confirms reception of the MS2 determination execution command in the arithmetic control unit 22 (S11), the support system 2 takes in the mass spectrometry data of the MS2 and loads the explosives determination unit (II ) 23 (S12). The explosive determination unit (II) 23 compares the input MS2 mass spectrometry data with the reference data II to determine the presence or absence of a matching component (S13). The determination result is sent to the communication unit 21 via the arithmetic control unit 22, and the determination result of MS2 is output to the communication line 3 (S14). At this time, if predetermined in the contract, the determination report of MS2 is registered together with the accounting data of the database 24 (S14). Depending on the contract, the billing data of the determination cost can be sent to the terminal system 1.

  Returning to FIG. 12, the calculation control unit 22 of the terminal system 1 receives the determination result of MS2 via the communication line 3 (S69), and causes the display unit 15 to display the determination result of MS2 (S70). With this series of processes, the explosives inspection process ends. When the determination result of MS2 is “there is an explosive”, the function of the treatment guide described in FIG. 7 operates.

  Therefore, according to the present embodiment, the same effects as those of the embodiment shown in FIG. 2 can be obtained, and both the reference data I and the reference data II relating to the explosives determination can be stored in the support system 2 owned by the service company. Therefore, there is an advantage that leakage of secret information such as know-how related to explosives determination (I) can be avoided.

  In the embodiment of FIG. 2 or FIG. 11 described above, when the determination result of MS1 is dangerous, an execution command of MS2 is output from the calculation control unit 13 or the calculation control unit 22 to the mass analysis unit 12. . When applied to the detection of explosives, the present invention is not limited to this, and the mass analysis unit 12 may be made to perform mass spectrometry of MS1 and MS2 continuously in advance. This is because in the case of explosives, the analysis conditions of MS2 can be specified without waiting for the mass analysis results of MS1. In this case, the calculation control unit 13 temporarily accumulates the mass analysis data I and II output continuously from the mass analysis unit 12, and explodes the mass analysis data II when the determination result of MS1 is dangerous. Output to the object judgment unit (II).

  FIG. 14 shows a conceptual diagram of another embodiment of the security system of the present invention. This embodiment is an example when applied to a suspicious object security system in a general place, and the terminal system 1 and the support system 2 are the same as the embodiments in FIGS. As shown in the figure, the terminal system 1 sucks the air around the handbag 9 through a suction pipe, and detects the presence or absence of dangerous goods. In such a case, since there are few places always equipped with an X-ray apparatus, it is assumed that a portable X-ray apparatus 10 is provided from a service company.

  In each of the above-described embodiments, the security system in which explosives are targeted for detection has been described. However, the present invention is not limited to this, and can be applied to a security service business that targets inspection and treatment of so-called dangerous goods. In addition to explosives, dangerous substances include substances that generally harm people and society, such as explosives, poisonous gases, and flammable substances. The presence / absence and type of these substances can be determined by detecting ion components specific to those substances by mass spectrometry, as in the case of the explosives described above.
