Technical field
The present invention relates to utilize the method and system of state of the internal environment of multiple sensors for monitoring container.Especially, but be not limited to, utilize multi-sensor surveillance to run through the method and system of state of the internal environment of the combined transportation cargo container in the supply chain.
Background technology
Most shipping of goods all over the world are all by being called the thing shipping of combined transportation cargo container.Used here term " container " comprises any to the opaque container of radio frequency signals (no matter whether having added wheel), including, but not limited to the combined transportation cargo container.Prevailing combined transportation cargo container is considered to the dry intermodal container of International Organization for Standardization, the meaning be they meet special size, machinery and other standard by ISO issue, the development of the long-distance transport equipment of the container by encouraging compatibility standard, treatment facility, foreign-going ship, railway equipment and all modes that are used for the transmission of goods water route all over the world and make and be used for promoting global trade.Have at present more than 1,200 ten thousand such containers and many more professional containers, the frozen products insulated container that for example carries perishable commodity circulates in the whole world.Annual about 6,000,000 containers of having freighted, 17000 of similar every days, half of the total value of approaching annual all goods that receive of receiving separately of the U.S..
Because nearly 90% all transmitting in container of all goods of shipping in the world, encased conveying has become the spine of world economy.
It is unpractical that the absolute magnitude of the container of whole world transportation will be implemented actual inspection one by one, in fact enter only have in the container of the U.S. 2% to 3% by actual inspection.The risk that terrorist's biology, radiation or volatile equipment is introduced by cargo container is very high, considers the importance of container in world commerce, and the consequence that such incident causes international economy may be catastrophic.
Even sufficient resources is put in the actual inspection work of implementing all containers and goes, such task still can cause serious economic consequences.
For example only the time of delay just can cause closure of a factory and the delay of unnecessary and high cost in the process that conveys goods to client.
Present container designs fails to provide suitable mechanism to set up and the security of monitoring container or their content.Typical container comprises one or more hasp mechanism, and the indication " strip of paper used for sealing " of its permission insertion plastics or metal or the tradition " strip of paper used for sealing " of bolt fence are protected the door of container.The door hasp mechanism that tradition is used is easy to destroyed, for example, and by on the attachment bolt that is installed on hasp outdoors, holing.By the replacement of using common cutting tool and very simply duplicating strip of paper used for sealing, the traditional strip of paper used for sealing that uses also is easy to destroyed at present.
The more senior solution that proposes is e-seals (" e-seal ") recently.Though these e-seal are equivalent to traditional door envelope and by unstable identical hasp mechanism, as the accessory application of container in container, but these e-seal also comprise the electronic equipment that can transmit the e-seal sequence number such as radio or radio reflections equipment etc., and the signal that is cut or damages after the e-seal installation.Yet described e-seal can not communicate by letter with the inside or the content of container, can not will be referred to the inside of container or the information of content and be sent to miscellaneous equipment.
Described e-seal typically adopts low power radio transceivers or utilizes the radio frequency backscatter technique, information from the e-seal tag transmits on the card reader that is installed on the end-gate for example.The radio frequency backscattering relates to relatively costly arrowband high power radiotelegraphy and the radio broadcasting technology based on unit radar.The radio backscatter technique need card reader transmission have the higher transmit acc power (just, radio signal 0.5-3W), the signal with modulated or coded data from e-seal be reflected or backward scattering get back to card reader.
In addition, that the application of current e-seal is used is wide-open, unencrypted and unsafe air interface and agreement, allows relatively easy plagiarization and the forgery of e-seal.Present e-seal also only works on the frequency bandwidth of this locality mandate that is lower than 1GHz, owing to its radio regulation(s) in present many countries does not in the world allow their use, makes to be difficult in when global trade relates to intermodal container and realizes.
In addition, it is invalid that e-seal comes the security aspect of monitoring container from the angle of the replaceable form of invasion or the angle that relates to container contents, because container can pass through the destroyed or harm of various methodologies, and the method for tradition visit internal container only is the door by container.For example, biopreparate can be inserted in the container by the standard air vents of container, or the sidewall of container can be pierced path is provided.Although traditional strip of paper used for sealing and e-seal provide a kind of form of door of security monitoring container, the both can be damaged.Traditional strip of paper used for sealing and e-seal mostly just are suspended on the door hasp of container, and when container was handled for example steamer loading and unloading, they all were exposed under the physical hazard.In addition, the content that traditional strip of paper used for sealing and e-seal can not monitoring containers.
Utilize multisensor to come the inner thing of monitoring container to cover multiple possible problem and/or prestige danger state is necessary.For example, container can be used to material ship dangerous, radiation, such as bomb.In such scheme, in order to detect the existence of serious like this prestige danger, wireless senser will need.Unfortunately, the terrorist menaces single kind that is not limited to threaten.Chemistry and biological weapons both are used in a large number and the public are produced serious threat.Therefore, two types detecting device may all need, and particular case, radiation, gas and biology sensor can be considered to suitable.A problem of the use of this sensor is that when sensor placed the inside of container, how on earth the data of this detection were transferred to the external world.Because the intermodal container of standard is to adopt for the opaque steel of radio signal to make, in fact can not has a reliable system unless data transmission is addressed and be used for from placing the sensor transmissions data of such container fully.If data can be transmitted effectively from the sensor that is deployed in fully the intermodal container, for example the state and/or the security parameter of temperature, light, inflammable gas, protein (biometric sensor) motion, radio activity, biology and other state can be monitored.In addition, the integrality of the installation of such sensor is crucial and need protects the more ripe surveillance of door hasp mechanism of container door than the tradition " strip of paper used for sealing " that the indication " strip of paper used for sealing " of plastics or metal or bolt fence are inserted in the above-mentioned permission of mentioning.
Except that above-mentioned, the supervision of the integrality of container may relative complex by the door motion.Although very heavy load is reasonably constructed and carried to container structure, comprise single container and rely on container stacked mutually, each container also is designed to regulate horizontal load and regulates the intrinsic dynamic stress of (especially) ocean transmission and mobile, and this stress usually runs into moving in the shipping of container.The iso standard that is used for typical container at present can allow because lateral load mostly is 40 millimeters most with respect to the motion on the Z-axis of other container.Therefore, the safety method based on the close relation that keeps the physical interface between two container doors generally is unpractiaca.
Therefore, provide a kind of cost, permanent feasible and reliable mode to come the monitoring container door to have superiority with respect to the method and system of the motion of container structure with economy.Equally, provide a kind of data routing or gateway, it is used to be placed in the container, and a plurality of sensors detect the alternative or the dangerous existence or the illegal contents thing of invasion and are sent to outside receiver.

Embodiment
Have been found that the container security device of this type of following elaboration, demonstration and description, can be positioned in the container and be reliably, to be used for effective detection its integrality, state and content to container.Will describe in detail as following, equipment is positioned in the predetermined structure division of container in accordance with the principles of the present invention, to be used to show minimum structural moving.Described move results from this container owing to conventionally load, handle and by the extension along interface between traditional container framework and the door.Elastic washer is usually placed and is extended by interface area around described door, with guarantee this container be waterproof and also the weatherproof of protection commodity.This equipment is suitable for: (a) simply do not have instrument and install; (b) the intermittent signal transmission of self-powered; (c) sensing is with respect to the pressure of flexible door seal, is used to indicate the deviation that moves of container door with transmission, comprising invasion.
Figure 1A illustrates the chart of the communication between the system element in accordance with the principles of the present invention.This system comprises equipment 12, at least a card reader 16, server 15 and software backbone 17.Equipment 12 guarantees that this container is not destroyed after container 10 is protected.Container 10 is by card reader 16 protections and tracking.Each card reader 16 can comprise and be used for the hardware or the software of communicating by letter with server 15, for example be used for the modulator-demodular unit by transmission data such as GSM, CDMA or be used for the cable of data download to PC, this PC by transmitted data on network to server 15.Variously be used for from card reader 16 to server that 15 apparatus for transmitting data can be applied to card reader 16 or become an independent equipment.This card reader 16 can be configured to a handheld reader 16 (A), mobile card reader 16 (B) or fixed reader 16 (C).Handheld reader 16 (A) is combined with mobile telephone, personal digital assistant or portable computer for example.Mobile card reader 16 (B) is a fixed reader that has the GPS interface basically, typically uses in mobile device (for example use existing GPS, AIS or similarly truck, train or the steamer of positioning system) to protect, follow the tracks of in the mode that is similar to handheld reader 16 (A) and the integrality of definite container.In stationary installation, for example at the harbour or the shipping harbour, fixed reader 16 (C) typically is installed on crane or the door.This card reader 16 is mainly as the relay station service between equipment 12 and the server 15.The record of server 15 storage security item details, for example door incident (for example security destruction, container security inspection, protection container and unload containers), position and any additional peripheral sensor information of wanting (for example temperature, mobile, radiation).This server 15 is accessible in conjunction with software backbone 17 to authorized user, so as to determine container 10 Last Known Location, the container of any amount is made the integrality inquiry or is carried out other bookkeeping.
With reference now to Figure 1B,, shows from the flow process 2 of a typical supply chain of node (A) to (I).Reference mode (A) at first, container 10 waits the goods of having packed into by consignor.At node (B), load good container and transport to the harbour by highway or transportation by railroad.At node (C), this container enter the GATT at loading harbour (gate in) such as the shipping harbour.
At node (D), container loading is to the steamer by forwarding agent's operation.At node (E), container betransported the harbour that the merchant is transported to unloading.At node (F), container trailing wheel discharge afloat.After node (F) unloading, node (G) container by the truck of freighting on and go out to close (gateout) from the harbour of unloading.At node (H), container is to arrive the expectation place with the similar mode of this node (B) by land transport.At node (I), on the basis that arrives the expectation place, container is unloaded by the consignee.
It is evident that for those skilled in the art, lack detection visible or that other is traditional, having many times at the intranodal of flow process 2, the security of container may be endangered.In addition, the state of the content of container all is unknown fully for relating in the flow process 2 anyone, up to node (H) when the content of container unloaded.
Fig. 2 A is the block diagram of equipment 12.Described equipment 12 comprises antenna 20, RF/ Base Band Unit 21, microprocessor (MCU) 22, storer 24 and door sensor 29.This equipment 12 can also comprise interface 28, is used for the various internal states of the connection of additional sensor with monitoring container, and for example temperature, vibration, radiation, poison gas detect and moves.This equipment 12 can also comprise optional power supply 26 (for example battery); Yet other detachable and remote power supply also can be used by equipment 12.When power supply 26 comprises battery (as shown in the figure), the inclusion of the power supply 26 in equipment 12 can help extending battery life, can allow power supply 26 be in less temperature fluctuation because power supply is in the inside of container 10.Power supply is present in damage or the damage capability that helps in the container reducing to power supply 26.This equipment 12 also optionally comprises and being used for directly and the connector of card reader 16 interfaces.For example, connector can be positioned at the outer wall of container 10, is used for the visit of card reader 16.This card reader 16 can be connected to the information that slave unit 12 is downloaded by cable or other direct interface then.
Microprocessor 22 (being equipped with internal storage) comprises from door sensor 29 recognitiion gate incidents, for example, and container security request, container unload request and container security inspection.The door incident that is identified comprises that also the security of the content that may endanger container 10 destroys, such as open door again after container 10 cuts out.This incident can be stabbed and be stored in and is used to be transferred to card reader 16 in the storer 24 joining day.This incident can be immediately or cyclical transmission, or response is transmitted from the inquiry of card reader 16.Here the door sensor of Xian Shiing belongs to pressure sensor types, but it also can be, for example, and interchangeable feeler, proximity transducer or detect the sensor of any other adequate types of the relative motion on two surfaces.The term of the pressure transducer of using here is including, but not limited to these other sensor types.
Especially, according to the present invention, equipment 12 utilizes " sleep " pattern to reach the economic utilization of power supply 26.In sleep pattern, the circuit part of equipment 12 is closed.For example, remove sensor 29 and be used to measure cycle length of one's sleep t
SleepTime measuring unit (for example counter in the microprocessor 22) outside all circuit all close.In a typical embodiment, detect a door incident when having passed through the cycle length of one's sleep or having worked as door sensor, the stick holding circuit power supply of equipment 12.
When the signal that equipment 12 receives from card reader 16, this equipment 12 keeps activating so that communicate by letter with card reader 16 under requested situation.If equipment 12 does not have to receive the request from card reader 16, this equipment 12 will only guarantee be referred to as wireless signal time cycle or breathing (sniff) " cycle " (" t at needs
Sniff") time cycle in do not have signal to deposit under the situation to keep activating.
At t
SniffDuring arrival, equipment 12 cuts off the power supply once more, unless time measuring unit and door sensor 29, activated equipment 12 once more after a door incident taking place or experienced another cycle length of one's sleep.
In a typical embodiment, the card reader signal time cycle is significantly shorter than (for example on some orders of magnitude less than) cycle length of one's sleep, so that the life-span of equipment obtains prolonging (for example on some orders of magnitude) with respect to " continuing to start " scheme accordingly.
The cycle length of one's sleep and card reader time cycle (cycling time) sum obtain a temporal lower bound, and equipment 12 and card reader 16 must arrive this restriction and know existing of equipment 12 to guarantee card reader 16.The related time cycle will be called as elapsed time (" t
Pass").
Yet elapsed time (" t
Pass") controlled by particular case.This elapsed time in some cases can be very long (for example the equipment on freight container 12 communicating by letter with the card reader 16 on truck front portion of transporting container 10 or chassis several hours), or in other cases can be very short (for example when the equipment on container 10 12 at a high speed through several seconds zero point of fixed reader 16 (C)).Typically for all application, each equipment 12 will be in its life-span, and some situation has the bigger elapsed time and some situation has the less elapsed time.
Therefore the described cycle length of one's sleep is selected usually like this, this cycle length of one's sleep and the shortest possibility consistent (" t of elapsed time
Pass, min").That is relational expression,
T
sleep≤t
pass，min-t
sniff
Can realize according to the various modes of operation of equipment.The cycle length of one's sleep is distributed to equipment (for example, in life cycle) with the dynamical fashion of the particular case that depends on equipment.
When card reader 16 was communicated by letter with equipment 12, this card reader 16 was come reprogramming, the cycle length of one's sleep of change equipment 12 according to the position and the function of card reader 16 from data or other retrievable information in card reader 16 of equipment 12.For example, be loaded into surely on truck or other the suitable vehicles by crane or trailer if the container 10 of equipment 12 is housed, these suitable vehicles are equipped with card reader 16, and truck and trailer do not assemble any card reader 16.The expectation truck travels through being positioned at the fixed reader 16 (C) of harbour outlet or container discharge point with high relatively speed.Therefore, the card reader on the vehicles 16 (C) needs programming device 12 to be the short cycle length of one's sleep (for example～0.5 second).
A branch of above-described overall thought can be, according to circumstances, card reader 16 can program sequences of sleep periods in equipment 12.For example, when container 10 is loaded on the steamer, when travelling, per hour wake up once just enough at sea for equipment 12.Yet,, may just require short sleep cycle can connect with equipment 12 with the card reader 16 on the crane that guarantees unload containers 10 in case estimate will be near the purpose harbour for steamer.Card reader 16 on the crane that is used for loading container 10 on the steamer is programming device 12 like this: at first, per hour woke up once, woke up once in per then 10 seconds in lasting 3 days.
In another scheme, card reader 16 moves on to equipment 12 and can revise the cycle length of one's sleep according to physical location.For example, can hypothesis set equipment 12 in the vanning 10 can be with the card reader 16 of the truck that is used for drawing container 10 mutual continual communication of the process of drawing container.As long as far away enough from the destination of container 10, card reader 16 can be slept in the time interval (for example one hour) that prolongs by programming device 12.When card reader 16 was equipped with GPS (GPS) receiver or other positioning equipment, this card reader just can determine when this container 10 is near its destination.In case container is near its destination, card reader 16 can be waken up by programming device 12 more frequent (for example per seconds).
Above-described method for managing power supply is explained with reference to the equipment 12 in the traffic condition of the freight container by means of transportation such as sea-freight, highway, railway or aviations or other goods, those skilled in that art are appreciated that method for managing power supply described above, also can be applied to for example animal transport, highway toll machine motor vehicle identification and antitheft, and stock management and supply chain management.
With reference now to Fig. 2 B,, shows first skeleton view of equipment 12.This equipment 12 comprises: the sway brace 102 that comprises the shell 25 of data cell 100 (not shown), extends from shell, and an angular relationship is arranged from the outward extending antenna arm 104 of sway brace.As described below, the length of the size of shell 25, sway brace 102 and the configuration of antenna arm 104 are carefully chosen out and the universal container compatibility.Shell 25, sway brace 102 and antenna arm 104 typically are moulded in polyurethane material 23 or the analog to protect it not affected by environment.
Still with reference to figure 2B, the part of the material 23 of sway brace 102 is cut at least one magnet 27 wherein to be shown and the layout of at least one door sensor 29 on it.Magnet 27 allows the stability of the enhancing of equipment 12 in the following container that will describe, and door sensor 29 detections simultaneously are along the variation of the pressure of the packing washer of the following container that will describe.
