Fig. 1 illustrates an embodiment of vehicle according to the invention overload supervision system (100).System (100) includes carrying out the remote accessible server (102) of data communication with system database (104) and being positioned at multiple control stations (106) that road transport passage is along the line.Each control station has the unique identifier in system (100) and includes track-scale structure (108) and at least one electronic recognition mechanism (110).Electronic recognition mechanism (110) can know the vehicle (112) through control station (106) uniquely.In a preferred embodiment and as illustrated in fig. 1, meter heavy-duty machine structure (108) of each control station includes dynamically counting weight (WIM) scale (114) and static scale (116).
In addition, in a preferred embodiment, the electronic recognition mechanism (110) of each control station (106) includes any one in RF identification (RFID) reader, quickly response (QR) code reader, bar code reading device etc., and has any one that be fixed in the RFID tag of vehicle (112), QR code, bar code etc. through each vehicle (112) of control station (110).Electronic recognition mechanism (110) can uniquely identify each vehicle (112) through control station (110), and the weight measurement data to ensure each vehicle (112) can be associated with the correct vehicle (112) identified exactly.Preferably, the passive RFID tag of low cost will be fixed to each vehicle (112), and it will ensure the accurate identification of vehicle (112), is minimized by cost simultaneously.
In an alternative embodiment, electronic recognition mechanism (110) can include automatic number plate identification (" ANPR ") system, and it can identify vehicle (112) exactly based on the number plate of vehicle.
The preferred embodiment of system (100) can farther include the position detecting mechanism (not shown) being installed on each vehicle (112), and itself and server (102) carry out data communication.Position detecting mechanism can include any one in global positioning system (GPS), local positioning system (LPS), wireless location system (WPS) etc., and makes server (102) can determine the position of each vehicle (112) at any given time in real time.Server (102) thus allows for real-time tracking and determines that the vehicle (112) travelled along passage whether any point during it travels has stopped and/or having deviateed passage.
In addition, in a preferred embodiment, system (100) further provides for being fixed to electronic seal equipment (not shown) and/or the electronic gate sensor (not shown) of the cargo area (118) of the vehicle (112) travelled on passage.Should be appreciated that this water-tight equipment and/or door sensor will only be used for vehicle (112) generally, wherein the structure of vehicle (112) allows cargo area (118) locked and/or seals, and allows this kind equipment to be fixed on this.Water-tight equipment and/or door sensor and server (102) carry out data communication, and loading area can access data transmission to server (102) so that server (102) can detect distorting of cargo area (118) of vehicle (112).Alternately, door sensor can be configured to record opening in local memory module, closes and distort activity, it is preferable that comprise accurate date and timestamp information.Memory module also can be inquired when control station (106) at vehicle (112) by the Wireless Telecom Equipment being arranged near control station (106), and the data recorded can be checked by control station (106), to determine that whether goods is accessed along passage or distorts.
In use, server (102) is configured to receive the weight measurement data of each vehicle (112) through control station (106) and vehicle identification symbol from control station (106), the identifier of weight measurement data with correct vehicle identification symbol and control station is associated, and stores data on system database (104).In a preferred embodiment, during being travelled along passage by the vehicle (112) of meter weight and identification, server (102) can follow the tracks of the movement of vehicle (112) by means of the position detecting mechanism of vehicle (112), and detect any potential of the cargo area to vehicle (118) distort by means of the water-tight equipment of cargo area (118) and/or door sensor that are fixed to vehicle (112).
If be detected that vehicle (112) has carried out undesirable stopping, or deviate desired passage, or the cargo area (118) of water-tight equipment or door sensor instruction vehicle (112) is accessed or distorts, then server (102) is configured to determine that the weight of vehicle (112) counts, from it, the probability changed since weight for the last time at control station (106).If there is the weight of vehicle (112) to travel, at it, the probability changed during passage, then server (102) is configured to will be stored in the identifier mark of the vehicle (112) of system database (104) or is labeled as and has this implication.
It is to be understood that, communication between server (102) and control station (106) and position detecting system and electronic seal equipment and/or door sensor will all through mobile communications network (120) wireless generation, such as global system for mobile communications (GSM), Universal Mobile Telecommunications System (UMTS), satellite communication etc..Alternately, server (102) can communicate by means of wired connection with control station (106), such as telephone network, Networks of Fiber Communications etc..
Fig. 2 illustrates and monitors that system (100) is positioned at the use at one of passage control station along the line (200) place with reference to Fig. 1 overloaded vehicles described.Control station (200) includes WIM scale (202) and static scale (204) and the electronic vehicle identification mechanism (206) at or approximately at each scale (202,204).In preferred embodiment 2, control station (200) at least includes the first and second suspension rod gates (208,210), to be introduced by vehicle (212) and by control station (200).
In use, the vehicle (212) travelled along road transport passage is drawn towards WIM scale (202) in the first stage, and wherein vehicle (212) identifies by means of electronic vehicle identification mechanism (206) when crossing WIM scale (202) and counts weight.Vehicle is represented along the direction that passage travels by arrow (213).If the weight of vehicle (212) is defined as limiting lower than predetermined minimum load by WIM scale (202), then the first suspension rod gate (208) is opened, and consequently allows for vehicle (212) and is back to road (214) and continues to travel along passage.But, if the weight of vehicle (212) is defined as being higher than the restriction of predetermined minimum load by WIM scale (202), then the second suspension rod gate (210) is opened, and guides vehicle (212) into static scale (204).At static scale (204) place, it is identified then by meter weight that vehicle (212) is again by electronic recognition mechanism (206) alternatively.Should be appreciated that the weight measurement obtained at static scale (204) place is substantially more accurate than the weight measurement of WIM scale (202).Once vehicle (212) is counted weight exactly at static scale (204), it will be allowed to return to road (214) and continue to travel or the goods of vehicle (212) may have to be adjusted at passage, to ensure that the weight of vehicle (212) is allowing in load restriction.Should be appreciated that except utilizing suspension rod gate (208,210) to guide beyond vehicle (212) in control station (200), guide signing can be used, it is preferable that electronic guide indicates.
It should be noted that, the process that previous paragraph describes is the process followed along the first control station (200) place that passage runs at vehicle (212).If previously static scale (204) meter at control station (200) place is heavy in scheduled time frame for vehicle (212), and vehicle identification accords with not serviced device labelling, then vehicle (212) can enter static scale (204), even if WIM scale (202) instruction vehicle (212) is likely to overload.Once WIM scale (202) instruction vehicle (212) is likely to overload, it is determined that vehicle (212) heavily will be described in greater detail below the need of at static scale (204) place meter.
Moreover, it will be appreciated that also contemplate for the factor added, such as type of vehicle, load and vehicle load type etc. determining when whether vehicle is permitted to return to road or vehicle whether should adopt static scale meter weight.
In a preferred embodiment and as Fig. 2 illustrate, each control station (200) includes auxiliary electron identification mechanism (216), so as to do not count at control station (200) place weight vehicle (212) be identified.Auxiliary electron identification mechanism (216) can be additionally used in identification be classified and/or directed will static scale (204) place meter weight but also do not count weight vehicle (212).It will by guide signing but not the situation that is directed in control station (200) by suspension rod gate be especially relevant with vehicle (212).It is along the line that auxiliary electron identification mechanism (216) typically lies in road (214), and by vehicle identification symbol transmission to server, can not weighed to be stored on system database by server and vehicle identification symbol is labeled as instruction vehicle (212).When vehicle identification symbol is marked as not yet meter weight, this vehicle (212) can be informed to the control station (200) farther along passage, and this control station (200) can warn and/or sanction the vehicle (212) through this control station (200), alternately, vehicle (212) owner directly will be sanctioned owing to not complying with rule and/or regulation.It is to be understood that, if the vehicle (212) through control station (200) cannot be identified, then because vehicle (212) does not have the RFID tag etc. being fixed thereon, therefore vehicle (212) not identified for the control station (200) that can notify along passage is travelled on passage by server, and this control station (200) can suspend and/or warn vehicle (212).Auxiliary electron identification mechanism (216) also equipped with automatic number plate identification (ANPR) system, can enable the server to the number plate that the vehicle (212) of weight do not counted in record through control station (200).
It is stored on system database owing to according with through the weight measurement data of each vehicle (212) of control station (200) and vehicle identification, therefore data can be efficiently used by other control stations (200) along passage more distant positions, as being hereafter about to describe.It is evident that, the substantial advantage of this system is in that, once the weight of vehicle is accurately measured on the static scale (204) of one of control station (200) and is concurrently now in legal restriction and is recorded in system database, then the WIM scale limited close to predetermined minimum load at subsequent control station place is measured slightly higher or lower slightlyly, can still allow for doubt vehicle and again count weight through control station (200) without at static scale.This can be substantially reduced the meter weight number of times that given vehicle (212) is subjected to along passage, and car operation person and control station bring the cost of essence and time save.
Fig. 3 illustrates the flow chart of the method for the road transport path monitoring vehicle load along the system used illustrated in Fig. 1 and Fig. 2.In first stage (300), remote accessible server (102) receives vehicle identification symbol and weight measurement data from being positioned at road transport passage control station along the line (106).Weight measurement can be obtained by the WIM of control station or static scale and make labelling.
If vehicle (112) previously and identifies not by meter weight at control station (106), then in next stage (302), weight measurement data are associated by server (102) with vehicle identification symbol and control station identifier, and associated data are stored in system database (104).
Alternately, if vehicle (112) is previously heavy by meter at the control station (106) along passage, then in next stage (304), server (102) identifies vehicle (112) the information that retrieval associates from system database (104) with vehicle identification symbol.This information is forwarded to the control station of vehicle (112) process.The weight measurement data of previous receipt will be included with the vehicle identification information that associates of symbol and receive from it the identifier of control station (106) of these weight measurement data.
Remain in this control station place, in next stage (306), server (102) determine vehicle (112) whether in the scheduled time frame control station (106) place previously counted weight or vehicle identification symbol is labeled, thereby indicate that the last meter from vehicle (112) restarts the probability that the weight of vehicle (112) changes.As above-mentioned, if vehicle (112) presents some characteristic or behavior, appointment time period or deviation passage or electronic seal equipment and/or door sensor instruction are such as suspended it may happen that the distorting of cargo area (118) of vehicle (112), then vehicle identification symbol will typically be labeled, and thereby indicate that the weight of vehicle (112) is likely to during travelling along passage and there occurs change.
If vehicle (112) if not accorded with not labeled by meter weight or vehicle identification in scheduled time frame, then in next stage (308), the control station (106) communicated is kept to determine whether weight measurement data can allow in parameter or restriction predetermined with server (102), for instance limit lower than maximum load.First weight of vehicle (112) completes typically with WIM scale (114).If weight measurement data are in predetermined allowed parameter, then in next stage (310), vehicle (112) is allowed to continue to travel at passage.
On the other hand, if weight measurement data are not in predetermined allowed parameter, then in next stage (312), when vehicle (112) is by meter weight, the control station (106) at place determines that vehicle (112) is likely to overload.Vehicle (112) will be drawn towards static scale (116), to accurately determine the weight of vehicle (112).
In stage (306), if in scheduled time frame, by meter weight, vehicle identification symbol is not labeled vehicle (112), then in next stage (314), keep the control station (106) that communicates to determine whether the weight measurement from current WIM scale is in predefined parameter with server (102).
If weight measurement data are in predefined parameter, then in next stage (316), vehicle (112) is allowed to continue to travel on passage.
Alternately, if weight measurement data are not in predefined parameter, then in next stage (318), keep with server (102) control station (106) of communication to compare the weight measurement data received from WIM scale and limit and catch one or more previous control stations (106) and be stored in the weight measurement data associated with vehicle identification symbol system database (104) with the weight of permission.If such a comparison indicate that WIM scale measurement exceedes predetermined restriction, then in next stage (320), control station (106) determine that vehicle (112) is likely to overload.Vehicle (112) then will be drawn towards static scale (116) again, to carry out weight more accurately.If this more also indicates previous control station (106) place that same vehicle (112) is found on passage to exceed restriction, and it is still above restriction, then vehicle (112) will be directed to static scale (116), additionally, transmit, to server (102), the notice that the specified control program at previous control station (106) place is likely to do not applied suitably.
On the other hand, if such a comparison indicate that the previous weight measurement data received from server (102), the vehicle weight change that more particularly occurs by means of the weight measurement data of static scale (116) previously meter weight are in and can allow restriction, if and vehicle identification symbol is not labeled, then in next stage (322), vehicle (112) will be allowed to continue to travel along passage.
Should be appreciated that system (100) can compare above-mentioned various weight measurement by the control station along passage being interconnected and made its shared vehicle identification symbol and weight measurement data.The comparison of weight measurement loads making system (100) to determine more accurately especially to the vehicle (112) close to maximum allowable load actually the need of adopting static scale (116) again to count weight, and wherein WIM scale (114) indicates vehicle (112) close to its maximum admissible load.Therefore this system will reduce when vehicle (112) has been loaded to close to maximum admissible load, vehicle (112) will need the quantity of static scale (116) the meter weight of experience, thus substantially reduces unnecessary static scale (116) meter weight involved time and cost waste.
It is to be understood that further, the use of position detecting system and electronic seal equipment and/or door sensor will make system (100) can effectively monitor the behavior of the vehicle (112) in travelling along passage, and whether the weight of vehicle (112) is altered after its for the last time meter weight thus to make system (100) can determine.Therefore, if vehicle (112) is loaded to close to maximum allowable restriction, and static scale (116) meter heavily indicates vehicle (112) to be in maximum to allow in restriction, then system (100) will can determine whether vehicle (112) presents and may indicate that its weight is counted from for the last time and restart the behavior changed.If vehicle (112) presents the behavior, and the reading of WIM scale (114) again indicates that the weight of vehicle (112) is in outside predetermined allowed parameter, then system (100) guides vehicle (112) into static scale (116), to carry out weight more accurately.This not only will significantly improve the efficiency of control station (106), and what realize vehicle (112) effectively transships supervision simultaneously, and reduce vehicle (112) and travelling static scale (116) the meter tuple amount being possible need experience along passage.
