Description

TRAFFIC MONITORING SYSTEM FOR VEHICLES DESCRIPTION OF THE INVENTION The invention relates to a traffic monitoring system for vehicles of the type comprising a towing unit and one or more towed or transported units, the towing unit comprising: a towing unit. data processing that has accessories to transmit and receive adapted to read / write messages of stationary marks, or to read / write by means of a wireless transmission. Such a traffic monitoring system is known from patent application DK No. 1095/94. This system is extremely useful in relation to the supervision of vehicles, for example, for the identification of vehicles and the determination of their positions. In relation to two-part vehicles, for example, a truck consisting of a motor vehicle and a attached trailer, it is not very expedient that all data accessories are present only in the towing unit, that is, in the vehicle motorized. This means that the communication between the trailer and the transport units or transported units is interrupted by the uncoupling of the towing unit.

Where a truck and a motor vehicle, even if the motor vehicle has a data processing accessory, are left parked, the truck is extremely vulnerable to being stolen or damaged. In this regard, it is clear that if the vehicle is a refrigerator vehicle with meat or other expensive items, it is of great importance that they can be lost. Accordingly, the object of the invention is to improve the existing known system of the DK patent application mentioned above, in such a way that the same safe monitoring and determination of the position of a transport unit or unit transported, the which, for example, is left in a parking lot, is achieved. This object is achieved according to the invention, in which the towed unit or conveyor or units have another data processing unit with transmission and reception accessories capable of exchanging information with the data processing unit in the towing unit by means of of a wireless transmission or through an interface. Hereby it is ensured that the unit towed or transported, whether it is connected to a towing unit or left in a parking lot, is securely protected against theft and other damage, since the data processing accessories in the unit towed will respond instantly to abnormal events and notify the data processing unit in the towing unit, which can notify the police and the like. It is convenient according to the invention, as set forth in claim 2, that the data processing unit of the unit or units towed or transported can exchange information with the local data processing units, which are located stationary outside of the towing unit. Hereby, an established system in which the unit towed or transported, when left alone in a terminal, is observed as surely as if it were coupled to a towing unit. Furthermore, it is convenient, as set forth in claim 3, that the unit or units towed or transported have a first antenna capable of reading the information of a mark, which is placed on the unit or units transported. The transported unit and the unit it transports hereby will be very closely linked to each other, in the sense that when the aerial antenna tries to read the mark, it will be detected instantaneously, if the mark is no longer present, for example, if You have tried to remove the transported unit. In this case, the data processing unit in the transported unit immediately establishes that it is not in the location where it should be, which can be carried out in that it immediately sends signals to a local data processing unit, which can immediately pass the signals to the police or similar. When, as set forth in claim 4, the transported unit or units have a mark capable of receiving or transmitting instructions or information from the data processing unit by means of another antenna, which is also located in the transported unit, the transported unit can advantageously provide information of its position. The information and instructions can also be read by a portable device. Similarly, the data processing accessories in the towed unit can be written to, and read from, the same brand by means of an antenna in the transport unit. This opens the possibility of protection against the loss of related data for example, with the related transport course. It is also convenient that the unit or units transported have another mark located on the upper side of the unit or units towed. This is particularly advantageous, if one imagines that the transported units are formed by stackable containers. In each case, each individual container can be easily identified and placed, since the first container placed directly on a laying base or terminal is placed by reading the buried marks on the surface covering the base, or the terminal and when the next container is stacked, the next container can read the identity of the lower container, whereby the position is unambiguously determined. If you try to remove any of the containers, the container that is removed can not read the identification in the container below it and the data processing accessories on the container which has been removed, therefore will immediately give the alarm. The same placement principle can be placed on shipments equipped with data processing accessories and markings on surfaces on the platforms. As set forth in claim 6, the data processing unit of the towing unit and the stationary data processing units, the GSM or GSP system can communicate with the satellite. This provides a very certain position determination no matter where the towing unit is present and opens the possibility, by means of one of these systems, of asking for the status and position of the unit or units transported or by remote activation of the unit. the accessories in the individual transported unit.The detectors, such as vibration detectors and temperature detectors, may also be connected to the data processing units of the unit or units transported. This improves the certainty that any undesirable removal of the transported unit will be detected, since a vibration detector immediately sends signals to the data processing accessories of the transport unit and gives the alarm in the same manner as above. Similarly, temperature sensors located in combination with the data processing accessories in the transport unit can give an alarm in case of inconvenient temperature changes and, by means of communication with the data processing accessories in the towing unit or in the terminal, inform the carrier or owner of the freight of the present condition in the transported unit. In general, advantageous embodiments of the invention are defined in the dependent claims.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained more fully in the following with reference to the drawing, which shows the preferred embodiment of the invention, and in which figure 1 shows a truck consisting of a motorized vehicle and a truck, which transports a container with associated data processing accessories, Fig. 2 is a block diagram of the data processing accessories in the motorized vehicle and a transported container, and Fig. 3 shows the invention applied in relation to, for example a train and connected to a satellite, GPS and GSM system. Figure 1 shows a transport unit, here shown as a unit consisting of a motor vehicle and a truck transporting a container. In other words, a transport unit, which is of a type that has a towing unit and a towed or transport unit loaded with a transported unit (container). Of course, any other transported unit can be contemplated, for example, a train that has a locomotive and several wagons or a ship. In the motor vehicle, 1 designates the data processing accessories, which communicate with a satellite, a GSM system and a GPS system, respectively, by means of the antennas 2, 3, 4. In addition, the lower part of the The motor vehicle is provided with an antenna 6 capable of reading a 10B mark, which may be located on a road, a parking lot or even on a ship. In this specification brand means a microchip that has an antenna, accessories that transmit and receive, a memory as well as a source of passive inducing energy (ie, its own power supply). 7 designates a radio link to a data processing unit 15 located in the transported unit. The data processing unit 15 essentially corresponds to the data processing 1, but with the difference that it does not have independent communications accessories for the satellite, GSM or GPS system. In addition, as shown in FIG. 1, the lower part of the transported unit is provided with an antenna 16, capable of communicating with a mark 10D, which is located on the transport platform. In addition, a transmission antenna 11 is provided for the data processing unit 15 capable of transmitting information to and reading information from a mark 10C located in the transported unit. As will be seen, the transport platform 17B is further provided with an antenna 12 having an interface 8 for the data processing system 1 in the towing unit 17A, allowing the towing unit to read from, and write to the marking mentioned. Finally, several detectors, such as a temperature detector 14 or a vibration detector 13 are associated with the data processing unit. The interface 8 can be used in place of the wireless link 7 for communications between the motor vehicle and the transport unit or the transported unit. The data processing system 15 shown in Figure 1 can be located on all types of towed platforms with permanent structures, or in interchangeable / flexible containers and platforms. By means of the antenna 16, the data processing system can read the information of the mark 10D located on the transport unit 17B, or of the mark 10B located on a road or on a surface coated on a ship, terminal or parking lot . If a withdrawn transport unit, or a transport unit and a transported unit are separated, such withdrawal will be recorded by the data processing system and an alarm procedure will be implemented. By means of the antennas 11 and 12, located in the transported unit and the transport unit, both of the data processing system 1 and the data processing system 15, can be read from, and written to the mark 10C, located in the transported unit. The 10C mark may contain information for the identification of the transported unit, as well as data and information related to the related transportation course. Accordingly, the 10C mark can be used as a backup function for the total amount of information related to the related transport, regardless of whether the information and data are collected or generated in the data processing system 1/15 in one trailer unit 17A, a transport unit with a firm superstructure 17B or a transported unit 18. The information in the mark 10C can also be read using a portable device. Where the transport unit 17B or the transported unit 18 is left in a terminal or park disconnected from the data processing system 1 in the towing unit 17A, any attempt to remove the truck will be recorded by the vibration detector 13, which it instantly notifies the data processing system 15, which can alert the data processing unit, located stationary, closer by means of its transmission / reception accessories. If one imagines that the transport unit 17B or the transported unit 18 is stackable, the first and lowest unit in a stack can read the label 10B, located on a surface on a ship, a terminal or a coating on a traffic path , by means of the antenna 16 in the lower part of the unit, and passing the information read and its own data by means of the transmission / reception accessories to the data processing systems located stationary 42/44. The next unit in the stack can read the label 10A, located at the top on the underlying unit, by means of a corresponding antenna, and likewise passes over the information read and the data itself through the transmission / reception accessories to the data processing unit, located stationary, which is hereby, enabled to place the transport unit or individual transported unit in the individual cell 43. Figure 2 is a block diagram view of the processing unit of data in the towing unit and the towed or transported unit, respectively. As will be noted, the data processing accessories in the towing unit comprise interface couplings for the satellite, GSM and GPS system and have a wireless link 22 to be used when communicating with the data processing unit 15 in the towed unit or transported. In addition, 24 designates a reading and writing unit of the RFID type (Radio Frequency Identification Detection System) which, by means of the antenna 6 in the towing unit, can read information from, or write information to, a brand. 10B located on a road or surface. The data processing system 15 in the transported unit has no direct connection to the satellite, GSP and GSM systems, but can communicate via a wireless interface 22 with the data processing system in the towing unit as well as with stationary data processing systems of the same type as that used in the towing unit. further, the data processing unit has connected the detectors, such as vibration detectors 28 and temperature sensors 29, as well as a power supply in the form of a battery 18. In addition, it will be noted from the figure that More equipment can be connected, as needed. Figure 3 shows schematically how the system works in relation to a satellite, GPS system and GSM, the figure shows a train 34, which has a locomotive 35 and wagons 36. In relation to such a train, in which each wagon 36 has a data processing unit corresponding to the data processing unit 15, mentioned in the above, it is advantageous that the communications between the locomotive 35 and the wagons 36 are wireless as shown in 37. In addition, the communication between the unit 35 and the towed or transported units 36 can be carried out by means of fixed connections 38. It is also shown that the locomotive 35 can communicate via the GSM system 39 or be connected in addition to the communications carrying the existing satellite or systems 45. Correspondingly, the road transport unit 40 is shown, in which the communication between the trailer and the towed units or transported, it is also carried out by means of a wireless connection 37 or by means of a fixed connection 38 between the data processing systems of the two units, and communication with the outside world can be carried out by means of the GSM system 39 or satellite-based communications and communication systems 45. In addition, the figure shows a stationary data processing unit 42, which can be placed in a terminal, parking lot or other location where communication with units 41/43 does not transported, it will be established. In addition, for communication with the towing units, the stationary data processing system 42 can communicate with the outside world, both by means of GSM 39 and the satellite-based communication systems 45. The communication between the stationary data processing 42 and the units 41/43 that are not in the transport, are wireless 37, but can also be carried out by means of the fixed connection 38. Figure 3 further shows how a transport unit 41 or a unit of transport stacked 43, can communicate by means of antenna 16 with the mark 10B located on a coated surface, and thus contributes among other things to determine the position. Figure 3 further shows in schematic form that the stackable transport units 43 have marks 10A and the antennas 16 in the upper part and the lower part, respectively and therefore, can read the underlying unit and thus contribute to the placement of the individual stacked unit. Finally, Figure 3 shows schematically how the same accessories in the transported units can be used, where a stationary data processing system is installed in a shipment 46. In addition to the possibility of placing the individual transport unit 43, the communication between The individual transport unit and the outside world can be established by satellite or radio by means of ordinary communications and accessories for the placement of the shipment. Although the invention has been described in connection with towing and towing units, transport and transported on land, it is within the scope of the invention to use the technique and method described in the above in closely related connections. In this way, the same invention can be conceivably used to observe containers or containers in air traffic.
