  • a methyl alcohol fuel cells based generator is firmly attached to the trailer.
  • Adjustment means, a control unit, modems and material for electrical installations are kept in a hollow box with a lock and a lid which can be opened in the upward direction.
  • a preferred embodiment comprises such a telescopic extensible mast 2 which is similar to the mast currently used in a great extent in most fire-fighting units.
  • This telescopic mast 2 is pneumatically extensible and it reaches a height of seven meters (necessary to obtain exact data from the traffic or from the cameras). This height will be even slightly higher, as the telescopic mast 2 comprises a remotely controlled robotic head.
  • the telescopic mast 2 is attached with its base to the frame of the mobile trolley 1 and, in the extended condition, it is anchored by means of steel ropes 12 .
  • the telescopic mast 2 is installed on the trailer or it may be easily installed on a passenger car or a lorry.
  • the radar system 7 is based on the Doppler principle operating on the frequency of 24 GHz. Using patented technology, it has the ability of a fast configuration and it is suitable for detecting vehicles on roads of all classes.
  • the sensor is suitable for use in mobile applications or in on-line applications, e.g. in linear traffic control. It may be remotely control, configured and upgraded.
  • the radar system 7 is connected to the control unit 14 via an evaluating unit 13 .
  • the evaluating unit 13 is connected to a modem 15 for data transmission.
  • a resistant notebook was chosen having a touch sensitive screen and a high resistance in compliance with military standards.
  • the notebook can be connected to almost any wireless network. Thanks to its resistance and high communication flexibility, the device is absolutely suitable for an implementation into a trailer which will be subjected to various climatic and other effects, for example in the course of transport.
  • the device may be remotely controlled by means of a touch sensitive display designed as a highly luminous display and its visibility is therefore not reduced even when exposed to direct sunlight.
  • the notebook was specially developed for mobile outdoor applications and its power output was therefore considerably reduced in comparison with standard computers.
  • the unit 9 for wireless data transmission and reception is provided with various technological features for wireless data transmission, namely for the transmission of data within a distance of up to 20 km, transmission of data into internet network and for the check-up of localization, for example by a GPS system.
  • the station Up to a distance of 20 km, the station is equipped with WiFi technology, thanks to which the station can communicate with mobile telematic stations, which detect vehicles in real time and consequently send the obtained information to the evaluating unit, which is located on the trailer with display panels by means of Bluetooth technology - so there is a possibility of communication by means of PDA without having to open the compartment on the trailer and by means of radio data transmission. It is also possible to transmit data even from more distant locations without using the GSM network. This property offers the possibility of transmitting data from by-pass routes to the displaying devices on highways to inform drivers about actual arrival times from the by-pass routes.
  • a reliable, mobile power source is used as a source of energy. It is a methanol burning device. In course of the combustion, no harmful substances are produced and the device is ready to operate in the so-called hybrid mode in combination with solar collectors. The device is very quiet and safe in comparison to power generators of smaller dimensions.
  • the equipment recharges the batteries, if they reach the pre-set limits.
  • the battery status is displayed on any connected computer.
  • the equipment also comprises a GPS device and a GPRS modem for remote communication.
  • the methyl alcohol generator operates under any climatic conditions.
  • IP camera 3 was chosen with a built-in video analyser to launch alarm in case of unusual events, as for example a stationary vehicle, an oncoming vehicle etc.
  • the camera 3 was selected for the purpose of using the state-of-the-art video compression for the transfer of data of lower resolution even via the wireless technology CDMA and GRPS.
  • the IP technology enables to follow the image from any location of the installation in any location around the world provided with internet access.
  • the data transmission by means of wireless technology is possible thanks to the video format - MPEG-4.
  • a possibility of a remote control of the camera 3 and of zooming is implied.
  • the camera 3 used in the preferred embodiment had following characteristics: Virtual rotation/inclination/zooming in the main display and four user-defined areas in a standard JPEG format, digital image stabilization, flexibility of the whole solution, easy installation and operation, which is a substantial feature of mobile applications, adjustable resolution and frame frequency, possible data transfer by means of WiFi.
  • the modular mobile telematic station is a system providing adequate data sources offering ample use in traffic. It may be used for providing on-line traffic information in critical locations, where it can act as a substitute of missing stationary telematic infrastructure or it may temporarily collect data regarding the respective traffic situation as well as meteorological information in a given profile of road network. Similar systems can also find their application in sites of working zones for video supervision or they may form a component part of more complex control systems etc. Another suitable use seems to be in by-pass routes, seasonal routes or in case of special activities.
  • Mobile trailer 1 with detectors is provided with wireless data transmission technologies with the possibility of transmitting images from the location in which the system is employed.
  • the station is IP-addressable and it can offer data in various formats, which can be specified according to local requirements.
  • it communicates with mobile display units to enable change of pictograms, messages.
  • a GPS unit for supervising the localisation also forms part of the system.
  • a power supply is formed by the batteries, which will be recharged by a hybrid remotely controlled system generating electrical energy by means of methyl alcohol fuel elements and solar panels. Such a power supply may extend the working time of the system without any attendance for up to 40 days.
  • Advantages of the telematic station consist in the possibility of a ready and easy launching of the system into operation, in the video supervision of the working zones and in the fact that they may form part of larger systems to control the traffic flow with the possibility of detecting traffic accidents in critical locations. Further advantages consist in the video supervision of the traffic operation, wireless communication with other stations, in the traffic census, data regarding the road surface temperature, air temperature, wind strength and direction and the noise.
  • An active management of the traffic flow is implemented as a static application, which is permanently installed in a definite section of the road network, mostly in highways and in the neighbourhood of big cities.
  • the designed mobile system can be theoretically operated as a mobile active management of the traffic flow in a small section of the road system, which can be variably complemented by required telematic elements and it is relatively easy to transfer it to other required locations.
  • the mobile telematic applications are usually used in locations lacking active management of the traffic flow or they are used as its effective complement. In certain segments they form a sort of a superstructure, which is flexibly available to offer actual information to the drivers. It is especially the case of the working zones, in which the need of real information is constantly increasing due to the ever-increasing traffic intensity. It is understandable that especially the working zones are seldom fitted with permanent detectors in spite of the fact that they form a critical section of the road network.
  • the present invention can be used to provide detection systems to control in particular the automobile traffic.
