Definitions

  • the invention relates to a control system for roads and motorways adapted to display the traffic on determinate road and motorway routes, by signalling timely the traffic situation to suitable checking boards such for instance one or more operative rooms.
  • Control systems for checking the traffic on roads and motorways are known, which are constituted by towers or trestles equipped with television cameras positioned on particularly critical points for the road and motorways traffic, in order to signal timely and continuously the traffic situation to suitable traffic checking boards operatively connected to such control systems.
  • Such control system is substantially constituted by a plurality of detecting units 9, see Fig. 1, which are formed by one or more electronic displaying units 10 made preferably like television cameras, and operatively connected to an electronic control circuit constituted as it will be described later and formed by a plurality of electronic components, introduced on a corresponding series of containers 12 shaped preferably with the form of road signalizations or like a kerbstone, said displaying units being connected to an equipped operative room, in order to permit the personnel to display at will any point of the road which can be reached by the system television units, in order to detect the instantaneous situation of the road and motorway traffic.
  • Such television cameras 10 are connected, by means of a central control unit 14, with radio receiver and emitter units of radio signals formed by at least an emitting unit 15 and a receiving unit 16, performing the function to emit and receive signals with respect to a central operative room, and this transmission and reception of electromagnetic signals normally occurs either directly by a cable or by appropriate radio links (not shown), by Internet or by satellite or other suitable radio transmitter and receiver systems.
  • Such central control unit is arranged to control the different circuital components of the control system, by processing all the inputted and outputted coded informations, and also recognizing the inputted signals based on their codes, so as to control adequately the various circuital components, as well as checking if the interlocutor with whom the information exchange occurs, is enabled or not enabled to be connected to the control system, and finally by signalling the presence of any operative fault or failure of the same system.
  • the emitting units 15 are able to transmit both audio and television signals, such as for example images coded in a digital mode, or also on other adequate modes, thus without departing from the protection sphere of the present invention.
  • the receiving units 16 are arranged to receive radio signals which are decoded and used for activating the television cameras during operation thereof.
  • each detector 9 includes in its interior at least a sound alarm unit 21, adapted to emit a signal such as for example an audio signal when the television cameras are activated, so as to warn any person situated on the operative range thereof.
  • Each detector 9 is associated with an appropriate identifying code, in a manner to permit the identification thereof from the operative room, with consequent possibility of activating any detector and therefore, if this is the case, also a television camera associated therewith.
  • all the objectives 11 can be turned toward the zones to be displayed also in different manners, thus without departing from the protection sphere of the invention.
  • the present control system lends itself advantageously to be used also in combination with a traffic control system described and claimed with the Italian patent application n. TV2000A000063, filed on 1.6.2000 by the same Applicants.
  • Such control system is constituted substantially by a plurality of autonomous vehicle detecting units, disposed spaced away along the road and each comprising at least a control plant having an electric supply voltage included therein, which is co-operating with similar control plants of the other detecting units, and composed of sensor means of the presence of motor-vehicles, adapted to generate electromagnetic, luminous or sound signals etc..
  • timer means adapted to receive the signals coming from the sensor means and to let to pass only a signal of continuous type and longer than a pre-established time, on the condition of traffic jam
  • central control means formed by a main central control unit, adapted to receive the signals from the timer means and to activate alarm means on the condition of traffic jam, as well as adapted to reset themselves when such signals are ceased, said control plant being also adapted to control the alarm means in the case of receiving signals from the corresponding control plants of other detecting units on the condition of traffic jam.
  • Such central control means are connected to radio-transmitter units and radio-receiver units and, in the case of traffic jam detected by the sensor means, provide to generate a control signal which activates the radio-transmitter units, whose signal is transmitted to the radio-receiver units of detecting units adjacent thereto, which in turn transmit a corresponding impulse to the associated central control means for activating their own alarm means.
  • control system described by the patent application n. TV2000A000063 can be adapted to the present control system, so as to be used and operated in combination therewith, by utilizing (see Fig. 2) the same above mentioned components of the preceding control system, namely the sensor means 22 of presence of motor-vehicles, timer means 23, central control means 24, alarm means 25, 26, an emitting unit 27, 28 (respectively with high and low range of diffusion), and a receiving unit 29, 30 (respectively with high and low range of reception).
  • the emitting units and the receiving units are arranged in a different manner with respect to the corresponding emitting units and receiving units of the preceding patent application, so as to be compatible with the emitting unit 15 and receiving unit 16 of the present traffic control system, in order to be able to transmit and to receive coded informations with respect to this latter, which are able to recognize and activate only the detectors 9 of interest.
  • the presence sensor 22 provides to transmit the relative information, through the timer means 23, to the central control unit 24 and this latter provides to activate the alarm means 25 (or 26), by signalling therefore the danger situation to the adjacent units through the emitting unit 27, and such signal is received through the relative receiver 30 of the same units adjacent thereto.
  • the emitting unit 28 provides in turn to transmit by cable or by ether, as described in advance, an alarm signal to the devoted operative room, which signal includes the recognizing code of the activated control system, and such signal is detected from the operative room which finds this control system and provides for transmitting, manually or automatically, a signal coded with such recognizing code to the different detectors 9.
  • This coded signal is received and recognized only by the receiving unit 29 of the control system in accordance to the invention which corresponds to the transmitted code, which then will be detected and activated.
  • the relative central control unit 24 will operate, by means of the control means 20 of the actuator, the displacement of the box-like element 12 from its retracted position to its extracted position, with consequent orientation of the relative television camera toward the area to be displayed and transmission through the emitting unit 15 of the control system of interest of the operative room and in this manner in this latter there can be displayed the images and localized the exact point of the road portion being displayed and thereby detected in a very short time the situation and there can be decided in a time as short as possible the interventions to be done in the area of interest.
  • a road portion being watched through the detectors 9 in accordance to the invention of which the detectors 911 are not provided with television cameras while the detectors 91 are provided with television cameras.
  • the shot ranges 31, 32 and 33 of the various television cameras of which the range 31 lets it to reveal that in this case a single detector 9 and a single television camera are activated, for taking and displaying an accident occurred on a road, while the shot ranges 32 and 33 let it to reveal that a detector 9 provided with two television cameras has been activated, for performing the same traffic control function.
