Definitions
- the invention relates to a device for photographically monitoring an intersection controlled by means of a traffic light system, comprising:
- This behavior contrary to traffic may consist of the vehicle entering an intersection during the blocking phase. Then the photographic camera is triggered by a signal when a contact threshold laid in the roadway is passed. The behavior contrary to traffic may also consist in the vehicle driving too fast. In this case, the photographic camera is triggered in that two contact thresholds laid one behind the other in the roadway are passed over within a predetermined period corresponding to the permissible maximum speed (DE-A-10 78 797) or AT-A-225 077). The two contact thresholds laid one behind the other in the direction of travel serve exclusively for speed measurement. 0
- DE-C-2 356 331 discloses a device for the photo-graphic monitoring of traffic light-controlled intersections with a photographic camera that detects the intersection and a sensor that responds to the entry 5 of a vehicle into the intersection and a sensor signal by means of a detector circuit delivers.
- Aritaausl sevoriques is formed by a signal via a first gate circuit triggered by the first trigger signal for triggering Fühler ⁇ a first recording Q Toggle controllable.
- the first gate circuit can be switched through by a signal from the traffic light during its blocking phase.
- a timer is triggered which switches for a predetermined delay time.
- a second trigger signal which acts on the camera trigger device, is generated by the timer 4 "Triggering of a recording is generated.
- the " first gate circuit is blocked from the triggering of the first recording until the end of the second recording. In this way, a second vehicle entering the intersection shortly after the first triggering vehicle cannot immediately generate a trigger signal before the cycle initiated by the first vehicle and consisting of the first and second recordings has ended.
- the sensor signal rises at the same time on a second gate circuit which is switched through during the blocking time of the first gate circuit.
- the output dn 'eser second gate circuit is switched on, also ge an signalsver ⁇ hesitant timing element with a delay time longer than the time required is.t for the two images to the camera triggering device.
- the sensor pulse of the second vehicle is thus stored, so to speak, until the first two recordings, including film transport, have definitely ended. Then a third picture is taken. The second vehicle is then certainly visible on one of the two recordings triggered by the first vehicle and additionally on the third recording, so that two recordings are also made of the second vehicle.
- US-A-3 858 223 and DE-B-2 307 217 also show a device for photographic monitoring of traffic-controlled intersections, in which a vehicle triggers two shots in succession when entering the intersection.
- a second sensor is provided in a lane crossed to the lane to be monitored, through which the camera triggering device can be controlled via a gate circuit which is switched through during the delay time between the first and second recording.
- fast-moving vehicles are detected which enter the intersection during the blocking phase and immediately turn into a carriageway crossed to the blocked carriageway before the delay time of the timer expires and the second recording is triggered.
- an additional recording is triggered via the second sensor before the specified delay time expires. This recording then captures the turning vehicle.
- two sensors lie in mutually crossed lanes.
- the use of the second sensor has the special purpose of detecting turning vehicles. Vehicles driving straight ahead do not respond to the second sensor and are detected by the recording triggered after a predetermined delay time.
- the vehicles are photographed from behind, the rear license plate appearing on the recording.
- the driver of the vehicle is generally not recognizable in such recordings.
- Such a frontal photograph if it is carried out with flash lighting, requires special precautions to avoid dazzling the driver and also ensure that the driver can be recognized through the front windshield of the vehicle.
- a red filter is therefore usually placed in front of the flash and camera and a red-sensitive film is used.
- the known devices can also fail in slow-moving vehicles. If the vehicle has triggered the sensor in slow travel and the delay time has started to run, then it may happen that at the time of the second recording this vehicle is not yet in the danger zone. The vehicle can then be used during the Continue the blocking phase over the intersection without this being proven by the recordings.
- the distance of the photographed vehicle from the camera depends on the speed of the vehicle. This is particularly disadvantageous in frontal photography, where it is important to identify a person behind the windshield in the picture in the case of frequently unfavorable lighting conditions. Disclosure of the invention
- the invention is based on the object of designing a device of the type mentioned at the outset such that vehicles which pass the intersection very quickly during the blocking phase and vehicles which pass the intersection very slowly during the blocking phase are evidentially in the danger zone can be photographed. 0
- the means for generating the second trigger signal contain the second sensor which responds to the passage of the vehicle through a second position lying in a straight line behind the first position and by means of which a second sensor signal can be connected to the signal processing means.
- Both the fast and the slow-moving driver are photographed within the danger zone where the second sensor is arranged. Both can therefore be proven in a verifiable form.
- the camera is also dependent on one
- I ⁇ blocking phase signal controlled, which is picked up by a traffic light system. A camera is triggered when the first and the second sensor respond, while in DE-A-1 078 797 the camera is triggered only after both sensors are inside
- the second sensor responds to the passage of the vehicle through a position lying in a straight line behind the first sensor.
- the second sensor is therefore not in a lane crossed to the monitored lane.
- the invention is the detection of very slow and very fast moving vehicles, not as in DE-B-2 307 217 and US-A-3 858 223 the detection of turns.
- Fig. 1 is a schematic representation of a traffic light controlled intersection with a photographic surveillance device.
- Fig. 2 shows a diagram of the processing medium at a Signalver ⁇ About ⁇ wachungsvortechnische of FIG. 1.
- 10 denotes a street intersection in which two streets 12 and 14 intersect.
- the intersection 10 is controlled by a traffic light system, of which only one traffic light 16 is shown in front of the intersection in the street 12.
- a pedestrian crossing 18 is marked in the area of traffic light 16.
- a road marking 20 for two lanes with a stop line is applied on the road 12 in front of the pedestrian crossing 18.
- a first sensor in the form of an induction loop or the like 22 is inserted in the direction of travel behind the marking of the pedestrian crossing 18 and behind the street marking 20 in the carriageway ceiling.
- a second sensor 24 embedded in the road surface is arranged in the danger area of the intersection 10 in a straight line behind the first sensor 22.
- the processing means by means of signal signals from sensor signals of the sensors 22 and 24 and a blocking phase signal 7 0
- the traffic light system 16 is controlled i.st. If a vehicle passes the induction loop 22 during the blocking phase, when a blocking phase signal is generated, the camera 26 is triggered to take a first picture. A second recording is triggered when the vehicle travels through the second induction loop 24, that is to say is in the danger zone of the intersection 10. However, this triggering of the second recording takes place only if the first recording has been triggered beforehand by passing over the induction loop 22. This prevents the camera from being triggered by cross traffic in street 14. So it becomes the second sensor 24 only by the first sensor signal
- FIG. 1 A second alternative is indicated in FIG. 1.
- a photographic camera 28 set up for the frontal photographs of the 20 * vehicle can also be arranged such that it photographs the vehicle from the front against the direction of travel.
- a vehicle 30, as indicated in FIG. 1, travels at a very high speed over the intersection 10 during the blocking phase and, according to the prior art, the first and the second recording are triggered one after the other at a fixed time interval, then the vehicle 30 can be so far away from the 3 Q camera 26 that a flawless
- both the carriage 30 and the carriage 32 would essentially be in the same position in the danger area of the intersection 10 and at an optimal distance from the camera 26 or 28 photographed.
- the first sensor which contains a detector circuit (not shown), is connected to an input 34.
- An optocoupler is provided between the input 34 and the signal processing means. This optocoupler causes an inversion of the signal: a positive pulse is converted into a negative pulse. The optocoupler is therefore symbolized by an inverter 36.
- the inverted sensor signal is converted into a perfectly processable rectangular pulse by a pulse shaper 38. This is known technology (see US-A-358 223) and is therefore not described in detail here.
- the sensor signal thus obtained is present at an input 40 of a flip-flop 42.
- the flip-flop 42 is usually composed of two NAND elements 44 and 46.
- the output of the NAND gate 44 is connected to an input 48 of the NAND gate 46.
- the output of the NAND gate 46 is connected to an input 50 of the NAND gate 44.
- the input 40 forms a further input of the NAND gate 44.
- the NAND gate 46 has a second input 52, via which the flip-flop 42 can be reset in a manner to be described.
- the NAND gate 46 has a third input 54, which is connected to an input 56 for a blocking phase signal.
- the signal present at the input 50 of the NAND gate 44 is connected to a reset input 56 of a counter 58.
- the "counter 58 is in a known manner he count as an electronic code formed of a réelle ⁇ write signal at an output 60 at a predetermined counter reading. This signal is connected via a resistor 62 and an inverter 64 to the second input 52 of NAND gate 46 switched in the flip-flop 42.
- the output signal of the NAND gate 46 which is present at the input 50, is also connected to an input 66 of a NOR gate 68.
- the second sensor 24 which contains a detector circuit (not shown), is connected to an input 70.
- the second sensor signal is applied to the second input 76 of the NOR gate 68 via an optocoupler (shown as inverter 72) and a pulse shaper 74 1 switched.
- the output of the NOR gate 68 is at an input 78 of a NOR gate 80.
- the signal present at input 50 of NAND gate 44 is also connected to an input 82 of an exclusive OR gate 84.
- the same signal is connected to an RC element, consisting of a resistor 86 and a capacitor 88 at the second input 90 of the exclusive OR gate 10.
- the output of the exclusive OR gate 84 is connected to the second input 92 of the NOR element 80.
- the output of the NOR element 80 controls a circuit 94 for generating a trigger signal for the camera.
- the output of the NOR gate 68 is also connected to the input of the inverter 64 ' via a line 96 and a diode 98.
- the counter 58 contains two counting stages 100 and 102 for counting seconds and tenths of seconds.
- the counter stage 100 receives an input signal with twice the mains frequency of 100 Hz.
- the counter reading is predetermined with diode arrangements 104 and 106
- the signal processing means described with reference to FIG. 2 operate as follows:
- the circuit 94 is controlled via the exclusive-OR gate 84 and the NOR gate 80, so that it outputs a trigger signal.
- the output of the exclusive OR gate 84 is normally zero, since in the static state with the capacitor 88 charged, both inputs 82 and 90 of the exclusive OR gate 84 are at the same potential. They are both connected to the output of the NAND element 46, although an RC element 86, 88 is connected upstream of the input 90.
- the output of the NAND gate 46 changes from the "H" state to the "L” state, the inputs 82 and 90 are temporarily at different potentials. The input 82 immediately goes into the "L” state, while the input 90 remains in the "H” state for a while because of the charged capacitor 88.
- the Exclusi v-OR gate 84 therefore outputs an output pulse when switching the flip-flop 42.
- a second sensor signal appears in the form of a positive pulse at the input 70. This positive pulse is converted into a negative pulse by the inverter 72.
- the input 76 of the NOR gate 68 therefore temporarily goes into the "L” state. If the first sensor 22 has previously responded, then, as described, the output of the NAND element 46 is also in the “L” state. This signal “L” is also present at the second input of the NOR element 68. If the input 76 also goes into the "L” state, the output of the NOR gate 68 goes into the "H” state. So there is a second pulse via the NDR gate 80 to the circuit 94, so that a second trigger signal to
- Triggering a second shot of the camera is generated.
- the input 52 of the NAND gate 46 is temporarily brought into the "L” state via the line 96, the diode 98 and the inverter 64.
- the flip-flop 42 therefore switches back to its initial state.
- the output of the NAND gate 46 goes into the "H” state.
- the output of the NAND gate 44 goes into the "L” state.
- the output of the NAND gate 46 therefore remains “H” even after the pulse at the output of the NOR gate 68 has ended, when the input 52 returns to the "H” state. Via the reset input 57, the counter 58 is reset to zero.
- a trigger signal is generated and a picture is taken. This is the normal way of operating.
- the signal processing agents are again in their initial state. If a sensor signal from the. second sensor -. $ 4 appears without the first sensor 22 having previously supplied a sensor signal, then the signal processing circuit is in its initial state when the second sensor signal appears, that is, the output of the NAND gate 46 is in the "H” state ". The output of the NOR gate 68 is therefore in the "L” state. This is independent of the state in which the input 76 of the NOR element 68 is.
- the second recording is triggered as soon as the vehicle passes sensor 24.
- the vehicle 32 remains in the position shown in FIG. 1 after actuation of the sensor 22, that is to say still outside the danger zone of the intersection 10, then the following occurs: the second sensor signal does not appear.
- the flip-flop 42 is not reset in the manner described via line 96, diode 98 and inverter 64 and the counter 58 is reset to zero.
- the counter 58 therefore continues to count until the preselected counter reading, which corresponds to a certain delay time, is reached. Then the input 52 of the flip-flop 42 is brought into the "L" state via the output 60, the resistor 62 and again the inverter 64.
- the vehicle 32 is photographed again in its position in front of the second sensor. It can therefore be demonstrated that the vehicle 32 did not enter the danger area of the intersection 10 but stopped behind the stop line but still in front of the street corner.
- a camera 26 can be arranged in the direction of travel in front of the intersection, which photographs the vehicles from behind, or a camera 28 can also be arranged in the direction of travel behind the intersection Intersection for the Frontal photographi be provided.
- a camera 28 can also be arranged in the direction of travel behind the intersection Intersection for the Frontal photographi be provided.
- the camera 28 can, if necessary, be controlled such that it is only triggered by the second sensor signal.
- a microprocessor programmed with suitable software can also be used as signal processing means.
