Definitions

  • the invention relates to a traffic signal system with an intersection device, which has a microcomputer for signal control and protection and data transmission devices, and with signal generators, which have switching and monitoring devices for the signal lamps and are connected to the intersection device via power supply and control lines.
  • Such a traffic signal system is known from DE-A 32 30 761.
  • a traffic signal system is described there, the signal generators of which are fed via a single two-wire line.
  • Each signal transmitter has a lamp switch and a monitoring circuit and a switching device (switching device) in the respective lamp circuit.
  • the switching device of each signal transmitter is in each case connected to the control unit or. Junction device connected.
  • the lamp switches are controlled by the switching device, which receives the switching commands from the central control device via the respective signal line.
  • the states of the monitored lamp circuits are transmitted to the control unit via the switching device and the signal line. In this known system, it is necessary to route a signal line from the control unit to each signal transmitter.
  • the object of the invention is to develop and design a traffic signal system described above so that small pedestrian systems up to large intersection systems can be created with the same modules.
  • the cabling effort is to be further reduced and nevertheless fast and reliable data transmission between the crossing device and the individual signal transmitters to be guaranteed.
  • This object is achieved in a traffic signal system described above in that all signal transmitters are connected to a single wiring harness with a power supply line and a data line, that almost every signal transmitter has a receiving and transmitting device with a respective address decoder and one quartz crystal each for receiving the control commands and Sending the feedback in the form of data telegrams with a high bit rate, with the data transmission in each half-wave outside the zero crossing of the AC supply voltage, that the control command telegrams each have only the address of the signal group, that a specific time window is provided for the feedback for each signal generator that in each signal transmitter by means of monitoring devices all signaling states (signal lamp currents and voltages) are monitored and transmitted to the crossing device, and that in each signal transmitter A monitoring switching device is provided, which switches to dark or flashing yellow with intrinsically safe switches when the data telegram pulses are absent in the signal transmitter concerned.
  • the traffic signal system has the advantage that all signal transmitters can be constructed in the same way and have the appropriate switching, monitoring and transmission devices and are only connected to the crossing device with a single line. All signal transmitters of a node can thus be connected to the crossing device via a single line routing, which can be designed as a ring line. This considerably reduces the installation effort.
  • the control commands and the feedback are transmitted in the form of data telegrams with a high bit rate compared to conventional transmission methods in road traffic technology.
  • the control command telegram only has the address of the signal group because the command to all signal transmitters in a signal group is the same.
  • a separate time window is provided for the feedback of the known monitoring of the signal states for each signal transmitter, so that no separate address formation is required.
  • a monitoring switching device is provided in each signal transmitter, which switches to dark or yellow flashing via the intrinsically safe switch if there are no pulses.
  • the monitoring switching device which can be formed by a relay arranged on the data line with associated diodes and capacitors and corresponding relay switching contacts, expediently has an additional charging capacitor which is arranged in parallel with the relay contact and which can also be charged when the traffic signal system is switched off, if only one only data telegram is sent from the crossing device to the signal transmitter to be tested.
  • an additional charging capacitor which is arranged in parallel with the relay contact and which can also be charged when the traffic signal system is switched off, if only one only data telegram is sent from the crossing device to the signal transmitter to be tested.
  • a data telegram has a specific number of addresses and parity bits as well as control command bits.
  • the address of the signal group can be formed by 4 bits plus 3 parity bits and the control command can have 3 bits corresponding to the three signal colors plus one or more reserve bits.
  • the data telegram for the feedback of the respective signal transmitter also has one or more reserve bits in addition to the respective status bit of the corresponding signal color.
  • this structure of the data telegrams according to the invention allows two signal transmitters assigned to one another to be controlled with only one data telegram.
  • This data telegram has only one receive address, separate feedback of the voltage values and current values for the two different signal transmitters.
  • signal generators that directly belong together can also be controlled with only one data telegram, with the feedback of the voltage values also taking place jointly, but the feedback of the current values taking place separately.
  • the reserve bit is expediently used for the feedback of the second current value.
  • the traffic signal system according to the invention also advantageously allows the electronics for a vehicle signal and a pedestrian signal transmitter, both of which are attached together on the same mast. In addition to saving electronics, this also results in faster data transmission.
  • a similar measure can also be carried out for signal generator groups which do not show the same signal pattern, for example if not only the information red, yellow or green is transmitted for each vehicle signal group, but also red or green for the hostile one Pedestrians, ie for the pedestrian signal group, is transmitted, the two different signal groups being controlled under only one address, namely that of the vehicle signal group. Only two bits are required for the transmission of the control command instead of the one reserve bit, as well as for the feedback from the respective signal generator.
  • a special cable can be provided for the wiring harness, in which a pair of high-current wires and a shielded two-wire communication line or a coaxial line are used.
  • one or more vehicle detectors which are arranged either on the signal mast or in the roadway, can also be connected to the wiring harness and can be controlled accordingly with the pulse telegrams.
  • the vehicle detectors are queried with addressed data telegrams in each half-wave in the area of the zero crossing of the supply voltage.
  • the traffic signal system according to the invention can also be operated, as is known per se, in low-voltage technology, with a network transformer being arranged in each signal transmitter.
  • a network transformer being arranged in each signal transmitter.
  • the switching devices for the lamp current are formed by simple transistors. This has the advantage that relatively simple monitoring of the signaling states is possible, and that automatic testing can also be made possible by switching a hostile signal image for a short time, ie in the millisecond range, which is monitored for the actual occurrence in the crossing device.
  • the information for the signal group is only completely received and only then the transistors of the lamp circuits are switched simultaneously, so that one lamp is switched off and another lamp is switched on and the current pulses of the load surges are thereby largely avoided will.
  • the address of the control command for the signal group ADSGR consists of four bits with three subsequent parity bits PAR. This is followed by the actual control command with one bit each for the signaling colors red, yellow, green and a reserve bit RE.
  • the feedback RM of a signal generator SGE1, SGE2 ... takes place in a respective time window ZF1, ZF2 etc. and has four bits, 1 bit for each signal color plus a reserve bit RE.
  • the data telegram to the signal transmitters therefore consists of an address part with 4 bits plus 3 parity bits and the command part with 4 bits, 5 bits can also be provided, so that a check bit can also be inserted.
  • a data telegram which controls a signal group with three signal transmitters, requires 23 bits, ie the data exchange is 0.23 ⁇ s at a data transmission speed of 100 kilobits per second. If reserves are also taken into account, the entire activation of, for example, 15 signal groups with reserve bits for synchronization takes about 4 ms.
  • This data telegram is transmitted in the half-wave around the peak of the AC supply voltage, as shown in FIG.
  • FIG. 2 shows a data telegram similar to that shown in FIG. 1, but with the difference that both a vehicle signal transmitter Fa and a pedestrian signal transmitter Fu are controlled with a data telegram at one and the same address.
  • the address formation is the same, only the control command transmission is expanded by 1 bit.
  • 3-bit information is required for the vehicle signal transmitter Fa and two bits are transmitted for the pedestrian signal transmitter Fu.
  • the data telegram looks similar when it is reported back.
  • the monitoring data of the signal generator SGE1 addressed with a single address, in the present case the vehicle signal generator are transmitted to the crossing device.
  • the 3 bits of the vehicle signal transmitter Fa are followed by 2 bits for the pedestrian signal transmitter Fu.
  • FIG. 3 shows how the individual data telegrams for the control commands for the signal group and for the feedback signals from the individual signal transmitters are transmitted within the sine wave of the AC supply voltage at the apex SP.
  • FIG. 3 also shows data pulses that are transmitted around the area of the zero crossing ND, namely a data telegram designated DA for the detector interrogation, around vehicle detectors that are connected to the same wiring harness and are assigned to a signal transmitter, for example by a detector loop in the lane led to the signal mast or by mounting an infrared detector on the signal mast.
  • the data telegrams can be structured similarly to those for the control command of the signal groups.
  • FIG. 4 shows a basic circuit diagram of a signal transmitter of the traffic signal system according to the invention.
  • the signal generator SGE is supplied with an AC voltage of, for example, 220 V via the mains line NL.
  • a transformer TR is arranged, which is followed by a rectifier circuit GL, which supplies the individual signal lamps LA for red, yellow, green, green.
  • a switching transistor LS1 to LS3 is arranged in each case in the lamp circuit.
  • the lamp voltages and also the lamp currents are monitored here via the resistor RÜ and these signaling status data are fed to the transmitting device SE.
  • the individual lamp circuit switches are controlled on the basis of the control commands which the receiving circuit EM receives.
  • the control commands STB reach both the receiving device EM and the transmitting device SE via appropriate electronic decoupling elements. each of which has an address decoder ADC. Furthermore, a separate quartz crystal Q is assigned to both the receiving device EM and the transmitting device SE.
  • the transmitting device SE transmits the feedback data RM to the data line DL via a suitable coupling element, here in the form of a transistor.
  • a monitoring switching device ÜSV is connected to the data line DL, which inter alia has a relay Ü to which a first switching contact Ü1 and a second switching contact Ü2 are assigned.
  • the first switch contact U1 is in the circuit, here at the positive pole of the rectifier circuit GL in the lamp circuit.
  • the charging capacitor C is connected to a discharge resistor R.
  • the relay Ü remains activated as long as there are pulses of the data telegram on the data line DL.
  • the relay contact Ü1 is therefore closed.
  • the relay contact Ü1 opens and the signal transmitter is switched off, or if it is provided, the second relay switching contact Ü2 switches to yellow flashing by switching the yellow lamp GE to the blinker BLI.
  • the monitoring relay Ü does not respond due to the single pulse telegram.
