Definitions

  • the invention relates to a diagnostic method for decentralized traffic signal systems for road traffic with a signal protection and evaluation module in a node control unit and with several peripheral modules called PLUS modules and sensors, pedestrian push buttons, vehicle detectors and associated data transmitters and receivers, and with transformers and Rectifiers for associated signal generators with signal lamps on respective signal masts, the node control device being connectable to the modules with an energy and data line.
  • German patent application DE-A-39 10 864 published May 23, 1990
  • the light signal system having features as shown in the preamble of claims 1 and 7.
  • the diagnostic method according to the invention is provided for such light signal systems.
  • the object of the invention is to avoid the disadvantages described above and to provide a diagnostic method for decentralized light signal systems which allows a reliable test which can be carried out in a short time.
  • the individual modules and the lamps and other elements connected to them are completely checked for functionality and correct wiring directly on the signal mast using a dedicated, network-independent diagnostic device.
  • a connection from the individual modules to the node control device is not required. This includes checking the function of the modules, the correctness of the addresses according to the site plan, the function and the location of the lamps. Since the diagnostic device is battery operated, no mains voltage is required so that the node control device does not have to be connected yet. The signal generators do not have to be covered, because the man who carries out the test on the signal mast can immediately see the right signal generator lighting up.
  • the method according to the invention has the advantage that the effort for checking the signal paths and testing the modules is considerably reduced and that troubleshooting is simplified.
  • the module to be tested is expediently connected to the diagnostic device and the type of module and the corresponding addresses are entered using a keyboard according to a predetermined site plan.
  • the test process is then started and the test result is shown and acknowledged on a display of the diagnostic device. This way it will also be the turn after all the lamps connected to a module are tested for their correct connection and functionality, the lamp being tested lights up briefly, for example for 250 msec.
  • the signaling chamber is generally open so that the brief flashing can be easily observed.
  • testing the lamp on the diagnostic device indicates that the lamp is controlled correctly and the switching information is correctly reported. Further details and advantages result from the subclaims and the description.
  • a particular advantage of the diagnostic method according to the invention is that after the module test has been completed, the connection to the node control unit is established and the connection and the data transmission from the control unit to the individual modules can then be tested on the control unit. Since the data supply for the signal protection in the node control device has already been checked in the factory, the light signal system can then advantageously be put into operation without risk after this test.
  • the functionality of the system can be fully tested in a simple manner with just one man before the system is started up or maintenance is carried out.
  • the PLUS module test is carried out on the mast immediately after installation.
  • the modules to be tested are either assigned to the lamp switches and sensors, the pedestrian push buttons or the vehicle detectors.
  • the modules and the lamps connected to them are completely checked. This includes checking the function of the modules, the correctness of the address according to the site plan, the function and the location of the lamps.
  • the diagnostic device is expediently portable, splash-proof and battery-operated. This makes it possible to test the modules and the lamps and elements connected to them during assembly when the mains voltage is not connected.
  • the diagnostic device is connected to a module or to the data line of the node control device via a longer, flexible cable, so that a convenient location for the diagnosis can be found even in exposed installation locations.
  • the diagnostic device is operated, for example, menu-driven via a keyboard and a display.
  • the type of test, the type of module, the addresses and the lamps to be tested are selected and the test procedure is triggered by pressing a start button. After the test has been completed, the test result is shown on the display and acknowledged acoustically.
  • additional tests can be carried out automatically, invisible to the examiner, for example whether a module only reacts to its preset address and not additionally to others.
  • it is tested whether the sum check of the telegram traffic is working properly. The entire hardware is therefore largely tested with this diagnostic procedure.
  • the diagnostic device itself is monitored so that it is ensured that all of these tests can also be carried out.
  • the level of the command and message telegrams is also measured in all of these test procedures. It is also checked whether there is a terminating resistor in the data line or not, if so, whether it has the required value. The results of the level measurement and the terminating resistance measurements are shown on the display.
  • the functionality of the modules is first tested.
  • the lamp connector does not have to be yet be plugged in.
  • the lamp connector is plugged in when the signaling chamber is open.
  • the lamps now connected to the module are now tested one after the other by selecting a lamp on the diagnostic device and triggering the test process by pressing a button.
  • the lamp to be tested lights up once for 250 msec. on. The installation of the lamp in the correct chamber can thus be checked. At the same time, it is tested whether the module controls the lamp correctly and reports the switching information.
  • the display of the push button messages can be selected and tested.
  • the detector messages are tested and displayed.
  • the plugs of the data line and the power supply are connected by the control unit and the open signal transmitters are closed. A test for data transmission from the control unit to the individual modules and vice versa can then be carried out.
  • a line is checked that can have up to 15 modules.
  • the diagnostic device is plugged into the node control device, the data connection to the actual control device being interrupted by opening, for example, a disconnect terminal.
  • the data traffic to the individual modules of a line takes place only through the diagnostic device.
  • the addresses of all modules connected to a line are first determined. These addresses determined and determined by the diagnostic device can now be checked with the help of the site plan. Then the data transmission to the individual modules is diagnosed. The transmission and reception levels are displayed. It is also checked for the correct termination of the line with a correct terminating resistor.
  • the diagnostic procedure also allows listening in when the system is fully operational.
  • the diagnostic device is connected to the node control unit.
  • the messages from the loop detectors, the messages from the pedestrian push button modules can be displayed, the respective levels of the module telegrams are measured and the activated modules are displayed in terms of addresses.
