  route and conductors terminating at the transmitters.

  For the verification of mechanical recorders we know, among others, transmitters of number of revolutions, which are not usable for the verification of recorders of

  Electronic traffic control points are known

  motor vehicles, with which it is impossible to control all the functions of road recorders and

  involve a very costly process in manpower and energy.

  a location of the defects being carried out.

  This objective is achieved in accordance with the

  of the road recorder, including drivers of impulse

  between the road recorder and the transmitters, is carried out by means of a device which, inter alia, simulates

  main features of the route recorder.

  The complex verification of the main functions

  many laps are verified statically by the introduc-

  tion of successions of constant pulses, that dynamically

  by the introduction of a succession of variable pulses.

  The indication of path sections is checked by counting

  pulses entered in the Simul-

  At this time, the successions of pulses thus introduced are recorded on a test chart disk, where after the end of the verification, the fixed values for the speed and / or the number of revolutions, the recording of the section of tra Jet. and dynamic values for speed and number of revolutions,

  may be read as a form of triangular functions

  the corresponding cycle time of the verification step.

  During the functional verification of the indica-

  speed and number of revolutions, the speed limit and speed limit indications of the road recorder,

are also verified.

  By applying a measurement voltage on the pulse conductors between the route recorder and the transmitters, a short circuit check verification of

  these pulse drivers with simultaneous indication of

  the process according to the invention and the

  positive in accordance with the invention, will be described in more detail with reference to an exemplary embodiment shown in the accompanying drawings in which: Figure 1 is a complete circuit diagram of a road recorder with the transmitters, 4.-

  Figure 2 is a circuit diagram of the dis-

  positive for the implementation of the process according to the invention,

  Figure 3 is a block diagram of the

positive according to the invention.

  According to FIG. 1, the road recorder 1 is connected via a plug connector 2 with

  the pulse drivers 3 and these are connected by the

  other plug connectors 4, 5 with the emitters 6, 7.

  To check the record

  1, including the verification of drivers

  pulses 3, the device 10 is firstly, as the re-

  shown in Figure 2, plugged into the mounting assembly

  Route recorder 1, pulse conductors 3 and transmitters 6, 7 For this purpose, the pulse conductors 3 are split up

  at the entrance of the road recorder 1 t, that is to say that the

  plug connector 2 is disconnected, and the left and right halves 8, 9 of this plug connector 2 are respectively connected

  to the device 10 The connector plug 4, consisting of me-

  left and right 11, 12, and the plug connector 5, con-

  left and right halves 13, 14 are also disconnected.

  that is, the pulse drivers 3 are

  at the input of the emitters 6, 7 and the left halves 111, 13 of the plug connectors 4 and 5 are connected to adapters

  15, 16 in which there are combinations of resistors.

  dynamic functional control of indica-

  speed and number of revolutions is introduced by introducing

  in the route recorder 1 of a succession of variable pulses emitted by the voltage-controlled frequency generator 21 The indications of speed and number of revolutions are simultaneously verified both by static functional control and by dynamic functional control. sequences of constant pulses introduced into the Route Recorder 1, during the static functional check, correspond to

  fixed values for speed and number of revolutions

  variable impulse input introduced into the route recorder 1 during the dynamic functional check corresponds to the production of a smoothing value for the speed and the number of revolutions During the dynamic functional check, the succession of variable pulses runs value range from zero value up to the maximum value and back to the zero value of the speed and revolutions indications, while simultaneously the speed limit and revolutions value indications of the road recorder 1,

are checked.

  The verification of the indication of path sections is carried out by counting the pulses introduced into the route recorder 1, these pulses being generated

  and counted by the transmitter and pulse counter 23.

  The device 10 further comprises several window discriminators 22 for the control of passage and

  short circuit of the pulse conductors 3 between the recordings

  1 and the transmitters 6, 7, a fault display being realized simultaneously with this control For the execution of this control step, a measurement voltage is applied

  from the device 10 on the pulse conductors 3.

  The cycle time and the succession of the control steps are determined at will from the control unit 17, a 5.-

  functional indication taking place for each step of con-

  control the exit doors 18, 19 of the control unit 17, make the connection to the road recorder 1 or else to

pulse drivers 3.

  The illumination check and the verification of the auxiliary power supply of the route recorder 1 are carried out when the device 10 is connected.

  according to Figure 2, by simple optical indications.

  The check of the recording is carried out by means of a chart-test disc placed in the recorder of road 1 before the beginning of the control After the end of the check # the fixed values for the speed and / or the number of turns ,

  the section of the trip section and the group markers

  pes of working time, as well as dynamic values for speed and number of revolutions, are likely to be read

  as triangular functions.

  Advantageously, the edge voltage of the

  vehicle is used for the power supply of the

tif 10.

  The voltage available at the output of the power supply unit is independent of the value of the

  edge voltage applied to this unit.
