  The transportable remote control panel of an object comprises a keyboard 1, an encoder 2 whose input is connected to the output of the keyboard 1, an AND circuit 3 whose first input is connected to

  the output of the encoder 2, a switch 4 whose

  8, whose second terminal is connected to the first

  first terminal of the stabilizing element 9. The second terminal of the stabilizing element 9 is connected to the neutral bus 11 which are also connected.

switches 4 and 6.

  The transportable remote control unit of an object also comprises a threshold circuit 12 whose inputs are connected to the terminals of the load-absorbing element 8, a flip-flop 13 whose synchronization input C is connected to

  the output of the threshold circuit 12, its input of information

  D being connected to a first terminal of

  the stabilizing element 9 while its output to

  version is connected to the second input of the cir-

cooked AND 3.

  The transportable remote control panel of an object further comprises a pulse former 14 whose input is connected to the second terminal of the power source 10 and whose output is

  connected to the reset input R of the.

  flip-flop 13 whose direct output is connected to -

  the control input of the switch 6.

  The threshold circuit 12 is formed of a tran-

  sistor 15 (FIG. 2) whose base is connected, via a resistor 16, to the second terminal of the element

  absorption of charge 8, the transmitter of the

  tor 15 being connected to the first terminal of this element 8. Between the collector of the transistor 15 and the neutral bus 11 are connected two resistors

  17 and 18. The connection point of resistor

  17 and 18 is connected to the synchronization input

C of the flip-flop 13.

  The pulse former 14 has, for example, the form of a differentiating circuit comprising a capacitor 19 (FIG. 3), a first terminal of which

  is connected to the second terminal of the power supply

  tation 10 and a resistance 20 of which a first

  terminal is connected to the second terminal of the condensa-

  19 and is connected to the reset input of the flip-flop 13. The second terminal of the resistor 20

is connected to the neutral bus 11.

  Switches 4 and 6 are made in the same way, each having a transistor 21

  (Figure 4) whose base is connected via a resistor

  22, at the output of the ET 3 circuit or at the output

  direct connection of the flip-flop 13, whose collector is connected to the input of the emitter block 5 or to the input of the indicator 7 and whose emitter is

connected to the neutral bus 11.

  The transportable remote control console

works the following way.

  When the desk is switched on, the

  Pulse 14 (FIG. 1) produces a short pulse of voltage, setting latch 13 to

  state 0. If the power source 10 is charged

  the voltage drop at the absorption element

  charge 8 is sufficient to make the

  sistor 15 (FIG. 2) and consequently at the synchronization input C of the flip-flop 13 (FIG. 1)

  appears a "1" and the latch 13 keeps, at its

  direct tie, the "0" and at its reversal exit, the

  "1" set when the console is switched on.

  The present of "1" at the second input of the circuit AND 3 allows the passage of the instructions for controlling the output of the encoder 2 on the control input of the switch 4, which switches the block

  transmitters 5 in accordance with the orders received from the

  1. Indicator 7 is in the disconnected state because

  that at the control input of the switch 6 is

  plicated a "0" and the switch 6 is not conductor. The discharge of the accumulator battery is accompanied by a sudden increase in its

  internal resistance, which causes declines

  accumulator earth 10 decreases, the decrease value of the voltage drop increases and happens

  finally the moment when the transistor 15 is blocked (FIG.

  re 2). In the off state of the transistor 15 corresponds the presence of "0" at the synchronization input C of the flip-flop 13 (FIG. 1). Therefore, the

  sound with the control object is thus cut off, and the object to be controlled stops (the latter is not

  pas'représenté). Indicator 7 indicates that the

  is not due to a defect in the communication system.

  but is related to a decrease in the charge of the accumulator battery. In order to continue working in remote control mode, the operator must replace the storage battery 10. At the

  restarting the transportable tele-

  command, flip-flop 13 goes to state "0" and the

the console operation resumes.

  The keyboard 1, the encoder 2, the transmitter block

  5, the power source 10, the flip-flop 13 and the indicator 7 can be made by any known method.

  In the portable transport console

  the automatic shutdown of the transmitter block 5, main energy consumer, is ensured in case

  of the exhaustion of the load of the food source

  10. As the portable transport console

  control can not operate while the transmitter block 5 is stopped, the operator replaces the power source 10 with a source, thanks to which he is warned of the excessive discharge of the source 10 and is assured the longevity of it, as well as the reliability

  functional function of the transportable telecom-

mande.
