Definitions

  • the present invention relates to a device for controlling the use of a locomotion machine.
  • a rental locomotion machine It is more and more common to use a rental locomotion machine. For example, you can hire an unmanned helicopter for occasional transportation or handling. The operator can hardly demand anything more from the person wishing to rent the locomotion machine than the possession of a pilot's license corresponding to the type of aircraft. If the rental vehicle is simple and rustic, simple instructions for use are enough to prevent any mishandling. If the rental vehicle is sophisticated, for example if it is a helicopter, it seems insufficient to fully trust the occasional pilot. Indeed, it is possible to operate a helicopter in abnormal or out of range conditions and thus cause damage or wear of very expensive parts without such damage or wear being detectable when the rented device is returned.
  • a device of the "black box” type specially designed to be mounted on a helicopter and which does not use a recording system by magnetic tape but by loading digitized data into a logic circuit forming memory.
  • This device is used to indicate to the pilot, during the flight, any exceedance of a controlled parameter, compared to a set value, and can also be used, after the flight, to restore the data recorded during the flight, for all useful purposes .
  • the controls allowing to control the operation of this device are included in the device itself and are therefore accessible by any person, in particular by the pilot of the helicopter.
  • the pilot is a person who hired the machine for a short period, it is not possible to use such a device for the following reasons: - first, the owner of the machine will never be sure that the pilot has not intervened in the operation of the aircraft; - then, the pilot having taken the rental vehicle will not be certain that the parameter values recorded in this device are well representative of the real parameters as read on the corresponding measuring instruments present on the instrument panel .
  • the present invention aims to overcome the drawbacks mentioned above and to provide certain particularly useful advantages, inter alia, in the case of the use of a fleet of locomotion machines intended for rental.
  • the invention therefore relates to a device for controlling the use of a locomotion machine.
  • this control device is characterized in that it comprises a first device, hereinafter called a recorder, intended to be placed on board the locomotion vehicle and comprising a programmable logic circuit, at minus an analog-digital converter circuit whose input is connected to the terminals of a measuring instrument present on the instrument panel and a logic memory circuit intended to record at determined times the output value (s) of the or encoder circuits and a second device, hereinafter called a reader, intended to be kept by the operator of the machine and to be temporarily connected to the recording device, this reader comprising a second programmable logic circuit.
  • a recorder intended to be placed on board the locomotion vehicle and comprising a programmable logic circuit, at minus an analog-digital converter circuit whose input is connected to the terminals of a measuring instrument present on the instrument panel and a logic memory circuit intended to record at determined times the output value (s) of the or encoder circuits
  • a second device hereinafter called a reader, intended to be kept by the operator of the machine and
  • the first and second programmable logic circuits are programmed to exchange binary signals via the electrical link connecting the two devices so that, each time the two devices are connected, the reader begins by comparing a first code memorized permanently in the recorder with a second code permanently stored in the reader and authorizes the continuation of exchange of signals with the recorder only if the first and the second code are identical, then, if so, the reader enters the value or values recorded in the memory circuit of the recorder and transmits this or these values to an editing system intended to be read by the operator of the machine.
  • the first second programmable circuits are also programmed so that, when connecting the two devices, after having started the locomotion machine so that the instrument measurement controlled by the device displays a non-zero value, the second programmable logic circuit receives, via an appropriate control device, a numerical value manually entered into the control device by the operator of the machine, this value being identical to that indicated by the controlled measuring instrument, the first programmable logic circuit then captures the digital value that the converter circuit connected to this same measuring instrument outputs, calculates a coefficient corresponding to the ratio of the digital value coming from the control device on the digital value delivered by the corresponding converter circuit and keeps at the same permanently store this coefficient and so that, during a subsequent connection of the two devices, the first programmable logic circuit captures the stored value (s) and multiplies them by the corresponding coefficient kept in memory, the result constituting the value (s) intended to be effectively transmitted to the editing system intended to be read by the operator of the machine.
  • the invention is based on the fact that it appeared to the applicant that it is both simple and very effective to design an assembly formed by two connectable devices and each comprising a circuit programmable logic, for example a microprocessor.
  • One of the devices is intended for recording data in the machine in operation and its microprocessor is essentially used to manage the acquisition of data and their calibration, while the other device also has a microprocessor allowing the reading of the recorded data, after the return of the machine, and their management essentially with a view to checking the good piloting of the machine and its mode of use, for example in order to determine the price of its rental .
  • the recorder comprises several independent encoder circuits intended to be each connected respectively to different instruments for measuring the locomotion machine and in that the first programmable logic circuit establishes and stores in memory independently each coefficient corresponding to each of the measuring instruments thus connected.
  • each measuring instrument between each measuring instrument and the corresponding converter circuit, an electronic circuit for adapting impedance or amplifying the electrical signal delivered to the terminals of the measuring instrument and in that each assembly formed by this electronic circuit and the corresponding converter circit is supplied with direct electric current from a DC-DC converter with galvanic isolation between the outputs and the inputs and that the converter circuit is connected to the first logic circuit programmable by means of electrical connections each comprising a component allowing the transmission of electrical signals with galvanic isolation.
  • the first programmable logic circuit is programmed so that it captures at determined time intervals the digital values corresponding to one of the measuring instruments controlled and stores in memory these values and the corresponding times delivered by a clock.
  • the first programmable logic circuit is programmed so that it captures at determined time intervals the digital values corresponding to one of the measuring instruments controlled and stores in memory only the maximum or minimum value encountered.
  • its recorder comprises at least two encoder circuits, one of which is intended to be connected to the measuring instrument indicating the value of the torque at the level of the rotor or the value of the incidence of the blades of the helicopter and the other of which is intended to be connected to the measuring instrument indicating the value of the temperature of the exhaust gases from the nozzle (temperature commonly called T4) and in that the first programmable logic circuit determines and stores the time of the effective flight of the helicopter by comparison of the value of the torque of the rotor with respect to a predetermined value.
  • a sensor 2 measuring the engine torque at the rotor and a sensor 3 measuring the temperature of the gases leaving the nozzle, called commonly temperature T4, of the propulsion engine.
  • the sensor 2 is connected, by an electrical link 4, to the corresponding measuring instrument 5 present on the dashboard of the helicopter.
  • This sensor 2 is constituted for example by a strain gauge and the measuring instrument 5 which corresponds to it consists of a galvanometer whose needle directly indicates the value of the torque.
  • the sensor 3 is connected, by an electrical link 6, to the corresponding measuring instrument 7 present on the dashboard of the helicopter.
  • This sensor is constituted for example by a thermocouple and the measuring instrument 7 which corresponds to it consists of a galvanometer whose needle directly indicates the value of the temperature T4.
  • the control device consists of a first device 8, called a recorder, the lines of which can be distinguished by dashed lines and which groups together the electronic components present within this trace, and a second device 9 , called reader, whose lines are distinguished in broken lines and which groups together the electronic components present within this layout.
  • the recorder 8 has two inputs 10, 11 adapted to respectively receive the electrical signal at the terminals of the instrument 5, via an electrical connection 12, and the electrical signal at the terminals of the instrument 7, via an electrical connection 13.
  • L one of the terminals of input 10 is connected to the input - of an operational amplifier 14 via a resistor 15.
  • the other terminal of input 10 is connected to input + of the same operational amplifier 14.
  • the input - and output 16 of the amplifier 14 are connected by a resistor 17.
  • the voltage gain of such an amplifier 14 is therefore substantially equal, in absolute value, to the ratio of the resistor 17 on the resistor 15.
  • the output 16 is connected to the analog input of an analog-digital converter 18 whose digital output 19 attacks an opto-electronic component, known per se, intended to transmit the logic signal present at 19 to its output 21, 22 all by ensuring galvanic isolation between its input 19 and its output 21, 22.
  • the recorder 8 is supplied with direct electric current coming either from a source 23 of the helicopter 1 when the recorder 8 is in the helicopter 1, either from an independent battery when the recorder 8 is separated from the helicopter 1, the circuits of the recorder 8 remaining maintained at all times under a correct supply voltage so that the memories they contain are not erased.
  • the supply of electric current to the amplifier 14 and the converter 18 is not done directly from the sources 23 or 24, but is done via a DC-DC converter 25, known per se, and whose inputs connected to electrical sources 23 or 24 are galvanically isolated from the outputs used to supply circuits 14 and 18.
  • the second input 11 corresponding to the second measuring instrument 7 is connected in the same way as the input 10 to another set of electronic circuits designed identically to the set described above and whose different components (amplifier, resistors, converter continuous-continuous and analog-digital converter) respectively have the same references differentiated by a "premium" in the index.
  • the recorder 8 also includes a first programmable logic circuit constituted by a microprocessor 26 receiving as inputs the logic signals coming from the components 20 and 20 ′ and connected by a suitable bus to a memory of the RAM 27 type (random access memory).
  • a first programmable logic circuit constituted by a microprocessor 26 receiving as inputs the logic signals coming from the components 20 and 20 ′ and connected by a suitable bus to a memory of the RAM 27 type (random access memory).
  • Circuits 26 and 27 are directly supplied with current electric from sources 23 or 24.
  • the control device further comprises a second device 9, called a reader, separate from the recorder 8 but connectable to the latter via appropriate connections 28.
  • the reader 9 essentially comprises a second logic circuit programmable constituted by a microprocessor 29.
  • the reader 9 also comprises a control device constituted by a set of coding wheels 30 each output of which represents the binary code of the digit which it displays, all the outputs of the coding wheels 30 being connected by appropriate connections 31 to the microprocessor 29.
  • the reader also includes a validation button 32 connected to the microprocessor and an editing system, such as a printer 33, intended to be read by the operator.
  • the microprocessors 26 and 29 are arranged so that they can be programmed, in a manner known per se, to perform the logical and arithmetic operations corresponding to the operating process of the recorder 8 and of the reader 9 as described above in the paragraphs describing the different features of the invention. It can however be added that it is in the RAM circuit 27 that the various recorded data are stored, essentially constituted by the digital values resulting from the coding of the values measured on the instruments 5 and 7, the time and dates of these measurements as well as by the said coefficients relating to each instrument 5 and 7.
  • the operator can calibrate or recalibrate this or these parameters which are precisely taken into account by the recorder 8.
  • the pilot starts the machine in such a way that the on-board instrument indicates a value of the parameter in question approaching the maximum permitted value.
  • the operator displays on the encoder wheels 33 of reader 9 this value of the parameter and, when the on-board instrument indicates exactly the same value as that displayed on reader 9, the operator validates the calibration by actuating the validation button 32, and this in the presence of the occasional pilot.
  • This process has the double advantage of making the occasional pilot clearly understand what the instructions are to be observed and of obtaining the consensus of the operator and the occasional pilot regarding the calibration of the control device according to the invention.
  • the operator can also edit, immediately after calibration, a value read by the recorder 8 and which is immediately delivered by the editing system 33 (for example a small printer) of the reader 9. The pilot can then note the accuracy of the measurement made by the control device. It can also be noted that this calibration method, which is one of the characteristics of our invention, makes it possible to dispense with very precise and very stable measurement systems, since all the errors of the electrical signal conversion system are generally corrected by said coefficient resulting from the calibration process and since this coefficient is stored in the form of a binary number, therefore unalterable.
  • control device The presence of a microprocessor in each of the two devices, recorder and reader, constituting the control device also constitutes a great advantage to be able to allow the inviolability of the recorded or transmitted information since it is very easy with programmable circuits to compare secret codes and that it is also easy to subsequently modify the program performing this code check, if necessary, for example if the code or the code verification process are discovered.
  • the invention is not limited to the embodiment which has just been described but encompasses all the variants.
