Definitions

  • the present invention relates to an hour meter for explosion engines. It finds an application whenever we want to measure the operating time of an internal combustion engine, regardless of the vehicle or the device on which this engine is mounted: outboard, tiller, generator, generator, motor pump, light aircraft, automobile, etc. This measurement of the operating time is necessary to determine the expediency of carrying out checks, adjustments, oil changes, etc. or to bill device rentals made over time.
  • the object of the present invention is precisely to propose an apparatus which overcomes these drawbacks.
  • the invention provides an hour meter for explosion engines which is characterized by the fact that it comprises: - an antenna, - a shaping circuit having an input connected to the antenna, - A microprocessor having an input to restore the operating condition connected to the output of the shaping circuit, this microprocessor being able to perform a time count, this microprocessor having at least one memory for storing the accumulation of the result of this counting with the cumulative result of previous counts, - a time base connected to the microprocessor, a display means connected to the microprocessor for displaying the cumulative result stored in the memory, - a power supply stack.
  • the shaping circuit can be a logic circuit.
  • the counter of the invention can include a manual control means of the display, connected to the microprocessor.
  • the display means comprises a liquid crystal display screen.
  • the other known means of display are not excluded (light-emitting diodes, plasma, etc.).
  • the microprocessor may include a second memory for storing the result of a partial count.
  • the counter is then provided with a manual means for resetting the content of this second memory to zero.
  • all of the counter means are molded from a block of impervious material, for example a polymer.
  • FIG. 1 represents the block diagram of the counter of the invention
  • FIG. 2 illustrates a particular embodiment of this counter
  • FIG. 3 shows the external appearance of a counter according to the invention
  • - Figure 4 shows the appearance of the display screen in various situations.
  • the device shown in FIG. 1 comprises an antenna 10 which, in the illustrated variant, is wound around a ferrite core 11, a shaping circuit 12 having an input 13 and an output 14, the input 13 being connected to the antenna 10.
  • This circuit 12 is capable of delivering a signal suitable, for example a logic signal, on the output 14 when it receives on its input 13 a signal corresponding to an electrical noise emitted by an engine 9 comprising spark plugs 8.
  • the device represented also comprises a microprocessor 15 having three inputs 16, 17 and 18 and an output 19.
  • Input 16 is an input to restore operating status (in English terminology "reset").
  • a time base 20, constituted for example by a quartz or RC oscillator, is connected to the input 18 of the microprocessor 15.
  • a push button 32 is connected to the input 17 of the microprocessor 15.
  • the device also comprises a display means 24 connected to the output 19 of the microprocessor 15.
  • This means comprises for example a display control circuit 26 and a display screen 28, which is, for example, of the crystal type liquids and seven segments.
  • this hour meter The operation of this hour meter is as follows.
  • the electromagnetic parasites generated by the spark plug 8 of the explosion engine 9 are picked up by the antenna 10; the circuit 12 generates a signal of appropriate shape which is applied to the input 16 ("reset") of the microprocessor 15.
  • the latter which is normally in a standby state, is awakened by the signal applied to the input "
  • the result of this count can be displayed directly on the display 28 or displayed on command by pressing the push button 32.
  • the time counted, during each start-up, is accumulated in a memory, which is an integral part of the microprocessor and is kept energized. By pressing button 32, the cumulative running time of the engine with which the counter is associated is therefore displayed.
  • the battery 30 can be a lithium battery whose lifespan is several thousand hours.
  • the resonator 20 can be a ceramic or quartz resonator operating for example at 262,144 Hz or at 32,768 Hz.
  • the antenna can also consist of a conductive track deposited on a printed circuit or on an insulating support, for example made of mylar.
  • FIG. 2 represents a particular embodiment of an hour meter according to the invention.
  • Figure 2 there are elements which have already been shown in Figure 1 and which, for this reason, have the same references.
  • Figure 2 shows the connections to be made with the microprocessor which is, in the illustrated case, the PD 7754 or 64 type microprocessor marketed by the company NEC. You can find, on the commercial sheet relating to this product, all the characteristics of the microprocessor.
  • the liquid crystal display can be of the LC 241440 type sold by the company RTC. It can be controlled by a control circuit of the PCF 2112 type sold by the company RTC.
  • the shaping circuit 12 is a logic circuit which includes four NAND type gates ("NAND" in English terminology) referenced P1, P2, P3 and P4.
  • the doors P1 and P2 are mounted on an RS flip-flop. This flip-flop changes state under the control of signals coming either from the antenna by connection a or from the microprocessor by connection b .
  • gate P4 reverses the logic signal delivered by gate P3.
  • the action on the push button 32 causes the appearance of a "0" on one of the inputs of the door P3, where a "0" is applied on the other input coming from the scale; then P3 delivers a "1” and P4 a "0", which triggers the microprocessor. Furthermore, the output of the flip-flop is connected by a connection c to the microprocessor which selects either the display of the counted time if the logical state of the connection c is "1", or the counting if the state of the connection is "0".
  • This logic shaping circuit can optionally be integrated into the microprocessor.
  • shaping means could be used, such as for example a rectifying diode and a storage capacitor, the storage voltage maintained during the arrival of the parasites determining the duration of the counting.
  • FIG. 3 shows an exemplary embodiment of a counter according to the invention. All the means described in FIG. 2 are molded from a material 40 which is, for example, a flexible anti-shock and anti-vibration polymer which guarantees total sealing up to 10 meters deep and resistance to the atmosphere. Marine.
  • FIG. 3 also shows the display screen 28 and the push button 32 on which the operator can act to cause the display of the number of hours of engine operation.
  • the device illustrated also comprises a fixing lug 42 and it may have a rear face coated with an adhesive layer 43.
  • the fixing of such an appliance on a motor is therefore immediate.
  • the display can be done by four digits with a height of 6.8 millimeters.
  • the dimensions of such a case can be 70x50x25 mm.
  • the autonomy of the counter of the invention is considerable and can exceed several thousand hours.
