Definitions

  • the present invention relates to a method, a device and a programming suitcase to avoid fraud on electronic taximeters comprising a reprogrammable random access memory containing pricing data.
  • the technical sector of the invention is that of the construction of electronic taximeters.
  • the taximeters that is to say the meters which equip the taxis and which display the prices of the races are currently electronic devices comprising a microprocessor which receives measurements of distance traveled by the taxi and time of occupation of the taxi and which calculates the price to pay by multiplying these measurements by unit prices which are recorded in a memory of the taximeter.
  • Electronic taximeters are known in particular comprising a random access memory (RAM) which contains the data necessary for calculating the price of each race, namely the charge tax, the unit prices of supplements and the prices of the duration unit and of the unit of distance traveled.
  • RAM random access memory
  • This random access memory is a memory whose content can be erased and reprogrammed from an external unit comprising a central computing unit (microprocessor), a random access memory and a keyboard contained in a suitcase called a taximeter programming suitcase, which is used under the supervision of an organization responsible for monitoring measuring devices, for example from the Measuring Instruments Service in FRANCE.
  • a central computing unit microprocessor
  • a random access memory and a keyboard contained in a suitcase called a taximeter programming suitcase, which is used under the supervision of an organization responsible for monitoring measuring devices, for example from the Measuring Instruments Service in FRANCE.
  • Taximeters of this type allow fraud. Indeed, a fraudster with a programming suitcase can use it to fraudulently modify the unit prices recorded in the memory of certain taximeters without the knowledge of the Service of Measuring Instruments and thus make customers pay for race prices higher than the regulated prices.
  • the objective of the invention is to avoid fraud by means of a process by which each programming case is equipped with a counter which records the number of taximeter programming carried out using said case and the an identification number of said suitcase is entered in a memory location of said suitcase and the central unit of said programming suitcase is programmed so that it records, in the RAM of each taximeter, during the programming of the latter, said identification number of the suitcase in place of the previously recorded identification number and said serial number entered in said counter and said taximeters are equipped with means making it possible to display or print the identification number and serial number stored in the memory of the taximeter.
  • each programming suitcase includes a counter which records the number of reprogramming of taximeters and a read-only memory containing an identification number of said suitcase and each taximeter comprises, in said random access memory, a space intended to record during each reprogramming, the identification number of the suitcase used and the order number entered in said counter.
  • a programming case according to the invention is of the type comprising a central unit, a non-volatile random access memory, a keyboard which makes it possible to erase the content of said memory and to write new pricing data and means therein. allowing successively to connect said suitcase to a series of electronic taximeters. It is characterized by the fact that it further comprises a counter which records a number of an order equal to the number of taximeters that have been reprogrammed by said suitcase, a read-only memory location in which an identification number of said suitcase is registered and means for transferring into each taximeter, when the latter is reprogrammed , said serial number and said identification number.
  • the invention results in means for detecting the origin of deception consisting in fraudulently using a programming suitcase to modify the pricing data recorded in taximeters in order to make customers pay sums greater than those resulting from the application of a regulated tariff.
  • the means according to the invention make it possible to identify the suitcase which has been used fraudulently and therefore to identify the fraudster and to prevent him from continuing his fraudulent actions.
  • the reference 1 schematically represents an electronic taximeter which comprises, in particular, a luminous display 2, a central unit 3 composed of a microprocessor, a main memory and a read-only memory containing the program of operations, a non-volatile random access memory 4, in which pricing data are recorded, that is to say the unit prices necessary for calculating the price of the trip and an interface unit 5 which is connected to a distance sensor 6 which is part of the vehicle .
  • the calculation of unit prices also requires a clock 7 which is internal to the taximeter.
  • the interface unit 4 is connected to a socket 8 which can receive a cable coming from a programming case 9.
  • the case 9 comprises a central unit 10 composed of a microprocessor, a main memory and a read-only memory which contains the program for carrying out the data transfer operations.
  • It comprises a non-volatile random access memory 11, into which the pricing data which is to be transferred into a series of taximeters is introduced. It has a unit interface 12 which is connected to a keyboard 13 which makes it possible to erase the pricing data contained in the memory 11 and to write therein a new set of pricing data when these are modified by the regulations in force.
  • the interface unit 12 can be successively connected by a cable 14 to the terminals 8 of a series of taximeters to update the content of the RAM 4 of each of these taximeters by transferring the data of pricing contained in memory 11, the successive operations of this transfer being controlled by the program which is recorded in the read-only memory of the programming case.
  • a device differs from the known devices in that the programming case comprises a memory location in which is recorded an identification code of the case which can for example be a manufacturing serial number.
  • the suitcase 9 includes a counter 15 which records the number of reprogramming operations carried out from a suitcase, that is to say that the number entered in the counter 15 increases by one each time that the suitcase is used to reprogram a taximeter, so that the number entered in the counter 15 is a number which indicates the order in which the reprogramming takes place.
  • the programming case is programmed so that, each time that it is used to reprogram any taximeter, it transfers to a location in the RAM 4 thereof, both the case identification number 9 and the serial number entered in the counter 15 and these data remain recorded in the memory 4 of the taximeter until a new reprogramming of the latter is carried out.
  • the taximeters according to the invention furthermore comprise means making it possible to show on the light display 2 the identification number of the programming case and the serial number which are recorded in memory 4, so that if fraudulent tariff data are recorded in memory 4, it is thus possible to identify the programming case which has been used at this registration and find out by the serial number on how many taximeters this suitcase could have been used fraudulently.
  • each suitcase may be asked to keep a register on which he must record the date and the number of the reprogrammed taximeter opposite each serial number which is read on the counter 15 or on a luminous display.
  • the programming case can be connected to a printer which can print a listing bearing the above indications and which can issue a ticket printed at each reprogramming of a taximeter.
