Definitions

  • the invention comes within the technical sector of automation, more specifically that relating to the technical inspection of vehicles and the checking of tachychronometric devices (taximeters).
  • the calculation of the price to charge for a taxi ride is determined by two factors: the time during which the taxi has not exceeded a certain speed (hauling speed) and the distance traveled when the speed is greater than the hauling speed. This price is calculated automatically by the tachychronometric devices or taximeters fitted to taxis.
  • Vehicles intended for taxi services must necessarily pass an annual vehicle technical inspection.
  • This technical inspection checks the precision in the marking of taximeters (among other matters).
  • the measurement provided by the taxi's taximeter is compared with the measurement provided by a certain system known as the standard taximeter. If the measurement read in the taximeter exceeds a maximum or fails to reach a minimum (both values being established in percentage terms in the existing legislation), then the taximeter is not valid and has to be repaired or replaced. If the measurement lies between the legal margins, the taximeter is sealed in the vehicle technical inspection centre.
  • the annual check on taximeters is usually carried out in January, since it is at the end of December of each year when the taxi tariffs are published for the following year; so, at the beginning of January, the owner of the taxi goes to a garage so that they can adapt the taximeter to the new tariffs and he then immediately tries to pass the appropriate technical inspection since by law he cannot provide a service until he has passed that inspection.
  • a city such as Madrid there are about 13,000 taximeters that need to be "sealed" within the shortest possible time.
  • the sources of error for calculating the price charged for a taxi service are:
  • the apparatus that is currently used for checking tachychronometric devices or taximeters basically consists of two or more steel rollers between which the drive wheels of the vehicle are located.
  • the rollers are provided with pulse generators (they generate a certain number of pulses per turn of the roller), therefore, knowing the diameter of those rollers and the pulses generated per unit of time (generally one second), it is possible to calculate the speed, determine whether it is greater or lesser than the hauling speed, and as appropriate calculate the distance traveled or the time taken.
  • ABS electronic driving assistance systems
  • ESP electronic switchboard
  • the development is based on the use of NAVSTAR-GPS technologies.
  • the initials GPS identify a set of technologies which, by means of a device (GPS receiver) and an array of satellites in orbit above the earth, make it possible to estimate the position and speed of a mobile telephone on the earth's surface.
  • the measurements that are collected in the GPS receiver are, among others, longitude, latitude, height, speed, number of satellites in use and time. Moreover, information is received on the time the signal takes to reach the receiver from each satellite.
  • the majority of GPS receivers can communicate with digital devices using the protocol NMEA0183.
  • This protocol sends sentences such as the following: $GPRMC, 182023. 0123, A, 4321. 0564, N, 00549. 2310, W, 50. 21. 12, 120206, , , A*7 a
  • a device For a proper check on the precision in the tariffs calculated by a taximeter, a device is needed that provides data in order to calculate the speed at which the taxi is traveling at each moment, the time during which the taxi travels at a speed below the hauling speed and the distance it travels at a speed greater than the hauling speed.
  • This device has to have the characteristic of being portable, since the objective is to locate it in the taxi and conduct the check on the taximeter in a situation that is as close as possible to a real taxi ride.
  • the present invention makes use of GPS technology, which permits access to data on position, speed and time.
  • This data will be processed in real time by a digital device programmed to calculate the pertinent tariffs. It is also possible to gather the necessary data for carrying out a trace of the check on the taximeter. This data can be downloaded into a personal computer for being stored.
  • the present invention makes reference to a novel device that permits taximeters to be checked. Unlike the devices that are currently used, the checking is carried out in a real situation (with the taxi following a real route) and using NAVSTAR-GPS technology (most current systems use a roller system).
  • the device is made up of a printed circuit board containing: a GPS receiver, an LCD panel or screen, a keypad, a microprocessor, a communications interface and a battery. There will also be a GPS antenna for improving the quality of the reception of the signal from the satellites,
  • the interconnections of the different electronic devices are shown diagrammatically in figure 1 .
  • the application of the invention is immediate, given the advantages it presents compared to other systems and the speed of setting-up and use in those companies that carry out checking services for taximeters, which are currently those that carry out vehicle technical inspections.
  • FIG. 1 shows a diagram of the system to patent.
  • the GPS receiver (1) is connected to the antenna (2).
  • the processor (3) receives data from the receiver (1) in the form of an NMEA0183 sentence, on the basis of which it obtains data on position, speed and time, and data relating to the precision of the measurement.
  • the kilometer tariff or the hourly tariff is applied. If the speed is below the hauling speed, then the hourly tariff is taken into account, and if the speed is above the hauling speed, then the kilometer tariff is taken into account.
  • the tariff is composed of: the price for getting into the cab plus the part corresponding to the hourly tariff plus the part corresponding to the kilometer tariff.
  • Control of the standard taximeter (the object of this patent) is carried out by means of the keypad (5), from which the start of the test, the end of the test or the start of a new test can all be selected.
  • the LCD panel or screen (4) is sent the calculated (real) tariff data and that of the maximum and minimum tariffs permitted according to legislation, along with data on the precision of the information gathered from the satellites.
  • All the gathered data can be stored in a personal computer by connecting the standard taximeter to the personal computer by means of the communications interface (6).
  • the data on the price of getting into the cab, cost of a kilometer in the kilometer tariff and cost of the hour of waiting in the hourly tariff are transmitted to the system from a personal computer using this same communications interface.
  • the whole system is electrically fed by the battery (7).
  • figure 2 can be seen the external appearance that the system has when it has been placed in a box made of a resistant material (8) which permits access to the keypad (9), to the LCD screen (10), to the communications port (11), to the connector for charging the battery (12) and to the connector for the antenna (13).
  • the GPS receiver, the microprocessor, the battery and the communications interface, along with the printed circuit board where they are located would be contained inside a box made of a resistant material.
  • the box has to have the necessary openings for providing access to the keypad and to the LCD screen. It must in turn permit access to the connection plug of the antenna to the GPS receiver, to the communications interface and to a socket for charging the battery.
  • the external appearance of such a box would be similar to that shown in Figure 2 .
  • a prototype has been developed in which the FV-M5 GPS receiver and an antenna have been used, both from the company San Jose Navigation, along with an ATMEGA2561 microprocessor from the firm ATMEL, an MC 1604C-SYL LCD panel, a membrane keypad with 25 keys, an RS232C connections port and a lithium ion battery.
  • the printed circuit board is own design, as is the software that is run in the microprocessor.
  • the system is contained inside a plastic box having the characteristics described above.
