17、*50148 95 = 3404583 0167778 355 Page 4 EN 50148 : 1995 ELECTRONIC TAXIMETERS 1. Scope This Standard applies to electronic taximeters, hereinafter referred to by the general term taxime- ters, to be installed on public hire vehicles (taxis or cabs) which, with the aid of electronic devices, calculate
18、 and indicate the amount to be paid by the passenger of the taxi. This standard does not apply to taximeters being remotely controlled by external intelligence as far as it concerns the functions described in this standard. This standard does not deal with performance requirements of the taximeter a
19、fter installation or with the installation itself. 2. Definitions For the purpose of this Standard the following definitions apply. 2.1. Electronic taximeters Electronic taximeters are instruments normally installed in taxis which, mainly by means of electronic components, calculate and display the
20、fare to be paid for the use of the taxi, on the basis of distance travelled and duration of the hiring. 2.2. Device constant k of the taximeter The device constant k of the taximeter is a value giving the number of the pulses which the instrument must receive in order to correctly indicate a distanc
21、e travelled of 1 kilometre. According to the construction of the instrument, the device constant k may be adjustable. 2.3. Vehicle constant w The vehicle constant w is a value giving the number of pulses supplied to the taximeter and appearing on the connecting component of the vehicle for a distanc
22、e travelled of 1 kilometre. The constant w is expressed in pulses per kilometre (km-). 2.4. Totalizers The totalizers are formed by counting registers, which accumulate values for purposes other than the transaction between driver and customer. 2.5. Initial hire fee The initial hire fee is a fixed a
23、mount, charged to the passenger, regardless of the time or distance of the journey. 2.6. Initial distance The distance which can be travelled according to the tariff for the initial hire fee, considering distance-counting only. CENELEC EN*50148 75 3404583 01167777 291 Page 5 EN 50148 : 1995 2.7. Ini
24、tial time The period during which the taxi can be used for the initial hire fee, considering time-counting only. 2.8. Time-counting Time-counting is the calculation mode in which the fare increases in proportion to the duration of the hiring. 2.9. Distance-counting Distance-counting is the calculati
25、on mode in which the fare increases in proportion to the distance travelled. 2.10. Time-distance counting Time-distance counting is the calculation mode in which two additional components of the fare increase concurrently, one in proportion to the duration of the hiring and the other in proportion t
26、o the distance travelled. 2.1 1, Single system calculation Single system calculation calculates the fare using either time-counting or distance-counting (see 4.1.1. under a). 2.12. Double system calculation Double system calculation calculates the fare using time-distance counting. 2.1 3. The maximu
27、m value of the error allowed. Maximum permissible error (MPE) 2.14. Distance measuring signal The signal supplied by the taximeter to the calculating device, in proportion to the distance travelled. 2.15. Time measuring signal The signal supplied by the taximeter to the calculating device, in propor
28、tion to the duration of the hiring. 2.16. Reference number of pulses The theoretical number of pulses from the distance- and/or time measuring signal, which can be calculated using the tariff data and the device constant k, which should lead to a certain change in the price indication. Page 6 EN 501
29、48 : 1995 2.17. Tariff A set of tariff values which will be operative in the taximeter in a specified tariff position. 2.18. Tariff values The values from which the taximeter calculates the fare. 2.1 9. Distance tariff value The tariff value expressed as an amount of money for a given distance. 2.20
30、. Time tariff value The tariff value expressed as an amount of money for a given period of time. 2.21. Tariff position A position to which the taximeter can be adjusted in the operating position OCCUPIED. Pre- adjustment may be possible in the operating position FOR HIRE. 2.22. Tariff regulation A r
31、egulation, establishing which tariffs and supplements are to be applied under specified conditions. 2.23. Supplement An amount of money charged to the passenger for an extra service, which is not the result of the measurement performed by the taximeter. 2.24. Calculating device The part of the taxim
32、eter by which the measured distance and the measured time are converted into the fare, using the selected tariff-values. 2.25. Adjustment device The part of the calculating device, by which the device constant can be adjusted to the vehicle constan t. 2.26. Securing Securing includes all measures wh
33、ich will make unauthonsed changes to the taximeter improbable and/or detectawe because the knowledge, tools or parts necessary to perfomi or conceal such changes are not expected to be available to an unauthonsed person.

34、Sealing includes those securing measures which can only be applied by persons authorised to apply a legally protected sealing mark. 3. Unit of measurement The distance and time shall be presented in S.I. units. The fare and any supplement shall be displayed in legal monetary units of the country whe
35、re the taximeter will be used. In countries where Imperial units are legal, these units may be used. 4. Technical characteristics 4.1. Calculating device 4.1.1. Calculation methods The calculation of the fare can ,e camed out by one of to the following met,.ods: a) By time-counting or distance-count
36、ing. The change of time-counting to distance-counting shall take place when the speed of the car is such that the distance-counting becomes more important than the time-counting, taking into account the applied tariff values. This speed is determined by the value resulting from the division of the t
37、ime-tariff value by the distance tariff-value. b) By time-distance counting. The taximeter shall be constructed in such a way that both calculation methods are possible. It must be possible to secure this switch option. 4.1.2. Price indication Time-counting andior distance-counting shall be activate
38、d when the taximeter is switched to the operating position OCCUPIED. At this moment the initial hire fee shall be indicated. The first change in price indication shall take place after initial distance or initial time or combination of time and distance. The initial distance and the initial time are
39、 specified in the applied tariff. The subsequent changes in price indication shall take place afier a certain time or distance has elapsed. For double system calculation a subsequent change in price indication shall take place after a combination of time elapsed and distance travelled in accordance
40、with the selected tariff. This also applies in case of single system calculation if a change from time-counting to distance-counting or vice versa occurs. In this case no rounding related to the monetary step is allowed. 4.1.3. Device constant The device constant k shall not be lower than 500 pulses
41、 per kilometre and it shall be possible to adjust it to the vehicle constant w with such an accuracy that the maximum permissible error specified in subclause 7.3. is not exceeded. It shall be possible to display the device constant k on the taximeter as a readily accessible decimal number. CENELEC
42、EN*50148 95 3404583 O367782 88b W Page 8 EN 50148 : 1995 4.1.4. Tariff positions It shall be possible to inhibit access to unused tariff positions by securing measures. 4.2. Operating device The taximeter is switched on and can be brought into the operating positions specified below by the operating
43、 device. This operating device may, for example, consist of specific keys and switches for specific functions. If the vehicle is driven at a speed exceeding 5 km/h, the taximeter shall prevent a changeover from the FOR HIRE position to the OCCUPIED position and from the OCCUPIED position to the FARE
44、 position. 4.2.1. Operating position “FOR HIRE“ In this position: a) the fare indication and the supplement indication shall be cleared or reset to zero; b) it may be possible to pre-adjust to a tariff position. In this position it must be possible to display the following parameters: a) all indicat
45、ing elements; b) the contents of totalizers; c) the constant k expressed in pulses per kilometre (km“); d) the tariff data; e) the contents of the electronic sealing counters according to clause 8. The parameters above shall not be displayed when the vehicle is moving at a speed above 5 kmih, if the
46、 fare indicating elements are used. Other indications are permitted provided that: a) they cannot be interpreted as fare or supplement indication; b) their use can be inhibited by securing measures. 4.2.2. Operating position “OCCUPIED“. The appropriate tariff shall be activated either in the operati
47、ng position “OCCUPIED“ or as part of the process of switching from the operating position “FOR HIRE“ to the operating position “OCCUPIED“. Automatic selection of a tariff may be performed according to the tariff regulation in force. 4.2.3. Operating position “FARE“ Starting from the operating positi
48、on FARE, it shall be possible to set the taximeter to the operating position FOR HIRE. It may also be possible to manually set the taximeter back directly to the operating position OCCUPIED, provided that securable means are available to prevent it when not permitted.
