DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling the output of information on a fare to which an additional fare system is applied by applying an additional system such as a discount or a surcharge to a normal fare calculated by a taxi meter. The present invention relates to an external fee display device suitable for implementation and used in connection with a taxi meter, and a device for supplying operating power to a taxi meter system including the external fee display device and the taxi meter.

[0002]

2. Description of the Related Art In recent years, in the taxi industry, if the time required for the ride distance is lower than a certain ratio,
There has been a movement to introduce new discount premiums such as discounting the fare at a fixed rate, and to improve the service in terms of fare for passengers.

As a taxi meter capable of displaying a fare to which such a new discount premium system is applied, for example, Japanese Utility Model Application No. 5-5836 by the prior application of the present applicant.
There is a taxi meter of No. However, in this taxi meter, the tariff status of the taxi meter indicates
In the state of extra tariff, the normal fare before discount is displayed,
When switching the tariff state from these tariffs to the payment tariff, by operating the discount tariff button of the taxi meter together, the discounted fare is displayed for the first time. It is not possible to check the discounted fare in real time over the entirety of the business tariff, including the tariff tariff and the 30% tariff.

In order to display the fare to which the discount premium system is applied by a taxi meter alone, it is necessary to remodel an existing taxi meter or replace it with a new taxi meter. Therefore, it is conceivable to construct a taxi meter system by externally attaching a toll display device to an existing taxi meter, and to display the fare to which the discount premium system is applied by using the toll display device.

As a conventional taxi meter system,
For example, Japanese Utility Model Application Laid-Open No. 56-19876 and Japanese Utility Model Application Laid-Open No.
There is a taxi meter disclosed in Japanese Patent No. 9877. These taxi meters have a main body and an external fare display device, and are configured to display the fare on each of the fare indicators.

[0006]

However, these taxi meters merely display the fare calculated by the main body on the fare display sections of both the main body and the fare display device. There was a problem that the applied fare could not be displayed. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a first object of the present invention is to apply a surcharge system to which a surcharge system such as a discount surcharge is applied to a normal fare calculated by a taxi meter. And a method of controlling the output of the additional fare system applicable fare information which can be displayed in real time irrespective of the tariff state of the taxi meter, and an external fare display device suitable for implementing the method. .

Further, the external toll display device displays the tariff data indicating the current tariff state output from the taxi meter in real time so that the tariff state changes so that the empty tariff changes to the business tariff in conjunction with the taxi meter. It is necessary to take in. Therefore, the connection of the external charge display device to the taxi meter uses a signal line and an interface dedicated to tariff data transmission, similarly to the connection of the operation information collection device that collects and records the operation information of taxis. Moreover, since the tariff set by the external fee display device is a tariff not found in a taxi meter,
When the operation information collection device and the external charge display device are used together, it is necessary to load the tariff data set by the external charge display device into the operation information collection device in real time. For this reason, it is conceivable to connect the external charge display device and the operation information collection device with a signal line dedicated to the transmission of tariff data, similarly to the connection between the taxi meter and the operation information collection device.

However, with the above-described connection form, a new tariff system is approved and new tariffs are generated with the progress of introduction, so that only one external tariff display device can cope with all new tariffs. In the case where a plurality of external charge display devices are connected to one taxi meter and the number of connection parts such as dedicated signal lines and interfaces, and the number of connection processes for them are reduced, the external charge A problem arises that the number increases according to the number of display devices.

In the above-described connection mode, the type of the new tariff is set in order for the operation information collecting apparatus to identify the contents of the new tariff indicated by the tariff data from the tariff data fetched from the external tariff display device. Must be performed separately for the operation record collection device. Therefore,
In addition to the connection work of the signal line and the interface, a new work such as a tariff type setting work occurs on the operation information collection device side, and the problem that the number of connection processes is further increased occurs.

[0010] The present invention has been made in view of the above circumstances,
A second object of the present invention is to provide an additional fee-based ride which can suppress an increase in the number of peripheral connection parts and connection steps when interposed between a taxi meter and a device such as an operation information collection device. An object of the present invention is to provide an output control method for fee information and an external fee display device.

Further, when the operation information collecting device is connected to a taxi meter, system data is output from the taxi meter to the operation information collecting device every time the taxi meter shifts from a business tariff to an empty vehicle tariff. The information is recorded on a storage medium by an information collecting device. Therefore, when using an external tariff display device together with the taxi meter, every time the taxi meter shifts from the business tariff to the empty tariff, the system data is output from the taxi meter to the external tariff display device. The contents of the index data in the system data are processed according to the tariff set on the external charge display device, and the processed system data is output from the external charge display device to the operation information collection device, and the operation information is output. The data is stored in the storage medium by the collection device.

[0012] Further, the external fee display device may set a tariff system that does not require the calculation of a fare according to the traveling distance of the taxi meter, for example, a tariff such as a charter.
In such a case, the external tariff display device may be used alone as a business tariff while the taxi meter remains empty. In such a case, there is no transition of the tariff state from the taxi meter sales tariff to the empty car tariff, and the taxi meter does not voluntarily output system data. At the time of the empty car tariff, the external charge display device outputs a data request signal to the taxi meter, and in response to this, the system data is output from the taxi meter to the external charge display device.

However, a general taximeter turns off the power when an accessory switch of the vehicle is turned off with an empty vehicle tariff, and updates index data such as the fare, the number of business trips, and the number of times of business. It is configured to enter a sleep state in which operations such as data transmission are not performed. Therefore, for example, as shown in FIG. 14, after the chartered vehicle with the taxi meter set to an empty tariff at the time A and the external tariff display device set to the business tariff for the charter fee returns to the place of departure and after the accessory switch is turned off at the time B, If the external tariff display device is changed from the business tariff to the empty tariff at the time point C, the taxi is turned off at the time point B when the accessory switch is turned off before the time point C at which the external tariff display device outputs the data request signal. The meter is turned off.

For this reason, the external charge display device cannot obtain the taximeter system data at the time point C, and the old system data at the time point A at which the taximeter has changed from the business tariff to the empty tariff is obtained. We have to process the index using it, and the operation information collection device
This causes a problem that the external charge display device cannot receive the correct system data at the time point C when the empty car tariff is used.

The present invention has been made in view of the above circumstances,
A third object of the present invention is to provide a system in which the external charge display device alone becomes the business tariff when the taxi meter is vacant, and when the external charge display device is switched to the empty tariff,
Provided is an output control method of additional fare system-applicable fare information capable of ensuring that a taxi meter can output system data in response to an external request, and a power supply device for a taxi meter system. Is to do.
