Description

A SYSTEM AND METHOD FOR TRANSFERRING DATA AND CONTROL
SIGNALS BETWEEN A TAXIMETER AND A REMOTE LOCATION
Field of the Invention The present invention relates to a taximeter and in particular to a computer controlled system and method for transferring data and control signals between a taximeter and a remote location.
Background of the Invention A taxi company keeps records of numbers of fares, fares collected, and dates, times and fare locations for each taxi in its fleet. A taximeter is installed in each taxi to record some of this information. At the end of a fare, the information recorded on 15 the taximeter is transcribed onto a paper recording receipt. At the end of the shift, the fare data obtained during the shift, recorded on dozens of paper recording receipts, has to be uploaded to a processing and storage device generally located in the dispatch office. The most common way to upload fare data is for the operator to take the paper recording slips to the dispatch office. There, a data entry clerk will manually input the 2o information into a computer for sorting, processing and storage. This method is time consuming and can be disruptive since a large number of operators may want to remit their receipts at the end of every shift. This method is also prone to mistakes by the data clerk due to misreading the operator's handwriting, lost receipts or keyboarding errors. This method is also vulnerable to tampering and corruption by unscrupulous 25 operators because information recorded on the receipts can be readily falsified.

In their travels, taxi operators may have to stop at a toll station and pay a cash toll. This is a very disruptive process for the operator and the client. The toll must be added to the client's fare, recorded on a receipt and segregated during data entry and processing. This process is vulnerable to fraud by unscrupulous operators who can falsify the toll fee amount. Processing toll fees adds greatly to the administrative burden on the taxi company. Furthermore, modern highways and airports are also being equipped with automatic toll recording devices.
1o Proposals to improve taximeters are well documented, for example, Canadian Patent Application Number 2,139,897 filed on January 10, 1995 by Claude Richard teaches a taximeter which can be disabled in the event of unauthorized modifications to the taximeter by an operator. Richard does not address the problems relating to transferring fare data from the taximeter to a processing and storage device at the end of each shift. Automated toll collection systems have also been proposed. For example, Canadian Patent Application Number 2,194,826 filed by Kiochiro Fujimoto on January 10, 1997 describes a toll collection system that automatically collects a toll from every passing vehicle and then prepares toll charge data related to that vehicle.
However, Fujimoto does not teach how an automatic toll collection system can be 2o adapted to charge a toll fee directly to a taximeter. Generally, prior art taximeters cannot cope with the volume of fare data generated by a modern taxi company or efficiently cope with toll fees that must be charged to individual clients.
There is therefore a need for a system and method that addresses the above shortcomings and provides swift and efficient taxi fare data collection and processing, is able to easily charge toll fees directly to the client and reduces the opportunities for fraud by unscrupulous operators.
Summary of the Invention An object of the present invention is to provide a system and method which improves the processing of large amounts of taxi fare data from a plurality of taxicabs 1o in a large taxi operation, facilitates the collection of toll fees and permits their direct charge to the client and reduces the vulnerability of the taximeter and fare data processing and collection system to fraud.
In accordance with one aspect of the present invention there is provided a 15 system for transferring data and control signals between a taximeter and a remote location comprising: a taximeter mounted in a taxicab for collecting and digitally storing fare data; means for remotely controlling specific functions of the taximeter;
means for remotely collecting, storing and processing fare data from a taximeter;
means for identifying the taximeter; and, means for establishing two way 2o communications between the taximeter and the remote controlling means.
In one embodiment of the present invention the taximeter has an input/output device for transferring stored digital data to and receiving instructions from a remote location. The input/output device may be a RS232 serial port connected to a modem.

In another aspect of the present invention, the system is controlled by a remotely located computer. The remotely located computer receives fare data from the taximeter, stores and processes it. The computer may also command the taximeter to perform specific functions such as compare the fare structure and calibration data currently stored in the taximeter with data stored in the controlling computer.
In a further embodiment of the invention, fare data security is enhanced by electronically tagging the taximeter with a unique identifying serial number that can be queried by the controlling computer. This security feature can be further enhanced 1o by encrypting the serial number to prevent copying of the serial number for fraudulent purposes.
In another aspect of the invention the taximeter and the controlling computer establish two-way communications with each other by using a first and second 15 modem. The first modem is serially connected to the taximeter and the second modem is serially connected to the remote-controlling computer. The modems can be IRDA serial links or low power, spread spectrum radio modems. The modems are capable of wireless transmission over short distances in all environmental conditions.
Typically, this distance is less than ten (10) meters.
2o In yet another embodiment of the present invention the remote controlling computer can disable the taximeter by issuing a disabling command if preconditions are met. For example, if the fare data stored in the taximeter were not downloaded to the controlling computer within a specified period of time, at the next occasion when the taximeter communicates with the controlling computer the disabling command would be issued.
In still another embodiment of the present invention the taximeter is able to disable itself if certain preconditions exist. For example, if the taximeter has not been 1o connected to the controlling computer within a predetermined period of time, the taximeter would automatically disable itself.
In a further aspect of the present invention the taximeter can be electronically interrogated by governing authorities with a compatible modem to verify rate settings.
In still another aspect of the present invention, when the taximeter mechanical seal has been opened by authorized personnel to change rate or calibration data, the remote controlling computer can upload the collected data to the taximeter.
2o In a further embodiment of the present invention, a portable or laptop computer equipped with a compatible modem can be taken to a taxi and taxi fare data unloaded from the taximeter. The portable computer can then transfer the downloaded data to the remote-controlling computer.

In still another aspect of the present invention, the taximeter is capable of electronically identifying itself to a highway or airport toll station and receive a signal from the toll station that instructs the taximeter to automatically add the toll fee to the taxi fare. The toll fee can then be segregated from the fare data by the remote-controlling computer. Alternatively, the taximeter is capable of sending a signal to a highway or airport toll station receiving means to instruct the toll station controlling computer to deduct the toll fee from a prepaid account registered to the taxi company and identified by the taximeter identification number.
1o In a further another embodiment of the present invention, the taximeter records all of the fare and toll data entered in an operator's shift. The operator then brings the first modem serially connected to the taximeter in communication with a second modem serially connected to the remote controlling computer and located at a 15 data downloading station. The second modem at the downloading station is fixed to a supporting structure. Once communication between the taximeter and the controlling computer is established, the controlling computer instructs the taximeter to download the serial number, the fare and toll data that is subsequently processed and stored by the control computer.
The present invention provides for a number of advantages by: simplifying the transfer of fare and toll fee data from the taximeter to the processing computer;
recording toll fees and directly charging those to the client; and, by reducing the vulnerability of the taximeter and data processing system to errors and fraud.

Brief Description of the Drawings The present invention will be further understood from the following description with reference to the drawings in which:
