DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taxi business management system which can maintain the time accuracy managed by a fare adjusting device such as a taxi meter with extremely high accuracy, and a time calibrating method for the fare adjusting device in this system.

[0002]

2. Description of the Related Art Electronic taxi meters, which are currently in the mainstream, have an internal clock, which is used to control whether or not to switch to a premium time and to manage time of business data. In particular, the control of whether or not the extra time is switched is extremely important because it directly affects the fare charged to passengers. In the past, crew members were obliged to manually switch to the extra mode at the extra time, but recently, as the accuracy of the internal clock has improved, the taxi meter has to increase the extra cost. The automatic shift to the mode has come to be accepted, and in many areas, the automatic shift to the premium mode by the taximeter itself has already been implemented. Under such circumstances, the importance of the time managed by the internal clock is increasing. At present, the internal clock built into the taximeter has extremely high accuracy, but it is still necessary to calibrate the internal clock because it is somewhat affected by the temperature change inside the taximeter.

As a method of calibrating the internal clock of a taximeter, a method in which a crew member manually calibrates the time by relying on a time signal sound of a radio is known as the most classical method. However, this method may lead to fraud because the crew can freely change the time. In addition, such manual calibration is also a burden to busy crew members. The present applicant has already proposed many means for solving such a problem, one of which is Jpn. Pat. Appln. KOKAI Hei 3-30928 (utility model registration No. 1911683).
There is. This is a taxi business management system that consists of a fare adjustment device such as a taxi meter installed in a taxi, and a data collection device installed in the garage of a sales office. When transferring to the data collection device using a cable, the current time data managed by the high precision clock in the data collection device is transferred to the fare adjustment device and the current time data in the fare adjustment device is updated. , The details are as follows. The taxi that returns to the business office after one day of running is placed next to the data collection device installed in the garage of the business office or stopped near the data collection device. Then, the cable attached to the data collection device is extended, the connection terminal at the tip of the cable is connected to the data retrieval jack of the fare adjustment device, and the business data in the fare adjustment device is transferred to the data collection device. At this time, the current time data managed by the high precision clock in the data collection device is transferred to the fare adjustment device. By this method, it became possible to completely prevent illegal operation of time data by crew members. Moreover, since the time calibration is automatically performed when the business data is transferred to the data collection device, the labor required for the time calibration is unnecessary and the burden on the crew is reduced.

[0004]

However, since this business management system uses the cable attached to the data collecting device to transfer data, it is necessary to move the vehicle within the reach of the cable when collecting data. It is not suitable when there is not enough garage space, and there is a problem that it is likely to cause confusion especially when a large number of taxis return one after another. In addition, the crew members who finished the business trip paid the sales amount, submitted the operation logbook, returned the crew certificate, etc. at the office in the sales office, etc., and therefore also transferred the data to the data collection device in the office. Although it is clear that the procedure will proceed smoothly, it is not possible to install the data collection device in an office away from the garage because of the cable connection between the fare adjustment device and the data collection device. There is also a problem. The present invention has been made in view of the present situation, and it is not necessary to connect the fare settlement device and the data collection device with a cable, and therefore the data collection device can be installed in an office away from the garage, and It is intended to provide a taxi business management system that can maintain the time accuracy managed by a fare adjustment device mounted in a taxi with extremely high accuracy, and a time calibration method for the fare adjustment device in this system.

The RAM card is a memory card having no CPU. The RAM card is a memory 20 for temporarily storing business data and a clock IC 21 for managing the current time.
And a time calibrating unit 22 that calibrates the current time engraved by the timepiece IC 21 based on time data input from the outside. The memory 20, the timepiece IC 21, and the time calibration unit 22 may be configured by independent elements, but an LSI in which the functions of the timepiece IC 21 and the time calibration unit 22 are integrated into one chip is used, or the timepiece IC is further used.
It is also possible to use an LSI in which the function of the memory 20 is integrated in addition to the functions of 21 and the time calibration unit 22. Although not shown, a long-life battery such as a lithium battery is built in the card, holds the stored contents in the memory 20 and constantly drives the timepiece IC 21. Data exchange with each circuit in the card is performed via the data exchange unit 23. The memory 20 has a capacity capable of storing daily business data. Further, SRA is used as an element forming the memory 20.
A power-saving type such as M is used. Although not shown, a terminal for detecting the battery voltage is provided in the RAM card. When the RAM card is attached to the fare adjusting device A, the fare adjusting device A inspects this battery voltage, and if the voltage is below the specified voltage, prohibits the transfer of business data to the RAM card and at the same time the battery I try to encourage exchange. As a watch IC21, a fare adjustment device A
As with the timepiece IC 14 incorporated in, the one incorporating a crystal oscillator can be used. Initialization of the memory contents for clearing the business data in the RAM card is possible only by the data collecting device.

A highly accurate master clock 32 is used.
The master timepiece 32 may be composed of only a highly accurate timepiece mechanism, or may be a combination of an ordinary timepiece IC and a time calibration means, but the latter is more realistic. For example, a radio time signal can be used as the time calibration means. For example, a tuner for receiving a radio broadcast, a means for analyzing the wavelength of the received sound received from the tuner, and the like are built in the time calibration means, and at the same time as detecting the time signal, the current time engraved by the clock IC is 0 minutes 0 It is conceivable to automatically adjust to the second. It is also considered that a one-touch time calibration button that allows the current time to be set to 0 hour, 0 minute, and 0 second by pressing the button is provided, and a staff member who has intercepted the radio time signal presses this button to perform time calibration. The hour 0 minute 0 second to be set is selected to be the hour 0 minute 0 second closest to the current time. Normally, the time difference between the current time and the hour and minute and 0 second to be adjusted is within 5 seconds.
