Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a time correction device for an electronic taximeter, which has a clock element for accurately managing time.

[Conventional technology]

Electronic taximeters store various business data in their memory, which is used to check business fares and manage operation by, for example, calling up the data at the end of the day's business hours.

However, since conventional taximeters do not store various business data together with the corresponding times in their memory, they have no choice but to rely on the records of the crew.

In addition, by incorporating a clock into the taximeter, the time corresponding to the business data can be displayed along with the business data.
Although there are clocks that are stored in memory, the clocks used here are simply for telling the time, and the current situation is that the crew members themselves adjust the time.

[Problem that the invention attempts to solve]

In the case of such taximeters, the time is adjusted by the crew by operating the operation buttons or dials of the built-in clock, so there is a possibility that the crew could change the time for fraudulent purposes. There is.

This causes moral inconveniences, such as, for example, setting the clock ahead before the time when premium charges are allowed and conducting business at an illegal charge.

In addition, if the time adjustment by the crew is inaccurate or if they forget to do so, it can cause financial trouble with passengers, and if the time in the business data stored in memory is inaccurate. Therefore, there is a problem that analysis of sales data cannot be performed accurately and sufficiently.

[Means for solving problems]

In view of the above-mentioned problems, the present invention includes a toll calculation unit that counts tolls based on a pulse signal from a distance pulse generator that converts travel distance into an electrical pulse signal and travel time, and a display device for tolls, tariffs, etc. An electronic taximeter comprising: a tariff operator provided integrally with the display device; a connection terminal for a data transfer cable; a clock LSI for managing the current time; and a memory for storing various business data. mounted on a vehicle, and equipped with at least a data processing means, a storage circuit for business data, a time counter for managing accurate current time, and a connection cable for connection to a data collection device installed in a business office, etc. A cable is connected to a connection terminal of the taximeter, and various business data stored in the memory of the taximeter is transferred to a storage circuit of the data collection device, and managed by a time counter of the data collection device. This constitutes a time correction device for a taximeter, characterized in that the accurate current time is input to the clock LSI of the taximeter to update the current time.

[Effect]

The taximeter time correction device according to the present invention is constructed as described above, and the data for each taximeter operation is temporarily stored in the memory along with the time, and when the taxi returns to the office etc., the taximeter time correction device is configured as described above. The business data stored in the memory is transferred to the storage circuit built into the data collection device via the connection cable, and the accurate time managed by the time counter is transferred to the taximeter clock.
This is what is transferred to the LSI.

This time display section can be set at any location on the surface of the taximeter, and does not need to be provided in particular.

Reference numeral 5 denotes a transfer start button that is operated when transferring the business data temporarily stored in the taximeter 1 to another.

Reference numeral 6 denotes a central processing unit installed in the taximeter 1, into which the distance pulse output from the distance pulse transmitter (not shown) is input, and based on this, the CPU 6 counts and controls the fare, and the fare is calculated as the fare. It is configured to be displayed on the display section 2.

Reference numeral 7 denotes a clock LSI, which manages the current time and is a crystal oscillation type integrated circuit or the like.

8 is a random access memory (hereinafter referred to as RAM), and this RAM 8 temporarily stores business data whose count is controlled by the CPU 6.

In addition to the time data, this RAM 8 also records information on the actual vehicle based on the charge for each business, the total number of kilometers traveled, the number of kilometers actually traveled by the vehicle, the number of business hours, the number of times the unit charge is added after that, other necessary business data, and the clock data. Stores business data related to time data such as empty time and empty time as data.

Reference numeral 9 denotes a data collection device for calling and collecting business data temporarily stored in the RAM 8 of the taximeter 1, and a connection cable 10 having a jack 11 connectable to the taximeter 1 is provided at the tip.

13 is a CPU in the data collection device 9;
This is connected to taximeter 1 via cable 10.
The RAM 8 reads temporarily stored business data and stores it in the memory circuit 14.

Reference numeral 15 denotes a time counting section for managing accurate current time, and this time counting section 15 is made of an integrated circuit such as a crystal oscillation type similar to the clock LSI built into the taximeter 1.

Further, this time counting section 15 includes a time correcting section 16.
It is corrected as appropriate by the time correction section 1.
No. 6 is operated manually or in conjunction with a radio time signal, etc., and it is impossible for ordinary people such as crew members to make corrections.

Reference numeral 17 is a date setting circuit, which allows date data to be output from now to be input to the CPU 13.

Reference numeral 18 denotes a date change unit for changing the date data output by the date setting circuit 17, which outputs a signal when operated by any manual or automatic means, when the taxi business is past midnight. etc., the date is set so that there is no confusion regarding the date.

When the taxi service ends and you return to the taxi company's head office, office, etc., connect the jack 11 of the connection cable 10 provided on the data collection device 9 to the connection terminal 12 of the taximeter 1, and press the transfer start button. 5, the business data temporarily stored in the RAM 8 built into the taximeter 1 is called up by the CPU 13 on the data collection device 9 side and transferred to the storage circuit 14.

Once the transfer of sales data is completed, time counting section 1
The accurate current time managed by 5 is input to the clock LSI 7 of the taximeter 1, and

[Effect of idea]

The taximeter time correction device according to the present invention has the above-described configuration, and transfers the business data temporarily stored in the taximeter memory to a data collection device installed at the head office, sales office, etc. For the clock inside the taxi meter
In order to update the current time of the LSI to an accurate time, for example, by operating the time correction unit 16 once a day, and operating the date change unit at an appropriate time during the day, each The current time and date on the taximeter can always be set correctly.

Therefore, it is possible to eliminate the problem of lowering the reliability of business data related to time due to errors in the times of each taximeter, and to obtain correct business data.

Although the date is necessary when issuing a receipt, it is possible to eliminate such errors in the date of the receipt.

Since the time and date of each taximeter can be centrally managed as described above, it becomes unnecessary for each driver etc. to manage the time and date of each taximeter, and the effort required for this can be saved. Since it is impossible for the crew to correct the current time managed by the time counter of the data collection device and the clock LSI of the taximeter, fraud caused by time correction can be prevented.

Note that in a taximeter that does not require a date, the configuration related to the date can be omitted.
