BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted terminal device such as a taxi terminal device for recording vehicle operation data.

0002

2. Description of the Related Art A conventional taxi terminal device stores the boarding position and the alighting position in a memory in order to manage the operation status of the vehicle. In this case, the driver memorizes the location where the passenger picked up the vehicle, and after the passenger gets off the vehicle, uses the keyboard of the terminal device to input a numerical code that encodes the boarding position and the alighting position.

0003

[Problem to be Solved by the Invention] However, taxi drivers are very nervous when driving, so they sometimes forget the boarding position, enter the wrong numerical code when inputting the boarding position and the alighting position, or enter the numerical code incorrectly. There was a drawback that users sometimes forgot to input the information.

[0004] An object of the present invention is to enable automatic recording of vehicle operation data without bothering the driver.

[0005]

[Means for Solving the Problems] The means of the present invention are as follows. A position detecting means 1 (see the functional block diagram of FIG. 1; the same applies hereinafter) receives position information from, for example, a satellite, and detects the current position of the vehicle at any time. The instruction means 2 inputs specific instructions necessary for fare calculation, such as tariffs such as fare and vacant cars, depending on the operating status of the vehicle. The storage means 3 stores the current position detected by the position detection means 1 when the instruction means 2 gives an instruction.

[0006]

[Operation] The operation of the means of the present invention is as follows. The current position of the vehicle is detected by the position detection means 1 at any time, and when the instruction means 2 inputs a specific instruction necessary for toll calculation, the current position detected by the position detection means 1 is stored in the storage means 3.
is memorized. Therefore, vehicle operation data can be automatically recorded without bothering the driver.

Embodiment One embodiment will be described below with reference to FIGS. 2 to 5. Note that this embodiment is applied to a taxi terminal device. FIG. 2 is a block diagram showing the circuit configuration of the taxi terminal device. In the same figure, input section 11
is equipped with various keys such as numeric keys. When a key is operated on the input unit 11, an input signal corresponding to the key operation is input to the CPU 12.

[0008] The CPU 12 executes various processes such as processing according to the input signal inputted above and meter information reception processing. These various processes are executed based on a control program stored in the ROM 13 in advance. Also, CPU12
In addition to the key input unit 11 and the ROM 13, the RAM 1
4, a timer 15, a wireless device 16, a communication device A18, and a communication device B21 are connected.

The RAM 14 has data written/read under the control of the CPU 12, and has a latitude/longitude conversion matrix table 14a and an operation data file 14b. The latitude/longitude conversion matrix table 14a, as shown in FIG. This is a table for determining town names. The operation data file 14b includes driver number data such as "drno111" as shown in FIG.
, operation date data such as "2.11.2", boarding time and boarding location data such as "14:15 A town",
Alighting time and alighting place data such as "14:50
This is a memory file that stores data such as "Omachi", mileage data such as "11.5 km", and fare data such as "cash 1300 yen".

Returning to FIG. 2, the timer 15 measures the time required to detect and transmit the current position of the vehicle every fixed period of time, for example, 10 minutes, while the vehicle is running. The wireless device 16 wirelessly transmits detected current position data to a vehicle management center, etc., and has an antenna 17. The communication device A18 transmits each clock data sent from the satellite data receiving device 19 to the CPU 12. The satellite data receiving device 19 includes an antenna 20 and receives clock data transmitted from a plurality of satellites and having different frequencies. The communication device B21 transmits operation data output from the taximeter 22 to the CPU 12. The taximeter 22 is linked to the running of the vehicle, and outputs tariff data such as vacancy, rental mileage, and payment. This tariff data is data indicating the operating status of the vehicle.

Next, the operation of this embodiment will be explained based on FIG. FIG. 5 is a flowchart showing the operation of meter information reception processing. This meter information reception process is always executed while the taxi is in business.

First, in step S1, the communication device B21 receives tariff data output from the taximeter 22 and transmits it to the CPU 12. In step S2, it is determined whether the tariff data output from the taximeter 22 has changed from "vacant" to "paid". If NO in this step S2, proceed to step S3 and select YES.
In this case, the process advances to step S17. If the tariff data does not change and is "empty" or "rental", proceed to step S.
If the answer is NO, the process proceeds to step S3.

In step S3, it is determined whether the tariff data output from the taximeter 22 has changed from "paid" to "vacant". If NO in this step S3, proceed to step S4; if YES, proceed to step S
Proceed to step 11. If the tariff data does not change and is "empty" or "rental", the answer in step S3 is NO and the process proceeds to step S4.

[0014] In step S4, the count value of the timer 15 is added. In the next step S5, timer 15
It is determined whether the count value corresponds to a predetermined value, for example, "10 minutes." If NO in this step S4, the process returns to step S1, and if YES, the process proceeds to step S6. Now, if the count value reaches the predetermined value "10 minutes", the answer is YES in step S5 and the process proceeds to step S6.

In step S6, the satellite data receiving device 19
The antenna 20 receives clock data of different frequencies transmitted from a plurality of satellites, and the satellite data receiving device 19 outputs each received clock data to the CPU 12 via the communication device A18. In step S7, the CPU 12 takes in each clock data and calculates the current position of the vehicle, ie, latitude data and longitude data, based on the triangulation point method. In step S8, town name data is obtained by referring to the latitude/longitude conversion matrix table 14a (matrix conversion) using the calculated latitude and longitude data. In the following step S9, the obtained town name data is sent to the wireless device 16, and the wireless device 16 transmits this town name data as the current position of the vehicle to the vehicle management center of the taxi company. In step S10, the timer 15 is reset and the process returns to step S1.

Furthermore, when the driver picks up a passenger and the tariff data output from the taximeter 22 changes from "empty car" to "rental", this tariff data is transmitted to the communication device B2.

In step S17, similarly to step S6, the satellite data receiving device 19 is operated to receive clock data of different frequencies transmitted from a plurality of satellites through the antenna 20, and the satellite data receiving device 19 receives each received clock data. is output to the CPU 12 via the communication device A18. In step S18, as in step S7, C
The PU 12 takes in each clock data and calculates the current position of the vehicle, that is, latitude data and longitude data based on the triangulation point method. In step S19, similarly to step S8,
Based on the calculated latitude and longitude data, the latitude and longitude conversion matrix table 14a is referred to to obtain town name data, for example, "A town". In step S20, the obtained town name data "A-machi" is used as the boarding position, and time data such as "14:15" is added to the operation data file 14.
Store in b. After executing step S20, step S1
Return to

Furthermore, the tariff data output from the taxi meter 22 when the taxi arrives at the destination is used as "payment".
When the vehicle changes from "vacant" to "vacant", this tariff data is output to the CPU 12 via the communication device B21. As a result, YES is determined in step S3, and the process proceeds to step S11. In step S11, similarly to step S6, the satellite data receiving device 19 is operated to transmit clock data of different frequencies transmitted from a plurality of satellites to the antenna 2.
0, and the satellite data receiving device 19 outputs each received clock data to the CPU 12 via the communication device A18. In step S12, similarly to step S7, the CPU 12 takes in each clock data and calculates the current position of the vehicle, ie, latitude data and longitude data, based on the triangulation point method. In step S13, town name data such as "Omachi" is obtained by referring to the latitude/longitude conversion matrix table 14a using the calculated latitude and longitude data.

In step S14, the obtained town name data "Omachi" is used as the alighting position, and the time data, for example "1
4:50'' and is stored in the operation data file 14b. In the next step S15, the mileage is, for example, "11.5".
Based on fare data such as "km" and riding time, fare data such as "13
00 yen" is calculated by the CPU 12. Step S1
In step 6, the calculated fare data "1300 yen" and the travel distance "11.5 km" are stored in the operation data file 14b. After executing step S16, the process returns to step S1.

[0019] In the above embodiment, the current position of the vehicle was determined using a satellite; however, the current position is not limited to this, but various sensors such as a mileage sensor and a direction sensor may be installed on the vehicle to determine the current position. It's okay. Furthermore, in the above embodiment, the town name data is stored in the operation data file, but
The present invention is not limited to this, and the latitude data and longitude data themselves may be stored as the position data.
