Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle data storage device for accurately and automatically recording business data of a vehicle such as a taxi, using a single printed circuit board on which a semiconductor memory element is mounted. It is related to.

Traditionally, in order to record business data such as the number of kilometers traveled by a taxi, the time required, and fares, the driver had to read the data displayed on the meter (2) for each customer and write it on a daily report form. As a result, errors and omissions are likely to occur.
Moreover, it takes time and effort to create, which has the disadvantage that the driver cannot concentrate on driving.

The present invention has been made to improve the above-mentioned drawbacks.
A portable storage device containing a semiconductor memory element was inserted into a data writing device installed in a taxi, business data was automatically written to this storage device, and this storage device was later installed in an office. It can be inserted into a data reading device to read and summarize recorded business data.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a vehicle data storage device (1) according to the present invention, which is constructed as follows. (2) is a printed circuit board the size of one business card;
2) includes CMo SRA as a semiconductor memory element.
M (3) (31...) is implemented with a capacity of 2 bytes to 8 bytes, and a code switch (4) for driver identification and a rechargeable battery (4) for retaining memory contents.
5) has been implemented. At the lower end of the printed circuit board (2), there is a data connector (6) and a charging connector (7).
is formed.

Figure 2 shows a data writing device (8) installed in a vehicle such as a taxi, and this data writing device (8) has connectors (6) (7) of the storage device (1). In addition, a meter α is connected to the meter α for counting business data such as the number of kilometers traveled by each customer and the time required and outputting the result as an electric signal. This meter O1) consists of a mileage counter aυ for counting the distance traveled, a required time counter H1 for counting the travel time, a fare counter (13), a passenger counter I, and a clock counter a2.

Figure 3 shows a data reading device (1G) installed in taxi company offices.
The main body (I7) of 16) is provided with an insertion port α mark for inserting the connectors (6) and (7) of the storage device (1), and also has an auxiliary storage device H such as a diskette or hard disk. combined.

Next, the function of the present invention will be explained in the form shown in FIGS. 5 and 6. Let me explain about Rochart.

First, the case where business records counted by the taxi meter QOI are written into the storage device W(1) will be explained with reference to FIG. Turn on the power of the data writing device (8), and insert and set the connectors (6) and (7) of the storage device (1) whose memory contents have been cleared in advance into its insertion port (9). If the question ``End of work?'' is No and the question ``Are there passengers?'' is YES, start the taxi, turn on the lever switch of meter 00), and display the number of kilometers traveled counter (11), the time required counter a, and Charge counter 0 starts counting. When the taxi reaches its destination and the passenger gets off, the question "Get off?" becomes YES, the lever switch of the meter α0) is turned off, and the counter (11) Q2) (1
3) stops counting. When the lever switch of this meter 00) is turned off (17), at the same time, the mileage counter (11), the required time counter 02), the fare counter α3), the number of passengers counter α, and the clock counter 0 (g) of the meter 00) are displayed. The tape signal is transferred to the storage device (1), and the number of kilometers traveled and the required time t [Which sales data is commercial
It is stored in the OS RAM (31 (31...). When the transfer is completed, the contents of the meter QO are cleared by the completion signal, and the meter α0) returns to its initial state. In this way, the business record for one ride is written into the storage device (1). This writing operation is performed for each passenger. When the day's work is finished and the question ``end of work?'' becomes YES, the power to the data writing device (8) is turned off, the storage device (1) is removed, and the writing operation is completed.

Next, the case where the data reading device (16) reads the contents of the storage device (1) into which business records have been written as described above will be explained based on FIGS. 6 and 4.

Turn on the power of the data reading device (16), and
The connectors (6) and (7) of the storage device (1) are inserted into the connectors 181 and reading is started. In this reading, a driver code reading check is first performed, and then business data about the driver is read. At this time, data for each passenger is read, the tape is transferred to the auxiliary storage device, and the number of passengers is counted for each transfer. When such reading of data for each passenger is carried out for all passengers in one day, and the "Data complete?" becomes YES, the data for one day per driver will be as shown in Figure 4, for example. It is printed out as a daily report (a).

Then, the memory of the storage device (1) is cleared, reading is completed, and business data of other drivers is read in the same manner as described above. When the reading of the business data of all drivers is completed in this way, "All data completed?" becomes YES, and the power of the data reading device α0 is turned off to end the reading operation.

Since the present invention forms a storage device by mounting a semiconductor storage element on a printed circuit board as described above, unlike storage devices using general-purpose magnetic cassette tapes or flexible disks, Can withstand use in vehicles. Moreover, the semiconductor memory element can be made small and lightweight, and since it is mounted on a single printed circuit board, it is convenient to carry.

Furthermore, if the storage device according to the present invention is inserted into a writing device installed in a taxi and data is written therein, business records can be automatically stored. There is no need to fill out information, so there are no errors or omissions, and it saves the driver's time and effort, allowing him to focus solely on driving.

Furthermore, if the contents of the storage device into which data has been written as described above are read by a reading device installed in the office, data aggregation, daily report creation, etc. can be done accurately and easily.
