The present invention relates to a taxi meter data transmission device and a method of transmitting the same, which makes it possible to transfer data very simply and easily from a taxi meter of a completed taxi.

As is well known, the data of the taxi meter should be transferred to a dedicated reading device or computer immediately after the vehicle returns.

For this purpose, the management personnel who were waiting immediately after the return of the taxi, which had conventionally been in operation, carry out the dedicated reader to be interconnected with the connector of the taxi meter, and then operate the dedicated reader to transmit the data of the taxi meter to the dedicated reader, After the taxi returned after the operation, the management agent who had been waiting for the data obtained from the taxi meter was taken out by taking the data pack inserted in one side of the taxi meter and taking it to the dedicated reader to read the data from the dedicated reader.

Therefore, it is necessary to carry out the printing work after collecting the taxi meter data while carrying a bulky reading device and to collect a separate person for this, which adds to the burden of labor costs.

The present invention wirelessly even if the taxi driver is connected to the taxi meter using a single remote control provided in the guard room of the company entrance after the return of the taxi to solve these various problems even if the taxi meter does not have a wireless transmission means By allowing data to be immediately input to a dedicated reading device or computer installed in an office, etc., it is a very economical structure and the data of the taxi meter can be transferred with a very simple operation. The data is printed immediately after the taxi returns. The purpose of the present invention is to make it possible to save labor costs while at the same time eliminating the need for a separate time for printing.

The present invention allows the CPU of the taxi meter to transmit its data to the remote control to achieve this purpose, the remote control initiates data transmission of the taxi meter using a known data transmission and reception means and receive the data immediately By transmitting such data wirelessly to a dedicated reader or computer at a location, it is possible to transmit data from multiple taxi meters so that data can be transmitted to a dedicated reader at another location without having to use an expensive wireless transmission device. When described in detail by the preferred embodiment of the accompanying drawings, which are intended to be as follows.

The present invention can be implemented in a preferred form by the configuration as shown in FIG. As can be seen from this, a display device 4 composed of a charge indicator 1, a function number indicator 2 and a function content indicator 3, a charge data memory 5 with charge data input therein, A buzzer 6 for alarming abnormality, a driving data memory 7 for storing driving-related data, and a function key 8 for selecting and operating various functions are provided through the input / output port of the CPU 9. In the known taxi meter 14, the keypad 15 capable of inputting various data, the buzzer 16 for generating an alarm sound in the event of an abnormality, the run switch 17 and the mode switch. 19 allows the CPU 18 connected to the input / output port, the input / output port of the CPU 18 and the input / output port of the taxi meter 14 to be connected to the connector 32 which is a known connection means A, and the CPU. Connected to the output port (18) to amplify the signal and By amplifying and amplifying the power to radiate a high frequency output to the antenna 24, the radio transmission unit 23 and the high frequency signal introduced from the antenna 24 are amplified, tuned, detected, and filtered to obtain a digital signal. The remote controller 26 is configured by applying the output of the wireless receiver 25 to the input port of the CPU 18, and the wireless transmitter 29 having the same structure as that provided in the antenna 27 and the remote controller 26 as described above. ) And the wireless receiver 28 to the output and input ports of the dedicated reader 30 and the computer 31.

The data transmission according to the present invention as described above allows the remote controller 26 and the CPU 9 of the taxi meter 14 to be interconnected after the taxi is completed and the remote controller 26 by turning the mode switch 19 on or off. It is possible to select to start the operation after pressing the run switch 17 to the automatic transmission and reception state that is immediately started by) or to a manual transmission and reception state to prevent battery current consumption when the remote controller 26 is in standby.

When the operation of the remote controller 26 is started as described above, the call meter is transmitted to the taxi meter 14, and the taxi meter 14 waiting for transmission transmits the received data to the remote controller through the connector 32, which is the connection means A. 26), which can be received by the remote controller 26 and transmitted wirelessly to a dedicated reading device installed elsewhere.

That is, in the present invention, after the taxi is finished, the taxi meter 14 and the remote controller 26 use infrared rays as shown in the connector 32 or the third road shown in the first road, which is the connecting means A. By operating the mode switch 19 and the run switch 17 after the connection is made, the CPU 18 of the remote controller 26 immediately outputs the call code to the output port by the program of re-appearance, and as a result, the taxi meter 14 Is applied to the input port of the CPU (9).

As a result, the CPU 9 decrypts it and recognizes that it is an instruction for instructing data transfer. At the same time, when the run switch 17 of the remote controller 26 is pressed and released, the CPU 18 outputs a call code to the output port to be amplified, pulse-modulated, and amplified by the wireless transmitter 26 to the antenna 24. Since the call code radiates the radio waves carried, it is also induced in the antenna 27 connected to the dedicated reader 30 installed in another place of the Konri office and amplified, tuned, detected, and filtered by the wireless receiver 28, and the CPU of the dedicated reader 30 It is applied to the input port and recognizes that the current call code has been input and is ready to receive data such as power supply from each part of the circuit for receiving data immediately.

Then, the CPU 9 of the taxi meter 14 reads the data of the driving data memory and uses the connector 32 or the infrared light-receiving element using infrared rays, and the connecting means A composed of the driving circuits of the remote controller 26. Since the data is transferred to the CPU 18, the CPU 18 amplifies and pulse modulates the data, and then performs high frequency power amplification to radiate the antenna 24.

Therefore, the radiated radio waves are induced in the dedicated reader 30 installed in another place such as the management office or the antenna 27 connected to the computer 31, and amplified, tuned, detected and filtered by the receiving unit, and then reproduced as digital signals. It is applied to the input port of the reader 30 or the computer 31.

In this process, after the data input of the vehicle is completed in the storage device of the dedicated reader 30, the shortened end code is transmitted from the taxi meter 14 to the remote controller 26 and from the remote controller 26 to the dedicated reader 30. Therefore, the CPU of the dedicated reader 30 determines that the input of the data is completed, checks whether there is an error, such as an error, in the contents of the input data, and stops the operation when there is no error. If an error is found at this time, a specific code is output through the output port of the CPU immediately.

Therefore, the amplified and pulse-modulated in the wireless transmitter 29, the power is amplified and applied to the antenna 27, this time the radio wave in the form of a pulse-modulated form of the code is modulated to the antenna 24 of the remote control 26 . Therefore, this is a situation in which the corresponding code is input to the input port of the CPU 18 after being amplified, tuned, detected, and filtered by the wireless receiver 25.

Therefore, the CPU 18 recognizes that an error has occurred in the data previously transmitted, generates an alarm sound to the buzzer 16, and repeats the above-described process in the same manner to retry the data transmission.

In addition, even when this process is attempted several times, if an error occurs continuously and an alarm sounds from the buzzer 16 of the remote controller 26, the user may receive data of another taxi once at the discretion of the taxi meter 14 ), Of course, must take appropriate measures such as repair and retry the transmission of data.

In this way, the present invention combines the taxi meter 14 and the remote control 26 with the connecting means (A) and only a simple operation of pressing the run switch 17, the dedicated reading device of the place where all the data of the taxi meter 14 is different It can be transmitted to the computer 31, so that it is not necessary to secure a separate working personnel can be reduced labor costs, in the present invention without having to mount expensive equipment for high-frequency transmission and reception per taxi meter (14) Using the remote control 26 according to the present invention installed in the guard room installed in the taxi company entrance in common to perform high-frequency transmission and reception for data transmission, so the additional burden of the equipment cost according to the present invention is easy to be practical. Dedicated reader 30 and computer 31 will print the data immediately upon receipt, so you need to spend extra time for printing. Since there are no useful effect of being able to improve the efficiency of administrative tasks.
