During the need to cut off the connection between the car audio 20 and the speaker 21 or to adjust the output of the speaker 21, the call history stored in the internal backup memory 32 is output to the outside if necessary. Recognizing the communication circuit 44 and the charging start signal, the dial signal, and the termination signal for inputting the standard call charge and date change data, calculating the call charge according to the charging reference frequency, storing it in a predetermined memory, and outputting it to the display device. Each component necessary to And a microprocessor 43 for control.

The communication circuit 44 is a parallel communication circuit capable of connecting a notebook computer to an external device and communicating through RS232C, which is a standard communication standard, by specifying a call history stored in a memory by calling a printer connected to an external notebook computer. It is supported by program to print accordingly.

In mobile communication, the ring signal is made by turning on the pulses of 350Hz and 620Hz for 1 second and turned off for 2 seconds, and the busy signal is made by turning the 350Hz and 440Hz pulses on for 0.5 seconds and off for 0.5 seconds. Meanwhile, Teltone's M982 classifies 350Hz, 440Hz, 480Hz, and 620Hz into four pins and outputs the presence or absence of the corresponding frequency, which is in the form of ring tone, busy signal, and dial tone signal according to international standards. It is defined. When each frequency enters the ring decoder 36 composed of the M982 digital filter, the state of the corresponding pin becomes (+), so that the current call line state can be read. Therefore, the ring signal detected by the ring decoder 36 can be used as the charging start signal. In addition, in the present invention, even in the case where a call is made without ringing the phone, the state of each pin of the ring decoder 36 may be ORed to detect the voice signal on the line to perform the charging and use it as the charging start signal.

Since the date and time information in the base call rate and the call rate charging device are important data in billing, the driver cannot modify them arbitrarily, and if a reason for change occurs, the service provider can modify it through the communication circuit 44 from the outside. It is. The memory space of the internal backup memory 32 is divided into a reference frequency storage area for each region (international call), a password storage area for each user, a monthly total amount used for each user, a call history storage area, and a microprocessor ( 43).

The calendar memory 31, which manages the date and time information itself, uses a calendar circuit widely used for displaying the date and time of a computer, and uses a Dallas BQ3287, which is designed to operate by an internal backup power supply when the power is turned off. This can be used to read and set the year, month, day, hour, minute, and second data to a fixed address, and to modify the date and time information. Using this information, the monthly rates are aggregated and managed, and the rates are discounted for legal holidays, weekends and late night calls.

As the display device, there are five or more hexadecimal segments 29, the liquid crystal display device 30, and the light emitting diodes 38, 39, and the like. The hexadecimal segment 29 displays the current amount of use, and displays the liquid crystal display. The device 30 displays the date and time required for management and the total monthly usage amount for each user, and the call charges displayed in the octal segment 29 are periodically blinked until the payment completion key 40 is pressed. In addition, the separate light emitting diodes 38 and 39 are configured to display a discounted call state and a call enable / disable state according to origination / reception.

On the other hand, in the call rate charging device of the conventional mobile wireless public telephone, the charge start time and end time must be measured by itself, but in the call rate charging device of the mobile wireless public telephone using the digital method, the charge is started by communication. Since the timing and end time can be provided, it can be configured by adding a communication circuit instead of the tone decoder and the ring decoder, and in the case of the digital method, the call base frequency and the date can be remotely modified unlike the analog method without a separate modem. have. Therefore, the call billing device of the present invention can be connected and used to communicate with a mobile wireless public telephone by wire or wirelessly.

3 is a flowchart illustrating a call charge charging method according to an embodiment of the present invention.

Waiting for the input of the password or the lock release input signal with the power supply and if the signal matches the set password, the relay supplying power to the main body and the handset is turned on to make the mobile wireless public telephone available for communication (51, 52). . When the dial key is input, the tone decoder reads it and stores the outgoing phone number in a temporary buffer (53, 54). The ring decoder reads the current call line status, which is divided into ring tone, busy signal, and mobile communication connection failure. do. If there is no ring signal, it waits to receive another dial signal, and determines that the call is started with the other party from the end of the ring signal only when the ring signal is detected (55, 56). Then, after turning on the car audio relay, it reads the calendar memory, checks the call discount time period, measures the usage time, divides this time by the reference frequency, and displays the calculated amount on the hexadecimal segment. Since communication is interrupted, it is read into the input port, and the amount up to this point is displayed, summed up to the monthly total usage fee per user, and the call history is recorded in the internal backup memory (57, 58). In other words, to solve the problem of not recording when the startup is turned off during use, save the call history in the internal backup memory during the call, check whether the payment completion key is pressed, and display this data in the hexadecimal segment if it is not pressed. The call rate was managed even when the power was cut off. Then, when the call is over, the alarm light emitting diode flashes, the sound of the car audio is returned to its original position, and the driver collects the displayed call charge at a convenient time such as when the passenger gets off or after the call is completed. 60.

On the other hand, in order to prevent the call is made without ringing the phone ringing state of each pin of the ring decoder, it is possible to detect that the call was made by detecting the voice signal on the line after the dial.

The LCD displays the current date and time and the total amount of the current user's current month. The installed key can be used to inquire the total amount of the previous month. The call history has an index that manages the memory. If the recording area is full, write it on the old details. To change the password, change the method of entering the old password and the new password.If you connect the communication cable from the outside to the communication port, you can transfer the call history or the internal data. In the case of call discount time, the discount lamp is turned on.

When the vehicle is turned off, it is reset to the initial state and waits for the input of the password, and the same process is repeated as described above. It is easy to produce passwords and locks at the same time. Because of the many changes and forgotten passwords, computer locks make it easy to take over and manage.

As the present invention as described above, as the number of automobile supply increases, the traffic congestion becomes serious, and as a result, the social demand for providing a communication service even in a commercial vehicle is increasing. By providing a call charge device that can be easily attached and used on a wireless telephone, this service can be activated to provide a more convenient communication service for making and receiving calls wherever you want, even when you are in a commercial vehicle (taxi, etc.). In addition, it is simple, inexpensive, and can be miniaturized compared to any public telephone billing method, so it can be mounted on a small vehicle such as a taxi.

In other words, mobile radio phones are widely used, but commercial taxis still do not have a call fee charging device that can solve the billing problem as mobile wireless public telephones, so commercial taxis are a blind spot for communication. Considering the necessity of downsizing, preventing trouble caused by vehicle vibration, and post-payment, the usage fee is displayed immediately when the passenger finishes the phone call, so the driver solves the billing problem by allowing the passenger to receive the accumulated call fee when the driver gets off the bus. There is no need to prepare a separate call charge, which is convenient and stable, and even telecommunications operators can immediately use telecommunication services in commercial taxis without additional investment such as an approval system.

The provision of communication services in public transportation, the blind spot of telecommunications, is inevitable due to the progress of the information society and the development of society.In particular, taxis, unlike trains and buses, have a post-paid fare calculation. It is the most suitable call charge device for taxis because it is easy to maintain, less trouble, and no approval system is required, and the existing mobile wireless public telephone is a charge billing circuit, maintenance circuit, central management circuit, cellular transceiver, cellular connection device, cellular Compared to a modem, a card reader circuit, a card approval circuit, and the like, the present invention is simply composed of a billing and display circuit and a management system, and has a convenient point of use that a passenger does not need to perform a separate operation.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary skill.
