JPS615668A - Key telephone set with charging display - Google Patents

Abstract

PURPOSE:To attain charging with minimum set data from a master set even to the use in a foreign country or the change in the domestic charging system by providing a unit charge initial set means for setting the unit charge at power-on set. CONSTITUTION:At the power-on set of a key telephone set, the domestic standard unit charge 10 yens is set initially by a unit charge initial set means 8. Thus, in case of the normal charge display, the communication command is analyzed by the unit talking time via a communication reception section 15 between master sets and the charging is displayed by setting the unit talking time. When the unit charge is changed for the use in a foreign country, the unit charge is changed by applying communication command analysis through the superimposition of the unit charge to be changed on the command communicated from the master set. Thus, the new unit charge is applied for the succeeding charge display.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a button telephone device with charge display that can be adapted to any charge system by simple modification.

Conventional configuration and problems thereof Generally, billing is expressed by cumulative addition of unit charges for each unit call time, and the distance is adjusted by adjusting the length of the unit call time. For this reason, although it is impossible to change the unit charge in most cases, in the unlikely event that the billing system changes, it will be necessary to change the unit charge in the case of use in a foreign country.

FIG. 1 is a block diagram of a button telephone that constitutes a conventional button telephone device with billing display. The configuration of this conventional example will be explained below with reference to FIG. 1. In Figure 1,
1 is a communication command analysis means, and a main device (not shown)
This is to analyze the contents of the command from. Reference numeral 2 denotes unit call time setting charging start means, which sets a unit call time and starts charging display in response to a communication command from the main device. Reference numeral 3 denotes billing termination means, which terminates billing display in response to a communication command from the main device.

Reference numeral 4 denotes a charging means, which performs charging by adding a predetermined unit amount (for example, 10 yen) for each set unit call time.

Reference numeral 5 denotes a charge display means, which includes a display driver for displaying the data on a liquid crystal display based on the data charged by the charge means 4.

Next, the operation of the above conventional example will be explained. In FIG. 1, when the main device sends information on the unit call time and a command to start billing, the communication command analysis means 1 sends the unit call time setting billing start means 2 to the pushbutton telephone side for the unit call. The time is set, the charging means 4 starts the charging process, and each time a unit call time is reached, 10 yen (a fixed value for the button telephone) is added, and the charging fee display means 5 displays the LCD display of the button telephone. to display it. However, in the above conventional example, since the unit charge is fixed on the key telephone side, only the unit talk time can be set from the main device side.

Therefore, there are no problems in normal operation, but there is a problem in that when using the telephone in a foreign country or changing the billing system, it is necessary to make several types of button telephones.

On the other hand, as shown in FIG. 2, a key telephone device is also known in which a unit charge setting means 6 is added in order to improve the above-mentioned drawbacks.

However, in this case, although the versatility is improved, image information of the unit charge and unit call time is required from the main device at the start of billing, and communication with the main device takes time due to the increase in setting data. There was a problem that it took a while.

Purpose of the Invention The present invention eliminates the above-mentioned drawbacks of the conventional technology, and enables accurate billing with minimal setting data from the main device even when used in a foreign country or when the domestic billing system is changed. The object of the present invention is to provide an excellent button telephone device with billing display.

Structure of the Invention In order to achieve the above object, the present invention initializes a standard unit charge at the time of power-on reset on the key telephone side, and normally charges only based on unit call time data, so that it can be used in foreign countries or domestically. If the unit charge changes due to a change in the billing system, etc., all you need to do is change the unit charge mentioned above. make the payment,
It is configured so that billing can be displayed using a minimum amount of data.

DESCRIPTION OF EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a block diagram showing the configuration of an embodiment of the button telephone device of the present invention. In FIG. 3, 7 is a communication command analysis means, which analyzes the contents of commands from the main device. Reference numeral 8 denotes unit charge initial setting means, which initializes the unit charge at the time of power-on reset. Reference numeral 9 denotes a unit charge changing means, which changes the unit charge set by power-on reset using a communication command from the main device. Reference numeral 10 denotes unit call time setting charging start means, which sets unit call time and starts charging display in response to a call command from the main device. Reference numeral 11 denotes billing termination means, which terminates billing display in response to a communication command from the main device. Reference numeral 12 denotes a charging means, which performs charging based on a set unit charge and unit call time.

Reference numeral 13 denotes a charge display means, which includes a display driver for driving a liquid crystal display or the like based on the data charged by the charge means 6.

FIG. 4 is a block diagram showing the specific configuration of the above embodiment. 1) 114 is a power-on reset switch, 1
5 is a receiving unit that receives command data from the main device; 1;
6 has an arithmetic control section 17 inside. Storage section 18, output section 19.
A microcomputer 21 having an input section 20 is a part of a liquid crystal display driver that receives billing data from the microcomputer 16 and performs dynamic display on a liquid crystal display 22.

Next, the operation of this embodiment will be explained. FIG. 5 shows the main part of a flowchart under the control of the microcomputer 16. When the key telephone is power-on reset, the unit charge initial setting means 9 initializes the domestic standard unit charge of 10 yen in step 24. As a result, in the case of a normal charge display, the communication command is analyzed in step 23 using only the unit call time data via the inter-main device communication receiving section 15, the unit call time is set in step 26, and the unit call time is set in step 28. At 32, billing is displayed. In addition, when changing the unit charge for use in a foreign country, etc., the unit charge to be changed is added to the command and communicated from the main device, the communication command is analyzed in step 23, and the unit charge is changed in step 25. Make changes. Therefore, the new unit charge will be used for subsequent charge display.

Effects of the Invention The present invention has the above-mentioned configuration, and can sufficiently cope with the present billing system by simply changing the data, and provides a flexible billing display with minimal billing data. It has the advantage of being able to go anywhere.
