Description

How to automatically set the time of digital key phone system

The present invention relates to a digital key phone system, and more particularly, to a method for automatically setting the time of the key phone system by using an automatic time guide voice message provided through a time automatic voice guidance service of a telephone station in a digital key phone system.

These days, the digital keyphone system used in most companies or offices has a system configuration as shown in FIG. Such a digital key phone system has a plurality of extension terminal subscribers and various additional functions, and connects trunk lines and extensions between the extension subscribers by means of telephone lines (commonly referred to as trunk lines) in the premises switching facility and the belonging switching handling section. It will play a role. That is, as shown in FIG. 1, the key phone main device 100 is connected to the public network (PSTN) 120, and an extension call between the trunk line call and the terminal through the general terminal 130 and the key phone terminal 110 joined to the key phone main device 100 of the digital key phone system. And a plurality of terminals are subscribed according to the subscription capacity of the key phone system. In the figure, a voice mail system (VMS) 140 is illustrated as an example of an additional function, which provides a voice mail service as a voice mail device. The MAP150 is a maintenance computer that performs maintenance management of the main device 100, which is operated by a system operator.

On the other hand, the key phone terminal 110 subscribed to the key phone system as described above has a display device such as an LCD, the terminal user can recognize a variety of information, so that the user of the terminal 130 is more convenient than the user. An important one of the various information displayed on the LCD is to display the current time. In order to display the current time in a conventional system, a predetermined timer or clock circuit is added to the main device 100 so that the time is set by the operator so that all the key phones are displayed. The set time is displayed on the terminal. However, when the error of the operator or a time error that occurs due to a long time occurs, the set time is also inaccurate due to the fact that it is almost impossible for the operator to set the correct time. In particular, it is important to inform all members of the correct time when tasks such as accurate time setting between the members of the organization are necessary, and this function is not implemented in the conventional system.

Accordingly, an object of the present invention is to provide an accurate time to terminal subscribers subscribed to the digital key phone system.

It is also an object of the present invention to perform time correction in the system itself without the operation of a digital key phone system operator so that the current time is correctly displayed in hours, minutes, seconds, and units.

Accordingly, the technical object of the present invention is to implement a method for automatically setting the time of the key phone system by using an automatic time guide voice message provided through a time automatic voice guidance service of a telephone station in a digital key phone system.

In order to achieve the above object, the present invention adds a voice signal detection circuit to a main device of a digital key phone system, dials a telephone number for receiving a time automatic voice guidance service of a telephone station, and provides an automatic time guide voice message provided by the service. Is provided, the voice signal detection circuit detects and analyzes the result, and compares and corrects the time set in the existing key phone system, and sets the corrected time as the time of the key phone system.

DETAILED DESCRIPTION Hereinafter, a detailed description of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In the following description of the present invention, detailed descriptions of related well-known functions or configurations will be omitted when it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. The terms to be described below are terms defined in consideration of functions in the present invention, and may be changed according to the intention or custom of the user or chip designer, and the definitions should be made based on the contents throughout the present specification.

First, FIG. 2 is a block diagram of a digital key phone system showing a state in which a voice recognition processor is added to a main device of a digital key phone system.

Referring to FIG. 2, a digital key phone system is largely divided into a key phone main unit and a key phone terminal. The key phone main unit is a main controller of the system and controls all operations of the key phone system and registers a plurality of terminals. Looking at the internal block configuration of the key phone main unit, the switching control circuit unit 210 transmits and receives a voice signal and a data signal between the key phone main unit and the key phone terminal unit. The microprocessor 212 is a control unit of the key phone main unit, and performs overall operations of the main unit. The trunk line connection unit 214 allows the system to be connected to an external telephone line, thus allowing the user and subscriber of the key phone system to make an external telephone call. The voice recognition and tone detection circuit unit 216 detects and analyzes a voice signal and a tone signal input through an external trunk line connected to the trunk line connecting unit 214 and transmits the same to the microprocessor 212. Timer circuit 218 generates day and time data for delivery to microprocessor 212. The tone generator 220 generates various tones such as a DTMF signal. The key phone terminal unit is directly used by a general subscriber of the digital key phone system. The key phone terminal unit is connected to the key phone main unit to be controlled by the main unit, and includes a handset unit, a speaker unit, a dial button, and a function button. . The key-phone terminal is shown in perspective and connected state in Figure 1 described above. Looking at the internal configuration of the key phone terminal unit, the switching control circuit unit 222 to receive and transmit voice signals and data between the key phone main unit and the key phone terminal unit. The microprocessor 224 is a main controller of the key phone terminal unit, and the keyboard 226 is composed of numeric keys and function keys so that data and telephone numbers can be input by the user in the key phone terminal unit. The ROM 228 stores an operation program of the microprocessor 224, and the RAM 230 performs a function of input / output of data required for the operation of the microprocessor 224. The LCD control unit 232 is a display unit of the key phone terminal unit and displays information and messages necessary for the user. The LED controller 234 is an example of a display device that allows a user to easily recognize whether a predetermined function is set.

In the digital key phone system having the configuration of FIG. 2, the operation is performed by a method as shown in FIG. 3.

3 is a flowchart illustrating an automatic time setting method of a digital key phone system according to the present invention.

Referring to FIG. 3, in operation 310, the keyphone system is in an initial state. In operation 312, the microprocessor 224 of the key phone main apparatus occupies an external trunk line through the trunk line connecting unit 214 according to a pre-programmed and stored command. In step 314, it is determined whether the dial tone is confirmed to check whether the external trunk line occupation of step 312 is connected. If it is determined in step 314 that the dial tone has not been confirmed, the state in which the CO line is occupied is canceled in step 315, and the operation 312 is performed again. If it is determined in step 314 that the dial tone is confirmed, in step 316, the microprocessor 212 of the key phone main unit performs dialing to the telephone number to which the automatic time guide voice service is provided through the tone generator 220. Although the guide service telephone numbers are different for each country, the description of the present invention will be described using an example of the Republic of Korea, where the telephone number is '116'. Therefore, in step 316, '116' is dialed. In step 318, the automatic time guide voice message guided according to the dialing result of '116' is detected through the voice recognition and tone detection circuit 216, and the analysis and data are read. When the detection and reading operation of the step 318 is performed, the current time previously set in step 320, that is, the time by the timer circuit 218 of the digital key phone system and the time read in the step 318 are compared and determined. If there is a difference between the read times, correct the time of the system with the read times. The corrected time is transmitted to the key phone terminal, so that the LCD display unit 232 of the key phone terminal is displayed in step 322. That is, the time of the digital key phone system is changed according to the time provided by the '116' service. The display operation is performed, and in step 324, the microprocessor 212 of the keypad main unit determines whether a time update period arbitrarily set by the user is reached. In this description, one month, that is, 30 days is set as the renewal time. That is, the operation of step 312 is repeated every 30 days.

As described above, the present invention displays the correct time to the users in the digital key phone system, thereby increasing the ease of use.

In addition, the present invention has the effect that the correct time is automatically corrected without the system operator input or correct the time separately.
