DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
So-called PC Tel to which the control system of the present invention is applied
An outline of the ephony system will be described.

In FIG. 1, a personal computer 1
00, the PBX control means 102 is an LCD (li)
Only the display information a of the liquid crystal display is notified to the state change detecting means 103 without directly notifying the main control means 101. The state change detecting means 103 detects a state change or a time when the other party's telephone number is determined by performing processing described later with reference to FIGS. 2 to 5, and notifies the main control means 101 of only necessary information. .

For example, considering the state of dialing on a telephone, dial information is normally displayed on the LCD sequentially from left to right, but the speed of updating the LCD display is faster than the speed of human operation. , The display in which the dial number is increased by one character is repeated. However, the application running on the PC only needs to know the destination that was finally dialed, so that the telephone number in the middle of dialing is unnecessary. Also, when updating the LCD display, normally, it is not performed to rewrite all the display areas of the LCD with new display information and to rewrite only a portion where the display information has changed.

Therefore, using these characteristics, the state change detecting means 103 can detect a state change or a time when the other party's telephone number is determined by performing the processing shown in FIGS. it can.

First, as shown in the flowchart of FIG. 2, when the LCD display information a for the digital multi-function telephone is newly received, every area of the LCD is sequentially rewritten every time the above-mentioned LCD is displayed. The frame detection process (FIG. 3) is performed in consideration of the characteristics of the frame. Then, the display character information is compared with the previous frame, the position (character position) of the portion where the display content is changed is checked, and the character position of the portion where the display content checked in the previous frame is changed is compared. However, if the character position of the portion where the display content of the current frame has changed is after the character position of the portion where the display content of the previous frame has changed, it is assumed that the display such as the dial number is continued. Judgment, the LCD display content notification b is not notified to the main control means 101, and the character position of the portion where the display content of the current frame has changed is replaced with the character position of the portion where the display content of the previous frame has changed. Before
It is determined that the display content has changed to another display content, and the display information of the previous frame is notified to the main control means 101 as the LCD display content notification b.

As will be described later with reference to FIG. 4, even if the display contents do not change for a certain period of time due to the timer interrupt processing, it is determined that the state is determined by the current display contents, and the current display contents are determined. The display information of the frame is notified to the main control means 101 as the LCD display content notification b.

As described above, according to the present invention, the main control means 101 does not need to perform a processing operation based on unnecessary LCD display contents, so that the load on the main control means 101 can be reduced and the main control means 101 can stably operate. In addition, necessary information such as a telephone number and a call state can be reliably notified to an application running on a PC.

Hereinafter, a P to which the control system of the present invention is applied will be described.
A configuration example of an embodiment of the C Telephony system will be described.

FIG. 1 is a diagram showing a P as an embodiment of the present invention.
FIG. 1 is a block diagram illustrating a configuration example of a C Telephony system. In the figure, a personal computer 1
Reference numeral 00 denotes an exchange of information with the private branch exchange 200 via the PBX communication control means 110 at the interface (I / F) of the digital multifunction telephone.

The PBX control means 102 constituting the personal computer 100 controls the PBX communication control means 110, and displays information (LCD (or LED) display information, voice path control information, ringer control information, etc.) from the private branch exchange 200 to the digital multifunction telephone. Information of L
The CD display information a is notified to the state change detecting means 103, and the other information is directly notified to the main control means 101.

The PBX control means 102 converts the button / hook status control request received from the main control means 101 into a
The private branch exchange 200 is notified via the X communication control means 110.

The state change detecting means 103 is shown in FIGS.
By performing processing as described later with reference to FIG. 5, a state change or a destination telephone number determination is detected. The main control means 101 includes the PBX control means 10
2 performs predetermined processing based on the various information supplied from
The content displayed on the LCD is controlled based on the display content notification b.

The PBX communication control means 110 shown in FIG. 1 is a circuit for converting a control signal from the personal computer 100 into a control I / F signal unique to each private branch exchange.
Further, since it is not directly related to the present invention, a detailed description of its configuration and operation is omitted.

The main control means 101 in FIG. 1 depends on the control specifications of a digital multifunction telephone which can be connected to each private branch exchange, and is not directly related to the present invention. Is omitted.

Next, the operation of the state change detecting means 103 of FIG. 1 will be described with reference to the flowcharts of FIGS.

First, as shown in the flowchart of FIG. 2, when the LCD display information a for the digital multi-function telephone is newly received, all the areas are sequentially rewritten each time the display is performed. , A frame detection process (FIG. 3) is performed. Normally, when the LCD display of a multifunction telephone is garbled or not displayed due to a transmission error or the like, every area of the display is changed so that the state does not continue for a long time. Are sequentially rewritten, and the display change of only the changed portion is not performed.

Therefore, as shown in FIG. 3, at the timing when the display character position returns to the front, it is considered that one frame has ended, and the processing at the end of displaying one frame is performed.

That is, in step S11, it is determined whether or not the display position returns to the front. When it is determined that the display position returns to the front, the process proceeds to step S12. Step S1
In step 2, the change point position information of the current frame is stored in the storage unit 104 as the change point position information of the previous frame. Next, the process proceeds to step S13 to clear the change point position of the current frame. In step S14, the display content (current display information) currently displayed in the frame is stored in the storage unit 104, and the process ends. And FIG.
Go to step S2. On the other hand, if it is determined in step S11 that the display position does not return to the front, the processing ends, and the process proceeds to step S2 in FIG. In this case, it is assumed that the display position does not return to the front, and the process proceeds to step S2 as it is.

In this way, when the LCD display information a is received and the frame detection processing is completed, the process returns to FIG. 2, and the following processing is performed in order to detect a state change or a destination telephone number determination. For example, considering the state of dialing on a telephone, dial information is normally displayed on the LCD sequentially from left to right, but since the speed of updating the LCD display is faster than the speed of human operation, Updating to a display in which the dial number is increased by one character is repeated. However, the application running on the PC only needs to know the destination that was finally dialed, so that the telephone number in the middle of dialing is unnecessary. Therefore, the following processing is performed.

That is, in step S2, the display character information of the previous frame and the display character information of the current frame are compared. And
When the display character information of the current frame and the display character information of the previous frame are the same, the process ends. On the other hand, if the predetermined characters of the display character information of the current frame and the previous frame are different, step S3
Proceed to.

In step S3, it is determined whether or not a character different from the previous frame detected in step S2 and the current frame, that is, a change point is a change point detected first in the current frame. If it is determined that the change point is not the first change point detected in the current frame,
Since there is a possibility that the same change point has been detected redundantly, the process is terminated. On the other hand, if it is determined that the change point is the first change point detected in the current frame, the process proceeds to step S4. In step S4, the position of the detected change point is stored in the storage unit 104.

Next, the operation proceeds to step S5, where the storage means 10
The position of the character where the display content of the previous frame stored in 4 has changed (the position of the change point) and the position of the character where the display content of the current frame has changed are checked. Compare the position of the character in the part where the display content has changed in the current frame with the position of the character in the part where the display content has changed in the current frame, and compare the position of the character in the part where the display content has changed in the previous frame. If the position of the character whose display content has changed in the current frame is later (to the right) than the position, or if the positions of both characters are the same, the display of the dial number etc. is continued. The main control means 1 determines that the notification is
01 is not notified, and the process ends.

On the other hand, the position of the character where the display content has changed in the previous frame is compared with the position of the character where the display content has changed in the current frame. If the position of the character where the display content has changed in the current frame is before (if it is on the left side) the position of the character where the display content has changed, the display content has changed. And the process proceeds to step S6. In step S6, the main controller 101 is notified of the display information of the previous frame as the LCD display content notification b.

Once the main control means 101 is notified as the LCD display content notification b, the LCD display content notification b is not notified until the LCD display information a of the next frame is received in the frame detection processing of step S1. . After the process shown in FIG. 2 is continuously executed at a predetermined time interval, when the LCD display information a of the next frame is received in the frame detection process of step S1, as shown in FIG. Is updated, the change point position of the current frame is stored as the change point position of the previous frame, and the change point position of the current frame is cleared. Then, as in the case described above, the processing from step S2 in FIG. 2 is repeatedly executed.

However, if the state in which the display content of the LCD does not change continues only by the processing described above, the display content currently displayed on the LCD will not be notified to the main control means 101 forever. . Therefore, as shown in the flowchart of FIG. 4, even if the display content does not change for a predetermined reference time due to the timer interrupt processing, it is determined that the state is determined by the current display content, and the current frame is determined. The display information is notified to the main control means 101 as the LCD display content notification b.

That is, in step S21 of FIG. 4, it is determined whether or not the state in which the display content does not change has continued beyond a predetermined display stabilization time. If it is determined that the state in which the display content does not change has continued beyond the predetermined display stabilization time, the process proceeds to step S22, and the display of the current frame is sent to the main control unit 10 as the LCD display content notification b.
Notify 1.

Next, in step S23, the position of the change point stored in the storage means 104 is cleared, and in step S24, the display information (current display information) of the current frame is stored in the storage means 104. After that, the process ends.

If it is determined in step S21 that the state in which the display content does not change does not continue beyond the predetermined display stabilization time, the process is terminated.

FIG. 5 is a flowchart for explaining an initialization process for performing the above-described operation.
That is, in step S31, a timer interrupt processing timer and an interrupt process are registered. Next, the process proceeds to step S32 to clear the change point position of the current frame and the change point position of the previous frame stored in the storage unit 104. Next, in step S33, the display information of the current frame and the display information of the previous frame stored in the storage unit 104 are cleared, and the process ends.

FIG. 6 shows the processing contents described above as a specific L
LCD when applied to the display pattern of CD display information a
The notification timing of the display content notification b is shown.

First, it is assumed that nothing is displayed on the LCD. In this state, the LCD display indicates "100-> [
]], The change point is the first digit ("1")
And the LCD display contents are not notified (not notified). LC
When the D display is updated to "100->[1]", the change point is the seventh digit ("1"), which is after the previous change point first digit, so the LCD display content is not notified. When the LCD display is updated from "100->[10]", the change point is 8
Since this is the digit (“0”), which is after the seventh digit of the previous change point, the LCD display content is not notified. The LCD display shows "10
0 −> [101] ”, the change point is at the ninth digit (“ 1 ”), and after the previous change point at the eighth digit, L
Do not notify the CD display. The LCD display shows “100 == [1
01]], the change point is the fourth digit (“=”)
Since the previous change point is before the ninth digit, the display information (100-> [101]) of the previous frame is notified to the main control means 101 as the LCD display content notification b.

Also, the LCD display indicates "100 == [10
1]], the timer is timed out and the display information (100
== [101]) to the main control means 101 as the LCD display content notification b.

In the above LCD display, the numbers in brackets [] indicate the extension number, "->" indicates that the extension partner is being called, and "==" indicates the telephone call with the extension partner. Indicates that it is inside.

As described above, in the present invention,
The following effects are obtained. The first effect is that, when a state change or a destination telephone number is determined, only the LCD display information a necessary for the application is notified to the main control means 101 as the LCD display content notification b.
That is, an accurate and stable operation can be realized.

The second effect is that all the LCD display information "a" at the time of the state change is notified to the main control means 101, so that only the LCD display information "a" when the LCD display contents are stabilized is simply processed. The difference is that it is possible to reliably recognize a change in the call state.

The third effect is that when the display characters are increased one character at a time, the LCD display information a is
Since the main control means 101 is not notified as the D display content notification b, the user can input only certain input information such as the determined destination telephone number or the determined account number through an application (voice mail or the like) operating on the PC. Can be displayed or recorded.

The fourth effect is a common effect for a system in which a PC Telephony system is constructed by using the I / F of a digital multi-function telephone as it is, but the I / F of the digital multi-function telephone is used as it is. Since it is used, a PC Telephony system can be constructed without increasing the load on the main device (private branch exchange 200) even with a small-sized PBX or key telephone device. In particular, even if the number of connected PCs increases, the amount of increase in the load is the same as when one digital multi-function telephone is added, and as will be described later as another embodiment of the invention, the digital multi-function telephone is used together. Considering the case, there is no load on the main device side.

FIG. 7 shows a PC Tel to which the present invention is applied.
FIG. 14 is a block diagram illustrating a configuration example of another embodiment of the ephony system. As shown in the figure, the basic configuration is the same as that of the embodiment shown in FIG. 1. However, in a general PC Telephony system, a digital multi-function telephone is often used in combination. As shown in FIG. 7, in this embodiment, the digital multi-function telephone 300 can be easily used as a telephone provided side by side.

In the configuration example of this embodiment, since the PBX control means 102 uses the I / F of the digital multi-function telephone as it is, the PBX control means 102 receives the LCD (or LED) display information and the voice path received from the private branch exchange 200. Information such as control information and ringer control information is notified to the digital multi-function telephone 300 as it is, and a button press / hook state notification received from the digital multi-function telephone 300 and a button / hook status control received from the main control means 101 Requests should not conflict with each other
The private branch exchange 200 is notified as a button press / hook state notification.

Thus, by providing the PBX control means 102 with the I / F for connecting the digital multi-function telephone 300, the digital multi-function telephone 300 is used together without increasing the load on the main unit at all. It becomes possible.

It is needless to say that the LCD display example in the above embodiment is an example, and the present invention is not limited to this.

Further, in the above embodiment, the personal computer is made to execute various controls and applications, but the present invention is not limited to the personal computer.

[0051]

As described above, in the control system, the control method, and the recording medium according to the present invention, the display information of each frame to be displayed on the display unit of the digital multifunction telephone is sequentially received, and is received immediately before. The change point of the display information of the current frame with respect to the display information of the previous frame is sequentially detected, and the position of the change point of the display information of the current frame is determined with respect to the position of the change point of the display information of the previous frame. When moving in the direction of, the predetermined processing is performed based on the display information of the previous frame, so that the predetermined processing is performed only when the state changes or when the display information is determined. A telephone control system that can operate efficiently and stably can be constructed.
