BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data change situation detection device. More specifically, the present invention relates to a device for detecting changes in data that change sequentially within a predetermined range, such as a change in switching status in a switchboard.

As shown in FIG. 6, one type of telephone exchange system includes a switch 50, a switch board 51, a personal computer (hereinafter referred to as a personal computer) 52, and a control package 5.
There is an exchange system that connects 3 and performs exchange operations. In such a system, when an operator transfers an incoming call to the switchboard 51 to a destination telephone, the control package 53 detects the state transition of data sent from the switchboard 50 to the switchboard 51 and performs appropriate switching processing. It is necessary to carry out the following instructions. Therefore, in order to issue commands for various switching processes, it is necessary to detect changes in data sent from the switch 50 to the switch 51.

2. Description of the Related Art When an incoming call to a switchboard 51 is transferred to a destination telephone, the states of the switchboard 51 are approximately: ■ Idle...no incoming call ■ Incoming call...incoming call, but A state in which you are not picking up the phone. ■ On a call... A state in which you have picked up an incoming call and are talking to the other party. ■ On hold... A state in which an incoming call is on hold.
Transferring...It's like an incoming call is being transferred somewhere. These are from one state to another, and
It is a transition from one state to another,
The data handled by the control package 53 changes within six predetermined change ranges, for example, from data "0" to data "5", corresponding to the state transition of the data sent to the switchboard 51.

Therefore, in the control package 53, when the data changes from data "0" to data "1", for example, processing a is performed (for example, the destination of the numeric keypad is switched from the exchange side to the personal computer side, and a list of destinations is displayed on the personal computer 52). ), if the data changes from “1” to “3”, b
It detects changes in data and performs the necessary processing for exchange, such as processing (for example, erasing the list of forwarding destinations that have been displayed so far and displaying the current call status on the display section of the personal computer 52). In reality, there are many types of state transitions and types of processing, but to simplify the explanation here, we will focus on six states from data "0" to data "5", a process, b
This will be explained using four exchange processes: process, c process, and d process.

FIG. 7 shows a flowchart illustrating an example of a conventional data change situation detection method. For example, data “0”
” to data “2” will be explained. In the figure, the control package rewrites the data transition state from the exchange 50 into data that changes within a predetermined range from data "0" to data "5" (step 60), and distinguishes between the state before the change and the state after the change. determine whether they are different (
Step 61), if they are different, the data before the change is "
It is determined whether or not it is "0" (step 62), and since it is "0" in this case, processing a is performed (step 63). Next, determine whether the data before the change is "1" (
Step 64), in this case, it is not "1", so it is determined whether the data after the change is "0" (Step 6
6). In this case, since it is not "0", the data after the change is "
2" (step 68), and in this case, "
2'', the d process is performed (step 69), and the process ends.

On the other hand, for example, from data "1" to data "0"
” will be explained below. In this case, it is determined in step 62 that the data before the change is not "0", and then in step 64, the data before the change is "1".
Since it is determined that
5). Next, in step 66, the data after the change is changed to "
Since it is determined that the data is "0", the c process is performed (step 67), and then in step 68, it is determined that the changed data is not "2", and the process is terminated. In this way, the conventional method requires many discrimination processes (steps 62, 64, 66, 68) to detect changes in data.
and performs respective exchange processing (steps 63, 65, 67, 69) according to changes in data.

[0007]

[Problems to be Solved by the Invention] The conventional example requires a large number of determination processes (steps 62, 64, 66, and 68 in FIG. 7) when detecting data change situations, and as a result, the program in the control package becomes complicated. Therefore, there were problems such as requiring a large amount of processing time, making it impossible to process quickly, and requiring a large memory capacity, resulting in high costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data change situation detection device that can quickly detect change situations and can be realized at low cost.

[0009]

[Means for Solving the Problems] FIG. 1 shows a diagram illustrating the principle of the present invention. In the same figure, reference numeral 73 denotes a discrimination means, in which a plurality of different data change situations (a, b,...) are set in advance in correspondence with discrimination data (Z) of a plurality of situations, and the input situation discrimination data (Z) is the data change status (a, b,...)
Determine whether any of the following apply.

[0010] 72 is a calculation means, which calculates the data (Y) before change.
and changed data (X) are respectively input and the data (
Calculation formula with variables Y, X) (Z=(n+1)X+Y)
The above situation determination data (Z) is obtained by performing calculations based on the above.

[0011]

[Operation] The change situation determination data (Z) is the data change situation (
a, b, ...), and the numerical value (Z = 6.12) in the data table shown in FIG. etc.). This change status determination data (Z)
can be calculated using the calculation formula Z=6X+Y, and data change status can be detected from the Z value.

According to the present invention, a data change situation can be detected simply by calculating the data before the change and the data after the change based on a calculation formula, and there is no need for many discrimination processes to detect the change situation as in the conventional example. The time can be shortened and the memory capacity can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 shows a block diagram of an embodiment of the present invention, showing the inside of the control package 53 in the system configuration diagram shown in FIG. In FIG. 2, 70 is a CPU, which collectively controls the entire system according to the flowchart shown in FIG. A data receiving unit 71 receives data from the exchange 50. Reference numeral 72 denotes a calculation unit that performs calculations using the before-change data (Y) and after-change data (X) received by the data receiving unit 71 to obtain change status determination data (Z). Reference numeral 73 denotes a determination unit that determines which of the a process, b process, c process, and d process to perform, based on the change situation determination data obtained by the calculation unit 72. 74a-74d
are a processing section, a processing section b, a processing section c, and a processing section d, respectively, which execute each process shown in FIG. 4, for example, in response to instructions from the determination section 73. 75 is a data transmitting unit that transmits data to the personal computer 52.

Next, the operation of the present invention will be explained in conjunction with the flowchart shown in FIG.

In the data receiving section 71 shown in FIG. 2, the transition state of the data from the exchange 50 is rewritten to data that changes within a predetermined range from data "0" to data "5" (step 80 in FIG. 3), Subsequently, in the calculation section 72,
Calculations are performed based on the data before change and the data after change that have been rewritten by the data receiving unit 71 to obtain change status determination data (step 81). That is, the data change range is A to B (A<B, that is, data "0" to data "
5''), the state data before the change is Y, and the state data after the change is X, the processing command data Z is Z=(B
-A+1)×(X-A)+(Y-A)=6X+Y. That is, if the data change range is "0" to "n", then Z=(n+1)X+Y.

Although the present invention does not actually use a table, the reason why the above formula holds can be easily understood by creating a data table as shown in FIG. The data table shown in FIG. 5 is a table in which pre-change data Y and post-change data becomes. As shown in FIG. 3, change situation determination data Z is set in advance to correspond to a process, b process, c process, and d process, respectively. For example, if Z=6 is obtained, this is the data for performing a process. This becomes data for determining change status.

For example, a case where data changes from "0" to data "2" will be explained. In the calculation unit 72 shown in FIG. 2, since Y=0 and X=2, Z=6×2+0=
12 calculations (step 81 in FIG. 4), and the determination unit 7
Since Z=12 in 3, it is determined that the data is change situation discrimination data for performing a process and d process (
Step 82), the a processing section 74a and the d processing section 74d perform the a processing and the d processing, respectively (steps 83 and 86).
), the process ends. In this case, as shown in FIG. 4, as process a (state transition to busy), the destination of the numeric keypad 51a of the switchboard 51 is switched from the switchboard 50 to the personal computer 52, and the data transmitter 75 lists the transfer destinations. on the display of the computer 52 (usually the current call status (on hold, etc.)
). In addition, for the d process (state transition from idle to other), the number of telephones currently being handled by the switchboard 51 (up to 10 lines) is set to +1,
If the number of telephones is 1 (there is no telephone handled so far), this is displayed on the display section.

As described above, the present invention can detect the state of data change simply by calculating the state data Y before the change and the state data X after the change based on the above-mentioned formula, and can perform exchange processing accordingly. can be made to do so. In this case, the present invention can significantly reduce the determination process (only step 82 in FIG. 3) compared to the conventional example shown in FIG. It is short and the memory capacity can be reduced, resulting in low cost.

On the other hand, for example, from data "1" to data "0"
” will be explained below. In the above case, in the calculation unit 72, since Y=1 and X=0, Z
=6×0+1=1 (step 81), and since Z=1 in the determination unit 73, it is determined that this is change situation determination data for performing b processing and c processing (step 82), b processing section 74b and c processing section 74
At c, process b and process c are performed, respectively (step 84,
85), the process ends. In this case, as shown in Figure 4,
As process b (state transition from call in progress to other state), the list of forwarding destinations that had been displayed on the display unit is erased, and the current call status (for example, in progress of transfer) is displayed. Also, in the c process (vacant state transition), the number of telephones handled by the switchboard 51 is reduced by -1.
At this time, the number of phones is 0 (there is no phone being handled)
If so, turn off the display to protect the screen.

Note that if the obtained value of X does not match the value shown in FIG.
), no processing is performed and the process ends.

[0021]

[Effects of the Invention] According to the present invention, since the data change situation is detected using a calculation formula, the detection does not require as much discrimination processing as in the conventional example, and this makes the program simple. , Processing time can be shortened and memory capacity can be reduced, resulting in low cost.
