Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic information collecting system. In recent years, it has become common for the traffic information of exchanges to be collectively collected and monitored and processed at remote locations. For this reason, an information transfer device for transferring traffic information is added to the existing exchange, and this information transfer device collects the traffic information in the exchange by a monitor and transfers it to an information collection device installed at a remote place at a fixed cycle. I am trying to send it.

On the other hand, since the information collecting device collects and monitors the traffic information of a plurality of exchanges, it is desirable that the collected traffic information is collected at the same time. The time of collecting information is determined by the cycle of a timer provided inside and is not synchronized with the time, so the time of collecting traffic information sent from each exchange is mixed. However, if each information transfer device is provided with an accurate time display function, there is a problem that the information transfer device becomes complicated and expensive.

Under the above circumstances, there is a demand for a system capable of collecting the traffic information of each exchange at the same time without providing the information transfer device with an expensive time display function.

2. Description of the Related Art FIG. 4 is a block diagram of a traffic information collecting system, FIG. 5 is a block diagram of a conventional technique, and FIG. 6 is a traffic information transfer sequence diagram of the conventional technique.

FIG. 4 shows n exchanges 10 (EX # 1 to EX #).
The configuration of a traffic information collecting system for collecting traffic information n) in a host machine 30 installed in a remote place is shown. Although the traffic information of the exchange 10 is generated in a control system (not shown) of the exchange, the exchange itself often does not have a function of remotely transmitting the generated traffic information. Therefore, in the system of FIG. The interface adapter 16 is installed in the computer and connected to the information transfer device 20 installed outside.
10 pieces of traffic information are collected and transmitted to the host machine 30 via a LAN (local area network) 40.

FIG. 4 shows an example in which a device called a traffic collection interface device (hereinafter referred to as TCIE) is used as the information transfer device 20 and a workstation (WS) is used as the host machine 30. A computer or personal computer may be used as the host machine 30.

FIG. 5 shows the structure of the main part of each part constituting the traffic information collecting system of FIG. 4, and only one exchange 10 and TCIE 20 are shown. Although the exchange 10 shows only a part of the control system, the central control unit (hereinafter referred to as CC) 11 of the exchange 10 stores the traffic information generated in the process of call processing or the like in the memory (ME) each time.
M) Writing to the traffic information storage unit 14 in 12.

The types of traffic information include a sequential type in which generated information is accumulated as it is and a cumulative type in which already recorded information is updated. C for sequential type
The C11 issues a write command to the memory 12 to sequentially store the newly generated traffic information in a predetermined memory area. However, in the case of the cumulative type, the previous data is overwritten and the CC11 writes the data from the memory 12 to the previous data. There is a method of reading and adding new data or calculating a difference between old and new data and then storing the calculation result in the memory 12 again. In either type, the traffic information sent by the CC 11 from the write command is transferred to the traffic information storage unit of the memory 12 via the bus 13.
Will be written in 14.

The TCIE 20 monitors the information flowing on the bus 13 via an interface adapter (IFA) 16 and stores only the traffic information written to the memory 12 by a write command from the memory (MEM) 25. When written in the section 21, the stored information has the same content as that written in the traffic information storage section 14 of the memory 12 of the exchange.

The exchange 10 also has time information for use in various applications. The exchange 10 shown in FIG. 5 is provided with a hard clock 17, which is also called an absolute clock, and receives correct time information from a center 19 which concentrates maintenance and operation work and corrects it to always maintain the correct time. This time information is used not only for recording the call start time and call end time during a call, but also for various processes.
It is common to use a soft clock 15 inside. Therefore, the hard clock 17 and the soft clock 15 allow the clock management unit to
The CC 11 controls the CC 18 and controls the soft clock 15 to keep an accurate time. As a concrete operation, the CC 11 reads the time of the hard clock 17 at regular intervals, for example, every 0.5 seconds, and writes it to the soft clock 15 in the memory 12 via the bus 13.

The TCIE 20 receives a write command for updating the soft clock 15 via the interface adapter 16 and stores it in the time information storage unit 22 in the memory 25.
At that time, since the latest time information is overwritten on the previous time information, only the latest time information is stored in the time information storage unit 22. Therefore, the current time is stored in the time information storage unit 22 with a maximum error of 0.5 seconds, for example.

As described above, the memory 25 of the TCIE 20
The traffic information and the time information are stored in the memory, and the stored traffic information is sent to the host machine 30 at the cycle set in the timer 23 '. For example, when the transmission cycle is set to 20 seconds, a transmission instruction signal is transmitted from the timer 23 'every 20 seconds, the traffic information stored in the collected information storage unit 21 of the memory 25 is read, and necessary processing is performed. , Is transmitted from the communication processing unit 26 to the LAN 40. At this time, the current time information stored in the time information storage unit 22 is also read out at the same time, added to the traffic information, and transmitted. Therefore, the time information transmitted with the traffic information is TC
It indicates the time when the IE 20 collected the traffic information.

When the host machine 30 inputs the traffic information and time information sent to the LAN 40 via the communication processing section 34, the host machine 30 sequentially stores them in the collected information storage section 32. The stored information is read on the display unit 33, edited to be suitable for display, and displayed on the display device 36. The operator of the host machine 30 can monitor the traffic condition of the exchange 10 by the display device 36.

Next, a traffic information transfer sequence in the traffic information collecting system of FIG. 5 will be described with reference to FIGS. The timer 23 'of the TCIE 20 sends out a transmission instruction signal every 20 seconds as shown in FIG. The TCIE 20 is the traffic information and time information input from the exchange 10 in the first 20 seconds (information A in FIG. 6).
Is stored in the memory 21, and when the transmission instruction signal is transmitted from the timer 23 ', the stored traffic information is read out and necessary processing is performed, and the read time information is added by the same transmission instruction signal and transmitted.

In FIG. 6, the processing time and transmission time of the traffic information in TCIE 20 are shown in, for example, the left edge of the frame described as "A" reads the traffic information and the time information, and the transmission processing of the traffic information is performed. And the right edge shows the point at which transmission has ended. Therefore, the time information added to the traffic information transmitted in A is T _1.00, and this T _1.00 is also information indicating the collection time. For example, "1" of the subscript "1.00" of T indicates the lower digit of the minute of the time information "10:31:00", and "00" below the decimal point indicates a two-digit number of seconds. I shall.

The host machine 30 receives this traffic information.
After receiving the information and storing it in the collected information storage unit 32, the display device
However, the traffic information displayed is not
It was collected at the same time as the traffic information of the exchange.
Is desirable. In this example, host machine 30
Hick information is collected every minute, 00 seconds, 20 seconds, 40 seconds
It is expected that the expected collection time is
_1.00Etc. H _1.00The meaning of the subscripts such as T_1.00etc
Is the same as.

When 20 seconds have passed since the information generated at time A in FIG. 6 was collected, the next transmission instruction signal is sent (), so that the traffic generated and collected within time B is collected. Information is sent with the time information T _1.20 (,). Further, 20 seconds later, the processing for transmitting the collected traffic information that occurs within the time C starts, but this traffic information requires time for editing processing, and 27 seconds after the processing starts, together with the time information T _1.40. It is assumed that it has been transmitted (in FIG. 6).

Although the internal structure of the timer 23 'of FIG. 5 is not shown in the figure, for example, the timer 23' is configured to send a transmission instruction signal every time 1000 pulses of 20 milliseconds are counted (known art). Therefore, detailed description is omitted). The counting of the pulses in this case is performed by a processing unit (not shown) in the TCIE 20, but when the processing of the traffic information takes time as described above, it becomes impossible to perform other processing such as counting of the timer. There may be a delay in the transmission timing of the transmission instruction signal of the timer 23 '.

As shown in FIG. 6, it takes 27 seconds to process and transmit the traffic information of C, and if the transmission instruction signal is sent at time T _2.07 immediately after the end of transmission (), the transmission instruction signal is sent. Since the traffic information is collected until the above, the next traffic information is collected for 7 seconds longer than the time of D, that is, the normal 20 seconds. When the transmission instruction signal is transmitted at time T _2.07 , the transmission processing of the traffic information collected within the time D is started and the traffic information is transmitted together with the time information T _2.07 (,). After that, if it does not take a long time to process the traffic information, the transmission instruction signal is set to 20.
It is sent out every second, but the delay in transmitting the traffic information of D remains as it is, so the collection time of the traffic information in TCIE20 will be 7 seconds later than the collection time expected by the host machine 30 after H _2.00. .

Since such a phenomenon may occur in other exchanges 10 as well, the traffic information sent to the host machine 30 is likely to be different for each exchange. However, timer 2 of TCIE20 in FIG.
Since 3'does not operate in synchronization with the time, it does not autonomously correct the collection time.

[0021]

In the prior art traffic information collecting system, the traffic information collection time is TC.
Although it is determined by the timer 23 'in the IE20, the timing of sending the transmission instruction signal sent by the timer 23' is not synchronized with the time, and even if the collection time is adjusted to a predetermined time, the processing time for processing traffic information However, the collection time of the traffic information sent to the host machine 30 varies depending on the TCIE 20. However, if the traffic information of each exchange 10 collected by the TCIE 20 is not collected at the same time, for example, the traffic charge switching time zone or the traffic that abruptly occurs when an abnormal situation occurs is accurately identified. Inconvenience arises when grasping.

In order to prevent such a problem, if an absolute clock is to be provided in the TCIE 20, the clock management unit 18 of the exchange 10 will be used.
Similarly, since a device of a complicated scale having a time correction mechanism with the external center 19 is required, there arises a problem that economic efficiency is impaired. Another possible method is to monitor the time information input from the exchange 10 to the TCIE 20 and start the transmission process of the traffic information when the predetermined time arrives, but the predetermined time (for example, every 20 seconds) is detected. As a result, the burden on the processing unit is increased, which causes a problem that the scale of the TCIE 20 is increased.

An object of the present invention is to make it possible to correct the traffic information collection time by a simple method.

[0024]

FIG. 1 is a basic configuration diagram of the present invention, showing a basic configuration of a traffic information collecting system to which the present invention is applied. In the figure, 10 is an exchange and 20 is an exchange 10.
An information transfer device that is added to the traffic information generated in the exchange 10 and accumulates the traffic information, and then sends it out to the transmission line 40 at a predetermined cycle; 30 is the traffic information sent from the information transfer device 20 to the transmission line 40; The information collecting device 40 collects the information via the information transferring device 20 and the information collecting device 30.

21 to 24 are provided in the information transfer device 20, and
Is a collected information storage means for receiving the traffic information sent from the exchange 10 at any time and sequentially accumulating it, and sending out the accumulated traffic information to the transmission line 40 when receiving the transmission instruction signal, 22 is constant from the exchange 10. Only the latest time information is stored by receiving the time information sent in a cycle, and the time information stored when the transmission instruction signal is received is stored in the transmission line 40 together with the traffic information sent by the collected information storage means 21. Time information storage means for sending, 23 is a timer that generates a transmission instruction signal and sends it at a predetermined cycle, and when receiving the cycle correction instruction signal, changes one of the predetermined cycles by the instructed time, 24 is When the collection timing correction instruction signal is received from the information collecting device 30 via the transmission line 40, the transmission cycle of the transmission instruction signal is changed by the time indicated by the collection timing correction instruction signal to the timer 23. It is a collection time correction means for sending a cycle correction instruction signal to instruct.

Reference numeral 31 is provided in the information collecting device 30 and compares the time indicated by the time information sent together with the traffic information with a preset reference time so that the time indicated by the time information falls within a predetermined allowable range with respect to the reference time. It is a collection time control means for sending a collection time correction instruction signal for instructing to correct the difference from the reference time to the collection time correction means 24 in the information transfer device 20 via the transmission line 40 when it exceeds.

[0027]

The information transfer device 20 shown in FIG. 1 inputs the traffic information generated at any time in the exchange 10 and sequentially accumulates it in the collected information storage means 21, and also inputs the time information sent from the exchange 10 at a constant cycle. And stores only the latest time information in the time information storage means 22.

The timer 23 generates a transmission instruction signal of a predetermined cycle and sends it to the collected information storage means 21 and the time information storage means 22. When the collected information storage means 21 receives this transmission instruction signal, The accumulated traffic information is sent to the transmission line 40. Further, when the time information storage means 22 also receives the transmission instruction signal, the latest time information stored at that time is sent to the transmission line 40 together with the traffic information sent by the collected information storage means 21.

When the information collecting device 30 receives the traffic information and the time information, it collects the time information from the collecting time control means.
Input to 31 and process the traffic information as appropriate (detailed description of the processing of the traffic information is omitted). The collection time control means 31 compares the time indicated by the input time information with a preset reference time, and confirms whether the time indicated by the time information is within a predetermined allowable range with respect to the reference time. . As a result, when it is detected that the time indicated by the time information exceeds the allowable range, a collection time correction instruction signal for instructing to correct the difference from the reference time is transmitted to the information transfer device 20 via the transmission path 40. To do.

When the collection timing correction means 24 of the information transfer device 20 receives the collection timing correction instruction signal, the cycle correction instruction signal for instructing to change the transmission cycle of the transmission instruction signal for the time designated by the collection timing correction instruction signal. Is sent to the timer 23. When the timer 23 receives this cycle correction instruction signal, it changes one of the transmission cycles of the transmission instruction signal by the instructed time. As a result, the collection time of the traffic information collected by the information transfer device 20 thereafter becomes a time within the allowable range of the reference time set in the collection time control means 32.

As described above, according to the present invention, even if the traffic information is transmitted in the period of the timer 23 which is not synchronized with the time, the traffic information collection time is kept within the allowable range of the reference time by the control from the information collecting device 30 side. Therefore, even when the traffic information is sent from the plurality of exchanges 10, the traffic information is collected at almost the same time.

Further, since the allowable range of the reference time in the above can be set to an arbitrary numerical value by inputting it into the collection time control means 31 of the information collecting device 30 from the outside, the fluctuation of the collection time of the traffic information is arbitrary. It is possible to control in the range of.

First, referring to FIG. 2, the exchange 10
2 and the operation of collecting traffic information and time information in TCIE 20 are the same as those in the prior art described with reference to FIG.

The traffic information and the time information stored in the collected information storage unit 21 and the time information storage unit 22 by monitoring the exchange 10 are sent to the LAN 40 via the communication processing unit 26 every time the transmission instruction signal is output from the timer 23. Sent to. L
The host machine 30 connected to the AN 40 communicates the traffic information and the time information sent from the LAN 40 with the communication processing unit 34.
Through the collected information storage unit 32 and the collection time control unit 31 respectively
Send to. The traffic information stored in the collected information storage unit 32 is sent to the display unit 33 by the processing unit (not shown) and then displayed on the display device 36. This allows the traffic administrator to know the traffic status of the exchange 10.

On the other hand, the time information input to the collection time control unit 31 is TCIE20 as described in the prior art.
However, the collection time control unit 31 compares the time indicated by the time information with a preset reference time, and the time indicated by the time information indicates a predetermined permissible time with respect to the reference time. Check if it is within the range.

As described in the prior art, the TCI
In the case where the traffic information transmission processing at E20 becomes long and the transmission time is extended to the next transmission time, the collection time of the traffic information to be transmitted next may be delayed by that amount.
For such a reason, when the collection time exceeds the allowable range of the reference time, the collection time control unit 31 of the host machine 30 detects this and outputs a collection time correction instruction signal for instructing correction of the difference from the reference time to the communication processing unit. Information transfer device via 34 and LAN 40
Send to 20. For example, if the received time information indicates a time delayed by 7 seconds from the reference time when the allowable range for the reference time is 5 seconds, it means that the time exceeds the allowable range, so the collection time correction instruction signal advances the collection time by 7 seconds. To instruct.

When the collection timing correction processing section 24 of the information transfer device 20 receives the collection timing correction instruction signal via the communication processing section 26, it changes the transmission cycle of the transmission instruction signal for the time designated by the collection timing correction instruction signal. The timer 23 is instructed by the cycle correction instruction signal.

When the cycle of the transmission instruction signal transmitted from the timer 23 is 20 seconds, for example, the timer 23 transmits the transmission instruction signal every time it counts 1000 pulses of 20 milliseconds, as described above. However, when the cycle correction instruction signal is received, the cycle during counting the 20-millisecond pulse at that time is not changed, and then the first counting cycle is performed for the time specified in the cycle correction instruction signal. Change. For example, when the collection timing correction instruction signal instructs the collection timing to be advanced by 7 seconds, the collection timing correction processing unit 24 reduces the counting pulse of 20 milliseconds by 7000 milliseconds ÷ 20 milliseconds = 350, and 650 The timer 23 is instructed by the cycle correction instruction signal to change to the individual number. As a result, the timer 23 sends out a transmission instruction signal when it counts 650 pulses of 20 milliseconds for that period. Therefore, the cycle of the transmission instruction signal is 13 seconds only at that time, but the cycle of the transmission instruction signal thereafter is returned to the predetermined cycle of 20 seconds.

As a result, the time information sent to the transmission line 40 together with the traffic information collected by the transmission instruction signal sent with the cycle changed is the time obtained by adding 20 seconds of the predetermined cycle to the previous time information. The time is shortened by 7 seconds, and the reference time set in the collection time control unit 31 is matched. Since the time information sent after the corrected time information is sent in a predetermined cycle, the time indicated by the time information thereafter matches the reference time, but each time the time of the time information exceeds the allowable range of the reference time, Since the above correction is automatically performed, the collection time is always within the allowable range of the reference time.

FIG. 3 shows an embodiment of a traffic information transfer sequence according to the present invention. Hereinafter, FIG. 3 will be described in detail. Since the operation up to transmitting the traffic information collected within the time C of FIG. 3 is the same as that of the conventional technique described with reference to FIG. 6, TCIE 20 sets the traffic information of C to C. The transmission process of (1) will be described starting from the point of time when it is transmitted in 27 seconds.

If it takes 27 seconds to send the traffic information collected within the time C, the next traffic information collection time is delayed by 7 seconds and the transmission process is also started by 7 seconds (see FIG. 3). . If it does not take a long time to transmit the traffic information collected within the time D, the timer 23 sends out the next transmission instruction signal after the lapse of a predetermined period of 20 seconds, so that the next traffic information is The information collected within the time E is sent 7 seconds later than the initial period as in.

On the other hand, in the host machine 30, 00 seconds per minute, 2
Although it is expected that the traffic information will be collected at the time of 0 seconds and 40 seconds (reference time), the collection time control unit 31 determines the time of the time information sent together with the traffic information of D in FIG. Compare with this reference time. The time information to be compared may be all "hours, minutes, seconds", but it is usually "seconds".
Since the purpose can be achieved only by comparing only the seconds, it is assumed that only the seconds are compared. However,
In FIG. 3, for the sake of explanation, only the first digit of the minute is described (the description method is the same as the sequence diagram of the conventional technique of FIG. 6).

In the example of FIG. 3, the time information sent together with the traffic information collected within the time D is 2.07 seconds (T _2.07 ) compared to the reference time of 2.00 seconds (H _2.00 ). Since it is delayed by 7 seconds and exceeds the allowable range of 5 seconds, the collection time control unit 31 of the host machine 30 detects this and sends a collection time correction instruction signal instructing to advance the collection time by 7 seconds. (See Figure 3). This signal is L
It is received by the collection time correction processing unit 24 of the TCIE 20 via the AN 40. The collection time correction processing unit 24 uses the cycle correction instruction signal to change the number of pulses counted by the timer 23 to determine the cycle of the transmission instruction signal from the normal count value 1000 to 650 by the timer 23 according to the cycle correction instruction signal. Instruct.

When the cycle correction instruction signal is received, the timer 23 is counting the cycle of the next transmission instruction signal.
The count value is not changed from the middle, but is changed when the pulse counting is started thereafter. Therefore, the collection time of the traffic information after sending the traffic information of D shown in is a predetermined cycle of 20 seconds as shown in FIG. 3, and the traffic information collected within the time of E in FIG. The transmission processing start time of is at time T _2.27 , which is delayed by 7 seconds from the reference time H _2.20 . However, since the collection time control means 31 of the host machine 30 is immediately after sending the collection time correction instruction signal, even if the time delay is detected by the time information T _2.27 received together with the traffic information of E, the collection time correction is performed again. It does not send an instruction signal.

When the transmission instruction signal is transmitted at time T _2.27 in FIG. 3, the timer 23 starts counting the period for transmitting the next transmission instruction signal, and the count value at this time is a predetermined value 1.
Change to 650 instead of 000. For this reason, the period after sending the traffic information collected within the time E becomes 13 seconds, which is 7 seconds shorter than the predetermined 20 seconds, and the next traffic information F collection time becomes T _2.40 , which the host machine 30 expects. The time H _2.40 and the seconds will match. Since the cycle is corrected only once, subsequent traffic information, for example, the collection time after the traffic information of G in FIG. 3 becomes the same time as the reference time (FIG. 3).

In the above, the collection time control unit 31 sends the collection time correction instruction signal when the time indicated by the received time information exceeds a certain allowable range with respect to the reference time, and the allowable range is set to, for example, 5 Although the second is set, the allowable range can be changed in the collection time control unit 31 according to the second aspect. When changing the allowable range, when a command for changing the allowable range is input from the keyboard 37 attached to the host machine 30, the operation management unit 35 of the host machine 30 analyzes this command and stores it in the collection time control unit 31. Change the allowable range (details are omitted because this technology is a known technology). With this function, it is possible to arbitrarily set the variation range (accuracy) of the collection time according to the usage conditions.

The embodiment of the present invention has been described above with reference to FIGS. 2 and 3. However, FIGS. 2 and 3 merely show one embodiment of the present invention, and the present invention is illustrated. It goes without saying that it is not limited. For example, T
Even if the CIE 20 and the host machine 30 are connected by a transmission line or line other than the LAN 40 or the host machine 30 is a device other than a workstation, the effect of the present invention does not change, and the input / output of the host machine 30 is not changed. The same applies when the device is not installed individually as the keyboard 37 or the display device 36 but is integrated with the host machine 30. Further, it goes without saying that the effect of the present invention does not change even if the time of the hardware timepiece 17 in the exchange 10 is corrected from other than the center 19.

Further, in the above description, when the collection time exceeds the allowable range of the reference time, the collection time control unit 31 of the host machine 30 indicates the correction time in seconds, and TC
In the collection timing correction processing unit 24 of the IE 20, the timer 23 converts the count value of the pulse to be counted in order to set the transmission cycle of the transmission command signal and instructs, but the part that converts the time command into the pulse count value. It is obvious that the effect of the present invention does not change regardless of whether it is the collection time control unit 31, the collection time correction processing unit 24, or the timer 23.

Further, in the above description, the information to be collected is the traffic information of the exchange, but the principle of the present invention can be applied to an information processing device other than the exchange, and the information to be collected is other than the traffic information. However, it is clear that it can be applied.

[0053]

As described above, according to the present invention,
Even if the information transfer device added to the exchange collects the traffic information by using a simple timer that is not synchronized with the time, even if the traffic information is transferred, the collection time can be matched with the predetermined time under the control of the information collecting device side. Moreover, since the equipment for correcting the collection time is extremely simple, the traffic collection system is not complicated and expensive. That is, the present invention makes it possible to collect the traffic information of a plurality of exchanges at the same time without requiring a large equipment cost, so that the utilization effect of the collected information is significantly improved and the performance of the traffic information collection system is improved. Greatly contribute to.
