Abstract

PURPOSE:To surely grasp a time call when an informing time elapses during power failure by backing up a time call registration memory by a battery during the power failure and outputting the content of memory to a specific accessory equipment when the power failure is restored. CONSTITUTION:If a power failure takes place, a memory 5 and a clock 6 are backed up by batteries 7, 8, the content of a time call after registration is held and the clocking operation of time is continued. When the power failure is restored, a microprocessor 3 reads all registered contents in the memory 5, outputs the result to a printer 12 to apply the routine time call processing afterward. Since the time call informed normally is erased after the casting point of time, the time call not informed by the power failure and the time call whose casting time comes after the power restoration are outputted from the printer 12. Thus, as to the time call whose casting time elapses during the power failure, the notice to registered personnels and the registration erasure of the said time call are attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a time call service for a telephone exchange system, and particularly relates to processing of registered time calls during a power outage.

[Conventional technology and problems]

In a telephone exchange system, a time call service is known in which a call time is registered from a telephone to a telephone exchange system, and when the registered time arrives, the telephone exchange system calls the registered telephone. .

Registration of the above-mentioned time call service involves storing the registered telephone extension number and notification time (calling time) in the time call registration memory (consisting of RAM) within the telephone exchange system by dialing on the telephone. It is carried out by

By the way, telephone exchange systems are generally equipped with a power supply blow-up device in case of a power outage, but apart from large-scale systems, in general, in consideration of economic efficiency, the operations performed by the backup device during a power outage are performed using various RAMs.
The battery power consumption is reduced by running one machine to hold the stored data and the currently connected call.

Therefore, in the case of time call service, for time calls whose call time has passed during a power outage,
The registration of the time call is left as is in the time call registration memory without f output processing. In this way, it is inconvenient that the time call that remains without being deleted due to a power outage will be processed after 24 hours have passed unless the power outage is noticed and the deletion operation is performed. For registered time calls that are not processed due to a power outage, it is necessary to notify the person who registered the time call to that effect ( In particular, such notification is essential when providing time call services to hotel guests.) The contents of time call registration are generally unknown, and even if they were known, the occurrence of a power outage would not be recognized. There is also the inconvenience that Tokiji Temple cannot give the above notification.

[Purpose of the invention]

The present invention is proposed to solve the above-mentioned problems, and it is possible to reliably grasp time calls whose notification time has passed during a power outage. The purpose of this invention is to obtain a checking force formula for time call registration contents that will not be forgotten.

[Outline of the invention]

For the above purpose, the present invention backs up the time call registration memory using llf, a during a power outage,
When a power outage occurs again in 11 days, this is detected and the contents of the time call registration memory are output to a specific telephone or an attached device (Siri/4) [Practice of the Invention] Example] The drawings all show embodiments of the present invention, and FIG. 1 is a block diagram, and FIGS. 2 and 3 are first and second embodiments, respectively.
3 is a flowchart showing control of the embodiment.

As shown in FIG. 1, in the telephone exchange system, the IIi section according to the present embodiment includes a call path switch (hereinafter referred to as a switch) 1 that controls connections between tail talkers, etc., and a call delay signal. Generating trumpet 2, turtle story combination / stem system (goods)
A micro-build system that will be used throughout the prefecture 3, a power source 4 that generates operating power for the old exchange system from the squid
, a time call registration memory (hereinafter referred to as "memory") 5, which is composed of a RAM and which registers time calls sent from the telephone, a clock 6 which measures the time, and which punctures the memory 5 and clock 6, respectively, in the event of a power outage. These are batteries 7 and 8, etc.

In addition to the general telephone 9, the above-mentioned telephone exchange system also includes
A telephone 11 with a display 10 and, for example, a printer 12 are housed therein. The communication circuits of the telephones 9 and 11 are connected to the switch 1, and the display 10 and printer 12 of the telephone 11 are connected to the microprocessor 3. Note that the printer 12 can be, for example, a printer of a billing device. Further, the telephone 11 with the display 10 is, for example, a specific telephone installed at a reception desk.

First, the operation of the first embodiment will be explained with reference to FIG.

The microprocessor 4 constantly monitors power outages by monitoring the power supplied from the power source 4, and performs normal time call processing unless a power outage occurs.

This time call process is known as a slow sequence, and an example thereof is shown in FIG. That is, to explain the time call processing shown in FIG. The arrival of the time call calling time is monitored by referring to the time indicated by the clock 6 (ie, current time).

When a time call registration is input from the telephone 9, the microprocessor 3 stores the contents of the manually entered time call, that is, the extension number and notification time of the telephone 9, in the memory 5, and transfers the time call to the memory 5. Registration is complete.

When the notification time registered in the memory 5 arrives, the microprocessor 3 controls the switch 1 to connect the telephone corresponding to the notification time, for example, the telephone 9, to the signal devices 2 and 1, and controls the signal device 2. to output a ringing signal and call the telephone 9.
Sends a call signal to. This time call continues for a certain period of time until a response is received from the telephone 9.
When there is a response or a certain period of time has elapsed, the registration of the called time call is deleted.

The time call processing described above continues unless a power outage occurs, but when a power outage occurs, the power supply from the power supply 4 is cut off, and the telephone exchange system does not have the ability to continue calls that are currently ongoing at the time of a power outage. (The power backup required for this operation is performed by a battery (not shown) attached to the power supply 4.), and the time call processing temple performs processing based on new connection requests that occur during a power outage. Nothing is done.

Furthermore, when a power outage occurs, the memory 5 and clock 6 are back-amplified by batteries 7 and 8, respectively, and the contents of the time call that has been registered up to the time of the power outage are retained and the time counting operation continues. Incidentally, the backup by the battery 7.8 is automatically performed at the same time as a power outage occurs in this embodiment, as in many known battery backup circuits.
Although it is not carried out under the control of the microprocessor 30, the backup of the memory 5 is shown as one of the processing items in FIG. 2 for the sake of clarity in the flow of control.

When the power is restored, the microprocessor 3 detects that the power has been restored by restarting the power supply from the power supply 4, and at this time reads out all the registered contents in the memory 5 [and outputs all the registered contents to the printer 12]. , and thereafter performs normal time call processing. Furthermore, as is clear from the above-mentioned normal time call processing control, the time call that was normally notified is deleted after the time of notification (the time when the relevant telephone is called), so the time call that is output to the printer 12 is the one that was notified due to a power outage. Those that were not notified, and those whose notification time comes after the power is restored.

The printer 12 prints out all the registered contents of the memory 5 outputted above. This allows you to know that a power outage has occurred and all the contents of the time calls that were registered at the time of the power outage, so for time calls whose notification time has passed during a power outage, registrants can be notified and the registration of the time calls can be deleted. can be done.

The registered contents of the memory 5 are, instead of the printer 12,
Alternatively, the information may be output to the display IO of the specific telephone 11 equipped with a display along with the printer 12.

In addition, as shown by the dotted line in FIG. 2, (when performing the process shown by the dotted line, the X-marked part is deleted), the registered time call in the memory 5 is output to the printer 12 and/or the display 10. After finishing, the memory 5 may be cleared to automatically delete all registered time calls. By doing this, it is possible to prevent forgetting to delete the registration of a time call whose notification time has passed. However, for time calls for which the notification time has not passed, it is necessary to re-register them all at once from, for example, a specific telephone 11, so this kind of control is difficult to perform when the number of extensions (the number of telephones 9) is relatively small, for example. This is effective for telephone exchange systems where the number of time call registrations is small, and the number of re-registration operations after power outage recovery is therefore small.

Next, the second embodiment will be explained with reference to FIG. At this time, the memory 5 and the clock 6 are kept backed up by the batteries 7 and 8, and the control is the same as in the first embodiment until recovery from a power outage is monitored.

When the power is restored, the microprocessor 3 reads the registered time call from the memory 5. This reading of registered time calls is performed one by one, which is different from the case in the first embodiment.

The microprocessor 3 stores the power outage recovery time from the time indicated by the clock 6 at the time of power outage recovery, and determines whether the notification time of the read registered time call is before or after the power outage recovery time. (A time call before the power restoration time is a time call after the notification time.) Based on this judgment, if the read registered time call is not one whose notification time has passed, K stores the registered time call in the memory 5 (
1), the next registered time call is read out and the same control is performed.

If the time of the read registered time call is before the time when the power is restored, the registered time call must be a time call whose notification time passed during the power outage (for those whose notification time came before the power outage occurred) , as is clear from the time call processing control, the registered time call is deleted after calling the corresponding telephone), therefore, control is performed to output this registered time call to the printer 12 and/or display 10,
Thereafter, the microprocessor 3 deletes the outputted registered time call from the memory 5.

The registered time call outputted as above is printed out by the printer 12, or by the specific telephone 11.
is displayed on the display 10.

The above control is performed for all registered time calls registered in the memory 5 when the power is restored, and when this is completed, normal time call processing is resumed.

This second embodiment differs from the first embodiment in that when a time call is unexecuted after the notification time has elapsed during a power outage,
The first embodiment is also more convenient because it does not require the specific IT telephone 1 to delete the registered time call or re-register the time call. However, since the processing is complicated, the second embodiment is suitable for a relatively large-scale telephone exchange system in which the number of extensions is relatively large and therefore the number of time call registrations is expected to be large.

〔Effect of the invention〕

As explained above in detail, the present invention is designed to automatically output the contents of the time call registration memory when a power outage is restored. Because you can clearly understand the time call,
This makes it possible to accurately notify time call registrants who requested the time during a power outage, and to avoid inconveniences such as time call registrations remaining after the notification time and time call calls being made 24 hours later. The invention has great effects on time call services.
