Abstract

PURPOSE:To rapidly print out the information of the generation of abnormality for which an emergency counterpart is required, by providing a timer which supplies present time information to a control part in succession, and a means which sets a specific time zone and a reception delay time corresponding to the specific time zone at the control part from the outside. CONSTITUTION:When the arrival of a call signal is detected, it is judged that a time zone is the one of daylight or the one of night, and the number of times of corresponding call signals is set as a value for operating. And the off-hook of a telephone set is monitored, and also, the number of times of the call signals is counted, and when the number of times reaches a set value, a state is moved to a data communication possible state. Thus, it is possible to input and store the range of a daylight time zone and a night time zone and the number of times of calls by a monitoring person oneself from a key input apparatus 7 to the control part 5, and for example, if the number of times of calls for the daylight time zone is set as 20 times and that of the calls for the night time zone as two times, a call bell rings for 20 times, therefore, the monitoring person can raise the handset of the telephone set 3 when the monitoring person is present.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is for centrally monitoring the status of, for example, automatic water supply systems for buildings installed in multiple locations at one monitoring center using general telephone lines. The present invention relates to a monitoring device.

BACKGROUND OF THE INVENTION First, the overall configuration of this type of monitoring device will be explained with reference to FIG. In FIG. 3, a portion surrounded by a broken line 21 is a water supply device installed in a building such as an apartment complex, and is located in one building. The part indicated by the broken line 22 is a similar water supply system placed in another building. Broken line 2
1, 23 is an automatic water supply device, and 24 is a water leakage detector provided near the automatic water supply device 23. Reference numeral 25 denotes a transmitting device that encodes the status of the automatic water supply device 23 and the detection output of the water leakage detector 24 and sends it to the telephone line. Sensors installed in each part of the automatic water supply device 23 sequentially output detection signals to the transmitting device 25, and detect abnormal water increases and decreases in the water receiving tank, abnormal water increases and decreases in the elevated water tank, leakage in the electrical system, and pressure in the pipes. Information such as an abnormal drop in power and failure of the electric pump is immediately transmitted to the transmitting device 25.

In addition, information indicating that water leakage has occurred is transmitted from the bent water detector 24 to the transmitting device 25. When the transmitting device 25 detects the above abnormality, it encodes the information and transmits it to the monitoring center via the telephone line. Reference numeral 26 denotes a normal telephone set, which is connected to a calling bag e25 and a calling phone n27.

Reference numeral 28 denotes a receiving device installed in the monitoring center, which outputs information sent from the monitoring devices at each location via a telephone line to a printer or the like to notify the monitoring staff.

A normal telephone set 36 can be connected to the receiving device 28, and by switching an internal switch, it is possible to talk between normal telephone sets via the telephone line 30.

FIG. 4 shows the configuration of the receiving device 28, in which 31 is a telephone terminal switch. 32 is a modem that separates binary data from the FSK signal sent via the telephone line. Note that the receiving device 28 may also send response data to the transmitting device 25, and the modem 32 also has the function of sending the response data to the telephone line in the form of a signal. 3:3 is a control unit that controls the switching device 31 and also controls the printer 34 based on data from the modem 32 to output data. 35 is a key for inputting information and commands to the control unit 33 from the outside. 36 is an ordinary telephone connected externally to the receiving device, as described above, and can be connected to a telephone line by means of a switch 31.

The operation of the monitoring device configured as above is as follows. That is, if any abnormality occurs in the water supply device, the transmitting device 25 automatically dials the telephone number of the monitoring center. Normally, on the receiving device side, the switch 31 connects the telephone line to the telephone 36 side, and the telephone line 11
The calling signal sent from the telephone 36 is transmitted to the telephone 36, and the telephone 36 rings a ringing bell. On the other hand, the control unit 33 counts the ringing signals sent intermittently at approximately 2-second intervals, and when the ringing signals reach a predetermined number of times without the telephone 36 being off-hook, it controls the switch 31 to make the call. The line is connected to the modem 32, and the receiving device itself is put into an off-hook state so that it can receive signals. And transmitting device 2
5 (01). Immediately upon receiving this incoming call response signal, the transmitting device 25 encodes the information detected by each sensor and sends it out one after another as an FSK signal. The receiving device receives this signal. is received, and its contents are immediately sent to the printer 34 to be printed out.

On the other hand, even if the telephone 36 is taken off-hook by the supervisor before the ringing signal reaches the predetermined number of times, the supervisor learns that the incoming call is an automatic call from the calling device 25, and then calls the telephone 36 by the supervisor himself/herself. By pressing the manual switching key 37, it is possible to switch the switching device 31 to the modem 32 side and shift to a state in which signals can be received.

By the way, the reason why the normal telephone 36 is connected to the receiving device 28 is to use the wooden telephone line to receive signals from the transmitting device 25 and to make calls from other normal telephones, such as the telephone 38 in FIG. This is because it can be used for voice calls in the event of a call.

Therefore, the receiving device does not respond immediately to the calling signal, but first rings the calling bell of the telephone set 36 to give the guard an opportunity to go off-hook. If the call is from a regular telephone 38, the supervisor can take the telephone 36 off-hook and a voice call can be made.

Problems to be Solved by the Invention However, in the above configuration, the time it takes for the telephone 36 to transition to a signal receiving state without going off-hook from the first arrival of a ringing signal or the number of ringing signals is determined by the supervisor. The value must be set to a sufficiently large value so that the person does not approach the telephone 36 in a hurry and pick up the handset of the telephone 36. If this occurs, the system will enter the state where it can receive signals until the end of the set time has completely elapsed since the first call signal arrives, even though the information communication is urgent. , time will be wasted until the signal is received.Furthermore, if abnormalities occur in multiple water supply devices in a short period of time, the information from the calling device that made the call first will be lost. Although the information is printed out relatively quickly on the receiving device side, the information from the calling device that made the call later is printed out after a long opening period, which is very inconvenient.

The present invention has been made in view of the above problems, and
It is an object of the present invention to provide a monitoring device capable of quickly printing out information on the occurrence of an abnormality in a device on a receiving device connected via a telephone line.

Means for Solving the Problems The present invention provides a timer that sequentially provides current time information to a control section, and means for externally causing the control section to set a specific time period and a reception grace period corresponding to that time period. If there is an incoming call in the first time period, the control unit shifts to the ready state after the reception grace period corresponding to the first time period has elapsed from the arrival of the first calling signal, and When there is an incoming call during the time slot, the control unit is configured to shift to a receivable state after a reception grace period corresponding to the second time slot has elapsed from the arrival of the first calling signal.

Effect By configuring as described above, it is possible to shorten the reception delay time in a specific time period that is preset according to the convenience of the watchman, and in that time period, the system is ready to receive the call signal immediately after the arrival of the first call signal. You will be able to move to.

Embodiments Hereinafter, embodiments of the monitoring device according to the present invention will be described based on the drawings. However, since the basic overall configuration is almost the same as the conventional one shown in FIG. 3, the explanation thereof will be omitted. FIG. 1 shows the configuration of a receiving device installed at a monitoring center in the monitoring device of this embodiment. In FIG. 1, 1 is a telephone terminal switching device, and 2 is a modem, which are constructed in the same manner as the switching device 31 and modem 32 in the conventional example. Reference numeral 3 denotes an ordinary telephone connected to the receiver in the same manner as in the conventional example. The switch 1 connects the telephone 3 to the telephone line,
The modem 2 is also switched and connected to the telephone line. Reference numeral 4 denotes a clock section that outputs time information, and the time information from the clock section 4 is constantly sent to the control section 5. 6
is a display device that displays the time based on time information from the timer section 4. 7 gives commands to the control unit 5 from the outside,
These keys are used to input data necessary for control. 8 is a manual switching key for forcibly operating the switching device 1 from the outside. When the manual switch key 8 is pressed while the contact of the switch 1 is folded down to the telephone 3 side and the telephone 3 is used for a telephone call, the control unit 5 follows this and switches the switch 1 while keeping the line closed. As the contactor is moved toward the modem 3 side, data communication via the modem 2 becomes possible. Numeral 10 is a printer for printing out sent information as in the conventional example.

Next, the control procedure of the control section 5 when receiving a call will be explained according to the flowchart shown in FIG. Before an incoming call occurs, that is, when in a standby state, the contacts of the switching device 1 are bent toward the telephone 3 side. First, when the arrival of a calling signal is detected in step 11, it is then determined in step 12 whether the time at that time is daytime, that is, daytime, or nighttime, that is, night time. If it is daytime, a pre-prepared number of ringing signals corresponding to the daytime is set as a value for actual operation (step 13).

On the other hand, if the time is in the nighttime zone, a pre-prepared number of ringing signals corresponding to the nighttime zone is set as a value for actual operation (step 14). Then, it monitors off-hook of the telephone 3 (step 15), counts the number of ringing signals, and determines whether the number has reached the value set in step 13 or step 14 (step 16). It will be done. Steps 15 and 16 are repeated unless the telephone 3 goes off-hook, and during this period the telephone 3 continues to ring. If the telephone 3 is off-hook before the number of ringing signals reaches a predetermined value, the control section 5 detects this, moves from step 15 to step 17, and repeats steps 17 and 18. When the telephone 3 is taken off-hook, the DC loop is closed through the telephone 3, so that the line is completely connected and the telephone 3 can be used for communication. In step 17, if the manual switching key 8 is pressed, the process moves to step 19, where the modem 3 overrides the contacts of the switching device 1 and enters a state in which data communication is possible. On the other hand, if the telephone 3 is taken off-hook without the manual switching key being pressed, the process moves to step 20 and the line is released.

In the receiving device configured as described above, the daytime and nighttime ranges, the number of calls during the daytime, and the number of calls during the nighttime are input by the lifeguard himself into the control unit 5 from the key manpower device 7 and stored. I can do things. For example, if a lifeguard's working hours are from 8 a.m. to 1 p.m.
If it is 0:00, then the daytime period is 8:00 a.m. to 10:00 p.m.
Set the time from 10:00 pm to 8:00 am the next day as a night time zone.
It is a good idea to set the time. For example, if the number of rings during the night is set to 20 and the number of rings during the night is set to 2, the ringing bell will ring at least 200 times when the guard is present, so the guard will not be in a hurry and will call the telephone 3. You can pick up the receiver. On the other hand, during times when no watchman is present, the call bell only rings twice and the data communication state is immediately enabled, so the wasted time due to the ringing of the call bell is extremely short.

If the guard picks up the handset of telephone number 3 during the daytime, it may be a call from another normal telephone or a third party.
As shown in the figure, if the call is made from the telephone 26 connected to the T-talk line together with the transmitter 25, the call will continue, but if the call is made from the telephone 26 connected to the T-talk line together with the transmitter 25, the call will continue. If it is determined that it is a call, the monitor can manually switch the line on the spot and make it possible to communicate again. It is possible to distinguish whether the call is from a normal telephone or from the transmitting device of the monitoring device by the presence or absence of a carrier signal, but in this embodiment, once the line connection is completed by off-hooking the telephone 3, First, the transmitting device sends the voice information ``Seppi Ijodesu Kakunin Switch Ire Tekudasai'' using synthesized voice. By listening to the voice information, the observer can easily know that it is coming from the transmitting device.

In addition, in this embodiment, counting the time from the arrival of the first paging signal until the transition to the receivable state is replaced by counting the number of paging signals that are sent intermittently about every 2 seconds. However, it is clear that the built-in timer can be used to accurately count time.

Effects of the Invention The present invention includes a timekeeping section that sequentially supplies current time information to the control section, and means for externally causing the control section to set a specific time period and a reception grace period corresponding to the time period. If there is an incoming call during the time slot, the control unit changes the reception ready state after the reception grace period corresponding to the first time slot has elapsed from the arrival of the first ringing signal, and receives the call during the second time slot. If there is a call signal, the control unit is configured to enter the reception ready state after the reception grace period corresponding to the second time period has elapsed from the arrival of the first call signal. It is possible to shorten the reception grace period during specific preset times, for example, during off-duty hours when the monitor is not present, and when the monitor is not present and calls are made using a normal telephone. This prevents the telephone from ringing unnecessarily for a long time during unexpected hours. This makes it possible to quickly print out information on the occurrence of an emergency on the receiver side.
