Abstract

PURPOSE:To surely transfer an alarm even when a center equipment is busy or an incoming call section of the center equipment is failed in the alarm transfer system in which an alarm is transferred from an alarm collection device using a public line to the center equipment. CONSTITUTION:When an alarm collection device 6 detects an alarm, a control section 11 extracts a telephone number of a center equipment 1 from a telephone number storage section 10 and uses a dialing section 8 to make dialing to the incoming call section 3 of the center equipment 1 via a public line. In this case, when the connection is not available because the center equipment 6 is busy or the incoming call section is out of order or the like, the control section 11 of the alarm collection device 6 extracts a succeeding telephone number from a succeeding telephone number storage section 10 after lapse of a preset time by a timer control section 12 and uses the dial section 8 to make dialing to other incoming call section 3 of the center equipment or an incoming call section 3 of other center equipment to transfer the detected alarm thereto.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm transfer system, and more particularly to an alarm transfer system for transferring alarms over a public line in a system in which alarms are centrally monitored by a central device.

0002

[Prior Art] Conventional alarm transfer methods transfer alarms from an alarm collection device to a center device via a dedicated line, or
I was using a public line as a backup. Furthermore, when a public line is used, the alarm collection device only stores one telephone number of the center device.

0003

In this conventional alarm transfer system, even in a steady state where no alarm is generated, the center device and the alarm collection device must always be connected through a dedicated line. Furthermore, when a dedicated line is not used, there is a problem in that an alarm cannot be transferred to the center device when the center device is busy or when the incoming call section of the center device is out of order.

0004

[Means for Solving the Problems] An alarm transfer system according to the present invention includes an alarm collection device having a transmitting section, a receiving section, a telephone number storage section storing a plurality of telephone numbers, and a timer control section;
Consisting of one or more center equipment having one or more line originating parts and terminating parts, when an alarm occurs and the center equipment is busy, or when the terminating part of the center equipment malfunctions, the public line When the connection cannot be established, the alarm collection device reads the next telephone number by the timer control unit, and
A public line connection is established with another receiving unit of the center device or with another center device.

[0005]

[Operation] The present invention is capable of reliably transmitting an alarm even if one receiving unit of the center device or one center device is busy or out of order, thereby improving the reliability of the entire system. Can be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of an alarm transfer system according to the present invention, and particularly shows a case where the alarm transfer system is comprised of one center device and two alarm collection devices. In the figure, 1 indicates a first receiving section 2, a second receiving section 3, and a first transmitting section 4.
, a center device equipped with a second transmitting section 5; 6 and 7 are a first alarm collecting device and a second alarm collecting device respectively equipped with a transmitting section 8, a receiving section 9, a telephone number storage section 10, a control section 11 and a timer control section 12; an alarm collecting device; 13 is a public line representing the connection from the transmitting section 8 of the first alarm collecting device 6 and the second alarm collecting device 7 to the first receiving section 2 and second receiving section 3 of the center device 1; From the first transmitter 4 and second transmitter 5 of the device 1 to the first alarm collector 6 and second alarm collector 7
This is a public line representing connection to the receiving section 9 of .

Next, the operation of the alarm transfer method with the above configuration will be explained. First, when the first alarm collection device 6 detects an alarm, its control section 11 retrieves the telephone number of the center device 1 from the telephone number storage section 10, and sends a call to the first receiving section 2 of the center device 1 using the transmitting section 8. put on. Here, if the call is not answered due to a busy call, malfunction, etc., the control section 11 passes control to the timer control section 12. Then, the timer control unit 12 controls the control unit 1 after a preset time.
Return to 1. Therefore, the control section 11 extracts the next telephone number from the telephone number storage section 10 and calls the second receiving section 3 of the center device 1 using the calling section 8 . Then, after a call is made and a public line is established, the detected alarm is transferred to the center device 1. Then, after confirming the content of the alarm, the center device 1 determines that there is a possibility that an unnecessary alarm will be transferred from the first alarm collection device 6, the first transmitting unit 4 sends the first alarm collection device 6 to the first alarm collection device 6. The forwarding of the alarm can be stopped by making a call to the incoming call section 9. It goes without saying that the same thing can be done when the second alarm collection device 7 detects an alarm.

FIG. 2 is a block diagram showing another embodiment of the alarm transfer system according to the present invention, and particularly shows a case where it is constructed from two center devices and two alarm collection devices. In the figure, reference numerals 15 and 16 are a first center device and a second center device, respectively, each having a receiving section 2 and a transmitting section 4. The operation of the alarm transfer method with the above configuration is shown in Figure 1.
Of course, it operates in the same way as the transfer operation shown in , but the alarm collection device of this embodiment only changes the telephone number in the telephone number storage unit, and is not aware of whether there are multiple center devices. It is of course possible to do so.

[0009]

[Effects of the Invention] As explained in detail above, according to the alarm transfer method according to the present invention, by providing the alarm collection device with a plurality of telephone numbers, low reliability when using a public line can be solved. Not only that, it can also respond to failures in the center equipment, improving the reliability of the entire system.
This system has the advantage of being flexible and adaptable to any system configuration simply by changing the telephone number.

Claims (1)

[Claims] [Claim 1] An alarm collection device having a public line transmitting unit, a receiving unit, a telephone number storage unit storing a plurality of telephone numbers, and a timer control unit, and one or more public line transmitting units and a receiving unit. When an alarm occurs, in the alarm collection device, the calling unit makes a call to the center device corresponding to the telephone number stored in the telephone number storage unit; When a connection to the center equipment cannot be established, after a predetermined period of time by the timer control unit, the calling unit calls the center equipment corresponding to the next telephone number stored in the telephone number storage unit to establish a public line.
