Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a comprehensive disaster prevention system that can automatically or manually perform preset control across repeaters even when the system is down.

In the conventional comprehensive disaster prevention system of this kind, as shown in FIG. The display section 12 is operated based on a large amount of information obtained from the receiver body 1 through the transmission path 5, and the command signal from the receiver main body 1 is sent to the transmission path 5 and the transmission control section of the repeater 2. The control terminal 4 is controlled via 23. Further, by manually operating the operating section 13, the control terminal 4 can be similarly controlled. However, if there is a failure in the receiver body 1 or a failure in the transmission line 5 between the receiver body 1 and the repeater 2, or if the system is down during maintenance and inspection of these devices, a fire may occur from the detector 3. In order to prevent the input of
The control terminal 4 was controlled by switching the alarm input information receiving section 22 to be directly connected to the terminal control section 21 through the matrix circuit 26, but the control terminal 4 linked to the alarm input was , although it is common to span multiple repeaters, not just within the same repeater, it is impossible to control across other repeaters, so some control is required. The drawback was that it could only be done.
Furthermore, when the system goes down, even in an emergency, there is no means for human judgment to control the system.

In order to eliminate such conventional drawbacks, the present invention provides a direct monitoring input line and a simultaneous control line, and enables automatic interlock control across repeaters even when the system is down. In the event of an emergency, interlock control can be performed by human judgment, and interlock control can also be temporarily stopped by human judgment.An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the comprehensive disaster prevention system of the present invention, and the same parts shown in FIG. 1 are given the same reference numbers. In the figure, 6 is a monitoring input line that connects the receiver main body 1 and multiple repeaters 2, and is a direct line that is valid only when the system is down.
Reference numeral 7 denotes a discount simultaneous control line connecting the receiver body 1 and a plurality of repeaters 2. Reference numeral 14 denotes an alarm display and its alarm shift output section which are operated by a signal from the monitoring input line 6, and the alarm shift output section is connected to the simultaneous control line 7. 15 is an automatic/manual changeover switch, and 16 is a simultaneous control switch. 27 is a matrix circuit. These operations will be explained below.

When the system goes down, a signal detected by the receiver abnormality detection section 24 connected to the transmission path 5 is sent to the selection switching section 25, and the input information receiving section 22 for alarm input is sent to the selection switching section 25.
is connected to the monitoring input line 6 through the matrix circuit 27, the alarm display and its alarm shift output section 14 are operated, and the alarm is connected to the simultaneous control line 7. At this time, if the automatic/manual changeover switch 15 is set to automatic, the simultaneous control line 7 becomes valid, and the control terminals connected to the plurality of repeaters 2 through the matrix circuit 27 of the plurality of repeaters 2 4 all at once.
At this time, if the automatic/manual changeover switch 15 is set to manual, the alarm display 14 will only be operated and no simultaneous control will be performed.

In addition, if the automatic/manual switch 15 is set to the manual side, in an emergency, the simultaneous control line 7 will be enabled by operating the simultaneous control switch 16 based on human judgment regardless of the status of the monitoring input line, and the simultaneous control line 7 will be activated and multiple relays will be activated. The control terminals 4 connected to a plurality of repeaters 2 can be controlled all at once through the matrix circuit 27.

In this way, even in the event of a failure of the receiver body 1 or a failure of the transmission path 5 between the receiver body 1 and the repeater 2, or during system downtime during maintenance and inspection of these devices, the monitoring input line 6. By providing an alarm display, its transfer output unit 14, and a simultaneous control line 7, it is possible not only to display an alarm, but also to automatically and safely control the control terminals 4 that are set in advance across the repeaters 2. It is possible to control all sides at once. In addition, in case of an emergency, by providing an automatic/manual changeover switch 15 and a simultaneous control switch 16, even when the system is down, human judgment can be made in advance across multiple repeaters 2 via the simultaneous control line 7 regardless of the status of the monitoring input line 6. The set control terminals 4 can be controlled all at once on the safe side. Furthermore, if it is known in advance that false alarms will occur frequently due to construction or other reasons when the system goes down, human judgment can be used to set the automatic/manual switch 15 to manual and only operate the alarm display and its alarm transfer output unit 14. Then, the simultaneous control of the control terminals 4 can be stopped.

In addition, although the matrix circuit 27 was explained in order to preset the control terminal 4 linked to the alarm input, a microcomputer is used to judge the situation of the fire alarm input, output to the monitoring input line 6, and output to the simultaneous control line 7.
It is also possible to perform input from the terminal and control the control terminal 4 more precisely. Moreover, although the explanation has been made using one monitoring input line 6 and one simultaneous control line 7, fine control can be achieved by using a plurality of each.

As explained in the proof above, the present invention provides a monitoring input line, a simultaneous control line, an automatic/manual switching switch, and a simultaneous control switch. Even in the event of a downtime, it prevents the fire notification function and the safety control function of the control terminal that spans multiple repeaters from stopping, and in the event of an emergency, smoke prevention and exhaust control that spans multiple repeaters based on human judgment. It has excellent effects on comprehensive disaster prevention management, such as being able to safely control control terminals for equipment air conditioning equipment, etc.
