Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for connecting a monitoring device and a control device to a disaster prevention monitor panel via a repeater with a transmission line, and connecting the control device directly with a control line. It relates to a connected disaster prevention monitoring device. 2. Description of the Related Art As a conventional disaster prevention monitoring device, for example, the one shown in FIG. 5 is known as a P-type facility. In FIG. 5, reference numeral 1 denotes a receiver, and the receiver 1 includes a line receiving circuit unit 2, a line control circuit unit 3, and a control unit 4 for controlling them.
Having. The line receiving circuit unit 2 is provided with a plurality of line signal receiving circuits 5A to 5N, and the line control circuit unit 3 is provided with a plurality of line control signal output circuits 6A to 6N. [0003] For example, one or a plurality of fire detectors 7 are connected to the line signal receiving circuit 5A, and the line signal receiving circuit 5B
Is connected to one or more gas sensors 8, for example.
That is, one or more fire detectors 7 and one or more gas detectors 8 are connected by pulling out the detector lines 9 and 10 from the receiver 1, and the receiver 1 performs a fire detection signal or gas detection on a line basis. Receive and process signals. Further, for example, a district bell 11 is connected to the line control signal output circuit 6A, and the line control signal output circuit 6B
Is connected to, for example, a smoke release shutter 12. That is, the control lines 13 and 14 are pulled out from the receiver 1 and one or a plurality of control devices (the area bell 11, the smoke release 1
2) is connected, and the receiver 1 drives the control device for each line. However, in such a disaster prevention monitoring device, since the monitoring signal is received in units of lines and the control device is controlled in units of lines, the number of lines drawn from the receiver 1 increases. Also, the number of line signal receiving circuits 5A to 5N and line control signal output circuits 6A to 6N provided in receiver 1 increases. As a disaster prevention monitoring device for solving such a problem, one shown in FIG. 6 is known as an R-type facility. This disaster prevention monitoring device connects a terminal device to a receiver via a repeater via a transmission line, and performs monitoring and control by data transmission via a transmission line. In FIG.
Reference numeral 15 denotes a receiver. The receiver 15 includes a transmission control circuit 16 and a control unit 17 that controls the transmission control circuit 16. A transmission line 18 is led out to the receiver 15, and an addressable type sensor 19, a repeater 20 for the detector, a repeater 21 for the bell, and a repeater 22 for smoke control are connected to the transmission line 18, respectively. An on / off type sensor 23 is connected to the device 20, a district bell 24 is connected to the bell repeater 21, and a smoke release 25 is connected to the smoke prevention repeater 22. The addressable type sensor 19 has a function of a repeater, assigns an address to the addressable type sensor 19, designates an address from the receiver 15, sends a response request command, and sends an addressable type sensor. When the addresses match, the sensor 19 returns fire information and the like at that time to the receiver 15. Similarly, an address is assigned to the sensor repeater 20, an address is specified from the receiver 15, and a response request command is transmitted. When the addresses match, the ON / OFF type sensor 23 at that time matches the address. The detected fire information and the like are transmitted to the receiver 19. Addresses are also assigned to the bell repeater 21 and the smoke suppression repeater 22, respectively.
Sends a control command specifying an address, and when the addresses match, the bell repeater 21 and the smoke-control device 22 drive control the connected bell 24 or smoke-control release 25. However, in such a conventional disaster prevention monitoring device, in the latter case, all terminal devices other than the addressable type sensor having a relay function are connected via the relay device. Connected by a transmission line,
Even in a place where control using a repeater is not enough, there is no choice but to use a repeater, and there is a problem that the degree of freedom in designing a system is low. [0010] Specifically, when a large-scale extension is performed in a building having the former disaster prevention monitoring device, when changing to the latter disaster prevention monitoring device, all the existing facilities are removed, There was a problem that the system had to be changed to a new one, which increased the system cost. The present invention has been made in view of such conventional problems, and a monitoring device performs monitoring by a transmission line, and a control device performs direct control by a control line in addition to control by a transmission line.
