BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address setting method for repeaters in a disaster prevention system.

0002

[Prior Art] In a disaster prevention system using time-division multiplex transmission, a receiver has access to a repeater with a unique address or a sensor with an address using a time-division multiplex transmission signal, and sends back monitoring information. , or provide control data. When the receiver receives monitoring information from a repeater connected to a sensor line or a sensor with an address, it displays the district, sounds the district bell, or controls the smoke prevention equipment in conjunction. , Therefore, the receiver is equipped with a table showing the interlocking relationship.

0003

[Problems to be Solved by the Invention] By the way, in conventional systems, unique addresses are arbitrarily set for each address, so creating a table of correspondence relationships is troublesome, and it is difficult to determine whether there is an interlocking relationship by looking only at the addresses. There was a problem that it was difficult to manage addresses.

The present invention has been made in view of the above-mentioned problems, and its purpose is to enable a control repeater and an alarm repeater that are in an interlocking relationship to be regarded as having the same address. To provide an address setting method for a repeater in a disaster prevention system that allows setting, facilitates monitoring and control processing at a receiver, and facilitates address management.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides an address to a repeater or a sensor with an address set with a unique address by multiplex transmission from a receiver via a transmission line. A transmission signal consisting of data, control data, and a reply standby signal is sent, and the repeater whose set address matches the received address data takes in the control data, and also receives monitoring information via the transmission line during the reception period of the reply standby signal. In a disaster prevention system that uses multiplex transmission to return reply data to a machine, an address area and an identification address area are provided as the address of the repeater,
An interlocking relationship in which the district bell and smoke prevention equipment are controlled by the setting address in the setting address area of the alarm repeater connected to the sensor line and the control data from the receiver based on the monitoring information from the repeater. The address in the set address area of the control repeater in It is something that is transmitted.

[0006]

[Operation] According to the present invention, the interlocking relationship between the alarm repeater and the control repeater can be set simply by matching the addresses in the setting address areas, and the receiver side can set the interlocking relationship between the alarm repeater and the control repeater. Interlocked control can be performed simply by accessing control repeaters with the same address based on monitoring information from. Therefore, the same processing as that for a repeater having both a control function and an alarm function can be performed.

The control repeater 21 is the same as the R-type repeater 20 without the monitoring circuit 63, and there are two types of control outputs and one with one control output, and the control target is the R-type repeater 20. Similarly, there are district bell 50 and smoke prevention equipment. The monitoring repeater 22 omits the control output circuit 64 from the R-type repeater 20, and the monitoring circuit 63 has a function of taking in a non-voltage signal or a voltage signal as a monitoring signal.

The voltage applied to the line lc is lowered to a constant voltage based on the control data of , and the transmission signal Vs shown in FIG. In addition, a signal conversion circuit 6 has a function of converting the reply signal of the addressed sensor 32 superimposed on the line lc into a reply signal VB corresponding to the transmission line Vs.
It differs in that it has 5.

The addressable sensor 32 basically includes a transmission system circuit similar to that of the monitoring repeater 22, and receives the transmission signal Vs superimposed on the line lc so that the address data of the transmission signal Vs is set to the set address. This is an analog sensor that captures control data when it matches the above, and also sends the sensed information from the sensor part as monitoring information as a reply signal.It is an analog sensor that outputs analog data such as smoke concentration and temperature that it senses as sensed information. There are also sensors that turn on when the sensing sensor section senses smoke concentration, temperature, etc. above a certain level, and outputs this on-operation signal as sensing information.

(A signal sent by short-circuiting the transmission line Ls via an appropriate low impedance) Return signal V
It is designed to reply as "Reply as B". A transmitter with an address (not shown) also operates in a similar manner.

In the receiver 1, the repeater 2 is connected as described above.
0 to 24 and a sensor 32 with an address, a corresponding district bell 50, a smoke prevention device 51, and a sensor 32 with an address are provided based on the monitoring information returned from the transmitter with an address to the receiver 1. In order to control the confirmation light (not shown), control data to be transmitted to the repeaters 20, 24, 23 and the addressable sensor 32 is created, and the control data is time-division multiplexed and transmitted via the transmission line Ls. It is designed to control each of them.

As shown in c), the identification address area A is divided into an identification address area AD1 and a setting address area AD2.
Write the identification addresses of the repeaters 20 to 24 and the addressable sensor 23 in D1, write an address that the user can arbitrarily set in the setting address area AD2, and use the data in both address areas AD1 and AD2 to form a unique address. When creating an interlocking relationship with each other, that is, when creating an interlocking relationship between the alarm-only relay 20' and the control-only relay 21, the setting address area is used instead of the interlock table. The addresses of AD2 are the same. In other words, when the receiver 1 receives monitoring information from the alarm repeater 20', the control repeater 2 has the same address as the set address area AD2 of the alarm repeater 20'.
If 1 exists, it is assumed that there is an interlocking relationship, and control data is transmitted to perform interlocking control.

[0020] If it is necessary to identify the repeater 20, which has both an alarm function and a control function, and if it is necessary to arrange the addresses in order, a monitor bit is provided. You can identify it by .

Set the same address as the address area of the control repeater that controls the district bell and smoke prevention equipment using the control data from the receiver based on the monitoring information from the alarm relay. Control data is transmitted from the receiver to the control repeater with the same address in the set address area based on the monitoring information from the receiver, so it can be used with the alarm repeater simply by matching the addresses in the set address area. , an interlocking relationship with the control repeater can be set, and the receiver side can perform interlocking control simply by accessing the control repeater with the same address based on the monitoring information from the alarm repeater. The same processing as that for repeaters with both the alarm function and alarm function can be adopted, which eliminates the need for complex monitoring and control processing, and furthermore, it can be determined whether there is an interlocking relationship just by looking at the address in the setting address area. Therefore, the effect is that address management is easy.
