Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a storage device for a repeater in a disaster prevention system.

[Background technology]

The repeater 1 of the disaster prevention system receives multiple transmission signals from a conventional receiver via a transmission line and returns monitoring information and controls connected gas detectors, fire detectors, smoke prevention equipment, etc. As shown in Figures 8a and b, there is a terminal block 2 that contains the necessary electronic circuits and externally connects the power line from the receiver and the transmission line, and the terminal that inputs the signal from the sensor and the display. It had a single functional structure, including a terminal block 3 provided with terminals for connecting lights or other repeaters. For this reason, conventionally each was installed and wired on the switchboard, which not only increased the installation space but also complicated the installation work.Furthermore, it was necessary to tamper with the wiring to replace it in the event of a failure. There were problems such as it was difficult to inspect the circuit and maintenance and inspection was difficult.

[Purpose of invention]

The present invention was developed in view of the above-mentioned problems, and its purpose is to create a disaster prevention system that allows for easy installation and maintenance of repeaters, easy maintenance and inspection, and a reduction in installation space. To provide a repeater storage device.

[Disclosure of invention]

The present invention is a relay for a disaster prevention system that receives multiplex transmission signals from a receiver 4 via a transmission line 5 and returns monitoring information of connected gas detectors, fire detectors, smoke prevention equipment, etc. and controls them. The devices 1a, 1b, . . . have a card configuration consisting of a wiring board 6,
A mounting part for attaching and detaching a plurality of repeaters 1a, 1b..., a terminal block 3 for connecting external control outputs from the attached repeaters 1a, 1b... and monitoring inputs to the repeaters, and other storage devices. is equipped with at least a power line 9' and connectors 8a and 8b for sending and wiring the transmission line 5', and, if necessary, a terminal block 2 for connecting the transmission line 5 and the power line 9 from the receiver 4. It is characterized by the fact that it is equipped with

The present invention will be explained below with reference to embodiment figures.

Embodiment FIGS. 1 and 2 show the main storage device A, and FIGS. 4 and 5 show the subordinate storage device B. The only difference is whether or not it is equipped with a terminal block 2 for connecting the main transmission line 5 and power line 9 sent thereto, or for sending and connecting them to others, and other functions are basically the same. Furthermore, the repeater used in the present invention is a so-called card, as shown in FIG. 3, in which the necessary electronic circuits are wired on a wiring board 6, and an edge connector 10 is provided in the center of the lower part of the wiring board 6 to connect to an external circuit. The card-like repeaters of the embodiment include a repeater 1a corresponding to a fire detector and a repeater 1 corresponding to a gas detector.
b. Repeater 1c that supports control and monitoring of smoke prevention equipment
is prepared.

Each of the storage devices A and B has four receiving connectors 12 which electrically connect and mechanically hold edge connectors 10 in a detachable manner so that four repeaters can be connected to the central part of the device main body 11. There are two side by side. On both sides of this receiving connector 12 arrangement part, there are terminals for connecting signals from the sensor to the repeaters connected to each receiving connector 12, terminals for connecting control signals from the repeaters to external equipment, etc. A terminal block 3 is provided corresponding to each receiving connector 12. The connectors 8a and 8b are connectors for sending and wiring the branched transmission line 5' and power line 9' between the other storage devices A and B, and
In this case, cables 13a and 13b are provided for sending and receiving, respectively, and in storage device A, cables 13a and 13b are provided only for sending, and the transmission line 5 and power line 9 connected to the terminal block 2 are provided.
Connectors 14a and 14b are provided for connection via. 15 is a cover for covering the repeater connected to the receiving connector 12, 16 is a guide rail corresponding to the wiring board 6 of the repeater, and 7 is a hook for fixing the guide rail 16.

Then, as shown in FIGS. 6a and 6b, repeaters are installed as necessary. In other words, Fig. 6a shows the case where three of the various repeaters 1c, 1a, and 1b described above are installed and one receiving connector 12 is left empty, and Fig. 6b shows the case where two repeaters 1b are installed. It shows. Of course, the combination of repeaters and the number of installed repeaters may be changed as necessary, and FIG. 6 merely shows an example thereof.

FIG. 7 shows an arrangement example, in which each switchboard C is equipped with one storage device A, two storage devices B,
The storage devices A in each distribution board C are connected by a transmission line 5 and a power line 9 from the receiver 4, and the storage devices A and B in each distribution board C are connected by a transmission line 5' and a power line 9'. combined. Here, the transmission line 5',
The power line 9' consists of a flat cable with connectors at both ends, and includes connectors 14a, 14.
b can be easily attached and detached.

[Effect of idea]

This invention is a repeater for a disaster prevention system that receives multiple transmission signals from a receiver via a transmission line and returns monitoring information and controls connected gas detectors, fire detectors, smoke prevention equipment, etc. The card has a card configuration consisting of a wiring board, and includes a mounting part for detachably mounting a plurality of card-like repeaters, a terminal block for connecting external control output from the mounted repeater and monitoring input to the repeater; The other storage device is equipped with at least a power supply and a connector for sending and wiring the transmission line, and is also equipped with a terminal block to connect the transmission line and power line from the receiver as necessary, so it can be connected directly to the repeater. Compared to the case where a terminal block is provided and transmission lines and power lines are connected to this terminal block, the arrangement of the repeater is extremely simple, and the feed wiring can be easily performed by using a connector. Because it is not installed on the device, wiring work can be done only on the storage device side with the repeater removed during installation, which has the advantage of preventing damage to the repeater during construction, and the repeater is installed in the form of a card. Since the configuration allows the repeater to be detachably attached to the unit, it has the advantage of making it easy to replace and check the repeater, making maintenance and inspection easy.In addition, since multiple repeaters can be attached, repeaters can be freely combined. It is also possible to create a desired system by using this method, and furthermore, since a plurality of card-shaped repeaters can be installed, there is an advantage that the installation space for the repeaters can be reduced.
